DETAILED DESCRIPTION OF THE INVENTION

[0066] Hereinafter, the technical solution of the present invention will be described in detail with reference to the accompanying drawings:

Embodiment 1

[0067] With reference to FIGS. 1 to 6, a high-temperature hot air blower capable of gathering energy and generating heat comprises a machine housing 1, a machine housing air inlet 2, a machine housing air outlet 3, an impeller 4, an impeller air inlet 5, an impeller air outlet 6, blades 7, a blade disc 8, an impeller shaft sleeve 9, an impeller inner-side channel 10, a machine housing inner-side channel 11, a radial side wall of the machine housing inner-side channel 12 and an axial side wall of the machine housing inner-side channel 12. The impeller 4 is of a single blade disc structure, the whole impeller 4 is not provided with a front blade disc, the blades 7 are blades of an impeller of a backward flow blower, and the energy-gathering heat generators 13 are adhered with both the radial side wall 12 (including a spiral tongue) of the machine housing inner-side channel 11 and the axial side wall 12 of the machine housing inner-side channel 11. The energy-gathering heat generator 13 comprises a heat generator transmission protective cover 14 made of a resilient nylon thin plate with good flexibility and heat conducting performance, a heat generator friction heat-generation body 15 made of a soft rubber thick plate with good flexibility and damping performance, and a heat generator heat-insulation isolation wall 16 made of a highly tough rubber thin plate with good heat insulation performance. And the heat generator transmission protective cover 14 is disposed outside the energy-gathering heat generator 13 and is loosely adhered with the heat generator friction heat-generation body 15. The heat generator friction heat-generation body 15 is disposed inside the energy-gathering heat generator 13, the outer side surface of the heat generator friction heat-generation body 15 is adhered with the heat generator transmission protective cover 14, and the bottom surface of the heat generator friction heat-generation body 15 is adhered with the heat generator heat-insulation isolation wall 16. The heat generator heat-insulation isolation wall 16 is disposed outer side of the bottom surface of the energy-gathering heat generator 13, the upper surface of the heat generator heat-insulation isolation wall 16 is adhered with the friction heat-generator 15, and the bottom surface of the heat generator heat-insulation isolation wall 16 is adhered with the bottom surface of the side wall 12 of the machine housing inner-side channel; the whole energy-gathering heat generator 13 is connected to the machine housing inner-side channel by means of a heat generator heat-insulation isolation wall 16.

[0068] The machine housing of this Embodiment is of a general low-heat and large-flow structure, the axial size of the machine housing is large, the calibers of the air inlet 2 and the air outlet 3 of the machine housing are large, and the shaft of the motor 21 is connected with the impeller shaft sleeve 9.

[0069] During operation, the motor 21 drives the impeller 4 to rotate at a high speed, the impeller which rotates at a high speed draws in cold air through the impeller air inlet 5 and the machine housing air inlet 2 to produce high-pressure high-speed air flow, and the high-pressure high-speed air flow is discharged from the impeller air outlet 6 to the machine housing inner-side channel 11. During flow process, the high-pressure high-speed air flow in the machine housing inner-side channel 11 continuously impacts the heat generator transmission protective cover 14 of the energy-gathering heat generators 13 on the radial side wall 12 of the machine housing inner-side channel and the axial side wall 12 of the machine housing inner-side channel, so that the heat generator transmission protective cover 14 presses against the heat generator friction heat-generation body 15 and transfers pressure power energy to the heat generator friction heat-generation body 15; and the heat generator friction heat-generation body 15 absorbs the pressure power mechanical energy, and converts it to thermal energy by intense internal layer friction to generate heat. By virtue of the heat insulation effect of the heat generator heat-insulation isolation wall 16, the heat generated by the heat generator friction heat-generation body will not be transferred to the side wall 12 of the machine housing inner-side channel to be dissipated outside the machine housing. The heat generated by the heat generator friction heat-generation body 15 is transferred to the high-pressure high-speed gas in the machine housing inner-side channel 11 through the heat generator transmission protective cover 14, so that the temperature of the high-temperature high-speed gas is increased to produce high-temperature hot air, and the high-temperature hot air is discharged out of the machine housing through the air outlet 3 of the machine housing to be used for other purposes.

[0070] In this Embodiment, the heat generator transmission protective cover 14 of the energy-gathering heat generator 13 is loose, soft and elastic, the heat generator friction heat-generation body 15 is soft, elastic and thick, so when the heat generator transmission protective cover 14 is impacted and collided by high-pressure high-speed air flow, the heat generator transmission protective cover 14 continuously presses the heat generator friction heat-generation body 15 which contracts and rubs against the heat generator transmission protective cover 14, so that the high-speed air flow can be facilitated to continue in one direction under decompression and deceleration, reverse air flow due to collision and friction would not rise from the unidirectional air flow, and thus noise due to collision and friction between the reverse and forward air flow can be avoided. On the other hand, because the heat generator friction heat-generation body has a good damping function, the noise sound wave excited by the high-pressure high-speed air flow originally has certain mechanical energy, and when the noise sound wave impacts the soft and elastic heat generator transmission protective cover 14, the noise sound wave mechanical energy is transmitted through the heat generator transmission protective cover 14 to the heat generator friction heat-generation body 15, so that the heat generator friction heat-generation body 15 generates heat by internal layer friction, with the mechanical energy converted to thermal energy; part of the noise sound waves are thereby reduced and eliminated, resulting in reduced noise by using the machine.

[0071] In this Embodiment, by means of the energy-gathering and heat-generating function of the energy-gathering heat generator 13 through friction, required high-temperature hot air can be produced, with good processing effect, high efficiency, low noise, and being beneficial to environmental protection.

[0072] This Embodiment is suitable for manufacturing the low-pressure high-flow high-temperature hot air blower capable of gathering energy and generating heat for heating, greenhouse cultivation and other applications.

[0073] For simplicity and convenience in processing, in this Embodiment, the energy-gathering heat generator 13 can be directly made of a soft rubber plate, the bottom side of the soft rubber plate is coated with a layer of high-temperature-resistant heat-insulation liquid glue or paint, and is adhered with the side wall of the machine housing inner-side channel through the liquid glue or paint, the liquid glue or paint itself is the heat generator heat-insulation isolation wall 15. The upper surface of the thick rubber plate is coated with a layer of liquid rubber or paint with good high temperature resistance and heat conductivity, or the thick rubber plate is covered by a layer of stainless steel mesh, and the layer of liquid rubber paint or stainless steel mesh is the heat generator transmission protective cover 14.

Embodiment 2

[0074] With reference to FIGS. 7 and 8, this Embodiment is substantially the same as Embodiment 1, with the exception that the impeller blades 7 and the blade disc 8 of this Embodiment are provided with energy-gathering heat generators 13, which have the same structure, function and effect as the energy-gathering heat generator 13 on the side wall 12 of the machine housing inner-side channel.

[0075] The blade 7 is wrapped by the energy-gathering heat generator 13, the energy-gathering heat generator 13 on the blade disc is adhered to the inner side surface of the blade disc, and the energy-gathering heat generator 13 on the blade and the energy-gathering heat generator 13 on the blade disc form a new impeller inner-side channel 10.

[0076] During operation, the high-pressure high-speed air flow produced by the blades 7 at any time impacts the energy-gathering heat generator 13 on the blades 7 and on the blade disc 8 at any time and any place; heat is generated in the whole inner-side channel 10 of the impeller at any time and any place to increase the gas temperature and form high-pressure high-speed high-temperature hot air; the high-pressure high-speed high-temperature hot air is discharged to the machine housing inner-side channel 11 through the impeller air outlet 6, and then impacts the energy-gathering heat generator 13 on the radial side wall and axial side wall of the inner-side channel, so that internal layer friction of the energy-gathering heat generator 13 is caused to generate heat, and the gas temperature is further increased.

[0077] In this Embodiment, the high-speed gas produced by the impeller flows through the impeller inner-side channel 10 and the machine housing inner wall flow channel 11 for twice friction, decompression and deceleration to generate heat, so more heat is generated, and the gas temperature is increased further.

[0078] As in Embodiment 1, by virtue of the damping effect of the heat generator transmission protective cover 14 and of the heat generator friction heat-generation body 15 of the energy-gathering heat generator 13, the noise generated in the operation process of this Embodiment is reduced with no noise pollution.

[0079] This Embodiment is suitable for manufacturing a common hot air blower for heating and warmth-keeping and growth-facilitating for an ecological breeding greenhouse.

Embodiment 3

[0080] With reference to FIGS. 9 to 13, this Embodiment is substantially the same as Embodiment 1, with the exception that the heat generator transmission protective cover 14 of the energy-gathering heat generator 13, which is on the side wall 12 of the machine housing inner-side channel of this Embodiment is of an uneven structure (an abrasion resistant artificial product). The second difference lies in that the heat-gathering heat generators 13 are provided in both the machine housing air inlet 2 and the machine housing air outlet 3 in this Embodiment. The heat generator transmission protective cover 14 of the energy-gathering heat generator 13 in the machine housing air inlet 2 is in an uneven structure, and the heat generator transmission protective cover 14 of the energy-gathering heat generator 13 in the machine housing air outlet 3 is of a smooth and flat structure. The energy-gathering heat generator 13 in the machine housing air inlet and the energy-gathering heat generator 13 in the machine housing air outlet are respectively supported on inner side walls of the air inlet 2 and the air outlet 3 of the machine housing in a lining manner and are adhered with the inner side walls of the machine housing air inlet and of the machine housing air outlet.

[0081] During operation, the negative pressure at the machine housing air inlet 2 is large, cold air is drawn into the machine housing air inlet at a high speed, the high-speed cold air enters the machine housing air inlet 2 and intensively impacts the uneven heat generator transmission protective cover 14 in the machine housing air inlet 2, the uneven heat generator transmission protective cover 14 absorbs the pressure power mechanical energy transmitted by the high-pressure high-speed air flow, on the one hand, to cause intense friction in heat generator transmission protective cover 14 to generate heat; and on the other hand, to press the heat generator friction heat-generation body 15, transmitting mechanical energy to the heat generator friction heat-generation body, causing internal layer friction of the heat generator friction heat-generation body to generate heat; the heat generated by both the heat generator protective cover 14 and the heat generator friction heat-generation body enables the high-pressure high-speed air flow entering the air inlet 2 of the machine housing become high-temperature hot air. The high-temperature hot air is discharged to the impeller 4, processed by the impeller 4 to increase pressure and speed, and then discharged to the machine housing inner-side channel 11 to impact the heat generator transmission protective cover 14 of the energy-gathering heat generator 13 on the side wall of the machine housing inner-side channel, so that the uneven heat generator transmission protective cover 14 generates heat, (intense friction occurs between artificial filaments and wool filaments, and between wool filaments and gas), the heat generator friction heat-generation body 15 generates heat by intense friction, and thus the temperature of the gas is increased. The high-temperature hot air enters the air outlet 3 of the machine housing, subjected to intense friction of the heat generator friction heat-generation body 15 of the energy-gathering heat generator 13 in the air outlet 3 of the machine housing to generate heat, thereby increasing the temperature of the air further, forms high-temperature hot air with higher temperature which is then discharged from the machine body to serve other purposes.

[0082] In the operation process of this Embodiment, the cold air entering the machine body passes through the heat generator transmission protective cover 14 of the energy-gathering heat generators 13 in the machine housing air inlet 2, in the machine housing inner-side channel 11 and in the machine housing air outlet 3, multiplied internal layer friction of the heat generator friction heat-generation body occurs, more heat is generated, and the temperature of the gas is increased higher (>100 C.).

[0083] As in Embodiment 1, the noise generated during operation is low and does not cause environmental pollution.

[0084] This Embodiment is suitable for manufacturing an ultra-high temperature hot air blower in application.

Embodiment 4

[0085] With reference to FIGS. 14 to 16, this Embodiment is substantially the same as Embodiment 3, with the exception that the heat generator friction heat-generation body 15 of the heat-gathering heat generators 13 in the machine housing air inlet 2, in the machine housing air outlet 3 and on the side wall 12 of the machine housing inner-side channel in this Embodiment are composed of a high temperature resistant sponge product. The upper surface of the sponge heat generator friction heat-generation body 15 is of an uneven structure with teeth. The heat generator transmission protective cover 14 on the energy-gathering heat generator 13 is formed by high-strength wear-resistant nylon thread fabrics, the nylon fabric heat generator transmission protective cover 14 is of a creased uneven structure, and the profile of the crease uneven structure corresponds to that of the teeth of the upper surface of the sponge heat generator friction heat-generation body 15. The heat generator heat-insulation isolation wall 16 of heat-gathering heat generator 13 is made of artificial leather with high temperature resistance and good heat insulation performance.

[0086] The second difference lies in that a wind-shielding heat generator 19 is provided in the machine housing inner-side channel 11 in this Embodiment, the wind-shielding heat generator 19 is provided with the energy gathering heat generator 13 thereon, the heat generator friction heat-generation body 15 of the energy gathering heat generator 13 is made of flat sponge, and the heat generator transmission protective cover 14 of the energy gathering heat generator 13 is made of stainless steel mesh.

[0087] During operation, the high-speed cold air drawn in the machine housing air inlet 2 is processed by the internal layer upper surface of the sponge heat generator friction heat-generation body 15 and the heat generator transmission protective cover 14 of the energy-gathering heat generator 13 in the machine housing air inlet 2 to form high-temperature hot air, the high-temperature hot air is pressurized and accelerated by the impeller to form high-pressure high-speed high-temperature hot air, and the high-pressure high-speed high-temperature hot air enters the machine housing inner-side channel 11, passes through the heat generator friction heat-generation body 15 and the heat generator transmission protective cover 14 of the energy-gathering heat generator 13 on the side wall 12 of the machine housing inner-side channel to process again to generate heat, the high-pressure high-speed hot air also impacts the energy-gathering heat generator 13 on the wind-shielding heat generator 19 in the machine housing inner-side channel 11, subjected to the heat generator friction heat-generation body 15 and the heat generator transmission protective cover 14 of the energy-gathering heat generator 13 on the wind-shielding heat generator 19 to process again to generate heat to form the ultra-high-temperature hot air with higher temperature. The high-pressure high-speed ultra-high-temperature hot air is subjected to once again processing heat generation by passing through the friction heat generation body 15 and the heat generator transmission protective cover 14 of the energy-gathering heat generator 13 in the machine housing air outlet 3 to generate heat, the temperature is further increased, the high-pressure high-speed ultra-high-temperature hot air becomes ultra-high-temperature hot air with even higher temperature which is then discharged out of the machine body for use.

[0088] In this Embodiment, the heat generator friction heat-generation body 15 of all the energy-gathering heat generators 13 are made of high-temperature-resistant sponge products, whose damping friction heat-generating effect and sound-reducing effect are better, therefore, more heat is generated, the air temperature increases further (>200 C.) to form ultra-high-temperature hot air with higher temperature; and the noise generated in the operation process of this Embodiment is low, without causing noise pollution.

[0089] This Embodiment is suitable for manufacturing an ultra-high temperature hot air blower (>200 C.) for food processing, industrial product processing and the like.

Embodiment 5

[0090] With reference to FIG. 17, this Embodiment is substantially the same as Embodiment 1, with the exception that the heat generator friction heat-generation body 15 of the energy-gathering heat generator 13 of this Embodiment is made of thick wool. The heat generator friction heat-generation body 15 of the energy-gathering heat generator made of thick wool is internally provided with a gold-containing steel coil spring heat conducting element 17 with good heat transfer performance, and the coil spring heat conducting element 17 transversely passes through the wool heat generator friction heat-generation body and is connected with the heat generator transmission protective cover 14 made of thin nylon plate.

[0091] During operation, the heat generated by the heat generator friction heat-generation body of the energy-gathering heat generator 13 on the side wall of the machine housing inner-side channel is transferred to the heat generator transmission protective cover, and is then transferred by the heat generator transmission protective cover to the gas in the machine housing inner-side channel 11 rapidly, so that the gas in the machine housing inner-side channel is rapidly heated and becomes high-temperature hot air.
