DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The present invention is further described below in combination with the drawings and embodiments. In the following detailed description, some exemplary embodiments of the present invention are described only by descriptive means. It is obvious that those skilled in the art may recognize that the described embodiments can be modified in various methods without deviating from the spirit and scope of the present invention. Therefore, the drawings and descriptions are essentially descriptive and are not used to limit the scope of protection of claims.

[0032] As shown in FIG. 1 and FIG. 6, the environment-friendly dust-free desktop cutting machine includes the housing 1 and the cutting work platform 2 arranged on the housing 1. The cutting work platform 2 is provided with the saw opening 3, and the saw blade 4 is installed in the saw opening. The saw blade 4 is connected to the drive motor 5. Referring to FIG. 4, in this embodiment, the cutting work platform 2 includes the main work platform 21 and the embedded block 22, and the saw opening 3 is arranged on the embedded block 22.

[0033] The air intake chamber 6 is arranged under the cutting work platform 2, and the saw opening 3 is configured as an air inlet of the air intake chamber at the same time. The air intake chamber 6 is provided with the air outlet 73 of the air intake chamber (that is, the air inlet of a separator). The semi-annular air intake duct 61 is formed in the air intake chamber 6 along the rotating track of the saw blade, which facilitates the rapid flow of dusty air towards the air outlet of the air intake chamber and avoids the overflow of dust out of the saw opening 3. In this way, it is ensured that the dust emission concentration in the working environment is less than 50 μg/m.sup.3, thereby achieving clean emissions. The horizontal centrifugal separator 7 is installed at the air outlet 73 of the air intake chamber.

[0034] The rear end of the horizontal centrifugal separator 7 is provided with the dust-dropping port 71 of the separator, and the first dust collecting box 81 is arranged at the dust-dropping port 71 of the separator. The front end of the horizontal centrifugal separator 7 is provided with the air outlet 72 of the separator, and the filter cylinder 9 is arranged at the air outlet 72 of the separator. The negative-pressure fan 10 is installed at the air outlet of the filter cylinder 9, and the third dust collecting box 83 is arranged under the filter cylinder 9. After being blew off, the dust filtered by the filter cylinder 9 will drop in the third dust collecting box 83, so that the filter cylinder can be cleaned. The filtration adopts a cylindrical filtration, which has the advantage of providing a large filtration area in a small space.

[0035] Referring to FIG. 2, the air rotation move axis of the horizontal centrifugal separator 7 is parallel to the cutting work platform 2. After entering the housing of the separator, the dusty air spirals and moves forward along the inner wall of the housing, so that the dusty air forms a spiral air flow and moves forward in a fixed direction. When the dusty air is spiraling and moving at a high speed, the vast majority of dust particles in the air flow reach the inner wall of the housing under the action of centrifugal force and are separated from the air. After arriving at the rear end of the separator, the separated dust particles enter the dust-dropping port 71 of the separator in a tangential direction and drop in the first dust collecting box 81, to complete the separation of dust and air. The separated air turns back at the rear end and leaves the separator from the air outlet 72 of the separator. The horizontal structure of the centrifugal separator can reduce the height and size of the equipment, and make the equipment portable.

[0036] During the specific installation, the portion between the lower portion of the embedded block 22 and the main work platform 21 conducts sealing, and the portion between the lower portion of the main work platform 21 and the upper portion of the air intake chamber 6 conducts sealing. The wind generated by the negative-pressure fan 10 can only enter from the saw opening 3 configured as the air inlet of the air intake chamber at the same time, and the operation such as the replacement of the saw blade can be carried out conveniently after the embedded block 22 is removed. During work, a wind speed at the air inlet of the air intake chamber is preferably greater than the linear speed of the rotation of the saw blade 4, so that a high-speed airflow can effectively absorb the dust produced by cutting to enter the air intake chamber 6.

[0037] Referring to FIG. 3, the air discharging chamber 11 is arranged in the housing 1, and the drive motor 5 of the saw blade and the negative-pressure fan 10 are installed in the air discharging chamber 11. The tail end (the portion between C and D) of the air discharging chamber 11 is provided with the air discharging port 12, and the air discharging port 12 is provided with the soundproof cotton 13. The soundproof cotton 13 can effectively reduce the noise generated by the drive motor of the saw blade and the negative-pressure fan. It should be noted that the air discharging port can be arranged between A and B, B and C, as well as C and D in FIG. 3. Preferably, the present invention takes the portion between C and D as the air outlet in order to take away the heat generated by the motor when the wind passes by the surface of the motor, so as to prevent the motor from overheating.

[0038] Referring to FIG. 1, the bottom of the air intake chamber 6 is provided with the large particle outlet 62, and the second dust collecting box 82 is arranged at the large particle outlet 62. Referring to FIG. 6, in this embodiment, the first dust collecting box 81, the second dust collecting box 82, and the third dust collecting box 83 are integrated to be the dust collecting box 8. The first dust collecting box 81 is used to collect the dust produced by the horizontal centrifugal separator, the second dust collecting box 82 is used to collect the relatively large particles in the air intake chamber, and the third dust collecting box 83 is used to collect the dust in the filter cylinder.

[0039] Referring to FIGS. 1 to 3, the working principle of the present invention is as follows: when the saw blade 4 cuts the workpiece 14 at a high-speed rotation, it should be ensured that the wind speed at the saw opening 3 (the air inlet of the air intake chamber) is greater than the linear speed of the rotation of the saw blade 4, so that the high-speed airflow at the air inlet of the air intake chamber can effectively carry all the dust/cuttings produced by cutting to enter the air intake chamber 6, and the dusty air passes through the horizontal centrifugal separator 7 and the filter cylinder 9 to realize the separation of dust and air. Clean air is discharged into the atmosphere through the negative-pressure fan 10. In this way, most of the dust is first separated in the horizontal centrifugal separator 7, and only a small amount of fine dust needs to be filtered. When the filtering material is an efficient filtering material, the dust emission requirement of less than 50 μg/m.sup.3 can be achieved, thereby realizing the clean discharge. Moreover, the filter cylinder is not prone to be blocked, which greatly prolongs the period for cleaning or replacing, thereby ensuring the long-term and stable operation of the equipment.

[0040] The above only describes an exemplary specific embodiment of the present invention and is not used to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the conceptions and principles of the present invention shall fall within the scope of the protection of the present invention.
