A machine for cleaning regeneration chambers of furnaces, the regeneration chambers having stacks of hollow refractory elements delimiting vertical passages, which define chimneys includes a self-propelled support structure to be introduced into a compartment, below the regeneration chamber to be cleaned, which communicates with the regeneration chamber. The machine further includes at least one lance, applied to the self-propelled support structure and configured to send within the vertical passages a stream of cleaning material powder and compressed air generated by a compressor positioned outside of the regeneration chamber to be cleaned, and at least one suction mouth, applied to said support structure and configured to suck cleaning material dust and aspirable materials from the ground, which were removed during the cleaning operation. At least one video camera is mounted on the support structure and at least one monitor controls from outside, through the video camera, operation of the machine.

A system for cleaning a downspout of an eavestrough system where the downspout comprises a downwardly extending pipe with a bottom discharge portion having a mouth utilizes an air blower system which can be a leaf blower or a shop vacuum with an outlet nozzle. The system includes a connector portion in the form of a flexible sleeve having first and second open ends and a tightening system such as a strap at each end. In use the first end is tightened onto the outlet nozzle of the air blower and the second end is tightened onto the discharge portion at the mouth and the air blower system is operated to drive air through the downspout to expel any collected materials.

The invention relates to a diffusor for adding of gases into water, said diffusor comprising a perforated tube (1) and at least one supply tube (2), said the at least one supply tube (2) is at one end coupled to a source for supplying gas and at the other end in fluid communication with the perforated tube (1), the gas is supplied to the perforated tube (1) through at least one inner supply tube (4; 5; 15) extending from the supply tube (2) to the perforated tube (1). The invention is distinctive in that at the least one inner supply tube (4; 5; 15) is a non-perforating tube and has at least one outlet (4a, 5a, 15a) situated at a free end of the at least one inner supply tube (4, 5, 15), said gas is adapted to be distributed into the perforated tube (1) through the at least one outlet (4a, 5a, 15a).

A foot operated pump includes a water and airtight flexible and collapsible wall between a top plate and a base plate and an interior variable volume chamber. A flexible hose is selectively attachable to either an inlet port or an outlet port on the top plate member. The contents (air and/or liquid) within the variable volume chamber are forced out of the outlet port upon forced downward movement of the top plate member towards the base plate member. As the top plate member returns to a normally relaxed state in separated, angled relation to the base plate, the variable volume chamber enlarges and air is sucked through the inlet port to fill the variable volume chamber. An opposite end of the flexible hose attaches to various adapters and fittings for clearing clogged drain lines and other conduits.

A system and method for cleaning, protecting and lubricating hyperbolic rollers and bearings for bending, using air and oil, placed in a rotating rotor (1) that contains rollers (32) placed on bearings (34) and shafts (33) inside roller housings (30), where rollers (32) are positioned at an angle with respect to the bending axis and, as bending occurs they cause bending and also as rotor (1) rotates around the item being bent it straightens and feeds the item. Rollers (32) are placed on bearings (34) and are protected through rotational seals (35). The bearings' (34) area of rollers (32) inside the rotational seal (35) is supplied with air at pressure higher than the atmospheric, so that inflow of contaminants are inhibited, or is supplied with air enriched with oil so that bearings (34) are lubricated, and rotational seals (35) located next to bearings (34) of the rollers (32) allow the air flow from the area between the bearings towards the surrounding area.

A cleaning method includes a first removal step of causing an inert gas to which a pulsation is applied to flow into an exhaust pipe after a silicon single crystal doped with an n-type dopant is produced, to peel and remove a deposit; and a second removal step of causing an atmospheric air to which no pulsation is applied to flow into the exhaust pipe through a chamber to burn a part of the deposit with the atmospheric air, the part being not removable in the first removal step, and peel and remove a burned substance of the deposit.

Embodiments of the present disclosure provide a purging system for a turbine fracturing apparatus group and a turbine fracturing apparatus group. The turbine fracturing apparatus group includes a plurality of gas turbines, each gas turbine includes a plurality of fuel supply pipelines. The purging system includes: a first air compressor and a purging pipeline, the purging pipeline communicates the first air compressor with the plurality of fuel supply pipelines of each gas turbine in the turbine fracturing apparatus group, and the first air compressor is configured to, in a case where at least part of the plurality of fuel supply pipelines is stopped from supplying fuel, supply compressed air to the at least part of the plurality of fuel supply pipelines which has been stopped from supplying fuel, so as to perform purging.

A machine that includes a cooling package and a method for cleaning debris from the cooling package is disclosed. The cooling package may include a housing, a cooler, a heat exchanger, a conduit, and plurality of nozzles mounted on the conduit. The cooler may be configured to receive heated machine fluid generated by the machine. The heat exchanger may be configured to convey heat away from the cooler and may include a plurality of fins coupled to and extending outward from the cooler. The plurality of fins may define a plurality of channels. The conduit may be disposed between the housing and the plurality of fins. The plurality of nozzles are configured to discharge a fluid on the fins. The fluid may be air or a release agent. In some embodiments, a release agent may be discharged on the fins prior to the discharge of air on the fins.

A gutter cleaning system is disclosed which has an air line for receiving air, a first section having a first end and a second end, the first end adapted to being connected to the air line, the first section having an aperture formed therein, and a head assembly connected to the second end of the first section, the head assembly having an arm portion having an aperture.

A drain clearing air gun includes a housing defining a main body, a handle positioned on a first end of the main body, and a nose positioned on a second end of the main body. A tank is at least partially positioned within the housing and includes a chamber for receiving pressurized air. A motor is positioned within a main body of the housing, and a pump is positioned within the main body of the housing and operatively coupled to the motor. The pump is driven by the motor to pump air into the tank. A pressure gauge is supported by the housing and includes an automatic shutoff feature. The pressure gauge is in fluid communication with the tank. When a predetermined pressure within the tank is reached the automatic shutoff feature is activated to stop the motor.
