[0003] When the air filter inhales dusty air during long-term use, it will cause abnormal wear of the equipment. The inhaled dust will scale on the surface of the filter device and reduce the dynamic balancing accuracy of the equipment, which will seriously affect the operation, working performance and service life of the air power equipment. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides a self-cleaning air filter.

[0005] The utility model is achieved in this way:

[0006] A self-cleaning air filter comprises a filter body and a cleaning mechanism, wherein the filter body comprises a filter cartridge, a cartridge cover and a cartridge bottom, the filter cartridge and the cartridge bottom are respectively mounted on the top and bottom ends of the filter cartridge, the cleaning mechanism comprises a support frame, the support frame is mounted on the inner bottom of the filter cartridge, a pair of cathode columns are mounted on the top of the support frame, a pair of filter elements are supported on the top of the support frame, an opening is formed at the bottom of the filter element, the cathode columns slide in the opening, an anode plate is mounted on the inner wall of the filter cartridge, a wire groove is formed on the outer side of the filter cartridge, a water outlet is formed at the bottom center of the cartridge bottom, a water outlet pipe is connected to the water outlet, and a solenoid valve is connected to the bottom end of the water outlet pipe.

[0007] The beneficial effect of adopting the above further scheme is that the wires of the cathode column are connected to the power supply by using the wire trough, and the wires of the anode plate are grounded. At this time, a high-voltage electrostatic field is formed between the grounded anode plate and the energized cathode column. Since the cathode column is located inside the filter element, the filter element is in the high-voltage electrostatic field. At this time, the dust particles on its surface combine with the negative ions and discharge and deposit toward the anode plate, thereby completing the cleaning of the filter element to improve the filtering effect of the equipment.

[0008] Furthermore, a fixing plate is installed inside the filter cartridge, the filter element is installed inside the fixing plate, and the air inlet hole of the filter element is located above the fixing plate.

[0009] Furthermore, a pair of fixing grooves are provided at the bottom edge of the fixing plate, a first fixing hole connected to the fixing groove is provided at the top of the fixing plate, a pair of first fixing blocks are installed inside the filter cartridge, a first threaded hole is provided on the top of the first fixing block, a first screw is slid inside the first fixing hole, and the first screw and the first fixing hole are engaged and connected.

[0010] Furthermore, a pair of through holes are opened on the outside of the filter cartridge, and the pair of through holes are respectively connected to an air inlet pipe and an air outlet pipe, one end of the air inlet pipe and the air outlet pipe are connected to a flange, the air inlet pipe and the air outlet pipe are respectively located above and below the fixed plate, and a connecting hole is opened on one side of the anode plate, and the connecting hole is connected to one of the through holes.

[0013] The beneficial effect of adopting the above further scheme is that filtering the gas will remove moisture in the gas, and the moisture will gather at the inner bottom of the filter cartridge. When the water level exceeds the infrared transmitter, the infrared light generated by the infrared transmitter will not be accurately set on the infrared receiver due to refraction. The infrared receiver sends a signal to the controller because it does not receive the infrared light, and the controller then opens the solenoid valve for a period of time to allow the moisture to flow out.

[0014] Furthermore, a pair of second fixing blocks are installed on the side of the cylinder cover, a second fixing hole is opened on the top of the second fixing block, third fixing blocks are installed on both sides of the top of the filter cylinder, a second threaded hole is opened on the top of the third fixing block, a second screw is slid inside the second fixing hole, and the second screw is engaged with the second threaded hole.

[0017] The beneficial effect of adopting the above further scheme is that the bottom of the cylinder fixed in this way can be opened, so the cathode column can be closed regularly, so that the dust particles on the anode plate fall onto the bottom of the cylinder. At this time, the bottom of the cylinder can be taken out to clean the dust particles inside.

[0018] The beneficial effect of the utility model is as follows: the utility model obtains a self-cleaning air filter through the above design, uses a wire groove to connect the wires of the cathode column to the power supply, and grounds the wires of the anode plate. At this time, a high-voltage electrostatic field is formed between the grounded anode plate and the energized cathode column. Since the cathode column is located inside the filter element, the filter element is in the high-voltage electrostatic field. At this time, the dust particles on its surface combine with the negative ions and discharge and deposit toward the anode plate, thereby completing the cleaning of the filter element to improve the filtering effect of the equipment.

The wires of the cathode column 2002 are connected to the power supply by using the wire groove 1006, and the wires of the anode plate 2003 are grounded. At this time, a high-voltage electrostatic field is formed between the grounded anode plate 2003 and the energized cathode column 2002.
