The stainless steel brush 204 abuts against the inner wall of the filter cartridge 12 away from one end of the first connecting rod 203, which can clean the impurities in the inner wall of the filter cartridge 12 and the filter holes to prevent the impurities from accumulating on the inner wall of the filter cartridge 12, thereby reducing the filtering performance of the filter cartridge 12. A plurality of fan-shaped through holes are provided on the surface of the second connecting piece 205 to facilitate the sewage pump 7 to extract and discharge the sewage carrying impurities inside the filter cartridge 12. The brush plate 206 is arranged between the outer side of the filter cartridge 12 and the inner wall of the tank body 1, and a plurality of brush rollers arranged on one side of the brush plate 206 close to the filter cartridge 12 can clean the impurities adhered to the outer wall of the filter cartridge 12 to prevent them from accumulating on the outer wall of the filter cartridge 12, thereby affecting the filtering performance of the filter cartridge 12.

[0034] Further, see Figure 3 As shown, the top of the rotating shaft 2 is fixedly connected with a first connecting plate 201, and the end of the rotating shaft 2 away from the first connecting plate 201 is fixedly connected with a connecting column 207.

The diverter plates 301 can evenly distribute the water flow at the water inlet 101 to various parts of the filter to avoid the problem of uneven filtering effect caused by the water flow being concentrated in a certain part. By evenly distributing the water flow, the diverter plates 301 can ensure that all filter media can be fully utilized, thereby improving the filtering efficiency and more effectively removing suspended matter and impurities. The diverter plates 301 can help slow down the water flow speed and reduce the impact force of the water flow, thereby reducing the risk of impurity accumulation and clogging in the filter and extending the service life of the filter. The diverter plates 301 can stabilize the entry of water flow and prevent abnormal operation or failure of the filter due to unstable water flow.

[0036] Further, see Figure 1 and Figure 2 As shown, the surface of the tank body 1 is provided with a water outlet 102, the bottom of the tank body 1 is provided with a water inlet 101, and flanges are provided on one side of the water inlet 101 and the water outlet 102. The top of the top cover 103 is fixedly connected with a mounting frame 4, the top of the mounting frame 4 is fixedly installed with a transmission 5, one side of the transmission 5 is fixedly installed with a first motor 6, and the first motor 6 is transmission-connected to the rotating shaft 2 through the transmission 5.

The sewage pipe 9 and the sewage pump 7 are both arranged on the top of the filter tank body 1. Arranging the sewage pipe 9 above the tank body 1 can ensure that the dirt will not be directly deposited at the bottom of the filter tank body 1 or the water inlet 101 when discharged, so as to avoid clogging the filter tank body 1 and maintain the normal operation of the filter tank body 1. The sewage pipe 9 is arranged above the tank body 1 to ensure that the sewage is subjected to the effect of gravity when discharged, thereby improving the discharge efficiency, ensuring that the sewage can be discharged in a timely and effective manner, and will not stay in the filter tank body 1 for too long. The sewage pipe 9 is arranged above the tank body 1 to make the sewage outlet 10 easier to operate and maintain, reduce the work intensity of the maintenance personnel, and improve the maintenance efficiency. The second motor 8 is fixedly installed on the top of the sewage pump 7, and the sewage outlet 10 is arranged on the side of the sewage pump 7 away from the sewage pipe 9. A pressure difference switch 11 is arranged below the water outlet 102, and the top and bottom of the pressure difference switch 11 are respectively connected to the water inlet 101 and the water outlet 102 through the detection tube. The flanges arranged at the water inlet 101 and the water outlet 102 facilitate the connection of the water inlet pipe and the water outlet pipe with the filter, and can improve the air tightness of the filter to avoid the infiltration of dangerous substances. The surface of the filter tank body 1 can be coated with an explosion-proof coating. This explosion-proof coating can effectively isolate high-temperature surfaces and reduce the risk of fire or explosion. The explosion-proof coating can be used for a long time in harsh environments.

[0037] Working principle and implementation method: Before use, the explosion-proof self-cleaning filter can be connected to the water inlet pipe by using the flange set on one side of the water inlet 101, and connected to the water outlet pipe by using the flange set on one side of the water outlet 102. Similarly, the sewage outlet 10 is also connected to the sewage pipe 9 like the water inlet 101 and the water outlet 102. The tank body 1 to be filtered is connected to the water inlet pipe, the water outlet pipe and the sewage pipe 9 respectively, and the sewage can enter the tank body 1 from the water inlet pipe. The diverter plate 301 of the water inlet 101 can evenly distribute the water flow at the water inlet 101 to various parts of the filter, avoiding the problem of uneven filtering effect caused by the concentration of water flow in a certain part, and also reducing the impact force of the water flow, thereby reducing the risk of accumulation and clogging of impurities in the filter and extending the service life of the filter. Then, the first motor 6 is started to control the rotation of the shaft 2. The first connecting plate 202 fixedly connected to the surface of the shaft 2 will stir the sewage inside the filter cartridge 12, so that the impurities inside the sewage can be quickly intercepted by the filter cartridge 12 and remain inside the filter cartridge 12. At the same time, the shaft 2 will also drive the stainless steel brush 204 and the brush plate 206 to rotate to prevent impurities from adhering to the inner and outer walls of the filter cartridge 12, thereby affecting the filtering performance of the filter cartridge 12. Then, the filtered sewage will be discharged from the water outlet 102 and sent to the purification device for treatment, and the sewage carrying impurities inside the filter cartridge 12 will be extracted by the sewage pump 7 and sent to other devices for re-filtration treatment.
