[0025] In the process of working, open the pipe plug 208 at the top end of the water suction pipe 207 outside the water storage tank 205 near the bottom corner, inject water into the water storage tank 205 through the water suction pipe 207 until the appropriate water level is reached, and then tightly plug the pipe plug 208 to prevent impurities from entering and water from overflowing. Start the water suction pump 202 outside the water inlet pipe 201, and the water in the water storage tank 205 is sucked into the water inlet pipe 201 under the action of the water suction pump 202. The water suction pump 202 pressurizes the water, and the pressurized water flows through the water inlet pipe 201 to the circular high-pressure nozzle 206 at the end. The circular high-pressure nozzle 206 sprays water in the form of high-pressure jet to the filter material in the cleaning tank 1. The high-pressure water flow impacts the surface and shallow layer of the filter material, washing away dust, loose microorganisms and other dirt, and penetrating into the pores of the filter material, carrying away part of the internal dirt.

According to the accumulation height of the filter material and the depth of the cleaning required, the length of the telescopic rotating shaft 302 can be adjusted to make the flexible brush 303 penetrate into the interior of the filter material. The flexible brush 303 fully contacts the filter material particles during rotation, loosens and scatters the deep-layer dirt in the filter material, such as sticky microbial metabolites and chemical precipitates, and reduces the adhesion between the dirt and the filter material. During the cleaning process, high-pressure water washing and stirring cleaning cooperate with each other. The loosened dirt is washed away by the high-pressure water flow in time to avoid reattachment to the filter material, thereby realizing comprehensive and thorough cleaning of the filter material. At the same time, the multiple groups of linearly installed vibrators 108 outside the cleaning tank 1 work, and the generated vibration is transmitted to the filter material in the cleaning tank 1, further promoting the dirt to fall off from the filter material, improving the cleaning efficiency. The sewage generated during the cleaning process accumulates in the cleaning tank 1. When a certain amount is reached, open the drain valve 112 inside the cleaning tank 1, and the sewage is discharged from the cleaning tank 1 through the drain pipe 107 connected to the drain valve 112 at the bottom of the cleaning tank 1. The dirt washed and stirred by gravity first falls on the discharge tray 104 installed from top to bottom on one side of the cleaning tank 1. The drain screen 109 installed through the bottom of the discharge tray 104 allows sewage to pass through and retains larger particles of dirt. The sewage and smaller particles of dirt filtered by the drain screen 109 continue to flow downward into the dirt tank 105. The dirt tank 105 further retains dirt at the bottom of the dirt tank 105, allowing the sewage to be discharged. In this way, the dirt is collected in layers.

[0026] Through the above steps, the water inlet pipe 201 serves as a channel connecting the water storage tank 205 and the circular high-pressure spray head 206, and the externally installed water pump 202 is the power source for the water flow in the water inlet pipe 201. After the water pump 202 is started, negative pressure is formed in the water inlet pipe 201, the water in the water storage tank 205 is pumped into the water inlet pipe 201, and the water is pressurized through the working principle of the water pump 202, so that the water can be smoothly transported in the pipeline and obtain sufficient pressure, preparing for the subsequent high-pressure injection. The circular high-pressure spray head 206 is installed at one end of the water inlet pipe 201, and its special circular structure and internal design can convert the water pressurized by the water pump 202 into a high-speed and high-pressure jet. When the jet is sprayed onto the filter material, the powerful impact force can effectively impact the surface and shallow layer of the filter material, and the filter material is washed away. At the same time, part of the high-pressure water flow can also penetrate into the pores of the filter material, carrying away some dirt, achieving the cleaning of the filter material.
