[0028] Working principle: A connecting pipe 214 is installed on one side of the filter 1. During use, the connecting pipe 214 is first connected to an external pipe, allowing the cleaning solution to enter the filter 1. When the filter element 3 needs cleaning, the first nut 104 is rotated. A discharge port 103 is located at the bottom of the filter 1 and engages with the first nut 104. Rotating the first nut 104 opens the discharge port 103, ensuring impurities are removed. Once the discharge port 103 is open, the filter fluid can be discharged. The connecting pipe 214 conveys the cleaning fluid. A guide plate 202 is installed on one side of the connecting pipe 214, and multiple backwash columns 201 are installed on the top of the guide plate 202. Because the backwash columns 201, guide plate 202, and connecting pipe 214 are interconnected, when the cleaning fluid enters the connecting pipe 214, it will also enter the backwash columns 201. Two nozzles 203 are opened on the top of the backwash columns 201, so that the cleaning fluid will be sprayed out from the nozzles 203 as it is conveyed. The filter element 3 is sleeved on the surface of the backwash column 201, and the filter element 3 is close to the nozzles 203. An impeller 305 is also installed inside one side. Because the nozzle 203 and the impeller 305 are fitted together, when the cleaning fluid is sprayed from the nozzle 203, the impeller 305 can drive the filter element 3 to rotate. A cleaning roller 301 is also installed inside the filter 1 on the side near the filter element 3, and the cleaning roller 301 is fitted with the filter element 3. Therefore, when the filter element 3 rotates, the cleaning roller 301 can clean the filter element 3. Multiple backwash pipes 204 are also provided on the surface of the backwash column 201, and backwash plugs 205 are installed inside each of the multiple backwash pipes 204. The backwash plug 205 is connected to the backwash tube 204 via a spring 210. As the cleaning fluid is continuously supplied, it will squeeze the backwash plug 205, causing it to move. Multiple spray holes 206 are provided at the end of the backwash plug 205. When the backwash plug 205 moves, the cleaning fluid can be sprayed out from the spray holes 206, thereby achieving the purpose of cleaning the filter element 3 from the inside. An impurity outlet 215 is provided at the bottom of the separator plate 2, and the impurity outlet 215 is matched with the impurity discharge port 103, so that the impurities after cleaning can be discharged from the impurity discharge port 103.
