When the installation frame 11 is in the initial position, one of the filter screens 12 is located in the filtering area, and the other is located in the cleaning area. The sucked sewage and impurities are intercepted by the filter screen in the filtering area to prevent the subsequent pipeline from being blocked. The filter screen in the cleaning area is in a standby cleaning state. When the filter screen is blocked and the flow rate of the spray pipe 8 decreases, the filter screen cleaning process can be started, the first hand valve (for example, the left guide pipe) of one of the guide pipes 19 is opened, the high-pressure water in the annular pipe 6 enters the corresponding second chamber through the guide pipe 19, and the high-pressure water flows into the first chamber through the water flow hole 24 after entering the second chamber, pushing the moving plate 18 to slide in the opposite direction (for example, moving to the right), and driving the installation frame 11 and the first filter screen 12 to move synchronously.

When the installation frame 11 moves to the maximum stroke, the first filter screen 12 originally located in the cleaning area is completely exposed in the cleaning area, and the cleaning pipe 27 outlet is opened. At this time, the high-pressure water is sprayed out from the annular pipe 6 through the cleaning pipe 27 to perform backflushing cleaning on the filter screen, and the intercepted impurities are flushed down. At the same time, the third hand valve of the corresponding sewage discharge pipe 25 in the cleaning area is opened, and the backflushed impurities are discharged out of the shell 3 through the sewage discharge pipe 25 under the guidance of the guide cover 26. After the cleaning is completed, the first hand valve of the sewage discharge pipe 25 is closed first, and then the first hand valve of the guide pipe 19 is closed. If the other side filter screen needs to be cleaned, the second hand valve of the other side guide pipe 19 is opened, the accumulated water in the corresponding first chamber and second chamber is discharged, and the first hand valve of the other side guide pipe 19 is opened.
