Furthermore, the filter box includes a shell and a sealing plate, the sealing plate is connected to the shell by bolts, the upper and lower side walls of the shell are provided with sliding grooves, and the upper and lower ends of the filter plate are arranged in the sliding grooves.

When the impurities on the surface of the filter plate are difficult to remove by the brush plate after long-term use, the sealing plate can be opened and the filter plate can be pulled out for manual cleaning.

Furthermore, a second motor is installed on the outer surface of the sealing plate, and the output shaft of the second motor passes through the interior of the shell. The output shaft of the second motor is connected to a connecting shaft, which is arranged on the side of the filter plate facing away from the brush plate. A plurality of connecting ropes are connected to the outer surface of the connecting shaft, and steel balls are installed at the ends of the connecting ropes.

When the second motor is started, it drives the connecting shaft to rotate, and through the action of centrifugal force, drives the steel balls to rotate and hit the side of the filter plate facing away from the brush plate. Therefore, while the lifting mechanism is cleaning the filter plate, it can hit the other side of the filter plate to shake off impurities on the surface of the filter plate, thereby improving the cleaning effect.

Furthermore, a sewage pipe is connected to the bottom of the shell, and a valve is arranged on the sewage pipe.

When the filtered sewage inside the water storage tank backwashes the filter plate, the valve on the sewage pipe can be opened to discharge the backwash sewage.

Furthermore, the connecting rope and the steel balls are both made of stainless steel.

Stainless steel has excellent corrosion resistance and can maintain good performance in sewage for a long time, ensuring the use effect.
