[0018] The filter housing 1 supports and protects the components of the device from the outside. The sewage to be treated is put into the filter housing 1 through the water inlet 11. The filtered water in the filter housing 1 is discharged from the water outlet 12. The fixed plate 2 and the inner wall of the bottom end of the filter housing 1 clamp the upper ends of the rotating carrier plate 3. The fixed plate 2 blocks the upper part of the rotating carrier plate 3. The water discharge gap 21 lowers the sewage in the filter housing 1. After the sewage reaches the inside of the yield gap 31, the yield gap 31 uses the corresponding filter net 32 ​​to intercept impurities in the sewage.

At this time, the fixed plate 2 and the filter housing 1 clamp the rotating carrier plate 3, so that the sewage will not leak from between the fixed plate 2 and the filter housing 1. The filtered water is intercepted by the filter net 32 ​​and enters the water outlet 12 for discharge. When the used filter net 32 ​​needs to be refiltered, When cleaning and removing impurities, the rotating carrier plate 3 is controlled to rotate, and the rotating carrier plate 3 drives several filter screens 32 to rotate synchronously, so that the next filter screen 32 can rotate to between the water discharge gap 21 and the water outlet channel 12 to continue filtering work, thereby improving the effective working time of the device. After the rotating carrier plate 3 drives the used filter screen 32 to rotate to the corresponding position of the impurity removal gap 13, the output end of the telescopic push rod 33 is controlled to extend, and the telescopic push rod 33 pushes the U-shaped scraper 331, and the U-shaped scraper 331 pushes the impurities intercepted on the filter screen 32. The impurities are pushed and discharged from the outlet of the impurity removal gap 13, thereby cleaning the filter screen 32, so that the filter screen 32 can be cleaned for the next filtering work. In addition, the impurity removal gap 13 is in an open state, which is convenient for the staff to use tools and perform deep cleaning in the space of the gap 31 as needed. The operation is simple and convenient, and there is no need to open the filter bin body, thereby improving work efficiency.

[0019] A drainage trough 14 and a connecting groove 15 are provided in the filter housing 1. The drainage trough 14 corresponds to the position of the impurity discharge notch 13. The drainage trough 14 is connected to the internal space of the water outlet channel 12 through the connecting groove 15. A one-way valve 151 is installed on the inner wall of the connecting groove 15. When the clearance notch 31 and the filter screen 32 are rotated to the position of the impurity discharge notch 13, the drainage trough 14 is located below the filter screen 32, and the water carried by impurities in the space of the clearance notch 31 is precipitated and discharged into the drainage trough 14. The drainage trough 14 discharges the water into the connecting groove 15. The connecting groove 15 guides the water so that the water can be gathered into the water outlet channel 12 for unified discharge, and the one-way valve 151 can prevent the water source inside the one-way valve 151 from entering the connecting groove 15.

[0020] A driving motor 34 corresponding to the rotating carrier plate 3 is installed in the filter chamber body 1, and the output end of the driving motor 34 is fixedly connected to the bottom end of the rotating carrier plate 3; the driving motor 34 drives the rotating carrier plate 3 to rotate, and by setting program modules such as the movement time and rotation angle of the rotating carrier plate 3, the driving motor 34 can automatically complete the rotation driving work of the rotating carrier plate 3.
