[0032] Working principle: When in use, when sewage enters the L-shaped filter box 100 through the water inlet pipe 108, the two filter belts 103 in the L-shaped filter box 100 filter the impurities and soil in the sewage in turn, and the filtered impurities and soil are respectively blocked on the outside of the corresponding filter belts 103, and the two first motors 101 are turned on at the same time. The output shaft of the first motor 101 drives the right transmission roller 102 to rotate, and the right transmission roller 102 drives the left transmission roller 102 to rotate through the filter belt 103. The two transmission rollers 102 rotate at the same time and drive the filter belt 103. The filter belt 103 in transmission can transport the soil and impurities to the left. When the soil and impurities are driven downward, they fall into the corresponding collection box 107 under the action of gravity;

[0033] When the eccentric wheel 8 rotates for the second half circle, the ball bearings 13 are squeezed, and the squeezing force drives the circular frame 6 to move upward through the ball bearings 13, and the circular frame 6 compresses the spring 10 upward. When the eccentric wheel 8 rotates for the second half circle, the squeezing force on the ball bearings 13 is released. At this time, the elastic force of the spring 10 in the compressed state drives the circular frame 6 to move downward, and the eccentric wheel 8 continues to rotate, thereby making the circular frame 6 move up and down in a cycle, and the circular frame 6 drives the two U-shaped rods 5 to move up and down in a cycle, and the U-shaped rod 5 drives the two knocking rollers 4 to move up and down in a cycle. During the upward movement of the knocking roller 4, the filter belt 103 is knocked and vibrated inside the corresponding filter belt 103, and the filter belt 103 is vibrated under the knocking force. Under the vibration force, the impurities or mud attached to the filter belt 103 can be effectively shaken off;

[0034] At the same time, the air pump 16 extracts the external gas, and the extracted gas is sequentially introduced into the two horizontal pipes 3 through the wind collecting hood, the vertical pipe 15 and the two connecting pipes 14. The gas inside the horizontal pipe 3 is blown out through the corresponding multiple blowing pipe heads 9 to blow the inner bottom of the filter belt 103. Under the blowing of the gas, the attached impurities and soil can be further blown down into the collection box 107. In the process of discharging impurities and soil, the force of knocking and vibration is combined with the force of gas blowing, which can effectively vibrate and blow the impurities and soil attached to the filter belt 103 into the collection box 107, reducing the adhesion of impurities and soil, achieving the effect of auxiliary discharge, and no need for personnel to clean up separately later, thereby improving the stability of automatic slag discharge;

[0035] The treatment agent is added through the feeding valve, and the drive motor 106 is turned on at the same time. The output shaft of the drive motor 106 drives the multiple stirring blades to rotate through the stirring rod 105, effectively mixing the filtered sewage and the treatment agent to achieve the effect of sewage treatment.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
