Therefore, they will not be described here.

[0029] In this embodiment, the motor 608 is fixedly installed on the base 609 fixedly installed on the front side wall of the U-shaped frame 604, which facilitates the stable installation of the motor 608.

[0030] In this embodiment, the width of the grid-shaped filter hopper 607 is smaller than the inner width of the sewage treatment tank 1, which can ensure that the grid-shaped filter hopper 607 can drop into the sewage treatment tank 1.

[0031] In this embodiment, the bottom of the connecting beam 606 is fixedly installed with an assembly plate 610, which is fixedly installed on the top of the grid-shaped filter hopper 607 through bolts, facilitating the disassembly and assembly of the grid-shaped filter hopper 607 for maintenance and cleaning.

[0032] In this embodiment, a plurality of uniformly distributed reinforcing ribs 611 are fixedly installed on the inner right side of the mesh filter 607. The two ends of the reinforcing ribs 611 are fixedly connected to the inner front and inner rear sides of the mesh filter 607, respectively, thereby enhancing the structural strength of the mesh filter 607.

[0033] Based on the above structure, the working principle of the high-efficiency suspended solids filtration wastewater treatment device provided in this application is as follows:

[0034] During wastewater treatment, when it is necessary to filter suspended solids in the wastewater, the process begins as follows: First, the electric slide 602 slides to the left on the electric guide rail 601, moving the mesh filter 607 to a suitable starting filtration position on the right. Then, the hydraulic cylinder 603 extends, driving the U-shaped frame 604 to descend, immersing the mesh filter 607 in the wastewater to a suitable depth. Next, the motor 608 rotates clockwise, driving the rotating shaft 605 to rotate, which in turn drives the mesh filter 607 to rotate clockwise via the connecting beam 606 (e.g., ...). Figure 1 (As shown from the perspective of the viewpoint), after rotating the mesh filter bucket 607 to a suitable angle, stop the motor 608. Then, control the electric slide 602 to slide to the left on the electric guide rail 601, which will control the mesh filter bucket 607 to move to the left. The mesh filter bucket 607 can intercept and filter suspended solids in the sewage, so that the suspended solids are retained in the mesh filter bucket 607. When the mesh filter bucket 607 moves to the leftmost side inside the sewage treatment tank 1, stop the electric slide 602 from sliding, and then control the hydraulic cylinder 603 to retract and reset, which will control the mesh filter bucket 607 to rise back to the top of the sewage treatment tank 1. At this time, the suspended solids are still in the mesh filter bucket 607.

[0035] Next, continue to control the electric slide 602 to slide to the left on the electric guide rail 601, so that when the mesh filter bucket 607 moves to a suitable position on the left side of the sewage treatment tank 1, stop the electric slide 602 from sliding, and then control the motor 608 to reverse and drive the rotating shaft 605 to rotate, which in turn drives the mesh filter bucket 607 to rotate counterclockwise through the connecting beam 606 (e.g. Figure 1 As shown from the perspective of the screen, as the mesh filter bucket 607 rotates counterclockwise at an increasingly larger angle, the suspended solids in the mesh filter bucket 607 can fall out (at this time, the filtered suspended solids fall to the left side of the sewage treatment tank 1). When the mesh filter bucket 607 rotates counterclockwise to contact the vibration guide plate 705, the motor 608 stops running.

[0036] Then, the vibration motor 704 is started to generate vibration force, and the two springs 707 play a role in buffering and assisting vibration transmission, so that the vibration effect is more uniform and stable. The vibration force is transmitted to the grid-shaped filter hopper 607 through the vibration guide plate 705, so that the suspended solids adhering to the inner wall of the grid-shaped filter hopper 607 are shaken off, thereby avoiding the filter holes of the grid-shaped filter hopper 607 from being blocked due to the accumulation of suspended solids. After the shaking-off operation is completed, the vibration motor 704 is stopped, and the next time the suspended solids in the sewage treatment tank 1 are efficiently filtered according to the above operation steps.
