[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it. Sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering.

[0003] Application No. CN202121060525.6 discloses a sludge discharging device for sewage treatment, which includes a sedimentation tank, a sludge pressing plate installed inside for squeezing sludge, and a belt installed on the inner side of the bottom. The sedimentation tank includes: support columns installed at the bottom; a drainage port opened on the left side; a sludge discharge groove arranged on the right side, and connecting pins installed on the side wall. This sludge discharging device for sewage treatment is provided with a sludge pressing plate. After the sewage sedimentation is completed, the upper clear liquid is discharged from the drainage port, while the sludge accumulates at the bottom of the sedimentation tank. By driving the connecting rod to rotate through a turning handle, the sludge pressing plate moves downward to squeeze the sludge, compressing it and squeezing out the residual water for subsequent treatment; a belt is arranged at the bottom of the sedimentation tank, and the motor drives the transmission wheel and the belt to move. The scraper fixed on the belt pushes the compacted sludge into the sludge discharge groove on the right side during the movement, and then the sludge is discharged by pulling out the connecting rod and the sludge discharge plate outward through a handle.

[0004] However, there are still the following problems: The work of the sludge pressing plate needs to bear a large pressure. When treating a large amount of sludge, with the continuous progress of mechanical actions, problems such as damage to the sludge pressing plate or deviation of the pressing angle may occur, which is likely to have an adverse impact. Content of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 3 , the embodiment provided by the present invention:

[0021] It includes a processing tank 1 and a hydraulic cylinder 7. An output pipeline 2 is provided at the top of the processing tank 1. A first connection pipeline 3 is installed at the lower part of one side of the processing tank 1. A second connection pipeline 4 is installed on the upper surface of the other side of the processing tank 1. The hydraulic cylinder 7 passes through the bottom of the processing tank 1 through the hydraulic rod 8 in cooperation with a linear bearing, and the end of the hydraulic rod 8 is fixedly connected to the chassis 9. A compression resistance mechanism 11 is provided on the surface of the chassis 9, and the chassis 9 is connected to the mud pressing plate 10 through the compression resistance mechanism 11.

[0022] The compression resistance mechanism 11 includes a damping rod 22, a mounting block 12, a spring sleeve 13, a connecting block 15, a moving seat 16 and a fixed seat 19. One end of the damping rod 22 is fixed on the surface of the chassis 9, and the other end of the damping rod 22 is fixedly connected to the surface of the mud pressing plate 10. The surface of the damping rod 22 is movably sleeved with a mounting block 12. First mounting edges 14 are integrally formed on both sides of the mounting block 12. A second mounting edge 17 is integrally formed on one side surface of the moving seat 16. Both ends of the connecting block 15 are respectively movably connected to the first mounting edge 14 and the second mounting edge 17 through a connecting shaft. A spring sleeve 13 is sleeved on the surface of the damping rod 22, and both ends of the spring sleeve 13 are respectively in contact with the surface of the chassis 9 and the surface of the mounting block 12.

[0023] A chassis 9 is installed on the inner wall of the bottom of the processing tank 1. The edge surface of the chassis 9 is in contact with the inner wall of the processing tank 1, and a waterproof strip is bonded at the edge of the chassis 9. The chassis 9 structure is set to increase the overall resistance of the processing tank 1, and at the same time provide support for the compression resistance mechanism 11 to increase its compression and impact resistance effect, and avoid the overall structure from being easily damaged due to external bumps.

[0024] Three brackets 5 are successively and evenly welded to the bottom of the processing tank 1. A mounting seat 6 is welded to the surface between the three brackets 5. The mounting seat 6 is bolted and fixed to the bottom surface of the hydraulic cylinder 7.

A convex edge 21 is integrally formed in the central part of the guide rod 20. The pressure-resistant mechanism 11 is provided to ensure the safety when the hydraulic rod 8 performs the pushing action. When the hydraulic rod 8 pushes the chassis 9 to rise, the damping rod 22 part can be used to support the mud pressing plate 10. During the whole action, the damping rod 22 is compressed and deformed, and this drives the two connecting blocks 15 on both sides to also move downward, and then pushes the two moving seats 16 to move along the guide rod 20, so as to achieve a certain auxiliary support and guiding effect, ensure the uniform dispersion of pressure, and avoid damage to the structure of the mud pressing plate 10 due to excessive pressure or continuous uneven force during continuous operation.
