The hydraulic telescopic column 200 is located at the top of the outer wall of the movable base plate 110 and on one side of the outer tank 100. The inner tank 300 is located inside the hydraulic telescopic column 200. A bottom fixing block 350 for dewatering is fixed to the bottom of the inner wall of the inner tank 300. A filter cloth 360 for dewatering is fitted inside the inner tank 300. The filter cloth 360 can be fitted onto the inner wall of the inner tank 300, and personnel can pump the sludge to be dewatered into the filter cloth 360 using a water pump. The water in the sludge can be squeezed out by pressing, while the sludge remains inside the filter cloth 360. Mesh frames 320 are provided on the outer side of the inner tank 300. Reinforcing ribs are fixed to the outer wall of the inner tank 300 and outside the mesh frames 320. The mesh frames 320 serve to guide the separated wastewater into the outer tank 100. An outer extension ring 310 is fixed above the outer side of the inner tank 300. The bottom of the outer wall of the outer extension ring 310 is rotatably connected to the top of the outer wall of the outer tank 100. The outer extension ring 310 is designed to overlap the outer wall of the outer tank 100. A rotating ring 311 is fixed to the bottom of the outer wall. The top of the outer wall of the outer tank 100 is slidably connected to the rotating ring 311 via an annular groove. A rotary motor 330 is installed at the bottom of the outer wall of the movable base plate 110, directly below the outer tank 100. The outer wall of the rotary motor 330 is fixedly connected to the bottom of the outer wall of the movable base plate 110 via a fixed frame. The rotary motor 330 is mainly used to drive the inner tank 300 to rotate during the dewatering process, so that the inner tank 300 can use centrifugal force to accelerate the sludge dewatering efficiency during rotation. The top output shaft of the rotary motor 330 passes through the movable base plate 110. 10 is fixedly connected to the bottom of the outer wall of the outer tank 100. A drain pipe 340 is fixedly connected to the bottom of the outer wall of the outer tank 100 on the side away from the hydraulic telescopic column 200. A valve is fixed on the drain pipe 340. Supporting rotating rods 331 are fixed to the bottom of the outer wall of the inner tank 300. Multiple supporting rotating rods 331 are evenly arranged in a ring array. Ball bearings are provided at the bottom of the outer wall of the supporting rotating rods 331. The supporting rotating rods 331 are provided to support the bottom of the inner tank 300 without affecting the rotation of the inner tank 300, so as to ensure the stability of the inner tank 300 when placed inside the outer tank 100.

[0026] An upper movable pressure block 230 is provided above the inner wall of the inner tank 300. The bottom of the outer wall of the hydraulic telescopic column 200 is fixedly connected to one side of the top of the outer wall of the movable base plate 110. A hydraulic cylinder is provided at the top of the outer wall of the movable base plate 110 and on one side of the hydraulic telescopic column 200.

The hydraulic telescopic column 200 can drive the crossbeam 210 to move up and down through the output shaft. When the crossbeam 210 moves, it can drive the upper movable pressure block 230 to move through the connecting rod 220. The upper movable pressure block 230 can press the sludge from the top. Together with the upper fixed pressure block 350, the sludge can be quickly dewatered.

[0027] The usage process of this utility model is as follows: Those skilled in the art can assemble the device according to the above description, then connect all electrical equipment to an external power supply and connect a controller for easy operation. Personnel can move the device to a suitable position using the casters 120. Then, the filter cloth 360 can be laid flat inside the inner tank 300. Next, the sludge to be dewatered can be poured into the filter cloth 360. After completion, the upper end of the filter cloth 360 can be placed inside the inner tank 300, covering the upper end of the sludge. Then, the personnel can control the hydraulic telescopic column 200 to retract, causing the upper moving pressure block 230 to extend into the inner tank 300. The filter cloth 360 applies downward pressure to the sludge from the bottom, causing the sludge inside to dewater. The water in the sludge is discharged into the outer tank 100 through the mesh frame 320 and then discharged through the drain pipe 340. After the pressure is applied, the rotary motor 330 drives the inner tank 300 to rotate. The centrifugal force generated by the rotation of the inner tank 300 can accelerate the sludge dewatering rate. After dewatering is completed, the operator can control the hydraulic telescopic column 200 to extend, causing the upper moving pressure block 230 to move upward and reset. Then, the operator can pull the upper moving pressure block 230 out of the inner tank 300 to remove the dewatered sludge and put it back in place.

[0028] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
