Through the cooperation of the first sludge dewatering component 41 and the mixing barrel 22, the sludge after preliminary treatment can be crushed. The two ends of the outer wall of the first rotating drum 411 are rotatably connected to the interior of the retaining ring 34. A fixing ring 132 is installed at the left end of the inner wall of the first rotating drum 411. Through the movement of the fixing ring 132, the first rotating drum 411 can be driven to perform telescopic movement.

Through the cooperation of the mixing barrel 22 and the capstan 413, the collected and gathered sludge can be crushed. The first rotating drum 411 is provided with a spiral sheet 414 on its inner wall, and the pre-treated sludge is first discharged into the first rotating drum 411 through the sludge input pipe 122, and then the second sludge dewatering assembly 43 drives the limiting assembly 42 and the first rotating drum 411 to rotate, so that the spiral sheet 414 squeezes and dehydrates the pre-treated sludge, and the dehydrated liquid is filtered out to the inside of the collecting drum 33 through the first filter screen 412. The first sludge dewatering assembly 41 is internally slidably connected to the limiting assembly 42, and the sludge can be dehydrated once through the cooperation of the first sludge dewatering assembly 41 and the limiting assembly 42.

The convex block at the left end of the outer wall of the first limiting ring 424 contacts the limiting groove 133. The convex block at the left end of the outer wall of the first limiting ring 424 is inserted into the limiting groove 133 through the push of the hydraulic rod 123, so that the second rotating drum 421 can drive the first rotating drum 411 to rotate. The inner part of the limiting assembly 42 is slidably connected with the second sludge dewatering assembly 43, and the right end of the second sludge dewatering assembly 43 is connected to the polygonal groove block 24. The second sludge dewatering assembly 43 can be driven by the drive motor 23 to perform secondary dehydration operation.The overlapping screw rod 431 is slidably connected inside the second rotating cylinder 421. A second limiting ring 432 is provided at the left end of the outer wall of the overlapping screw rod 431. The second limiting ring 432 is slidably connected inside the movable groove 423. The convex block at the left end of the outer wall of the second limiting ring 432 contacts the inner wall of the movable groove 423. By rotating the overlapping screw rod 431, the second rotating cylinder 421 can be driven to rotate. A polygonal block 433 is provided at the right port of the overlapping screw rod 431. The polygonal block 433 and the polygonal groove block 24 are connected inside the polygonal groove block 24. By driving the driving motor 23, the overlapping screw rod 431 can be driven to rotate inside the second rotating cylinder 421, so that the overlapping screw rod 431 performs secondary extrusion dehydration on the sludge.,

[0056] In specific use, those skilled in the art will start the driving motor 23 to drive the stacked screw 431 to rotate. When the sludge is pretreated through the metering tank and the flocculation mixing tank, the output end of the flocculation mixing tank transports the sludge into the interior of the sludge input pipe 122, and then the sludge input pipe 122 transports the sludge between the first rotating cylinder 411 and the second rotating cylinder 421. At this time, by starting the hydraulic rod 123, the hydraulic rod 123 drives the sludge input pipe 122 to move to the right end until the sludge input pipe 122 is inserted into the interior of the second rotating cylinder 421. Thus, the first limiting ring 424 is inserted into the limiting groove 133 at the right end of the fixed ring 132, and the second limiting ring 432 is inserted into the left end of the inner wall of the movable groove 423. The stacked screw 431 and the second rotating cylinder 421 move to the left end accordingly. At this time, the stacked screw 431 can drive the second rotating cylinder 421 and the first rotating cylinder 411 to rotate, so that the sludge falling between the first rotating cylinder 411 and the second rotating cylinder 421 is squeezed by the sludge input pipe 122 and then enters the interior of the stacked screw blades 414 for spiral extrusion and transportation. By repeating the above operations, until the metered sludge is spirally transported to the interior of the mixing cylinder 22 through the stacked screw blades 414. During the spiral transportation process of the stacked screw blades 414, through the extrusion of the stacked screw blades 414, the squeezed liquid can be introduced into the interior of the collection cylinder 33 through the first filter screen 412 and then discharged by the drainage box 35. The sludge entering the interior of the mixing cylinder 22 is continuously crushed by the winch 413 at the right end of the first rotating cylinder 411, so that impurities such as fibers and hairs inside the sludge are broken and fully mixed with the sludge. When the sludge is to be discharged, by starting the hydraulic rod 123 again, the sludge input pipe 122 moves to the left, driving the first rotating cylinder 411 and the second rotating cylinder 421 to return to the initial position. At this time, the right end of the stacked screw 431 contacts the sludge inside the mixing cylinder 22, and through the continuous rotation of the stacked screw 431, the sludge is continuously spirally transported and squeezed from right to left. The squeezed liquid falls into the interior of the collection cylinder 33 through the second filter screen 422 and the first filter screen 412 for discharge, while the sludge is transported to the gap between the movable ring 131 and the fixed ring 132 by the stacked screw 431 and then discharged to the ground through the sludge discharge port 114 at the lower end of the sludge discharge cylinder 112, thus completing the secondary dehydration operation.
