The telescopic rod 232 is started, and the telescopic rod 232 drives the movable plate 233 to move upward, and the movable plate 233 drives the sludge to move upward. Since the movable plate 233 is inclined, the sludge tends to slide outward under the influence of gravity, which is more conducive to the workers to clean the sludge.

[0031] Working principle:

[0032] When in use, flocculants and magnetic powder are put into the tank body 1, impurities in the sewage are magnetically precipitated to form flocs, which fall downward and accumulate on the surface of the bottom platform 4. The scraper device 3 sends the accumulated sludge into the dredging device 2, and then the dredging device 2 sends the sludge to an external container;

[0033] When in use, the motor 31 drives the threaded rod 32 to rotate, and the threaded rod 32 drives the sliding block 331 to move, and the sliding block 331 drives the scraper plate 332 to move, and the scraper plate 332 moves forward along the base 4, and the scraper plate 332 scrapes the sludge on the base 4, and the scraper plate 332 drives the sludge to move to the inside of the collecting assembly 23. When the scraper plate 332 moves to an uneven position on the base 4, the scraper plate 332 is forced to rotate upward, and the scraper plate 332 drives the arc plate 333 to slide, and the arc plate 333 slides along the inside of the sliding block 331, and the arc plate 333 drives the rebound spring 334 to compress.

The bottom of the scraper plate 332 is tightly attached to the base 4, and the scraper assembly 33 can adapt to the uneven pool bottom;

[0034] While scraping the mud, the sliding block 331 drives the fixed plate 341 to move, and the fixed plate 341 drives the guide plate 342 and the collection bin 343 to move forward. Since the base 4 is inclined, the guide plate 342 moves obliquely downward relative to the water surface. The guide plate 342 moves forward, pushing the floating objects on the water surface to move forward. At this time, the floating objects are attached to the intersection of the guide plate 342 and the horizontal plane. As the height of the guide plate 342 continues to decrease, the intersection of the guide plate 342 and the horizontal plane gradually approaches the collection bin 343, and the floating objects approach the collection bin 343 along the guide plate 342. When the top of the guide plate 342 moves below the horizontal plane, the floating objects move to the inside of the collection bin 343. In this way, the workers only need to clean up the floating objects in the collection bin 343, and the cleaning component 34 effectively reduces the labor intensity of the workers.

[0035] When dredging is needed, the winder 21 is started, and the winder 21 drives the steel cable 22 to move. The steel cable 22 is wound around the outside of the winder 21, and the steel cable 22 drives the collecting bin 231 to move upward. The collecting bin 231 moves above the water surface, and the collecting bin 231 drives the sludge to move upward. By adjusting the winder 21, the height of the collecting bin 231 is adjusted so that the collecting bin 231 can adapt to the height of the workers, and the telescopic rod 232 is started, and the telescopic rod 232 drives the movable plate 233 to move upward. The movable plate 233 drives the sludge to move upward, and the workers clean up the sludge on the movable plate 233.
