[0027] The discharge chute 14 is in a "U" shape, and a silica gel plate 15 is fixedly installed on one side of the discharge chute 14.

[0028] Specifically, the top can be supported by the top plate 1, the two sides can be supported by the two side plates 11, the gauze on the surface can be driven to rotate by the gauze dewatering roller 13, and the sludge can be dewatered by the gauze, improving the practicability of the sludge dewatering device for ecological treatment.

[0029] On one side of the side plate 11, a filter 2 is fixedly installed. On the top of the filter 2, a connecting pipe 21 is fixedly installed. On the top of the connecting pipe 21, a water pump 22 is fixedly installed. On both sides of the water pump 22, two water outlet pipes 23 are fixedly installed. On one side of the water outlet pipe 23, a water outlet plate 24 is fixedly installed. On both sides of the water outlet plate 24, two water outlet nozzles 25 are fixedly installed.

[0030] Specifically, through the operation of the water pump 22, water can be pumped into the filter 2 for filtration and then sent into the water pump 22 through the connecting pipe 21. Through the two water outlet pipes 23, water can be sent into the water outlet plate 24, and through the two water outlet nozzles 25 on both sides of the water outlet plate 24, water can be sprayed out, so as to reverse flush the gauze dewatering roller 13.

[0031] Inside the top plate 1, three telescopic rods 3 are fixedly installed. At the bottom of the telescopic rod 3, a connecting plate 31 is fixedly installed. At the bottom of the connecting plate 31, a damping spring 32 is fixedly installed. On both sides of the bottom of the damping spring 32, two rotating grooves 33 are fixedly installed. At the bottom of the rotating groove 33, a squeezing roller 34 is fixedly installed. The outside of the squeezing roller 34 is movably connected with a silica gel belt 35.

[0032] Specifically, the height of the three squeezing rollers 34 can be adjusted by the telescopic movement of the telescopic rods 3. By wrapping the silica gel belt 35 around the outside of the three squeezing rollers 34, the dewatering effect of the squeezing rollers 34 can be improved. The squeezing rollers 34 and the silica gel belt 35 can be driven to rotate through the rotating grooves 33 to improve the dewatering effect, and the damping spring 32 can play a buffering role.

[0037] Working principle: First, place the sludge dewatering device for ecological treatment at the designated position. Feed the sludge from the inside of the feed hopper 12 above the gauze dewatering roller 13. Through the operation of the gauze dewatering roller 13, the gauze on the surface of the gauze dewatering roller 13 can be driven to rotate. Through the telescopic movement of the telescopic rod 3 inside the top plate 1, the connecting plate 31 can be pushed downward, thereby adjusting the height of the three extrusion rollers 34, making the silica gel belt 35 on the outside of the extrusion roller 34 present an inclined shape, so as to slowly extrude the sludge above the gauze dewatering roller 13, thereby improving the dewatering effect of the sludge. The extrusion roller 34 can be driven to rotate through the rotation groove 33, thereby driving the silica gel belt 35 to rotate, improving the practicability of the sludge dewatering device for ecological treatment. Through the rotation of the extrusion roller 34 and the silica gel belt 35, the sludge can be dewatered. Through the contraction of the two damping springs 32 at the bottom of the connecting plate 31, a buffering effect can be achieved to facilitate the extrusion and dewatering of sludge with different thicknesses. By attaching the silica gel plate 15 to one side of the gauze dewatering roller 13, the dewatered sludge can be scraped into the discharge chute 14 and sent out, improving the practicability of the sludge dewatering device for ecological treatment. The water filtered by the gauze is filtered through the filter screen 45 and then sent into the water storage tank 4 for storage. The water can be sent out through the opening and closing of the drain valve 41. Through the operation of the water pump 22, the water can be pumped out through the water pumping port 42, filtered by the filter 2, and finally sent into the water pump 22 through the connecting pipe 21, and then sent into the two water outlet plates 24 through the water outlet pipe 23. Sprayed out through the water outlet nozzles 25 on both sides and at the bottom of the water outlet plate 24, the gauze inside the gauze dewatering roller 13 can be reversely flushed. Through the simultaneous spraying of the six water outlet nozzles 25, the flushing effect on the gauze can be improved, and the practicability of the sludge dewatering device for ecological treatment is improved.
