When the sludge enters, it will first contact the small brush bristles 19, and then the internal fiber cloth will contact the small brush bristles 19 and be intercepted when it moves downward. At this time, the processing rod can be... 14 Connect to the power supply to make it rotate. When rotating, the small brush bristles 19 will agitate the fibrous cloth inside the sludge, causing it to wrap around itself. After agitation and wrapping, the sludge can be discharged through the discharge port 11 into the collection box 101. At this time, the locking block 18 can be pressed to enter the spring telescopic rod 17. Then, the impurity removal rod 16 can be slid out of the processing rod 14. After removing the impurity removal rod 16, the fibrous cloth wrapped on the small brush bristles 19 can be processed. Then, the impurity removal rod 16 can be installed back into the processing rod 14. By adding small bristles 19, the sludge can be wrapped around the fiber cloth after entering, thereby quickly gathering the fiber cloth. Then, the cleaning rod 16 and the treatment rod 14 are connected through the mounting groove 15. When cleaning the small bristles 19, the small bristles 19 can be quickly disassembled by pressing the locking block 18, which makes cleaning the small bristles 19 more convenient. At the same time, when the cleaning rod 16 is installed, it will contact the inclined surface of the locking block 18. When pushing it during installation, it can be guided to fall quickly into the mounting groove 15, thus enabling quick installation.
[0026] like Figures 1 to 3 As shown, the inner wall of the impurity removal tank 1 is fixed with multiple connecting pipes 21; one end of the connecting pipe 21 is connected to a rinsing nozzle 2; the other end of the connecting pipe 21 is connected to a transmission pipe 22; the bottom of the transmission pipe 22 is connected to a water guide pipe 23; during operation, when the small brush bristles 19 are entangled in sludge, the water guide pipe 23 can be connected to a water pump, and the water source first flows into the transmission pipe 22 through the water guide pipe 23, and then is sent into the rinsing nozzle 2 through the connecting pipe 21 and sprayed onto the surface of the small brush bristles 19.

[0028] like Figure 3 As shown, multiple scrapers 4 are fixed to the inner wall of the impurity removal barrel 1; the scrapers 4 are L-shaped; during operation, when the small brush bristles 19 are wrapped around the fiber cloth, they will come into contact with the ends of the scrapers 4 when rotating. When they come into contact, the scrapers 4 will cut the tangled cloth into smaller pieces, thereby reducing mutual interference when the small brush bristles 19 rotate; by adding scrapers 4, the tangled impurities can be processed by the scrapers 4 when the small brush bristles 19 rotate, thus making the cleaning after removing the small brush bristles 19 more convenient and making it easier to remove after being divided.
[0029] like Figures 1 to 3 As shown, a cylinder 5 is fixedly connected to the outer wall of the collection box 101; a pressing plate 52 is fixedly connected to the output end of the cylinder 5; a filter screen 51 is fixedly connected to the middle of the collection box 101; the filter screen 51 and the pressing plate 52 are slidably connected; during operation, when the sludge after impurity removal enters the collection box 101 through the discharge port 11, it will come into contact with the filter screen 51. At this time, the cylinder 5 can be started, and the cylinder 5 will drive the pressing plate 52 to push the sludge closer to the inner wall of the collection box 101. Then the pressing plate 52 will continuously squeeze the sludge. When squeezing, the water inside the sludge will be discharged, and then it will flow into the bottom of the collection box 101 through the filter screen 51; by adding the pressing plate 52, the sludge can be squeezed to discharge the water inside, thus making it more convenient to remove the sludge.
[0030] like Figures 2 to 4 As shown, coarse brush bristles 6 are fixed to the top of the processing rod 14; multiple coarse brush bristles 6 are arranged on the processing rod 14; during operation, when the sludge is poured into the impurity removal tank 1, it will first come into contact with the coarse brush bristles 6. At this time, the coarse brush bristles 6 will first intercept the larger impurities, and then the remaining sludge will continue to move downward. Then, when rotating, the large impurities will gradually wrap around the surface of the coarse brush bristles 6, and the remaining impurities will wrap around the small brush bristles 19, thereby performing graded impurity removal; by increasing the number of coarse brush bristles 6, the impurities can be quickly graded and processed through the contact between the small brush bristles 19 and the coarse brush bristles 6 after the sludge enters.
[0031] Working principle: Sludge is first poured into the impurity removal tank 1 through the feed inlet 13. Upon entering, the sludge first contacts the small brush bristles 19. As it moves downwards, the internal fiber cloth contacts and is intercepted by the small brush bristles 19. At this point, the processing rod 14 can be connected to a power source to rotate. During rotation, the small brush bristles 19 agitate the fiber cloth inside the sludge, causing it to become entangled within themselves. After agitation and entanglement, the sludge is discharged through the discharge outlet 11 into the collection box 101. Then, the locking block 18 can be pressed into the spring telescopic rod 17, and the impurity removal process continues. Slide rod 16 out of the processing rod 14. After removing rod 16, the fiber cloth wrapped around the small brush bristles 19 can be treated. Then, rod 16 can be installed back into processing rod 14. When the small brush bristles 19 are wrapped with sludge, water pipe 23 can be connected to a water pump. Water will first flow through water pipe 23 into transmission pipe 22, and then through connecting pipe 21 into flushing nozzle 2, spraying onto the surface of small brush bristles 19. At this time, the sludge attached to the small brush bristles 19 can be washed away and quickly fall to the bottom of the cleaning tank 1. When the sludge enters the cleaning tank 1, the sludge can be removed from the cleaning tank 1. After entering the sludge bin 1, the processing rod 14 drives the small brush bristles 19 to agitate the sludge. During agitation, some sludge is flung away. When flung away, the baffle 3 blocks the sludge approaching the feed inlet 13, intercepting it. When the small brush bristles 19 are wrapped with fiber cloth, they will contact the end of the scraper 4 during rotation. Upon contact, the scraper 4 will cut the intertwined cloth into smaller pieces, thus reducing mutual interference when the small brush bristles 19 rotate. After the sludge is cleaned, it enters the collection box 101 through the discharge port 11 and contacts the filter screen 51. At this time, the cylinder can be... When cylinder 5 is started, cylinder 5 will drive the extrusion plate 52 to push the sludge towards the inner wall of the collection box 101. Then, the extrusion plate 52 will continuously extrude the sludge, and when extruding, the water inside the sludge will be discharged. Then, it will flow into the bottom of the collection box 101 through the filter screen 51. When the sludge is poured into the impurity removal bucket 1, it will first come into contact with the coarse brush bristles 6. At this time, the coarse brush bristles 6 will first intercept the larger impurities, and then the remaining sludge will continue to move downward. Then, when rotating, the large impurities will gradually wrap around the surface of the coarse brush bristles 6, and the remaining impurities will wrap around the small brush bristles 19, thereby performing graded impurity removal.
