[0029] like Figure 5 As shown, an elastic plate 6 is fixedly connected to the top of the impact block 36; the top of the elastic plate 6 fits with the outer surface of the filter screen 3; when working: the elastic plate 6 is made of elastic material, and when the impact block 36 hits the filter screen 3 at high frequency, the elastic plate 6 first contacts with the filter screen 3, thereby reducing the material loss when the impact block 36 collides with the filter screen 3 at high frequency for a long time.
[0030] like Figure 3 As shown, the outer wall of the tooth 15 is fixedly connected with multiple groups of friction soft plates 7; when working: the friction soft plates 7 are made of elastic material, and when the gear 13 and the tooth 15 are meshed and rotated with each other, the friction soft plates 7 first contact with the gear 13, and the friction soft plates 7 reduce the friction and rotation of the tooth 15 with the gear 13 for a long time, resulting in more serious surface wear, thereby improving the working life of the tooth 15.
[0031] Working principle: when working: start the first motor 11 to drive the gear 13 to rotate. Because the gear 13 and the teeth 15 are meshed with each other, the teeth 15 and the shaft 14 are connected to each other. The gear 13 drives the shaft 14 to rotate during its rotation, and the connecting plate 17 is connected to the shaft 14 through the fixing plate 16. During the rotation of the shaft 14, the connecting plate 17 rotates accordingly. At this time, the scraper 18 can scrape and clean the waste residue adhered to the inner wall of the centrifuge body 1, thereby reducing the waste residue adhered to the inner wall of the centrifuge body 1. The residue will interfere with the sedimentation and separation of particles during the centrifugation process, resulting in a decrease in separation efficiency, thereby improving the cleanliness of the upper surface of the inner wall of the centrifuge body 1. At this time, the scraped and cleaned The waste residue is discharged into the slag collecting box 110 through the discharge hopper 112 for collection; 18 is fixed to the inner side of 17 by rotating multiple groups 19, and when replacing 18, only 19 needs to be loosened to take out and replace 18, thereby improving the overall work efficiency of the staff when replacing 18; first, water is added to the water collecting box 2 through the water inlet pipe 21, and the water pump 23 is started to make the water inside the water collecting box 2 enter the water storage tank 24 through the water supply pipe 22. At this time, multiple groups of nozzles 25 can wash the fine waste residue remaining on the inner wall of the centrifuge body 1, thereby reducing the scraper 18 The surface material is relatively hard, and when scraping and cleaning the waste residue on the inner wall of the centrifuge body 1, it is easy to cause the fine waste residue to still stick to the centrifuge. The situation occurs on the inner wall of the centrifuge body 1, thereby further improving the cleanliness of the upper surface of the inner wall of the centrifuge body 1; through the filter screen 3 arranged on the inner side of the slag box 110, the waste slag scraped and cleaned from the inside of the centrifuge body 1 passes through the discharge hopper 112 and stays on the surface of the filter screen 3 inside the slag box 110. At this time, the second motor 31 is started to drive the eccentric wheel 32 to rotate, and the eccentric wheel 32, the first slide groove 33, the slide column 34 and the impact block 36 cooperate with each other to make the impact block 36 slide up and down back and forth on the inside of the fixed block 35, so as to achieve the effect of high-frequency impact of the impact block 36 on the surface of the filter screen 3. At this time, the waste slag staying on the surface of the filter screen 3 will pass through the high-frequency impact when it is subjected to the high-frequency impact. The slag discharge port 111 is discharged to the outside, thereby improving the overall work efficiency of the staff when cleaning the waste residue retained on the surface of the filter screen 3; in addition, the waste water generated when the fine waste residue adhering to the inner wall of the centrifuge body 1 is washed by the nozzle 25 enters the inner side of the slag collecting box 110 through the discharge hopper 112, and the waste water inside the slag collecting box 110 can be discharged to the outside through the drain pipe 37; when the water pump 23 inside the water collecting box 2 needs to be repaired and maintained, because the handle 42 and the baffle 41 are connected to each other, at this time, the handle 42 is pulled to move the baffle 41 to the inner side of the second chute 4, and the water pump 23 inside the water collecting box 2 can be taken out for repair and maintenance, thereby improving the overall work efficiency when the water pump 23 is repaired and maintained;When the impact block 36 moves up and down through the fixed block 35, the multiple sets of fitting rotating posts 51 rotate accordingly. The multiple sets of fitting rotating posts 51 reduce the long-term sliding friction between the inner wall of the fixed block 35 and the outer wall of the impact block 36, which causes the surface wear of the impact block 36 to be more serious, thereby improving the service life of the impact block 36; the elastic plate 6 is made of elastic material. When the impact block 36 hits the filter screen 3 at high frequency, the elastic plate 6 first contacts the filter screen 3, thereby reducing the material loss when the impact block 36 collides with the filter screen 3 at high frequency for a long time; the friction soft plate 7 is made of elastic material. When the gear 13 and the tooth 15 mesh and rotate with each other, the friction soft plate H7 first contacts the gear 13. The friction soft plate 7 reduces the long-term friction rotation of the tooth 15 with the gear 13, which causes the surface wear to be more serious, thereby improving the service life of the tooth 15. ;
