[0038] The implementation principle of the internal spray internal inlet grid decontamination machine of the present application embodiment is as follows: the length direction of the frame 1 is parallel to the water flow direction, so that the water flow can flow in from the water inlet 2, and the reduction motor 5 is started. The reduction motor 5 runs more stably under the support of the support frame 10, and the reduction motor drives the transmission wheel 27 to rotate, and the transmission chain 4 and the transmission wheel 27 are meshed with each other, and the filter grid belt 20 is fixedly connected to the transmission chain 4. At this time, the filter grid belt 20 moves along the running direction of the transmission chain 4. After the sewage enters from the water inlet 2, due to the closure on the opposite side of the frame 1 located at the water inlet 2, the water flow can only flow out from the filter grid belt 20, and the sewage inside When the solid impurities contact the filter grating belt 20, they will be stuck in the gap of the filter grating belt 20 and move with the filter grating belt 20, while the solid impurities smaller than the aperture of the filter grating belt 20 will pass through the filter grating belt 20 and be intercepted by the orifice plate 21. At this time, the interception plate 26 on the outside of the filter grating belt 20 moves with the filter grating belt 20. When passing through the gap between the orifice plate 21 and the filter grating belt 20, the toothed structure on the interception plate 26 scrapes the impurities on the orifice plate 21 and attaches them to the interception plate 26. When installing the orifice plate 21, first insert the orifice plate 21 from the through groove (not shown in the figure) and slide the orifice plate 21 downward to the T-shaped slide groove 25.

[0039] At this time, water is pumped by the pressure cleaning pump 12, and water flows into the pressure washing head 17 through the hose 15 and flushes to the outside of the filter grid belt 20. The bidirectional transmission screw 7 rotates with the reduction motor 5. The guide of the slide 11 prevents the pressure washing head 17 from rotating, so that the pressure washing head 17 reciprocates along the slide 11 to wash the outside of the filter grid belt 20 and the impurities on the intercepting plate, and wash the impurities into the drainage pipe 23. There may be residual impurities inside the filter grid belt 20. The inner side of the filter grid belt 20 is sprayed by the internal spraying washing head 17 to reduce the possibility of residual impurities in the filter grid belt 20. In addition, by setting the inspection port 6, it is convenient for the staff to observe the internal situation of the frame 1, which is convenient for subsequent maintenance.
