The filtrate outlet pipe 26 is vertically arranged and is positioned above the top of the primary sedimentation tank 1. Before the sewage enters the filter box 19, the slag discharge port 27 is positioned below the support ring 24, when more and more filter residues are accumulated on the filter screen 20, the filter screen 20 and the support ring 24 gradually move downwards along with the increase of the filter residues, and at the moment, the slag discharge port 27 is positioned above the filter screen 20 and the support ring 24 or just above the filter screen 20 and the support ring 24.
Referring to fig. 1-6, the filter tank 19 is provided with a slag removal assembly 6, a screw rod assembly 7, a driving assembly 8 and a flow guide assembly 9, and the slag removal assembly 6 and the flow guide assembly 9 are both positioned in the filter tank 19. The slag removing assembly 6 is located above the filter screen 20 and used for pushing the filter residue on the filter screen 20 to the direction close to the slag discharge port 27, so that the filter residue accumulated on the filter screen 20 is discharged outwards through the slag discharge port 27 and the slag discharge pipe 10. The driving assembly 8 is used for driving the screw rod assembly 7 to drive the slag removing assembly 6 to move back and forth above the filter screen 20 through the screw rod assembly 7, and the flow guide assembly 9 is used for guiding sewage to flow so as to limit the sewage from the other side of the slag removing assembly 6 relative to the slag discharging port 27 to enter the filter box 19. The driving assembly 8 is used for triggering the screw rod assembly 7 in the downward moving process of the filter screen 20 so as to drive the slag removing assembly 6 to scrape off filter residues on the filter screen 20.
In the technical scheme, in order to automatically and timely discharge filter residues outwards, the filter box 19 is internally provided with the residue cleaning assembly 6, the screw rod assembly 7, the driving assembly 8 and the flow guide assembly 9. When sewage passes through sewage inlet 11 and gets into rose box 19, water and the tiny particle impurity in the sewage will pass filter screen 20 and get into hopper 21 down, and get into primary sedimentation tank 1 under the transport of filtrating outlet pipe 26, and the large granule solid impurity in the sewage is because unable filter screen 20 that passes through, consequently can only pile up on filter screen 20, along with the accumulational filter residue on the filter screen 20 is more and more, under the action of gravity, support ring 24, filter screen 20, hopper 21 and filtrating outlet pipe 26 will move downwards gradually, drive assembly 8 will trigger lead screw subassembly 7 this moment, in order to drive slag removal subassembly 6 to pushing away the filter residue on the filter screen 20 to being close to row cinder notch 27 direction, so that the filter residue passes through row cinder notch 27, arrange the outside discharge of cinder pipe 10.
Referring to fig. 1-6, preferably, the scarfing cinder assembly 6 comprises a shroud 61, a push plate 62 and a brush 63. The sleeve plate 61 is fixed on the screw rod assembly 7, the push plate 62 is inserted into the sleeve plate 61 and is in up-and-down sliding fit with the sleeve plate 61, specifically, the sleeve plate 61 is vertically arranged, a limiting part for limiting the push plate 62 to be separated from the sleeve plate 61 downwards is arranged below the inner part of the sleeve plate 61, and the limiting part is arranged on two sides of the inner wall of the sleeve plate 61; the top of the push plate 62 is provided with a matching part which is always positioned in the sleeve plate 61. The brush 63 is fixed at the bottom of the push plate 62 and contacts with the top surface of the filter screen 20, and the brush 63 is used for brushing off solid impurities blocked in the filter holes of the filter screen 20 so as to reduce the blockage of the filter screen 20. In order to keep the brush 63 always in contact with the top surface of the filter screen 20 so that the residue on the filter screen 20 can be pushed to the residue discharge port 27 as completely as possible by the push plate 62, it is preferable that a protrusion 64 is fixed to one side of the lower portion of the push plate 62, and the protrusion 64 is located below the sleeve plate 61 and on the other side of the push plate 62 opposite to the residue discharge port 27. The top of the support ring 24 is fixed with a lower pull plate 25 for pulling the push plate 62 downward, the lower pull plate 25 comprises a vertical part and a horizontal part, and the bottom of the vertical part is fixed on the support ring 24.
