[0041] The working principle of this utility model is as follows:

[0042] like Figures 1 to 16 As shown, when sewage enters the outer cylinder 1 through the inlet cylinder 11, the drive motor 2 is started, and the drive shaft 14 drives the four cutter holders and three auger blade sleeves 55 to rotate together, and also drives the sewage to rotate. The blades on the four cutter holders cut the waste residue in the sewage during rotation. It should be noted that although the cutting edge direction of the first blade 513, the second blade 523, the third blade 533 and the fourth blade 543 are all in the same direction as the rotation of the drive shaft 14, the sewage flow velocity in the outer ring away from the drive shaft 14 will decrease, while the rotation speed of the drive shaft 14 remains unchanged, that is, the cutting speed of the twelve blades remains unchanged. The resulting speed difference can fully crush the waste residue, and the leachate that meets the filtration standard flows out after filtration. It should be noted that nine blades 3 are spirally arranged at equal intervals on the inner wall of the outer cylinder 1, which work with the blades on the cutter holders to further crush the waste residue, so as to achieve the purpose of refining the waste residue and thus avoid clogging of the leachate discharge. In addition, since a drain pipe 131 is provided, it can also quickly remove blockages if there is poor discharge or cleaning is required.

[0043] In the process, due to the complex components in the leachate, inevitably contains alkali metal, in order to avoid the leachate to the internal device caused by scaling and affect the normal operation, set the tension device, the first groove wheel 421 and the second groove wheel 422 in the tension device respectively with the inner side wall position of the corresponding end of the belt sliding abutment, support the belt tension, the nut of the limiting bolt 45 abuts in the slot position of the first sliding groove 421, the inner side wall of the adjusting nut 451 abuts in the slot position of the second sliding groove 422, the rotation of the limiting support plate 42 makes the belt drive keep tight state; when the belt wears, the tension degree is loose, rotate the adjusting nut 451, push the support plate 42 to rotate counterclockwise, when the two groove wheels abut against the belt again and keep tight state, abut against the nut position, the nut abuts in the slot position of the first sliding groove 421, make the support plate 42 keep stationary, rivet the adjusting nut 451 again, the inner side wall of the adjusting nut 451 abuts in the slot position of the second sliding groove 422 again, realize the purpose of adjusting the tension of the belt.

[0044] Among them, since the support plate 42 is connected by the sleeve joint of the support rod 41 and the middle circle position of the bearing, and the middle circle of the bearing can rotate under force, that is, one end of the support plate 42 can rotate under force, when the support plate 42 rotates, the two ends of the limiting bolt 45 will also have adaptive rotation and horizontal displacement in the horizontal direction, the support plate 42 and the limiting block 44 are provided with a spacing, and the first sliding groove 421 and the second sliding groove 422 are provided with a spacing, which provides a space for the adaptive rotation of the two ends of the limiting bolt 45, so as to meet the need of adjustment.
