[0026] As attached Figure 3As shown, in the above embodiment, specifically, the filtered material collector 6 includes a discharge elbow 61, an outer bracket 62 is integrated at the lower right portion of the discharge elbow 61, a positioning groove 63 is provided on the inner side of the outer bracket 62, a sliding sleeve 64 is sleeved at the lower right portion of the discharge elbow 61, and a collecting bag extrusion plate 65 is integrated at the right side of the sliding sleeve 64.
[0027] As attached Figure 4 As shown, in the above embodiment, specifically, the discharging anti-blocking mechanism 8 includes a sleeve limit seat 81, a discharging ejector rod 82 is inserted into the left side of the interior of the sleeve limit seat 81, the upper rear end axis of the discharging ejector rod 82 is connected to an intermediate connecting rod 83, and the upper rear end axis of the intermediate connecting rod 83 is connected to a rotating crank rod 84.
[0028] In the above embodiment, specifically, the filtrate discharge pipe 32 is fixed to the upper left portion of the inner side of the discharge elbow 61 , and the lower right portion of the discharge elbow 61 extends to the lower right portion of the outer side of the mounting shell 1 .
[0029] In the above embodiment, specifically, the sliding sleeve 64 and the collecting bag squeezing plate 65 are respectively arranged on the outside of the mounting housing 1 , and the outer side of the sliding sleeve 64 is threadedly connected with a locking bolt.

[0032] How it works
[0033] The working principle of the utility model is as follows: the staff introduces sewage into the upper left inner side of the installation shell 1 through the sewage feed pipe 2, and the sewage falls into the left half of the disc-type double-tilt bracket 31. Since the left side of the disc-type double-tilt bracket 31 is tilted toward the lower left, the sewage will flow toward the lower left in large quantities, and the sewage will pass through the sewage filter net 35 on the left side of the disc-type double-tilt bracket 31 and flow downward into the inner side of the sewage collection bucket 4, and finally be discharged from the filter collector 6. At the same time, the drive motor 33 drives the filter cleaning plate 34 to rotate, and moves the filter on the left side of the disc-type double-tilt bracket 31 to the right side of the disc-type double-tilt bracket 31. Since the right side of the disc-type double-tilt bracket 31 is tilted toward the lower right, the filter will roll toward the lower right along the tilt direction, and at the same time, the sewage carried in the filter will pass through the sewage filter net 35 on the right side of the disc-type double-tilt bracket 31 and flow downward. The filtered material will flow back into the inner side of the sewage collecting bucket 4, and the filtered material will enter the inner side of the discharge elbow 61 through the filtered material discharge pipe 32. The staff also needs to put the collecting bag on the outer side of the outer bracket 62 in advance, and place the opening edge of the collecting bag to the inner side of the positioning groove 63. The collecting bag extrusion plate 65 is pushed to move to the inner side of the positioning groove 63 by the sliding sleeve 64 to fix the edge of the collecting bag. The filtered material falls into the inner side of the collecting bag through the discharge elbow 61. When the filtered material is blocked in the upper part of the discharge elbow 61, the output shaft of the rotating motor 7 will drive the rotating crank rod 84 to rotate. After being connected with the intermediate connecting rod 83, the discharge push rod 82 is made to reciprocate vertically on the inner side of the sleeve limit seat 81, thereby pushing the filtered material accumulated on the upper part of the discharge elbow 61 to the inner side of the discharge elbow 61 for dredging.
[0034] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
