A protruding overlapping ring 4 is fixedly connected to the inner wall of the main pipe 1. The height of the overlapping ring 4 is lower than the height of the branch pipe 2. A filter plate 5 is movably mounted on the overlapping ring 4. The external dimensions of the filter plate 5 are adapted to the diameter of the main pipe 1 cavity so that the filter plate 5 can move axially within the cavity of the main pipe 1. A first slot 11 is provided at the upper end of the main pipe 1. A first locking block 31 is integrally connected to the outer peripheral wall of the cover plate 3. The first locking block 31 is adapted to the first slot 11. When the cover plate 3 is placed on the main pipe 1, the first locking block 31 is engaged. Block 31 is snapped into the first slot 11, so that the cover plate 3 will not rotate on the main pipe 1; the filter plate 5 is provided with a unclogging mechanism 6 for unclogging the filter plate 5. The unclogging mechanism 6 includes a pull frame 61 that passes through and slides between the cover plate 3 and the filter plate 5. The pull frame 61 is an inverted U-shape. One end of the pull frame 61 located below the cover plate 3 is fixedly connected to a connecting frame 62. The connecting frame 62 includes a base frame 621, a connecting rod 623 and an unclogging rod 63. The base frame 621 is fixedly connected to the pull frame 62. The unclogging rod 63 is fixed on the connecting rod 623. Filter holes 54 are distributed on the filter plate 5. The unclogging rod 63 is arranged in a one-to-one correspondence with the filter holes 54. The unclogging rod 63 can pass through the filter holes 54. A scraper ring 7 is provided on the edge of the filter plate 5 away from the base frame 621. The outer ring wall of the scraper ring 7 contacts the inner wall of the main pipe 1.

[0023] During unblocking, pull the pull bracket 61 upwards from outside the main pipe 1 to bring the connecting bracket 62 close to the filter plate 5 until the unblocking rod 63 penetrates the filter hole 54 of the filter plate 5. Quickly pull the pull bracket 61 up and down to unblock the filter plate during sewage discharge, which is simple and quick. The outer wall of the scraper ring 7 is close to the inner wall of the main pipe 1. Pull the pull bracket 61 upwards to bring the connecting bracket 62 close to and in contact with the filter plate 5. Continue to pull upwards to move the filter plate 5 and the connecting bracket 62 upwards. During the upward movement, the scraper ring 7 can scrape and clean the impurities adhering to the inner wall of the main pipe 1.

[0024] like Figures 1 to 5As shown, a collection mechanism 8 is provided between the cover plate 3 and the filter plate 5. The collection mechanism 8 is used to collect the waste on the filter plate 5. The collection mechanism 8 includes a rotating rod 81 whose lower end is connected to the filter plate 5 via a bearing. The rotating rod 81 is located at the center of the filter plate 5. A drive motor 82 is located on the cover plate 3. The output shaft of the drive motor 82 passes through the cover plate 3 and is connected to the upper end of the rotating rod 81. A cleaning assembly is fixedly connected to the lower side wall of the rotating rod 81. The cleaning assembly includes a crossbar 83. The axis of the crossbar 83 is perpendicular to the rotating rod 81. The axis, the lower end of the crossbar 83 near the rotating rod 81, is spaced apart from the filter plate 5. Multiple inclined cleaning rods 84 are fixedly connected to the crossbar 83. The cleaning rods 84 are arranged along the axial direction of the crossbar 83. Some of the cleaning rods 84 are located in the space and face the filter plate 5. The end of the cleaning rod 84 away from the crossbar 83 has a narrow gap with the filter plate 5. An installation through hole 51 is opened on the filter plate 5. A collection box 85 is detachably installed in the installation through hole 51. Several water passage holes are opened on the collection box 85.

[0025] The output of the drive motor 82 causes the rotating rod 81 to rotate, and the cleaning rod 84 on the crossbar 83 moves some of the garbage accumulated on the filter plate 5 and pushes the garbage to the collection box 85. Under the flow of sewage falling from above, the garbage enters the collection box 85. The collection mechanism 8 can further reduce the probability of filter plate 5 clogging. When the filter plate 5 is unblocked, the rotation of the drive motor 82 is controlled to rotate the crossbar 83 above the collection box 85 so as not to affect the use of the unblocking mechanism 6.

[0026] like Figures 1 to 5 As shown, the filter plate 5 has a second slot 52 at both ends of the mounting through hole 51. The outer walls of both ends of the collection box 85 are fixedly connected with a second block 851 that matches the second slot 52. After the collection box 85 is inserted into the mounting port 51, the second block 851 is just locked into the second slot 52.

[0027] like Figure 4 As shown, the inner walls of the collection box 85 on both sides are provided with first snap-fit ​​grooves 852. After the filter plate 5 is taken out from the main pipe 1, the collection box 85 can be easily snapped out by setting the first snap-fit ​​grooves 852 and the garbage inside can be cleaned.

[0028] like Figure 3 As shown, a second groove 53 is provided on the outer wall of the filter plate 5 to facilitate the removal of the filter plate 5.

[0029] like Figure 3As shown, the pull frame 61 includes two vertical arms 612 and a horizontal arm 613. The two vertical arms 612 are located at both ends of the horizontal arm 613. The filter plate 5 and the cover plate 3 are symmetrically provided with through holes for the vertical arms 612 to pass through. The through holes are opposite to the vertical arms 612, and the vertical arms 612 can move in the through holes. The vertical arms 612 pass through the through holes of the cover plate 3 and the filter plate 5 from above and are then connected and fixed to the base frame 621.

[0030] like Figure 3 As shown, the base frame 621 is annular, with a central disk 622 at the center. The connecting rod 623 extends along the inner radius of the base frame 621, and its two ends are connected to the central disk 622 and the base frame 621 respectively. The filter holes 54 on the filter plate 5 are radially radiating. The unblocking rod 63 is fixedly connected to the connecting rod 623. The filter holes 54 are arranged at intervals along the radial direction of the filter plate 5.

[0031] like Figure 4 As shown, a limiting block 611 is provided on the vertical arm 612. The limiting block 611 is located at the upper end of the filter plate 5 and is used to limit the vertical displacement of the pull frame 61.

[0032] In this invention, the drive motor 82 is electrically connected to an external power supply and to a control unit (not shown in the figure).

[0033] In use, sewage enters the main pipe 1 through the branch pipe 2. The output of the drive motor 82 causes the rotating rod 81 to rotate. The cleaning rod 84 on the crossbar 83 moves some of the garbage accumulated on the filter plate 5 and pushes the garbage to the collection box 85. Under the flow of sewage falling from above, the garbage enters the collection box 85. If the filter plate 5 is blocked, the pull bracket 61 is pulled up and down quickly so that the unblocking rod 63 repeatedly passes through the filter holes of the filter plate 5. The filter plate can be unblocked during sewage discharge. It is simple and quick. In daily sludge cleaning, the debris covering the filter hole 54 can be lifted by repeatedly pushing and pulling the pull bracket 61, and then the debris can be flushed into the collection box 85 by flushing water.
