[0024] Please see attached Figure 1 -Attached Figure 8In a preferred embodiment, a first pulley 12 is fixed to the bottom of the lower turntable 10, a second pulley 13 is rotatably installed at the bottom of the barrel body 1, and the first belt 11 is sleeved on the surfaces of the first pulley 12 and the second pulley 13, a first motor 14 is installed at the bottom of the barrel body 1, and the output shaft of the first motor 14 is installed at the bottom center of the second pulley 13, a bracket 2 is fixedly installed on the surface of the barrel body 1, a first annular groove 19 is opened at the top of the upper turntable 3, a ring 6 is slidably installed inside the first annular groove 19, and four sewage inlet grooves passing through the upper turntable 3 are opened at the top of the first annular groove 19, a circular groove matching the sewage inlet groove is opened at the top of the ring 6, a sewage inlet pipe 7 is vertically fixedly installed inside the circular groove, an L-shaped frame is fixed on the top of the bracket 2, and the surface of the sewage inlet pipe 7 is fixedly installed inside the horizontal edge of the L-shaped frame; Furthermore, the first motor 14 is used to drive the filter assembly and the cleaning assembly to rotate and switch, thereby realizing continuous cleaning of the net cylinder and sewage filtering.

[0025] The working principle of the present invention is as follows: first, the sewage inlet pipe 7 is connected to the sewage pipe externally, and then the sewage will enter the inside of the connecting pipe 30 from the sewage inlet pipe 7 through the sewage inlet groove, and the sewage inside the connecting pipe 30 will enter between the cover tube 16 and the first net tube 28, and then the filter holes formed by the misalignment of the first net tube 28 and the second net tube 34 will filter the sewage, and the filtered sewage will enter the drain pipe 18 through the first net tube 28 and the second net tube 34, and finally the sewage inside the drain pipe 18 will fall into the collection box 9 and be collected. It should be noted that the collection box 9 is connected with a pumping pipe to facilitate the extraction of the sewage inside the collection box 9; When the filter holes formed by the corresponding first mesh cylinder 28 and the second mesh cylinder 34 are blocked, the first motor 14 is started to drive the second pulley 13, the first belt 11 and the first pulley 12 to rotate, the first pulley 12 rotates to drive the lower turntable 10 to rotate, the lower turntable 10 rotates to drive the four drainage pipes 18 to rotate, the four drainage pipes 18 rotate to drive the base 17 to revolve, the base 17 revolves to drive the first mesh cylinder 28, the spring rod 35, the second mesh cylinder 34, the cover cylinder 16 and the upper turntable 3 to revolve, so that the four filtering mechanisms and the cleaning mechanism can change their positions. Due to the arrangement of the first arc groove 26 and the second arc groove 27, when the sliding column 33 moves from the second arc groove 27 to the first arc groove 26, it will move upward, and the sliding column 33 moves upward to drive the cover cylinder 16 to move upward. At this time, the bottom of the first mesh cylinder 28 will no longer be blocked by the cover cylinder 16. It should be noted that the connecting pipe 30 and the cover cylinder 16 are connected by a spline sliding connection to ensure the stability of the cover cylinder 16 moving upward. Then, the corresponding air pump 4 and the second motor are started. The operation of the air pump 4 can allow external gas to enter the interior of the sleeve 20 through the vertical pipe 5. The gas inside the sleeve 20 is ejected through the air outlet head 36, so as to realize jetting from the inside of the second net cylinder 34 to the outside to remove impurities on the first net cylinder 28 and the second net cylinder 34. The operation of the second motor drives the third pulley 25, the second belt 24 and the ring 23 to rotate. The rotation of the ring 23 drives the sleeve 20 to rotate. The rotation of the sleeve 20 drives the air outlet head 36 and the disc 31 to rotate, so as to realize comprehensive cleaning of the first net cylinder 28 and the second net cylinder 34. In addition, the rotation of the disc 31 will cause the plug block 37 to pass through the slope on the rectangular groove 38, so that the plug block 37 moves downward. The downward movement of the plug block 37 drives the second net cylinder 34 to move downward and causes the spring rod 35 to generate elastic force. At this time, the first net cylinder 28 and the second net cylinder 34 are no longer misaligned, and the filter holes formed by the first net cylinder 28 and the second net cylinder 34 become larger, which is convenient for the air outlet head 36 to blow impurities away from the net cylinder. The characteristics after that, when the disc 31 rotates, the T-shaped slider 40 will enter the rectangular groove 38. It should be noted that after the T-shaped slider 40 enters the rectangular groove 38, its top end is still located in the T-shaped arc groove 39, so as to achieve the blocking of the rectangular groove 38, and avoid the situation that the plug block 37 enters the rectangular groove 38 again when the disc 31 rotates. In addition, due to the setting of the reciprocating spiral groove 22 inside the vertical pipe 5, the rotation of the sleeve 20 will drive the circular protrusion 21 to rotate, and will also move along the reciprocating spiral groove 22 as a path, further making the circular protrusion 21 drive the sleeve 20 and the air outlet head 36 to move up and down, and the air outlet head 36 moves up and down to comprehensively clean the impurities on the enlarged filter hole. It should be noted that when the air outlet head 36 moves down to the top surface of the base 17, the impurities will be blown into the barrel body 1. In this process, the corresponding filtering component and cleaning component will continue to filter the sewage, so as to achieve the cleaning of the net cylinder and the filtration of the sewage can be carried out simultaneously; Then the first motor 14 is operated to drive the filter assembly and the cleaning assembly to rotate, which will cause the cleaned first net cylinder 28, the second net cylinder 34 and the cover cylinder 16 to revolve, and the sliding column 33 on the cleaned cover cylinder 16 will enter the second arc groove 27 from the first arc groove 26, and the sliding column 33 will drive the cover cylinder 16 to move downward and abut against the base 17 for sealing, thereby ensuring the effect of subsequent sewage filtration; In summary, the net cylinder can be cleaned and sewage can be filtered continuously by reciprocating in sequence, and it is convenient and quick to use, thereby improving the use effect of the equipment.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
