DETAILED DESCRIPTION

[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0025] A wastewater filtering device, such as Figure 1 and Figure 2 As shown, it includes a filter box 10, which is a hollow rectangular box. A filter component for rotating and filtering wastewater is arranged in the cavity of the filter box 10, and a second filter screen 11 is also arranged below the filter component.

[0026] like Figure 2 , Figure 3 , Figure 5As shown, the filter assembly includes a filter cartridge 14 fixedly mounted between the front and rear walls of the filter box 10 cavity, a liquid inlet pipe 15 fixedly mounted on the top of the filter cartridge 14, the liquid inlet pipe 15 passes through the top wall of the filter box 10, a liquid outlet pipe 18 fixedly mounted on the bottom of the filter cartridge 14, the liquid outlet pipe 18 is located above the second filter screen 11, and the filter cartridge 14 is a hollow cylinder. A rotating column 20 is rotatably mounted in the cavity of the filter cartridge 14, and multiple groups of filter screen frames 21 are fixedly connected to the outer wall of the rotating column 20. The side of the filter screen frame 21 away from the rotating column 20 is arc-shaped, and the arc-shaped outer wall of the filter screen frame 21 is in contact with the inner wall of the filter cartridge 14, and the inner wall of the filter screen frame 21 is fixedly mounted with a first filter screen 22. A first motor 19 is fixedly mounted on the front outer wall of the filter box 10 via a triangular plate, the output end of the first motor 19 movably penetrates the front wall of the filter box 10, the front wall of the rotating column 20 movably penetrates the filter cylinder 14, and the output end of the first motor 19 is fixedly connected to the front end of the rotating column 20.

[0027] like Figure 2 , Figure 3 , Figure 4 As shown, a swing structure for reciprocatingly impacting the filter frame 21 is provided in the cavity of the liquid outlet pipe 18, and the swing structure includes a rotating rod 31, which is rotatably installed between the front and rear side walls of the cavity of the liquid outlet pipe 18. A second motor 30 is also installed on the front side wall of the filter box 10 through a triangular plate, and the second motor 30 is located below the first motor 19. The front end of the rotating rod 31 movably penetrates the front side wall of the liquid outlet pipe 18, and the output end of the second motor 30 is fixedly connected to the rotating rod 31. The rotating rod 31 is located on the outer wall of the cavity of the liquid outlet pipe 18, and a rotating sleeve 32 is fixedly inserted therein. A slide groove 36 is provided in the middle of the left side wall of the rotating sleeve 32, and the slide groove 36 is arc-shaped. An arc-shaped guide rod 37 is fixedly installed in the cavity of the slide groove 36, and a sliding sleeve 33 is movably inserted on the guide rod 37. A vertical upward moving plate 34 is fixedly installed on the top wall of the sliding sleeve 33. A spring 38 is also inserted into the left outer wall of the guide rod 37, and the spring 38 presses the sliding sleeve 33 to the right. A rubber pad 35 is also fixedly installed on the right wall of the moving plate 34, and the rotation of the filter frame 21 squeezes and pushes the rubber pad 35.

[0028] like Figure 1 and Figure 2As shown, the pushing assembly includes a hydraulic cylinder 12 fixedly mounted on the left wall surface of the cavity of the filter box 10, the piston rod of the hydraulic cylinder 12 is fixedly connected with a shovel plate 13, the hydraulic cylinder 12 is parallel to the second filter screen 11, the shovel plate 13 is in contact with the wall surface of the second filter screen 11, a sewage outlet 16 is provided on the right wall surface of the filter box 10, a collecting box 17 is fixedly mounted on the right wall surface of the filter box 10, the sewage outlet 16 corresponds to the position of the shovel plate 13, a window is also provided on the front wall surface of the filter box 10, a first cabinet door 23 is sealedly mounted in the window, a window is also provided on the right wall surface of the collecting box 17, a second cabinet door is mounted in the window, and a sewage pipe is mounted at the bottom center position of the filter box 10.

[0029] When in use, the sewage is injected into the cavity of the filter box 10 through the liquid inlet pipe 15, and the working switches of the first motor 19 and the second motor 30 are turned on. When the first motor 19 is working, the first motor 19 drives the rotating column 20 to rotate, and the rotating column 20 drives the filter frame 21 to rotate. After the sewage enters the cavity of the filter cylinder 14, it can quickly pass through the filter cylinder 14 under the action of gravity, and the impurities in the sewage can be completely filtered out by the first filter screen 22. The filter screen frame 21 drives the rotation of the first filter screen 22, and the impurities in the sewage will not block the first filter screen 22. Because the first filter screen 22 rotates, the impurities will not always pass through the surface of one first filter screen 22. Multiple first filter screens 22 filter the impurities in an all-round way, and the filtration efficiency of the sewage can also be guaranteed.

[0030] When the working switch of the second motor 30 is turned on, the second motor 30 drives the rotating rod 31 to rotate, the rotating rod 31 drives the rotating sleeve 32 to rotate, and the rotating sleeve 32 drives the moving plate 34 to rotate. At this time, the moving filter frame 21 collides with the rubber pad 35, so that the filter frame 21 pushes the moving plate 34 through the rubber pad 35, and the sliding sleeve 33 slides along the outer wall of the guide rod 37, so that the spring 38 is compressed. After the filter frame 21 contacts and separates from the rubber pad 35, under the elastic force of the spring 38, the moving plate 34 and the rubber pad 35 can be reset and contact and collide with the next filter frame 21 again.

[0031] When the rubber pad 35 collides with the filter frame 21, or when the filter frame 21 collides with the rubber pad 35, the first filter screen 22 can be shaken once. The first filter screen 22 is elastic. Even if the filter frame 21 is fixedly connected to the rotating column 20, the first filter screen 22 can be slightly shaken under the action of the impact. When the first filter screen 22 shakes, the impurities on the filtering surface of the first filter screen 22 can be shaken off. The impurities shaken off fall onto the second filter screen 11 through the liquid outlet pipe 18, and the sewage falls down through the second filter screen 11 and can be discharged through the sewage pipe at the bottom of the filter box 10. After the impurities fall on the second filter screen 11, the working switch of the hydraulic cylinder 12 is turned on. When the hydraulic cylinder 12 works, the shovel plate 13 is pushed by the piston rod. The shovel plate 13 follows the inclined surface of the second filter screen 11 to push all the impurities into the sewage outlet 16, and then enters the collection box 17 from the sewage outlet 16 for storage.

[0032] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
