Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a filtering device for sewage treatment that is convenient for cleaning. Background Technique

[0002] When treating sewage, it is often necessary to intercept impurities in the sewage through the internal filter screen of the filtering device to filter the sewage, so as to facilitate the treatment of sewage. However, in the existing filtering devices for sewage treatment, the filter screen is fixedly installed inside the device, which is not convenient for cleaning. At the same time, when treating sewage, impurities will accumulate on the filter, blocking the filter screen and affecting the speed of sewage treatment.

[0003] The patent document with the publication number of CN211635396U in the prior art provides a filtering device for sewage treatment that is convenient for cleaning; through the design of a motor, a rotating shaft, bristles, and a connecting plate, it plays a role in cleaning the blockages on the filter screen, which is beneficial to ensuring the sewage treatment speed. At the same time, the design of the cleaning cotton and the connecting rod plays a role in cleaning the inner wall of the housing to prevent impurities from adhering. Through the telescopic rod, the fixing plate is raised, so as to take out the filter screen and clean the filter screen.

[0004] Although this device has many beneficial effects, there are still the following problems: If impurities have adhered to the filter screen, and then through this method of using bristles and cleaning cotton to clean the filter screen, it will cause the impurities to continue to adhere inside the filter screen, which will obviously reduce the cleaning efficiency and it is difficult to improve the treatment efficiency of the filter screen. For this reason, we have proposed a filtering device for sewage treatment that is convenient for cleaning. Content of the Utility Model

A filter plate 2 is arranged inside the tank body 1. A sewage discharge pipe 21 is rotatably installed on the upper side of the tank body 1. The filter plate 2 is fixedly installed at the lower end of the sewage discharge pipe 21. An outer conduit 22 is fixedly installed at the upper end of the sewage discharge pipe 21. A through cavity 29 that is communicated with its inner cavity is formed on the outer periphery of the sewage discharge pipe 21. A positioning rod 24 is fixedly installed inside the tank body 1. A guide cavity 25 is formed inside the positioning rod 24. A return flow frame 26 is inserted and installed at the lower side of the positioning rod 24. The guide cavity 25 is communicated with the inner cavity of the return flow frame 26. The lower end of the return flow frame 26 is attached to the upper end of the filter plate 2. A movable sleeve 23 that is communicated with the inner cavity of the guide cavity 25 is fixedly installed in the middle of the positioning rod 24. The movable sleeve 23 is sleeved on the outer periphery of the sewage discharge pipe 21, and the length and position of the movable sleeve 23 correspond to the through cavity 29.

[0028] Specifically, when the filter plate 2 is rotated through the sewage discharge pipe 21, the upper surface of the filter plate 2 is continuously aligned with the lower end of the return flow frame 26. When the two are aligned, the flow direction of the sewage at the joint of the two is reversed, and the impurities on the surface of the filter plate 2 at the alignment position can be pushed upward into the return flow frame 26. Then, through the guide cavity 25, the sewage discharge pipe 21, and the outer conduit 22, the impurities can be discharged outward, thus facilitating the collection of the impurities.

[0029] As a further description of the above technical solution: a connecting seat 31 is rotatably installed at the upper end of the inner cavity of the tank body 1. The sewage discharge pipe 21 is arranged in the middle of the connecting seat 31. A limiting chute 35 is formed on the inner wall of the connecting seat 31. A limiting slider 34 that is slidably connected with the limiting chute 35 is fixedly installed on the inner wall of the connecting seat 31. A motor 3 is fixedly installed at the upper end of the outer side of the tank body 1. A driven gear ring 32 is fixedly installed on the outer periphery of the connecting seat 31.

Through the meshing connection between the driven gear ring 32 and the driving gear 33 and the sliding connection between the limiting slider 34 and the limiting chute 35, the motor 3 can drive the sewage discharge pipe 21 to rotate through its output shaft.

[0031] As a further description of the above technical solution: a first annular rotating groove 201 is formed in the inner wall on the upper side of the filter plate 2, a second annular rotating groove 211 is formed around the sewage discharge pipe 21, a return flow frame 26 is arranged around the sewage discharge pipe 21, a second annular rotating block 212 rotatably connected to the second annular rotating groove 211 is fixedly installed in the middle of the return flow frame 26, a first annular rotating block 202 rotatably connected to the first annular rotating groove 201 is fixedly installed around the return flow frame 26, a positioning tooth block 37 is fixedly installed on the inner wall of the tank body 1, and a movable tooth block 36 is fixedly installed at the lower end of the filter plate 2. The positioning tooth block 37 and the movable tooth block 36 are engaged with each other. A first socket 27 communicating with its inner cavity is fixedly installed at the upper end of the return flow frame 26, and a second socket 28 communicating with the guide cavity 25 is fixedly installed at the lower end of the positioning rod 24. The first socket 27 and the second socket 28 are inserted into each other.

[0032] Specifically, through the rotational connection between the second annular rotating groove 211 and the second annular rotating block 212 and between the first annular rotating block 202 and the first annular rotating groove 201, the movement direction of the filter plate 2 can be restricted around the return flow frame 26.

[0033] Through the clamping cooperation between the positioning tooth block 37 and the movable tooth block 36, the rotating filter plate 2 can move up and down continuously, thereby accelerating the separation efficiency of the filter plate 2 and the impurities above it and improving the treatment efficiency of the impurities.

[0034] Through the insertion connection between the first socket 27 and the second socket 28, the sleeved connection between the through cavity 29 and the movable sleeve 23, and the sliding connection between the limit slider 34 and the limit chute 35, a vertical movement space for the filter plate 2 is provided. And through the cooperation between the first socket 27 and the second socket 28 and between the through cavity 29 and the movable sleeve 23, when the filter plate 2 moves up and down, the guide cavity 25 can still communicate with the return flow frame 26 and the inner cavity of the sewage discharge pipe 21, so that the sewage can be guided into the outer conduit 22.
