[0001] The utility model belongs to the technical field of aerated biological filter pools, and in particular relates to an aerated biological filter pool which is convenient for cleaning a filter screen. Background Art

[0002] Aerated biological filter, referred to as BAF, is a new type of biofilm sewage treatment process developed in Europe and the United States in the late 1980s. It was greatly developed in the early 1990s, with the largest scale reaching hundreds of thousands of tons per day, and it has been developed to remove nitrogen and phosphorus. When filtering sewage, the sewage will first pass through the pretreatment device on the aerated biological filter, so that the filter net in the pretreatment device will filter the solid waste in the sewage to prevent the waste from entering the filter tank. Publication number: CN219689480U, involving an aerated biological filter, including a filter tank body and a top cover, wherein the filter tank body is provided with a water inlet pipe, a water distribution pipe, a supporting layer and a filter material layer from bottom to top, below the water distribution pipe and between the supporting layer and the filter material Aeration pipes are respectively arranged between the layers, a rotating frame which can rotate horizontally is arranged in the filter tank body, the central rotating shaft of the rotating frame is drivingly connected with the driving member, and the filter material layer is arranged on the rotating frame; a flow stabilizing plate with a grid is arranged at the drain outlet of the filter tank body, a filter water tank is arranged on the outer wall of the filter tank body below the drain outlet, a partition is arranged in the filter water tank, the bottom of the cavity on the side away from the filter tank body in the filter water tank is connected with the outlet pipe, and the bottom of the cavity on the side close to the filter tank body in the filter water tank is connected with the backwash outlet pipe. By adding a rotating frame, the aerated biological filter tank can intermittently rotate the filter material layer, increase the impact force of the flushing water flow, and effectively prevent the filter holes on the filter plate from being blocked.

[0003] However, there are some problems with the prior art: after the existing filter has been used for a certain period of time, in order to prevent it from affecting the flow of subsequent sewage, the garbage on the surface of the filter needs to be cleaned, but the filter is mostly fixed in the treatment box by bolts, so when the garbage on the filter needs to be cleaned, it needs to be disassembled and removed from the treatment box, which results in a relatively cumbersome operation process. Therefore, we propose an aerated biological filter tank that is easy to clean the filter. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide an aerated biological filter tank which is easy to clean the filter screen. The moving part is driven to move upward by the operation of the moving component. The upward movement of the moving part drives the first connecting plate to move upward. The upward movement of the first connecting plate drives the filter screen to move upward, thereby moving the filter screen out of the treatment box. After the filter screen is moved out of the treatment box, the garbage on the filter screen can be cleaned, thereby achieving the advantage of facilitating the cleaning of the garbage on the filter screen.

[0031] The sewage enters the water inlet mechanism 2, and then the water is discharged into the treatment box 301 by the water inlet mechanism 2. The garbage in the sewage is filtered out by the filter 302 in the treatment box 301, and then the sewage in the treatment box 301 is discharged into the filter pool 1 through the drainage pipe below the treatment box 301. The impurities in the sewage are filtered out by the filter pool 1, so that the sewage is purified. When it is necessary to clean the garbage on the filter 302, the moving part is driven to move upward by the movement of the moving component 4, and the upward movement of the moving part drives the first connecting plate 5 to move upward. The first connecting plate 5 moves upward and drives the filter screen 302 to move upward, so that the filter screen 302 is moved out of the processing box 301. After the filter screen 302 is moved out of the processing box 301, the garbage on the filter screen 302 can be cleaned, so that the garbage on the filter screen 302 is easily cleaned. When the filter screen 302 moves upward, it also drives the second connecting plate 6 to move. When the second connecting plate 6 moves, the guide mechanism 7 guides it to prevent the filter screen 302 from rotating after the filter screen 302 is moved out of the processing box 301.

[0032] Specifically, the moving component 4 includes a mounting frame 401, in which a motor 402 is fixedly installed, and one end of the mounting frame 401 is fixedly installed on one end of the processing box 301; a first gear 403 is fixedly installed on the output shaft end of the motor 402, and the first gear 403 is meshed with a second gear 404; a first mounting plate 8 is fixedly installed on one end of the processing box 301, and a first mounting hole is opened on the first mounting plate 8, and a bearing 9 is fixedly installed in the first mounting hole; a second mounting hole is opened on the second gear 404, and a threaded sleeve 405 is fixed in the second mounting hole, and the upper end of the threaded sleeve 405 is rotatably set in the bearing 9; a threaded rod 406 is rotatably set in the threaded sleeve 405, and the lower surface of the protruding end of the first connecting plate 5 is fixedly installed on the upper surface of the threaded rod 406.
