[0030] In this embodiment, the screw rod 312 is rotatably connected through the bearing flushing device body 2, the first slider 314 is threadedly connected to the outer wall of the screw rod 312, and one end of the movable nozzle 319 is connected to the second conversion box 7. Through the cooperation of the screw rod 312, the first slider 314, the movable nozzle 319, and the limit rod 3110, the movable nozzle 319 connected between the first conversion box 6 and the second conversion box 7 can be reciprocated up and down on one side of the flushing device body 2, so that the spraying range of the aeration hole connected to one side of the movable nozzle 319 can be wider, and then the flushing operation can be performed on different positions of the membrane, thereby increasing the applicability of the device.

[0031] Furthermore, the end of the limiting rod 3110 away from the first conversion box 6 is fixedly connected to the second conversion box 7, and through the cooperation of the sliding rod 317 and the second sliding block 318, the first conversion box 6 can be made more stable during the movement.

[0033] Example 2

[0034] Based on Example 1, a preferred embodiment of a membrane bioreactor aeration and flushing device provided by the utility model is as follows: Figures 1 to 4 As shown: the disassembly and assembly mechanism 32 includes a positioning groove 321 opened on one side of the first conversion box 6, a positioning block 322 is provided on the inner wall of the positioning groove 321, a clamping groove 323 is opened on one side of the positioning block 322, an inner groove 324 is opened inside one side of the first conversion box 6, a mounting block 325 is slidably connected to the inner wall of the inner groove 324, a clamping rod 326 is fixedly connected to the inner side of the mounting block 325, a connecting rod 327 is movably connected to one side of the first conversion box 6, a spring 328 is fixedly connected to the inner wall of the inner groove 324, the outer end of the connecting rod 327 is rotatably connected to a rotating rod 329 through a bearing, a positioning rod 3210 is fixedly connected to the inner side of the rotating rod 329, and a positioning hole 3211 is opened on the inner side of the first conversion box 6.

[0035] In this embodiment, the positioning block 322 is fixedly connected to the second slider 318, the clamping rod 326 movably penetrates the first conversion box 6 and is clamped with the clamping groove 323, one end of the spring 328 is fixedly connected to the mounting block 325, and the inner end of the connecting rod 327 is fixedly connected to the mounting block 325. Through the cooperation of the positioning block 322, the positioning groove 321, the clamping groove 323, the mounting block 325, the clamping rod 326, the spring 328, the connecting rod 327, and the rotating rod 329, it is convenient to manually disassemble the first conversion box 6 and the second conversion box 7, so as to facilitate manual cleaning of the aeration holes opened on one side of the movable nozzle 319, which can prevent the aeration holes from being blocked and affecting the normal use of the device.

[0036] Furthermore, there are two positioning blocks 322, which are symmetrically distributed in the first conversion box 6 and the second conversion box 7, and the positioning block 322 on the right is fixedly connected to the first slider 314, and the positioning rod 3210 is slidably connected in the positioning hole 3211. Through the cooperation of the positioning rod 3210, the positioning hole 3211, and the rotating rod 329, the clamping rod 326 can stay at a position away from the clamping groove 323, thereby freeing up manual hands and making it easier for manual disassembly and assembly of the first conversion box 6 and the second conversion box 7.

[0037] When the first conversion box 6 and the second conversion box 7 need to be disassembled, the rotating rod 329 is first pulled outward manually, so that the connecting rod 327 can drive the mounting block 325 to move outward, and then the clamping rod 326 fixedly connected to one side of the mounting block 325 can move outward. At the same time, when the rotating rod 329 moves outward, the positioning rod 3210 can be moved outward synchronously. When the positioning rod 3210 is separated from the positioning hole 3211, the clamping rod 326 and the clamping groove 323 are in a separated state first, and then the rotating rod 329 is manually rotated. Rod 329 makes the inner end of the positioning rod 3210 press against the outer wall of the first conversion box 6, thereby having a limiting effect, and then the clamping rod 326 can stay in a position away from the clamping groove 323, freeing up the hands of the operator, without having to support the rotating rod 329 all the time, and then repeating this operation to disassemble the second conversion box 7, thereby disassembling the first conversion box 6 and the second conversion box 7, so as to facilitate manual cleaning of the aeration holes opened on one side of the movable nozzle 319, and prevent the aeration holes from being blocked and affecting the normal use of the device.
