Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] As shown in Figure 1 - Figure 4 The present embodiment provides a technical solution: a constant-flow water-producing MBR membrane reaction tank device, comprising:

[0029] The reaction tank body 1 is fixedly connected with the MBR membrane body 4 at the top end of the inner wall of the reaction tank body 1.

[0030] The cleaning assembly 2 comprises a motor 21 fixedly connected to the outside of the reaction tank body 1, a transmission belt 22 fixedly connected to the driving end of the motor 21, a transmission wheel 23 fixedly connected to one end of the transmission belt 22 away from the motor 21, the transmission wheel 23 being rotatably connected to the outside of the reaction tank body 1, a screw rod 24 fixedly connected to one end of the transmission wheel 23 close to the reaction tank body 1, the screw rod 24 being rotatably connected to the inside of the reaction tank body 1 at one end away from the motor 21, a scraper 25 threadedly connected to the outside of the screw rod 24, the scraper 25 being slidably connected to the inside of the reaction tank body 1, a limiting rod 26 fixedly connected to the inside of the reaction tank body 1, and the scraper 25 being slidably connected to the outside of the limiting rod 26 in the inside of the scraper 25.

[0031] The reaction pool body 1 provides a closed reaction space, so that the organic matter in the sewage can be effectively degraded by microorganisms, the MBR membrane body 4 is used for realizing mud-water separation, filtering out the suspended matter and microorganisms in the water, and ensuring the water quality, the motor 21 is a power source of the cleaning assembly 2, drives the transmission belt 22 to operate, the transmission belt 22 transmits the power of the motor 21 to the transmission wheel 23, the transmission belt 22 serves as a medium for power transmission, ensures the effective transmission of the power, and enables the cleaning assembly 2 to operate stably, the screw rod 24 moves the scraper 25 in the reaction pool body 1 through rotary motion, the scraper 25 directly slides with the inner wall of the reaction pool body 1, so that the impurities attached to the inner wall of the reaction pool body 1 are cleaned during the movement, and the limiting rod 26 ensures that the scraper 25 does not deviate from the predetermined track during the cleaning process

[0032] The flushing assembly 3 comprises a winding barrel 31, the outer side of the winding barrel 31 is rotationally connected to the outer side of the reaction pool body 1, the transmission wheel 23 is fixedly connected to the winding barrel 31 away from the reaction pool body 1, one end of the winding barrel 31 is fixedly connected with a water supply pipe 32, one end of the water supply pipe 32 away from the winding barrel 31 is fixedly connected with a water spraying pipe 33, one end of the water spraying pipe 33 away from the scraper 25 is fixedly connected with a water spraying head 34, one end of the scraper 25 is fixedly connected with a fixed block 35, and the inside of the fixed block 35 is fixedly connected to the outside of the water spraying pipe 33;

[0033] The main responsibility of the winding barrel 31 is to wind the water supply pipe 32, and the water supply pipe 32 is connected with the water spraying pipe 33 through the inner wall of the reaction pool body 1, which ensures that the flushing water can be continuously supplied from the outside to the water spraying pipe 33. In order to ensure the sealing of the whole device, a sealing ring is installed at the connection between the water supply pipe 32 and the reaction pool body 1 when the water supply pipe 32 is installed, which can effectively prevent the leakage phenomenon. The water spraying pipe 33 is used for accurately delivering the flushing water to the surface of the MBR membrane body 4 that needs to be cleaned, which improves the flushing efficiency and cleaning effect. The design of the water spraying head 34 can spray the flushing water to the membrane surface at a certain pressure and angle, so as to effectively remove the dirt and biofilm on the membrane surface, and maintain the cleanliness and permeability of the membrane. The design of the fixed block 35 ensures that the water spraying pipe 33 can be fixed on the scraper 25 of the reaction pool body 1 even under the action of the internal water pressure, which ensures the stability of the whole system.

[0034] Working principle:

[0035] As shown in Figure 1 - Figure 4 ,

[0036] In use: when the inner wall of the reaction pool body 1 needs to be cleaned, first start the motor 21, the drive of the motor 21 makes the transmission belt 22 drive the transmission wheel 23 to rotate synchronously, at this time the lead screw 24 connected to the transmission wheel 23 will make the scraper 25 move linearly in one direction through threaded connection, so that the outer side of the scraper 25 cleans the inner wall of the reaction pool body 1, then during the cleaning process, the winch barrel 31 sends clean water to the water pipe 32, the winch barrel 31 will rotate synchronously during the movement of the scraper 25, when the scraper 25 moves in the other direction to the inside of the reaction pool body 1, the water pipe 32 on the winch barrel 31 will be loosened to avoid the water supply pipe 33 from being unable to get water supply during the movement, at this time when the water pressure is generated in the water supply pipe 33, the water head 34 will wash the surface of the MBR membrane body 4, and during the movement, the plurality of membrane groups in the MBR membrane body 4 will be washed, so that during the cleaning of the inner wall, the MBR membrane body 4 can also be washed at the same time, the service life of the MBR membrane body 4 is improved, after the washing is completed, the sewage and impurities are discharged through the waterproof port on the reaction pool body 1, and the cleaning is completed.
