[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1-4 As shown, the embodiment of the present invention proposes an MBR curtain membrane device with enhanced cleaning, comprising:

[0023] A cleaning tank 1 is provided with a cleaning liquid; a drain pipe 5 is provided on the cleaning tank 1, and a valve is provided on the drain pipe 5. The cleaning liquid in the cleaning tank 1 can be discharged through the drain pipe 5 by opening the valve;

[0024] Cleaning assembly; the cleaning assembly includes a motor 2 fixed on the cleaning box 1, the output end of the motor 2 is fixedly connected to the shaft 11, the shaft 11 is rotatably connected to the inner wall of the cleaning box 1, three fixed T-shaped rods 8 are fixed on the shaft 11, and a positioning sleeve 12 is slidably connected to the shaft 11. A threaded bolt 14 is passed through the sleeve 12, and the bolt 14 is against the outer wall of the shaft 11.

[0025] Three mobile T-shaped rods 7 are fixedly connected to the sliding sleeve 12. The mobile T-shaped rod 7 and the fixed T-shaped rod 8 are arranged opposite to each other. Two rubber sleeves 13 are fixed on the mobile T-shaped rod 7 and the fixed T-shaped rod 8. The pipe ends at both ends of the MBR curtain membrane are sleeved into the rubber sleeves 13 on the mobile T-shaped rod 7 and the fixed T-shaped rod 8. After the installation is completed, the staff manually moves the mobile T-shaped rod 7 to drive the sliding sleeve 12 to move on the shaft rod 11 until the MBR curtain membrane is tightened, and then tightens the bolts 14 to make it against the shaft rod 11. In this way, the mobile T-shaped rod 7 and the sliding sleeve 12 can be positioned, and the MBR curtain membrane is also tightened.

[0026] The starting motor 2 drives the shaft 11 to rotate, thereby driving the movable T-bar 7 and the fixed T-bar 8 to rotate, thereby realizing the rotation of the MBR curtain membrane. The MBR curtain membrane continuously rotates in the cleaning liquid and moves relative to the cleaning liquid, thereby realizing the cleaning of the MBR curtain membrane; when the MBR curtain membrane rotates to the upper side, the MBR curtain membrane is separated from the cleaning liquid.

[0027] It also includes a spray cleaning mechanism, which includes a mounting frame 6 mounted on the cleaning box 1, a spray pipe 9 mounted on the mounting frame 6, and a plurality of spray holes 10 provided on the spray pipe 9. A water pump 3 is mounted on the cleaning box 1, and a water inlet pipe is mounted on the water inlet end of the water pump 3, and the water inlet pipe is connected to the cleaning box 1. A delivery pipe 4 is mounted on the water outlet end of the water pump 3, and the delivery pipe 4 is connected to the spray pipe 9.

[0028] When the MBR curtain membrane rotates to the upper side, the MBR curtain membrane is separated from the cleaning liquid, and the water pump 3 works to transport the cleaning liquid through the delivery pipe 4 to the spray pipe 9, and finally sprays it out through the spray hole 10, so that the MBR curtain membrane can be cleaned again, thereby improving the cleaning effect of the MBR curtain membrane;

[0029] After cleaning is completed, the rubber sleeve 13 is bent and separated from the MBR curtain membrane, and the cleaned MBR curtain membrane can be removed. The operation is simple and convenient.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
