An ultrafiltration membrane 4 is inserted into the inner cavity of the cleaning cylinder 2.

[0023] The inner wall of the cleaning cylinder 2 is provided with a chute 5, in which a slider 6 is slidably installed, a connecting frame 7 is installed on the side wall of the slider 6, and a roller 8 is rotatably installed on the outer side of the connecting frame 7, and the roller 8 can fit the side wall of the ultrafiltration membrane 4;

[0024] The inner side wall of the lower end of the cleaning cylinder 2 is provided with an internal thread. A block 9 is installed on the lower end of the cleaning cylinder 2 by screwing the thread. A solenoid valve 10 is installed on the side wall of the block 9. The solenoid valve 10 is electrically connected to an external power supply. The input end of the solenoid valve 10 passes through the side wall of the block 9 and is connected to the inner cavity of the cleaning cylinder 2. The output end of the solenoid valve 10 is installed with a drain pipe 11.

[0025] In this technical solution, the ultrafiltration membrane 4 proposed herein is an ultrafiltration membrane core pulled out from a tubular ultrafiltration membrane, which is composed of a sleeve and a plurality of hollow fiber tubes. When it needs to be cleaned, it can be directly placed in the cleaning barrel 2, and then a cleaning liquid is injected into the cleaning barrel 2 through the water inlet pipe 13. The cleaning liquid can be tap water or pure water, and then the cleaning barrel 2 is driven to rotate by the connecting rod 3, so that the cleaning liquid inside the cleaning barrel 2 continuously rolls in the cleaning barrel 2, fully contacts the hollow fiber tubes of the ultrafiltration membrane 4, and washes away the stains on the outside thereof;

[0026] By arranging the electromagnetic valve 10 below the blocking block 9, after cleaning is completed, when drainage is required, the electromagnetic valve 10 can be directly controlled to open to discharge the waste water in the cleaning cylinder 2.

[0027] In some technical solutions, a fixed cylinder 12 is inserted into the side wall of the cleaning cylinder 2, and a water inlet pipe 13 is inserted into the fixed cylinder 12. One end of the water inlet pipe 13 can be inserted into the cleaning cylinder 2 through the fixed cylinder 12, and the other end of the water inlet pipe 13 is connected to an external water supply device.

[0028] In this technical solution, a sealing ring is provided on the inner wall of the fixed cylinder 12 , and the sealing ring can fit with the side wall of the water inlet pipe 13 , thereby ensuring that the cleaning liquid entering the cleaning cylinder 2 will not leak out of the fixed cylinder 12 .

[0029] In some technical solutions, the frame 1 includes a side panel 101, a first curved water baffle 102 and a second curved water baffle 103. The side wall of the side panel 101 is installed with the first curved water baffle 102, and the side wall of the first curved water baffle 102 is hinged with the second curved water baffle 103. The first curved water baffle 102 and the second curved water baffle 103 can be spliced ​​into a ring shape, and the connecting rod 3 is rotatably installed on the side panel 101.

[0030] In this technical solution, the arrangement of the first arc-shaped water baffle 102 and the second arc-shaped water baffle 103 can intercept the cleaning liquid thrown out during the rotation of the cleaning drum 2;

[0031] At the same time, the second arc-shaped plate 103 is rotatable, thereby facilitating the loading and unloading of the ultrafiltration membrane 4 .

[0032] In some technical solutions, a counterweight 14 is installed on the side wall of the slider 6 , and a protrusion 15 is installed on the outer side wall of the drum 8 , and the protrusion 15 can fit with the side wall of the ultrafiltration membrane 4 .

[0033] In this technical solution, during the rotation of the cleaning drum 2, the slider 6 will move the roller 8 up and down continuously under the action of gravity, so that the roller 8 squeezes and rubs the ultrafiltration membrane 4, so that the hollow fiber tubes in the ultrafiltration membrane 4 can rub against each other, thereby removing stubborn stains and improving the cleaning effect.

[0034] In some technical solutions, a drive motor 16 is installed on the side wall of the side panel 101 , the drive motor 16 is electrically connected to an external power source, and an output end of the drive motor 16 passes through the side wall of the side panel 101 and is connected to the connecting rod 3 .

[0035] In some technical solutions, one end of a bracket 17 is installed on the side wall of the frame 1 , and a connecting ring 18 is installed on the other end of the bracket 17 . The connecting ring 18 is sleeved on the outside of the water inlet pipe 13 .

[0036] In this technical solution, the arrangement of the connecting ring 19 and the bracket 17 can support the water inlet pipe 13 .

[0037] Working principle: When the ultrafiltration membrane 4 needs to be cleaned, the ultrafiltration membrane 4 can be directly placed in the cleaning cylinder 2, and then the cleaning liquid is injected into the cleaning cylinder 2 through the water inlet pipe 13, and then the connecting rod 3 is driven to rotate by the driving motor 16. The connecting rod 3 drives the cleaning cylinder 2 to rotate, so that the cleaning liquid inside it continuously rolls in the cleaning cylinder 2, fully contacts the hollow fiber tube of the ultrafiltration membrane 4, and washes away the stains on its outside. At the same time, the slider 6 will move the roller 8 up and down continuously under the action of gravity, so that the roller 8 squeezes and rubs the ultrafiltration membrane 4, so that the hollow fiber tubes in the ultrafiltration membrane 4 can rub against each other, thereby removing stubborn stains.

[0038] When drainage is required, the solenoid valve 10 can be directly controlled to open to discharge the waste water in the cleaning cylinder 2;

[0039] After the discharge is completed, close the solenoid valve 10, and inject water into the cleaning cylinder 2 through the water inlet pipe 13 again to clean the ultrafiltration membrane 4 for the second time. Then open the solenoid valve 10 and release water again, then the ultrafiltration membrane 4 can be taken out to complete the membrane washing operation of the ultrafiltration membrane 4.
