[0002] Existing ultrafiltration membranes are microporous filtration membranes with uniform pore size specifications and a rated pore size range of 0.001-0.02 micrometers. By applying appropriate pressure to one side of the membrane, solute molecules smaller than the pore size can be screened out, thus separating particles with a molecular weight greater than 500 Daltons and a particle size greater than 2-20 nanometers. Ultrafiltration technology can be used to separate industrial wastewater, and has a good removal effect on organic matter and colloidal particles.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figures 1 to 3 This utility model provides a technical solution: an ultrafiltration membrane cleaning device, including a cleaning tank 4, and an installation frame 23 slidably connected to the cleaning tank 4 above it. Figure 1 As shown, supports 2 are symmetrically connected on both sides of the cleaning tank 4. The length of the supports 2 is greater than the width of the cleaning tank 4. To improve the stability of the supports 2, a leg 24 is vertically connected to the bottom of one end of the supports 2. The top of the two supports 2 is connected to a linear module 1 and a guide rail 3, respectively. Support seats 21 are connected to the bottom of both ends of the mounting frame 23. The two support seats 21 are slidably connected to the linear module 1 and the guide rail 3 through a slider. Under the drive of the linear module 1, the mounting frame 23 can be pushed to slide horizontally on the top of the cleaning tank 4, which makes it convenient for the staff to place the ultrafiltration membrane that needs to be cleaned on the mounting frame 23.

[0021] Meanwhile, to facilitate the loading and unloading of ultrafiltration membranes by users, U-shaped frames 8 with downward-facing openings are connected to the top of both support bases 21, and through slots 6 are opened on the mounting frame 23. The two ends of the U-shaped frames 8 pass through the through slots 6. A telescopic mechanism 7 is vertically connected between the mounting frame 23 and the support bases 21. The telescopic mechanism 7 is one of an electric telescopic rod, a hydraulic cylinder, or a pneumatic cylinder. By pushing the telescopic mechanism 7, the mounting frame 23 can be driven to slide vertically. After the mounting frame 23 is slid from the top of the cleaning tank 4 to one side, the mounting frame 23 is then controlled to slide downwards, making it convenient for staff to place the ultrafiltration membrane on top of the mounting frame 23. After installation, the mounting frame 23 is controlled to return to its initial position, allowing the ultrafiltration membrane to move into the cleaning tank 4 for rapid cleaning.

[0022] like Figure 1 ,2 As shown, to achieve batch cleaning of ultrafiltration membranes, multiple horizontal plates 9 are equidistantly arranged inside the mounting frame 23. Multiple second through grooves 11 are opened on each horizontal plate 9. A first through groove 10 is coaxially opened on the top of the second through groove 11. The diameter of the first through groove 10 is larger than the diameter of the second through groove 11. During installation, the ultrafiltration membrane to be cleaned is installed in the first through groove 10 and the second through groove 11. Since the first through groove 10 and the second through groove 11 have a stepped structure, the ultrafiltration membrane can be placed stably. In actual use, a first connecting pipe 14 is provided directly above each horizontal plate 9. Multiple telescopic pipes 13 are connected to the bottom of the first connecting pipe 14. The liquid outlet end of the telescopic pipe 13 is fixedly connected to a pipe connector 12. The pipe connector 12 is connected to the waste outlet of the ultrafiltration membrane, so that the cleaning solution can be transported to the inside of the ultrafiltration membrane to clean the accumulated impurities.

[0023] In summary, when using this ultrafiltration membrane cleaning device, the telescopic tube 13 is located directly above the first through groove 10, connecting multiple first connecting tubes 14 and second connecting tubes 15. Furthermore, this invention also includes a material tank 22, which holds a mixture of pickling solution and water. The end of the second connecting tube 15 is connected to the first pump body 16, connecting the inlet end of the first pump body 16 to the material tank 22. The first pump body 16 transports the cleaning solution from the material tank 22 to the telescopic tube 13, thus cleaning the impurities inside the ultrafiltration membrane. Simultaneously, an ultrasonic generator 5 is installed in the cleaning tank 4, which effectively improves the cleaning efficiency of the ultrafiltration membrane located in the cleaning tank 4 under the action of the ultrasonic generator 5.

[0024] To facilitate the transportation of cleaning solution within the cleaning tank 4 and the discharge of wastewater after cleaning, an inlet pipe 18 and a drain pipe 19 are connected to the outer wall of the cleaning tank 4, respectively. A second pump body 17 is connected to the end of the inlet pipe 18 and is connected to the material tank 22. The cleaning solution in the material tank 22 is transported to the cleaning tank 4 through the second pump body 17, allowing the cleaning solution to soak the ultrafiltration membrane. To prevent overflow due to high liquid level, a level gauge 20 is fixedly connected to the inner wall of the cleaning tank 4. Solenoid valves are connected to the inlet pipe 18, the drain pipe 19, the first connecting pipe 14, and the second connecting pipe 15, effectively controlling the transportation of the cleaning solution and greatly facilitating cleaning.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
