Description

Technical Field

[0001] This utility model relates to the field of thin film stretching technology, and in particular to a stretching device for ultrafiltration membrane production. Background Technology

[0002] Ultrafiltration membranes are a physical separation membrane technology based on pressure difference. Through the principle of microporous sieving, they achieve precise separation of substances with different molecular weights in a solution. Their pore size typically ranges from 0.001 to 0.1 micrometers, effectively retaining large molecules while allowing small molecules to pass through. This technology is widely used in water treatment, food processing, pharmaceuticals, and many other fields. Ultrafiltration membrane materials are mostly made of high-molecular polymers, possessing excellent properties such as acid and alkali resistance and high-temperature resistance. They can operate at room temperature without the need for chemical reagents, offering the dual advantages of high efficiency, energy saving, and environmental friendliness.

[0003] Chinese patent publication number CN208896482U discloses an ultrafiltration membrane stretching device, including a base. A worktable is fixedly connected to the top of the base. First bearing seats are installed on both sides of the upper surface of the worktable. A hydraulic cylinder is fixedly connected to the top of each first bearing seat. A cavity is formed inside the base, and a heating wire is installed inside the cavity. A suction pipe is inserted into the cavity and connected to a suction pump. The outlet of the suction pump is connected to an outlet pipe. Two sets of pipes are connected to one side of the outlet pipe, and jet nozzles are connected to one side of each set of pipes. A driving device is provided at one end of the first roller. The ultrafiltration membrane is passed between the two sets of first and second rollers. The hydraulic cylinder drives the second roller to compress the ultrafiltration membrane. A servo motor drives the first and second rollers to rotate, simultaneously compressing and stretching the ultrafiltration membrane, thus improving the stretching efficiency of the ultrafiltration membrane.

[0004] Existing ultrafiltration membrane stretching devices wind up the ultrafiltration membrane immediately after heating and stretching. At this point, the ultrafiltration membrane is at a high temperature and has high plasticity, making it prone to deformation during winding. This process avoids deformation or collapse caused by thermal stress, which can lead to uneven porosity on the ultrafiltration membrane. To overcome these disadvantages, this invention provides a stretching device for ultrafiltration membrane production. Utility Model Content

[0024] like Figure 1-3 As shown, the clamping assembly includes a gantry frame 23 fixedly connected to both sides of the first wave clamp 22. A hydraulic cylinder 24 is fixedly connected to the top of the gantry frame 23.

[0025] like Figure 1-3 As shown, the cooling assembly includes a cooling chamber 17 fixedly connected to the second slot 16. Several fan ports 18 are opened at the top of the cooling chamber 17, and cooling fans 19 are fixedly connected to the fan ports 18. Coolers 20 are fixedly connected to both sides inside the cooling chamber 17.

After cooling is completed, the first servo motor 5 starts to wind up the ultrafiltration membrane.
