Description

Technical Field

[0001] This utility model belongs to the field of cooling tank technology, specifically relating to a plastic curing cooling tank for ultrafiltration membrane production. Background Technology

[0002] Ultrafiltration membranes are commonly used separation membranes, widely applied in water treatment, food and beverage, biomedicine, and environmental engineering. They can separate solutes and solvents through screening, offering advantages such as high efficiency, low energy consumption, and environmental friendliness. In the production process of ultrafiltration membranes, a mixed solution is uniformly coated onto a flat membrane roll using a specific coating device. The coated membrane roll then undergoes a plastic curing and cooling process to enhance the membrane's mechanical properties.

[0003] Chinese patent application CN202322421545.7 mentions a plastic curing and cooling tank for ultrafiltration membrane production. The cooling tank is equipped with multiple guide rollers to form a guide roller group, which facilitates the serpentine movement of the membrane roll in the cooling tank body, increases the contact area between the membrane roll and the coolant in the cooling tank body, and thus improves the curing and cooling effect. However, the guide rollers installed in the cooling tank are fixed and the distance between two adjacent guide rollers in the vertical direction cannot be adjusted, so the tension of the guide roller group on the membrane roll cannot be adjusted. In addition, the guide rollers are solid structures, and the membrane roll that is in contact with the guide rollers is not easy to cure and cool, which affects the curing and cooling effect. Utility Model Content

[0004] The purpose of this utility model is to provide a plastic curing and cooling tank for ultrafiltration membrane production, so as to solve the problems mentioned in the background art, such as the inability to adjust the distance between two adjacent guide rollers in the vertical direction, the inability to adjust the tension of the guide roller group on the membrane roll, and the solid structure of the guide rollers, which makes it difficult for the membrane roll attached to the guide rollers to cure and cool, thus affecting the curing and cooling effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic curing and cooling tank for ultrafiltration membrane production, comprising a cooling tank body, wherein a guide roller assembly is movably installed within the cooling tank body, the guide roller assembly comprising a plurality of first guide rollers and a plurality of second guide rollers, the plurality of first guide rollers comprising an outer roller, an inner roller, a connecting plate and an agitating plate, the inner roller being located inside the outer roller, the connecting plate being connected between the outer roller and the inner roller, the agitating plate being evenly distributed on the outer surface of the inner roller, and the plurality of second guide rollers having the same structure as the plurality of first guide rollers.

[0006] Preferably, the outer surface of the outer roller has through holes distributed at equal intervals.

[0007] Preferably, a lead screw corresponding to the guide roller assembly is installed on the inner side wall of the cooling tank body, and a lead screw sleeve is fitted on the lead screw, and a handle is connected to the input end of the lead screw.

[0008] Preferably, the inner sidewall of the cooling tank body is provided with a sliding groove corresponding to the lead screw, and a slider is slidably connected inside the sliding groove.

[0009] Preferably, both ends of the first guide roller and the second guide roller are rotatably connected to rotating shafts, and the other ends of the two rotating shafts are respectively connected to the lead screw sleeve and the slider.

[0010] Preferably, a film roll is laid on the guide roller assembly, and the film roll is in contact with the coolant in the cooling tank body.

[0011] Preferably, a dust removal mechanism and a drying mechanism are respectively installed on opposite sides of the cooling tank body, and the free end of the membrane roll enters the cooling tank body through the dust removal mechanism and exits the cooling tank body through the drying mechanism.

[0012] Preferably, fixed guide rollers are rotatably connected to the inner side wall of the cooling tank body near the dust removal mechanism and the drying mechanism.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The guide roller of this utility model is composed of an inner roller and an outer roller. Cooling liquid can enter between the inner roller and the outer roller. At the same time, the outer roller is provided with through holes, so that the film roll that is in contact with the outer roller can also directly contact the cooling liquid, which improves the curing cooling effect. In addition, an agitator is provided on the outer side wall of the inner roller. When the film roll moves and drives the guide roller to rotate, it can drive the agitator to rotate, thereby agitating the cooling liquid and further improving the curing cooling effect.

When the film roll 10 moves and drives the first guide roller 2 and the second guide roller 3 to rotate, it can drive the stirring plate 24 to rotate, thereby stirring the coolant and further improving the curing cooling effect.

[0026] In the above technical solution, the handle 7 is rotated to drive the lead screw 5 to rotate, and the lead screw 5 rotates to drive the lead screw sleeve 6 to move up and down, thereby driving the first guide roller 2 and the second guide roller 3 to move up and down, thereby adjusting the distance between two adjacent guide rollers in the vertical direction, and thus adjusting the tension of the guide roller group on the film roll 10.

[0027] like Figure 1 As shown, a film roll 10 is placed on the guide roller assembly, and the film roll 10 is in contact with the coolant in the cooling tank body 1, so that the film roll 10 is cured and cooled by the coolant.

[0028] Dust removal mechanism 11 and drying mechanism 12 are respectively installed on opposite sides of the cooling tank body 1. The free end of the membrane roll 10 passes through the dust removal mechanism 11 into the cooling tank body 1 and passes through the drying mechanism 12 out of the cooling tank body 1.
