Description

Technical Field

[0001] This invention relates to the field of polytetrafluoroethylene hollow fiber membrane filament modification technology, and in particular to a continuous hydrophilic modification device for polytetrafluoroethylene hollow fiber membrane filaments. Background Technology

[0002] Polytetrafluoroethylene (PTFE) hollow fiber membranes are superior to other membrane materials due to their excellent chemical resistance, high-temperature resistance, and good mechanical properties, making them suitable for treating highly polluted wastewater. However, the inherent strong hydrophobicity of PTFE membranes hinders their application in water treatment. Hydrophilicity is an inherent property of solid surfaces, determined by the synergistic effect of surface chemistry and surface geometry. Currently reported hydrophilic modification methods mainly include wet chemical methods, plasma treatment methods, radiation grafting methods, and surface coating methods.

[0003] Surface coating impregnation is widely used due to its simple and convenient operation and ease of removing surface contaminants. However, there are very few devices on the market currently suitable for continuous hydrophilic modification of polytetrafluoroethylene hollow fiber membranes; most are intermittent hydrophilic modifications, requiring multiple operations to achieve the desired effect. The improvements made to this tank mainly aim to achieve the following functions or solve the following technical problems: (1) For the existing hydrophilic modification equipment for polytetrafluoroethylene hollow fiber membrane filaments, multiple processes are required to complete the hydrophilic modification, which is cumbersome to operate and requires following fixed steps, resulting in low automation.

[0004] (2) When continuously hydrophilic modification of polytetrafluoroethylene hollow fiber membrane filaments, after the polytetrafluoroethylene hollow fiber membrane filaments are wetted by the hydrophilic modification solution, the surface of the polytetrafluoroethylene hollow fiber membrane filaments needs to be cleaned. Currently, the cleaning is done by passing the polytetrafluoroethylene hollow fiber membrane filaments through a cleaning tank. However, the water in the cleaning tank does not flow. After cleaning a lot, the subsequent cleaning of the polytetrafluoroethylene hollow fiber membrane filaments is incomplete. Summary of the Invention

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1 Reference Figures 1-7 This is the first embodiment of the present invention. This embodiment provides a continuous hydrophilic modification device for polytetrafluoroethylene hollow fiber membrane filaments, which includes a modification unit 100. The modification unit 100 includes a base 101 and an unwinding assembly 102, a winding assembly 103, a holding assembly 104, a support assembly 105, and a baking assembly 106 installed at both ends of the top of the base 101. The holding assembly 104 is located on one side of the unwinding assembly 102, the baking assembly 106 is located on one side of the winding assembly 103, and the support assembly 105 is disposed between the holding assembly 104 and the baking assembly 106. The modification unit 200 includes a cleaning unit 200, which includes a ring box 201 fixedly installed above the support assembly 105, a water supply pipe 202 fixed to the outer ring of the ring box 201, a plurality of water spraying assemblies 203 disposed in the inner ring of the ring box 201, and an adjusting assembly 204 rotating inside the ring box 201. The adjusting assembly 204 is used in conjunction with the water spraying assemblies 203.

[0033] In use, the winding assembly 103 can wind up the polytetrafluoroethylene hollow fiber membrane filaments and provide tension to them, enabling them to move continuously throughout the device. This process continuously modifies the polytetrafluoroethylene hollow fiber membrane filaments. After modification, the cleaning unit 200 cleans the filaments to remove any residual modification solution. The baking assembly 106 then dries the filaments. Finally, the motor 103d drives the second rotating rod 103b to rotate, completing the winding process.

[0034] Example 2 Reference Figure 1 , Figure 2 and Figure 8 This is the second embodiment of the present invention, which differs from the first embodiment in that it further includes an unwinding assembly 102, which includes a first support frame 102a fixed to the top of the base 101, a first rotating rod 102b rotating on the first support frame 102a, and an unwinding drum 102c sleeved on the first rotating rod 102b; the winding assembly 103 includes a second support frame 103a fixed to the top of the base 101, a second rotating rod 103b rotating on the second support frame 103a, and a winding drum 103c sleeved on the second rotating rod 103b. A motor 103d is fixedly installed on one side of the second support frame 103a, and the output end of the motor 103d is fixedly connected to one end of the second rotating rod 103b.

[0035] The rotation of motor 103d drives the second rotating rod 103b to rotate, thereby enabling the winding of the polytetrafluoroethylene hollow fiber membrane filaments by the take-up drum 103c. The unwinding drum 102c and the take-up drum 103c are used to wind the polytetrafluoroethylene hollow fiber membrane filaments. There is a certain friction between the unwinding drum 102c and the take-up drum 103c and the first rotating rod 102b and the second rotating rod 103b, respectively, which can ensure the stability of the unwinding drum 102c and the take-up drum 103c between the first rotating rod 102b and the second rotating rod 103b.

[0036] Specifically, the holding assembly 104 includes a plurality of holding boxes 104a continuously fixed to the top of the base 101. The top connection of the plurality of holding boxes 104a and the two sides after connection are rotatably connected to a second rotating roller 104c. A first rotating roller 104b is rotatably connected in the holding box 104a.

[0037] Furthermore, there are several options for the arrangement of the holding box 104a: First, the device has three consecutive holding boxes 104a along the direction from the unwinding assembly 102 to the winding assembly 103. The three holding boxes 104a respectively contain anhydrous ethanol, a PVA-PVP mixed solution (mass ratio 1:1, PVA mass concentration 0.5 wt%), a glutaraldehyde-hydrochloric acid solution (concentration ratio 10:1), and a GA concentration of 5%, and the traction speed of the motor 103d is 0.5 meters per minute. Second, the device has two consecutive holding boxes 104a along the direction from the unwinding assembly 102 to the winding assembly 103. In the first method, a hydrophilic monomer-ethanol mixed solution with a mass ratio of 1:9 and a monomer mass concentration of 0.5 wt% is placed in the container, along with a glutaraldehyde-hydrochloric acid solution with a concentration ratio of 10:1 and a GA concentration of 5%. The traction speed of motor 103d is 1.5 meters per minute. In the second method, a container 104a is set up in the device, containing a hydrophilic group-ethanol mixed solution with a mass ratio of 1:9 and a hydrophilic group mass concentration of 1 wt%, a glutaraldehyde-hydrochloric acid solution with a concentration ratio of 10:1 and a GA concentration of 5%. The traction speed of motor 103d is 3 meters per minute. All three methods can modify the polytetrafluoroethylene hollow fiber membrane filaments.

[0038] Specifically, the support assembly 105 includes a water tank 105a fixed to the top of the base 101, a drain pipe 105b fixed to one side of the water tank 105a, and two fixing plates 105c symmetrically fixed to the top of the water tank 105a. Two cleaning rollers 105d are rotatably connected between the two fixing plates 105c.

[0039] The two cleaning rollers 105d allow the PTFE hollow fiber membrane filaments to pass between them, enabling a transmission effect on their movement. Simultaneously, the soft bristles on the surfaces of the two cleaning rollers 105d clean the solution from the PTFE hollow fiber membrane filaments. Combined with the function of the cleaning unit 200, this results in a more thorough cleaning of the PTFE hollow fiber membrane filaments.

[0040] Specifically, the baking assembly 106 includes a baking oven 106a fixed to the top of the base 101, a placement slot 106b opened inside the baking oven 106a, two fixing brackets 106c symmetrically fixed in the placement slot 106b, and two baking plates 106d fixedly installed on opposite sides of the two fixing brackets 106c. The placement slot 106b is connected to the outside, and a plurality of third rotating rollers 106e are rotatably connected in the placement slot 106b. The plurality of third rotating rollers 106e are all arranged between the two baking plates 106d. The two baking plates 106d are electrically connected to an external power source.

[0041] The baking assembly 106 can dry the cleaned polytetrafluoroethylene hollow fiber membrane filaments. The baking plate 106d is waterproof and will not be affected by water. The baking plate 106d is an existing structure and will not be described in detail here.

[0042] In use, the polytetrafluoroethylene hollow fiber membrane filaments to be modified are first sleeved onto the first rotating rod 102b via the unwinding drum 102c, and one end of the polytetrafluoroethylene hollow fiber membrane filaments is then attached via an attachment... Figure 8 The membrane passes through the device and is fixed on the take-up drum 103c. Then, by turning on the motor 103d, the second rotating rod 103b is driven to rotate, which has a traction effect on the polytetrafluoroethylene hollow fiber membrane filaments, so that the polytetrafluoroethylene hollow fiber membrane filaments can be continuously hydrophilically modified.

[0043] Example 3 Reference Figures 3-11 This is the third embodiment of the present invention. This embodiment is based on the first two embodiments. This embodiment also includes a water spray assembly 203, which includes a nozzle 203a disposed in the inner ring of the ring box 201 and a control component 203b disposed inside the ring box 201. The nozzle 203a and the control component 203b are slidably engaged, and the control component 203b is slidably engaged with the adjustment assembly 204.

[0044] With the water supply pipe 202 in place, when water flows into the ring box 201 from the water supply pipe 202, it will form a circulating state in the ring box 201, which will drive the regulating component 204 to rotate and cooperate with the water spray component 203 to achieve large-scale cleaning and protection of polytetrafluoroethylene hollow fiber membrane filaments.

[0045] Specifically, the nozzle component 203a includes a fixed tube 203a-1 fixed to the inner ring of the ring box 201, a telescopic tube 203a-2 and a nozzle 203a-3 disposed at one end of the fixed tube 203a-1 away from the inner ring of the ring box 201, and L-shaped rods 203a-5 disposed on both sides of the fixed tube 203a-1. Sliding strips 203a-6 are symmetrically fixedly connected to the inner ring of the fixed tube 203a-1. The two ends of the telescopic tube 203a-2 are respectively fixed to one end of the fixed tube 203a-1 and one end of the nozzle 203a-3. A first transmission plate 203a-4 is fixedly connected to the inner ring of the nozzle 203a-3. One end of the L-shaped rod 203a-5 is fixed to the inner ring of the ring box 201, and the other end of the L-shaped rod 203a-5 rotates around the outer ring of the nozzle 203a-3.

[0046] The angle of the nozzle 203a-3 can be adjusted by the telescopic tube 203a-2, while ensuring the overall sealing of the nozzle component 203a. The slider 203a-6 can limit the movement of the control component 203b. The first transmission plate 203a-4 can be used to adjust the angle of the nozzle 203a-3 by controlling the control component 203b. A torsion spring is provided at the rotatable connection between the L-shaped rod 203a-5 and the nozzle 203a-3.

[0047] Specifically, the control component 203b includes a sleeve 203b-1 that slides on the inner ring of the fixed tube 203a-1, a sliding groove 203b-2 symmetrically opened on the outer ring of the sleeve 203b-1, a baffle 203b-3 fixed to one end of the sleeve 203b-1 away from the fixed tube 203a-1, and a spring 203b-4 disposed on the outer ring of the sleeve 203b-1. One end of the sleeve 203b-1 is fixedly connected to a second transmission plate 203b-5. One end of the second transmission plate 203b-5 is provided with an arc-shaped groove 203b-6. The second transmission plate 203b-5 corresponds to the first transmission plate 203a-4. One end of the first transmission plate 203a-4 is hinged to the arc-shaped groove 203b-6. The sliding groove 203b-2 is slidably engaged with the slide bar 203a-6.

[0048] Furthermore, the adjustment assembly 204 includes a circular ring 204a that rotates inside the ring box 201 via bearings, a plurality of push plates 204b that are uniformly fixed to the outer ring of the circular ring 204a, and a first through groove 204c, a second through groove 204d, and a third through groove 204e formed on the circular ring 204a. The first through groove 204c, the second through groove 204d, and the third through groove 204e have the same length, and the first through groove 204c, the second through groove 204d, and the third through groove 204e have different widths.

[0049] Furthermore, a pad 204f is fixedly connected to the inner ring of the ring 204a, and a mating groove 204g is provided on the inner ring of the ring 204a. Both the pad 204f and the mating groove 204g are slidably engaged with the baffle 203b-3.

[0050] By sliding the baffle 203b-3 with the adjusting component 204, the sleeve 203b-1 can be pushed, controlling the extension and retraction of the sleeve 203b-1. This allows for the adjustment of the nozzle 203a-3 angle. Furthermore, by contacting the baffle 203b-3 with the first through groove 204c, the second through groove 204d, and the third through groove 204e, the water pressure sprayed from the nozzle 203a-3 can be changed. This change in water pressure protects the polytetrafluoroethylene hollow fiber membrane filaments, preventing damage caused when the PTFE hollow fiber membrane filaments move slowly and are rinsed with the same water pressure.

[0051] Furthermore, the number of pads 204f and mating grooves 204g can be increased or decreased depending on the usage, and the correspondence between pads 204f, mating grooves 204g and the first through groove 204c, the second through groove 204d, and the third through groove 204e can also be adjusted according to the usage.

[0052] Through append Figure 9 ~Appendix Figure 11 It can be clearly seen that after the first channel 204c, the second channel 204d, and the third channel 204e come into contact with the baffle 203b-3, the angle of the nozzle 203a-3 changes. When the baffle 203b-3 corresponds to the mating groove 204g, the torsion spring set at the rotating connection between the L-shaped rod 203a-5 and the nozzle 203a-3 drives the nozzle 203a-3 to rotate. The spring 203b-4 drives the baffle 203b-3 to approach the mating groove 204g. By adjusting the combination of the component 204 and the water spray component 203, the water pressure at the nozzle 203a-3 can be changed. At the same time, the rotation of the nozzle 203a-3 can achieve large-area cleaning of the polytetrafluoroethylene hollow fiber membrane filaments. The rotation of the nozzle 203a-3 can also achieve a certain cleaning effect on the cleaning roller 105d, cleaning the modified solution adhering to the cleaning roller 105d.

[0053] In use, the water supply pipe 202 is opened to supply water into the ring box 201. The flow of water drives the push plate 204b to rotate the ring 204a. The rotation of the ring 204a causes the inner ring of the ring 204a, the pad 204f, and the mating groove 204g to cooperate with the baffle 203b-3, thereby moving the sleeve 203b-1. The second transmission plate 203b-5 and the first transmission plate 203a-4 then rotate the nozzle 203a-3. The water pressure sprayed from the nozzle 203a-3 is changed by the first through groove 204c, the second through groove 204d, and the third through groove 204e, which can achieve a cleaning effect on the polytetrafluoroethylene hollow fiber membrane filaments. Furthermore, the protection function of the polytetrafluoroethylene hollow fiber membrane filaments can be achieved by changing the water pressure and angle.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
