Description

Technical Field

[0001] The present invention belongs to the technical field of hollow fiber membrane manufacturing, and in particular relates to a hollow fiber membrane yarn bundle collecting device and a production line. Background Art

[0002] Hollow fiber membranes are self-supporting, fiber-like membranes. They are a type of asymmetric membrane, with a dense layer located either on the outer surface of the fiber (as in reverse osmosis membranes) or on the inner surface (as in microfiltration and ultrafiltration membranes). Hollow fiber membrane production requires the combination of an external fiber liquid material and an internal core liquid material, followed by extrusion molding. The core liquid is then removed to create a hollow structure, followed by cleaning, drying, and curling.

[0003] The inventors discovered during actual use that these prior arts have at least the following technical problems: The existing bundle collection device of the hollow fiber membrane production line cannot rewind after replacing the collection wheel, resulting in waste of the bundle. At the same time, the tensioning torque is difficult to flexibly control according to the number of wires in the bundle, resulting in affected yield of the bundle. At the same time, due to the volume of the bundle collection device itself, the angle between the two strands of wire on both sides of the collection machine is large, and the bundle is aggravated by the large angle, which affects the yield of the bundle. It is also difficult to use a multi-line bundle collection device.

[0004] Existing hollow fiber membrane production lines are bulky and have high ceilings. This is because they utilize a single cantilevered loading system. When loading the membrane filaments, the cantilever must be lifted off the equipment before installation can begin. This is inconvenient and requires high production line heights, requiring either high ceilings or a sunken cleaning area, which is unfavorable for existing plant structures. Furthermore, during production, the multiple membrane filaments are guided by fixed needles, which are easily damaged, resulting in high costs and inconvenient maintenance. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings, the inventors of the present invention have continuously reformed and innovated through long-term exploration and attempts, multiple experiments and efforts, and proposed a hollow fiber membrane production line, which uses a combing needle with a ring at the tail, and the needles are separated by gaskets, and there are locking nuts on both sides for pre-tightening. When adjusting the left and right positions of the combing needles, it is sufficient to adjust the positions of the left and right locking nuts, which is convenient to adjust. At the same time, when the film breaks during the operation of the equipment, the active roller will be wrapped with membrane wire. The traditional welded combing needles will be affected by the fixed position and will squeeze the combing needles or bend the active roller. However, this structure can be squeezed by the roller membrane wire force. When the extrusion force exceeds the locking friction force, the combing needles will be squeezed open. When recovering later, it is only necessary to adjust the position and pre-tighten the locking nuts. It is easy to maintain and not easy to damage.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: to provide a hollow fiber membrane yarn bundle collection device, which includes a buffer and a collector, the buffer includes a column, a filament separation comb, a first static eliminator, an active roller, and a passive roller, passive rollers are arranged on the sliders that slide up and down on both sides of the upper part of the column, active rollers are arranged on both sides of the lower part of the column, and an auxiliary column is arranged, and a first static eliminator is arranged at the upper end of the auxiliary column for static elimination before the filament bundle enters the filament separation comb, and a filament separation comb is arranged in front of the active roller at the lower end. After passing through the filament separation comb, the filament bundle enters the collector through the active roller and the passive roller, the collector includes a power main unit and a collecting wheel, and collecting wheel interfaces are arranged on both sides of the power main unit, and collecting wheels are vertically installed on the collecting wheel interfaces corresponding to the filament bundles on both sides of the buffer, and the collecting wheel is arranged in a regular hexagonal shape.

[0010] According to the hollow fiber membrane yarn collecting bundle device described in the present invention, its further preferred technical solution is: the power main unit includes an outer shell and a power mechanism, the power mechanism is located inside the outer shell, the power mechanism includes a motor, a magnetic powder clutch, a reversing gear set, a rotating clutch assembly, and a collecting wheel interface. The driving motor transmits power to the magnetic powder clutch, and then changes the power direction to the side through the reversing gear set, and then transmits the power to the rotating clutch assembly through a belt. The rotating clutch assembly controls the clamping and loosening of the collecting wheel interface through the clamping and separation cylinder of the collecting wheel shaft.

[0011] A hollow fiber membrane production line comprises a batching device, a spinning device, a cleaning device, a drying device, and a fiber bundle collection device, which are arranged in sequence. The batching device includes a core liquid preparation device and a fiber liquid preparation device. The spinning device includes a pump station, a hot water station, and a spinning main unit. The cleaning device includes a cleaning tank and a cantilevered wire pressing device within the tank. The drying device is provided with a fiber bundle collection device for guiding the membrane fibers. The fiber bundle collection device comprises a driving drum, combing needles, a gasket, and a locking nut. The combing needles are an integrated structure with a ring at the rear end. The combing needles are mounted on a mounting rod below the driving drum using the tail ring. The combing needles are separated by gaskets and have locking nuts on both sides for pre-tightening to press the combing needles and gaskets together.

[0012] According to the hollow fiber membrane production line described in the present invention, a further preferred technical solution is that the spinning equipment adopts a straight head layout.

[0013] According to the hollow fiber membrane production line described in the present invention, its further preferred technical solution is: the cleaning device is equipped with 5-section cleaning tanks, new water enters from the fifth cleaning section, overflows to the fourth section, the third section, the second section and finally overflows to the first cleaning section, each cleaning section corresponds to a concentration, the membrane filament enters from the first cleaning section, passes through the second cleaning section to the fifth cleaning section in turn, and the membrane filament is removed from the lowest concentration tank.

[0014] According to the hollow fiber membrane production line described in the present invention, its further preferred technical solution is: a cantilever wire pressing device is arranged in the cleaning tank of the cleaning equipment, and the cantilever wire pressing device includes a guide rail and a cantilever. The middle part of the cantilever is slid up and down and is installed on the vertically arranged guide rail. Wire pressing wheels are arranged at the lower ends of the left and right sides of the cantilever, and the membrane wire passes through the wire pressing wheels from both sides of the cantilever and is pressed down and tensioned.

[0015] According to the hollow fiber membrane production line described in the present invention, its further preferred technical solution is: a powered driving wheel is set at the upper end of the guide rail, a powered passive wheel is set at the lower end, a slider is installed on the guide rail, a cantilever is installed on the slider, the driving wheel and the passive wheel are connected by a chain, and the slider is connected to the chain and is driven up and down by the driving wheel.

[0016] According to the hollow fiber membrane production line described in the present invention, a further preferred technical solution is that triangular hollow reinforcement ribs are provided on the upper part of the cantilever to improve the supporting force.

[0017] According to the hollow fiber membrane production line described in the present invention, its further preferred technical solution is: the hot water station is used to heat the pump station and the spinning main machine, and the spinning main machine heating includes heating the main machine core liquid pipeline, heating the silk liquid pipeline, and heating the spray plate frame.

[0018] According to the hollow fiber membrane production line described in the present invention, its further preferred technical solution is: the drying equipment adopts multi-stage drying, and the temperature gradually increases from the entry to the delivery of the membrane, and the temperatures are 90°C, 105°C, 110°C, and 120°C respectively, and the front low-temperature drying chamber recovers the heat of the rear high-temperature drying chamber to achieve heating.

[0019] Compared with the prior art, the technical solution of the present invention has the following advantages / benefits: The buffer in the tow collection unit temporarily stores tow that the tow collector cannot reel in by moving the upper passive roller group up and down. The lower active roller transports the tow back to the collector. This mechanism features a simple structure and stable operation. This buffer mechanism significantly reduces the waste of tow that cannot be reeled in during the reel change.

[0020] 2. The film winder utilizes an adjustable torque mechanism to generate a constant torque on the take-up wheel. This adjustable torque mechanism allows the take-up wheel to adapt to the number of yarns being wound (the required pulling force must be adjusted accordingly, neither too large nor too small). The static eliminator and guide mechanism are auxiliary mechanisms that ensure more stable and regular collection of the yarns. The aspirator is used to temporarily pull the yarns when the take-up wheel is replaced.

[0021] 3. The rotational torque of the receiving wheel can be precisely adjusted by adjusting the current of the magnetic powder clutch, which can perfectly match the tow winding of different tow numbers of the spinning machine (the tow winding force cannot be too large or too small, it must be just right); the reversing gear set changes the power direction to both sides, so that the main body of the receiving machine can be as narrow as possible, so that the angle between the two tows on both sides of the receiving machine can be as small as possible, thereby reducing the wear of the tow caused by the large angle, thereby improving the yield of the tow; the rotary clutch assembly can effectively balance the functions of the receiving wheel to rotate and to take and put the receiving wheel. Its function is mainly realized by the separation cylinder, which clamps the shaft of the receiving wheel when retracting and releases the shaft of the receiving wheel when extending. During this period, the rotation power can be stopped and started by cutting off and connecting the input current of the magnetic powder clutch. This ensures that the drive motor runs continuously without frequent starting and stopping.

[0022] 4. The tow-splitting device uses combing needles with a ring at the tail. The needles are separated by gaskets and pre-tightened with locking nuts on both sides. When adjusting the left and right positions of the combing needles, just adjust the position of the left and right locking nuts, which is easy to adjust. At the same time, when the film breaks during operation of the equipment, the film yarn will be wrapped around the active roller. Traditional welded combing needles will be affected by the fixed position and may damage the combing needles or bend the active roller. However, this structure can be squeezed by the film yarn force of the roller. When the squeezing force exceeds the locking friction force, the combing needles will be squeezed apart. Later, when the machine is restored, it only needs to remove the broken yarn and adjust the position to pre-tighten the locking nuts. It is easy to maintain and not easy to damage.

[0023] 5. The entire cantilevered wire pressing device is installed in the water tank, which reduces the overall height of the cleaning equipment. The equipment does not require a pit to be sunk in the factory building, thus reducing the requirements for the factory building and the factory area. The cleaning equipment is installed in a Class 100,000 clean room. Due to the high overall requirements of the equipment, the ceiling height of the cleaning equipment area can be reserved at 3.5 meters. Compared with the ceiling height of traditional equipment cleaning areas, the height can be reduced by one-third. This can reduce the energy consumption of clean air conditioning during equipment operation and the power consumption of clean area air conditioning, thereby reducing operating costs.

[0037] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the detailed description of the embodiments of the present invention provided below is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0038] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0039] Example 1: like Figures 8-11 As shown, a hollow fiber membrane yarn collection bundle device includes a buffer 51 and a collection device 52. The buffer 51 includes a column 511, a filament comb 512, a first static eliminator 513, an active roller 514, and a passive roller 515. The passive roller 515 is set on the sliders that slide up and down on both sides of the upper part of the column 511, and the active roller 514 is set on both sides of the lower part of the column 511. A secondary column 517 is set. The secondary column 517 is located in front of the column 511. The first static eliminator 513 is set at the upper end of the secondary column 517 for In order to eliminate static electricity before the tow enters the separating comb 512, a separating comb 512 is set at the bottom of the auxiliary column 517. The separating comb 512 is before the active roller. After the tow passes through the separating comb 512, it enters the collector 52 through the active roller and the passive roller. The collector 52 includes a power main unit 521 and a collecting wheel 522. The power main unit 521 is provided with a collecting wheel interface 5265 on both sides. The collecting wheels 522 are vertically installed on the collecting wheel interface 5265 to correspond to the tow on both sides of the buffer 51. The collecting wheels 522 are set in a regular hexagonal shape. As can be seen from the figure, active rollers and passive rollers are set on both sides of a buffer 51, and a collecting wheel 522 is set on each side of a collector 52 to achieve double-line collection. At the same time, two buffers 51 and collectors 52 are arranged at the rear end of the equipment to achieve four-line collection. The collecting wheel 522 is set to a regular hexagonal shape, which can conveniently coat the straight section of the wire bundle of the collecting wheel 522 into a bundle. At the same time, the regular hexagon can also avoid the control of the tensioning force of the collecting wheel 522.

[0040] The column 511 of the buffer 51 is located on the slide rail 518. The distance between the column 511 and the wire collector 52 is adjusted by sliding the column 511. Therefore, the sliding direction of the slide rail can be set according to the sliding requirements.

[0041] There are three active rollers and three passive rollers on each side, which are, according to the direction of the tow entering, the first active roller 5141, the second active roller 5142, and the third active roller 5143; the first passive roller 5151, the second passive roller 5152, and the third passive roller 5153. A second static eliminator 519 is provided near the third passive roller 5153 to eliminate static electricity in the tow output buffer 51. It can be seen that the first passive roller 5151 and the second passive roller 5152 are mounted on the same slider 516 to form a moving passive roller group. The slider is actively driven to slide up and down on the column 511, thereby changing the distance between the first passive roller 5151, the second passive roller 5152 and the active roller 514, thereby achieving the tow caching capacity. Of course, the provision of two passive rollers is only a form. If necessary, more movable rollers can be provided, or the moving distance can be increased, both of which can achieve a longer tow caching capacity.

[0042] A guide 523 and a yarn aspirator 524 are provided at the upper end of the yarn collector 52. The guide 523 is located in front of the yarn collecting wheel 522 and adopts a comb structure with adjustable direction to guide the direction of the yarn bundle. An electrostatic elimination device 5231 is provided near the guide 523. The yarn aspirator 524 is a bracket located behind the yarn collecting wheel 522. The yarn aspirator 524 is used for temporarily pulling the yarn bundle when the yarn collecting wheel 522 is replaced. The guide 523 is mainly used to adjust the direction of the filament bundle wound on the collecting wheel 522, and at the same time eliminate static electricity through the static elimination device 5231. The static elimination device 5231 is actually composed of two static eliminators. Of course, other elimination devices can also be used. The direction adjustment of the guide 523 can be achieved by various joint structures or slide structures, which will not be repeated here. The wire suction device 524 adopts a hollow conduit, which is narrowed near the end and uses the working principle of the Venturi ejector to create negative pressure, and absorb the excess filament bundle from the port to achieve continuous tension. Of course, other methods can also be used to tension the filament bundle, such as using a mechanical structure to suspend the filament bundle using a bracket, or other methods can be used for adsorption, such as creating negative pressure for adsorption.

[0043] The power host 521 includes a shell 525 and a power mechanism 526. The power mechanism 526 is located inside the shell 525. The power mechanism includes a motor 5261, a magnetic powder clutch 5262, a reversing gear set 5263, a rotary clutch assembly 5264, and a wire collecting wheel interface 5265. The driving motor 5261 transmits power to the magnetic powder clutch 5262, and then changes the power direction to the side through the reversing gear set 5263. The reversing gear set 5263 also realizes the transmission and synchronization of power on both sides at the same time. The time for changing the wire bundle will be fixed, and the length of the wire bundle can be accurately controlled. The power is then transmitted to the rotary clutch assembly 5264 through the belt 5266. The rotary clutch assembly 5264 controls the clamping and release of the wire collecting wheel interface 5265 through the clamping and separation cylinder of the wire collecting wheel 522 shaft.

[0044] Example 2: like Figure 1 As shown, a hollow fiber membrane production line. It includes a batching device 1, a spinning device 2, a cleaning device 3, a drying device 4, and a fiber bundle collecting device 5 arranged in sequence. The batching device 1 includes a core liquid preparation device 11 and a fiber liquid preparation device 12. The spinning device 2 includes a pump station 21, a hot water station 22, and a spinning main machine 23. The cleaning device 3 includes a cleaning tank 31 and a cantilevered wire pressing device 32 in the tank. The drying device 4 is provided with a fiber bundle device 41 for guiding the membrane fibers 6. Figure 2-Figure 5As shown, the filament bundle device 41 includes an active roller 411, a combing needle 412, a gasket 413, and a locking nut 414. The combing needle is an integrated structure with a ring at the rear end. The combing needle is mounted on the mounting rod 416 below the active roller 411 using the tail ring. The combing needles are separated by gaskets 413, and locking nuts are provided on both sides to pre-tighten the combing needles and the gaskets. At this time, the membrane filament 6 is tensioned and conveyed around the passive roller 415 and the active roller 411, and the combing needle 412 is used to guide and separate the membrane filaments 6. It can be seen at this time that the filament bundle device 41 is also installed in the middle, and the membrane filament 6 is conveyed from both sides, which can facilitate the threading of the membrane filament 6 and maintenance and troubleshooting. When adjusting the left and right positions of the combing needles, it is sufficient to adjust the positions of the left and right locking nuts, which is easy to adjust. At the same time, the installation structure of the integrated combing needle and the gasket is such that when the film breaks during the operation of the equipment, the film wire 6 will be wrapped around the active roller 411. The traditional welded combing needle will be affected by the fixed position and will squeeze the combing needle or bend the active roller 411. However, this structure can be squeezed by the force of the roller film wire 6. When the squeezing force exceeds the locking friction force, the combing needle will be squeezed open. When restoring later, it is only necessary to adjust the position and pre-tighten the locking nut. It is easy to maintain and not easy to damage. At the same time, the length and number of the combing needles can be flexibly adjusted.

[0045] The spinning apparatus 2 utilizes a straight die layout (i.e., a straight die layout for the main spinning unit). The extrusion sections of the spinning apparatus 2 are arranged parallel to each other. After extrusion, the spacing between the membrane filaments 6 is gradually reduced for cleaning. This ensures that, compared to a fan-shaped die, all material pipelines from the pump outlet to the nozzle plate are of equal length. This minimizes differences in pipeline resistance between the spinning units, thereby ensuring the stability of each spinning unit. This plays a crucial role in reducing the breakage rate of the entire equipment and ensuring the consistency of the finished product.

[0046] The cleaning device is equipped with a 5-section cleaning tank 31. New water enters from the fifth cleaning section, overflows to the fourth section, the third section, the second section, and finally overflows to the first cleaning section. Each cleaning section corresponds to a concentration. The membrane filament 6 enters from the first cleaning section, passes through the second cleaning section to the fifth cleaning section in turn, and the membrane filament 6 is removed from the lowest concentration tank. Of course, the specific number of sections of the cleaning tank 31 can be set according to demand, and the number of sections of the cleaning tank 31 can be increased or decreased if necessary.

[0047] like Figure 6-Figure 7As shown, a cantilever wire pressing device 32 is provided in the cleaning tank 31 of the cleaning device 3. The cantilever wire pressing device 32 includes a guide rail 321 and a cantilever. The middle part of the cantilever is slidably mounted on the vertically arranged guide rail 321. A wire pressing wheel 322 is provided at the lower end of the left and right sides of the cantilever. The film wire 6 passes through the wire pressing wheel from both sides of the cantilever and is pressed down and tensioned. The wire pressing wheel is equipped with a combing needle structure 327. A power driving wheel 323 is provided at the upper end of the guide rail 321, and a power driven wheel 324 is provided at the lower end. A slider 326 is installed on the guide rail 321, and a cantilever is installed on the slider 326. The driving wheel 323 and the driven wheel 324 are connected by a chain 325. The slider 326 is connected to the chain 325 and is driven by the driving wheel 323 to move up and down. Of course, this is a way of up and down displacement. Other ways of moving the slider 326 can also be adopted, such as a rack structure or a screw structure. The cantilever is equipped with triangular hollow reinforcement ribs on the upper portion to enhance support. These ribs, however, only serve to strengthen the connection and support, and their specific structure is not limited. The driving wheel 323 and the driven wheel 324 are driven by a chain 325. Chain 325 drives the slider 326 to slide along the guide rail 321, achieving the desired descent and wire pressing. The device is installed in a water tank, requiring only a power system above the water tank. The slider 326 is equipped with guide rollers, a driven wire pressing drum, and combing pins. The guide rollers ensure smooth descent and positioning, preventing the slider 326 from swinging. The driven wire pressing drums are mounted on either side of the slider 326 to pull the film yarn 6. This two-sided arrangement reduces operator complexity. When re-pulling the tow, operating from both sides reduces the operating span. There is no need to lift the entire wire pressing device out of the cleaning tank to pull the film yarn; simply raising the cantilever is sufficient. The driven wheel 324 has combing pins that ensure the film yarn 6 is positioned within the pre-set combing pins during the downward pressing process, preventing the film yarn 6 from becoming dislocated and becoming caught in the tow. The entire cantilever wire pressing device 32 is installed in the water tank, which can reduce the overall height of the cleaning equipment 3; the equipment does not need to be sunk in the factory building, and has low requirements for the factory building and adaptability to low requirements for the factory area. The cleaning equipment 3 is installed in a 100,000-level clean room. Due to the high overall requirements for the equipment, the ceiling height of the cleaning equipment 3 area can be reserved at 3.5 meters, which can be reduced by one-third compared with the ceiling height of the cleaning area of ​​traditional equipment. It can reduce the energy consumption of the clean air conditioner during the operation of the equipment and the air conditioning power of the clean area, thereby reducing operating costs. It can be seen that the wire bundle device 41 and the cantilever wire pressing device 32 are both fixed in the middle, and the membrane wire 6 is transferred on both sides, so that the overall structure of the equipment can be optimized. The cantilever wire pressing device transports from both sides of the cantilever, corresponding to the buffer and wire collector working on both sides, thereby improving production efficiency.

[0048] The hot water station is used to heat the pump station and the spinning machine. The pump station is mainly used to increase the fluidity of the silk solution or core liquid. The filter device also needs to be heated to increase fluidity and remove bubbles. The heating of the spinning machine mainly increases the fluidity of the silk solution and core liquid, facilitating the extrusion of the silk bundle with the core liquid in the middle. The heating of the spinning machine includes heating the main machine core liquid pipeline, heating the silk solution pipeline, and heating the spray plate frame. Of course, the hot water station can also heat other places as needed, such as heating the top of the machine.

[0049] The drying equipment 4 adopts multi-stage drying. The temperature gradually increases from the entry of the membrane wire to the delivery, and the temperatures are 90°C, 105°C, 110°C, and 120°C respectively. The front low-temperature drying chamber recovers the heat of the rear high-temperature drying chamber to achieve heating. This drying method can achieve heat recovery and save energy, and at the same time improve the drying efficiency.
