Description

Technical Field

[0001] This invention relates to the field of fiber membrane product manufacturing technology, and in particular to a membrane bundle dispersion treatment device and method. Background Technology

[0002] Plasma separators primarily utilize the osmosis principle of semi-permeable membranes to draw a patient's blood from inside the body to outside. The blood cells and plasma containing pathogenic substances are then separated through hollow fibers, thereby treating autoimmune diseases, metabolic diseases, and endogenous or exogenous toxemia. The manufacturing process of a plasma separator involves inserting a fiber semi-permeable membrane into a shell, followed by sealing, glue injection, centrifugation, removal of the glue from both ends, and installation of end caps to produce the finished plasma separator.

[0003] Currently, in the gel injection process of plasma separators, there is an issue where the semi-permeable membranes in certain areas become excessively dense. During the gel injection process, due to the high molecular weight and viscosity of the specific polyurethane adhesive, the excessive aggregation of the semi-permeable membranes in the membrane bundle prevents the adhesive from fully penetrating into the membrane bundle, resulting in areas with insufficient adhesive. In the process of large-scale production of plasma separators, this leads to a large number of defective products, affecting the quality stability and production efficiency of plasma separator products.

[0035] Reference Figure 1 and Figure 2 This invention discloses a membrane bundle dispersion processing device, including a frame 500 and a membrane bundle fixing mechanism 100, an electrostatic generator, and a first driving mechanism 400, all disposed on the frame 500. The membrane bundle fixing mechanism 100 is used to fix the membrane bundle; the electrostatic generator includes an electrostatic bar 200; the output end of the first driving mechanism 400 is connected to the electrostatic bar 200, and the first driving mechanism 400 is used to drive the electrostatic bar 200 to sweep across the ends of the membrane bundle on the membrane bundle fixing mechanism 100. The electrostatic bar 200 can charge the membrane bundle, so that all the semipermeable membranes in the membrane bundle are charged with the same charge.

[0036] Based on the principle of mutual repulsion of like charges, an appropriate distance will be maintained between adjacent semipermeable membranes to achieve rapid and relatively uniform dispersion of the membrane bundles without affecting their physical properties. The well-dispersed and flat membrane bundles are beneficial to ensuring the quality of subsequent sealing and glue injection processes, thereby helping to improve the efficiency and quality of manufacturing plasma separators.

[0037] In some embodiments, a support frame 510 is provided in the middle of the frame 500. The electrostatic generator also includes an electrostatic generator body 300 placed on the support frame 510. The electrostatic generator body 300 is connected to the electrostatic rod 200 via a cable, and the electrostatic generator body 300 causes the electrostatic rod 200 to have the same charge. The frame 500 includes a desktop and four support legs. The support frame 510 is a horizontal plate connected to the middle of the four support legs. The membrane bundle fixing mechanism 100 and the first drive mechanism 400 are both located on the desktop. The electrostatic generator meets the requirements of DC voltage 22KV and current 13-15μA.

[0038] The membrane dispersion treatment device also includes a PLC control system (not shown in the figure), which is connected to the first drive mechanism 400 and controls the operation of the first drive mechanism 400.

[0039] See Figure 1 and Figure 3 In this embodiment, the electrostatic rod 200 is cylindrical, and a flat surface is provided on the outer circumference of the electrostatic rod 200. This flat surface is used to contact the ends of the membrane bundle, that is, the flat surface of the electrostatic rod 200 is used to contact one end of all the semi-permeable membranes in the membrane bundle. The electrostatic rod 200 is made of Teflon material.

[0040] In some embodiments, a sliding mechanism 700 is provided on the frame 500. The sliding mechanism 700 includes a second drive mechanism (not shown in the figure) and a sliding rail 710 and a slider 720 that cooperate with each other. The second drive mechanism and the sliding rail 710 are both located on the table of the frame 500. The output end of the second drive mechanism is connected to the slider 720. One end of the sliding rail 710 is close to the membrane bundle fixing mechanism 100. The first drive mechanism 400 is located on the slider 720. The second drive mechanism drives the slider 720 to move, which can drive the first drive mechanism 400 to move. The slider 720 and the first drive mechanism 400 carrying the electrostatic bar 200 move along the length direction of the sliding rail 710, which can make the first drive mechanism 400 and the electrostatic bar 200 move closer to or away from the membrane bundle fixing mechanism 100.

[0041] When the first driving mechanism 400 and the electrostatic rod 200 approach the membrane bundle fixing mechanism 100, that is, when the sliding mechanism 700 drives the first driving mechanism 400 to approach the membrane bundle fixing mechanism 100, the first driving mechanism 400 can drive the electrostatic rod 200 to sweep across the end of the membrane bundle on the membrane bundle fixing mechanism 100, thereby completing the charging of the membrane bundle. When the electrostatic rod 200 has finished charging the end of the membrane bundle or at the beginning, the first driving mechanism 400 and the electrostatic rod 200 are driven away from the membrane bundle fixing mechanism 100, that is, when the sliding mechanism 700 drives the first driving mechanism 400 away from the membrane bundle fixing mechanism 100, space can be left around the membrane bundle fixing mechanism 100 so that the charged membrane bundle can be removed from the membrane bundle fixing mechanism 100 and the membrane bundle to be charged can be fixed on the membrane bundle fixing mechanism 100.

[0042] The second drive mechanism is connected to the PLC control system, which controls the operation of the second drive mechanism. The second drive mechanism can be a cylinder or an electric actuator.

[0043] See Figure 1 and Figure 2 In some embodiments, the membrane bundle fixing mechanism 100 includes a bracket 110 and a carrier 120. The carrier 120 is provided with a limiting channel 121 for the membrane bundle to pass through. The membrane bundle is passed through the limiting channel 121 so that the carrier 120 can limit and fix the membrane bundle.

[0044] The support 110 is mounted on the frame 500, and the carrier 120 is detachably mounted on the support 110, thereby limiting and fixing the carrier 120 and the membrane bundle on the frame 500. Because the carrier 120 is detachably mounted on the support 110, the carrier 120 and the membrane bundle can be set up conveniently and quickly. The carrier 120 can be placed on the support 110 first, and then the membrane bundle can be inserted into the limiting channel 121; alternatively, the carrier 120 can be removed from the support 110, the membrane bundle can be inserted into the limiting channel 121, and then the carrier 120 can be placed on the support 110. Furthermore, the carrier 120 can carry the membrane bundle to the next process, achieving versatility of the carrier 120 across various processes.

[0045] See Figure 3 It is understood that the side walls at both ends of the carrier 120 are provided with connecting pipes 122, and each connecting pipe 122 is provided with a connecting port. Both connecting ports are connected to the limiting channel 121, and the membrane bundle in the limiting channel 121 can be sealed and injected with glue through the connecting ports. The carrier 120 is made of polypropylene material.

[0046] In some embodiments, the bracket 110 includes two support plates both mounted on the frame 500. Each support plate has a first limiting groove 111 at its upper end. The two ends of the carrier 120 are respectively positioned within the two first limiting grooves 111, which serve to limit the movement of the carrier 120. When the carrier 120 straddles the two support plates, its two ends are positioned on opposite sides of the two support plates.

[0047] In some embodiments, the carrier 120 is cylindrical, and the limiting channel 121 is the central hole of the carrier 120. The inlet and outlet of the limiting channel 121 are respectively located on the two end faces of the carrier 120. The first limiting groove 111 on the support plate is U-shaped. The opening of the first limiting groove 111 is opened on the upper end face of the support plate, and the two ends of the first limiting groove 111 are respectively opened on the two sides of the support plate. The two support plates are parallel to each other, and the two first limiting grooves 111 have the same structure and are coaxial. The two first limiting grooves 111 can prevent the carrier 120 from rolling.

[0048] It is conceivable that the two connecting pipes 122 of the vehicle 120 can respectively abut against the opposite sides of the two support plates, which can prevent the vehicle 120 from moving along its axis or along the line connecting the two support plates.

[0049] In some embodiments, the output end of the first driving mechanism 400 faces the membrane bundle fixing mechanism 100, and the output end of the first driving mechanism 400 is connected to a fixing clip 600. The first driving mechanism 400 is detachably connected to the electrostatic bar 200 through the fixing clip 600. The fixing clip 600 facilitates the installation and removal of the electrostatic bar 200.

[0050] See Figure 2 In some embodiments, the fixing clamp 600 is provided with a second limiting groove 610, and the electrostatic rod 200 is placed in the second limiting groove 610. Part of the structure of the electrostatic rod 200 protrudes from the surface of the fixing clamp 600 so that part of the structure of the electrostatic rod 200 can sweep across the end of the membrane bundle. The first driving mechanism 400 drives the fixing clamp 600 to move, and the fixing clamp 600 carries the electrostatic rod 200 to move. Since the membrane bundle fixing mechanism 100 fixes the position of the membrane bundle, the moving electrostatic rod 200 can sweep across the end of the membrane bundle.

[0051] In some embodiments, the first driving mechanism 400 is a linear driving mechanism, such as a cylinder or an electric actuator. The linear driving mechanism drives the fixing clamp 600 to move in a straight line, so that the movement trajectory of the electrostatic bar 200 is a straight line. The movement trajectory of the electrostatic bar 200 is perpendicular to the axial direction of the membrane bundle fixed by the membrane bundle fixing mechanism 100 and intersects with the end of the membrane bundle. Alternatively, the movement trajectory of the electrostatic bar 200 is coaxial with the membrane bundle fixed by the membrane bundle fixing mechanism 100.

[0052] In this embodiment, since the height of the membrane bundle fixing mechanism 100 is greater than the height of the first driving mechanism 400, the first driving mechanism 400 is vertically arranged, and the output end of the first driving mechanism 400 faces upward. The second limiting groove 610 is U-shaped. The fixing clamp 600 includes a bottom plate at one end and support plates respectively disposed on both ends of the bottom plate. The second limiting groove 610 is opened on the upper end surface of the support plate, and the two ends of the second limiting groove 610 are respectively opened on the two sides of the support plate. The two second limiting grooves 610 are coaxial, and the two ends of the electrostatic rod 200 are respectively placed in the two second limiting grooves 610.

[0053] It is understood that in other embodiments, when the height of the first driving mechanism 400 is equal to or almost flush with the height of the membrane bundle fixing mechanism 100, the first driving mechanism 400 is horizontally positioned and the output end of the first driving mechanism 400 faces the membrane bundle fixing mechanism 100.

[0054] Of course, the first drive mechanism 400 can be configured in any way that ensures the trajectory of the electrostatic bar 200 driven by the first drive mechanism 400 overlaps with the end of the membrane bundle fixed by the membrane bundle fixing mechanism 100. The first drive mechanism 400 can also be other types of mechanisms, such as swing arm, crank connecting rod, multi-link mechanism, etc.

[0055] In some embodiments, the membrane bundle dispersion processing apparatus includes a frame 500, a membrane bundle fixing mechanism 100, an electrostatic generator, a first drive mechanism 400, and a PLC control system. A support frame 510 is provided in the middle of the frame 500. The electrostatic generator includes an electrostatic bar 200 and an electrostatic generator body 300 disposed on the support frame 510. The electrostatic generator body 300 is connected to the electrostatic bar 200 via a cable. The tabletop of the rack 500 has two support plates, a slide rail 710, and a second drive mechanism. The slide rail 710 and the two support plates are coaxially arranged. Each support plate has a U-shaped first limiting groove 111, on which a carrier 120 is supported. The carrier 120 is cylindrical and has a limiting channel 121 for the membrane bundle to pass through. The slide rail 710 has a slider 720. The first drive mechanism 400 is a vertically arranged linear drive mechanism, such as a cylinder. The output end of the second drive mechanism is connected to the slider 720 or the linear drive mechanism. The linear drive mechanism has a fixing clamp 600, and the electrostatic rod 200 is connected to the output end of the linear drive mechanism through the fixing clamp 600. The PLC control system is connected to the first drive mechanism 400 and the second drive mechanism.

[0056] This invention discloses a membrane bundle dispersion treatment method, which includes the following process steps: charging the membrane bundle so that all semipermeable membranes in the membrane bundle have the same charge, and using the principle of mutual repulsion of like charges to complete the membrane bundle dispersion treatment.

[0057] It is understood that the membrane dispersion treatment method can be implemented based on the above-mentioned membrane dispersion treatment device.

[0058] Furthermore, in the initial state, the sliding mechanism 700 drives the first driving mechanism 400 and the electrostatic rod 200 away from the membrane bundle fixing mechanism 100, and both the first driving mechanism 400 and the electrostatic rod 200 are lower than the membrane bundle fixing mechanism 100. Then, the membrane bundle is placed on the membrane bundle fixing mechanism 100. The PLC control system controls the first driving mechanism 400 and the sliding mechanism 700 to work. The sliding mechanism 700 drives the first driving mechanism 400 and the electrostatic rod 200 closer to the membrane bundle fixing mechanism 100, so that the first driving mechanism 400 and the electrostatic rod 200 are below one end of the membrane bundle on the membrane bundle fixing mechanism 100. Then, the first driving mechanism 400 drives the electrostatic rod 200 to sweep across one end of the membrane bundle, thereby completing the charging of the membrane bundle and the dispersion of the membrane bundle. When the membrane bundle is fully charged, the first driving mechanism 400 drives the electrostatic rod 200 to reset, and the sliding mechanism 700 drives the first driving mechanism 400 and the electrostatic rod 200 to reset. Then, the dispersed membrane bundle can be removed.

[0059] The membrane bundle dispersion treatment method has all the beneficial effects of the membrane bundle dispersion treatment device described in the above embodiments. By charging the membrane bundle with the same charge, the membrane bundle can be dispersed quickly and the dispersion effect is very good.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
