Description

Technical Field

[0001] This invention belongs to the field of adhesive injection technology, and in particular relates to an adhesive injection device and adhesive injection process for the end of a hollow fiber membrane filter element. Background Technology

[0002] Hollow fiber membrane filter cartridges are filtration elements widely used in material separation, concentration, and purification. Their structure includes a shell, inlet / return end, and outlet end. The shell is typically made of corrosion-resistant transparent polysulfone material to protect the internal fibers and maintain structural integrity. To ensure the performance and lifespan of hollow fiber membrane filter cartridges, end treatment is particularly important, and adhesive injection is a key process.

[0003] Traditional glue-filling equipment involves adding adhesive A and adhesive B to a plastic measuring cylinder in a specific ratio, then manually stirring with a glass rod until homogeneous. The glue is then poured into the hollow fiber membrane end cap. This method requires manual stirring and the membrane cap is prone to loosening during glue filling, significantly reducing efficiency. To address these issues, we provide a hollow fiber membrane filter element end-filling device and process to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a hollow fiber membrane filter element end glue injection device. Through the specific structural design of the L-shaped support plate, clamping assembly, glue injection assembly and power drive assembly, the device solves the problems of easy loosening of the membrane shell and low glue injection efficiency during the existing glue injection process.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a hollow fiber membrane filter element end-filling device and process, comprising an L-shaped support plate, a clamping assembly, a filling assembly, and a power drive assembly. The L-shaped support plate is mounted on an external frame, and a filling template is placed on top of the L-shaped support plate. The clamping assembly is mounted on top of the L-shaped support plate and includes two clamping plates symmetrically arranged above the L-shaped support plate to fix the position of the filling template. The filling assembly is mounted above the filling template and includes a filling container. A conical filling part is fixedly arranged at the bottom of the filling container, and the filling container and the conical filling part are internally connected. The power drive assembly is mounted on one side of the filling assembly and includes two moving plates symmetrically arranged on both sides of the filling container.

[0006] The present invention is further configured such that a positioning plate is fixedly provided on one side of the L-shaped support plate, the moving plate and the positioning plate are slidably engaged, a fixing plate is fixedly provided on the top of the positioning plate, a limiting plate is fixedly provided on the top of the L-shaped support plate, and the limiting plate and the clamping plate are slidably engaged.

[0007] The present invention is further configured such that the top of the glue injection template is provided with a glue inlet, one side of the clamping plate is provided with a positioning groove corresponding to the clamping plate, and a limiting groove is provided on the side of the clamping plate near the positioning groove, and two first connecting rods are fixedly provided inside the limiting groove.

[0008] The present invention is further configured such that a linkage rod is rotatably provided on the periphery of the first connecting rod, and the clamping assembly further includes a movable frame, the top of which is fixedly provided with a second connecting rod corresponding to the linkage rod, and the second connecting rod and the corresponding linkage rod are rotatably engaged.

[0009] The present invention is further configured such that the movable frame and the L-shaped support plate are slidably engaged, and a cylinder is installed on the inner side of the L-shaped support plate, the output end of the cylinder extending through to one side of the limiting plate and being fixedly connected to the movable frame.

[0010] The invention is further configured such that: a dispensing port is provided at the bottom of the conical dispensing component; a valve is installed inside the conical dispensing component; the dispensing port is located directly above the inlet; a plurality of filling ports are provided at the top of the dispensing container; a stirring rod is rotatably installed at the bottom of the dispensing container; a positioning frame is fixedly installed on the periphery of the dispensing container; sliding parts are fixedly installed on both sides of the positioning frame; an L-shaped support plate is fixedly installed on the top of the positioning frame; a first motor is installed on the top of the L-shaped support plate; and the output end of the first motor is fixedly connected to the stirring rod.

[0011] The invention is further configured such that a sliding opening is provided on one side of the movable plate, the sliding opening is slidably engaged with a corresponding sliding component, the two movable plates are fixedly connected by a connecting plate, a second motor is installed on one side of the fixed plate, a positioning threaded rod is rotatably provided on the other side of the fixed plate, the positioning threaded rod is threadedly engaged with the connecting plate, and the output end of the second motor is fixedly connected to the positioning threaded rod.

[0012] The present invention has the following beneficial effects: 1. This invention controls a first motor to drive a stirring rod to rotate, so that different waters are mixed evenly. Then, the valve is opened, and the mixed glue enters the glue injection template through the glue outlet. This process can complete the automatic glue injection at the end of the filter element. This process does not require manual stirring for glue injection, which greatly improves the glue injection efficiency at the end of the filter element.

Under the action of tension, the two clamping plates move towards each other, so that the glue injection template is clamped. During the glue injection process, the glue injection template will not shift, thereby improving the glue injection effect at the end of the filter element.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] For a specific implementation example, please refer to Implementation Example 1. Figure 1-7 This invention relates to a hollow fiber membrane filter element end-gluing device, comprising an L-shaped support plate 1, a clamping assembly 3, a glue-injection assembly 4, and a power drive assembly 5. The L-shaped support plate 1 is mounted on an external frame, and a glue-injection template 2 is placed on top of the L-shaped support plate 1. The clamping assembly 3 is mounted on top of the L-shaped support plate 1 and includes two clamping plates 301 symmetrically arranged above the L-shaped support plate 1 to fix the position of the glue-injection template 2. The glue-injection assembly 4 is mounted above the glue-injection template 2 and includes a glue-injection container 401. A conical glue-dispensing part 402 is fixedly arranged at the bottom of the glue-injection container 401, and the glue-injection container 401 and the conical glue-dispensing part 402 are internally connected. The power drive assembly 5 is mounted on one side of the glue-injection assembly 4 and includes two moving plates 501 symmetrically arranged on both sides of the glue-injection container 401.

[0026] Specifically, a positioning plate 101 is fixedly installed on one side of the L-shaped support plate 1, and the moving plate 501 slides with the positioning plate 101. A fixing plate 102 is fixedly installed on the top of the positioning plate 101, and a limiting plate 103 is fixedly installed on the top of the L-shaped support plate 1. The limiting plate 103 slides with the clamping plate 301, and an adhesive inlet 201 is opened on the top of the adhesive injection template 2.

[0027] The operation process of this embodiment is as follows: In the initial state, the glue injection component 4 is above the L-shaped support plate 1 (that is, the conical glue outlet 402 is above the glue inlet 201), and the two clamping plates 301 are at their farthest distance (see Appendix for details). Figure 1 As shown, the end of the filter element to be glued is placed inside the glue injection template 2. Then, the glue injection template 2 is placed on top of the L-shaped support plate 1, with the glue injection template 2 positioned between the two clamping plates 301. Subsequently, the internal structure of the clamping assembly 3 drives the two clamping plates 301 to move closer to each other until the glue injection template 2 is tightly clamped by the two clamping plates 301. Then, the power drive assembly 5 drives the glue injection assembly 4 to move downward, so that the conical glue outlet 402 is inside the glue inlet 201. Then, different glues are added to the glue injection container 401, and the internal structure of the glue injection assembly 4 is used to stir the different glues. Then, by opening the conical glue outlet 402, the glue injection template 2 can be glued. After the glue injection is completed, the conical glue outlet 402 is closed. Then, the power drive assembly 5 drives the glue injection assembly 4 to move upward back to the initial position, while controlling the two clamping plates 301 to move away from each other. Then, the end of the filter element that has been glued can be removed and the next end of the filter element to be glued can be replaced.

[0028] In the second specific embodiment, based on the first specific embodiment, a positioning groove 302 corresponding to the clamping plate 301 is provided on one side of the clamping plate 301, and a limiting groove 303 is provided on the side of the clamping plate 301 close to the positioning groove 302. Two first connecting rods are fixedly installed inside the limiting groove 303.

[0029] Specifically, a linkage rod 304 is rotatably provided on the circumferential side of the first connecting rod, and the clamping assembly 3 also includes a movable frame 305. A second connecting rod 306 corresponding to the linkage rod 304 is fixedly provided on the top of the movable frame 305, and the second connecting rod 306 and the corresponding linkage rod 304 are rotatably engaged.

[0030] Furthermore, the movable frame 305 and the L-shaped support plate 1 are slidably fitted together. A cylinder 307 is installed on the inner side of the L-shaped support plate 1. The output end of the cylinder 307 extends through to one side of the limit plate 103 and is fixedly connected to the movable frame 305.

[0031] The operation process of this embodiment is as follows: In the initial state, each linkage 304 and the movable frame 305 are in a perpendicular state (see Appendix for details). Figure 4 As shown, after the glue injection template 2 is placed, the drive cylinder 307 drives the moving frame 305 to move to the left. At this time, each linkage rod 304 moves. Under the action of tension, the two clamping plates 301 move towards each other until the glue injection template 2 is completely clamped. When it is necessary to release the clamp, the output end of the control cylinder 307 moves in the opposite direction, causing the moving frame 305 to move in the opposite direction. At this time, each linkage rod 304 moves in the opposite direction. Under the action of tension, the two clamping plates 301 move away from each other. At this time, the glue injection template 2 is released from clamping.

[0032] In the third specific embodiment, based on the first and second specific embodiments, a dispensing port is provided at the bottom of the conical dispensing part 402, a valve is installed inside the conical dispensing part 402, the dispensing port is located directly above the inlet port 201, and a number of filling ports 403 are provided at the top of the dispensing container 401.

[0033] Specifically, a stirring rod 404 is rotatably installed at the bottom of the glue injection container 401, a positioning frame 405 is fixedly installed on the periphery of the glue injection container 401, sliding parts 406 are fixedly installed on both sides of the positioning frame 405, an L-shaped support plate 407 is fixedly installed on the top of the positioning frame 405, a first motor 408 is installed on the top of the L-shaped support plate 407, and the output end of the first motor 408 is fixedly connected to the stirring rod 404.

[0034] Furthermore, a sliding opening 502 is provided on one side of the movable plate 501, and the sliding opening 502 is slidably engaged with the corresponding sliding member 406. The two movable plates 501 are fixedly connected by a connecting plate 503. A second motor 504 is installed on one side of the fixed plate 102, and a positioning threaded rod 505 is rotatably provided on the other side of the fixed plate 102. The positioning threaded rod 505 is threadedly engaged with the connecting plate 503, and the output end of the second motor 504 is fixedly connected to the positioning threaded rod 505.

[0035] The operation process of this embodiment is as follows: In the initial state, the valve is in the closed state, and the sliding member 406 is in the rightmost position of the sliding port 502 (see Appendix for details). Figure 2 and appendix Figure 6 As shown), the two moving plates 501 are positioned at the leftmost position of the positioning plate 101. Then, the second motor 504 drives the positioning threaded rod 505 to rotate. The connecting plate 503 moves to the right, causing the two moving plates 501 to move to the right. The sliding member 406 moves to the left along the sliding port 502 (i.e., the sliding member 406 moves downward). During this process, the positioning frame 405 moves downward, causing the glue injection container 401 to move downward until the conical glue outlet 402 is inside the glue inlet 201. Then, different glues are added to the glue injection container 401. The first motor 408 is controlled to drive the stirring rod 404 to rotate, so that the different glues are mixed evenly. Then, the valve is opened. At this time, the mixed glue enters the glue injection template 2 along the glue outlet. This process completes the glue injection at the end of the filter element.
