Description

Technical Field

[0001] This utility model relates to the field of hollow fiber membranes, and specifically to a hollow fiber membrane quick connector. Background Technology

[0002] Hollow fiber membranes are a type of filtration material with important applications in water treatment, chemistry, and medicine.

[0003] In some tests involving the performance of hollow fibers, it is necessary to encapsulate the membrane fibers. Current techniques involve submerging a large number of membrane fibers in epoxy resin or polyurethane adhesive, while simultaneously using gravity or centrifugal force to evenly distribute the adhesive between the fibers. This method not only consumes a large amount of membrane fibers and adhesive, but the large amount of adhesive used also means that drying takes more than 24 hours, thus significantly increasing the development cycle. Similarly, in some instruments that measure the pore size distribution of membrane fibers, it is also necessary to encapsulate individual membrane fibers. Current techniques involve using a specially designed sleeve with a diameter larger than the membrane fiber, placing it over the end of the fiber, and then injecting adhesive. However, this method suffers from poor adhesive uniformity during operation, the membrane fibers are prone to eccentric distribution, and the amount of adhesive injected cannot be controlled. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a hollow fiber membrane quick connector that enables rapid and precise encapsulation of membrane fibers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hollow fiber membrane quick connector is in the shape of a hollow tube, with a glue-filling tube extending through the top and reaching the middle of the quick connector; a gradually converging positioning tube is provided below the glue-filling tube, and the bottom of the positioning tube penetrates the bottom of the quick connector to form a positioning hole.

[0007] Furthermore, the positioning tube is a gradually converging cone shape.

[0008] Furthermore, the positioning tube is provided with several stepped holes from top to bottom.

[0009] Furthermore, the outer wall surface, facing the positioning tube, is provided with scale lines arranged along the axial direction.

[0010] This invention enables precise splicing, potting, and encapsulation of single membrane filaments, and the positioning tube can adapt to membrane filaments of different diameters for encapsulation. Attached Figure Description

[0014] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0015] Example 1

[0016] like Figures 1 to 2 As shown, the present invention provides a hollow fiber membrane quick connector, which is in the shape of a hollow tube. The top of the tube is provided with a glue-filling tube 1 that extends through the top and extends to the middle of the quick connector. Below the glue-filling tube 1 is a gradually converging positioning tube 2, and the bottom of the positioning tube 2 extends through the bottom of the quick connector to form a positioning hole 3.

[0017] This invention preferably uses inexpensive plastics such as PVC and PC to make a rigid plastic tube, which can be mass-produced using molds, thus serving as a low-cost disposable consumable. Preferably, the product height is approximately 30mm-50mm, and the outer diameter is 6mm-10mm. Preferably, the inner diameter of the glue-filling tube 1 is between 5mm-8mm. The positioning tube 2 can be appropriately cut to change the size of the positioning hole 3, accommodating different membrane filament diameters 100. The diameter of the positioning hole 3 is 100-200 micrometers larger than the diameter of the membrane filament 100.

[0018] like Figure 3 As shown, in use, the membrane fiber 100 is quickly inserted through the positioning hole 3, with the tip of the membrane fiber 100 extending 30-50mm. Then, quick-drying adhesive, such as 401 adhesive or UV-curing adhesive, is poured into the gap between the membrane fiber 100 and the dispensing tube 1 until it is full. The connector designed in this invention allows for precise control of the amount of adhesive poured in and enables concentric sealing of the membrane fiber 100 and the connector. The other end of the membrane fiber 100 can be sealed using the same method. The sealed membrane fiber 100 has a rigid tube connector, which can be connected to other pipes via a quick-clamp fitting.

[0019] Preferably, the positioning tube 2 has two preferred structures that can be selected for implementation:

[0020] like Figure 1 As shown, in the first preferred structure, the positioning tube 2 is a gradually converging tapered shape. Due to the tapered diameter characteristic, it can seamlessly adapt to membrane fibers 100 of various diameters for encapsulation. However, a certain degree of accuracy is required during the cutting process.

[0021] like Figure 2As shown, or in a second preferred structure, the positioning tube 2 has several stepped holes from top to bottom. Each stepped hole corresponds to a membrane filament 100 of a certain diameter, and the cutting does not need to be particularly precise. However, the number of membrane filament 100 diameters that can be accommodated is limited.

[0022] To facilitate accurate cutting to match the diameter of the membrane filament 100, preferably, the outer wall surface, facing the positioning tube 2, has graduation lines 4 arranged axially. Cutting along these graduation lines will yield the corresponding positioning hole 3 diameter.

[0023] This invention also provides a hollow fiber membrane quick connector, which enables precise and rapid encapsulation of the membrane filaments 100, ensuring concentric encapsulation and uniform glue application. The variable diameter structure of the positioning tube 2 can adapt to different membrane filament diameters, providing strong adaptability. It is low in cost, simple to manufacture, and can be used as a disposable consumable.

[0024] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
