Description

Technical Field

[0001] The utility model relates to an assembly tool, in particular to a membrane component glue injection and casting assembly tool. Background Art

[0002] Hollow fiber membranes are widely used in pharmaceutical, brewing, catering, chemical, municipal wastewater reuse, hospital, community wastewater reuse, papermaking and other production and domestic wastewater treatment industries. It is through membrane separation technology to achieve solution or gas separation, concentration and purification, and the original liquid is passed through the membrane under a certain pressure to achieve material separation and concentration.

[0003] The hollow fiber membrane is injected with glue and cast in the membrane assembly during use. Therefore, in the assembly of the membrane assembly, the glue filling colloid is injected into the assembly shell and changes from liquid to solid to form a support for the hollow fiber membrane. Then, after the edges are cut, it is loaded into the subsequent components for use. In the existing membrane assembly process, after the assembly shell is injected with glue, the liquid glue changes from liquid to solid, which makes it inconvenient to disassemble the assembly and affects the subsequent operations of cutting edges. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a membrane component glue injection and casting assembly tool, which is used for the glue injection process into the component housing, installed at both ends of the component housing, including a sealing ring sleeved on the end of the component housing, a sealing plate covering the outer end surface of the sealing ring, and a sealing hoop arranged on the outer periphery of the sealing ring and the sealing plate, and the sealing hoop tightens the sealing ring and the sealing plate axially.

[0006] Furthermore: the inner wall structure of the sealing ring is a stepped hole structure, which is divided into an orifice sealing part and a glue injection cavity part. The component housing is sealed and plugged into the orifice sealing part. The sealing ring is provided with a glue injection port connected to the glue injection cavity part. The aperture of the glue injection cavity part is smaller than the aperture of the orifice sealing part; the sealing plate covers the orifice of the glue injection cavity part.

[0007] Furthermore, the outer peripheries of the sealing ring and the sealing plate are combined to form an outer conical locking step, and the sealing hoop is provided with an annular inner conical locking groove, which is pressed onto the locking step and tightens the sealing ring and the sealing plate axially.

[0008] Furthermore: a hollow fiber membrane is placed inside the component housing, and casting assembly tools are installed at both ends of the component housing.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model provides a membrane component injection casting assembly tooling by setting a sealing ring and a sealing plate combination structure that is easy to disassemble. On the one hand, it can ensure that the component housing forms a reliable closed environment to facilitate glue injection. At the same time, it is easy to disassemble after glue injection. The sealing ring and the sealing plate are removed from the component housing to facilitate subsequent edge shearing work. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1 , 2 As shown in Figures 3 and 4, a membrane component glue injection casting assembly tool is used for the glue injection process into the component housing 1, installed at both ends of the component housing 1, including a sealing ring 2 sleeved on the end of the component housing 1, a sealing plate 3 covering the outer end surface of the sealing ring 2 and a sealing hoop 4 arranged on the periphery of the sealing ring 2 and the sealing plate 3, and the sealing hoop 4 tightens the sealing ring 2 and the sealing plate 3 along the axial direction.

[0016] The inner wall structure of the sealing ring 2 is a stepped hole structure, which is divided into a hole sealing part 5 and a glue injection cavity part 6. The component housing 1 is sealed and plugged into the hole sealing part 5. The sealing ring 2 is provided with a glue injection port 7 connected to the glue injection cavity part 6. The aperture of the glue injection cavity part 6 is smaller than the aperture of the hole sealing part 5; the sealing plate 3 covers the hole of the glue injection cavity part 6.

[0017] When the membrane assembly is injected with glue, first install the assembly tool at the orifice of the assembly housing 1, and inject glue into the interior of the assembly housing 1 through the injection port 7. The assembly tool can seal the two ends of the assembly housing 1 before the injection begins, so that a closed environment is formed inside. After the internal injection is completed, wait for the glue to cool and form a stable solid inside. Release the sealing hoop 4. After the sealing hoop 4 is removed, separate the sealing ring 2 and the sealing plate 3. At this time, only the sealing ring 2 and the assembly housing 1 are connected as a whole under the action of the solid glue. Because the aperture of the injection cavity 6 is smaller than the aperture of the orifice sealing part 5, the sealing ring 2 can be separated from the glue column formed inside by applying an outward force to the sealing ring 2, thereby completing the separation of the sealing ring 2 and the assembly housing 1. After the separation is completed, the exposed glue column of the assembly housing 1 can be cut off flush with the edge for subsequent assembly.

[0018] The outer peripheries of the sealing ring 2 and the sealing plate 3 are combined to form an outer conical locking step 8, and the sealing hoop 4 is provided with an annular inner conical locking groove 9, which is pressed onto the locking step 8 and tightens the sealing ring 2 and the sealing plate 3 axially.

[0019] The locking groove 9 on the sealing hoop 4 presses the locking step 8. Under the interaction between the outer conical surface and the inner conical surface, a force that directly tightens the sealing plate 3 and the sealing ring 2 to each other can be obtained. This tightening method can ensure that the sealing plate 3 and the sealing ring 2 are reliably fitted and fixed to form a stable whole. When the sealing hoop 4 is released, the axial force formed by the contact between the outer conical surface and the inner conical surface will be immediately eliminated, which is convenient for the disengagement between the sealing plate 3 and the sealing ring 2.

[0020] The hollow fiber membrane is loaded inside the component housing 1, and the casting assembly tooling is installed at both ends of the component housing 1. By setting the assembly tooling at both ends of the component housing 1, and loading the hollow fiber membrane therein, after the internal glue injection, the exposed glue columns at both ends of the component housing 1 are cut off, and at this time, the hollow fiber membrane is wrapped in these glue columns. After the flush cutting is completed, the component formed by the molded hollow fiber membrane and the component housing 1 can be obtained, and the glue column can play a role in stabilizing the hollow fiber membrane, which is convenient for the further installation of the filtering device later.

[0021] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
