Description

Technical Field

[0001] This utility model relates to the field of gas purification equipment, and in particular to an installation device for a hydrogen purification membrane module. Background Technology

[0002] Hydrogen purification membrane modules are key components in the hydrogen energy industry chain, widely used in fuel cell hydrogen supply systems, industrial hydrogen production equipment, and high-purity hydrogen preparation devices. Their main function is to efficiently separate and purify hydrogen from mixed gases containing impurities (such as nitrogen, oxygen, water vapor, and hydrocarbons) using the principle of selective permeation, thereby obtaining high-purity or even ultrapure hydrogen.

[0003] Existing hydrogen purification membrane modules typically need to be connected to external gas supply pipelines or downstream hydrogen-using units. Common connection methods include threaded connections and flange connections. Threaded or flange connections rely on gaskets or O-rings for sealing. During long-term operation, these connections are prone to seal failure due to vibration, thermal expansion and contraction, or material aging, leading to hydrogen leakage and posing safety hazards. Furthermore, under conditions of frequent equipment start-ups and shutdowns or operating environments with mechanical vibration, the structure is prone to loosening, affecting system stability, purification efficiency, and causing further safety risks. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an installation device for a hydrogen purification membrane module, which aims to solve the problem that the connection structure is prone to loosening due to frequent equipment start-ups and shutdowns or mechanical vibrations in the operating environment in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an installation device for a hydrogen purification membrane assembly, comprising a connecting tail sleeve and a connecting sleeve, wherein the connecting sleeve is fitted onto the outer periphery of the right end of the connecting tail sleeve, and a ring is coaxially fixedly connected to the right end face of the connecting tail sleeve; an inner circular groove is formed on the outer peripheral surface of the connecting tail sleeve on the left side of the ring; a protrusion protruding towards the axis is provided on the left side of the inner wall of the connecting sleeve, the protrusion and the connecting sleeve are integrally formed, the protrusion is embedded in the inner circular groove, an injection hole is formed on the tube wall of the connecting sleeve, a pipeline passes through the inner cavity of the connecting tail sleeve and the connecting sleeve, and an annular gap is formed in the internal space of the connecting sleeve.

[0006] As a further description of the above technical solution: the axial thickness of the protrusion is equal to the axial width of the inner circular groove.

[0007] As a further description of the above technical solution: the right end face of the protrusion is in close contact with the right side wall of the inner circular groove.

[0008] As a further description of the above technical solution: the connecting sleeve and the protrusion are both made of elastic rubber material.

[0009] As a further description of the above technical solution: the outer surface of the connecting sleeve is patterned.

[0010] As a further description of the above technical solution: the ring is located on the right side of the protrusion.

[0011] As a further description of the above technical solution: the injection hole is injected with vulcanized adhesive through an injection process, and after the vulcanized adhesive is cured, it covers the outer peripheral surface of the pipeline and adheres to the inner wall of the connecting sleeve.

[0012] As a further description of the above technical solution: the right end of the pipeline extends to the outside of the connecting sleeve and beyond the right end face of the connecting sleeve.

[0013] This utility model has the following beneficial effects: 1. In this utility model, by setting an inner circular groove on the connecting tail sleeve and setting an integrally formed protrusion on the inner wall of the connecting sleeve, the two can achieve rapid axial positioning and pre-fixation by snap-fitting.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 1 and Figure 2 The present invention provides an embodiment of an installation device for a hydrogen purification membrane assembly, comprising a connecting tail sleeve 10 and a connecting sleeve 20. The connecting sleeve 20 is fitted onto the outer periphery of the right end of the connecting tail sleeve 10, and the outer surface of the connecting sleeve 20 is provided with a pattern 201 to improve the hand grip friction and anti-slip performance during assembly operations.

[0019] Reference Figure 2 and Figure 3 A ring 101 is coaxially fixed to the right end face of the connecting tail sleeve 10. An inner circular groove 102 is formed on the outer circumferential surface of the connecting tail sleeve 10 on the left side of the ring 101. A protrusion 103 protruding in the axial direction is provided on the left side of the inner wall of the connecting sleeve 20. The ring 101 is located to the right of the protrusion 103 to limit the axial displacement of the connecting sleeve 20 to the right after assembly, which has a good anti-disengagement effect. The axial thickness of the protrusion 103 is equal to the axial width of the inner circular groove 102 to achieve seamless axial connection. The protrusion 103 and the connecting sleeve 20 are integrally formed. The protrusion 103 is embedded in the inner circular groove 102 to achieve axial locking and positioning between the connecting sleeve 20 and the connecting tail sleeve 10. The right end face of the protrusion 103 is tightly fitted with the right side wall of the inner circular groove 102 to form a stop and limit structure to prevent the connecting sleeve 20 from coming off to the right. Both the connecting sleeve 20 and the protrusion 103 are made of elastic rubber material, and the elastic deformation of the material is used to achieve interference fit and sealing fit during assembly.

[0020] Reference Figure 2 and Figure 3 The connecting sleeve 20 has an injection hole 104 on its tube wall. The connecting tail sleeve 10 and the inner cavity of the connecting sleeve 20 pass through the pipe 30. The inner space of the connecting sleeve 20 forms an annular gap 105. The vulcanizing adhesive can be injected into the annular gap 105 between the inner wall of the connecting sleeve 20 and the pipe 30 passing through it through the injection hole 104.

[0021] Reference Figure 2 and Figure 3The injection hole 104 is filled with vulcanized adhesive through the injection process. After the vulcanized adhesive is cured, it covers the outer peripheral surface of the pipe 30 and is bonded to the inner wall of the connecting sleeve 20, forming a connection structure that integrates sealing, fixing and shock resistance. The right end of the pipe 30 extends to the outside of the connecting sleeve 20 and exceeds the right end face of the connecting sleeve 20, so as to facilitate docking or connection with other components.

[0022] Working principle: When in use, first hold the connecting sleeve 20 by the pattern 201 on the outer surface and push it to the left. Since the connecting sleeve 20 and the protrusion 103 are made of elastic rubber material, the protrusion 103 will undergo elastic deformation under the pushing force, allowing it to pass over the ring 101 on the connecting sleeve 10. When the protrusion 103 moves to the position corresponding to the inner circular groove 102, it quickly embeds into the inner circular groove 102 under its own elastic restoring force. At this time, the right end face of the protrusion 103 is tightly fitted with the right side wall of the inner circular groove 102, while the ring 101 is located on the right side of the protrusion 103, forming a stop and limit structure to prevent the connecting sleeve 20 from coming off to the right in subsequent use, thus completing the initial mechanical connection and sealing.

[0023] Subsequently, the pipe 30 to be connected is inserted from the right end of the connecting sleeve 20 until its left end contacts the inside of the connecting tail sleeve 10 or reaches a predetermined depth. Then, the injection hole 104 is connected through a dedicated dispensing device, and liquid vulcanized adhesive is injected into the annular gap 105 formed between the inner wall of the connecting sleeve 20 and the outer wall of the pipe 30. The injected vulcanized adhesive will fill the entire annular gap 105 and completely wrap the pipe 30. After the vulcanized adhesive is left to cure at room temperature for a period of time, it will form a strong chemical bond with the outer surface of the pipe 30 and the inner wall of the connecting sleeve 20, thereby integrating the connecting tail sleeve 10, the connecting sleeve 20 and the pipe 30 into a whole. This achieves tight positioning of the pipe 30, reduces the risk of loosening or breakage caused by vibration, and forms a sealing layer to prevent moisture, dust and other pollutants in the external environment from entering the hydrogen purification membrane module, ensuring long-term stable operation.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
