[0003] In current technologies, the double-layer membrane shell structure is prone to deformation due to pressure in high-pressure water treatment scenarios, affecting the normal operation of the membrane element; and in the separation of chemical substances, the non-corrosion-resistant membrane shell will shorten its service life. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art where single-layer membrane shells are easily deformed by pressure in high-pressure water treatment scenarios, affecting the normal operation of membrane elements; and where non-corrosion-resistant membrane shells shorten the service life during chemical separation. The invention proposes a double-layer material structure membrane shell end.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a double-layer material structure membrane shell end, including a shell, both ends of which are equipped with through end plate welding parts, one of which has an end plate body installed inside, one end of which is fixed with a central tube body, and one end of which is fixed with an end face side tube on one side of the central tube body; the other has a blind end plate internally threaded to it, one end of which is fixed with a blind central tube; the shell is provided with an inner cylinder, and an outer cylinder is fixed to the outer wall of the inner cylinder.

[0006] Preferably, a reinforcing ring is fixed on the inner wall of one of the end plate welded parts, and the end plate body is installed inside the reinforcing ring.

[0007] Preferably, a retaining ring post is fixed to the other end of the end plate body, and a retaining ring body is fixed to the end of the retaining ring post away from the end plate body.

[0008] Preferably, two membrane fastening strap assemblies are installed on the outer wall of the housing.

[0009] Preferably, a handle is fixed to one end of the blind end plate.

[0010] Preferably, an adapter assembly is installed at the opposite end of both the blind end plate and the central tube body.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the device employs a double-layer structure consisting of an inner and outer cylinder, which enhances performance in terms of pressure resistance and heat insulation. The double-layer material structure integrates the advantages of different materials: the outer cylinder uses a high-strength material to enhance pressure resistance, while the inner cylinder uses a corrosion-resistant material to resist chemical erosion, thereby improving overall performance. From an economic perspective, simply using high-performance materials to manufacture the membrane shell would significantly increase costs. The double-layer material structure allows for the use of high-performance materials in critical areas, while other parts can use lower-cost materials, controlling costs while ensuring performance. Furthermore, a well-designed double-layer membrane shell can reduce maintenance and replacement frequency, improve equipment operating efficiency, lower long-term operating costs, and strengthen the local strength of the membrane shell, thus improving pressure resistance.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1, such as Figure 1-4As shown, this utility model provides a double-layer material structure membrane shell end, including a shell 1. Both ends of the shell 1 are equipped with through end plate welding parts 3. One of the through end plate welding parts 3 is equipped with an end plate body 9. One end of the end plate body 9 is fixed with a central tube body 7. One end of the end plate body 9 is located on one side of the central tube body 7 and is fixed with an end face side tube 8. The other through end plate welding part 3 is internally threaded with a blind end plate 12. One end of the blind end plate 12 is fixed with a blind central tube 2. The shell 1 is provided with an inner cylinder 16. An outer cylinder 15 is fixed on the outer wall of the inner cylinder 16.

[0021] The overall effect of Embodiment 1 is as follows: the through-end plate welded component 3 is used to connect different parts of the membrane shell, ensuring the stability of the overall structure; the blind center tube 2, blind end plate 12, etc., can play the role of sealing and isolating parts of the space; the adapter assembly 4 is used to adapt the connection between different components; the end face side pipe 8 is used to connect to the external pipeline, realizing the inflow and outflow of the medium. This device forms a double-layer structure with an inner cylinder 16 and an outer cylinder 15, which can enhance the performance of pressure resistance and heat insulation. The double-layer material structure can integrate the advantages of different materials. The outer cylinder 15 uses a high-strength material to enhance pressure resistance, and the inner cylinder 16 uses a corrosion-resistant material to resist chemical erosion, thereby improving the overall performance. From an economic point of view, simply using high-performance materials to make the membrane shell would significantly increase the cost. The double-layer material structure allows the use of high-performance materials in key parts, while other parts use lower-cost materials, controlling costs while ensuring performance. Moreover, a well-designed double-layer membrane shell can reduce the frequency of maintenance and replacement, improve equipment operating efficiency, and reduce long-term operating costs.

[0022] Example 2, as Figure 1-4 As shown, a reinforcing ring 14 is fixed on the inner wall of one of the through end plate welding parts 3, the end plate body 9 is installed in the reinforcing ring 14, a retaining ring post 10 is fixed on the other end of the end plate body 9, a retaining ring body 11 is fixed on the end of the retaining ring post 10 away from the end plate body 9, two membrane fastening strap assemblies 6 are installed on the outer wall of the housing 1, a handle 13 is fixed on one end of the blind end plate 12, and an adapter assembly 4 is installed on the opposite ends of the blind end plate 12 and the central tube body 7.

[0023] The overall effect of embodiment 2 is that the reinforcing ring 14 can strengthen the local strength of the membrane shell and improve the pressure resistance. The retaining ring post 10 and the retaining ring body 11 are used to snap the end plate body 9 into the housing 1. The handle 13 makes it easy for the user to rotate the blind end plate 12, which is convenient for installation and disassembly.

[0024] Working Principle: In operation, the through-end plate welding component 3 connects different parts of the membrane shell, ensuring overall structural stability. The blind center tube 2 and blind end plate 12 enclose and isolate certain spaces. The adapter assembly 4 adapts the connections between different components, and the end-side pipe 8 connects to external pipelines, enabling media inflow and outflow. This device features a double-layer structure composed of an inner cylinder 16 and an outer cylinder 15, enhancing pressure resistance and heat insulation. This double-layer material structure integrates the advantages of different materials. The outer cylinder 15 uses high-strength materials to enhance pressure resistance, while the inner cylinder 16 uses corrosion-resistant materials to resist chemical erosion, thus improving overall performance. From an economic perspective, simply using high-performance materials for the membrane shell would significantly increase costs. The double-layer material structure allows for the use of high-performance materials in critical areas, while other parts can use lower-cost materials, controlling costs while ensuring performance. Furthermore, a well-designed double-layer membrane shell reduces maintenance and replacement frequency, improves equipment operating efficiency, and lowers long-term operating costs.
