Description

Technical Field

[0001] This utility model relates to the field of inorganic membranes, and in particular to an inorganic membrane anti-seepage installation and sealing assembly. Background Technology

[0002] Continuous flow membranes are asymmetric porous membrane materials made by mixing and extruding inorganic ceramic materials such as alumina and zirconium oxide, followed by high-temperature sintering. Continuous flow membranes have small pore sizes and can achieve molecular-level filtration, making them widely used in the filtration field.

[0003] In inorganic membrane filtration equipment, multiple stepless membrane materials need to be installed. In order to seal the joints, sealing rings and cover plates are also required. The cover plates are used to uniformly press the sealing rings at the ends of multiple stepless membrane materials. This requires high assembly precision, increases the difficulty of maintenance, and makes it impossible to replace the sealing rings or stepless membrane materials individually. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide an inorganic membrane anti-seepage installation and sealing component to ensure sealing effect and improve maintenance convenience.

[0005] To achieve this objective, the present invention adopts the following technical solution: An inorganic membrane seepage-proof sealing assembly includes: a cylinder, flanges, an inorganic membrane, an elastic seal, and a threaded sleeve. The flanges are disposed at both ends of the cylinder, and the inorganic membranes are spaced apart within the cylinder. Baffles are provided at both ends of the inorganic membranes within the flanges. Positioning holes corresponding to the inorganic membranes are provided on the inner side of each baffle, and threaded holes corresponding to the positioning holes are provided on the outer side of each baffle. A tapered hole connects the threaded hole and the positioning hole. The elastic seal includes an outer tapered sleeve, a first straight sleeve, and a second straight sleeve. The outer tapered sleeve is disposed within the tapered hole. The first straight sleeve is concentrically disposed at the inner end of the outer tapered sleeve and extends inward into the positioning hole. The second straight sleeve is concentrically disposed at the outer end of the outer tapered sleeve and extends outward into the threaded hole. The threaded sleeve is disposed within the threaded hole to compress the second straight sleeve.

[0006] The outer end of the threaded sleeve is provided with an external hexagonal sleeve.

[0007] The outer conical sleeve, the first cylindrical sleeve, and the second cylindrical sleeve are made of an integrated rubber structure.

[0008] The positioning holes are arranged in a ring array on the baffle.

[0009] A filter pipe connector is provided on one side of the cylinder.

[0010] The flange edge is provided with mounting holes at intervals.

[0011] The baffle and flange are either integrated or welded together.

[0012] The beneficial effects of this utility model are as follows: An inorganic membrane anti-seepage installation and sealing assembly positions the end of the inorganic membrane through a positioning hole on a baffle, and seals the outer end of the inorganic membrane by extending a first straight sleeve into the positioning hole. A second straight sleeve can also be squeezed by a threaded sleeve to ensure contact between the outer conical sleeve and the outer circle of the inorganic membrane and the inner wall of the conical hole, improving sealing performance. Furthermore, the elastic deformation of the second straight sleeve can cover the edge of the inorganic membrane end, further enhancing sealing performance and preventing leakage. It is quick to assemble and disassemble; after removing the threaded sleeve, the inorganic membrane or elastic seal can be replaced individually. It has good adaptability to the processing precision of the inorganic membrane and elastic seal, and is easy to maintain. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 yes Figure 1 A magnified view of part A in the middle. Detailed Implementation

[0014] The following is combined with Figures 1 to 2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0015] like Figure 1 and Figure 2 The inorganic membrane leak-proof sealing assembly shown includes: a cylinder 1, flanges 4, an inorganic membrane 2, an elastic seal 7, and a threaded sleeve 13. The flanges 4 are located at both ends of the cylinder 1 and are welded and fixed, resulting in a robust structure. The flanges 6 have mounting holes 5 spaced along their edges for convenient connection to corresponding pipes. One flange 4 at one end of the cylinder 1 is connected to the raw liquid pipe to introduce the raw liquid, while the flange at the other end of the cylinder 1 is connected to the concentrate pipe to discharge the concentrated waste liquid.

[0016] A filtrate pipe connector 3 is provided on one side of the cylinder 1. The filtrate pipe connector 3 is connected to the filtrate pipe to deliver the clear liquid filtered by the inorganic membrane 2 to the filtrate pipe.

[0017] like Figure 1 As shown, the inorganic membranes 2 are spaced apart in the cylinder 1. The flange 4 is provided with baffles 6 located at both ends of the inorganic membranes 2. The baffles 6 and the flange 4 adopt an integrated structure or a welded fixed structure, which is sturdy and has a good anti-seepage effect.

[0018] Positioning holes 15, corresponding one-to-one with the inorganic membranes 2, are provided on the inner side of the baffle 6 for positioning the two ends of the inorganic membranes 2. In this embodiment, the positioning holes 15 are arranged in a ring array on the baffle 6 to achieve positioning of multiple inorganic membranes 2.

[0019] like Figure 2 As shown, the outer side of the baffle 6 is provided with threaded holes 9 corresponding one-to-one with the positioning holes 15. A tapered hole 8 is provided between the threaded holes 9 and the positioning holes 15, which facilitates processing. In this embodiment, the elastic seal includes an outer tapered sleeve 11, a first straight sleeve 10, and a second straight sleeve 12. The outer tapered sleeve 11 is disposed in the tapered hole 8, and the first straight sleeve 10 is concentrically disposed at the inner end of the outer tapered sleeve 11 and extends inward into the positioning hole 15 to seal the outer circular end of the inorganic membrane 2.

[0020] The second straight sleeve 12 is concentrically disposed at the outer end of the outer conical sleeve 11 and extends outward into the threaded hole 9. The threaded sleeve 13 is disposed in the threaded hole 9 to compress the second straight sleeve 12, thereby causing the outer conical sleeve 11 to undergo elastic deformation.

[0021] In this embodiment, the outer end of the threaded sleeve 13 is provided with an external hexagonal sleeve 14, which facilitates rotation of the external hexagonal sleeve 14 using a wrench, thereby rotating the threaded sleeve 13 within the threaded hole 9, making disassembly and assembly convenient. The external conical sleeve 11, the first cylindrical sleeve 10, and the second cylindrical sleeve 12 adopt an integrated rubber structure, ensuring good integrity and preventing cracking and leakage. Furthermore, after disassembly, the threaded sleeve 13 allows for individual replacement of the inorganic membrane 2 or the elastic seal 7, offering good adaptability to the machining precision of the inorganic membrane 2 and the elastic seal 7, and facilitating maintenance.

[0022] Tightening the screw sleeve 13 compresses the second straight sleeve 12, ensuring the elastic deformation of the outer conical sleeve 11 and its tight contact with the outer circle of the inorganic membrane 2 and the inner wall of the conical hole 8, thus improving the sealing performance. Figure 2 As shown, the elastic deformation of the second straight sleeve 12 can be used to cover the edge of the inorganic membrane 2, further improving the sealing performance and avoiding leakage problems.

[0023] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
