Description

Technical Field

[0001] This utility model relates to the field of filters, and in particular to modular molecular sieve filters for gas separation. Background Technology

[0002] Gas separation filters are devices specifically designed to separate, purify, or remove specific components from gas mixtures, and are widely used in industries such as industry, medicine, environmental protection, and energy. Their core function is to achieve efficient separation and purification of target gases through technologies such as physical adsorption, molecular sieving, chemical reactions, or membrane separation. Filters effectively capture dust, fumes, and other fine particles from air or process gases, preventing these impurities from entering downstream equipment or affecting the quality of the final product. For gas streams containing aerosols or droplets, filters can separate these droplets, ensuring a dry and pure gas output. By removing harmful substances such as toxic gases, microorganisms, or other potentially hazardous components, filters not only protect operator safety but also provide a healthier workplace environment. Molecular sieve filter elements play the role of the core separation medium in gas separation filters; their unique microporous structure and surface properties enable them to efficiently and selectively adsorb specific gas molecules, thereby achieving the separation and purification of gas mixtures.

[0003] However, conventional gas separation filters present the problem of inconvenience in disassembling and assembling molecular sieve filter elements when replacing them. Therefore, a modular molecular sieve filter for gas separation is provided. Summary of the Invention

[0031] This embodiment provides a modular molecular sieve filter for gas separation, including a mounting shell 1, a mounting shaft a12 fixedly mounted on the side wall of the mounting shell 1, a filter cavity 11 opened on the upper surface of the mounting shell 1, a support groove 111 opened on the side wall of the filter cavity 11, a sealing groove 112 opened on the lower surface of the support groove 111, a support plate 114 slidably mounted in the sealing groove 112, a shell cover 2 inserted into the upper end of the mounting shell 1, a mounting shaft b22 fixedly mounted on the side wall of the shell cover 2, and further including: a locking mechanism 3, the locking mechanism 3 including at least a mounting ring 31, the mounting ring 31 being rotatably mounted on the mounting shaft a12, a support rod 32 fixedly mounted on one side of the arc wall of the mounting shaft a12, and a pressure block 321 rotatably mounted on the other end of the support rod 32, the pressure block 321 pressing the mounting shaft b22 to fix the position of the shell cover 2;

[0032] like Figure 4 , Figure 9 , Figure 10 As shown, the locking mechanism 3 also includes a connecting rod 33, which is fixedly installed on the arc wall of the mounting ring 31. A telescopic groove 331 is provided on the upper surface of the connecting rod 33, and a telescopic rod 332 is slidably installed in the telescopic groove 331. A pressure groove 333 is provided through the side wall of the telescopic rod 332 near the edge of the upper surface.

[0033] like Figure 10 As shown, a return spring 334 is fixedly installed at the bottom of the telescopic groove 331, and the other end of the return spring 334 is fixedly installed on the lower surface of the telescopic rod 332. In the initial state, the return spring 334 is not stretched, and the height of the upper surface of the pressure groove 333 is lower than the height of one end of the pressure block 321. After the telescopic rod 332 is pulled upward, one end of the pressure block 321 is inserted into the pressure groove 333, and the return spring 334 is reset to drive the pressure groove 333 to squeeze the pressure block 321. The pressure block 321 squeezes the mounting shaft b22 to fix the position of the cover 2, thereby realizing the quick closing of the cover 2.

[0034] like Figure 6 , Figure 9As shown, a limiting groove 221 is provided at the arc wall of the mounting shaft b22. The middle part of the pressure block 321 has an arc-shaped structure. The inner arc wall of the pressure block 321 fits against the arc wall of the limiting groove 221. One end of the pressure block 321 is inserted into the pressure groove 333. The return spring 334 pulls the telescopic rod 332 downward. The telescopic rod 332 presses the pressure block 321 downward through the pressure groove 333. The pressure block 321 squeezes the mounting shaft b22 to fix the position of the cover 2, thereby realizing the quick fixation of the cover 2.

[0035] like Figure 1 , Figure 8 As shown, a hinge 121 is fixedly installed on the arc wall of the mounting shell 1 near the edge of the upper surface. The other end of the hinge 121 is fixedly installed on the side wall of the shell cover 2. The mounting shell 1 and the shell cover 2 are rotatably connected by the hinge 121 so that the shell cover 2 can be opened and closed.

[0036] like Figure 2 , Figure 7 As shown, a molecular sieve filter element 13 is inserted and installed in the filter chamber 11. A limiting block 131 is fixedly installed on the edge of the upper surface of the arc wall of the molecular sieve filter element 13. The lower surface of the limiting block 131 is in contact with the upper surface of the support groove 111. An annular sealing block 132 is fixedly installed on the lower surface of the limiting block 131. The sealing block 132 is inserted and installed in the sealing groove 112. The limiting block 131 is inserted into the sealing groove 112 to maintain the sealing of the molecular sieve filter element 13 during filtration. The molecular sieve filter element 13 adsorbs specific gas molecules through its microporous structure and surface characteristics, thereby realizing the separation and purification of mixed gases.

[0037] like Figure 3 , Figure 5 As shown, a support spring 113 is fixedly installed at the bottom of the sealing groove 112, and the other end of the support spring 113 is fixedly installed on the lower surface of the support plate 114. When the shell cover 2 is opened, the support spring 113 is reset to push the support plate 114 to move upward, thereby pushing one end of the molecular sieve filter element 13 to extend out, so as to remove the molecular sieve filter element 13 for replacement.

[0038] like Figure 2 , Figure 6 As shown, a connecting cavity 21 is provided inside the shell cover 2. The connecting cavity 21 is aligned vertically with the filter cavity 11. A sealing ring 23 is fixedly installed on the lower surface of the shell cover 2. The sealing ring 23 is inserted into the support groove 111. The lower surface of the sealing ring 23 is in contact with the upper surface of the molecular sieve filter element 13 to fix the position of the molecular sieve filter element 13 and at the same time maintain the sealing of the filter cavity 11.

[0039] In practical use, after pulling the telescopic rod 332 upward, the pressure block 321 is rotated to open the rotating cover 2. The support spring 113 in the sealing groove 112 resets, pushing the support plate 114 upward, thereby pushing one end of the molecular sieve filter element 13 out for easy removal and replacement. After inserting the new molecular sieve filter element 13 into the filter chamber 11, the limiting block 131 of the molecular sieve filter element 13 is inserted into the support groove 111, and the sealing block 132 on the lower surface of the limiting block 131 is inserted into the sealing groove 112. The sealing block 132 pushes the support plate 114 upward. The support spring 113 is moved down and compressed. The cover 2 is rotated so that the sealing ring 23 is inserted into the support groove 111 to achieve a seal in the filter chamber 11. The pressure block 321 is rotated so that the inner arc wall of the pressure block 321 fits against the arc wall of the limiting groove 221, so that one end of the pressure block 321 is inserted into the pressure groove 333. The return spring 334 pulls the telescopic rod 332 down. The telescopic rod 332 presses the pressure block 321 down through the pressure groove 333. The pressure block 321 squeezes the mounting shaft b22 to fix the position of the cover 2, so as to realize the quick replacement of the molecular sieve filter element 13 and simplify the operation steps when replacing the molecular sieve filter element 13.
