[0025] 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.

[0026] Reference Figures 1-3 This utility model provides an embodiment of a filter housing with a double-sealed structure, comprising a filter housing body 1, a cover plate 3 on the upper part of the filter housing body 1, sliding plates 6 slidably connected to the inner sides of the cover plate 3, a connecting plate 7 fixedly connected to the lower part of the sliding plates 6, and an installation assembly for installing the cover plate 3 on the outer middle part of the filter housing body 1. The installation assembly includes an installation ring 9, which is fixedly connected to the outer middle part of the filter housing body 1. A sliding groove 10 is formed on the upper part of the installation ring 9, and installation slots 11 are formed on the front and rear sides of the upper part of the installation ring 9. The sliding groove 10 slides inside the sliding groove 10. A limiting block 8 is connected, and a bolt 12 is inserted inside the limiting block 8. A nut 13 is threaded to the outside of the bolt 12. The bolt 12 passes through the mounting ring 9. The limiting block 8 is fixedly connected to the connecting plate 7 on the side away from it. The lower part of the connecting plate 7 is slidably connected to the inside of the slide groove 10. A sealing assembly is provided on the upper part of the outer side of the filter housing body 1 for sealing the filter housing. The sealing assembly includes a sealing sleeve 2, which is fixedly connected to the upper outer side of the filter housing body 1. A sealing gasket 4 is fixedly connected to the lower part of the cover plate 3. A handle 5 is fixedly connected to the upper middle part of the cover plate 3. The sealing gasket 4 is slidably connected to the inner wall of the filter housing body 1.

[0027] When the filter housing needs to be sealed, first push the connecting plate 7 so that it drives the sliding plate 6 to slide smoothly into the cover plate 3. Then push the handle 5 so that the cover plate 3 moves into the sealing sleeve 2. At this time, the cover plate 3 will drive the sealing gasket 4 to slide into the filter housing body 1. The cover plate 3 drives the connecting plate 7 to move forward through the sliding plate 6. At the same time, the sliding plate 6 also drives the connecting plate 7 to move synchronously. The connecting plate 7 then drives the limiting block 8 to slide into the slide groove 10 through the mounting groove 11. Turn the handle 5 to drive the cover plate 3 to rotate. The cover plate 3 drives the connecting plate 7 to rotate through the sliding plate 6. The connecting plate 7 drives the limiting block 8 to rotate and move to the left and right sides inside the slide groove 10. Finally, push the bolt 12 so that it passes through the limiting block 8 and the mounting ring 9. Then tighten the bolt 12 by turning the nut 13, thereby completing the entire sealing process. This achieves a complete seal with a double sealing structure for the filter housing, which is convenient for disassembly and maintenance, and improves the maintenance efficiency of the filter.

[0028] Reference Figures 1-3 The filter housing 1 is made of stainless steel, the cover plate 3 is made of polypropylene, and the sliding plate 6 is made of polytetrafluoroethylene.

[0029] By using stainless steel to improve the strength and corrosion resistance of the filter housing body 1, the filter housing can maintain long-term stability and reliability in harsh working environments. By using polypropylene to ensure the corrosion resistance and high-temperature resistance of the cover plate 3, the stability and durability of the cover plate 3 in long-term use are ensured. By using polytetrafluoroethylene to ensure the chemical resistance and low friction of the sliding plate 6, friction loss can be effectively reduced during sliding, preventing material damage caused by chemical reactions or high friction, thereby ensuring the smooth operation of the sliding plate 6 for a long time. This improves the service life of the filter housing and enhances its adaptability to various harsh environments.

[0030] Working principle: When the filter housing needs to be sealed, push the connecting plate 7 to make the sliding plate 6 slide into the cover plate 3. Push the handle 5 to make the cover plate 3 move into the sealing sleeve 2. The cover plate 3 makes the sealing gasket 4 slide into the filter housing body 1, and at the same time, it makes the sliding plate 6 move. The sliding plate 6 makes the connecting plate 7 move. The connecting plate 7 makes the limiting block 8 slide into the slide groove 10 through the mounting groove 11. Turn the handle 5 to make the cover plate 3 rotate. The cover plate 3 makes the connecting plate 7 rotate through the sliding plate 6. The connecting plate 7 makes the limiting block 8 rotate to the left and right sides inside the slide groove 10. Finally, push the bolt 12 to pass through the limiting block 8 and the mounting ring 9. Turn the nut 13 to tighten the bolt 12. This realizes that the filter housing with double sealing structure is easy to disassemble and assemble, and improves the maintenance efficiency of the filter.
