Technical Field

[0001] The utility model relates to the field of compressed air filtration, in particular to a compressed air filter housing. Background Art

[0002] As we all know, the compressed air filter housing is a device used to hold and protect the compressed air filter. The main function of the compressed air filter housing is to provide a stable installation environment to ensure that the filter can work properly. It can also prevent foreign impurities and pollutants from entering the filter, thereby ensuring the filtering effect. In addition, the filter housing is usually equipped with an inlet and outlet to facilitate the connection of the air source and the air-using equipment.

[0003] The prior art CN217795157U disclosed a compressed air filter housing, including a housing and a housing cover detachably connected to the top of the housing, the housing cover is connected to the housing, the inner wall of the housing cover is fixedly connected to a baffle, the baffle divides the housing cover and the interior of the housing into a first cavity and a second cavity, and the housing cover is fixedly connected to an air inlet pipe and an air outlet pipe. The inner scraper ring of the utility model can scrape the outer wall of the filter element, thereby scraping off the debris on the outer wall of the filter element, effectively avoiding the blockage caused by excessive impurities adhering to the surface of the filter element.

[0004] However, in actual application, the existing compressed air filter housing is not convenient for people to disassemble and maintain between the housing and the cover, which makes the compressed air filter housing relatively poor in convenience, maintainability and disassembly during installation and maintenance, affecting the efficiency of subsequent disassembly and maintenance; and the housing and the cover are prone to looseness after installation, resulting in poor sealing between the housing and the cover, affecting subsequent stable use. To this end, the utility model proposes a compressed air filter housing. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a compressed air filter housing.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-4A compressed air filter housing comprises a housing 1 for accommodating and protecting a compressed air filter, and a housing cover 2, a connector 3 is fixedly connected to the bottom of the housing 1, a connecting pipe 4 is fixedly connected to the top of the housing cover 2, a connecting groove 300 is provided at the bottom of the connector 3, and the connecting pipe 4 is installed in the connecting groove 300 by threading; a sealing ring 5 is movably provided in the connecting groove 300, a sealing sliding pipe 6 is fixedly connected to the top of the sealing ring 5, the top end of the sealing sliding pipe 6 slides through the housing 1 and is fixedly connected to a sealing sliding ring 7, a sealing sliding sleeve 8 is fixedly sleeved on the circumferential inner wall of the housing 1, and the sealing sliding ring 7 is sealingly slidably sleeved in the sealing sliding sleeve 8 along the vertical direction;

[0026] Grooves 302 are provided on the inner walls on both sides of the connecting groove 300, and the top two ends of the sealing ring 5 are rotatably connected with inclined rotating connecting rods 9, and the inclined top end of the rotating connecting rod 9 is rotatably connected with a sliding seat 10, and the top of the sliding seat 10 is slidably installed on the top inner wall of the groove 302; a fixed seat 14 is fixedly installed on the top inner wall of the groove 302, a guide rod 13 is fixedly connected between the fixed seat 14 and the side wall of the groove 302, and the sliding seat 10 is slidably sleeved on the guide rod 13 in the horizontal direction; an elastic spring 11 sleeved on the guide rod 13 is fixedly connected between the sliding seat 10 and the side wall of the groove 302.

[0027] In this embodiment, a tension spring 12 sleeved on the guide rod 13 is fixedly connected between the fixed seat 14 and the sliding seat 10; an external thread 401 is provided on the outer wall of the connecting tube 4, and an internal thread 301 is provided on the inner wall of the connecting groove 300, and the connecting tube 4 is threadedly connected to the internal thread 301 on the inner wall of the connecting groove 300 through the external thread 401.

[0028] In this embodiment, a rubber sealing ring 501 is fixedly connected to the bottom of the sealing ring 5 , and the sealing ring 5 is in sealing contact with the top port of the connecting pipe 4 through the rubber sealing ring 501 .

[0029] Among them, a slide groove is provided on the top inner wall of the groove 302, a slider 15 is provided on the top of the slide seat 10, and the slider 15 is slidably installed in the slide groove along the horizontal direction; a guide hole is provided on the slide seat 10, and the slide seat 10 is slidably sleeved on the guide rod 13 along the horizontal direction through the guide hole.

[0030] like Figure 1-4The compressed air filter housing shown in the figure is convenient for disassembling and assembling the housing cover 2 on the housing 1 so as to inspect and maintain the compressed air filter component in the housing 1. When disassembly is required, it is only necessary to thread the connecting pipe 4 on the top of the housing cover 2 and the connecting groove 300 on the bottom connector 3 of the housing 1, thereby loosening the external thread 401 on the connecting pipe 4 and the internal thread 301 on the inner wall of the connecting groove 300, so that the connecting pipe 4 can be threadedly removed from the connecting groove 300, so that the housing cover 2 on the housing 1 can be quickly removed for inspection and maintenance of the filter component in the housing. After the inspection and maintenance, the connecting pipe 4 on the shell cover 2 and the connecting groove 300 on the connecting head 3 are rotated in the opposite direction, so that the external thread 401 on the connecting pipe 4 and the internal thread 301 on the inner wall of the connecting groove 300 can be threadedly locked and installed; and during the installation process, the top port of the connecting pipe 4 will cause the rubber sealing ring 501 and the sealing ring 5, the sealing sliding pipe 6, and the sealing sliding ring 7 to move upward as a whole. When the sealing ring 5 moves upward, it will drive the slide 10 to move outward by rotating the connecting rod 9 and squeeze the elastic spring 11. At the same time, when the slide 10 moves outward, it also stretches the tension spring 12. In this way, the elastic spring 11 will produce an elastic reaction after being squeezed, and at the same time, the tension spring 12 also produces a pulling force on the slide 10, and then under the elastic reaction of the elastic spring 11 and the tension spring 12, the slide 10 can be urged to move inward. The rubber sealing ring 501 at the bottom of the sealing ring 5 is moved, and then the connecting rod 9 is rotated to push the sealing ring 5 and the rubber sealing ring 501 to generate a downward thrust, so that the rubber sealing ring 501 at the bottom of the sealing ring 5 can be tightly contacted with the top port of the connecting pipe 4, so that the external thread 401 on the connecting pipe 4 and the internal thread 301 on the inner wall of the connecting groove 300 can be threadedly connected more tightly, and finally it can ensure that the connection between the connecting pipe 4 at the top of the shell cover 2 and the connecting head 3 at the bottom of the shell 1 is more secure, which greatly ensures the sealing after installation, which not only improves the convenience and disassembly of the compressed air filter shell during installation and maintenance, but also improves the efficiency of disassembly and maintenance, and the shell and the cover are not prone to loosening after installation, which ensures that the sealing between the shell and the cover is very good, which is conducive to ensuring subsequent stable use.
