However, the sealing cover is usually fixed at the upper end of the filter shell by using a plurality of groups of fixing bolts, so that the sealing cover is difficult to disassemble and assemble.

Description

Technical Field

[0001] The utility model relates to the technical field of fuel gas filters, in particular to a quick-disassembly and quick-assembly structure of a fuel gas filter. Background Art

[0002] Gas filters are widely used in metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electricity, cities, households and other gas-using fields. Gas filters are an indispensable device on the pipeline for conveying medium. They are usually installed at the inlet end of pressure reducing valves, pressure relief valves, positioning valves or other equipment to eliminate impurities in the medium, protect the normal use of valves and equipment, and reduce equipment maintenance costs.

[0003] However, it still has the following disadvantages in actual use:

[0004] When the existing gas filter is in use, since it filters impurities in the gas, after long-term use, the impurities will accumulate inside the gas filter, and the sealing cover needs to be opened to clean the impurities inside. However, the sealing cover is usually fixed to the upper end of the filter housing with multiple sets of fixing bolts, which is difficult to disassemble and install.

[0005] Therefore, a new quick-disassembly and quick-assembly structure of a fuel gas filter is proposed to solve the above problems. Utility Model Content

[0035] See also Figure 1-3 As shown, this embodiment is a quick-disassembly and quick-assembly structure of a gas filter, comprising:

[0036] The filter assembly 1 comprises a connecting pipe 12 and a sealing cover 13;

[0037] The movable assembly 2 comprises a support block 21 fixedly connected to both sides of the upper end of the sealing cover 13, a support rod 22 extending to both sides through the support block 21, a movable rod 23 located on the outer surface of the inner end of the support rod 22, a fixed block 24 fixedly connected to the outer end of the support rod 22, a sealing gasket 25 located at the lower end of the sealing cover 13, and a telescopic spring 26 and a fixing hole 27 fixedly connected to the bottom end of the sealing gasket 25;

[0038] The support block 21 is used to support the support rod 22, the support rod 22 is used to drive the fixed block 24 to move, the movable rod 23 is used to drive the support rod 22 to move through the threaded structure, the fixed block 24 is used to correspond to the fixing hole 27 to fix the sealing cover 13, the sealing gasket 25 is used to seal the bottom end of the sealing cover 13, and the telescopic spring 26 is used to support the sealing gasket 25;

[0039] The filter assembly 1 further comprises a filter housing 11, a connecting pipe 12 is fixedly connected to the outer surfaces of both sides of the filter housing 11, and a sealing cover 13 is located at the top of the filter housing 11;

[0040] The inside of the filter housing 11 is used to filter the gas, the connecting pipe 12 is used to be connected to the gas pipeline, and the sealing cover 13 is used to seal the upper end of the filter housing 11;

[0041] The fixing holes 27 are opened at both sides of the upper end of the filter housing 11, and the fixing holes 27 are opened relative to the fixing block 24;

[0042] By moving the lower end of the fixing block 24 to the inside of the fixing hole 27, the fixing block 24 is fixed inside the fixing hole 27, so that the sealing cover 13 is fixed by the support rod 22 and the support block 21;

[0043] The fixing block 24 is an L-shaped structure, and the bottom end of the telescopic spring 26 is fixedly connected to the upper end position inside the filter housing 11;

[0044] When the sealing cover 13 moves toward the inside of the filter housing 11, the sealing gasket 25 is driven to move inward, and the telescopic spring 26 is driven to be compressed;

[0045] Corresponding thread structures are provided on the outer surface of the support rod 22 and the inner surface of the movable rod 23, and a through hole is provided inside the support block 21 relative to the support rod 22;

[0046] By rotating the movable rod 23, the support rod 22 threadedly connected to the movable rod 23 is moved;

[0047] Working principle: When the sealing cover 13 needs to be installed, the sealing cover 13 is placed in the upper end position inside the filter housing 11, and the sealing cover 13 drives the sealing gasket 25 to move downward, and drives the telescopic spring 26 to compress. At this time, the fixing block 24 and the fixing hole 27 are flush, and the movable rod 23 is rotated to make the support rod 22 move inward through the threaded structure under the drive of the movable rod 23, and the support rod 22 drives the fixing block 24 to move inward, so that the fixing block 24 enters the fixing hole 27, and the sealing cover 13 can be fixed;

[0048] When the sealing cover 13 needs to be removed, the movable rod 23 is rotated in the opposite direction so that the support rod 22 drives the fixing block 24 to move outward. When the fixing block 24 is disengaged from the fixing hole 27, the elastic force generated by the compression of the telescopic spring 26 is generated. Under the action of the elastic force of the telescopic spring 26, the sealing gasket 25 and the sealing cover 13 move upward, and the sealing cover 13 can be removed. Example 2

[0049] See also Figure 4 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0050] The protection component 3 is fixedly connected to the outer side of the connecting pipe 12;

[0051] The protection assembly 3 includes a fixing column 31 fixedly connected to both sides of the connecting pipe 12, a fixing plate 32 fixedly connected to the outer end of the fixing column 31, a fixing shaft 33 fixedly connected to the inner sides of both ends of the fixing plate 32, a protection plate 34 rotatably connected to the outer surface of the fixing shaft 33, and a magnet 35 fixedly connected to the inner position of the outer end of the protection plate 34;

[0052] The fixing column 31 is used to fix the fixing plate 32 at both sides of the connecting pipe 12, the fixing plate 32 is used to fix the fixing shaft 33 at both ends of the connecting pipe 12, the fixing shaft 33 is used to support the protection plate 34, and the protection plate 34 can rotate along the fixing shaft 33, the protection plate 34 is used to protect the connecting pipe 12, and the magnets 35 are mutually attracted to fix the two sets of protection plates 34;

[0053] The inner side surface of the fixing plate 32 is in contact with the outer side surface of the connecting pipe 12, and the outer end surface of the protective plate 34 is located in the middle of the connecting pipe 12;

[0054] By changing the position of the protective plate 34, the protective plate 34 can provide different protections to the connecting pipe 12;

[0055] Working principle: When the outer end of the connecting tube 12 needs to be protected, the protective plate 34 is rotated downward to rotate along the fixed axis 33. When the protective plate 34 is rotated until the inner side surface is in contact with the outer side surface of the connecting tube 12, the two sets of protective plates 34 are fixed to the outer end surface of the connecting tube 12 under the mutual adsorption of the magnets 35, and impurities such as dust are blocked outside the connecting tube 12.

[0056] When the connecting pipe 12 is connected to the gas pipeline, the protective plate 34 needs to be rotated upward to expose the outer end of the connecting pipe 12. When the protective plate 34 is rotated to the upper end of the connecting pipe 12, rainwater on the upper side of the outer side of the connecting pipe 12 can be blocked, thereby preventing the outer end surface threads and bolts of the connecting pipe 12 from being difficult to disassemble due to rusting due to water.
