[0002] The environmental protection treatment of waste gas in factories has always been the focus of the industrial processing field. It is mainly to ensure that the waste gas is effectively filtered and treated during discharge to meet the environmental emission requirements. Generally, various filter core materials are used to purify the waste gas. For example, the existing patent with publication number CN213760967U discloses "a waste gas treatment and transportation device for environmental protection equipment, including a vacuum pump fixedly provided at the bottom end of the outer wall of the gas storage tank, an air guide pipe fixedly provided on the other side of the vacuum pump, and one end of the air guide pipe is connected to one side of the vacuum pump, and a filter box is fixedly provided at the other end of the air guide pipe, a filter screen is inserted through one side of the filter box, a push block is fixedly provided on one side of the filter screen, and a push handle is fixedly provided on the upper and lower ends of one side of the push block, and a box cover is clamped at the bottom of the filter box".

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figures 1 to 4 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: an environmental waste gas treatment device, comprising

[0023] A filter box 1, an air inlet pipe 11 and an air outlet pipe 12 respectively arranged on both side surfaces of the filter box 1, a plurality of strip-shaped sockets 13 opened on the front surface of the filter box 1, and a filter assembly 2 installed at the strip-shaped sockets 13;

[0024] The filter assembly 2 includes an outer cover plate 23, a filter frame 21 welded and fixed to the rear surface of the outer cover plate 23, and an activated carbon filter core material 22 installed on the inner side of the filter frame 21. The activated carbon filter core material 22 is composed of activated carbon and PP cotton, is breathable, and can absorb harmful substances in the exhaust gas through the activated carbon during the ventilation process. The filter frame 21 is inserted into the inner side of the filter box 1 through the strip socket 13. The exhaust gas that needs to be purified subsequently enters the filter box 1 through the air inlet pipe 11 and contacts with the activated carbon filter core material 22. The activated carbon filter core material 22 purifies and absorbs the exhaust gas, and the treated gas is discharged through the exhaust pipe 12.

[0025] The front surface of the filter box 1 is provided with a rotating disassembly structure 3 relative to the top and bottom of each filter assembly 2. The rotating disassembly structure 3 includes a cylindrical inner groove 33 opened in the filter box 1, a spring 34 and a cylindrical inner block 35 installed in the cylindrical inner groove 33, and a cylindrical base block 31 fixed to the front surface of the cylindrical inner block 35. The front end of the cylindrical base block 31 penetrates the front surface of the filter box 1 and is fixed with a limiting pressure block 32, and one end of the limiting pressure block 32 is pressed on the front surface of the outer cover plate 23, which can stably press and limit the outer cover plate 23 to ensure the installation stability of the filter assembly 2. Subsequently, it is only necessary to pull the limiting pressure block 32 forward and rotate it away from the front surface of the outer cover plate 23, and the outer cover plate 23 can be directly pulled forward to realize the rapid extraction of the filter frame 21 and the activated carbon filter core material 22. The rotating disassembly structure 3 also includes a spring 34 and a cylindrical inner block 35 installed in the cylindrical inner groove 33, and a cylindrical base block 31 fixed to the front surface of the cylindrical inner block 35. The front end of the cylindrical base block 31 passes through the front surface of the filter box 1 and is fixed with a limiting pressure block 32, and one end of the limiting pressure block 32 is pressed on the front surface of the outer cover plate 23, so that the outer cover plate 23 can be stably pressed and limited to ensure the installation stability of the filter assembly 2. The blocks 36 at both ends of the outer cover 23 are provided with slots 37 corresponding to the blocks 36. The blocks 36 are embedded in the slots 37, so that the ends of the limiting pressure blocks 32 can be stably pressed on the surface of the outer cover 23, thereby ensuring the stability of the compression and limiting of the filter assembly 2. If the activated carbon filter core material 22 is to be removed from the filter box 1 for maintenance and replacement in the future, it is only necessary to first pull the limiting pressure block 32 forward with force, so that the cylindrical base block 31 moves forward with the cylindrical inner block 35, and compress the spring 34, so that the block 36 moves out of the slot 37. At this time, the end of the limiting pressure block 32 can be rotated and removed from the front of the outer cover 23, and no obstruction will be caused to the outer cover 23. At this time, the outer cover 23 can be pulled forward, and the filter frame 21 and the activated carbon filter core material 22 can be smoothly pulled out from the filter box 1, which is convenient for maintenance and replacement of the activated carbon filter core material 22.

[0026] One end of the spring 34 abuts against the inner wall of the cylindrical inner groove 33 , and the other end of the spring 34 is in tight contact with the cylindrical inner block 35 .

[0027] The front end of the cylindrical inner groove 33 is penetrated by a circular rod hole corresponding to the front surface of the filter box 1, and the circular rod hole corresponds to the cylindrical base block 31, so as to facilitate the smooth penetration and subsequent rotation of the cylindrical base block 31.

[0028] Among them, four supporting legs are arranged at the bottom of the filter box 1.

[0029] Example 2

[0030] See also Figures 1 to 5 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the sealing performance of the filter assembly 2 after installation can be ensured by setting a sealing structure.

[0031] Specifically, it also includes a sealing structure, which is arranged between the filter frame 21 and the strip socket 13. The sealing structure includes a U-shaped rubber ring 25 mounted on the surface of the filter frame 21, a U-shaped protrusion 24 arranged on the surface of the U-shaped rubber ring 25, and a U-shaped groove 14 opened on the inner wall of the strip socket 13. The U-shaped protrusion 24 is embedded in the U-shaped groove 14, which can ensure the sealing of the filter component 2 after installation and prevent exhaust gas from leaking from the strip socket 13.

[0032] Among them, the U-shaped protrusion 24 and the U-shaped rubber ring 25 are an integrated structure, both of which are made of rubber material and will undergo elastic deformation when squeezed. A U-shaped cavity with an elliptical cross-section is provided in the U-shaped rubber ring 25, so that the U-shaped protrusion 24 has sufficient deformation space when squeezed.

[0033] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
