[0003] In the prior art, when filtering and treating harmful gases, related filtering equipment is usually used to absorb or treat the harmful gases. The current filtering equipment is usually equipped with multiple activated carbon plates inside. When the harmful gases pass through the activated carbon plates, because the activated carbon plates have super adsorption capacity, they can adsorb the harmful gases on the surface. After long-term use, the activated carbon plates need to be removed for cleaning or maintenance. Due to the limited space inside the device, when installing and removing the activated carbon plates, the staff can only remove the activated carbon plates in this way.

The bottom of the second clamping plate 11 is fixed to the upper surface of the first wedge block. An activated carbon plate 7 is fixed between the first clamping plate 10 and the second clamping plate 11. Through grooves corresponding to the first wedge block are respectively opened on both sides of the bottom of the activated carbon plate 7.

[0033] Among them, the fixing mechanism also includes two groups of fixing columns 13, one ends of the two groups of fixing columns 13 are respectively fixed to the inner wall of the main body 1, and the outer sides of the two groups of fixing columns 13 are sleeved with second springs 14, and one end of the two fixing columns 13 on the same side is slidably installed with a second wedge block 15, and one end of the two second springs 14 on the same side is fixed to the corresponding second wedge block 15, and the interior of the two second wedge blocks 15 is provided with a second sliding groove 16, and one end of each group of fixing columns 13 is slidably installed in the interior of the second wedge block 15 through the second sliding groove 16, and a connecting plate 17 is installed above the two second wedge blocks 15. By sliding the two sliders 9 to the first sliding groove and sliding to a certain position, the quick installation work can be completed by the cooperation of the wedge surfaces of the first wedge block and the second wedge block 15. Conversely, the quick disassembly work can be completed by pressing the pressing handle 3 and cooperating with the two connecting plates 17, thereby improving the work efficiency.

[0034] The bottom of the connecting rod 4 is provided with a wedge-shaped surface, and one side of the two second wedge-shaped blocks 15 is provided with a corresponding wedge-shaped surface.

[0035] Among them, one end of the two first wedge blocks is set against one side of the fixed plate 19, the fixing mechanism and the lower half of the connecting rod 4 are both inside the isolation plate 18, and the multiple third springs 21 arranged on the back side of the fixed plate 19 can give opposite elastic forces to the two first wedge blocks, which is beneficial for the staff to disassemble the activated carbon plate 7.

[0036] A groove 6 is provided on the top of the main body 1, a first spring 5 is sleeved on the outer side of the connecting rod 4, and the rod wall of the connecting rod 4 passes through the groove 6.

[0038] The working principle of this embodiment is as follows: first, the device is transported to the designated workplace, and then the harmful gas enters the interior of the device for filtering. When the activated carbon plate 7 needs to be disassembled, the staff presses the pressing handle 3 by hand to drive the bottom wedge surface to contact the two connecting plates 17, thereby squeezing the connecting plates 17. The connecting plates 17 are subjected to force to drive the two second wedge blocks 15 to run respectively. The operation of the two second wedge blocks 15 can drive the second spring 14 to run synchronously, so that the second wedge block 15 can be separated from the first wedge block. At this time, the fixed plate 19 loses pressure restriction, and the multiple third springs 21 give the fixed plate 19 a reverse elastic force, so that the staff can easily take out the activated carbon plate 7 together, thereby completing the disassembly work;

[0039] When the activated carbon board 7 needs to be installed again after repair, the slider 9 is aligned with the first slide groove and slid into the device. When it reaches a certain position, the wedge surface of the first wedge block cooperates with the wedge surface of the second wedge block 15, so that the first wedge block and the second wedge block 15 can be smoothly engaged again, thereby completing the work of installing multiple activated carbon boards 7 at one time, thereby improving work efficiency.
