Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon filtering, in particular to an activated carbon filtering device which is convenient to replace. Background Art

[0002] As we all know, activated carbon filtration is the process of water treatment using activated carbon as filter material; activated carbon is a black solid substance with carbon as its skeleton structure and developed pores through gasification; its developed pores give it a large specific surface area, thus having good adsorption properties.

[0003] After the existing activated carbon filter device has been filtering medical laboratory waste gas for a long time, a large amount of adsorbed impurities will adhere to the mesh of the activated carbon filter. Due to the lack of a structural setting that facilitates the rapid disassembly and assembly of the activated carbon filter on the filter device, it is inconvenient to replace the activated carbon filter. Therefore, we propose an activated carbon filter device that is easy to replace.

[0004] The above information disclosed in the Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may include information that does not constitute the prior art that is already known to one of ordinary skill in the art.

[0009] By adopting the above technical scheme, after the negative pressure fan inside the second shell is started, the exhaust gas can enter the first shell, and the exhaust gas can be discharged through the second shell after being adsorbed by the activated carbon filter. In addition, when the activated carbon filter needs to be replaced, the rod body can be driven to rotate clockwise by rotating the first screw rod or the second screw rod, so that the two movable plates can move away from each other under the action of the first screw rod and the second screw rod, and then the plug can be moved out of the slot under the action of the movable plate, so that the frame and the activated carbon filter can be taken out from the adjacent gaps of the first shell and the second shell; when the activated carbon filter needs to be installed, the frame and the activated carbon filter can be placed between the first shell and the second shell first, and then the rod body can be rotated counterclockwise under the resetting action of the torsion spring by loosening the first screw rod or the second screw rod, so that the two movable plates can drive the plug to be inserted into the slot under the action of the first screw rod and the second screw rod to position the frame and the activated carbon filter.

[0010] Preferably, one end of the limiting rod away from the second shell is fixedly connected with a protrusion.

[0012] Preferably, adjacent sides of the first shell and the second shell are both fixedly connected with a rubber pad, and one side of the rubber pad is tightly attached to the frame.

[0013] By adopting the above technical solution, the elastic force of the rubber pad can make the two sides of the frame body pressed tightly, thereby preventing the gas from flowing out from the gap formed by the frame body and the first shell and the second shell during the circulation process.

[0014] Preferably, one end of the second screw rod away from the rod body is fixedly connected with a handle.

[0015] By adopting the above technical solution, the second screw rod can be easily rotated.
