Description

Technical Field

[0002] Activated carbon is a black porous solid carbon, which is produced by coal crushing, molding or carbonization and activation with uniform coal particles. The main component is carbon, and contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine and other elements. The core component of the activated carbon filter box is the activated carbon filter material, which is a carbon material with high adsorption performance. The surface area of ​​the activated carbon filter material is huge, and it has a rich microporous structure inside. These micropores can absorb harmful gases and odor molecules in the air. When the air passes through the activated carbon filter box, the harmful substances are adsorbed on the surface of the filter material, thereby purifying the air. The working principle of the activated carbon filter box mainly includes three stages: adsorption, diffusion and desorption.

[0034] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0035] like Figures 1 to 5 As shown, a multi-stage activated carbon filter box includes a box body 1, an air inlet 2 is arranged on one side of the box body 1 with a cavity on the inner side, so that the gas to be filtered can enter the inner side of the box body 1, a placement rack 3 slidably connected to the inner side of the box body 1 is provided with a cover plate 301, a fixing rack 302 is arranged on the surface of the cover plate 301, and an activated carbon plate 4 is conveniently slidably connected to the inner side thereof through a placement groove 303 at the bottom end of the fixing rack 302 and a limiting strip 304 at the top end, a limiting assembly 5 located at the connection between the placement rack 3 and the activated carbon plate 4 is provided with an installation groove 501, and a moving rod 502 controlled by a handpiece 506 on the inner side of the installation groove 501 enables the limiting member 504 fixed with the baffle 503 to be clamped on the surface of the activated carbon plate 4 to limit it, and an air outlet 6 located on the other side surface of the box body 1 allows the filtered air to be discharged under the monitoring of a gas detector 7 arranged on the surface.

[0036] The sealing ring 101 disposed on the surface of the box body 1 fits with the sealing ring 306 on the inner side of the cover plate 301 , and a buckle assembly 305 is disposed at one end of the surface of the cover plate 301 .

[0037] Through the above technical solution, with the cooperation of the two sealing rings and the buckle assembly 305, the sealing effect of the connection between the cover plate 301 and the box body 1 is better, thereby preventing gas leakage inside the box body 1.

[0038] The snap assembly 305 is provided with a fixing part 351 fixed on the surface of the cover plate 301, which is connected with a clamping part 352 clamped on the inner side thereof, a fixing shaft 353 is provided on the inner side of the clamping part 352 to facilitate its rotation, and a sliding pressing part 354 is provided above the clamping part 352 to control the clamping part 352 to clamp the fixing part 351 under the elastic force of a spring 355.

[0039] Through the above technical solution, under the limitation of the fixed shaft 353, the clamping member 352 can be clamped on the inner side of the fixing member 351 through the elastic force of the spring 1 355, thereby limiting the position of the cover plate 301, thereby improving the firmness of the seal between the cover plate 301 and the box body 1.

[0040] A spring 2 356 is disposed on one side of the spring 1 355 and is connected to a push block 357 , and the push block 357 is attached to the bottom surface of the fixing member 351 .

[0041] Through the above technical solution, under the pressure of the second spring 356, after the clamping member 352 is separated from the fixing member 351, the pushing block 357 can push the fixing member 351 to be separated by the pressure of the second spring 356, making it easier to pull out the cover 301.

[0042] The position of the limiting member 504 clamped on the inner side of the activated carbon plate 4 is controlled by the moving rod 502.

During the discharge process, the gas content is always detected by the gas detector 7. When it is higher than the set value, the signal is transmitted to the terminal to remind the operator to replace the activated carbon plate 4. In the process of replacing the activated carbon plate 4, first press the pressing member 354 so that the clamping member 352 can squeeze the spring 1 355 through the fixed shaft 353, so that one end of it is separated from the fixing member 351, so that under the elastic force of the spring 2 356, the fixing member 351 is separated, so that the placement rack 3 can be pulled out conveniently, and then the handpiece 506 is pulled to squeeze the spring 3 505 to separate the limit member 504 from the activated carbon plate 4, so that the activated carbon plate 4 can be pulled out for replacement.

[0045] The gas detector 7 is an existing product on the market, and its connection mode and control method are both existing technologies and will not be described in detail here.
