Abstract
Description
Technical Field
[0001] This utility model relates to the field of activated carbon adsorption box technology, and in particular to an activated carbon adsorption box. Background Technology
[0002] Activated carbon adsorption boxes are widely used in industrial environmental management and air purification. They utilize activated carbon as an adsorbent, effectively removing harmful substances from the air, such as volatile organic compounds (VOCs), odors, smoke, particulate matter, and other pollutants, through physical and chemical adsorption processes.
[0003] Activated carbon possesses a highly developed pore structure and a large specific surface area, giving it an extremely strong adsorption capacity. An activated carbon adsorption box typically consists of a box body, a layer of activated carbon, a fan, and necessary piping. Air is introduced into the adsorption box through the inlet by the fan. As it passes through the activated carbon layer, pollutants are captured by the activated carbon, and the purified air is discharged from the outlet.
[0004] After prolonged adsorption in the activated carbon adsorption box, the adsorption effect of the activated carbon in the activated carbon drawer will significantly decrease. Catalysis with high-temperature air can detach the particles from the activated carbon for reuse. However, after many uses, the activated carbon will no longer be able to perform effective adsorption. At this point, the activated carbon in the activated carbon drawer needs to be removed and replaced. In the existing technology, the activated carbon drawer is connected to the box body with bolts. However, the activated carbon adsorption box itself is a sealed container. After repeated disassembly and installation, the sealing between the activated carbon drawer and the box body will decrease due to loosening and wear of the bolt connections.
[0005] Therefore, an activated carbon adsorption box is proposed to solve or alleviate the above problems. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an activated carbon adsorption box.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] An activated carbon adsorption box includes a box body and several activated carbon drawers. Several coaxially arranged through grooves are opened on opposite side walls of the box body. The activated carbon drawers are slidably connected in the through grooves. Thermal expansion components are fixedly connected to two of the coaxially arranged activated carbon drawers. A sliding cover with a closed sliding groove is slidably connected to the side wall of the box body. An adhesive layer is fixedly connected to the side of the activated carbon drawer away from the thermal expansion component.
[0009] Preferably, the end of the activated carbon drawer away from the thermal expansion component is fixedly connected to a sheet-like connecting frame located on its outer ring. The adhesive layer is fixedly connected to the end face of the connecting frame flush with the box body. There is a gap between the connecting frame and the side wall of the box body. A thermal expansion ring sleeved on the outside of the activated carbon drawer is fixedly connected to the side of the connecting frame away from the adhesive layer. The normal thickness of the thermal expansion ring is less than the width of the gap.
[0010] Preferably, the sliding cover is fixedly connected to a U-shaped back frame on the side facing the box body. The back frame is slidably connected to the side wall of the box body. The cross-section of the back frame is L-shaped, and there is a groove between the back frame and the sliding cover for embedding the connecting frame, the adhesive layer, and the thermal expansion ring.
[0011] Preferably, the thermal expansion component includes a protrusion and a concave part, and the protrusion and concave part of two activated carbon drawers located on the same axis are arranged opposite to each other, and a thermal expansion ball is provided in the concave part.
[0012] Preferably, the recess includes a cylindrical connecting recess, the thermal expansion ball is fixedly connected to the inner bottom surface of the connecting recess, and the protrusion includes a connecting seat fixedly connected to the activated carbon drawer and a plug fixedly connected to the connecting seat, the plug being used to insert into the connecting recess.
[0013] Preferably, the thermal expansion ball protrudes outward from the side facing the opening of the connecting recess to form a protrusion.
[0014] Preferably, the thermal expansion ball and thermal expansion ring are made of neoprene rubber.
[0015] This utility model has the following beneficial effects:
[0016] In this design, when the activated carbon in the activated carbon adsorption box reaches its replacement cycle, the operator simply places new activated carbon into the activated carbon drawer and slides the drawer into the through slot. Adjacent activated carbon drawers are positioned and connected by a thermal expansion component. After the activated carbon adsorption box is started, the thermal expansion component will expand in response to the temperature change during operation. This will naturally adjust the distance between the drawers and promote the expansion behavior of the thermal expansion ring inside the sliding cover, further enhancing the contact sealing between the drawer and the through slot. This design allows the activated carbon adsorption box to achieve excellent sealing effect without using traditional bolts or threaded fixing methods, while also facilitating quick replacement of activated carbon during maintenance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] An activated carbon adsorption box, such as Figure 1 and 2 As shown, the box includes a housing 1 and several activated carbon drawers 3. Several coaxially arranged through grooves are provided on the opposite side walls of the housing 1. The activated carbon drawers 3 are slidably connected in the through grooves. Thermal expansion components are fixedly connected to two coaxially arranged activated carbon drawers 3. A sliding cover 2 with a closed slide groove 202 is slidably connected to the side wall of the housing 1.
[0026] like Figure 3 As shown, a U-shaped back frame 201 is fixedly connected to the side of the sliding cover 2 facing the box 1. The back frame 201 is slidably connected to the side wall of the box 1. The cross-section of the back frame 201 is L-shaped, and there is a groove 202 between the back frame 201 and the sliding cover 2 for the connecting frame 301, the adhesive layer 303 and the thermal expansion ring 302 to be embedded.
[0027] like Figure 4As shown, the activated carbon drawer 3 is fixedly connected to a sheet-like connecting frame 301 located on its outer ring at one end away from the thermal expansion component. An adhesive layer 303 is fixedly connected to the side of the activated carbon drawer 3 away from the thermal expansion component. The adhesive layer 303 is fixedly connected to the end face of the connecting frame 301 that is flush with the box body 1. There is a gap between the connecting frame 301 and the side wall of the box body 1. A thermal expansion ring 302 made of neoprene rubber is fixedly connected to the side of the connecting frame 301 away from the adhesive layer 303 and is sleeved on the outside of the activated carbon drawer 3. The normal thickness of the thermal expansion ring 302 is less than the width of the gap. The thermal expansion ring 302 is U-shaped and its cross-section is rectangular.
[0028] And such Figure 5 As shown, the thermal expansion assembly includes a protrusion and a concave part. The protrusions and concave parts of two activated carbon drawers 3 located on the same axis are arranged opposite each other. A thermal expansion ball 306 made of neoprene rubber is provided inside the concave part. The thermal expansion ball 306 protrudes outward from the side facing the opening of the connecting concave seat 305 to form a protrusion 3061. The concave part includes a cylindrical connecting concave seat 305. A ring-shaped gasket is fixedly connected to the closed end of the connecting concave seat 305. The connecting concave seat 305 is fixedly connected to the activated carbon drawer 3 by bolts. Figure 6 As shown, the thermal expansion ball 306 is fixedly connected to the inner bottom surface of the connecting recess 305. The thermal expansion ball 306 is flattened spherical and is glued to the connecting recess 305 with adhesive. The outer diameter of the thermal expansion ball 306 is larger than the inner diameter of the connecting recess 305. The protrusion includes a connecting seat 304 fixedly connected to the activated carbon drawer 3 and an insert 3041 fixedly connected to the connecting seat 304. The insert 3041 is used to insert into the connecting recess 305. The connecting seat 304 is also columnar. One end of the connecting seat 304 is fixedly connected to an annular gasket flush with its end face. The annular gasket is fixedly connected to the activated carbon drawer 3 with bolts.
[0029] When the activated carbon in this activated carbon adsorption box is used up to the point where the adsorption effect is extremely poor and needs to be replaced, the operator only needs to stop the flow of waste gas into the activated carbon adsorption box and wait for a period of time until the temperature of the activated carbon adsorption box drops to room temperature before proceeding with subsequent operations.
[0030] After removing the activated carbon drawer 3, the waste activated carbon inside is removed. After cleaning and drying, new activated carbon is filled into the activated carbon drawer 3. Then, the activated carbon drawer 3 is manually inserted into the through groove so that the thermal expansion components on the two activated carbon drawers 3 on the same axis can be interlocked. The protrusion on one activated carbon drawer 3 is inserted into the concave part of the other activated carbon drawer 3, and vice versa. Specifically, the insert 3041 extends into the connecting recess 305 and is fitted with the end face of the protrusion 3061 of the thermal expansion ball 306 and the insert 3041.
[0031] At this point, the activated carbon drawers 3 on both sides have reached their maximum displacement state. At this point, there is a gap between the thermal expansion ring 302 on the connecting frame 301 on one side of the activated carbon drawer 3 and the side wall of the box 1. The operator can then manually move the sliding cover 2 downwards so that the adhesive layer 303, the connecting frame 301, and the thermal expansion ring 302 can be smoothly embedded into the space between the sliding cover 2 and the back frame 201 through the sliding groove 202. At this point, the sliding cover 2 completely covers the opening of the through groove and the activated carbon drawer 3.
[0032] Subsequently, the activated carbon adsorption box begins to work with high-temperature exhaust gas. At this time, the temperature inside the box 1 rises, and the thermal expansion ball 306 also undergoes thermal expansion deformation. Since a protrusion 3061 is provided on it, the protrusion 3061 also abuts against the insertion post 3041. In this way, when the thermal expansion ball 306 deforms and expands, it will push the insertion post 3041 out first, which makes the activated carbon drawers 3 on both sides move away from each other, so that the activated carbon drawers 3 can abut against the sliding cover 2 through the sealant layer 303.
[0033] Furthermore, as heat is transferred, the thermal expansion ring 302 will also undergo elastic deformation. After expanding, it will abut against the connecting frame 301 and the back frame 201, thereby further sealing the gaps between the activated carbon drawer 3, the box body 1, and the sliding cover 2. This improves the overall sealing effect of the activated carbon adsorption box, and eliminates the need for bolts or threads, reducing the likelihood of wear. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
