Description

Technical Field

[0001] This utility model belongs to the field of activated carbon technology, and in particular relates to an activated carbon canister with a high-efficiency sealing structure. Background Technology

[0002] Activated carbon is a material with a rich microporous structure. These micropores provide a large specific surface area for adsorbing and capturing gaseous pollutants (such as benzene, formaldehyde, and sulfur dioxide) from the air or liquid. Activated carbon canisters are filled with a large number of highly efficient activated carbon particles. When the gas to be purified flows through the canister, the pollutants undergo physical adsorption (or chemical adsorption) reactions with the activated carbon surface, thus achieving purification. Activated carbon canisters can be used for factory waste gas treatment, adsorbing and purifying harmful gases emitted during production before release, thereby meeting environmental protection requirements. However, due to unreasonable sealing structure design of the canisters in related technologies, long-term use or frequent disassembly can easily lead to seal failure, resulting in gas leakage or leakage of harmful substances, affecting the normal operation of the equipment and its environmental protection effectiveness. Summary of the Invention

[0003] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] An activated carbon canister with a high-efficiency sealing structure includes an upper canister, a lower canister, a first sealing structure, a second sealing structure, and a support structure.

[0006] The upper tank is provided with an air inlet pipe at the top, the lower tank is provided with an air outlet pipe on the side, and the lower tank is provided with the support structure at the bottom.

[0007] The bottom of the upper tank is detachably connected to the upper end of the lower tank through the first sealing structure. The second sealing structure is provided at the outer edge of the first sealing structure. The second sealing structure is used to seal the gap between the upper tank and the lower tank.

[0008] The first sealing structure includes a sealing end cap, a connecting sleeve, a first annular sealing gasket, and a first pressing assembly. The sealing end cap is disposed on the outer wall of the bottom of the upper tank body, and the connecting sleeve is disposed on the outer wall of the upper part of the lower tank body. The upper end face of the connecting sleeve is provided with a first annular groove, and the first annular sealing gasket is disposed in the first annular groove. The first pressing assembly is disposed on the sealing end cap and is used to press the first annular sealing gasket. The outer wall of the connecting sleeve is threadedly engaged with the inner wall of the sealing end cap.

[0009] Furthermore, the second sealing structure includes a fixing plate, a mounting base, a second pressing assembly, and a second annular sealing gasket. Both the mounting base and the fixing plate are annular structures. The mounting base is sleeved on the top of the outer wall of the lower tank body and is integrally connected to the lower tank body. The outer wall of the mounting base is provided with a second annular groove, and the second annular sealing gasket is disposed in the second annular groove. The fixing plate is located at the outer edge of the sealing cover and is integrally connected to the sealing cover. The second pressing assembly is disposed on the fixing plate and is used to press the second annular sealing gasket.

[0010] Furthermore, the first clamping assembly includes a plurality of clamping bolts, which are evenly arranged on the sealing cover. The first clamping assembly and the second clamping assembly have the same structure. The clamping bolts of the first clamping assembly are arranged vertically, while the clamping bolts of the second clamping assembly are arranged horizontally.

[0011] Furthermore, the mounting base is provided with multiple first reinforcing ribs at the connection point between it and the lower tank.

[0012] Furthermore, the support structure includes multiple support plates, which are evenly arranged circumferentially at the bottom of the lower tank. Each support plate is provided with a second reinforcing rib at the connection point between it and the lower tank.

[0013] Furthermore, the number of support plates is three.

[0014] Furthermore, both the first annular sealing gasket and the second annular sealing gasket are polytetrafluoroethylene gaskets, rubber gaskets, or polyurethane gaskets.

[0015] Compared with existing technologies, the activated carbon container with a high-efficiency sealing structure described in this utility model has the following advantages:

[0016] 1. The first sealing structure employs a combination of a sealing end cap, a connecting sleeve, a first annular sealing gasket, and a first clamping assembly, ensuring a tight connection between the upper and lower tanks and reducing the possibility of leakage. In particular, the first annular sealing gasket, located within the first annular groove on the connecting sleeve, effectively prevents gas or liquid leakage. The threaded fit design of the first sealing structure allows for the disassembly and reconnection of the upper and lower tanks. This provides a simple and effective disassembly method, facilitating equipment maintenance, cleaning, or parts replacement.

[0017] 2. The first clamping assembly consists of multiple clamping bolts, which, by being evenly distributed on the sealing gland, allow for precise adjustment of the clamping force on the sealing gasket, thereby achieving a better sealing effect. This results in a more uniform pressure distribution in the sealing structure, ensuring the durability and stability of the sealing gasket.

[0018] 3. The second sealing structure, through the design of the fixing plate, mounting base, second annular sealing gasket, and second clamping assembly, provides an additional sealing layer. The gap between the upper and lower tank bodies further enhances the sealing performance, effectively preventing gas or liquid leakage and ensuring the integrity of the sealing system. The second clamping assembly ensures uniform and sustained compression of the second annular sealing gasket, preventing localized leakage caused by uneven pressure. Through the clamping action of the second clamping assembly, the sealing gasket maintains a good sealing condition throughout the entire sealing process. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] An activated carbon container with a highly efficient sealing structure, such as Figure 1 As shown, it includes an upper tank 101, a lower tank 102, a first sealing structure, a second sealing structure, and a support structure; the top of the upper tank 101 is provided with an air inlet pipe 202, the side of the lower tank 102 is provided with an air outlet pipe 201, and the bottom of the lower tank 102 is provided with a support structure; the bottom of the upper tank 101 is detachably connected to the upper end of the lower tank 102 through the first sealing structure, and the outer edge of the first sealing structure is provided with a second sealing structure, which is used to seal the gap between the upper tank 101 and the lower tank 102;

[0031] like Figure 2-3As shown, the first sealing structure includes a sealing end cap 302, a connecting sleeve 501, a first annular sealing gasket 502, and a first pressing assembly 304. The sealing end cap 302 is disposed on the outer wall of the bottom of the upper tank 101, and the connecting sleeve 501 is disposed on the outer wall of the upper part of the lower tank 102. The upper end face of the connecting sleeve 501 has a first annular groove, and the first annular sealing gasket 502 is disposed in the first annular groove. The first pressing assembly 304 is disposed on the sealing end cap 302 and is used to press the first annular sealing gasket 502. The outer wall of the connecting sleeve 501 is threadedly engaged with the inner wall of the sealing end cap 302. The first sealing structure, using the combination of the sealing end cap 302, the connecting sleeve 501, the first annular sealing gasket 502, and the first pressing assembly 304, ensures a tight connection between the upper tank 101 and the lower tank 102, reducing the possibility of leakage. In particular, the first annular sealing gasket 502, located in the first annular groove on the connecting sleeve 501, can effectively prevent the leakage of gas or liquid. The first sealing structure, through a threaded fit design, allows the upper tank 101 and the lower tank 102 to be disassembled and reconnected. This provides a simple and effective disassembly method, facilitating equipment maintenance, cleaning, or parts replacement.

[0032] like Figure 2-3 As shown, the second sealing structure includes a fixing plate 301, a mounting base 401, a second pressing assembly 303, and a second annular sealing gasket 402. Both the mounting base 401 and the fixing plate 301 are annular structures. The mounting base 401 is fitted onto the top of the outer wall of the lower tank 102 and is integrally connected to the lower tank 102. The outer wall of the mounting base 401 has a second annular groove, and the second annular sealing gasket 402 is disposed within the second annular groove. The fixing plate 301 is positioned at the outer edge of the sealing cap and is integrally connected to the sealing cap. The second pressing assembly 303 is disposed on the fixing plate 301 and is used to press the second annular sealing gasket 402. Multiple first reinforcing ribs 403 are provided at the connection point between the mounting base 401 and the lower tank 102. Both the first annular sealing gasket 402 and the second annular sealing gasket 402 are rubber gaskets. The second sealing structure, through the design of the fixing plate 301, mounting base 401, second annular sealing gasket 402, and second clamping assembly 303, provides an additional sealing layer. The gap between the upper tank 101 and the lower tank 102 further enhances the sealing performance, effectively preventing gas or liquid leakage and ensuring the integrity of the sealing system. The second clamping assembly 303 ensures uniform and sustained compression of the second annular sealing gasket 402, preventing localized leakage caused by uneven pressure. Through the clamping action of the second clamping assembly 303, the sealing gasket maintains a good sealing condition throughout the sealing process.

[0033] The first clamping assembly 304 includes multiple clamping bolts evenly distributed on the sealing gland. The first clamping assembly 304 has the same structure as the second clamping assembly 303, but the clamping bolts of the first clamping assembly 304 are vertically arranged, while those of the second clamping assembly 303 are horizontally arranged. The first clamping assembly 304, composed of multiple clamping bolts evenly distributed on the sealing gland, allows for precise adjustment of the clamping force on the sealing gasket, thereby achieving a better sealing effect. This results in a more uniform pressure distribution in the sealing structure, ensuring the durability and stability of the sealing gasket.

[0034] The support structure includes multiple support plates 601, which are evenly arranged circumferentially at the bottom of the lower tank 102. Each support plate 601 is provided with a second reinforcing rib 602 at the connection point with the lower tank 102. There are three support plates 601.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
