Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, and in particular to an activated carbon adsorption device. Background Technology

[0002] In the environmental protection field, activated carbon adsorption devices are key equipment for purifying organic waste gas and eliminating odors, and are highly effective in removing odors from water, natural and synthetic dissolved organic matter, and micropollutants. As the usage time increases, the activated carbon adsorption plates in the activated carbon adsorption device need to be replaced.

[0003] Currently, activated carbon adsorption devices suffer from the following shortcomings: Firstly, design flaws make replacing activated carbon adsorption plates extremely inconvenient. Replacement requires significant time and effort from the user, and the complex process not only increases labor intensity but also severely reduces the device's practicality. Secondly, uneven intake of waste gas during operation leads to uneven residue of dust particles, resulting in significant differences in adsorption capacity across different parts of the activated carbon filter. When some parts require plate replacement due to excessive adsorption, other parts remain usable. This wastes activated carbon adsorption plate resources, affects the device's adsorption efficiency and treatment effect, and reduces the device's overall effectiveness. Utility Model Content

[0004] In view of this, the present invention proposes an activated carbon adsorption device to improve the convenience of replacing activated carbon filter plates.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An activated carbon adsorption device includes a hollow rectangular parallelepiped tank. The tank has an air inlet on its front side and an air outlet on its rear side. A mounting base is located inside the tank. A first through-hole, directly opposite the mounting base, is opened on the top surface of the tank. An activated carbon filter plate, inserted into the mounting base, is located inside the tank. The top of the activated carbon filter plate is placed within the first through-hole and is sealed by a sealing plate on the outer top surface of the tank. A horizontal pushing clamping structure is provided on both sides of the first through-hole on the inner top surface of the tank. A second through-hole is opened on both sides of the first through-hole on the outer top surface of the tank. Each second through-hole can be equipped with a clamping control rod, which controls the horizontal pushing clamping structure to clamp / detach the activated carbon filter plate.

[0007] To better achieve the above technical solution, optionally, the second through hole is a threaded hole, the upper part of the clamping control rod has an external thread, the top of the clamping control rod is provided with a control handle, and the bottom of the clamping control rod is provided with a frustum push block.

[0008] Optionally, the clamping control rod has a limiting plate at the lower part of its rod thread, and the limiting plate is located below the second through hole.

[0009] Optionally, the flat-push clamping structure includes a mounting base, a triangular block, a translation push rod, and an elastic element. The mounting base is fixed to the inner top surface of the tank. The bottom right-angled surface of the triangular block is movably disposed within the mounting base. The translation push rod movably passes through the side plate of the mounting base near the activated carbon filter plate and is fixedly connected to the side right-angled surface of the triangular block. The elastic element is sleeved on the translation push rod and clamped between the side plate of the mounting base near the activated carbon filter plate and the side right-angled surface of the triangular block. The inclined surface of the triangular block abuts against the side wall of the frustum push block.

[0010] Optionally, the bottom surface of the mounting base is provided with a guide rail extending along the thickness direction of the activated carbon filter plate, and the bottom right-angled surface of the triangular block is slidably mounted on the guide rail.

[0011] Optionally, the end of the translation push rod near the activated carbon filter plate has a clamping head, and the activated carbon filter plate has clamping grooves on both sides that cooperate with the clamping head.

[0012] Optionally, the top surface of the sealing plate is provided with a handle.

[0013] Optionally, a guide plate is provided on the inner wall of the tank and on the side near the air inlet, and at least one guide vane is mounted on the guide plate;

[0014] Optionally, the guide plate is a fine mesh grille, and the guide vane is provided with a protective cover on the side near the air inlet.

[0015] Optionally, there is at least one activated carbon filter plate.

[0016] The beneficial effects of this utility model are:

At the same time, the activated carbon filter plate can be easily loaded and unloaded by simply raising and lowering the clamping control rod, which greatly saves time and manpower, effectively reduces downtime, improves operating efficiency, and reduces maintenance costs and labor intensity.

[0018] The guide vanes and fan blades allow the exhaust gas to enter the activated carbon filter plate evenly. The guide vanes distribute the air intake evenly, break up large particles, and prevent them from impacting the activated carbon filter plate. The rotating fan blades further disperse the airflow and improve the adsorption effect. Attached Figure Description

Detailed Implementation

[0023] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.

[0024] Please see Figures 1 to 3 This utility model discloses an activated carbon adsorption device, including a tank 10, an activated carbon filter plate 22, a card holder 21, and a flat-push clamping structure.

[0025] like Figure 1 As shown, the tank 10 has a hollow cuboid structure. The front and rear sides of the tank 10 are both narrowed structures. The front side of the tank 10 is provided with an air inlet 11, and the rear side of the tank 10 is provided with an air outlet 12.

[0026] The canister 10 is provided with a mounting base 21. The top surface of the canister 10 is provided with a first through hole 13 that is directly opposite the mounting base 21. The first through hole 13 extends along the length of the canister 10 to the left and right sides of the canister 10. The canister 10 is provided with an activated carbon filter plate 22 that is inserted into the mounting base 21. The top of the activated carbon filter plate 22 is placed in the first through hole 13 and is provided with a sealing plate 222 that is sealed on the top surface of the canister 10. Specifically, the mounting base 21 is a strip structure with a top slot. The mounting base 21 is fixed to the bottom wall of the canister 10 and the activated carbon filter plate 22 is inserted into the slot.

[0027] The inner top surface of the tank body 10 is provided with a flat-push clamping structure on both sides of the first through hole 13. The outer top surface of the tank body 10 is provided with a second through hole 14 on both sides of the first through hole 13. Each second through hole 14 can be equipped with a clamping control rod 31 that can be raised or lowered. By raising or lowering the clamping control rod 31, the flat-push clamping structure can be controlled to clamp / release the activated carbon filter plate 22.

[0028] The activated carbon adsorption device of this embodiment operates as follows when installing the activated carbon filter plate 22: The activated carbon filter plate 22 is inserted into the first through hole 13 and secured to the holder 21. Then, the two clamping control rods 31 are driven to descend. This action drives the two horizontal clamping structures to move relative to each other, thereby clamping the activated carbon filter plate 22 and working together with the holder 21 to fix the activated carbon filter plate 22. When the activated carbon filter plate 22 needs to be replaced, simply drive the two clamping control rods 31 to rise. At this time, the two horizontal clamping structures will move in opposite directions, thus disengaging from the activated carbon filter plate 22, allowing for easy removal of the activated carbon filter plate 22.

[0029] In this embodiment, the second through hole 14 is a threaded hole, and the upper middle part of the clamping control rod 31 has an external thread. A control handle 33 is provided at the top of the clamping control rod 31, and a frustum push block 32 is provided at its bottom. By rotating the control handle 33, the flat-push clamping structure can be driven to move. The threaded drive provides stable and precise control for operation. When the control handle 33 is rotated, the flat-push clamping structure can be pushed smoothly, so that the clamping force can be evenly applied to the activated carbon filter plate 22, effectively avoiding damage to the filter plate due to excessive local force.

[0030] Furthermore, the clamping control rod 31 is provided with a limiting plate 34 at the lower part of its threaded section, which is located below the second through hole 14. The limiting plate 34 effectively prevents the clamping control rod 31 from disengaging from the second through hole 14 due to excessive upward movement.

[0031] In this embodiment, the flat-push clamping structure includes a mounting base 231, a triangular block 232, a translation push rod 233, and an elastic element 235. The mounting base 231 is a rectangular frame structure with an open top. It is mounted on the inner top surface of the tank 10. The bottom right-angled surface of the triangular block 232 can move within the mounting base 231. Specifically, the bottom surface of the mounting base 231 is provided with a guide rail (not shown in the figure) extending along the thickness direction of the activated carbon filter plate 22. The bottom right-angled surface of the triangular block 232 can slide on this guide rail. The translation push rod 233 movably passes through the side plate of the mounting base 231 near the activated carbon filter plate 22 and is fixedly connected to the side right-angled surface of the triangular block 232. The elastic element 235 is sleeved on the translation push rod 233 and clamped between the side plate of the mounting base 231 near the activated carbon filter plate 22 and the side right-angled surface of the triangular block 232. The inclined surface of the triangular block 232 forms a contact mating fit with the side wall of the frustum pusher block 32. When the clamping control rod 31 pushes the triangular block 232 towards the activated carbon filter plate 22, the elastic element 235 is compressed, with the elastic element 235 preferentially compressing the spring. As the translation pusher 233 moves, it clamps against the side wall of the activated carbon filter plate 22. When the clamping control rod 31 rises, under the force generated by the reset of the elastic element 235, the triangular block 232 and the translation pusher 233 move away from the activated carbon filter plate 22 until the elastic element 235 is fully reset. This push-clamping structure utilizes the characteristics of the elastic element 235. During the clamping process, the elastic element 235 can effectively buffer the movement of the translation pusher 233, thereby avoiding damage to the activated carbon filter plate 22 due to rigid collisions. Meanwhile, the reset function of the elastic element 235 ensures that the flat-push clamping structure can accurately return to the initial position each time the clamp is released, making full preparation for the next clamping operation, which greatly improves the repeatability and accuracy of the operation.

[0032] In this embodiment, the end of the translation push rod 233 near the activated carbon filter plate 22 is provided with a clamping head 234. Correspondingly, the two sides of the activated carbon filter plate 22 are respectively provided with clamping grooves 221 that cooperate with the clamping head 234. It should be noted that both the clamping head 234 and the clamping groove 221 are hemispherical structures. The cooperation of the hemispherical clamping head 234 and the clamping groove 221 can increase the contact area, so that the clamping force can be more evenly distributed on both sides of the activated carbon filter plate 22.

[0033] In this embodiment, the top surface of the sealing plate 222 is provided with a handle 223. The purpose of providing the handle 223 is to make it easier to pick up and put down the activated carbon filter plate 22.

[0034] In this embodiment, at least one activated carbon filter plate 22 is provided, and the flat-push clamping structure and the card holder 21 are all configured correspondingly to the activated carbon filter plate 22. The arrangement of multiple activated carbon filter plates 22 can flexibly increase the adsorption area according to actual needs, thereby effectively improving the adsorption efficiency and well meeting the application scenarios with different processing capacities and requirements.

[0035] like Figure 1 and Figure 3 As shown, a guide plate 41 is provided on the inner wall of the tank 10 near the air inlet 11, and at least one guide vane 42 is mounted on the guide plate 41. In this embodiment, the guide plate 41 is a fine mesh grid plate, and there are two guide vanes 42. A protective cover 43 is provided on the side of the guide vane 42 near the air inlet 11. The guide plate 41 enables the exhaust gas to enter the area where the activated carbon filter plate 22 is located evenly, thereby effectively improving the utilization rate of the activated carbon filter plate 22, enhancing the adsorption efficiency, and extending the service life of the activated carbon filter plate 22, thus improving the performance of the entire activated carbon adsorption device. The fine mesh grid plate structure of the guide plate 41 can initially distribute the intake air evenly, disperse large particles in the airflow, and prevent them from directly impacting the activated carbon filter plate 22 and causing blockage or wear. Driven by the airflow, the guide vane 42 rotates, further dispersing the airflow evenly in all directions, allowing the exhaust gas to come into more thorough contact with the activated carbon filter plate 22, thus improving the adsorption effect of the activated carbon on harmful substances in the exhaust gas. The protective cover 43 protects the guide vane 42 from interference from external objects, ensuring its normal rotation, maintaining the stability of the guiding effect, and extending the service life of the guiding components, thereby ensuring the long-term adsorption performance of the entire activated carbon adsorption device.

Derivations and modifications made by those skilled in the art based on the specific embodiments of this utility model also fall within the protection scope of this utility model.
