Description

Technical Field

[0001] This utility model belongs to the field of VOC treatment technology, and in particular relates to a VOC activated carbon adsorption treatment box. Background Technology

[0002] VOCs, or volatile organic compounds, are a collective term for volatile organic compounds. They are frequently generated in manufacturing enterprises, such as printing plants (inks), paint booths, rubber factories, and pharmaceutical plants. These gases require treatment using activated carbon adsorption boxes, which offer advantages such as high adsorption efficiency, wide applicability, easy maintenance, and the ability to simultaneously treat multiple mixed waste gases.

[0003] Existing VOC activated carbon adsorption boxes often exhibit uneven activated carbon absorption during waste gas treatment. After a period of use, some activated carbon particles in the treatment box become nearly saturated, while others can continue to function normally. If continued use is attempted, the nearly saturated activated carbon particles in the waste gas path will affect the treatment effect, while directly replacing the activated carbon will result in some waste.

[0004] Therefore, we propose a VOC activated carbon adsorption treatment box to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of uneven activated carbon absorption in the prior art, and to propose a VOC activated carbon adsorption treatment box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A VOC activated carbon adsorption treatment box includes a box body, wherein at least one adsorption unit is provided inside the box body.

[0008] The adsorption unit includes an adsorption box that is detachably installed inside the box. The top surface of the adsorption box is open and the bottom surface has ventilation holes. The adsorption box is filled with activated carbon particles. An installation frame is movable above the adsorption box. A movable plate is rotatably installed at the bottom of the installation frame. Multiple fixing teeth for turning the activated carbon particles are fixedly connected to the bottom end of the movable plate. A limiting component for limiting the rotation angle of the movable plate is provided on the side of the installation frame. A tension rope is fixedly connected to one side of the movable plate. The other end of the tension rope extends to the outside of the box and is fixedly connected to a handle.

[0009] An arc-shaped auxiliary block is fixedly connected to the inner wall of the box body on the side away from the handle. The two sides of the box body are provided with reset components that drive the mounting bracket to move toward the auxiliary block. A magnet assembly that attracts each other is provided between the side wall of the box body away from the handle and the mounting bracket.

[0010] Preferably, the limiting component includes a limiting rod fixedly connected to the mounting bracket, and the side of the movable plate has an arc-shaped groove for the limiting rod to be inserted, with the bottom end of the arc-shaped groove located directly below the rotation axis of the movable plate.

[0011] Preferably, the inner walls on both sides of the housing are provided with sliding grooves, and the mounting bracket is slidably disposed in the two sliding grooves on both sides. The reset component includes an elastic rope with one end fixedly disposed at the end of the sliding groove away from the auxiliary block, a pulley fixedly installed at the end of the sliding groove near the auxiliary block, and the other end of the elastic rope being fixedly connected to the side of the mounting bracket after passing around the pulley.

[0012] Preferably, the magnet assembly includes a first magnet fixedly connected to the side of the mounting bracket away from the handle, and a second magnet that cooperates with the first magnet fixedly connected to the inner side wall of the housing.

[0013] Preferably, when the first magnet is attached to the second magnet, the bottom end of the fixing tooth is higher than the top end of the adsorption box; when the moving plate is separated from the auxiliary block, the bottom end of the fixing tooth is lower than the top end of the adsorption box.

[0014] Preferably, the handle is detachably threaded onto the outer wall of the housing.

[0015] In summary, the technical effects and advantages of this utility model are as follows: This VOC activated carbon adsorption treatment box uses a pull rope to move a movable plate, which in turn moves the fixed teeth on the movable plate and flips the activated carbon particles in the adsorption box. Through the auxiliary block, in conjunction with the reset component and the magnet component, the mounting frame and the movable plate are stably stored and placed. Compared with existing devices, this avoids the problem of uneven activated carbon absorption affecting the absorption effect, and improves practicality and waste gas treatment effect.

[0022] 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.

[0023] Reference Figure 1-2 A VOC activated carbon adsorption treatment box includes a box body 1, and at least one adsorption unit is provided inside the box body 1.

[0024] Reference Figure 2-4 The adsorption unit includes an adsorption box 2 that is detachably installed inside the housing 1. The top surface of the adsorption box 2 is open and the bottom surface has ventilation holes 3. The adsorption box 2 is filled with activated carbon particles 4. An installation frame 5 is movable above the adsorption box 2. A movable plate 6 is rotatably installed at the bottom of the installation frame 5. Multiple fixing teeth 7 for turning the activated carbon particles 4 are fixedly connected to the bottom end of the movable plate 6. A limiting component for limiting the rotation angle of the movable plate 6 is provided on the side of the installation frame 5. A tension rope 8 is fixedly connected to one side of the movable plate 6. The other end of the tension rope 8 extends to the outside of the housing 1 and is fixedly connected to a handle 9.

[0025] An arc-shaped auxiliary block 10 is fixedly connected to the inner wall of the box 1 on the side away from the handle 9. The box 1 has a reset component on both sides that drives the mounting bracket 5 to move toward the auxiliary block 10. There is a magnet component that attracts each other between the side wall of the box 1 away from the handle 9 and the mounting bracket 5.

[0026] Reference Figure 3-5 In this VOC activated carbon adsorption treatment box, when treating waste gas, the waste gas enters from the bottom of the adsorption box 2, passes through the vent 3 into the adsorption box 2, the VOC is adsorbed by the activated carbon, and after being treated by multiple adsorption units, the treated gas is discharged from the top of the adsorption box 2.

[0027] After a period of use, hold the handle 9 and pull the tension rope 8. The tension rope 8 pulls the moving plate 6 to rotate and move until the moving plate 6 is in a vertical position. At this time, the fixing teeth 7 are inserted into the adsorption box 2. Continue to pull the tension rope 8, and the moving plate 6 and the mounting frame 5 move accordingly. The fixing teeth 7 then turn the activated carbon particles 4.

[0028] After the flipping is completed, the reset component drives the mounting bracket 5 to move toward the auxiliary block 10 until the moving plate 6 is in contact with the auxiliary block 10. At this time, the mounting bracket 5 continues to move, and the auxiliary block 10 drives the moving plate 6 to rotate until the magnet component fixes the mounting bracket 5 to the side wall of the box 1. At this time, a new round of exhaust gas treatment can be carried out, or the adsorption box 2 can be replaced.

[0029] Reference Figure 3-5 The limiting component includes a limiting rod 11 fixedly connected to the mounting frame 5. The side of the moving plate 6 has an arc-shaped groove 12 for the limiting rod 11 to be inserted, and the bottom end of the arc-shaped groove 12 is located directly below the rotation axis of the moving plate 6. The limiting component limits the moving plate 6 through the limiting rod 11. When the limiting rod 11 is at the top of the arc-shaped groove 12, the moving plate 6 is in a vertical state, and the fixing teeth 7 are inserted into the adsorption box 2 and turn the activated carbon particles 4 as the mounting frame 5 moves. When the limiting rod 11 is at the bottom of the arc-shaped groove 12, the moving plate 6 is in a horizontal state to avoid affecting the replacement of the adsorption box 2.

[0030] The inner walls on both sides of the housing 1 are provided with sliding grooves 13. The mounting bracket 5 is slidably disposed in the two sliding grooves 13 on both sides. The reset component includes an elastic rope 14 with one end fixedly disposed at the end of the sliding groove 13 away from the auxiliary block 10. A pulley 15 is fixedly installed at the end of the sliding groove 13 near the auxiliary block 10. The other end of the elastic rope 14 is wrapped around the pulley 15 and fixedly connected to the side of the mounting bracket 5.

[0031] Reference Figure 3-5 The magnet assembly includes a first magnet 16 fixedly connected to the side of the mounting bracket 5 away from the handle 9, and a second magnet 17 that cooperates with the first magnet 16 fixedly connected to the inner wall of the housing 1. The stability of the mounting bracket 5 when it is placed is improved by the mutual attraction between the first magnet 16 and the second magnet 17.

[0032] When the first magnet 16 is attached to the second magnet 17, the bottom of the fixing tooth 7 is higher than the top of the adsorption box 2, so as to facilitate the replacement of the adsorption box 2 and avoid collision between the adsorption box 2 and the fixing tooth 7 when it is replaced; when the moving plate 6 is separated from the auxiliary block 10, the bottom of the fixing tooth 7 is lower than the top of the adsorption box 2, so as to realize the turning of the activated carbon particles 4 inside the adsorption box 2 by the fixing tooth 7.

[0033] Reference Figure 3 The handle 9 is detachably threaded onto the outer wall of the housing 1, which makes it easier to place the handle 9. At the same time, the detachable threaded connection also facilitates the setting of the airtightness of the housing 1. A sealing ring can be set at the threaded end of the handle 9. This sealing ring sealing method is existing technology and will not be described in detail.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
