Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment equipment, in particular to a multi-level activated carbon adsorption device. Background Art

[0002] Activated carbon is mainly used to absorb pollutants and impurities in the air. Its strong adsorption capacity makes it an effective means of purifying waste gas and adsorbing impurities. In addition, activated carbon has the characteristics of being renewable and reusable, which not only helps to save resources, reduce waste and avoid secondary pollution, but also brings cost savings to enterprises; therefore, activated carbon has a significant effect in treating impurities in the air;

[0003] In order to improve the adsorption effect, the existing adsorption device usually has multiple layers of activated carbon adsorption filter plates, and most of these activated carbon adsorption filter plates are fixedly arranged inside the adsorption device, which results in a constant distance between the two filter plates, that is, a constant filtration resistance generated between the two filter plates. When the adsorption device needs to increase the filtration wind speed in the device, it is necessary not only to increase the power of the external fan, but also to adjust the distance between the two filter plates so that the filter chamber between the two filter plates is enlarged. When the filtration resistance needs to be increased according to actual conditions, it is still necessary to adjust the setting position of the filter plate again. Traditionally, the filter plate is mostly adjusted by disassembling and then reinstalling, which has many steps and a long operation time. For this reason, a multi-layer activated carbon adsorption device is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a multi-layer activated carbon adsorption device, which solves the technical problem that the setting distance between the traditional multi-layer filter plates is constant, thereby resulting in a constant filtration resistance.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a multi-level activated carbon adsorption device, comprising an adsorption treatment box, wherein two partition plates are arranged in the adsorption treatment box, and the two partition plates divide the interior of the adsorption treatment box from bottom to top into an air inlet chamber, a treatment chamber, and an air outlet chamber which are interconnected;

[0006] A circular processing shell is connected to the processing chamber, a support column is fixed in the circular processing shell, four fixed frames are rotatably provided on the support column, the four fixed frames are distributed in a spoke-like manner, an activated carbon adsorption plate is provided in the fixed frame, and an adjustment component for adjusting the rotation angle of the four activated carbon adsorption plates is provided in the circular processing shell.

[0007] Further, the adjustment assembly includes a shell arranged in the circular processing shell, a push plate is slidably arranged in the shell, a driving rod is slidably arranged on the shell, one end of the driving rod is fixedly connected to the push plate, and a compression spring is sleeved on the driving rod for compressing the push plate;

[0008] The driving rod is provided with a first driving block and a second driving block, and the first driving block and the second driving block are both rotatably provided with two rotating rods, and the four fixed frames are each provided with a driving member, and the ends of the four rotating rods are respectively rotatably provided with four driving members;

[0009] The upper end of the driving rod passes through the adsorption treatment box and is provided with an adjusting sleeve through a threaded connection, which is used to adjust the setting height of the driving rod.

[0010] Furthermore, the two partition plates are provided with strip-shaped connecting holes for interconnecting the air outlet chamber and the processing chamber as well as the air inlet chamber and the processing chamber. The adsorption treatment box is provided with an air inlet pipe and an air outlet pipe. An air guide plate is also provided between the partition plate and the circular treatment shell for guiding the flow of exhaust gas.

[0011] Furthermore, the fixing frame is provided with two protrusions, and the inner wall of the adsorption treatment box is provided with limiting holes used in conjunction with the two protrusions.

[0012] Furthermore, the rotation angle range of the fixing frame is between 0° and 15°.

[0013] Furthermore, the inner wall of the circular processing shell is provided with a plurality of air inlets and air outlets, and the shell is interconnected with one of the air inlets.

[0014] By means of the above technical solution, the utility model provides a multi-layer activated carbon adsorption device, which has at least the following beneficial effects:

[0015] 1. The utility model adds an adjustment component between multiple activated carbon adsorption plates, and then can adjust the rotation angle of the multiple activated carbon adsorption plates inside the circular processing shell through the adjustment component, thereby changing the relative distance between the lower activated carbon adsorption plate and the upper activated carbon adsorption plate inside the circular processing shell, that is, changing the filtration resistance inside the circular processing shell. When it is necessary to reduce or increase the filtration resistance, it is only necessary to rotate the adjustment sleeve to achieve the adjustment. Compared with the traditional method of disassembling the activated carbon adsorption plate and then installing it again to adjust the filtration resistance, the setting of the adjustment component can greatly reduce the work intensity of the operator, and solves the disadvantages of the cumbersome adjustment of the traditional activated carbon adsorption plate.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] Please refer to Figure 1-Figure 6 A multi-level activated carbon adsorption device includes an adsorption treatment box 1, wherein two partition plates 101 are arranged in the adsorption treatment box 1, and the two partition plates 101 divide the interior of the adsorption treatment box 1 from bottom to top into an air inlet chamber, a treatment chamber, and an air outlet chamber that are interconnected;

[0027] A circular processing shell 2 is connected to the processing chamber, a support column 201 is fixedly provided in the circular processing shell 2, four fixed frames 202 are rotatably provided on the support column 201, the four fixed frames 202 are distributed in a spoke-like manner, an activated carbon adsorption plate 3 is provided in the fixed frame 202, and an adjustment component 4 for adjusting the rotation angle of the four activated carbon adsorption plates 3 is provided in the circular processing shell 2;

[0028] Furthermore, strip-shaped connecting holes are provided on the two partition plates 101 for connecting the air outlet chamber and the processing chamber and the air inlet chamber and the processing chamber to each other, an air inlet pipe and an air outlet pipe are provided on the adsorption processing box 1, and an air guide plate 102 is provided between the partition plate 101 and the circular processing shell 2 for guiding the flow of the exhaust gas;

[0029] Furthermore, two protrusions 2021 are provided on the fixing frame 202, and the inner wall of the adsorption treatment box 1 is provided with limiting holes for matching the two protrusions 2021; this arrangement enables the fixing frame 202 to rotate on the support column 201, thereby enabling the activated carbon adsorption plate 3 disposed in the fixing frame 202 to rotate, and the two activated carbon adsorption plates 3 on one side of the inner side of the circular treatment shell 2 to rotate to adjust the size of the filter chamber, and the specific adjustment method is controlled by the adjustment component 4;

[0030] The flow trajectory of the exhaust gas inside the adsorption treatment box 1 is as follows: the exhaust gas enters the air inlet cavity at the bottom of the adsorption treatment box 1 through the air inlet pipe on the lower side of the adsorption treatment box 1. After entering the air inlet cavity, the exhaust gas passes through the partition plate 101 set at the bottom and then enters the circular treatment shell 2. Since a plurality of activated carbon adsorption plates 3 are arranged inside the circular treatment shell 2, the exhaust gas passing through the plurality of activated carbon adsorption plates 3 is then adsorbed and treated, and finally discharged from the circular treatment shell 2 into the air outlet cavity, and further discharged to the outside through the air outlet pipe on the upper side of the adsorption treatment box 1. During the flow of the exhaust gas, the exhaust gas enters the circular treatment shell 2. It will be adsorbed by the activated carbon adsorption plate 3. When it is necessary to adjust the filtration resistance inside the circular treatment shell 2, the distance between the two activated carbon adsorption plates 3 at the bottom of the circular treatment shell 2 and the two activated carbon adsorption plates 3 at the top of the circular treatment shell 2 can be increased by adjusting the component 4, that is, the filter chamber formed by the upper and lower activated carbon adsorption plates 3 and the inner wall of the circular treatment shell 2 becomes larger, thereby reducing the resistance during filtration and then increasing the filtration speed. If you want to reduce the exhaust gas filtration speed, you only need to reduce the filter chamber formed by the upper and lower activated carbon adsorption plates 3 and the inner wall of the circular treatment shell 2.

[0031] Embodiment 2

[0032] Please refer to Figure 2-Figure 6 This embodiment is basically the same as the first embodiment. This embodiment is made on the basis of the first embodiment and has the same beneficial effects as the first embodiment. The same parts can be referred to each other and will not be described in detail here.

[0033] As a further technical solution of this embodiment, the adjustment assembly 4 further includes a shell 401 arranged in the circular processing shell 2, a push plate 402 is slidably arranged in the shell 401, a driving rod 403 is slidably arranged on the shell 401, one end of the driving rod 403 is fixedly connected to the push plate 402, and a pressing spring 404 is sleeved on the driving rod 403 for pressing the push plate 402;

[0034] The driving rod 403 is provided with a first driving block 405 and a second driving block 406, and two rotating rods 407 are rotatably provided on the first driving block 405 and the second driving block 406. The four fixed frames 202 are provided with driving members 408, and the ends of the four rotating rods 407 are rotatably provided with four driving members 408 respectively.

[0035] The upper end of the driving rod 403 passes through the adsorption treatment box 1 and is provided with an adjusting sleeve 103 through a threaded connection, which is used to adjust the setting height of the driving rod 403. Due to the setting of the squeezing spring 404, in the initial state, the squeezing spring 404 firmly squeezes the pushed plate 402, thereby making the driving rod 403 in the lower position. At this time, the lower end surface of the adjusting sleeve 103 abuts against the upper end surface of the adsorption treatment box 1. When the adjusting sleeve 103 is rotated, the position of the adjusting sleeve 103 remains unchanged, thereby pulling the driving rod 403 to move upward, thereby realizing the change of the position of the driving rod 403;

[0036] Furthermore, the inner wall of the circular processing shell 2 is provided with a plurality of air inlets and air outlets, and the shell 401 is interconnected with one of the air inlets;

[0037] Furthermore, the rotation range of the fixed frame 202 is between 0° and 15°. For the activated carbon adsorption plate 3 in the fixed frame 202, when the activated carbon adsorption plate 3 does not rotate, that is, the rotation angle is 0°, the filter chamber formed between the upper and lower activated carbon adsorption plates 3 on the same side of the circular processing shell 2 is the largest. When the activated carbon adsorption plate 3 is at the extreme position, that is, the rotation angle is 15°, the filter chamber formed between the two adjacent activated carbon adsorption plates 3 is the smallest.

[0038] As can be seen from the above, the specific working principle of the adjustment component 4 in the utility model is: when the filtration speed in the adsorption treatment box 1 needs to be increased, the adjustment sleeve 103 is rotated so that the driving rod 403 moves downward to the limit position (such as Figure 4 As shown), at this time, the first driving block 405 and the second driving block 406 both move downward to the limit position, and the first driving block 405 and the second driving block 406 respectively drive the fixed frame 202 to rotate a certain angle through the rotating rod 407. For the two fixed frames 202 at the upper part of the circular processing shell 2, the second driving block 406 moves downward and drives the two fixed frames 202 at the upper part to rotate toward the center. For the two fixed frames 202 at the lower part of the circular processing shell 2, the first driving block 405 moves downward and drives the two fixed frames 202 at the lower part to rotate toward the center. This causes the two activated carbon adsorption plates 3 on the same side of the circular processing shell 2 to rotate in the opposite direction for a certain distance, thereby increasing the relative distance between the two activated carbon adsorption plates 3, thereby reducing the filtration resistance;

[0039] When the filtration speed in the adsorption treatment box 1 needs to be reduced, the adjusting sleeve 103 is rotated to make the driving rod 403 move upward to the limit position (such as Figure 6 As shown in the figure, the driving rod 403 moves upward so that the first driving block 405 and the second driving block 406 move upward by a certain distance. For the second driving block 406, the second driving block 406 moves upward so that the two rotating rods 407 arranged on the second driving block 406 are rotated to open a certain angle, thereby driving the two fixed frames 202 on the upper part of the circular processing shell 2 to rotate a certain angle, specifically, the fixed frame 202 on the upper part of the circular processing shell 2 is rotated downward;

[0040] For the first driving block 405, the first driving block 405 moves upward so that the two rotating rods 407 arranged on the second driving block 406 rotate a certain angle, thereby driving the two fixed frames 202 at the lower part of the circular processing shell 2 to rotate a certain angle, that is, the fixed frame 202 at the lower part of the circular processing shell 2 rotates upward a certain angle, thereby making the space between the lower activated carbon adsorption plate 3 and the upper activated carbon adsorption plate 3 smaller, that is, the filter chamber inside the circular processing shell 2 becomes smaller, and the large flow of exhaust gas first impacts the two lower activated carbon adsorption plates 3. Since the filter chamber becomes smaller, it is more difficult for the exhaust gas to pass through the two upper activated carbon adsorption plates 3, thereby increasing the filtration resistance, thereby reducing the filtration speed in the adsorption treatment box 1.

[0041] Each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other. For the above embodiments, since they are basically similar to the method embodiments, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiments.
