Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to an external activated carbon box. Background Technique

[0002] The integrated external activated carbon box utilizes the dual characteristics of physical adsorption and chemical adsorption of activated carbon. Through special pore size adjustment technology, it has a pore structure matching the size of indoor harmful gas molecules, completely adsorbing harmful gases instead of covering or weakening odors, and fundamentally and thoroughly removing indoor pollution. On the inner wall of its micropores, nano-photocatalyst is loaded by high-tech process, which can effectively decompose the adsorbed toxic and harmful gases into low-molecular gases, carbon dioxide and water, so as to achieve the purpose of purifying air. The existing integrated external activated carbon box generally has a simple structure and poor functionality. It is very inconvenient to place and replace the activated carbon. It is necessary to manually pull out the activated carbon frame, wasting manpower and time and slowing down the speed of replacing the activated carbon. The "integrated external activated carbon box" disclosed in the application number "CN201820033218.0" solves the problem of the simple structure and poor functionality of the previous integrated external activated carbon box through specific technical structure settings. However, there are still many defects in actual use. For example, the activated carbon placement frame placed in the main body of the activated carbon box is taken out by using a convenient installation structure. However, the utility model cannot be used during this period of replacing the activated carbon, reducing the waste gas treatment efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide an external activated carbon box to solve the problems put forward in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical scheme: An external activated carbon box, including a box body, a first bracket and a second bracket. The top end inside the box body is fixed with a first bracket. The bottom end inside the first bracket is penetrated and provided with a first air hole, and the bottom end outside the first bracket is provided with a first air inlet duct. The bottom end inside the box body is fixed with a second bracket. The bottom end inside the second bracket is penetrated and provided with a second air hole, and the top end outside the second bracket is provided with a second air inlet duct. A partition is fixed between the second bracket and the first bracket. A cylinder is fixed on one side inside the box body, and a baffle is fixed at the output end of the cylinder. A first box body is placed inside the first bracket, and activated carbon is filled inside the first box body. A second box body is placed inside the second bracket, and activated carbon is filled inside the second box body.

[0005] When using an external activated carbon box in this technical solution, the waste gas enters the interior of the box through the air inlet, is guided through the partition and transmitted to the interior of the first air inlet duct. When entering the interior of the first air inlet duct, it passes through the first air holes and is transmitted to the interior of the first box body. After being adsorbed and filtered by the activated carbon placed inside the first box body, it is transmitted to the interior of the air outlet. Finally, the treated waste gas is discharged from the air outlet. When the activated carbon in the first box body needs to be replaced, the staff controls the air cylinder to push the baffle fixed at the output end. The baffle blocks the first air inlet duct and opens the second air inlet duct. At this time, the waste gas entering the box through the air inlet will be guided through the partition and transmitted to the interior of the second air inlet duct, and then pass through the activated carbon placed inside the second box body. The activated carbon placed inside the second box body adsorbs and filters it. The treated waste gas is transmitted to the interior of the air outlet through the second air holes and is finally discharged from the air outlet. When the activated carbon in the second box body is treating the waste gas, the staff can pull out the first box body placed in the first bracket and replace the activated carbon placed inside it. In this way, the activated carbon can be replaced without stopping the machine, and the efficiency of waste gas treatment can be improved by alternating use.

[0006] Preferably, an air inlet is provided on one side of the exterior of the box body, and an air outlet is provided on the other side of the exterior of the box body. Through the cooperation of the air inlet and the air outlet, the waste gas can enter the box for treatment and then be discharged, achieving the effects of air intake and air outlet.

[0007] Compared with the prior art, the beneficial effects of the present utility model are:

[0008] 1. By setting the first bracket and the second bracket, the first box body and the second box body filled with activated carbon can be placed on their surfaces. The baffle is pushed by the air cylinder to switch the waste gas transmission to the interior of the first air inlet duct or the interior of the second air inlet duct, so that the activated carbon in the first box body and the second box body can be used alternately. In this way, when replacing the activated carbon, it is ensured that the present utility model does not stop treating the waste gas, improving the treatment efficiency.

[0014] Embodiment 1

[0015] As Figure 1 、 Figure 2 and Figure 3 shown, an external activated carbon box proposed by the present utility model includes a box body 2, a first bracket 3 and a second bracket 12. The top end inside the box body 2 is fixedly provided with the first bracket 3. The bottom end inside the first bracket 3 is penetrated and provided with a first air hole 6, and the bottom end outside the first bracket 3 is provided with a first air intake duct 5. The bottom end inside the box body 2 is fixedly provided with the second bracket 12. The bottom end inside the second bracket 12 is penetrated and provided with a second air hole 9. The top end outside the second bracket 12 is provided with a second air intake duct 10. A partition board 7 is fixedly provided between the second bracket 12 and the first bracket 3. A cylinder 13 is fixedly provided on one side inside the box body 2. The output end of the cylinder 13 is fixedly provided with a baffle 14. A first box body 4 is placed inside the first bracket 3, and activated carbon 15 is filled inside the first box body 4. A second box body 11 is placed inside the second bracket 12, and activated carbon 15 is filled inside the second box body 11.

[0016] Its exhaust gas enters the interior of the box body 2 through the air inlet 1, is guided through the partition plate 7 and transmitted to the interior of the first air inlet duct 5. When entering the interior of the first air inlet duct 5, it passes through the first air holes 6 and is transmitted to the interior of the first box body 4. After being adsorbed and filtered by the activated carbon 15 placed inside the first box body 4, it is transmitted to the interior of the air outlet 8. Finally, the processed exhaust gas is discharged from the air outlet 8. When the activated carbon 15 inside the first box body 4 needs to be replaced, the staff controls the cylinder 13 to push the baffle 14 fixed at the output end. The baffle 14 blocks the first air inlet duct 5 and opens the second air inlet duct 10. At this time, the exhaust gas entering the box body 2 through the air inlet 1 will be guided through the partition plate 7 and transmitted to the interior of the second air inlet duct 10, and then pass through the activated carbon 15 placed inside the second box body 11. The activated carbon 15 placed inside the second box body 11 adsorbs and filters it. The processed exhaust gas is transmitted to the interior of the air outlet 8 through the second air holes 9, and finally is discharged by the air outlet 8. When the activated carbon 15 inside the second box body 11 is treating the exhaust gas, the staff can pull out the first box body 4 placed inside the first bracket 3 and replace the activated carbon 15 placed inside it. In this way, the activated carbon 15 can be replaced without shutting down the machine, and the efficiency of exhaust gas treatment can be improved by alternating use.
