Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon adsorption boxes, in particular to an activated carbon adsorption box convenient for replacing filters. Background Technique

[0002] An activated carbon adsorption box is a device used to treat waste gas. At present, the waste gas emissions of many factories do not meet the emission standards. However, waste gas is definitely generated during the operation of factories. The problem of treating waste gas is a problem that factories must face. Therefore, factories need to use activated carbon adsorption boxes to treat waste gas problems. After the activated carbon adsorption box is used for a period of time, the filters inside it absorb a large amount of impurities and need to be replaced regularly. Otherwise, the purification ability of the waste gas will decline. Therefore, we introduce an activated carbon adsorption box convenient for replacing filters.

[0003] The existing patent (publication number: CN214715494U) discloses an activated carbon adsorption box convenient for replacing filters, including a device housing and a second filter plate. An air inlet is installed at the left end of the device housing, and a first filter plate is installed inside the device housing. A first sliding groove is provided at the bottom end of the first filter plate. A first slider is installed inside the first sliding groove, and a first clamping groove is installed inside the first filter plate. The bottom end of the first clamping block is connected with a first telescopic spring, and a first pushing block is installed inside the first clamping groove. The second filter plate is fixed inside the device housing, and a second sliding groove is installed at the bottom end of the second filter plate. A second clamping groove is installed inside the second filter plate, and a second clamping block is installed inside the second clamping groove. A second pushing block is installed inside the second clamping groove, and a third filter plate is installed inside the device housing. This activated carbon adsorption box convenient for replacing filters can filter gas. The existing technology has the following problems: 1. When replacing the internal filters of the existing activated carbon adsorption box, the filters need to be disassembled one by one, and the filter screens cannot be taken out all at once, resulting in very low efficiency; 2. The existing activated carbon adsorption boxes mainly use the activated carbon plates arranged linearly inside to treat and adsorb waste gas. However, the activated carbon plates closer to the air inlet are more likely to be saturated, resulting in different saturation degrees of multiple activated carbon plates. If all the activated carbon plates are replaced at once, the activated carbon plates far from the air inlet have low utilization rate, causing waste. If only the saturated activated carbon plates are replaced each time, the replacement frequency is too high, increasing the labor cost. Content of the Utility Model

[0024] In this embodiment, Figure 2 、 Figure 3 and Figure 6 As shown, the adsorption component 3 includes a motor 301 fixedly mounted on the inner bottom of the sliding box 2, the output end of the motor 301 is fixedly connected to the main pulley 302, the middle of the top surface of the main pulley 302 is fixedly connected to the rotating shaft 1 303, the outer surface of the rotating shaft 1 303 is fixedly connected to the mounting frame 304, the middle of the mounting frame 304 is plugged with an activated carbon plate 305, and the top of the rotating shaft 1 303 is fixedly connected to a cross top cover 1 306 by fastening screws; the rotating shaft 1 303 is driven to rotate by the motor 301, and the rotating shaft 1 303 drives the mounting frame 304 and the activated carbon plate 305 to rotate at the same time with the rotating shaft 1 303 as the axis. This structure enables each activated carbon plate 305 to evenly absorb harmful substances in the exhaust gas, making it convenient to replace all the activated carbon plates at one time. Compared with the traditional method of arranging the activated carbon plates 305 in a straight line, this method ensures that the harmful substance absorption saturation of each activated carbon plate 305 is consistent, and there will be no problem of low utilization rate caused by low saturation of some activated carbon plates 305. The cross top cover 306 can fix the activated carbon plate 305 in the installation frame 304 to prevent the activated carbon plate 305 from falling out of the installation frame 304. At the same time, when the activated carbon plate 305 needs to be replaced, it is only necessary to unscrew the fastening screws from the top of the rotating shaft 303 to remove the cross top cover 306. At this time, the activated carbon plate 305 can be pulled out of the installation frame 304 for replacement. This structure can contact and lock all activated carbon plates 305 at the same time, and the replacement efficiency is higher.

[0025] In this embodiment, Figure 1 、 Figure 4 and Figure 5As shown in the figure, a handle 201 and two L-shaped rods 202 are respectively welded on one side of the sliding box 2. Two groups of fixing plates 203 are provided on the bottom surface of the sliding box 2. Two rollers 204 are rotatably connected to the middle of each group of fixing plates 203. An arc-shaped groove 205 is formed on one side of each group of fixing plates 203 away from the middle roller 204 of this group. Both groups of fixing plates 203 are slidably connected to the inside of the chute 7 through the rollers 204, and the inside of the arc-shaped groove 205 is fitted with the abutting block 10; the rollers 204 can facilitate the pulling out and pushing in of the sliding box 2 from the box body 1. When the activated carbon plates 305 need to be replaced, all the activated carbon plates 305 can be taken out of the box body 1 at one time for convenient replacement. The chute 7 can play a guiding role for the sliding box 2 to prevent deviation in position when installing the sliding box 2. The abutting block 10 can, under the action of the spring 9, push the abutting block 10 into the arc-shaped groove 205 when the sliding box 2 is pushed into the required position in the box body 1, playing a pre-fixing role for the sliding box 2, so that the staff can rotate the cross bar 11 into the gap between the L-shaped rod 202 and the sliding box 2 to limit the sliding box 2 and prevent the sliding box 2 from coming out of the box body 1.

[0026] In this embodiment, as Figure 2 shown, an installation cavity 206 is formed on the inner bottom of the sliding box 2. The motor 301 and the main pulley 302 are both arranged inside the installation cavity 206, and the top end of the first rotating shaft 303 extends to the outside of the installation cavity 206; by driving the main pulley 302 and the first rotating shaft 303 to rotate through the motor 301, the first rotating shaft 303 can drive the four groups of activated carbon plates 305 to rotate to absorb harmful substances in the waste gas, and the main pulley 302 can drive the drying assembly 4 to rotate through a belt to dehumidify the waste gas entering the box body 1.

[0027] In this embodiment, as Figure 2 and Figure 3As shown, the drying component 4 includes a secondary pulley 401 movably connected to the main pulley 302 through a belt, a second rotating shaft 402 is passed through the middle of the secondary pulley 401, and a drying plate 403 is fixedly connected to the outer surface of the second rotating shaft 402. The drying plate 403 is hollow in design, and the bottom end of the second rotating shaft 402 is rotatably connected to the inner bottom surface of the installation cavity 206. A plurality of holes are provided on the surface of the drying plate 403, and the interior of the drying plate 403 is filled with dry particles. The top of the second rotating shaft 402 is fixedly connected to the second cross top cover 404 by fastening screws; The wheel 401 rotates with the shaft 2 402 driven by the main pulley 302, and the shaft 2 402 drives the drying plate 403 to rotate, and the dry particles in the drying plate 403 are used to dry the exhaust gas entering the box body 1. Because the moisture in the exhaust gas is too heavy, the absorption rate of the activated carbon plate 305 to harmful substances will be greatly reduced. The cross top cover 2 404 installed on the top of the shaft 2 402 by fastening screws can block the top opening of the drying plate 403 to prevent the dry particles from flying out of the top opening of the drying plate 403.

[0028] The usage and advantages of this utility model: When the activated carbon adsorption box with convenient filter element replacement is used, the working process is as follows:

[0029] The exhaust gas enters the box body 1 from the air inlet 5, and first passes through the drying component 4 to absorb the moisture in the exhaust gas, thereby reducing the moisture in the exhaust gas and avoiding the low absorption rate of the activated carbon plate 305 on the harmful substances in the exhaust gas due to the high humidity of the exhaust gas, which ultimately leads to incomplete exhaust gas purification. The exhaust gas after passing through the drying component 4 will continue to move towards the adsorption component 3, and the motor 301 drives the four groups of activated carbon plates 305 to rotate to absorb the harmful substances in the exhaust gas. This structure enables each activated carbon plate 305 to evenly absorb the harmful substances in the exhaust gas, making it convenient to replace all the activated carbon plates 305 at one time. Compared with the traditional method of arranging the activated carbon plates 305 in a straight line, this method This method ensures that the harmful substance absorption saturation of each activated carbon plate 305 is consistent, and there will be no problem of low utilization rate caused by low saturation of some activated carbon plates 305. The cross top cover 306 can fix the activated carbon plate 305 in the installation frame 304 to prevent the activated carbon plate 305 from falling out of the installation frame 304. At the same time, when the activated carbon plate 305 needs to be replaced, it is only necessary to unscrew the fastening screw from the top of the rotating shaft 303 to remove the cross top cover 306. At this time, the activated carbon plate 305 can be pulled out of the installation frame 304 for replacement. This structure can contact the lock of all activated carbon plates 305 at the same time, and the replacement efficiency is higher.
