Description

Technical Field

[0001] This utility model relates to the technical field of activated carbon adsorption boxes, specifically a simple activated carbon adsorption box. Background Technology

[0002] In hazardous waste warehouses or certain industrial product processing areas, there is often a small amount of volatile organic compound (VOC) emissions. Although the amount of these VOC emissions is small, long-term accumulation may still pose potential hazards to the environment and human health. In order to effectively collect and treat these VOCs, and considering cost-effectiveness and ease of operation, simple activated carbon adsorption boxes have emerged.

[0003] Publication No. CN215388533U discloses an activated carbon adsorption box. This device uses paired guide plates to guide and constrain the rectangular protective frame of the adsorption component, preventing the adsorption component from moving erratically in the airflow direction. Then, a locking rod of the component slides vertically with a limiting hole in the rectangular protective frame, further preventing the adsorption component from moving erratically in a direction perpendicular to the airflow direction. This securely fixes the adsorption component, improving the stability of the device. The rectangular protective frame can be pulled longitudinally to slide through the storage opening for easy removal and placement, facilitating quick removal of the adsorption component for cleaning and remanufacturing the activated carbon-based adsorption mesh. This helps ensure the device has a highly efficient and stable adsorption effect. However, this patent still has the following problems in actual use:

[0004] The device uses paired guide plates to guide and constrain the rectangular protective frame of the adsorption component, preventing the adsorption component from moving erratically in the direction of airflow. Then, the limiting rod of the locking component slides vertically with the limiting hole of the rectangular protective frame, thus preventing the adsorption component from moving erratically in the direction perpendicular to the direction of airflow. This achieves a secure fixation of the adsorption component and improves the stability of the device. However, the device does not have an air conveying structure, which means that in some areas without ventilation equipment, external fans or other equipment are required to transport the gas in the area, which greatly reduces the efficiency of the device and causes inconvenience to the staff when using it.

[0005] A simple activated carbon adsorption box is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a simple activated carbon adsorption box to solve the problem mentioned in the background art. Currently, the rectangular protective frame that guides and constrains the adsorption component through paired guide plates, preventing the adsorption component from moving randomly in the direction of airflow, and then the limiting rod of the locking component slides vertically with the limiting hole of the rectangular protective frame to prevent the adsorption component from moving randomly in the direction perpendicular to the direction of airflow. This achieves a reliable fixation of the adsorption component and is beneficial to improving the stability of the device. However, this device does not have an air conveying structure, which means that in some cases where there is no ventilation equipment, external fans or other equipment are required to transport the gas in the area, thus greatly reducing the efficiency of the device.

[0010] Preferably, the limiting component includes a connecting plate fixedly installed at one end of the first frame and the second frame, and a limiting box is symmetrically embedded on one side of the housing. A toothed plate is slidably connected inside one side of the limiting box, and a gear is rotatably connected inside one side of the limiting box. One side of the toothed plate is meshed with the gear, and a movable rod is rotatably connected to the side of the gear away from the center. An insert plate is rotatably connected to the end of the movable rod away from the gear. Slots are symmetrically opened at both ends of the connecting plate, and the insert plate is inserted into the slot. A limiting block is symmetrically fixedly installed inside the insert plate, and limiting grooves are symmetrically opened inside the limiting box. The limiting block and the limiting groove are slidably connected.

[0011] Preferably, a dustproof net is fixedly connected to the inner bottom of the bend.

[0012] Preferably, the first conical tooth and the second conical tooth are engaged in a meshing connection.

[0013] Preferably, one end of the drive rod is fixedly connected to the motor.

[0014] Preferably, one end of the first frame and the second frame is inserted into a groove on one side of the support plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: A simple activated carbon adsorption box is described below: When the operator starts the motor, it drives the drive rod to rotate. Through the cooperation between the sprocket and the chain, it drives the rotation of two sets of transmission rods. The rotation of the transmission rods drives the rotation of two sets of second conical teeth, which in turn drives the rotation of the first conical teeth. The rotation of the two sets of rotating rods drives the rotation of the fan blades. When the fan blades rotate inside the first frame, a negative pressure is generated inside the first frame, allowing outside air to enter the first frame through the conical pipe and duct. At this time, two sets of filters and activated carbon filter plates filter harmful gases in the air. When the fan blades rotate inside the second frame, a negative pressure is generated inside the second frame, allowing the filtered gas to be discharged through the bend pipe. This effectively captures volatile organic compounds in the air, thereby achieving the purpose of air purification. Furthermore, it utilizes two sets of... The fan blade design enables autonomous air delivery and filtration, significantly improving air purification efficiency. This practical and highly efficient air purification system is particularly suitable for hazardous waste warehouses or product processing areas where low levels of volatile organic compounds are generated. By pressing two sets of toothed plates inside the limiting box, the movement of the toothed plates engages the gears, which in turn rotate the movable rod. This rotation then moves the insert plate, allowing it to engage with the slot. The insert plate then moves two sets of limiting blocks within the limiting groove. Tightening the fixing knob presses the toothed plates in place, quickly securing the limiting connecting plate. This facilitates the installation and disassembly of the first and second frames, as well as the maintenance and regeneration of the filter screen and activated carbon filter plates, greatly improving the daily maintenance efficiency of the device.

[0016] 1. The motor, started by the operator, drives the drive rod to rotate. Through the interaction of the sprocket and chain, this drives the rotation of two sets of transmission rods. The rotation of the transmission rods drives the rotation of two sets of second conical teeth, which in turn drives the rotation of the first conical teeth. The rotation of both sets of rotating rods drives the rotation of the fan blades. Because the blades on both sets of fan blades have the same surface design, when the fan blades inside the first frame rotate, a negative pressure is generated inside the first frame. This forces outside air into the first frame through the conical pipe and duct. At this point, two sets of filters and activated carbon filter plates filter harmful gases from the air. When the fan blades inside the second frame rotate, a negative pressure is generated inside the second frame, causing the filtered air to be discharged through a bend pipe. This effectively captures volatile organic compounds in the air, thus purifying the air. Furthermore, the design of the two sets of fan blades enables self-regulation. This device effectively filters and transports air, significantly improving air purification efficiency and achieving practical and efficient air purification. It is particularly suitable for handling hazardous waste warehouses or product processing areas where volatile organic compounds are relatively low. When air flows inside the bend, the gas compresses the rubber block, causing it to separate from the circular groove. The movement of the rubber block drives the movement of the circular plate, which in turn causes the sliding rod to slide inside the fixed tube. At this point, the first telescopic spring contracts, allowing the gas to exit through the circular groove and the air slot. When the fan blades stop rotating, the first telescopic spring quickly extends and resets, causing the rubber block to fit snugly against the circular groove. This prevents backflow of gas and effectively avoids impurities and dust from the outside air from entering the housing through the bend, greatly improving the protection of the housing and preventing water ingress, thus extending the device's lifespan.

[0017] 2. The operator inserts the first and second frames into the housing. One end of each frame engages with a groove on the support plate. The operator then presses down on two sets of toothed plates, which slide within the limiting box. This movement of the toothed plates engages the gears, which in turn rotate the movable rod. The rod's rotation then moves the insert plate, connecting it to the slot. The insert plate then moves the two limiting blocks within the limiting groove. The operator tightens the fixing knob, using one end to press and fix the toothed plates, thus quickly fixing the limiting connection plate. This facilitates the installation and disassembly of the first and second frames, as well as the maintenance and regeneration of the filter screen and activated carbon filter plate. This significantly improves the efficiency of daily maintenance and provides greater convenience for operators. Attached Figure Description

This also facilitates the maintenance and regeneration of the filter screen 204 and the activated carbon filter plate 205 by the staff, thereby greatly improving the daily maintenance efficiency of the device and bringing convenience to the staff during use.

[0030] Working principle: Before using this simple activated carbon adsorption box, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1- Figure 6 As shown, the worker first inserts the top of the duct 103 into the pre-drilled hole in the wall. The worker then starts the motor 213, which drives the drive rod 214 to rotate. The rotation of the drive rod 214 drives the sprocket 215 to rotate. Through the interaction between the sprocket 215 and the chain 216, the two sets of transmission rods 209 rotate. The rotation of the transmission rods 209 drives the two sets of second conical teeth 211 to rotate. The rotation of the second conical teeth 211 drives the rotation of the first conical teeth 210. The rotation of the first conical teeth 210 drives the rotation of the rotating rod 207. The rotation of the two sets of rotating rods 207 drives the rotation of the fan blades 208. Because the surfaces of the two sets of fan blades 208... With identical design, when the fan blades 208 inside the first frame 101 rotate, a negative pressure is generated inside the first frame 101. This forces outside air to enter the first frame 101 through the conical tube 105 and the duct 103. At this point, two sets of filters 204 filter particulate impurities from the air, and then the activated carbon filter plate 205 filters harmful gases. When the fan blades 208 inside the second frame 102 rotate, a negative pressure is generated inside the second frame 102. This forces the filtered air to exit through the bent pipe 104, effectively capturing volatile organic compounds in the air and achieving the goal of air purification. Furthermore, by utilizing the design of two sets of fan blades 208, it can achieve autonomous air delivery and filtration, greatly improving air purification efficiency and realizing practical and efficient air purification. It is particularly suitable for handling hazardous waste warehouses or product processing areas with low volatile organic compound production. When air flows inside the bend 104, the gas compresses the rubber block 224, causing it to separate from the circular groove 223. The movement of the rubber block 224 drives the movement of the circular plate 222, which in turn causes the slide rod 220 to slide inside the fixed tube 219. At this time, the first telescopic spring 221 contracts, allowing the gas to pass through the circular groove 223. 23 and air trough 218 are discharged. When the fan blade 208 stops rotating, the internal pressure of the bend 104 decreases. At this time, the first extension spring 221 quickly extends and resets, so that the rubber block 224 and the circular groove 223 fit together. This can prevent backflow of gas and effectively prevent impurities and dust in the external air from entering the box 1 through the bend 104. This can greatly improve the protection effect inside the box 1, prevent water from entering the box 1, extend the service life of the device, and bring practicality to the staff. The dustproof net 227 can block external dust and other substances.

[0031] The staff inserts the first frame 202 and the second frame 203 into the housing 1. At this time, one end of the first frame 202 and the second frame 203 are respectively inserted into the groove on one side of the support plate 201. Then, the staff presses the two sets of toothed plates 303 to slide inside the limiting box 302. At this time, the movement of the toothed plates 303 engages and drives the rotation of the gear 304. The rotation of the gear 304 drives the rotation of the movable rod 305. The rotation of the movable rod 305 drives the movement of the insertion plate 306. At this time, the insertion plate 306 is inserted into the slot 307. 6 drives the two sets of limiting blocks 308 to slide inside the limiting groove 309. Then, the operator tightens the fixing knob 310, and uses one end of the fixing knob 310 to press and fix the toothed plate 303, thereby achieving the effect of quickly fixing the limiting connecting plate 301. This makes it easier for the operator to install and disassemble the first frame 202 and the second frame 203, and facilitates the operator to repair and regenerate the filter screen 204 and the activated carbon filter plate 205. This greatly improves the daily maintenance efficiency of the device and brings convenience to the operator during use.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
