An easily adjustable activated carbon adsorption box

Abstract

This application discloses an easily adjustable activated carbon adsorption box, relating to the field of activated carbon adsorption box technology. It includes a box body and working components. The working components provide a functional structure that can change the spacing of the activated carbon blocks, adapting to fluctuations in exhaust gas concentration and easily handling differences in exhaust gas composition. Rotating the rotating sleeve causes it to move vertically on the fixed screw, changing the vertical position of the moving frames. This adjusts the distribution of multiple moving frames on the fixed screw, altering the spacing of the activated carbon blocks. Outside air enters the box through the inlet pipe, passes through a dust filter to remove large particles, and is guided by a flow-limiting frame. After being adsorbed by the activated carbon blocks, the purified air is discharged through the outlet pipe. The support frame is pulled outwards by the handle, and the support frame is then removed from the moving frame. The activated carbon blocks filling the inside of the support frame can be easily replaced. The load-bearing mesh plate supports the activated carbon blocks while ensuring airflow.

Description

Technical Field

[0001] This utility model relates to the field of activated carbon adsorption box technology, and in particular to an activated carbon adsorption box that is easy to adjust. Background Technology

[0002] Activated carbon adsorption boxes mainly utilize the physical adsorption properties of activated carbon to remove pollutants from waste gas. Activated carbon has a huge specific surface area and abundant microporous structure. These micropores can generate strong adsorption force. When waste gas passes through the activated carbon adsorption box, the harmful gas molecules in the waste gas will be adsorbed on the surface of the micropores of the activated carbon, thereby purifying the discharged gas. It is widely used in furniture wood industry, chemical coating, metal surface treatment and other places that generate organic waste gas and odors such as spraying, painting and drying.

[0003] However, most activated carbon adsorption boxes currently have a fixed activated carbon adsorption layer, which cannot adjust the spacing between multiple activated carbon layers, resulting in insufficient adaptability to different concentrations of waste gas environments.

[0004] To address these issues, we have developed an easily adjustable activated carbon adsorption box. Utility Model Content

[0005] The purpose of this invention is to provide an easily adjustable activated carbon adsorption box to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable activated carbon adsorption box, comprising a box body and a working component. The working component is installed inside the box body. The working component includes a flow guiding and limiting frame fixedly connected inside the box body. A support frame is slidably connected to the inner side of the flow guiding and limiting frame through a slot. A fixing screw is fixedly connected to the inner side of the support frame. A rotating sleeve is threadedly connected to the surface of the fixing screw. A movable frame is rotatably connected to the outer side of the rotating sleeve through a slot.

[0007] Preferably, the inner side of the movable frame is slidably connected to a support frame via a slot, the bottom of the support frame is equipped with a load-bearing mesh plate, and the upper surface of the load-bearing mesh plate is provided with activated carbon blocks.

[0008] Preferably, an auxiliary rod is slidably connected to the inner side of the other end of the movable frame via a slot, and the upper and lower ends of the auxiliary rod are fixedly connected to the flow guide and limiting frame.

[0009] Preferably, a sealing gasket is adhered to the inner surface of the support frame, and a handle is fixedly connected to the outer end of the support frame.

[0010] Preferably, an air inlet pipe is fixedly connected to one end of the housing, a dust filter is installed on the inner side of the air inlet pipe, and an air outlet pipe is fixedly connected to the other end of the housing.

[0011] Preferably, an adjusting screw is fixedly connected to the outside of the housing, and an adjusting sleeve is threadedly connected to the outside of the adjusting screw. A limit plate is rotatably connected to the outside of the adjusting sleeve through a slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The working components provide a functional structure that can change the spacing of activated carbon blocks, adapting to fluctuations in exhaust gas concentration and easily addressing differences in exhaust gas composition. Rotating the rotating sleeve rod causes it to move vertically on the fixed screw, driving the moving frame to change its vertical position, thereby adjusting the distribution of multiple moving frames on the fixed screw and changing the spacing of the activated carbon blocks. Outside air enters the chamber through the air inlet pipe, and large particles are filtered out by the dust filter. The air is then guided by the flow limiting frame, and after being adsorbed by the activated carbon blocks, the purified air is discharged through the air outlet pipe.

[0014] 2. Pull the support frame outward using the handle, and then remove the support frame from the moving frame. The activated carbon blocks inside the support frame can be easily replaced. The load-bearing mesh plate supports the activated carbon blocks while ensuring air circulation. Rotate the adjusting sleeve rod to change the position on the adjusting screw, so that the limiting plate rotates and abuts against the outer end of the support frame to provide pressure and a limiting structure to prevent detachment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 As shown, an easily adjustable activated carbon adsorption box includes a box body 1 and a working assembly 2. The working assembly 2 is installed inside the box body 1. The working assembly 2 includes a flow guide and limiting frame 201 fixedly connected inside the box body 1. A support frame 202 is slidably connected to the inner side of the flow guide and limiting frame 201 through a slot. A fixing screw 203 is fixedly connected to the inner side of the support frame 202. A rotating sleeve 204 is threadedly connected to the surface of the fixing screw 203. A movable frame 205 is rotatably connected to the outer side of the rotating sleeve 204 through a slot. Rotating the rotating sleeve 204 causes the rotating sleeve 204 to be in a fixed position. The screw 203 moves vertically, causing the moving frame 205 to change its vertical position, thereby adjusting the distribution of multiple sets of moving frames 205 on the fixed screw 203 and changing the spacing of the activated carbon blocks 208. In high-concentration waste gas scenarios, the spacing between the activated carbon layers is reduced, increasing the frequency and time of contact between the waste gas and the activated carbon, improving the adsorption efficiency per unit volume, and preventing high-concentration pollutants from penetrating the adsorption layer. In low-concentration waste gas scenarios, the spacing between the layers is increased, reducing airflow resistance and energy consumption (such as fan load), while avoiding "ineffective adsorption" caused by excessive accumulation of activated carbon (no need for excessively dense filling at low concentrations).

[0023] Furthermore, a support frame 206 is slidably connected to the inner side of the movable frame 205 via a slot. A load-bearing mesh plate 207 is installed at the bottom of the support frame 206, and activated carbon blocks 208 are provided on the upper surface of the load-bearing mesh plate 207. The support frame 206 is pulled out laterally from the movable frame 205. The load-bearing mesh plate 207 supports the activated carbon blocks 208 while ensuring air circulation. Multiple sets of activated carbon blocks 208 fill the support frame 206 and can be replaced.

[0024] Furthermore, an auxiliary rod 209 is slidably connected to the inner side of the other end of the movable frame 205 via a slot. The upper and lower ends of the auxiliary rod 209 are fixedly connected to the flow guide and limiting frame 201, and the auxiliary rod 209 provides support and balance for the vertical movement of the movable frame 205.

[0025] Furthermore, a sealing gasket 210 is bonded to the inner surface of the support frame 202, and a handle 211 is fixedly connected to the outer end of the support frame 202. The sealing gasket 210 improves the sealing performance after the support frame 202 is inserted into the box 1, and the handle 211 makes it convenient for the user to exert force.

[0026] Furthermore, an air inlet pipe 3 is fixedly connected to one end of the housing 1, and a dust filter 4 is installed inside the air inlet pipe 3. An air outlet pipe 5 is fixedly connected to the other end of the housing 1. Outside air enters the housing 1 through the air inlet pipe 3 and is filtered by the dust filter 4 to remove large particles. The air is then guided by the air guide and limiting frame 201 and, after being adsorbed by the activated carbon block 208, the purified air is discharged through the air outlet pipe 5.

[0027] Furthermore, an adjusting screw 6 is fixedly connected to the outside of the housing 1, and an adjusting sleeve 7 is threadedly connected to the outside of the adjusting screw 6. A limiting plate 8 is rotatably connected to the outside of the adjusting sleeve 7 through a slot. Rotating the adjusting sleeve 7 changes the position on the adjusting screw 6, so that after the limiting plate 8 rotates, it abuts against the outer end of the support frame 202 to provide pressure and a limiting structure to prevent detachment.

[0028] Working principle: In use, firstly, rotate the rotating sleeve 204 so that it moves vertically on the fixed screw 203, causing the moving frame 205 to change its vertical position, thereby adjusting the distribution of multiple sets of moving frames 205 on the fixed screw 203 and changing the spacing of the activated carbon blocks 208. Secondly, rotate the adjusting sleeve 7 to change its position on the adjusting screw 6, so that the limiting plate 8 rotates and abuts against the outer end of the support frame 202 to provide pressure and a limiting structure to prevent detachment. Thirdly, after the limiting plate 8 is released, the activated carbon blocks can be moved by gripping the handle. 211 Pull the support frame 202 outward, and then remove the support frame 206 from the moving frame 205. The activated carbon block 208 filling the inside of the support frame 206 can be easily replaced. In the fourth step, the air outlet duct 5 is connected to the fan to provide the power for airflow. Outside air enters the box 1 through the air inlet duct 3 and passes through the dust filter 4 to filter large particles of debris. The air is guided by the air guide and limiting frame 201. After being adsorbed by the activated carbon block 208, the purified air is discharged through the air outlet duct 5. This completes the use of an easily adjustable activated carbon adsorption box.
