Technical Field

[0001] This utility model relates to the field of compound treatment, specifically to a device for treating volatile organic compounds. Background Technology

[0002] The development of volatile organic compound (VOCs) treatment equipment is primarily driven by the threat posed by industrial emissions to the environment and human health.

[0003] Existing volatile organic compound (VOC) treatment equipment sometimes includes filters for initial filtration of VOCs. However, some filters are directly bolted in place, making removal difficult due to the need for tools, time-consuming process, and the tendency for bolts to rust and age. Therefore, this paper proposes a VOC treatment device to address these problems. Utility Model Content

[0023] 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.

[0024] Example:

[0025] Please see Figure 1 - Figure 5 This embodiment of a device for treating volatile organic compounds includes a working box 1. An air inlet pipe 2 and an air outlet pipe 9 are fixedly connected to the left and right sides of the working box 1, respectively. Multiple activated carbon adsorption plates 8 are movably inserted into the inside of the working box 1. A filter screen 3 is movably inserted into the inside of the air inlet pipe 2. Two insert blocks 4 are slidably connected to the inside of the air inlet pipe 2. Two slots adapted to the insert blocks 4 are opened on the inside of the filter screen 3. The outer sides of the two insert blocks 4 are movably inserted into the inner side of the corresponding slots. A threaded block 6 is threadedly connected to the outside of the air inlet pipe 2. The inner side of the threaded block 6 is movably abutted against the outer side of the two insert blocks 4. Two small springs 5 ​​are fixedly connected to the outside of the air inlet pipe 2. The other ends of the two small springs 5 ​​are fixedly connected to one side of the corresponding insert block 4.

[0026] When the user needs to clean the filter screen 3, simply push the first block 7 upwards and then rotate the threaded block 6. At this time, the inner side of the threaded block 6 will no longer be in contact with the outer side of the insert block 4, and the user can remove the filter screen 3. At this time, the insert block 4 will be squeezed and begin to compress the small spring 5, and then the user can remove it smoothly for cleaning.

[0027] A block 7 is slidably connected to one side of the work box 1, and two springs are fixedly connected to one side of the block 7. The other ends of the two springs are fixedly connected to one side of the work box 1. The outer side of the threaded block 6 has multiple slots that are compatible with the block 7. The outer side of the block 7 is movably inserted into the inner side of the corresponding slot. Two rotating doors 10 are rotatably connected to one side of the work box 1. A connecting block 11 is fixedly connected to one side of each rotating door 10. A shell 12 is fixedly connected to the top of the work box 1. A handwheel 13 is rotatably connected to the inner wall of the top of the shell 12. A rotating frame 16 is fixedly connected to the bottom of the handwheel 13. Two connecting rods 17 are rotatably connected to the inner side of the rotating frame 16. The other ends of the two connecting rods 17 are rotatably connected to a moving block 18. The outer sides of the two moving blocks 18 are movably inserted into the inner side of the corresponding connecting block 11. This allows the two rotating doors 10 to be easily fixed.

[0028] A fixed block 14 is fixedly connected to the top of the outer casing 12, and a gravity block 15 is slidably connected to the inner side of the fixed block 14. The top of the handwheel 13 has multiple circular grooves that are adapted to the gravity block 15. The outer side of the gravity block 15 is movably inserted into the inner side of the corresponding circular groove. The same guide strip is fixedly connected to the inner walls of the left and right sides of the outer casing 12. The outer side of the guide strip is slidably connected to the inner side of the two moving blocks 18, so that the moving blocks 18 can move horizontally stably.

[0029] An air collection hood is fixedly connected to the outside of the air inlet pipe 2, and a control valve is installed on the outside of the air outlet pipe 9. Glass windows are fixedly connected to one side of each of the two rotary doors 10, so that users can observe the internal condition of the device and replace the new activated carbon adsorption plates in a timely manner.

[0030] The working principle of the above embodiments is as follows:

[0031] In use, the exhaust gas pipe is connected to the gas collection hood. Larger impurities in the exhaust gas are filtered by filter screen 3. The gas then enters the device through the inlet pipe 2. VOCs molecules pass through the activated carbon adsorption plate 8, which adsorbs the VOCs molecules. After multiple layers of activated carbon adsorption plates 8 adsorb the VOCs molecules, the user can open the control valve to discharge clean gas from the outlet pipe 9. When the user needs to clean the filter screen 3, simply push block 7 upwards and then rotate the threaded block 6. At this point, the inner side of the threaded block 6 is no longer in contact with the outer side of the insert block 4, and the user can remove the filter screen 3. At this time, the insert 4 is squeezed and begins to compress the small spring 5, which can then be easily removed by the user for cleaning. When fixing the revolving door 10, the user first lifts the gravity block 15 and turns the handwheel 13, causing the rotating frame 16 to start rotating. Then the connecting rod 17 starts to rotate, and then the moving block 18 starts to move horizontally. The moving block 18 can then be directly inserted into the inside of the connecting block 11. At this time, the user no longer needs to lift the gravity block 15. Under the action of gravity, the gravity block 15 is inserted into the corresponding position inside the handwheel 13, thus completing the fixing work. A sealing ring is provided at the closing point of the revolving door 10 and the work box 1, which can improve the airtightness of the device.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
