Description

Technical Field

[0001] This utility model relates to the technical field of exhaust gas treatment equipment, and in particular to an exhaust gas treatment device for chemical safety. Background Technology

[0002] In chemical production processes, it is common to carry out processes such as reaction heating, sol spraying, material conveying, and organic solvent evaporation. These processes generate exhaust gases and volatile organic compounds (VOCs). These chemicals can pollute the air and the environment, and harm the health of production operators and those around them. Therefore, it is necessary to treat the exhaust gases to prevent direct emissions.

[0003] However, the filters of traditional chemical safety exhaust gas treatment devices are usually fixed. Although this method can filter the exhaust gas, after long-term use, the particulate matter in the exhaust gas is easy to clog the filter, affecting the working efficiency of the exhaust gas treatment device. Secondly, the exhaust outlet of traditional chemical safety exhaust gas treatment devices lacks an air volume control mechanism, making it difficult for the device to flexibly adapt to downstream devices that further treat the exhaust gas, thus affecting the exhaust gas treatment efficiency.

A fixing post 26 is provided on the side of the mounting frame 22 away from the connector 23. A connector 27 is provided on the side of the cover 24 corresponding to the fixing post 26. A fixing cover 28 is threaded to the top of the fixing post 26. The combination of the fixing post 26, the connector 27 and the fixing cover 28 can ensure the stability of the cover 24 when closed and prevent accidental opening.

[0025] A pair of slide rails 29 are symmetrically arranged on the inner walls of the exhaust box 1 on both sides of the bottom of the mounting hole 21. The slide rails 29 provide a sliding track for the mounting frame 210, ensuring the stability of the mounting frame 210 when it is raised and lowered. The mounting frame 210 is slidably arranged between the two slide rails 29. The mounting frame 210 provides a mounting base for the clamp 211. The clamp 211 is arranged on one side of the mounting frame 210. The clamp 211 is used to cooperate with the clamp 215 to stably clamp the mounting frame 218 and the filter screen 219, making it easy to install and remove the filter screen 219. A sealing gasket 212 is arranged on one side of the clamp 211 to ensure the sealing between the clamp 211 and the mounting frame 218. A pair of mounting plates 213 are arranged on the inner wall of the mounting frame 210 away from the clamp 211. A pair of precision springs 214 are provided between the two mounting plates 213. The precision springs 214 provide a restoring force for the clamp 215, ensuring that the clamps 211 and 215 stably clamp the mounting frame 218. The clamp 215 is provided on one side of the two precision springs 214. The clamp 215 can move and adjust its position between the two mounting plates 213 to accommodate different sizes of mounting frames 218 and filters 219. A pair of slide rails 216 are symmetrically provided on the inner walls of the upper and lower sides of the mounting frame 210. The clamp 215 is slidably mounted on the slide rails 216. The slide rails 216 can ensure the stability of the clamp 215 when it moves. A sealing gasket 217 is provided on one side of the clamp 215. The sealing gasket 217 can ensure the sealing between the clamp 215 and the mounting frame 218.

[0026] The clamp 1 211 and clamp 2 215 are provided with mounting frame 3 218. Mounting frame 3 218 provides a mounting base for filter screen 219. Filter screen 219 is installed inside mounting frame 3 218. Filter screen 219 filters the exhaust gas to ensure that the exhaust gas meets the emission requirements. Sealing strip 2 220 is provided on the back of mounting frame 3 218. Sealing strip 2 220 ensures the sealing between mounting frame 3 218 and mounting frame 2 210 to prevent exhaust gas from leaking from gaps.

[0027] Mounting frame 210 has a mounting plate 221 on one side. A pair of lifting guide columns 222 are symmetrically arranged on both sides of the bottom of mounting plate 221. A telescopic cylinder 223 is arranged on the bottom surface of the exhaust box 1 at the position corresponding to mounting plate 221. The top of the telescopic rod of telescopic cylinder 223 is connected to the bottom of mounting plate 221. The telescopic rod of telescopic cylinder 223 extends and retracts, driving mounting plate 221 to rise and fall. Mounting plate 221 transmits power to mounting frame 210, thereby enabling mounting frame 210 to rise and fall along slide rail 29. Guide column sleeves 224 are arranged on both sides of telescopic cylinder 223 at the positions corresponding to lifting guide columns 222. The combination of lifting guide columns 222 and guide column sleeves 224 can ensure the stability of mounting plate 221 when it rises and falls.

[0028] The exhaust opening adjustment assembly 3 includes a telescopic cylinder 31 located on one side of the top of the exhaust box 1. The telescopic rod of the telescopic cylinder 31 extends through the top of the exhaust box 1. The telescopic cylinder 31 adjusts the height of the gate 32 by means of the telescopic rod, thereby controlling the exhaust volume of the filtered exhaust gas. A sealing bearing 33 is provided on the top surface of the exhaust box 1 at the position corresponding to the telescopic rod of the telescopic cylinder 31. The sealing bearing 33 ensures the sealing between the telescopic rod of the telescopic cylinder 31 and the exhaust box 1 to prevent exhaust gas leakage. A gate 32 is provided at the bottom of the telescopic rod of the telescopic cylinder 31. The gate 32 is located on one side of the exhaust port 12. The opening is controlled by the telescopic cylinder 31 to adjust the exhaust volume.

[0029] An air inlet 11 is provided on one side of the exhaust box 1. The air inlet 11 is the entrance for exhaust gas to enter the exhaust box 1. An exhaust outlet 12 is provided on the side of the exhaust box 1 away from the air inlet 11. The exhaust outlet 12 is the outlet for the filtered exhaust gas to exit the exhaust box 1.

[0030] During use, the user can introduce exhaust gas into the exhaust box 1 through the air inlet 11. The filter screen 219 filters the exhaust gas, and the filtered exhaust gas is discharged from the exhaust box 1 through the exhaust port 12. After the filter screen 219 has been used for a period of time, impurities will adhere to the surface of the filter screen 219 and cause blockage. The user can first stop the exhaust device, then loosen and remove the fixing cover 28, open the protective cover 24, and then start the telescopic cylinder 223. The telescopic rod of the telescopic cylinder 223 extends to raise the mounting plate 221. The lifting guide column 222 and the guide sleeve 224... The combination ensures the stability of the mounting plate 221 during lifting, thereby driving the mounting frame 210 to rise steadily along the slide rail 29. Then, the user can push the clamp 215 to move it away from the clamp 211. The clamp 215 moves along the slide rail 216 and squeezes the precision spring 214, thereby releasing the mounting frame 218 and the filter screen 219. The user can remove the mounting frame 218 and the filter screen 219 for cleaning or replacement. When the external force is removed, the precision spring 214 can push the clamp 215 to reset.

[0031] When reinstalling mounting frame 3 218 and filter screen 219, the user can first press one side of mounting frame 3 218 against clamp 1 211, and then push clamp 2 215. Clamp 2 215 compresses precision spring 214, allowing mounting frame 3 218 to fit against mounting frame 2 210. After installation, the user can release clamp 2 215. Precision spring 214 provides a restoring force to clamp 2 215. Precision spring 214 is a spring with a very small wire diameter, strong stability, and stable force value, thus enabling clamp 1 211 and clamp 2 215 to stably clamp mounting frame 3 218 and filter screen 219. The combination of sealing gasket 1 212 on one side of clamp 1 211, sealing gasket 2 217 on one side of clamp 2 215, and sealing strip 2 220 on the back of mounting frame 3 218 ensures proper filtration of exhaust gas. The system ensures airtightness, preventing exhaust gas from passing through the gaps between mounting frame 210, mounting frame 318, clamp 1 211, and clamp 215. Then, the telescopic rod of telescopic cylinder 1 223 retracts, causing mounting frame 210 to descend back into the exhaust box 1. The protective cover 24 is then closed, allowing connector 27 on one side of the protective cover 24 to pass through the fixing post 26. The stability of the protective cover 24 when closed is ensured by tightening the fixing cover 28. The sealing strip 25 at the bottom of the protective cover 24 effectively ensures the airtightness and safety of the exhaust box 1 in a non-maintenance state. When the user needs to adjust the exhaust opening, the height of the gate 32 can be adjusted by telescopic cylinder 2 31 to control the exhaust volume. At the same time, the sealing bearing 33 ensures the airtightness between the telescopic cylinder 2 31 and the exhaust box 1.
