Connecting plates 4 are fixed to the outer walls of both the gas collection hood 1 and the filter box 2. A fan 5 is installed inside the gas collection hood 1 to guide the dust and exhaust gas to be discharged quickly. Multi-stage filter plates 8 are installed inside the filter box 2 to filter the dust and exhaust gas step by step. The combined use of sealing films and fastening screws effectively enhances the sealing at the device connections. The sealing frame 3 is designed to prevent dust and exhaust gas from leaking out of gaps, thereby improving the environmental performance of the entire device and reducing pollution to the environment. The inner wall of the sealing frame 3 is covered with a sealing film, and the sealing frame 3 is attached to the connecting plate 4 through the sealing film. The outer end of the sealing frame 3 is provided with a fastening screw, and the sealing frame 3 is sealed and fixed to the connecting plate 4 through the fastening screw. The sealing frame 3 is used to seal the connection of the device to prevent dust and exhaust gas from leaking out. The limit bolts ensure the stability of the connection between the sealing frame 3 and the connecting plate 4, and prevent the two from separating due to vibration or other external forces, thereby ensuring the structural stability of the entire device.

[0020] like Figures 2-4 As shown, the outer end of the connecting plate 4 is symmetrically provided with limiting bolts. The filter box 2 is fixedly connected to the gas collection hood 1 through the connecting plate 4. An alarm light 7 is fixed on the outer wall of the gas collection hood 1. The alarm light 7 is electrically connected to the detection module 6. The detection module 6 is used to detect the concentration of dust and exhaust gas in the production environment.

The interception net 9 can effectively block large particles from entering the fan 5, reduce the burden on the filtration system, and improve the filtration efficiency of the entire device.

[0021] like Figures 3-5 As shown, a drive motor is provided at the outer end of the fan 5. The output end of the fan 5 is fixedly connected to the drive motor. The drive motor provides stable power support for the fan 5, ensuring that the fan 5 can operate continuously and efficiently, thereby ensuring the rapid discharge of dust and exhaust gas and improving the overall processing efficiency of the device. An inspection slot is provided on the inner side of the filter box 2. An observation window 10 is fixed inside the inspection slot.

[0022] Working Principle: During the paint production process, when dust and exhaust gas are generated, the detection module 6 detects the concentration of dust and exhaust gas in the production environment. When the exhaust gas concentration exceeds the set threshold, the alarm light 7 illuminates, and the drive motor is activated to rotate the fan 5. Through its powerful suction, the dust and exhaust gas are quickly discharged from the collection hood 1. When the exhaust gas passes through the connection between the collection hood 1 and the filter box 2, the sealing film laid on the inner wall of the sealing frame 3 ensures that the connecting plate 4 fits tightly, ensuring the sealing of the connection and preventing dust and exhaust gas from leaking due to gaps in the connection. Combined with the fixing effect of the fastening screws, it prevents the sealing frame 3 from shaking and falling off. When the exhaust gas enters the filter box 2, it is filtered step by step by the multi-stage filter plate 8. The dust and exhaust gas first pass through the first stage of the multi-stage filter plate 8, removing the more pollutants. Large particles then enter the medium-efficiency filter layer to remove medium-sized particles; finally, they pass through the high-efficiency filter layer to remove fine particles and harmful gases, thus purifying the exhaust gas step by step to adapt to exhaust gases of different concentrations and compositions. Combined with the interceptor net 9 at the front end of the multi-stage filter screen, large particles are intercepted when the gas enters, reducing the risk of clogging of the multi-stage filter plates 8. After the gas has been filtered for a long time, the operator can check the internal filtration status through the observation window 10 to promptly detect and deal with problems such as clogging or damage of the filter plates, ensuring the efficient operation of the filtration system. After the exhaust gas is discharged after filtration, the rain cover 11 is firmly installed above the outlet under the action of the positioning plate 12 and fastening nails, effectively preventing rainwater from entering the filter box 2 and ensuring the normal operation of the equipment.
