Abstract
Description
A dust removal device for ventilation equipment Technical Field
[0001] This utility model relates to the field of ventilation equipment, and in particular to a dust removal device for ventilation equipment. Background Technology
[0002] In industrial production and other places with high air quality requirements, ventilation equipment plays a key role in maintaining air circulation and ensuring the comfort and safety of the working environment. However, during the ventilation process, the air is often mixed with a large amount of dust, particulate matter and other pollutants. These pollutants not only affect indoor air quality and endanger the health of workers, but may also damage the ventilation equipment itself, reduce the service life and operating efficiency of the equipment. Therefore, dust removal is necessary during ventilation.
[0003] Currently, the main dust removal method for ventilation equipment is to use filter plates. However, filter plates are easily clogged by dust during dust removal, requiring regular cleaning or replacement, which results in high maintenance costs and inconvenience to dust removal work. Therefore, we propose a dust removal device for ventilation equipment to solve the above problems. Summary of the Invention
[0004] The purpose of this invention is to provide a dust removal device for ventilation equipment to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A dust removal device for ventilation equipment includes a ventilation duct, a dust removal hood fixedly connected to the top end of the ventilation duct, a filter hood fixedly connected to the top end of the dust removal hood, an activated carbon adsorption plate fixedly installed on the inner wall of the filter hood, a filter plate fixedly installed on the inner wall of the dust removal hood, a through hole opened on the bottom surface of the filter plate, multiple fixing plates fixedly connected to the inner wall of the dust removal hood, a drive motor fixedly connected to one side of each fixing plate that is close to each other, a drive shaft fixedly installed at the output end of the drive motor, multiple cleaning brushes fixedly connected to the outer surface of the drive shaft, the upper surface of each cleaning brush contacting the bottom surface of the filter plate, a dust removal pipe fixedly connected to the bottom end of the ventilation duct, and an electric butterfly valve fixedly connected to the outer surface of the dust removal pipe.
[0007] In a further embodiment, an air inlet pipe is fixedly connected to the outer surface of the ventilation pipe, and an air inlet flange is fixedly connected to the left end of the air inlet pipe.
[0008] In a further embodiment, an annular plate is fixedly connected to the top of the filter cover, a connecting cover is fixedly connected to the upper surface of the annular plate, and a connecting flange is fixedly connected to the top of the connecting cover.
[0009] In a further embodiment, the bottom surface of the filter cover is provided with a flow port, which is located below the activated carbon adsorption plate.
[0010] In a further embodiment, a dust collection fan is fixedly installed on the inner wall of the ventilation duct, and the dust collection fan is located above the dust removal duct.
[0011] In a further embodiment, a connecting block is fixedly connected to the outer surface of the ventilation duct, and a controller is fixedly installed on the right side of the connecting block.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention effectively intercepts larger dust particles through the filter plate inside the dust collector hood, ensuring initial filtration. The activated carbon adsorption plate effectively adsorbs harmful gases and some fine dust, improving air quality during ventilation. By opening the electric butterfly valve and using the drive motor to rotate the cleaning brush, the dust intercepted on the bottom surface of the filter plate is brushed off and automatically discharged through the dust removal pipe, achieving a self-cleaning effect for the dust collection equipment. This eliminates the need for frequent manual disassembly and cleaning, reducing maintenance costs and labor intensity, while also ensuring the continuous and stable operation of the equipment.

[0022] Please refer to Figures 1-4. In this utility model, a dust removal device for ventilation equipment includes a ventilation pipe 1. A dust removal hood 3 is fixedly connected to the top end of the ventilation pipe 1. A filter hood 4 is fixedly connected to the top end of the dust removal hood 3. An activated carbon adsorption plate 6 is fixedly installed on the inner wall of the filter hood 4. A filter plate 9 is fixedly installed on the inner wall of the dust removal hood 3. A through hole 10 is opened on the bottom surface of the filter plate 9. Multiple fixing plates 8 are fixedly connected to the inner wall of the dust removal hood 3. A drive motor 7 is fixedly connected to one side of each fixing plate 8 that is close to each other. A drive shaft 20 is fixedly installed at the output end of the motor 7. Multiple cleaning brushes 11 are fixedly connected to the outer surface of the drive shaft 20. The upper surface of each cleaning brush 11 is in contact with the bottom surface of the filter plate 9. A dust removal pipe 13 is fixedly connected to the bottom end of the ventilation pipe 1. An electric butterfly valve 12 is fixedly connected to the outer surface of the dust removal pipe 13. By driving the motor 7 to rotate the cleaning brushes 11, the dust intercepted on the bottom surface of the filter plate 9 can be brushed off and automatically discharged through the dust removal pipe 13, thus achieving the effect of self-cleaning of the dust removal equipment.
[0023] In a further embodiment, an air inlet pipe 2 is fixedly connected to the outer surface of the ventilation pipe 1, and an air inlet flange 16 is fixedly connected to the left end of the air inlet pipe 2. An annular plate 5 is fixedly connected to the top of the filter cover 4, and a connecting cover 18 is fixedly connected to the upper surface of the annular plate 5. A connecting flange 17 is fixedly connected to the top of the connecting cover 18. A flow port 19 is opened on the bottom surface of the filter cover 4. The flow port 19 is located below the activated carbon adsorption plate 6. Through the setting of the air inlet pipe 2 and the air inlet flange 16, it can be connected and installed with ventilation equipment. The setting of the annular plate 5, the connecting cover 18 and the connecting flange 17 facilitates connection with ventilation ducts and improves the flexibility of connection.
[0024] In a further embodiment, a dust collection fan 21 is fixedly installed on the inner wall of the ventilation duct 1. The dust collection fan 21 is located above the dust removal duct 13. A connecting block 14 is fixedly connected to the outer surface of the ventilation duct 1. A controller 15 is fixedly installed on the right side of the connecting block 14. By setting up the dust collection fan 21, the dust brushed off can be extracted and discharged, which will better assist in dust cleaning. The controller 15 plays a core control role. It can control the start and stop of the drive motor 7, the speed, and the opening and closing status of the electric butterfly valve 12 according to preset parameters or real-time monitored air quality data, to ensure that the dust removal device operates efficiently and stably and meets the ventilation and dust removal needs under different working conditions.
[0025] The working principle of this utility model is as follows: First, it is connected to other ventilation equipment through the air inlet flange 16. Dust-laden air flows into the interior of the ventilation pipe 1 through the air inlet pipe 2. When the dust-laden air passes through the filter plate 9, larger dust particles are intercepted. The air that has undergone preliminary filtration continues to rise and enters the filter cover 4. The activated carbon adsorption plate 6 further removes odors, harmful gases and some fine dust from the air. When cleaning the dust on the surface of the filter plate 9, the electric butterfly valve 12 is opened, and the drive motor 7 drives multiple cleaning brushes 11 to rotate. By using the cleaning brushes 11 to contact the bottom surface of the filter plate 9, the dust intercepted on the filter plate 9 can be brushed off. Then, it is extracted by the dust collection fan 21 and discharged through the dust removal pipe 13.
