Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for industrial dust control, and in particular to an adjustable dust collection hood device for industrial plants. Background Technology

[0002] In industrial production processes, machining, building material grinding, and material transfer processes can easily generate a large amount of dust. This dust not only adheres to the surface of production equipment, affecting the equipment's precision and service life, but also permeates the workshop air. When inhaled by workers, it can cause respiratory diseases. In addition, dust accumulation may also cause safety hazards such as fires and explosions. Therefore, it is necessary to use dust collection devices to control dust at dust-generating points.

[0003] Currently, the mainstream dust collection equipment in industrial plants is the fixed dust collection hood. Its structure usually includes a hood body and connecting pipes. During installation, the hood body is directly fixed to a designated position directly above or to the side of the dust-generating equipment by means of welding, bolting, etc. The height of the hood body, the angle of the dust suction port, and the distance from the dust-generating point are all fixed values.

[0004] However, in actual industrial production, there are several scenarios that lead to changes in dust-generating conditions: First, the same dust-generating equipment needs to process workpieces of different specifications, and the difference in workpiece size will cause changes in the height and diffusion range of dust generation; Second, the same equipment needs to switch between different processes, and the dust generation intensity and dust generation point location of different processes are significantly different; Third, some production lines have the need for temporary relocation of dust-generating equipment or adjustment of work positions, and the collection hood needs to be adapted to the new dust generation location.

[0005] Existing fixed dust collection hoods, due to their non-adjustable structure, are difficult to adapt to the aforementioned changes in working conditions: when the dust-generating point moves upward or away from the hood, the distance between the suction port and the dust-generating point increases, resulting in insufficient negative pressure suction coverage, and a large amount of dust will break through the collection range and escape into the workshop; when the dust-generating point moves downward or closer to the hood, the fixed hood is prone to interference with workpieces or operating tools, leading to difficulties in loading and unloading workpieces and reduced work efficiency; in addition, the suction port coverage area of ​​some fixed hoods is fixed, and when the dust-generating point shifts locally, it is impossible to adjust the coverage area accordingly, resulting in local dust concentration exceeding the standard, making it difficult to meet the requirements of the "Occupational Exposure Limits for Hazardous Factors in Industrial Sites" and environmental emission standards.

[0006] Although a few companies have attempted to adjust the position of the dust collection hood by disassembling and reinstalling it, this method requires halting production, consumes significant manpower and resources, and still cannot achieve dynamic adaptation after reinstallation, making it difficult to meet the continuous and flexible production needs of industrial plants. Therefore, developing a dust collection hood device that can flexibly adjust the suction distance according to actual operational needs and adapt to different dust-generating conditions has become the key to overcoming the shortcomings of existing technologies.

There are two push-pull plate assemblies, each of which is installed between the two slide rails and is located on both sides of the slide rails.

[0010] Furthermore, the push-pull panel assembly includes a roller shutter box and a roller shutter panel wound inside the roller shutter box. The two roller shutter boxes are respectively installed on the side walls at opposite ends of the cover.

Once adjusted, the universal bamboo tube 4, due to its structural characteristics, keeps the cover 1 fixed in place. Then, based on the dust generation intensity, workpiece specifications, and other working conditions, the operator pulls the control handle 9 on the roller shutter 7 to extend and retract along the slide rail 5, adjusting the opening of the suction port 2. The indicator clip 11 moves with the roller shutter 7, displaying the adjustment position in real time, while the stop bar 10 prevents the roller shutter 7 from falling off. During adjustment, the sealing gasket 8 on the roller shutter 7 remains sealed to the end face of the suction port 2 of the cover 1 to prevent dust leakage. Dust from the dust-generating point enters the cover 1 through the adjusted suction port 2, is transported to the universal bamboo tube 4 via the connecting pipe 3, and is finally discharged from the workshop, achieving efficient dust collection. The entire process requires no disassembly and reassembly, dynamically adapting to changes in working conditions and meeting the needs of continuous and flexible production.
