Description

Technical Field

[0001] This utility model relates to the field of hot rolling production technology, and in particular to a micro-mist dust removal device for steel strip pressing and rolling. Background Technology

[0002] During the rolling process, iron oxide powder, water vapor generated during cooling, and flue gas produced by the combustion of lubricating oil are generated. Therefore, a large amount of white water mist (more when the ambient temperature is low) and yellow smoke are often seen at the entrance and exit of the rolling mill. Such water mist and dust are very harmful. Water mist condenses on the equipment, causing equipment corrosion and failure. The dust particles are very fine and easily deposit deep in the lungs, posing a great threat to health. Dust blocks accumulated on the stand fall into the strip and cause surface quality problems. Therefore, a micro-mist dust removal device for steel strip rolling is provided. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a micro-mist dust removal device for steel strip rolling. By reusing wastewater, the water is atomized and sprayed out, replacing the original water spraying. This not only improves the dust removal effect but also significantly reduces the amount of water sprayed, greatly reducing the temperature drop on the steel plate surface. It also effectively reduces dust accumulation in the rolling mill equipment, reduces the phenomenon of dust blocks falling from the frame and pressing into the steel plate, improves the surface quality of the steel plate, reduces the wear of fine dust on bearings and other mechanical moving parts, and lowers the concentration of dust particles. This extends the service life of on-site valve groups and electrical components, extends the service life of equipment, reduces the equipment failure rate, and overcomes the shortcomings of existing technologies.

Flanges are welded to the lower ends of the vertical sections on both sides of the U-shaped frame, and a controller is installed on one side of the U-shaped frame.

[0006] As a further embodiment of this utility model: the filtration module includes a filter box, a secondary return water pipe is fixed on one side of the top of the filter box, a solenoid valve is installed on the secondary return water pipe, and a filter element is placed inside the filter box.
