Screening device for rolling slurry production in medium-wide strip steel reversible rolling mill

By designing a screening device for the production of rolling fluid in a reversible rolling mill for medium-wide strip steel, a drive unit is used to drive a coupling to rotate a sludge scraper to remove impurities. This solves the problem of filter screen clogging caused by impurities in the rolling oil, improves the cleaning efficiency and stability of the filtration equipment, and reduces maintenance costs.

Abstract

This utility model relates to the field of sieving technology for rolling mill slurry, and more particularly to a sieving device for producing rolling mill slurry in reversible medium-wide strip steel. It includes a filter assembly, a cleaning assembly, and a sieving tube. The filter assembly houses the sieving tube, and the sieving tube houses the cleaning assembly. This utility model injects the rolling mill slurry from the lower opening of the sieving tube. The slurry then passes through the sieve holes of the sieving tube into the filter tank, and finally is discharged and collected from the discharge pipe. Because the sludge scraper contacts the inner wall of the sieving tube, when the driver drives the coupling to rotate the sludge scraper, the scraper scrapes off the sludge and impurities adhering to the inner wall of the sieving tube, thereby improving the cleaning efficiency of the sieving tube and extending its service life.
