Description

Technical Field

[0001] The utility model relates to the field of steel plate pickling, in particular to a brush roller for steel plate pickling. Background Art

[0002] Steel pickling means to make the strip steel have a clean and active surface to ensure the surface quality of the produced steel. The iron oxide scale on the surface of steel is an oxide that is insoluble in water. When they are immersed in acid solution, these oxides will undergo a series of chemical reactions with the acid to remove the iron oxide scale on the surface.

[0003] After searching, a steel plate multi-directional pickling equipment with announcement number CN220413532U includes a pickling tank, a discharge pipe is arranged at the bottom of the pickling tank, and also includes: a support table, a fixed plate of which is arranged on one side of the pickling tank; a winding mechanism, the winding mechanism for winding the steel plate is located at the upper end of the support table; a liquid collecting tank, which is arranged on the side of the winding mechanism close to the pickling tank;

[0004] Based on the above patent, uniform pickling is achieved by immersing the steel plate in a pickling tank, but the effect is general, and the iron oxide scale on the surface of the steel plate cannot be cleaned up. Through the cooperation of the pickling component, the pickling tank and the guide roller four, the guide roller four is lower than the water level line of the pickling liquid, so that the steel plate that has been pickled once can be immersed again while the iron oxide scale on the surface of the steel plate that has not been pickled off can be cleaned up by the bristles under the guidance of the guide roller four, so that the surface of the steel plate is smoother. However, the brush roller on the pickling device will accumulate more impurities after long-term use. If it is not cleaned, it will affect the cleaning quality of the steel plate. At the same time, when the bristles on the brush roller are damaged, the bristles cannot be replaced individually, and the brush roller can only be replaced as a whole, thereby increasing the replacement cost.
