A q420 galvanized degreasing and iron removal device and its application method

Abstract

The invention discloses a Q420 galvanized degreasing and iron removal device and its use method. The following scheme is proposed now, which includes a cleaning box. Two symmetrical plates are arranged in the cleaning box. As for the moving assembly of the moving plate, two sets of symmetrical cleaning components for preliminary cleaning of the surface of the plate are arranged on the top of the cleaning box, and two sets of symmetrical cleaning components for cleaning the surface of the plate are arranged inside the cleaning box. Scraping assembly for scraping off oil stains and iron powder. The invention has simple structure and convenient operation. The oil stain and iron powder on the surface of the plate can be scraped off through the cooperation of the fixed frame and the sliding plate, and the steel brush passes through the plate before entering the cleaning box The wheel can pre-clean the surface of the plate, which is convenient for degreasing and iron removal of the plate in the later stage. In addition, the steel brush wheel can be replaced regularly to prevent excessive grease and iron powder accumulated in the steel brush wheel from affecting the pre-cleaning of the plate in the later stage.

Description

technical field [0001] The invention relates to the technical field of galvanizing and degreasing, in particular to a Q420 galvanizing, degreasing and iron removal device and a method for using the same. Background technique [0002] Before galvanizing, the cold-rolled galvanized sheet needs to be processed by degreasing, pickling, cleaning and other production processes to remove the residual oil and iron powder on the surface of the sheet, so as to facilitate the later galvanizing. [0003] However, in the prior art, the surface of the workpiece is directly degreased and iron-removed. However, due to the presence of oil stains and iron powder on the surface of the workpiece, the thickness of the iron powder is relatively thick. The grease and iron powder on the surface are cleaned, which will affect the subsequent galvanizing of the workpiece. Therefore, the grease and iron powder on the surface of the workpiece need to be initially cleaned with an iron brush. In addition,...

[0003] However, in the prior art, the surface of the workpiece is directly degreased and iron-removed. However, due to the presence of oil stains and iron powder on the surface of the workpiece, the thickness of the iron powder is relatively thick. The grease and iron powder on the surface are cleaned, which will affect the subsequent galvanizing of the workpiece. Therefore, the grease and iron powder on the surface of the workpiece need to be initially cleaned with an iron brush. In addition, the iron brush cleans the oil and iron powder for a long time, resulting in a large amount of accumulation on the iron brush. Oil stains and iron powder cannot perform preliminary cleaning on subsequent workpieces, so iron brushes need to be replaced regularly
