Q420 zinc plating degreasing and iron removing device and using method thereof

Abstract

The invention discloses a Q420 zinc plating degreasing and iron removing device and a using method thereof. The Q420 zinc plating degreasing and iron removing device provides the following scheme that the Q420 zinc plating degreasing and iron removing device comprises a cleaning box, two symmetrical plates are arranged in the cleaning box, a moving assembly used for moving the plates is arranged above the cleaning box, the top of the cleaning box is provided with two sets of symmetrical cleaning assemblies used for conducting preliminary cleaning on the surface layers of the plates, and the interior of the cleaning box is provided with two sets of symmetrical scraping assemblies used for conducting oil stain and iron powder scraping on the surface layers of the plates. The Q420 zinc plating degreasing and iron removing device is simple in structure and convenient to operate, through mutual cooperation of a fixed frame and a sliding plate, oil stains and iron powder on the surface layers of the plates can be scraped away, the surface layers of the plates can be cleaned in advance through a steel brush wheel before the plates enter the cleaning box, degreasing and iron removal can be conveniently conducted on the plates in the later period, in addition, the steel brush wheel can be replaced regularly, and the influence of excessive grease and iron powder accumulated in the steel brush wheel on later-stage pre-cleaning of the plates is prevented.

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
