Galvanized layer surface treatment device for galvanized sheet

The invention relates to the field of galvanized sheet surface cleaning, in particular to a galvanized sheet galvanized layer surface treatment device which comprises a conveying unit and a cleaning unit, and the cleaning unit is erected above the conveying unit. According to the surface treatment device for the galvanized layer of the galvanized plate, the galvanized plate is limited in the circumferential direction by adjusting the positions of the limiting blocks and the limiting rolling wheels, it is guaranteed that the galvanized plate in the conveying state is not clamped or deviated when making contact with the cleaning unit, and the cleaning effect of the surface of the galvanized plate is better; the side baffles and the flow guide plates are connected with the portal frame in an inserted mode, the side baffles and the flow guide plates can be rapidly taken down through the connection mode, impurities and sewage generated after cleaning are removed, and blockage caused when the sewage flows to the st
