Color steel plate cleaning and magnetism removing device

Abstract

The invention provides a color steel plate cleaning and magnetism removing device. A cleaning unit and a drying unit are arranged on the upper portion of a workbench. A material putting roller is arranged in the upstream position of the cleaning unit, and a material collecting roller is located in the downstream position of the drying unit. Three layers of tension rollers are arranged in a cleaning tank, the lower-layer roller is arranged in the position, close to the bottom, of the cleaning tank, and a washing device is arranged at the bottom of the cleaning tank. The drying unit comprises electric heating rollers and a drying case. A fixed pole in a magnetism removing unit is arranged in the middle of a case body, a magnetic pole is connected with the fixed pole in a sleeving mode, a water inlet pipe communicates with the bottom of the cleaning tank and the case body, and a water outlet pipe is vertically arranged on the inner side of the case body. A temperature control device is reasonable in design, and can take the temperature adjusting effect on the cleaning device, so that a galvanized steel plate can be cleaned under a preferential temperature, washing liquid can be recycled, and environmental protection cost of the equipment is saved.

Description

technical field [0001] The invention belongs to the technical field of plate cleaning equipment, and in particular relates to a color steel plate cleaning and demagnetizing device. Background technique [0002] Cleaning is an essential and important process in the production process of galvanized metal materials. Whether it is pre-plating cleaning or post-plating cleaning, it will affect the quality of metal plating and chemical coating of galvanized steel sheets. The temperature of the lotion should be controlled. If the temperature is too high, the passivation film will be easily broken, and the film of the parts after passivation will be thin and light in color, and the corrosion resistance will be poor. If the temperature is too low, it will not be conducive to thoroughly cleaning the parts. At present, the structure of cleaning machines on the market is relatively complicated, and the operation is inconvenient. Due to the unreasonable design structure, the cleaning qual...

AI Technical Summary

Problems solved by technology

The temperature of the washing liquid should be controlled. If the temperature is too high, the passivation film will be easily broken, and the film of the parts after passivation is thin and light in color, and the corrosion resistance is poor; if the temperature is too low, it is not conducive to cleaning the parts thoroughly.

At present, the structure of cleaning machines on the market is relatively complicated, and the operation is inconvenient. Due to the unreasonable design structure, the cleaning quality is not high, and it is easy to leave scratches on the surface of the sheet or deform the sheet, which will affect the quality and service life of the final galvanized steel sheet. Not conducive to market competition

At the same time, the galvanized steel sheet washing device in the prior art does not have the function of not only containing a temperature control device but also being able to fully clean the galvanized steel sheet
