Description
Technical Field
The invention relates to the field of hot dipping zinc, in particular to automatic hot dipping zinc production line equipment and process of a radiator for a high-voltage transformer.
Background
The traditional process flow of hot dip galvanizing mainly comprises the following steps: degreasing, namely removing lubricating oil attached between the part and the grinding tool during stamping; washing, namely washing the degreasing agent on the surface of the radiator in a washing tank; acid washing, namely removing iron oxides on the surface of the radiator in an acid washing tank; washing with water, namely washing off acid liquor on the surface of the radiator in a washing tank; dipping the plating assistant liquid to keep the radiator active before zinc dipping to avoid secondary oxidation and enhance the combination of the plating layer and the matrix; drying and preheating, namely drying the moisture on the surface of the radiator and simultaneously increasing the temperature of the radiator; hot dip galvanizing, so that a zinc layer is attached to the surface of the radiator; finishing, removing residual zinc and zinc drops on the edge of the radiator after zinc dipping; cooling to make the radiator quickly cooled to room temperature; passivation, improvement of atmospheric corrosion resistance of the surface of the radiator, reduction or extension of white embroidery appearance time and maintenance of good appearance of a plating layer; rinsing, namely washing away residual passivation solution on the surface of the radiator; drying to make the liquid on the surface of the radiator disperse; and (5) checking whether the appearance of the plating layer is qualified or not and whether the thickness of the plating layer meets the technical requirements or not.
In the traditional process, after the radiator leaves the zinc immersion liquid level, residual zinc and zinc drops on the surface of the radiator are scraped off manually by using a scraper, and the liquid outlet speed of the radiator leaving the zinc immersion liquid level is controlled by controlling the crane lifting speed, so that manpower is consumed, the efficiency is low, the body health is influenced by the high-temperature and severe manual operation environment on the zinc pot side, and potential safety hazards exist. After the radiator is immersed in the zinc liquid, zinc ash generated by contact reaction between the surface of the radiator and the zinc liquid cannot be quickly separated from the surface of the radiator, and the zinc ash on the surface of the zinc immersion liquid after zinc immersion is easy to generate black spots and grey specks on the surface of the radiator, so that the appearance and the quality of the radiator are affected. Therefore, attempts have been made to improve the above-mentioned technical solutions. Chinese patent document CN96205860.2 "a hot-dip zinc scraping device" proposes an impact support composed of a movable support, a fixed base and an elastic connecting component, which is used to remove the residual zinc on the heat sink. However, the technical solution still has the disadvantages that only the heat sinks with smaller size can be adapted, and the mutual collision of the heat sinks can damage the heat sinks, so that the surfaces of the heat sinks are provided with concave traces.
In the traditional process, a large amount of smoke is generated in the process of carrying out hot dip galvanizing on the radiator, and simultaneously, water vapor generated in the reaction process is accompanied. The substances generated in the reaction are filtered once by a dust removal filtering and purifying device and then are discharged into the atmosphere. After the dust removal filtration and purification equipment filters and purifies the smoke once, the smoke which is not filtered and purified completely is still discharged into the air, and certain temperature is carried along, so that the environment for people to live is polluted, the health of people is affected, and meanwhile, the temperature carried by the gas is not fully utilized, so that the energy waste is caused.
In the traditional process, scum generated in the zinc dipping process is stored on the surface of zinc liquid, mainly zinc-iron alloy with extremely poor liquidity is formed when the iron content dissolved in the zinc liquid exceeds the solubility at the temperature, the zinc scum floats on the surface of the zinc liquid, a radiator is easy to flow and hang on the surface and the edge of the radiator after zinc liquid is discharged, the appearance and the quality of a product are seriously affected, before and after the radiator enters and exits the zinc liquid, a scraper is needed to scrape the scum on the liquid surface manually, the situation that the scum is not left on the liquid surface of the zinc dipping when the radiator discharges the zinc liquid is ensured, the radiator can not hang the zinc scum, the process is time-consuming and labor-consuming, the scum is scraped by a high-temperature zinc pot manually, and potential safety hazards also exist under severe operation.
