Rapid color change spraying system for surface of sheet metal

Abstract

The invention discloses a rapid color change spraying system for the surface of sheet metal. The rapid color change spraying system comprises a spraying room assembly, a cyclone separator, a filter element recoverer, a powder supply device and an electrical cabinet; the spraying room assembly communicates with the inlet of the cyclone separator through a pipeline, the exhaust port of the cyclone separator is connected with the filter element recoverer, and the powder outlet of the cyclone separator is connected with the powder supply device; and the spraying room assembly, the cyclone separator, the filter element recoverer and the powder supply device are electrically connected with the electrical cabinet. The system has the beneficial effects that powder can be recycled for the second time, the spraying quality is high, the separation effect is better, the filtering efficiency is high, and the energy is saved.

Description

technical field [0001] The invention belongs to the technical field of metal sheet metal surface treatment, and in particular relates to a rapid color-changing spraying system for sheet metal surfaces. Background technique [0002] The high-speed particle flow of molten metal is sprayed on the surface of the substrate to produce a coating material protection technology. The most widely used metal materials for spraying are zinc, aluminum and aluminum-zinc alloys, which are mainly used to protect large structural parts of steel. Electric arc spray guns are commonly used in the machinery industry, which are suitable for metal wire spraying. Flame spray guns are suitable for spraying metal wire as well as cermets and refractory oxides. Plasma arc spray guns and plasma spray welding are suitable for the spraying of various powders. Arc and flame spray guns are used for general anti-corrosion and repair, among them, for spraying zinc and aluminum, which can spray more than 200...

AI Technical Summary

Problems solved by technology

[0003] The existing technology has the following problems: the air inside the spraying room is humid; the ash outlet of the cyclone separator or the dust collection chamber is not well sealed, and the gas is easy to leak in, and the dust collected at the bottom of the cone is rolled up again, which seriously reduces the separation effect; The recycler often does not have a cleaning device, which causes the filter element to be blocked during long-term use, and the filtration efficiency is reduced. The wind blowing in will blow up the filtered powder and affect the filtration; the powder supply barrel is easily left behind in other parts of the powder supply device Different color powder pollution, affecting the spraying effect
