Device and method for coating normal-temperature metal ion flash smelting surface

Abstract

The invention relates to a device and method for coating a normal-temperature metal ion flash smelting surface. The device comprises a power supply system, a control system, a high-speed transmission line system, a high-speed electric arc system and a compressed air supply system, wherein the control system is a microcomputer control part of the surface coating device, connected with the power supply system and used for integrating work operation control of the surface coating device; the high-speed transmission line system is connected with the control system and used for conveying a metal ion wire rod; the high-frequency electric arc system is connected with the high-speed transmission line system and used for conveying metal ion wire rod high-frequency electric arc into one or more mixed ion liquefied metal objects; and the compressed air supply system is connected with the high-frequency electric arc system and used for conveying the ion liquefied metal object to a smelting spray gun in a flash manner and spraying the ion liquefied metal object subjected to effective adjustment to the surface of a coated object in a flash manner. The device has a compact structure through finematching of all assemblies and really achieves the effects of environment protection, energy saving, consumption reduction, emission reduction and the like; and the utilization rate of equipment energy sources is very high and generally reaches 85 percent by applying a normal temperature technology.

Description

technical field [0001] The invention relates to a surface coating method and device, in particular to a normal temperature metal ion flash melting surface coating method and device. Background technique [0002] Traditional metal electroless plating and spraying technology requires a lot of investment to build a production line. The construction of a plant covers a large area, including acid pools, alkali pools, electroplating tanks, grinding and polishing and environmental protection treatment and other major equipment, which will generate waste water, waste gas, noise and solids. Waste and other toxic and harmful substances (mainly chemical raw materials) affect the health of employees and pollute the ecological environment. Pretreatment processes such as high temperature pickling, alkali washing or chemical heat treatment are usually required. Time-consuming, labor-intensive, material-consuming, water-consuming, electricity-consuming, and inefficient. It is not suitable...
