Fast color changing and spraying equipment for metal surfaces

Abstract

The invention discloses fast color changing and spraying equipment for metal surfaces. The equipment includes a coating device, a cyclone separation device, a filtering core recovery device, a powdersupply device and an electrical device. The spraying device includes a worktable, a spraying chamber, a hollow belt, an exhaust fan and a material storage box; the spraying chamber is formed in the upper portion of the worktable, vertical sliding tracks symmetric to each other are arranged on the inner wall of the spraying chamber, and limiting blocks symmetric to each other are arranged on the upper and lower sides of each vertical sliding track. The leakproofness of the spraying chamber of the spraying device is high, since the spraying device is communicated with the exterior through only one overhaul door, coloring particles can be effectively prevented from diffusing to the exterior air, and even if a small part of particles tend to diffuse outwards from gaps, the particles can be sucked by the exhaust fan. The exhaust fan can collect the coloring particles sprayed around a metal block into a material storage groove, environmental pollution is avoided on the one hand, recycle of resources can be achieved on the other hand, and the cost of raw materials for spraying is saved.

Description

technical field [0001] The invention belongs to the technical field of metal spraying, in particular to a rapid color-changing spraying equipment for 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 kg per hour; Using high-energy pla...

AI Technical Summary

Problems solved by technology

[0003] The existing technology has the following problems: 1. During the spraying process of metal spraying equipment, some colored particles may diffuse in the air, which affects the surrounding environmental quality, endangers people's health, and leads to waste of resources; 2. Most of the cyclone separation equipment It is filtered by a filter device, but the existing filter device has a simple structure and a single function, and needs to be disassembled and cleaned manually, which increases the labor intensity of the staff and cannot meet the modernization requirements; The service life of the filter element is short, and re-use will affect the filtration efficiency, which will cause damage to the entire system; 4. The adjustment of the powder supply center is troublesome, and it is inconvenient to fix it with the ground; 5. The electrical equipment for color change on the metal surface cannot dissipate heat in time when in use , long-term use will cause overheating and combustion, and at the same time cannot prevent static electricity, causing inconvenience in use
