Apparatus integrating surface vacuum spraying of workpiece, paint solidifying and waste paint and solvent recycling, and process thereof

Abstract

The invention discloses an apparatus integrating surface vacuum spraying of a work piece, paint solidifying and waste paint and solvent recycling, and a process thereof. The apparatus comprises a paint spraying and paint solidifying integrated vacuum chamber, a waste paint and solvent filtration device, an air compression device, a spray gun oil supply system and a spray gun air supply system. The paint spraying and paint solidifying integrated vacuum chamber is internally provided with a spray gun, a workpiece hanger turntable, a heating device, a temperature detection device, an air inlet pipe, an exhaust pipe and a vacuum chamber revolving door. The process comprises: a, a vacuum paint spraying process, b, a paint solidifying process, and c, a waste paint and solvent filtration process. The atomization effect of the paint ejected in the vacuum environment is enhanced, the surface paint spraying decoration of the product and the paint solidifying are smoother and more uniform, and water spots, gas spots or paint spots cannot be generated. The recycle of the waste gas, the waste paint and the solvent can be realized so that the environment cannot be polluted. In the operation process, the invention saves two thirds of the paint and reduces 50% of the production cost.

Description

technical field [0001] The invention relates to equipment and technology for workpiece surface spraying, paint curing, waste paint and solvent recovery, in particular to a workpiece surface vacuum spraying, paint curing, waste paint and solvent recovery integrated equipment and technology. Background technique [0002] The surface painting decoration and paint curing technology of the workpiece have been widely used in the surface decoration process of various civil and national defense industrial products such as automobiles, motorcycles, household appliances, furniture, car models, etc. my country consumes tens of millions of tons of paint every year, and it needs tens of millions more Do not dilute the paint with organic solvents such as thinner. At present, the surface spraying decoration and paint curing of workpieces are directly operated by workers in two open workshops respectively. During the process of painting decoration and paint curing, a large amount of exhaust ...

AI Technical Summary

Problems solved by technology

At present, the spraying decoration and paint curing on the surface of workpieces are directly operated by workers in two open workshops respectively. During the process of painting decoration and paint curing, a large amount of exhaust gas and waste paint are generated, which pollute the environment.

Thinner volatilized inside the paint on the surface of the workpiece not only pollutes the environment, but is especially harmful to the health of workers in painting decoration and paint curing operations

Paint decoration and paint curing operators not only have a harsh working environment, but also have high technical requirements, and the quality of surface decoration industrial products of spray paint products is unstable
