Recovery system and method of cast spraying paint

Abstract

The invention discloses a recovery system of cast spraying paint. The recovery system comprises a spraying tank; the bottom of the spraying tank is connected with a paint stirring tank; an intake pipeline and a paint pipeline are leaded into the spraying tank; an inlet of the paint pipeline extends into the bottom of the spraying tank, and an outlet is connected with a nozzle; and one end of the intake pipeline is arranged at the top of the spraying tank. The recovery system and method have a function of realizing recovery of paint in the spraying tank into the paint stirring tank through introducing gas, and prevent the problem of manual carrying recovery; meanwhile, a cleaning pipeline is connected; the cleaning pipeline can clean paint remained in the spraying tank and the nozzle; cleaning liquid is recovered into the paint stirring tank after cleaning; the paint in the cleaning liquid is recovered; solution is used for diluting the paint after cleaning; and the recovery system has the advantages of labor saving, low labor intensity, high recycling rate and high economic benefit.

Description

technical field [0001] The invention relates to the field of casting paint recycling, in particular to a recycling system and method for casting spray paint. Background technique [0002] During the automatic centrifugal casting operation, the iron mold must be sprayed with heat-resistant paint to prevent the thermal shock of the metal iron mold, improve the service life of the iron mold, adjust the thermal resistance of the system, control the cooling speed, and ensure that the structure and performance of the casting meet the requirements , so paint spraying is an important process link of centrifugal casting; at the same time, the suspension, fluidity and viscosity of paint have a great influence on the structure and performance of castings, so it is required to return the remaining paint in the spray tank to the primary paint mixing tank after each shift . However, for a long time, the bottom valve of the spraying tank has been manually switched to recover the remaining...

Problems solved by technology

However, for a long time, the bottom valve of the spraying tank has been manually switched to recover the remaining paint with the paint bucket, and it is manually transported to the first-level paint mixing system or paint bucket, and then the spraying tank is cleaned manually; the manual labor intensity is high, and it is easy to cause the working environment. Pollution, or even forgetting to dispose of the remaining paint causing product quality problems in the next shift, etc.
