Oil paint recycling device for spraying and working method thereof

Abstract

The invention discloses an oil paint recycling device for spraying and a working method thereof, relates to the field of coating, and aims at solving the problem that oil paint has viscosity and is liable to get attached to the wall in the collecting process. The oil paint recycling device is characterized by comprising a paint mist collecting mechanism, wherein the paint mist collecting mechanismcomprises a flow guide pipe, the flow guide pipe is provided with a paint mist entry channel which is used for collecting paint mist, an air guide mechanism which is used for guiding the paint mist,an alkaline liquor overflow mechanism which is used for lowering the viscosity of the paint mist and a paint mist escape channel which is used for discharging the paint mist from top to bottom in sequence, a paint mist collecting box is fixedly connected to the paint mist escape channel, and a reaction kettle used for regenerating the oil paint is connected to the paint mist collecting box. According to the oil paint spraying device, the paint mist is guided into the flow guide pipe through the air guide mechanism, the alkaline liquor overflow mechanism is utilized for lowering the viscosity of the paint mist, the situation that the oil paint is attached to the wall is reduced, the oil paint is conveniently collected into the paint mist collecting box, the discharge volume of VOC is reduced, then the reaction kettle is utilized for treating the collected oil paint so that the oil paint can become recyclable oil paint, and thus energy conservation and emission reduction are achieved.

Description

technical field

[0001] The invention relates to the field of painting, more specifically, it relates to a paint recycling device for spraying and a working method thereof. Background technique

[0002] At present, the workpiece is sprayed with a spray gun in the process of spraying. The paint is atomized into particles through the spray gun. Due to the shape and size of the workpiece, a large amount of paint mist is not absorbed by the workpiece and is discharged into the outdoor environment with the exhaust system. Only about 40- 70% of the paint evenly accumulates on the workpiece to form a coating film, and nearly half of the paint particles are atomized with the solvent to form a large amount of highly dispersed overspray paint mist that fills the spray chamber, resulting in a large amount of waste of paint and an increase in production costs , and discharge after simple treatment will cause environmental pollution.
