Water-based paint drying system

Abstract

The invention relates to the technical field of drying systems, in particular to a drying system for water-based coating. The system is provided with a sealed air duct and at least comprises a drying room, a heat pump unit and a burner, wherein the drying room can provide a sealed drying space and is provided with an air inlet end and an air return end; the heat pump unit comprises an evaporator, a compressor and a condenser, the compressor drives coolant to pass the condenser and the evaporator in a circulation manner, the evaporator is connected to the air return end of the drying room to provide return air for cooling and dehumidifying, and the condenser is connected to the air outlet end of the evaporator to provide dry air for heating; the burner is arranged between the condenser and the air inlet end of the drying room, and the burner combusts, oxidizes and purifies dry hot air and then conveys the same to the drying room. The drying system provided with the sealed air duct and drying space is convenient to mount, small in floor space, capable of being mounted indoor or outdoor, capable of reducing energy consumption, even in drying space temperature, capable of shortening the drying time of the water-based coating, capable of reducing operation cost, safe and reliable in operation, environmental friendly and free of pollution, wide in application range, and capable of achieving continuous large-scale drying in a production line mode.

Description

technical field [0001] The invention relates to the technical field of drying systems, in particular to a water-based paint drying system. Background technique [0002] With the improvement of society's awareness of environmental protection, environmentally friendly materials have been greatly promoted and applied. Water-based paint is one of them. Water-based paint is a paint that uses water as a diluent and does not contain organic solvents. It can be used on various materials such as wood, metal, plastic, glass, and building surfaces, and gradually replaces oil-based paint; especially for furniture. In terms of products, the current use of water-based coatings is gradually increasing. However, the existing furniture with water-based paint is mainly processed by parking and drying naturally, which requires a large space and a long drying time, which is not conducive to the rapid operation of enterprises. Then came the auxiliary hot air drying method. Although this method...

However, the existing furniture with water-based paint is mainly processed by parking and drying naturally, which requires a large space and a long drying time, which is not conducive to the rapid operation of enterprises

Then came the auxiliary hot air drying method. Although this method shortens the drying time, the angle and coverage of the hot air blowing are limited, so that the heat on different parts of the product is not balanced, and the degree of drying is different, which can easily cause local overheating of the product. Fission or deformation, and the existing hot air drying still has the defects of high energy consumption and high operating cost
