Description

TECHNICAL FIELD

[0001] The utility model relates to a container surface spraying production line water-based paint spraying paint mist trapping device belongs to spraying production line paint mist trapping device field. BACKGROUND

[0002] Based on the concept of environmental protection, health and safety and the upstream raw material of water-based paint, the development of supporting, technology research and development, talent reserve and coating application technology gradually mature, water-based paint has made great progress, and is widely used in rail transportation, container, wind power, engineering machinery equipment and other industrial fields.

[0003] Although water-based paint uses water as solvent, replaces most of toxic, harmful, flammable and explosive, and has safety hazards organic solvents, but in order to meet the requirements of film appearance quality, adhesion, drying rate adjustment and other requirements, some solubilizing agents, film forming additives and other substances are added, which belong to VOCs category. In the water-based paint coating application process, these VOCs and the paint mist lost by spraying must be uniformly trapped, and the organized treatment, discharge and recycling are carried out, so as to reduce the ecological environment pressure and resource waste.

[0004] At present, in the production line of container spraying water-based paint, self walking gantry reciprocating machine is used for spraying operation, the spraying speed is fast, the production efficiency is high, but the paint mist is scattered everywhere with the rapid movement of the spraying machine, which can be attached to the surface of the slide rail and the chain and even enter the inside of the chain, increase the running resistance and power consumption of the chain, and reduce the running stability, most of the VOCs in it also volatilize to the surrounding airspace.

[0005] The production line of container spraying water-based paint only has a relatively closed space, a large range of VOCs trapping system device, lacks a local airspace, a small range of paint mist trapping device, most of the paint mist floats in the air and then naturally settles on the surface of the isolator (usually disposable colored cloth, plastic cloth and the like), and is attached to the surface after complete drying, forming a layer of paint solid mixture, which is regularly discarded together with the isolator, or the paint attached to the surface of the isolator and the chain is washed by high pressure water and then flows into the drainage ditch, causing great resource waste and environmental pollution.
