Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, and more specifically, to a dust and volatile organic compound collection device for a coating production line. Background Art

[0002] A coating is a continuous film that is coated on the surface of an object to be protected or decorated and can form a firm attachment with the object to be coated. It is usually mainly composed of resin, oil or emulsion, with or without pigments and fillers, and corresponding additives are added. It is a viscous liquid prepared with organic solvents or water. During the coating production process, raw materials will float into the air and need to be collected by a collection device to achieve clean production.

[0003] Based on the above, the inventor found that: the existing collection device mainly collects floating objects through an air pump and pipe fittings. However, due to the large range and many production steps of the coating production line, the fixed absorption pipe fittings cannot fully perform the collection work. And if multiple pipe fittings are set up in cooperation, it will increase the cost of collection and cleaning. Therefore, in view of this, the existing structure is studied and improved to provide a dust and volatile organic compound collection device for a coating production line, in order to achieve a more practical value.
