Gas filtering system of marine part spraying production line

Abstract

The invention relates to a gas filtering system of a marine part spraying production line. The gas filtering system comprises a gas filtering assembly covering the upper portion of spraying equipment, a conveying plate installed at the top of a conveying chain, an air outlet pipeline and an air draft pipeline, wherein one end of the conveying plate extends to the position below the gas filtering assembly, and the air outlet pipeline and the air draft pipeline are arranged in the conveying plate and symmetrically distributed relative to the conveying chain. One end of the air outlet pipeline communicates with a clean air outlet of the gas filtering assembly, the other end of the air outlet pipeline is connected with a plurality of air blowing openings penetrating through the lower surface of a conveying plate body, the air blowing openings are formed in the outer side edge of the lower surface of the conveying plate body, and the blown clean air forms an outer air curtain between A workpiece and the outside air at the outer edge of the conveying plate. According to the gas filtering system, comprehensive filtering treatment of pollution gas generated by workpiece spraying can be achieved, the safety of the production environment is guaranteed, a pipeline structure and the conveying plate of the whole gas filtering system are fused into a whole, the gas filtering plate assembly is arranged above the conveying chain, and the whole filtering system is small in occupied space, simple in structure and low in equipment cost.

Description

technical field [0001] The invention belongs to the technical field of spraying production lines, and in particular relates to a gas filter system of a spraying production line for marine parts. Background technique [0002] In industrial production, in order to further protect the product or make the surface of the product smoother and more beautiful, it is generally necessary to spray the surface of the product. The spraying process has been widely used in ships, automobiles, home appliances, plastics and furniture industries. [0003] Spraying is a coating method in which spray paint is dispersed into uniform and fine droplets and applied to the surface of the object to be coated by means of pressure by spraying equipment. In order to improve the efficiency of spraying, the existing spraying production line usually transports the workpiece to the spraying equipment through the conveyor chain and the spreader to realize continuous and uninterrupted operation. The paint is ...

Problems solved by technology

[0004] However, after the existing workpiece is painted, the paint particles will be emitted into the air, forming a large amount of irritating gas, which is not conducive to the health of the staff, and the production line is long, and the workpiece will also emit irritation during the transportation process on the production line after painting. Therefore, in order to maintain a tasteless or low-smell production environment, a gas filtration system with a volume matching the production line is required for gas filtration, so that the cost of the gas filtration system is relatively high, and it is integrated with the production line more difficult
