A kind of container paint automatic intelligent paint mixing conveying system and using method

Abstract

The invention discloses an automatic intelligent container paint mixing and conveying system. The automatic intelligent container paint mixing and conveying system comprises a paint conveying mechanism, an intelligent online metering paint mixing mechanism and a tube-type mixer, wherein the paint conveying mechanism is connected with a transition barrel, the intelligent online metering paint mixing mechanism is arranged between the transition barrel and paint mixing barrels, the intelligent online metering paint mixing mechanism comprises pneumatic control ball valves, online meters and an automatic control box, the tube-type mixer is connected with a multi-path distributor which is provided with one or more outlets, the outlets are connected with a paint spraying machine through arranged paint spraying pumps, the multi-path distributor is connected with a low-pressure circulation loop, and a pipeline between the paint spraying pumps and the paint spraying machine is further provided with a high-pressure cleaning loop. According to the automatic intelligent container paint mixing and conveying system and a using method thereof, labor intensity of operating personnel is relieved through full automatic running, and the situation that an inaccurate paint mixing proportion or mistaken use of solvents leads to scrapping of a whole barrel of paint or damage to the surface of a container can be avoided.

Description

technical field [0001] The invention relates to an automatic intelligent paint mixing conveying system for container paint and a use method thereof. Background technique [0002] At present, the production of containers in the world is basically all made in China. Because the containers are mainly transported by sea, the requirements for the coating of the surface paint are very high, and they need to have good anti-rust performance, so the paint on the surface needs to be Spraying three layers of paint with different properties requires high paint film thickness, and the surface paint film thickness is required to reach more than 160 microns. Therefore, the amount of paint used in containers is very large, and the annual amount of paint used in a production line is more than tens of thousands of tons. However, in the existing container paint line, such a large amount of paint needs to be adjusted in proportion before spraying can be carried out. However, in the current si...

Problems solved by technology

However, in the current situation, the vast majority of container production lines now use manual deployment for the deployment of paint. Now a shift uses dozens of tons of paint, and the workload of the paint is very large, so the labor of the paint mixer The strength is very high. Furthermore, the ratio of the various paints needs to be controlled by an experienced paint mixer. If the composition of each paint is not well proportioned, or sometimes the wrong solvent is used, the entire bucket of paint will be scrapped. Or cause the surface of the container to be sprayed, some people in the industry have proposed whether the automatic deployment of paint can be used to solve this problem, that is, it is proposed to adopt a fully automated intelligent paint mixing and conveying system, and the four kinds of paint used in the container—" Zinc-rich paint, intermediate paint, interior paint and top paint" are automatically and intelligently blended and delivered to the paint supply pumps, and the entire paint mixing system can be cleaned automatically or semi-automatically. Therefore, a special design for Automatic intelligent deployment of paint and delivery system
