High-pressure water-sand jet-flow paint remover for plastic fender guard of automobile

Abstract

The invention relates to a high-pressure water-sand jet-flow paint remover for a plastic fender guard of an automobile. The high-pressure water-sand jet-flow paint remover comprises an electric control module, a high-pressure water jet-flow generation module, a sand mixing module, a jetting module, a workpiece loading module, a sewage collection treating module and a filtering module, wherein one end of the high-pressure water jet-flow generation module is connected with a filtering module, the other end of the high-pressure water jet-flow generation module is connected with the sand mixing module, one end of the jetting module is connected with the sand mixing module, the other end of the jetting module is connected with the workpiece loading module, one end of the sewage collection treating module is connected with the workpiece loading module, the other end of the sewage collection treating module is connected with the filtering module, and the electric control module is respectively connected with the sewage collection treating module, the sand mixing module, the jetting module and the sewage collection treating module and is used for outputting a control signal. The high-pressure water-sand jet-flow paint remover disclosed by the invention has the advantages of simple operation process, high paint removing efficiency, good effect, small labor strength, low cleaning cost and small environment pollution, and is suitable for paint removing operations of large-batch fender guards or other waste structural assemblies.

Description

technical field [0001] The invention relates to a device in the technical field of recycling automobile exterior trim products, in particular to a high-pressure water-sand jet paint removal device for plastic bumpers of scrapped automobiles. Background technique [0002] At present, the number of automobiles in my country has exceeded 100 million, and nearly 5 million automobiles need to be scrapped every year, resulting in a large amount of waste plastic bumpers. Recycling of plastic parts of scrapped automobiles can not only promote the development of automobile remanufacturing, but also is an important way to solve the social pollution problems caused by waste passenger car plastics, which is in line with the development requirements of the national circular economy. Paint removal is the most important and critical process in the process of bumper recycling. The quality of paint removal directly affects the level and quality of reuse of waste bumper materials. The irregu...

AI Technical Summary

Problems solved by technology

The paint removal effect and processing capacity of this method are relatively low, and the waste liquid produced is relatively harmful to the environment.

In addition, some enterprises adopt the pyrolysis method for recycling, and use the recycled bumpers to pyrolyze and refine fuel oil or gas, but the residual products after pyrolysis are difficult to dispose of, and are prone to secondary pollution

Therefore, the traditional bumper paint removal method is difficult to meet the requirements of bumper high value-added recycling, national clean production and sustainable development, and it is necessary to develop a new clean, efficient and environmentally friendly paint removal method
