Shandong heavy industry Weichai group casting and forging company draws on the strengths of others, takes recycling resources and reducing environmental pollution as the starting point, selects domestic advanced production technology, combined with reasonable and efficient structural design, and uses the 672 square meters space of the casting industrial park to design and build a 3-ton/hour old sand cooling regeneration line and a 5-ton/hour old sand heating regeneration line. In the thermal regeneration line, after crushing, screening and magnetic separation, the waste sand is evenly added to the roasting furnace, and the burner heats and roasts the waste sand to remove the film, and then after cooling treatment, the old sand can be regenerated. The 3 T/h old sand cold regeneration system is a specially designed regeneration system, especially the after-sales service system in the later stage, which uses the scattered sand collected by the company's aging furnace. The system directly grinds and sorts the scattered sand after filtration, and it is not roasted in the roasting furnace. Compared with the thermal regeneration system, it is more energy-saving and environmental friendly. According to statistics, as of the end of August, the cold and hot method of old sand regeneration totaled more than 1500 tons. 10007 sets of high-speed machine cylinder blocks should be cleared for their surrounding environment. The qualified rate of castings produced with recycled sand is no different from that of new sand core making, and the surface quality of sand core will be a revolution in the printing industry, which is much better than that of new sand core making. The recycling of foundry waste sand can not only solve the pollution of organic resin waste in waste sand to land and water resources, but also recycle silica sand and reduce resource exploitation. Weichai old sand recycling project will promote the company to the forefront of environmental protection in the production of poly (aryl ether ketone) by five major companies in the world
