Foundry sand processing system

Abstract

The present invention relates to sand treatment equipment, in particular to a foundry sand treatment system, which includes a filter mechanism, a horizontal transmission mechanism, an inclined transmission mechanism, a magnetic ring group, a sand storage box and a waste residue box. The sand port is detachably connected to the filter plate; the horizontal transmission mechanism includes a rotating shaft and a conveyor belt driven by the rotating shaft; the inclined transmission mechanism includes a stepped platform and an inclined plate arranged on each stepped platform, and the sand inlet of the sand storage box is lower than the inclined The sand output end of the transmission mechanism; the magnetic ring group is set on one side of the inclined transmission mechanism and is close to the inclined plate. The magnetic ring group includes a magnetic ring, a drive shaft that drives the magnetic ring to rotate, and a scraper for removing iron filings from the magnetic ring , the scraper is set obliquely and its scraper end is against the magnetic ring, and the discharge end of the scraper extends to the waste residue box. The foundry sand processing system adopting the technical solution of the present invention can effectively remove iron filings in the foundry sand, avoid the trouble of manual cleaning, and ensure the safety of the next process.

Description

technical field [0001] The invention relates to sand processing equipment, in particular to a foundry sand processing system. Background technique [0002] A large amount of sand needs to be used in the lost foam operation process. The sand is often doped with iron nails, iron filings and other sundries, which do not meet the requirements of use. It is necessary to remove iron from the sand, and in order to save resources, it is necessary to be able to remove the lost foam The sand used in the mold casting process is recycled and reused. Before the next step, the iron nails, iron filings and other sundries must be removed. At present, this kind of work mainly depends on manual screening and cleaning. This method is not good for cleaning iron filings, etc. Thoroughly, it will bring hidden dangers to the next process. Contents of the invention [0003] The purpose of the present invention is to solve the above technical problems and provide a foundry sand processing system,...
