Magnetic grinding material screening, filtering and recovery device and method

Abstract

The invention relates to a magnetic grinding material screening, filtering and recovery device and method. The magnetic grinding material screening, filtering and recovery device comprises a base, a screening device, a filtering device, a grinding material recovery device and sliding rails. The multiple sliding rails which are parallel to each other are fixed to the base, and the filtering deviceand the grinding material recovery device are connected with the base in a sliding mode through the sliding rails. The screening device is arranged above the filtering device and the grinding materialrecovery device. The method comprises the steps that magnetic grinding materials, workpieces, a grinding fluid mixture and water are poured into the screening device, and magnetic grinding particlesprecipitate at the bottom of a screening barrel; the magnetic grinding materials are attracted at the bottom of the barrel wall of the screening barrel by a small electromagnet; grinding chips and anaqueous solution inside the screening barrel are poured into a filtering barrel, and the grinding chips are filtered out by a sponge; the magnetic grinding materials are attracted by a large electromagnet; and after drying treatment is accomplished, the large electromagnet is deenergized, and the magnetic grinding materials are recovered. The magnetic grinding material screening, filtering and recovery device and method have the advantages that separation of the grinding materials and the workpieces can be rapidly achieved, recovery of the magnetic grinding materials can be efficiently accomplished, and the degree of automation is high.

Description

technical field [0001] The invention relates to a magnetic abrasive screening, filtering and recycling device and method. Background technique [0002] With the rapid development of precision manufacturing industries such as aerospace and automobiles, many complex parts have also emerged, such as special-shaped parts such as space bends and blades on aircraft engines. It is difficult to realize the finishing processing of special-shaped parts by traditional machining methods. The magnetic grinding method can effectively remove processing defects such as burrs and microcracks of special-shaped parts. Although the magnetic grinding method can smooth complex parts, the magnetic abrasive (magnetic needle or magnetic abrasive particle) and the workpiece need to be separated manually after grinding. The used magnetic abrasives are directly discarded and cannot be recycled and reused. [0003] Chinese patent CN1082743832A discloses a grinding device with waste recycling function...

AI Technical Summary

Problems solved by technology

[0003] Chinese patent CN1082743832A discloses a grinding device with waste recycling function, which can only simply recycle waste after grinding, but fails to recycle magnetic abrasives and aqueous solution after grinding

[0004] At present, most of the magnetic abrasives are discarded after one processing, resulting in waste of resources

At the same time, in the prior art, the recovery of abrasives has not been dried in time to reduce the corrosion of abrasives by air and water, which affects the grinding quality.
