PLANT FOR PURIFICATION OF LIQUID FROM FERROMAGNETIC PARTICLES Russian patent published in 1998 - IPC

FIELD: metal working, in particular, plants for purification of aqueous and oil lubricants-coolers from ferromagnetic particles in process of abrasive machining; applicable in grinding and honing machines in filtering of large volumes of liquids with separation of large amount of grinding slime. SUBSTANCE: plant has vessel, magnetic system with slime collecting members, device for cleaning of slime-collecting members. Vessel base is made cylindrical in shape. Magnetic system with slime-collecting members is essentially a hollow cylindrical drum with rectangular ports. Installed inside drum on guides are rectangular magnetic units and cam mechanism for displacement; installed inside the drum is pressing-out roller with spring. Magnetic unit consists of upper and lower magnetic members. Upper magnetic members are hermetically installed in ports on the surface of hollow cylindrical drum and located in same plane with respective lower magnetic members installed on ferromagnetic base for coaxial displacement of lower magnetic members relative to the upper ones by means of cam mechanism. EFFECT: higher degree of purification of lubricants-coolers, improved convenience of operation and operation efficiency. 4 dwg
