DEVICE FOR PURIFICATION OF LIQUIDS FROM FERROMAGNETIC PARTICLES Russian patent published in 1997 - IPC

FIELD: metal machining; may be used in-process purification of lubricant-coolants from finely divided ferromagnetic particles. SUBSTANCE: device has vessel for purified liquid with inlet and outlet, magnetic system in the form of driving endless chain conveyor located inside the vessel. Secured to conveyor are magnetic rods whose axes are aligned with axes of inlet and outlet. Shaft of chain of driving endless conveyor has head from one side, and on the other side it has end piece with transverse groove and ring whose outer and inner surfaces have grooves, and ring end face has recess. Axle of magnetic rid has spherical end piece with cap having groove. Ring is connected with chain shaft and cap by means of clamps installed in grooves on end piece, on inner and outer surfaces of ring and cap. Installed in recess is insert, and conical sealing washers are installed between inner plates and end faces of freely rotating roller and between inner and outer plates on the side of shaft head. Chain shaft has longitudinal groove whose length is shorter than bushing length. EFFECT: higher efficiency. 2 dwg
