SETTLING TANK FOR PURIFICATION OF CUTTING-TOOL COOLANT Russian patent published in 1997 - IPC

FIELD: cleaning cutting-tool coolants and other technological liquids from mechanical impurities. SUBSTANCE: settling tank has housing, chain conveyer and hollow case positioned between conveyer branches and provided with fixed and movable permanent magnets attached to internal surfaces off upper and lower ends of hollow case. Permanent magnets are proposed to be installed on nonmagnetic axles and combined so that they form magnetic rods attached to side walls of hollow case. It is also proposed to arrange permanent magnets as parallel rows in nonmagnetic holders attached to side walls of hollow case. Another proposal is to install magnetic chain separator in hollow case so that magnetic rods of this separator fit to internal surface of hollow case. It is proposed further to provide hollow case with protective screen covering hollow case surface, which is not in contact with internal flights of conveyer. EFFECT: improved efficiency of cleaning operation. 6 cl, 6 dwg
