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

FIELD: metal working, in particular, plants for purification of aqueous and oily lubricant-coolants from ferromagnetic particles in process of abrasive working; may be used in filtering of large volumes of fluid with separation of large amounts of grinding slurry. SUBSTANCE: plant has vessel for purified fluid with inlet and outlet, magnetic system in the form of driven endless chain conveyor located inside the vessel with slurry collecting members attached to conveyor, device for cleaning of slurry collecting members. Vessel base is made inclined and stepped in shape. Discharge outlets are located in upper and lower parts of large side face of vessel. In this case, lower discharge outlet has device for regulation of liquid flow rate. Slurry collecting members are made in the form of magnetic units, rectangular in shape and presenting flat magnetic members of similar sizes and consisting of flat magnets similar in shape and installed in plates. Space between magnets is filled with wear-resistant filler. Plates have shunt and secured to beam at similar intervals. Beam is connected with driven endless chain conveyor. Device for cleaning of magnetic units is made in the form of comb. Screws are installed on all protrusions of comb. EFFECT: higher efficiency. 3 cl, 5 dwg
