METHOD OF CLEANING OF LIQUIDS AND UTILISATOION OF MAGNETIC SLIMES AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2009 - IPC C02F1/48 C02F11/00 

FIELD: metallurgy.

SUBSTANCE: method includes passing of cleaned liquid through magnetic separators with following dewatering of slime products. Liquid purification is implemented on pressure magnetic separators of closed type, and cleaned liquid is collected in tank-collector and it is used in the capacity of cleaning fluid for purification of pressure magnetic separators of closed type against slime. Received slime is thickened in magnetic separator of open type and fed to dewatering. Liquid extracted during dewatering of slime product is directed into tank of magnetic separator of open type and cleaned in magnetic separator of open type flushing liquid - into pressure magnetic separator of close type. Device includes source of liquid pollution by magnetic inclusions, which by means of pump and pipeline of liquid supply is connected to as minimum two pressure magnetic separators of close type. Pressure magnetic separators of close type by means of pipelines and slide valves are connected to tank-collector and magnetic separators of open type which is by means of conveyor is connected to filter of dewatering.

EFFECT: upgrading of liquids purification, reduction of cost price of cleaning, power inputs, reduction of device's overall dimentions.
