FIELD: production of alumina; chemical hydrometallurgical, concentration and other industries. SUBSTANCE: proposed device includes receiver connected with distributing head of vacuum filter by means of high and low vacuum pipe lines, vacuum system and hydraulic seal. Receiver is divided vertically into three chambers by means of partitions: upper chamber is connected with vacuum pipe line, center chamber is connected with low vacuum pipe line and lower chamber is used as drip pan. All chambers are connected with hydraulic seal by means of pipe lines; two pipes are coaxially mounted along axis of receiver; upper part of pipe of lesser diameter is connected with vacuum system and its lower part is located in drip pan. Pipe of larger diameter is connected to partitions and is brought into communication with center by means of hole available in its wall and closed by shut-off member. EFFECT: improved quality of dehydration of sediment due to adjustable differentiated vacuum. 2 cl, 1 dwg
