DISK VACUUM FILTER Russian patent published in 2004 - IPC

FIELD: black and a nonferrous metallurgy; and also in a chemical and other industries.

SUBSTANCE: the invention is intended for dehydration of suspension and may be used in black and a nonferrous metallurgy, chemical and other industries. The disk vacuum filter contains a bath with the suspension, a located above it a cellular shaft with channels linked to the inlet branch-pipes with the sectors of the filter located along the cellular shaft circumference forming the disks installed with possibility of partial immersing in the bath with suspension during rotation of the cellular shaft, and also a distributive head with a branch-pipe of withdrawal of filtrate. The area S₁ of the cross-section of the channel of the cellular shaft in the plane of the first branch-pipe spaced from the distributive head with a sector exceeds S₂ - the area of the cross-section of the channel of the cellular shaft in the plane of the next branch-pipe spaced from the distributive head with a sector_{exceeds S3... and so on up to Sn - the area of cross-section of the channel of the cellular shaft in the plane of the last branch-pipe spaced from the distributive head with a sector, i.e. S1>S2 > S3 ... Sn , at thatS1 - is less or equal to cross-sectional area of a branch-pipe of withdrawal of the filtrate from distributivehead Spr , andSn is more or equal to cross-sectional area of the inlet branch-pipe Sвп . The surface of the channel of the cellular shaft with linked to it the inlet branch-pipes with sectors of the filter is in parallel to the axis of spinning of the cellular shaft, and the opposite surface of the channel of the cellular shaft is under an angle to the axis of spinning of the cellular shaft. The technical result is an increase of efficiency of process of dehydration at the expense of a decrease of a hydraulic resistance and usage of the gravitational component of the filtrate motion.}

EFFECT: the invention allows to increase efficiency of dehydration process at the expense of a decrease of the hydraulic resistance and usage of the gravitational component of the filtrate motion.
