BARREL-TYPE FILTER-DRIER Russian patent published in 1996 - IPC

FIELD: chemical engineering. SUBSTANCE: housing with jacket and pipeline fastened on hollow shaft is equipped with stationary device which is located in housing on one axis with hollow shaft and consists of two internal hulls sleeves rigidly connected with housing and forming spaces between internal sleeves and stationary external sleeves which have pipelines for product input and output. Rotation of internal sleeves relative to stationary external ones is carried out owing to bearings. Cavity separation is fulfilled due to sealing system. Upper part of housing is hermetically closed by cobber which is separated from housing by filtering partition. Rotation of shaft mounted in bearings is exercised from drive. Discharging connecting pipe is located in lower part of housing. Filter is used in apparatuses for carrying out processes of filtering suspensions, washing, squeezing out, drying and sediment discharging. EFFECT: enhanced efficiency. 2 dwg
