BOWL CENTRIFUGE Russian patent published in 1995 - IPC

FIELD: separation of liquid nonhomogeneous mixture by centrifugal force, may be used in pharmaceutical, chemical, metallurgical and other industries. SUBSTANCE: bowl centrifuge has housing 1, cylindrical-conical rotor 2, auger 3, pack of plates 6, windows 7 and 8 for discharging centrifigate and precipitate, pressure disk 9, feeding pipe 10, auxiliary shells 11 and 12 mounted concentrically about conical part of rotor 2. Collector 15 for supplying heated gas is positioned below end of rotor 2. Housing 1 is provided with heated gas discharge, branch pipe 16 disposed in its upper part. Lower end surface of conical shell 11 and upper end surface of outer conical shell 12 are provided with openings 17 and 18 disposed circumferentially and guiding blades 19 and 20 for supply and discharge of heated gas. Guiding blades 19 positioned on lower end surface of internal conical shell 11 are inclined in the direction of rotation of rotor 2 to provide for heated gas head. Guiding blades 20 positioned on upper end surface of outer conical shell 12 are inclined in the direction opposite to direction of rotation of rotor 2 to provide creation of vacuum in openings 18. Pocket 23 for collecting liquid pressed out of precipitate in shells 11 and 12 is disposed within housing 1. Housing 1 is provided with heat insulation 24. EFFECT: reduced moisture content of precipitate having increased dispersed phase. 4 dwg
