CENTRIFUGAL FILTRATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a horizontal type centrifugal filtration apparatus capable of efficiently recovering crystals from a basket without using crystal suction tubing. SOLUTION: A scratch driving shaft 21 is inserted into the basket 10. Attached to the scratch driving shaft 21 are a scratching cutting member 31 having a crystal transfer portion 31c for discharging scratched crystals out of the basket, auxiliary scratching cutting members 32 and 33 having inclined surfaces such that scratched crystals can be moved towards the scratching cutting member 31. Crystals scratched with the auxiliary scratching cutting members 32 and 33 are moved towards the scratching cutting member 31. The crystals moved by the auxiliary scratching cutting members 32 and 33 are scratched by the scratching cutting member 31 and discharged out of the basket through the transfer portion 31c.
