SOLVENT PURIFYING APPARATUS AND SOLVENT FILTERING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a solvent purifying apparatus and a solvent filtering apparatus which can satisfactorily remove dirt in the rotational center of a spin disk filter when the spin disk filter is regenerated.;SOLUTION: In a first filter 8, the spin disk filter 36 is intermittently rotated in a state where a predetermined amount of solvent stays in a container 30, thereby always preventing a space 50 from being formed around the rotational center by moving the solvent in the container 30 away from the spin disk filter 36 by centrifugal force. As a result, when the spin disk filter 36 is regenerated, the rotational center of the spin disk filter 36 can surely strike the liquid surface 51 of the solvent in the container 30 to satisfactorily remove dirt in the rotational center of the spin disk filter 36.;COPYRIGHT: (C)2010,JPO&INPIT
