Title:
PURIFYING APPARATUS
Document Type and Number:
Japanese Patent JP3314350
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a purifying apparatus which can continuously carry out magnetic separation.
SOLUTION: A high gradation magnetic filter passing a magnetic field space generated by a plurality of magnets 33a, 33b which generate magnetic fields in the flow direction of a fluid to be treated is constituted of at least two magnetic filters 48b, 48c parted by a water-tight diaphragm 49b and at the time when the fluid to be treated flows in to the magnetic filter 48b, the magnetic filter 48c is so arranged as to be out of the flow of the fluid to be treated and a housing part 46b, which is parted from atmosphere and houses the magnetic filter 48c arranged to be out of the flow of the fluid to be treated, is installed and a means (the diaphragm 49b) to part the housing part 46b from the fluid to be treated which flows in the magnetic filter 48b is installed and dummy magnetic filters 48a, 48d are installed in the end parts in the mutually remote sides of the magnetic filters 48b, 48c. Consequently, even in the case any one of the magnetic filters 48b, 48c is set to be out of the flow of the fluid to be treated, the magnetic filters 48a, 48d are out of the magnetic field space formed by a plurality of the magnets.
