Abstract
A method and device for magnetically transporting finely divided magnetic particles accumulated or deposited at a space. First a DC magnetic field is exerted to the finely divided magnetic particles so as to magnetize and bring them into an easy-to-be-handled state and then revolving alternating fields are exerted to the magnetized, finely divided magnetic particles, thereby magnetically transporting them.
Claims4
Apparatus for transporting fine particles of which at least a part of magnetizable such as the CRUD particles accumulated in a nuclear reactor, comprising:
- (a) first magnetic field source means for applying a stationary magnetic field to magnetize the particles prior to transport;
- and
- (b) second magnetic field source means comprising a multi-phase generator with a plurality of ring-shapedly formed coils disposed on a cylindrical magnetic core and having a three-quarter full-pitch winding and operative on the particles magnetized by the first magnetic field source means for applying a revolving magnetic field to transport the magnetized particles.
Apparatus for transporting fine particles of which at least a part of magnetizable such as the CRUD particles accumulated in a nuclear reactor, comprising:
- (a) a first magnetic field source means comprising a direct current generator having a coil secured to a core rotatable above its axis for applying a stationary magnetic field to magnetize the particles prior to transport;
- and
- (b) second magnetic field source means operative on the particles magnetized by the first magnetic field source means for applying a revolving magnetic field to transport the magnetized particles.
