<P>PROBLEM TO BE SOLVED: To provide a magnetic separator which can increase a probability of capturing magnetic particles by their adhesion to non-magnetic materials, and reuse magnetic particles not adhering to the non-magnetic materials. <P>SOLUTION: The magnetic separator magnetically attracts and separates a non-magnetic material by adding magnetic particles into a non-magnetic material-containing liquid to be treated, causing the magnetic particles to adhere to the non-magnetic material and magnetically attracting the magnetized non-magnetic material by a magnetic filter. A magnetic separation part is installed in a pipe for the liquid to be treated into which the magnetic particles are added, and is divided into a magnetically attracting section, a magnetization section, and a magnetic particle remixing section from the downstream side. In the pipe, a plurality of the magnetic filters are axially installed side by side, and a moving means for moving the magnetic filters toward the upstream side is installed. The magnetic particles magnetically attracted to the magnetic filters in the magnetic attraction section are separated from the magnetic filters in the magnetic particle remixing section to migrate into the liquid to be treated, and the migrating magnetic particles are made to re-adhere to the non-magnetic material. The moving velocity of the magnetic particles migrating in the liquid to be treated in the magnet-carrying section is made higher than that of the non-magnetic material in the liquid to be treated, thereby facilitating the adhesion of the magnetic particles to the non-magnetic material. <P>COPYRIGHT: (C)2009,JPO&INPIT |
