Claim 0:
1. A flocculation and magnetic separation device, comprising:
a stirrer for stirring a fluid that contains plastics and plankton putting flocculant, magnetic material, and polymer into said fluid to produce flocs;
a first magnetic drum having magnets on the surface thereof to attract said flocs thereon and rotating in the direction opposite to the flow direction of said floc-contained fluid to create eddies for attracting said flocs thereto;
a second magnetic drum having magnets on the surface thereof to attract said flocs, and rotating in the same direction as a fluid of which flow direction being changed at a protrusion arranged at the rear of said first magnetic drum so as not to cause peeling off of said flocs attracted to said second magnetic drum;
a floc recovering section for recovering by grouping said flocs attracted to said first magnetic drum and to said second magnetic drum into one; and
a pipe into which a fluid containing plastic broken by a slit mechanism flows;
wherein said slit mechanism has
a first slit section provided on said pipe at a predetermined angle; and
a second slit section provided at the rear stage of said first slit section at an angle different from said predetermined angle;
wherein the cross section of both a slit plate of said first slit section and a slit plate of said second slit section is acute with respect to the flow-in direction.
