Patent ID: 8701893

Claim:
A magnetic separation device, comprising: a first magnetic field unit, comprising: a plurality of first magnets; and a plurality of first magnetic yokes respectively interposed between the plurality of first magnets, wherein a same magnetic pole of each adjacent two first magnets is facing the respective first magnetic yoke interposed therebetween, a gap is formed between each adjacent two of the first magnets and a first sidewall of the respective first magnetic yoke interposed therebetween not in contact with the adjacent two of the first magnets, and the first magnetic yokes and the first magnets are formed from different materials; and a first separation unit, comprising: a body made of non-magnetic materials disposed adjacent to a first side of the first magnetic field unit; and a continuous piping disposed in the body, comprising a plurality of second sections interposed respectively between a plurality of first sections, wherein the second sections are perpendicular to the first sections, and each second section is respectively adjacent to and parallel to the first sidewall of a corresponding one of the first magnetic yokes, wherein each second section has a portion protruding from a first side of the body of the first separation unit and received in the gap formed by the first sidewall of the corresponding one of the first magnetic yokes.
