Claims
- 1. A magnetic separator for removing ferromagnetic particles suspended in a liquid, said separator comprising a tank adapted to contain a liquid;
a train of spaced apart elongated magnetic bars connected together and arranged within said tank in a closed loop; a loop drive advancing said loop of bars within said tank; an inlet directing liquid into said tank within said loop of magnetic bars; and, at least one outlet located outside said loop for drawing liquid out of said tank after passing through spaces between said bars.
- 2. The separator according to claim 1 wherein said loop of magnetic bars is located in said tank with an intervening space between said loop and a tank sidewall on either side of said loop, and wherein a pair of outlets each communicating with a respective space is located on a respective side of said loop of magnetic bars.
- 3. The separator according to claim 1 wherein said outlet include a weir extending along each side of said loop at a predetermined level in said tank.
- 4. The separator according to claim 2 further including a vertical perforated distributor place positioned in each intervening space causing distributed flow out to a respective outlet.
- 5. The separator according to claim 1 wherein said inlet comprises a pipe extending across said tank and within said loop of magnetic bars, said pipe having openings along the length thereof to distribute flow out of said pipe and into said tank along the length of said pipe.
- 6. A process for removing ferromagnetic particles from a liquid comprising the steps of:
providing a tank for containing said liquid; providing a train of spaced apart connected magnetic bars arranged in a closed loop suspended within said tank; introducing liquid containing said ferromagnetic particles into said tank through an inlet extending within said closed loop of magnetic bars; and inducing an outflow of liquid out through spaces between said bars and out of said tank through at least one tank outlet located outside said closed loop of magnetic bars.
- 7. The process according to claim 6 wherein in said step of introducing said liquid into said tank, said flow is introduced through an elongated slotted pipe extending within said loop of connected magnetic bars to distributed flow along the length of said bars.
- 8. The process according to claim 6 wherein in said step of inducing flow out of said tank, outflow of said liquid is directed over at least one weir extending alongside said magnetic bars.
- 9. The process according to claim 8 wherein in said inducing step, outflow is directed over a weir extending alongside said magnetic bars on each side of said closed loop.
- 10. The process according to claim 6 wherein in said step of inducing flow out of said tank includes the step of distributing flow between all of the spaces between said magnetic bars immersed in said liquid by positioning in said tank a distribution plate having openings therein adjacent each side of said closed loop so as to intercept outflow from said tank to thereby distribute flow through substantially all of the spaces between said magnetic bars immersed in said liquid.
