Abstract
A magnetic separator and process involving a train of parallel, spaced magnetic bars connected together to form a closed loop disposed in a tank able to receive a liquid containing ferromagnetic particles which are to be removed from the liquid. The liquid is introduced by an inlet extending within the closed loop so that the liquid is constrained to flow out through spaces between the magnetic bars. Flow out of the tank is through perforate distributor plates and over a pair of weirs, the perforate plates and weirs extending along a respective side of the closed loop to distribute the flow through all of the bar spaces.
Claims10
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 of bars defining a closed space within;
- a loop drive advancing said loop of bars in a recirculating path around said space within said tank;
- an inlet directing liquid into said closed space in said tank within said loop of magnetic bars;
- and,
- at least one outlet located outside said loop of bars for drawing liquid out of said tank after passing radially out of said closed space through spaces between said bars on each side of said inlet;
- an intervening space between said loop of magnetic bars and a tank sidewall on each side of said loop, and
- a perforated distributor disposed in each intervening space extending vertically down each side of said loop of bars to distribute flow into said spaced apart bars to said at least one outlet.
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 to define a closed space within said tank;
- introducing liquid containing said ferromagnetic particles into said tank through an inlet extending into said closed space within said closed loop of magnetic bars;
- and
- inducing a radial outflow of liquid out of said closed space and through spaces between said bars on each side of said inlet and out of said tank through at least one tank outlet located outside said closed space defined by said closed loop of magnetic bars.
