Abstract: A U-shaped side of a yoke is mounted on the confronting sides of two rotating plates attached to the inside of a magnetically agglomerating and treating tank, and a plurality of magnets, each having a magnetic force of not less than 12,000 gausses, are mounted on the confronting sides of the yoke, respectively, and the gap between the faces of the confronting magnets is set at 300 mm to form a magnetic field. Liquid containing impurities, such as magnetic and non-magnetic suspensions is caused to flow into this magnetic field for contact with the magnets for a predetermined period of time, so that the non-magnetic suspension is magnetically agglomerated together with the magnetic suspension, so as to be attracted to the magnets, and the magnetically agglomerated matter adhering to the surfaces of the magnets is separated.

Abstract: An apparatus for separating solids from various types of liquid is disclosed, which includes a vessel for a filtrate arranged adjacent to one side wall of receiving vessel for a solid-containing liquid, and a disc screen arranged at an opening of the side wall using a liquid seal, the disc screen being connected to a rotary shaft which in turn is connected to a driving source, while the disc screen at its surface of the filtrate vessel side being opposed with a submerged ejecting nozzle for a washing fluid thereby to backwash the disc screen during its rotation, resulting in an excellent solid/liquid separator having capability of preventing the clogging of the solids in the screen and continuous operation, as well as the compactness and high capacity of the apparatus. The apparatus according to the invention may be applied effectively to the separation of, for example, chips from a coolant for various machines.
