Abstract
The utility model discloses an ore pulp de-foaming pool with a deflector. The ore pulp de-foaming pool comprises a work bin formed by the combination of a cylinder and a conical tube; the tangent direction of the circumference of the cylinder is provided with a feeding hole; the lower end of the conical tube is connected with the deflector; the outlet of the deflector is connected with a horizontal underflow foam pump; the central part of the work bin is provided with an exhaust tube; the exhaust tube is used for discharging air separated from foam ore pulp into the atmosphere so as to provide foam-free and pre-whirl-free ore pulp for the horizontal underflow foam pump; a strong swirl is generated in the container of the work bin by the foam ore pulp when the work bin is under the joint action of an inlet head and a suction head of the underflow foam pump. Under the action of a centrifugal force, gas is forcibly separated from the foam ore pulp, and is discharged by the middle exhaust tube; the ore pulp enters the inlet of the horizontal underflow foam pump after the pre-whirl of the ore pulp is eliminated by the deflector.
