Vertical type centrifugal ore separator used for hematite separation and capable of achieving continuous ore discharge

Abstract

The invention discloses a vertical type centrifugal ore separator used for hematite separation and capable of achieving continuous ore discharge. The vertical type centrifugal ore separator is composed of a feeding device, a separation unloading conical cylinder (2), a water sleeve (20), a main shaft (3), a motor (4), a machine seat (21), a water supplying device (6), an ore concentrate tank (7), a tailing tank (8), a machine frame (9), a V belt wheel (22), an outer cylinder body (19), an unloading device and an automatic control system (5) for controlling operation of the separation unloading conical cylinder (2) and the water volume of the water supplying device (6); a rotating connector (23) is mounted at the lower end of the main shaft (3); the separation unloading conical cylinder (2) is of a circular-table-shaped structure with the large upper portion and the small lower portion, wherein the structure is formed by staggering and overlaying cylindric pieces and circular ring pieces; and the unloading device comprises an inverted trapezoidal blade, 2-5 wedge-shaped scrapers, a flat tray, an ore concentrate discharging pipe, a pinch valve and a machine halt ore discharge pipe. The vertical type centrifugal ore separator used for hematite separation and capable of achieving continuous ore discharge has the advantages that the automatic unloading function is achieved, continuous operation can be conducted, the production capacity is high, power consumption is small, and continuous ore discharging can be conducted; and the pinch valve can timely adjust the productive rate of ore concentrate, and the preferable selecting effect is achieved.

Description

technical field [0001] The invention belongs to a kind of gravity mineral separation equipment, in particular to a vertical centrifugal mineral separation machine, which can be used instead of a water-jacketed automatic centrifugal mineral separation machine to realize continuous ore discharge of the vertical centrifugal mineral separation machine, and is especially suitable for iron tailings. Efficient recovery of iron ore. Background technique [0002] Vertical centrifugal concentrator is a general term for centrifugal concentrators installed vertically on the rotating shaft. The working principle is that under the drive of the motor, the cone cylinder is rotated through the V-belt wheel transmission, and the pulp in the cone cylinder is driven to rotate at a high speed. In the process, based on Particles of different densities are subjected to differences in centrifugal force, and particles of different densities are separated under the action of centrifugal sedimentation...
