Combined type centrifugal ore separator directly driven by permanent magnetic synchronous motor

Abstract

The invention discloses a combined type centrifugal ore separator directly driven by a permanent magnetic synchronous motor. The centrifugal ore separator comprises a housing, an ore feeding opening,an outer sleeve, an inner sleeve a tailing discharging opening and a rotating mechanism; the inner sleeve and the outer sleeve are coaxial and the axis is provided with a rotating shaft; the rotatingmechanism is connected with the rotating shaft to drive the inner sleeve and the outer sleeve to rotate about the axis; the rotating mechanism is a permanent magnetic synchronous motor; the permanentmagnetic synchronous motor comprises a rotor component and a stator component; the rotor component comprises a rotor and permanent magnets, wherein the permanent magnets are uniformly arranged on therotor in the circumferential direction and round the axis; the rotor is arranged on the rotating shaft in a sleeving manner; the stator component and the rotor component are arranged oppositely; the stator component is formed by combining at least two stator units which are each of a fan-shaped block structure; each stator unit comprises a stator core and a stator winding which is coiled on the stator core. The centrifugal ore separator disclosed by the invention is high in transmission efficiency, low in noise and large in torque.

Description

technical field [0001] The invention belongs to the technical field of centrifugal separation, in particular to a centrifugal concentrator directly driven by a combined permanent magnet synchronous motor. Background technique [0002] Centrifugal separation is an improved gravity beneficiation technology. Since the rotational motion can produce a centrifugal acceleration tens, hundreds, or even thousands of times greater than the earth's gravitational acceleration, the centrifugal separation technology using rotational motion has advantages that cannot be compared with ordinary gravity beneficiation. Superior performance, with high separation efficiency, large processing capacity, high recovery rate, strong adaptability and many other advantages and benefits. Centrifugal concentrators, centrifugal separation equipment using rotary motion, can be divided into several categories according to the characteristics of vertical / horizontal, with / without recoil water, intermittent di...

AI Technical Summary

Problems solved by technology

The transmission mechanism is an intermediate device, such as a reduction box, a pulley, etc., and friction pairs are added during work, resulting in low transmission efficiency and high noise

[0004] The drive power source mainly adopts the combination of two-speed motor main drive and hydraulic motor auxiliary drive mode or variable frequency motor drive mode. The above-mentioned two-speed motor main drive and hydraulic motor auxiliary drive mode has the following disadvantages: 1. It cannot continuously adjust the speed ;2. The structure is complex and the geological adaptability is poor; 3. The transmission efficiency is low, and the failure rate is high, which affects the speed of mineral processing; 4. The hydraulic motor and the motor cannot be driven at the same time; 5. The response speed is slow and the energy consumption is high.

[0005] In addition, the existing centrifugal concentrator consumes a lot of water during the beneficiation process, and usually needs to be equipped with backwash water and motor cooling water separately, which is not environmentally friendly and has poor mechanical stability, which affects the processing capacity per unit area to a certain extent and production efficiency
