Abstract

The invention relates to the technical field of thickeners in a mine mineral processing process and particularly relates to a protection device and method for a rotary supporting bearing and a driving motor of a thickener. The protection device comprises a primary driving circuit of the thickener, a slide wire and a current collector, and is composed of a three-phase current transformer, a driving motor protector, a tripping and sound-light alarming device and an RS485 / RS232 converter which are arranged among the driving circuit of the thickener, the slide wire and the current collector in sequence; a first circuit breaker with a shunt release is arranged among the slide wire, the current collector and a motor or a second circuit breaker with the other shunt release is arranged between the driving circuit of the thickener and the three-phase current transformer; and the RS485 / RS232 converter is connected with an upper computer and a display. The protection method comprises overcurrent protection of the driving motor, and bad contact and phase loss protection of the driving motor. The protection device and method for the rotary supporting bearing and the driving motor of the thickener have high protection precision, accurate movement, strong anti-interference performance and complete functions, and can effectively protect the rotary bearing of the thickener.

Description

technical field [0001] The invention relates to the technical field of concentrators in the mine beneficiation process, in particular to a protection device and method for the rotary support bearing and the driving motor of the concentrator. Background technique [0002] At present, in the mine beneficiation process, thickeners are usually used for the concentration of ore pulp. The fixed parts of the basic structure of the concentrator include: incoming ore chute, lower mine hole, center column, slip ring, and slewing support bearing; the moving parts include: rake frame, collector, drive motor, reducer, etc. The main function of the thickener is to concentrate the low-concentration pulp, that is, to inject the pulp with a certain concentration into the thickener, and to generate a high-concentration pulp through gravity settlement and rake collection to meet the requirements of the next process. The basic principle of the thickener design is to select the size of the thic...
