Thickener underflow conveying and maintenance system

Abstract

The invention relates to a thickener underflow conveying and maintenance system. The thickener underflow conveying and maintenance system comprises a thickener and a maintenance system, wherein an underflow discharging opening is formed in the bottom of the thickener, an underflow pump is mounted in an underflow chamber below the thickener, the underflow discharging opening is communicated with the underflow pump through an underflow pump inlet pipeline, a gate valve is arranged on the underflow pump inlet pipeline, the maintenance system comprises an electric hoist, a flat-bed trailer and a windlass, an electric hoist track is mounted at the top of the underflow chamber corresponding to the position of the underflow pump, the electric hoist is mounted on the electric hoist track, the windlass is arranged on the ground and is connected with the flat-bed trailer placed in the underflow chamber through a steel wire rope, and the flat-bed trailer is drawn to the ground through the windlass. The thickener underflow conveying and maintenance system is applicable to the field of thickener underflow conveying and maintenance, particularly occasions with high operating rate requirements, stable index requirements and high safety requirements. The system is high in production flexibility, stable in index, high in safety, easy to service and maintain, high in degree of automation and small in investment.

Description

Technical field: [0001] The invention relates to the technical field of thickener underflow conveying and maintenance, in particular to a thickener underflow conveying and maintenance system. Background technique: [0002] Thickener is a solid-liquid separation equipment based on gravity sedimentation, which is widely used in hydrometallurgy, mineral processing plants, chemical plants and other places that require solid-liquid enrichment and separation. [0003] The clarified liquid (overflow) generated in the upper part of the thickener is discharged from the top annular chute, and the generated underflow (enriched in solid particles) is usually transported out by a pipeline connection slurry pump. [0004] The thickener plays an irreplaceable role in the beneficiation plant. Its main function is to concentrate and dehydrate to provide conditions for the next process. Once the thickener breaks down and needs to be shut down, it will not be able to receive materials from th...

AI Technical Summary

Problems solved by technology

The bottom flow pumping station usually has a depth of 10-15m underground, and the construction is difficult and costly, which greatly increases the cost of the entire thickener and increases the investment of the entire concentrator
