Feeding guide plate of novel thickener

Abstract

The invention relates to a feeding guide plate of a novel thickener. The feeding guide plate comprises an umbrella-shaped cylinder, a circular ring and a fixed shaft sleeve; the feeding umbrella-shaped cylinder of the novel thickener is circular truncated cone-shaped and is located at the position which is under a central feeding cylinder of the thickener and is away from the bottom end of the central feeding cylinder by 300-400mm; the umbrella-shaped cylinder is fixed together with a main shaft rake of the thickener by the fixed shaft sleeve, so that ore pulp goes into the thickener in the horizontal direction and flows to the four directions dispersively, and therefore, a stable sedimentation layer can be formed, the efficiency of the thickener is improved, and meanwhile, the cutting-out of the fed ores and the bottom flow is also prevented, the concentration of the bottom flow is increased and the dehydration effect is improved.

Description

technical field [0001] The invention relates to the technical field of solid-liquid separation, in particular to a novel thickener feed deflector. Background technique [0002] Thickener is a commonly used equipment for solid-liquid separation based on gravity sedimentation, and is widely used in the field of metallurgy. It is divided into ordinary thickener and high-efficiency thickener. At present, the method of direct ore feeding is mainly adopted, and the ore slurry is directly fed into the thickener from the central feeding cylinder. This ore feeding method causes the ore flow to rush directly to the settlement area, forming an upward return flow, so that the particles that have just settled are washed up again, causing fine particles to fail to settle, and the high-efficiency thickener is likely to cause damage to the formed flocs. In practical application, problems such as poor thickening effect of the thickener, turbid overflow water and low ore discharge concentra...

AI Technical Summary

Problems solved by technology

This feeding method causes the ore flow to rush directly to the settlement area, forming an upward return flow, so that the particles that have just settled are washed up again, causing fine particles to fail to settle, and the high-efficiency thickener is likely to cause damage to the formed flocs.

In practical application, problems such as poor thickening effect of the thickener, turbid overflow water and low ore discharge concentration are likely to occur, which restrict the further improvement of production efficiency
