Multi-section atomization regent feeding equipment

Abstract

The invention discloses multi-section atomization regent feeding equipment which comprises an ore feeding part, a drum part and an ore discharging part. The ore feeding part is connected with the upper end of the drum part through a flange. The lower end of the drum is connected with the ore discharging part through a flange. A plurality of ore pulp mixing parts are distributed on the inner wall of the drum part from top to bottom and each comprise an atomization spray nozzle device and an ore separation sieve plate. The ore separation sieve plates are transversely arranged in the drum part. The atomization spray nozzle devices are arranged above the ore separation sieve plates. Filling medium sets are arranged between the atomization spray nozzle devices and the ore separation sieve plates and arranged on the ore separation sieve plates. Multi-section floatation regent feeding and pulp conditioning are achieved when ore pulp passes through the equipment, the regent feeding effect and regent feeding efficiency are improved, the pulp conditioning time is shortened, the floatation index is increased, the regent dosage is decreased, the space utilization rate of a workshop is increased, and the multi-section atomization regent feeding equipment is provided with few movement parts, and is low in energy consumption and few in fault point.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a multi-stage atomization drug delivery equipment. Background technique [0002] With the continuous efforts of beneficiation workers, new beneficiation technologies and new beneficiation processes continue to appear, but foam flotation still plays an important role in the separation of coal mines, phosphate rocks and non-ferrous ores. Stirring in the flotation process is a part with high energy consumption. There are many factors affecting flotation, and the main influencing factor is the interaction between reagents and minerals. For inorganic chemicals, the dispersion and slurry effect can be achieved very quickly by stirring, but for organic chemicals, the water solubility is generally poor, and strong stirring is often used to achieve rapid dispersion of chemicals. On the one hand, it will increase the energy consumption of the flotation process, on the other han...

AI Technical Summary

Problems solved by technology

The flotation column itself does not have a stirring effect, so external stirring is necessary to increase the energy consumption of the flotation process. Although the flotation cell has its own stirring effect, for the chemicals with poor organic water solubility, only the stirring effect of the stirring tank makes the chemicals Dispersion is beneficial to improve the flotation index to a certain extent, but it cannot make the agent fully interact with the mineral surface to form a hydrophobic film, which affects the amount of particles carried by the foam
