Background

The equipment on the traditional mechanical stirring flotation machine in the industries of oil refining, petrochemical industry, metallurgy, mining industry and the like is not beneficial to the concentration of ore particles because the violent vibration is generated by the mechanical stirring, particularly, the fine ore particles are more difficult to recover, the recovery rate is difficult to improve, and the existing mechanical flotation machine can not meet the requirement.

An important feature of the flotation column is its froth flushing system by which the auxiliary means of froth flushing removes unwanted impurities from the flotation froth, and the flushing water added from the top of the column is filtered through the froth zone to displace process water and trapped particles of the bubbles, and in addition, the froth flushing water acts to stabilize the froth by dividing the bubbles into a round and strong packed bed. However, excessive washing water may cause the froth to break, thereby reducing the production capacity, and also cause an unstable froth, so that it is necessary to reduce the flow rate of washing water, thereby greatly improving the recovery rate and the grade of the flotated product.

The utility model discloses a utility model with application number 201720385607.5 discloses a flotation column foam liquid level sprays washing unit, it includes the frame, the frame top is provided with the inlet tube, the frame below is provided with washs the water distributor, it is provided with the water inlet to wash the water distributor top, the delivery port position of inlet tube is corresponding with the water inlet position of wasing the water distributor, it is provided with a plurality of showers to wash the water distributor around, and the mouth that sprays through a plurality of showers covers the foam area of whole flotation column, its simple structure, and reasonable in design can reduce the flow rate of wasing water to improve the grade of rate of recovery and flotation article greatly. But above-mentioned washing unit sprays the mouth through a plurality of shower and covers the foam area of whole flotation column, and its homogeneity that sprays washs is relatively poor, can't effectively guarantee final cleaning performance.
