Compound inflation multi-column-body combined type flotation equipment

Abstract

The invention discloses compound inflation multi-column-body combined type flotation equipment. The compound inflation multi-column-body combined type flotation equipment comprises a feeding system, a flotation column and a discharging system. The flotation column comprises an upper column body and at least two lower column bodies which are communicated; the diameter of the upper column body is greater than the sum of the diameters of the lower column bodies; inflation devices are arranged at the bottom of each lower column body and inside a feeding pipe. The flotation adaptability of the flotation equipment to different kinds of ores is high; the flotation efficiency is high, and the procedure is simplified; especially, the recycling effect of fine-grained minerals or minerals with large floatability difference is outstanding; the diameter of the column is not restricted by the self features of the flotation column; energy consumption is low, the reagent dosage is lower than that of a traditional flotation machine, and the production cost is reduced.

Description

technical field [0001] The invention relates to a composite inflatable multi-column combined flotation device, which belongs to the technical field of flotation devices. Background technique [0002] With the development of the national economy, the extensive resource development model has gradually restricted the resource recovery rate and resource recycling rate. The flotation column is more and more widely used in the field of flotation technology because of its high selectivity for fine materials, such as the domestic cyclone-static micro-bubble flotation column, jet flotation Column and Australia's Jameson flotation column, Canada's CPT flotation column, etc. [0003] Now the general flotation column is a slender cylindrical structure, the general column height is 9-15m, the diameter is 0.5-3.0m, and the section is rectangular or circular. For flotation columns with a diameter of more than 2m, more rectifying plates are installed in the column along the axial directio...

AI Technical Summary

Problems solved by technology

These flotation columns have the problem that the concentrate grade and recovery rate cannot achieve the best results at the same time, and for the flotation of minerals with large differences in floatability or uneven distribution of thickness, a combined process of flotation columns and flotation machines is required Or the flotation column can achieve the ideal beneficiation index through multiple separation processes. At the same time, it is restricted by the characteristics of the flotation column, so that the column diameter of the flotation column should not be too large, generally within 6m, which will lead to a single flotation column processing power is limited
