Flotation column

Abstract

The invention discloses a flotation column which comprises a flotation column body (5) and a bubble generator (4), wherein one end of a spiral pipeline (3) is connected with a feed opening (1), an air inlet (2) is arranged beside the feed opening (1), the other end of the spiral pipeline (3) is connected with the upper part of the flotation column body (5), the bubble generator (4) is connected with the lower end of the flotation column body (5) by adopting an external inserting mode, and both the air inlet (2) and the bubble generator (4) are connected with an air pump (6). An ore slurry can be fully sheared and mineralized by the flotation column by utilizing the spiral pipeline, the generated bubbles are superfine and have better dispersion effect, and the flotation column has the characteristics of simple structure, stable operation, difficult blockage, good mineralization effect and the like, can be suitable for floating a plurality of metals or nonmetals, is a new generation of high-efficiency flotation column and can be applied to multiple fields of metal mines, coal, environmental protection and the like.

Description

technical field [0001] The invention relates to a flotation column, in particular to a flotation column with a spiral pipeline and a magnetic bubble generator. Background technique [0002] At present, the general flotation column uses the bubbles generated by the bubble generator to mineralize inside the flotation column. In this way, the nature and dispersion of the bubbles generated by the bubble generator determine the good mineralization effect inside the flotation column. Bad, it is easy to cause uneven mineralization and insufficient flotation time. However, for the mineralization at the downcomer, the flotation column using a self-priming bubble generator needs the negative pressure generated by the high-speed slurry due to the inhaled air mineralization process, so the energy consumption on the feed pump is relatively large, which restricts the bottleneck more obvious. The bubble generator in the flotation column is widely used in metal and non-metal mines, metall...

AI Technical Summary

Problems solved by technology

There are many kinds of bubble generators currently in use. The generation of bubbles is mainly realized by mechanical stirring or porous material inflators. However, these bubble generators have loose structures, high manufacturing costs, troublesome disassembly and maintenance, and difficult to control the bubbles. and other shortcomings

[0003] Most of the flotation column processes in our country use bubble generators to generate bubbles, and most of the bubble generators are built-in, and these bubble generators inevitably come into contact with gas, liquid, solid, etc. of different particle sizes inside the flotation column. Uniform multi-phase mixture, so blockage will inevitably occur at the outlet of the generator, and because of its troublesome disassembly and maintenance, it will have a negative impact on technical and economic indicators
