Problems solved by technology

First of all, the uniformity of the gas in the aerator in the flotation column will be affected by the size of the cross-section of the flotation column. If the cross-sectional area is small, the gas dispersion will be high and easy to control. The range of the ejected gas is limited so that the gas cannot be evenly dispersed on the entire cross-section of the column; secondly, the flotation column is generally 8-15m high, and a certain mechanical strength should be guaranteed in the direction of the column. Too much quantity distributed in the circumferential direction, too dense will affect the strength on the circumference of the wall of the flotation column and it will be difficult to check and maintain
The degree of gas dispersion in the flotation column directly affects the process performance of the equipment. It is necessary to ensure that the gas charged into the flotation column from the aerator can be evenly dispersed on the cross section of the column, and at the same time, the flotation column has sufficient mechanical strength and convenience. Inflator inspection and maintenance conditions, this kind of inflator configuration obviously has limitations

Embodiment Construction

[0017] The flotation column of the present invention comprises a spray water assembly, an ore feeding system, a column body assembly and a tailings system, and the flotation column also comprises a conical column bottom of the flotation column and a plurality of flotation column aerators (see Figure 4 ), the conical column bottom 8 of the flotation column is located in the lower part of the flotation column, the conical bottom of the flotation column conical column bottom 8 is funnel-shaped downwards, and the upper edge is welded to the inner wall of the column assembly. The conical column bottom 8 of the flotation column provides ample space for the aerator configuration of the flotation column, ensuring that the aerator can be distributed in multiple circles at different heights in the space; and can promote the smooth discharge of the ore slurry in the flotation column to prevent Mineral particles accumulate and sink.

Abstract

The invention discloses a flotation column which comprises a spraying water component, a feeding system, a column component and a gangue system, and further comprises a taper column bottom of the flotation column and a plurality of flotation column aerators, wherein the taper column bottom of the flotation column is located on the lower part inside the flotation column; the plurality of flotation column aerators are installed on the taper column bottom; the flotation column aerators are vertically installed at different height positions of the taper column bottom of the flotation column and are distributed along a plurality of circumferences of the taper column bottom of the flotation column. The flotation column aerators are distributed on the plurality of circumferences at different height positions of the taper column bottom of the flotation column, so that the distribution quantity of the aerators in a cross section of a column body is controlled according to the needed air flow and the size of the cross section of the flotation column of a selected process, dispersion degree of gas injected in the column is high; and the flotation column aerators are longer in service lives and stable in work performance under protection of wear-resisting steel tubes.

Description

technical field [0001] The invention relates to the field of mineral processing, in particular to a flotation column. Background technique [0002] Flotation column is a kind of mineral processing equipment, which is widely used in the separation of non-ferrous metals, ferrous metals and non-metallic minerals. see figure 1 , The flotation column usually consists of a spray water assembly 1, an ore feeding system 2, a column assembly 3, an aeration system 4 and a tailings system 5. When the direct air flotation column is working, the high-pressure air (0.5-0.7MPa) from the air compressor is sprayed into the flotation column at high speed through the inflation system installed at the lower part of the flotation column, and the pulp in the flotation column is sheared Under the action of cutting, a large number of fine air bubbles are generated, and the air bubbles rise slowly from the bottom of the column; the ore slurry is fed from the 2 / 3 height of the column, and after bei...
