Jet-type short-column flotation machine

Abstract

The invention discloses a jet-type short column flotation machine. The jet-type short column flotation machine comprises a flotation column assembly. The upper end of the flotation column is a cylinder, the lower end of the flotation column is a cone, and a concentrate collecting tank, a concentrate converging tank and an outlet are formed in the periphery. An inner conical cylinder and a dispersion plate which are used for reflection and dispersion are arranged inside, a tailing collecting tank is arranged between the inner conical cylinder and an outer conical cylinder, and a secondary circulating collecting port and a circulating pipe are arranged at the lower end. A feeding device is automatically controlled, and a feeding pipe is installed in the center of the flotation column cylinder from bottom to top and connected to an ore pulp dispersing bag. A jet nozzle, an air suction mechanism and a diffusion port are installed in an ore pulp jet device, a tailing confluence bin is arranged at the bottom of the outer conical barrel, a gate valve and a tailing discharge port are formed in a tailing barrel, and a chemical adding mechanism and two defoaming devices are arranged. The jet-type short column flotation machine is mainly used for flotation of coal slime and nonferrous ores, and has the advantages of sufficient ore pulp mineralization, high separation efficiency, low flotation concentrate ash content, high control precision, stable operation and low operation cost due to no operation parts.

Description

technical field [0001] The invention relates to the technical field of flotation machines, in particular to a jet-type short-column flotation machine. Background technique [0002] Flotation machines are mainly used for separation and treatment of coal, ferrous and non-ferrous metal minerals, and are widely used in coal slime flotation, non-ferrous ore flotation and industrial sewage treatment, especially tailings. Flotation machines are usually divided into three categories: mechanical agitation flotation machines, inflatable agitation flotation machines and inflatable flotation machines. [0003] The aeration and stirring of the pulp in the mechanical agitation flotation machine are completed by a mechanical agitation device composed of an impeller and a stator. It belongs to the external air self-priming flotation machine. Inhalation of air near stirring device. The characteristics of this type of flotation machine are that it can self-absorb air and ore pulp, it is eas...

AI Technical Summary

Problems solved by technology

However, due to the lack of stirring and strengthening mineralization process of the flotation machine, the mineralization intensity of the flotation column is relatively weak. Therefore, the flotation column generally increases the length of the mineralized area by increasing the column height, so that the The height of the column is generally about 10 meters, but the recovery rate is still lower than that of the flotation machine, and the volume is huge

In response to this problem, many scholars have designed some new flotation columns, which enhanced the mineralization effect to a certain extent, but none of them solved the fundamental problem. At present, the recovery rate of flotation columns in the flotation of metal minerals is still not as good as that of machine selection
