Flotation column special for floating fine flake graphite

Abstract

The invention relates to a flotation column special for floating fine flake graphite, belonging to the technical field of graphite flotation; the flotation column disclosed by the invention is mainly composed of a mixing device, a static mineralizing machine, an upper column body, a scraping device, a distributor, a lower column body, a gangue discharging device, a middle column body, a dosing device and a PLC (programmable logic controller) control case; the mixing device is composed of a mixing pipe, a nozzle, a throat pipe and an expanding pipe; the static mineralizing machine is composed of a case body, a variable-diameter amplifier, a baffle board, an uniform distribution board and a discharging pipe; the upper column body is composed of an upper barrel body, a finished ore groove and a static charging device; the scraping device is composed of a motor, a decelerator, an output shaft and a scraper; and the distributor is composed of a distributing pipe, an electric valve, an electric contact pressure gauge, a circular pump and a micro-bubble generator. According to the invention, the flotation column has the advantages of good raw ore and medicament mineralizing effect, small charging kinetic energy, large cyclone force field, good flotation effect and large treatment quantity.

Description

Technical field [0001] The invention relates to a special flotation column for fine scale graphite flotation, which belongs to the technical field of graphite flotation. Background technique [0002] Graphite is a very important non-metallic mineral material. It has excellent properties such as high temperature resistance, thermal shock resistance, high chemical stability, thermal conductivity and lubricity, so it is widely used in machinery, metallurgy, refractory materials, chemical industry, aviation, etc. Aerospace and other industrial sectors. With the development of science and technology, graphite consumption is increasing worldwide, and people are no longer satisfied with the demand for large flake graphite, and the development and utilization of fine flake graphite are being paid attention to. [0003] At present, the commonly used purification method of fine flake graphite is flotation, and the flotation equipment used is: mechanical agitation flotation machine, i...

AI Technical Summary

Problems solved by technology

The main disadvantages are as follows: 1) The mineralization effect of raw ore and chemicals is poor; 2) The kinetic energy of feeding is large, the disorder is serious, some bubbles are easy to burst, the flotation effect is poor, and the processing capacity is small

If the flotation column is directly used for flotation of graphite, there are the following problems: 1) the mineralization effect of the raw ore and the reagent is poor; 2) the kinetic energy of the feed is large, the disorder is serious, some bubbles are easy to burst, the flotation effect is poor, and the processing capacity is small ; 3) The flotation concentrate foam cannot be discharged in time, and the flotation efficiency is low; 4) The swirling force field at the bottom of the lower column is small, and the mineralization effect of the pulp and the chemical in the lower column is poor; 4) The dosage of the chemical is large, and the operating cost is high
