Self-rotation type air flotation column and air flotation beneficiation method
Technical field: The invention relates to a self-rotating the gas floats the column and the flotation separation method. Background technology: Existing graphite dressing the flotation of medicine, medicament flotation of the following shortcomings: 1, high cost: of a ton of graphite ore concentrate each selected reagent-consuming 150---280 cost $. 2, environmental pollution: beneficiation waste water recovery and use less, most of the discharged into the river, cause pollution. 3, slag can no longer utilize: dressing drog adhered to because the chemicals, drog pollution is no longer using. Air storage but also cause environmental pollution. 4, the graphite products selected are restricted to use: with a medicament selected graphite product can not directly utilize the high-level acieries. 5, because the production process is too long, it is very difficult to produce the high-quality product. The content of the invention is: The purpose of this invention is to offer a kind of self-rotating the gas floats the column and the flotation separation method. The above object is realized by the following technical scheme: A self-rotating the gas floats the column , its composition includes: a group of high voltage ore, the high-pressure of the slurry pipe is installed on the cylinder, the cylinder is provided with a group of fine small hole with self-priming port, the lower end of the cylinder is provided with a group of high-pressure air inlet pipe, the high pressure air inlet pipe is the end of the air outlet of the fine holes, on the cylinder is provided with a bracket, a hollow shaft mounted on the two ends of the bracket and on the bearings of the cylinder, the hollow shaft is provided with a group of rotary wheel, the hollow of the rotating wheel with the moulds is communicated with the hollow shaft, the hollow of the capillary temperature, the high-pressure corresponding to the injection direction of the ore of the side end of the hollow the moulds. The rotary the gas floats the column , the hollow the moulds with the triangular shaped stirring plate is connected with, the upper end of the cylinder is provided with an overflow outlet, the said cylinder is provided with a slag outlet at the lower end. A self-rotating the gas floats the column the air separation method, high voltage ore slurry is injected into the air column in the hollow impact the temperature, pressure of the rotation of the rotary wheel, a hollow wheel when in rotation to form a negative temperature, the intake air from the outside, and the gas in the pulp homogenizing diffusum, form micro-bubbles, formed in the top part of the foam layer, the foam layer to reach the height of the baffle, the foam overflow, adhered to the foam be charged of the selected other thing, tailings discharged from the lower part. Beneficial effects: The invention adopts the air-float also called gas flotation, the principle is to make the water to produce a large number of micro-bubble, so as to form water, gas and selecting the three-phase mixture, in interfacial tension, bubble rising buoyancy and hydrostatic pressure difference and the like under the combined action of the striation, to promote fine bubbles in the sorting object. The adherend smaller than the density of water and floating up to the water surface, is selected so as to make the pulp can be separated from other objects. This invention has high processing capacity, the characteristic of the high treatment effect; compared with the common flotation method has the advantages of saving in energy and pharmaceutical, environmental protection and high efficiency, the advantages of low operation cost, suitable for modern enterprise energy-saving, environmental protection, the consumption is reduced, the requirement of efficiency. The invention saves electricity, and medicine, small occupied area, high efficiency, beneficiation waste water can be completely recycled, save a great deal of cost. The present invention is pollution-free, no waste water discharge, discharge of slag can be recycled. The Figure illustrates: Attached Figure 1 is a structure diagram of the invention. Attached Figure 2 is the relative position of the high voltage ore a schematic diagram of the invention. Attached Figure 3 is a structure diagram of the hollow the moulds of this invention.
