Abstract
The utility model provides a fine coal slime sorting facilities, optimum being used for is selected separately fine coal slime under the pressurization environment. Sorting facilities includes that CO2 storage tank, CO2 force (forcing) pump, CO2 delivery pump, coal slime water storage tank, the mixed agitator of pressurization, suspension delivery pump, pressurization separator column, concentrate decompression jar, tailing decompression jar, concentrate collection device, tailing collection device, CO2 retrieve the jar. During the use, the pressurization adds the coal slime water of treating the sorting in advance in mixing the agitator to give CO2, stir the mixture, then the coal slime water and the CO2 mixtures that will mix after the stirring with the suspension delivery pump give the pressurization separator column, give CO2 from the lower part with the CO2 delivery pump simultaneously, and low grey clean coal wadding group is transferred to the CO2 looks on upper strata by the aqueous phase to get into concentrate collection device through the overflow chamber of pressurization separator column, during the aqueous phase of separator column lower floor is then stayed to the mineral of high ash, and in discharging tail coal collection device, thereby realize the purpose of coal and mineral separation.
Description
Technical field
The utility model relates to a kind of slime separation equipment, especially a kind of be applicable to sorting fall ash fine coal slime screening installation.
Technical background
Along with the raising of coal selecting and purchasing mechanization degree, in raw coal, the content of fine coal slime increases year by year.At present, in coal preparation plant, the process of black water is mainly dewatered by mechanism filter-pressing, and final coal slime product moisture content is high, and coal slime carries phenomenon secretly seriously, has a strong impact on coal preparation technology economic benefit.Existing slime separation mainly adopts floatation process, and it is to the poor selectivity of difficult-to-float coal and aid for Micro-fine Coal Slurry Dewatering, and the moisture of floatation clean coal product is high.Therefore, a kind of new and effective fine coal slime sorting processing technology is developed significant to the sorting upgrading of coal slime, clean utilization.
Summary of the invention
The purpose of this utility model is the deficiency overcoming existing slime separation technical matters, provides the equipment of the fine coal slime sorting that a kind of separative efficiency is high, moisture of cleaned coal is low.
For achieving the above object: fine coal slime screening installation of the present utility model, comprises CO
