Description
Technical field
The utility model relates to a kind of preparation equipment, specifically is that a kind of test is with the little flotation device of pillar microvesicle.
Background technology
The used flotation device great majority of float test are agitation impeller flotator at present, and the float test data of making of agitation impeller flotator has broken away from production reality often, and is not accurate enough, can not instruct coal washing production well.
Summary of the invention
The utility model technical problem to be solved provides a kind of result of the test and tests more accurately with the little flotation device of pillar microvesicle.
Address the above problem, the technical scheme that the utility model adopts is:
A kind of test comprises preprocessor, flotation column, microvesicle generators and mine tailing case with the little flotation device of pillar microvesicle,
Preprocessor comprises a casing, is provided with agitator in the casing, and bottom half is connected with the flotation column middle part through mineral-feeding pipe;
Flotation column comprises a hollow cylinder, and the cylinder top is provided with the concentrate feeder, has the cleaned coal outlet on the concentrate feeder;
Mine tailing case bottom is communicated with the flotation column bottom, and mine tailing case bottom is provided with discharge gate;
The inlet of microvesicle generators is connected with flotation column through pipeline, and pump is housed on the pipeline, and the outlet of microvesicle generators is connected with the flotation column bottom.
In preprocessor, add clear water, agitator adds coal sample the feelings subordinate who constantly stirs, and after the coal sample complete wetting, adds collecting agent and foaming agent, opens the pan feeding valve again, and coal slime gets into flotation column through mineral-feeding pipe.Circulation ore pulp from extract out the flotation column bottom pumps up, and injects microvesicle generators; Suck air and be ground into micro air bubble, in pressure releasing process, separate out a large amount of fine active bubbles subsequently, in pipe, mix; Tilt to spray into the flotation column bottom, form stronger vortex and stir.This moment, the circulation ore pulp of gassiness solid-liquid three-phase act in centrifugal force and buoyancy down, bubble and the gas floc sedimentation of mineralising overflow entering concentrate feeder to center and the top formation froth bed that moves.Non-foam layer is that mine tailing is then discharged through the mine tailing case from flotation column bottom discharging mouth, reaches sorting purposes, utilizes the mine tailing case can regulate the liquid level in the flotation column simultaneously.
The described test of the utility model is accurate with the experimental result that the little flotation device of pillar microvesicle obtains, also have simple in structure, convenience operation.

Fig. 1 is the structural representation of the utility model.
Among the figure, 1-preprocessor, 2-flotation column, 3-microvesicle generators, 4-mine tailing case, 5-agitator, 6-mineral-feeding pipe, 7-concentrate feeder, the outlet of 8-cleaned coal, 9-discharge gate, 10-pump, 11-motor, 12-water tank, 13-fountain head.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
The described a kind of test of the utility model is with the little flotation device of pillar microvesicle; Comprise preprocessor 1, flotation column 2, microvesicle generators 3 and mine tailing case 4; Preprocessor 1 comprises a casing, is provided with agitator 5 in the casing, and bottom half is connected with flotation column 2 middle parts through mineral-feeding pipe 6; Mineral-feeding pipe is positioned at 2/3 high place of cylinder, and agitator 5 is driven by motor 11.Flotation column 2 comprises a hollow cylinder, and the cylinder top is provided with concentrate feeder 7, has cleaned coal outlet 8 on the concentrate feeder 7, and concentrate feeder 7 tops are provided with the fountain head 13 that is connected with water tank 12.The flotation column bottom is provided with the discharge gate of discharging tail coal.Mine tailing case 4 bottoms are communicated with flotation column 2 bottoms, and the inlet that mine tailing case 4 bottoms are provided with discharge gate 9. microvesicle generators 3 is connected with flotation column 2 through pipeline, and pump 10 is housed on the pipeline, and the outlet of microvesicle generators 3 is connected with flotation column 2 bottoms.
In actual production, can make with reference to following technical parameter:
Flotation column column diameter: 200mm
Flotation column height of column: 580mm
Flotation column cylinder capacity: 18L black water
Material size :-0.5mm
Microvesicle generators number: 6
Power of motor: 0.370kw
The test of adopting above parameter is with the little flotation device course of work of pillar microvesicle and points for attention:
1. the clear water that in preprocessor 1, adds 18 liters, agitator 5 (rotating speed can not be too big, otherwise water can overflow) under continuous condition of stirring, adds the coal sample (calculating the weight of coal sample according to desired concn) that weighs up in advance.Coal sample will be added in the periphery of preprocessor, not directly is added on the center, is prone to stifled feeding mouth like this.
2. after coal sample adds agitator 1 fully; Stir and let in two minutes after the coal sample complete wetting, add a certain amount of collecting agent (calculating in advance and the amount of getting) with microsyringe, after one minute; Add foaming agent, the pan feeding valve (can not all open) of slowly outwarding winding after 10 seconds.
3. after adding certain black water in the flotation column, open the valve of coal slurrypump 10 switches and microvesicle generators 3.
4. when black water is filled with flotation column 2 cylinders, regulate mine tailing case 4, make the liquid level in the cylinder keep certain height (froth bed can flow out); Open fountain head; Abundant froth bed flows into concentrate feeder 7 naturally under the bath effect, and is collected in concentrate in the concentrate bucket.With the valve that advances to open mine tailing case 4, mine tailing flows in the collecting vessel.
5. about 7 minutes time; Black water all gets into flotation column 2 in the preprocessor 1, also no longer produces new froth bed in the flotation column 2, explains that most of concentrate has got into concentrate feeder 7; Close the power supply of agitator and pump this moment; Close the valve of microvesicle generators 3, open baiting valve, be collected in mine tailing in the mine tailing bucket.
Whole experiment approximately needs 20 minutes time, and result of the test is:
Little float test account
Coal sample: eastern bent floatation feed coal sample size :-0.5mm coal sample ash content: 23.80 %
Flotation device volume: 18 liters of pulp densities: the preparatory mixing time of 60 grams per liter ore pulps: 2 fens ore pulps and collecting agent time of contact: 2 fens ore pulps and foaming agent time of contact: 1 minute
