Description
Technical field
This utility model relates to a kind of flotation CaO medicament that improves and adds the device of stability, belongs to mechanical field.
Background technology
The reverse floatation process flow process that Lanxian County mining company of Taiyuan Iron and Steel Co. group is swept by a thick essence three, adds collecting agent, NaOH, corn starch and tetra-kinds of medicaments of CaO in batches and mill magnetic is come ore deposit carries out flotation, and final production goes out the fine iron breeze of concentrate grade TFe >=65%.
CaO is as quartz (SiO2) activator, improving quartz surfaces hydrophobicity, promote quartz and the interaction of collecting agent and carry in tail etc. drops in essence, all playing vital effect, so in Floating Production Process, it is necessary to ensure that the stable interpolation of CaO.
CaO adding technology flow process is: first with delivery pump, the lime cream that concentration is 2% prepared in preparation tank (∮ 10m × 11m) is transported in CaO agitator tank (∮ 5m × 5m) stand-by, when needing to add medicament, start interpolation pump and CaO is delivered to thick, selected chemical feeding points.
Add pump to the duct length roughly selecting chemical feeding points be about 20 meters, duct length to selected chemical feeding points be about 130 meters.There is problems in that medicament can not stably add (flow can not control or occur cutout), had a strong impact on stablizing of technological process, deteriorated floatation indicators.
(1) lime cream according to enter floating ore deposit amount number add, be variable because entering floating ore deposit amount, so lime cream addition is also changing.Due in lime cream Calx [Ca(OH)2] it is insoluble in water, easy occluding device facility, therefore cannot use dosing pump and effusion meter, it is impossible to adjust in time and control addition, causing accurately adding.
(2) adding pipeline length and the many characteristics being insoluble in water with Calx in lime cream of elbow due to medicament, cause medicament interpolation pipeline very easily to block and the pipe-dredging time is longer, cause that medicament stops, impact produces.
Summary of the invention
This utility model provides a kind of flotation CaO medicament that improves to add the device of stability, can ensure that the accurate stable of CaO medicament adds.
The technical solution adopted in the utility model is: a kind of flotation CaO medicament that improves adds the device of stability, including adding tank, adds tank and is arranged on the top roughly selecting agitator tank and selected agitator tank；Adding tank arrival end and connect CaO discharge nozzle, CaO discharge nozzle adds pump by CaO and connects CaO agitator tank；CaO discharge nozzle inserts and adds pot bottom, and interpolation tank side is arranged over reflux line and leads to CaO agitator tank；Add pot bottom and roughly select agitator tank by roughly selecting the connection of chemical feeding points outlet, be arranged over selected chemical feeding points outlet roughly selecting chemical feeding points outlet, add tank and connect selected agitator tank by selected chemical feeding points outlet；Each outlet arranges valve.
In such scheme, CaO agitator tank is installed a liquidometer, calculates thick, selected reagent consumption amount according to the liquid level difference in the agitator tank unit interval.
In such scheme, add an exhaust-valve adding pot bottom, during system overhaul, clear up deposit in tank.
This utility model is provided above adding tank at flowsheet of slurry agitation groove (roughly selecting chemical feeding points), roughly selects and realizes dosing nearby.Being in a high position owing to adding tank, medicament can flow automatically, and pharmaceutical pipeline shortens, elbow reduces, and medicament adds pipeline and is not easily blocked.
The beneficial effects of the utility model:
(1) ensure that the accurate stable of CaO medicament adds；
(2) prevent CaO medicament from adding line clogging；
(3) eliminate the impact on flotation aggregative indicator when CaO medicament can not stably add, stabilize concentrate grade, improve metal recovery rate.
Below in conjunction with drawings and Examples, this utility model is described further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 for adding tank, and 2 for roughly selecting agitator tank, and 3 is selected agitator tank, and 4 is CaO discharge nozzle, and 5 add pump for CaO, and 6 is CaO agitator tank, and 7 is reflux line, and 8 for roughly selecting chemical feeding points outlet, and 9 is selected chemical feeding points outlet, and 10 is valve, and 11 is liquidometer.
Detailed description of the invention
Embodiment:
As it is shown in figure 1, a kind of flotation CaO medicament that improves adds the device of stability, including adding tank 1, add tank 1 and be arranged on the top roughly selecting agitator tank 2 and selected agitator tank 3；Add tank 1 arrival end connection CaO discharge nozzle 4, CaO discharge nozzle 4 and connect CaO agitator tank 6 by CaO interpolation pump 5；CaO discharge nozzle 4 inserts and adds bottom tank 1, and interpolation tank 1 side is arranged over reflux line 7 and leads to CaO agitator tank 6；Pass through to roughly select chemical feeding points outlet 8 connection bottom interpolation tank 1 and roughly select agitator tank 2, be arranged over selected chemical feeding points outlet 9 roughly selecting chemical feeding points outlet 8, add tank 1 and connect selected agitator tank 3 by selected chemical feeding points outlet 9；Each outlet arranges valve 10.
Concrete manufacture method is:
1, add tank one fabricated above of flowsheet of slurry agitation groove (roughly selecting chemical feeding points), roughly select and realize dosing nearby.Being in a high position owing to adding tank, medicament can flow automatically, and pharmaceutical pipeline shortens, elbow reduces, and medicament adds pipeline and is not easily blocked.
2, CaO adds the discharge nozzle of pump to reach interpolation tank bottoms from adding tank top, utilizes and adds delivery side of pump pressure, the medicament added in tank is stirred, in case medicament layering, density unevenness.
3, CaO adds pump is continuous operation, abundant to ensure to add dose in tank.Adding tank top, a piece return duct is installed, makes medicament can flow back into agitator tank in time, it is to avoid overflow medicine.
4, a liquidometer 11 is installed on CaO agitator tank, calculates thick, selected reagent consumption amount according to the liquid level difference in the agitator tank unit interval.Weld dosing outlet thick, selected and valve adding below the tank backflow mouth of pipe, control flow by adjusting valve opening, reach accurately to add the purpose of pharmaceutical quantities.
