Detailed description of the invention
Below the utility model is further elaborated, but protection domain of the present utility model is not limited to the scope of following described detailed description of the invention.
A kind of method improving vertical sand warehouse concentration of emission stability, mortar self-diluting device 3 is added at warehouse 1 top, be connected with tailings pipe 2, pan feeding well 4 is fixed on warehouse 1 top center, polyacrylamide solution pipe 5 is separately fixed in self-diluting device 3 and pan feeding well 4, fixed shear circulation pump 6 bottom warehouse 1, shear circulation pump 6 to be connected with circulating line 8 and discharge tube 9, electric change valve 7 realizes the switching between circulating line 8 and discharge tube 9, in circulating line 8 top access warehouse 1, as shown in Figure 1.Described warehouse 1, is mainly used in storage and the pulping of last mortar, and warehouse column diameter scope is 8 ~ 20m, and altitude range is 15 ~ 25m, and cone angle scope is 45 ° ~ 60 °.Described tailings pipe 2, mainly for delivery of last mortar, controls flow and flow velocity, therefore the caliber scope 150mm ~ 250mm of last mortar.Described self-diluting device 3, be mainly used in diluting last mortar, because pulp consistency is high, fully cannot react with polyacrylamide solution, affect effect of settling, this device uses hydrocone type principle, utilize tailings pipe residual head, suck concentrator top primary water by high flow rate mortar in mortar pipe, can effectively reduce last mortar concentration, polyacrylamide solution is fully mixed with last mortar.Described pan feeding well 4, be mainly used in providing last mortar and the well-mixed space of polyacrylamide solution, diameter range is 2 ~ 5m, and altitude range is 3 ~ 7m.Described polyacrylamide solution pipe 5, mainly for delivery of polyacrylamide solution, for making polyacrylamide solution fully mix, arranging different polyacrylamide solutions and adding point, adding quantity 3 ~ 10.Described shearing circulation pump 6 and circulating line 8, be mainly used in bottom mortar circulation, ensures that bottom slip is in fluidization all the time, prevent material from occurring hardening, stablize mud layer height in sand storehouse, make pulp density and flow bottom sand storehouse be in stable state.Described electric change valve 7, realizes the switching between circulating line 8 and discharge tube 9, during filling, by valve transfer to discharge mode, is switched to circulation mode during not filling.
The embody rule example of this device is described in detail in detail below.
Certain ore deposit adopts vertical sand warehouse process crude tailings, sand storehouse diameter 9m, height of column 21m, cone height 7m, and free factory last mortar is condensed into high concentration last mortar in the future, and be mixed with into high concentration ground paste with cement, Water Quenching Slag, self-flowing pastefill is to stope.In process of production, often occur that underflow puts the problem such as sand difficulty, mud layer height, underflow density and instability of flow, overflow water muddiness, normal operation is produced in impact.For this reason, have employed many kinds of measures, comprise measures such as adding nozzle increase fluidization, effect is still not obvious.After fully analyzing the ropy reason of vertical sand warehouse pulping, mainly natural drainage of tailings effect of settling is poor to think the reason occurring above problem, and bottom last mortar presents heterogeneous body fluidization.And self-diluting device, polyacrylamide solution adding set, self-circulating device are set in vertical sand warehouse, can make that sand storehouse mud layer is highly stable, bottom mortar fluidization, pulping quality is greatly improved, specific as follows:
1) carrying out free factory concentration is 25% ~ 30%, flow 100m
3the last mortar of/h, is delivered in pan feeding well 4 through tailings pipe 2, Tailings Slurry on road through self-diluting device 3 time, by below last mortar concentration dilution to 15%, controlled polyacrylamide solution flow 20m
3/ h, concentration of polyacrylamide solution is 0.5 ‰, fully mixes with last mortar, reaches ideal flocculating setting effect.In the process, not discharge bottom warehouse 1, also without the need to being circulated by circulating line 8.
2) process last mortar is after 32 hours continuously, and in warehouse 1, last mortar mud layer height reaches 8m, and now open and shear circulation pump 6, record pulp consistency by densimeter and reach 75%, electromagnetic flowmeter records flow 20 ~ 50m
3/ h, mobility is poor and unstable, increases and shears circulation pump power to 100%.
3) shear circulation pump 6 peak power after 30 hours from opening, underflow density remains on 67% ~ 70% substantially, and circular flow is at 70 ~ 75m
3/ h, now reduces gradually to shear circulation pump power, keeps mortar flow 65 ~ 70m
3/ h.When mortar discharges, still keep shearing circulation pump work, turn to discharge tube 9 to discharge electric change valve 7.
After adopting this device, filling in mine quality be improved significantly, realize the continuous feed of sand storehouse, more than continuous pulp discharge 10d, and ensure pulp consistency 63% ~ 66%, emission flow 65 ~ 70m
3/ h.
