Description
Technical field
The present invention relates to a kind of agitating device, particularly a kind of stirring device for leaching of manganese ore.
Background technology
Produce with electrolytic method in the enterprise of electrolytic manganese metal (abbreviation electrolytic manganese), mostly adopting manganese carbonate ore (manganese spar) is raw material, they is prepared into be contained in after ore pulp and stirs in chemical combination bucket with leaching electrolyte, then carries out electrolysis.In prior art, stirring device for leaching of manganese ore is made up of upright cylindric cell body and the agitator arm that is arranged on its center, and this stirring device for leaching of manganese ore has following shortcoming:
1, in the time that wheel speed is higher, the fluid in groove can be poured into cell wall because of centrifugal force, and liquid level rises near cell wall, and cell body center liquid level declines, and forms whirlpool, or is referred to as " swirling ";
2, along with the increase of wheel speed, whirlpool center is sunk darker, thereby greatly reduces the extraction rate of electrolyte.
For this reason, start in the art to adopt agitating device with baffle plate, comprise cell body and be arranged on shaft and the impeller of its centre junction position; On the inwall of cell body, longitudinally vertical and spacing has equally been installed baffle plate; Baffle plate is isometric, and bottom land is all directed reach in lower end.After improvement, the agitating device with baffle plate can weaken " swirling " of groove inner fluid, has increased the less turbulence of fluid, has improved mixing effect, and the extraction rate of electrolyte is increased, but but has following shortcoming:
1, owing to there will be the partial circulating of electrolyte flow at the back side of baffle plate, and these baffle plates are all rigidity, the hardness of rigid baffle is too large, the resistance of convection cell is very large, thereby make fully mass transfer and the reaction of ore pulp in this partial circulating, therefore form endless loop (being dead angle), caused the insufficient of ore pulp local mixing;
2, insufficient due to ore pulp local mixing, and then have influence on the extraction rate of manganese metal electrolyte in whole agitating device;
3, rigid baffle agitating device increases energy consumption.
Summary of the invention
In order to overcome, cell body central liquid face decline in prior art stirring device for leaching of manganese ore easily forms whirlpool, whirlpool center is sunk more deeply, reduced the extraction rate of electrolyte with the increase of wheel speed, and avoids improving the problem that ore pulp local mixing extraction rate insufficient, manganese metal electrolyte is influenced and rigid baffle agitating device energy consumption is too high that rear technology causes.The present invention proposes a kind of stirring device for leaching of manganese ore, comprises cell body, shaft, and impeller and baffle plate, the vertical longitudinal also spacing of described baffle plate is equally arranged on the inwall of cell body, and described baffle plate is flexible material.
Further, in order to improve the life-span of baffle plate, described flexible material is corrosion resistance soft material.
Further, described corrosion resistance soft material is flexible plastic, soft rubber or macromolecular material.
Further, described corrosion resistance soft material the best is soft pvc plastic.
Further, described baffle plate is 4.
Further, described height of baffle plate/cell body height=0.800～1.200.
Further, described barrier width/cell body internal diameter=0.083～0.100.
The useful technique effect of a kind of stirring device for leaching of manganese ore of the present invention is:
1, under identical operating mode, owing to having adopted at the vertical flexible baffle of longitudinally also installing to spacing phase of agitating device inwall, compared with rigid baffle agitating device, the present invention can constantly be taken away the electrolyte flow in partial circulating after baffle plate by the liquid stream of other direction, new fluid can constantly supplement into, makes the circulation dead band that electrolyte flow forms after groove Internal baffle reduce even to eliminate as far as possible;
2, due to the dead band that makes to circulate reduce electrolyte flow local mixing is very significantly improved, thereby make the mixed effect of full groove electrolyte more desirable;
3, in improving manganese metal electrolyte extraction rate, reduce energy consumption;
4, simple in structure, easily manufactured, equipment cost is low.
