Description
Technical field
The present invention relates to the stirring rake in the manganese metal electrolytic solution leaching groove.
Background technology
In the enterprise that produces electrolytic metal Mn (abbreviation electrolytic manganese) with electrolysis process, adopting manganese carbonate ore (rhodochrosite) mostly is raw material, they is prepared into be contained in behind the ore pulp in the leaching groove with leaching electrolytic solution, carries out electrolysis then.For guaranteeing leaching fully, in the leaching groove, be provided with the stirring rake that stirs ore pulp.Concrete structure is, in the leaching groove, be provided with one with the co-axial stir shaft of this leaching groove by its rotation of driven by motor, several layers is set on stir shaft all is immersed in stirring rake in the ore pulp (number of plies of stirring rake leach groove the depth definite) according to reality.When leaching metal manganese electrolyte, actuating motor drives the stir shaft rotation, and then drives the stirring rake rotation and be implemented in whipped state leaching metal manganese electrolyte.Compare with the leaching that stirring rake of no use stirs, its leaching rate increases certainly, still, because stirring rake all is fixed on the stir shaft, and its stir shaft is outside rotate at the center divided by the axis of leaching groove, does not also have the motion of other additional (for example swings and so on).So, ore pulp just has the relative immobilized zone (practise and claim " dead band ") that much is not stirred in the leaching groove, in these " dead bands ", the leaching rate of manganese metal electrolytic solution still can not improve, and then has influence on the leaching rate of manganese metal electrolytic solution in the whole leaching groove.The measure that people take at present is, or the blade length of the number of plies of increase stirring rake or prolongation stirring rake (allowing it as far as possible near the inner side-wall that leaches groove), or greatly improves rotating speed of motor, perhaps haves both at the same time.The result who does like this though can improve some leaching rates, all wants the consumption of energization (electric power).
Summary of the invention
The objective of the invention is, a kind of stirring rake that can save the raising manganese metal electrolytic solution leaching rate of the energy is provided.
The scheme that realizes described purpose is a kind of like this stirring rake that improves manganese metal electrolytic solution leaching rate, aspect same as the prior art is, this stirring rake has several layers, and they all are fixedly mounted on the co-axial stir shaft of leaching groove with manganese metal electrolytic solution, and this stir shaft is by driven by motor; Each layer stirring rake all is immersed in the leaching groove and waits to leach in the ore pulp of metal manganese electrolyte.Its improvements are in the outer end of every layer of each agitating vane of stirring rake, all fixedly to be hung with flexible band; Be positioned at the flexible strip length of upper strata stirring rake, can not swipe in plumbness following time and also scraping degree of being can not take place when being subjected to centrifugal action to launch in described ore pulp rotation with the sidewall of described leaching groove with lower floor's stirring rake; Be positioned at the flexible strip length of orlop stirring rake, can not swipe in plumbness following time and also scraping degree of being can not take place when being subjected to centrifugal action to launch in described ore pulp rotation with the sidewall of described leaching groove with the corresponding part of described leaching trench bottom.
As can be seen, the present invention does not adopt the way that increases the stirring rake number of plies and prolong the blade length of stirring rake, but has fixedly hung flexible band at the blade front end of stirring rake from scheme.Because these flexible bands are along with rotations of stir shaft and stirring rake thereof, can be under action of centrifugal force and upwards pendulum get up, so can reduce " dead band " as blade stirs ore pulp; Again because the flexibility of flexible band itself, and make them after pendulum gets up, also be attended by the shake that does not stop simultaneously, and this shake has destroyed the environment that is similar to " laminar flow " that causes " dead band " further, therefore, mixing effect of the present invention is better, and the leaching rate of manganese metal electrolytic solution just is improved naturally.Obviously, because flexible band stirs under the dither state not stopping, so, as long as its rotating speed can produce enough centrifugal force, just there is no need as prior art, to go to have increased motor speed greatly.Therefore, the present invention can not increase the leaching rate that improves manganese metal electrolytic solution under the energy consumption situation substantially.Checking shows that under identical leaching rate situation, the present invention reduces energy consumption and reaches as high as 12.5%; Under the same consumption energy situation, the present invention can bring up to average 90.8% to average 87.5% of prior art.
Certainly, the advantage that the device among the present invention is simple in structure in addition, equipment cost is low.
The present invention is further illustrated below in conjunction with accompanying drawing.
