Abstract
The invention provides a manganese ore pulp stirring paddle with long service life. The manganese ore pulp stirring paddle provided by the invention comprises a stirring shaft and a stirring paddle connected to the stirring shaft and immersed in manganese ore pulp. In the invention, the outer surfaces of the stirring shaft and the stirring paddle are respectively provided with an isolation layer covered by chloroprene rubber or natural rubber. In the invention, the stirring shaft and the stirring paddle are isolated from manganese ore powders by means of covering the chloroprene rubber or natural rubber, so that the stirring shaft and the stirring paddle are not directly rubbed with the manganese ore powders, equivalently, the diameter of the stirring shaft is increased, and the width and thickness of the stirring paddle are widened and thickened. The densities of the chloroprene rubber and the natural rubber are far less than that of the material of the stirring paddle, so that the weight of the whole stirring paddle is slightly increased, and motors with larger power are not necessary to be replaced. Briefly, in the invention, the service life of the stirring paddle is prolonged by virtue of additionally arranging the isolation layer, so that the production halt loss (caused by replacing the crapped stirring paddle) is reduced. Compared with the prior art, the manganese ore pulp stirring paddle provided by the invention has the advantage that the total production cost is greatly reduced.
Description
Technical field
The present invention relates in manganese metal electrolyte leaching groove, stir the paddle of manganese ore slurry.
Background technology
In producing the electrolytic manganese metal enterprise of (being called for short " electrolytic manganese "), be to be raw material that manganese carbonate ore (manganese spar) manganese ore powder is prepared into ore pulp (i.e. " manganese ore slurry ") earlier mostly, from manganese ore slurry, leach the electrolyte that to contain manganese then, again this electrolyte is carried out electrolysis to obtain electrolytic manganese.The process of leaching electrolyte is finished in the leaching groove, for guaranteeing that leaching fully, promptly improves the extraction rate of manganese metal electrolyte, just is provided with the paddle that stirs manganese ore slurry in the leaching groove.The concrete structure of its paddle comprises, (usually by driven by motor its rotation) shaft coaxial with this leaching groove, and what be provided with on shaft is immersed in stirrer paddle in the manganese ore slurry.After being provided with paddle, the extraction rate of manganese metal electrolyte is improved really.Yet, because contained manganese ore powder has certain degree of hardness after all in the manganese ore slurry, so, be immersed in stirrer paddle and the shaft (made with common iron usually) in the manganese ore slurry, can wearing and tearing appear because of with the manganese ore powder friction taking place all.So, the time shorter only have three months, longer only about half a year, the paddle that more renews because of heavy wear with regard to having to.Both strengthened equipment cost, the stopping production loss that also exists the paddle scrapped because of replacing to cause.
In order to prolong the service life of paddle, reduce the number of times that more renews paddle and the loss that stops production, the someone considered to do paddle with more wear-resisting material.Yet since anti-abrasive material not only itself is more expensive, and also much higher than with common iron of processing cost, the cost of whole paddle has just increased too much.Also there is people Ceng Xiang to cross and still uses common iron, but adopt overstriking shaft diameter, widen, thicken the measure of the width and the thickness of stirrer paddle, come the postponed obsolescence time.But the result who does has like this strengthened the weight of whole paddle, has increased at least again to drive the motor load that paddle rotates; If change powerful motor, its total production cost is still higher.
Summary of the invention
The objective of the invention is, a kind of manganese ore slurry paddle that can save total production cost, long service life is provided.
The scheme that realizes described purpose is a kind of like this manganese ore slurry paddle of long service life, and its aspect same as the prior art is, this paddle comprises a shaft, is connected on this shaft and is immersed in stirrer paddle in the manganese ore slurry.Its improvements are that the outer surface of described shaft and stirrer paddle all has the separation layer that is covered by neoprene or natural rubber.
As can be seen, the present invention comes shaft and stirrer paddle are kept apart with the manganese ore powder by covering the measure of neoprene or natural rubber from scheme, with prevent their directly generation rub; The width and the thickness of stirrer paddle have been widened, thickened to this also the has been equivalent to overstriking diameter of shaft.Because the density (proportion) of neoprene and natural rubber is far smaller than the density of the material of paddle own, therefore, the weight of whole paddle increases seldom, i.e. motor load increase is minimum, need not change more powerful motor.In brief, the present invention is the service life that prolongs paddle by the measure that increases separation layer, minimizing (paddle of scrapping because of replacing causes) stopping production loss.Compared with prior art, total production cost has more reduction.
The present invention is further illustrated below in conjunction with accompanying drawing.
