Description
Technical field
The utility model belongs to mining equiment flotation technology field, is specifically related to a kind of flowsheet of slurry agitation bucket, can play the effect that strengthening sizes mixing promotes that mineral floating reclaims.
Background technology
At mining processing industry especially in industrial flotation, essential ground will use flowsheet of slurry agitation device, in the bucket holding ore pulp, agitating device is set, main purpose is that the slurry in ore pulp is mixed, existing flowsheet of slurry agitation bucket that is that delivered and commercial Application, what often more focus on is axial stream effect in strengthening agitator.As Chinese utility model patent CN200820124070 adopts working surface to be the multi-layer impeller of helicoid, the blade rotation direction of adjacent fan-wheel is identical or contrary, and main purpose is the axial convective motion of strengthening, thus strengthening whipping process.But actually, before ore dressing especially flotation, selective aggregation/dispersity good between mineral grain, to improving the selective extremely important of separation, only emphasizes that the agitating mode of axial stream effect often can not obtain good flotation effect.
Utility model content
The agitating mode of existing flowsheet of slurry agitation bucket mainly emphasizes axial stream effect, its objective is and makes ore particle suspend and mix with medicament.The technical problem that the utility model solves is: provide a kind of flowsheet of slurry agitation bucket having multidirectional stream and stir, the multiple action of axial stream, radial flow and slipstream taken into account by inner agitating device, is conducive to selective aggregation/dispersion and mixing between mineral grain.
The utility model adopts following technical scheme to realize: a kind of flowsheet of slurry agitation bucket, the agitating device comprising staving 3 and be arranged in staving, described agitating device is the coaxial upper and lower two-layer impeller arranged, and the radius of gyration of described upper strata impeller 6 is less than the radius of gyration of lower floor's impeller 7.
Preferably, the radius of gyration of described upper strata impeller 6 is 0.75-1 times of the radius of gyration of lower floor's impeller 7.
Further, described upper strata impeller 6 is flat leaf oar, and its blade surface is the plane tilted.
Preferably, the blade of described upper strata impeller 6 meets the angular range between slurry face and horizontal plane is 95 °-135 °.
Further, the height and position of described upper strata impeller 6 is lower than overfall at least more than the 300mm of agitator staving.
In the utility model, described upper strata impeller 6 and lower floor's impeller 7 are fixed on same shaft 4 respectively by impeller set 61, and described shaft 4 is connected with transmission device 1.
In the utility model, described staving 3 inwall is provided with ultrasonic unit 5.
The difference of the utility model and prior art is: the blade of upper strata impeller is flat leaf oar, and its working surface is the plane tilted, not existing helical blade, and upper strata impeller is in order to strengthen the radial flow effect of the ore pulp in staving; Lower floor's impeller does not require the blade adopting same type with upper strata impeller, lower floor's impeller tactical diameter is greater than upper strata impeller simultaneously, can the effect of simultaneously the axis stream of balanced staving flow field, radial flow and slipstream, assisting in conjunction with inner wall of barrel ultrasonic unit, thoroughly can realize the mixing in ore pulp.
From the above mentioned, the utility model strengthens the effect of radial flow by the oblique oar of the plane of upper strata impeller, the reasonable combination of upper strata impeller and lower floor's impeller constructs the agitator flow field being conducive to selective aggregation between mineral grain/multiple action such as dispersion and mixing, ore pulp after agitator of the present utility model is sized mixing, be easier to sorting, better mineral processing index can be obtained, the blade paddle type of the utility model to agitating device lower floor impeller does not specially require, the blade paddle type of ore pulp mixing can be used for, therefore be easy to apply in flowsheet of slurry agitation.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
