Abstract

The utility model discloses a stirring barrel with flow guiding ring seat which is composed of a barrel body, a main shaft, an impeller, a vertical flow guiding baffling board, an annular flow guiding ring arranged at the bottom of the barrel, and a taper flow guiding seat. The utility model can eliminate the dead space of the coarse grained materials depositing at the bottom of the barrel. The utility model has the advantages of simple structure, high efficiency, and low maintenance cost.

Description

Stirring barrel with flow guiding ring seat

The invention belongs to solid-liquid diphase system agitator, particularly be applicable to the even stirring of industry high concentration solid-liquid diphase system materials such as mine or chemical industry.

At present, known both at home and abroad solid-liquid diphase system agitator is of a great variety, such as publish Chemical Industry Press in December, 1985 " 22 pages of the 5th piece of Chemical Engineering handbook " stir and mix " and 70 pages summary, for improving mixing effect, along the agitator inwall some vertical flow aprons are installed, in order to the elimination phenomenon that swirls; Branch flat for having at the bottom of the bucket, Saucer Bottom, some agitator is installed small front apron at the bottom of bucket, though rotatablely moving of fluid produces a little ascending motions near at the bottom of making barrel, but still there is the dead angle, make the solid matter deposition, forming the dead band near middle part, the periphery at the bottom of the bucket, non-uniform phenomenon occurs stirring.

Task of the present invention provides the high density slurry agitator that annular guide ring, diversion seat are set at the bottom of a kind of barrel, make rotatablely moving of barrel underflow body become ascending motion, slurry is under the effect of diversion seat annular guide ring and vertical flow apron, form axial flow, make a barrel substrate material translate into the slurry surface, eliminated the dead band of coarse material at the bucket bottom sediments.The present invention is simple in structure, and energy consumes little, and maintenance cost is low, is best suited for solid proportion less than 4.85, and maximum particle diameter is less than 2 millimeters, and average grain diameter is less than 0.36 millimeter, and weight concentration evenly stirs less than 70% high underflow.

Describe structure of the present invention in detail below in conjunction with accompanying drawing.

Front section view of the present invention shown in Figure 1.

Fig. 1 shown in Figure 2 is along the A-A cutaway view.

High as shown in Figure 1 and Figure 2 underflow agitator comprises stirring cylinder 1, and an agitator is set in staving, and these agitator main shaft 2 lower ends connect firmly the impeller 3 of straight plate tilting blade, and the upper end of main shaft links by decelerator and motor; At the inwall of staving at least four the vertical deflectors 4 that are uniformly distributed along the circumference; Along circumference an annular guide ring 5 is set at staving; Middle part at the bottom of bucket is provided with a taper diversion seat 6; The radius of curvature optimum value of the curved surface of this taper diversion seat equals the radius of gyration of impeller.Staving inwall along the bucket bottom is provided with an annular guide ring 5, and the curvature of curved surface radius optimum value of this guide ring is 1/4th agitator diameters.The rotation of agitator paddle 3 makes its slurry under the synergy of taper diversion seat, annular guide ring and vertical flow apron, produces flowing from bottom to top along the agitator outside, and the slurry in the agitator centre produces top-down flowing.Thus, slurry forms the systemic circulation of sealing vertically and flows in agitator, make slurry granularity and CONCENTRATION DISTRIBUTION even.

Claims (3)

1, a kind of agitator that has the water conservancy diversion ring seat is made up of staving, main shaft, impeller and vertical flow apron, it is characterized in that along circumference annular guide ring being set at the bottom of bucket, and the middle part is provided with the taper diversion seat at the bottom of bucket.

2, according to the described agitator of claim 1, the surface that it is characterized in that guide ring, taper diversion seat is a curved surface.

3, according to claim 1 or 2 described agitators, it is characterized in that: the optimal curvatures radius of taper diversion seat curved surface equals the radius of gyration of agitator arm, and the curvature of curved surface radius optimum value of annular guide ring is 1/4th agitator diameters.
