Abstract
The invention relates to an overlapped turbine type bead separator of a medium stirring mill. The overlapped turbine type bead separator comprises a static ring, an overlapped turbine set and an outer turbine, wherein the static ring is inlaid in the side of a discharging chamber wall, close to a grinding chamber; each turbine blade is provided with a plurality of vortex chutes, a plurality of inclined holes and an annular diversion trench, which are all communicated with one another. One side of the overlapped turbine set clings to the outer turbine, and the other side of the overlapped turbine set is separated from the static ring to form a proper annular discharging clearance; and when a rotor and the turbine set are driven by a main shaft to rotate, the vortex chutes among laminations generate a centripetal absorption force for driving slurry to enter the annular diversion trench, and the inclined holes arranged in the annular diversion trench are used for driving the slurry to be discharged from a discharging hole along the axial direction. Beads are radially thrown away and do radial circulated motion under the action of a centrifugal force generated when the outer turbine rotates, so that the beads are prevented from being accumulated around the bead separator, and the discharge of materials can not be blocked. The overlapped turbine type bead separator is low in manufacturing cost; by using the overlapped turbine type bead separator, the grinding efficiency is greatly increased and the granularity of particles in primarily-ground slurry is remarkably reduced; and compared with the traditional product of the same type, the overlapped turbine type bead separator can be used for increasing the yield by 50-130%.

Described outer turbine, its vortex groove and lamination vortex groove opposite direction produce centrifugal eddy current during main shaft drives, the mill pearl in the turbine is dished out, and order about the mill pearl and make circular motion and shuttling movement radially, prevent from grinding pearl and accumulate in and block slurry around the turbine lamination and discharge.
The present invention compared with prior art has and is following advantage and beneficial effect:
1) because the lamination eddy current produces powerful centripetal suction, under the suction of lamination vortex groove, slurry can be inhaled into easily in the lamination guiding gutter and flow to inclined hole, inclined hole on the lamination produces powerful axial motive force the slurry in the guiding gutter is pushed to discharging opening, under the pressure-acting of external charging pump, add the driving force that closed assembly turbine group self produces, slurry is smoothly discharged, flow increases considerably, and production efficiency can increase substantially.
2) because the lamination turbine is the Dynamic Separation structure that self produces driving force, have the self-cleaning function, material is non-caked, nothing is stopped up, and discharge is more unobstructed.
3) because the effect of outer turbine, circular motion and the radial circulation motion of mill pearl have been strengthened, strengthened the grinding effect, throwing that the more important thing is turbine effect of getting rid of prevent from grinding pearl gather be squeezed in lamination around block material discharge, thereby so that flow be further enhanced.Simultaneously, be squeezed in separator surface generation grinding owing to having prevented that the mill pearl from gathering, reduced the wearing and tearing to separator, improved the life-span of separator.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
