The arrangement of the frustum 51 ensures that no suction dead zone exists when the second stirring wheel 22 pushes the materials from bottom to top, so that the materials in the stirring cavity 11 are all stirred.
The bottom of the casing 1 is provided with an inclined bottom 32 inclined toward the discharge opening 31. The sloping bottom 32 allows for more complete discharge.
And the surfaces of the first stirring wheel 21 and the second stirring wheel 22 are sprayed with wear-resistant polymer coatings. The high-molecular coating improves the wear resistance and prevents the slurry from being adhered to the surface of the stirring wheel to be condensed to influence the use.
The main use of this device is, the material is put into stirring chamber 11 by apron 12, add the back that finishes, set up two stirring wheels into the syntropy rotatory earlier, let because the upper and lower layering that the density difference leads to mixes on a large scale in advance, two stirring wheels are all down the propelling movement material, cause the flow in the full height within range of stirring chamber 11, the layering about eliminating, the preliminary unified back of density, the steering of adjustment second stirring wheel 22, it is opposite with first stirring wheel 21 to make it, the propelling movement direction of two stirring wheels one on the other, the material not only produces the axial offset and mixes, still can produce the circumference shearing because the difference of direction of rotation, it is more thoroughly even to mix, the material after the completion of mixing is outside discharge gate eduction gear.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
