Double-shaft stirrer

Abstract

A double-shaft stirrer comprises a shell, a first stirring shaft and a second stirring shaft, wherein a stirred tank is arranged in the shell, the first stirring shaft and the second stirring shaft are respectively arranged in the stirred tank in parallel along the first axis and the second axis; the two ends of the first stirring shaft and the second stirring shaft are supported at the two sides of the shell by bearings; the first stirring shaft and the second stirring shaft can rotate relative to the shell; at least a first blade and at least a second blade which are opposite in directions are arranged on the first stirring shaft and the second stirring shaft; and the double-shaft stirrer is simple in structure and convenient in operation and can mix plenty of stirring materials, thereby realizing the uniform mixing.

Description

technical field [0001] The invention relates to the field of stirring machinery, in particular to a double-shaft stirrer for mixing materials. Background technique [0002] In the existing material mixing, two rotatable parallel shafts can be arranged in the stirring tank, and stirring blades are set on the shafts. During the rotation of the shafts, the materials are stirred by the rotation of the stirring blades. The materials in the stirring tank are circularly rotated and mixed repeatedly in the horizontal plane of the stirring tank. The usual stirring blades are helical, so that the materials move forward gradually along the axis and mix with each other at the same time. [0003] But, although this conventional stirrer can improve the axial moving speed of material, because the stirring blades on both sides are helical, therefore, the moving of the stirred material from one shaft to another shaft is not very smooth. Smooth, thus, the stirring materials of the two shafts...

Problems solved by technology

[0003] But, although this commonly used stirrer can improve the axial moving speed of material, because the stirring blades on both sides are helical, therefore, the moving of the stirred material from one shaft to another shaft is not very smooth. Smooth, thus, the stirring materials of the two shafts are difficult to mix with each other, the density of the material collision is not enough, it is difficult to form the mixing cycle movement of the materials between the two shafts

[0004] As a result, the heavy material of the agitator cannot be circulated uniformly, which will easily lead to uneven biaxial mixing, and it is difficult to achieve uniform high-quality material mixing
