Description

Technical Field

[0001] The invention relates to a stirring blade and belongs to the technical field of vertical-shaft planetary mixers. Background Art

[0002] Vertical planetary mixer is a kind of engineering machinery, which is mainly used for stirring and mixing various powder, granular and slurry materials.

[0003] The mixing blade is one of the key parts in the mixer. Its shape and installation angle have a great influence on the mixing effect and mixing efficiency. The mixing blades of the existing vertical axis planetary concrete mixer are generally trapezoidal and parallelogram flat plate structures. The blade facing the material is flat and there is only one blade. When mixing various materials with high viscosity and poor fluidity, the flow resistance of the material in front of the blade body is relatively large, which is not conducive to the turning over and diversion of the material, which will affect the mixing effect and increase unnecessary energy consumption, causing unnecessary wear and deformation of the mixing device. Summary of the invention

[0004] In order to overcome the defects of the prior art, the present invention provides a stirring blade to solve the problem that the conventional general stirring blade mentioned in the background art has a large flow resistance in front of the blade body when stirring various materials with high viscosity and poor fluidity, which is not conducive to the turning up and diversion of the materials. The technical solution of the present invention is:

[0005] A stirring blade comprises a blade body, wherein the blade body is arranged in an arc shape as a whole, the front of the blade body forms a material-facing surface, and the rear is a material-receiving surface, and the material-receiving surface of the blade body forms a vertical surface, an inclined back surface and a back arc surface in sequence from top to bottom, and a mounting surface is arranged on the outer side of the inclined back surface, and the mounting surface is higher than the vertical surface, and a first angle is formed between the inclined back surface and the vertical surface, and the material-facing surface comprises a main material-facing surface and a side material-facing surface arranged in sequence, and a convex ridge is arranged between the main material-facing surface and the side material-facing surface, and the main material-facing surface and the side material-facing surface form a second angle with the horizontal plane.

[0006] A connecting mechanism is arranged in the middle of the blade body, and the connecting mechanism includes a countersunk hole and a through hole arranged coaxially with the countersunk hole. The through hole is arranged on the back of the countersunk hole. The countersunk hole is communicated with the through hole and is arranged in a stepped shape as a whole. The rear part of the through hole extends to the back material surface, and the front part of the countersunk hole extends to the front material surface.

[0007] The axes of the countersunk hole and the through hole are perpendicular to the mounting surface.

[0008] The first angle is A, wherein 20≤A≤45°.

[0009] The second angle is an acute angle.

[0010] One side of the main material-facing surface forms a third angle with the horizontal direction, and the other side forms a fourth angle with the horizontal direction. The third angle is B, where 30°≤B≤65°; the fourth angle is C, where 110°≤B≤150°

[0011] The main material-facing surface is a streamline structure that is flat in front and steep in the back. The lower part of the main material-facing surface (3) forms a fifth angle with the horizontal plane, and the fifth angle is D, wherein 20°≤D≤45°. The middle part of the main material-facing surface is a curved surface, wherein the upper part of the main material-facing surface (3) forms a sixth angle with the vertical plane (2), and the sixth angle is E, wherein 10°≤E≤35°.

[0012] The arc-shaped back surface and the horizontal plane form a seventh angle, which is E, wherein 5°≤F≤30°.

[0013] The blade body is integrally formed by mold casting.

[0014] The blade body is made of cast iron or cast steel.

[0015] The advantages of the present invention are: the blade body of the present invention has a streamlined structure, with a main and side material-contacting surfaces. The main material-contacting surface is a streamlined structure that is flat in front and steep in the back. The material has better fluidity on the surface of the blade body and is more conducive to scooping and turning over the material. The combined effect of the main material-contacting surface and the side material-contacting surface is more conducive to guiding the material to turn over and flow to both sides in front of the blade body, which is also conducive to reducing the problems of sticking and wear of the stirring arm. The ridges between the main material-contacting surface and the side material-contacting surface are helpful in cutting the clumped material. In addition, the blade body is easy to install and adjust, simplifying the structure of the stirring arm. BRIEF DESCRIPTION OF THE DRAWINGS
