traditional powder mixes mainly adopts level and smooth inner wall compounding jar, and it can lay on compounding mechanism, and rotation or upset through compounding mechanism make the powder production in the jar flow, rely on relative motion between the powder in order to reach the purpose with powder material homogeneous mixing. Because the inner wall of the used charging bucket is smooth, the friction force of the inner wall of the container to the powder is small in the powder mixing process, the relative motion between the inner wall and the powder is greatly reduced, the effect of uniform mixing can be achieved only by means of long-time rotation of the mixing mechanism, and the mixing efficiency is low and the effect is poor. And the mixing efficiency is greatly influenced by the volume of the powder materials, the volume of the mixing container is fixed, the larger the volume of the powder materials is, the smaller the space for the powder to move is, and the relative movement between the powder is reduced, so that the mixing efficiency is reduced.

Detailed Description

The following description sufficiently illustrates specific embodiments of the invention to enable those skilled in the art to practice and reproduce it.

High-efficient mixing vessel of powder includes: a material receiving port 1, a container 2 and a bulge 3. The material receiving port 1 is arranged at the top of the container 2, and the protrusion 3 is arranged on the inner wall of the container 2.

The material receiving port 1 is provided with a sealing valve 11, and the sealing valve is a sealing valve which can be disassembled or not; a sealing gasket is arranged between the detachable sealing valve and the material receiving port 1, and the outside of a joint of the sealing valve and the material receiving port 1 is clamped by a clamp; the non-detachable receiving opening can be directly welded on the receiving opening 1.

The shape of the protrusions 3 is a dot-shaped protrusion 31, a linear protrusion 32 or a planar protrusion 33, and the mixed arrangement of the dot-shaped protrusion 31, the linear protrusion 32 or the planar protrusion 33 may be provided on the inner wall of the container 2.

The container 2 may also be provided with one or more replacement nozzles 21. The sealing valve 11 is used to seal the material and gas in the container 2 and prevent the material and gas from escaping or escaping.

As shown in FIG. 1, the linear protrusions 32 of the present invention are shown as a spiral line.

The shape of the linear protrusion 32 may take one or more of a straight line, a curved line, or a spiral line.
