Space sport mixer

Abstract

A space motion mixer comprises a crank arm, a rocking bar, a container frame, a mixing container, a machine frame, a speed reduction gearing, a motor, etc. The mixing container with a helical line-shape scraping blade therein is arranged inside the container frame, two ends of the container frame are mechanically connected to the crank arm via a ball pair and the rocking bar via a universal joint respectively, and the crank arm and the rocking bar are respectively connected with a rotary pair and the machine frame. When the crank arm rotates in a complete alternation, the rocking bar swings around the machine frame, and the mixing container has a space motion containing rotation and movement; because of the space quick return motion and helical curve scraping blade, the materials in the container can generate a three-D projecting motion along axial, radial and circumferential directions for driving materials to be in a conglomeration and diffusion motion alternately for thorough mixing to have a good mixing effect and a high mixing efficiency, additionally, the invention is provided with simple structure, and can be controlled conveniently and manufactured easily.

Description

Technical field [0001] The invention relates to a spatial three-dimensional motion mixer, which is suitable for efficient mixing of two or more materials with different specific gravity, and has a compact structure and is easy to install, repair, clean and maintain. Background technique [0002] At present, there are many kinds of rotating container mixers at home and abroad, including traditional cylindrical mixers, single and double cone mixers, V-shaped mixers, etc. However, when the materials of this type of mixer are turned in the container, they mainly rely on simple rotation. During movement, the material can only be separated-combined and combined-divided in simple diffusion and flow. The mixing efficiency mainly depends on the rotation speed, and the rotation speed should be less than the critical speed, generally 30%-50 of the critical speed. %, the rotation speed is too high. Due to the centrifugal force, materials with different components and different specific gravi...

Problems solved by technology

[0002] At present, there are many kinds of rotating container mixers at home and abroad, including traditional cylindrical mixers, single and double cone mixers, V-shaped mixers, etc., but when the materials of this type of mixer are turned over in the container, they mainly rely on simple rotation. Movement, when working, can only make the material do the simple diffusion and flow of separation-combination and combination-separation. The mixing efficiency mainly depends on the rotation speed, and the rotation speed is less than the critical speed, generally 30% to 50% of the critical speed. %, the rotating speed is too large, due to the generation of centrifugal force, the materials with different components and different specific gravity will produce specific gravity segregation and accumulation phenomenon in the mixing process, so that the mixing of materials will be uneven, resulting in the reduction of mixing efficiency; the rotating speed is too slow, can not produce the required The strong turning action and due shear speed, the mixing efficiency is low
