Continuous vibrating stirring device with double horizontal axis cross recursion

Abstract

The invention relates to a twin-shaft stirring device, in particular to a continuous vibrating stirring device with twin-shaft cross-recursion that promotes material circulation and cross-propelling, prolongs the stirring time, and improves the stirring quality. The vibration shaft and the vibrator are respectively connected, and the two stirring shafts rotate in reverse synchronously. The stirring blades on the two stirring shafts are continuously distributed in a reverse spiral shape. The stirring blades on each stirring shaft are divided into three groups. There are three different installation angles between the stirring blade and the axis of the stirring shaft, and there are installation phase angles and axial gaps between adjacent stirring blades, or the stirring blades on the two stirring shafts are all ribbon-shaped, and the helix angle Decrease, the material circulates and advances between the two shafts, making the material flow movement in the mixing tank more reasonable and stable, ensuring continuous, uniform and powerful advancement of the material in the mixing tank, prolonging the mixing time, and improving the mixing quality and mixing efficiency.

Description

technical field [0001] The invention relates to a twin-horizontal-shaft stirring device, in particular to a continuous vibrating stirring device with double-horizontal shafts crossing and recursively advancing material circulation, prolonging the stirring time and improving the stirring quality. Background technique [0002] The twin-shaft continuous mixer is a continuous forced mixer. Compared with the batch mixer, it has the advantages of simple structure and high production efficiency, but because of its short mixing time, it has relatively high requirements for mixing quality. Mature, so it has become one of the development directions of mixing equipment. As the core part of the stirring equipment, the stirring device directly affects the stirring quality and stirring efficiency of the whole machine. When the mixer is working, the stirring shaft drives the stirring blade installed on it to rotate, forcing the material to move according to the predetermined track. The m...

Problems solved by technology

For these large-capacity twin-shaft continuous mixers, the capacity of the mixing drum increases and the length of the stirring shaft increases. If the installation method of opposed blades is adopted, the number of mixing blades installed on the stirring shaft will increase accordingly, resulting in the above-mentioned "material blocking" "Phenomenon and the lack of rigidity of the stirring shaft are more serious, which is extremely unfavorable to the stirring effect

[0005] As a conventional forced mixer, the twin-shaft continuous mixer has long had the problem that it is difficult to mix the mixture uniformly on the microscopic level, and when the stirring device is working, there is an inherent "linear velocity gradient" along the radial direction of the stirring shaft. ", resulting in low-efficiency stirring area near the stirring shaft, which delays the working time of the whole machine and affects the mixing quality; on the other hand, the fluidity of the mixture in the low-efficiency area is poor, and it is easy to adhere to the stirring shaft, resulting in "shaft holding Phenomenon, not easy to clean
