Double-horizontal-shaft crossed recurrence continuous vibratory stirring device

Abstract

The invention relates to a double-horizontal-shaft stirring device, in particular to a double-horizontal-shaft crossed recurrence continuous vibratory stirring device capable of promoting material circular crossed recurrence, prolonging the stirring time and improving the stirring quality. The vibratory stirring device comprises two stirring shafts, the two stirring shafts are each connected with a vibration shaft and a vibration exciter, two stirring shafts synchronously and reversely rotate, stirring blades on the two stirring shafts are continuously distributed in a reversely-spiral manner, the stirring blades on each stirring shaft are evenly divided into three sets, three difference mounting included angles exist between the three sets of stirring blades and the axis of the corresponding stirring shaft, a phase angle and an axial gap are mounted between every two adjacent stirring blades, or the stirring blades on the two stirring shafts are in a spiral strip shape; and the spiral angles are decreased progressively, materials circularly propelled in a crossing manner between the two shafts, the material flow motion in a stirring cylinder is more reasonable and stable, it is ensured that the materials are continuously, evenly and forcefully propelled in a stirring cylinder, the stirring time is prolonged, and the stirring quality and the stirring efficiency are improved.

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...

AI Technical Summary

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
