Stirring device

Abstract

The invention discloses a stirring device which comprises a stirring cylinder, an inner stirring shaft, an outer stirring shaft, a rotation driving mechanism and a linear driving mechanism, wherein stirring blades are arranged at the lower end of the outer stirring shaft; the outer stirring shaft is connected with the linear driving mechanism; the linear driving mechanism drives the outer stirringshaft to move up and down; a circumferential fixing mechanism is arranged between the outer stirring shaft and the inner stirring shaft; the rotation driving mechanism drives the inner stirring shaftto rotate; and at the same time, the inner stirring shaft drives the stirring blades of the outer stirring shaft to rotate and agitate through the circumferential fixing mechanism. The stirring blades of the device can move up and down during rotation; an agitation amplitude is large; the inner circulating of materials is facilitated; material layering under a laminar condition is avoided; the device is large in heat exchange area and high in heat exchange efficiency; the stirring cylinder is internally provided with a heating device and temperature induction devices, so that a temperature during material stirring can be controlled; a controller controls a heating temperature of the heating device, a rotating rate of the rotation driving mechanism and a moving rate of the linear driving mechanism; and therefore, a stirring status of the stirring materials can be controlled precisely.

Description

technical field [0001] The invention belongs to the technical field of mixers, and more specifically, the invention relates to a mixer. Background technique [0002] A stirring device is a device in which a shaft with blades rotates in a cylinder or a tank to stir and mix various raw materials to form a mixture or a suitable consistency. The material realizes physical and chemical reactions such as dispersion, mixing and dissolution in the stirring device. On the one hand, in the application of stirring process, especially the reaction of high-viscosity materials, in the process of crystallization and heat exchange, the size of the heat exchange area and the heat exchange efficiency of the stirring device are very important to the influence of the entire stirring process. On the other hand, in the process of stirring materials, for materials with poor compatibility or limited mixing ability, if the suction force of the stirring is not controlled properly, stratification wil...
