Composite rotary stirring device and working method thereof

Abstract

The invention relates to a composite rotary stirring device and a working method thereof. The composite rotary stirring device comprises a tank body, wherein a driving mechanism is arranged in the center of the top of the tank body; an output shaft of the driving mechanism is fixedly connected with one end of an oscillating bar; the other end of the oscillating bar is rotatably connected with a stirring shaft; the axis of the stirring shaft is deviated from the axis of the tank body; a gear is fixed on the top of the stirring shaft and is engaged with a first inner gear ring arranged on the inner side surface of the top of the tank body; and the stirring shaft is provided with a blade mechanism. The stirring device is good in stirring effect and is good in stability in a working process.

Description

technical field [0001] The invention relates to the technical field of stirring equipment, in particular to a composite rotary stirring device and a working method. Background technique [0002] Stirring device is one of the most common mixing devices in the industry, and is widely used in chemical, food, biological, pharmaceutical and other industrial production. The stirred reactor mainly relies on the stirring paddle to mix the materials to form the flow pattern required by industrial production, and mix the same materials or different materials. [0003] The existing stirring device includes a tank body, the inner center of the tank body is provided with a stirring shaft, the stirring shaft is provided with blades, the stirring shaft is connected with a driving mechanism, the driving mechanism drives the rotation of the stirring shaft, and the material inside the tank body is processed. Stir. [0004] The inventors found that because the stirring shaft of the existing ...

Problems solved by technology

[0004] The inventors found that because the stirring shaft of the existing stirring device is arranged at the center of the tank body, the internal flow field is symmetrical and the stirring effect is not good. At present, an eccentric stirring device has appeared, and the stirring shaft is arranged eccentrically with respect to the axis of the tank body, which can Breaking the symmetry of the flow field makes the pressure of each point of the flow field different and improves the stirring effect. However, the inventors found that the existing eccentric stirring device is unstable and prone to periodic vibration, which is suitable for smaller tanks If it is applied to a larger tank, corresponding vibration reduction measures need to be taken, and the equipment cost is high. In addition, due to the eccentric setting of the stirring shaft, the stirring effect on the eccentric side will be good while the stirring effect on the other side will be good. Bad phenomenon
