Composite rotary stirring device and working method

Abstract

The invention relates to a compound rotary stirring device and a working method, comprising a tank body, a drive mechanism is provided at the center of the top of the tank body, an output shaft of the drive mechanism is fixedly connected to one end of a swing rod, and the other end of the swing rod A stirring shaft is rotatably connected, and the axis of the stirring shaft deviates from the axis of the tank body. A gear is fixed at the top of the stirring shaft, and the gear meshes with the first internal ring gear arranged on the inner surface of the top of the tank body. The shaft is equipped with a blade mechanism, and the stirring device of the present invention has good stirring effect and good stability in the 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
