The invention discloses a magnetic mixing device. The device mainly comprises a drive component, a driving rotor, a material container, a lower mixing paddle, a paddle shaft, a paddle shaft support and an upper mixing paddle, wherein the drive component drives the driving rotor to rotate through a transmission device; and through magnetic attraction, the driving rotor drives the mixing paddles in the material container to synchronously rotate to stir and mix materials. The magnetic mixing device disclosed by the invention realizes the purpose of mixing the materials by driving the mixing paddles to rotate through non-contact magnetic transmission, the mixing paddles are not substantially connected with the drive component, and at most four mixing effects can be combined through different mixing paddle structures and control methods; the device solves the problems that during a material mixing process in industrial application and experiments, gas in an inner cavity of a container leaks, the connection sealing and the cleaning are difficult, and the installation is troublesome; and the device improves the effect of ordinary magnetic mixing, plays the advantages of magnetic mixing, and realizes efficient material mixing under specific conditions.
Description
technical field [0001] The invention relates to a stirring device driven by magnetic force, which belongs to the field of mechanical mixing. Background technique [0002] Stirring device is a device for forced convection and uniform mixing of liquid and gaseous media. The type, size and speed of the stirrer have an effect on the distribution of the stirring power between the bulk flow and the turbulent pulsations. At present, various types of agitators are commonly used in industry and laboratories. Selecting a suitable agitator according to parameters such as the viscosity of the material can achieve better processing or experimental results. However, the stirring device commonly used in the current application is that the driving device drives the rotating shaft to rotate through the mechanical transmission method, and the stirring blade on the rotating shaft realizes the stirring of the material. The stirring blades are connected by mechanical transmission, so it has a ...
