Small-size high-speed dispersion machine for laboratory

Abstract

The invention discloses a small-size high-speed dispersion machine for a laboratory. The small-size high-speed dispersion machine comprises a base and a support rod, wherein the support rod is fixed on the base; a lifting frame capable of moving up and down is arranged on the support rod; a stirrer is fixedly connected with the end part of the lifting frame; the dispersion machine further comprises a fixer for fixing a material drum; the fixer is connected with the support rod; a material drum mounting position corresponding to the stirrer is formed on the end part of the fixer. The small-sizehigh-speed dispersion machine has high safety, is capable of effectively preventing accident from happening and is suitable for dispersion and mixing of the materials in the liquid. The small-size high-speed dispersion machine has the advantages of simple structure, high dispersion efficiency, excellent mixing effect, low manufacturing cost and convenience in popularization.

Description

technical field [0001] The invention relates to the technical field of laboratory stirring devices, in particular to a small-scale high-speed disperser for laboratories. Background technique [0002] In research laboratories involving paints, coatings, inks, adhesives, dyes, etc., it is often necessary to stir, mix, dissolve, homogenize, or disperse materials. The best equipment for achieving the above operations in industry is high-speed Disperser. The so-called high-speed disperser is a kind of mixer. During the stirring process, the material is continuously ejected from the radial direction at high speed, and the flow direction is changed under the resistance of the material itself and the container wall. At the same time, the upper and lower shafts are generated in the rotor area. Under the action of the suction force, the upper and lower two strong reactionary turbulent flows are formed, and the material goes through several cycles, and finally completes the process of...

Problems solved by technology

[0003] The invention patent with the application number 201220030866.3 discloses a laboratory disperser, which includes a base, a motor and a stirring rod. The base is fixed with a support rod, the support rod is covered with a sleeve, and the sleeve is provided with a locking valve. The upper end of the stirring rod is fixedly connected to the output shaft of the motor, and the motor is installed on the sleeve. This invention is suitable for use in the laboratory, but in the process of dispersion, the vortex caused by the stirring will easily make the material cylinder Shake or even fall; the sleeve is set on the support rod, and the sleeve covers the support rod. When the sleeve moves up, it is easy to separate from the support rod, making the motor easy to fall, and the safety is not good. Therefore it is necessary to improve it
