Large-sized static mixer

Abstract

The invention provides a large-sized static mixer. The large-sized static mixer comprises a pipeline and a mixing unit arranged in the pipeline, wherein openings are formed in two ends of the pipeline; the mixing unit comprises a first blade, a second blade, a third blade and a fourth blade which are of a circular arc sheet shape; the first blade and the second blade are arranged in an opposite crossing manner, the axis of the crossing point is level, the first blade forms a downward deflection angle around the axis of the crossing point, and the second blade forms an upward deflection angle around the axis of the crossing point; the third blade and the fourth blade are arranged in an opposite crossing manner, the axis of the crossing point is vertical, the third blade forms a right deflection angle around the axis of the crossing point, and the fourth blade forms a left deflection angle around the axis of the crossing point; the rear end of the first blade is connected with the plate surface of the third blade, the rear end of the second blade is connected with the plate surface of the fourth blade, the front end of the third blade is connected with the plate surface of the second blade, and the front end of the fourth blade is connected with the plate surface of the first blade. By virtue of a special blade combination manner, the integral structural strength of the mixer is enhanced, and by virtue of a reasonable integral structure, the mixer has excellent mixing efficiency.

Description

technical field [0001] The invention relates to the field of mixers, in particular to a large static mixer. Background technique [0002] In various industries, common process sections, such as mixing, reaction, absorption, extraction, etc., require uniform dispersion and full mixing of different fluids. In order to achieve the purpose of mixing, stirring is usually used. The mixer not only needs to be driven by electric energy, but also takes up a lot of space, and it takes a long time to stir and mix, and the mixing uniformity is limited. [0003] The mixer is to install a mixing unit in the pipeline. When the fluid flows in the pipeline, it will generate disturbance under the action of the mixing unit, so that various fluids can be mixed with each other. The inner core structure of a mixer determines the mixing efficiency of a mixer. The excellent mixing inner core structure can make various fluids flow in the mixer. Under the action of the mixing unit of the mixer, mov...

AI Technical Summary

Problems solved by technology

If it is necessary to increase the combined strength of the mixing unit, it may be necessary to increase the welding area between the blades, or add some reinforcement structures, which obviously increases the processing difficulty of the mixing unit and reduces the flow cross section inside the mixer , which reduces the mixing efficiency of the mixer
