A large static mixer

Abstract

The invention provides a large-scale static mixer, which includes a pipeline and a mixing unit placed in the pipeline, and the two ends of the pipeline are open; the mixing unit includes four first to fourth blades in the shape of circular arcs ; The first blade and the second blade are relatively intersected, the axis of the intersection point is horizontal, the first blade is angled downward around the axis of the intersection point, and the second blade is angled upward around the axis of the intersection point; the third blade and the fourth blade are opposite Cross setting, the axis of the intersection point is vertical, the third blade is angled to the right around the axis of the intersection point, and the fourth blade is angled to the left around the axis of the intersection point; the rear end of the first blade is connected to the board surface of the third blade, The rear end of the second blade is connected to the board surface of the fourth blade, the front end of the third blade is connected to the board surface of the second blade, and the front end of the fourth blade is connected to the board surface of the first blade. The invention increases the overall structural strength of the mixer with a special combination of blades, and the reasonable overall structure makes it have 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
