Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mixers, in particular to an SK type static mixer. Background Art
[0002] SK static mixer is composed of spiral plates twisted 180° or 270°. These spiral plates are installed in alternating left-hand and right-hand forms to achieve efficient mixing effect. Compared with other models such as SV static mixer, SK type may have a slightly worse mixing effect, but its advantage is that it is not easy to clog and is particularly suitable for processing materials containing impurities or dirty. This mixer is widely used in chemical, petroleum, pharmaceutical, food, fine chemical, plastic, environmental protection, synthetic fiber, mining and metallurgy and other fields, especially for processing medium with small flow and high viscosity. SK static mixer is suitable for various process such as mixing, reaction, extraction, absorption, injection molding, color matching, heat transfer, etc.
[0003] In the chemical, petroleum, pharmaceutical, food and other industrial processes, it is often necessary to mix two or more fluids to achieve reactions, heat transfer or extraction processes. Traditional dynamic mixing equipment such as agitators and impellers require external power sources, which not only consumes energy, but also has high maintenance costs and poses safety hazards to some flammable, explosive or high-viscosity media; therefore, we propose an SK static mixer to solve this problem.
