Problems solved by technology
Pipeline static mixer equipment is low in cost and low in mechanical loss, but requires a large pipeline arrangement space, long process and large fluid resistance, and has high requirements for flow rate. From the perspective of mixing effect, the longitudinal mixing and crushing mixing of fluids are weak. Not entirely suitable for applications requiring complete molecular scale level mixing

Abstract
The invention provides a squirrel-cage type supergravity mixer. The supergravity mixer mainly comprises a mixing chamber, feeding pipes, feeding distribution pipes, a nitrogen sealed pipe, a discharge pipe, an equipment supporting stage, a squirrel-cage rotator, a motor, a transmission shaft, a deceleration strip mechanism, an upper bearing box, a lower bearing box and a cooling fan. According to the supergravity mixer, unique arrangement and a structural design of the feeding pipes are adopted and biphase liquids are subjected to efficient primary macromixing. By combination of the organically distributed feeding distribution pipes and utilization of the supergravity field in the squirrel-cage rotator and high-speed shearing of a winding screen mesh, fluid molecule diffusion and interface mass transfer are enhanced and secondary microscopic mixing of the fluid is fully achieved. The squirrel-cage type supergravity mixer is reasonable in design, compact in structure, low in energy consumption and simple in operation technology, and can achieve rapid and efficient mass transfer between liquid phases. Deep mixing in the molecule dimension grade is reached. Liquid-liquid mixing and reaction requirements in the chemical engineering industry, the pharmaceutical industry, and the like are satisfied.
Description
technical field [0001] The invention relates to a device for quickly and efficiently mixing two liquid phases, more specifically, a squirrel-cage supergravity mixer, through which one liquid phase can be quickly added to another liquid phase , and efficiently mix the two liquid phases. The squirrel-cage high-gravity mixer is especially suitable for liquid-liquid mixing and reaction in chemical industry, biotechnology, pharmaceutical, environmental protection and other industries. Background technique [0002] Liquid-liquid mixing and reaction systems widely exist in industrial processes such as chemical industry, pharmaceuticals, biotechnology, and environmental protection, and good microscopic mixing is a necessary condition for such processes. For example, in the process of using liquid-liquid two-phase co-precipitation to prepare solid particles, the mixing effect of liquid-liquid two-phase directly affects the shape, particle size, and particle size distribution of the ...
