[0003] The object of the present invention is to provide a static mixer for liquids with more than two components in view of the above disadvantages. The carbon dioxide combined foaming agent is made of chemical substances with more than two components, and carbon dioxide and alcohols or alkanes are used as the foaming agent ratio. In order to overcome the problem of insufficient mixing of different components of chemical substances in the production process, the present invention uses the unique structure of each mixing unit fixed in the tube body to change the flow state of the liquid in the tube body to achieve different liquid between good dispersion and thorough mixing

The invention provides a static mixer for liquid containing more than two ingredients, which relates to a small high pressure resistant tubular liquid static mixer which is formed by more than three groups of mixing units inside, and is particularly applicable to mixing of carbon dioxide composite foaming agent in production of carbon dioxide XPS polystyrene extruded sheet material. The static mixer comprises a tube body, a tight nut and mixing units; wherein the mixing units are arranged in the tube body; each mixing unit consists of two crossly distributed spiral flow deflectors, two oblique splitters, two homogenization splitting tubesheet and a mixing neutral block in sequence; the spiral flow deflector is a slabbing spiral steel sheet; the oblique splitter consists of a plurality of metal sheets which have irregular surfaces which are bended by machine and packed together by thin steel wires; the homogenization splitting tubesheet is a round thin steel sheet, and a plurality of round through holes with the same size are well-distributed on the round thin steel sheet; the mixing neutral block is a cylinder, a through hole is arranged inside the cylinder, and two ends of the cylinder are provided with conical inclined planes.
Description
technical field [0001] The static mixer for liquid with more than two components of the present invention relates to a small high-pressure resistant tubular liquid static mixer, which is composed of more than three sets of mixing units inside. It is especially suitable for the mixing of carbon dioxide combined foaming agent foaming agent in the production of carbon dioxide XPS polystyrene extruded board, and can also be used for mixing different components of foaming agent. Background technique [0002] In the XPS extrusion industry, the mixed and homogenized carbon dioxide combined foaming agent used for fluid materials is composed of more than two components of chemical substances, and is made of carbon dioxide and alcohols or alkanes as a foaming agent. However, in the previous production process, when the foaming agent combined with carbon dioxide was used as the foaming agent, it was impossible to mix the foaming agent completely and uniformly before injecting the mater...
