Abstract (en)

The present invention provides a static fluid mixer which is remarkably easily assembled, facilitates machining of the inner circumferential surface of the casing to reduce production costs, prevents vibrations of mixing elements, and further improves insufficiency in mixing due to short-circuited flows generated by leakage. The mixing assembly element 5 internally incorporated in the casing 4 is constructed of an annular sealing unit 8 formed of a resilient material, and mixing elements 9, whereby the annular sealing unit 8 forms a cylindrical body by a resilient material with the outer diameter which can be inserted into the casing 4, flanges are formed inward of both ends of the cylindrical body, and the mixing element 9 is constructed so that two large and small disks arrayed in a plurality and having small chambers formed at the front thereof are provided as a set and these are internally incorporated in the annular sealing unit 8 by causing these to overlap each other concentrically. <IMAGE>
