Mixing element for static mixer, static mixer and method of production of such a mixing element

摘要

A mixer insert (2) for a static mixer, extending in a longitudinal direction (LD) (L) and having cross-pieces transverse to the LD and at least two long pipes (2f) extending in the LD, consists of base elements (2a - 2d) adjacent to each other in the LD, each including a long pipe. The base elements and their pipes are mutually located to form a long pipe extending over the whole length of the insert, with adjacent base elements permanently connected together at least via the pipe. Independent claims are included for: (1) a static mixer (1), comprising a mixer insert (2) as above, within a container; and (2) a method for producing the mixer insert in the form of monolithic component, by locating base elements (2a - 2d) of readily fusible material in contact with each other in a longitudinal direction (LD); encapsulating the base elements; removing the base elements by fusing, so that cavities are formed where the base elements had been; feeding solidifiable liquid material into the cavities; and forming the monolithic mixer insert having the shape of the original base elements.
