Static mixer suitable for additive manufacturing
A static mixer may include a housing having an inlet and an outlet. The static mixer may also include a mixing element arranged within the housing. The mixing element may include a plurality of blade disk pairs arranged in crisscrossing fashion, each blade disk, of the pairs of blade disks, comprising a plurality of parallel extending and spaced apart blades. In some examples, a blade disk may include a link connecting the end of each of the plurality of parallel extending and spaced apart blades. In some examples, the link may be a ring base. In other examples, the link may be a propped tie. Alternatively or additionally, a support perch may be provided for supporting a ring base of an adjoining module.
