CHARGED ARTICLE FIXING STRUCTURE, CHARGED ARTICLE FIXING METHOD, STATIC MIXER, AND METHOD FOR ASSEMBLING STATIC MIXER

摘要

PROBLEM TO BE SOLVED: To make it possible to simply fix a charged article such as a mixed element into a pipe body.SOLUTION: A charged article fixing structure, in which a mixed element 12 as a charged article is fixed into a pipe body 13 thereby constituting a static mixer 11, is equipped with a stationery member 14 having a coil spring shape. The stationery member 14 has a contact part 41, which contacts the mixed element 12, on an end surface in a longer direction, and a pressure contact part 42, which pressure-contacts an inner peripheral surface of the pipe body 13, on an outer peripheral surface. Further, an outer diameter of the pressure contact part 42 is larger than an inner diameter of the pipe body 13. After twisting and contraction-deforming the stationery members 14, the stationery members 14 are inserted into the pipe body 13, and are located on both sides of the mixed element 12 which has been previously inserted into the pipe body 13, whereby the mixed element 12 is fixed.
