Description

Technical Field

[0001] The utility model relates to the technical field of static mixers, in particular to a multi-tube static mixer. Background Art

[0002] A static mixer is a highly efficient mixing device without moving parts. Its basic working mechanism is to use a mixing unit fixed in a tube to change the flow state of the fluid in the tube, so as to achieve good dispersion and sufficient mixing between different fluids. This device is widely used.

[0003] A Chinese patent discloses a static mixer with a publication number of CN220425035U, and the application date is 2023.06.29. The patented technology is provided with a fixing frame, an arc mounting plate, a first positioning rod, a second positioning rod, a static mixer blade, a first mounting block, a second mounting block, a positioning through-hole external thread and a fastening nut. The first positioning rod can be inserted into the positioning through-hole provided in the first mounting block, and the second positioning rod can be inserted into the positioning through-hole provided in the second mounting block. The static mixer blade and the fixing frame are limited and fixed to prevent the fixing frame from rotating, and multiple static mixer blades can be fixed on the fixing frame in sequence. After the static mixer blades are installed, the fastening nut is screwed into the external thread so that the fastening nut abuts against the static mixer blade. The multiple static mixer blades are fixed to the outside of the first positioning rod and the second positioning rod by using the arc mounting plate and the fastening nut, which is convenient for taking out together during cleaning and reducing the difficulty of disassembly.
