Fluid mixing mechanism

Abstract

The invention provides a fluid mixing mechanism. In a working area, the fluid mixing mechanism is used as a communicating hole for a second fluid to enter a connecting channel of a first fluid, and isa narrow and long gap hole in shape, so that the second fluid is guided into the first fluid in a large range, and the mixing efficiency between the first fluid and the second fluid is improved; andmeanwhile, the countercurrent state that the first fluid is opposite to the second fluid source direction can be avoided.

Description

technical field [0001] The invention relates to fluid mixing technology, in particular to a fluid mixing mechanism. Background technique [0002] In the U.S. No. 6284810 patent, it is disclosed that between the foaming agent supply channel and the vertically corresponding extruding cylinder, a plurality of independent holes are set to communicate with the foaming agent supply channel and the inner space of the extruding cylinder, and the extrusion process is carried out by the screw. When the cylinder rotates, each hole is rapidly blocked and released by the screw teeth to increase the mixing speed between the foaming agent and the molten polymer raw material fluid in the extrusion cylinder. [0003] In order to make the hole completely blocked by the thread of limited thickness in the previous patent, it is necessary to limit the diameter of the hole to be within the thickness range of effective contact of the thread, so as to achieve fast closing and opening of the hole, b...

AI Technical Summary

Problems solved by technology

[0003] In order to achieve that the hole can be completely blocked by the thread of limited thickness, the diameter of the hole must be limited within the thickness range of effective contact of the thread. It can achieve fast closing and opening of the pores, but in this way, the distribution area of ​​the pore size and the pores is limited, and the mixing area and efficiency are also limited.
