2, being formed by upper part A and lower part B of venturi mixer of the present invention, the groove 7 cooperatively interacting and fin 8 push-pull configurations can make the circulation area of main flow fluid regulate according to the flowrate proportioning of main flow fluid and introducing fluid, and making venturi mixer at the main flow fluid of wider range and introducing fluid flow than under all has higher mixing efficiency.In the time that main flow fluid and introducing fluid flow are smaller, the main flow fluid circulation area of venturi mixer can be turned down, now main flow fluid still has higher flow velocity, ensures to carry out efficient blending with introducing fluid; Otherwise, in the time that main flow fluid and introducing fluid flow are larger, can tune up the circulation area of venturi mixer main flow fluid.Like this, venturi mixer can and be introduced fluid flow at the main flow fluid of wider range than under all has higher mixing efficiency.
3, on venturi mixer of the present invention, the height L1 of part A is less than the height L2 of lower part B, venturi mixer main flow fluid flow cross height can be decreased to L1 by maximum L1+L2, make the circulation area excursion of venturi mixer main flow fluid line wide, can be applicable to the main flow fluid of wider scope and introduce fluid flow proportioning.
4, venturi mixer of the present invention can be realized the online adjustment to venturi mixer main flow fluid circulation area; can be at any time according to the variation of main flow fluid and introducing fluid flow ratio in the use procedure of venturi mixer; in non-stop-machine situation, adjust venturi mixer main flow fluid circulation area, to realize the continuous production of fluid-mixing.
5, when the main flow fluid circulation area of venturi mixer is non-hour, be positioned at the flow-disturbing that the fin 8 of venturi mixer vertical inner wall and the jagged edge 10 of upper part A can strengthen venturi mixer, destroy the boundary layer of fluid, improve the mixing efficiency of venturi mixer, avoid occurring mixing uneven phenomenon.
6, the upstream of the downstream in the upstream of the main flow fluid flow ipe 1 of venturi mixer of the present invention, main flow fluid effuser road 5 and introducing fluid introducing pipeline 6 is all connected to the convenient crossover sub docking with typical circular pipeline, is convenient to the square venturi mixer that contains push-pull configuration of the present invention to be applied to round pipe compounder systems.
