The utility model discloses a kind of magnetic drive grid ring microchannel liquid mixing device, it relates to a kind of liquid mixing device.The utility model uses modularization magnetic drive, pre-dispersion and shearing breakage are carried out to premixed liquid by grid structure, three-stage Archimedes spiral microchannel design is adopted in mixed channel, wherein inlet passage layer is configured annular average arrangement rectangular cross section microchannel, secondary mixing passage layer adopts spiral channel from circle center to outer periphery, tertiary mixing passage layer is the spiral channel of circumferential flow to circle center, through the synergistic effect of eddy current and shear force induced by spiral gradually expanding structure, realize two liquid efficient mass transfer.The utility model has the advantages of modularization easy disassembly replacement and active mixing, through the synergistic effect of magnetic drive multistage mixing unit, significantly improve the dispersion uniformity and mixing efficiency of material in microchannel, suitable for fine chemical and biological pharmaceutical technology field etc.

This utility model relates to the field of proportioning device technology and discloses an integrated gas proportioning, mixing, and filtering device, including a proportioning cabinet and threaded pipe fittings. The proportioning cabinet has a mixing chamber inside. A mixing box is fixedly installed on the inner front wall of the mixing chamber near the upper side. An air inlet pipe is connected and fixedly installed on the lower right side of the mixing box, and an air inlet pipe is connected and fixedly installed on the upper left side of the mixing box. A rotating rod is rotatably installed in the middle of the inner front wall of the mixing box. A vortex fan blade is fixedly sleeved on the rotating rod near the front side. An air outlet pipe is connected and fixedly installed in the middle of the lower side of the mixing chamber. A metal double cylinder is slidably installed inside the air outlet pipe. This device actively mixes different gases by rotating the vortex fan blade. Combined with staggered baffles to change the airflow direction, air vents to increase airflow complexity, and the convective mixing effect generated by the rotating mixing fan blades colliding with the gas, it achieves rapid and uniform mixing.

FIELD: pipeline transport.SUBSTANCE: invention can be used to introduce a homogeneous and structurally stable drag-reducing additive into an oil pipeline or oil product pipeline. The problem solved in the development of the claimed invention, without reducing the efficiency of mixing the drag-reducing additive, is to eliminate the effect of its foaming and its polymerisation and deposition of polymer on the internal walls of the tank. Tank for producing and storing drag-reducing additive is made in a vertical design in the form of a cylindrical shell with a conical bottom, a cover and with an installed mixing device consisting of a shaft with an electric motor. Blades are installed on the shaft. The tank inlet is an inlet nozzle located in the cover, and the outlet is an outlet nozzle located in the conical bottom. Mixing device is made in the form of a vertical shaft with horizontally installed blades with an angle of attack of 0°, at the ends of which conical impellers are installed. Radial part of the blades can be made in the form of a rod. The execution of horizontally installed blades with an angle of attack of 0° prevents active mixing and foaming around them.EFFECT: invention can be used both in the production of new tanks and in the reconstruction of those in operation at oil and gas industry enterprises in installations for introducing drag-reducing additives into an oil pipeline.2 cl, 3 dwg
