[specific embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.
Embodiment 1: the eddy current conveying technology is the principle of utilization eddy current, with the flow direction of medium by axially changing direction of rotation and axial screw into, make and in limited space, gas-liquid two-phase fully can be mixed, when medium is in the eddy current state, the layers of material of different specific weight transmission in the medium, the internal resistance when having significantly reduced medium motion.Simultaneously because sneaking into of gas makes viscous medium generation atomizing etc. reduce transport viscosity.And the eddy current attitude viscous medium in conveying can transmit better, and difficult the precipitation condensed, situation such as structure.The present invention adopts the principle of eddy-current technique, the utilization spiral vane, double feed inlet, single outlet, quicken mechanisms such as reducing, realize that eddy current mixes and the effect of inflation viscosity reduction, concrete structure is as follows: a kind of vortex gas-liquid blender, be connected in the fluid pipe, have a liquid-inlet 1 and mixed export 10 on the axial direction, also has a gas feed 5 in addition, described blender has the housing 7 of a cross section greater than pipe diameter, it is characterized in that, in described cavity, has stationary spindle 4, described stationary spindle 4 constitutes an annular housing 11 with external shell 7, link together by helical blade 6 between described stationary spindle 4 and the external shell 7, described annular housing is separated into helical pipe; Have an import deflection cone 3 at the front end of described stationary spindle 4 and corresponding liquid-inlet place, liquid outlet in the rear end of described stationary spindle 4 correspondence relatively symmetrically and have an outlet deflection cone 8.
