According to the technical scheme of the invention: the utility model provides a helical ribbon stirring rake which characterized in that: including the (mixing) shaft, the circumferential surface interval of (mixing) shaft has the support horizontal pole that mutually perpendicular set up, a main spiral shell area blade is drawn forth respectively at the both ends that (mixing) shaft upper portion supported the horizontal pole, main spiral shell area blade from last down in proper order with each end connection who supports the horizontal pole, the lower extreme of two main spiral shell area blades extends to the lower extreme of (mixing) shaft respectively, bottom spiral shell area blade is connected to main spiral shell area blade bottom surface.
As a further improvement of the invention, the surface of the stirring shaft is provided with connecting pipes which are perpendicular to each other at intervals, the outer end of each connecting pipe is provided with a connecting flange, and the supporting cross rods are fixedly connected with the connecting flanges.
As a further improvement of the invention, the upper end part of the stirring shaft is fixedly provided with a shaft flange.
As a further improvement of the invention, the main helical ribbon blade is of a detachable structure.
As a further improvement of the invention, two main helical blades are symmetrically arranged around the stirring shaft.
As a further improvement of the invention, the outer spiral line of the bottom helical ribbon blade spirally rises according to the elliptic curved surface of the end socket.
The invention has the technical effects that: (1) the main helical ribbon blade of the stirrer is detachable, the upper end socket of the stirring tank and the barrel can be directly welded without adopting a large flange, and the stirring paddle can enter the reaction kettle through a manhole for installation, so that the manufacturing cost of the reaction kettle is reduced, and meanwhile, the sealing property of the tank body is improved.
(2) The support cross rods of the stirrer are connected by adopting sectional flanges, so that the installation is simplified, holes or key grooves do not need to be drilled on the shaft, and the strength of the stirring shaft is not reduced.
(3) The bottom paddle blade of the stirrer is an elliptical spiral curved surface, and forms a complete axial flow with the main helical ribbon blade during working, so that bottom materials are promoted to participate in the large circulation of the whole fluid, the mixing effect of the centering and high-viscosity fluid is better than that of a bottom anchor (frame) type paddle, and the poor mixing area at the bottom of the elliptical tank can be effectively eliminated.
