Improved curved blade type gas-liquid dispersion stirrer

An improved bent blade type gas-liquid dispersion stirrer comprises a disc, a plurality of rear bent blades are evenly distributed on the disc in the circumferential direction, auxiliary blades are connected to the bottoms of the rear bent blades, an acute angle is formed between each auxiliary blade and the horizontal line, and the auxiliary blades are additionally arranged on the basis of the rear bent blades. By utilizing the scheduling between the auxiliary blades and the horizontal line, the auxiliary blades are pressed down during operation, so that a medium has a downward flowing state during flowing, the problem that the radial flow type bent blade type blade gas-liquid dispersion stirrer does not have axial flow is solved, and the problem that the gas-liquid dispersion stirrer cannot be used for stirring the medium when the solid content of the medium is relatively large is solved. The problem of solid sinking caused by poor flow at the bottom is solved, and the mixing effect is greatly improved. 一种改
