As a further improvement of the utility model, the upper surface of the stirring paddle blade is provided with a plurality of guide strips, the guide strips are arc-shaped, and each guide strip is concentrically arranged around the stirring shaft.

As a further improvement, the stirring paddle is circular, and the circular stirring paddle is favorable for the material to be mixed in the axial direction of the stirring paddle.

As a further improvement of the utility model, the stirring shaft is a hollow shaft, the lower end of the hollow shaft is sealed, and the upper end of the hollow shaft is opened; the stirring paddle is a hollow paddle, and holes are uniformly formed in the bottom of the stirring paddle; the hollow cavity of the stirring shaft is communicated with the hollow cavity of the stirring blade.

As a further improvement of the utility model, the stirring paddle blades are inclined to the stirring shaft, so that the materials can gradually move upwards to enhance the mixing.

As a further improvement of the utility model, the stirring paddle and the stirring shaft form an included angle of 45-85 degrees.

The utility model has the advantages that:

1. the utility model provides a stirring paddle leaf along the eccentric setting of (mixing) shaft and be the heliciform structure and arrange, use the utility model discloses during the stirring, the material can be along stirring paddle leaf spiral shell screwing in, realizes axial motion, can realize the material along the radial and axial simultaneous movement of (mixing) shaft, promotes the mixing degree between the solid-liquid material in the material axial and radial motion's process, increases solid-liquid area of contact, shortens reaction time, improves the leaching rate;

2. the utility model designs the arc-shaped guide strip on the stirring paddle blade, so that the material on the stirring paddle blade can realize radial turbulent motion under the action of the guide strip, thereby being more beneficial to uniformly stirring the material;

3. the utility model designs the communicated cavity in the stirring shaft and the stirring paddle blade, and can add the leaching solution through the cavity, the leaching solution firstly enters the cavity of the stirring shaft, then sequentially enters the cavity of the stirring paddle blade communicated with the cavity, and finally flows out from the hole at the bottom of the stirring paddle blade, so that the leaching solution simultaneously acts on all materials in the stirring tank, the reaction time is further shortened, and the leaching rate is improved; therefore, the utility model has wider application range, can be applied to the leaching operation of low liquid-solid ratio and high viscosity serous fluid, and can also be applied to the leaching operation of high liquid-solid ratio and low viscosity materials;

4. the utility model discloses simple structure, the operation is reliable, and the practicality is strong.
