[0014] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] like Figure 1-2 As shown, a stirring device of a batch mixing equipment of the utility model comprises a stirring motor 1, a reducer 2, a limiting flange 3, a stirring shaft 4, a stirring blade assembly 5, a stirrer support 6 and a copper sleeve 8. The flat key shaft of the stirring motor 1 is installed together with the flat key groove of the reducer 2. The reducer 2 reduces the output speed of the stirring motor 1. The stirring shaft 4 is connected to the reducer 2 through a flat key to transmit the output torque of the stirring motor 1 to the stirring shaft 4. The stirring shaft 4 limits the stirring shaft 4 through the limiting flange 3 to prevent the axial movement during operation; the stirring blade assembly 5 is connected to the stirring shaft 3 through a flat key to transmit the torque of the stirring shaft 4 to the stirring blade assembly 5, driving the blades on the stirring blade assembly 5 to rotate, thereby driving the liquid in the batch mixing tank to be mixed evenly. The top of the stirring shaft 4 is fixed in the stirrer support 6, and the stirrer support 6 is equipped with a copper sleeve 7. The copper sleeve 7 separates the stirring shaft 4 from the stirrer support 6 to reduce wear.
