The internal cavity of the container 6 is used to place the raw materials, and a stirring shaft 2 is provided at the upper end of the center position thereof, and a stirring paddle 1 is installed at the lower output end of the stirring shaft 2. The stirring paddle 1 and the stirring shaft 2 are both provided with keyways, and the keyway positions correspond to each other, and the two are connected by a key. An adjustment gasket 3 is provided between the stirring paddle 1 and the shaft shoulder of the stirring shaft 2, and the output end of the stirring shaft 2 passes through the adjustment gasket 3 and the end hole of the stirring paddle 1 from top to bottom in sequence, and a gland 4 is provided at the lower end of the stirring shaft 2. Among them, the outer circle of the small end of the head of the gland 4 cooperates with the end hole of the stirring paddle 1, and the step surface of the gland 4 fits with the lower end surface of the end hole of the stirring paddle 1. The fastener 5 is tightened to make the gland 4 press the end surface of the stirring paddle 1, and the stirring paddle 1 is fixedly connected to the stirring shaft 2. When the equipment is working, the stirring device transmits power to the stirring shaft 2, drives the stirring shaft 2 to rotate, and the stirring paddle 1 rotates with the stirring shaft 2 to complete the stirring and dispersion of the materials in the container 6.

[0046] In order to achieve uniform stirring and dispersion of the material, a certain clearance requirement needs to be met between the stirring paddle 1 and the bottom surface 6a of the container and the inner wall 6b of the container body. Figure 2 As shown, the outer contour lines of the two blades of the stirring paddle 1 are on the same arc, and the outer diameter of the stirring paddle 1 is the arc diameter. During the stirring operation, the gap S between the stirring paddle 1 and the side wall of the container 6 is the distance from the outer circle 1c of the blade contour to the inner circle 6c of the container body. According to the structure and installation requirements of the stirring paddle 1 itself, the outer circle 1c of the blade contour of the stirring paddle 1 is precisely positioned, and the end hole 1a of the stirring paddle is processed by tooling to ensure the coaxiality of the end hole 1a of the stirring paddle and the outer circle 1c of the blade contour, so that the positions of the blades of the stirring paddle 1 are consistent with the gap of the inner wall of the container 6. The end face 1b of the stirring paddle is also finely processed to ensure that the end face of the stirring paddle 1 is flat and meets certain verticality requirements with the end face hole, so that the end face 1b of the stirring paddle is tightly fitted with the contact surface of the adjustment gasket 3 and the pressure cover 45 respectively, to ensure the gap L between the stirring paddle 1 and the bottom surface of the container 6.
