Mechanical stirring bottom shaft assembly

Abstract

The invention relates to a mechanical stirring bottom shaft assembly, and belongs to the technical field of stirring equipment, the mechanical stirring bottom shaft assembly comprises a trough, a stirring main shaft and a bearing bush, the lower end of the stirring main shaft is detachably connected with a shaft sleeve, the shaft sleeve and the stirring main shaft are coaxially arranged, the bottom wall of the trough is fixedly connected with a support, the support is provided with a through fixing hole, and the axis of the fixing hole and the axis of the stirring main shaft are collinear; the shaft sleeve is conical, and the diameter of the lower end circle is larger than the diameter of the upper end circle, a conical hole is formed in the inner wall of the bearing bush, the original diameter of the lower end of the conical hole is larger than the diameter of the upper end of the conical hole, the bearing bush and the stirring spindle are coaxially arranged, the bearing bush is installed in the fixing hole, and the outer side wall of the shaft sleeve makes contact with the side wall of the conical hole. The conical shaft sleeve is matched with the bearing bush provided with the conical hole, and when abrasion occurs, the bearing bush moves downwards under the action of the gravity of the bearing bush, so that a gap between the bottom shaft assemblies is always kept, and it is ensured that the paddle does not swing after being abraded after being operated for a long time during stirring.

Description

technical field [0001] The invention relates to the technical field of stirring equipment, in particular to a mechanical stirring bottom shaft assembly. Background technique [0002] Most paddle agitators use a fixed straight cylindrical bottom bearing assembly to limit the swing of the agitation spindle during rotation. With the continuous expansion of the gap between the components, it will cause the stirring main shaft to swing during the rotation, resulting in shaking during operation. On the one hand, the shaking of the stirring during operation will cause serious wear of the bottom shaft parts. On the other hand, this out-of-limit shaking It will also cause an increase in the failure rate of the paddle stirring operation, which will not only damage the equipment, but also prolong the maintenance time and cause unnecessary manpower and material resources. [0003] Aiming at the problems existing in the prior art, we provide a mechanical stirring bottom shaft assembly. ...
