At present, the existing equipment mostly adopts a frame type stirrer to stir materials before reaction, and has the defects of high height of stirring blades, weak stirring force in the cross section direction of a cylinder body, low stirring efficiency and the like, so that the uniformity of the materials is influenced, and adverse effects are caused on the sufficient reaction of the materials.

SUMMERY OF THE UTILITY MODEL

The applicant provides a stirring structure for a reaction kettle aiming at the defects in the prior art, and solves the problem that the stirring force is not strong in the cross section direction of a barrel body of the reaction kettle, and the material is not uniformly mixed due to the fact that the stirring efficiency is low.

The utility model discloses the technical scheme who adopts as follows:

a stirring structure for a reaction kettle comprises a stirring body, wherein the stirring body is of a disc-shaped structure, a protrusion extends upwards from the middle of the upper surface of the stirring body, through holes are formed in the protrusion and the disc-shaped structure at the same time, a plurality of blades are uniformly arranged at intervals along the circumferential edge of the stirring body, the blades are obliquely clamped in the stirring body, the upper end surface and the lower end surface of each blade respectively extend out of the upper surface and the lower surface of the stirring body, and the outer end surfaces of the blades extend out of the circumferential outer ring of the; the stirring body is arranged on a rotating shaft inside the reaction kettle barrel, the upper end of the rotating shaft is connected with the driving device, the tail end of the rotating shaft penetrates through the through hole and extends out of the lower end of the stirring body, and the extending part is connected with a bearing assembly at the bottom of the barrel.

The further technical scheme is as follows:

the angle of inclination formed between the blades and the central axis of the stirring body is in the range of 45-60 degrees.

The outer end face of the blade extends out of the circumferential outer ring of the stirring body by 1/2-2/3 of the length of the blade.

The blades are rectangular, fan-shaped or oval.

The utility model has the advantages as follows:

the utility model has compact and reasonable structure and convenient operation, and optimizes the inclination angle of the blade relative to the stirring body and the depth of the blade clamped into the stirring body or the distance of the outer end surface of the blade extending out of the outer ring of the circumference of the stirring body by arranging a plurality of blades on the circumference of the stirring body through calculation and experiments, thereby selecting the blade parameter which can improve the stirring uniformity degree and the stirring efficiency of the material and save energy consumption, and greatly improving the mixing efficiency of the materials in the reaction kettle; the utility model discloses a small in size has strengthened the ascending stirring strength of reation kettle barrel cross section side, has shortened the mixing time before each material reaction in the reation kettle, has improved production efficiency.
