FIG. 1 is a view showing an elevation of a dispersion cylinder of an ink dispersion stirring apparatus according to an embodiment of the present invention;

fig. 2 is a plan view of a dispersion cylinder of the ink dispersion stirring apparatus according to the embodiment of the present invention.

Detailed Description

This embodiment provides kinds of ink dispersion stirring devices, as shown in fig. 1, which includes a cylinder for containing ink and a stirrer, wherein the cylinder includes a vertical cylinder 3 and a lower conical cylinder 4, and the stirrer is a revolving structure and includes a dispersion shaft 1, a dispersion disc 2, a plurality of vertical cylinder spoilers 5 and a plurality of lower conical cylinder spoilers 6.

The lower conical cylinder 4 is arranged at the bottom of the vertical cylinder 3, the projection of the lower conical cylinder 4 is annular, the outer circle edge, namely the upper edge of the lower conical cylinder 4 is connected with the inner wall of the vertical cylinder 3, the inner circle edge, namely the bottom edge of the lower conical cylinder 4 is connected with the inner bottom surface of the vertical cylinder 3, the plurality of lower conical cylinder spoilers 6 are uniformly arranged on the upper surface of the lower conical cylinder 4 along the circumferential direction, the plurality of vertical cylinder spoilers 5 are of a cylinder structure with a V-shaped cross section and correspond to the plurality of lower conical cylinder spoilers 6 , each vertical cylinder spoiler 5 is correspondingly arranged between the outer ends of the lower conical cylinder spoilers 6 and the inner wall of the vertical cylinder 3, and the outer side edge of each vertical cylinder spoiler 5 is attached to the inner wall of the vertical cylinder 3 and reaches the top of the inner wall of the vertical cylinder 3.
