Description

Coating stirring device

Technical Field

The utility model relates to a coating stirring field, in particular to coating stirring device.

Background

The paint stirring tank is an extremely important production device in the paint production process, and the uniformity of paint stirring directly influences the quality of paint. In the paddle type stirrer, the angle between the paddle and the horizontal plane can directly influence the stirring effect, and the paddles with different angles rotate to enable fluid in the stirring kettle to generate axial flow and radial flow with different strengths, so that the mixing effect of solid and liquid in the stirring kettle is influenced, the circulating flow field range near the paddle is gradually reduced along with the increase of the angle of the paddle, the circulating flow field range around the paddle with 15 degrees is widest, and the circulating flow field range around the paddle with 90 degrees is smallest. Meanwhile, two obvious circulating flow fields exist on two sides of the bottom of the stirring kettle, the ranges of the two circulating flow fields are gradually increased along with the lifting of the angle between the paddle and the horizontal plane, solid particles at the bottom of the stirring kettle are conveyed to the upper part of the paddle by axial flow generated by the stirring paddle, and the axial flow strength generated by the paddle with the angle of 15 degrees is smaller than that generated by other paddle angles, so that the solid content of the upper half part of the stirring kettle is less. The axial flow strength provided by the blades and the circulating flow range around the blades are comprehensively considered, the 30-degree blades provide stronger axial flow compared with the 15-degree blades, and the flow field range around the blades is larger compared with other blades with larger angles.

The angle between the paddle and the horizontal plane of the traditional stirring device is mostly fixed and cannot be adjusted according to actual production requirements, so that the usability of the traditional stirring device is limited.
