[0054] The specific embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0055] Example one:

[0056] As shown in the figure, the initial shape of the dispersion rod 3 is set to be cylindrical, providing a design and processing method of a frame type dispersion disc. Figures 1-5 The structure of the frame type dispersion disc is as follows: a thin connecting plate 2 in the shape of a hexagonal star, a through hole is opened in the middle of the connecting plate 2, the through hole is matched and installed with a hollow cylindrical shaft sleeve 1, the side of the shaft sleeve 1 is uniformly provided with dispersion rods 3 along the outer circumferential surface of the shaft sleeve 1, the sharp corners of the connecting plate 2 are provided with connecting grooves, and the dispersion rods 3 are fixed with the connecting plate 2 through the connecting grooves.

[0058] The value range of the dispersion area ratio α is 10%-15%, and the value range of the effective dispersion area particle unit distance speed change difference β is 40m / s-80m / s. The dispersion area ratio α represents the ratio between the effective dispersion area volume of the dispersion disc and the effective volume of the dispersion equipment container. The larger the value of the dispersion area ratio α, the larger the dispersion area of the dispersion disc, the wider the dispersion range, that is, the higher the dispersion efficiency. The dispersion area ratio α of the traditional single dispersion disc is about 5%; the effective dispersion area particle unit distance speed change difference β represents the ratio between the difference between the minimum speed and the maximum speed of the peripheral particles in the effective dispersion area of the dispersion disc during dispersion operation and the spatial distance between the two particles. The smaller the value of the effective dispersion area particle unit distance speed change difference β, the more obvious the influence of the dispersion disc on the surrounding dispersion particles during dispersion, which can provide more powerful dispersion effect, and the higher the dispersion efficiency. Under the same conditions, the effective dispersion area particle unit distance speed change difference β of the traditional dispersion disc is about 90m / s or more, that is, the dispersion speed of the traditional dispersion disc per unit time decays significantly.
