[0019] The claims of the present invention will be further described in detail below with reference to specific embodiments and figures. Obviously, the described embodiments are only a part of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figure 1 - Figure 2 As shown, the present invention provides an embodiment of a grinding and dispersing wheel.

[0023] The grinding and dispersing wheel includes a grinding and dispersing wheel body 1. The grinding and dispersing wheel body 1 is uniformly provided with variable radial blind holes 11 connected by a first axial hole 12. A variable radial through hole 13 is provided between two adjacent variable radial blind holes 11. The variable radial through hole 13 is connected to the separation channel formed by the central through hole 10 provided by the grinding and dispersing wheel body and the outside of the grinding and dispersing wheel body 1. During grinding, the variable radial through hole 13 is open, and when it stops, the variable radial through hole 13 becomes smaller or closes.

[0024] Specifically, the variable radial blind hole 11 includes a fixed strip 110 and a movable strip 14 that is rotatably connected to the grinding and dispersing wheel body and cooperates with the fixed strip 11 in the radial direction to form a closed state. When the movable strip 14 rotates to its maximum angle, it contacts the fixed strip 110 of the adjacent variable radial blind hole 11, causing the variable radial through hole 13 to close or become smaller.

[0025] In the initial state, because the variable radial blind hole 11 has a large opening, the slurry in the grinding cylinder is used as a lower, so that the radial blind hole 11 opening gradually increases, and then the movable strip 14 rotates in the direction of the adjacent fixed strip, thereby closing the variable radial through hole 13, thereby ensuring that the material does not enter the separation channel and is discharged during the next start. When the variable radial through hole 13 is small, the slurry is also difficult to enter the smaller variable radial through hole 13 due to the tension between the slurry, thereby also achieving the above purpose.

[0026] Because the variable radial blind hole and the variable radial through hole can be uniformly arranged on the body, the processing difficulty can be reduced, the dynamic balance can be ensured to be better, and the service life can be improved.

[0027] In the embodiment, the variable radial blind hole 11 increases from inside to outside, that is, in a horn structure. The fixed strip 110 and the movable strip 14 are respectively in an arc structure, and have a better acceleration effect on the slurry during dispersion.

[0028] As shown in Figure 3 The present application also provides a second example, that is, a second axial hole 15 is arranged in the variable radial through hole. The second axial hole 15 is located at a distance greater than the first axial hole 12 from the center through hole 10, and when the movable strip is maximally rotated, the second axial hole 15 is located in the radial blind hole 11 or is blocked by the movable strip 14. Other structures are the same as the above embodiment, and will not be described again.

[0029] As shown in Figure 1 The present application also provides a grinding system, which comprises a grinding and dispersing wheel, and the grinding and dispersing wheel comprises a grinding and dispersing wheel body 1, the grinding and dispersing wheel body 1 is uniformly provided with a variable radial blind hole 11 communicated with a first axial hole 12, a variable radial through hole 13 is arranged between two adjacent variable radial blind holes 11, the variable radial through hole 13 is communicated with a separation channel formed by a center through hole 10 arranged on the grinding and dispersing wheel body and an outside of the grinding and dispersing wheel body 1, the variable radial through hole 13 is conducted during grinding, and the variable radial through hole 13 is small or closed during stopping.

[0030] Specifically, the variable radial blind hole 11 comprises a fixed strip 110 and a movable strip 14 rotatably connected with the grinding and dispersing wheel body and cooperating with the fixed strip 11 in the radial direction to form a closed state, and the movable strip 14 is in contact with the fixed strip 110 of the adjacent variable radial blind hole 11 at a maximum rotation angle, so that the variable radial through hole 13 is closed or small.

[0031] In the initial state, due to the large opening of the variable radial blind hole 11, the slurry inside the grinding cylinder causes the opening of the radial blind hole 11 to gradually increase, thereby causing the movable bar 14 to rotate towards the adjacent fixed bar, thus closing the variable radial through hole 13. This ensures that the material does not enter the separation channel and is discharged during the next startup. When the variable radial through hole 13 becomes smaller, due to the tension between the slurry particles, it is also difficult for the slurry to enter the smaller variable radial through hole 13, thus achieving the above objective.

[0032] Since the variable radial blind holes and variable radial through holes can be uniformly arranged on the body, the processing difficulty can be reduced, better dynamic balance can be ensured, and service life can be improved.

[0033] In this embodiment, the variable radial blind hole 11 increases in size from the inside out, i.e., it has a trumpet-shaped structure. The fixed strip 110 and the movable strip 14 are respectively arc-shaped, which have a better accelerating effect on the slurry during dispersion.

[0034] In this embodiment, the variable radial blind hole 11 increases in size from the inside out, i.e., it has a trumpet-shaped structure. The fixed strip 110 and the movable strip 14 are respectively arc-shaped, which have a better accelerating effect on the slurry during dispersion.

[0035] like Figure 3 As shown in Figure 5, the present invention also provides a second embodiment, wherein a second axial hole 15 is provided within the variable radial through hole. The distance between the second axial hole 15 and the central through hole 10 is greater than that of the first axial hole 12, and when the movable bar rotates to its maximum angle, the second axial hole 15 is located in the radial blind hole 11 or blocked by the movable bar 14. Other structures are the same as those described above and will not be repeated.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions may cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
