[0023] It should be noted that when a device is considered to be "connected" to another device, it may be directly connected to the other device or there may be an intermediate device at the same time. The terms "inside", "top", "upper", "lower", "upper", "lower" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] A grinding machine dispersion wheel, characterized in that it includes a disc body 100, on which a plurality of isolation columns 200 are arranged, and the plurality of isolation columns 200 are arranged on the same circumference. Under high-speed rotation, the isolation columns 200 form a large and a small, one inside and one outside dual-channel isolation membrane, which can prevent the random interaction between the internal and external media, forming an internal turbulent zone and an external turbulent zone, so that the turbulence is orderly and controllable, achieving the purpose of isolation and order. The isolation columns 200 penetrate the disc body 100, forming an upper isolation column 200 on the upper side of the disc body 100, and forming a lower isolation column 200 on the lower side of the disc body 100.

[0027] Preferably, the process of the dispersion wheel is as follows: prepare a plurality of isolation columns 200, the isolation columns 200 are cylindrical, each isolation column 200 is of equal size, and both ends of the isolation columns 200 are polished into rounded corners; prepare a round cake, i.e., a disk body 100, locate the installation position of the isolation column 200 along the same circular trajectory of the disk body 100, mark each position, the distance between each position is equal, and make isolation holes at the marked positions, the size of the isolation holes is optimal for the isolation columns 200 to just pass through; install the prepared isolation columns 200 on the disk body 100 through the isolation holes, the upper part of the disk body 100 is the upper isolation column, and the lower part of the disk body 100 is the lower isolation column.

[0028] The height of the isolation column 200 is 0.5-1 times the thickness of the disk body 100, and the diameter of the isolation column 200 is 5%-20% of the diameter of the disk body 100. For example, when the disk body 100 has a diameter of 40 cm and a thickness of 5 cm, the height of the isolation column 200 is preferably 4 cm and the diameter is 2.5 cm.

[0029] The number of the isolation columns 200 is 2-12, preferably 4-8. Both ends of the isolation columns 200 are polished into rounded corners, which can improve the wear resistance of the isolation columns 200 and reduce the loss of the dispersion wheel. The isolation columns 200 are preferably rounded with a radius of 0-2 mm.

[0030] The disk body 100 is provided with an axial hole 300 at the center, and a key slot hole 400 is provided on the axial hole 300. The axial hole 300 is any one of polygonal, circular, square, and triangular. When the axial hole 300 is polygonal, square, or triangular, there may be no key slot hole 400. When the axial hole 300 is circular, there is at least one key slot hole 400. In the present invention, three key slot holes 400 are preferably provided.

[0031] The disc body 100 is provided with a plurality of medium through holes 500, and the medium through holes 500 may be evenly distributed or unevenly distributed, and there may be one or more medium through holes 500, and the medium through holes 500 may be any one of circular, square, sector-shaped, polygonal, elliptical, and rounded square. The medium through holes 500 are provided to allow the medium to flow fully in the grinder, and combined with the rotation of the dispersion disc, the material can be ground more evenly, thereby improving the grinding efficiency.

[0032] Preferably, the dispersion wheel is installed inside the grinder during use. When the dispersion wheel rotates at high speed, the grinding liquid forms two channels, inner and outer, large and small, on both sides of the dispersion wheel, so that the medium slurry cannot flow alternately at will, but can only circulate with the turbulent flow in the grinder. Therefore, the turbulence is orderly and controllable, achieving the purpose of isolation and control.

[0033] The above-described embodiments only express the way of equipment layout of the present application, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application; it should be pointed out that for ordinary technicians in this field, several adjustments and improvements can be made without departing from the concept of the present application, which all belong to the scope of protection of the present application; therefore, the scope of protection of the patent of this application shall be based on the attached claims.
