[0027] Embodiment 1

[0028] Please refer to Figures 1-4 , the technical solution of a ball mill tank for glass powder grinding and separation provided in this embodiment is as follows: including:

[0029] Tank body 1, with a first cover 2 and a second cover 3 detachably provided at both ends of the tank body 1 respectively;

[0030] Separation auxiliary part 4, configured at the end where the second cover 3 is located, and one end of the separation auxiliary part 4 penetrates through the second cover 3 and is placed in the tank body 1;

[0031] Separation component, configured in the tank body 1 and detachably connected to the separation auxiliary part 4;

[0032] Glass powder cleaning part 7, arranged around the separation component.

[0033] Preferably, this design mainly includes a jar for loading zircon beads and large particles of glass powder to be ground. The jar includes a tank body 1, both ends of the tank body 1 can be opened, and a first cover 2 and a second cover 3 are respectively provided. The cover and the tank body 1 can be connected by threads or other means; it also includes a separation device for separating zircon beads and large particles that are not completely ground, mainly composed of a separation auxiliary part 4 penetrating through the second cover 3 and a separation component arranged at one end of the separation auxiliary part 4 located in the inner cavity of the tank.

[0034] Specifically, the separation auxiliary part 4 is a support rod, the separation auxiliary part 4 is coaxially arranged with the second cover 3, a handle is provided at the end of the separation auxiliary part 4 located outside the second cover 3, and an external thread is provided at the end of the separation auxiliary part 4 arranged in the tank body 1.

[0035] Preferably, the material of the separation auxiliary part 4 is a hard metal material.

[0036] Specifically, the separation component includes a zirconia bead separation disc 5 and a particle size separation disc 6; the outer diameters of the zirconia bead separation disc 5 and the particle size separation disc 6 are the same, and the zirconia bead separation disc 5 is disposed on a side of the particle size separation disc 6 away from the first cover 2;

[0037] A hole groove is provided at the center of the separation component, and an inner thread matching the external thread is provided on the inner wall of the hole groove.

[0038] Preferably, the outer diameters of the zirconia bead separation disc 5 and the particle size separation disc 6 are slightly smaller than the inner diameter of the tank body 1 to provide a receiving space for the installation of the brush bristles.

[0039] Specifically, a plurality of zirconia bead separation holes are uniformly provided on the disc body of the zirconia bead separation disc 5, and the diameter of the zirconia bead separation holes is smaller than the diameter of the zirconia beads.

[0040] Specifically, a plurality of mesh holes are provided on the disc body of the particle size separation disc 6, and the aperture of the mesh holes is smaller than the diameter of the zirconia bead separation holes.

[0041] Preferably, there will be a situation where the grinding is not sufficient during the process of grinding glass powder with zirconia beads, so there will still be some large-particle glass powder.

[0042] Specifically, the glass powder cleaning member 7 is a brush bristle.

[0043] The working principle or working process of a ball mill tank for glass powder grinding and separation provided by the present utility model is as follows:

[0044] When grinding is required, open the second cover 3. After putting zirconia beads and glass powder to be ground into the inner cavity of the tank body 1 and then covering the second cover 3, place the ball mill tank on the grinding machine for grinding. The large-particle glass powder is ground into powder by the rolling action of the zirconia beads. Note: The separation auxiliary member 4 is not installed during grinding.

[0045] When discharging is required, first invert the ball mill tank, that is, the first cover 2 is located above. Open the first cover 2 and install the separation component on the separation auxiliary member 4 (the particle size separation disc 6 is located above the zirconia bead separation disc 5). Then cover the second cover 3, turn the ball mill tank over and gently loosen the first cover 2, hold the handle and pull out the first cover 2. The separation auxiliary member 4 takes out the large-particle glass powder and zirconia beads from the ball mill tank, realizing the convenient separation of the glass powder and the zirconia beads. In addition, by stretching the second cover 3, the glass powder attached to the tank wall can be effectively recovered and efficiently utilized by the brush bristles.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
