DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0023] Example 1

[0024] like Figures 1 to 4 As shown, this embodiment provides a separation mechanism, including a shell 1, a separation component 2 and a driving mechanism 3 for driving the separation component 2 to rotate, the separation component 2 is rotatably arranged in the shell 1, the separation component 2 includes a first separation shell 21, a second separation shell 22 and a transmission component 23 for outputting materials to the outside, the first separation shell 21 is located in the shell 1, the second separation shell 22 is installed in the first separation shell 21, the transmission component 23 is installed in the second separation shell 22, and a space 24 is left between the first separation shell 21 and the second separation shell 22; the side wall of the first separation shell 21 is provided with a plurality of first separation grooves 211, the side wall of the second separation shell 22 is provided with a second separation groove 221, the transmission component 23 is a hollow structure, and the side wall of the transmission component 23 is provided with a plurality of discharge grooves 231.

[0025] That is, when the utility model is in operation, the mixture of the material and the grinding medium enters the shell 1 from the bottom of the shell 1, and enters the second separation shell 22 through the bottom of the shell 1, and then the driving mechanism 3 drives the separation assembly 2 to rotate. Since the volume and mass of the grinding medium are greater than the volume and mass of the unit material, most of the grinding medium will be thrown out to the first separation shell 21 through the second separation groove 221 under the action of centrifugal force, and then thrown out to the shell 1 through the first separation groove 211. At the same time, the remaining grinding medium will be mixed with the material, and then separated by the second separation shell 22 and thrown out to the space 24 through the second separation groove 221, so that the material in the second separation shell 22 will not be mixed with the grinding medium, and the material will enter the transmission member 23 along the discharge groove 231, and be transmitted to the outside along the transmission member 23. At the same time, the remaining grinding medium will fall to the bottom of the shell 1 under the action of gravity and flow back to the grinding mechanism 6, realizing the effect of recycling the grinding medium.

[0026] Compared with the prior art which only has one separation component 2, the present invention cooperates with the first separation shell 21 and the second separation shell 22, that is, during centrifugal separation, most of the grinding media will be thrown out of the first separation shell 21 due to the centrifugal force, and the remaining grinding media will be thrown out into the space 24 between the first separation shell 21 and the second separation shell 22 under the action of centrifugal force, so that the remaining material can be transmitted to the outside through the transmission member 23, so that the material transmitted to the outside will not be mixed with the grinding media, thereby improving the purity of the material.

[0027] In this embodiment, the second separation groove 221 is a vortex groove, and the two ends of the second separation groove 221 are respectively connected to the inner and outer sides of the second separation shell 22. The material and the grinding medium are screened by the vortex groove, that is, only the grinding medium with a larger mass and part of the material will flow out to the space 24 along the vortex groove under the action of a larger centrifugal force, thereby achieving a screening effect.

[0028] In this embodiment, the first separation shell 21 is fixedly connected to the second separation shell 22, so that the first separation shell 21 and the second separation shell 22 rotate at the same angular velocity, thereby ensuring the synchronization of the movements and avoiding the influence of the separation effect due to the asynchronous movements.

[0029] In this embodiment, the driving mechanism 3 includes a transmission member 31, a transmission mechanism 32 and a driving motor (not shown in the figure), and the driving motor is connected to the transmission member 23 through the transmission mechanism 32, and the transmission member 31 is connected to the second separation shell 22. That is, the utility model works by generating centrifugal force by electric drive, and the transmission mechanism 32 is preferably a transmission belt transmission mechanism 32, which belongs to conventional means in the art and will not be described in detail here.

[0030] In this embodiment, the transmission member 31 is provided with a cavity 311, the transmission member 23 is located in the cavity 311, the transmission member 23 protrudes out of the cavity 311 from the top of the cavity 311, and a rotary joint 232 is provided on the top of the transmission member 23. The rotary joint 232 is reliably connected with the external storage tank, thereby ensuring the stability of transmission and avoiding leakage of materials.

[0031] Example 2

[0032] like Figure 5As shown, this embodiment provides a grinder, including a body 4, the body 4 is provided with a feeding mechanism 5 and a grinding mechanism 6, and the discharge end 61 of the grinding mechanism 6 is connected to the separation mechanism described in Example 1; specifically, the discharge end 61 of the grinding mechanism 6 is arranged at the top of the grinding mechanism 6, and the separation mechanism is installed at the top of the grinding mechanism 6. The grinding mechanism 6 preferably adopts a stirring method to drive the material and the grinding medium to continuously collide to achieve grinding, and through the stirring method, the mixture of the material and the grinding medium produced after grinding enters the separation mechanism through the top for separation, thereby achieving the separation effect.

[0033] Example 3

[0034] like Figure 6 As shown, the structure of this embodiment is substantially the same as that of the embodiment 2, and the main difference is that the discharge end 61 of the grinding mechanism 6 is arranged at one side of the grinding mechanism 6, and the separation mechanism is arranged obliquely at one side of the grinding mechanism 6. That is, the mixture of the material and the grinding medium enters the separation mechanism from one side of the grinding mechanism 6. As long as the mixture of the material and the grinding medium enters the separation mechanism from the bottom of the separation mechanism, it can be ensured that the separation mechanism performs sufficient separation before discharging and the grinding medium remains in the housing 1, thereby achieving the separation effect.

Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model.
