DETAILED DESCRIPTION

[0022] In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model is further explained below with the help of drawings and examples. It should be explained that the examples and features in the examples of the application can be combined with each other without conflict.

[0023] ​​​​Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figures 1-5 As shown, a grinding disc assembly for a cement vertical mill includes a housing 1. A lower grinding disc 11 is rotatably connected to the bottom of the housing 1. An upper grinding disc 4 is coaxially disposed above the lower grinding disc 11 and slidably connected to the inner wall of the housing 1. Lifting rings 12 are slidably installed inside both the upper and lower grinding discs 11. Several meshing teeth 13 are fixedly installed on the opposite faces of the two lifting rings 12 in a circular array around the central axis of the housing 1. Inclined rings 15 are fixedly connected to the opposite sides of the two lifting rings 12. In actual use, the upper grinding disc 4 and the lower grinding disc 11 rotate in opposite directions. Additionally, as shown... Figure 1 As shown, a pipe is provided on one side of the outer casing 1 for feeding. Therefore, when the raw material enters the outer casing 1 and is located between the upper grinding disc 4 and the lower grinding disc 11, the length of the surface meshing teeth 13 extending out of the upper grinding disc 4 and the lower grinding disc 11 is controlled by controlling the position of the lifting ring 12 within the upper grinding disc 4 and the lower grinding disc 11, depending on the size of the raw material. Since the upper grinding disc 4 and the lower grinding disc 11 rotate in opposite directions, the meshing teeth 13 can hold the raw material and drive it to rotate, using the friction between the raw materials to assist in grinding. The opposing surfaces of the upper grinding disc 4 and the lower grinding disc 11 and the several meshing teeth 13 inside them are slidably connected. The upper grinding disc 4 and the lower grinding disc 11 are both annularly arranged, and the inner sides of the upper grinding disc 4 and the lower grinding disc 11 are located in the opposite areas of the two lifting rings 12, and a rotating ring 3 is embedded and rotatably connected to each other. Several electric push rods 16 are fixedly connected to the side of the rotating ring 3, which are arranged in a circular array around the inclined ring 15. The telescopic ends of the several electric push rods 16 are installed with the inner side of the inclined ring 15. The inclined block 14 has an inclined surface that fits against the inclined ring 15. One side of the inclined block 14 is an inclined surface that fits against the inner side of the inclined ring 15, while the other side is a flat surface that slides through the inner walls of the upper grinding disc 4 and the lower grinding disc 11. In practical use, the movement of the inclined block 14 at its telescopic end is controlled by the extension and retraction of the electric push rod 16. Furthermore, the inclined block 14 in this design can be made of magnetic material, and the inclined ring 15 can be made of metal. The magnetic attraction between the metal and the magnetic material ensures the smooth flow of the inner surface of the upper grinding disc 4. The lifting ring 12 will not fall to the inner bottom surface of the lower grinding disc 11 under the action of gravity, causing all the meshing teeth 13 on its surface to extend out of the upper grinding disc 4. By utilizing the contact between the inclined side of the inclined block 14 and the inner inclined surface of the inclined ring 15, when the inclined block 14 is close to the inner wall of the outer shell 1, the inclined ring 15 drives the lifting ring 12 to descend in the upper grinding disc 4 and rise in the lower grinding disc 11. When the inclined block 14 is away from the inner wall of the outer shell 1, the inclined ring 15 drives the lifting ring 12 to rise in the upper grinding disc 4 and descend in the lower grinding disc 11.

[0025] Further, the relative center of the upper grinding disc 4 and the lower grinding disc 11 is embedded with a battery box 17, the box body extends outward and is fixed to the inner side of the rotating ring 3, the battery box 17 is used to control the extension and contraction of the electric push rod 16, the outer wall of the battery box 17 can be made of relatively hard and wear-resistant materials, the battery box 17 is used to supply power to the electric push rod 16, and enough power is provided to support the rotation of the electric push rod 16.

[0026] Further, the inner bottom surface of the shell 1 is rotatably connected with a center column 10 passing through the centers of the upper grinding disc 4 and the lower grinding disc 11, and the center column 10 is rigidly connected with the outer surface of the lower grinding disc 11. The center column 10 is driven to rotate by installing a motor on the outer bottom surface of the shell 1. When the motor drives the center column 10 to rotate clockwise, the lower grinding disc 11 connected with the center column 10 is driven to rotate clockwise. The top center of the upper grinding disc 4 is rotatably connected with an outer tooth ring 9 inserted on the center column 10. The top end of the outer tooth ring 9 is rotatably connected with a connecting frame 6 sleeved on the center column 10 and inserted with the inner wall of the shell 1. The outer tooth ring 9 can slide on the surface of the center column 10, and the connecting frame 6 rotatably connected with the outer tooth ring 9 can move with the outer tooth ring 9 when inserted with the inner wall of the shell 1. Because the connecting frame 6 is inserted with the inner wall of the shell 1 and rotatably connected with the outer tooth ring 9, the connecting frame 6 will not rotate when the outer tooth ring 9 rotates. The connecting frame 6 is rotatably connected with a straight gear 8 engaged with the outer tooth ring 9. The top edge of the upper grinding disc 4 is fixedly connected with an inner tooth ring 7 having the same center as the outer tooth ring 9 and engaged with the straight gear 8. When the center column 10 rotates clockwise, the outer tooth ring 9 sleeved on the center column 10 rotates clockwise, and the straight gear 8 engaged with the outer tooth ring 9 rotates counterclockwise on the connecting frame 6. The straight gear 8 is engaged with the inner tooth surface of the inner tooth ring 7, so the inner tooth ring 7 rotates counterclockwise, and the upper grinding disc 4 rotates counterclockwise, that is, the upper grinding disc 4 and the lower grinding disc 11 rotate in opposite directions. A plurality of hydraulic rods 2 are installed on the top edge of the outer side of the shell 1. The plurality of hydraulic rods 2 are arranged in a ring around the center column 10, and the extension end of the plurality of hydraulic rods 2 is fixedly installed with a pressing ring 5 rotatably connected with the top edge of the upper grinding disc 4. The contraction of the hydraulic rod 2 drives the upper grinding disc 4 in a rotating state to descend. The cross section of the center column 10 is rectangular, and the surface of the center column 10 is slidably connected with the battery box 17, so that the center column 10 can smoothly drive the battery box 17 and the rotating ring 3 to rotate. The center column 10 is matched with the inner side gap of the upper grinding disc 4 and the lower grinding disc 11, so that the center column 10 will not drive the upper grinding disc 4 to rotate in the same direction when rotating.

[0027] The working principle is that according to the size of the raw material entering between the upper grinding disc 4 and the lower grinding disc 11, the inclined block 14 at the extension end of the electric push rod 16 is moved by extension control, the contact of the inclined edge of the inclined block 14 and the inner inclined surface of the inclined ring 15, when the inclined block 14 is close to the inner wall of the shell 1, the inclined ring 15 drives the lifting ring 12 to descend in the upper grinding disc 4 and ascend in the lower grinding disc 11, when the inclined block 14 is away from the inner wall of the shell 1, the inclined ring 15 drives the lifting ring 12 to ascend in the upper grinding disc 4 and descend in the lower grinding disc 11, the position of the lifting ring 12 in the upper grinding disc 4 and the lower grinding disc 11 is controlled to control the length of the surface engaging tooth 13 extending out of the upper grinding disc 4 and the lower grinding disc 11, then the reverse rotation of the upper grinding disc 4 and the lower grinding disc 11 is realized by the rotation of the center column 10, and the raw material is clamped and rotated by the engaging tooth 13, and the raw material is ground by the friction between the raw materials.

[0028] The wiring diagram of the battery box 17, the hydraulic rod 2, the motor and the electric push rod 16 in the utility model belongs to the common knowledge in the field, and the working principle is a known technology, and the model is selected according to actual use, so the control mode and wiring arrangement of the battery box 17, the hydraulic rod 2, the motor and the electric push rod 16 are not explained in detail.

[0029] The above is only the preferred embodiment of the utility model, and does not limit other forms of the utility model, and any skilled person in the art can change or modify the above disclosed technical content into equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made according to the technical essence of the utility model to the above embodiments still belong to the protection scope of the utility model technical scheme.
