DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to specific embodiments. Figures 1 to 3 As shown:

[0018] Example 1: A nano-dispersed alumina grinding equipment includes a frame 1, an inner liner 7 is arranged in the frame 1, and horizontal axes 2 are arranged on both sides of the inner liner 7. The two horizontal axes 2 extend coaxially and are both rotatably connected to the frame 1. The frame 1 is provided with a rotating mechanism connected to the horizontal axis 2. The rotating mechanism controls the rotation of the horizontal axis 2, thereby controlling the rotation of the inner liner 7. A valve 17 is provided at the end of the inner liner 7, and the valve 17 is used to control the opening and closing of the inner liner 7.

[0019] The inner bottom end of the inner liner 7 is conical, and a guide tube 8 is provided inside the inner liner 7. The guide tube 8 is fixedly connected to the inner liner 7 by a fixed beam. A drive shaft 9 is vertically slidably provided in the guide tube 8. A cavity 10 is provided in the guide tube 8. A limit ring 11 is provided on the side wall of the drive shaft 9. The limit ring 11 is used to limit the upper and lower limit positions of the drive shaft 9. The drive shaft 9 is connected to a grinding cone 16.

[0020] A first drive motor 13 is provided on the side wall of the inner liner 7. The first drive motor 13 is provided with a retractable transmission shaft 14. The retractable transmission shaft 14 is connected to the drive shaft 9 by a universal joint. The first drive motor 13 drives the drive shaft 9 and the grinding cone 16 to rotate through the retractable transmission shaft 14 and the universal joint. The nano-alumina is ground by the grinding cone 16 and the inner wall of the inner liner 7. When unloading after grinding, the inner liner 7 is rotated 180 degrees so that the valve 17 faces downward. Under the action of gravity, the gap between the grinding cone 16 and the inner wall of the inner liner 7 increases, which facilitates the falling of the nano-alumina powder in the inner liner 7. The valve 17 is opened and the alumina powder falls from the valve 17.

[0021] Example 2: A nano-dispersed alumina grinding equipment includes a frame 1, an inner liner 7 is provided in the frame 1, and horizontal axes 2 are provided on both sides of the inner liner 7. The two horizontal axes 2 extend coaxially and are both rotatably connected to the frame 1. The frame 1 includes an outer shell, and a feed funnel 3 and a discharge funnel 4 are respectively provided at the upper and lower ends of the outer shell. The feed funnel 3 is slidably connected to the outer shell, and a first telescopic rod 5 is vertically provided on the outer shell. The first telescopic rod 5 is fixedly connected to the feed funnel 3, and the frame 1 is provided with a rotating mechanism connected to the horizontal axis 2.

[0022] The rotating mechanism includes a driven bevel gear 61, a driving bevel gear 62 and a second drive motor 63. The second drive motor 63 is arranged on the frame 1. The driving bevel gear 62 is connected to the second drive motor 63. The driven bevel gear 61 is fixedly set on one of the horizontal shafts 2. The driving bevel gear 62 is engaged with the driven bevel gear 61. The rotating mechanism controls the rotation of the horizontal shaft 2, thereby controlling the rotation of the inner liner 7. A valve 17 is provided at the end of the inner liner 7. The valve 17 is used to control the opening and closing of the inner liner 7.

[0023] The inner bottom end of the inner liner 7 is conical, and a guide tube 8 is arranged inside the inner liner 7. The guide tube 8 is fixedly connected to the inner liner 7 by a fixed beam. A drive shaft 9 is vertically slidably arranged in the guide tube 8. A cavity 10 is opened in the guide tube 8. A limit ring 11 is provided on the side wall of the drive shaft 9. The limit ring 11 is used to limit the upper and lower limit positions of the drive shaft 9. A plurality of balls 12 are evenly arranged on the lower end of the limit ring 11. The balls 12 reduce the friction between the limit ring 11 and the guide tube 8. The drive shaft 9 is connected to a grinding cone 16.

[0024] A first drive motor 13 is provided on the side wall of the inner liner 7, and the first drive motor 13 is provided with a telescopic transmission shaft 14. The telescopic transmission shaft 14 is connected to the drive shaft 9 by a universal joint. A second telescopic rod 15 is vertically provided on the frame 1, and the second telescopic rod 15 corresponds to one of the horizontal axes 2 up and down. A limiting hole corresponding to the second telescopic rod 15 is provided on the horizontal axis 2. The second telescopic rod 15 is extended and inserted into the limiting hole to fix the position of the inner liner 7.

[0025] The specific working process is as follows: control the rotating mechanism to drive the inner liner 7 to rotate to a state where the vertical valve 17 is facing upward, use the second telescopic rod 15 to extend and insert into the limit hole to limit the inner liner 7, open the valve 17, control the first telescopic rod 5 to insert the feeding funnel 3 into the valve 17, and put the nano-alumina powder to be ground into the inner liner 7, then control the feeding funnel 3 to be pulled out from the valve 17, close the valve 17, and the first drive motor 13 drives the drive shaft 9 and the grinding cone 16 to rotate through the telescopic transmission shaft 14 and the universal joint, and uses the grinding cone 16 and the inner wall of the inner liner 7 to grind the nano-alumina. When unloading after grinding, rotate the inner liner 7180 degrees to make the valve 17 face downward. Under the action of gravity, the gap between the grinding cone 16 and the inner wall of the inner liner 7 increases, which facilitates the falling of the nano-alumina powder in the inner liner 7, and opens the valve 17. The alumina powder falls from the valve 17 into the outer shell discharged by the discharge funnel 4.

[0026] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
