Technical Field

[0001] The utility model relates to the technical field of magnesium powder production, in particular to a non-flaky magnesium powder production device. Background Technique

[0002] Non-flaky magnesium powder is the powder state of elemental magnesium, with an appearance of silver-white metallic luster powder, which is an active metal and a flammable item when wet. When burning, it produces a strong white light and releases high heat. Reacting with water or moisture releases hydrogen, with a large amount of heat released, causing combustion or explosion. Reacting violently with chlorine, bromine, iodine, sulfur, phosphorus, arsenic and oxidants, there is a risk of combustion and explosion. Magnesium powder needs to be ground during the production process;

[0003] Existing magnesium powder production grinding devices usually install grinding structures on the inner wall and the central position of the inner cavity of the device, and carry out grinding processing under the cooperation of the rotation of a set of grinding structures and another set of grinding structures. Such a structure has a low grinding accuracy for magnesium powder, and at the same time, it is easy to explode during the grinding process of magnesium powder, posing a safety hazard. Content of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solution: A non-flaky magnesium powder production device, including a grinding box, the upper and lower sides inside the grinding box are respectively fixedly connected with an upper mounting block and a lower mounting block, the inner parts of the upper mounting block and the lower mounting block are respectively provided with a first grinding cavity and a second grinding cavity, the top end inside the grinding box is rotatably connected with a rotating shaft, the rotating shaft sequentially penetrates through the first grinding cavity and the second grinding cavity, the outer wall of the rotating shaft is respectively fixedly connected with a first grinding block and a second grinding block at the upper and lower sides, the first grinding block and the second grinding block are respectively located inside the first grinding cavity and the second grinding cavity, and the outer walls of the first grinding cavity and the first grinding block are respectively fixedly connected with a plurality of uniformly distributed first grinding teeth, and the outer walls of the second grinding cavity and the second grinding block are respectively fixedly connected with a plurality of uniformly distributed second grinding teeth.

[0006] To facilitate grinding of magnesium powder, as a preferred non-flaky magnesium powder production device of the utility model, the first grinding cavity, the second grinding cavity, the first grinding block and the second grinding block are all conical structures.

[0007] To make the magnesium powder more refined, as a preferred non-flaky magnesium powder production device of the utility model, the minimum distance between the first grinding cavity and the first grinding block is greater than the minimum distance between the second grinding cavity and the second grinding block.

[0008] For the convenience of guiding materials, as an optimization of the non-flaky magnesium powder production device of the present utility model, the upper end faces of the upper mounting block and the lower mounting block are respectively fixedly connected with a first material guiding cavity and a second material guiding cavity in a conical structure.

[0009] For the convenience of feeding and discharging materials, as an optimization of the non-flaky magnesium powder production device of the present utility model, a feeding port is fixedly connected to the left side of the upper end face of the grinding box, a collection drawer is movably connected to the bottom end inside the grinding box, and a plurality of balls are rotatably connected to the bottom of the collection drawer.

[0010] For the convenience of introducing inert gas, as an optimization of the non-flaky magnesium powder production device of the present utility model, an air inlet pipe is fixedly connected to the right side of the top of the grinding box, a valve is arranged on the outer wall of the air inlet pipe, a motor is installed at the center of the top of the grinding box, and the output end of the motor is fixedly connected with a rotating shaft.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] During the use process, the magnesium powder to be ground is put into the grinding box through the feeding port and distributed inside the first material guiding cavity. Then, inert gas is introduced into the grinding box through the air inlet pipe, and the air inside the grinding box is discharged through the feeding port. Subsequently, the feeding port and the air inlet pipe are closed to seal the inside of the grinding box, avoiding the occurrence of phenomena such as explosion after the magnesium powder comes into contact with the outside air and improving safety.

[0014] Start the motor to drive the rotating shaft to rotate. The rotating shaft simultaneously drives the first grinding block and the second grinding block to rotate. The magnesium powder first passes between the first grinding block and the first grinding cavity and is finely ground through the first grinding teeth. The ground magnesium powder drops downward into the second material guiding cavity and further enters between the second grinding cavity and the second grinding block. The minimum distance between the first grinding cavity and the first grinding block is greater than the minimum distance between the second grinding cavity and the second grinding block. At the same time, the number of teeth and the size of the second grinding teeth are both smaller than those of the first grinding teeth, thereby further grinding the magnesium powder, making the grinding more refined and the magnesium powder more delicate. By setting two grinding mechanisms, the magnesium powder is ground step by step, first being roughly ground and then finely ground, improving the grinding accuracy and efficiency.

Subsequently, the feeding port 13 and the air inlet pipe 16 are closed to seal the inside of the grinding box 1, avoiding the occurrence of phenomena such as explosion after the magnesium powder comes into contact with the outside air and improving safety;

[0021] The starting motor 20 drives the rotating shaft 6 to rotate. The rotating shaft 6 simultaneously drives the first grinding block 7 and the second grinding block 8 to rotate. The magnesium powder first passes between the first grinding block 7 and the first grinding chamber 4 and is finely ground by the first grinding teeth 9.

The collecting drawer 14 is used for collecting the ground magnesium powder and can be pulled outwards, making it convenient to take the material. A sealing gasket is provided between the collecting drawer 14 and the grinding box 1 to ensure the internal sealing of the grinding box 1 after the collecting drawer 14 is closed. The balls 15 reduce the friction at the bottom of the collecting drawer 14 and make it easier to pull out.

[0034] Working principle: During the use, the magnesium powder to be ground is put into the grinding box 1 through the feed inlet 13 and distributed inside the first material guiding cavity 11. Then, inert gas is introduced into the grinding box 1 through the air inlet pipe 16, and the air in the grinding box is discharged through the feed inlet 13.
