Description

Technical Field

[0001] The utility model relates to the technical field of graphite processing devices, in particular to a dust filtering device for graphitization production. Background Art

[0002] Graphite is an allotrope of carbon. It is a gray-black, opaque solid with stable chemical properties, corrosion resistance, and is not prone to react with acids and alkalis. Natural graphite comes from graphite deposits. It can also be made into artificial graphite from petroleum coke, asphalt coke, etc. through a series of processing steps.

[0003] Although the existing graphite processing device can process graphite during use, it is not equipped with a mechanism to filter graphite dust. Therefore, during the operation, graphite particles are easily caused to float in the air, which not only reduces the user's utilization rate of graphite materials, but also the graphite dust in the air will be absorbed by the human body, thereby causing adverse effects on human body functions. For this reason, we propose a dust filtering device for graphitization production. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a dust filtering device for graphitization production, which has the advantages of effectively isolating graphite dust, ensuring graphite output, and facilitating users to recycle and clean graphite dust, thereby solving the problems raised by the above-mentioned background technology.

The output shaft of the motor 22 is fixedly assembled with a cam 23. The outer wall of the cam 23 is in contact with the screen 13. The outer walls of the screen 13 on both sides are fixedly assembled with limit blocks 3. The inner walls of both sides of the box body 1 are provided with limit grooves 24. The inner walls of the limit grooves 24 are fixedly assembled with cross bars 14. The outer wall of the cross bar 14 is sleeved with a return spring 25. The end of the box body 1 close to the motor 22 is fixedly assembled with motor 2 17, and the output shaft of motor 2 17 is fixedly sleeved with screw rod 2 18. The outer wall of screw rod 2 18 is threadedly connected with a scraper 19. The inner wall of the box body 1 close to one end of motor 2 17 is fixedly assembled with a material guide plate 20, and the top of the inner wall of the box body 1 is fixedly assembled with a limit plate 21.

[0022] In the above structure, through the set box body 1, hopper 2, limit block 3, motor 7, shield plate 8, connecting pipe 9, sleeve 10, recovery box 11, and dust collection net 12 structure, during the operation of the device, the user can move the shield plate 8 through the operation of motor 7, so that the shield plate 8 covers the hopper 2, and prevents the flying dust generated during the grinding process from falling to the outside of the box body 1. It can not only recycle the graphite dust, but also reduce the impact of the graphite dust on the operators. After grinding, the operation of the motor 22 is coordinated to make the screen 13 shake, so as to ensure the output quality of the graphite dust, and facilitate the user to recycle the larger volume of graphite for secondary grinding, thereby ensuring the processing effect of the device on the graphite.

[0023] In a preferred embodiment: the shape of the mask plate 8 is adapted to the shape of the top of the hopper 2, and when the position of the hopper 2 coincides with the position of the mask plate 8, the hopper 2 is isolated from the outside world, and the interior of the recovery box 11 is connected to the interior of the hopper 2 through the connecting pipe 9, the sleeve 10 and the exhaust fan 26.

[0024] In the above structure, by setting the shield plate 8 and the connecting pipe 9 structure, the user can shield the hopper 2 by moving the shield plate 8, and it is also convenient for the user to add graphite to the inside of the hopper 2 for grinding operations, thereby ensuring the normal use of the device, and the movement of the shield plate 8 can be automatically adjusted, thereby improving the automation of the device and the user's operating efficiency.

[0025] In a preferred embodiment, the outer wall of the limiting plate 21 is rotatably connected to the end of the second screw rod 18 , and the bottom of the scraper 19 is slidably connected to the top of the guide plate 20 .

[0026] In the above structure, through the set limit plate 21 and scraper 19 structure, when the grinding rod 4 grinds the graphite, part of the graphite will fall on the guide plate 20. At this time, the user can rotate the screw 2 18 through the operation of the motor 2 17, so that the scraper 19 can scrape the top of the guide plate 20 to avoid the accumulation of graphite dust on the guide plate 20, thereby ensuring that the graphite dust can be sent to the outside of the box 1 in time, thereby improving the user's collection efficiency of graphite dust.

[0027] In a preferred embodiment, the outer wall of the limiting block 3 conflicts with the outer wall of the return spring 25 , and the outer wall of the limiting block 3 is slidably connected to the inner wall of the limiting groove 24 .

[0028] In the above structure, the limit block 3 and the limit groove 24 structure are set, so that the screen 13 will compress the reset spring 25 during the movement, so that the cam 23 uses the elasticity of the reset spring 25 to automatically reset the screen 13 after rotating one circle, thereby achieving the effect of automatic screening, and then ensuring the filtering effect of the device on graphite dust.

[0029] In a preferred embodiment, square grooves are formed on both outer walls of the box body 1 , and the inner walls of the square grooves are slidably connected to the outer walls of the screen 13 .

[0030] In the above structure, by setting the square groove structure, when the cam 23 rotates, due to its different diameters, the screen 13 will be pushed and moved, thereby achieving the effect of automatic screening, thereby ensuring the normal operation of the device and improving the precision matching of the internal components of the device.

[0031] In a preferred embodiment, a sealed door is provided on the front of the box body 1, and a handle is fixedly mounted on the outer wall of the sealed door.

[0032] In the above structure, through the provided sealing door structure, after the user uses the device to screen the ground graphite dust, the user can remove the graphite blocks accumulated on the screen 13 by opening the sealing door, thereby facilitating the user to put the graphite blocks into the device for secondary grinding, and further facilitating the user to clean the graphite blocks.

[0033] Working principle: First, after the user assembles the device, he directly puts the graphite into the hopper 2, and then uses the operation of the motor 7 to make the shield plate 8 shield the hopper 2. During the rotation of the grinding rod 4, the flying graphite dust will not leak to the outside of the device under the barrier of the shield plate 8. At the same time, the operation of the exhaust fan 26 is used to absorb the graphite dust floating in the air and discharge it together with the air into the recovery box 11. The dust collection net 12 is used to absorb the graphite particles, and then the clean air is discharged through the exhaust pump. 16 is discharged, and part of the graphite dust falls on the guide plate 20 due to gravity. At this time, the user can use the operation of the motor 2 17 to move the scraper 19 to scrape off the graphite dust, thereby ensuring that the graphite dust falls on the screen 13. The operation of the motor 22 is used to rotate the cam 23 to cooperate with the screen 13 to screen the graphite dust. The user can pick up the fallen graphite dust, and the remaining graphite blocks will stagnate on the screen 13. Finally, the user can open the sealed door to take out the graphite blocks and repeat the same steps for secondary grinding.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
