Description

Technical Field

[0001] The present invention relates to the technical field of graphite processing, and particularly relates to a crushing and suction device for a graphitization crucible. Background Art

[0002] In the graphitization process stage of the anode material (graphite) of a new energy lithium-ion battery, it is necessary to load the graphitized raw material (powder form) into a crucible (with a diameter of 600 mm and a height of 1100 mm), heat it at a high temperature in a graphitization furnace, then cool it, and finally transfer the graphite out of the crucible. Since the graphite powder is preferably transferred by vacuum negative pressure suction during the transfer process. At present, it is mostly manual to first manually crush the graphite in the crucible, and then hold a negative pressure suction tool to suck the material. This method is prone to dust generation, making the on-site environment poor. The graphite dust is extremely fine and not easy to protect, causing great harm to the human body. At the same time, manual suction makes the efficiency low. Summary of the Invention

A number of tool plates 6 are arranged on the tool disc 5. A number of cutting tools 7 for crushing graphite are arranged on the tool plates 6. The cutting tools 7 are inclined and used for pushing the crushed graphite towards the rotation center of the tool disc 5. A limiting plate 8 is fixedly arranged at the end of the connecting pipe 2. A number of feed holes 11 are arranged on the limiting plate 8. A rotary cutter 9 matching with the feed holes 11 is fixedly arranged on the tool disc 5. The driving component is arranged on the connecting plate 1 and used for driving the rotating sleeve 3 to rotate. A scraping blade 19 is arranged on the tool plate 6, and the scraping blade 19 is matched with the inner wall of the crucible 20. At least two tool plates 6 are evenly arranged on the tool disc 5. The cross section of the rotary cutter 9 is S-shaped, and both ends of the rotary cutter 9 are fixedly connected with the tool disc 5. The connecting pipe 2 and the rotating sleeve 3 are connected by a bearing. The main suction pipe 10 is connected with a robot 22. In this technical solution, in the prior art, the robot 22 grabs the main suction pipe 10. The main suction pipe 10 is communicated with the connecting pipe 2. The graphite material enters the connecting pipe 2 through the feed holes 11 on the limiting plate 8, and then the graphite material in the crucible 20 is sucked away through the main suction pipe 10. The end of the main suction pipe 10 is connected with a negative pressure device in the prior art. The rotating sleeve 3 is fixed on the connecting pipe 2 by a bearing. The driving motor 15 drives the rotating sleeve 3 to rotate through a gear set. The rotating sleeve 3 drives the rotating disc 4 to rotate. The rotating disc 4 drives the tool disc 5 to rotate through the floating connection component, so that the tool plates 6, the cutting tools 7 and the rotary cutter 9 on the tool disc 5 rotate. Among them, the connecting plate 1, the rotating disc 4 and the tool disc 5 are all circular discs, the connecting pipe 2 and the rotating sleeve 3 are all circular pipes, and the connecting plate 1, the rotating disc 4, the tool disc 5, the connecting pipe 2 and the rotating sleeve 3 are all coaxially arranged. Four tool plates 6 are evenly arranged on the tool disc 5. Each tool plate 6 is arranged along the radius direction of the tool disc 5. A plurality of cutting tools 7 are inclined on each tool disc 5. The specific inclination direction of the cutting tool 7 is that the cutting edge of the cutting tool 7 is far away from the axis of the tool disc 5, and the back of the cutting tool 7 is close to the axis of the tool disc 5. The rotary cutter 9 is matched with the limiting plate 8. When graphite material is stuck in the feed holes 11 on the limiting plate 8, the rotary cutter 9 rotates under the action of the tool disc 5, which can not only cut the graphite material in the feed holes 11, but also squeeze the graphite material inward. The rotary cutter 9 is S-shaped, which helps the graphite material to move towards the feed holes 11.A plurality of feed holes 11 are provided on the limit plate 8. The advantage of this setting is to prevent large pieces of graphite material from blocking the connecting pipe 2 and the main suction pipe 10. A scraping blade 19 is further provided on the tool plate 6, and the scraping blade 19 can effectively scrape the graphite material on the inner wall of the crucible 20. The entire device can efficiently suck the graphite material in the crucible 20. The outer wall of the connecting disc 1 cooperates with the inner wall of the crucible 20 to effectively prevent dust leakage during the crushing process.

[0030] In some embodiments, the floating connection assembly includes a limit rod 12 and a return spring 13. One end of the limit rod 12 is fixedly connected to the rotating disc 4, the tool disc 5 is slidably arranged on the other end of the limit rod 12, the return spring 13 in a compressed state is sleeved on the limit rod 12, one end of the return spring 13 contacts the rotating disc 4, the other end of the return spring 13 contacts the tool disc 5, and a sliding hole 14 cooperating with the limit rod 12 is provided on the tool disc 5. In this technical solution, four groups of floating connection assemblies are evenly arranged between the rotating disc 4 and the tool disc 5. One end of the limit rod 12 is fixedly connected to the rotating disc 4, and a convex ring is provided at the other end. The return spring 13 is sleeved on the limit rod 12, and one end thereof abuts against the tool disc 5, and the other end abuts against the tool disc 5, so that floating is achieved between the rotating disc 4 and the tool disc 5. It can prevent the cutting tool 7 from directly colliding with the bottom of the crucible 20 during the process of crushing graphite and causing equipment damage.

[0031] In some embodiments, the driving assembly includes a driving motor 15, a driving gear 16 and a driven gear 17. The driving motor 15 is fixedly arranged on the connecting disc 1, the driving gear 16 is fixedly arranged on the output shaft of the driving motor 15, and the driven gear 17 is fixedly arranged on the rotating sleeve 3 and meshes with the driving gear 16. In this technical solution, the driving motor 15 is a motor in the prior art. The driving motor 15 drives the driving gear 16 to rotate, the driving gear 16 drives the driven gear 17 to rotate, and the driven gear 17 drives the rotating sleeve 3 to rotate, so as to achieve the purpose of crushing graphite.

[0032] In some embodiments, a protective sleeve 18 is coaxially and fixedly arranged on the connecting disc 1, and the inner wall of the protective sleeve 18 cooperates with the outer wall of the tool disc 5. In this technical solution, the cross section of the protective sleeve 18 is circular, its upper end is hermetically connected to the connecting disc 1, and there is a clearance fit between its lower inner wall and the outer wall of the tool disc 5, so as to prevent the graphite material from affecting the driving assembly and prevent the failure of the function of the driving assembly.

The graphite material at the side wall of the crucible 20 can be sucked through the auxiliary suction pipes 21. The upper ends of the auxiliary suction pipes 21 are communicated with the main suction pipe 10 through pipelines, so that only one negative pressure device is needed to efficiently suck the graphite material.
