[0002] Graphite, also known as black lead, is an allotrope of carbon with a relative density of 2.256 g / cm³. Graphite is opaque and has an oily feel. Its color ranges from iron black to steel gray, and it can exist in crystalline, flake, scaly, striped, or layered forms. Graphite has low hardness, is chemically stable, and does not readily react with acids or alkalis. It is also resistant to high temperatures, corrosion, thermal shock, and radiation. Furthermore, it possesses high strength, good toughness, self-lubricating properties, and electrical and thermal conductivity.

[0003] The prior art patent application with publication number CN218486185U uses a filter screen to filter out graphite particles that do not meet the requirements. A cylinder drives a scraper to clean the larger graphite particles on the surface of the filter screen through the discharge port onto a conveying device. The larger graphite particles can be put back into the crushing box for further crushing through the transmission of the conveying device, avoiding manual repeated feeding and improving the production efficiency of the device.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] First Embodiment

[0025] Please refer to the following: Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a graphite pulverizer for lithium battery negative electrode materials provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the switching device. A graphite pulverizer for lithium battery negative electrode materials includes: a pulverizing device 1, a screening device 2, and a switching device 3;

[0026] The screening device 2 is fixedly installed inside the crushing device 1;

[0027] The switching device 3 includes a rotating disk 31, four pressure sensors 32, a rotating frame 33, four discharge ports 34, a discharge pipe 35, and a servo motor 36. The rotating disk 31 is rotatably connected to the inside of the crushing device 1. The four pressure sensors 32 are all fixedly installed inside the rotating disk 31. The rotating frame 33 is fixedly installed on the top of the rotating disk 31. The four discharge ports 34 are all opened inside the rotating frame 33. The discharge pipe 35 is located on the top of the rotating frame 33. The servo motor 36 is located on the top of the rotating disk 31.

[0028] One end of the discharge port 34 is fixedly installed on the top of the crushing device 1 and located below the screening device 2, and is used to transport the screened graphite particles into the interior of multiple collection boxes on the top of the rotating disk 31 for storage.

[0029] The rotating frame 33 is a ring, and multiple connecting rods are fixedly connected to the bottom. The other ends of the multiple connecting rods are fixedly connected to the top of the rotating disk 31. The interior of the rotating frame 33 has four discharge ports 34. When one of the four discharge ports 34 overlaps with one end of the discharge pipe 35, the graphite particles inside the discharge pipe 35 are discharged into the interior of the collection box. When one end of the discharge pipe 35 in one of the multiple discharge ports 34 is staggered, the rotating frame 33 seals one end of the discharge pipe 35.

[0030] The servo motor 36 is fixedly installed inside the crushing device 1, and its output end is connected to the top of the rotating disk 31 via a coupling.

[0031] The screening device 2 includes a screening frame 21, a vibration motor 22, and four reset pieces 23. The screening frame 21 is slidably connected to the inside of the crushing device 1. The vibration motor 22 is fixedly installed on the top of the screening frame 21. One end of each of the four reset pieces 23 is fixedly installed at the four corners of the bottom of the screening frame 21.

[0032] A screening screen is fixedly installed inside the screening frame 21 for screening the graphite particles crushed by the crushing device 1. At the same time, one end of the screening frame 21 is tilted downward, so that the unqualified graphite particles are conveyed to the inside of the conveying device on one side of the crushing device 1 and then conveyed into the feed inlet of the crushing device 1.

[0033] The conveying device can be a conveying auger or a material conveying pump.

[0034] One end of each of the four reset components 23 is fixedly installed on both sides of the inner wall of the crushing device 1.

[0035] The reset component 23 is a spring telescopic rod or spring, used to reset the screening frame 21 and cooperate with the vibration motor 22 to screen the graphite particles that have entered the screening frame 21.

[0036] A protective frame 5 is fixedly installed on the top of the crushing device 1, and a sealing plate 6 is fixedly connected to the top of the protective frame 5.

[0037] The protective frame 5, together with the sealing plate 6, is used to protect the top of the crushing device 1 and reduce the amount of graphite powder that is scattered when graphite is added into the crushing device 1.

[0038] The working principle of the graphite pulverizer for lithium battery negative electrode materials provided by this utility model is as follows:

[0039] In use, when the graphite crushed inside the crushing device 1 enters the screening frame 21, the vibrating motor 22 is started to screen the graphite particles inside the screening frame 21. The graphite particles that pass through the screening frame 21 will be discharged into the collection box placed on the rotating disk 31 through the discharge pipe 35 and the discharge port 34 for storage.

[0040] When the pressure sensor 32 detects that a collection box is full of graphite particles, the servo motor 36 starts and drives the rotating disk 31 to rotate to one side, thereby switching the multiple collection boxes placed on the rotating disk 31. At the same time, as the rotating disk 31 rotates to one side, it drives the rotating frame 33 to rotate to one side, so that the discharge port 34 is misaligned with one end of the discharge pipe 35. The rotating frame 33 then seals one end of the discharge pipe 35. When the next one moves below the discharge pipe 35, the servo motor 36 automatically shuts off, and one of the multiple discharge ports 34 inside the rotating frame 33 aligns with one end of the discharge pipe 35, thereby allowing the discharge pipe 35 to discharge the material.

[0041] Compared with related technologies, the graphite pulverizer for lithium battery negative electrode materials provided by this utility model has the following beneficial effects:

[0042] This utility model provides a graphite pulverizer for lithium battery negative electrode materials. The sieved graphite particles are discharged into the collection box placed on the rotating disk 31 through the discharge pipe 35 and the discharge port 34. At the same time, with the help of pressure sensor 32, servo motor 36 and rotating frame 33, the collection box is automatically switched after it is full of graphite particles. Therefore, it is not necessary to stop the graphite pulverization and switch the collection box, which increases the working efficiency.

[0046] The dustproof device 4 is a vacuum cleaner, which is fixedly installed on the top of the sealing plate 6, and the suction port is fixedly installed on the top of the feed port of the protective frame 5. It is used to suck up the graphite powder that is scattered when graphite is added inside the crushing device 1.

[0047] The dustproof device 4 includes a rotating rod 41, a rotating plate 42, and a plurality of sealing gaskets 43. The rotating rod 41 is rotatably connected to the inside of the sealing plate 6. The top of the rotating plate 42 is fixedly connected to the surface of the rotating rod 41. One end of each of the plurality of sealing gaskets 43 is fixedly connected to the bottom of the rotating plate 42.

[0048] Multiple sealing gaskets 43 are used to seal the feed inlet of the protective frame 5, thereby reducing the amount of graphite powder that is scattered when graphite is added into the crushing device 1.

[0049] The working principle of the graphite pulverizer for lithium battery negative electrode materials provided by this utility model is as follows:

[0050] When graphite is added into the crushing device 1 during use, the sealing gasket 43 will bend to one side, allowing the graphite to enter the crushing device 1.

[0051] When it is necessary to lift the sealing gasket 43, the multiple sealing gaskets 43 are flipped to one side, thereby causing the rotating plate 42 connected to the rotating rod 41 to rotate to one side, so that the multiple sealing gaskets 43 are opened.

[0052] Compared with related technologies, the graphite pulverizer for lithium battery negative electrode materials provided by this utility model has the following beneficial effects:

[0053] This utility model provides a graphite pulverizer for lithium battery negative electrode materials. The protective frame 5 is protected by a dustproof device 4, thereby reducing the amount of graphite powder that is scattered when graphite is added into the pulverizer 1.
