Description

Technical Field

[0001] This utility model relates to the field of graphite powder processing, and in particular to a processing device for ultrafine high-purity conductive graphite powder. Background Technology

[0002] With its core advantages of ultrafine particle size, high carbon purity, excellent conductivity and chemical stability, ultrafine high-purity conductive graphite powder has become a key basic material in the high-end manufacturing field. Its core applications cover four major fields: electronic information, new energy, high-end lubrication and composite materials, and it plays an irreplaceable functional role in each field.

[0003] In the field of processing ultrafine high-purity conductive graphite powder, existing grinding devices mostly adopt a single-direction cylindrical grinding structure, which can only generate a single grinding force through the revolution or rotation of the grinding media. This results in low grinding efficiency and poor material grinding uniformity, making it difficult to meet the processing requirements of ultrafine and high-purity graphite powder. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an ultrafine high-purity conductive graphite powder processing device, which aims to improve the problem that traditional grinding devices can only generate a single grinding force, resulting in low grinding efficiency and poor material grinding uniformity.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrafine high-purity conductive graphite powder processing device, comprising a machine body, an outer cylinder rotatably connected to the inner wall of the machine body, a motor fixedly connected to the inner wall of the machine body, a first impeller fixedly connected to the output end of the motor, a transmission gear rod rotatably connected to the inner wall of the machine body, an inner core rotatably connected to the inner wall of the outer cylinder, a second impeller fixedly connected to one end of the inner core, grinding balls slidably connected to the outer wall of the inner core, a feed inlet provided at the top of the outer cylinder, and a secondary sieving assembly provided at the bottom of the outer cylinder.

[0006] According to the above technical solution, the first impeller is driven by a motor to rotate, and the first impeller meshes with the second impeller to rotate, thereby causing the inner core to rotate. The rotation of the first impeller drives the transmission gear rod to rotate, and the rotation of the transmission gear rod causes the outer cylinder to rotate, thus achieving the effect of the outer cylinder rotating clockwise and the inner core rotating counterclockwise, thereby achieving the effect of rotation in different directions. Under the action of the outer cylinder, the grinding balls revolve with the outer cylinder, and under the action of the inner core, the grinding balls achieve self-rotation, thereby achieving dual grinding forces of shearing and crushing, and improving grinding efficiency.

[0007] Preferably, the secondary screening assembly includes a collection chamber, the inner wall of which is slidably connected to the outer wall of the outer cylinder, a transmission rod is fixedly connected to the bottom end of the inner core, a scraper is fixedly connected to the outer wall of the transmission rod, a rotating screen is fixedly connected to the outer wall of the transmission rod, a screening chamber is provided on the outer wall of the collection chamber, and a vibrating screen is fixedly connected to the inner wall of the collection chamber.

[0008] Preferably, the inner core has a spiral groove on its surface, the outer cylinder has a spiral protrusion on its inner wall, and the grinding ball is slidably connected to the surface of the spiral protrusion.

[0009] Preferably, the two ends of the transmission gear rod are rotatably connected to the inner wall of the machine body, and the surface of the transmission gear rod is provided with multiple gears. One gear of the transmission gear rod is meshed with the outer wall of the first impeller, and the other gear of the transmission gear rod is meshed with the outer wall of the outer cylinder.

[0010] Preferably, the outer wall of the machine body is provided with a feeding port.

[0011] Preferably, one end of the transmission rod is provided with a protrusion, and the upper surface of the vibrating screen is provided with a protrusion.

[0012] Preferably, the outer wall of the collection chamber has an annular opening, and the inner wall of the screening chamber is disposed on the surface of the annular opening.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the first impeller is driven by a motor, and the first impeller drives the second impeller and the inner core to rotate. The first impeller is linked to the transmission gear rod, which drives the outer cylinder to rotate in the opposite direction. Finally, the outer cylinder rotates clockwise and the inner core rotates counterclockwise, so that the grinding balls can complete the revolution and rotation at the same time, forming a dual grinding force of shearing and crushing, which significantly improves the grinding efficiency and realizes all-round grinding.

[0014] 2. In this utility model, the rotation of the inner core drives the rotation of the transmission rod, which causes the scraper fixed on the surface of the transmission rod to scrape the graphite powder that has been ground above into the surface of the rotating screen below. The rotating screen can send the graphite powder that is not ground enough or that is stuck together into clumps into the screening chamber under the action of centrifugal force, where it can be ground a second time. The vibrating screen can perform a second filtration to screen out the graphite powder that does not meet the standards, thus completing the collection. Attached Figure Description

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Reference Figures 1-2 An embodiment of this utility model provides: an ultrafine high-purity conductive graphite powder processing device, including a machine body 1, an outer cylinder 2 rotatably connected to the inner wall of the machine body 1, a motor 5 fixedly connected to the inner wall of the machine body 1, a first impeller 7 fixedly connected to the output end of the motor 5, a transmission gear rod 6 rotatably connected to the inner wall of the machine body 1, an inner core 10 rotatably connected to the inner wall of the outer cylinder 2, a second impeller 8 fixedly connected to one end of the inner core 10, a grinding ball 11 slidably connected to the outer wall of the inner core 10, a feed inlet 9 provided at the top of the outer cylinder 2, and a secondary sieving assembly provided at the bottom of the outer cylinder 2.

[0019] Specifically, motor 5 drives the first impeller 7 to rotate, and the first impeller 7 drives the second impeller 8 to rotate through meshing transmission, which in turn drives the inner core 10 to rotate. The first impeller 7 synchronously drives the transmission gear rod 6 to drive the outer cylinder 2 to rotate in the opposite direction, ultimately realizing the bidirectional rotation of the outer cylinder 2 clockwise and the inner core 10 counterclockwise. This allows the grinding ball 11 to rotate with the outer cylinder 2 while also rotating under the action of the inner core 10, efficiently forming a dual grinding force of shearing and crushing in parallel, greatly enhancing the grinding effect and significantly improving the overall grinding efficiency.

[0020] Reference Figures 3-4The secondary screening assembly includes a collection bin 3, the inner wall of which is slidably connected to the outer wall of the outer cylinder 2, a transmission rod 12 is fixedly connected to the bottom end of the inner core 10, a scraper 13 is fixedly connected to the outer wall of the transmission rod 12, a rotating screen 14 is fixedly connected to the outer wall of the transmission rod 12, a screening bin 4 is provided on the outer wall of the collection bin 3, and a vibrating screen 15 is fixedly connected to the inner wall of the collection bin 3.

[0021] Specifically, the rotation of the inner core 10 synchronously drives the transmission rod 12 to rotate, causing the fixed scraper 13 on the surface of the transmission rod 12 to scrape the ground graphite powder above to the rotating screen 14 below. The rotating screen 14 uses centrifugal force to efficiently separate the graphite powder that is not sufficiently ground or is stuck in clumps and send it into the screening chamber 4 for secondary grinding. Subsequently, the vibrating screen 15 further performs secondary fine filtration to completely remove the graphite powder that does not meet the standards, ultimately achieving continuous and high-purity collection of graphite powder, effectively improving the product qualification rate and collection efficiency.

[0022] Reference Figure 2 The inner core 10 has a spiral groove on its surface, and the inner wall of the outer cylinder 2 has a spiral protrusion. The surface of the grinding ball 11 is slidably connected to the surface of the spiral protrusion.

[0023] Specifically, the spiral grooves on the surface of the inner core 10 cooperate with the spiral protrusions on the inner wall of the outer cylinder 2, allowing the grinding balls 11 to slide along the contact surface between the two. This significantly enhances the crushing effect of the grinding balls 11 on the graphite, improves the grinding uniformity, and at the same time, the spiral structure can guide the movement of materials, avoid local accumulation, achieve efficient material flow and thorough grinding, and further enhance the grinding effect.

[0024] Reference Figure 2 The two ends of the transmission gear rod 6 are rotatably connected to the inner wall of the machine body 1. Multiple gears are provided on the surface of the transmission gear rod 6. One gear of the transmission gear rod 6 is meshed with the outer wall of the first impeller 7, and the other gear of the transmission gear rod 6 is meshed with the outer wall of the outer cylinder 2.

[0025] Specifically, the two ends of the transmission gear rod 6 are rotatably connected to the inner wall of the machine body 1. Through the surface multi-gear meshing with the first impeller 7 and the outer cylinder 2 respectively, the power of the first impeller 7 can be accurately transmitted, ensuring that the outer cylinder 2 and the inner core 10 achieve stable reverse synchronous rotation, thus ensuring the reliability of the grinding core action.

[0026] Reference Figure 1 The outer wall of the machine body 1 is provided with a feeding port.

[0027] Specifically, a feeding port is opened on the outer wall of the machine body 1, which allows materials to be directly and conveniently put into the feeding port 9.

[0028] Reference Figure 4 One end of the transmission rod 12 is provided with a protrusion, and the upper surface of the vibrating screen 15 is provided with a protrusion.

[0029] Specifically, when the transmission rod 12 rotates, the protrusions on its surface cooperate with the protrusions on the surface of the vibrating screen 15 to achieve the vibration of the vibrating screen 15.

[0030] Reference Figure 3 The outer wall of the collection chamber 3 has an annular opening, and the inner wall of the screening chamber 4 is set on the surface of the annular opening.

[0031] Specifically, the outer wall of the collection chamber 3 has an annular opening, and the inner wall of the screening chamber 4 is directly fitted onto the surface of the opening, achieving a seamless connection between the screening chamber 4 and the collection chamber 3. This allows the unqualified materials after screening to quickly enter the interior of the screening chamber 4 through the annular opening and undergo secondary grinding by the grinding device.

[0032] Working principle: When using this device, graphite blocks are first fed into the feed inlet 9 above the outer cylinder 2 through the feed port on the outer wall of the machine body 1. The motor 5 drives the first impeller 7 to rotate. The first impeller 7 meshes with and drives the second impeller 8 and the inner core 10 to rotate. At the same time, the linkage transmission gear rod 6 causes the outer cylinder 2 to rotate in the opposite direction. The spiral groove on the surface of the inner core 10 and the spirally set protrusion on the outer cylinder 2 make the grinding ball 11 rotate, forming a dual grinding force to efficiently grind the graphite.

[0033] After grinding, the inner core 10 drives the transmission rod 12 to rotate, and the scraper 13 scrapes the graphite powder onto the rotating screen 14. Centrifugal force separates the substandard graphite powder into the screening chamber 4 for secondary grinding. When the qualified powder falls, the protrusion of the transmission rod 12 cooperates with the protrusion of the vibrating screen 15 to make it vibrate. After secondary filtration, the qualified graphite powder is collected in the collection chamber 3.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
