Description

Technical Field

[0001] This invention relates to the field of graphite purification technology, and more specifically, to a continuous graphite purification apparatus. Background Technology

[0002] A continuous graphite purification device is a type of equipment used to improve the quality of graphite. It mainly processes raw graphite through physical separation processes to remove impurities and harmful substances, thereby obtaining pure graphite products. High-temperature graphitization is a process in which carbon materials undergo physical processes under high-temperature conditions to transform into graphite. This type of equipment is used to achieve graphite purification.

[0003] A search of existing publicly available literature revealed that Chinese Patent Publication No. CN210885323U discloses a continuous high-temperature purification device, targeting purification processes commonly used in the industry, including the Atchison process and continuous high-temperature graphitization. The Atchison process has many inherent drawbacks, including low efficiency, indirect and cyclical production, and long single-batch delivery cycles. This device utilizes a dual-channel structure to achieve heat exchange between the first and second cavities, improving energy utilization while saving graphite cooling time. It also reduces the height of the continuous high-temperature purification device and effectively utilizes space. However, this graphite purification device has the following shortcomings.

[0004] In the above-mentioned graphite purification device, the graphite powder raw material is directly injected into the purification equipment for purification. It is difficult to accurately control the quality of the graphite powder raw material, which easily leads to the accumulation of graphite powder raw material during feeding. If the feeding amount is too large, there will be too much graphite powder raw material, resulting in poor uniformity of graphite powder raw material purification. Therefore, a continuous graphite purification device is needed. Summary of the Invention

[0005] To overcome the above-mentioned defects of the prior art, the present invention provides a continuous graphite purification device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a continuous graphite purification device, comprising a quantitative purification box, wherein a quantitative lower discharge cylinder is rotatably connected inside the quantitative purification box, and multiple quantitative receiving slots are embedded in the outer wall of the quantitative lower discharge cylinder in an annular pattern at equal intervals, and a quantitative feeding mechanism is installed on the inner wall of the quantitative receiving slots;

[0007] The quantitative feeding mechanism includes a weighing plate installed on the inner wall of the quantitative receiving tank. A weighing sensor is fixedly connected to the bottom end of the weighing plate. The inner wall of the quantitative discharge cylinder is provided with a switching column for supporting multiple weighing sensors. One end of the switching column extends to the outer wall of the quantitative purification chamber and is welded with a drive shaft. A geared motor is coaxially connected to one end of the drive shaft. A uniform dispensing component is installed above the quantitative purification chamber. A dispersion heating component is welded to the bottom end of the quantitative purification chamber.

[0008] Preferably, the weighing sensor and the quantitative lower discharge cylinder are both fixedly connected to the switching column, the quantitative lower discharge cylinder and the weighing plate are both made of ceramic material, the weighing plate is vertically slidably connected to the quantitative lower discharge cylinder to which the quantitative receiving groove belongs, and the top width of the inner wall of the quantitative receiving groove is greater than the bottom width of its bottom inner wall.

[0009] Preferably, the outer wall of the quantitative purification chamber is provided with a support base for vertical support of the geared motor. The support base is fixedly connected to the quantitative purification chamber and the geared motor respectively. A sensing end is installed at the other end of the weighing plate, penetrating the quantitative purification chamber. An angle sensor is coaxially fixedly connected to one end of the sensing end. The cross-sectional area of ​​the upper surface of the weighing plate is larger than the cross-sectional area of ​​its bottom end. Limiting blocks are provided on the inner wall of the quantitative receiving tank and on both sides of the weighing plate. The limiting blocks are welded to the quantitative lower cylinder to which the quantitative receiving tank belongs. An arc-shaped guide plate and an arc-shaped guide support plate are arranged sequentially from right to left below the quantitative lower cylinder. The arc-shaped guide support plate and the arc-shaped guide plate are rotatably connected to the quantitative lower cylinder, and the arc-shaped guide plate and the arc-shaped guide support plate are symmetrically arranged about the switching column.

[0010] By adopting the above technical solution, the surface of the weighing plate can be weighed by the weighing end of the weighing sensor. When the weighing value of the weighing sensor reaches the set weight value, the reduction motor drives the drive shaft to rotate on the quantitative purification box. The switching column and the quantitative discharge cylinder rotate the graphite purification powder raw material inside the quantitative container tank by 36 degrees. In this way, another quantitative container tank located below the graphite raw material container continues to hold the graphite purification powder raw material. The switching column drives the sensing end to rotate. The sensing end has an angle sensor to sense the angle and accurately control the rotation angle of the quantitative discharge cylinder to 36 degrees. Each quantitative container tank can rotate 36 degrees after holding the graphite purification powder raw material until the graphite purification powder raw material in the uppermost quantitative container tank rotates into the gap between the arc-shaped guide plate and the arc-shaped guide plate. The graphite purification powder raw material is then quantitatively discharged into the container tank, realizing quantitative discharge.

[0011] Preferably, the uniform distribution assembly includes a graphite raw material receiving hopper installed above the quantitative purification box. A linkage bracket is welded to one side of the outer wall of the graphite raw material receiving hopper, and a linkage collar frame is welded to the other side of the outer wall of the graphite raw material receiving hopper. A threaded collar block is fixedly connected to the bottom end of the linkage bracket. A threaded transmission rod is threadedly connected inside the threaded collar block. A guide frame plate is horizontally slidably connected to the outer wall of the threaded collar block. One end of the threaded transmission rod extends to the front of the guide frame plate and is coaxially driven by a reduction drive motor. A guide support is horizontally slidably connected to the inner wall of the guide frame plate near its bottom end.

[0012] By adopting the above technical solution, the starting reduction drive motor drives the threaded transmission rod to rotate forward and then reverse inside the guide frame plate. As a result, the threaded transmission rod drives the threaded collar block to move forward and then backward along the guide frame plate under the action of the thread. The threaded collar block drives the linkage bracket to move the graphite raw material receiving hopper back and forth. At the same time, the graphite raw material receiving hopper drives the linkage collar frame to move back and forth along the outer wall of the guide pillar. The graphite raw material receiving hopper discharges the graphite purified powder raw material onto the upper surface of the weighing plate, so that the graphite purified powder raw material can be evenly spread on the surface of the weighing plate.

[0013] Preferably, the dispersion heating assembly includes a container cylinder welded to the bottom of the quantitative purification chamber. An insulation plate is fixedly connected to the outer wall of the container cylinder. A resistance heating rod for heating the container cylinder is installed inside the insulation plate. An exhaust pipe with an L-shaped vertical cross-section is welded to the outer wall of the container cylinder near its top. A dispersion support is installed on the inner wall of the container cylinder at its center point. Multiple dispersion heat-conducting plates are arranged in a ring at equal intervals between the outer wall of the dispersion support and the inside of the container cylinder. Each dispersion heat-conducting plate has an inclined heat-conducting plate with a triangular vertical cross-section welded to its top.

[0014] By adopting the above technical solution, the insulation layer plate keeps the resistance heating rod warm, the resistance heating rod heats the inside of the container cylinder, the dispersion support column and multiple dispersion heat conduction plates conduct heat, and the dispersion heat conduction plates conduct heat to the inclined heat conduction plates. When the graphite purification powder raw material enters the container cylinder, multi-interval material separation and purification are achieved, and the purified waste gas is discharged along the container cylinder to the waste gas discharge pipe.

[0015] The technical effects and advantages of this invention are as follows:

[0016] 1. This invention employs a quantitative feeding mechanism so that the surface of the weighing plate can be weighed by the weighing end of the weighing sensor. When the weighing value of the weighing sensor reaches the set weight value, the reduction motor drives the drive shaft to rotate on the quantitative purification box. The switching column and the quantitative lower cylinder rotate the graphite purification powder raw material inside the quantitative container tank by 36 degrees. The sensing end has an angle sensor to sense the angle and accurately control the rotation angle of the quantitative lower cylinder to 36 degrees. This ensures that the graphite powder raw material is accurately added every time, the graphite powder raw material is heated more evenly and is less prone to accumulation, and the purification uniformity is better.

[0017] 2. This invention uses a uniform material distribution component to start a reduction drive motor that drives a threaded transmission rod to rotate forward and then reverse inside the guide frame plate. The threaded transmission rod drives the threaded collar block to move forward and then backward along the guide frame plate under the action of the thread. The threaded collar block drives the linkage bracket to move the graphite raw material receiving hopper back and forth. The graphite raw material receiving hopper drives the linkage collar frame to move back and forth along the outer wall of the guide pillar. The graphite powder raw material entering the quantitative receiving tank is evenly fed, ensuring more uniform heat purification and preventing accumulation.

[0018] 3. This invention uses a dispersed heating component to keep the insulation layer plate insulated from the resistance heating rod, which in turn heats the inside of the container. The dispersed heat-conducting plate conducts heat through the inclined heat-conducting plate. When the graphite purification powder raw material enters the container, it achieves multi-interval material separation and purification, continuous purification contact from top to bottom, and multi-point contact heat conduction, increasing the heating area of ​​the graphite powder raw material. Furthermore, each point is heated sequentially and separately, resulting in more uniform heating of the purified graphite powder raw material.

[0019] In summary, through the interaction of the above-mentioned multiple functions, the graphite raw material receiving hopper first drives the linkage ring frame to move back and forth along the outer wall of the guide pillar. When the weight value measured by the weighing sensor reaches the set weight value, the reduction motor drives the drive shaft to rotate on the quantitative purification box. Finally, through multi-interval material distribution purification, the purification contacts are continuously purified from top to bottom. In summary, this can effectively improve the uniformity of graphite purification, prevent the accumulation of graphite purification raw materials, and achieve better purification results.

Limiting blocks 14 are provided on the inner wall of the quantitative receiving tank 3 at positions on both sides of the weighing plate 4. The limiting blocks 14 are connected to... The quantitative loading tank 3 is welded to the quantitative lower cylinder 2 so that the graphite purification powder raw material can be limited by two limiting blocks 14. The graphite purification powder raw material can be evenly spread on the upper surface of the weighing plate 4. The lower part of the quantitative lower cylinder 2 is provided with an arc-shaped guide plate 10 and an arc-shaped guide support plate 13 from right to left. The arc-shaped guide support plate 10 and the arc-shaped guide support plate 13 are rotatably connected to the quantitative lower cylinder 2. The arc-shaped guide plate 10 and the arc-shaped guide support plate 13 are symmetrically arranged about the switching column 6 so that the graphite purification powder raw material inside the uppermost quantitative loading tank 3 can rotate into the gap between the arc-shaped guide support plate 13 and the arc-shaped guide plate 10. The arc-shaped guide plate 10 and the arc-shaped guide support plate 13 limit and guide the material in the quantitative lower cylinder 2.

[0031] In some embodiments, as shown in the appendix Figure 1-4As shown, the uniform material distribution assembly includes a graphite raw material container 15 installed above the quantitative purification box 1. A linkage bracket 16 is welded to one side of the outer wall of the graphite raw material container 15, and a linkage collar frame 21 is welded to the other side of the outer wall of the graphite raw material container 15. A threaded collar block 17 is fixedly connected to the bottom end of the linkage bracket 16. A threaded transmission rod 18 is threadedly connected inside the threaded collar block 17. A guide frame plate 20 is horizontally slidably connected to the outer wall of the threaded collar block 17. One end of the threaded transmission rod 18 extends to the front of the guide frame plate 20 and is coaxially driven by a reduction drive motor 19. A guide support column 22 is horizontally slidably connected to the inner wall of the guide frame plate 20 near its bottom end.

[0032] In some embodiments, as shown in the appendix Figure 1-6 As shown, the dispersion heating assembly includes a container cylinder 23 welded to the bottom of the quantitative purification chamber 1. An insulation plate 24 is fixedly connected to the outer wall of the container cylinder 23. A resistance heating rod 26 for heating the container cylinder 23 is installed inside the insulation plate 24. An exhaust pipe 25 with an L-shaped vertical cross-section is welded to the outer wall of the container cylinder 23 near its top. A dispersion support column 27 is installed on the inner wall of the container cylinder 23 at its center point. Multiple dispersion heat-conducting plates 28 are arranged in a circular and equidistant manner between the outer wall of the dispersion support column 27 and the interior of the container cylinder 23. Each dispersion heat-conducting plate 28 has an inclined heat-conducting plate 29 with a triangular vertical cross-section welded to its top.

[0033] The working principle of the continuous graphite purification device of this invention is as follows:

[0034] During uniform feeding, the graphite purified powder raw material is poured into the graphite raw material receiving hopper 15. The reduction drive motor 19 is started to drive the threaded transmission rod 18 to rotate forward and then reverse inside the guide frame plate 20. As a result, the threaded transmission rod 18 drives the threaded collar block 17 to move forward and then backward along the guide frame plate 20 under the action of the thread. The threaded collar block 17 drives the linkage bracket 16 to move the graphite raw material receiving hopper 15 back and forth. At the same time, the graphite raw material receiving hopper 15 drives the linkage collar frame 21 to move back and forth along the outer wall of the guide pillar 22. The graphite raw material receiving hopper 15 discharges the graphite purified powder raw material to the upper surface of the weighing plate 4. The two limiting blocks 14 limit the graphite purified powder raw material, so that the graphite purified powder raw material can be evenly spread on the upper surface of the weighing plate 4.

[0035] During quantitative feeding, the upper surface of the weighing plate 4 can be weighed by the weighing end of the weighing sensor 5. When the weighing value of the weighing sensor 5 reaches the set weight value, the support base 9 provides vertical support for the reduction motor 8. The reduction motor 8 drives the drive shaft 7 to rotate on the quantitative purification box 1. The switching column 6 and the undetermined quantitative lower discharge cylinder 2 rotate the graphite purification powder raw material inside the quantitative receiving tank 3 by 36 degrees. In this way, another quantitative receiving tank 3 is located below the graphite raw material receiving hopper 15 to continue to receive the graphite purification powder raw material. The switching column 6 drives the... The motion sensing end 11 rotates, and the sensing end 11 has an angle sensor 12 to sense the angle, precisely controlling the rotation angle of the quantitative lower discharge cylinder 2 to thirty-six degrees. Each quantitative receiving tank 3 can rotate thirty-six degrees after it is filled with graphite purified powder raw material, until the graphite purified powder raw material inside the uppermost quantitative receiving tank 3 rotates into the gap between the arc-shaped guide plate 13 and the arc-shaped guide plate 10. The graphite purified powder raw material is quantitatively discharged into the receiving cylinder 23, while the arc-shaped guide plate 10 and the arc-shaped guide plate 13 play a limiting role on the outer wall of the quantitative lower discharge cylinder 2.

[0036] During heating and purification, the insulation layer 24 keeps the resistance heating rod 26 warm, and the resistance heating rod 26 heats the inside of the container 23. Heat is conducted through the dispersion support 27 and multiple dispersion heat conduction plates 28, and the inclined heat conduction plate 29 is also conducted by the dispersion heat conduction plates 28. When the graphite purification powder raw material enters the container 23, it achieves multi-interval material separation and purification, and continuous purification contact from top to bottom. This can purify the graphite purification powder raw material. The purified waste gas is discharged upward along the container 23 into the waste gas discharge pipe 25, and the waste gas is discharged upward by the waste gas discharge pipe 25.
