Description

Technical Field

[0001] This utility model relates to the field of spherical graphite preparation technology, and in particular to a high-pH heat treatment device for spherical graphite. Background Technology

[0002] Spherical graphite is a specially processed graphite material, mainly made from high-quality, high-carbon natural flake graphite. It is prepared through multiple steps, including high pH value treatment and heat treatment. During the heat treatment of spherical graphite, the graphite raw material that has undergone high pH value treatment needs to be heated using a heat treatment device.

[0003] Patent CN215559028U discloses a heat treatment device for producing spherical graphite anode materials. The device includes a main body, which includes a conveyor belt and a heat treatment chamber installed on one side of the conveyor belt. A heating pipe is provided above the conveyor belt and the heat treatment chamber, and a discharge port is provided on one side of the heat treatment chamber. A limiting mechanism is provided above the conveyor belt, and the limiting mechanism includes baffles. Baffles are installed on both the front and rear sides of the top of the conveyor belt, and protrusions are fixed on both sides of the inner side of the baffles. A rotating rod is movably connected between the two sets of protrusions through bearings, and limiting blocks are fixed at equal intervals on the outer surface of the rotating rod.

[0004] In the above case, graphite is transported to the heat treatment chamber by a conveyor belt for heat treatment. However, the heat treatment chamber is not a sealed structure, which causes heat loss, increases the energy consumption of the device, reduces the heat treatment efficiency of graphite, and makes the device impractical.

[0005] Therefore, this utility model provides a high-pH heat treatment device for spherical graphite to meet the requirements. Utility Model Content

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

[0024] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0025] Please see Figures 1-4This utility model provides a high-pH heat treatment device for spherical graphite, including a treatment tank 1 for heat treatment of spherical graphite. The top and bottom of the treatment tank 1 are fixedly connected to connecting pipes 2, and the other end of the connecting pipes 2 is fixedly connected to a transfer tank 3. There are two connecting pipes 2 and two transfer tanks 3. The upper and lower ends of the treatment tank 1 are fixedly connected to sealing components for opening and closing the connecting pipes 2. The inner sides of the treatment tank 1 are fixedly connected to two side seats 7, and the other end of the side seats 7 is slidably connected to an outer frame 8. The outer seat 7 includes a retaining sleeve fixedly connected at both ends. The outer frame 8 is slidably connected to the side seats 7 via the retaining sleeve. The two outer frames 8 are fixedly connected to the same bearing component. The sealing component includes a cylinder fixedly connected to the upper and lower ends of the treatment tank 1. 5. A partition 6 is fixedly connected to the output end of cylinder 5. Two partitions 6 are slidably connected to the inside of the connecting pipe 2 on the same side. The partition 6 is tightly fitted to the outside of the treatment tank 1. The partition 6 includes a sealing sleeve fixedly connected to the outside. The area of ​​the partition 6 inside the connecting pipe 2 is larger than the area inside the connecting pipe 2. The bearing assembly includes an annular sleeve 9 fixedly connected between two outer frames 8. A base plate 10 is rotatably connected to the bottom of the inner side of the annular sleeve 9. The base plate 10 includes rotating shafts 11 fixedly connected to both sides. A gas conveying assembly for conveying inert gas is fixedly connected to one side of the treatment tank 1. The gas conveying assembly includes an air pump 4 fixedly connected to the outside of the treatment tank 1. The output end of the air pump 4 is fixedly connected to an air pipe that extends into the inside of the treatment tank 1.

[0026] Turn on the air pump 4 to extract the inert gas from the external storage device connected to it and deliver the inert gas into the processing tank 1 through the air pipe. The air in the tank is discharged from the connecting pipe 2 and the transfer tank 3 to prevent the graphite from oxidizing during heat treatment. Then, the cylinder 5 controls the movement of the partition 6 to seal the two connecting pipes 2. Add the high pH value spherical graphite raw material to be treated into the transfer tank 3 above the processing tank 1. Then seal the transfer tank 3. The cylinder 5 drives the upper partition 6 to move, so that the graphite enters the interior of the processing tank 1 from the connecting pipe 2 and falls into the annular sleeve 9 located below it.

[0027] By using cylinder 5 to drive partition 6, the inside of connecting pipe 2 can be sealed and opened. The introduction of transfer tank 3 provides an independent transfer space for the addition and unloading of graphite, so that the loading and unloading process of graphite needs to be carried out in transfer tank 3, and will not be carried out directly inside processing tank 1. In this way, processing tank 1 can always maintain good airtightness, effectively avoiding heat loss and leakage of inert gas, thereby significantly improving the practicality of the device and heat treatment efficiency. This structural design not only optimizes the operation process, but also reduces energy consumption and enhances the stability and reliability of the entire device.

[0028] Please see Figures 1-4One of the side seats 7 is rotatably connected to a rotating disk 12 on its inner side, and a connecting rod 13 is fixedly connected to its outer side. A drive rod 14 is rotatably connected to the outer side of the connecting rod 13. The other end of the drive rod 14 is rotatably connected to the outer frame 8 on the same side. A soft pad is fixedly connected to the outer side of the base plate 10, which fits tightly against the inner side of the annular sleeve 9. The end of the rotating shaft 11 away from the base plate 10 passes through the annular sleeve 9. A first motor is fixedly connected to the outer side of the annular sleeve 9, and its output end is fixedly connected to one of the rotating shafts 11. When the first motor is not started, the rotating shaft 11 connected to it will not rotate, which can prevent shaking during heating. A second motor is fixedly connected to the inner side of the side seat 7 near the rotating disk 12, and its output end is fixedly connected to the rotating disk 12. An electric heating ring 16 and a funnel frame 15 are fixedly connected to the upper and lower parts of the bearing component on the inner side of the processing tank 1, respectively. The bottom end of the funnel frame 15 is fixedly connected to the connecting pipe 2 located at the bottom end.

[0029] Start motor 2 to rotate the rotating disk 12. Through connecting rod 13 and drive rod 14, move the outer frame 8 back and forth on the side seat 7. Shake the annular sleeve 9 to evenly distribute the graphite on the base plate 10. Start the heating ring 16 to heat-treat the graphite in the processing tank 1. After cooling, start motor 1 to rotate the base plate 10 and pour the graphite into the funnel frame 15. The soft pad not only ensures the seal between the base plate 10 and the annular sleeve 9, but also deforms to facilitate the rotation of the base plate 10. The graphite enters the connecting pipe 2 below from the funnel frame 15. Start cylinder 5 below to move the partition 6. The graphite enters the transfer tank 3 below the processing tank 1. Cylinder 5 reverses and seals the connecting pipe 2 below through the partition 6. Open the valve fixedly connected to the bottom of the transfer tank 3 below the processing tank 1 to discharge the spherical graphite.

[0030] The rotation of the rotating disk 12 drives the drive rod 14 via the connecting rod 13, which in turn drives the outer frame 8 to move back and forth repeatedly on the side seat 7. This allows the graphite inside the annular sleeve 9 to be evenly spread on the base plate 10 during the shaking process, avoiding local accumulation or uneven heating of the graphite during heating. This uniform distribution greatly improves the heating efficiency of the graphite, ensuring the uniformity and consistency of the heat treatment, thereby significantly improving the overall efficiency of the heat treatment. The base plate 10 is connected to the No. 1 motor via the rotating shaft 11, and can rotate under the drive of the motor. It is designed in conjunction with the funnel frame 15, allowing the processed graphite to slide more smoothly from the annular sleeve 9 into the funnel frame 15, and finally enter the transfer tank 3 through the connecting pipe 2 to complete the feeding process.

[0031] The working principle and usage process of this utility model are as follows: the air pump 4 is turned on to extract the inert gas from the external storage device connected to it and deliver the inert gas into the processing tank 1 through the air pipe to discharge the air in the tank, so as to prevent the graphite from oxidizing during heat treatment. Then, the cylinder 5 controls the movement of the partition 6 to seal the two connecting pipes 2, and adds the high pH value spherical graphite raw material to be processed into the transfer tank 3 above the processing tank 1. The transfer tank 3 is sealed, and the cylinder 5 drives the upper partition 6 to move, so that the graphite enters the processing tank 1 from the connecting pipe 2 and falls into the annular sleeve 9 located below it.

[0032] Start motor 2 to rotate the rotating disk 12. Through connecting rod 13 and drive rod 14, move the outer frame 8 back and forth on the side seat 7. Shake the annular sleeve 9 to evenly distribute the graphite on the base plate 10. Start the heating ring 16 to heat-treat the graphite in the processing tank 1. After cooling, start motor 1 to rotate the base plate 10 and pour the graphite into the funnel frame 15. The soft pad not only ensures the seal between the base plate 10 and the annular sleeve 9, but also deforms to facilitate the rotation of the base plate 10. The graphite enters the connecting pipe 2 below from the funnel frame 15. Start cylinder 5 below the processing tank 1 to move the partition 6. The graphite enters the transfer tank 3 below the processing tank 1. Cylinder 5 reverses and seals the connecting pipe 2 below through the partition 6. Open the valve fixedly connected to the bottom of the transfer tank 3 below to discharge the spherical graphite.

[0033] In the above scheme, it should be noted that: both motor 1 and motor 2 are equipped with high-temperature resistant heat insulation protective covers (this is a conventional method in the prior art), which can prevent motor 1 and motor 2 from being damaged due to heat. At the same time, the heating ring 16 is made of ultra-high purity graphite material, that is, the heating ring 16 is the existing "graphite heating element", which can make the heat generated by the heating ring 16 meet the heat treatment requirements of spherical graphite. The heating ring 16 is electrically connected to the external circuit through wires.

[0034] It should also be noted that the heat treatment apparatus of this application is equipped with an existing temperature control system, which can control the heat treatment temperature of the spherical graphite inside the treatment tank 1. Since the temperature control system is an existing technology and the improvement of this application does not involve the design of the temperature control system, the temperature control system will not be described in detail.

[0035] Although 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 alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
