[0002] Graphite is an allotrope of carbon. It is a gray-black, opaque solid with stable chemical properties, corrosion resistance, and does not react easily with acids, alkalis and other agents. Natural graphite comes from graphite deposits, and it can also be made into artificial graphite using petroleum coke, asphalt coke and other raw materials through a series of processing steps.

[0003] Graphite sintering is to treat powdered graphite materials at high temperatures to form a solid with a certain density and structure. A high-temperature sintering furnace is required for graphite sintering. In the prior art, most high-temperature sintering furnaces do not have components for dissipating heat from the sintered spherical graphite particles after sintering the spherical graphite particles, resulting in the sintered spherical graphite particles having a high temperature, which affects the feeding, thereby reducing the sintering efficiency of the spherical graphite particles and is not practical enough. Therefore, it is necessary to redesign a high-temperature sintering furnace for spherical graphite particles in view of the above problems. Utility Model Content

[0023] The first limiting mechanism includes a first limiting rod 7 fixedly installed inside the moving groove. The first limiting rod 7 slides through the moving sleeve 8. The first limiting rod 7 can limit the moving sleeve 8 so that the moving sleeve 8 can only move axially along the outer wall of the first screw rod 5.

[0024] The outer wall of the movable sleeve 8 is fixedly connected with the cover plate 10 through a connecting mechanism. The connecting mechanism includes a connecting rod 9 fixedly installed on the outer wall of the movable sleeve 8. The end of the connecting rod 9 is fixedly connected to the outer wall of the cover plate 10. A sealing ring 11 is fixedly installed on the inner wall of the cover plate 10. The sealing ring 11 is made of vulcanized rubber. Vulcanized rubber refers to vulcanized rubber, which has the characteristics of not becoming sticky and not being easy to break. Most rubber products are made of this rubber, and it also has high elasticity, heat resistance, tensile strength and insolubility in organic solvents.

[0025] A sintering box 12 is fixedly mounted on the inner wall of the cover plate 10, a lifting plate 13 is slidably mounted inside the sintering box 12, a connecting plate 15 is mounted on the upper end surface of the base 1 through a lifting mechanism, and the lifting mechanism includes a cylinder 14 fixedly mounted on the upper end surface of the base 1, and the telescopic end of the cylinder 14 is fixedly connected to the bottom wall of the connecting plate 15.

[0026] A plurality of lifting rods 16 are fixedly mounted on the upper end surface of the connecting plate 15, and a plurality of lifting holes 17 cooperating with the lifting rods 16 are provided on the bottom wall of the sintering box 12. A second screw 18 is rotatably mounted on the upper end surface of the base 1 through a rotating groove, and the second screw 18 is a double-headed screw. A motor 19 cooperating with the second screw 18 is fixedly mounted on the outer wall of the base 1, and two movable plates 21 are threadedly mounted on the outer wall of the second screw 18 through a second limiting mechanism. The second limiting mechanism includes a second limiting rod 20 fixedly mounted inside the rotating body, and the second limiting rod 20 slides through the two movable plates 21. The second limiting rod 20 can limit the two movable plates 21, so that the two movable plates 21 can only move axially along the outer wall of the second screw 18, and the inner walls of the two movable plates 21 are fixedly mounted with a cooling fan 23 through a connecting rod 22.

At this time, the two coolers 23 can blow air to dissipate heat for the sintered spherical graphite particle raw materials inside the sintering box 12, thereby increasing the heat dissipation rate of the spherical graphite particle raw materials. Then the cylinder 14 can drive the connecting plate 15 to move, and the connecting plate 15 drives the multiple lifting rods 16 to move in the lifting hole 17. Through the cooperation of the multiple lifting rods 16, the lifting plate 13 can be pushed to move upward inside the sintering box 12, thereby driving the cooled spherical graphite particle raw materials to move upward inside the sintering box 12 through the lifting plate 13, so as to facilitate unloading.
