[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0027] Reference Figures 1-5A petroleum coke calcining device with rotary calcination includes a fixed plate 1 and a fixed shell 2. The fixed shell 2 is fixedly connected to the top of the fixed plate 1. The fixed plate 1 provides fixing points for the fixed shell 2, support plate 6, and support foot 11 fixedly connected to its outer surface. The fixed shell 2 provides connection points for the calcining shell 3 fitted inside it, and also provides fixing points for the geared motor 17 fixedly connected to its outer surface. The calcining shell 3 is rotatably connected to the inner side of the fixed shell 2. The calcining shell 3 is rotatably connected to the inner side of the fixed shell 2, providing calcination space for the raw materials injected inside it, and also provides fixing points for the first shielding shell 4, the second shielding shell 5, the shielding cover 10, and the driven wheel 19 connected to its outer surface. The first shielding shell 3 is fitted to one side of its outer surface. A first shielding shell 4 is fitted into the calcining shell 3, providing shielding on one side of the calcining shell 3 and providing fixing points for the air intake pipe 7, blower 8, and igniter 9, which are fixedly connected to its outer and inner surfaces. A second shielding shell 5 is fitted into the other side of the calcining shell 3, providing shielding on the other side and providing fixing points for the output pipe 12, which is fixedly connected to its outer surface. Support plates 6 are fixedly connected to the outer sides of both the first shielding shell 4 and the second shielding shell 5. The support plates 6 are connected to the first shielding shell 4 and the second shielding shell 5 respectively, and also to the fixing plate 1, thus fixing the first shielding shell 4 and the second shielding shell 5. The support plates 6 are connected to the fixing plate 1. Next, an air inlet pipe 7 is connected through one side of the first shielding shell 4. The air inlet pipe 7 is connected through one side of the first shielding shell 4 and connected to an external pipe to deliver gas to the inside of the calcining shell 3. The air inlet pipe 7 is located behind the support plate 6. A blower 8 is connected through one side of the first shielding shell 4. When air needs to be supplied to the inside of the calcining shell 3, electrical energy can be supplied to the blower 8 through an external control component. At this time, the blower 8 generates suction force on the air in the external environment and continuously delivers air to the inside of the calcining shell 3 to replenish the air in the calcining shell 3. The blower 8 is located in front of the support plate 6. An igniter 9 is fixedly connected to the inside of the first shielding shell 4. Inside the calcining shell 3, after the gas is delivered to the inside of the calcining shell 3, electrical energy can be delivered to the inside of the igniter 9 through an external control component. At this time, the igniter 9 generates an electric spark to ignite the gas and continuously conduct heat to the inside of the calcining shell 3. The top of the calcining shell 3 is threaded with a shielding cover 10, which provides shielding for the top of the calcining shell 3 and provides output space for petroleum coke inside the calcining shell 3. At the same time, it provides space for raw materials to be injected into the inside of the calcining shell 3. The bottom of the fixing plate 1 is fixedly connected with a support foot 11, which is fixedly connected to the bottom of the fixing plate 1. The support force transmitted to its interior through the ground provides support for the whole device, and four support feet 11 are provided.

[0028] Reference Figure 1 , Figure 2 and Figure 7 An output pipe 12 is connected through the other side of the second shielding shell 5. The output pipe 12 provides a fixing point for the exhaust shell 13, which is fixedly connected to its tail end. When the air pressure inside the calcining shell 3 is too high, the output pipe 12 delivers the exhaust gas to the interior of the exhaust shell 13. The output pipe 12 is located above the support plate 6. The exhaust shell 13 is fixedly connected to the tail end of the output pipe 12. The exhaust shell 13 is connected through the tail end of the output pipe 12, providing a fixing point for the ventilation fan 14, the first filter layer 15, and the second filter layer 16, which are fixedly connected to its inner side. At the same time, it provides space for the exhaust gas to be output to the external environment. The ventilation fan 14 is fixedly connected to the inner side of the exhaust shell 13. When it is necessary to output the exhaust gas, electrical energy can be transmitted through an external control component. The exhaust gas flows into the ventilation fan 14, where it draws in the exhaust gas from the output pipe 12 and the inner side of the calcining shell 3, and delivers the exhaust gas to the external environment to complete the exhaust gas output. A first filter layer 15 is fixedly connected to the inner side of the exhaust shell 13. The first filter layer 15 is made of multiple layers of filter cloth. When the exhaust gas is delivered into the interior of the exhaust shell 13, the first filter layer 15 intercepts large particulate impurities inside the exhaust shell 13. A second filter layer 16 is fixedly connected to the inner side of the exhaust shell 13. The second filter layer 16 is made of activated carbon. When the exhaust gas is delivered into the interior of the exhaust shell 13, the second filter layer 16 intercepts pollutants inside the exhaust shell 13, thereby completing the exhaust gas treatment. The second filter layer 16 is located above the first filter layer 15.

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 A geared motor 17 is fixedly connected to the other side of the fixed shell 2. When it is necessary to perform rotary calcination of the petroleum coke inside the calcination shell 3, electrical energy can be transmitted to the inside of the geared motor 17 through an external control component. At this time, the geared motor 17 transmits the rotational power to the inside of the transmission wheel 18. The output end of the geared motor 17 is fixedly connected to the transmission wheel 18. When the rotational power is transmitted to the inside of the transmission wheel 18 through the geared motor 17, the transmission wheel 18 rotates and transmits the rotational power to the inside of the driven wheel 19. The driven wheel 19 is fixedly connected to the outer surface of the calcination shell 3. When the rotational power is transmitted to the inside of the driven wheel 19 through the transmission wheel 18, the driven wheel 19 rotates, causing the calcination shell 3 to rotate and the petroleum coke to be calcined in a rotary manner. The driven wheel 19 meshes with the surface of the transmission wheel 18.

[0030] Reference Figures 3-5 The inner walls of the calcining shell 3, the first shielding shell 4, and the second shielding shell 5 are all equipped with heat insulation layers 20. The heat insulation layers 20 are made of heat insulation cotton. During the calcination of petroleum coke, they can block the rapid conduction of heat to the external environment, thereby reducing the energy consumption required for heating during the calcination process and improving the calcination effect of the device.

[0031] The functional principle of this utility model can be explained by the following operation: First, the raw material is injected into the inside of the calcining shell 3 by rotating the cover 10 with external force. Then, the cover 10 is fixed to the top of the calcining shell 3. Then, the air inlet pipe 7 is connected to the external pipe by external force. At this time, the air inlet pipe 7 delivers the gas to the inside of the calcining shell 3. The blower 8 generates suction to the air in the external environment and continuously delivers air to the inside of the calcining shell 3 to replenish the air in the calcining shell 3. The igniter 9 generates an electric spark to ignite the gas and continuously conduct heat to the inside of the calcining shell 3 to complete the calcination of petroleum coke. After the calcination is completed, the petroleum coke is removed by rotating the cover 10 again with external force to complete the output of petroleum coke.
