[0002] The calcining furnace for raw coke is a core piece of equipment in carbon production. Its main function is to perform high-temperature heat treatment on raw petroleum coke (or raw pitch coke). This process can effectively remove volatile matter, moisture, and some impurities from the raw coke, thereby improving its physical and chemical properties, such as increasing its fixed carbon content, reducing resistivity, enhancing mechanical strength and chemical stability, and providing qualified raw materials for the subsequent production of carbon products (such as anodes for electrolytic aluminum and graphite electrodes).

[0003] Traditional calcining furnaces often generate a lot of dust during the feeding process. If a large amount of this dust enters the calcining furnace, it will adhere to the furnace body components, reducing product quality and stability. Utility Model Content

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 This utility model provides a technical solution for a sealed feeding structure for a calcined coke calcining furnace: It includes a feeding hopper 1, with a first support frame 2 connected to the inner wall of the feeding hopper 1. A spiral feeding rod 3 is rotatably connected to the first support frame 2 and the inner wall of the feeding hopper 1. A dust cover 4 is connected to the outer surface of the spiral feeding rod 3. A fixing plate 5 is connected to the outer surface of the feeding hopper 1. A first motor 6 is mounted on the upper surface of the fixing plate 5. The output end of the first motor 6 is connected to the left side of the spiral feeding rod 3. A dust pipe 7 is connected to the outer surface of the feeding hopper 1. The inner wall of pipe 7 is connected to a second support frame 8, and the upper surface of the second support frame 8 is connected to a smoke extraction fan 9. The end of dust pipe 7 away from the feed hopper 1 is connected to a flange 10. The flange 10 is a key connecting component in the dust treatment process of the sealed feeding structure of the calcined coke calciner. It provides a convenient and stable connection bridge between dust pipe 7 and external dust removal pipeline. Through the flange connection, the dust pipe 7 can be quickly connected to the external dust removal equipment, ensuring the sealing of the pipeline connection and preventing dust from leaking from the connection during the transportation process.

[0018] As shown in the figure, the outer surface of the feed barrel 1 is provided with a feed inlet 11. The inner wall of the feed inlet 11 has two sliding grooves 12. The two sliding grooves 12 are slidably connected to two cover plates 13. The cover plates 13 are important components to ensure the sealing of the sealed feed structure of the calcined coke calcining furnace. This closed state can effectively block the connection between the feed inlet 11 and the outside.

[0019] As shown in the figure, two connecting plates 14 are connected to the outer surface of the feed inlet 11, and each connecting plate 14 is connected to an electric telescopic rod 15 on its outer surface.

[0020] As shown in the figure, each electric telescopic rod 15 has a connecting frame 16 connected to its output end, and the two connecting plates 14 with their opposite sides connected to the outer surface of the connecting frame 16.

[0021] As shown in the figure, a bottom plate 17 is provided below the feeding barrel 1, and a calcining furnace body 18 is installed on the upper surface of the bottom plate 17. The upper surface of the calcining furnace body 18 is connected to the end of the feeding barrel 1 away from the first motor 6.

[0022] As shown in the figure, a bearing plate 19 is connected to the outer surface of the calcining furnace body 18, and a bearing frame 20 is connected to the upper surface of the bearing plate 19. The upper surface of the bearing frame 20 and the upper surface of the bottom plate 17 are connected to a transport frame 21. When the second motor 23 starts, under the stable support of the transport frame 21, the connecting shaft 24, belt 26, rotating rod 25 and grab plate 27 can cooperate in an orderly manner to smoothly complete the operation of conveying materials to the feed inlet 11, providing a stable material supply guarantee for the feeding process.

[0023] As shown in the figure, a mounting plate 22 is connected to the outer surface of the transport frame 21. A second motor 23 is mounted on the upper surface of the mounting plate 22. A connecting shaft 24 and a rotating rod 25 are rotatably connected inside the transport frame 21. A belt 26 is connected to the outer surface of the connecting shaft 24 and the outer surface of the rotating rod 25 for transmission. Several gripping plates 27 are mounted on the outer surface of the belt 26. The output end of the second motor 23 is connected to the right end of the connecting shaft 24.

[0024] As shown in the figure, a material collection frame 28 is installed on the upper surface of the base plate 17, and a control box 29 is installed on the outer surface of the material collection frame 28. In the material conveying process, when the belt 26 and the grab plate 27 complete the conveying operation of the material to the feed port 11, if there is a need for temporary storage of materials or adjustment of the feeding rhythm, the material collection frame 28 can collect the materials to be put in, so as to avoid the materials being piled up randomly, affecting the production environment or causing waste.

[0025] The working principle of this utility model is as follows: First, the flange 10 on the dust pipe 7 is connected to the external dust removal pipe. After completing the initial pipeline connection, the equipment is started through the control box 29 on the outer surface of the material collection frame 28 on the base plate 17. First, the control box 29 controls the electric telescopic rod 15 to work. The electric telescopic rod 15 extends and drives the connecting frame 16 to move, thereby causing the two cover plates 13 to slide to both sides along the sliding groove 12, opening the feed port 11. At the same time, the control box 29 starts the second motor 23. The second motor 23 drives the connecting shaft 24 to rotate. The connecting shaft 24 drives the rotating rod 25 to rotate synchronously through the belt 26. The gripper plate 27 on the outer surface of belt 26 moves with belt 26 to transport the material to feed inlet 11. The material enters feed hopper 1 through feed inlet 11. Then, control box 29 starts the first motor 6 on fixed plate 5. The output end of the first motor 6 drives the spiral feed rod 3 to rotate. The spiral feed rod 3 slowly transports the material in feed hopper 1 to calcining furnace body 18. During this process, control box 29 simultaneously starts the exhaust fan 9 in dust pipe 7. The exhaust fan 9 rotates to generate suction, which draws the dust generated in feed hopper 1 through dust pipe 7 and flange 10 to external dust removal pipe to prevent dust from entering calcining furnace body 18.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
