Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of expanded graphite, and particularly relates to an expansion furnace for processing expandable graphite. Background Art
[0002] Expanded graphite is a loose, porous, worm-like material made from natural graphite flakes through intercalation, washing, drying, and high-temperature expansion. In existing graphite expansion furnaces, graphite often accumulates before entering the heater. This large amount of graphite aggregates makes it difficult to heat the graphite inside the graphite block, thus affecting normal production efficiency.
[0003] The patent, CN216764342U, discloses an expansion furnace for processing expandable graphite. The furnace is equipped with a furnace body, a charging box, a heater, a telescopic rod, a tilting plate, a spring, a locking pin, a connecting rod, and a movable plate. During operation, the tilting plate is moved by the telescopic shaft of the telescopic rod. Once the tilting plate reaches the appropriate position, the shaft is retracted, and the spring's elastic action causes the tilting plate to swing, thereby preventing material from accumulating on the plate. Furthermore, before processing, the operator can adjust the angle of the two connecting rods using the locking pin, thereby adjusting the angle of the two movable plates and, consequently, the size of the blanking opening.
[0004] However, the graphite raw material easily accumulates and forms sticky lumps during transportation from the feed box to the furnace body. The above solution, which relies solely on the shaking of the tilting plate, cannot effectively disperse the sticky lumps. When the graphite raw material sticks to form sticky lumps, the graphite raw material inside the sticky lumps is not easily heated by the heater, resulting in low overall production efficiency and certain practical limitations.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.
[0023] like Figure 1-Figure 5 As shown, the technical solution adopted by the present invention is as follows: an expansion furnace for processing expandable graphite, comprising an expansion furnace 1, wherein a feed assembly is arranged at the top of the expansion furnace 1. The feed assembly comprises a stirring box 2, wherein the top of the expansion furnace 1 is connected to the stirring box 2, a feed port 201 is provided at the top of the stirring box 2, and a plug plate 202 is slidably inserted at the bottom of the stirring box 2. A stirring shaft is arranged horizontally in the stirring box 2, and both ends of the stirring shaft are rotatably connected to the inner wall of the stirring box 2. A first motor 3 is fixedly installed on the outer surface of the stirring box 2, and the output shaft of the first motor 3 is coaxially fixedly connected to one end of the stirring shaft. In addition, a plurality of stirring rods 203 are fixedly arranged on the outer surface of the stirring shaft, and the plurality of stirring rods 203 are staggered and distributed in a circular array along the central axis of the stirring shaft.
[0024] Graphite raw materials and additives are added to the mixing box 2 through the feed port 201. The first motor 3 is started, and the output shaft of the first motor 3 drives the stirring shaft to rotate. The stirring shaft drives the stirring rods 203 to rotate, thereby mixing the raw materials and additives in the mixing box 2. After mixing is completed, the operator pulls open the plug plate 202, connecting the mixing box 2 with the expansion furnace 1, and the materials fall into the expansion furnace 1.
[0025] Two inclined fixed plates 4 are symmetrically positioned on either side of the expansion furnace 1, tilted inward. Both fixed plates 4 are symmetrically positioned on the inner walls of the expansion furnace 1, with inclined plates 6 positioned to limit their sliding movement. Mounting boxes 12 are also fixedly mounted on these fixed plates 4. Mounting boxes 12 are located at the ends of the fixed plates 4 not connected to the expansion furnace 1, with a gap between them. The inclined plates 6 slide in the direction of the fixed plates 4's tilt. Protective plates are installed on both sides of each inclined plate 6 to prevent material from slipping out.
[0026] A screw rod 11 is rotatably provided in each installation box 12 , and both ends of each screw rod 11 are rotatably connected to the installation box 12 in which it is located. The number of screw rods 11 and inclined plates 6 is equal and corresponds one to one, and each screw rod 11 is in transmission cooperation with the corresponding inclined plate 6 .
[0027] The outer surface of each screw rod 11 is threadedly connected to a number of corrugated blocks 18. The corrugated blocks 18, screw rod 11 and balls form a ball screw pair. The corrugated blocks 18 are all in limited sliding cooperation with the installation box 12 in which they are located. The installation box 12 corresponds one-to-one with the inclined plate 6. Each installation box 12 is slidably penetrated by a number of slide bars 16 on the side facing the corresponding inclined plate 6. The slide bars 16 and the inclined plate 6 have the same sliding direction. The end of each slide bar 16 located outside the installation box 12 is fixedly connected to the corresponding inclined plate 6. The outer surface of each slide bar 16 is also covered with a spring 17. One end of the spring 17 is fixedly connected to the inclined plate 6, and the other end is fixedly connected to the installation box 12. In addition, the number of slide bars 16 and the corrugated blocks 18 is equal and corresponds one-to-one. The end of each slide bar 16 located inside the installation box 12 is in contact and sliding cooperation with the corrugated end of the corresponding corrugated block 18.
[0028] A second motor 13 is fixedly mounted on the outer surface of each mounting box 12. Each second motor 13 is coaxially fixedly connected to one end of the screw rod 11 within the corresponding mounting box 12. When the second motor 13 is activated, its output shaft drives the screw rod 11 to rotate. This rotation of the screw rod 11 causes a plurality of corrugated blocks 18 to slide along the central axis of the screw rod 11. During this sliding process, the corrugated blocks 18 come into contact with the slide rod 16. Due to the undulating shape of the corrugated ends of the corrugated blocks 18, upon contact, the corrugated blocks 18 drive the slide rod 16 to slide back and forth along its own central axis, thereby pushing the tilting plate 6 to slide synchronously back and forth on the surface of the fixed plate 4. This in turn shakes the material on the tilting plate 6 and prevents it from accumulating on the surface. Furthermore, during this process, the spring 17 repeatedly stretches and relaxes according to the undulations of the corrugated ends of the corrugated blocks 18, ensuring the normal sliding of the tilting plate 6.
[0029] In addition, a shaft rod 10 is rotatably provided at the bottom of each fixed plate 4 with an installation box 12 , both ends of the shaft rod 10 are rotatably connected to the fixed plate 4 , and a movable plate 5 is fixedly provided on the outer surface of each shaft rod 10 .
[0030] The shaft 10 is coupled to the screw 11. One end of the shaft 10 rotates and extends to the exterior of the fixed plate 4, where it is coaxially fixed with a first gear 14. The end of the screw 11 not connected to the output shaft of the second motor 13 is coaxially fixed with a second gear 15. The first gear 14 and the second gear 15 are meshed and always remain in meshing state.
[0031] The rotation of the screw 11 will drive the second gear 15 to rotate, and the rotation of the second gear 15 will drive the shaft 10 to rotate through the first gear 14, thereby driving the movable plate 5 to swing through the shaft 10. During the swinging process of the two movable plates 5, the materials between the two movable plates 5 will be impacted, making the materials between the two movable plates 5 more dispersed, thereby preventing the materials from sticking together to form adhesion blocks.
[0032] In addition, a collecting box 9 and a heat conducting plate 7 are fixedly installed in the expansion furnace 1, and a heater 8 is installed on the heat conducting plate 7. The collecting box 9 is located below the discharge port, and the heat conducting plate 7 is located between the discharge port and the collecting box 9.
[0033] The drawings in the specification of this solution are all structural schematic diagrams, and the specific sizes can be adjusted according to actual use.
[0034] Working Principle: During use, the operator adds graphite raw materials and additives into the mixing box 2 through the feed port 201, starts the first motor 3, and the output shaft of the first motor 3 drives the stirring shaft to rotate, which in turn drives the stirring rods 203 to rotate, thereby mixing the raw materials and additives in the mixing box 2. After mixing is completed, the operator pulls open the insert plate 202, connecting the mixing box 2 with the expansion furnace 1, and the materials will fall into the expansion furnace 1.
[0035] During the falling process, the heat conducting plate 7 transfers the heat generated by the heater 8, thereby expanding the material entering the expansion furnace 1. Most of the falling material will fall onto the inclined plate 6, and a small part of the material will fall directly into the collection box 9 after expansion.
[0036] Then, the two second motors 13 are started synchronously. The output shafts of the second motors 13 drive the screw rod 11 to rotate. The rotation of the screw rod 11 drives several corrugated blocks 18 to slide along the central axis of the screw rod 11. The corrugated blocks 18 will contact the sliding rod 16 during the sliding process.
[0037] As the slide bar 16 slides from the concave point of the corrugated block 18 to the convex point of the corrugated block 18, the corrugated block 18 pushes the inclined plate 6 upward along the fixed plate 4 through the slide bar 16, at which time the spring 17 is stretched. As the slide bar 16 slides from the convex point of the corrugated block 18 to the concave point of the corrugated block 18, the spring 17 gradually recovers, and the inclined plate 6 moves downward under the action of gravity and the elasticity of the spring 17, thereby achieving the purpose of shaking the inclined plate 6 and preventing material from accumulating on the surface of the inclined plate 6.
[0038] At the same time, the rotation of the screw rod 11 drives the second gear 15 to rotate, and the rotation of the second gear 15 drives the shaft rod 10 to rotate through the first gear 14, thereby driving the two movable plates 5 to swing through the two shaft rods 10. The swinging process of the two movable plates 5 can impact the material between the two movable plates 5, making the material between the two movable plates 5 more dispersed, thereby preventing the material from sticking together to form a sticky block, and avoiding the problem that the material inside the sticky block cannot effectively contact the heat conducting plate 7 when the sticky block passes through the heat conducting plate 7.
[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
