Description

Technical Field

[0001] This invention belongs to the field of graphite preparation technology: specifically, it relates to a reaction vessel for graphite preparation. Background Technology

[0002] A reaction vessel for graphite preparation is a container used to carry out chemical reactions related to graphite preparation. Through structural design and parameter configuration of the container, the heating, evaporation, cooling and mixing functions required by the process can be realized to meet the specific needs of the graphite preparation process. During the reaction, graphite ore is added to the reactor, and the heat required for the reaction is provided by a heating device to cause the reactants to undergo a chemical reaction and generate the desired product. At the same time, the stirrer continuously stirs the reactants to ensure that the reaction proceeds uniformly.

[0003] In the prior art, when graphite raw materials of different particle sizes are reacted at high temperatures in a reactor, the raw materials with smaller particle sizes are prone to overheating, while the raw materials with larger particle sizes have limited contact with the heat source. Under the same reaction conditions, the heat absorbed is far from sufficient. Insufficient heat makes it difficult for large graphite particles to reach the temperature required for the reaction, which affects the consistency of the reaction.

[0011] Preferably, the screening component includes two feeding plates, which are inclined and symmetrical. Both feeding plates are located above preparation tank one and preparation tank two. The surface of the feeding plates is provided with several feeding holes one and two, the diameter of feeding hole two is larger than the diameter of feeding hole one, and a vibration component is provided on one side of each feeding plate.

[0012] Preferably, the vibration assembly includes two connecting rods, each fixedly connected to one end of the feeding plate. Both ends of the connecting rods are fixedly connected to pulleys.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 9 As shown, the present invention provides a technical solution: a reaction vessel for graphite preparation, including a reaction vessel 1, a feeding bin 2 at the top of the reaction vessel 1, a feeding pipe 3 symmetrically and fixedly connected to the bottom of the feeding bin 2, heating bins 4 fixedly installed on both sides of the bottom of the reaction vessel 1, the ends of the two feeding pipes 3 away from the feeding bin 2 being located inside the reaction vessel 1, preparation tank 1 5 and preparation tank 2 6 respectively arranged inside the reaction vessel 1, preparation tank 1 5 being located directly above preparation tank 2 6, and the lateral length of preparation tank 2 6 being greater than the lateral length of preparation tank 1 5, a feeding port 7 being opened at the top of preparation tank 1 5 and preparation tank 2 6, a drive component for driving the rotation of preparation tank 1 5 and preparation tank 2 6 being arranged on one side, a stirring component being arranged inside preparation tank 1 5 and preparation tank 2 6, and a screening component for screening graphite ore raw materials being arranged above preparation tank 1 5 and preparation tank 2 6.

[0023] During operation: Crushed and purified graphite ore is continuously fed into the feed hopper 2. The raw material then enters the reactor 1 through the feed pipe 3. After entering the reactor 1, the raw material first falls into the screening component, which sorts it according to size. Smaller raw materials fall into preparation tank 5, while larger raw materials fall into preparation tank 6. After the raw materials are added, a heat source is placed in the heating chamber 4. Hot air flows upward from the bottom of the reactor 1, forming a gradient temperature field, which gradually increases the temperature inside the reactor. Because preparation tank 6 is closer to the heating chamber 4, the larger particles inside absorb more heat, allowing for a more thorough high-temperature reaction under sufficient heat supply. Preparation tank 5 is slightly farther from the heating chamber 4, and the smaller particles inside absorb relatively less heat, effectively avoiding the negative effects of overheating. Furthermore, the raw materials undergo high-temperature reactions in different areas inside the reactor 1. In response, the drive component will cause preparation tank 5 and preparation tank 6 to rotate. The rotation will allow the raw materials to come into full contact with heat, achieving uniform heating. During the rotation of preparation tank 5 and preparation tank 6, the stirring component will also rotate synchronously. The rotation of preparation tank 5 and preparation tank 6 will allow the raw materials inside the tanks to continuously tumble and move, avoiding uneven heating caused by prolonged stillness. Whether it is the raw material with smaller particle size in preparation tank 5 or the raw material with larger particle size in preparation tank 6, it can come into full contact with heat during the rotation, achieving uniform heating and improving the efficiency and consistency of the reaction. The rotation of the stirring component will provide more detailed and in-depth stirring of the raw materials, making the raw materials evenly distributed inside preparation tank 5 and preparation tank 6, breaking the possible local accumulation or stratification of raw materials, and allowing each raw material particle to move freely and be fully dispersed inside preparation tank 5 and preparation tank 6. Through the above embodiments, the screening component enables larger particle size raw materials to absorb more intense heat from the heating chamber 4 in preparation tank 2 6 for high-temperature reaction, while smaller particle size raw materials in preparation tank 1 5 are prevented from being overheated, thereby optimizing the entire reaction process and improving product quality; through the drive component and stirring component, the raw materials are made into full contact with heat, achieving uniform heating and improving the efficiency and consistency of the reaction.

[0024] like Figures 2 to 3 As shown, the drive assembly includes a servo motor 12. Side plates 8 are fixedly connected to both sides of preparation tank 1 5 and preparation tank 2 6. Rotating rods 9 are fixedly connected to both sides of the side plates 8. The rotating rods 9 are rotatably connected to the inner wall of the reactor 1. A transmission ring 10 is fixedly connected to one end of each of the two rotating rods 9. A transmission belt 11 is connected between the outer walls of the two transmission rings 10. The output shaft of the servo motor 12 is fixedly connected to one end of one of the rotating rods 9.

[0025] During operation: When the servo motor 12 is started, its output shaft will drive one of the rotating rods 9 to rotate, and through the transmission relationship between the transmission ring 10 and the transmission belt 11, it will drive the other rotating rod 9 to rotate. When the two rotating rods 9 are rotating, they will drive the preparation tank 1 5 and the preparation tank 2 6 to rotate through the side plate 8 respectively. When the preparation tank 1 5 and the preparation tank 2 6 are rotating, the raw materials inside can fully contact the heat, thereby achieving a uniform heating effect.

[0026] like Figures 4 to 5 As shown, the stirring assembly includes multiple internal gear disks 13, which are rotatably connected to one side of multiple side plates 8. A stirring rod 15 is symmetrically rotatably connected between each pair of side plates 8. Gears 14 are fixedly connected to both ends of the stirring rod 15. The teeth of the gears 14 mesh with the teeth of the internal gear disks 13. Several sets of stirring blades 16 are fixedly connected to the outer walls of the two stirring rods 15. Each set of stirring blades 16 is arranged alternately with each other.

[0027] During operation: When the drive assembly drives the side plate 8 to rotate, the inner gear disk 13 is rotatably connected to the side plate 8. At this time, the inner gear disk 13 does not rotate, while the gear 14 and the stirring rod 15 revolve around the center point of the side plate 8. During the revolve of the gear 14 and the stirring rod 15, under the meshing action of the inner gear disk 13 and the gear 14, the two stirring rods 15 will also rotate on their own axis. This allows each stirring blade 16 to evenly distribute the raw materials entering the preparation tank 5 and the preparation tank 6, avoiding local accumulation or stratification of the raw materials and further improving the heating effect of the raw materials.

[0028] like Figure 3 and Figure 6 As shown, the outer walls of preparation tank 1 5 and preparation tank 2 6 are rotatably connected to a limiting shell 17. The limiting shell 17 is similar in shape to preparation tank 1 5 and preparation tank 2 6. An expansion plate 18 is fixedly connected to the top of the limiting shell 17.

[0029] During operation: The limiting shell 17 effectively prevents raw materials from falling out of the inlet 7 during the rotation of preparation tank 5 and preparation tank 6, ensuring the stability of the raw materials in the preparation tank and the continuity of the preparation process. The expansion plate 18 increases the area of ​​raw materials entering the preparation tank 5 and preparation tank 6, reducing the leakage of raw materials due to the small space and improving the efficiency and accuracy of feeding.

[0030] like Figure 6As shown, a fixing rod 19 is fixedly connected to one side of the limiting shell 17, and an inner slider 20 is fixedly connected to one end of the fixing rod 19. Two circular rings 21 are fixedly connected to the inner wall of the reactor 1. The inner slider 20 is slidably connected to the circular rings 21. Two telescopic rods 22 are fixedly connected to the side of the reactor 1. One end of the telescopic rod 22 is in contact with the side of the inner slider 20.

[0031] During operation: As the reaction proceeds with the rotation of preparation tank 5 and preparation tank 6, the limiting shell 17 and the expansion plate 18 cannot rotate because the inner slider 20 is blocked by the telescopic rod 22, thus effectively surrounding and blocking the feed inlet 7. At this time, the limiting shell 17 and the expansion plate 18 prevent the raw materials from leaking out. After the raw materials complete the high-temperature reaction, the feed inlet 7 rotates to its initial position and faces directly upward. At this time, the telescopic rod 22 is controlled to retract, so that one end no longer adheres to the side of the inner slider 20. The rotation of preparation tank 5 and preparation tank 6 continues, which will drive the limiting shell 17 and the expansion plate 18 to rotate together. The inner slider 20 rotates along the inner wall of the circular ring 21. When the feed inlet 7 and the expansion plate 18 rotate 180 degrees, both the feed inlet 7 and the expansion plate 18 face directly downward, and the raw materials inside preparation tank 5 and preparation tank 6 will automatically fall out, thereby achieving the discharge of the raw materials.

[0032] like Figures 7 to 9 As shown, the screening component includes two feeding plates 25, which are inclined and symmetrical. Both feeding plates 25 are located above preparation tank 1 5 and preparation tank 2 6. The surface of the feeding plates 25 is provided with several feeding holes 1 26 and feeding holes 27. The diameter of feeding hole 27 is larger than that of feeding hole 1 26. A vibration component is provided on one side of each feeding plate 25.

[0033] During operation: When the raw material falls from the outlet of the feed pipe 3 to the top of the inclined surface of the two feed plates 25, the raw material will be diverted: the smaller raw material will pass through the feed hole 1 26 and fall into the preparation tank 1 5; the larger raw material will continue to flow along the inclined surface of the feed plate 25 and then fall from the feed hole 27 into the preparation tank 2 6. During this process, the vibration component causes the feed plate 25 to vibrate to prevent the raw material from accumulating and blocking the feed hole 1 26 and the feed hole 27.

[0034] like Figures 7 to 9 As shown, the vibration assembly includes two connecting rods 28, which are fixedly connected to one end of the feeding plate 25. Both ends of the connecting rods 28 are fixedly connected to pulleys 30. An electric slide rail 34 is symmetrically fixedly connected to one side of the reactor 1. An electric slider 33 is symmetrically slidably connected to the inner wall of the electric slide rail 34. A triangular truncated pyramid 31 is fixedly connected to the top of each electric slider 33. A groove 32 is opened on the inclined surface of the triangular truncated pyramid 31. The groove 32 and the pulley 30 are slidably connected and adapted to each other.

[0035] During operation: Current is supplied to the two electric slide rails 34, controlling the electric slider 33 to slide back and forth inside the electric slide rails 34. The back and forth sliding of the electric slider 33 will drive the triangular table 31 to move back and forth as well. The movement of the triangular table 31 will cause the pulley 30 to slide repeatedly along the slide groove 32. During the repeated sliding of the pulley 30, the connecting rod 28 will move up and down, thereby causing the bottom of the feeding plate 25 to vibrate continuously. The raw materials can be screened and fed quickly and accurately, reducing the production downtime caused by raw material blockage or inaccurate diversion, thereby improving the efficiency of the entire production process.

[0036] like Figure 7 and Figure 9 As shown, movable blocks 29 are symmetrically fixedly connected to the outer walls of the two connecting rods 28. The movable blocks 29 are slidably connected to the side wall grooves of the reactor 1. Extrusion rods 35 are symmetrically fixedly connected to the side wall grooves of the reactor 1. The extrusion rods 35 are fixedly connected to the movable blocks 29.

[0037] During operation: When one end of the feeding plate 25 moves up and down, the moving block 29 moves repeatedly along the side wall groove of the reactor 1. Since the moving direction of one end of the feeding plate 25 is always straight up and down, the second feeding hole 27 and the first feeding hole 26 are always accurately positioned above the first preparation tank 5 and the second preparation tank 6 throughout the process, ensuring that the raw materials can fall into the corresponding preparation tanks accurately. In addition, through the extrusion rod 35, when the moving block 29 moves, it will repeatedly extrude the extrusion rod 35, and the extrusion rod 35 always acts as a shield against the side wall groove of the reactor 1, which can effectively prevent the loss of heat.

[0038] like Figures 7 to 8 As shown, a horizontal plate 39 is fixedly connected to the inner wall of the reactor 1. Compression springs 38 are fixedly connected to both sides of the horizontal plate 39. A hinge seat 37 is fixedly connected to one end of each compression spring 38. A hinge member 36 is hinged to the inner wall of each hinge seat 37. The hinge member 36 is fixedly connected to the top of the feed plate 25.

[0039] During operation: When the bottom end of the feeding plate 25 moves up and down, the top of the feeding plate 25 will hinge and rotate with the hinge seat 37, which improves the stability of the feeding plate 25 during vibration. Since the bottom end of the feeding plate 25 moves in a straight line when moving up and down, the elastic force of the compression spring 38 can balance the various external forces that the feeding plate 25 is subjected to during the up and down movement, making the movement of the feeding plate 25 more stable. It can reduce the shaking and deviation of the feeding plate 25 during the movement, and ensure that the feeding plate 25 moves up and down according to the predetermined trajectory, thereby improving the accuracy and stability of feeding.

[0040] like Figures 1 to 2As shown, the bottom of the reactor 1 is fixedly connected to a discharge pipe 24, and a valve 23 is installed on the outside of the discharge pipe 24.

[0041] During operation: After the raw materials fall out from preparation tank 1 5 and preparation tank 2 6, valve 23 is opened, and the raw materials can fall out through discharge pipe 24, thereby separating and collecting the prepared graphite from the inside of reactor 1.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
