Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a horizontal reaction vessel. Background Technology

[0002] In traditional graphite anode experiments and production processes, artificial graphite precursors require secondary granulation to meet specific production needs. However, while existing large-scale horizontal heated reactors are suitable for mass production, their large size makes them unsuitable for experimental small-scale material verification.

[0003] In the design of horizontal heating reactors, the discharge port typically has a slight indentation. During the miniaturization process, existing equipment is only reduced in size to ensure equipment and production safety, without any structural changes. However, large equipment usually relies on an external vacuum system to achieve smooth material discharge and continuous operation under negative pressure and the weight of the material itself. Miniaturized horizontal reactors, often used for single-use experiments, lack a vacuum system and the impact force of batch materials. The uniformly mixed graphite material, under the influence of volatiles, easily forms slight agglomerates at the discharge port indentation. These agglomerates cannot be effectively broken up by the existing stirring system, leading to material blockage. This results in frequent material blockage problems in small horizontal heating reactors, affecting production efficiency. Utility Model Content

[0004] The main purpose of this invention is to propose a horizontal reactor to solve the problem of material blockage at the discharge point of a small heating reactor.

[0032] In traditional graphite anode experiments and production processes, artificial graphite precursors require secondary granulation to meet specific production needs. However, while existing large-scale horizontal heated reactors are suitable for mass production, their large size makes them unsuitable for experimental small-scale material verification.

[0033] In the design of horizontal heating reactors, a small indentation is typically present at the discharge port. This indentation is formed by a drop of approximately 1-2 cm between the top of the discharge valve and the bottom of the reactor body. In the miniaturization process, existing technologies prioritize equipment and production safety, miniaturizing the structure of all equipment without altering its features. However, large equipment typically relies on an external vacuum system to achieve smooth material discharge and continuous operation under negative pressure and the weight of the material itself. Miniaturized horizontal reactors, often used for single-use experiments, lack a vacuum system and the impact force of batch materials. The uniformly mixed graphite material, under the influence of volatiles, easily forms slight agglomerates at the discharge port indentation. These agglomerates cannot be effectively broken up by existing stirring systems, leading to material blockage. This results in frequent material blockage issues in small horizontal heating reactors, impacting production efficiency.

[0034] This utility model proposes a horizontal reaction vessel 100.

[0035] Please see Figures 1 to 3 In one embodiment of this utility model, the horizontal reactor 100 includes:

[0036] 1. Pot body;

[0037] The discharge section 2 is fixedly connected to the vessel body 1. The discharge section 2 is provided with an inlet port 21, and the inlet port 21 protrudes from the inner wall of the vessel body 1.

[0038] A stirring device 3 is rotatably connected inside the vessel body 1, and a relief part 31 is formed inward at the location corresponding to the feed port 21.

[0039] It should be noted that the horizontal reactor 100 also includes a transmission mechanism, which drives the stirring device 3 to rotate. Optionally, the transmission mechanism is a motor. By adjusting the frequency of the motor, the linear speed of the stirring device 3 can be adjusted. The centrifugal force generated by the stirring device 3 causes the material to rotate continuously along the cylinder wall and fall continuously. After the heat preservation is completed, the material is discharged from the inside of the reactor body 1 through the discharge part 2.

[0040] It should be noted that the discharge section 2 is tightly fitted to the vessel body 1 to ensure the airtightness of the vessel body 1.

[0041] The technical solution of this utility model reduces or eliminates the height difference between the discharge section 2 and the vessel body 1 through the avoidance part 31, while ensuring that the stirring device 3 will not collide with the discharge section 2 during rotation, thus protecting the safe operation of the equipment. The discharge section 2 is provided with a feeding port 21, which protrudes from the inner wall of the vessel body 1 to avoid indentation. The material is discharged from the feeding port 21 without relying on an external vacuum system, which can realize the smooth discharge of the material, reducing equipment and maintenance costs, saving space, and ensuring the continuity and stability of production by avoiding the problem of material blockage, thereby improving production efficiency.

[0042] Optionally, there is a gap between the avoidance part 31 and the discharge part 2 to prevent the stirring device 3 from colliding with the discharge part 2 when it is rotating and stirring, so as to ensure the safe operation of the equipment.

[0043] Optionally, the clearance portion 31 includes two semi-convex spiral ribbons 311, which are connected to each other, and a recess 312 is formed between the two semi-convex spiral ribbons 311. The recess 312 is adapted to the discharge portion 2 and there is a gap between it and the discharge portion 2.

[0044] It is understood that the recess 312 formed between the two semi-convex spiral ribbons 311 corresponds to the discharge part 2. This design ensures that the stirring device 3 can accurately avoid the discharge part 2 during rotation, thereby avoiding direct collision between the stirring device 3 and the discharge part 2 and ensuring the safe operation of the equipment.

[0045] Furthermore, the two semi-convex spiral ribbons 311 enable the stirring device 3 to further increase the area of ​​the stirred material when rotating, especially the material near the discharge section 2, so as to avoid the material from clumping in the discharge section 2 and causing blockage of the discharge section 2, which helps to maintain the continuity of material flow and improve production efficiency.

[0046] In one embodiment, there is a gap of 1-2 cm between the recess 312 and the discharge part 2 to prevent the stirring device 3 from directly colliding with the discharge part 2.

[0047] Optionally, the discharge section 2 further includes an anti-caking protrusion 22, which is connected to the inner wall of the vessel body 1 and protrudes into the vessel body 1. The inlet port 21 is located on the anti-caking protrusion 22. The anti-caking protrusion 22 corresponds to the recess 312, and there is a gap between the anti-caking protrusion 22 and the clearance section 31.

[0048] It should be noted that the anti-caking protrusion 22 is connected to the inner wall of the vessel body 1 and protrudes into the vessel body 1, which changes the flow state of the material in the discharge area, reduces the residence time and accumulation opportunity of the material in the area, thereby effectively preventing the material from forming clumps in the discharge section 2 and ensuring the smoothness of discharge.

[0049] It should be noted that the anti-caking protrusion 22 protrudes into the interior of the vessel body 1. To prevent the stirring device 3 from colliding with the anti-caking protrusion 22, the recess 312 can effectively avoid the anti-caking protrusion 22. There is a gap between the two, which ensures the safe operation of the equipment.

[0050] In some embodiments, the side of the anti-caking protrusion 22 is arc-shaped. The arc-shaped side makes the transition between the anti-caking protrusion 22 and the inner wall of the vessel body 1 smoother, reducing the resistance and friction of the material during the flow process, and helping the material to flow more smoothly along the anti-caking protrusion 22, avoiding material accumulation and blockage problems.

[0051] Optionally, a discharge channel 23 is provided through the discharge section 2, which passes through the vessel body 1 and the anti-caking protrusion 22, and one end is connected to the inlet port 21.

[0052] like Figure 2 As shown, it can be understood that the material can enter the discharge channel 23 through the feed port 21 and be discharged from the inside of the vessel body 1. The anti-caking protrusion 22 can effectively prevent the material from accumulating at the feed port 21 and ensure smooth discharge from the discharge channel 23.

[0053] Optionally, the anti-knotting protrusion 22 is spaced 1-2 cm apart from the avoidance portion 31.

[0054] It should be noted that when the gap between the anti-caking protrusion 22 and the avoidance part 31 is too large, the stirring dead angle of the stirring device 3 will increase, and it will be unable to effectively crush the material near the discharge part 2.

[0055] When the gap between the anti-caking protrusion 22 and the avoidance part 31 is too small, it may cause the stirring device 3 to collide with the discharge part 2. This requires high assembly accuracy between the two. The small gap places extremely high demands on the assembly accuracy, increasing the difficulty and cost of manufacturing and installation. Therefore, the interval between the anti-caking protrusion 22 and the avoidance part 31 is preferably 1-2 cm.

[0056] Optionally, the discharge section 2 includes a valve body 24 and a valve cover 25. The valve body 24 and the valve cover 25 are both fixedly connected to the vessel body 1. The valve cover 25 is located inside the vessel body 1, and the valve body 24 is located outside the vessel body 1. The valve cover 25 is provided with a discharge channel 23, which passes through the vessel body 1 and communicates with the valve body 24.

[0057] In some embodiments, the discharge channel 23 is arranged perpendicular to the inner wall of the vessel body 1 and is tangent to the anti-caking protrusion 22.

[0058] The discharge channel 23 is provided with the inlet port 21, and the inlet port 21 protrudes from the inner wall of the vessel body 1.

[0059] It should be noted that the valve cover 25 can prevent the formation of a recess in the discharge part 2, and the combination of the valve body 24 and the valve cover 25 can effectively clamp the vessel body 1, thereby enhancing the sealing performance of the vessel body 1.

[0060] Optionally, the valve body 24 and the valve cover 25 can be fixed relative to the vessel body 1 by means of bolt connection or welding, and this embodiment does not impose specific restrictions on this.

[0061] In some embodiments, the anti-caking protrusion 22 is provided on the valve cover 25 and is disposed opposite to the feed port 21.

[0062] Optionally, the stirring device 3 includes a rotating shaft 32 and a spiral stirrer 33, the spiral stirrer 33 is provided with the clearance part 31, and the rotating shaft 32 is rotatably connected to the vessel body 1 along the axial direction of the vessel body 1;

[0063] The spiral stirrer 33 is arranged around the rotating shaft 32 and is fixedly connected to the rotating shaft 32.

[0064] It should be noted that the output end of the transmission mechanism is connected to the rotating shaft 32 to drive the rotation of the rotating shaft 32, while the spiral stirrer 33 is fixedly connected to the rotating shaft 32. When the rotating shaft 32 rotates, the spiral stirrer 33 rotates around the rotating shaft 32 to stir the material in the vessel 1.

[0065] The rotating shaft 32 is rotatably connected to the vessel body 1 along the axial direction of the vessel body 1, which increases the stirring area of ​​the spiral agitator 33, so that the material is more fully and evenly stirred in the vessel body 1. In addition, the avoidance part 31 avoids the discharge part 2, ensuring the safe operation of the equipment and protecting the stirring device 3 from collision damage from the discharge part 2.

[0066] Optionally, the rotating shaft 32 is provided with a plurality of fixed rods spaced apart along the axial direction. One end of each fixed rod is fixedly connected to the rotating shaft 32, and the other end is fixedly connected to the spiral stirrer 33.

[0067] It should be noted that the multiple fixing rods are spaced apart along the axial direction of the rotating shaft 32, which not only provides additional support points for the spiral stirrer 33, but also significantly enhances the structural stability and rigidity of the entire stirring device 3. This design makes the stirring device 3 more stable when rotating at high speed, reduces equipment wear and noise caused by vibration and shaking, and extends the service life of the equipment;

[0068] Furthermore, the presence of the fixing rod makes the connection between the rotating shaft 32 and the spiral agitator 33 tighter and the energy transfer more efficient. This helps to more fully transmit the rotational power of the rotating shaft 32 to the spiral agitator 33, allowing the material to be more fully and evenly stirred within the vessel 1. Simultaneously, the fixing rod also provides a certain degree of crushing and shearing action, helping to break up agglomerates in the material and further improving the stirring effect.

[0069] Optionally, there are two spiral stirrers 33, which are symmetrically arranged relative to the rotating shaft 32.

[0070] It should be noted that the two spiral stirrers 33 enable more uniform and smooth stirring within the vessel 1. This design not only accelerates the stirring efficiency of the materials but also significantly improves the uniformity of stirring, ensuring that the materials are fully stirred and reacted within the vessel 1.

[0071] The two spiral stirrers 33 are symmetrically arranged relative to the rotating shaft 32. The two symmetrically arranged spiral stirrers 33 can better balance the load on the rotating shaft 32, making energy transfer more uniform and efficient, which helps to reduce the energy consumption of the equipment and improve energy utilization efficiency. In addition, the symmetrical arrangement of the two spiral stirrers 33 helps to reduce the vibration and shaking of the equipment during operation, thereby improving the reliability and stability of the equipment.

[0072] It should be noted that the spiral mixer 33 includes a first stirring ribbon 331, which is connected to the rotating shaft 32 and is located on one side of the discharge section 2 to push the material to move towards the discharge section 2.

[0073] The portion of the first stirring screw 331 near the side wall of the vessel body 1 is adapted to the shape of the inner side wall of the vessel body 1.

[0074] It should be noted that the first stirring screw 331 is located on one side of the discharge section 2. Through the extrusion force generated by the rotation, it can effectively push the material towards the discharge section 2. It can be understood that when the discharge section 2 is opened, the first stirring screw 331 can push the material in the vessel 1 towards the discharge section 2. As the material continuously rotates along the inner wall of the vessel 1, the material continuously descends from the discharge section 2, which facilitates the discharge of the material inside the vessel 1 and improves the material discharge efficiency.

[0075] In some embodiments, there are two first stirring screws 331, which are located on both sides of the discharge section 2. Optionally, the two first stirring screws 331 are symmetrically arranged relative to the discharge section 2.

[0076] like Figure 1 As shown, it can be understood that the matching shape of the first stirring screw ribbon 331 and the inner wall of the valve body 24 ensures that the material is in full contact with the first stirring screw ribbon 331 during the stirring process, reduces the stirring dead angle, and makes the material more uniformly mixed in the vessel body 1, thereby improving the stirring efficiency.

[0077] It should be noted that the cross-sections of the two side walls of the vessel body 1 are usually arc-shaped. Therefore, in order to increase the stirring area, the shape of the first stirring ribbon 331 can be adapted to the side wall of the vessel body 1 and is also arc-shaped to increase the stirring area.

[0078] Optionally, the spiral mixer 33 further includes a second stirring ribbon 332, which is connected to the rotating shaft 32 and is correspondingly arranged with the discharge part 2. The second stirring ribbon 332 is provided with the avoidance part 31, and the first stirring ribbon 331 is located on one side of the second stirring ribbon 332.

[0079] The maximum rotation diameter of the first stirring ribbon 331 around the rotating shaft 32 is greater than the maximum rotation diameter of the second stirring ribbon 332 around the rotating shaft 32.

[0080] It should be noted that the first stirring screw ribbon 331 is located on one side of the second stirring screw ribbon 332, and the maximum rotation diameter of the first stirring screw ribbon 331 around the rotating shaft 32 is larger than that of the second stirring screw ribbon 332. Since the default state of the equipment is clockwise rotation, the material always moves in one direction. During the stirring process, it is pushed towards the second stirring screw ribbon 332 by the first stirring screw ribbons 331 on both sides. The avoidance part 31 formed by the second stirring screw ribbon 332 is correspondingly arranged with the discharge part 2. During stirring, the avoidance part 31 further disperses the material, causing it to move to both sides. Simultaneously, the avoidance part 31 ensures that the stirring process will not collide with the discharge part 2. Finally, under the action of the first stirring screw ribbon 331 and the second stirring screw ribbon 332, the material is evenly discharged from the discharge part 2, improving the material discharge efficiency.

[0081] Optionally, the valve body 24 further includes a valve core 26, which is used to control the opening and closing of the discharge channel 23.

[0082] like Figure 3 As shown, in some embodiments, the discharge section 2 includes a valve body 24 and a valve core 26. The valve core 26 is movably connected to the valve body 24 and partially protrudes from the inner surface of the reactor body 1 to form the inlet port 21.

[0083] In some implementations, such as Figure 3 As shown, the valve core 26 has a discharge channel 23 inside. The valve core 26 is rotatably connected to the valve body 24 to control the opening and closing of the discharge section 2. When the valve core 26 rotates to a certain angle, the discharge channel 23 connects to the inside of the vessel body 1 for material discharge. When the valve core 26 rotates to another angle, it drives the discharge channel 23 to rotate, and the discharge channel 23 is blocked by the valve body 24 to prevent material discharge and ensure the sealing of the inside of the vessel body 1. The valve core 26 is tangent to the valve body 24 to ensure sealing. The valve core 26 provides an arc-shaped surface for the avoidance part 31 of the vessel body 1 to protect the stirring device 3 from collision damage from the discharge section 2.

[0084] It should be noted that the discharge section 2 includes a discharge valve, which includes the valve body 24 and the valve cover 25. The valve core 26 is located inside the vessel body 1 and forms the anti-caking protrusion 22. The anti-caking protrusion 22 is the upper half-arc surface of the valve core 26 protruding from the inner wall of the vessel body 1. Therefore, there is no gap between the valve core 26 and the vessel body 1 due to the height difference. When the valve core 26 moves open, the material between the anti-caking protrusion 22 and the clearance part 31 will fall out due to the pushing of the other materials and its own weight, reducing the risk of material blockage.

[0085] In another embodiment, there is a gap between the discharge valve and the valve core 26 on the side of the valve body 24 that is close to the inside of the valve. Material will accumulate in the gap, but when the valve core 26 moves to open, the material accumulated in the gap will fall out due to the compression of the other materials and its own weight, reducing the risk of material blockage.

[0086] In some embodiments, the discharge section 2 is a high-temperature resistant ball valve. The upper hemispherical part of the high-temperature ball valve is located inside the vessel body 1. When the high-temperature ball valve is opened, the spherical part will rotate to the outside of the vessel body 1 to ensure the unobstructed flow of the discharge channel 23. The high-temperature ball valve protrudes 1-2cm from the inner wall of the vessel body 1, and there is a 1-2cm gap between the high-temperature resistant ball valve and the recess 312 of the clearance part 31.

[0087] It should be noted that, due to the change in the position of the high-temperature ball valve, the valve stem of the high-temperature ball valve needs to be lengthened to ensure that the control end of the high-temperature ball valve is still located outside the valve body 24.

[0088] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
