A shipboard constant power supply continuous graphitization system and operation method

Abstract

The application discloses a ship-mounted constant-power power supply continuous graphitization system and a running method. The system comprises a ring-shaped moving mechanism, a clamping mechanism and a transformer. The ring-shaped moving mechanism comprises a ring-shaped water tank and a plurality of moving ships. The clamping mechanism comprises a plurality of clamps. The output end of the transformer is electrically connected with each clamp. The application has the advantages that each graphitization furnace is sequentially driven by the ring-shaped moving mechanism to pass through each heating area. The target heating temperature of each heating area is different. When the graphitization furnace sequentially passes through each heating area, the temperature gradually increases. The heating power of the heating area with a high target heating temperature is high, and the heating power of the heating area with a low target heating temperature is low. However, the transformer simultaneously supplies power to the clamps of all the heating areas. Therefore, after the system is stably operated, the total heating power can be kept substantially stable, so that the power demand in the heating process is more stable, the power utilization rate of the transformer is improved, and the production cost is reduced.

Description

Technical Field

[0001] This invention relates to the field of graphitization technology, specifically to a shipborne constant power continuous graphitization system and its operation method. Background Technology

[0002] Graphitization refers to the process by which non-graphitic carbon, under high-temperature conditions (usually exceeding 2000℃) in a protective medium within a high-temperature electric furnace, transforms its amorphous, disordered layered structure into three-dimensional ordered graphite crystals. This process primarily relies on physical changes, where heating allows the hexagonal carbon atom planar network layer stacking structure to develop and mature, forming the three-dimensional ordered structure of graphite.

[0003] Graphitization technology has wide applications in various fields, including: Lithium-ion batteries: Graphitization is a key process in the production of artificial graphite anodes, improving the energy density and cycle stability of the anode material. Metallurgical industry: Graphitized carbon materials can be used to manufacture blast furnace electrodes, electrolytic aluminum electrodes, etc., to improve their high-temperature resistance, oxidation resistance, and conductivity. Wear-resistant and lubricating materials: Graphitized carbon materials have good lubricity and wear resistance, and can be used to manufacture wear-resistant and lubricating parts such as bearings and seals. Refractory materials: Graphitized carbon materials can be used as raw materials for refractory bricks, metallurgical crucibles, etc., to improve their high-temperature resistance.

[0004] Graphitization furnaces typically employ resistance heating. A resistance material is filled inside the furnace, and when electricity is applied, it heats up, thus heating the target material within the furnace. Because the resistivity of the resistance material decreases with increasing temperature, its temperature rises continuously during the heating process, leading to a gradual decrease in resistivity and consequently, a gradual increase in heating power. This results in a lower load on the power supply transformer during the initial heating phase and a higher load during the later stages, necessitating the purchase of a high-power transformer. Furthermore, the transformer's power utilization is low during the initial heating phase, increasing production costs. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a shipborne constant power supply continuous graphitization system and operation method. This invention solves the technical problem that in the prior art, the transformer supplying power to the graphitization furnace has a low load in the early stage of heating and a very high load in the later stage of heating. Therefore, it is necessary to purchase a high-power transformer for power supply, and the power utilization rate of the transformer is not high in the early stage of heating, which increases the production cost.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This invention provides a shipborne constant power supply continuous graphitization system, comprising:

[0023] The present invention also provides an operation method for a shipborne constant power supply continuous graphitization system, applicable to the aforementioned shipborne constant power supply continuous graphitization system, and includes the following steps:

[0024] S1. Each mobile boat moves on the annular water tank, thereby driving the graphitization furnace to pass through the charging station, heating station, cooling station and unloading station in sequence. Each mobile boat stops once after moving one unit length, and the unit length is the distance between the midpoints of two adjacent mobile boats.

[0026] S3. The heating station is divided into several heating zones, each with a preset target heating temperature. The target heating temperature of each heating zone increases sequentially along the direction of movement of the mobile boat. Each heating zone is equipped with a clamp. When any graphitization furnace moves to a certain heating zone, the clamp of that heating zone is electrically connected to the connector of the graphitization furnace. The temperature of the graphitization furnace is detected during heating. When the temperature reaches the target heating temperature, the connection between the clamp and the connector of the graphitization furnace is disconnected, and a movement request is issued. When the system detects that other stations meet the movement conditions, each mobile boat moves one unit length, and the graphitization furnace moves to the next heating zone to continue heating. The transformer supplies power to the clamps of all heating zones simultaneously.

[0027] S4. When any graphitization furnace moves to the cooling station, the graphitization furnace is cooled.

[0028] S5. When any graphitization furnace moves to the unloading station, unload the graphitization furnace.

[0029] Compared with the prior art, the beneficial effects of the shipborne constant power power supply continuous graphitization system and operation method device provided by the present invention are as follows: the circular moving mechanism drives each graphitization furnace to pass through each heating zone in sequence. The heating target temperature of each heating zone is different. When the graphitization furnace passes through each heating zone in sequence, the temperature gradually increases. The heating power of the heating zone with a high heating target temperature is high, and the heating power of the heating zone with a low heating target temperature is low. However, since the transformer supplies power to the clamps of all heating zones at the same time, the total heating power can remain roughly stable after the system is running stably. This makes the power demand during the heating process more stable, improves the power utilization rate of the transformer, and reduces production costs. Attached Figure Description

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] To address the technical problem that the transformer supplying power to the graphitization furnace experiences low load in the initial heating stage and high load in the later heating stage, thus requiring the purchase of a high-power transformer, and that the transformer's power utilization rate is low in the initial heating stage, increasing production costs, this invention provides a shipborne constant power supply continuous graphitization system and its operation method. This system can make the power demand during the graphitization furnace heating process more stable, improve the power utilization rate of the transformer, and reduce production costs.

[0042] It should be noted that the shipborne constant power supply continuous graphitization system and operation method described in this invention are applicable to, but not limited to, graphitization systems. For ease of explanation, this invention only uses the application of the shipborne constant power supply continuous graphitization system and operation method to a graphitization system as an example for illustration. The principle of the shipborne constant power supply continuous graphitization system and operation method applied to other types of equipment is essentially the same as the principle applied to a graphitization system, and will not be elaborated here.

[0043] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a shipborne constant power supply continuous graphitization system according to an embodiment of the present invention. The shipborne constant power supply continuous graphitization system includes a ring moving mechanism 1, a clamping mechanism 2, and a transformer 3.

[0044] The annular moving mechanism 1 includes an annular water tank 11 and several moving boats 12. Each of the moving boats 12 can move along the annular water tank 11. Each of the moving boats 12 is equipped with a graphitization furnace, and each of the graphitization furnaces is equipped with a temperature sensor.

[0045] The clamping mechanism 2 includes a plurality of clamps 21, each clamp 21 being arranged sequentially along the moving direction of the moving boat 12, and each clamp 21 being used for electrical connection with the connector of the corresponding graphitization furnace.

[0046] The output terminal of the transformer 3 is electrically connected to each of the clamps 21.

[0047] In operation, each mobile boat 12 moves on the annular water tank 11, thereby driving the graphitization furnace sequentially through the charging station A1, heating station A2, cooling station A3, and unloading station A4. Each mobile boat 12 stops after moving one unit length, where the unit length is the distance between the midpoints of two adjacent mobile boats 12. When any graphitization furnace moves to the charging station A1, it is charged. The heating station A2 is divided into several heating zones A21, each with a preset target heating temperature. Along the moving direction of the mobile boats 12, the target heating temperature of each heating zone A21 increases sequentially. Each heating zone A21 is equipped with a clamp 21. When any graphitization furnace moves to a certain... When heating zone A21 is in operation, the clamp 21 of heating zone A21 is electrically connected to the connector of the graphitization furnace. During heating, the temperature of the graphitization furnace is monitored. When the temperature reaches the preset target heating temperature, the connection between the clamp 21 and the connector of the graphitization furnace is disconnected, and a movement request is issued. When the system detects that other stations meet the movement conditions, each moving boat 12 moves one unit length, and the graphitization furnace moves to the next heating zone A21 to continue heating. The transformer 3 supplies power to the clamps 21 of all heating zones A21 simultaneously. When any graphitization furnace moves to the cooling station A3, the graphitization furnace is cooled. When any graphitization furnace moves to the unloading station A4, the graphitization furnace is unloaded.

[0048] The technical solution provided by this invention uses a ring-shaped moving mechanism 1 to drive each graphitization furnace through each heating zone A21 in sequence. The target heating temperature of each heating zone A21 is different. As the graphitization furnace passes through each heating zone A21 in sequence, the temperature gradually increases. The heating power of the heating zone A21 with a higher target heating temperature is higher, and the heating power of the heating zone A21 with a lower target heating temperature is lower. However, since the transformer 3 supplies power to the clamps 21 of all heating zones A21 at the same time, the total heating power can remain relatively stable after the system is running stably. This makes the power demand during the heating process more stable, improves the power utilization rate of the transformer, and reduces production costs.

[0049] In one embodiment, please refer to Figure 1 and Figure 2 The annular water trough 11 includes two parallel transverse water troughs (including a left longitudinal water trough 111 and a right longitudinal water trough 112) and two parallel longitudinal water troughs (including a front transverse water trough 113 and a rear transverse water trough 114). The width of the transverse water troughs is slightly greater than the length of the mobile boat 12, and the width of the longitudinal water troughs is slightly greater than the width of the mobile boat 12. In this embodiment, the width of the transverse water troughs is 10-20cm greater than the length of the mobile boat 12, and the width of the longitudinal water troughs is 10-20cm greater than the width of the mobile boat 12. This can limit the movement of the mobile boat 12 and prevent it from rotating, and also avoid jamming the mobile boat 12, which would make it difficult for the mobile boat to move. The periphery of the mobile boat 12 is also fixed with buffers such as tires to reduce the collision intensity between the mobile boat 12 and the side wall of the annular water trough 11.

[0050] In one embodiment, please refer to Figures 1-3 The mobile boat 12 includes a hull 121 and a drive assembly 122. The drive assembly 122 is mounted on the hull 121 and includes a front nozzle 1221, a rear nozzle 1222, a left nozzle 1223, a right nozzle 1224, and a water pump 1225. The front nozzle 1221 is fixed to the hull 121 and its water outlet direction faces the front of the hull 121. The rear nozzle 1222 is fixed to the hull 121 and its water outlet direction faces the hull 121. The left nozzle 1223 is fixed to the hull 121 with the water outlet direction facing the left side of the hull 121, and the right nozzle 1224 is fixed to the hull 121 with the water outlet direction facing the right side of the hull 121. The inlet of the water pump 1225 is connected to the annular water tank 11, and the outlet of the water pump 1225 is selectively connected to the front nozzle 1221, the rear nozzle 1222, the left nozzle 1223, and the right nozzle 1224.

[0051] In this embodiment, the orientations of front, back, left, and right are defined as follows: when the moving boat 12 is located in the left longitudinal water channel 111, the front of the moving boat 12 in the direction of movement is the front, the rear of the moving boat 12 in the direction of movement is the rear, the left side of the moving boat 12 is the left, and the right side of the moving boat 12 is the right.

[0052] In use, when the moving boat 12 is located in the left longitudinal water tank 111, the outlet of the water pump 1225 is connected to the rear nozzle 1222. The water pump 1225 pumps water from the annular water tank 11 to the rear nozzle 1222 and sprays it backward, thereby propelling the hull 121 forward. When the moving boat 12 is located in the front transverse water tank 113, the outlet of the water pump 1225 is connected to the left nozzle 1223, thereby propelling the hull 121 to the right. When the moving boat 12 is located in the right longitudinal water tank... When the water tank 112 is in the water tank, the outlet of the water pump 1225 is connected to the front nozzle 1221. The water pump 1225 pumps water from the annular water tank 11 to the front nozzle 1221 and sprays it out backward, thereby pushing the hull 121 to move backward. When the moving boat 12 is located in the rear transverse water tank 114, the outlet of the water pump 1225 is connected to the right nozzle 1224, thereby pushing the hull 121 to move to the left. In this way, the hull 121 can be driven to make an annular motion along the annular water tank 11.

[0053] In one embodiment, please refer to Figures 1-3 The number of front nozzles 1221 is two, and they are symmetrically arranged at both ends of the front side of the hull 121. The number of rear nozzles 1222 is two, and they are symmetrically arranged at both ends of the rear side of the hull 121. The number of left nozzles 1223 is two, and they are symmetrically arranged at both ends of the left side of the hull 121. The number of right nozzles 1224 is two, and they are symmetrically arranged at both ends of the right side of the hull 121, which can improve stability.

[0054] In one embodiment, please refer to Figures 1-3 The drive assembly 122 further includes a first five-way valve 1226 and a second five-way valve 1227. The first port of the first five-way valve 1226 is connected to the outlet of the water pump 1225, the second port of the first five-way valve 1226 is connected to one of the right nozzles 1224, the third and fourth ports of the first five-way valve 1226 are respectively connected to two front nozzles 1221, and the fifth port of the first five-way valve 1226 is connected to one of the left nozzles 1223. The first port of the second five-way valve 1227 is connected to the outlet of the water pump 1225, the second port of the second five-way valve 1227 is connected to another right nozzle 1224, the third and fourth ports of the second five-way valve 1227 are respectively connected to two rear nozzles 1222, and the fifth port of the second five-way valve 1227 is connected to another left nozzle 1223.

[0055] In use, the outlet of the water pump 1225 can be selectively connected to the front nozzle 1221, the rear nozzle 1222, the left nozzle 1223, and the right nozzle 1224 by selectively opening and closing the various ports of the first five-way valve 1226 and the second five-way valve 1227. For example, when it is necessary for the outlet of the water pump 1225 to be connected to the two front nozzles 1221, the first port, the third port, and the fourth port of the first five-way valve 1226 are opened, and all other ports of the first five-way valve 1226 and the second five-way valve 1227 are closed, and the outlet of the water pump 1225 will be connected to the two front nozzles 1221.

[0056] In one embodiment, please refer to Figures 1-3 The first port of the first five-way valve 1226 is connected to the outlet of the water pump 1225 via the first branch pipe 1228. The first port of the second five-way valve 1227 is connected to the outlet of the water pump 1225 via the second branch pipe 1229.

[0057] In one embodiment, please refer to Figures 1-5 The mobile boat 12 also includes a plurality of first clamping members 123 and a plurality of second clamping members 124. The plurality of first clamping members 123 are respectively arranged on the left and right sides of the hull 121, and the plurality of second clamping members 124 are respectively arranged on the front and rear sides of the hull 121. In use, when the hull 121 is located in the left longitudinal channel 111 or the right longitudinal channel 112, the first clamping members 123 clamp the hull 121 between the two side walls of the left longitudinal channel 111 or the right longitudinal channel 112. When the hull 121 is located in the front transverse channel 113 or the rear transverse channel 114, the second clamping members 124 clamp the hull 121 between the two side walls of the front transverse channel 113 or the rear transverse channel 114.

[0058] In one embodiment, please refer to Figures 1-5 The first clamping component 123 includes a first clamping cylinder 1231, a first mounting block 1232, a first spring 1233, and a first friction plate 1234. The cylinder body of the first clamping cylinder 1231 is fixed to the hull 121. The output shaft of the first clamping cylinder 1231 is fixedly connected to the first mounting block 1232. The two ends of the first spring 1233 are fixedly connected to the first mounting block 1232 and the first friction plate 1234, respectively. The first friction plate 1234 is used to abut against the left inner wall or the right inner wall of the longitudinal water channel. When the mobile vessel 12 is located in the left longitudinal water channel 111 or the right longitudinal water channel 112 and moves into place, the first clamping cylinder 1231 pushes the first friction plates 1234 on both sides to abut against the two inner side walls of the left longitudinal water channel 111 or the right longitudinal water channel 112, thereby clamping the mobile vessel 12 in the left longitudinal water channel 111 or the right longitudinal water channel 112, preventing the mobile vessel 12 from shaking and affecting the electrical connection or unloading.

[0059] In one embodiment, please refer to Figures 1-5 The second clamping component 124 includes a second clamping cylinder 1241, a second mounting block 1242, a second spring 1243, and a second friction plate 1244. The cylinder body of the second clamping cylinder 1241 is fixed to the hull 121. The output shaft of the second clamping cylinder 1241 is fixedly connected to the second mounting block 1242. The two ends of the second spring 1243 are fixedly connected to the second mounting block 1242 and the second friction plate 1244, respectively. The second friction plate 1244 is used to abut against the left or right inner wall of the transverse water channel. When the moving boat 12 is located in the front transverse water channel 113 or the rear transverse water channel 114 and moves into place, the second clamping cylinder 1241 pushes the second friction plates 1244 on both sides to abut against the two inner walls of the front transverse water channel 113 or the rear transverse water channel 114, thereby clamping the moving boat 12 in the front transverse water channel 113 or the rear transverse water channel 114 and preventing the moving boat 12 from shaking.

[0060] In one embodiment, please refer to Figures 6-8 The clamp 21 includes a housing 211, two clamping assemblies 212, and an opening drive 213. The two clamping assemblies 212 are respectively arranged on both sides inside the housing 211. Each clamping assembly 212 includes a mounting plate 2121, an elastic element 2122, and an electrode plate 2123. The mounting plate 2121 is fixed inside the housing 211. The two ends of the elastic element 2122 are fixedly connected to the mounting plate 2121 and the electrode plate 2123, respectively. The electrode plate 2123 is used to abut against a connector of the graphitization furnace. The opening drive 213 is used to move the electrode plates 2123 of the two clamping assemblies 212 away from each other. In this embodiment, a clearance groove 2111 is provided on the end face of the housing 211 near the track, which is used to allow the connector to enter the housing 211.

[0061] In one embodiment, please refer to Figures 6-8 The mounting plate 2121 has two guide holes, and the clamping assembly 212 also includes two guide rods 2124. One end of the two guide rods 2124 is fixed to the electrode plate 2123, and the other end of the two guide rods 2124 is slidably inserted into the two guide holes respectively. By setting the guide rods 2124, the stability of the electrode plate 2123 during movement can be improved.

[0062] In one embodiment, please refer to Figures 6-8The opening drive component 213 includes an opening motor 2131, a sleeve 2132, and two pull ropes 2133. The output shaft of the opening motor 2131 is coaxially and fixedly connected to the sleeve 2132. One end of each of the two pull ropes 2133 is fixed and wound around the sleeve 2132, and the other end of each pull rope is fixedly connected to the two electrode plates 2123 respectively. In use, when it is necessary to separate the electrode plates 2123 from the joint of the graphitization furnace, the opening motor 2131 drives the sleeve 2132 to rotate, winding the pull ropes 2133, thereby moving the two electrode plates 2123 away. When it is necessary to clamp the electrode plates 2123 to the joint of the graphitization furnace, the opening motor 2131 drives the sleeve 2132 to rotate in the opposite direction, unwinding the pull ropes 2133. Under the action of the elastic element 2122, the two electrode plates 2123 move closer to each other, thereby clamping the joint of the graphitization furnace.

[0063] In one embodiment, please refer to Figures 6-8 The opening drive component 213 also includes several guide wheels 2134, each guide wheel 2134 is rotatably disposed on the box body 211, and the pull rope 2133 is sequentially wound around each of the guide wheels 2134.

[0064] In one embodiment, please refer to Figures 6-9 The clamping mechanism 2 further includes an adjustment component 22, which includes a fixed base 221, a lifting cylinder 222, a lifting plate 223, a translation cylinder 224, and a connecting plate 225. The cylinder body of the lifting cylinder 222 is fixed to the fixed base 221, and the output shaft of the lifting cylinder 222 is fixedly connected to the lifting plate 223. The cylinder body of the translation cylinder 224 is fixed to the lifting plate 223 via a clamp 226, and the output shaft of the translation cylinder 224 is fixedly connected to the connecting plate 225. The connecting plate 225 is fixedly connected to each of the boxes 211 via several connecting rods 227. In use, the lifting cylinder 222 is used to adjust the height of the connecting plate 225, thereby adjusting the height of each clamp 21 so that the height of the clamp 21 is equal to the height of the graphitization furnace joint. Since the height of the graphitization furnace joint may change with the different drafts of the hull 121, the height of the clamp 21 needs to be adjustable. The translation cylinder 224 is used to push each clamp 21 into contact with the graphitization furnace joint.

[0065] The working principle of clamping mechanism 2 is as follows:

[0066] (1) When power is required, the sleeve 2132 is rotated by the opening motor 2131 to wind up the pull rope 2133, thereby moving the two pole plates 2123 away from each other, so that the distance between the two pole plates 2123 is greater than the distance between the two joints of the graphitization furnace. Then, the height of the connecting plate 225 is adjusted by the lifting cylinder 222, thereby adjusting the height of each clamp 21, so that the height of the clamp 21 is equal to the height of the joint of the graphitization furnace. Then, the connecting plate 225 is moved closer to the graphitization furnace by the translation cylinder 224, so that the two pole plates 2123 are moved to the outside of the two joints of the corresponding graphitization furnace. Then, the sleeve 2132 is rotated in the opposite direction by the opening motor 2131 to unwind the pull rope 2133. The two pole plates 2123 approach each other under the action of the elastic element 2122, thereby clamping the joint of the graphitization furnace and realizing power connection.

[0067] (2) When it is necessary to disconnect the connection, the sleeve 2132 is rotated by opening the motor 2131 to wind up the pull rope 2133, thereby moving the two electrode plates 2123 away from each other, so that the two electrode plates 2123 are separated from the two joints of the graphitization furnace. Then, the connecting plate 223 is moved away from the graphitization furnace by the translation cylinder 224 to achieve power disconnection.

[0068] The present invention also provides an operation method for a shipborne constant power supply continuous graphitization system, applicable to the aforementioned shipborne constant power supply continuous graphitization system, and includes the following steps:

[0069] S1. Each mobile boat 12 moves on the annular water tank 11, thereby driving the graphitization furnace to pass through the charging station A1, heating station A2, cooling station A3 and unloading station A4 in sequence. Each mobile boat 12 stops once after moving one unit length, and the unit length is the distance between the midpoints of two adjacent graphitization furnaces.

[0070] S2. When any graphitization furnace moves to the charging station A1, the graphitization furnace is charged.

[0071] S3. Heating station A2 is divided into several heating zones A21. Each heating zone A21 has a preset heating target temperature. Along the moving direction of the moving boat 12, the heating target temperature of each heating zone A21 increases sequentially. Each heating zone A21 is equipped with a clamp 21. When any graphitization furnace moves to a certain heating zone A21, the clamp 21 of the heating zone A21 is electrically connected to the connector of the graphitization furnace. The temperature of the graphitization furnace is detected during heating. When the temperature reaches the preset heating target temperature, the connection between the clamp 21 and the connector of the graphitization furnace is disconnected, and a movement request is issued at the same time. When the system detects that other stations meet the movement conditions, each moving boat 12 moves one unit length, and the graphitization furnace moves to the next heating zone A21 and continues to heat in the next heating zone A21. The transformer 3 supplies power to the clamps 21 of all heating zones A21 at the same time.

[0072] S4. When any graphitization furnace moves to the cooling station A3, the graphitization furnace is cooled.

[0073] S5. When any graphitization furnace moves to the unloading station A4, the graphitization furnace is unloaded.

[0074] The technical solution provided by this invention uses a ring-shaped moving mechanism 1 to drive each graphitization furnace through each heating zone A21 in sequence. The target heating temperature of each heating zone A21 is different. As the graphitization furnace passes through each heating zone A21 in sequence, the temperature gradually increases. The heating power of the heating zone A21 with a higher target heating temperature is higher, and the heating power of the heating zone A21 with a lower target heating temperature is lower. However, since the transformer 3 supplies power to the clamps 21 of all heating zones A21 at the same time, the total heating power can remain relatively stable after the system is running stably. This makes the power demand during the heating process more stable, improves the power utilization rate of the transformer, and reduces production costs.

[0075] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
