Description

Technical Field

[0001] The present invention provides continuous carbonization, graphitization and purification equipment, methods and readable storage media, belonging to the technical field of carbon felt processing. Background Art

[0002] As a thermal insulation material, hard carbon felt is widely used in vacuum thermal equipment such as high-temperature purification furnaces, silicon carbide coating furnaces, silicon carbide crystal growth furnaces, and tantalum carbide coating furnaces. The main manufacturing processes of hard carbon felt include molding, curing, carbonization, graphitization, and purification. Currently, the carbonization of hard carbon felt requires placing the hard carbon felt in an intermittent carbonization furnace, heating, holding, and cooling it, and then removing it from the intermittent carbonization furnace. It then enters an intermittent graphitization furnace, where it also needs to be heated, held, and cooled before being removed from the graphitization furnace. If high-quality hard carbon felt is required, it also needs to be placed in an intermittent purification furnace for further purification. This results in long production times, high production costs, and high energy consumption. The price of hard carbon felt products remains high, which seriously restricts industrial development.

[0003] Based on this, a Chinese utility model patent (CN203699918U) proposes a continuous high-temperature furnace for carbonization and graphitization. The furnace includes a feed chamber, a graphite door, a boat push mechanism, a carbonization chamber, a transition chamber, a graphitization chamber, and a discharge chamber. The carbonization chamber and the graphitization chamber are connected by the transition chamber, allowing the carbonized graphite raw material to pass directly into the graphitization furnace after passing through the transition chamber, thereby achieving continuous carbonization and graphitization production. However, the carbonization chamber and the graphitization chamber are separately arranged, which occupies a large area of ​​equipment and has high manufacturing costs. Summary of the Invention

[0050] In this embodiment, four first steering mechanisms 38 are provided, namely, first steering mechanism 1 28, first steering mechanism 2 29, first steering mechanism 3 31, and first steering mechanism 4 33. A first transmission device is rotatably connected to the first steering mechanism 38. Two second steering mechanisms are provided, namely, second steering mechanism 1 30 and second steering mechanism 2 32. A second transmission device is rotatably connected to the second steering mechanism. The first and second transmission devices cooperate with each other. First steering mechanism 1 28 is movably connected to the carbonization zone of the carbonization and graphitization chamber 4. First steering mechanism 2 29 is movably connected to the graphitization zone of the carbonization and graphitization chamber 4.

Second steering mechanism 2 32 is movably connected to the second transition chamber 9. First steering mechanism 4 33 is movably connected to the cooling chamber 6.

[0051] Specifically, a first through hole is formed in the bottom of the processing chamber, and the first steering mechanism 38 is connected to the processing chamber through the first through hole. The first steering mechanism 38 is movably connected to the processing chamber through the first through hole. More specifically, the first steering mechanism 38 includes a lifting mechanism and a reversing mechanism. The lifting mechanism includes a first rotating shaft 203 and a lifting shaft 205. The first rotating shaft 203 and the lifting shaft 205 are connected to each other. The first rotating shaft 203 is connected to the output end of the lifting motor 201 through a connecting key 202. A lifting nut 204 is movably provided on the first rotating shaft 203. The lifting nut 204 is fixedly connected to the lifting shaft 205. The lifting shaft 205 is outer-mounted with a second rotating shaft 210. The lifting shaft 205 is rotatably connected to the second rotating shaft 210, that is, the second rotating shaft 210 can rotate around the center axis of the second rotating shaft 210. The second rotating shaft 210 is also connected to a pulley 206 and a base plate 211. The pulley 206 is connected to the pulley 206 rotatably connected to the output end of the rotating motor 208 through a belt 207. The material 15 is placed on the base plate 211, and the material 15 is located in the processing bin. The second rotating shaft 210 is connected on the processing chamber by the first magnetic fluid sealing assembly 209, and the first magnetic fluid sealing assembly 209 is closely matched with the first through hole, to achieve the purpose of sealing.The structure of the second steering mechanism is identical with the structure of the first steering mechanism 38, and the second rotating shaft 210 of the second steering mechanism is connected on the transition chamber by the second magnetic fluid sealing assembly of the second steering mechanism.The second magnetic fluid sealing assembly is closely matched with the second through hole that is arranged at the transition chamber bottom, to achieve the purpose of sealing, and the second steering mechanism can be accessed in the transition chamber by the second through hole.The second magnetic fluid sealing assembly is identical with the structure of the first magnetic fluid sealing assembly 209.

[0052] The carbonization and graphitization chamber 4 includes a carbonization zone and a graphitization zone. The carbonization zone and the graphitization zone are arranged separately. Integrating the carbonization zone and the graphitization zone in the carbonization and graphitization chamber 4 can save manufacturing costs and reduce floor space. Taking PAN-based hard carbon felt as an example, when PAN-based hard carbon felt is carbonized at high temperature, non-carbon elements in the PAN-based fibers are discharged in the form of gas, such as ammonia, nitrogen, and hydrogen. There are also some resinous substances in the PAN-based fibers that produce a large amount of tar and gas at high temperature, forming liquid tar in the vacuum pipe. The role of high-temperature graphitization of PAN-based hard carbon felt in the graphitization zone is mainly to improve its structure and enhance its performance, that is, to transform the structure of the PAN-based carbon material from a disordered carbonaceous structure to an ordered graphite structure, and only a small amount of gas is discharged during the graphitization process. Therefore, the carbonization zone of the loading bin 3 and the carbonization graphitization bin 4 is connected to the first vacuum pump 1 through a cyclone filter device 16 installed in the exhaust pipeline, which is used to quickly condense the tar generated during the carbonization process into liquid and store it in the liquid storage tank of the cyclone filter device 16, preventing the tar from entering the interior of the first vacuum pump 1 and avoiding impurities discharged during carbonization from contaminating the material 15 in the graphitization zone.

[0053] The carbonization zone is equipped with a first heating system and a first temperature measurement system 34. When the output power reaches a set value, the temperature of the carbonization zone can reach 1100°C. The first temperature measurement system 34 is electrically connected to the first heating system to form a feedback loop. The first heating system regulates the temperature of the carbonization zone to meet the carbonization requirements. The graphitization zone is equipped with a second heating system and a second temperature measurement system 35. When the output power reaches a set value, the temperature of the carbonization zone can reach 2000°C. The second temperature measurement system 35 is electrically connected to the second heating system to form a feedback loop. The second heating system regulates the temperature of the graphitization zone to meet the graphitization requirements.

[0054] The carbonization zone is also equipped with a first vacancy detection device and several first transmission members, and the first transmission members cooperate with each other. In this embodiment, two first transmission members are provided. The two first transmission members and the first transmission device on the first steering mechanism 28 constitute three first working parts 17. The first steering mechanism 28 is installed at one end of the carbonization zone close to the upper bin 3, that is, the first steering mechanism 28 is installed at the first working part 17 at the leftmost end of the carbonization zone. The first steering mechanism 28 cooperates with the third push rod 39 to transmit the material 15 from the upper bin 3 to the first transmission device of the first steering mechanism 28, that is, the material 15 can be transmitted from the upper bin 3 to the first working part 17 at the leftmost end of the carbonization zone. The first steering mechanism 28 cooperates with the first push rod 21 to transmit the material 15 from the first transmission device of the first steering mechanism 28 to the next first working part 17 of the carbonization zone.

[0055] The graphitization zone is equipped with a second vacancy detection device and several second transmission members. In this embodiment, two second transmission members are provided. These two second transmission members, together with the first transmission member on the first steering mechanism 29, form three second working sections 18. The first steering mechanism 29 is installed at the end of the graphitization zone away from the loading bin 3, that is, the first steering mechanism 29 is installed at the second working section 18 at the rightmost end of the graphitization zone. The second transmission members cooperate with each other. The upper surfaces of the second transmission members and the first transmission members are coplanar. The first transmission member, the second transmission member, the first steering mechanism 1 28, and the first steering mechanism 2 29 cooperate with the first push rod 21 connected to the carbonization zone to transfer the material 15 from the carbonization zone to the graphitization zone. The first steering mechanism 2 29 and the second steering mechanism 1 30 cooperate with the first push rod 21 connected to the graphitization zone to transfer the material 15 from the graphitization zone to the second steering mechanism 1 30 in the first transition bin 8, specifically to the second transmission member on the second steering mechanism 1 30.

The first steering mechanism 3 (31) is installed at the end of the purification chamber 5 away from the first transition chamber 8, specifically, the rightmost third working section 19 in the purification chamber 5. The second transmission device and third transmission components on the second steering mechanism 1 (30) interact with the second push rod 22 connected to the first transition chamber 8 to transfer material 15 from the leftmost third working section 19 to the rightmost third working section 19 in the purification chamber 5.

[0058] A third heating system and a third temperature measuring system 36 are also installed in the purification chamber 5. When the output power reaches the set value, the temperature in the purification chamber 5 can reach 2400°C. The third temperature measuring system 36 is electrically connected to the third heating system to form a feedback loop. The third heating system regulates the temperature in the purification chamber 5 to control the temperature of the purification chamber 5 to meet the purification requirements.

[0059] A third vacancy detection device is installed in the first transition chamber 8 and is electrically connected to the control system 40. It is used to detect whether material 15 is placed on the second conveying device of the second diverting mechanism 1 30 in the first transition chamber 8. A fourth vacancy detection device is installed in the purification chamber 5 and is electrically connected to the control system 40. It is used to detect whether material 15 is placed on the third working section 19 at the rightmost end of the purification chamber 5. Specifically, the fourth vacancy detection device is used to detect whether material 15 is placed on the first conveying device of the first diverting mechanism 31.

[0060] The first conveying device on the first steering mechanism 31, the second conveying device on the second steering mechanism 2 32, and the first push rod 21 connected to the purification chamber 5 cooperate with each other to transfer the material 15 from the purification chamber 5 to the second transition chamber 9, specifically, to the second conveying device on the second steering mechanism 2 32. The second conveying device on the second steering mechanism 2 32 cooperates with the second push rod 22 connected to the second transition chamber 9 to transfer the material 15 from the second transition chamber 9 to the cooling chamber 6.

[0061] The cooling bin 6 is equipped with five fourth transmission members, which cooperate with each other in pairs. The five fourth transmission members and the first transmission device on the first steering mechanism 4 33 constitute six fourth working sections 20. The first steering mechanism 4 33 is installed at the end of the cooling bin 6 away from the second transition bin 9, that is, the first steering mechanism 4 33 is installed on the rightmost fourth working section 20 in the cooling bin 6. The second transmission device and the fourth transmission members on the second steering mechanism 2 32 interact with the second push rod 22 connected to the second transition bin 9 to transfer the material 15 from the leftmost fourth working section 20 in the cooling bin 6 to the rightmost fourth working section 20. The first transmission device on the first steering mechanism 4 33 cooperates with the third push rod 39 connected to the cooling bin 6 to transfer the material 15 from the cooling bin 6 to the discharge bin 7.

[0062] A fourth temperature measuring system 37 is also installed in the cooling bin 6. The fourth temperature measuring system 37 is electrically connected to the forced cooling fan 25 to form a feedback loop. The rotation speed of the forced cooling fan 25 is adjusted according to the amount of material 15 that needs to be cooled and the transmission speed of the fourth transmission component to ensure that the material 15 meets the discharge temperature requirements before being transmitted to the discharge bin 7.

[0063] A fifth empty position detection device is installed in the second transition bin 9 and is electrically connected to the control system 40 . The fifth empty position detection device is used to detect whether material 15 is placed on the second transmission device of the second steering mechanism 2 32 in the second transition bin 9 .

[0064] A sixth vacancy detection device is installed within the cooling chamber 6 and is electrically connected to the control system 40. This device is used to detect whether material 15 is placed on the fourth working section 20 at the rightmost end of the cooling chamber 6. More specifically, the first, second, third, and fourth transmission members, the first and second transmission devices are each comprised of a plurality of parallel graphite rollers 27. Rotating the graphite rollers 27 moves the tray 2 placed thereon, thereby conveying the material 15.

[0065] The graphite roller 27 can rotate around its central axis, and the graphite roller 27 can be driven manually or electrically.

[0066] Multiple third gate valves 12 are also movably connected to the carbonization and graphitization chamber 4 and the purification chamber 5 to prevent the high temperatures within the carbonization and graphitization chamber 4 and the purification chamber 5 from affecting the performance of the propulsion component 14. Specifically, each third gate valve 12 corresponds to a first push rod 21. When the first push rod 21 is inserted into the carbonization and graphitization chamber 4 or the purification chamber 5 to push the material 15, the third gate valve 12 is opened. When the first push rod 21 pushes the material 15 to the designated position, the first push rod 21 is withdrawn from the carbonization and graphitization chamber 4 or the purification chamber 5, and the third gate valve 12 is closed. In this embodiment, three third gate valves 12 are provided, two of which are movably connected to the carbonization and graphitization chamber 4. The two third gate valves 12 are placed between the carbonization and graphitization chamber 4 and the corresponding first push rods 21. More specifically, the two third gate valves 12 correspond to the carbonization zone and the graphitization zone, respectively; the other third gate valve 12 is movably connected to the purification chamber 5, and the third gate valve 12 is placed between the purification chamber 5 and the first push rod 21 corresponding to the purification chamber 5.

[0067] The transition bin is also movably connected to a fourth gate valve 13, which corresponds one-to-one to the second push rod 22. When the second push rod 22 needs to be extended into the transition bin to push the material 15, the fourth gate valve 13 is opened. When the second push rod 22 is used to push the material 15 to the specified position, the second push rod 22 is pulled out of the transition bin and the fourth gate valve 13 is closed.

[0068] The first transition chamber 8 and the purification chamber 5 are connected to the second vacuum pump 23 via a first filter tank 24 installed in a first vacuum line 26. The first vacuum line 26 is connected between the first transition chamber 8, the purification chamber 5, and the second vacuum pump 23. That is, the first transition chamber 8, the purification chamber 5, and the second vacuum pump 23 are interconnected via the first vacuum line 26. The second transition chamber 9 and the cooling chamber 6 are connected to the output end of the forced cooling fan 25 via a second filter tank 42 installed in a second vacuum line 41. The vacuum line 26 is connected between the second transition chamber 9, the cooling chamber 6, and the output end of the forced cooling fan 25. That is, the second transition chamber 9, the cooling chamber 6, and the output end of the forced cooling fan 25 are interconnected via the second vacuum line 41.

[0069] In this embodiment, the material 15 is PAN-based hard carbon felt.

[0070] The present invention provides a continuous carbonization, graphitization, and purification method, which uses the above-mentioned continuous carbonization, graphitization, and purification equipment and includes the following steps:

[0071] Step S1: Place the first material to be carbonized, graphitized, and purified into the loading bin 3, and evacuate the loading bin 3 using the first vacuum pump 1;

[0072] Specifically, the material tray 2 containing the first material to be carbonized, graphitized and purified is placed in the upper bin 3 , and after the upper bin 3 is closed, the first vacuum pump 1 is started to evacuate the upper bin 3 .

[0073] Step S2: Open the first gate valve 10 between the loading bin 3 and the carbonization and graphitization bin 4 to feed the first material into the carbonization zone of the carbonization and graphitization bin 4 for carbonization treatment to obtain the second material. Then, the first transmission member and the second transmission member cooperate with each other to feed the second material into the graphitization zone of the carbonization and graphitization bin 4 for graphitization treatment to obtain the third material. The specific steps include:

[0074] Step S21, open the first gate valve 10 movably connected between the upper silo 3 and the carbonization and graphitization silo 4 and the valve of the upper silo 3, drive the third push rod 39 corresponding to the valve of the upper silo 3, the third push rod 39 is movably connected to the upper silo 3, and the third push rod 39 acts on the material tray 2 to push the material tray 2 into the first working part 17 at the leftmost end of the carbonization zone. At this time, the transmission direction of the first working part 17 at the leftmost end in the carbonization zone is consistent with the movement direction of the material tray 2, and then drive the third push rod 39 corresponding to the valve of the upper silo 3 to withdraw from the carbonization and graphitization silo 4 and move it to the initial position, and close the first gate valve 10 and the valve of the upper silo 3.

[0075] Before pushing the material tray 2 into the first working part 17 at the leftmost end of the carbonization zone, the first vacancy detection device transmits the signal collected to the control system 40 indicating whether a material tray 2 is placed on the first working part 17, and the control system 40 controls the third push rod 39 corresponding to the valve of the upper hopper 3 to operate. Specifically, when the first vacancy detection device detects that a material tray 2 is placed on the first working part 17 at the leftmost end of the carbonization zone, the control system 40 controls the third push rod 39 corresponding to the valve of the upper hopper 3 to not operate after receiving the signal. When the first vacancy detection device detects that there is no material tray 2 on the first working part 17 at the leftmost end of the carbonization zone, the control system 40 controls the third push rod 39 corresponding to the valve of the upper hopper 3 to enter the upper hopper 3 and push the material tray 2 onto the first working part 17 at the leftmost end of the carbonization zone after receiving the signal.

[0076] Step S22: Activate the first steering mechanism 28. The base plate 211 of the first steering mechanism 28 acts on the first conveying device of the first steering mechanism 28 on the first working section 17. The lifting mechanism of the first steering mechanism 28 lifts the material tray 2 placed on the first conveying device of the first steering mechanism 28 and then activates the reversing mechanism to change the conveying direction of the first conveying device of the first steering mechanism 28, aligning the conveying direction of the first conveying device of the first steering mechanism 28 with the conveying direction of the first conveying member. This aligns the rotation direction of the multiple graphite rollers 27 on the first conveying device of the first steering mechanism 28 with the rotation direction of the multiple graphite rollers 27 on the first conveying member installed in the carbonization zone. After adjusting the conveying direction of the first conveying device of the first steering mechanism 28, the lifting mechanism is activated to return the lifted material tray 2 to its original position, aligning the first conveying device and the first conveying member of the first steering mechanism 28 in the same plane.

[0077] Step S23: Open the third gate valve 12 movably connected to the left side of the carbonization zone of the carbonization and graphitization bin 4, drive the first push rod 21 corresponding to the third gate valve 12 and act on the material tray 2, push the material tray 2 to move to the next first working part 17, and then the first push rod 21 is pulled out of the carbonization and graphitization bin 4 and moves to the initial position, and close the third gate valve 12.

[0078] Step S24, repeating steps S21 to S23, when the second tray 2 is moved to the first working section 17 where the previous tray 2 is located, the first tray 2 is pushed to the next first working section 17, so that multiple trays 2 containing the first material to be carbonized, graphitized, and purified can be moved to the carbonization zone for carbonization operation.

[0079] Since the carbonization zone and the graphitization zone are integrated in the carbonization and graphitization chamber 4, the corresponding first transmission member and the second transmission member have the same structure, and the upper surfaces of the first transmission member and the second transmission member are in the same plane. By repeating steps S21 to S24, the carbonized first material can be pushed to the graphitization zone for graphitization, thereby obtaining the third material.

[0080] Before pushing the material tray 2 to the next first working section 17, the second vacancy detection device transmits a signal to the control system 40, detecting whether a material tray 2 is placed on the second working section 18 at the rightmost end of the graphitization zone. The control system 40 then controls the first push rod 21 corresponding to the third gate valve 12 in the carbonization zone to actuate. Specifically, when the second vacancy detection device detects that a material tray 2 is placed on the second working section 18 at the rightmost end of the graphitization zone, the control system 40 controls the first push rod 21 to remain in actuated upon receiving the signal. When the second vacancy detection device detects that no material tray 2 is placed on the second working section 18 at the rightmost end of the graphitization zone, the control system 40 controls the first push rod 21 corresponding to the third gate valve 12 in the carbonization zone to enter the carbonization zone to push the material tray 2 to the next first working section 17 upon receiving the signal.

[0081] Step S3: Open the second gate valve 11 between the carbonization and graphitization chamber 4 and the first transition chamber 8, and the second gate valve 11 between the first transition chamber 8 and the purification chamber 5, and send the third material into the purification chamber 5 for purification to obtain the fourth material. This specifically includes the following steps:

[0082] Step S31: Start the first steering mechanism 29. The bottom plate 211 of the first steering mechanism 29 acts on the first transmission device of the first steering mechanism 29 on the second working portion 18 at the rightmost end of the graphitization zone to adjust its transmission direction so that it is consistent with the transmission direction of the second transmission device of the second steering mechanism 1 30 located in the first transition chamber 8.

[0083] Step S32: After opening the second gate valve 11 movably connected between the carbonization and graphitization bin 4 and the first transition bin 8, and the third gate valve 12 movably connected to the graphitization zone end of the carbonization and graphitization bin 4, the first push rod 21 corresponding to the third gate valve 12 is driven to push the material tray 2 located at the second working part 18 at the rightmost end of the graphitization zone to the second transmission device of the second steering mechanism 30. At this time, the transmission direction of the second transmission device of the second steering mechanism 30 is consistent with the moving direction of the material tray 2. Then, the first push rod 21 is driven to withdraw the carbonization and graphitization bin 4, and then the corresponding third gate valve 12 and the second gate valve 11 movably connected between the carbonization and graphitization bin 4 and the first transition bin 8 are closed.

[0084] A third vacancy detection device is installed in the first transition chamber 8. Before pushing the material tray 2 onto the second conveying device of the second steering mechanism 30, the third vacancy detection device transmits a signal to the control system 40, detecting whether a material tray 2 is placed on the second conveying device of the second steering mechanism 30. The control system 40 then controls the first push rod 21 corresponding to the third gate valve 12 in the graphitization zone to operate. Specifically, when the third vacancy detection device detects that a material tray 2 is placed on the second conveying device of the second steering mechanism 30, the control system 40 controls the first push rod 21 corresponding to the third gate valve 12 in the graphitization zone to remain inactive. When the third vacancy detection device detects that no material tray 2 is placed on the second conveying device of the second steering mechanism 30, the control system 40 controls the first push rod 21 corresponding to the third gate valve 12 in the graphitization zone to enter the graphitization zone and push the material tray 2 placed on the second working section 18 at the rightmost end of the graphitization zone to the second conveying device of the second steering mechanism 30 in the first transition chamber 8.

[0085] Step S33 , starting the second vacuum pump 23 to completely pump out the gas entering the first transition chamber 8 from the carbonization and graphitization chamber 4 to prevent the gas from entering the purification chamber 5 .

[0086] Step S34: The bottom plate 211 of the second steering mechanism 30 is caused to act on the second conveying device of the second steering mechanism 30 in the first transition chamber 8. The lifting mechanism of the second steering mechanism 30 is activated to lift the material tray 2 placed on the second conveying device of the second steering mechanism 30. The reversing mechanism is then activated to change the conveying direction of the second conveying device of the second steering mechanism 30, thereby aligning the conveying direction of the second conveying device of the second steering mechanism 30 with the conveying direction of the third conveying element of the third working section 19 in the purification chamber 5. After adjusting the conveying direction of the second conveying device of the second steering mechanism 30, the lifting mechanism is activated to lower the lifted material tray 2 back to its original position, thereby aligning the upper surface of the second conveying device of the second steering mechanism 30 with the upper surface of the third conveying element.

[0087] Step S35, open the fourth gate valve 13 movably connected to the first transition chamber 8 and the second gate valve 11 movably connected between the first transition chamber 8 and the purification chamber 5, drive the second push rod 22 corresponding to the fourth gate valve 13 and act on the material tray 2, push the material tray 2 to move to the third working part 19 at the leftmost end of the purification chamber 5, then the second push rod 22 is pulled out of the first transition chamber 8 and moves to the initial position, and finally close the fourth gate valve 13 and the second gate valve 11.

[0088] A fourth vacancy detection device is installed in the purification chamber 5. Before pushing the material tray 2 into the purification chamber 5, the fourth vacancy detection device transmits a signal to the control system 40, detecting whether a material tray 2 is placed on the third working section 19 at the rightmost end of the purification chamber 5. The control system 40 then controls the second push rod 22 corresponding to the fourth gate valve 13 of the first transition chamber 8 to operate. Specifically, when the fourth vacancy detection device detects that a material tray 2 is placed on the first transmission device of the first steering mechanism 3 31 in the purification chamber 5, the control system 40 controls the second push rod 22 corresponding to the fourth gate valve 13 of the first transition chamber 8 to remain inactive. When the fourth vacancy detection device detects that no material tray 2 is placed on the third working section 19 at the rightmost end of the purification chamber 5, the control system 40 controls the second push rod 22 corresponding to the fourth gate valve 13 of the first transition chamber 8 to enter the first transition chamber 8 and push the material tray 2 placed in the first transition chamber 8 to be transferred to the third working section 19 at the leftmost end of the purification chamber 5.

[0089] Step S36: Repeat steps S31 to S35 to push a plurality of third materials to be purified into the purification chamber 5 for purification.

[0090] When executing step S33 and step S34, the order of the two can be interchanged.

[0091] Step S4: Open the second gate valve 11 provided between the purification chamber 5 and the second transition chamber 9 and the second gate valve 11 provided between the second transition chamber 9 and the cooling chamber 6 to send the fourth material into the cooling chamber 6 for cooling. The specific steps include:

[0092] Step S41, start the first steering mechanism three 31, and the bottom plate 211 of the first steering mechanism three 31 acts on the first transmission device of the first steering mechanism three 31 in the purification warehouse 5 to adjust the transmission direction of the first transmission device so that it is consistent with the transmission direction of the second transmission device of the second steering mechanism two 32 located in the second transition warehouse 9.

[0093] Step S42, after opening the second gate valve 11 movably connected between the purification warehouse 5 and the second transition warehouse 9 and the third gate valve 12 movably connected to the purification warehouse 5, drive the first push rod 21 corresponding to the third gate valve 12 to push the material tray 2 located in the third working part 19 at the rightmost end of the purification warehouse 5 to move to the second transmission device of the second steering mechanism 2 32 in the second transition warehouse 9. At this time, the transmission direction of the second transmission device of the second steering mechanism 2 32 is consistent with the moving direction of the material tray 2. Then drive the first push rod 21 to pull out of the purification warehouse 5 and close the corresponding third gate valve 12 and the second gate valve 11 movably connected between the purification warehouse 5 and the second transition warehouse 9.

[0094] A fifth vacancy detection device is installed in the second transition chamber 9. Before pushing the material tray 2 to the second conveying device of the second diverting mechanism 32, the fifth vacancy detection device transmits a signal to the control system 40 to detect whether a material tray 2 is placed on the second conveying device of the second diverting mechanism 32. The control system 40 then controls the first push rod 21 corresponding to the third gate valve 12 of the purification chamber 5 to operate. Specifically, when the fifth vacancy detection device detects that a material tray 2 is placed on the second conveying device of the second diverting mechanism 32, the control system 40 controls the first push rod 21 corresponding to the third gate valve 12 of the purification chamber 5 to not operate. When the fifth vacancy detection device detects that no material tray 2 is placed on the second conveying device of the second diverting mechanism 32, the control system 40 controls the first push rod 21 corresponding to the third gate valve 12 of the purification chamber 5 to enter the purification chamber 5 to push the material tray 2 placed on the third working section 19 at the rightmost end of the purification chamber 5 to the second conveying device of the second diverting mechanism 32 in the second transition chamber 9.

[0095] Step S43, start the forced cooling fan 25, which performs phased forced cooling according to the cooling characteristics of different materials 15, to ensure that the material 15 meets the furnace discharge condition when it moves to the rightmost end of the cooling bin 6.

[0096] Step S44: The bottom plate 211 of the second steering mechanism 32 is caused to act on the second conveying device of the second steering mechanism 32, and the lifting mechanism of the second steering mechanism 32 is activated to lift the material tray 2 placed on the second conveying device of the second steering mechanism 32. After that, the reversing mechanism is activated to change the conveying direction of the second conveying device of the second steering mechanism 32, aligning the conveying direction of the second conveying device of the second steering mechanism 32 with the conveying direction of the fourth conveying member of the fourth working section 20 in the cooling chamber 6. After adjusting the conveying direction of the second conveying device of the second steering mechanism 32, the lifting mechanism is activated to lower the lifted material tray 2 and restore it to its original position, aligning the upper surface of the second conveying device of the second steering mechanism 32 with the upper surface of the fourth conveying member.

[0097] Step S45, then open the fourth gate valve 13 movably connected to the second transition chamber 9 and the second gate valve 11 movably connected between the second transition chamber 9 and the cooling chamber 6, drive the second push rod 22 corresponding to the fourth gate valve 13 and act on the material tray 2, push the material tray 2 to move to the fourth working part 20 at the leftmost end of the cooling chamber 6, and then the second push rod 22 pulls out the second transition chamber 9 and moves it to the initial position, and finally close the fourth gate valve 13 and the second gate valve 11.

[0098] A sixth vacancy detection device is installed in the cooling chamber 6. Before pushing the material tray 2 into the cooling chamber 6, the sixth vacancy detection device transmits a signal to the control system 40 to detect whether a material tray 2 is placed on the fourth working section 20 at the rightmost end of the cooling chamber 6. The control system 40 then controls the second push rod 22 corresponding to the fourth gate valve 13 of the second transition chamber 9 to operate. Specifically, when the sixth vacancy detection device detects that a material tray 2 is placed on the fourth working section 20 at the rightmost end of the cooling chamber 6, the control system 40 controls the second push rod 22 corresponding to the fourth gate valve 13 of the second transition chamber 9 to not operate. When the sixth vacancy detection device detects that no material tray 2 is placed on the fourth working section 20 at the rightmost end of the cooling chamber 6, the control system 40 controls the second push rod 22 corresponding to the fourth gate valve 13 of the second transition chamber 9 to enter the second transition chamber 9 to push the material tray 2 placed in the second transition chamber 9 to be transferred to the fourth working section 20 at the leftmost end of the cooling chamber 6. Step S46: Repeat the above steps S41 to S45 to push a plurality of fourth materials to be cooled to the cooling bin 6 for cooling.

[0099] When executing step S43 and step S44, the order of the two can be interchanged.

[0100] Step S5, opening the first gate valve 10 provided between the cooling bin 6 and the discharge bin 7, sending the cooled fourth material into the discharge bin 7 and then taking it out, specifically comprises the following steps:

[0101] Step S51: Start the first steering mechanism 24 33. The bottom plate 211 of the first steering mechanism 24 33 acts on the first conveying device of the first steering mechanism 24 33 to adjust the conveying direction of the first conveying device so that the conveying direction of the first conveying device is consistent with the direction in which the material tray 2 moves toward the discharge bin 7.

[0102] Step S52, open the first gate valve 10 movably connected between the cooling bin 6 and the discharge bin 7 and the valve on the cooling bin 6, start the third push rod 39 corresponding to the valve on the cooling bin 6 to push the material tray 2 on the first transmission device of the first steering mechanism 43 located at the rightmost end of the cooling bin 6, and push the material tray 2 into the discharge bin 7, then drive the third push rod 39 to pull out the cooling bin 6 and close the first gate valve 10 movably connected between the cooling bin 6 and the discharge bin 7 and the valve of the cooling bin 6.

[0103] A seventh vacancy detection device is installed in the discharge bin 7. Before pushing the material tray 2 into the discharge bin 7, the seventh vacancy detection device transmits the signal collected to the control system 40 to detect whether the material tray 2 is placed in the discharge bin 7. The control system 40 controls the third push rod 39 corresponding to the valve of the cooling bin 6 to operate. Specifically, when the seventh vacancy detection device detects that the material tray 2 is placed in the discharge bin 7, the control system 40 controls the third push rod 39 corresponding to the valve of the cooling bin 6 to not operate after receiving the signal. When the seventh vacancy detection device detects that there is no material tray 2 in the discharge bin 7, the control system 40 controls the third push rod 39 corresponding to the valve of the cooling bin 6 to enter the discharge bin 7 after receiving the signal, and pushes the material tray 2 on the first transmission device of the first steering mechanism 43 at the rightmost end of the cooling bin 6 to be transferred into the discharge bin 7.

[0104] Step S53: Repeat the above steps S51 to S52 to push a plurality of carbonized, graphitized, and purified fourth materials to the discharge bin 7 and then take them out.

[0105] Step S6: Repeat the above steps S1 to S5 to achieve continuous production of carbonization, graphitization and purification of the first material.

[0106] In this embodiment, the rotation angle of the first steering mechanism 38 is 90°, and those skilled in the art can adjust the rotation angle according to the specific implementation environment.

[0107] The first vacancy detection device, the second vacancy detection device, the third vacancy detection device, the fourth vacancy detection device, the fifth vacancy detection device, the sixth vacancy detection device and the seventh vacancy detection device in this embodiment can adopt the same type of vacancy detection device. There is no restriction on the specifications and models of the vacancy detection device, as long as it can collect the signal of whether there is a material tray 2 at the position to be detected.
