Description

Technical Field

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

[0002] Hard carbon felt is widely used as a heat insulation material 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 forming, curing, carbonization, graphitization and purification. At present, the carbonization of hard carbon felt requires putting the hard carbon felt into an intermittent carbonization furnace, heating up, keeping warm and cooling down, and then taking it out of the intermittent carbonization furnace, and then entering an intermittent graphitization furnace, which also requires heating up, keeping warm and cooling down and then taking it out of the graphitization furnace. If high-quality hard carbon felt is required, the hard carbon felt also needs to be put into an intermittent purification furnace for further purification. This results in long production time, high production cost, high production energy consumption, and high product price of hard carbon felt, seriously restricting the development of the industry.

[0003] Based on this, the Chinese utility model patent (CN203699918U) proposes a carbonization graphitization continuous high-temperature furnace, which includes a feeding chamber, a graphite partition door, a boat pushing mechanism, a carbonization cavity, a transition chamber, a graphitization cavity and a discharging chamber. The carbonization cavity and the graphitization cavity are connected together through the transition chamber, so that the graphite raw material after carbonization directly enters the graphitization high-temperature furnace through the transition chamber, thus realizing continuous production of carbonization and graphitization. However, its carbonization cavity and graphitization cavity are separately arranged, resulting in large equipment floor area and high manufacturing cost. Summary of the Invention

[0028] The carbonization and graphitization chamber 4 includes a carbonization zone and a graphitization zone, which are partitioned. Integrating the carbonization zone and the graphitization zone into the carbonization and graphitization chamber 4 can save manufacturing costs and reduce the floor area. Taking PAN-based rigid carbon felt as an example, since non-carbon elements in PAN-based fibers are discharged in the form of gases, such as ammonia, nitrogen, and hydrogen, during high-temperature carbonization of PAN-based rigid carbon felt, and there are also some resin glue substances in PAN-based fibers that produce a large amount of tar and gas at high temperatures, forming liquid tar in the vacuum pipeline. The main function of the PAN-based rigid carbon felt during high-temperature graphitization in the graphitization zone is 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 into an ordered graphite structure, and only a small amount of gas is discharged during the graphitization process. Therefore, the feeding bin 3 and the carbonization zone of the carbonization and graphitization chamber 4 are connected to the first vacuum pump 1 through the cyclone filtration device 16 installed in the extraction pipeline, which is used to quickly condense the tar generated during the carbonization process into a liquid and store it in the liquid accumulation tank of the cyclone filtration device 16, preventing the tar from entering the interior of the first vacuum pump 1 and avoiding the impurities discharged during carbonization from contaminating the material 15 in the graphitization zone.

[0043] A fourth plug valve 13 is also movably connected to the transition bin. The fourth plug valve 13 corresponds to the second push rod 22 one by one. When it is necessary to extend the second push rod 22 into the transition bin to push the material 15, the fourth plug valve 13 is opened. When the second push rod 22 is used to push the material 15 to the designated position, after the second push rod 22 is withdrawn from the transition bin, the fourth plug valve 13 is closed.

[0044] The first transition bin 8 and the purification bin 5 are connected to the second vacuum pump 23 through a first filter tank 24 installed in the first vacuum pipeline 26. The first vacuum pipeline 26 is connected between the first transition bin 8, the purification bin 5 and the second vacuum pump 23, that is, the first transition bin 8, the purification bin 5 and the second vacuum pump 23 are interconnected through the first vacuum pipeline 26. The second transition bin 9 and the cooling bin 6 are connected to the output end of the strong cooling fan 25 through a second filter tank 42 installed in the second vacuum pipeline 41. The vacuum pipeline 26 is connected between the second transition bin 9, the cooling bin 6 and the output end of the strong cooling fan 25, that is, the second transition bin 9, the cooling bin 6 and the output end of the strong cooling fan 25 are interconnected through the second vacuum pipeline 41.

[0045] In this embodiment, the material 15 uses PAN-based hard carbon felt.

[0046] A continuous carbonization, graphitization, and purification method provided by the present invention uses the above-mentioned continuous carbonization, graphitization, and purification equipment, including the following steps: Step S1: Place the first material to be carbonized, graphitized, and purified into the feeding bin 3, and perform vacuum pumping on the feeding bin 3 through the first vacuum pump 1; Specifically, place the tray 2 filled with the first material to be carbonized, graphitized, and purified into the feeding bin 3. After closing the feeding bin 3, start the first vacuum pump 1 to perform vacuum pumping on the feeding bin 3.

[0047] Step S2: Open the first plug valve 10 between the feeding bin 3 and the carbonization and graphitization bin 4, send the first material into the carbonization zone of the carbonization and graphitization bin 4 for carbonization treatment to obtain the second material, and then the first transmission member and the second transmission member cooperate with each other to send the second material into the graphitization zone of the carbonization and graphitization bin 4 for graphitization treatment to obtain the third material. Specifically, it includes the following steps: Step S21: Open the first plug valve 10 movably connected between the feeding bin 3 and the carbonization and graphitization bin 4 and the valve of the feeding bin 3, drive the third push rod 39 corresponding to the valve of the feeding bin 3. The third push rod 39 is movably connected to the feeding bin 3 and acts on the tray 2 to push the tray 2 into the leftmost first working part 17 in the carbonization zone. At this time, the transmission direction of the leftmost first working part 17 in the carbonization zone is the same as the movement direction of the tray 2. Then, drive the third push rod 39 corresponding to the valve of the feeding bin 3 to withdraw from the carbonization and graphitization bin 4 and move to the initial position, and close the first plug valve 10 and the valve of the feeding bin 3.

[0048] Before pushing the tray 2 into the leftmost first working part 17 in the carbonization zone, the first vacancy detection device transmits the signal of whether there is a tray 2 placed on the first working part 17 collected to the control system 40, and the control system 40 controls the action of the third push rod 39 corresponding to the valve of the feeding bin 3. Specifically, when the first vacancy detection device detects that there is a tray 2 placed on the leftmost first working part 17 in the carbonization zone, the control system 40 receives this signal and controls the third push rod 39 corresponding to the valve of the feeding bin 3 not to act. When the first vacancy detection device detects that there is no tray 2 placed on the leftmost first working part 17 in the carbonization zone, the control system 40 receives this signal and controls the third push rod 39 corresponding to the valve of the feeding bin 3 to enter the feeding bin 3 and push the tray 2 onto the leftmost first working part 17 in the carbonization zone.

[0049] Step S22: Start the first steering mechanism 28. The bottom plate 211 of the first steering mechanism 28 acts on the first transmission device of the first steering mechanism 28 on the first working part 17. The lifting mechanism of the first steering mechanism 28 lifts the material tray 2 placed on the first transmission device of the first steering mechanism 28 and then starts the reversing mechanism to change the transmission direction of the first transmission device of the first steering mechanism 28, so that the transmission direction of the first transmission device of the first steering mechanism 28 is consistent with the transmission direction of the first transmission member, that is, the rotation directions of the multiple graphite rollers 27 on the first transmission device of the first steering mechanism 28 are consistent with the rotation directions of the multiple graphite rollers 27 on the first transmission member installed in the carbonization area. After adjusting the transmission direction of the first transmission device on the first steering mechanism 28, start the lifting mechanism to return the lifted material tray 2 to its original position, that is, make the first transmission device on the first steering mechanism 28 and the first transmission member in the same plane.

[0050] Step S23: Open the third plug valve 12 movably connected to the left side of the carbonization area of the carbonization and graphitization chamber 4, drive the first push rod 21 corresponding to the third plug valve 12 and act it on the material tray 2, push the material tray 2 to move to the next first working part 17, then the first push rod 21 is withdrawn from the carbonization and graphitization chamber 4 and moves to the initial position, and close the third plug valve 12.

[0051] Step S24: Repeat steps S21 to S23. When the second material tray 2 is pushed to the first working part 17 where the previous material tray 2 is located, the first material tray 2 is pushed to the next first working part 17. In this way, multiple material trays 2 filled with the first materials to be carbonized, graphitized, and purified can be moved to the carbonization area for carbonization operation.

[0052] Since the carbonization area and the graphitization area are integrated in the carbonization and graphitization chamber 4, the structures of the corresponding first transmission member and the second transmission member are the same, and the upper surfaces of the first transmission member and the second transmission member are in the same plane. Repeating steps S21 to S24 can push the carbonized first material to the graphitization area for graphitization operation, thereby obtaining the third material.

[0053] Before pushing the tray 2 to the next first working part 17, the second vacancy detection device transmits the signal of whether there is a tray 2 placed on the second working part 18 at the rightmost end of the graphitization area to the control system 40, and the control system 40 controls the action of the first push rod 21 corresponding to the third sluice valve 12 in the carbonization area. Specifically, when the second vacancy detection device detects that there is a tray 2 placed on the second working part 18 at the rightmost end of the graphitization area, the control system 40 receives this signal and controls the first push rod 21 not to act. When the second vacancy detection device detects that there is no tray 2 on the second working part 18 at the rightmost end of the graphitization area, the control system 40 receives this signal and controls the first push rod 21 corresponding to the third sluice valve 12 in the carbonization area to enter the carbonization area to push the tray 2 to be transmitted to the next first working part 17.

[0054] Step S3: Open the second sluice valve 11 provided between the carbonization and graphitization bin 4 and the first transition bin 8 and the second sluice valve 11 provided between the first transition bin 8 and the purification bin 5, and send the third material into the purification bin 5 for purification treatment to obtain the fourth material. Specifically, it includes the following steps: Step S31: Start the second steering mechanism 29. The bottom plate 211 of the second steering mechanism 29 acts on the first transmission device of the second steering mechanism 29 on the second working part 18 at the rightmost end of the graphitization area to adjust its transmission direction to be consistent with the transmission direction of the second transmission device of the first steering mechanism 30 located in the first transition bin 8.

[0055] Step S32: After opening the second sluice valve 11 movably connected between the carbonization and graphitization bin 4 and the first transition bin 8 and the third sluice valve 12 movably connected to the graphitization area end of the carbonization and graphitization bin 4, drive the first push rod 21 corresponding to the third sluice valve 12 to push the tray 2 located at the second working part 18 at the rightmost end of the graphitization area onto the second transmission device of the first steering mechanism 30. At this time, the transmission direction of the second transmission device of the first steering mechanism 30 is consistent with the moving direction of the tray 2. Then drive the first push rod 21 to withdraw from the carbonization and graphitization bin 4 and close the corresponding third sluice valve 12 and the second sluice valve 11 movably connected between the carbonization and graphitization bin 4 and the first transition bin 8.

[0056] A third vacant position detecting device is installed in the first transition bin 8. Before the material tray 2 is pushed to the second transmission device of the first second steering mechanism 30, the third vacant position detecting device transmits the signal of whether the material tray 2 is placed on the second transmission device of the first second steering mechanism 30 to the control system 40, and the control system 40 controls the action of the first push rod 21 corresponding to the third shutter valve 12 in the graphitization area. Specifically, when the third vacant position detecting device detects that the material tray 2 is placed on the second transmission device of the first second steering mechanism 30, the control system 40 controls the first push rod 21 corresponding to the third shutter valve 12 in the graphitization area not to act after receiving the signal. When the third vacant position detecting device detects that there is no material tray 2 on the second transmission device of the first second steering mechanism 30, the control system 40 controls the first push rod 21 corresponding to the third shutter valve 12 in the graphitization area to enter the graphitization area to push the material tray 2 placed at the second working part 18 at the rightmost end of the graphitization area to be transmitted to the second transmission device of the first second steering mechanism 30 in the first transition bin 8.

[0057] Step S33: Start the second vacuum pump 23 to pump out the gas entering the first transition bin 8 from the carbonization and graphitization bin 4 to prevent the gas from entering the purification bin 5.

[0058] Step S34: Make the bottom plate 211 of the first second steering mechanism 30 act on the second transmission device of the first second steering mechanism 30 in the first transition bin 8. Start the lifting mechanism of the first second steering mechanism 30, lift the material tray 2 placed on the second transmission device of the first second steering mechanism 30, and then start its reversing mechanism to change the transmission direction of the second transmission device of the first second steering mechanism 30, that is, to make the transmission direction of the second transmission device of the first second steering mechanism 30 consistent with the transmission direction of the third transmission part of the third working part 19 in the purification bin 5. After adjusting the transmission direction of the second transmission device of the first second steering mechanism 30, start the lifting mechanism to lower the lifted material tray 2 back to the original position, that is, make the upper surface of the second transmission device of the first second steering mechanism 30 and the upper surface of the third transmission part be in the same plane.

[0059] Step S35: Open the fourth shutter valve 13 movably connected to the first transition bin 8 and the second shutter valve 11 movably connected between the first transition bin 8 and the purification bin 5. Drive the second push rod 22 corresponding to the fourth shutter valve 13 and act on the material tray 2 to push the material tray 2 to move to the third working part 19 at the leftmost end in the purification bin 5. Then, the second push rod 22 is withdrawn from the first transition bin 8 and moved to the initial position. Finally, close the fourth shutter valve 13 and the second shutter valve 11.

[0060] A fourth vacant position detection device is installed in the purification bin 5. Before the tray 2 is pushed into the purification bin 5, the fourth vacant position detection device transmits the signal of whether there is a tray 2 placed on the third working part 19 at the rightmost end in the purification bin 5 to the control system 40, and the control system 40 controls the action of the second push rod 22 corresponding to the fourth plug valve 13 of the first transition bin 8. Specifically, when the fourth vacant position detection device detects that there is a tray 2 placed on the first transmission device of the first steering mechanism three 31 in the purification bin 5, after the control system 40 receives this signal, it controls the second push rod 22 corresponding to the fourth plug valve 13 of the first transition bin 8 not to act. When the fourth vacant position detection device detects that there is no tray 2 on the third working part 19 at the rightmost end in the purification bin 5, after the control system 40 receives this signal, it controls the second push rod 22 corresponding to the fourth plug valve 13 of the first transition bin 8 to enter the first transition bin 8 to push the tray 2 placed in the first transition bin 8 to be transmitted to the third working part 19 at the leftmost end in the purification bin 5.

[0061] Step S36: Repeat steps S31 to S35, and multiple third materials to be purified can be pushed into the purification bin 5 for purification operations.

[0062] Among them, when performing step S33 and step S34, the order of the two can be interchanged.

[0063] Step S4: Open the second plug valve 11 provided between the purification bin 5 and the second transition bin 9 and the second plug valve 11 provided between the second transition bin 9 and the cooling bin 6, and send the fourth material into the cooling bin 6 for cooling treatment. The specific steps include: 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 bin 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 bin 9.

[0064] Step S42: After opening the second plug valve 11 movably connected between the purification bin 5 and the second transition bin 9 and the third plug valve 12 movably connected to the purification bin 5, drive the first push rod 21 corresponding to the third plug valve 12 to push the tray 2 at the third working part 19 at the rightmost end of the purification bin 5 to the second transmission device of the second steering mechanism two 32 in the second transition bin 9. At this time, the transmission direction of the second transmission device of the second steering mechanism two 32 is consistent with the moving direction of the tray 2. Then drive the first push rod 21 to withdraw from the purification bin 5 and close the third plug valve 12 corresponding to it and the second plug valve 11 movably connected between the purification bin 5 and the second transition bin 9.

[0065] A fifth vacancy detection device is installed in the second transition bin 9. Before the tray 2 is pushed to the second transmission device of the second steering mechanism 32, the fifth vacancy detection device transmits the signal collected on whether there is a tray 2 placed on the second transmission device of the second steering mechanism 32 to the control system 40, and the control system 40 controls the action of the first push rod 21 corresponding to the third plug valve 12 of the purification bin 5. Specifically, when the fifth vacancy detection device detects that there is a tray 2 placed on the second transmission device of the second steering mechanism 32, the control system 40 receives this signal and controls the first push rod 21 corresponding to the third plug valve 12 of the purification bin 5 not to act. When the fifth vacancy detection device detects that there is no tray 2 on the second transmission device of the second steering mechanism 32, the control system 40 receives this signal and controls the first push rod 21 corresponding to the third plug valve 12 of the purification bin 5 to enter the purification bin 5 to push the tray 2 placed at the rightmost end of the purification bin 5 to the second transmission device of the second steering mechanism 32 in the second transition bin 9.

[0066] Step S43: Start the strong cooling fan 25. The strong cooling fan 25 performs staged forced cooling according to the cooling characteristics of different materials 15 to ensure that the material 15 meets the furnace-out conditions when it moves to the rightmost end of the cooling bin 6.

[0067] Step S44: Make the bottom plate 211 of the second steering mechanism 32 act on the second transmission device of the second steering mechanism 32. Start the lifting mechanism of the second steering mechanism 32, lift the tray 2 placed on the second transmission device of the second steering mechanism 32, and then start the reversing mechanism to change the transmission direction of the second transmission device of the second steering mechanism 32, that is, to make the transmission direction of the second transmission device of the second steering mechanism 32 consistent with the transmission direction of the fourth transmission member of the fourth working part 20 in the cooling bin 6. After adjusting the transmission direction of the second transmission device of the second steering mechanism 32, start the lifting mechanism to lower the lifted tray 2 and restore it to the original position, that is, make the upper surface of the second transmission device of the second steering mechanism 32 and the upper surface of the fourth transmission member be in the same plane.

[0068] Step S45: Then open the fourth plug valve 13 movably connected to the second transition bin 9 and the second plug valve 11 movably connected between the second transition bin 9 and the cooling bin 6. Drive the second push rod 22 corresponding to the fourth plug valve 13 and act on the tray 2, push the tray 2 to move to the fourth working part 20 at the leftmost end in the cooling bin 6, then the second push rod 22 is withdrawn from the second transition bin 9 and moves to the initial position, and finally close the fourth plug valve 13 and the second plug valve 11.

[0069] A sixth vacant position detection device is installed in the temperature reduction bin 6. Before the tray 2 is pushed into the temperature reduction bin 6, the sixth vacant position detection device transmits the signal of whether there is a tray 2 placed on the fourth working part 20 at the rightmost end in the temperature reduction bin 6 to the control system 40, and the control system 40 controls the second push rod 22 corresponding to the fourth plug valve 13 of the second transition bin 9 to act. Specifically, when the sixth vacant position detection device detects that there is a tray 2 placed on the fourth working part 20 at the rightmost end in the temperature reduction bin 6, the control system 40 controls the second push rod 22 corresponding to the fourth plug valve 13 of the second transition bin 9 not to act after receiving this signal. When the sixth vacant position detection device detects that there is no tray 2 on the fourth working part 20 at the rightmost end in the temperature reduction bin 6, the control system 40 controls the second push rod 22 corresponding to the fourth plug valve 13 of the second transition bin 9 to enter the second transition bin 9 to push the tray 2 placed in the second transition bin 9 to be transmitted to the fourth working part 20 at the leftmost end in the temperature reduction bin 6. Step S46: Repeat the above steps S41 to S45, and multiple fourth materials to be cooled can be pushed into the temperature reduction bin 6 for cooling operation.

[0070] Among them, when performing step S43 and step S44, the order of the two can be interchanged.

[0071] Step S5: Open the first plug valve 10 provided between the temperature reduction bin 6 and the discharge bin 7, send the cooled fourth material into the discharge bin 7 and then take it out, which specifically includes the following steps: Step S51: Start the fourth first steering mechanism 33. The bottom plate 211 of the fourth first steering mechanism 33 acts on the first transmission device of the fourth first steering mechanism 33 to adjust the transmission direction of the first transmission device so that the transmission direction of the first transmission device is consistent with the moving direction of the tray 2 towards the discharge bin 7. Step S52: Open the first plug valve 10 movably connected between the temperature reduction bin 6 and the discharge bin 7 and the valve on the temperature reduction bin 6, start the third push rod 39 corresponding to the valve on the temperature reduction bin 6 to push the tray 2 on the first transmission device of the fourth first steering mechanism 33 at the rightmost end of the temperature reduction bin 6, push the tray 2 into the discharge bin 7, and then drive the third push rod 39 to withdraw from the temperature reduction bin 6 and then close the first plug valve 10 movably connected between the temperature reduction bin 6 and the discharge bin 7 and the valve of the temperature reduction bin 6.

[0072] A seventh vacancy detection device is installed in the discharge bin 7. Before the tray 2 is pushed into the discharge bin 7, the seventh vacancy detection device transmits the signal of whether there is a tray 2 placed in the discharge bin 7 collected to the control system 40, and the control system 40 controls the action of the third push rod 39 corresponding to the valve of the cooling bin 6. Specifically, when the seventh vacancy detection device detects that there is a tray 2 placed in the discharge bin 7, after receiving this signal, the control system 40 controls the third push rod 39 corresponding to the valve of the cooling bin 6 not to act. When the seventh vacancy detection device detects that there is no tray 2 in the discharge bin 7, after receiving this signal, 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 to push the tray 2 on the first transmission device of the first steering mechanism four 33 placed at the rightmost end of the cooling bin 6 and transmit it into the discharge bin 7.

[0073] Step S53: Repeat the above steps S51 to S52, and multiple carbonized, graphitized, and purified fourth materials can be pushed into the discharge bin 7 and then taken out.

[0074] Step S6: Repeat the above steps S1 to S5 to realize the continuous production of carbonization, graphitization, and purification of the first material.

[0075] The rotation angle of the steering mechanism 38 in this embodiment is 90°, and those skilled in the art can adjust the rotation angle according to the specific implementation environment.

[0076] 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. The specifications and models of the vacancy detection device are not limited here, as long as it can collect the signal of whether there is a tray 2 at the position to be detected.
