Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of carbonization furnaces, in particular to vertical continuous high-temperature carbonization furnace equipment. Background Art
[0002] Carbonization furnace is a device that converts organic matter into carbon by heating graphite at high temperature. Its working principle mainly includes four processes: preheating, heating, carbonization and cooling.
[0003] Before the high-temperature carbonization furnace starts working, the furnace needs to be preheated first. Preheating is to improve work efficiency and protect equipment. By controlling the heating elements, the temperature inside the furnace is gradually raised to the set working temperature. After the preheating is completed, organic matter (such as wood, fruit shells, etc.) is placed in the furnace. The organic matter is heated by high-temperature graphite or other heating elements. As the heating proceeds, the organic matter gradually turns into carbon. Under high temperature conditions, the organic matter will decompose to produce gas and liquid, while releasing a large amount of heat. As the heating proceeds, the organic matter gradually turns into carbon. Under high temperature conditions, the carbon atoms in the organic matter gradually arrange into a chain structure to form a dense carbon layer. After carbonization is completed, the temperature in the furnace needs to be gradually lowered so that the carbon layer will not be too fragile. By controlling the heating elements or other cooling equipment, the temperature inside the furnace is gradually lowered.
[0004] However, the existing carbonization furnace still has shortcomings:
[0005] 1. Material particles are usually placed directly in a graphite crucible for heating. Since the graphite crucible has a certain volume, if the material particles are piled up in the graphite crucible for heating, the material particles will be heated unevenly, affecting the heating and carbonization effect of the material particles.
[0006] 2. Waste gas will be generated during the heating and carbonization process of the material particles. The waste gas usually rises directly and is discharged from the exhaust port at the upper end of the furnace body. During the discharge process, the waste gas will carry the material with it.

[0031] like Figure 1-8 As shown, a vertical continuous high-temperature carbonization furnace device includes a frame steel platform 1 and a temperature control system. The upper end of the frame steel platform 1 is provided with a carbonization furnace body. The carbonization furnace body includes a feeding partition 4, a heating partition 3, and a cooling partition 5, each of which can set the internal temperature separately. The carbonization furnace body is provided with a plurality of graphite crucibles 8 that are stacked and can be driven synchronously. A cylindrical turntable 25 is provided in the middle of the graphite crucible 8. A multi-faceted graphite crucible that passes through the cylindrical turntable 25 is fixed on the frame steel platform 1. Shaft 16, the graphite crucible 8 is respectively provided with a graphite climbing claw body 17 fixedly connected to the multi-faceted graphite shaft 16, the bottom of the graphite crucible 8 is provided with a leakage hole 24 corresponding to the graphite climbing claw body 17, and the leakage holes 24 on the stacked graphite crucibles 8 are staggered by 120° between layers, and the lower end of the frame steel platform 1 is provided with a discharge barrel 11 connected to the carbonization furnace body, and the discharge barrel 11 is provided with a discharge valve port 28, and the temperature control system is used to control the temperature and heat the material particles in the feeding compartment 4 and the heating compartment 3.
[0032] When the present invention is in use, the feeding partition 4, the heating partition 3 and the cooling partition 5 in the furnace of the carbonization furnace body are preheated and heated respectively. Preheating can improve work efficiency, and the material particles are added to the graphite crucible 8 of the feeding partition 4 of the carbonization furnace body. At the same time, the superimposed graphite crucibles 8 are controlled to rotate synchronously. Since the multi-faceted graphite shaft 16 fixes the graphite climbing claws 17 in the graphite crucible 8, when the graphite crucible 8 is rotated, the material flow inside the graphite crucible 8 performs a lateral rotation motion, and the continuously added material flow is guided to realize the circular motion of the material flow in the horizontal plane of the superimposed graphite crucible 8. Under the action of the graphite climbing claws 17, the material flow moves in a prescribed circle. The leakage holes 24 in the graphite crucible 8 at the corner position flow into the lower layer, and the movement of the material flow realizes the collision, friction and extrusion between the material particles, and the material is heated evenly. The material is heated in the pre-carbonized graphite crucible 8 superimposed in the feeding section 4 and simultaneously rotates sideways layer by layer. The material is heated in the high-temperature carbonized graphite crucible 8 superimposed in the heating section 3 and simultaneously rotates sideways layer by layer. The material moves to the graphite crucible 8 superimposed in the cooling section 5 and simultaneously rotates sideways layer by layer, and finally rolls into the discharge barrel 11, and the discharge is controlled by the discharge valve 28. The leakage holes 24 in different graphite crucibles 8 are staggered by 120° between layers, which can form a spiral climb for the exhaust gas to the exhaust port 7 on the top of the furnace without easily carrying the material to escape upward.
[0033] The feeding compartment 4, the heating compartment 3 and the cooling compartment 5 are all provided with an electric heating field 27, and the electric heating field 27 adopts a silicon molybdenum rod electric heating field 27. The upper end of the carbonization furnace body is provided with an electric connector 29 electrically connected to the electric heating field 27.
[0034] like Figure 2 As shown, the electric heating field 27 is energized through the electric connector 29, and the silicon molybdenum rod electric heating field 27 is used to heat the feeding compartment 4, the heating compartment 3 and the cooling compartment 5, and the internal temperatures of the feeding compartment 4, the heating compartment 3 and the cooling compartment 5 can be controlled separately to achieve continuous production. The material is gradually heated, continuously heated and continuously cooled through different temperature sections, and a better controllable temperature control curve is achieved for the powder fiber.
[0035] The frame steel platform 1 is provided with a rotating table 18 for transmission, and a second gear 9 is provided on the rotating table 18. The second gear 9 is engaged with a first gear 10 that is rotatably connected to the frame steel platform 1. A rotating column 22 is provided on the first gear 10. The lower end of the frame steel platform 1 is respectively provided with a motor 12 and a reducer 14. The output end of the motor 12 is fixedly connected to the first pulley 13, and the input end of the reducer 14 is fixedly connected to the second pulley 15. The first pulley 13 is connected to the second pulley 15 by belts, and the output end of the reducer 14 is connected to the rotating column 22.
[0036] like Figure 2-5As shown, the motor 12 drives the first pulley 13 to rotate, the first pulley 13 drives the second pulley 15 to rotate, the second pulley 15 drives the reducer 14 to work, the output end of the reducer 14 drives the rotating column 22 to rotate, the rotating column 22 drives the first gear 10 to rotate, the first gear 10 drives the second gear 9 to rotate, and the second gear 9 drives the rotating table 18 to rotate. Since the graphite crucible 8 is limited and set on the rotating table 18, the rotating table 18 is used to synchronously drive the graphite crucible 8.
[0037] A limiting groove 20 is provided on the circumference of the upper end of the graphite crucible 8 , and a limiting end plate 21 adapted to the limiting groove 20 is provided on the circumference of the lower end of the graphite crucible 8 .
[0038] like Figure 6 and 7 As shown, the limiting end plate 21 at the lower end of the upper graphite crucible 8 can be sealed and inserted into the limiting groove 20 of the lower graphite crucible 8 to achieve the stacking of the graphite crucibles 8. Due to the arrangement of the limiting end plate 21 and the limiting groove 20, the graphite crucible 8 arranged on the rotating table 18 can synchronously drive the stacked graphite crucible 8 at the upper end to rotate.
[0039] The upper circumference of the rotating platform 18 is provided with a receiving groove adapted to the limiting end plate 21 .
[0040] like Figure 5 As shown, the limiting end plate 21 at the lower end of the graphite crucible 8 can be placed in the receiving groove on the rotating table 18, and the rotating table 18 is used to rotate the graphite crucible 8.
[0041] The graphite climbing claw body 17 includes a plurality of waist-shaped leakage holes 26 that are evenly arranged and staggered with the leakage holes 24 . The graphite climbing claw body 17 also includes climbing claws 23 that are attached to the bottom of the graphite crucible 8 and correspond to the leakage holes 24 .
[0042] like Figure 8 As shown, the waist-shaped leakage holes 26 are set at 120° on the graphite climbing claw body 17, and the leakage holes 24 on the graphite crucible 8 are staggered 120° between layers to ensure that the material particles fall into the graphite crucible 8 through the waist-shaped leakage holes 26 during the process of falling from the leakage holes 24 to the next graphite crucible 8. During the rotation of the graphite crucible 8, the climbing claws 23 use the graphite crucible 8 to make the material in the graphite crucible 8 fall from the leakage holes 24 after the graphite crucible 8 rotates sideways at a certain angle.
[0043] The discharge valve port 28 adopts a superimposed pneumatic semi-ball valve. The upper end of the carbonization furnace body is provided with a filling port 6 corresponding to the graphite crucible 8. One end of the filling port 6 is provided with a furnace top exhaust port 7 communicating with the carbonization furnace body.
[0044] like Figure 2As shown, the discharge valve port 28 adopts a superimposed pneumatic semi-ball valve, which is used to control the discharge of materials. The materials are added to the graphite crucible 8 through the injection port 6 on the top of the furnace. Exhaust gas is generated during the carbonization process of the materials, and the exhaust gas can be discharged upward through the leakage holes 24. Since the leakage holes 24 in different graphite crucibles 8 are staggered by 120 degrees between layers, the exhaust gas can be spirally climbed to the exhaust port 7 on the top of the furnace and is not easy to escape upward with the materials.
[0045] A plurality of supporting legs 2 are evenly arranged at the lower end of the frame steel platform 1 .
[0046] like Figure 1 As shown, the support legs 2 support and fix the frame steel platform 1.
[0047] The lower end of the polygonal graphite shaft 16 is provided with a fixing rod 19 fixedly connected to the frame steel platform 1, and the fixing rod 19 is high temperature resistant and has a smooth surface.
[0048] like Figure 5 As shown, the polygonal graphite shaft 16 is fixed to the inner wall of the frame steel platform 1 using a fixing rod 19 . The smooth surface of the fixing rod 19 can prevent the material from stagnating on the fixing rod 19 .
[0049] The temperature control system is used to obtain key parameters of the material particles, wherein the key parameters include volume, density, specific heat capacity and initial temperature of the material, and the mass is obtained based on the volume and density. The temperature control system obtains the initial power based on the initial temperature of the material. The temperature control system is also used to obtain the heat loss of the carbonization furnace body, the heat conduction efficiency, the target temperature at the end of the feeding interval 4 and the preheating time, and calculate the material preheating power change index based on the heat conduction efficiency, initial power, preheating time, target temperature, mass, specific heat capacity and initial temperature of the material, wherein the calculation formula is: Among them, Y(XP) represents the material preheating power change index, W(ZL) represents the mass, W(BR) represents the specific heat capacity, M(WD) represents the target temperature, C(WD) represents the initial temperature of the material, Y(RC) represents the preheating time, C(GL) represents the initial power, and R(CD) represents the heat conduction efficiency. The temperature control system adjusts the heating temperature of the feeding compartment 4 in real time according to the material preheating power change index.
[0050] As described above, the present invention obtains the key parameters of the material particles, such as volume, density, specific heat capacity and initial temperature of the material, through the temperature control system, and obtains the mass based on the volume and density. The temperature control system obtains the initial power, the heat loss of the carbonization furnace body, the heat conduction efficiency, the target temperature at the end of the feeding interval and the preheating time through the initial temperature of the material, and calculates the material preheating power change index based on the heat conduction efficiency, initial power, preheating time, target temperature, mass, specific heat capacity and initial temperature of the material. The key parameters of the material, such as volume, density, specific heat capacity and initial temperature, are obtained through the real-time temperature control system, and the heating process of the material can be dynamically adjusted to ensure that the temperature of each batch of materials is maintained constant during the processing process. It avoids the quality instability problem caused by temperature fluctuation or uneven heat transfer in traditional methods. The material mass calculated by using the initial temperature, specific heat capacity and density of the material, combined with real-time temperature control to adjust the power, can achieve precise heating, reducing the quality difference that may be caused by uneven heating, thereby improving the production consistency of the product. By obtaining the initial state of the material in real time (such as temperature, mass, specific heat capacity, etc.), the system can accurately calculate the required initial power and adjust the power output according to the properties of the material. This precise power control helps to avoid excessive energy waste and improve energy utilization efficiency. By considering the heat loss and heat conduction efficiency of the carbonization furnace body, the temperature control system can During the preheating process, energy distribution is optimized to reduce unnecessary heat loss, thereby reducing energy costs. By combining parameters such as target temperature, initial temperature, specific heat capacity, mass and preheating time, the system can accurately calculate the required preheating time and adjust the heating power in real time, which can effectively avoid the problem of overheating or insufficient heating, improve the efficiency of the preheating process, and save time. By calculating the material preheating power change index, the heating strategy can be dynamically adjusted to adjust the heat input according to the actual needs of different materials, thereby avoiding the inadaptability caused by the fixed power setting in the traditional system. By accurately calculating and real-time monitoring the temperature changes of the material, it can be ensured that the material is heated and carbonized. Maintaining the optimal temperature curve during production not only improves the quality of the final product, but also shortens the production cycle and improves overall production efficiency. By presetting and adjusting the target temperature, the temperature control system can prevent the material from burning or structural changes due to overheating, thereby ensuring the quality and consistency of the product. By combining temperature control with the physical properties of the material (such as density, specific heat capacity, etc.), an integrated control system is formed, which can adjust production parameters according to real-time feedback, thereby realizing intelligent management of the entire production process, solving the problems of inaccurate temperature control, energy waste and low production efficiency in the material preheating process in the existing technology, and has broad application prospects and significant economic benefits.
[0051] The temperature control system is used to obtain the radiation heat loss, thermal conductivity, convection heat transfer coefficient, heat exchange area, and temperature characteristics of the carbonization furnace body, wherein the temperature characteristics include the furnace temperature and the ambient temperature, and the conduction heat loss is obtained according to the thermal conductivity, and the convection heat loss is calculated according to the convection heat transfer coefficient, the heat exchange area, the furnace temperature, and the ambient temperature, wherein the calculation formula is: D(RS)=D(HX)*R(JM)*[L(WD)-H(WD)]; wherein D(RS) represents the convection heat loss, D(HX) represents the convection heat transfer coefficient, R(JM) represents the heat exchange area, L(WD) represents the furnace temperature, and H(WD) represents the ambient temperature. The temperature control system is also used to obtain the total heat loss according to the convection heat loss, radiation heat loss, and conduction heat loss. The temperature control system is also used to obtain the initial power, preheating time, and the heat required at the feeding interval 4, and calculate the heat conduction efficiency according to the initial power, preheating time, the required heat, and the total heat loss, wherein the calculation formula is: Among them, R(CD) represents the heat transfer efficiency, S(RL) represents the required heat, Z(RS) represents the total heat loss, Y(RC) represents the preheating time, and C(GL) represents the initial power.
[0052] As described above, the present invention obtains the radiation heat loss, thermal conductivity, convection heat transfer coefficient, heat exchange area and furnace temperature and ambient temperature in the temperature characteristics of the carbonization furnace body through the temperature control system, obtains the conduction heat loss according to the thermal conductivity, and calculates the convection heat loss according to the convection heat transfer coefficient, heat exchange area, furnace temperature and ambient temperature. The temperature control system monitors the furnace temperature and ambient temperature in real time and calculates the relevant heat losses (such as radiation heat loss, conduction heat loss and convection heat loss). The system can accurately adjust the heating power and temperature control strategy to ensure that the temperature of the material in the graphite crucible changes according to the set curve to avoid overheating or insufficient heating, thereby optimizing the heating process of the material. Due to different materials and operating conditions, the heat loss and heat conduction efficiency will be different. By obtaining heat loss data in real time, the heating strategy can be flexibly adjusted according to the material characteristics and actual working conditions to avoid uneven heating during the process. When the carbonization furnace is running at high temperature, radiation heat loss is an important source of heat loss. By Real-time monitoring and calculation of the thermal radiation characteristics of the furnace body (such as the thermal emissivity of the furnace body material) can be adjusted during the design and operation process, and radiation heat loss can be reduced through more precise heating control. Conduction heat loss is determined by the thermal conductivity of the furnace wall. Real-time measurement of the thermal conductivity of the furnace body and calculation of conduction heat loss can help optimize the furnace structure design (such as the selection of insulation materials, furnace wall temperature control, etc.), and further reduce unnecessary energy loss. Through real-time calculation of the difference between the temperature inside the furnace and the ambient temperature, the heat exchange area and the convection heat transfer coefficient, the convection heat loss can be accurately grasped, so that through reasonable airflow adjustment or insulation design, the convection heat loss can be reduced, and energy utilization efficiency can be further improved. By accurately calculating the radiation, conduction and convection heat losses, the heating power and temperature control strategy of the furnace body can be adjusted in real time to make the heating process as efficient as possible. This not only avoids energy waste caused by overheating, but also ensures that the material reaches the expected temperature with the lowest energy consumption. Excessive heat loss in a high temperature environment will aggravate the wear and aging of the furnace body.By precisely controlling the temperature and heat loss in the furnace, excessive heat is avoided from being concentrated in unnecessary places, the burden on the furnace material is reduced, and the service life of the equipment is extended. By acquiring and calculating heat loss data in real time, the temperature control system can automatically adapt to different production stages, material properties and environmental changes, and adjust the temperature control strategy. This intelligent adjustment not only improves production efficiency, but also reduces the need for manual intervention and reduces the difficulty of operation. The real-time temperature control system can ensure that the temperature in the carbonization furnace is uniform and stable, thereby ensuring that the heating process of the material in the graphite crucible is more uniform and accurate, avoiding unstable product quality caused by temperature fluctuations. The present invention obtains the total heat loss based on convection heat loss, radiation heat loss and conduction heat loss through the temperature control system. By obtaining the initial power, preheating time, and the required heat at the feeding compartment, and calculating the heat conduction efficiency based on the initial power, preheating time, required heat and total heat loss, the total heat loss (including convection, radiation and conduction heat loss) can be accurately calculated to optimize the heating process, monitor and adjust the temperature of the feeding compartment in real time, effectively reduce heat waste, and reduce the energy consumption of the carbonization furnace.For example, reasonable control of heat loss and heat conduction efficiency can ensure that the heat in the heating process is more efficiently transferred to the part that needs to be heated, rather than wasted in unnecessary places. This can improve the overall thermal efficiency of the equipment and reduce operating costs. By real-time monitoring and adjusting the temperature of the feeding section, the temperature distribution in the carbonization furnace can be more accurately controlled, thereby improving the uniformity of the carbonization process. This is crucial for high-temperature carbonization processes that require precise temperature control, especially in the high-temperature environment of the graphite crucible. Even slight changes in temperature may have a significant impact on the quality of the final product. By optimizing the temperature control strategy, overheating or uneven cooling can be avoided to ensure stable product quality. By calculating and adjusting the heat conduction efficiency, the heat loss in the furnace can be significantly reduced. In a high-temperature environment, the improvement of heat conduction efficiency means that heat energy is better transferred to the target area rather than being lost through radiation or convection. This not only improves the stability of the temperature in the furnace, but also saves energy. Real-time temperature control helps to adapt to different working conditions and flexibly adjust heat distribution. By accurately calculating the initial power, preheating time and required heat, the control of the preheating stage can be optimized to avoid over-preheating or under-preheating. Reasonable setting of preheating time and power can help speed up production, shorten production cycle and improve production efficiency. At the same time, by adjusting the feeding interval temperature in real time, production stagnation or quality problems caused by insufficient or overheating can be avoided. By realizing automatic calculation and adjustment of heat loss, heat demand and heat conduction efficiency, the dependence on manual operation can be reduced, making the operation of the vertical continuous high-temperature carbonization furnace equipment more intelligent and automated, which not only reduces human error, but also improves the reliability of the system, and avoids the problem of inaccurate heat control caused by improper operation. Therefore, the heating process of the vertical continuous high-temperature carbonization furnace equipment can be optimized through accurate calculation and real-time adjustment of temperature control, reducing heat loss, improving heat conduction efficiency, reducing energy consumption, ensuring stable product quality, shortening production cycle, and improving equipment life, further improving the intelligence and automation level of the production process.
[0053] The working process of the present invention is as follows: when the present invention is in use, the feeding partition 4, the heating partition 3 and the cooling partition 5 in the furnace of the carbonization furnace body are preheated and heated respectively. Preheating can improve working efficiency, and material particles are added to the graphite crucible 8 of the feeding partition 4 of the carbonization furnace body.
[0054] At the same time, the motor 12 drives the first pulley 13 to rotate, the first pulley 13 drives the second pulley 15 to rotate, the second pulley 15 drives the reducer 14 to work, and the output end of the reducer 14 drives the rotating column 22 to rotate, the rotating column 22 drives the first gear 10 to rotate, the first gear 10 drives the second gear 9 to rotate, and the second gear 9 drives the rotary table 18 to rotate. Since the graphite crucible 8 is limited on the rotary table 18, the limiting end plate 21 at the lower end of the graphite crucible 8 can be placed in the receiving groove on the rotary table 18. Therefore, the rotary table 18 is used to drive the graphite crucible 8 to rotate, and the limiting end plate 21 at the lower end of the upper graphite crucible 8 can be sealed and inserted into the limiting groove 20 of the next graphite crucible 8 to achieve the superposition of the graphite crucible 8, and due to the setting of the limiting end plate 21 and the limiting groove 20, the graphite crucible 8 set on the rotary table 18 can synchronously drive the stacked graphite crucible 8 at the upper end to rotate.
[0055] The polygonal graphite shaft 16 is fixed to the inner wall of the frame steel platform 1 by using a fixing rod 19. Since the polygonal graphite shaft 16 fixes the graphite climbing claw body 17 in the graphite crucible 8, the material flow inside the graphite crucible 8 performs a lateral rotation when the graphite crucible 8 rotates, guiding the continuously added material flow, so that the material flow performs a circular motion in the horizontal plane of the superimposed graphite crucibles 8. The waist-shaped leakage holes 26 are set at 120° on the graphite climbing claw body 17, and the leakage holes 24 on the graphite crucible 8 are staggered by 120° between layers to ensure that the material particles fall into the graphite crucible 8 through the waist-shaped leakage holes 26 during the process of falling from the leakage hole 24 to the next graphite crucible 8. During the rotation of the graphite crucible 8, the climbing claw 23 is used to rotate the material flow in the graphite crucible 8 to the specified circumferential angle position. The leakage hole 24 in the graphite crucible 8 flows into the lower layer, and the movement of the material flow realizes the collision, friction and extrusion between the material particles, and the material is heated evenly. The material is heated in the graphite crucible 8 superimposed by the pre-carbonization of the feeding section 4 and simultaneously rotates sideways layer by layer. The material is heated in the graphite crucible 8 superimposed by the high-temperature carbonization of the heating section 3 and simultaneously rotates sideways layer by layer. The material moves to the graphite crucible 8 superimposed by the cooling section 5 and is cooled while rotating sideways layer by layer, and finally rolls into the discharge barrel 11. The discharge of the material is controlled by alternating opening and closing of the superimposed pneumatic hemispherical valves. Waste gas will be generated in the process of carbonization, and the waste gas can be discharged upward through the leakage hole 24. Since the leakage holes 24 in different graphite crucibles 8 are staggered by 120° between layers, the waste gas can be spirally climbed to the exhaust port 7 on the top of the furnace and is not easy to escape with the material upward.
