Description

Technical Field

[0001] This invention belongs to the technical field of high-temperature furnace equipment, and particularly relates to a multi-chamber high-temperature furnace device with step-by-step transmission and its operation method. Background Technology

[0002] In industrial production, many processes require high-temperature conditions, and many reactions need to be carried out continuously within different high-temperature ranges. However, common high-temperature furnaces typically have only one chamber, and the required high-temperature environment for the reaction is provided by heating the entire furnace body. Therefore, they cannot meet the requirement of continuous reaction within different temperature chambers, i.e., they cannot achieve multi-chamber temperature control. Currently, multi-chamber temperature control can be achieved by connecting several vacuum furnaces in series, but the furnace bodies are separate. Because the reaction intermediates cannot be directly removed at high temperatures, the reaction time is affected. Furthermore, the reactants need to be transferred from one furnace body to another, which is cumbersome and cannot meet the requirements of continuous production. In addition, tube furnaces can achieve multi-chamber temperature control, but they can only be operated individually. The reaction can only proceed after the reactants have been transferred from one ambient temperature to another, which cannot achieve continuous reaction. They can only be used as experimental equipment and cannot meet the requirements of mass automated production.

[0003] Simultaneously, a conveyor structure is typically required to transport materials / reaction raw materials requiring heating into the furnace, and then output them from the other end after heating. Since conveyor structures are not limited by temperature, material, or sealing methods, they often employ motor-driven methods (belt drive, chain drive) to complete the transfer. However, these conveyor structures are not suitable as conveying devices for high-temperature, enclosed environments. This is because belt drives and chain drives cannot be sealed, and drive components such as motors and hydraulic rods cannot be used in high-temperature environments. Therefore, optimizing the structure of the high-temperature furnace to minimize heat loss during the conveying process while simultaneously meeting multi-chamber temperature control requirements is crucial.

[0004] CN112674369A discloses a multi-layer high-temperature furnace for drying nuts. The furnace includes a box body with vertically connected cavities at both ends. Several horizontal partitions are arranged between the two vertically connected cavities to form horizontal partitions within the box body. Each horizontal partition contains a mesh conveyor belt, with both ends of each conveyor belt located within a vertically connected cavity. Adjacent conveyor belts are staggered. Several vertical partitions are spaced above each conveyor belt, forming several independent compartments within the box body. Each independent compartment is equipped with a heating assembly. This multi-layer high-temperature furnace utilizes partitions to create multiple independent compartments within the furnace, achieving temperature control across multiple chambers. However, it does not consider the impact of material conveying processes on the furnace temperature.

[0005] CN107860220A discloses a high-efficiency, energy-saving, automated tunnel kiln, which includes a kiln body, kiln cars, a kiln car pushing device, a heating system, a combustion-supporting flue gas system, and a distributed control system. The kiln body is provided with a preheating zone, an oxidation zone, a high-temperature firing zone, and a cooling zone. The heating system includes gas pipelines, oxygen pipelines, and microwave thermal radiation spray guns located on both sides of the kiln body. The distributed control system automatically controls each control unit of the kiln car pushing device, the heating system, and the combustion-supporting flue gas system. Although the kiln body of this tunnel kiln is divided into different reaction sections, there are no corresponding isolation measures between the reaction sections, making effective temperature control impossible; furthermore, the impact of the material conveying process on the furnace temperature is not considered.

[0006] Therefore, there is an urgent need to design a high-temperature furnace with multiple chambers, combining the furnace body structure and material conveying device structure, so that it can simultaneously achieve multi-chamber temperature control and minimize the temperature loss in the high-temperature zone inside the furnace. Summary of the Invention

[0007] To address the shortcomings of existing technologies, the present invention aims to provide a multi-chamber high-temperature furnace device with step-by-step material transfer and its operation method. By simultaneously optimizing the high-temperature furnace structure and material transfer method, the temperature of each chamber can be individually controlled, and the temperature loss in the high-temperature zone of the furnace can be minimized, reducing losses. At the same time, through the coordination of the high-temperature furnace structure and material transfer method, the reaction raw materials can undergo step-by-step continuous reaction in different chambers of the high-temperature furnace, and the multi-chamber high-temperature furnace device with step-by-step material transfer provided by the present invention can realize continuous production.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] In a first aspect, the present invention provides a multi-chamber high-temperature furnace device with step-by-step transmission. The multi-chamber high-temperature furnace device with step-by-step transmission includes a base. The top surface of the base is provided with a tray circulation pushing channel around its perimeter. Along the pushing direction of the tray, the top surface of the base is sequentially provided with a first tray pushing mechanism, a fixed plate pushing mechanism, a high-temperature furnace, a material picking mechanism, a first tray ejection mechanism, a second tray pushing mechanism, and a second tray ejection mechanism. The tray is pushed step-by-step through the first tray pushing mechanism, the first tray ejection mechanism, the second tray pushing mechanism, and the second tray ejection mechanism.

[0010] The first pallet pushing mechanism, the high-temperature furnace, and the material handling mechanism are arranged in a straight line. The pallet circulating pushing channel passes through the high-temperature furnace and the material handling mechanism in sequence. The high-temperature furnace includes a furnace body, and at least three chambers are connected in series in the direction of pallet pushing within the furnace body. Partition doors are provided at the inlet end, outlet end, and between adjacent chambers of the high-temperature furnace. Through the cooperation of the first pallet pushing mechanism and the fixed plate pushing mechanism, the fixed plate containing the reaction raw materials is pushed into the high-temperature furnace. Subsequently, through the step-by-step circulating pushing of the pallet and the opening and closing of the partition doors, the reaction raw materials pass through different chambers in the high-temperature furnace in sequence for a step-by-step continuous reaction.

[0011] This invention employs a pallet-pushing system comprised of a first pallet pushing mechanism, a first pallet pushing mechanism, a second pallet pushing mechanism, and a second pallet pushing mechanism to cyclically push the pallets step by step. Pushing and pushing mechanisms are simultaneously arranged along the same straight line of the pallet circulation pushing channel, enabling various pallet pushing combinations to meet diverse transmission needs. Furthermore, the high-temperature furnace contains multiple serial chambers, with partitions between adjacent chambers to prevent temperature interference between different chambers. This allows for individual and effective temperature control of each chamber, and the partition design effectively reduces temperature loss in the high-temperature zone within the furnace, minimizing energy consumption. Moreover, the pallet circulation pushing channel passes through the interior of the high-temperature furnace, enabling pallet pushing within the furnace itself.

[0012] Meanwhile, the pallet-based sequential circulation system, in conjunction with the opening and closing of each partition door, sequentially pushes the reaction materials into different chambers within the high-temperature furnace for corresponding reactions. This satisfies the requirement for continuous reaction within different high-temperature ranges, thus achieving sequential reactions of the reaction materials under different temperature conditions. Furthermore, the pallet-based sequential circulation system, in conjunction with the fixed plate pushing mechanism, enables continuous transfer of the reaction materials, allowing different reaction stages to occur simultaneously in different chambers of the high-temperature furnace, meeting the requirements of continuous production.

[0013] Furthermore, the distance of a single pallet push is equal to the length of the pallet, while the time interval between two adjacent pallet pushes can be the same or different, determined by the reaction time of the reactants in different chambers. In this invention, the pushing action of the pallet-pushing system and the time interval between two adjacent pallet pushes are controlled by a control unit.

[0014] The multi-chamber high-temperature furnace device with step-by-step transfer provided by this invention optimizes both the furnace structure and the material transfer method, enabling individual temperature control of each chamber and minimizing temperature loss in the high-temperature zone, thus reducing waste. Furthermore, through the coordination of the furnace structure and the material transfer method, the reactants can undergo a continuous, step-by-step reaction in different chambers of the furnace, enabling continuous production.

[0015] As a preferred embodiment of the present invention, the tray circulation pushing channel is formed by the trays arranged in sequence.

[0016] Preferably, the tray circulation pushing channel has a rectangular frame structure.

[0017] Preferably, the first pallet pushing mechanism and the second pallet pushing mechanism are both located on the outer edge of the pallet circulating pushing channel and are arranged diagonally.

[0018] Preferably, the first tray ejection mechanism and the second tray ejection mechanism are both located on the outer edge of the tray circulation pushing channel and are arranged diagonally.

[0019] In this invention, the pallet circulation pushing channel has a rectangular frame structure, and along the pushing direction of the pallets, a first pallet pushing mechanism, a first pallet ejection mechanism, a second pallet pushing mechanism, and a second pallet ejection mechanism are sequentially arranged at the four corners of the pallet circulation pushing channel. Adjacent pallets between the first pallet pushing mechanism and the first pallet ejection mechanism, and between the second pallet pushing mechanism and the second pallet ejection mechanism, are joined by their long sides; while adjacent pallets between the first pallet ejection mechanism and the second pallet pushing mechanism, and between the second pallet ejection mechanism and the first pallet pushing mechanism, are joined by their short sides, thereby realizing the step-by-step circulation pushing of the pallets within the pallet circulation pushing channel.

[0020] As a preferred embodiment of the present invention, limiting members are provided on both sides of the tray circulation pushing channel, and the limiting members are used to maintain the straight pushing of the tray.

[0021] It should be noted that the present invention does not impose specific requirements or special limitations on the shape, size and material of the limiting component. Any limiting component that can limit the pallet and keep the pallet pushed in a straight line is applicable to the present invention. Those skilled in the art can make adjustments to the applicability according to the actual process conditions and needs.

[0022] In this invention, no limiting components are provided at the tray circulation pushing channel directly opposite the first tray pushing mechanism, the first tray pushing mechanism, the second tray pushing mechanism, and the second tray pushing mechanism. This means that all three mechanisms can directly contact the trays within the circulation pushing channel. The first tray pushing mechanism, the first tray pushing mechanism, the second tray pushing mechanism, and the second tray pushing mechanism simultaneously push or push the trays, thereby achieving a progressively cyclical pushing of the trays.

[0023] Preferably, the first pallet pushing mechanism, the first pallet pushing mechanism, the second pallet pushing mechanism, and the second pallet pushing mechanism work together to push the pallet a distance equal to the length of the pallet in a single operation.

[0024] As a preferred technical solution of the present invention, the fixed plate pushing mechanism is located on the inner edge of the tray circulation pushing channel between the first tray pushing mechanism and the high-temperature furnace, and is slidably connected to the base. After the fixed plate containing the reaction raw materials is placed on the tray and pushed once with the tray, the fixed plate pushing mechanism pushes the fixed plate containing the reaction raw materials into the high-temperature furnace.

[0025] In this invention, after the fixed plate containing the reactants is pushed once along with the pallet, the fixed plate pushing mechanism slides towards the high-temperature furnace, pushing the fixed plate containing the reactants into the chamber at the inlet end of the high-temperature furnace. Then, the fixed plate pushing mechanism slides back to its original position. It should be noted that the fixed plate pushing mechanism only pushes the fixed plate on the surface of the pallet and does not push the pallet itself.

[0026] As a preferred embodiment of the present invention, the distance between adjacent partition doors in the high-temperature furnace is equal.

[0027] Preferably, the distance between adjacent partitions is equal to the length of the tray.

[0028] This invention sets the distance between adjacent partitions to be equal to the length of the pallet, meaning that the length of each chamber in the pallet pushing direction is equal to the length of the pallet. This is because the distance pushed in a single push during the step-by-step cycle of the pallet is equal to the length of the pallet. Therefore, each time a pair of pallets is used for one push, the reactants in one chamber can be accurately delivered to the next adjacent chamber to continue the reaction. This achieves step-by-step reaction of the reactants under different temperature conditions and also allows different reaction stages to be carried out simultaneously in different chambers of the high-temperature furnace, meeting the requirements of continuous production.

[0029] Preferably, the chamber near the inlet end of the high-temperature furnace is a first transition chamber, and the chamber near the outlet end of the high-temperature furnace is a second transition chamber. At least one reaction chamber is connected in series between the first transition chamber and the second transition chamber.

[0030] This invention sets the inlet and outlet chambers of a high-temperature furnace as a first transition chamber and a second transition chamber with lower temperatures, respectively. That is, both the inlet and outlet of the high-temperature furnace are low-temperature zones, while the reaction chamber in the middle of the furnace is a high-temperature reaction zone. The first transition chamber preheats the reaction materials, achieving a gradual temperature increase, while the second transition chamber gradually cools the reaction materials. In other words, the entire process of gradual heating, high-temperature reaction, and gradual cooling is completed through different chambers within the high-temperature furnace. Furthermore, due to the partition doors, the temperatures of each chamber do not interfere with each other. Compared to current single-chamber furnaces that raise the temperature from the initial temperature to the reaction temperature and then lower it to the usable temperature, this invention allows the high-temperature zone to continuously maintain its operating temperature, significantly reducing heating time and improving reaction efficiency.

[0031] Meanwhile, the high-temperature reaction chamber is located in the middle of the high-temperature furnace, and the low-temperature transition zones and partition doors on both sides protect the high-temperature reaction chamber, preventing it from directly contacting the external environment and thus avoiding temperature loss. Although the first and second transition chambers will come into contact with the outside world during the feeding and discharging process of the high-temperature furnace, their temperature is not high, and even if they come into contact with the outside world, the energy loss is small.

[0032] Preferably, at least one of the reaction chambers in the high-temperature furnace has a feeding port at its top.

[0033] In this invention, a feeding port is provided at the top of the reaction chamber. When some raw materials need to be added during the reaction, they can be added through the feeding port.

[0034] Preferably, a gap is left between the bottom of the partition door and the support plate.

[0035] In this invention, there is a certain gap between the partition door and the pallet, which ensures that the pallet can still move forward even when the partition door is closed. This satisfies the requirement that the internal reaction materials can be transferred even when the partition doors at the inlet and outlet ends of the high-temperature furnace are closed, ensuring that the high-temperature reaction zone does not come into contact with the external environment and further reducing its temperature loss.

[0036] As a preferred technical solution of the present invention, the base is further externally connected to a material receiving platform, which is fixedly disposed between the first pallet pushing mechanism and the high-temperature furnace, and close to the first pallet pushing mechanism.

[0037] In this invention, a fixed plate containing the reactive raw materials is placed on the receiving platform, and then the fixed plate containing the reactive raw materials is placed on the surface of the pallet by an external transfer mechanism, such as a gripper.

[0038] Preferably, a feeding platform is externally connected to the base, and the feeding platform is located near the outlet end of the high-temperature furnace. The material handling mechanism grabs the fixed plate containing the reaction product and places it on the feeding platform.

[0039] Preferably, a pallet fixing mechanism is also provided on the top surface of the base. The pallet fixing mechanism is located on the side of the material taking mechanism away from the high-temperature furnace and is arranged in a straight line with the first pallet pushing mechanism, the high-temperature furnace and the material taking mechanism.

[0040] Preferably, the tray fixing mechanism is located at the outer edge of the tray circulation pushing channel.

[0041] In this invention, no limiting component is provided at the pallet circulation pushing channel directly opposite the pallet fixing mechanism, meaning that the pallet fixing mechanism can directly contact the pallet in the pallet circulation pushing channel.

[0042] In this invention, the purpose of setting up a tray fixing mechanism is to limit the relative movement of the tray when the fixing plate pushing mechanism pushes the fixing plate containing the reaction raw materials into the chamber at the inlet end of the high-temperature furnace.

[0043] As a preferred embodiment of the present invention, the reaction raw materials are placed in a reactor dish, and the surface of the fixing plate is provided with a groove that matches the reactor dish, so that the reactor dish is inserted into the groove for fixation.

[0044] Preferably, the surface of the tray has a through groove at both ends, thereby forming a U-shaped structure, and the fixing plate is slidably installed in the groove of the tray.

[0045] In this invention, the groove on the fixing plate can ensure the accuracy of the placement of the reactor vessel. The fixing plate is slidably installed in the groove of the support plate, so that the fixing plate and the support plate can be relatively displaced by external force. That is, the groove of the support plate limits the fixing plate and ensures that the fixing plate moves along the groove.

[0046] In a second aspect, the present invention provides an operating method for the multi-chamber high-temperature furnace apparatus with step-by-step transmission as described in the first aspect, the operating method comprising:

[0047] Through the cooperation of the first pallet pushing mechanism and the fixed plate pushing mechanism, the fixed plate containing the reaction raw materials is pushed into the high-temperature furnace. Then, through the step-by-step circulation of the pallet and the opening and closing of the partition doors of each chamber in the high-temperature furnace, the reaction raw materials pass through different chambers in the high-temperature furnace in sequence to carry out a step-by-step continuous reaction.

[0048] As a preferred technical solution of the present invention, the operating method specifically includes:

[0049] S1: After the fixed plate containing the reaction raw materials is placed on the pallet, the partition door between the adjacent reaction chambers in the high-temperature furnace is opened, and then the fixed plate containing the reaction raw materials is pushed once along with the pallet.

[0050] S2: The partition door between adjacent reaction chambers in the high-temperature furnace is closed, the partition door at the inlet end of the high-temperature furnace is opened, and the fixed plate pushing mechanism pushes the fixed plate containing the reaction raw materials into the first transition chamber of the high-temperature furnace.

[0051] S3: The partition door at the inlet end of the high-temperature furnace is closed, the partition door at the outlet end of the high-temperature furnace is opened, the material handling mechanism grabs the fixed plate containing the reaction product in the second transition chamber onto the feeding platform, and then the partition door at the outlet end of the high-temperature furnace is closed.

[0052] S4: Repeat steps S1-S3, and through the step-by-step cyclical pushing of the tray and the opening and closing of the partition door, the reaction raw materials sequentially pass through different chambers in the high-temperature furnace for a step-by-step continuous reaction.

[0053] In a preferred embodiment of the present invention, the distance of a single push of the tray in the step-by-step cyclic push is equal to the length of the tray.

[0054] Preferably, the distance between adjacent partition doors in the high-temperature furnace is equal to the length of the pallet.

[0055] Preferably, the reaction raw materials are placed in a reactor dish, the reactor dish is fixed to the fixing plate, and the fixing plate is slidably mounted on the support plate.

[0056] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0057] The multi-chamber high-temperature furnace device with step-by-step transfer provided by this invention optimizes both the furnace structure and the material transfer method, enabling individual temperature control of each chamber and minimizing temperature loss in the high-temperature zone, thus reducing waste. Furthermore, through the coordination of the furnace structure and the material transfer method, the reactants can undergo a continuous, step-by-step reaction in different chambers of the furnace, enabling continuous production.

[0075] It should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0076] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0077] In one specific embodiment, the present invention provides a multi-chamber high-temperature furnace device with step-by-step transmission, such as... Figure 1 , Figure 2 and Figure 3 As shown, the multi-chamber high-temperature furnace device with step-by-step transmission includes a base 1. The top surface of the base 1 is provided with a pallet circulation pushing channel 20. Along the pushing direction of the pallet 2, the top surface of the base 1 is sequentially provided with a first pallet pushing mechanism 3, a fixed plate pushing mechanism 4, a high-temperature furnace, a material picking mechanism 6, a first pallet ejection mechanism 7, a second pallet pushing mechanism 8, and a second pallet ejection mechanism 9. The pallet 2 is pushed step-by-step through the first pallet pushing mechanism 3, the first pallet ejection mechanism 7, the second pallet pushing mechanism 8, and the second pallet ejection mechanism 9.

[0078] The first pallet pushing mechanism 3, the high-temperature furnace, and the material handling mechanism 6 are arranged in a straight line. The pallet circulating pushing channel 20 passes through the high-temperature furnace and the material handling mechanism 6 in sequence. The high-temperature furnace includes a furnace body 5. At least three chambers are connected in series in the pushing direction of the pallet 2 within the furnace body 5. Partition doors are provided at the inlet end, outlet end, and between adjacent chambers of the high-temperature furnace. Through the cooperation of the first pallet pushing mechanism 3 and the fixed plate pushing mechanism 4, the fixed plate 17 containing the reaction raw materials is pushed into the high-temperature furnace. Subsequently, through the step-by-step circulating pushing of the pallet 2 and the opening and closing of the partition doors, the reaction raw materials pass through different chambers in the high-temperature furnace in sequence for a step-by-step continuous reaction.

[0079] In this invention, a pallet-pushing system consisting of a first pallet pushing mechanism 3, a first pallet pushing mechanism 7, a second pallet pushing mechanism 8, and a second pallet pushing mechanism 9 is used to cyclically push the pallet 2 step by step. Pushing and pushing mechanisms are simultaneously arranged in the same straight line direction of the pallet circulation pushing channel 20, enabling various pallet 2 pushing combinations to meet diverse transmission needs. Furthermore, the high-temperature furnace contains multiple series chambers, with partitions between adjacent chambers to prevent temperature interference between different chambers. This allows for individual and effective temperature control of each chamber, and the partition design effectively reduces temperature loss in the high-temperature zone of the furnace, minimizing energy consumption. In addition, the pallet circulation pushing channel 20 passes through the interior of the high-temperature furnace, enabling the pushing of the pallet 2 within the furnace.

[0080] Meanwhile, the pallet-level circulation system, in conjunction with the opening and closing of each partition door, sequentially pushes the reaction materials into different chambers within the high-temperature furnace for corresponding reactions. This satisfies the requirement that the reaction needs to be carried out continuously in different high-temperature ranges, thus realizing the step-by-step reaction of the reaction materials under different temperature conditions. Furthermore, the pallet-level circulation system, in conjunction with the fixed plate pushing mechanism 4, enables the continuous transfer of reaction materials, allowing different reaction stages to be carried out simultaneously in different chambers of the high-temperature furnace, meeting the requirements of continuous production.

[0081] Furthermore, the distance of a single pallet push is equal to the length of pallet 2, while the time interval between two adjacent pallet pushes can be the same or different, determined based on the reaction time of the reactants in different chambers. In this invention, the pushing action of the pallet-pushing system and the time interval between two adjacent pallet pushes are controlled by a control unit.

[0082] The multi-chamber high-temperature furnace device with step-by-step transfer provided by this invention optimizes both the furnace structure and the material transfer method, enabling individual temperature control of each chamber and minimizing temperature loss in the high-temperature zone, thus reducing waste. Furthermore, through the coordination of the furnace structure and the material transfer method, the reactants can undergo a continuous, step-by-step reaction in different chambers of the furnace, enabling continuous production.

[0083] Furthermore, such as Figure 4 and Figure 5 As shown, the pallet circulation pushing channel 20 is formed by the pallets 2 arranged in sequence; the pallet circulation pushing channel 20 has a rectangular frame structure.

[0084] Furthermore, the first pallet pushing mechanism 3 and the second pallet pushing mechanism 8 are both located on the outer edge of the pallet circulation pushing channel 20 and are arranged diagonally; the first pallet ejection mechanism 7 and the second pallet ejection mechanism 9 are both located on the outer edge of the pallet circulation pushing channel 20 and are arranged diagonally.

[0085] In this invention, the pallet circulation pushing channel 20 has a rectangular frame structure, and along the pushing direction of the pallet 2, a first pallet pushing mechanism 3, a first pallet ejection mechanism 7, a second pallet pushing mechanism 8, and a second pallet ejection mechanism 9 are sequentially arranged at the four corners of the pallet circulation pushing channel 20. Adjacent pallets 2 between the first pallet pushing mechanism 3 and the first pallet ejection mechanism 7, and between the second pallet pushing mechanism 8 and the second pallet ejection mechanism 9, are connected by their long sides; while adjacent pallets 2 between the first pallet ejection mechanism 7 and the second pallet pushing mechanism 8, and between the second pallet ejection mechanism 9 and the first pallet pushing mechanism 3, are connected by their short sides, thereby realizing the step-by-step circulation pushing of the pallet 2 within the pallet circulation pushing channel 20. As shown... Figure 3 As shown, the path of the pallet being pushed in a step-by-step cycle consists of a linear motion path and a cyclical motion path.

[0086] Furthermore, limiting members are provided on both sides of the tray circulation pushing channel 20, and the limiting members are used to maintain the straight pushing of the tray.

[0087] It should be noted that the present invention does not impose specific requirements or special limitations on the shape, size and material of the limiting component. Any limiting component that can limit the pallet 2 and keep the pallet 2 pushed in a straight line is applicable to the present invention. Those skilled in the art can make adjustments to the applicability according to the actual process conditions and needs.

[0088] In this invention, no limiting components are provided at the pallet circulation pushing channel 20 directly opposite the first pallet pushing mechanism 3, the first pallet pushing mechanism 7, the second pallet pushing mechanism 8, and the second pallet pushing mechanism 9. This means that all three mechanisms can directly contact the pallet 2 within the pallet circulation pushing channel 20. The first pallet pushing mechanism 3, the first pallet pushing mechanism 7, the second pallet pushing mechanism 8, and the second pallet pushing mechanism 9 simultaneously push or push the pallet 2, thereby achieving the step-by-step circulation pushing of the pallet 2.

[0089] Furthermore, the first pallet pushing mechanism 3, the first pallet ejection mechanism 7, the second pallet pushing mechanism 8, and the second pallet ejection mechanism 9 cooperate to push the pallet 2 a distance equal to the length of the pallet 2 in a single operation.

[0090] Furthermore, the fixed plate pushing mechanism 4 is located on the inner edge of the tray circulation pushing channel 20 between the first tray pushing mechanism 3 and the high-temperature furnace, and is slidably connected to the base 1. After the fixed plate 17 containing the reaction raw materials is placed on the tray 2 and pushed once with the tray 2, the fixed plate pushing mechanism 4 pushes the fixed plate 17 containing the reaction raw materials into the high-temperature furnace.

[0091] In this invention, after the fixed plate 17 containing the reactants is pushed once along with the pallet 2, the fixed plate pushing mechanism 4 slides towards the high-temperature furnace, pushing the fixed plate 17 containing the reactants into the chamber at the inlet end of the high-temperature furnace. Then, the fixed plate pushing mechanism slides back to its original position. It should be noted that the fixed plate pushing mechanism only pushes the fixed plate 17 on the surface of the pallet 2 and does not push the pallet 2 itself.

[0092] Furthermore, the distance between adjacent partition doors in the high-temperature furnace is equal; even further, the distance between adjacent partition doors is equal to the length of the pallet 2.

[0093] This invention sets the distance between adjacent partitions to be equal to the length of the pallet 2, meaning that the length of each chamber in the pushing direction of the pallet 2 is equal to the length of the pallet 2. This is because the distance pushed in a single push during the step-by-step cyclic pushing process of the pallet 2 is equal to the length of the pallet 2. Therefore, each time the pallet 2 is used for one push, the reactants in one chamber can be accurately sent to the next adjacent chamber to continue the reaction. This realizes the step-by-step reaction of the reactants under different temperature conditions, and also allows different reaction stages to be carried out simultaneously in different chambers of the high-temperature furnace, meeting the requirements of continuous production.

[0094] Furthermore, the chamber near the inlet end of the high-temperature furnace is the first transition chamber 21, and the chamber near the outlet end of the high-temperature furnace is the second transition chamber 23. At least one reaction chamber 22 is connected in series between the first transition chamber 21 and the second transition chamber 23.

[0095] This invention sets the inlet and outlet chambers of the high-temperature furnace as a first transition chamber 21 and a second transition chamber 23 with lower temperatures, respectively. That is, both the inlet and outlet of the high-temperature furnace are low-temperature zones, while the reaction chamber 22 in the middle of the high-temperature furnace is a high-temperature reaction zone. The first transition chamber 21 can preheat the reaction raw materials to achieve a gradual temperature increase, while the second transition chamber 23 can achieve a gradual temperature decrease. In other words, the entire process of gradual temperature increase, high-temperature reaction, and gradual temperature decrease is completed through different chambers within the high-temperature furnace. Furthermore, due to the partition doors, the temperatures of each chamber do not interfere with each other. Compared to the current single-chamber furnace, which raises the temperature from the initial temperature to the reaction temperature and then lowers it to the usable temperature, the high-temperature zone of this invention can continuously maintain the operating temperature, greatly reducing the heating time and improving the reaction efficiency.

[0096] Meanwhile, the high-temperature reaction chamber 22 is located in the middle of the high-temperature furnace. The low-temperature transition zones and partition doors on both sides protect the high-temperature reaction chamber 22, preventing it from directly contacting the external environment and thus avoiding temperature loss. Although the first transition chamber 21 and the second transition chamber 23 will come into contact with the outside world during the feeding and discharging process of the high-temperature furnace, their temperature is not high, and even if they come into contact with the outside world, the energy loss is small.

[0097] Furthermore, at least one of the reaction chambers 22 in the high-temperature furnace is provided with a feeding port 19 at its top. In this invention, the top of the reaction chamber 22 is provided with a feeding port 19, which can be used to add raw materials when some raw materials need to be added during the reaction.

[0098] Furthermore, a gap is left between the bottom of the partition door and the support plate 2. In this invention, there is a certain fitting gap between the partition door and the support plate 2, which ensures that the support plate 2 can still move forward even when the partition door is closed. This satisfies the requirement that the internal reaction materials can be transferred even when the partition doors at the inlet and outlet ends of the high-temperature furnace are closed, ensuring that the high-temperature reaction zone does not come into contact with the external environment and further reducing its temperature loss.

[0099] Furthermore, a material receiving platform 14 is externally connected to the base 1. The material receiving platform 14 is fixedly disposed between the first pallet pushing mechanism 3 and the high-temperature furnace, and is close to the first pallet pushing mechanism 3.

[0100] In this invention, a fixed plate 17 containing reactive raw materials is placed on a material receiving platform 14, and then an external transfer mechanism, such as a gripper, is used to place the fixed plate 17 containing reactive raw materials onto the surface of a pallet 2.

[0101] Furthermore, a feeding platform 15 is externally connected to the base 1. The feeding platform 15 is located near the outlet end of the high-temperature furnace. The material handling mechanism 6 grabs the fixed plate 17 containing the reaction product and places it on the feeding platform 15.

[0102] Furthermore, a pallet fixing mechanism 16 is also provided on the top surface of the base 1. The pallet fixing mechanism 16 is located on the side of the material taking mechanism 6 away from the high-temperature furnace, and is arranged in a straight line with the first pallet pushing mechanism 3, the high-temperature furnace and the material taking mechanism 6. The pallet fixing mechanism 16 is located on the outer edge of the pallet circulating pushing channel 20.

[0103] In this invention, no limiting component is provided at the pallet circulation pushing channel 20 directly opposite the pallet fixing mechanism 16, meaning that the pallet fixing mechanism 16 can directly contact the pallet 2 in the pallet circulation pushing channel 20. Meanwhile, the purpose of providing the pallet fixing mechanism 16 in this invention is to limit the relative movement of the pallet 2 when the fixing plate pushing mechanism 4 pushes the fixing plate 17 containing the reaction raw materials into the chamber at the inlet end of the high-temperature furnace, as the pallet 2 may move relative to the fixing plate 17.

[0104] Furthermore, such as Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the reaction raw materials are placed in the reactor dish 18. The surface of the fixing plate 17 is provided with a groove that matches the reactor dish 18, and the reactor dish 18 is inserted into the groove for fixation. The surface of the support plate 2 is provided with a groove that passes through both ends, so that the support plate 2 forms a U-shaped structure. The fixing plate 17 is slidably installed in the groove of the support plate 2.

[0105] In this invention, the groove on the fixing plate 17 can ensure the accuracy of the placement of the reactor vessel 18. The fixing plate 17 is slidably installed in the groove of the support plate 2, and the fixing plate 17 moves together with the support plate 2. At the same time, the fixing plate 17 and the support plate 2 can be relatively displaced by external force. That is, the groove on the support plate 2 limits the fixing plate 17 and ensures that the fixing plate 17 moves along the groove.

[0106] Exemplarily, based on this specific embodiment, the present invention provides a multi-chamber high-temperature furnace device with step-by-step transmission, such as... Figure 1 and Figure 2As shown, a reaction chamber 22 is connected in series between the first transition chamber 21 and the second transition chamber 23. The partition door at the inlet end of the high-temperature furnace is an inlet partition door 10. The partition door between the first transition chamber 21 and the reaction chamber 22 is a first partition door 11. The partition door between the reaction chamber 22 and the second transition chamber 23 is a second partition door 12. The partition door at the outlet end of the high-temperature furnace is an outlet partition door 13.

[0107] Accordingly, the present invention provides, exemplarily, an operating method for the above-described multi-chamber high-temperature furnace apparatus with step-by-step transmission, such as... Figure 11 As shown, the operating method includes:

[0108] S1: As Figure 12 As shown, this step includes the following four processes:

[0109] (1) Place the fixing plate 17 with the reactor vessel 18 fixed on the surface of the tray 2, i.e., position 1;

[0110] (2) Both the first partition door 11 and the second partition door 12 in the high-temperature furnace are opened;

[0111] (3) Subsequently, the fixing plate 17, which is fixed to the reactor vessel 18, is pushed once along with the tray 2 to reach position 2;

[0112] (4) Then place the next fixing plate 17 with the reactor vessel 18 fixed on the surface of the tray 2, i.e., position 1;

[0113] S2: Both the first partition door 11 and the second partition door 12 in the high-temperature furnace are closed;

[0114] S3: The inlet partition door 10 of the high-temperature furnace is opened, and the fixed plate pushing mechanism 4 pushes the fixed plate 17, which is fixed with the reactor vessel 18, into the first transition chamber 21 of the high-temperature furnace.

[0115] S4: The inlet partition door 10 of the high-temperature furnace is closed;

[0116] S5: The outlet partition door 13 opens, and the material handling mechanism 6 grabs out the fixing plate 17 that is fixed to the reactor dish 18 in the second transition chamber 23;

[0117] S6: Subsequently, the outlet partition door 13 of the high-temperature furnace is closed;

[0118] S7: The material handling mechanism 6 places the fixing plate 17, on which the reactor vessel 18 is fixed, on the feeding platform 15 to complete one round of feeding and discharging cycle;

[0119] like Figure 13 and Figure 14As shown, repeating steps S1-S7, the continuous feeding and discharging process of the high-temperature furnace is achieved by the step-by-step cyclic pushing of the pallet 2 in conjunction with the opening and closing of the high-temperature furnace partition door; wherein the reaction raw materials pass through the first transition chamber 21, the reaction chamber 22 and the second transition chamber 23 in the high-temperature furnace in sequence to undergo a process of gradual heating, high-temperature reaction and gradual cooling.

[0120] Before proceeding to step S1, the temperatures of the first transition chamber 21, the reaction chamber 22, and the second transition chamber 23 in the high-temperature furnace are adjusted to the set temperatures, the reaction raw materials are added to the reactor dish 18, and then the reactor dish 18 is fixed in the groove of the fixing plate 17.

[0121] It should be noted that, as Figure 15 As shown, in the first and second rounds of feeding and discharging cycles, due to the step-by-step pushing of the pallet 2, the fixing plate 17 that fixes the reactor vessel 18 has not yet entered the second transition chamber 23 along with the pallet 2, so there is no fixing plate 17 that fixes the reactor vessel 18 in the second transition chamber 23; from the third round of feeding and discharging cycles, there is a fixing plate 17 that fixes the reactor vessel 18 in the second transition chamber 23.

[0122] Furthermore, based on actual production process conditions and requirements, multiple reaction chambers 22 can be connected in series between the first transition chamber 21 and the second transition chamber 23. In this case, the operating method provided in this specific embodiment is the basis, and by analogy, the continuous feeding, step-by-step continuous reaction and continuous discharge process of the high-temperature furnace can be realized to achieve the requirements of continuous production.

[0123] The applicant declares that the above description is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention fall within the protection and disclosure scope of the present invention.
