[0002] The crucible conveyor system is used for conveying high-temperature materials in high-temperature manufacturing processes. With the increasing production capacity of lithium-ion battery cathode materials, the amount of material loaded into crucibles is constantly increasing, and the conveying speed is continuously improving, leading to a further compression of the cooling time during material transport. High-temperature materials need to undergo efficient cooling treatment before being poured into the crucibles to reduce heat damage to subsequent equipment and minimize the risk of material performance degradation. Summary of the Invention

Detailed Implementation

[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0019] The following is for reference. Figures 1-3 A sagger conveying system according to an embodiment of this application is described.

[0020] The sagger conveying system is a conveying device used in high-temperature processes to carry and transport saggers 20, enabling the saggers 20 to flow stably in a preset direction. The high-temperature process can be used for calcining lithium battery cathode materials.

[0021] The sagger 20 is a high-temperature resistant ceramic or refractory container, mainly used to support materials during high-temperature processing, such as sintering or annealing, which can reduce the direct contact of materials with the high-temperature furnace body or external contamination.

[0022] like Figure 1 and Figure 2 As shown, the sagger conveying system provided in this application embodiment includes a track 100 and a cooling component 200.

[0023] The track 100 is the guiding and load-bearing basic structure for conveying the crucible 20. It can provide a path for the movement of the crucible 20, so that the conveying process of the crucible 20 has a certain stability and directionality.

[0024] like Figure 1 As shown, track 100 forms a transport channel 110 extending along the first direction X.

[0025] In other words, the transport channel 110 extends along the first direction X, and the sagger 20 can be transported in the transport channel 110.

[0026] The transport component 800 in track 100 may include roller conveyor components, tracked transport components, chain transport components, belt-type track or guide rail transport components, etc.

[0027] Among them, such as Figure 1 As shown, the roller conveyor system comprises multiple rollers arranged in essentially parallel rows. The rollers are driven to rotate, and friction causes the saggers 20 placed on the rollers to move. The roller conveyor system provides smooth transport and has a strong load-bearing capacity. The roller density is not necessarily proportional to... Figure 1 same, Figure 1 This is only for illustration purposes and does not impose any restrictions on the arrangement density of the rollers. The arrangement density of the rollers needs to ensure that the sagger 20 on them can be transported smoothly.

[0028] The roller can include a roller wheel and a roller body. The roller wheel can be made of a wear-resistant and high-temperature resistant hard material, including but not limited to ceramic materials. Specifically, alumina ceramic or silicon nitride ceramic, which have excellent high-temperature stability and wear resistance, can be selected to meet the long-term contact conveying requirements of the high-temperature crucible 20. The roller body can adopt a composite structure design. Its base material can be a high-strength metal material, including but not limited to stainless steel. The surface of the base material can be coated with a functional coating, including but not limited to nano-ceramic coating or nano-wear-resistant coating. Through the synergistic effect of the coating and the base material, the high-temperature resistance, corrosion resistance and service life of the roller body are improved, and the risk of roller deformation or surface wear under high-temperature conditions is reduced.

[0029] The tracked transport component uses the track as its core transmission component. The transport component can be equipped with a guide and limiting structure that cooperates with the track. The scoop 20 is placed directly on the track. As the track circulates, it drives the scoop 20 to move along the transport component. The tracked transport component has a large contact area, stable load-bearing capacity, and is adaptable to complex transport paths. The components in the tracked transport component can be made of rigid metal structures.

[0030] The chain-type transport component uses a chain as its core transmission component. The transport component has a guide structure that works with the chain. The sagger 20 is fixed to the chain via a connector. When the chain moves, it drives the sagger 20 to move along the transport component. The chain-type transport component is suitable for long-distance transport and can adapt to certain elevation differences. The components in the chain-type transport component can be made of rigid metal structures.

[0031] Belt conveyor components include conveyor belts, idlers, and drive units. The sagger 20 is placed on the conveyor belt, and transport is achieved through the cyclical motion of the conveyor belt. Belt conveyor components offer advantages such as lower noise and more uniform conveying speed. Components in belt conveyor components can be made of high-temperature resistant materials and are not easily damaged by high temperatures due to cooling radiation from cooling components. The drive unit of the belt conveyor component can be externally mounted, thereby reducing the risk of high-temperature damage.

[0032] The guide rail type transport component is equipped with a dedicated guide rail, and the crucible 20 is equipped with a corresponding slider or roller. Driven by a cylinder or motor, the crucible 20 slides along the rail, resulting in high positioning accuracy. The components in the guide rail type transport component can be made of high-temperature resistant materials and are protected from high-temperature damage by the cooling radiation from cooling components. The drive unit of the guide rail type transport component can be externally mounted, thereby reducing the risk of high-temperature damage.

[0033] The transport channel 110 is a spatial area formed by the track 100 for the crucible 20 to pass through, and is the path carrier for the crucible 20 to complete the process flow.

[0034] The first direction X refers to the preset main conveying direction of the sagger 20 in the conveying system, which can be set as a horizontal straight direction, a turning direction or a sloped direction according to the production line layout.

[0035] Cooling component 200 is a functional component with cooling function, used to cool down the sagger 20 and the high-temperature material loaded in the sagger 20.

[0036] like Figure 1 and Figure 2 As shown, the cooling component 200 is located on at least one side of the transport channel 110.

[0037] The cooling component 200 can be located on one side of the transport channel 110; or, the cooling component 200 can be installed on at least two of the two sides, top surface, or bottom surface of the transport channel 110 instead of one side, to help the sagger 20 and the material achieve more uniform cooling and reduce the problem of insufficient local cooling.

[0038] When the transport component 800 is a tracked transport component, the cooling element 200 can be arranged inside the track. The track can be made of rigid metal. By integrating the cooling function with the transport component, the track can directly contact the crucible 20 and conduct heat for cooling. The large contact surface between the track and the bottom of the crucible 20 can significantly increase the heat exchange area; at the same time, the rigid metal track has rapid heat conduction capability, which can accelerate the heat conduction between the crucible 20 and the track; in addition, the cooling element 200 built into the track can keep the track at a low temperature to cool the crucible in real time during transport.

[0039] like Figure 3 As shown, the cooling component 200 has a cooling chamber 210 and a gas passage 220. The cooling chamber 210 is used to communicate with an external cooling system. The gas passage 220 is located inside the cooling chamber 210. The outlet 224 of the gas passage 220 faces the transport passage 110. The inlet 223 of the gas passage 220 is used to connect to the protective gas.

[0040] The cooling chamber 210 is a cavity structure opened inside the cooling component 200, used to circulate cooling medium from the external cooling system, and to cool the surrounding environment of the cooling component 200 through heat exchange.

[0041] The cooling medium can be industrial cooling water, such as ordinary circulating cooling water or deionized cooling water; or, the cooling medium can be heat transfer oil, which has the characteristics of not easily vaporizing at high temperatures, high boiling point, and good thermal stability; or, the cooling medium can be antifreeze cooling medium such as ethylene glycol aqueous solution or propylene glycol aqueous solution. It should be noted that the selection of various cooling media must be matched with the structural design of the external cooling system, and determined comprehensively in combination with the cooling rate requirements under specific operating conditions, material characteristics, and operating costs. As long as the cooling medium meets the heat exchange requirements of the cooling chamber 210 and the system operation stability requirements, it falls within the protection scope of this application.

[0042] The outer wall of the cooling chamber 210 can be constructed using a composite material structure. For example, the main material of the composite structure can be austenitic stainless steel 304 (SUS304), and the surface of the main material can be coated with polytetrafluoroethylene (PTFE). The composite material combination of SUS304 and PTFE coating can be replaced by other equivalent composite materials, including but not limited to combinations of high-speed steel and silicon nitride coatings, as well as tungsten carbide composite layers. The alternative materials must meet the following core performance requirements: the internal main material must have high thermal conductivity, and the coating must have wear resistance, high temperature resistance, and high thermal conductivity. By selecting different composite material combinations, it is possible to adapt to different wear intensities during material transport, improving the adaptability and service life of the outer wall of the water-cooled jacket of the cooling chamber 210 under diverse operating conditions.

[0043] The gas passage 220 is an independently set gas flow pipeline inside the cooling component 200, used to transport protective gas. Its two ends are the air inlet 223 and the air outlet 224, respectively.

[0044] The protective gas can be air; or it can be an inert gas, such as argon (Ar) or helium (He).

[0045] The gas channel 220 is integrated into the cooling chamber 210, which is conducive to the compact design of the cooling component 200. At the same time, the low temperature environment of the cooling chamber 210 can cool the protective gas in the gas channel 220.

[0046] The air inlet 223 can be connected to a protective gas source to provide protective gas, and the air outlet 224 faces the transport channel 110 so that the protective gas can be blown toward the crucible 20. By introducing the protective gas, gases such as CO2 or water vapor that are easy to react with materials can be discharged from the transport channel 110, while taking away the heat of the crucible 20.

[0047] In high-temperature processes, such as the preparation of ternary cathode materials, the material temperature inside the crucible 20 after sintering can reach over 150°C. With increasing production capacity, the amount of material loaded into crucibles is constantly increasing, and the transportation speed is continuously accelerating, further compressing the cooling time of the material during transport. High-temperature materials need to undergo efficient cooling treatment before being transferred to the crucible to reduce heat damage to subsequent equipment and minimize the risk of material performance degradation.

[0048] In related technologies, only a gas channel is set up to cool the sagger and its internal materials using protective gas. However, with the increase in production capacity, the cooling efficiency of the protective gas within the limited track length is low, making it difficult to meet the cooling requirements of the materials. To address this, related technologies have attempted to improve this by increasing the number of protective gas sources. However, this solution not only increases equipment purchase costs but also raises production energy consumption and equipment maintenance costs, and still fails to effectively improve the cooling effect on the materials inside the sagger. Furthermore, using only protective gas for cooling means that in summer, when the ambient temperature is high, the protective gas temperature will rise synchronously with the ambient temperature, further weakening its cooling effect on the materials inside the sagger and resulting in poor production stability. This directly leads to excessively high material discharge temperatures, and the high-temperature material coming into contact with downstream crushing and conveying equipment can easily cause high-temperature failures. It may also accelerate the aging or damage of pipelines and flexible connections, thereby creating a risk of foreign matter contamination. Meanwhile, after sintering, materials are typically transferred using positive pressure conveying equipment. Excessively high material temperatures may cause the adhesive on the ceramic patches inside the pipeline to fail and detach due to prolonged exposure to high temperatures, resulting in a large amount of metallic foreign matter and system damage. This not only affects product safety but may also reduce the capacity and operating efficiency of subsequent equipment.

[0049] In this embodiment, a cooling element 200 is installed in the transport channel 110, and the cooling chamber 210 is connected to an external cooling system to achieve active heat exchange cooling. Protective gas is supplied to the transport channel 110 via the gas channel 220, forming a dual cooling structure. Furthermore, when the cooling element 200 is arranged on multiple sides, compared to a single-sided cooling structure, it can cool the sagger 20 and the high-temperature material inside from multiple directions, such as both sides or the top and bottom sides of the transport channel 110, effectively reducing cooling dead zones. This design significantly improves cooling uniformity, reduces material performance fluctuations caused by excessively rapid or slow local cooling, and accelerates the overall cooling rate, shortening the cooling time. Using the sagger conveying system of this application, the material temperature can be reduced from above 150°C to below 80°C during transport.

[0050] This embodiment of the application adopts an integrated design of cooling chamber 210 and gas channel 220, which can provide cooling to the protective gas through the cooling medium in cooling chamber 210, thereby reducing the number of protective gas sources and improving the cooling effect while effectively reducing equipment purchase costs. At the same time, the operating cost of the cooling medium is much lower than the cost of continuous supply of protective gas, which can reduce production energy consumption and long-term operating costs.

[0051] The cooling chamber 210 of this application embodiment can control the temperature of the cooling medium more precisely through an external cooling system. Even in high-temperature environments in summer, it can maintain a relatively stable cooling capacity through active cooling, reducing the weakening of the cooling effect as the temperature of the protective gas rises with the environment.

[0052] The cooling component 200 in this embodiment can lower the material temperature, reducing direct contact between high-temperature materials and downstream crushing and conveying equipment, thus reducing equipment failure due to high temperatures and the risk of aging and damage to pipelines and flexible connections. Simultaneously, it reduces the risk of ceramic patch adhesive detaching from the inner wall of the positive pressure conveying pipeline due to high-temperature failure, lowers the probability of metal foreign object generation and system damage, improves product safety and production capacity, and enhances the operational stability of subsequent equipment.

[0053] According to the sagger conveying system provided in the embodiments of this application, by setting a cooling element 200 in the transport channel 110, and using the cooling chamber 210 to connect with the external cooling system to achieve active heat exchange cooling, the protective gas delivered to the transport channel 110 by the gas channel 220 can achieve enveloping protection and enveloping cooling of the sagger 20, forming a dual cooling structure. This can significantly reduce the temperature of the material within a limited transport distance, improve the cooling uniformity, performance stability and safety of the material, reduce thermal damage to downstream equipment, and improve the economy of the sagger conveying system.

[0054] In lithium-ion battery cathode materials, related technologies introduce protective gas during material transportation to reduce material degradation caused by the reaction of high-temperature materials with water vapor or CO2. Simultaneously, the flow of protective gas assists in cooling the materials within the crucible. Taking ternary cathode materials as an example, the protective gas used in production is typically a dry, decarbonized gas. However, as the ambient temperature rises, the adsorption efficiency of the adsorption column decreases, and the moisture content in the protective atmosphere exhibits periodic fluctuations, causing the dew point in the transport track to exceed the standard. Currently, there is no relevant solution.

[0055] In some embodiments of this application, such as Figure 3 As shown, the gas channel 220 includes an inlet section 221 near the inlet 223 and an outlet section 222 near the outlet 224. The wall of the inlet section 221 is made of a hydrophobic and thermally conductive material, and the wall of the outlet section 222 is made of a reversible carbon dioxide adsorption material.

[0056] In this embodiment, the gas channel 220 has a segmented structure design.

[0057] The inlet section 221 of the gas passage 220 is close to the air inlet 223 and is used to receive the protective gas that has just entered the gas passage 220. It is the initial section for the protective gas to flow in the gas passage 220.

[0058] The wall of the inlet section 221 is made of a hydrophobic and thermally conductive material. This material is hydrophobic, meaning it repels or reduces the adhesion of water, thus reducing the condensation and residue of water on the wall of the inlet section 221; at the same time, this material has high thermal conductivity, which enables efficient heat transfer.

[0059] In this way, by selecting a hydrophobic and thermally conductive material for the wall of the inlet section 221, on the one hand, the hydrophobic properties can be used to reduce the condensation of trace amounts of water vapor that may be carried in the protective gas on the wall of the inlet section 221; on the other hand, the thermally conductive properties can be used to facilitate the cooling medium in the cooling chamber 210 to cool the protective gas that has just entered the gas channel 220.

[0060] The outlet section 222 of the gas passage 220, which is close to the gas outlet 224, is a section used to guide the protective gas to the transport passage 110.

[0061] The wall of the outlet section 222 is made of a reversible carbon dioxide adsorption material. This material can reduce trace amounts of carbon dioxide impurities that may be mixed into the protective gas. Under high-temperature conditions, carbon dioxide may react chemically with materials such as ternary cathode materials, leading to material performance degradation. Through the adsorption effect of the wall of the outlet section 222, carbon dioxide can be reduced in the protective gas ejection channel 220. At the same time, the reversible adsorption characteristic of this material allows its adsorption capacity to be restored through simple regeneration, achieving green and recyclable reuse, reducing consumable replacement costs, adapting to long-term stable production needs, and improving the environmental protection and economy of the crucible conveyor system.

[0062] In some embodiments of this application, the wall of the inlet section 221 may include at least one of high-temperature resistant glass, an ultrathin hydrophobic coating, or a nano-ceramic coating.

[0063] In this embodiment, the wall of the inlet section 221 can be made of high-temperature resistant glass, ultra-thin hydrophobic coating or nano-ceramic coating.

[0064] Alternatively, the wall surface of the inlet section 221 can also be made of a combination of the above-mentioned materials to further enhance the functional effect and adapt to different working conditions. For example, an ultra-thin hydrophobic coating can be applied to the surface of high-temperature resistant glass, or a nano-ceramic coating can be applied to the surface of high-temperature resistant glass.

[0065] High-temperature resistant glass is a special type of glass with excellent high-temperature stability. It can maintain its structural integrity under high-temperature conditions and hardly softens, deforms, or cracks. At the same time, it has certain hydrophobicity and thermal conductivity, and can be adapted to the temperature environment of the gas channel 220 inlet section 221 receiving the initial protective gas.

[0066] Ultrathin hydrophobic coating is a functional coating with an extremely thin thickness, such as micrometers. It can be applied to the surface of the substrate on the wall of the inlet section 221. The core characteristics of this coating are moisture repellency, reduced water vapor adhesion, and minimal space occupation of the gas channel 220, thus facilitating smooth gas flow.

[0067] Nano-ceramic coating is a coating material with nano-sized ceramic particles as its core component, possessing high thermal conductivity, high temperature resistance, and hydrophobicity. After application, the nano-ceramic coating forms a dense protective layer on the wall of the inlet section 221, simultaneously achieving both thermal conductivity and hydrophobicity.

[0068] All three materials are hydrophobic, which can effectively inhibit the condensation of trace amounts of water vapor carried in the protective gas on the wall surface, reduce the amount of condensed water sprayed onto the high-temperature material with the protective gas, reduce the reaction between water and material leading to performance degradation, and also reduce the erosion of the channel wall by water.

[0069] Both the high-temperature resistant glass and the nano-ceramic coating have a certain thermal conductivity, which facilitates the cooling medium in the cooling chamber 210 to cool the protective gas that has just entered the gas channel 220, thereby improving the subsequent cooling effect of the protective gas; the ultra-thin hydrophobic coating is extremely thin and will not significantly affect the thermal conductivity of the substrate.

[0070] It should be noted that the wall material of the inlet section 221 includes, but is not limited to, the three types mentioned above. Other materials with high temperature resistance, hydrophobicity and thermal conductivity can also be used.

[0071] In actual implementation, the selection of the 221 material in the inlet section can be made according to the specific working conditions of the production line, so that the material function matches the protective gas delivery and cooling effect, as well as the material protection requirements.

[0072] In some embodiments of this application, the wall of the outlet section 222 may include at least one of amine-functionalized materials, metal-organic framework materials, zeolite molecular sieves, or nanoporous carbon materials.

[0073] In this embodiment, the wall of the outlet section 222 can be made of amine-functionalized materials, metal-organic framework materials, zeolite molecular sieves, or nanoporous carbon materials.

[0074] Alternatively, the walls of the outlet section 222 can also be made of a combination of the above-mentioned materials, which can further enhance the functional effect and adapt to different working conditions.

[0075] Amine-functionalized materials are materials in which amine functional groups are introduced onto the surface of a substrate through chemical modification. These amine functional groups can specifically bind to carbon dioxide, thereby achieving selective adsorption of carbon dioxide.

[0076] Metal-organic frameworks are porous crystalline materials composed of metal ions or metal clusters and organic ligands. They have the characteristics of large specific surface area and adjustable pore size, and have a high adsorption capacity for carbon dioxide.

[0077] Zeolite molecular sieves are crystalline aluminosilicate materials with regular pore structures. They can selectively adsorb carbon dioxide based on molecular size, exhibiting good adsorption performance and strong stability.

[0078] Nanoporous carbon materials are carbon materials with nanoscale porous structures, large specific surface area and high adsorption capacity. Their adsorption capacity for carbon dioxide can be enhanced through physical adsorption or chemical modification.

[0079] All four materials mentioned above have excellent adsorption capacity for carbon dioxide, and most of them are selective adsorption. They can reduce the amount of trace carbon dioxide impurities mixed in before the protective gas is ejected from the gas channel 220, thereby reducing the chemical reaction between carbon dioxide and materials at high temperatures and reducing the risk of product deterioration caused by impurity gases.

[0080] Adsorbed carbon dioxide can be desorbed through methods such as hot air desorption and high-temperature water desorption. Metal-organic frameworks, zeolite molecular sieves, and nanoporous carbon materials are best suited for hot air desorption, as this method rapidly breaks down adsorption forces and avoids the influence of moisture on material properties. Amine-functionalized materials and some modified zeolite molecular sieves can be desorbed using high-temperature water, which can uniformly transfer heat and help weaken the adsorption bonds, thus matching their material properties. In this way, the above four materials can restore their adsorption capacity, enabling repeated use without frequent material replacement, reducing consumable costs and maintenance workload.

[0081] Metal-organic frameworks, zeolite molecular sieves, and nanoporous carbon materials all possess porous structures, while amine-functionalized materials can be coated into thin films. The selection of these materials does not excessively hinder the smooth flow of the protective gas, ensuring a certain level of adsorption and purification effect while maintaining a relatively stable supply of protective gas, thus reducing the impact of excessive channel resistance on the cooling effect of the protective gas.

[0082] The adsorption properties of the above four materials can be adapted to different temperature, pressure and carbon dioxide concentration conditions, and they can be used in combination. Whether it is the removal of low-concentration carbon dioxide impurities or the efficient adsorption under high temperature conditions, a suitable solution can be found.

[0083] It should be noted that the wall material of the outlet section 222 includes, but is not limited to, the four types mentioned above. Other materials with high carbon dioxide adsorption capacity, high temperature resistance and compatibility with regeneration processes may also be used.

[0084] In actual implementation, the selection of material 222 for the outlet section can be made according to the specific working conditions of the production line, so that the material function matches the protective gas delivery and cooling effect, as well as the material protection requirements.

[0085] In some embodiments of this application, such as Figure 3 As shown, the gas channel 220 is curved or bent.

[0086] In this embodiment, the curved shape refers to the gas channel 220 having a smooth, arc-shaped transition without obvious sharp angles. The inner wall of the curved gas channel 220 is continuous and smooth, allowing the protective gas to flow along a smooth trajectory. For example, the curved shape can be a spiral shape, where the gas channel 220 extends along the central axis in a continuous and circular smooth curve, forming a spiral structure similar to a spring, which can significantly extend the channel length within a very small space. Of course, the curved shape can also be a "U" shape or an "S" shape, etc.

[0087] The zigzag shape refers to the gas channel 220 being formed by connecting several straight segments with specific angles, with obvious sharp corners and transitions. The inner wall of the channel transitions at the turning points, and the gas needs to flow along the zigzag trajectory within the channel.

[0088] The aforementioned curved or bent gas channel 220 extends the time the protective gas spends within it, enhancing its cooling and purification effects. Compared to a straight gas channel 220, the curved and bent shapes significantly increase the actual channel length within a limited installation space, allowing the protective gas more time to exchange heat with the cooling gas in the cooling chamber 210, thus improving the cooling effect. Simultaneously, this design also ensures sufficient contact between the protective gas and the adsorbent material on the outlet section 222 wall, improving the removal efficiency of impurities such as carbon dioxide.

[0089] The curved and bent gas channel 220 has a larger contact area with the cooling medium inside the cooling chamber 210 compared to a straight channel. The larger contact area can accelerate the heat transfer rate, allowing the protective gas to absorb cold energy more quickly within the gas channel 220, which is beneficial to improving the cooling efficiency of the material.

[0090] Furthermore, the cooling component 200 is integrated into at least one side of the transport channel 110, where the internal space is limited. The curved and bent shapes can maximize the use of three-dimensional space, allowing for the rational planning of protective airflow paths without increasing the volume of the cooling component 200, thus meeting the compact layout requirements of automated production lines.

[0091] In some embodiments of this application, such as Figure 3 As shown, the crucible conveying system may include a condensate collector 300; the gas passage 220 has an outlet 225 between the inlet section 221 and the outlet section 222, and the condensate collector 300 is connected to the outlet 225.

[0092] In this embodiment, the condensate collector 300 is a component for receiving and collecting condensate.

[0093] The outlet 225 is a specific opening provided on the gas passage 220 to discharge condensate generated within the gas passage 220, located in the area between the inlet section 221 and the outlet section 222. The gas passage 220 may have an outlet 225 at at least one low point of a bend or twist between the inlet section 221 and the outlet section 222, so that condensate can be naturally guided into the outlet 225 by gravity.

[0094] The condensate collector 300 is directly connected to the outlet 225 or connected through pipes or other connecting structures to form a path for the discharge and collection of condensate.

[0095] When the protective gas enters the inlet section 221 through the inlet 223, the higher temperature protective gas comes into contact with the lower temperature inner wall of the inlet section 221 and cools down. The moisture entrained in the gas liquefies and forms droplets. Since the inner wall of the inlet section 221 is made of hydrophobic material, the droplets do not adhere to the inner wall of the inlet section 221. Instead, they slide down to the outlet 225 between the inlet section 221 and the outlet section 222, and are then collected and discharged through the connected condensate collector 300. This reduces the moisture content in the protective gas and reduces the risk of moisture entering subsequent sections and contaminating high-temperature materials or affecting the adsorption performance of the wall material of the outlet section 222.

[0096] This design eliminates the need for additional consumables to absorb moisture from the protective gas, and the condensate collector 300 can be used in a green, recyclable manner, improving the environmental friendliness and economy of the crucible conveying system.

[0097] The condensate collector 300 collects condensate in a centralized manner, and then it can be discharged or treated in a unified manner, such as by filtration or drying, to reduce the pollution of the production environment caused by condensate flow.

[0098] In some embodiments of this application, such as Figures 1-3 As shown, the crucible conveying system may include: At least one temperature sensor 400 is used to measure the temperature of a corresponding area in the transport channel 110; At least one dew point sensor 500 is used to measure the dew point of a corresponding area in the transport channel 110; The protective gas flow regulating device 600 is used to regulate the gas flow in the gas channel 220; Cooling medium flow rate regulating device 700 is used to regulate the medium flow rate of cooling chamber 210; The controller is electrically connected to the temperature sensor 400, the dew point sensor 500, the protective gas flow regulator 600, and the cooling medium flow regulator 700, and is used to control the protective gas flow regulator 600 and the cooling medium flow regulator 700 based on the detection signals of the temperature sensor 400 and the dew point sensor 500.

[0099] In this embodiment, the sagger conveying system may include a temperature sensor 400, a dew point sensor 500, a protective gas flow regulating device 600, a cooling medium flow regulating device 700, and a controller.

[0100] Temperature sensor 400 is a device used to detect the temperature of a specific area and convert the temperature signal into an electrical signal. It is suitable for high-temperature process environments and can stably collect temperature data within the transport channel 110. Figure 2 As shown, the temperature sensor 400 can be installed on the top wall of the transport channel 110. Of course, the temperature sensor 400 can also be installed on other walls of the transport channel 110. The temperature sensor 400 can be a contact temperature sensor or a non-contact temperature sensor, such as an infrared thermometer.

[0101] Temperature sensor 400 may include at least one, and multiple temperature sensors 400 may be installed in different areas of transport channel 110 according to temperature monitoring requirements. The installation position of temperature sensor 400 can be matched with the monitoring area to facilitate real-time acquisition of temperature data of the corresponding area within transport channel 110, providing temperature basis for subsequent control.

[0102] The dew point sensor 500 is used to detect the temperature at which moisture in a gas condenses into liquid water, i.e., the dew point, indirectly reflecting the humidity of the gas. It can convert the dew point signal into an electrical signal to capture the moisture content of the protective gas within the transport channel 110. Figure 2As shown, the dew point sensor 500 can be installed on the top wall of the transport channel 110. Of course, the dew point sensor 500 can also be installed on other walls of the transport channel 110.

[0103] The dew point sensor 500 may include at least one, and multiple dew point sensors 500 may be installed in different areas of the transport channel 110 according to dew point monitoring requirements. The installation position of the dew point sensor 500 can be matched with the monitoring area to facilitate the real-time collection of dew point data of the corresponding area within the transport channel 110, indirectly obtaining gas humidity information and providing a basis for subsequent moisture control.

[0104] The protective gas flow regulating device 600 is a component used to control the flow rate and volume of protective gas within the gas passage 220. It can increase or decrease the protective gas supply based on a control signal, thereby regulating the protective gas flow rate. The protective gas flow regulating device 600 includes, but is not limited to, flow regulating valves, proportional electromagnetic regulating valves, and pneumatic regulating valves.

[0105] The cooling medium flow regulating device 700 is a component used to control the flow rate and volume of the cooling medium inside the cooling chamber 210. It can increase or decrease the supply of cooling medium according to a control signal to regulate the flow rate of the cooling medium. The cooling medium flow regulating device 700 includes, but is not limited to, regulating valves, proportional solenoid regulating valves, and pneumatic regulating valves.

[0106] The controller is a core control component with signal receiving, analysis and processing, and command output functions, serving as the central hub for the coordinated operation of various components. The controller establishes signal transmission channels with the temperature sensor 400, dew point sensor 500, protective gas flow regulator 600, and cooling medium flow regulator 700 via electrical connections. The controller receives temperature signals from the temperature sensor 400 and dew point signals from the dew point sensor 500, analyzes and processes these signals (e.g., determining whether the current temperature and humidity meet preset standards), and outputs corresponding control commands to the protective gas flow regulator 600 and cooling medium flow regulator 700 based on the analysis results, thereby achieving automated control.

[0107] By combining temperature sensor 400 and dew point sensor 500, temperature and protective gas humidity data within transport channel 110 can be collected in real time and with relatively high accuracy. The controller links the sensors and adjustment devices, automatically adjusting the protective gas flow rate and cooling medium flow rate based on real-time monitoring data. For example, when temperature sensor 400 detects excessively high regional temperatures, the controller can instruct cooling medium flow rate adjustment device 700 to increase flow rate and improve cooling efficiency, while simultaneously instructing protective gas flow rate adjustment device 600 to fine-tune the flow rate to stabilize the protective gas flow. When dew point sensor 500 detects excessively high humidity, the controller can instruct cooling medium flow rate adjustment device 700 to increase flow rate, enhancing the cooling effect of cooling chamber 210 on the protective gas within gas channel 220, further reducing the protective gas temperature, promoting condensation of moisture in the protective gas into liquid water, which is then discharged through condensate collector 300, thereby reducing the humidity of the protective gas.

[0108] In some embodiments of this application, such as Figure 1 As shown, there are multiple temperature sensors 400 and dew point sensors 500, and these multiple temperature sensors 400 and dew point sensors 500 are distributed at least at the entrance, middle section and exit of the transport channel 110.

[0109] In this embodiment, multiple temperature sensors 400 and multiple dew point sensors 500 can be arranged at the entrance, middle section, and exit of the transport channel 110 according to monitoring needs. For example, as Figure 1 and Figure 2 As shown, the temperature sensor 400 and the dew point sensor 500 can be arranged in combination; or, the temperature sensor 400 and the dew point sensor 500 can be arranged separately.

[0110] The entrance to transport channel 110 corresponds to the initial area where the sagger 20 and high-temperature materials enter transport channel 110.

[0111] The interior of transport channel 110 corresponds to the core cooling operation area within transport channel 110.

[0112] The outlet of transport channel 110 corresponds to the sagger 20 and the material leaving the terminal area of ​​transport channel 110 after cooling.

[0113] Temperature sensor 400 and dew point sensor 500 in the inlet area can collect the initial temperature and humidity of the sagger 20 and materials entering the transport channel 110 in real time, providing reference data for subsequent control. Temperature sensor 400 and dew point sensor 500 in the middle section can monitor the dynamic changes in temperature and humidity during the transport cooling process to determine whether the cooling effect meets the preset standard. Temperature sensor 400 and dew point sensor 500 in the outlet area can detect the final temperature and humidity after cooling is completed, verifying whether the cooling and dehumidification effects meet the standards. Full coverage monitoring of the three types of areas reduces the misjudgment of operating conditions caused by monitoring a single area, and enables dynamic detection of the material cooling process, collecting temperature and dew point changes of the sagger 20 and materials.

[0114] The controller can perform differentiated regulation based on the data detected by the temperature sensors 400 and dew point sensors 500 in the three regions mentioned above. For example, if the temperature sensor 400 in the inlet region detects that the initial temperature is too high, it can instruct the cooling medium flow regulating device 700 to increase the flow rate of the cooling medium in advance to improve the initial cooling intensity; if the dew point sensor 500 in the middle region detects that the local humidity is too high, it can adjust the flow rate of the cooling medium in the internal region cooling component 200 to promote the condensation of moisture in the protective gas in the gas channel 220; if the temperature sensor 400 or the dew point sensor 500 in the outlet region detects that the temperature or humidity is too high, it can perform safety measures on the sagger 20, forming a full-process control.

[0115] Operating conditions may vary in different areas. The multi-regional distribution of the temperature sensor 400 and dew point sensor 500 allows them to collect accurate data tailored to the specific operating conditions of each region. Based on the differentiated data from each region, the controller can specifically adjust the protective gas flow rate and cooling medium flow rate for that region, reducing energy waste or insufficient cooling and optimizing energy utilization efficiency while improving cooling performance.

[0116] The multi-zone distributed temperature sensors 400 and dew point sensors 500 can quickly locate abnormal areas. If the data from the temperature sensor 400 or dew point sensor 500 in a certain area is abnormal, such as the temperature in the middle section being too high or the humidity in the outlet area exceeding the standard, the corresponding cooling component 200 or material conveying fault can be quickly identified. This facilitates timely troubleshooting and repair by staff, reduces the risk of fault spread leading to damage to the entire production line, and improves the stability and reliability of system operation.

[0117] In some embodiments of this application, at least one of the bottom and sides of the transport channel 110 is provided with a plurality of cooling elements 200 arranged along a first direction X.

[0118] In this embodiment, multiple cooling elements 200 are provided at one or more locations along the first direction X on the bottom and sides of the transport channel 110. From the perspective of the arrangement area, it is not limited to a single location; multiple cooling elements 200 can be arranged along the first direction X on the bottom of the transport channel 110, or along the first direction X on the sides of the transport channel 110, or simultaneously on both the bottom and sides along the first direction X, depending on actual cooling requirements.

[0119] Multiple cooling elements 200 are arranged along the conveying direction, continuously cooling the sagger 20 and the material within it throughout its entire stroke from the inlet to the outlet. As the sagger 20 moves along the conveying direction, it remains within the range of cooling elements 200 that enhance cooling capacity. Compared to the localized cooling of a single cooling element 200, this arrangement reduces the risk of insufficient material cooling or excessively high local temperatures, improves the uniformity of cooling across the material, and enhances the stability of the cooling effect.

[0120] Multiple cooling components 200 distribute the cooling load, reducing the risk of damage or performance degradation to individual components due to prolonged high-load operation. Simultaneously, their dispersed arrangement along the conveying direction ensures more even heat exchange, reducing damage to the cooling medium pipelines caused by localized overcooling or overheating, extending the service life of the crucible conveying system, and lowering equipment maintenance costs.

[0121] In some embodiments of this application, such as Figure 2 As shown, at least one of the bottom and sides of the transport channel 110 is provided with a plurality of cooling elements 200 arranged perpendicular to the first direction X.

[0122] In this embodiment, one or more locations on the bottom and sides of the transport channel 110 are provided with multiple cooling elements 200 in a direction perpendicular to the first direction X. From the perspective of the arrangement area, it is not limited to a single location; multiple cooling elements 200 can be arranged in the direction perpendicular to the first direction X at the bottom of the transport channel 110, or in the direction perpendicular to the first direction X on the sides of the transport channel 110, or multiple cooling elements 200 can be arranged simultaneously in the direction perpendicular to the first direction X on both the bottom and sides.

[0123] Multiple cooling components 200 are arranged laterally along the direction perpendicular to the first direction X, which can basically cover the transverse cross-section of the sagger 20, such as the entire bearing surface at the bottom of the sagger 20 or the surrounding surface of the side. Compared with localized cooling at a single point, this arrangement can reduce temperature differences in different parts of the sagger 20 laterally, such as uneven cooling between the edge and the center, so that the high-temperature material cools down at basically the same transverse points, improving the consistency of the material's performance after cooling.

[0124] Multiple cooling components 200 distribute the cooling load, reducing the risk of damage or performance degradation to individual components due to prolonged high-load operation. Simultaneously, their dispersed arrangement along a direction perpendicular to the first direction X ensures more even heat exchange, reducing damage to the cooling medium pipelines caused by localized overcooling or overheating, extending the service life of the crucible conveying system, and lowering equipment maintenance costs.

[0125] The number of cooling components 200 arranged along a direction perpendicular to the first direction X can be flexibly adjusted according to the lateral dimensions of the sagger 20. For example, some cooling components 200 can be used for small-sized saggers 20, and all cooling components 200 can be used for large-sized saggers 20. Different production requirements can be adapted without changing the structure of the cooling components 200, thereby improving the versatility of the sagger conveying system for diverse production tasks and reducing equipment adaptation costs.

[0126] In some embodiments of this application, such as Figure 2 As shown, cooling components 200 are provided on the bottom wall of the transport channel 110 and on the two side walls extending along the first direction X. The outlet 224 of the gas channel 220 of the cooling component 200 on the bottom wall is used to spray protective gas onto the bottom surface of the sagger 20 inside the transport channel 110, and the outlet 224 of the gas channel 220 of the cooling component 200 on the side wall is used to spray protective gas onto the side surface of the sagger 20 inside the transport channel 110.

[0127] In this embodiment, cooling elements 200 are arranged on the bottom wall and the two side walls extending along the first direction X, forming a three-sided surrounding arrangement of the interior of the transport channel 110, rather than a single area or partial area arrangement, thereby increasing the supply of cooling capacity and protective gas. Compared to single-area cooling, this arrangement allows the multiple surfaces of the sagger 20 to exchange heat with the cooling elements 200 almost simultaneously, reducing the problem of local overheating, improving the overall cooling uniformity of the sagger 20 and the internal materials, and improving the stability of the material properties after cooling.

[0128] The air outlet 224 of the bottom wall cooling component 200 is oriented towards the bottom surface of the sagger 20, so that the protective gas acts directly on the bottom of the sagger 20; the air outlets 224 of the side wall cooling components 200 are respectively oriented towards the corresponding side of the sagger 20, so that the protective gas acts directly on the side of the sagger 20. This directional design can reduce the risk of protective gas waste or protective gas failure caused by deviation of the injection direction.

[0129] The directional design of the vent 224 reduces the irregular diffusion of the protective gas, allowing most of the protective gas to act directly on the surface of the crucible 20, reducing protective gas waste and improving the utilization rate of the protective gas.

The gas channel 220 includes an inlet section 221 and an outlet section 222. The inlet section 221 is close to the inlet 223, and the wall of the inlet section 221 is made of a hydrophobic and thermally conductive material.
