[0001] This application relates to the field of battery technology, and in particular to a battery material manufacturing equipment and a battery production equipment. Background Technology

[0002] With the development of new energy technologies, batteries are being used more and more widely, for example in mobile phones, laptops, electric vehicles, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes, and power tools.

[0003] Battery materials are typically produced using battery material manufacturing equipment. The production process includes batching, sintering, crushing, coating, and packaging. The energy consumption and reliability of this manufacturing equipment significantly impact the overall economic efficiency of the battery. Therefore, effectively reducing energy consumption and improving reliability are pressing issues in battery technology. Utility Model Content

[0004] In view of the above problems, this application provides a battery material manufacturing equipment and a battery production equipment, which can effectively reduce production energy consumption and improve reliability.

[0005] In a first aspect, embodiments of this application provide a battery material manufacturing apparatus, comprising a sintering device, a first exhaust gas discharge pipe, a protective gas storage device, and a protective gas delivery pipe. The sintering device is used to sinter materials. The first exhaust gas discharge pipe is connected to the sintering device and is used to discharge the exhaust gas generated by the sintering device. The protective gas storage device is disposed upstream of the sintering device and is used to provide protective gas. The protective gas delivery pipe is connected between the sintering device and the protective gas storage device, and at least a portion of the protective gas delivery pipe is disposed inside the first exhaust gas discharge pipe.

[0006] The above-mentioned technical solution effectively reduces overall production energy consumption by reusing the thermal energy of the exhaust gas generated by the sintering unit to heat the protective gas. Furthermore, compared to installing an additional heating device on the protective gas delivery pipeline, this technical solution also reduces the vulnerability of the heating device, thereby improving the reliability of the battery material manufacturing equipment.

[0007] In some embodiments of the first aspect, at least a portion of the protective gas delivery pipe located inside the first exhaust gas discharge pipe is tortuously arranged.

[0008] By tortuously configuring at least a portion of the protective gas delivery pipe located inside the first exhaust gas discharge pipe, the extension length and surface area of ​​this portion of the protective gas delivery pipe can be increased, thereby extending the heating time of the exhaust gas on this portion of the protective gas delivery pipe and improving the heating effect of the protective gas.

[0009] In some embodiments of the first aspect, at least a portion of the protective gas delivery pipe located inside the first exhaust gas discharge pipe is spirally arranged, and the axis of the spiral is parallel to the extension direction of the first exhaust gas discharge pipe.

[0010] By configuring at least a portion of the protective gas delivery pipe located inside the first exhaust gas pipe as a spiral shape, it is possible to increase the extension length and surface area of ​​this portion of the protective gas delivery pipe while reducing the impact on the flow velocity of the protective gas inside this portion of the protective gas delivery pipe, which helps to improve the production efficiency of battery material manufacturing equipment.

[0011] In some embodiments of the first aspect, the protective gas delivery pipe located inside the first exhaust gas discharge pipe includes at least one first part and at least one second part, the first part extending along a first direction and the second part extending along a second direction, the first part being connected to the second part, and the first direction and the second direction intersecting.

[0012] The above technical solution, by setting the protective gas delivery pipe located inside the first exhaust gas pipe as a first part and a second part with different extension directions, can increase the extension length and surface area of ​​this part of the protective gas delivery pipe, while also increasing the flexibility of its setting, reducing the overall manufacturing difficulty of the battery material manufacturing equipment, and helping to reduce costs.

[0013] In some embodiments of the first aspect, the protective gas delivery pipe located inside the first exhaust gas pipe further includes at least one third portion, the third portion extending along a third direction, each third portion being connected to at least one of the first portion and the second portion, the first direction, the second direction and the third direction intersecting each other.

[0014] The above technical solution, by further introducing a third part, enables the protective gas delivery pipe located inside the first exhaust gas discharge pipe to form a three-dimensional bent structure, which can improve the utilization rate of this part of the protective gas delivery pipe to the internal space of the first exhaust gas discharge pipe, thereby further increasing the extension length and surface area of ​​this part of the protective gas delivery pipe, and thus further improving the heating effect of the protective gas.

[0015] In some embodiments of the first aspect, the first exhaust gas discharge pipe includes a first main section, a second main section, and a branch section. The branch section is connected between the first and second main sections. The first main section is connected to the branch section and the sintering device. At least a portion of the protective gas conveying pipe is disposed inside the second main section. The branch section includes a first pipeline and a second pipeline, both of which are connected between the first and second main sections and are arranged in parallel. The first exhaust gas discharge pipe also includes a first control element and a second control element. The first control element is disposed in the first pipeline and used to control the on / off state of the first pipeline, and the second control element is disposed in the second pipeline and used to control the on / off state of the second pipeline.

[0016] The above technical solution introduces a first pipeline and a second pipeline arranged in parallel, which can be used as a backup. When the other pipeline fails and maintenance is required, the exhaust gas can continue to flow through the backup pipeline to heat the protective gas. This improves the continuity of exhaust gas heating of the protective gas and reduces the adverse effects of downtime maintenance due to pipeline failure.

[0017] In some embodiments of the first aspect, the first conduit includes a first pipe section, a second pipe section, and a third pipe section. The first pipe section is fixed to a first main section, the third pipe section is fixed to a second main section, the second pipe section is detachably connected between the first pipe section and the third pipe section, and a first control element is disposed on the first pipe section and used to control the on / off state of the first pipe section.

[0018] The above technical solution, by setting the second pipe section to be detachably connected between the first pipe section and the third pipe section, facilitates the repair or cleaning of the first pipe section when a fault occurs, thereby improving the overall maintenance convenience of the first exhaust gas discharge pipe.

[0019] In some embodiments of the first aspect, the first conduit includes a first quick connector, and a second conduit is detachably connected to the first conduit via the first quick connector; and / or, the first conduit includes a second quick connector, and a second conduit is detachably connected to a third conduit via the second quick connector.

[0020] It can improve the efficiency of installation and disassembly between the second tube section and the first tube section, thereby improving the convenience of assembly or maintenance.

[0021] In some embodiments of the first aspect, the first exhaust gas discharge pipe further includes a third control element disposed in the third pipe section and used to control the on / off state of the third pipe section.

[0022] The above technical solution, by further introducing a third control component, can reduce the risk of residual exhaust gas in the second section flowing back out of the third section when the second pipe section is disassembled, repaired, or cleaned, thereby reducing environmental pollution and harm to the health of maintenance personnel.

[0023] In some embodiments of the first aspect, a first filter is provided inside the second pipeline for filtering impurities in the exhaust gas inside the second pipeline.

[0024] The first filter in the above technical solution can intercept impurities in the exhaust gas discharged into the first exhaust gas pipeline, reducing the risk of the heating of the protective gas delivery pipeline being affected by the accumulation of impurities in the pipeline. In addition, the first filter is installed inside the second pipe section, and the detachable design of the second pipe section facilitates the replacement and maintenance of the first filter.

[0025] In some embodiments of the first aspect, the battery material manufacturing apparatus further includes a detection device connected to the first section, the detection device being used to detect the fluid pressure inside the first section.

[0026] The above-mentioned technical solution helps to keep the system operating within the predetermined pressure range. On the other hand, it enables timely switching between the first pipeline and the second pipeline based on the fluid pressure inside the first section, thereby reducing the risk of production accidents caused by abnormal pressure.

[0027] In some embodiments of the first aspect, the battery material manufacturing equipment further includes a filtration device disposed inside the first exhaust gas discharge pipe and located upstream of a protective gas delivery pipe disposed inside the first exhaust gas discharge pipe.

[0028] The filtration device of the above technical solution can intercept impurities in the exhaust gas in the first exhaust gas discharge pipe, reducing the risk of the heating of the protective gas delivery pipe caused by the accumulation of impurities in the pipe.

[0029] In some embodiments of the first aspect, the battery material manufacturing equipment further includes an incineration device and a second exhaust gas discharge pipe. The incineration device is located downstream of the sintering device, and the second exhaust gas discharge pipe is connected between the sintering device and the incineration device. The incineration device is connected between the first exhaust gas discharge pipe and the second exhaust gas discharge pipe, and is used to incinerate the exhaust gas generated by the sintering device.

[0030] The above technical solution introduces an incineration device to first incinerate the exhaust gas generated by the sintering device. The incinerated exhaust gas then enters the first exhaust gas discharge pipe to heat the protective gas. This process not only incinerates and vaporizes some combustible impurities in the exhaust gas, reducing the risk of impurities adhering to the inner wall of the first exhaust gas discharge pipe and causing blockage, but also extends the service life of the pipe. Furthermore, it further increases the temperature of the exhaust gas entering the first exhaust gas discharge pipe, thereby enhancing the heating effect of the exhaust gas on the protective gas.

[0031] In some embodiments of the first aspect, the battery material manufacturing equipment further includes an exhaust gas treatment device, which is located downstream of the incineration device. A first exhaust gas discharge pipe is connected between the incineration device and the exhaust gas treatment device, and the exhaust gas treatment device is used to purify the exhaust gas in the first exhaust gas discharge pipe.

[0032] The above technical solution reduces the risk of environmental pollution by introducing an exhaust gas treatment device to purify the exhaust gas in the first exhaust gas discharge pipe.

[0033] Secondly, this application provides a battery production system, which includes the battery material manufacturing equipment provided in any embodiment of the first aspect.

[0060] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0061] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0063] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

The battery cell may be cylindrical, flat, cuboid, or other shapes, etc., and the embodiments of this application are not limited thereto.

[0067] With the development of new energy technologies, batteries are being used more and more widely, for example in mobile phones, laptops, electric vehicles, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes, and power tools.

[0068] Battery materials are typically produced using battery material manufacturing equipment. The production process includes batching, sintering, crushing, coating, and packaging. The energy consumption and reliability of this manufacturing equipment significantly impact the overall economic efficiency of the battery.

[0069] Battery materials can be positive electrode materials, negative electrode materials, or separators, etc. Sintering is a crucial step in the battery material production process. During sintering, a protective gas needs to be added to the sintering apparatus to protect the atmosphere inside and reduce the risk of oxidation of the materials located within the apparatus. This protective gas can be an inert gas such as nitrogen, helium, or argon.

[0070] Before the protective gas enters the sintering unit, it needs to be heated to reduce its impact on the internal temperature of the sintering unit. Currently, the common method is to install electric heat tracing on the protective gas delivery pipeline to heat the pipeline, and then use the heat from the pipeline to heat the protective gas. However, due to limitations in the heating effect and material properties of electric heat tracing, its heating effect is not ideal. Depending on the winding specifications, the protective gas is heated unevenly, resulting in high energy consumption in battery material manufacturing equipment. Furthermore, electric heat tracing is significantly affected by humid environments such as moisture, leading to lower reliability of the battery material manufacturing equipment.

[0071] Based on the above considerations, this application designs a battery material manufacturing equipment, which includes a sintering device, a first exhaust gas discharge pipe, a protective gas storage device, and a protective gas delivery pipe. The sintering device is used to sinter materials. The first exhaust gas discharge pipe is connected to the sintering device and is used to discharge the exhaust gas generated by the sintering device. The protective gas storage device is located upstream of the sintering device and is used to provide protective gas. The protective gas delivery pipe is connected between the sintering device and the protective gas storage device, and at least a portion of the protective gas delivery pipe is disposed inside the first exhaust gas discharge pipe.

[0072] The exhaust gas generated by the sintering device can flow through the protective gas delivery pipe located inside the first exhaust gas discharge pipe. The heat of the exhaust gas can heat this part of the protective gas delivery pipe, and then conduct the heat to the protective gas inside the protective gas delivery pipe to heat the protective gas.

[0073] The above-mentioned technical solution effectively reduces overall production energy consumption by reusing the thermal energy of the exhaust gas generated by the sintering unit to heat the protective gas. Furthermore, compared to installing an additional heating device on the protective gas delivery pipeline, this technical solution also reduces the vulnerability of the heating device, thereby improving the reliability of the battery material manufacturing equipment.

[0074] Figure 1 This is a schematic diagram of the layout structure of a battery material manufacturing apparatus provided in some embodiments of this application.

[0075] like Figure 1As shown in the illustration, this application provides a battery material manufacturing apparatus, which includes a sintering device 10, a first exhaust gas discharge pipe 20, a protective gas storage device 30, and a protective gas delivery pipe 40. The sintering device 10 is used to sinter materials. The first exhaust gas discharge pipe 20 is connected to the sintering device 10 and is used to discharge the exhaust gas generated by the sintering device 10. The protective gas storage device 30 is disposed upstream of the sintering device 10 and is used to provide protective gas. The protective gas delivery pipe 40 is connected between the sintering device 10 and the protective gas storage device 30, and at least a portion of the protective gas delivery pipe 40 is disposed inside the first exhaust gas discharge pipe 20.

[0076] For example, the material can be a positive electrode material, a negative electrode material, or an additive, etc., and the sintering apparatus 10 can be used to perform high-temperature sintering treatment on the positive electrode material, negative electrode material, etc. of the battery. Sintering refers to the process of subjecting the original material to high-temperature hot pressing treatment to form a dense crystalline structure. The sintering process involves subjecting the material particles to thermal pressure, causing a liquid-phase chemical reaction on their surface, forming chemical bonds between the particles, thereby densifying the material.

[0077] The cathode material can be, but is not limited to, lithium phosphates, lithium transition metal oxides, and their respective modified compounds. Examples of lithium phosphates include, but are not limited to, at least one of lithium iron phosphate, lithium iron phosphate and carbon composites, lithium manganese phosphate, lithium manganese phosphate and carbon composites, lithium manganese iron phosphate, and lithium manganese iron phosphate and carbon composites. Examples of lithium transition metal oxides include, but are not limited to, at least one of lithium cobalt oxide, lithium nickel oxide, lithium manganese oxide, lithium nickel cobalt oxide, lithium manganese cobalt oxide, lithium nickel manganese oxide, lithium nickel cobalt manganese oxide, lithium nickel cobalt aluminum oxide, and their modified compounds.

[0078] The negative electrode material may include at least one of the following materials: artificial graphite, natural graphite, soft carbon, hard carbon, silicon-based materials, tin-based materials, and lithium titanate, etc. Silicon-based materials may be selected from at least one of elemental silicon, silicon oxide compounds, silicon-carbon composites, silicon-nitrogen composites, and silicon alloys. Tin-based materials may be selected from at least one of elemental tin, tin oxide compounds, and tin alloys.

[0079] During the sintering process, the sintering device 10 generates exhaust gas, which refers to the waste gas containing heat generated after the material is burned at high temperature.

[0080] The first exhaust gas discharge pipe 20 is used to discharge exhaust gas from the sintering apparatus 10. The first exhaust gas discharge pipe 20 may be directly connected to the sintering apparatus 10 or indirectly connected to the sintering apparatus 10 through other devices.

[0081] Optionally, the first exhaust pipe 20 may be, but is not limited to, a square pipe, a circular pipe, or a polygonal pipe.

[0082] Optionally, the first exhaust pipe 20 may be, but is not limited to, made of high-temperature resistant materials such as nickel-based alloys, stainless steel, or ceramics.

[0083] The protective gas delivery pipeline 40 is used to deliver the protective gas in the protective gas storage device 30 to the sintering apparatus 10. The protective gas delivery pipeline 40 can be directly connected between the sintering apparatus 10 and the protective gas storage device 30, or it can be indirectly connected between the sintering apparatus 10 and the protective gas storage device 30 through other devices.

[0084] The protective gas is used to protect the atmosphere inside the sintering apparatus 10 during the sintering process, reducing the risk of oxidation of the materials inside the sintering apparatus 10. The protective gas can be an inert gas such as nitrogen, helium, or argon.

[0085] In some examples, the protective gas is nitrogen, which is relatively inexpensive and helps reduce the production cost of battery materials.

[0086] At least a portion of the protective gas delivery pipe 40 is disposed inside the first exhaust gas discharge pipe 20. The exhaust gas generated by the sintering apparatus 10 can flow through the protective gas delivery pipe 40 disposed inside the first exhaust gas discharge pipe 20. The heat of the exhaust gas can heat this portion of the protective gas delivery pipe 40, thereby transferring the heat to the protective gas inside the protective gas delivery pipe 40 to heat the protective gas.

[0087] For example, a portion of the protective gas delivery pipe 40 may be located inside the first exhaust gas discharge pipe 20, while another portion may be located outside the first exhaust gas discharge pipe 20; alternatively, the entire protective gas delivery pipe 40 may be located inside the first exhaust gas discharge pipe 20.

[0088] Optionally, the protective gas delivery pipe 40 can be, but is not limited to, a square pipe, a circular pipe, or a polygonal pipe.

[0089] Optionally, the protective gas delivery pipe 40 may be, but is not limited to, made of high-temperature resistant materials such as nickel-based alloys, stainless steel, or ceramics.

[0090] The above-described technical solution effectively reduces overall production energy consumption by reusing the thermal energy of the exhaust gas generated by the sintering unit 10 to heat the protective gas. Furthermore, compared to installing an additional heating device on the protective gas delivery pipeline 40 to heat the protective gas, the above-described technical solution also reduces the vulnerability of the heating device, thereby improving the reliability of the battery material manufacturing equipment.

[0091] In some embodiments, the battery material manufacturing equipment further includes a detection device connected to the first exhaust gas discharge pipe 20, which is used to detect the fluid pressure inside the first exhaust gas discharge pipe 20.

[0092] The detection device can monitor the fluid pressure inside the first exhaust gas discharge pipe 20 in real time, which helps to keep the system operating within the predetermined pressure range, thereby reducing the risk of production accidents caused by abnormal pressure.

[0093] In some examples, the detection device includes a pressure gauge, which is inexpensive and helps reduce the overall cost of battery material manufacturing equipment.

[0094] In some embodiments, the battery material manufacturing equipment further includes a filtration device disposed inside the first exhaust gas discharge pipe 20 and located upstream of the protective gas delivery pipe 40 disposed inside the first exhaust gas discharge pipe 20.

[0095] The filtration device is used to filter impurities in the exhaust gas within the first exhaust gas discharge pipe 20. For example, the impurities in the exhaust gas may be, but are not limited to, particles or dust. The filtration device may be, but is not limited to, a fiber filter, an activated carbon filter, or a metal filter.

[0096] The filtration device of the above technical solution can intercept impurities in the exhaust gas in the first exhaust gas discharge pipe 20, reducing the risk of the heating of the protective gas delivery pipe 40 caused by the accumulation of impurities in the pipe.

[0097] In some examples, the filtering device includes at least one of a first filter 61 and a second filter 62.

[0098] In some embodiments, at least a portion of the protective gas delivery pipe 40 located inside the first exhaust gas discharge pipe 20 is tortuously arranged.

[0099] For example, a portion of the protective gas delivery pipe 40 located inside the first exhaust gas discharge pipe 20 may be tortuous, or the entire protective gas delivery pipe 40 located inside the first exhaust gas discharge pipe 20 may be tortuous. Here, tortuous configuration can be understood as bending and / or twisting.

[0100] By tortuously arranging at least a portion of the protective gas delivery pipe 40 located inside the first exhaust gas discharge pipe 20, the extension length and surface area of ​​this portion of the protective gas delivery pipe 40 can be increased, thereby extending the heating time of the exhaust gas on this portion of the protective gas delivery pipe 40 and improving the heating effect of the protective gas.

[0101] Figure 2This is a partial structural diagram of a protective gas delivery pipe 40 disposed inside a first exhaust gas discharge pipe 20 in a battery material manufacturing apparatus provided in some embodiments of this application.

[0102] Continue to refer to Figure 2 In some embodiments, at least a portion of the protective gas delivery pipe 40 located inside the first exhaust gas discharge pipe 20 is spirally arranged, and the axis of the spiral is parallel to the extension direction of the first exhaust gas discharge pipe 20.

[0103] Understandably, a spiral-shaped pipe has a relatively small impact on the flow rate of the fluid inside.

[0104] Thus, by setting at least a portion of the protective gas delivery pipe 40 located inside the first exhaust gas pipe 20 to a spiral shape, it is possible to increase the extension length and surface area of ​​this portion of the protective gas delivery pipe 40 while reducing the impact on the flow velocity of the protective gas inside this portion of the protective gas delivery pipe 40, thereby helping to improve the production efficiency of the battery material manufacturing equipment.

[0105] Figure 3 This is a partial top view of the protective gas delivery pipe 40 disposed inside the first exhaust pipe 20 in another battery material manufacturing apparatus provided in some embodiments of this application. Figure 4 for Figure 3 A side view of the structure shown.

[0106] Continue to refer to Figures 3 to 4 In some embodiments, the protective gas delivery pipe 40 located inside the first exhaust gas discharge pipe 20 includes at least one first part 41 and at least one second part 42. The first part 41 extends along a first direction X, and the second part 42 extends along a second direction Y. The first part 41 is connected to the second part 42, and the first direction X and the second direction Y intersect.

[0107] For example, the number of first parts 41 can be one, two, three, four, or more, and the number of second parts 42 can be one, two, three, four, or more. The number of first parts 41 and the number of second parts 42 can be the same or different. The structural shape, size, and material of the first parts 41 and the second parts 42 can be the same or different.

[0108] The first part 41 can be detachably connected to the second part 42, or it can be integrally formed on the second part 42. The first part 41 can be directly connected to the second part 42, or it can be constrained to the second part 42 by other components. As an example, the connection method between the first part 41 and the second part 42 can be, but is not limited to, bolting, welding, riveting, or bonding.

[0109] In some examples, there are multiple first parts 41 and multiple second parts 42, with multiple first parts 41 and multiple second parts 42 connected end to end.

[0110] In some examples, there are multiple first parts 41 and multiple second parts 42, and the multiple first parts 41 and multiple second parts 42 are interconnected to form a network structure.

[0111] The above technical solution, by setting the protective gas delivery pipe 40 located inside the first exhaust gas pipe 20 as a first part 41 and a second part 42 with different extension directions, can increase the extension length and surface area of ​​this part of the protective gas delivery pipe 40, while also increasing the flexibility of setting this part of the protective gas delivery pipe 40, reducing the overall manufacturing difficulty of the battery material manufacturing equipment, and helping to reduce costs.

[0112] In some embodiments, the first direction X and the second direction Y are perpendicular.

[0113] In some embodiments, the protective gas delivery pipe 40 located inside the first exhaust gas discharge pipe 20 further includes at least one third portion 43, which extends along a third direction Z. Each third portion 43 is connected to at least one of the first portion 41 and the second portion 42, and the first direction X, the second direction Y and the third direction Z intersect each other.

[0114] For example, the number of third parts 43 can be one, two, three, four or more, and the number of first parts 41, second parts 42 and third parts 43 can be the same or different. The structural shape, size and material of the first parts 41, second parts 42 and third parts 43 can be the same or different.

[0115] The third part 43 can be connected to either the first part 41 or the second part 42, or the third part 43 can be connected to both the first part 41 and the second part 42.

[0116] In some examples, there are multiple first parts 41, multiple second parts 42, and multiple third parts 43, which are connected alternately from beginning to end. In other words, multiple first parts 41 and multiple second parts 42 are connected alternately from beginning to end, and multiple third parts 43 are connected between the first parts 41 and the second parts 42 respectively.

[0117] In some examples, there are multiple first parts 41, multiple second parts 42 and multiple third parts 43, and these multiple first parts 41, multiple second parts 42 and multiple third parts 43 are interconnected to form a network structure.

[0118] When the third part 43 is connected to the first part 41, the third part 43 can be detachably connected to the first part 41 or integrally formed on the first part 41. The third part 43 can be directly connected to the first part 41 or constrained to the first part 41 by other components. As an example, the connection method between the third part 43 and the first part 41 can be, but is not limited to, bolt connection, welding, riveting, or bonding.

[0119] When the third part 43 is connected to the second part 42, the third part 43 can be detachably connected to the second part 42 or integrally formed on the second part 42. The third part 43 can be directly connected to the second part 42 or constrained to the second part 42 by other components. As an example, the connection method between the third part 43 and the second part 42 can be, but is not limited to, bolting, welding, riveting, or bonding.

[0120] The above technical solution, by further introducing a third part 43, enables the protective gas conveying pipe 40 located inside the first exhaust gas discharge pipe 20 to form a three-dimensional bent structure, which can improve the utilization rate of this part of the protective gas conveying pipe 40 to the internal space of the first exhaust gas discharge pipe 20, thereby further improving the extension length and surface area of ​​this part of the protective gas conveying pipe 40, and thus further improving the heating effect of the protective gas.

[0121] Figure 5 This is a schematic diagram of the layout structure of another battery material manufacturing apparatus provided in some embodiments of this application. Figure 6 for Figure 5 A magnified schematic diagram of the structure at point H.

[0122] Continue to refer to Figures 5 to 6 In some embodiments, the first exhaust gas discharge pipe 20 includes a first main section 21, a second main section 23 and a branch section 22, the branch section 22 being connected between the first main section 21 and the second main section 23, the first main section 21 being connected to the branch section 22 and the sintering device 10, and at least a portion of the protective gas delivery pipe 40 being disposed inside the second main section 23.

[0123] Branch section 22 includes a first pipe 221 and a second pipe 222, both of which are connected between the first main section 21 and the second main section 23 and are arranged in parallel. The first exhaust gas discharge pipe 20 also includes a first control element 24 and a second control element 25. The first control element 24 is disposed in the first pipe 221 and is used to control the on / off state of the first pipe 221, and the second control element 25 is disposed in the second pipe 222 and is used to control the on / off state of the second pipe 222.

[0124] For example, the exhaust gas flows from the first main section 21 through the branch section 22 into the second main section 23, where it heats and protects the gas delivery pipeline 40. The first control element 24 can control the opening and closing of the first pipeline 221 by itself. Specifically, when the first control element 24 is open, the first pipeline 221 is in a closed state; when the first control element 24 is closed, the first pipeline 221 is in a closed state.

[0125] The second control element 25 can control the on / off state of the second pipeline 222 by opening and closing itself. Specifically, when the second control element 25 is open, the second pipeline 222 is in a closed state; when the second control element 25 is closed, the second pipeline 222 is in a closed state.

[0126] The first control element 24 can be directly connected to the first pipe 221, or it can be restricted to the first pipe 221 by other components. The second control element 25 can be directly connected to the second pipe 222, or it can be restricted to the second pipe 222 by other components.

[0127] Optionally, the first control element 24 may be, but is not limited to, a ball valve, gate valve, globe valve, or butterfly valve. The second control element 25 may be, but is not limited to, a ball valve, gate valve, globe valve, or butterfly valve.

[0128] The first control element 24 and the second control element 25 may be the same or different.

[0129] In some examples, the first control element 24 and the second control element 25 may be activated simultaneously, so that a portion of the exhaust gas enters the second section 23 from the first main section 21 through the first pipe 221, and another portion of the exhaust gas enters the second section 23 from the first main section 21 through the second pipe 222. In this example, the exhaust gas flow rate is increased, which improves the efficiency of the exhaust gas heating the protective gas.

[0130] In some examples, the first control element 24 can be turned on while the second control element 25 is turned off, allowing the exhaust gas to enter the second section 23 from the first main section 21 via the first pipe 221. In this example, the second pipe 222 can be used as a backup pipe. In the event of a failure in the first pipe 221, the first control element 24 is turned off and the second control element 25 is turned on, allowing the exhaust gas to enter the second section 23 from the first main section 21 via the second pipe 222, while simultaneously performing maintenance on the first pipe 221. This improves the continuity of exhaust gas heating of the protective gas and reduces the adverse effects of downtime for maintenance due to pipe failures.

[0131] In some examples, the first control element 24 can be closed while the second control element 25 is open, allowing exhaust gas to flow from the first main section 21 through the second pipeline 222 into the second main section 23. In this example, the first pipeline 221 can serve as a backup pipeline. In the event of a failure in the second pipeline 222, the second control element 25 is closed, and the first control element 24 is opened, allowing exhaust gas to flow from the first main section 21 through the first pipeline 221 into the second main section 23, while simultaneously performing maintenance on the second pipeline 222. This improves the continuity of exhaust gas heating of the protective gas and reduces the adverse effects of downtime for maintenance due to pipeline failures.

[0132] The above technical solution introduces a first pipeline 221 and a second pipeline 222 arranged in parallel. One of the first pipeline 221 and the second pipeline 222 can be used as a backup. When the other of the first pipeline 221 and the second pipeline 222 fails and maintenance is required, the exhaust gas can continue to flow through the backup pipeline to heat the protective gas. This can improve the continuity of exhaust gas heating of the protective gas and reduce the adverse effects of downtime maintenance due to pipeline failure.

[0133] In some embodiments, the first conduit 221 includes a first conduit 2211, a second conduit 2212, and a third conduit 2213. The first conduit 2211 is fixed to the first main section 21, the third conduit 2213 is fixed to the second main section 23, the second conduit 2212 is detachably connected between the first conduit 2211 and the third conduit 2213, and a first control member 24 is disposed on the first conduit 2211 and used to control the on / off state of the first conduit 2211.

[0134] The first tube section 2211 can be directly fixedly connected to the first main section 21, or it can be constrained to the first main section 21 by other components. As an example, the connection method between the first tube section 2211 and the first main section 21 can be, but is not limited to, bolt connection, welding, riveting, or bonding.

[0135] The second tube section 2212 can be directly fixedly connected to the first main section 21, or it can be constrained to the first main section 21 by other components. As an example, the connection method between the second tube section 2212 and the first main section 21 can be, but is not limited to, bolt connection, welding, riveting, or bonding.

[0136] In some examples, the second tube 2212 is detachably connected between the first tube 2211 and the third tube 2213 by means of bolts.

[0137] In some examples, the second tube 2212 is detachably connected between the first tube 2211 and the third tube 2213 by a snap-fit ​​connection.

[0138] The first control element 24 is disposed in the first pipe section 2211. In the event of a malfunction in the first pipe section 221, closing the first control element 24 allows the exhaust gas from the first main section 21 to be intercepted in the first pipe section 2211, thus preventing it from entering the second pipe section 2212. This facilitates the disassembly of the second pipe section 2212 for maintenance or cleaning of the entire first pipe section 221.

[0139] The above technical solution, by setting the second pipe section 2212 to be detachably connected between the first pipe section 2211 and the third pipe section 2213, facilitates the repair or cleaning of the first pipe section 221 when a fault occurs, thereby improving the overall maintenance convenience of the first exhaust gas discharge pipe 20.

[0140] In some embodiments, the first conduit 221 includes a first quick connector 2214, and the second conduit 2212 is detachably connected to the first conduit 2211 via the first quick connector 2214.

[0141] A quick coupling is a type of connector that allows for the connection or disconnection of pipes without the need for tools, enabling the quick connection or disconnection of the first pipe section 2211 and the second pipe section 2212.

[0142] The above technical solution, by introducing the first quick connector 2214, can improve the installation and disassembly efficiency between the second tube section 2212 and the first tube section 2211, thereby improving the convenience of assembly or maintenance.

[0143] In some embodiments, the first conduit 221 includes a second quick connector 2215, and the second conduit 2212 is detachably connected to the third conduit 2213 via the second quick connector 2215.

[0144] By introducing the second quick connector 2215, the installation and disassembly efficiency between the second tube section 2212 and the third tube section 2213 can be improved, thereby increasing the convenience of assembly or maintenance.

[0145] In some embodiments, the first exhaust gas discharge pipe 20 further includes a third control element 26, which is disposed on the third pipe section 2213 and used to control the on / off state of the third pipe section 2213.

[0146] For example, the exhaust gas flows from the first main section 21 through the first pipe section 2211, the second pipe section 2212, and the third pipe section 2213 into the second main section 23, where it heats and protects the gas delivery pipe 40. The first control element 24 can control the opening and closing of the first pipe section 2211 by opening and closing itself, and the third control element 26 can control the opening and closing of the third pipe section 2213 by opening and closing itself. Specifically, when both the first control element 24 and the third control element 26 are open, the first pipe section 221 is in a closed state; when both the first control element 24 and the third control element 26 are closed, the first pipe section 221 is in a closed state.

[0147] The third control component 26 can be directly connected to the third tube section 2213, or it can be restricted to the third tube section 2213 by other components.

[0148] Optionally, the third control element 26 may be, but is not limited to, a ball valve, gate valve, globe valve, or butterfly valve. The third control element 26 may be the same as or different from the first control element 24 and the second control element 25.

[0149] The above technical solution, by further introducing a third control component 26, can simultaneously shut down the first control component 24 and the third control component 26 when the second pipe section 2212 is disassembled, repaired, or cleaned. This can reduce the risk of residual exhaust gas in the second main section 23 flowing back out of the third pipe section 2213, thereby reducing environmental pollution and harm to the health of maintenance personnel.

[0150] In some embodiments, a first filter 61 is provided inside the second pipe 222, which is used to filter impurities in the exhaust gas inside the second pipe 2212.

[0151] For example, the impurities in the exhaust gas may be, but are not limited to, particles or dust. The first filter 61 may be, but is not limited to, a fiber filter, an activated carbon filter, or a metal filter.

[0152] In some examples, the first filter 61 is made of a high-temperature and corrosion-resistant material, such as stainless steel or ceramic, so that it can work stably for a long time in high-temperature environments.

[0153] The first filter 61 of the above technical solution can intercept impurities in the exhaust gas in the first exhaust gas discharge pipe 20, reducing the risk of the heating of the protective gas delivery pipe 40 being affected by the accumulation of impurities in the pipe. In addition, the first filter 61 is installed in the second pipe section 2212, and the detachable installation of the second pipe section 2212 facilitates the replacement and maintenance of the first filter 61.

[0154] In some embodiments, the second conduit 222 includes a fourth conduit 2221, a fifth conduit 2222, and a sixth conduit 2223. The fourth conduit 2221 is fixed to the first main section 21, the sixth conduit 2223 is fixed to the second main section 23, the fifth conduit 2222 is detachably connected between the fourth conduit 2221 and the sixth conduit 2223, and the second control member 25 is disposed on the fourth conduit 2221 and used to control the on / off state of the fourth conduit 2221.

[0155] The fourth tube section 2221 can be directly fixedly connected to the first main section 21, or it can be constrained to the first main section 21 by other components. As an example, the connection method between the fourth tube section 2221 and the first main section 21 can be, but is not limited to, bolt connection, welding, riveting or bonding.

[0156] The fifth tube section 2222 can be directly fixedly connected to the first main section 21, or it can be constrained to the first main section 21 by other components. As an example, the connection method between the fifth tube section 2222 and the first main section 21 can be, but is not limited to, bolt connection, welding, riveting or bonding.

[0157] In some examples, the fifth tube 2222 is detachably connected between the fourth tube 2221 and the sixth tube 2223 by means of bolts.

[0158] In some examples, the fifth tube 2222 is detachably connected between the fourth tube 2221 and the sixth tube 2223 by a snap-fit ​​connection.

[0159] The first control element 24 is located in the fourth pipe section 2221. In the event of a malfunction in the second pipe section 222, closing the first control element 24 allows the exhaust gas from the first main section 21 to be intercepted in the fourth pipe section 2221, preventing it from entering the fifth pipe section 2222. This facilitates the disassembly of the fifth pipe section 2222 for maintenance or cleaning of the entire second pipe section 222.

[0160] The above technical solution, by setting the fifth pipe section 2222 to be detachably connected between the fourth pipe section 2221 and the sixth pipe section 2223, facilitates the repair or cleaning of the second pipe section 222 when a fault occurs, thereby improving the overall maintenance convenience of the first exhaust gas discharge pipe 20.

[0161] In some embodiments, the second conduit 222 includes a third quick connector 2224, and the fifth conduit 2222 is detachably connected to the fourth conduit 2221 via the third quick connector 2224. By introducing the third quick connector 2224, the efficiency of installation and removal between the fifth conduit 2222 and the fourth conduit 2221 can be improved, thereby increasing the convenience of assembly or maintenance.

[0162] In some embodiments, the first conduit 221 includes a fourth quick connector 2225, and the fifth conduit 2222 is detachably connected to the sixth conduit 2223 via the fourth quick connector 2225. By introducing the fourth quick connector 2225, the efficiency of installation and removal between the fifth conduit 2222 and the sixth conduit 2223 can be improved, thereby increasing the convenience of assembly or maintenance.

[0163] In some embodiments, the first exhaust gas discharge pipe 20 further includes a fourth control element 27, which is disposed on the sixth pipe section 2223 and used to control the on / off state of the sixth pipe section 2223.

[0164] For example, the exhaust gas flows from the first main section 21, sequentially through the fourth pipe section 2221, the fifth pipe section 2222, and the sixth pipe section 2223 into the second main section 23, where it heats and protects the gas delivery pipeline 40. The second control element 25 can control the opening and closing of the fourth pipe section 2221 by opening and closing itself, and the fourth control element 27 can control the opening and closing of the sixth pipe section 2223 by opening and closing itself. Specifically, when both the second control element 25 and the fourth control element 27 are open, the second pipeline 222 is in a closed state; when both the second control element 25 and the fourth control element 27 are closed, the second pipeline 222 is in a closed state.

[0165] The fourth control component 27 can be directly connected to the sixth tube section 2223, or it can be restricted to the sixth tube section 2223 by other components.

[0166] Optionally, the fourth control element 27 may be, but is not limited to, a ball valve, gate valve, globe valve, or butterfly valve. The fourth control element 27 may be the same as or different from the second control element 25.

[0167] The above technical solution, by further introducing a fourth control component 27, can simultaneously shut down the second control component 25 and the fourth control component 27 when the fifth pipe section 2222 is disassembled, repaired, or cleaned. This reduces the risk of residual exhaust gas in the second main section 23 flowing back out of the sixth pipe section 2223, thereby reducing environmental pollution and harm to the health of maintenance personnel.

[0168] In some embodiments, a second filter 62 is provided inside the fifth pipe, which is used to filter impurities in the exhaust gas inside the fifth pipe section 2222.

[0169] For example, impurities in the exhaust gas may be, but are not limited to, particles or dust. The second filter 62 may be, but is not limited to, a fiber filter, an activated carbon filter, or a metal filter.

[0170] In some examples, the second filter 62 is made of high-temperature and corrosion-resistant materials, such as stainless steel or ceramic, so that it can work stably for a long time in high-temperature environments.

[0171] The second filter 62 of the above-described technical solution can intercept impurities in the exhaust gas in the first exhaust gas discharge pipe 20, reducing the risk of the heating of the protective gas delivery pipe 40 being affected by the accumulation of impurities in the pipe. In addition, the second filter 62 is installed in the fifth pipe section 2222, and the detachable installation of the fifth pipe section 2222 facilitates the replacement and maintenance of the second filter 62.

[0172] In some embodiments, the battery material manufacturing equipment further includes a detection device 50 connected to the first section 21, which is used to detect the fluid pressure inside the first section 21.

[0173] For example, when the first pipeline 221 is working and the second pipeline 222 is in standby mode, the fluid pressure inside the first main section 21 can be monitored in real time by the detection device 50. When the fluid pressure inside the first main section 21 exceeds the set upper limit, the second control component 25 can be opened in time to open the second pipeline 222, and then the first control component 24 can be closed to disconnect the first pipeline 221, and then the first pipeline 221 can be repaired or cleaned.

[0174] When the second pipeline 222 is in operation and the first pipeline 221 is in standby mode, the fluid pressure inside the first main section 21 can be monitored in real time by the detection device 50. When the fluid pressure inside the first main section 21 exceeds the set upper limit, the first control component 24 can be opened in time to open the first pipeline 221, and then the second control component 25 can be closed to disconnect the second pipeline 222, and then the second pipeline 222 can be repaired or cleaned.

[0175] The detection device 50 can be directly and fixedly connected to the first section 21, or it can be limited to the first section 21 by other components. Optionally, the detection device 50 can be, but is not limited to, a pressure gauge or an electronic pressure sensor.

[0176] The above technical solution helps to keep the system operating within the predetermined pressure range. On the other hand, it can switch the first pipeline 221 and the second pipeline 222 in a timely manner according to the fluid pressure inside the first section 21, thereby reducing the risk of production accidents caused by abnormal pressure.

[0177] In some examples, the detection device 50 includes a pressure gauge, which is low in cost and helps reduce the overall cost of battery material manufacturing equipment.

[0178] Figure 7This is a schematic diagram of the layout structure of another battery material manufacturing apparatus provided in some embodiments of this application.

[0179] Continue to refer to Figure 7 In some embodiments, the battery material manufacturing equipment further includes an incineration device 70 and a second exhaust gas discharge pipe 80. The incineration device 70 is located downstream of the sintering device 10, and the second exhaust gas discharge pipe 80 is connected between the sintering device 10 and the incineration device 70. The incineration device 70 is connected between the first exhaust gas discharge pipe 20 and the second exhaust gas discharge pipe 80. The incineration device 70 is used to incinerate the exhaust gas generated by the sintering device 10.

[0180] For example, the exhaust gas generated after calcination of the material in the sintering device 10 may contain some combustible impurities, such as tar, which easily adhere to the inner wall of the pipe. The incineration device 70 further incinerates the exhaust gas generated by the sintering device 10 to incinerate and gasify some combustible impurities in the exhaust gas.

[0181] Specifically, the exhaust gas generated by the sintering device 10 first enters the incineration device 70 through the second exhaust gas discharge pipe 80, and the exhaust gas after being incinerated by the incineration device 70 then enters the first exhaust gas discharge pipe 20 to heat the protective gas delivery pipe 40 located inside the first exhaust gas discharge pipe 20.

[0182] The second exhaust gas discharge pipe 80 can be directly connected between the sintering device 10 and the incineration device 70, or it can be indirectly connected between the sintering device 10 and the incineration device 70 through other devices.

[0183] Optionally, the second exhaust pipe 80 may be, but is not limited to, a square pipe, a circular pipe, or a polygonal pipe.

[0184] Optionally, the second exhaust pipe 80 may be, but is not limited to, made of high-temperature resistant materials such as nickel-based alloys, stainless steel, or ceramics.

[0185] The above technical solution introduces an incineration device 70 to first incinerate the exhaust gas generated by the sintering device 10. The exhaust gas, after incineration by the incineration device 70, then enters the first exhaust gas discharge pipe 20 to heat the protective gas. This process not only incinerates and vaporizes some combustible impurities in the exhaust gas, reducing the risk of impurities adhering to the inner wall of the first exhaust gas discharge pipe 20 and causing blockage, but also extends the service life of the first exhaust gas discharge pipe 20. Furthermore, it further increases the temperature of the exhaust gas entering the first exhaust gas discharge pipe 20, thereby enhancing the heating effect of the exhaust gas on the protective gas.

[0186] Figure 8 This is a schematic diagram of the layout structure of a battery material manufacturing apparatus provided in some embodiments of this application.

[0187] Continue to refer to Figure 8 In some embodiments, the battery material manufacturing equipment further includes an exhaust gas treatment device 90, which is located downstream of the incineration device 70. A first exhaust gas discharge pipe 20 is connected between the incineration device 70 and the exhaust gas treatment device 90. The exhaust gas treatment device 90 is used to purify the exhaust gas in the first exhaust gas discharge pipe 20.

[0188] For example, the main function of the exhaust gas treatment device 90 is to purify the exhaust gas in the first exhaust gas discharge pipe 20 to remove harmful substances and pollutants, so that the gas emitted into the environment meets environmental protection requirements.

[0189] The first exhaust gas discharge pipe 20 can be directly connected between the incineration device 70 and the exhaust gas treatment device 90, or it can be indirectly connected between the incineration device 70 and the exhaust gas treatment device 90 through other devices.

[0190] The above technical solution reduces the risk of environmental pollution by introducing an exhaust gas treatment device 90 to purify the exhaust gas in the first exhaust gas discharge pipe 20.

[0191] In some embodiments, the exhaust gas treatment device 90 is connected between the sintering device 10 and the exhaust gas treatment device 90, and the exhaust gas treatment device 90 is used to purify the exhaust gas in the first exhaust gas discharge pipe 20.

[0192] The first exhaust gas discharge pipe 20 can be directly connected between the sintering apparatus 10 and the exhaust gas treatment device 90, or it can be indirectly connected between the sintering apparatus 10 and the exhaust gas treatment device 90 through other devices. For example, when the battery material manufacturing equipment includes an incineration device 70, the first exhaust gas discharge pipe 20 is connected between the incineration device 70 and the exhaust gas treatment device 90. This can be understood as the first exhaust gas discharge pipe 20 being indirectly connected between the sintering apparatus 10 and the exhaust gas treatment device 90 through the incineration device 70.

[0193] According to some embodiments of this application, this application also provides a battery production system, which includes battery material manufacturing equipment according to any of the above schemes.

[0196] An incineration device 70 is located downstream of the sintering device 10. A second exhaust gas discharge pipe 80 connects the sintering device 10 and the incineration device 70. The incineration device 70 is connected between the first exhaust gas discharge pipe 20 and the second exhaust gas discharge pipe 80. The incineration device 70 is used to incinerate the exhaust gas generated by the sintering device 10. An exhaust gas treatment device 90 is located downstream of the incineration device 70. A first exhaust gas discharge pipe 20 connects the incineration device 70 and the exhaust gas treatment device 90. The exhaust gas treatment device 90 is used to purify the exhaust gas in the first exhaust gas discharge pipe 20.

[0197] The first exhaust gas discharge pipe 20 includes a first main section 21, a second main section 23, and a branch section 22. The branch section 22 connects the first main section 21 and the second main section 23. The first main section 21 connects the branch section 22 and the sintering device 10. At least a portion of the protective gas delivery pipe 40 is disposed inside the second main section 23. The branch section 22 includes a first pipe 221 and a second pipe 222, both of which are connected between the first main section 21 and the second main section 23 and are arranged in parallel. A detection device 50 is connected to the first main section 21 and is used to detect the fluid pressure inside the first main section 21.

[0198] The first exhaust gas discharge pipe 20 also includes a first control element 24, a second control element 25, a third control element 26, and a fourth control element 27. The first pipeline 221 includes a first pipe section 2211, a second pipe section 2212, a third pipe section 2213, a first quick connector 2214, and a second quick connector 2215. The first pipe section 2211 is fixed to the first main section 21, and the third pipe section 2213 is fixed to the second main section 23. The second pipe section 2212 is detachably connected between the first pipe section 2211 and the third pipe section 2213. The first control element 24 is disposed on the first pipe section 2211 and is used to control the on / off state of the first pipe section 2211.
