Description

Technical Field

[0001] This application relates to the field of sintering equipment, and in particular to a roller assembly and a sintering furnace. Background Technology

[0002] Energy conservation and emission reduction are key to the sustainable development of the automotive industry, and electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of this sustainable development. For electric vehicles, battery technology is a crucial factor in their development.

[0003] Battery materials need to be sintered. The sintering furnace mainly consists of three large areas: a heating zone, a high-temperature zone, and a cooling zone. After the battery materials are sintered in the high-temperature zone, they enter the cooling zone and are naturally cooled as the powder sagger moves on the roller conveyor. This cooling method results in a long cooling time, which limits the production line capacity. Utility Model Content

[0004] In view of the above problems, this application provides a roller assembly and a sintering furnace that can improve cooling efficiency.

[0005] In a first aspect, this application provides a roller assembly for a sintering furnace. The roller assembly includes a body, which includes: a first channel having a first receiving cavity; and a second channel located within the first receiving cavity, and the second channel having a second receiving cavity; wherein the first receiving cavity and the second receiving cavity are in communication with each other so that a cooling medium can flow between the first receiving cavity and the second receiving cavity.

[0006] In the technical solution of this application embodiment, the roller assembly body of the sintering furnace includes a first channel and a second channel. The first and second channels can contain cooling media, allowing for relative natural cooling. By incorporating cooling media within the body, the cooling efficiency of the sintering furnace can be accelerated. Furthermore, the second channel is located within the first receiving cavity of the first channel, and the second receiving cavity of the second channel is connected to the first receiving cavity, enabling the cooling media to flow from the first receiving cavity to the second receiving cavity, achieving reciprocating flow of the cooling media within the body, further improving cooling efficiency.

[0007] In some embodiments, the roller assembly further includes a transition section connected to one end of the body. The transition section has a first sub-cavity and a second sub-cavity, the first sub-cavity being in communication with a first receiving cavity, and the second sub-cavity being in communication with the second receiving cavity.

[0008] In the technical solution of this application embodiment, the roller assembly further includes a transition portion connected to one end of the main body. The first sub-cavity of the transition portion is connected to the first receiving cavity, and the second sub-cavity is connected to the second receiving cavity, allowing the cooling medium to flow out through the first sub-cavity, the first receiving cavity, the second receiving cavity, and the second sub-cavity. The inlet and outlet of the cooling medium are located at the same transition portion, which not only allows the cooling medium to reciprocate fully within the main body, but also allows for both input and output of the cooling medium through the same transition portion, simplifying the structure of the roller assembly.

[0009] In some embodiments, the roller assembly further includes an input component that communicates with a first sub-cavity and is rotatably disposed relative to the first sub-cavity along the circumferential direction of the body.

[0010] In the technical solution of this application embodiment, the input component is connected to the first opening, allowing the cooling medium to flow from the input component into the first sub-cavity, and then into the main body. The input component is rotatable relative to the first sub-cavity, and can still deliver the cooling medium to the roller assembly during the rotation of the main body, thereby further improving the cooling efficiency.

[0011] In some embodiments, the input component is provided with an indicator for indicating the flow status of the cooling medium.

[0012] In the technical solution of this application embodiment, the flow state information such as the flow rate and flow volume of the cooling medium can be obtained by using an indicator provided on the input component.

[0013] In some embodiments, the roller assembly further includes an output component in communication with the second sub-cavity, enabling a medium to be input into the first sub-cavity via the input component and to flow out via the output component.

[0014] In the technical solution of this application embodiment, by setting an output component, the cooling medium can flow out after passing through the second opening and the output component.

[0015] In some embodiments, the input component and / or output component are provided with valves.

[0016] In the technical solution of this application embodiment, by setting a valve, it is convenient to shut off the input of the cooling medium in a timely manner, or to allow the input of the cooling medium in a timely manner.

[0017] In some embodiments, the output component is rotatably disposed relative to the adapter.

[0018] In the technical solution of this application embodiment, since the output component is rotatable relative to the adapter, the purpose of the cooling medium being output from the output component while the main body rotates can be achieved.

[0019] In some embodiments, one of the input component and the output component is located on the radial side of the adapter portion and the other is located on the axial side of the adapter portion.

[0020] In the technical solution of this application embodiment, one of the input component and the output component is located on one side in the radial direction and the other is located on one side in the axial direction, which can improve the interference between the positions of the input component and the output component and improve the positional interference between the input component and the output component.

[0021] In some embodiments, the first channel has a first end and a second end opposite to each other along the body axis, and the first end is provided with a seal; the second channel has a third end and a fourth end opposite to each other along the body axis, the third end has an opening and is spaced apart from the seal, and a transition portion is connected to the second end and the fourth end.

[0022] In the technical solution of this application embodiment, a sealing element is provided at the first end of the first channel to improve the sealing effect of the cooling medium. The third end of the second channel and the sealing element are spaced apart, allowing the cooling medium to flow into the second receiving cavity through the gap between the third end and the sealing element. A connecting part is provided at the second end and the fourth end, so that the cooling medium flows into the first receiving cavity through the second end and outputs the cooling medium through the fourth end. The cooling medium can flow from the second end to the first end in the first channel, and then flow from the third end of the second channel to the fourth end and out, achieving the purpose of sufficient flow of the cooling medium within the body, thereby improving the cooling effect.

[0023] In some embodiments, the wall material of the first channel includes stainless steel; and / or, the wall material of the second channel includes stainless steel.

[0024] In the technical solution of this application embodiment, by setting the wall material of the first channel and / or the second channel to stainless steel, not only can the roller assembly have good thermal conductivity, but the manufacturing cost of the roller can also be reduced.

[0025] Secondly, embodiments of this application also provide a sintering furnace, including: a housing and a roller assembly provided in any of the first aspect embodiments above, wherein at least a portion of the roller assembly is located within the housing and is rotatably disposed relative to the housing.

[0026] In this embodiment of the application, the sintering furnace includes a box body and the aforementioned roller assembly. The box body is used to contain the material to be sintered, and the roller assembly is rotatable relative to the box body, so that the roller assembly can not only drive the product to be transported in the box body, but also provide heat exchange to the product and improve cooling efficiency.

[0027] In some embodiments, the roller assembly further includes a transition section, the body extending from inside the housing to outside the housing, the transition section being connected to the body and located outside the housing, the transition section having a first sub-cavity and a second sub-cavity, the first sub-cavity communicating with a first receiving cavity, and the second sub-cavity communicating with the second receiving cavity.

[0028] In the technical solution of this application embodiment, the transfer part for transmitting the cooling medium to the first channel and the second channel is located outside the housing, which facilitates the transmission of the cooling medium to the roller assembly in the normal temperature environment outside the housing.

[0029] In some embodiments, the body has a drive end and a transmission end arranged opposite to each other along its axial direction. Both the drive end and the transmission end are located outside the housing. An adapter is connected to the transmission end, and a drive component is connected to the drive end. The drive component is used to drive the body to rotate.

[0030] In the technical solution of this application embodiment, the driving component and the adapter are located at opposite ends of the main body, so that the driving component can drive the main body to rotate by the driving end, and the adapter can transmit the cooling medium to the main body by the transmission end. The positions of the driving end and the adapter do not interfere with each other.

[0031] The above description is only an overview of the technical solution of this application.

[0049] Currently, judging from market trends, the application of battery devices is becoming increasingly widespread. Battery devices are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely applied in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of battery device applications, market demand is also constantly increasing.

[0050] Materials such as lithium iron phosphate powder for batteries need to undergo sintering processes in a sintering furnace. Products containing battery materials are placed on rollers inside the sintering furnace and fed into the kiln as the rollers rotate, where the sintering process is completed. The sintering furnace consists of three main zones: a heating zone, a high-temperature zone, and a cooling zone. After sintering in the high-temperature zone, the products enter the cooling zone, where the cooling efficiency is relatively low.

[0051] The reason for the above problem is that the cooling method in the cooling zone is natural cooling, which takes a long time and limits the production line capacity.

[0052] To address the aforementioned issues, this application provides a roller assembly 100. The body 110 of the roller assembly 100 includes a first channel 111 and a second channel 113. The first channel 111 has a first receiving cavity 112; the second channel 113 is located within the first receiving cavity 112 and has a second receiving cavity 114. The first receiving cavity 112 and the second receiving cavity 114 are interconnected, allowing a cooling medium to flow between them. The first channel 111 and the second channel 113 can contain the cooling medium, achieving cooling relative to natural cooling. By providing a cooling medium within the body 110, the cooling efficiency of the sintering furnace can be accelerated. Furthermore, the second channel 113 is located within the first receiving cavity 112 of the first channel 111, and the second receiving cavity 114 of the second channel 113 is interconnected with the first receiving cavity 112, allowing the cooling medium to flow from the first receiving cavity 112 to the second receiving cavity 114, achieving reciprocating flow of the cooling medium within the body 110, further improving cooling efficiency.

[0053] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a sintering furnace provided in some embodiments of this application. The sintering furnace can be used to sinter materials such as lithium iron phosphate for batteries. The sintering furnace includes a housing 200 and a roller assembly 100 disposed within the housing 200, the roller assembly 100 being rotatably disposed relative to the housing 200. The roller assembly 100 is used to move the product containing the material to be sintered within the housing 200.

[0054] Optionally, there may be one or more roller assemblies 100. When there are multiple roller assemblies 100, the multiple roller assemblies 100 are arranged side by side with intervals, so that the product can move between the multiple roller assemblies 100.

[0055] Optionally, the sintering furnace may also include heating equipment such as a crucible 400 to heat the product in a high-temperature zone.

[0056] Figure 2 A schematic diagram of the structure of a roller assembly 100 according to an embodiment of this application is shown.

[0057] Firstly, such as Figure 1 and Figure 2 As shown, this application provides a roller assembly 100, which includes a body 110. The body 110 includes a first channel 111 and a second channel 113. The first channel 111 has a first receiving cavity 112. The second channel 113 is located in the first receiving cavity 112 and has a second receiving cavity 114. The first receiving cavity 112 and the second receiving cavity 114 are interconnected so that a cooling medium can flow between the first receiving cavity 112 and the second receiving cavity 114.

[0058] In the technical solution of this application embodiment, the main body 110 of the sintering furnace roller assembly 100 includes a first channel 111 and a second channel 113. The first channel 111 and the second channel 113 can contain a cooling medium, allowing for cooling relative to natural cooling. By providing a cooling medium within the main body 110, the cooling efficiency of the sintering furnace can be accelerated. Furthermore, the second channel 113 is located within the first receiving cavity 112 of the first channel 111, and the second receiving cavity 114 of the second channel 113 is connected to the first receiving cavity 112, allowing the cooling medium to flow from the first receiving cavity 112 to the second receiving cavity 114, achieving reciprocating flow of the cooling medium within the main body 110, which further improves the cooling efficiency.

[0059] Optionally, the body 110 of the roller assembly 100 is used to move the product within the sintering furnace. The product can be wound around the body 110. When the product is wound on the body 110, the cooling medium in the first receiving cavity 112 within the body 110 can provide heat exchange to the product. By directly placing the cooling medium within the body 110, which is in direct contact with the product, the distance between the product and the cooling medium can be reduced, further improving cooling efficiency.

[0060] Optionally, the first channel 111 and the second channel 113 are nested together, with the second channel 113 located within the first channel 111. The cooling medium can flow from the first receiving cavity 112 to the second receiving cavity 114. The nesting of the first channel 111 and the second channel 113 can reduce the overall space occupied by the roller assembly 100 and allow the cooling medium to flow back and forth within the roller assembly 100, thereby fully utilizing the cooling effect of the cooling medium and improving cooling efficiency.

[0061] Optionally, during the use of the roller assembly 100, the cooling medium can flow from the first receiving cavity 112 to the second receiving cavity 114. Before cooling, the cooling medium first passes through the first receiving cavity 112, which is closer to the product, so that the cooling medium can provide a better cooling effect to the product.

[0062] In some embodiments, such as Figures 1 to 3 As shown, the roller assembly 100 also includes a transition section 120 connected to one end of the main body 110. The transition section 120 has a first sub-cavity 121 and a second sub-cavity 122. The first sub-cavity 121 is connected to the first receiving cavity 112, and the second sub-cavity 122 is connected to the second receiving cavity 114.

[0063] Optionally, the adapter 120 may further include a first opening 123 communicating with the first sub-cavity 121 and a second opening 124 communicating with the second sub-cavity 122. Optionally, the first opening 123 may be an input opening and the second opening 124 may be an output opening.

[0064] In the technical solution of this application embodiment, the roller assembly 100 further includes a transition portion 120 connected to one end of the body 110. The first sub-cavity 121 of the transition portion 120 is connected to the first receiving cavity 112, and the second sub-cavity 122 is connected to the second receiving cavity 114, so that the cooling medium can flow into the first sub-cavity 121 through the first opening 123 and flow out through the first receiving cavity 112, the second receiving cavity 114, the second sub-cavity 122, and the second opening 124. The inlet and outlet of the cooling medium are set in the same transition portion 120, which not only allows the cooling medium to fully reciprocate within the body 110, but also allows the cooling medium to be both input and output through the same transition portion 120, thus simplifying the structure of the roller assembly 100.

[0065] Optionally, the adapter 120 can be sleeved outside the body 110, or the adapter 120 can be connected to the end of the body 110, as long as the first receiving cavity 112 and the first sub-cavity 121 are connected, and the second receiving cavity 114 and the second sub-cavity 122 are connected.

[0066] Optionally, the second sub-cavity 122 may be located inside the first sub-cavity 121, and the first sub-cavity 121 and the second sub-cavity 122 are not connected to each other, such that the inner second sub-cavity 122 is connected to the second chamber located inside the body 110, and the first sub-cavity 121 is connected to the outer first chamber.

[0067] In some embodiments, the roller assembly 100 further includes an input component 130, which is in communication with the first sub-cavity 121 and is rotatably disposed relative to the first sub-cavity 121 along the circumferential direction of the body 110.

[0068] Optionally, when the adapter 120 includes the first opening 123 described above, the output component 140 may be connected to the first opening 123 described above.

[0069] In the technical solution of this application embodiment, the input component 130 is connected to the first opening 123, so that the cooling medium can flow from the input component 130 into the first opening 123, and then flow within the body 110. The input component 130 is rotatable relative to the first sub-cavity 121, and can still deliver the cooling medium to the roller assembly 100 during the rotation of the body 110, which can further improve the cooling efficiency.

[0070] The input component 130 can be an input pipe, which is connected to the first opening 123 and rotatably disposed relative to the adapter 120. For example, the adapter 120 is provided with a first connector, which is rotatably disposed relative to the adapter 120, and the input pipe is connected to the first connector, communicating with the first opening 123 through the first connector. During the use of the roller assembly 100, when the main body 110 rotates, causing the product to rotate and the adapter 120 to rotate, the input component 130 can be relatively stopped because it is rotatably disposed relative to the adapter 120, thus improving the problem caused by the input pipe winding around the main body 110.

[0071] In some embodiments, an indicator 131 is provided on the input component 130, which is used to indicate the flow state of the cooling medium.

[0072] In the technical solution of this application embodiment, the flow state information such as the flow rate and flow volume of the cooling medium can be obtained by the indicator 131 provided on the input component 130.

[0073] Optionally, the cooling medium can be water, which has a high specific heat capacity and low cost, providing good cooling effect and low manufacturing cost. Optionally, the indicator 131 can be a water flow indicator 131, which can be used to obtain water flow status information such as water flow velocity and water flow rate.

[0074] In some embodiments, the roller assembly 100 further includes an output component 140, which is in communication with the second sub-cavity 122 so that a medium can be input into the first sub-cavity 121 via the input component 130 and flow out via the output component 140.

[0075] Optionally, when the adapter 120 includes the second opening 124 described above, the output component 140 can be connected to the second opening 124.

[0076] In the technical solution of this application embodiment, by setting the output component 140, the cooling medium can flow out after passing through the second opening 124 and the output component 140.

[0077] Optionally, the output component 140 can be an output pipe, one end of which is connected to the second opening 124, and the other end of which can be connected to a recovery device. Alternatively, the other end of the output component 140 can directly discharge the cooling medium.

[0078] In some embodiments, the input component 130 and / or the output component 140 are provided with valves 150.

[0079] In the technical solution of this application embodiment, by setting valve 150, it is convenient to shut off the input of cooling medium in a timely manner, or to allow the input of cooling medium in a timely manner.

[0080] Optionally, when the cooling medium is cooling water, valve 150 is used to control the flow of water. When valve 150 is open, the cooling medium can flow within input component 130 or output component 140. When valve 150 is closed, the cooling medium is shut off and will not flow within input component 130 or output component 140. Optionally, valve 150 can also be used to control the flow rate of water. By controlling the degree of opening of valve 150, the flow rate of the cooling medium can be controlled.

[0081] In some embodiments, the output component 140 is rotatably disposed relative to the adapter 120.

[0082] In the technical solution of this application embodiment, since the output component 140 is rotatable relative to the adapter 120, the purpose of outputting the cooling medium from the output component 140 can be achieved while the main body 110 rotates.

[0083] Optionally, when the output component 140 is disposed on the side of the adapter 120 in the axial direction X of the main body 110, the output component 140 can be rotatably disposed relative to the adapter 120. When the output component 140 is disposed on the side of the adapter 120 in the circumferential direction of the main body 110, the output component 140 can rotate around the adapter 120 in the circumferential direction of the main body 110, as long as it can rotate while outputting the cooling medium. This embodiment of the application uses the example of the output component 140 being disposed on the side of the adapter 120 in the axial direction X of the main body 110, and the output component 140 being rotatable relative to the adapter 120 for illustration.

[0084] In some embodiments, one of the first opening 123 and the second opening 124 is located on the radial side of the adapter 120 on the body 110, and the other is located on the axial side of the adapter 120 on the body 110.

[0085] In the technical solution of this application embodiment, one of the first opening 123 and the second opening 124 is located on one side in the radial direction and the other is located on one side in the axial direction X, which can improve the interference between the positions of the first opening 123 and the second opening 124 and improve the positional interference between the input component 130 and the output component 140.

[0086] Optionally, the first opening 123 is located on one radial side of the adapter 120, and the second opening 124 is located on one axial side of the adapter 120. The input component 130 is connected to the first opening 123 and can rotate circumferentially around the adapter 120 to input cooling medium radially into the adapter 120. The output component 140 can be connected to the axial end of the adapter 120. When the body 110 rotates the adapter 120, the output component 140 can rotate coaxially with it. Alternatively, the output component 140 can rotate relative to the adapter 120. When the body 110 rotates the adapter 120, the adapter 120 rotates relative to the output component 140, while the output component 140 can remain relatively stationary.

[0087] In some embodiments, the first channel 111 has a first end 111a and a second end 111b that are opposite each other along the axial direction X of the body 110, and the first end 111a is provided with a seal 115; the second channel 113 has a third end 113a and a fourth end 113b that are opposite each other along the axial direction X of the body 110, the third end 113a has an opening and is spaced apart from the seal 115, and the adapter 120 is connected to the second end 111b and the fourth end 113b.

[0088] In the technical solution of this application embodiment, a sealing element 115 is provided at the first end 111a of the first channel 111 to improve the sealing effect of the cooling medium. The third end 113a of the second channel 113 and the sealing element 115 are spaced apart, so that the cooling medium can flow into the second receiving cavity 114 through the gap between the third end 113a and the sealing element 115. The connecting part 120 is provided at the second end 111b and the fourth end 113b, so that the cooling medium is supplied to the first receiving cavity 112 through the second end 111b and the cooling medium is output from the fourth end 113b. The cooling medium can flow from the second end 111b to the first end 111a in the first channel 111, and flow from the third end 113a of the second channel 113 to the fourth end 113b and out, so as to achieve the purpose of sufficient flow of the cooling medium in the body 110, thereby improving the cooling effect.

[0095] In some embodiments, the roller assembly 100 further includes a transition portion 120. The body 110 extends from inside the housing 200 to outside the housing 200. The transition portion 120 is connected to the body 110 and located outside the housing 200.

[0099] In the technical solution of this application embodiment, the driving component 300 and the adapter 120 are located at opposite ends of the main body 110, so that the driving component 300 can drive the main body 110 to rotate by the driving end 100a, and the adapter 120 can transmit the cooling medium to the main body 110 by the transmission end 100b. The positions of the driving end 100a and the adapter 120 do not interfere with each other.

[0100] During use of the roller assembly 100 in this embodiment, the cooling medium can enter the first chamber through the input component 130 and the first sub-cavity 121. The flow rate and on / off state of the cooling medium can be controlled by the valve 150 on the input component 130. The flow information of the cooling medium can be obtained by the indicator 131. The cooling water moves from the second end 111b to the first end 111a in the first chamber, enters the second chamber from the third end 113a of the second channel 113, moves from the third end 113a to the fourth end 113b in the second sub-cavity 122, and is discharged from the output component 140. Since the input component 130 and the output component 140 can be rotatably arranged relative to the transition part 120, the purpose of inputting and outputting the cooling medium while the roller assembly 100 rotates can be achieved.
