TECHNICAL FIELD

[0001] The present application relates to the technical field of industrial furnace, and in particular to an industrial furnace for continuous production and an oxygen-free cracking furnace. BACKGROUND

There are the following problems: first, the material transportation cost is high, and the material is difficult to achieve the ideal state of keeping, such as keeping oxygen-free, which is difficult to achieve and too high in cost. Second, the intermittent production has high energy consumption and high equipment cost, and separate feeding and discharging devices need to be configured for each device, which has a complex structure. Third, the equipment occupies a large area.

In the production process of batteries, tailings that cannot be used will inevitably be produced, and the manufacturer needs to recycle the battery material attached to the aluminum foil, which needs to separate the battery material from the film, that is, to strip and recycle the conductive current collector powder layer (positive active material) attached to the aluminum foil.

[0052] To facilitate the understanding of the continuous production industrial furnace provided by the embodiments of the present application, the application scenarios thereof are first described. The continuous production industrial furnace provided by the embodiments of the present application is used for physical or chemical reaction of materials to process the materials. However, the current industrial furnace usually needs to be completed in each independent device in steps, and the materials have to be transported between devices. There are the following problems: first, the material transportation cost is high, and it is difficult to achieve the ideal holding state of the materials, such as keeping the materials in an oxygen-free state, which is difficult to achieve and has a high cost. Second, the intermittent production has high energy consumption and high equipment cost, and needs to separately configure feeding and discharging devices for each device, which has a complex structure. Therefore, the embodiments of the present application provide a continuous production industrial furnace to overcome the deficiencies of the prior art, realize continuous production, and have the advantages of simple structure, small floor area, and high production efficiency. The following describes the embodiments in combination with specific examples.

[0053] The continuous production industrial furnace provided by the embodiments of the present application is an independent interval tunnel type arrangement continuous production industrial furnace. The continuous production industrial furnace includes a plurality of cabins that are sequentially connected, and the plurality of cabins are independently or in communication to form a closed space. The plurality of cabins at least include a feeding cabin, a material reaction cabin, a transition processing cabin, and a discharging cabin. Specifically, the continuous production industrial furnace further includes a valve arranged between adjacent cabins and used for opening or closing the adjacent cabins. For example, the valve is arranged between the feeding cabin and the material reaction cabin, between the material reaction cabin and the transition cabin, and between the transition cabin and the discharging cabin. When the material is reacted, the valves at both ends of the material reaction cabin are closed. After the reaction is completed, the valves can be opened, and the material can be transported in the adjacent cabin.

[0054] When the material is specifically transported, the continuous production industrial furnace further includes a transportation mechanism. The transportation mechanism includes a plurality of transportation assemblies arranged in each cabin and forming a continuous transportation loading vessel channel. The loading vessel is a device for transporting the material, such as a boat or a trolley carrying the material. The plurality of transportation assemblies are arranged in each cabin and form a connected channel in the plurality of cabins to continuously transport the boat.

[0055] In addition, the continuous production industrial furnace further includes a plurality of baffle assemblies. The plurality of baffle assemblies are alternately arranged with the plurality of transportation assemblies and used for blocking the loading vessel in the corresponding cabin to complete the corresponding processing of the material to be processed. At the same time, the baffle assembly can control the stop of the loading vessel to cooperate with the opening or closing of the valve between the cabins.

[0056] To facilitate the understanding of the continuous production industrial furnace provided by the embodiments of the present application, a specific application of an oxygen-free cracking furnace is taken as an example for description. It should be understood that the continuous production industrial furnace provided by the embodiments of the present application is not limited to the oxygen-free cracking furnace, and can also be other furnace bodies. In the embodiments of the present application, the oxygen-free cracking furnace is taken as an example for description only for the convenience of describing the continuous production industrial furnace.

[0057] In the application of the continuous production industrial furnace in the field of battery, it can be an oxygen-free cracking furnace in particular. Specifically, the oxygen-free cracking furnace is a furnace body applied in the process of processing battery materials by the oxygen-free cracking method in the continuous production industrial furnace. The multiple chambers of the oxygen-free cracking furnace are all filled with protective gas to form oxygen-free chambers. In the embodiment, the protective gas is inert gas. In the specific arrangement, the feeding chamber is communicated with the material reaction chamber, the material reaction chamber is communicated with the transition treatment chamber, and the transition treatment chamber is communicated with the discharging chamber to form a continuous space for processing the material.

[0058] Reference Figure 1 As shown in the drawings, Figure 1 The structure schematic diagram of the oxygen-free cracking furnace provided by the embodiment of the application is shown in the drawings. The oxygen-free cracking furnace provided by the embodiment of the application includes multiple chambers 100. The main bodies of the multiple chambers 100 are all pipes with the same diameter. The multiple chambers 100 are separated by multiple valves 500 arranged between the pipes. Each chamber 100 can be independently sealed to meet the requirements of material reaction or keeping the environmental state in the chamber stable. The valve 500 arranged between the adjacent chambers 100 can be opened or closed to communicate or close the adjacent chambers 100. The multiple chambers 100 form a tunnel type channel to create conditions for continuous pushing of the material. Each chamber 100 can be provided with corresponding accessories according to the process design requirements so that each chamber 100 has corresponding functions. In the embodiment, the vessel loaded with battery materials is a boat. The boat can move in different chambers 100 and stay in each chamber 100 to make the battery materials in different atmospheres. The loaded battery materials complete the corresponding processing procedures. In the specific arrangement, the multiple chambers 100 at least include a feeding chamber 110, a material reaction chamber 120, a transition treatment chamber (which can be a cooling chamber 130) and a discharging chamber 140. The feeding chamber 110 is communicated with the material reaction chamber 120, the material reaction chamber 120 is communicated with the cooling chamber 130, and the cooling chamber 130 is communicated with the discharging chamber 140. Specifically, along the movement direction of the battery materials, the boat passes through the feeding chamber 110, the material reaction chamber 120, the cooling chamber 130 and the discharging chamber 140 in sequence. In the embodiment, the valve 500 is a gate valve. When the gate valve is in the maximum open state, the channel area is equal to the pipe area. The sealing performance of the gate valve meets the use requirements, and the heat insulation performance meets the use requirements. The multiple chambers 100 are all filled with inert gas to form an oxygen-free atmosphere.

[0059] The feeding cabin 110 is a cabin for battery material to enter the oxygen-free cracking furnace, and the boat can enter the material reaction cabin 120 through the feeding cabin 110. The material reaction cabin 120 is a cabin for cracking the battery material, which is the main processing cabin 100 of the entire oxygen-free cracking furnace, and the battery material is cracked in the material reaction cabin 120. After being cracked in the material reaction cabin 120, the boat enters the cooling cabin 130, which is used to cool the cracked battery material to reduce its temperature. The discharging cabin 140 is a cabin for the battery material to be discharged from the oxygen-free cracking furnace, and the battery material can be removed from the oxygen-free cracking furnace through the discharging cabin 140 after being processed.

[0060] When the boat moves in each cabin 100, it is transported by the transportation mechanism. The multiple sets of transportation components of the transportation mechanism are laid in the feeding cabin 110, the material reaction cabin 120, the cooling cabin 130, and the discharging cabin 140, so that the transportation mechanism forms a channel for transporting the boat in the feeding cabin 110, the material reaction cabin 120, the cooling cabin 130, and the discharging cabin 140. The boat can be moved in the feeding cabin 110, the material reaction cabin 120, the cooling cabin 130, and the discharging cabin 140 by the driving of the transportation mechanism. In specific applications, when the material is reacted, the valves 500 at both ends of the material reaction cabin 120 are closed, the valve 500 connected with the feeding cabin 110 is opened when the material enters the material reaction cabin 120, and the valve 500 connected with the cooling cabin 130 is opened when the material enters the cooling cabin 130. The gas replacement device is provided in the feeding cabin 110, the material reaction cabin 120, the cooling cabin 130, and the discharging cabin 140, and the gas atmosphere control device is provided in the gas inlet device. In the embodiment, the diameter of each cabin is 1.2 meters, and the valve 500 used is a gate valve.

[0061] In order to facilitate the boat to stop at the required position, the oxygen-free cracking furnace further comprises multiple baffle assemblies 400, which correspond to the multiple cabins one by one and are used to block the boat in the corresponding cabin 100. For example, when the cabin 100 includes the feeding cabin 110, the material reaction cabin 120, the cooling cabin 130, and the discharging cabin 140, the number of baffle assemblies 400 is three, and the three baffle assemblies 400 are arranged in the feeding cabin 110, the material reaction cabin 120, the cooling cabin 130, and the discharging cabin 140, respectively. In the above technical solution, the battery material is cracked by the cracking of the material reaction cabin 120, and the boat carrying the battery material is facilitated to move in each cabin 100 by arranging the transportation rollers 300 in each cabin 100. In addition, the boat is facilitated to stop in each cabin 100 by arranging the baffle assemblies. The entire oxygen-free cracking furnace has a simple structure.

[0062] The specific structure will be described in detail below with reference to the specific drawings.

[0063] With reference to the foregoing Figure 1 Firstly, the material reaction chamber 120 is described. The material reaction chamber 120 according to the embodiment of the present application is a cracking chamber. The main body of the chamber 100 is a pipe with an inner cylinder diameter of 1.2 meters. The cracking chamber is provided with an ionized water inlet and a tail gas discharge pipe. In use, the material to be treated is aluminum foil scrap with a conductive current collector powder layer (positive active material containing lithium ions) attached thereto. The treatment purpose is to separate the conductive current collector powder layer from the aluminum foil for recycling. The obtained product is a conductive current collector powder containing lithium ions.

[0064] After the aluminum foil scrap with the conductive current collector powder layer attached thereto enters the material reaction chamber 120, ionized water mist is sprayed in the closed material reaction chamber 120. In a near oxygen-free state at normal pressure, the water ions and the lithium ion battery positive electrode scrap are heated to above 400°C and maintained for a certain period of time. The binder is broken down by cracking to separate the conductive current collector powder layer from the aluminum foil, thereby obtaining a conductive current collector powder positive electrode material in powder form.

[0065] In a specific arrangement, the material reaction chamber 120 is provided with valves 500 at both ends to isolate the material reaction chamber 120 from the adjacent feed chamber 110 and cooling chamber 130, thereby preventing the ionized water mist from entering the two adjacent chambers 100 and avoiding the spread of heat from the material reaction chamber 120 to the two chambers, which makes it difficult to maintain the temperature of the material reaction chamber 120, resulting in excessive heat consumption. At the same time, it avoids the temperature of the cooling chamber 130 being too high, which affects the cooling of the material.

[0066] In the embodiment of the present application, the cooling chamber 130 and the discharge chamber 140 are both double-shell structures. Specifically, the cooling chamber 130 has a double-shell structure, and cooling water is filled in the interlayer between the double-shell structure. The discharge chamber 140 also has a double-shell structure, and cooling water is filled in the interlayer between the double-shell structure. The cooling device is also included, which is in communication with the interlayer of the cooling chamber 130 and the interlayer of the discharge chamber 140 through pipes. The cooling device can be a condenser, which is in communication with the interlayers in the cooling chamber 130 and the discharge chamber 140 through pipes to form a circulation loop. The low-temperature water provided by the condenser can be continuously supplemented to the interlayer to cool the cooling chamber 130 and the discharge chamber 140.

[0067] In addition, the cooling chamber 130 is provided with gas inlet and exhaust devices and an oxygen analyzer. The oxygen analyzer monitors the oxygen molecule content of the gas in the chamber in real time. The material can enter the discharge chamber 140 only after being cooled to a certain extent in the cooling chamber 130.

[0068] The discharge chamber 140 is provided with gas inlet and exhaust devices and an oxygen analyzer. The oxygen analyzer monitors the oxygen molecule content of the gas in the chamber in real time. The fully cooled material can be discharged through the openable or closable discharge port and enter the external discharge roller 700.

[0069] The oxygen-free cracking furnace provided by the embodiments of the present application can further comprise a feeding roller 600, wherein the feeding roller 600 is used in cooperation with the feeding cabin 110, and a discharging roller 700 is used in cooperation with the discharging cabin 140. In use, the boat is conveyed by the feeding roller 600 outside the oxygen-free cracking furnace, and is pushed into the feeding cabin 110 by a first trolley cylinder 800 arranged on the feeding roller 600. Similarly, the discharging roller 700 is used to carry the boat removed from the discharging cabin 140 when cooperating with the discharging cabin 140. In a specific arrangement, the discharging cabin 140 is provided with a second trolley cylinder 900, which is used to push the boat from the discharging cabin 140 to the discharging roller 700.

[0070] Referring to Figure 2 and Figure 3 For communication with the outside, the feeding cabin 110 and the discharging cabin 140 are respectively provided with a port matched with the boat. In order to facilitate the control of the communication between the oxygen-free cracking furnace and the outside, the oxygen-free cracking furnace further comprises a door sealing assembly 200, which comprises a door plate 210, a driving connecting rod 220 and a telescopic mechanism 230. The door plate 210 is used to block the port, and the door plate 210 blocks the port when covering the port. When the door plate 210 is removed, the port is opened, and the material can enter and exit through the port. The telescopic mechanism 230 is used as a driving mechanism, which is used to drive the door plate 210 to rotate relative to the port to realize the opening and closing of the port. The driving connecting rod 220 is used as a transmission mechanism, which is used to convert the telescopic movement of the telescopic mechanism 230 into the rotation of the door plate 210. The specific structure of the baffle will be described in detail below in combination with specific drawings.

[0071] Referring to Figure 2 and Figure 3 , Figure 2 A front view of the feeding cabin 110 chamber is shown. When the door plate cooperates with the feeding cabin 110, the door sealing assembly 200 further comprises a first support seat 240 fixed on the feeding cabin 110. The driving connecting rod 220 is hinged to the first support seat 240, one end of the driving connecting rod 220 is hinged to the telescopic end of the telescopic mechanism 230, and the other end is fixedly connected to the door plate 210. The telescopic mechanism 230 is hinged to the feeding cabin 110 or the discharging cabin 140. When the telescopic end of the telescopic mechanism 230 telescopes, it can drive the driving connecting rod 220 to rotate, and in turn drive the door plate 210 to rotate around the first support seat 240. In Figure 2 and Figure 3 The feeding cabin 110 is taken as an example for illustration. The door sealing assembly 200 is also arranged in the same way on the discharging cabin 140. In the embodiments of the present application, only the feeding cabin 110 is taken as an example for illustration.

[0072] Specifically, the driving link 220 comprises a first link 221 and a second link 222, wherein the first link 221 is fixedly connected with the second link 222. When cooperating with the first support seat 240, the connection of the first link 221 and the second link 222 is in the rotating connection of the first support seat 240; and the axis around which the first link 221 and the second link 222 rotate is perpendicular to the length direction of the first link 221 and the second link 222. In addition, when cooperating with the telescopic mechanism 230 and the door plate 210, the first link 221 is hingedly connected with the telescopic end of the telescopic mechanism 230; and the end of the second link 222 away from the first link 221 is fixedly connected with the door plate 210. In combination Figure 1 It can be seen that when the telescopic end of the telescopic mechanism 230 telescopes, the first link 221 and the second link 222 can be driven to rotate around the first support seat 240, thereby driving the door plate 210 to rotate, so as to realize the blocking or opening of the opening.

[0073] Continuing to refer to the structure shown in Figure 2 The first link 221 and the second link 222 are oppositely inclined, and the included angle between them is greater than or equal to 90°, that is, the first link 221 and the second link 222 form a bent link with an included angle greater than 90°, such as 90°, 120°, 150°, etc. Further, the included angle of the first link 221 and the second link 222 can be less than 180°. When the above structure is adopted, the door plate 210 and the telescopic mechanism 230 can be conveniently arranged by using the bent driving link 220. For example, the opening direction of the opening of the opening of the feeding cabin 110 is inclined upward, and the door plate 210 is also arranged in an inclined manner when covering the opening. At this time, the driving link 220 can facilitate the arrangement of the telescopic mechanism 230 on the feeding cabin 110 when the bent link is adopted. As shown in Figure 1 When the telescoping direction of the telescopic mechanism 230 is horizontal, the bent driving link 220 can drive the door plate 210 to move away from the opening or block the opening.

[0074] The length of the first link 221 is less than the length of the second link 222 when the driving link 220 cooperates with the telescopic mechanism 230 and the door plate 210. When this structure is adopted, the driving link 220 can act as a lever, and the arrangement that the length of the first link 221 is less than the length of the second link 222 can enable the telescopic mechanism 230 to drive the door plate 210 to have a larger movement stroke when a smaller telescoping stroke is used. Thus, when the opening is opened, the door plate 210 can avoid the opening, so that the material has a larger space for entering and exiting.

[0075] In addition, when the above structure is adopted, the door plate 210 is not directly connected with the opening, so that the door plate 210 does not occupy the space for entering and exiting the material of the opening when the opening is opened, thereby improving the convenience of entering and exiting the material.

[0076] As can be seen from the above description, the door sealing assembly 200 provided by the embodiment of the present application drives the opening and closing of the door plate 210 by adopting the lever principle, and by adopting the cooperation of two different connecting rods, the telescopic mechanism 230 can drive the door plate 210 to obtain a larger stroke with a smaller stroke, so that the opening of the door plate 210 does not affect the passability of the materials.

[0077] With reference to the foregoing Figure 2 and Figure 3 In an implementable scheme, the number of the second connecting rods 222 is two; the two second connecting rods 222 are arranged on the two sides of the telescopic mechanism 230. The driving connecting rod 220 further comprises a cross rod 223 rotationally connected with the first support seat 240, the two second connecting rods 222 are fixedly connected with the cross rod 223 respectively, and the first connecting rod 221 is fixedly connected with the cross rod 223. That is, the first connecting rod 221 and the second connecting rod 222 are fixedly connected through the cross rod 223. When cooperating with the first support seat 240, the cross rod 223 is rotationally connected with the first support seat 240, so that the first connecting rod 221 and the second connecting rod 222 can rotate around the first support seat 240. When the two second connecting rods 222 are fixedly connected with the door plate 210, the stress of the door plate 210 can be improved, and the stress balance of the door plate 210 can be ensured. In addition, the force applied to the door plate 210 by the telescopic mechanism 230 is improved, so that the stability of the door plate 210 when opening and the force of the door plate 210 when sealing the opening can be ensured.

[0078] Specifically, the two second connecting rods 222 are symmetrically arranged on the opposite sides of the telescopic mechanism 230. That is, the two second connecting rods 222 are symmetrically arranged on the two sides of the first connecting rod 221. When the above structure is adopted, the force applied by the telescopic mechanism 230 through the first connecting rod 221 can be synchronously transmitted to the two second connecting rods 222, so that the stress balance of the door plate 210 can be ensured.

[0079] With reference to the foregoing Figure 2 When the first support seat 240 is specifically arranged, the number of the first support seat 240 is two, and the two first support seats 240 are arranged on the two sides of the cross rod 223 and are rotationally connected with the cross rod 223 respectively. By rotationally connecting the two first support seats 240 with the two ends of the cross beam respectively, the stability of the cross rod 223 when rotating can be improved. In addition, the two second connecting rods 222 are located between the two first support seats 240, so that the stability of the driving connecting rod 220 when rotating can be further improved.

[0080] With reference to the foregoing Figure 2 and Figure 3In the specific setting of the first support seat 240, the first support seat 240 is arranged on the end face of the inlet cabin 110 or the outlet cabin 140 where the opening is located, and the first support seat 240 is arranged in a direction away from the opening. In the above-mentioned arrangement, the first support seat 240 arranged in the above-mentioned manner avoids affecting the space for the material to enter or exit the opening. In addition, the arrangement of the first support seat 240 at this position also facilitates the arrangement of the driving connecting rod 220.

[0081] As an optional solution, when the driving connecting rod 220 is connected to the door plate 210, the length direction of the second connecting rod 222 is parallel to the plane of the door plate 210 away from the opening. In the above-mentioned arrangement, the space occupied by the second connecting rod 222 can be reduced, and the space occupied by the entire device can be reduced.

[0082] In another implementable solution, the position where the second connecting rod 222 is hinged to the door plate 210 is close to the center of gravity of the door plate 210. In this state, when the door plate 210 rotates, the center of gravity of the door plate 210 can be regarded as being located on the line connecting the two positions where the second connecting rod 222 is fixedly connected to the door plate 210, so that the stress on the door plate 210 can be improved.

[0083] In the above-mentioned technical solution, the telescopic mechanism 230 can adopt different telescopic mechanisms. For example, the telescopic mechanism 230 can be a telescopic pneumatic cylinder, a telescopic hydraulic cylinder, or a linear motor. In the specific setting, different driving mechanisms can be selected according to the needs.

[0084] Continuing to refer to Figure 1 After the boat enters the oxygen-free cracking furnace, the boat is transported by the conveying roller. The conveying mechanism includes a plurality of conveying assemblies arranged in each cabin 100 and constituting a continuous conveying path for the loading vessel. In an example, the conveying assembly is a conveying roller 300, and the number of conveying rollers 300 is multiple, and the multiple conveying rollers 300 are arranged along the length direction of the cabin 100. Each conveying roller 300 is arranged on the cabin 100 of the oxygen-free cracking furnace, and part of the conveying roller 300 is located in the cabin 100 and part of the conveying roller 300 is exposed outside the cabin 100. Among them, the part of the conveying roller 300 located in the cabin 100 cooperates with the boat to drive the boat to move by rotating the conveying roller 300. The part of the conveying roller 300 located outside the cabin 100 serves as a power connection part to drive the conveying roller 300 to move through the chain wheel 320 or other transmission mechanisms. In this way, the driving mechanism for driving the conveying roller 300 to rotate can be located outside the cabin 100, without occupying the space in the cabin 100. The cooperation structure of the conveying roller 300 and the cabin 100 will be described in detail below with reference to the accompanying drawings.

[0085] Referring to Figure 4 and Figure 5 , Figure 4 Fig. 2 shows a schematic view of the conveying roller 300 arranged in the cabin 100, Figure 5A partial enlarged view of the transport roller 300 cooperating with the chamber 100 is shown. The transport roller 300 provided by the embodiments of the present application mainly comprises a sleeve 330, a roller shaft 310 and a bearing seat 340. The roller shaft 310 serves as the main structure of the transport roller 300, which is a circular shaft as a whole. When cooperating with the chamber 100, the roller shaft 310 is arranged in the side wall of the chamber 100 and partially located in the chamber 100 and partially located outside the chamber 100. The part of the roller shaft 310 located in the chamber 100 is used to cooperate with the boat. The sleeve 330 and the bearing seat 340 serve as the support structure to rotatably connect the roller shaft 310 and the side wall of the chamber 100.

[0086] Specifically, the sleeve 330 is arranged in the side wall of the chamber 100 and sealingly connected with the side wall. For example, the sleeve 330 can be sealingly connected with the side wall of the chamber 100 by welding or by sealing glue. When the sleeve cooperates with the side wall of the chamber 100, the roller shaft 310 is arranged in the sleeve 330. Specifically, the sleeve 330 has a hollow cavity, and the roller shaft 310 is arranged in the cavity of the sleeve 330. Moreover, one end of the roller shaft 310 is exposed outside the bearing seat 340, and the end of the roller shaft 310 exposed outside the bearing seat 340 is fixedly connected with a sprocket 320. The driving mechanism can drive the sprocket 320 to move through the transmission belt, so as to drive the roller shaft 310 to rotate.

[0087] As an optional solution, the roller shaft 310 is a stepped shaft, and the diameter of the part of the roller shaft 310 located in the chamber 100 and exposed outside the sleeve 330 is smaller than the inner diameter of the sleeve 330. In this way, the roller shaft 310 is directly inserted from the end of the sleeve 330 exposed outside the chamber 100, which facilitates the assembly and replacement of the roller shaft 310.

[0088] As an implementable solution, the sleeve 330 partially passes through the side wall of the chamber 100 and is exposed in the chamber 100, and the other part is exposed outside the chamber 100, so that the sleeve 330 has a relatively long length to cooperate with the roller shaft 310.

[0089] When the bearing seat 340 is assembled, the bearing seat 340 is fixedly and sealingly connected with the sleeve 330. Specifically, the bearing seat 340 is nested in the sleeve 330 and fixedly connected with the sleeve 330. The bearing 390 is fixedly arranged in the bearing seat 340, and the roller shaft 310 is rotatably connected with the sleeve 330 through the bearing 390, so as to reduce the friction of the roller shaft 310 when rotating through the bearing 390.

[0090] When the bearing seat 340 is fixedly connected to the sleeve 330, a first connecting flange 331 may be provided on the sleeve 330, and a second connecting flange 341 may be provided on the bearing seat 340. The first connecting flange 331 and the second connecting flange 341 are fixedly connected via threaded connectors (such as bolts or bolt assemblies) to achieve a fixed connection between the bearing seat 340 and the sleeve 330. It should be understood that when the bearing seat 340 and the sleeve 330 are fixedly connected, the bearing seat 340 is partially inserted into the hollow cavity of the sleeve 330 and may have an interference fit with the sleeve 330 to ensure stability between the sleeve 330 and the bearing seat 340.

[0091] Of course, in addition to the above-mentioned example of fixing the bearing seat 340 and the sleeve 330 by means of a flange, other methods can also be used to fix the bearing seat 340 and the sleeve 330. For example, the bearing seat 340 and the sleeve 330 can be fixedly connected by welding or bonding, which are not described one by one in the embodiments of the present application.

[0092] When the bearing seat 340 and sleeve 330 are sealed together, a first sealing gasket 380 is installed on the second connecting flange 341. The first and second connecting flanges 331 and 341 are sealed together via the first sealing gasket. The seal between the first and second connecting flanges 331 and 341 thus seals the bearing seat 340 and sleeve 330, preventing the gap between the bearing seat 340 and sleeve 330 from affecting the sealing performance of the oxygen-free cracking furnace. The first sealing gasket can be a rubber or resin seal, or alternatively, other materials.

[0093] When the bearing seat 340 is mated with the roller shaft 310, a heat-insulating material layer 360 is provided in the bearing seat 340. The heat-insulating material layer 360 axially wraps the roller shaft 310 to fill the gap between the roller shaft 310 and the bearing seat 340 through the heat-insulating material layer 360, and isolates the heat exchange between the inside and outside of the cabin 100 through the heat-insulating material layer 360. When the heat-insulating material layer 360 is specifically provided, the bearing seat 340 has a stepped hole; wherein the hole with a larger diameter is used to fix the outer ring of the bearing 390; and the hole with a smaller diameter is provided with a groove for accommodating the heat-insulating material layer 360. Figure 5 As shown in FIG, the larger diameter hole is located on the side where the second connecting flange 341 is located and outside the sleeve 330, ensuring that the bearing 390 is not affected by the sleeve 330 when mating with the bearing seat 340. Furthermore, the smaller diameter hole is located within the sleeve 330, and a groove is defined in and surrounds the inner wall of the smaller diameter hole. The groove extends along the length of the bearing seat 340, ensuring that the thermal insulation material layer 360, when filled in the groove, has a certain thickness along the length of the bearing seat 340, thereby ensuring effective thermal insulation.

[0094] The heat insulation layer 360 can be made of different heat insulation materials. For example, the heat insulation layer can be made of porous material, which uses the internal pores to insulate heat, such as foamed material and fibrous material. Alternatively, the heat insulation layer 360 can be made of rock wool board, expanded polystyrene board, extruded polystyrene board, or other heat insulation materials.

[0095] In an alternative embodiment, the bearing seat 340 is provided with a second sealing gasket 370, and the bearing seat 340 is sealingly connected to the roller shaft 310 through the second sealing gasket 370. In combination with the first sealing gasket 360, the roller shaft 310 is sealingly connected to the bearing seat 340. Figure 4 and Figure 5 As can be seen, the sleeve 330 is sealingly connected to the side wall of the cabin 100, the bearing seat 340 is sealingly connected to the sleeve 330 (through the first sealing gasket), and the roller shaft 310 is sealingly connected to the bearing seat 340 (through the second sealing gasket), so that the roller shaft 310 is also sealingly connected to the side wall of the cabin 100. In addition, the heat insulation layer 360 is filled between the roller shaft 310 and the bearing seat 340, which improves the heat exchange between the inside of the cabin 100 and the outside of the cabin 100, and improves the performance of the oxygen-free cracking furnace.

[0096] As an alternative embodiment, the second sealing gasket 370 is made of self-lubricating material. For example, a self-lubricating silica gel sealing ring can be used. The self-lubricating silica gel sealing ring is made of silica gel material with the addition of lubricating oil special materials. After the rubber product is vulcanized and formed, the surface of the silica gel sealing ring is smooth and lubricated, which can reduce friction. For example, polytetrafluoroethylene (PTFE) has excellent properties such as chemical stability, high and low temperature resistance, low friction coefficient, and self-lubricating property. Therefore, polytetrafluoroethylene material can be selected, and other self-lubricating materials such as nitrile rubber and silica gel material can also be selected.

[0097] In an alternative embodiment, the heat insulation layer 360 is away from the sprocket 320 relative to the second sealing gasket 370 along the length direction of the roller shaft 310. In this way, the second sealing gasket 370 isolates the heat insulation layer 360 from the external environment, so as to avoid the influence of external impurities on the heat insulation performance of the heat insulation layer 360.

[0098] As an alternative embodiment, the transport roller 300 further comprises a thrust cover 350, which is fixedly connected to the bearing seat 340 and used to cooperate with the bearing seat 340 to fix the bearing 390. Specifically, the thrust cover 350 covers one end of the bearing seat 340 exposed to the sleeve 330 and is fixedly connected to the bearing seat 340 through bolts or screws. The bearing 390 is fixed by cooperating the thrust cover 350 with the stepped hole in the bearing seat 340, so as to reduce the influence of the shaking of the bearing 390 on the rotation of the roller shaft 310.

[0099] It can be seen from the above description that the transport roller 300 provided by the embodiment of the present application can isolate the heat in the cabin 100 by arranging the heat insulation material layer 360 in the bearing seat 340, so as to avoid the decrease of the sealing performance of the whole oxygen-free cracking furnace due to the penetration of the roller shaft 310, and improve the use effect of the oxygen-free cracking furnace.

[0100] When the material boat is transported, the material boat is transported in each cabin by the transport mechanism. In addition, a valve is arranged in different cabins to isolate each cabin. The valve is arranged between adjacent cabins and is used to open or close the adjacent cabins. For example, the feed cabin 110 and the material reaction cabin 120 are taken as examples. When the material does not enter the feed cabin 110, the valve is closed, and the feed cabin 110 is isolated from the material reaction cabin 120. When the material boat is transported to the joint of the feed cabin 110 and the material reaction cabin 120 by the transport mechanism, the valve is opened, and the material boat can smoothly enter the material reaction cabin 120 from the feed cabin 110.

[0101] In order to facilitate the material boat to stop in the material reaction cabin 120, the passage or stop of the material boat is controlled by the baffle assembly in the embodiment of the present application.

[0102] Reference Figure 6 , Figure 6 A side view of the oxygen-free cracking furnace applied in the cabin is shown. When the material boat is transported in the oxygen-free cracking furnace, the material boat is transported by the transport roller 300 arranged in the cabin 100. The number of the transport roller 300 is multiple, and the multiple transport rollers 300 are arranged along the length direction of the cabin 100 at intervals to form a channel for transporting the material boat. When the material boat needs to stop, the material boat is blocked by the baffle assembly 400 provided by the embodiment of the present application. Specifically, the baffle assembly 400 is arranged in the cabin 100 and located between two adjacent transport rollers 300. When the material boat needs to be blocked, the baffle assembly 400 is exposed outside the support surface of the transport roller 300 supporting the material boat, so that the baffle assembly 400 can press against the material boat to block the material boat from continuing to move forward. The specific structure of the baffle assembly 400 is described in detail below.

[0103] Reference Figure 7 and Figure 8 , Figure 7 A front view of the baffle assembly 400 applied in the cabin 100 is shown, Figure 8A front structure schematic diagram of the baffle assembly 400 is shown. The baffle assembly 400 provided by the embodiments of the present application mainly comprises a second support seat 410, a baffle 420, a first connecting rod 430, a second connecting rod 440 and a telescopic driving mechanism 450. The second support seat 410 is fixed in the cabin 100, which serves as a support structure of the whole baffle assembly 400 to support the baffle 420. The baffle 420 serves as a functional part of the baffle assembly 400, which is used to cooperate with the boat to achieve the blocking and release of the boat. The first connecting rod 430, the second connecting rod 440 and the telescopic driving mechanism 450 are used to constitute a connecting rod driving mechanism to achieve the blocking and release of the boat by driving the baffle 420 to rotate.

[0104] Specifically, when the second support seat 410 is fixed, it is fixed on the side wall in the cabin 100, as shown in Figure 7 When the second support seat 410 is fixed in the cabin 100, it is located below the transport roller 300, and the height thereof is lower than the support surface of the transport roller 300 supporting the boat, so as to ensure that the arrangement of the second support seat 410 does not affect the same line of the boat. When fixed, the second support seat 410 can be fixed on the side wall of the cabin 100 by bolts or screws. Of course, it can also be fixed in the cabin 100 by bonding or welding.

[0105] When supporting the baffle 420, the baffle 420 is rotationally connected with the second support seat 410. Specifically, a first rotation shaft 460 is provided on the second support seat 410, and the baffle 420 is rotationally connected with the second support seat 410 through the first rotation shaft 460. In a specific embodiment, the axis of the first rotation shaft 460 is perpendicular to the axis of the transport roller 300, so that the path passed by the baffle 420 when rotating is perpendicular to the axis of the transport roller 300, thereby ensuring that the space occupied by the baffle 420 during rotation is small.

[0106] Referring to Figure 8 and Figure 4 In an optional embodiment, the second support seat 410 can comprise oppositely arranged first and second support plates 411 and 412; the baffle 420 is located between the first and second support plates 411 and 412, and the first rotation shaft 460 is rotationally connected with the first and second support plates 411 and 412, respectively. The first and second support plates 411 and 412 can support the opposite ends of the rotation shaft, thereby ensuring the stability of the first rotation shaft 460 during rotation, and the baffle 420 located between the two support plates also enhances the stability of the baffle 420 during rotation.

[0107] When the baffle 420 is rotationally connected to the second support base 410 through the first rotation shaft 460, the first rotation shaft 460 can be rotationally connected to the second support base 410, and the first rotation shaft 460 is fixedly connected to the baffle 420, so as to realize the rotation of the baffle 420 relative to the second support base 410. It should be understood that when the first rotation shaft 460 is rotationally connected to the second support base 410, the first rotation shaft 460 can be rotationally connected to the second support base 410 through a bearing.

[0108] In the embodiment of the present application, the baffle 420 is a long strip structure, and the length direction of the baffle 420 is perpendicular to the axis direction of the first rotation shaft 460. The baffle 420 has two end portions, one of which is a blocking end used to abut against the boat to limit the boat. Specifically, when the baffle 420 is used, the baffle 420 has two different states. For example, when the baffle 420 is rotated to a first position, the blocking end is exposed on one side of the transport roller 300 supporting the boat. In this state, when the boat travels to the baffle assembly 400, the blocking end can be pressed against the boat to limit the boat. When the baffle 420 is rotated to a second position, the blocking end is hidden between the transport rollers 300. At this time, the height of the blocking end is lower than the support surface of the transport roller 300 supporting the boat, and the boat can pass through without obstacles when traveling to the baffle assembly 400.

[0109] When the baffle 420 is driven, it is driven through the first connecting rod 430, the second connecting rod 440, and the telescopic driving mechanism 450. In a specific connection, the first connecting rod 430 is fixedly connected to the baffle 420, the second connecting rod 440 is rotationally connected to the first connecting rod 430, and the second connecting rod 440 is rotationally connected to the telescopic driving mechanism 450. As can be seen from the structure shown in Figure 8 When the first connecting rod 430 is fixedly connected to the baffle 420, the blocking end and the first connecting rod 430 are located on both sides of the first rotation shaft 460. The two ends of the second connecting rod 440 are connected to the first connecting rod 430 and the telescopic driving mechanism 450, respectively. Specifically, one end of the second connecting rod 440 is rotationally connected to the first connecting rod 430 through the second rotation shaft 470, and the other end of the second connecting rod 440 is rotationally connected to the telescopic driving mechanism 450 through the third rotation shaft 490. It should be understood that the axes of the first rotation shaft 460, the second rotation shaft 470, and the third rotation shaft 490 are parallel.

[0110] When the baffle 420 is rotated, the telescopic driving mechanism 450 can pull the second connecting rod 440 through its own telescopic extension, the second connecting rod 440 pulls the first connecting rod 430, and finally drives the baffle 420 to rotate around the first rotation shaft 460. For example, Figure 8In the state of the baffle assembly 400 shown in the figure, when the telescopic driving mechanism 450 is retracted, the second connecting rod 440 can be pulled to move to the right, and the baffle 420 is pulled to rotate counterclockwise by the first connecting rod 430, the blocking end of the baffle 420 is lowered, and the baffle 420 is hidden between the transport rollers 300, so as to remove the blocking of the boat. Of course, when it is necessary to block the boat, the telescopic driving mechanism 450 can be extended outward to push the second connecting rod 440 to move to the left, and the baffle 420 is rotated clockwise to restore to the position shown in the figure. Figure 8 The position of the baffle 420 in the figure.

[0111] In an alternative embodiment, when the baffle 420 is fixedly connected with the first rotating shaft 460, the first connecting rod 430 can be fixedly connected with the baffle 420 through the first rotating shaft 460. Specifically, the baffle 420 is fixed on the first rotating shaft 460, and the first connecting rod 430 is also fixedly connected with the first rotating shaft 460, so as to realize the fixed connection of the baffle 420 and the first connecting rod 430.

[0112] In an embodiment, when one end of the first rotating shaft 460 is exposed at the end of the second support plate 412, the first connecting rod 430 is fixedly connected with the first rotating shaft 460 exposed at the end of the first support plate 411. In order to arrange the first connecting rod 430 outside the two second support seats 410, and the first connecting rod 430 and the baffle 420 can be isolated by the first support plate 411.

[0113] When the first connecting rod 430 is connected with the second connecting rod 440, in order to improve the stability of the second connecting rod 440 when rotating, the first connecting rod 430 can include two sub-connecting rods arranged oppositely, both of which are fixedly connected with the first rotating shaft 460; one end of the second connecting rod 440 is located between the two sub-connecting rods and is rotatably connected with the two sub-connecting rods through the second rotating shaft 470. Thus, the end of the second connecting rod 440 is clamped in the middle by the two sub-connecting rods, improving the stability of the connection between the second connecting rod 440 and the first connecting rod 430.

[0114] The telescopic driving mechanism 450 can be a telescopic pneumatic cylinder or a telescopic hydraulic cylinder, so as to realize driving through the telescopic piston rod of the telescopic pneumatic cylinder or the telescopic hydraulic cylinder. Specifically, when the second connecting rod 440 is connected with the telescopic driving mechanism 450, the piston rod of the telescopic pneumatic cylinder or the telescopic hydraulic cylinder is rotatably connected with the second connecting rod 440. For example, the end of the piston rod is provided with a connecting head 480; the connecting head 480 is a U-shaped structure; the end of the second connecting rod 440 is inserted into the U-shaped structure and is rotatably connected with the connecting head 480 through the third rotating shaft 490. Thus, the end of the second connecting rod 440 is clamped by the U-shaped structure, enhancing the stability of the connection between the second connecting rod 440 and the telescopic driving mechanism 450.

[0115] In the specific setting of the telescopic drive mechanism 450, the telescopic drive mechanism 450 is fixed in the cabin 100, and the axis of the piston rod is parallel to the axis of the transport roller 300. So that the overall length of the telescopic drive mechanism 450 is parallel to the length direction of the transport roller 300. When the baffle assembly 400 is installed, it is convenient to place the entire mechanism in the gap between two adjacent transport rollers 300.

[0116] In an alternative, the length direction of the first connecting rod 430 is the same as the length direction of the baffle 420. When this connection is adopted, the forces on both sides of the first rotating shaft 460 can be relatively balanced.

[0117] As can be seen from the above description, the baffle assembly 400 provided by the embodiments of the present application controls the rotation of the baffle 420 through the cooperation of the baffle 420, the connecting rod and the telescopic drive mechanism 450, so as to achieve the blocking or allowing of the boat in the cabin 100. In addition, the baffle assembly 400 has simple structure, high reliability and small space occupation. In addition, when the baffle 420 blocks the boat, the force of the baffle 420 blocking the boat will not be transmitted to the telescopic drive mechanism 450, and the boat can be blocked by the structural strength of the baffle 420, the second support seat 410 and the first rotating shaft 460. The blocking force will not be transmitted to the telescopic drive mechanism 450, thereby reducing the influence on the telescopic drive mechanism 450.

[0118] In specific use, when the boat loaded with leftover materials passes through the feed roller 600 to the opening (feed port) of the feed cabin 110, at this time the door plate 210 of the feed port is opened by the telescopic mechanism 230, the boat is pushed into the feed cabin 110, and the transport mechanism moves the boat to a suitable position. When the boat is full, the door plate of the feed cabin 110 is closed, and the gas replacement is maintained to keep each cabin in an oxygen-free state. The valve between the material reaction cabin 120 and the feed cabin 110 is opened, the boat enters the material reaction cabin 120, and the valve is closed. The material reaction cabin 120 is heated to the required temperature, and the water ion generation system sprays ionized water into the material reaction cabin 120. After a period of time of cracking, the valve between the cracking cabin and the cooling cabin 130 is opened, and the boat enters the cooling cabin 130 through the cracking transport mechanism. When all the boats in the cracking cabin enter the cooling cabin 130, the valve is closed again. The cooling cabin 130 is a water-cooled double-layer jacketed cabin, and the circulating cooling water continuously reduces the temperature in the cabin. The material entering the cooling cabin 130 is thus continuously cooled to the required temperature. The boat after the cooling cabin 130 enters the discharge cabin 140, and the door plate of the discharge port is opened. The boat sequentially enters the feed cabin 110, the material reaction cabin 120, the cooling cabin 130 and the discharge cabin 140, and is kept in an oxygen-free state through gas replacement.

[0119] It can be seen from the above description that the oxygen-free cracking furnace provided by the embodiment of the application cracks the recovered battery material by using the material reaction cabin through cracking, in addition, the transport mechanism is arranged in each cabin to facilitate the movement of the boat carrying the battery material in each cabin. Furthermore, the stop of the boat in each cabin is facilitated by the baffle assembly. The entire oxygen-free cracking furnace has a simple structure.

[0120] In the embodiment, since the width of the gate valve is only 0.2 meters, the transport rollers 300 arranged in the two adjacent cabins 100 do not hinder the opening and closing of the valve 500, and the adjacent interval distance between the transport rollers 300 is minimized. When the boat travels through the valve 500, it can reach the transport rollers 300 of the next cabin 100 while being supported by at least three transport rollers 300 in the previous cabin, thereby smoothly completing the pushing of the boat between the cabins 100.

[0121] In addition, in the above technical solution, the continuous production industrial furnace includes a plurality of cabins 100 which are independent and arranged in series, each cabin 100 can be independently closed and has a different furnace atmosphere, two or more cabins 100 can be connected to each other, and the transport mechanism is arranged to pass through each cabin 100, so that the material can be continuously pushed between the cabins 100. The material is always in the boat but is in different atmospheres by staying in different cabins 100 to complete each stage of material processing.

[0122] Specifically, the continuous production industrial furnace provided by the application can meet the processing needs of different stages of the material to be processed. For example, when the material needs to be heated and reacted, it is allowed to stay in a cabin with specific corresponding reaction conditions, and the cabin is closed to create corresponding process conditions, such as inputting inert gas into the cabin to form an oxygen-free atmosphere, or vacuumizing the cabin to form a vacuum atmosphere. After the reaction is completed, the material can be seamlessly pushed into the adjacent cabin to enter the subsequent processing stage, and the process conditions of the cabin are set according to the subsequent processing requirements, such as cooling. Each cabin works independently, and the boat completes the stay and pushing of the material, and different batches of materials are continuously processed, so that continuous production is realized.

[0123] The technical effects are embodied in:

[0124] 1. Continuous production is realized. The material to be processed is allowed to stay in each independent interval arranged in a tunnel and complete corresponding reactions or post-processing by the transport mechanism, the baffle assembly, and the valve. The process flow is optimized by reasonable setting of the processing links, and each independent space can be individually set to a predetermined internal atmosphere, thereby realizing batch-by-batch continuous processing of multiple processes, and greatly reducing the time and energy consumption required for material processing.

[0125] 2. The materials to be processed do not need to be transferred between the various equipment. Instead, they are pushed to the connected compartments by a transportation mechanism, avoiding the need for insulation, cooling, heating and other measures required for the transfer of materials in different processes, reducing production costs, and keeping the materials to be processed in an ideal state at a lower cost. Compared with intermittent equipment of the same capacity, the production efficiency can be increased by ten or even dozens of times.

[0126] 3. Equipment costs are significantly reduced and the floor space required is small. By achieving continuous production and eliminating material transfer, separate feeding and discharging devices are no longer required between processing equipment, saving on materials and consumables required for transfer. The overall structure of the equipment is simple, greatly improving space utilization. Compared with batch production equipment, the floor space required is only one-fifth of that of batch production equipment, and the equipment cost is only one-third, showing good technical and economic feasibility.

[0127] In addition, transport rollers are installed in each compartment to facilitate the movement and pushing of the material boat within each compartment. Furthermore, baffle assemblies are provided to facilitate the control of the material boat's stopping within each compartment. The entire industrial furnace has a simple structure.
