Description

Technical Field

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

[0002] Material processing usually involves heating reaction and post-processing, such as the recovery of battery material tailings, the reduction and purification of metal-containing materials, and the drying of powder materials. The required reaction conditions are different, and usually need to be completed step by step in each independent device, and the materials have to be transported between the devices. There are the following problems: First, the cost of material transportation is high, and it is difficult to maintain the material in an ideal state. For example, maintaining an oxygen-free state is difficult to achieve and the cost is too high. Second, intermittent production has high energy consumption and high equipment costs. It is necessary to configure feeding and discharging devices for each device separately, and the structure is complex. Third, the equipment occupies a large area.

[0003] Taking the recycling equipment used to process battery material tailings to obtain powdered positive electrode materials as an example, lithium-ion batteries use lithium-containing compounds as positive electrodes, which only contain lithium ions but no metallic lithium, usually lithium manganese oxide, lithium cobalt oxide, lithium iron phosphate, nickel cobalt manganese oxide, etc. Among them, lithium iron phosphate positive electrode sheets contain lithium iron phosphate positive electrode powder, aluminum foil and binder, and are rich in metal resources such as iron, lithium and aluminum. In the process of producing batteries, it is inevitable that tailings that cannot be used will be produced. Manufacturers need to recycle the battery materials attached to the aluminum foil, which requires separating the battery materials from the film to which they are attached, that is, peeling off and recycling the conductive current collector powder layer (positive electrode active material) attached to the aluminum foil.

[0004] At present, the commonly used methods include scraping, high-temperature incineration, organic solvent dissolution, electrolytic stripping, anaerobic cracking, etc. Among them, the anaerobic cracking method has a better recovery effect. Its processing project includes anaerobic treatment of materials, cracking reaction, cooling treatment and other steps, which require different independent reactions and treatment furnaces. As a result, the existing anaerobic cracking treatment devices are scattered, continuous production is not achieved, material transportation is complicated, and equipment investment is large, the required space is large, and the production efficiency is low, which needs further improvement.

[0056] To facilitate the understanding of the continuous production industrial furnace provided in the embodiments of the present application, its application scenario will be described first. The continuous production industrial furnace provided in the embodiments of the present application is used to perform physical or chemical reactions on materials to process the materials. However, the current industrial furnaces usually need to be completed step by step in each independent device, and the materials have to be transferred between the devices. There are the following problems: First, the material transfer cost is high, and it is difficult for the materials to reach an ideal holding state. For example, it is difficult to achieve and is also too costly to maintain an oxygen-free state. Second, the energy consumption of intermittent production is high, and the equipment cost is high. It is necessary to separately configure feeding and discharging devices for each device, and the structure is complex. Therefore, the embodiments of the present application provide a continuous production industrial furnace to overcome the deficiencies of the prior art, achieve continuous production, and have the advantages of simple structure, small floor area, and high production efficiency. The following will be described with specific embodiments.

[0057] The continuous production industrial furnace provided in the embodiments of the present application is an independent interval tunnel-type arranged continuous production industrial furnace. The continuous production industrial furnace includes a plurality of chambers that are sequentially connected. The plurality of chambers individually or in communication form an enclosed space. The plurality of chambers at least include a feeding chamber, a material reaction chamber, a transition treatment chamber, and a discharging chamber. Specifically, the continuous production industrial furnace further includes valves provided between adjacent chambers and used to conduct or close the adjacent chambers. Exemplarily, valves are provided between the feeding chamber and the material reaction chamber, between the material reaction chamber and the transition chamber, and between the transition chamber and the discharging chamber. When the material is reacting, the valves at both ends of the material reaction chamber are closed. After the reaction is completed, the valves can be opened, and the material can be transferred between adjacent chambers.

[0058] When specifically transporting materials, the continuous production industrial furnace further includes transport rollers, which are laid in multiple compartments and form a channel for transporting the material boat in the multiple compartments. The material boat is a device for transporting materials. The transport rollers are laid in each compartment and form a connected channel in the multiple compartments to continuously transport the material boat.

[0059] In addition, the continuous production industrial furnace further includes a plurality of baffle assemblies, which correspond to the multiple compartments one by one and are used to block the material boat in the corresponding compartment. When the gate between the compartments is opened or closed, the stopping of the material boat can be controlled when the gate is opened or closed.

[0060] To facilitate the understanding of the continuous production industrial furnace provided by the embodiments of the present application, an oxygen-free cracking furnace in its specific application is taken as an example for illustration. 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 it can also be other furnace bodies. In the embodiments of the present application, only for the convenience of describing the continuous production industrial furnace, the oxygen-free cracking furnace is taken as an example for illustration.

[0061] When the continuous production industrial furnace is applied to the battery field, it can specifically be an oxygen-free cracking furnace. Specifically, the oxygen-free cracking furnace is a furnace body used in the oxygen-free cracking process of battery materials. Inert gases are filled in multiple compartments of the oxygen-free cracking furnace to form oxygen-free compartments. The feeding compartment is communicated with the material reaction compartment, the material reaction compartment is communicated with the transition treatment compartment, and the transition treatment compartment is communicated with the discharging compartment.

[0062] Refer to Figure 1 as shown Figure 1The schematic structural diagram of the anaerobic cracking furnace provided by the embodiment of the present application is shown. The anaerobic cracking furnace provided by the embodiment of the present application includes a plurality of chambers 100. The plurality of chambers 100 form a closed space individually or in communication. The battery material can travel in different chambers 100 through the boat, and the battery material is subjected to corresponding processing through the functions of the chambers 100. When specifically arranged, the plurality of chambers 100 at least include a feeding chamber 110, a material reaction chamber 120, a transition treatment chamber (specifically, it can be a cooling chamber 130), and a discharging chamber 140. Among them, the feeding chamber 110 is in communication with the material reaction chamber 120, the material reaction chamber 120 is in communication with the cooling chamber 130, and the cooling chamber 130 is in communication with the discharging chamber 140. Specifically, along the moving direction of the battery material, the boat sequentially passes through the feeding chamber 110, the material reaction chamber 120, the cooling chamber 130, and the discharging chamber 140. Among them, the feeding chamber 110 is the chamber 100 for the battery material to enter the anaerobic cracking furnace, and the boat can enter the material reaction chamber 120 through the feeding chamber 110. The material reaction chamber 120 is the chamber 100 for cracking the battery material, and it is the main processing chamber 100 of the entire anaerobic cracking furnace. The battery material undergoes a cracking reaction in the material reaction chamber 120. After being cracked in the material reaction chamber 120, the boat enters the cooling chamber 130. The cooling chamber 130 is used to cool the cracked battery material to reduce its temperature. And the discharging chamber 140 is the chamber 100 for the battery material to be output from the anaerobic cracking furnace. After being processed, the battery material can be removed from the anaerobic cracking furnace through the discharging chamber 140.

[0063] When the boat moves in each chamber 100, it is transported by the transport rollers. The transport rollers are laid in the feeding chamber 110, the material reaction chamber 120, the cooling chamber 130, and the discharging chamber 140, so that the transport rollers form a channel for transporting the boat in the feeding chamber 110, the material reaction chamber 120, the cooling chamber 130, and the discharging chamber 140. The boat can move in the feeding chamber 110, the material reaction chamber 120, the cooling chamber 130, and the discharging chamber 140 driven by the transport rollers. To make each chamber 100 independent to meet the requirements of stable material reaction or chamber environment state, a valve 500 for conducting or closing adjacent chambers 100 is provided between adjacent chambers 100. The valve 500 is located between adjacent chambers 100. When the valve plate of the valve 500 is opened, the adjacent chambers 100 are in communication; when the valve plate of the valve 500 is closed, the adjacent chambers 100 form independent spaces. In specific applications, when the material reacts, the valves 500 at both ends of the material reaction chamber 120 are closed. When the material enters the material reaction chamber 120, the valve 500 connected to the feeding chamber 110 is opened. When the material enters the cooling chamber 130, the valve 500 connected to the cooling chamber 130 is opened. A gas replacement device is provided in the feeding chamber 110, the material reaction chamber 120, the cooling chamber 130, and the discharging chamber 140, and an atmosphere control device is provided in the air inlet device.

[0064] To facilitate the charging car to stop at the desired position, the anaerobic cracking furnace further includes a plurality of baffle assemblies 400. The plurality of baffle assemblies 400 correspond to the plurality of chambers one by one and are used to block the boat in the corresponding chamber 100. Exemplarily, when the chamber 100 includes a feeding chamber 110, a material reaction chamber 120, a cooling chamber 130, and a discharging chamber 140, the number of baffle assemblies 400 is three. The three baffle assemblies 400 are respectively arranged between the feeding chamber 110 and the material reaction chamber 120, between the material reaction chamber 120 and the cooling chamber 130, and between the cooling chamber 130 and the discharging chamber 140. In the above technical solution, the material reaction chamber 120 cracks and recovers battery materials by cracking. In addition, by arranging transportation rollers in each chamber 100, it is convenient for the boat carrying battery materials to move in each chamber 100. Furthermore, by arranging the baffle assemblies 400, it is convenient to control the stop of the boat in each chamber 100. The entire anaerobic cracking furnace has a simple structure.

[0065] The following specifically describes its specific structure with reference to the specific drawings.

[0066] Continue to refer to Figure 1 , first, describe the material reaction chamber 120. The material reaction chamber 120 provided in the embodiment of the present application is a cracking chamber. An ionized water inlet and a tail gas discharge pipe are arranged in the cracking chamber. During use, after the aluminum-containing lithium-ion battery cathode scrap to be processed enters the cracking chamber, ionized water mist is sprayed into the closed cracking chamber. Under the condition of approaching an anaerobic state at normal pressure, the water ions and the lithium-ion battery cathode scrap are heated to above 400 °C and maintained for a certain period of time to crack and destroy the binder, separating the cathode material from the aluminum, so that the cathode material and the aluminum foil in the aluminum-containing lithium-ion battery cathode scrap to be processed are separated to obtain a completely usable powdery cathode material.

[0067] When specifically arranged, valves 500 are installed at both ends of the material reaction chamber 120 to isolate the material reaction chamber 120 from the feeding chamber 110 and the cooling chamber 130 arbitrarily. On the one hand, it prevents the ionized water mist from entering these two chambers, and on the other hand, it prevents the heat of the material reaction chamber 120 from diffusing to these two chambers, resulting in the temperature of the material reaction chamber 120 being difficult to maintain, excessive heat consumption, and at the same time avoiding the temperature of the cooling chamber 130 being too high, which affects the cooling of the material.

[0068] In the embodiments of the present application, both the cooling chamber 130 and the discharging chamber 140 are of double-layer shell structures. Specifically, the cooling chamber 130 has a double-layer shell, and cooling water is filled in the interlayer between the double-layer shells; the discharging chamber 140 also has a double-layer shell, and cooling water is filled in the interlayer between the double-layer shells; a cooling device is further included, and the cooling device is respectively communicated with the interlayer of the cooling chamber 130 and the interlayer of the discharging chamber 140 through pipelines. The cooling device can be a condenser, and the condenser is respectively communicated with the interlayers in the cooling chamber 130 and the discharging chamber 140 through pipelines to form a circulation loop. So that the low-temperature water provided by the condenser can be continuously supplemented into the interlayer to cool the cooling chamber 130 and the discharging chamber 140.

[0069] In addition, the cooling chamber 130 is provided with a gas inlet and exhaust device and an oxygen analyzer. The oxygen analyzer monitors the oxygen molecule content of the gas in the chamber in real time, and the material can enter the discharging chamber 140 only after being cooled to a certain degree through the cooling chamber 130.

[0070] The discharging chamber 140 is provided with a gas inlet and exhaust device 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 boat comes out through the openable or closable discharging port and enters the external discharging roller path 700.

[0071] The anaerobic pyrolysis furnace provided by the embodiments of the present application may further include a feeding roller path 600 and a discharging roller path 700. Among them, the feeding roller path 600 is located outside the feeding chamber 110 and is used to transfer the material boat to the feeding chamber; the discharging roller path 700 is located outside the discharging chamber 140 and is used to carry the material boat transferred out of the discharging chamber 140. When in use, outside the anaerobic pyrolysis furnace, the material boat is transported through the feeding roller path 600, and the first trolley cylinder 800 arranged on the feeding roller path 600 is used to push the material boat into the feeding chamber 110. Similarly, when the discharging roller path 700 cooperates with the discharging chamber 140, it is used to carry the material boat removed from the discharging chamber 140. Specifically, the discharging chamber 140 is provided with a second trolley cylinder 900, and the second trolley cylinder 900 is used to push the material boat from the discharging chamber 140 to the discharging roller path 700.

[0072] Refer to together Figure 2 and Figure 3, for communication with the outside world, access ports cooperating with the boat are respectively provided in the feed chamber 110 and the discharge chamber 140. To facilitate the control of the connection between the anaerobic cracking furnace and the outside world, the anaerobic cracking furnace further includes a door closing assembly 200, and the door closing assembly 200 includes a door panel 210, a driving link 220 and a telescopic mechanism 230. Among them, the door panel 210 is used to block the access port. When the door panel 210 covers the access port, the door panel 210 blocks the access port. When the door panel 210 is moved away, the access port is opened, and materials can enter and exit through the access port. The telescopic mechanism 230 serves as a driving mechanism, which is used to drive the door panel 210 to rotate relative to the access port to realize the opening and closing of the access port. The driving link 220 serves as a transmission mechanism to convert the telescopic motion of the telescopic mechanism 230 into the rotational motion of the door panel 210. The specific structure of the baffle will be described in detail with reference to the specific drawings below.

[0073] Refer to together Figure 2 and Figure 3 , Figure 2 shows a front schematic view of the feed chamber 110. When the door panel cooperates with the feed chamber 110, the door closing assembly 200 further includes a first support seat 240, and the first support seat 240 is fixed to the feed chamber 110. The driving link 220 is hinged to the first support seat 240. One end of the driving link 220 is hinged to the telescopic end of the telescopic mechanism 230, and the other end is fixedly connected to the door panel 210. The telescopic mechanism 230 is hinged to the feed chamber 110 or the discharge chamber 140. When the telescopic end of the telescopic mechanism 230 expands and contracts, it can drive the driving link 220 to rotate, and then drive the door panel 210 to rotate around the first support seat 240. In Figure 2 and Figure 3 an example is given with the feed chamber 110 as an example. On the discharge chamber 140, the door closing assembly 200 is also arranged in the same way. In the embodiments of the present application, only the feed chamber 110 is used for illustration.

[0074] Specifically, the driving link 220 includes a first link 221 and a second link 222. Among them, the first link 221 is fixedly connected to the second link 222. When cooperating with the first support seat 240, the connection part of the first link 221 and the second link 222 is rotatably connected to 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 directions of the first link 221 and the second link 222. In addition, when the driving link 220 is connected to the telescopic mechanism 230 and the door panel 210, the first link 221 is hinged to the telescopic end of the telescopic mechanism 230; one end of the second link 222 away from the first link 221 is fixedly connected to the door panel 210. Combining Figure 1 it can be seen that when the telescopic end of the telescopic mechanism 230 expands and contracts, it can drive the first link 221 and the second link 222 to rotate around the first support seat 240, and then drive the door panel 210 to rotate to realize blocking or opening the access port.

[0075] Continue to refer to Figure 2 As shown in, the first link 221 is inclined relative to the second link 222, and the included angle between the two is greater than or equal to 90°, that is, the first link 221 and the second link 222 form a bent link, and the bent included angle is greater than 90°, such as different angles like 90°, 120°, 150°, etc. Further, the included angle between the first link 221 and the second link 222 can be less than 180°. When the above structure is adopted, the bent driving link 220 can facilitate the arrangement of the door panel 210 and the telescopic mechanism 230. Exemplarily, the opening direction of the through opening of the feeding chamber 110 is inclined upward. When the door panel 210 covers the through opening, it is also inclined. At this time, when the driving link 220 uses a bent link, the telescopic mechanism 230 can be conveniently arranged on the feeding chamber 110. As Figure 1 As shown in, when the telescopic direction of the telescopic mechanism 230 is the horizontal direction, the bent driving link 220 can be used to drive the door panel 210 away from the through opening or block the through opening.

[0076] When the driving link 220 cooperates with the telescopic mechanism 230 and the door panel 210, the length of the first link 221 is less than the length of the second link 222. When adopting this structure, the driving link 220 can be used as a lever. The setting method that the length of the first link 221 is less than the length of the second link 222 enables the telescopic mechanism 230 to drive the door panel 210 to have a larger movement stroke when using a smaller telescopic stroke. Thus, when the through opening is opened, the door panel 210 can avoid the through opening, enabling the material to obtain a larger access space.

[0077] In addition, when adopting the above structure, the door panel 210 is not directly connected to the through opening, so that when the through opening is opened, the door panel 210 does not occupy the feeding and discharging space of the through opening, improving the convenience of material access.

[0078] It can be seen from the above description that the door closing assembly 200 provided by the embodiment of the present application drives the opening and closing of the door panel 210 by using the lever principle, and by using the cooperation of two different links, the telescopic mechanism 230 can drive the door panel 210 to obtain a larger stroke with a smaller stroke, so that the through passage of the material is not affected after the door panel 210 is opened.

[0079] Continue to refer to Figure 2 and Figure 3In an practicable solution, the number of the second connecting rods 222 is two; the two second connecting rods 222 are arranged on both sides of the telescopic mechanism 230. The driving connecting rod 220 also includes a cross bar 223 rotatably connected to the first support seat 240, the two second connecting rods 222 are respectively fixedly connected to the cross bar 223, and the first connecting rod 221 is fixedly connected to the cross bar 223. That is, the first connecting rod 221 and the second connecting rod 222 are fixedly connected through the cross bar 223. When the first supporting seat 240 is matched, the first connecting rod 221 and the second connecting rod 222 are rotatably connected to the first supporting seat 240 through the cross bar 223, so that the first connecting rod 221 and the second connecting rod 222 can rotate around the first supporting seat 240. When the two second connecting rods 222 are fixedly connected to the door panel 210, the force of the door panel 210 can be improved, and the force of the door panel 210 can be balanced. In addition, the force applied by the telescopic mechanism 230 to the door panel 210 is increased, thereby ensuring the stability of the door panel 210 when it is opened and the force of the door panel 210 when it blocks the opening.

[0080] Specifically, the two second connecting rods 222 are symmetrically arranged on opposite sides of the telescopic mechanism 230. That is, the two second connecting rods 222 are symmetrically arranged on both 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 door panel 210 is subjected to balanced force.

[0081] Continue to refer Figure 2 When the first support seat 240 is specifically provided, the number of the first support seat 240 is two, and the two first support seats 240 are arranged on both sides of the crossbar 223 and are respectively rotatably connected to the crossbar 223. The two first support seats 240 are respectively rotatably connected to the two ends of the crossbar, so that the stability of the crossbar 223 during rotation can be improved. In addition, the two second connecting rods 222 are located between the two first support seats 240. Thereby, the stability of the driving connecting rod 220 during rotation is further improved.

[0082] Continue to refer Figure 2 and Figure 3 When the first support seat 240 is specifically set, the first support seat 240 is set at the end surface where the opening is located on the feed chamber 110 or the discharge chamber 140; and the first support seat 240 is set in an inclined direction away from the opening. When the above-mentioned setting is adopted, the first support seat 240 is prevented from affecting the space for materials to enter and exit the opening. In addition, setting the first support seat 240 at this position also facilitates the setting of the driving connecting rod 220.

[0083] As an optional solution, when the driving connecting rod 220 is connected to the door panel 210, the length direction of the second connecting rod 222 is parallel to the plane of the door panel 210 away from the opening. When the above method is adopted, the space occupied by the second connecting rod 222 can be reduced, and the space occupied by the entire device can be reduced.

[0084] In another feasible solution, the position where the second link 222 is hinged to the door panel 210 is close to the center of gravity of the door panel 210. In this state, when the door panel 210 rotates, it can be considered that the center of gravity of the door panel 210 is located on the line connecting the positions where the two second links 222 are fixedly connected to the door panel 210, thereby improving the force on the door panel 210.

[0085] In the above technical solution, the telescopic mechanism 230 can adopt different telescopic mechanisms. Exemplarily, the telescopic mechanism 230 can be a telescopic air cylinder, a telescopic hydraulic cylinder or a linear motor. When specifically setting, different driving mechanisms can be selected according to needs.

[0086] Continue to refer to Figure 1 , after the boat enters the anaerobic cracking furnace, it is transported by the transport rollers. When using the transport rollers 300, the number of the transport rollers 300 is multiple, and the multiple transport rollers 300 are arranged along the length direction of the chamber 100. Each transport roller 300 is penetrated through the chamber 100 of the anaerobic cracking furnace, and part of it is located inside the chamber 100 and part of it is exposed outside the chamber 100. Among them, the part of the transport roller 300 located inside the chamber 100 is used to cooperate with the boat to drive the boat to move through the rotation of the transport roller 300. The part of the transport roller 300 located outside the chamber 100 is used as a power connection part to drive the transport roller 300 to move through the sprocket 320 or other transmission mechanisms. When adopting this method, the driving mechanism that drives the transport roller 300 to rotate can be located outside the chamber 100 and does not occupy the space inside the chamber 100. The cooperation structure between the transport roller 300 and the chamber 100 will be described in detail below with reference to the drawings.

[0087] Refer to together Figure 4 and Figure 5 , Figure 4 shows a schematic structural view of the transport roller 300 penetrated through the chamber 100, Figure 5 shows a partial enlarged view of the cooperation between the transport roller 300 and the chamber 100. The transport roller 300 provided by the embodiment of the present application mainly includes a sleeve 330, a roller shaft 310 and a bearing seat 340. Among them, the roller shaft 310 is the main structure of the transport roller 300, and it is an overall round shaft. When cooperating with the chamber 100, the roller shaft 310 is penetrated through the side wall of the chamber 100, and part of it is located inside the chamber 100 and part of it is located outside the chamber 100. The part of it located inside the chamber 100 is used to cooperate with the boat. The sleeve 330 and the bearing seat 340 are used as supporting structures to rotatably connect the roller shaft 310 with the side wall of the chamber 100.

[0088] Specifically, the sleeve 330 is inserted through the side wall of the cabin 100 and is hermetically connected to the side wall. For example, the sleeve 330 can be hermetically connected to the side wall of the cabin 100 by welding, or the sleeve 330 is hermetically connected to the side wall of the cabin 100 by sealant. When the sleeve cooperates with the side wall of the cabin 100, the roller shaft 310 is inserted through the sleeve 330. Specifically, the sleeve has a hollow cavity, and the roller shaft 310 is inserted into the cavity inside the sleeve 330. Moreover, one end of the roller shaft 310 is exposed outside the bearing seat 340, and a sprocket 320 is fixedly connected to the end of the roller shaft 310 exposed outside the bearing seat 340. The driving mechanism can drive the sprocket 320 to move through a transmission belt to drive the roller shaft 310 to rotate.

[0089] As an alternative solution, the roller shaft 310 is a stepped shaft, and the diameter of the part of the roller shaft 310 located inside the cabin 100 and exposed outside the sleeve 330 is smaller than the inner diameter of the sleeve 330. So that the roller shaft 310 can be directly inserted from the end exposed outside the sleeve 330 into the cabin 100, which facilitates the assembly and replacement of the roller shaft 310.

[0090] As an implementable solution, part of the sleeve 330 passes through the side wall of the cabin 100 and is exposed inside the cabin 100, while the other part is exposed outside the cabin 100, so that the sleeve 330 has a longer length to cooperate with the roller shaft 310.

[0091] When assembling the bearing seat 340, the bearing seat 340 is fixedly and hermetically connected to the sleeve 330. Specifically, the bearing seat 340 is nested inside the sleeve 330 and is fixedly connected to the sleeve 330. A bearing 390 is fixed inside the bearing seat 340, and the roller shaft 310 is rotatably connected to the sleeve 330 through the bearing 390 to reduce the frictional force of the roller shaft 310 during rotation through the bearing 390.

[0092] When the bearing seat 340 is fixedly connected to the sleeve 330, a first connecting flange 331 can be provided on the sleeve 330, and a second connecting flange 341 is provided on the bearing seat 340 at the same time, and the first connecting flange 331 and the second connecting flange 341 are fixedly connected by a threaded connector (such as a bolt or a bolt assembly) to achieve the fixed connection between the bearing seat 340 and the sleeve 330. It should be understood that when the bearing seat 340 is fixedly connected to the sleeve 330, part of the bearing seat 340 is inserted into the hollow cavity of the sleeve 330 and can be in interference fit with the sleeve 330. To ensure the stability between the sleeve 330 and the bearing seat 340.

[0093] Of course, in addition to the above example of realizing the fixed connection between the bearing seat 340 and the sleeve 330 through the flange, other methods can also be used to fixedly connect the bearing seat 340 and the sleeve 330. For example, the bearing seat 340 and the sleeve 330 are fixedly connected by welding or bonding, which will not be exemplified one by one in the embodiments of the present application.

[0094] When the bearing housing 340 is hermetically connected to the sleeve 330, a first sealing washer 380 is provided on the second connecting flange 341, and the first connecting flange 331 and the second connecting flange 341 are hermetically connected through the first sealing washer. Thus, the seal between the bearing housing 340 and the sleeve 330 is achieved through the seal between the first connecting flange 331 and the second connecting flange 341. To avoid the gap between the bearing housing 340 and the sleeve 330 from affecting the sealing performance of the anaerobic cracking furnace. The first sealing washer can be a rubber sealing ring or a resin sealing ring, and of course, it can also be a sealing ring made of other materials.

[0095] When the bearing housing 340 cooperates with the roller shaft 310, a heat insulation material layer 360 is provided inside the bearing housing 340. The heat insulation material layer 360 axially wraps the roller shaft 310 to fill the gap between the roller shaft 310 and the bearing housing 340 through the heat insulation material layer 360, and isolate the heat exchange between the inside and outside of the chamber 100 through the heat insulation material layer 360. When specifically setting the heat insulation material layer 360, the bearing housing 340 has a stepped hole; among them, the hole with a larger diameter is used to fix the outer ring of the bearing 390; a groove for accommodating the heat insulation material layer 360 is provided in the hole with a smaller diameter. As Figure 5 shown, the hole with a larger diameter is located on the side where the second connecting flange 341 is located and outside the sleeve 330 to ensure that the bearing 390 is not affected by the sleeve 330 when it cooperates with the bearing housing 340. In addition, the hole with a smaller diameter is located inside the sleeve 330, and the groove is opened on the inner wall of the hole with a smaller diameter and is arranged around the inner wall. The length direction of the groove is along the length direction of the bearing housing 340, so that when the heat insulation material layer 360 is filled in the groove, it has a certain thickness along the length direction of the bearing housing 340 to ensure the heat insulation effect.

[0096] The above-mentioned heat insulation material layer 360 can be prepared from different heat insulation materials. Exemplarily, the heat insulation material can be a porous material. Such materials use their internal pores to insulate heat because the thermal conductivity of the air or inert gas in the pores is relatively low, such as foam materials and fiber materials. Or the heat insulation material layer 360 can also be different heat insulation layers such as a rock wool board layer, an expanded polystyrene board layer, an extruded polystyrene board layer, etc.

[0097] In an alternative embodiment, a second sealing washer 370 is provided on the bearing housing 340; the bearing housing 340 and the roller shaft 310 are hermetically connected through the second sealing washer 370. Combining Figure 4 and Figure 5It can be seen that there is a seal between the sleeve 330 and the side wall of the chamber 100, a seal between the bearing seat 340 and the sleeve 330 (through the first gasket), and also a seal between the roller shaft 310 and the bearing seat 340 (through the second gasket), so that a seal is also achieved between the roller shaft 310 and the side wall of the chamber 100. In addition, a heat insulation material layer 360 is filled between the roller shaft 310 and the bearing seat 340, which also improves the heat exchange between the inside and outside of the chamber 100 and improves the performance of the anaerobic cracking furnace.

[0098] As an alternative embodiment, the second sealing washer 370 is a sealing washer made of a self-lubricating material. For example, a self-lubricating silicone rubber sealing ring is used. A self-lubricating silicone rubber sealing ring is made by adding a lubricating oil special material into the silicone rubber material. After the rubber product is vulcanized and formed, the surface of the silicone rubber sealing ring is smooth and lubricating, which can play a role in reducing friction. For example, polytetrafluoroethylene (PTFE) has excellent properties such as chemical stability, high and low temperature resistance, low friction coefficient, and self-lubrication, so polytetrafluoroethylene material can be selected. Of course, other self-lubricating materials such as nitrile rubber and silicone rubber materials can also be selected.

[0099] In an alternative embodiment, along the length direction of the roller shaft 310; the heat insulation material layer 360 is relatively farther from the sprocket 320 than the second sealing washer 370. So that the second sealing washer 370 isolates the heat insulation material layer 360 from the external environment and avoids the influence of external impurities on the heat insulation performance of the heat insulation material layer 360.

[0100] As an alternative embodiment, the transport roller 300 further includes a thrust cover 350, which is fixedly connected to the bearing seat 340 and is 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 outside the sleeve 330 and is fixedly connected to the bearing seat 340 by bolts or screws. The bearing 390 is fixed by the cooperation of the thrust cover 350 and the stepped hole in the bearing seat 340, and the influence of the shaking of the bearing 390 on the rotation of the roller shaft 310 is reduced.

[0101] It can be seen from the above description that the transport roller 300 provided by the embodiment of the present application is provided with a heat insulation material layer 360 in the bearing seat 340 to isolate the heat in the chamber 100, avoid reducing the sealing performance of the entire anaerobic cracking furnace due to the penetration of the roller shaft 310, and improve the use effect of the anaerobic cracking furnace.

[0102] When transporting the boat, the boat is transported within each chamber 100 by the transport rollers. Additionally, valves 500 are provided within different chambers 100 to isolate each chamber 100. The valve 500 is disposed between adjacent chambers 100 and is used to conduct or close the adjacent chambers 100. Exemplarily, taking the feed chamber 110 and the material reaction chamber 120 as an example. When the material has not entered the feed chamber 110, the valve 500 is closed, and the feed chamber 110 is isolated from the material reaction chamber 120. When the boat is transported by the transport rollers to the connection between the feed chamber 110 and the material reaction chamber 120, the valve 500 is opened, and the boat can smoothly enter the material reaction chamber 120 from the feed chamber 110.

[0103] To facilitate the boat to stop in the material reaction chamber 120, in the embodiment of the present application, the passage or stop of the boat is controlled by a baffle assembly.

[0104] Refer to Figure 6 , Figure 6 shows a side schematic view of the anaerobic cracking furnace when applied within the chamber 100. When the boat is transported in the anaerobic cracking furnace, it is transported by the transport rollers 300 provided within the chamber 100. Among them, the number of transport rollers 300 is multiple, and the multiple transport rollers 300 are arranged at intervals along the length direction of the chamber 100 to form a passage for transporting the boat. When it is necessary to stop the boat, it is achieved by blocking the boat with the baffle assembly 400 provided in the embodiment of the present application. Specifically, the baffle assembly 400 is disposed within the chamber 100 and is located between two adjacent transport rollers 300. When it is necessary to block the boat, the baffle assembly 400 is exposed outside the support surface of the transport rollers 300 that support the boat, so that it can press against the boat to block the boat from moving forward. The specific structure of the baffle assembly 400 will be described in detail below.

[0105] Refer to together Figure 7 and Figure 8 , Figure 7 shows a front schematic view of the baffle assembly 400 when applied within the chamber 100, Figure 8 shows a front structural schematic view of the baffle assembly 400. The baffle assembly 400 provided in the embodiment of the present application mainly includes a second support seat 410, a baffle 420, a first connecting rod 430, a second connecting rod 440, and a telescopic driving mechanism 450. Among them, the second support seat 410 is fixed within the chamber 100, and it serves as the support structure of the entire baffle assembly 400 to support the baffle 420. The baffle 420 serves as the functional component of the baffle assembly 400, and it is used to cooperate with the boat to achieve blocking and releasing of the boat. The first connecting rod 430, the second connecting rod 440, and the telescopic driving mechanism 450 are used to form a link driving mechanism to achieve blocking and releasing of the boat by driving the baffle 420 to rotate.

[0106] Specifically, when the second support base 410 is fixed, it is fixed to the side wall inside the chamber 100, such as Figure 7 As shown in the figure, when the second support base 410 is fixed inside the chamber 100, it is located below the transport roller 300, and its height is lower than the support surface of the transport roller 300 for supporting the boat, so as to ensure that the setting of the second support base 410 does not affect the movement of the boat. When specifically fixing, the second support base 410 can be fixed to the side wall of the chamber 100 by bolts or screws. Of course, it can also be fixed inside the chamber 100 by bonding or welding methods.

[0107] When supporting the baffle 420, the baffle 420 is rotatably connected to the second support base 410. Specifically, a first rotating shaft 460 is passed through the second support base 410, and the baffle 420 is rotatably connected to the second support base 410 through the first rotating shaft 460. In a specific implementation, the axis of the first rotating shaft 460 is perpendicular to the axis of the transport roller 300, so that the path passed by the baffle 420 during rotation is perpendicular to the axis of the transport roller 300, thereby ensuring that the space occupied by the baffle 420 during rotation is small.

[0108] Referring together to Figure 8 and Figure 4 , in an alternative embodiment, the second support base 410 may include a first support plate 411 and a second support plate 412 arranged opposite to each other; the baffle 420 is located between the first support plate 411 and the second support plate 412, and the first rotating shaft 460 is rotatably connected to the first support plate 411 and the second support plate 412 respectively. In this way, the opposite ends of the rotating shaft can be supported by the first support plate 411 and the second support plate 412 to ensure the stability of the first rotating shaft 460 during rotation, and the baffle 420 is located between the two support plates, which also enhances the stability of the baffle 420 during rotation.

[0109] When the baffle 420 is rotatably connected to the second support base 410 through the first rotating shaft 460, the first rotating shaft 460 can be rotatably connected to the second support base 410, and the first rotating shaft 460 is fixedly connected to the baffle 420 to realize the rotation of the baffle 420 relative to the second support base 410. It should be understood that when the first rotating shaft 460 is rotatably connected to the second support base 410, the first rotating shaft 460 can be rotatably connected to the second support base 410 through a bearing.

[0110] In an embodiment of the present application, the baffle 420 is a long strip-shaped structure, and the length direction thereof is perpendicular to the axis direction of the first rotating shaft 460. The baffle 420 has two ends, and one of the ends is a blocking end, which is used to abut against the boat to limit the boat. Specifically, when the baffle 420 is in use, the baffle 420 has two different states. Exemplarily, when the baffle 420 rotates to the first position, the blocking end is exposed on the side where the transport roller 300 supports the boat. In this state, when the boat travels to the baffle assembly 400, the blocking end can press against the boat to limit the boat. When the baffle 420 rotates to the 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 for supporting the boat, and the boat can pass through the baffle assembly 400 without hindrance when it travels to the baffle assembly 400.

[0111] When driving the baffle 420, it is driven by the first link 430, the second link 440 and the telescopic driving mechanism 450. Specifically, when connecting, the first link 430 is fixedly connected to the baffle 420, the second link 440 is rotatably connected to the first link 430, and the second link 440 is rotatably connected to the telescopic driving mechanism 450. Combining Figure 8 with the structure shown, when the first link 430 is fixedly connected to the baffle 420, the blocking end and the first link 430 are located on both sides of the first rotating shaft 460. And the two ends of the second link 440 are respectively connected to the first link 430 and the telescopic driving mechanism 450. Specifically, one end of the second link 440 is rotatably connected to the first link 430 through the second rotating shaft 470, and the other end of the second link 440 is connected to the telescopic driving mechanism 450 through the third rotating shaft 490. It should be understood that the axes of the above-mentioned first rotating shaft 460, second rotating shaft 470 and third rotating shaft 490 are parallel.

[0112] When driving the baffle 420 to rotate, the telescopic driving mechanism 450 can pull the second link 440 through its own telescopic movement, and the second link 440 will pull the first link 430, and finally drive the baffle 420 to rotate around the first rotating shaft 460. Taking Figure 8 the state of the baffle assembly 400 shown as an example, when the telescopic driving mechanism 450 retracts, it can pull the second link 440 to move to the right, and pull the baffle 420 to rotate counterclockwise through the first link 430. The blocking end of the baffle 420 is lowered until it is hidden between the transport rollers 300, so as to release the block on the boat. Of course, when it is necessary to block the boat, the telescopic driving mechanism 450 can be extended outwards, push the second link 440 to move to the left, and drive the baffle 420 to rotate clockwise to restore to Figure 8 the position where the baffle 420 is located in

[0113] In an alternative embodiment, when the baffle 420 is fixedly connected to the first rotating shaft 460, the first connecting rod 430 can be fixedly connected to the baffle 420 through the first rotating shaft 460. Specifically, the baffle 420 is fixed to the first rotating shaft 460, and the first connecting rod 430 is also fixedly connected to the first rotating shaft 460, thereby realizing the fixed connection between the baffle 420 and the first connecting rod 430.

[0114] In an implementable 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 to the end of the first rotating shaft 460 exposed at the end of the first support plate 411. This facilitates arranging 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.

[0115] When the first connecting rod 430 is connected to the second connecting rod 440, to improve the stability of the second connecting rod 440 during rotation. The first connecting rod 430 may include two sub-connecting rods arranged oppositely, and both sub-connecting rods are fixedly connected to 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 to 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 when the second connecting rod 440 is connected to the first connecting rod 430.

[0116] The telescopic driving mechanism 450 can be a telescopic air cylinder or a telescopic hydraulic cylinder to achieve driving through the telescopic movement of the piston rod of the telescopic air cylinder or the telescopic hydraulic cylinder. Specifically, when the second connecting rod 440 is connected to the telescopic driving mechanism 450, the piston rod of the telescopic air cylinder or the telescopic hydraulic cylinder is rotatably connected to the second connecting rod 440. Exemplarily, a connecting head 480 is provided at the end of the piston rod; the connecting head 480 is of a U-shaped structure; the end of the second connecting rod 440 is inserted into the U-shaped structure and is rotatably connected to 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.

[0117] When specifically arranging the telescopic driving mechanism 450, the telescopic driving mechanism 450 is fixed inside 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 driving mechanism 450 is parallel to the length direction of the transport roller 300. When installing the baffle assembly 400, it is convenient to place the entire mechanism in the gap between two adjacent transport rollers 300.

[0118] In an alternative embodiment, the length direction of the first connecting rod 430 is the same as the length direction of the baffle 420. When adopting this connection method, the forces on both sides of the first rotating shaft 460 can be relatively balanced.

[0119] As can be seen from the above description, the baffle assembly 400 provided by the embodiment of the present application controls the rotation of the baffle 420 through the cooperation of the baffle 420 and the connecting rod and the telescopic driving mechanism 450 that cooperate with the baffle 420, so as to block or allow the boat to pass through in the cabin 100. In addition, the structure of the baffle assembly 400 is simple, with high reliability and small occupied space. 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 driving mechanism 450. The structure strength of the baffle 420, the second support seat 410 and the first rotating shaft 460 can be used to block the boat, and the blocking force will not be transmitted to the telescopic driving mechanism 450, reducing the impact on the telescopic driving mechanism 450.

[0120] During specific use, when the boat loaded with scraps comes to the opening (feed inlet) of the feed cabin 110 through the feed roller table 600, at this time, the door panel 210 of the feed inlet is opened by the telescopic mechanism 230, and the boat is pushed into the feed cabin 110, and the transport roller moves the boat to a suitable position. When the boat is full, the door panel of the feed cabin 110 is closed, and through gas replacement, an anaerobic state is maintained in the feed cabin 110 and other cabins. The valve 500 between the material reaction cabin 120 and the feed cabin 110 is opened, and the boat enters the material reaction cabin 120, and this valve 500 is closed. The temperature of the material reaction cabin 120 is raised to the required temperature, and at the same time, the water ion generation system sprays ionized water into the material reaction cabin 120. After a period of cracking. The valve 500 between the cracking cabin and the cooling cabin 130 is opened, and the boat enters the cooling cabin 130 through the cracking transport roller. When all the boats in all the cracking cabins enter the cooling cabin 130, this valve 500 is closed again. The cooling cabin 130 is a water-cooled double-layer jacketed cabin body, and the circulating cooling water continuously reduces the temperature in the cabin. The materials entering the cooling cabin 130 are thus continuously cooled, and finally reach the required out-of-cabin temperature. The boat passing through the cooling cabin 130 enters the discharge cabin 140, and the door panel of the discharge port is opened, and the boat enters the feed cabin 110, the material reaction cabin 120, the cooling cabin 130 and the discharge cabin 140 in sequence. Through gas replacement, an anaerobic state is always maintained.

[0121] As can be seen from the above description, the anaerobic cracking furnace provided by the embodiment of the present application cracks and recovers battery materials by using the material reaction cabin for cracking. In addition, by arranging transport rollers in each cabin 100, it is convenient for the boat carrying the battery materials to move in each cabin 100. In addition, through the arranged baffle assembly, it is convenient to control the stop of the boat in each cabin 100. The whole anaerobic cracking furnace has a simple structure.

[0122] In addition, when transporting materials to the feed cabin or removing materials from the discharge cabin to the outside of the furnace body, the feed cabin is connected to the feed roller table, and a horizontal feeding device or longitudinal feeding can be provided. The discharge cabin is connected to the discharge roller table, and a horizontal discharging device or longitudinal discharging can be provided.

[0123] As can be seen from the above description, a continuous anaerobic roller-type industrial furnace provided by an embodiment of the present application is provided with a feeding chamber, a material reaction chamber, a cooling chamber, and a discharging chamber. The feeding chamber is connected to a feeding roller path, and a horizontal feeding roller path or a vertical feeding roller path can be adopted. The discharging chamber is connected to a discharging roller path, and a horizontal discharging roller path or a vertical discharging roller path can be adopted. Valves are provided between the feeding chamber and the material reaction chamber and between the material reaction chamber and the cooling chamber. When the material is reacting, the valves at both ends of the material reaction chamber are closed. When the material enters the material reaction chamber, the valve connected to the feeding chamber is opened. When the material enters the cooling chamber, the valve connected to the cooling chamber is opened. Gas replacement devices are provided in the feeding chamber, the material reaction chamber, the cooling chamber, and the discharging chamber, and the intake device is provided with an atmosphere control device.

[0124] The utility model mainly relates to fields such as heating reaction and purification of powder materials, and is particularly suitable for the recovery of battery material tailings, the reduction and purification of metal-containing materials, and the drying of powder materials.

[0125] Continuous kiln car furnaces (belt type, walking beam type, traction type, rotary hearth type) generally use the bottommost steel rails as the tracks for the movement of the material cars inside the furnace, and drive the material car sprockets through chains or drive the material cars inside the kiln furnace by motors. Therefore, the inside of the kiln furnace is a full channel, and it is impossible to achieve multiple divisions along the cross-section of the kiln furnace to realize independent functional areas inside the kiln furnace. Moreover, the kiln furnace cannot be isolated from the external air, and it is impossible to ensure an anaerobic function inside the kiln furnace. Belt type, walking beam type, traction type, and rotary hearth type continuous electrothermal and gas thermal furnaces are the same as industrial kiln car furnaces. They cannot achieve multiple divisions along the cross-section of the furnace chamber, cannot be isolated from the external air, and cannot ensure an anaerobic function inside the furnace chamber. The continuous pusher furnace mainly realizes the movement of the boats inside the furnace by pushing the boats at the feeding end and through the force transmission between the boats, but it cannot physically divide each functional area inside the furnace chamber, so it cannot ensure the relative independence of the atmosphere and environment in each area inside the furnace.

[0126] The purpose of the utility model is to achieve good sealing inside the continuous industrial furnace, ensure an anaerobic state inside the furnace chamber through gas replacement, and at the same time achieve multiple divisions of the cross-section of the furnace chamber inside the furnace channel to maximize the different functions of each action chamber inside the furnace chamber.

[0127] In addition, in the above technical solution, the continuous production industrial furnace includes a plurality of chambers that are independent of each other and arranged continuously. Each chamber can be independently closed and has a different atmosphere inside the furnace. Two or more chambers can also be interconnected. The provided transport rollers penetrate through each chamber, and the material can be continuously pushed between each chamber. The material is always in the loading car, but is in different atmospheres by staying in different chambers to complete each stage of material processing.

[0128] Specifically, the continuous production industrial furnace provided by the present application can meet the processing requirements of the material to be processed at different stages. For example, when the material needs to be heated and reacted, it is made to stay in the chamber with specific corresponding reaction conditions, and the corresponding process conditions are created by enclosing the chamber. For example, an inert gas is input into the chamber to form an anaerobic atmosphere, or the chamber is evacuated to form a vacuum atmosphere, etc. After the reaction is completed, it can be seamlessly pushed into the adjacent chamber to enter the subsequent processing stage, and the process conditions of the chamber are set according to the subsequent processing requirements, such as cooling down. Each chamber works independently, and the residence and pushing of the material are completed through the material boat, and different batches of materials are continuously processed, thus realizing continuous production.

[0129] Its technical effects are reflected in: 1. The material does not need to be transferred between various devices, but is directly pushed by the conveying roller. The pushing of the material can be completed by connecting the chambers 100 and starting the conveying roller. The material transfer cost is greatly reduced, and the material can maintain an ideal state at a relatively low cost without unnecessary treatments such as cooling solely for material transfer. 2. Continuous production is realized. The corresponding reaction or post-treatment is completed by the material staying in each independent section arranged in a tunnel-like manner. The material pushing path is optimized, and each independent space can efficiently achieve batch processing, with significantly reduced energy consumption. 3. The equipment cost is greatly reduced and the floor area is small. There is no need to separately configure feeding and discharging devices for each device, and the structure is simple.

[0130] In addition, by arranging transport rollers in each chamber, it is convenient for the material boat carrying the material to move and be pushed in each chamber. In addition, through the arranged baffle assembly, it is convenient to control the stop of the material boat in each chamber. The entire industrial furnace has a simple structure.
