Description

Technical Field

[0001] This utility model relates to a battery processing equipment, and more particularly to an oxygen-free pyrolysis equipment. Background Technology

[0002] Waste batteries contain heavy metals (lead, cadmium, mercury), electrolytes, and other chemicals. Although they contain toxic substances, lithium, cobalt, nickel, and other core materials in waste batteries can be recycled and reused. During recycling, the batteries are usually crushed and then pyrolyzed. High-temperature pyrolysis of batteries, also known as thermal decomposition, is a process that uses high-temperature heating to treat waste batteries in an oxygen-free or oxygen-deficient environment, which avoids the generation of harmful substances and the waste of energy.

[0003] In traditional battery pyrolysis technology, the broken fragments are fed into a pyrolysis furnace and heated to a set temperature in a strictly controlled oxygen-free environment. Organic materials such as the separator (PP / PE), binder (PVDF), and residual electrolyte in the electrode materials undergo thermal decomposition, turning into pyrolysis gas and a small amount of residual carbon. The pyrolysis gas is discharged as exhaust gas, while other solid materials are sorted later. Existing exhaust gas collection equipment is often located at the front or rear of the pyrolysis cylinder to collect and discharge the waste gas generated during pyrolysis. This process does not affect the rotation of the pyrolysis cylinder itself. However, since the pyrolysis cylinder is quite long in actual use, waiting for the waste gas from the middle or rear sections to reach the exhaust position at the front requires a considerable amount of time. Furthermore, waste gas that cannot be discharged in time at this position will hinder heat dissipation, thus affecting the pyrolysis effect. Utility Model Content

[0004] This invention provides an oxygen-free pyrolysis device that can quickly remove the pyrolysis gas generated at each position of the pyrolysis cylinder and retain some powder at the temperature zone separation position, thereby allowing the battery fragments to be pyrolyzed more thoroughly, effectively solving the above-mentioned problems.

[0005] This utility model is implemented as follows: An anaerobic pyrolysis device includes a feeder connected to a crushing mechanism, the feeder being connected to a hollow rotating drum, a main drive unit being connected to the lower end of the hollow rotating drum, the hollow rotating drum being connected to a pyrolysis drum, a lower discharge drum being connected to the discharge end of the pyrolysis drum, the lower discharge drum being connected to a conveyor belt, and further comprising: The connecting gas guiding structure includes a partition chamber outside the pyrolysis cylinder. The pyrolysis cylinder comprises several pyrolysis sections, which are connected by a connector. When one pyrolysis section rotates, it drives the other pyrolysis section to rotate via the connector. The connecting gas guiding structure includes an outer bonding frame disposed inside the partition chamber. The outer bonding frame is connected between two pyrolysis sections. An extension section is connected to the side of the outer bonding frame facing the pyrolysis section. A bonding element is disposed on the extension section facing the inside of the pyrolysis section. The bonding element is tightly attached to the inner wall of the pyrolysis section. An outer auxiliary frame is disposed on the outside of the outer bonding frame. A discharge pipe is disposed on the outside of the outer bonding frame. Adjacent discharge pipes are connected by a pipe.

[0006] As a further improvement, the connector includes an inner ring seat disposed inside the rupture section, and a plurality of connecting rods are connected to the side of the inner ring seat near the center of the rupture section. The ends of all the connecting rods are connected to a docking cylinder, and adjacent docking cylinders are connected by a docking shaft.

[0007] As a further improvement, the inner ring seat is also connected to a rear push rod at the rear end of the connecting rod, the end of the rear push rod extends to the docking cylinder, and a support plate is provided between the rear push rod and the connecting rod.

[0008] As a further improvement, the outer bonding frame includes a bonding plate connected to the gap between the two rupture sections, and sealing plates are provided on both sides of the bonding plate. The sealing plates are tightly attached to the outside of the rupture sections, and an outer wrapping section is provided on the outside of the sealing plates.

[0009] As a further improvement, the extension section is an annular plate fixedly connected to the bonding plate, and the annular plate has the same annular width as the rupture section.

[0010] As a further improvement, the bonding component is divided into two groups, which are respectively disposed on both sides of the extension section. Each group of bonding components includes an embedded section located between the extension section and the outer ring wall of the rupture section. The embedded section is connected to an inner bonding section on one side of the rupture section in the axial direction. The inner bonding section is tightly attached to the inner wall of the rupture section.

[0011] As a further improvement, the inner bonding section includes two side connecting sections bonded to the inner wall of the rupture section. The upper ends of the two side connecting sections are connected to a top connecting section, and the lower ends of the two side connecting sections are connected to a thin connecting section. The width of the thin connecting section is smaller than that of the side connecting sections.

[0012] As a further improvement, the outer auxiliary frame includes a mounting seat disposed inside the partition chamber, and each mounting seat is equipped with a pressure-applying component. The pressure-applying component is attached to the outside of the outer bonding frame by an arc plate, and the number of pressure-applying components in the area corresponding to the thin connecting section is greater than the number in the area corresponding to the side connecting section.

[0013] The beneficial effects of this utility model are: Existing technologies require a considerable amount of time to allow mid-section or rear-end exhaust gas to reach the front exhaust position. Furthermore, exhaust gas that cannot be discharged promptly at this position hinders heat dissipation, thus affecting the pyrolysis effect. Therefore, this invention addresses this by using a connecting gas-guiding structure to first divide the pyrolysis section into segments that can rotate synchronously. An external bonding frame, extension section, and bonding element are installed between the two pyrolysis sections to create a closed, movable seal, thus creating a near-oxygen-free environment for pyrolysis. The gas generated during pyrolysis can be discharged at any time through the exhaust pipe on the external bonding frame, allowing the gas to flow out from between the two pyrolysis sections immediately after generation, eliminating excessive flow time and achieving rapid gas discharge without affecting the flow of the internal heat source.

[0014] Although the two pyrolysis sections are set up in segments, it is not possible to set a driving structure on each pyrolysis section. Therefore, the pyrolysis sections still need to be in a linked state from beginning to end. Therefore, this utility model uses a connecting piece to form a linked frame with the inner ring seat on the inner wall of the pyrolysis section and the connecting rod. Then, the different frames are connected together by a docking shaft. Thus, when the first pyrolysis section rotates, it can drive the other pyrolysis sections to rotate. This achieves the effect of driving the rotation of multiple pyrolysis sections with only one set of driving structure, reducing the overall operating cost.

[0015] Compared to the very heavy fracture section, the overall connection strength may not be sufficient if only a connecting rod is used, and the fracture section may break during linkage. Therefore, this invention can thicken the connecting rod by setting a rear push rod and a support plate on the rear side of the inner ring seat, thereby increasing the diameter of the connecting rod, increasing its strength, and ensuring the linkage effect.

[0016] A tight, movable seal is required between the pyrolysis sections to create a sealed environment. In this invention, the outer sides of the pyrolysis sections are sealed by an outer bonding frame. The outer bonding frame adopts a three-section extension method, with the thickness gradually decreasing through the bonding plate, sealing plate, and outer wrapping section, thereby enhancing the cooperation effect with the pyrolysis sections.

[0017] Inside the pyrolysis section, an internal bonding surface is formed by bonding components to achieve an internal sealing effect. Combined with the sealing effect of the external bonding frame and the filling effect of the middle section of the extension section, a slight sealing effect between the pyrolysis sections is achieved, thereby creating an oxygen-free environment.

[0018] During the internal sealing process, the inner bonding section inevitably causes a bulge to appear inside the smooth fracture section, which blocks the powder from being transported forward. Therefore, this invention divides the inner bonding section into segments and makes the thin connecting section closest to the bottom thinner, so that the width of this position is narrowed and the powder can pass through this position more easily.

[0019] If the outer bonding frame is bound by its own tightening force, the sealing effect is limited. Therefore, this utility model also provides an outer auxiliary frame on the outer side of the outer bonding frame. The pressure member on the outer auxiliary frame can provide a certain support and assistance to the outer bonding frame, so that the bonding effect between it and the split section is better. Even if the bonding plate is thick, a tight bonding effect can be achieved. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] Reference Figures 1-6As shown, an anaerobic pyrolysis device includes a feeder 10 connected to a crushing mechanism. The feeder 10 is connected to a hollow rotating cylinder 20. A main drive unit 21 is connected to the lower end of the hollow rotating cylinder 20. The hollow rotating cylinder 20 is connected to a pyrolysis cylinder 22. A lower discharge cylinder 23 is connected to the discharge end of the pyrolysis cylinder 22. The lower discharge cylinder 23 is connected to a conveyor belt. The device also includes a connecting gas guiding structure 30. A partition chamber 3 is provided outside the pyrolysis cylinder 22. The pyrolysis cylinder 22 includes several pyrolysis sections 221. Two pyrolysis sections 221 are connected by a connector 222. When one pyrolysis section 221 rotates, the other pyrolysis section 221 is driven to rotate through the connector 222. The connecting gas guiding structure 30 includes an outer bonding frame 31 disposed inside the partition chamber 3. The outer bonding frame 31 is connected to the two pyrolysis sections 221. Between 1, the outer bonding frame 31 is connected to an extension section 32 on the side facing the pyrolysis section 221. An bonding member 33 is provided inside the extension section 32 facing the pyrolysis section 221. The bonding member 33 is tightly attached to the inner wall of the pyrolysis section 221. An outer auxiliary frame 34 is provided on the outer side of the outer bonding frame 31. A discharge pipe 35 is provided on the outer side of the outer bonding frame 31. Adjacent discharge pipes 35 are connected by pipes. The inner retention structure 40 includes two driving members 41 provided on the outer side of the outer bonding frame 31. A linkage member 42 is connected to the side of the driving member 41 facing the pyrolysis section 221. A blocking member 43 is provided at the bottom of the linkage member 42. Battery fragments transmitted through the pyrolysis cylinder 22 are blocked by the blocking member 43 and pyrolyzed at that point. After a period of time, the driving member 41 drives the blocking member 43 to flip and throw the battery fragments to the rear end via the linkage member 42.

[0031] In existing technologies, waiting for the mid-section or rear-end exhaust gas to reach the front exhaust position requires a long time. Furthermore, exhaust gas that cannot be discharged in time at this position will hinder the heat source from dissipating to that position, thus affecting the pyrolysis effect. Therefore, in this embodiment, the connecting gas guiding structure 30 is set to first divide the pyrolysis section 221 into segments, but these segments can rotate synchronously. At the same time, an outer bonding frame 31, an extension section 32, and a bonding element 33 are set between the two pyrolysis sections 221 to seal them, thereby achieving a movable sealing effect. This creates a near-oxygen-free environment for pyrolysis, and the gas generated during the pyrolysis process can be discharged at any time through the discharge pipe 35 on the outer bonding frame 31. This allows the gas to flow out from the position between the two pyrolysis sections 221 as soon as it is generated, without requiring excessive flow time, thus achieving rapid gas discharge without affecting the flow of the internal heat source.

[0032] Although the two fracture sections 221 are segmented, it is not possible to set a driving structure on each fracture section 221. Therefore, the fracture sections 221 still need to be in a linked state from beginning to end. Specifically, the connector 222 in this embodiment includes an inner ring seat 2221 disposed inside the fracture section 221. Several connecting rods 2222 are connected to the side of the inner ring seat 2221 near the center of the fracture section 221. The ends of all the connecting rods 2222 are connected to a docking cylinder 2223. Adjacent docking cylinders 2223 are connected by a docking shaft 2224. Through the connector 222, the inner ring seat 2221 and the connecting rods 2222 on the inner wall of the fracture section 221 form a linked frame. The different frames are then connected together by the docking shaft 2224. Thus, the rotation of the first fracture section 221 can drive the rotation of the other fracture sections 221. This achieves the effect of driving the rotation of multiple fracture sections 221 with only one set of driving structures, reducing the overall operating cost.

[0033] Compared to the very heavy fracture section 221, the overall connection strength may not be sufficient if it is only connected by the connecting rod 2222. The fracture section 221 may break during linkage. Therefore, in this embodiment, the inner ring seat 2221 is also connected to a rear push rod 2225 at the rear end of the connecting rod 2222. The end of the rear push rod 2225 extends to the docking cylinder 2223. A support plate 2226 is provided between the rear push rod 2225 and the connecting rod 2222. By providing the rear push rod 2225 and the support plate 2226 on the rear side of the inner ring seat 2221, the connecting rod 2222 can be thickened, thereby increasing the diameter of the connecting rod 2222 and increasing its strength, thus ensuring the linkage effect.

[0034] A tight, movable seal is required between the rupture segments 221 to create a sealed environment. In this embodiment, the outer bonding frame 31 includes a bonding plate 311 connected to the gap between the two rupture segments 221. Sealing plates 312 are provided on both sides of the bonding plate 311. The sealing plates 312 are tightly attached to the outside of the rupture segments 221. An outer wrapping section 313 is provided on the outside of the sealing plates 312. The rupture segments 221 and their outer sides are sealed by the outer bonding frame 31. The outer bonding frame 31 adopts a three-section extension method, with the thickness gradually decreasing through the bonding plate 311, the sealing plate 312, and the outer wrapping section 313, thereby enhancing the cooperation effect with the rupture segments 221.

[0035] Inside the fracture section 221, internal bonding is achieved through bonding members 33. Specifically, there are two sets of bonding members 33, respectively located on both sides of the extension section 32. Each set of bonding members 33 includes an embedded section 331 located between the extension section 32 and the outer annular wall of the fracture section 221. The embedded section 331 is connected to an inner bonding section 332 on one side of the fracture section 221 along the axial direction. The inner bonding section 332 is tightly attached to the inner wall of the fracture section 221, forming an inner bonding surface inside the fracture section 221, thereby achieving an internal sealing effect. Since the extension section 32 is an annular plate fixed to the bonding plate 311, and the annular width of the annular plate is the same as the annular width of the fracture section 221, combined with the sealing effect of the outer bonding frame 31 and the filling effect of the middle section of the extension section 32, a slight sealing effect between the fracture sections 221 is achieved, thereby creating an oxygen-free environment.

[0036] During the internal sealing process, the inner bonding section 332 inevitably causes a protrusion inside the smooth fracture section 221, which blocks the powder from being transported forward. Therefore, in this embodiment, the inner bonding section 332 includes two side connecting sections 3321 that are bonded to the inner wall of the fracture section 221. The upper ends of the two side connecting sections 3321 are connected to a top connecting section 3322, and the lower ends of the two side connecting sections 3321 are connected to a thin connecting section 3323. The width of the thin connecting section 3323 is smaller than that of the side connecting sections 3321. By segmenting the inner bonding section 332 and making the thin connecting section 3323 closest to the bottom thinner, the width at that position is narrowed, and the powder can pass through that position more easily.

[0037] On the outside of the outer bonding frame 31, if it is bound by its own tightening force, the sealing effect is limited. Therefore, the outer auxiliary frame 34 in this embodiment includes a mounting seat 341 disposed inside the partition chamber 3. Each mounting seat 341 is equipped with a pressure member 342. The pressure member 342 is attached to the outside of the outer bonding frame 31 by an arc plate 343. The number of pressure members 342 in the area corresponding to the thin connecting section 3323 is greater than the number in the area corresponding to the side connecting section 3321. By setting the outer auxiliary frame 34 on the outside of the outer bonding frame 31, the pressure members 342 on the outer auxiliary frame 34 can form a certain support and assistance effect on the outer bonding frame 31, so that the bonding effect between it and the split section 221 is better. Even if the bonding plate 311 is thick, a tight bonding effect can be achieved.

[0038] Between the two pyrolysis sections 221, there is often a certain temperature difference. The temperature difference may not be very obvious, but due to the distance from the heat source, there will be a difference of tens of degrees. In order to improve the retention effect of powder in each pyrolysis section 221, this utility model sets an internal retention structure 40 on each outer bonding frame 31. The rotation of the driving component 41 can drive the blocking component 43 to swing periodically, blocking the powder and pushing it upward. After a period of stagnation, the powder is thrown to the rear end, so that the powder can be uniformly heated and pyrolyzed in each pyrolysis section 221, promoting the pyrolysis process.

[0039] During the rotation of the linkage 42 and the blocking member 43, since the blocking member 43 needs to convey material, the linkage 42 cannot directly penetrate the blocking member 43. Therefore, the linkage 42 in this embodiment includes two hanging rods 421 that are inserted into the outer fitting frame 31. One end of the hanging rod 421 is connected to the drive member 41, and the other ends of the two hanging rods 421 are connected through a U-shaped member 422. The blocking member 43 is a concave arc-shaped bucket. The blocking member 43 is made into an arc-shaped scoop, and the linkage 42 is made into a U-shaped member 422 that bypasses the scoop, thereby forming a supported clearance and fully achieving the effect of blocking the powder.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
