Description

Technical Field

[0001] The present invention belongs to the technical field of dry distillation of solid carbonaceous materials, and in particular relates to high-temperature pyrolysis equipment and a pyrolysis process for power batteries. Background Art

[0002] Battery pyrolysis is the process of heat treatment of harmful substances such as sulfides and nitrogen-containing compounds in the battery, so that the harmful substances can be fully separated to facilitate the subsequent crushing and disassembly of the battery, thereby recovering the reusable parts of the battery.

[0003] In related technologies, most pyrolysis cells work through rotary kilns. After a screw feeder transports the material to one end of the rotary kiln, the material accumulated at one end of the rotary kiln is evenly spread on the bottom wall of the rotary kiln through a material discharge and leveling device. At the same time, when the rotary kiln rotates, the material discharge and leveling device blocks the discharge port of the rotary kiln to prevent the material from falling from the discharge port during rotation.

[0004] However, the existing blanking and paving assembly has an outer wall that abuts against the inner bottom of the rotary kiln, which causes wear when the rotary kiln rotates. When the material in the rotary kiln is blanked, the outer wall of the blanking and paving assembly needs to abut against the inner wall of the rotary kiln.

[0005] Therefore, how to reduce the friction between the blanking and paving assembly and the inner wall of the rotary kiln, and how to avoid material residue on the inner wall of the rotary kiln during blanking are technical problems that need to be solved urgently in this field.

[0006] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0067] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them.

In addition, in the drawings, the thickness of components may be exaggerated or reduced in order to effectively describe technical content.

[0069] Herein, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." when following a list of elements modify the entire list of elements, rather than modifying individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0070] The terms used herein are only used to describe specific exemplary configurations and are not intended to be limiting. As used herein, the singular articles "a", "an" and "the" may also be intended to include plural forms, unless otherwise clearly indicated herein.

[0071] As used herein, the phrases "in one embodiment," "according to one embodiment," "in some embodiments," and the like generally refer to the fact that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure.

[0072] After research, it was found that the shortcomings of the existing technology are: in the relevant technology, most of the pyrolysis cells are operated through a rotary kiln. After the screw feeder transports the material to one end of the rotary kiln, the material accumulated at one end of the rotary kiln is evenly spread on the bottom wall of the rotary kiln through the material discharge and leveling device. At the same time, when the rotary kiln rotates, the material discharge and leveling device blocks the discharge port of the rotary kiln to prevent the material from falling from the discharge port during rotation.

[0073] However, the existing material leveling device has an outer wall that abuts against the inner bottom of the rotary kiln, which causes wear when the rotary kiln rotates. When the material in the rotary kiln is unloaded, the outer wall of the material leveling device needs to abut against the inner wall of the rotary kiln.

[0074] Therefore, how to reduce the friction between the material unloading and leveling device and the inner wall of the rotary kiln, and how to prevent the material from remaining on the inner wall of the rotary kiln during unloading are technical problems that need to be solved urgently in this field.

[0075] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0076] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0077] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0078] like Figures 1 to 6As shown, some embodiments provide a high-temperature pyrolysis device for power batteries, comprising: a furnace body 1, which is cylindrical and has an axis parallel to the horizontal plane; it is rotatably arranged in a heating seat 5; the interior of the furnace body 1 is hollow and arranged horizontally, and a transmission gear disc 10 is fixed on the outer wall of the furnace body 1; a plurality of heating tubes are arranged in the heating seat 5, and the heating tubes are arranged circumferentially around the furnace body 1, and the heating tubes are suitable for heating the material in the furnace body 1. The material described in this embodiment is a granular material after battery crushing. A second drive motor 11 is provided at one end of the heating seat 5, and the transmission gear disc 10 is transmission-connected to the second drive motor 11. The second drive motor 11 is suitable for driving the furnace body 1 to rotate, and the circumferential rotation of the furnace body 1 can evenly heat the material inside the furnace body 1. The tailstock 3 is arranged at one end of the furnace body 1 away from the feeding unit 2, and the interior of the tailstock 3 is hollow; a lower feeding port 30 is opened at the lower part of the tailstock 3, and the unloading and leveling component 4 moves horizontally outward along the inner wall of the furnace body 1, suitable for pushing the material in the furnace body 1 toward the lower feeding port 30. A feeding unit 2 is provided at one end of the furnace body 1 and is suitable for conveying materials into the furnace body 1; a tailstock 3 is provided in the unloading section of the furnace body 1; a unloading and leveling component 4 is slidably provided in the furnace body 1 and passes through the tailstock 3; wherein, the material is accumulated at a position of the furnace body 1 close to the feeding unit 2, and the unloading and leveling component 4 moves spirally to abut against the feeding unit 2; the scraping member 40 of the unloading and leveling component turns to the inner top wall of the furnace body 1, and the unloading and leveling component moves outward to level the accumulated material on the inner bottom wall of the furnace body 1; when unloading, the unloading and leveling component is rotated so that the scraping member 40 abuts against the inner bottom wall of the furnace body 1, and the unloading and leveling component slides outward to pull the material to be unloaded. Through the setting of the material unloading and leveling component 4, when the material is accumulated in the furnace body 1, the limiting cylinder 41 drives the positioning block 42 to move spirally into the furnace body 1 until the positioning block 42 abuts against the feeding unit 2, and the limiting cylinder 41 drives the positioning block 42 to move outward to pull the material so that it is evenly spread on the inner bottom wall of the furnace body 1; and when unloading is required, the scraper 40 is pushed to abut against the inner wall of the furnace body 1. At this time, the positioning block 42 rotates to the inner bottom wall close to the furnace body 1, and the scraper 40 moves outward to scrape off the material on the inner wall of the furnace body 1, and the scraper 40 can scrape off the residual material on the inner bottom wall of the furnace body 1, thereby improving the unloading speed.

[0079] Reference Attachment Figure 3The material laying assembly includes: a limiting cylinder 41, which is hollow and parallel to the furnace body 1; the limiting cylinder 41 passes through the tailstock 3 and is suitable for horizontal movement and rotation relative to the tailstock 3. A positioning block 42 is provided at the inner end of the limiting cylinder 41, with a gap between the outer wall of the positioning block 42 and the inner wall of the furnace body 1; the positioning block 42 is arc-shaped. When the furnace body 1 rotates circumferentially to heat the material inside, a gap is provided between the outer wall of the positioning block 42 and the inner wall of the furnace body 1. That is, when the furnace body 1 rotates, the positioning block 42 will not rub against the inner wall of the furnace body 1. The scraper 40 is in an arc shape and is slidably arranged on the side wall of the positioning block 42 and is suitable for contacting the inner wall of the furnace body 1; the adjustment rod 43 is slidably arranged in the limiting cylinder 41 and is linked to the scraper 40; wherein, when the feeding unit 2 conveys the material into the furnace body 1, since the furnace body 1 is horizontally arranged, the material entering the furnace body 1 will not automatically be flattened on the inner bottom wall of the furnace body 1, and the material will mostly accumulate in the furnace body 1 near the feeding unit 2. For details, please refer to the attached Figure 6 At this time, the positioning block 42 moves spirally to the leftmost side of the material in the furnace body 1, and the limiting cylinder 41 is rotated so that the positioning block 42 rotates to be above the material. At this time, the positioning block 42 is closest to the inner top wall of the furnace body 1; the limiting cylinder 41 moves in the direction away from the feeding unit 2, and the limiting cylinder 41 drives the positioning block 42 to move outward synchronously. The positioning block 42 is suitable for pushing the material in the furnace body 1 so that it is evenly spread on the inner bottom wall of the furnace body 1. The furnace body 1 rotates circumferentially to heat the material inside. When the furnace body 1 heats the material, the positioning block 42 is located in the furnace body 1 near the tailstock 3, and the positioning block 42 is in the position that best solves the inner bottom wall of the furnace body 1. At this time, the positioning block 42 is suitable for blocking the material to prevent part of the material from falling to the tailstock 3 when the furnace body 1 rotates.

[0080] When the material is heated and needs to be discharged, the limiting cylinder 41 drives the positioning block 42 to rotate circumferentially until the positioning block 42 is located above the material. In this state, the positioning block 42 is closest to the inner top wall of the furnace body 1. The limiting cylinder 41 pushes the positioning block 42 to move toward the feeding unit 2 until the side wall of the positioning block 42 abuts against the feeding unit 2. The positioning block 42 is rotated to make it closest to the inner bottom wall of the furnace body 1. The adjusting rod 43 moves inward to push the scraper 40 to slide toward the inner wall of the furnace body 1 until it abuts. The limiting cylinder 41 drives the positioning block 42 to move outward. The scraper 40 slides outward to scrape the material remaining on the inner bottom wall of the furnace body 1. The inward or outward movement of the limiting cylinder 41 in this embodiment can be achieved manually or by setting a driving device. Synchronously, the rotation of the limiting cylinder 41 can also be driven by the driving device.

[0081] Reference Attachment Figure 4, a limit block 44 is provided on the side of the positioning block 42 close to the feeding unit 2, the horizontal height of the limit block 44 is smaller than that of the positioning block 42, and the scraper 40 passes through the limit block 44; a gap is provided between the limit block 44 and the positioning block 42, and the scraper 40 is slidably provided in the gap. Among them, when the positioning block 42 abuts against the end wall of the feeding unit 2 and is close to the inner top wall of the furnace body 1, the limit block 44 is located above the feeding unit 2; the adjusting rod 43 moves inward to make the scraper 40 impact and vibrate the feeding unit 2. The adjusting rod 43 moves back and forth, which is suitable for driving the scraper 40 to intermittently impact the outer wall of the barrel 21, and the outer wall of the barrel 21 is impacted and vibrated, and the material remaining on the screw rod 24 will fall to the furnace body 1, avoiding the material remaining on the screw rod 24 and the inner wall of the barrel 21.

[0082] Furthermore, in order to allow the scraper 40 to retract into the gap between the positioning block 42 and the limiting block 44, a tension spring 420 is provided between the positioning block 42 and the scraper 40. The tension spring 420 is adapted to pull the scraper 40 so as to retract it into the gap between the positioning block 42 and the limiting block 44. When the scraper 40 is not pushed by the adjustment rod 43, the tension spring 420 pulls it inward and retracts it into the gap between the positioning block 42 and the limiting block 44.

[0083] Reference Attachment Figure 4 The end of the adjustment rod 43 is provided with a sloped surface 45; the side wall of the scraper 40 is provided with an inclined groove 46 that matches the sloped surface 45. When the adjustment rod 43 moves toward the feed unit 2, the inclined surface 45 is adapted to be inserted into the inclined groove 46, and the adjustment rod 43 is adapted to push the scraper 40 toward the inner wall of the furnace body 1, so that the outer wall of the scraper 40 abuts the inner wall of the furnace body 1. At this time, the positioning block 42 moves outward along the inner bottom wall of the furnace body 1, pushing the material in the furnace body 1 outward, while the scraper 40 scrapes away the material remaining on the inner bottom wall of the furnace body 1.

[0084] Reference Attachment Figure 2 The feeding unit 2 includes: a barrel 21, which is hollow inside and has one end inserted into the furnace body 1; a retaining ring is provided between the outer wall of the barrel 21 and the end wall of the furnace body 1, the retaining ring being fixed to the end wall of the furnace body 1 and being adapted to rotate circumferentially relative to the barrel 21; a hopper 22, which is provided at the upper end of the barrel 21 and is adapted to convey material into the barrel 21; a first drive motor, which is provided at the end of the barrel 21 away from the furnace body 1; and a screw 24, which is rotatably provided within the barrel 21 and is in transmission connection with the first drive motor.

[0091] The limiting cylinder 41 pushes the positioning block 42 to move spirally into the furnace body 1 until the positioning block 42 approaches the inner top wall of the furnace body 1. The positioning block 42 then moves outward to pull the material so that it is evenly spread on the inner bottom wall of the furnace body 1.

[0092] The scraper 40 is pushed to slide toward the inner bottom wall of the furnace body 1 until it abuts against the inner bottom wall. The scraper 40 slides outward to scrape off the material remaining on the inner bottom wall of the furnace body 1 .
