Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, specifically to a multi-stage cooling and electrified crushing device. Background Technology

[0002] my country is the country with the fastest electrification process and a major producer and seller of new energy vehicles. Pouch batteries are the third generation of power batteries developed from the original steel-cased, aluminum-cased, and plastic-cased batteries. Pouch lithium batteries use aluminum-plastic film packaging in their outer shell structure. Due to their advantages such as light weight, high space utilization efficiency, good heat dissipation, and high safety, they are widely used in new energy vehicles, solar photovoltaic power generation, portable power supplies, and other industries. With the widespread use of pouch batteries, it is necessary to recycle them after they fail and are disposed of, as they contain abundant elements such as nickel, cobalt, manganese, lithium, copper, and aluminum.

[0003] In the practice of recycling and processing used soft-pack lithium-ion batteries, a critical problem that urgently needs to be solved and cannot be ignored has gradually emerged: these used batteries are often not completely depleted, but rather carry a certain amount of charge. This characteristic brings great safety hazards and complex challenges to the subsequent mechanical crushing and recycling process. In the normal mechanical crushing and recycling process, the crushing step, which should be carried out in an orderly manner, becomes fraught with danger due to the fact that the battery is charged. When used soft-pack lithium-ion batteries are put into the crushing equipment, under the violent mechanical action, the positive and negative electrode plates inside the battery are crushed into fine fragments. These fragments tumble and collide continuously in the crushing chamber. Due to the randomness and uncontrollability of the crushing process, the fragments of the positive and negative electrode plates are very prone to breakage. When the positive and negative electrode fragments are stacked, it's like building a low-impedance conductive path in a circuit, instantly creating a local short circuit. The consequences of such a short circuit are unimaginable. The electrolyte, a crucial medium for storing and transmitting energy in lithium-ion batteries, contains a large amount of energy. Under the intense effect of a local short circuit, this energy is released at an extremely rapid rate. According to the law of conservation of energy, this rapidly released energy is converted into a large amount of heat, causing the temperature inside the crushing chamber to rise sharply in a short time. This high-temperature environment not only accelerates the decomposition and volatilization of the electrolyte, producing large amounts of toxic and harmful gases such as hydrogen fluoride and volatile organic compounds, but also poses a serious threat to the health of operators.

[0004] Therefore, this utility model provides a multi-stage cooling and electrified crushing device to solve the above problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a multi-stage cooling electrostatic crushing device to solve the problem that the large amount of heat generated by the release of a large amount of energy in the electrolyte poses a risk of combustion and explosion, hindering safe production and endangering people's lives.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A multi-stage cooling and electrified crushing device includes a conveyor platform for conveying materials. The conveyor platform is equipped with a primary cooling component and a secondary cooling component. The primary cooling component consists of a fan, which can send outside air into the interior of the primary cooling component to cool the materials. The secondary cooling component consists of a refrigeration device, which works in conjunction with the primary cooling component to reduce the temperature of the materials.

[0008] The discharge end of the conveyor is equipped with a primary crushing assembly, which includes a first crushing box installed at the discharge end of the conveyor. The inner wall of the first crushing box is fixed with two symmetrical first guide plates, and there is a material dropping area between the two first guide plates. The material discharged from the discharge end of the conveyor can fall into the interior of the first crushing box for crushing through the material dropping area. The interior of the first crushing box is rotatably connected with two symmetrical first crushing shafts, which are used to crush the material.

[0009] Preferably, a secondary crushing assembly is installed at the bottom of the first crushing box. The secondary crushing assembly includes a second crushing box installed at the bottom of the first crushing box. A second guide plate is fixed on the inner wall of the second crushing box to guide the material into the second crushing box for crushing. A second crushing shaft is installed inside the second crushing box, and a second drive source is installed outside the second crushing box. The output end of the second drive source is connected to the second crushing shaft to drive the second crushing shaft to rotate and crush the material again.

[0010] Preferably, a three-stage crushing assembly is installed on the second crushing box. The three-stage crushing assembly includes two sliding frames symmetrically arranged inside the second crushing box. The sliding frames have multiple equidistant accommodating cavities inside. Each accommodating cavity has a sliding plate slidably connected to its inner wall. A first sleeve is provided on one side of the sliding plate, and a circular plate is fixed to the other end of the first sleeve. A first conical head is fixed to one side of the circular plate for crushing materials.

[0011] Preferably, the first sleeve is provided with a second sleeve inside, and the inner wall of the first sleeve is slidably connected to the outer wall of the second sleeve. A second circular hole adapted to the second sleeve is provided on the sliding frame, and the outer wall of the second sleeve is fixed to the inner wall of the second circular hole. A first connecting post is slidably connected inside the second sleeve. A third circular hole adapted to the first connecting post is provided on the circular plate, and the outer wall of the first connecting post is rotatably connected to the inner wall of the third circular hole.

[0012] Preferably, the first conical head has a receiving opening, and the inside of the receiving opening is provided with a compression block for crushing and compressing the material.

[0013] Preferably, a first arc-shaped block is fixed to one end of the extrusion block inside the first conical head, and a second arc-shaped block is fixed to the outer wall of the first connecting column.

[0014] Preferably, the outer wall of the first connecting column is fixed with a protrusion, and the inner wall of the second sleeve is provided with a spiral groove, and the protrusion is slidably connected inside the spiral groove.

[0015] Preferably, the upper side of the sliding frame is provided with two threaded rods, which are symmetrically arranged inside the second crushing box. Each threaded rod has two threaded ends, and each threaded end of the threaded rod is threadedly connected to a sliding block. A horizontal plate is installed between two adjacent sliding blocks, and the top of the sliding plate is fixed to the bottom of the corresponding horizontal plate.

[0016] Preferably, a transmission belt is installed between the threaded rods, a second drive source is installed outside the second crushing box, and the output end of the second drive source is fixed to one end of the threaded rod.

[0017] Preferably, the sliding plate has a first circular hole that matches the first sleeve, and the outer wall of the first sleeve is fixed to the inner wall of the first circular hole. The sliding frame has a receiving hole, and the first sleeve is slidably connected inside the receiving hole.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. The conveyor platform is equipped with a primary cooling device and a secondary cooling device. The primary cooling device uses a fan design to draw in external air and create an airflow at a certain speed, which directly acts on the material on the conveyor platform to achieve a preliminary cooling effect. The secondary cooling device uses a refrigeration device to emit cold air and provide a more powerful low-temperature environment for the material. This dual cooling mechanism improves the cooling effect on the material.

[0020] 2. Two internally fixed, symmetrical first guide plates form a material dropping area, allowing the material discharged from the conveyor's outlet to fall smoothly into the first crushing box. The two symmetrical first crushing shafts rotate at high speed under the drive of the first drive source, using their surface crushing teeth or blades to strongly impact and shear the material, achieving primary crushing of the material and initially refining larger pieces of material into smaller particles. This primary crushing method can quickly process large quantities of material and improve overall processing efficiency.

[0021] 3. The secondary crushing assembly receives the material after primary crushing and performs further crushing. The second guide plate fixed to the inner wall of the second crushing box can effectively guide the material falling from the first crushing box, ensuring that the material enters the second crushing box accurately for crushing. The second crushing shaft rotates under the drive of the second drive source, and its crushing capacity is stronger than that of the primary crushing shaft. It can further crush the material after primary crushing, further refine the material, and make the crushing of the material more uniform.

[0022] 4. Two symmetrically arranged sliding frames inside the second crushing box provide a stable motion frame for the entire three-stage crushing process. Multiple equally spaced receiving cavities inside the sliding frames, as well as sliding plates slidably connected within the receiving cavities, constitute the crushing unit. The sliding connection design of the first sleeve and the second sleeve allows the first conical head to move to a certain extent in the vertical direction, thereby squeezing and crushing the material.

[0023] 5. When the third drive source rotates, the two threaded rods rotate synchronously via the transmission belt. The sliding blocks on the threaded rods move closer or further apart under the action of the threads, thereby driving the horizontal plate and the sliding plate to move, bringing the two sliding frames closer together. At this time, the first conical head applies pressure to the material above the second crushing shaft for initial crushing. Simultaneously, during the sliding process of the sliding plate, the first connecting column moves inside the second sleeve, and the protrusions on its outer wall slide along the trajectory of the spiral groove. Due to the special shape of the spiral groove, the first connecting column rotates during the movement. Through the cooperation of the first arc-shaped block and the second arc-shaped block, the first connecting column pushes the extrusion block to slide out of the receiving port, applying additional extrusion force to the material and further increasing the degree of crushing of the material.

[0034] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0035] As attached Figures 1-5 As shown, a multi-stage cooling and electrified crushing device includes a conveyor platform 10 for conveying materials. The conveyor platform 10 is equipped with a primary cooling component 11 and a secondary cooling component 12.

[0036] The discharge end of the conveyor 10 is equipped with a primary crushing component 20 for primary crushing of materials.

[0037] The primary crushing assembly 20 includes a first crushing box 21 installed at the discharge end of the conveyor 10. The first crushing box 21 has a through-cavity. Two symmetrical first guide plates 22 are fixed to the inner wall of the first crushing box 21. There is a material dropping area between the two first guide plates 22. The material discharged from the discharge end of the conveyor 10 can fall into the interior of the first crushing box 21 through the material dropping area for crushing. Two symmetrical first crushing shafts 23 are rotatably connected inside the first crushing box 21. The two first crushing shafts 23 are used to crush the material. A first drive source 24 is installed on the first crushing box 21, and the output end of the first drive source 24 is connected to the first crushing shafts 23 to drive the first crushing shafts 23 to rotate and crush the material.

[0039] The secondary crushing assembly 30 includes a second crushing box 31 installed at the bottom of the first crushing box 21.

A second drive source is installed outside the second crushing box 31, and the output end of the second drive source is connected to the second crushing shaft 33 to drive the second crushing shaft 33 to rotate and crush the material again.

[0040] The second crushing box 31 is equipped with a three-stage crushing assembly 40, which is used to increase the degree of crushing of materials.

[0041] The three-stage crushing assembly 40 includes two symmetrically arranged sliding frames 41 inside the second crushing box 31. The interior of each sliding frame 41 has multiple equidistantly arranged receiving cavities 42. The inner wall of each receiving cavity 42 is slidably connected to a sliding plate 43. A first sleeve 44 is provided on one side of the sliding plate 43. A first circular hole 45 adapted to the first sleeve 44 is opened on the sliding plate 43, and the outer wall of the first sleeve 44 is fixed to the inner wall of the first circular hole 45. The sliding frame 41 has a receiving hole, and the first sleeve 44 is slidably connected inside the receiving hole. A circular plate 46 is fixed to the other end of the first sleeve 44. A first conical head 47 is fixed to one side of the circular plate 46 for crushing materials.

[0042] The first sleeve 44 has a second sleeve 48 inside, and the inner wall of the first sleeve 44 is slidably connected to the outer wall of the second sleeve 48. The sliding frame 41 has a second round hole 49 that matches the second sleeve 48, and the outer wall of the second sleeve 48 is fixed to the inner wall of the second round hole 49. The second sleeve 48 has a first connecting post 410 slidably connected inside, and the circular plate 46 has a third round hole 411 that matches the first connecting post 410, and the outer wall of the first connecting post 410 is rotatably connected to the inner wall of the third round hole 411.

[0043] The first conical head 47 has an opening for receiving, and an extrusion block 412 is provided inside the opening for extruding and crushing materials. One end of the extrusion block 412 located inside the first conical head 47 is fixed with a first arc-shaped block 413, and a second arc-shaped block 414 is fixed to the outer wall of the first connecting column 410.

[0044] The outer wall of the first connecting post 410 is fixed with a protrusion 415, and the inner wall of the second sleeve 48 is provided with a spiral groove 416, and the protrusion 415 is slidably connected inside the spiral groove 416.

[0045] Two threaded rods 417 are provided on the upper side of the sliding frame 41. The two threaded rods 417 are symmetrically arranged inside the second crushing box 31. Each threaded rod 417 has two threaded ends, and each threaded end of the threaded rod 417 is threadedly connected to a sliding block 418. A horizontal plate 421 is installed between two adjacent sliding blocks 418, and the top of the sliding plate 43 is fixed to the bottom of the corresponding horizontal plate 421.

A second drive source 420 is installed outside the second crushing box 31, and the output end of the second drive source 420 is fixed to one end of the threaded rod 417.

[0046] In use, the material is placed on the conveyor table 10, and the conveyor belt on the conveyor table 10 is driven by the drive source to roll, thereby conveying the material. When the material passes through the first cooling unit 11 and the second cooling unit 12, it will be cooled first. The cooled material will fall into the first crushing box 21 and undergo primary crushing, or coarse crushing, by the first crushing shaft 23. Then, the coarsely crushed material falls into the second crushing box 31. Since the first conical head 47 is located above the second crushing shaft 33, as the second drive source 420 rotates, the two threaded rods 417 rotate synchronously, and the two sliding frames 41 move closer to each other. The sliding frames 41 drive the first conical head 47 to crush the material above the second crushing shaft 33 through the sliding plate 43 and the first sleeve 44. The material is crushed by compression. During the sliding process of the sliding plate 43, the first connecting column 410 moves inside the second sleeve 48, and the protrusion 415 slides along the trajectory of the spiral groove 416. At this time, the first connecting column 410 will rotate due to the cooperation of the protrusion 415 and the spiral groove 416. Since the arc surface of the second arc block 414 is slidably connected to the arc surface of the first arc block 413, the first connecting column 410 will push the extrusion block 412 out of the receiving port through the cooperation of the first arc block 413 and the second arc block 414, thereby applying extrusion pressure to the material and increasing the degree of crushing of the material. The second drive source drives the second crushing shaft 33 to rotate through the output end, and then crushes the material crushed by the first cone head 47 again, thereby improving the degree of crushing of the material.

[0047] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
