Description

Technical Field

[0001] This utility model relates to the technical field of material conveying devices, specifically to a material conveying device for the pyrolysis of waste lithium iron phosphate batteries. Background Technology

[0002] The lithium iron phosphate recycling system uses waste lithium iron phosphate cells as raw materials. Pre-treatment processes include brine discharge, coarse crushing, pyrolysis, fine crushing, magnetic separation, and sorting to obtain lithium iron phosphate powder, as well as copper, iron, and aluminum powder. After acid dissolution, two-stage impurity removal, and lithium precipitation, crude lithium carbonate is obtained (entering the lithium salt system). The calcium phosphate filter cake from the first-stage impurity removal process is dried to obtain sodium phosphate product. The lithium-precipitated liquid then enters the sodium sulfate system. During pyrolysis, the coarsely crushed powder is directly conveyed through a sealed silo to an electrically heated pyrolysis furnace for pyrolysis (intermittent feeding, heating time 3-6 hours), generating pyrolysis flue gas G2-2 containing HF, CO2, P2O5, CH4, H2, and combustible organic gases, and waste tar S2-1.

[0003] However, during the material conveying process, it was found that the gas inside the pyrolysis furnace would enter the silo. When materials need to be fed into the pyrolysis furnace, harmful gases inside the furnace would leak out, causing air pollution and endangering the health of workers, posing a significant safety hazard. Therefore, a material conveying device for the pyrolysis of waste lithium iron phosphate batteries is needed to solve the above problems. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a conveying device for the pyrolysis of waste lithium iron phosphate batteries, including a ball cylinder 1. A feed pipe 101 is fixedly connected to the left end of the ball cylinder 1, and a discharge pipe 102 is fixedly connected to the right end of the ball cylinder 1. The feed pipe 101 and the discharge pipe 102 are inclined together. A ball 103 is disposed inside the ball cylinder 1. A cylindrical groove is formed on the side end of the ball 103. A dispersing plate 104 is fixedly connected to the inner wall of the cylindrical groove. The side end of the dispersing plate 104 has several holes large enough for materials of normal size to pass through. A connecting assembly 2 for installing equipment is fixedly connected to the top of the ball cylinder 1. A connection is provided between the top of the connecting assembly 2 and the top of the ball 103 for... The rotating assembly 3 drives the ball 103 to rotate. The side end of the connecting assembly 2 is provided with a striking assembly 4 for striking the ball cylinder 1 and the ball 103 to assist in dispersing materials. The device is equipped with various components through the connecting assembly 2. The rotating assembly 3 drives the ball 103 in the ball cylinder 1 to rotate. When the cylindrical groove is aligned with the feed pipe 101, the material enters the groove. The closed end of the ball 103 fits against the ball cylinder 1 to form a sealed space to prevent harmful gases from the pyrolysis furnace from leaking out. After feeding, the ball 103 rotates to the cylindrical groove and aligns with the discharge pipe 102. At the same time, the striking assembly 4 is activated to strike the ball cylinder 1. With the inclined structure and the aperture of the dispersion plate 104, it not only assists in feeding materials and breaking up agglomerates, but also blocks gas leakage throughout the process, ensuring safety and material conveying effect.

[0021] As one implementation method in this embodiment, such as Figure 3 and Figure 4As shown, the connecting component 2 includes a base 201, which is fixedly connected to the top of the ball tube 1. A bracket 202 is fixedly connected to the side end of the base 201, and a side frame 203 is fixedly connected to the side end of the bracket 202. An arc-shaped groove 204 is provided at the top of the base 201. The side frame 203 is L-shaped. A pressable button 306 is installed at the bottom of the arc-shaped groove 204. The bracket 202 is designed to facilitate the installation of the rotating component 3, and the side frame 203 is designed to facilitate the installation of the striking component 4.

[0022] As one implementation method in this embodiment, such as Figure 1 and Figure 4 As shown, the rotating assembly 3 includes a motor 301, which is fixedly mounted on the top of the bracket 202. A rotating rod 302 is mounted on the output end of the motor 301. The bottom end of the rotating rod 302 is rotatably positioned between the base 201 and the ball cylinder 1. The bottom end of the rotating rod 302 is fixedly connected to the top of the ball 103. A sleeve plate 303 is fixedly connected to the outer end of the rotating rod 302. An extension plate 304 is fixedly connected to the side end of the sleeve plate 303. A limit rod 305 is fixedly connected to the bottom end of the extension plate 304. The limit rod 305 is inserted into the arc-shaped groove 204. In operation, the motor 301 starts... The motor drives the rotating rod 302 to rotate, and the ball 103 fixed at the bottom of the rotating rod 302 rotates inside the ball cylinder 1. When the cylindrical groove on the side of the ball 103 is aligned with the left feed pipe 101, the motor 301 stops. At this time, the dispersion plate 104 on the inner wall of the cylindrical groove is directly opposite the feed inlet, and the material can enter the cylindrical groove through the feed pipe 101. The closed end of the ball 103 without groove is attached to the inner wall of the ball cylinder 1. Together with the inclined feed pipe 101 to discharge pipe 102 structure, a sealed space is formed, which completely blocks the harmful gas in the pyrolysis furnace from entering the silo in reverse or leaking out, avoiding air pollution and personnel health risks.

[0023] As one implementation method in this embodiment, such as Figure 4As shown, the striking assembly 4 includes a second motor 401, which is fixedly installed inside the side frame 203. A second rotating rod 402 is installed at the output end of the second motor 401. A rotating plate 403 is fixedly connected to the side end of the rotating rod 402. An elastic steel plate 404 is fixedly connected to the side end of the rotating plate 403. An inclined striking head 405 is fixedly connected to the side end of the elastic steel plate 404. The second motor 401 is electrically connected to the button 306. In practice, when the limiting rod 305 slides to the bottom of the arc-shaped groove 204 and presses the button 306, it interacts with the button 306. When the electrically connected motor 401 is started, it drives the rotating rod 402 to rotate. The rotating plate 403 on the side of the rotating rod 402 drives the elastic steel plate 404 and the inclined striking head 405 to swing back and forth, continuously striking the ball cylinder 1. The vibration of the ball cylinder 1 is transmitted to the internal ball 103. With the help of several holes on the dispersing plate 104, it can not only assist the rapid discharge of materials in the cylindrical trough, but also disperse the agglomerated materials, ensuring that the materials enter the pyrolysis furnace evenly. At the same time, the fully sealed design eliminates the risk of gas leakage, solving the safety and discharge problems of traditional material conveying.

[0024] Working principle: When the feeding device is working, the state of the ball 103 is first adjusted by the rotating component 3 to achieve sealed feeding. The motor 301 starts and drives the rotating rod 302 to rotate. The ball 103, which is fixed at the bottom of the rotating rod 302, rotates in the ball cylinder 1. When the cylindrical groove on the side of the ball 103 is aligned with the left feed pipe 101, the motor 301 stops. At this time, the dispersion plate 104 on the inner wall of the cylindrical groove is directly opposite the feed port. The material can enter the cylindrical groove through the feed pipe 101. The closed end of the ball 103 without groove is attached to the inner wall of the ball cylinder 1. With the inclined feed pipe 101 to the discharge pipe 102 structure, a sealed space is formed, which completely blocks the harmful gas in the pyrolysis furnace from entering the silo or leaking out, avoiding air pollution and personnel health risks.

[0025] After feeding is completed, motor 301 starts again, driving ball 103 to rotate, so that the cylindrical groove is aligned with the right discharge pipe 102. During this process, the extension plate 304 on the side of the outer sleeve plate 303 of rotating rod 302 drives the limiting rod 305 to slide along the arc groove 204 of base 201. When the limiting rod 305 slides to the bottom of the arc groove 204 and presses button 306, motor 401, which is electrically connected to button 306, starts. Motor 401 drives rotating rod 402 to rotate. The rotating plate 403 on the side of rotating rod 402 drives the elastic steel plate 404 and the inclined striking head 405 to swing back and forth, continuously striking the ball cylinder 1. The vibration of the ball cylinder 1 is transmitted to the internal ball 103. With the help of several holes on the dispersing plate 104, it can not only assist the material in the cylindrical groove to be discharged quickly, but also disperse the agglomerated material, ensuring that the material enters the pyrolysis furnace evenly. At the same time, the fully sealed design eliminates the risk of gas leakage, solving the safety and feeding problems of traditional material conveying.
