Description

Technical Field

[0001] This utility model relates to the field of lithium resource processing technology, and in particular to a heat-dissipating ball mill for crushing lithium-containing clinker. Background Technology

[0002] Ball mills are key equipment that use steel or ceramic balls inside a rotating cylinder as grinding media to crush and mix materials. They are widely used in industries such as cement, mineral processing, and chemicals, and can be divided into dry and wet grinding methods.

[0003] Existing ball mills for lithium clinker use an electric motor to drive the cylinder to rotate. The cylinder is filled with grinding media. When the cylinder rotates, these grinding media move with it, repeatedly impacting and rubbing the lithium clinker material inside. Under the continuous action of the grinding media, the material is gradually crushed into fine particles.

[0004] However, during the ball milling process, a large amount of heat is generated due to the frequent and intense impacts and friction between the grinding media and the material, as well as between the grinding media themselves. If this heat cannot be dissipated in time, the overall temperature of the ball mill will continue to rise. When the temperature exceeds the limit that the equipment can withstand, it is very likely to cause overheating, which will damage the internal components of the equipment and seriously affect the normal operation and service life of the equipment. Therefore, this utility model provides a heat dissipation ball mill for crushing lithium clinker. Utility Model Content

[0005] For existing ball mills used for lithium clinker, a large amount of heat is generated during the ball milling process. If this heat cannot be dissipated in time, it may cause overheating of the equipment, which in turn damages the internal components and seriously affects the normal operation and service life of the equipment.

[0006] The technical solution of this utility model is as follows: a heat-dissipating ball mill for crushing lithium-containing clinker, including a first fixed frame; it also includes a drum and a crushing assembly; a second fixed frame is provided at the upper end of the first fixed frame, and an outer shell is provided between the first fixed frame and the second fixed frame; a crushing assembly is provided at the upper end of the second fixed frame; a drum is provided inside the outer shell; a circulating cooling pipe for absorbing heat is provided between the drum and the outer shell; a water pump is provided at one end of the circulating cooling pipe; a liquid extraction pipe is provided on one side of the water pump; a coolant tank is provided on one side of the liquid extraction pipe; a liquid outlet pipe is provided at the other end of the circulating cooling pipe; a cooling device for cooling the liquid is provided on one side of the liquid outlet pipe; a liquid inlet pipe is provided on one side of the cooling device; the liquid inlet pipe is fixedly connected to the coolant tank; a discharge pipe is provided at the lower end of the drum; a sieve plate is provided inside the drum; and grinding balls are provided on the sieve plate.

[0007] Preferably, a toothed ring is provided on the outer side of the drum, a first motor is provided on the upper end of the first fixed frame, and a first gear is provided on the output end of the first motor, which meshes with the toothed ring.

[0012] Preferably, the crushing box has a slot four, and the second crushing roller is rotatably connected to the inside of the crushing box through the slot four.

[0013] The beneficial effects of this invention are as follows: Compared to traditional ball mills for lithium clinker, which generate a large amount of heat during the grinding process, this device addresses the issue of overheating. If this heat cannot be dissipated in time, it can lead to overheating, damaging internal components and severely impacting the equipment's normal operation and lifespan. This device uses a water pump to draw coolant through a suction pipe and deliver it to a circulating cooling pipe. The coolant in the circulating cooling pipe absorbs the heat generated during grinding, then exits through an outlet pipe into a cooling device for further cooling. Finally, it returns to the coolant tank through an inlet pipe for further circulation, significantly improving heat dissipation efficiency and effectively preventing overheating. This reduces downtime for maintenance and increases production efficiency. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5This utility model provides an embodiment: a heat-dissipating ball mill for crushing lithium-containing clinker, including a first fixed frame 1; it also includes a drum 401 and a crushing assembly; a second fixed frame 3 is provided at the upper end of the first fixed frame 1, and a shell 2 is provided between the first fixed frame 1 and the second fixed frame 3; the crushing assembly is provided at the upper end of the second fixed frame 3; the drum 401 is provided inside the shell 2; a circulating cooling pipe 402 for absorbing heat is provided between the drum 401 and the shell 2; a water pump 403 is provided at one end of the circulating cooling pipe 402; and a liquid pumping device is provided on one side of the water pump 403. Pipe 404, a coolant tank 405 is provided on one side of the liquid extraction pipe 404, a liquid outlet pipe 406 is provided at the other end of the circulating cooling pipe 402, a cooling device 407 for cooling the liquid is provided on one side of the liquid outlet pipe 406, a liquid inlet pipe 408 is provided on one side of the cooling device 407, and the liquid inlet pipe 408 is fixedly connected to the coolant tank 405. A discharge pipe 409 is provided at the lower end of the drum 401, a sieve plate 410 is provided on the inner side of the drum 401, grinding balls 411 are provided on the sieve plate 410, a toothed ring 412 is provided on the outer side of the drum 401, and a first fixed frame 1 is provided at the upper end. A first motor 413 has a first gear 414 at its output end, which meshes with a gear ring 412. Starting the first motor 413 causes the first gear 414 to rotate, which in turn drives the gear ring 412 to rotate, thus causing the gear ring 412 to rotate the roller 401. A slot is provided on the first fixed frame 1, through which the roller 401 is rotatably connected to the inner side of the first fixed frame 1. The roller 401 acts as a limit, and the water pump 403 is started. The water pump 403 draws out the coolant through the liquid extraction pipe 404 and delivers it to the circulating cooling pipe 402. The coolant in the circulating cooling pipe 402 absorbs the temperature generated by the grinding balls 411 during grinding, and then is discharged through the liquid outlet pipe 406. It then enters the cooling device 407 for cooling through the liquid outlet pipe 406, and returns to the coolant tank 405 through the liquid inlet pipe 408 for circulation. This greatly improves the heat dissipation efficiency, effectively prevents the equipment from overheating, reduces equipment downtime for maintenance, and improves production efficiency.

[0022] Please see Figures 4-5In this embodiment, the crushing assembly includes a crushing box 501. The crushing box 501 is mounted on the upper end of the second fixed frame 3, and a feeding pipe 502 is mounted on the lower end of the crushing box 501. A second motor 503 is mounted on one side of the crushing box 501, and a first crushing roller 504 is mounted on the output end of the second motor 503. A second gear 505 is mounted on the outer side of the first crushing roller 504, and a third gear 506 is mounted on one side of the second gear 505. The third gear 506 meshes with the second gear 505, and a second crushing roller 507 is mounted on the inner side of the third gear 506. A second groove is formed on the roller 401, and the feeding pipe 502 is located above the second groove. The crushed material enters the drum 401 through the second groove. The crushing box 501 has a third groove, and the first crushing roller 504 is rotatably connected to the inside of the crushing box 501 through the third groove. The third groove on the crushing box 501 allows the first crushing roller 504 to be rotatably connected to the inside of the crushing box 501, thus limiting the position of the first crushing roller 504. The crushing box 501 has a fourth groove, and the second crushing roller 507 is rotatably connected to the inside of the crushing box 501 through the fourth groove. The fourth groove on the crushing box 501 allows the second crushing roller 507 to be rotatably connected to the inside of the crushing box 501, thus limiting the position of the second crushing roller 507.

[0023] During operation, the second motor 503 is started, which drives the first crushing roller 504 to rotate. The first crushing roller 504 drives the second gear 505 to rotate, the second gear 505 drives the third gear 506 to rotate, and the third gear 506 drives the second crushing roller 507 to rotate. The first crushing roller 504 and the second crushing roller 507 rotate inward simultaneously. Then, the lithium-containing clinker raw material is added to the crushing box 501. The lithium-containing clinker raw material is initially crushed by the first crushing roller 504 and the second crushing roller 507. The crushed raw material is discharged through the feed pipe 502 and then falls into the drum 401 through the trough. The first motor 413 is started, which drives the first gear 414 to rotate. 4 drives the gear ring 412 to rotate, which in turn drives the drum 401 to rotate. The rotation of the drum 401 causes the grinding balls 411 to repeatedly impact and rub the lithium raw material, gradually crushing it into fine particles. The qualified lithium raw material passes through the sieve plate 410 and is finally discharged through the discharge pipe 409. While the grinding balls 411 are grinding, the water pump 403 is started. The water pump 403 draws out coolant through the liquid extraction pipe 404 and delivers it to the circulating cooling pipe 402. The coolant in the circulating cooling pipe 402 absorbs the temperature generated by the grinding balls 411 during grinding, and then discharges it through the liquid outlet pipe 406. The coolant then enters the cooling device 407 for cooling through the liquid outlet pipe 406, and returns to the coolant tank 405 through the liquid inlet pipe 408 for circulation.

[0024] Through the above steps, by starting the water pump 403, the water pump 403 draws out the coolant through the liquid extraction pipe 404 and delivers it to the circulating cooling pipe 402. The coolant in the circulating cooling pipe 402 absorbs the temperature generated during the grinding of the grinding balls 411, and then discharges it through the liquid outlet pipe 406. The coolant then enters the cooling device 407 for cooling through the liquid outlet pipe 406, and returns to the coolant tank 405 through the liquid inlet pipe 408 for circulation. This greatly improves the heat dissipation efficiency, effectively prevents the equipment from overheating, reduces equipment downtime for maintenance, and improves production efficiency.
