Description

Technical Field

[0001] This utility model relates to the field of screw conveyor technology, specifically a circulating water-cooled screw conveyor. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as positive / negative electrode materials and a non-aqueous electrolyte solution. After prolonged use, lithium-ion batteries age and need to be recycled. Recycled lithium-ion batteries can be used for resource recovery, extracting valuable metals such as lithium, cobalt, and nickel. These metals can be used to manufacture new battery materials, circuit boards, etc. Furthermore, recycled lithium-ion batteries can be used in new energy vehicles and energy storage. In the energy storage field, recycled lithium-ion batteries can be used to create large-scale energy storage systems for use in homes, businesses, and industries, playing an important role in balancing the power grid. During the recycling process, the high temperature of the lithium-ion battery powder can cause deformation of ordinary conveying equipment, necessitating the use of a circulating water-cooled screw conveyor to cool the high-temperature lithium-ion battery powder. However, to ensure its stability and performance in subsequent processes, existing circulating water-cooled screw conveyors achieve water cooling through a water-cooled screw shaft and a water-cooled outer shell. The screw shaft has through holes inside and rotary joints on both sides to facilitate cooling water circulation. Simultaneously, a water-cooled outer shell is provided on the outer surface of the conveying pipe. The screw shaft and the water-cooled outer shell form a water-cooled circulation zone. During use, high-temperature lithium battery powder is conveyed through rotating screw blades, and cooling water continuously circulates within the screw shaft and the water-cooled outer shell to achieve the water cooling effect. Traditional circulating water-cooled screw conveyors have multiple cooling water circulation zones, each requiring a circulation pump. Relying solely on a single cooling water source to absorb heat and cool the high-temperature lithium battery powder results in poor water cooling performance. Therefore, we propose a circulating water-cooled screw conveyor. Utility Model Content

The lower end of the spiral shaft 4 is fixedly connected to the upper end of the rotating end of the second rotary joint 552.

With the cooling mechanism 5, only one circulating pump is needed to cooperate with the secondary cooling of the spiral coil 52 to simultaneously perform water cooling on the conveying pipe 2 and the spiral shaft 4, which improves the water cooling effect of the circulating water-cooled spiral conveyor.

[0026] The working principle of the circulating water-cooled screw conveyor provided by this utility model is as follows: When using the circulating water-cooled screw conveyor to transport high-temperature lithium battery powder, the high-temperature lithium battery powder enters the conveying pipe 2 from the feed pipe 6. The single-chip microcomputer 10 controls the operation of the second motor 9, which drives the screw shaft 4 to rotate through the pulley 8. The screw blades also rotate, driving the lithium battery powder to move towards the discharge pipe 7, and then discharge it from the discharge pipe 7. During this process, the external circulation pump works, pumping cooling water into the water-cooling chamber 551 through the rotary joint 552. Inside, cooling water absorbs the temperature of the lithium battery powder, creating a water-cooling effect on the spiral shaft 4 and spiral blades. It then enters the spiral coil 52 through rotary joint 51. Rotary joints 51 and 552 ensure that cooling water is delivered while the spiral shaft 4 rotates. However, as the cooling water passes through the water-cooling chamber 551, its temperature increases due to heat exchange, reducing the water-cooling effect and requiring secondary cooling. The microcontroller 10 controls the axial fan 555 and motor 56. The output shaft of motor 56 drives the connecting rod 53 to rotate, and the sponge roller 54 also... As it moves, the water tank 57 is filled with water. The sponge roller 54 revolves around the output shaft of the motor 56 and also rotates due to friction with the outer edge of the spiral coil 52. When the sponge roller 54 passes the water tank 57, it absorbs a large amount of water, leaving water stains on the surface of the spiral coil 52 as it passes the outer edge. At this time, the axial fan 555 accelerates the external air and guides it into the air duct 3. When the high-speed airflow passes over the surface of the spiral coil 52, it carries away some heat, thus cooling the spiral coil 52. The water creates a cooling effect, and the high-speed airflow causes the water stains on the surface of the spiral coil 52 to evaporate and absorb heat again. The heat transfer of the high-speed airflow and the evaporation of the water stains create a secondary cooling effect on the cooling water inside the spiral coil 52. The cooled water after the second cooling enters the cooling shell 553 and absorbs the heat emitted by the conveying pipe 2. At the same time, the high-speed airflow blows across the surface of the cooling shell 553. The gear-shaped cross-section of the cooling shell 553 has a larger contact area with the high-speed airflow, and the high-speed airflow can better remove the heat emitted by the cooling shell 553, thus improving the water cooling effect of the high-temperature lithium battery powder.

[0027] It is worth noting that the microcontroller 10 disclosed in the above embodiments is an APM32F407ZGT6 microcontroller, the axial fan 555 is a T35-11 axial fan, the first motor 56 is an SR1G6Z6M motor, and the second motor 9 is a YL100L-4 motor. The operation of the axial fan 555, the first motor 56, and the second motor 9 are all controlled by methods commonly used in the prior art.
