Description

Technical Field

[0001] The utility model relates to the technical field of pyrolysis of waste lithium batteries, in particular to a water-cooled high-temperature furnace for pyrolysis of waste lithium batteries. Background Art

[0002] In the recycling of waste lithium batteries, one of the steps is high-temperature roasting, which is generally carried out in a pyrolysis high-temperature furnace. After roasting in the pyrolysis high-temperature furnace, the temperature is relatively high. If it is not cooled down and directly enters the next step, it will cause damage to subsequent equipment and pipelines. Therefore, it is necessary to cool down the pyrolysis high-temperature furnace to reduce the temperature of the powder and gas coming out of the pyrolysis high-temperature furnace. The cooling device in the prior art has a poor cooling effect, because the material coming out of the pyrolysis high-temperature furnace needs to go through a certain cooling path to achieve the cooling effect.

[0003] The patent publication number CN220728888U was retrieved. The patent name is a public material of a waste lithium battery pyrolysis high-temperature furnace with a cooling device. It specifically discloses a waste lithium battery pyrolysis high-temperature furnace with a cooling device, including a furnace body, the furnace body is horizontally arranged, and is used to pyrolyze waste lithium batteries; a driving device, the driving device includes a roller ring fixed on the outer side of the furnace body, and the roller ring is connected to a motor that provides power through a transmission device; a feeding and discharging device, the feeding and discharging device includes a feeding screw arranged at one end of the furnace body and a discharging port arranged at the other end of the furnace body; a cooling device, the cooling device includes a cooling cover, and a water spray pipe is arranged inside the cooling cover, and the water spray pipe sprays water to the outer side of the furnace body to cool it down; an anti-outflow device, the anti-outflow device includes a water baffle plate arranged on the outer side of the furnace body, and the water baffle plate is arranged on the inner side of the cooling cover. The discharge end of the high-temperature furnace can be cooled, and the temperature of the outlet end of the high-temperature furnace can be reduced by adding a cooling device.

[0004] By analyzing the above-mentioned public materials, it can be seen that although it is possible to cool down the waste lithium battery after it is discharged from the high-temperature pyrolysis furnace, there is only a short-distance cooling hood, and it is difficult to quickly cool down the material after passing through the high-temperature pyrolysis furnace.
