Problems solved by technology
Due to the uneven distribution of internal temperature in the traditional internal heating oven, it is difficult to remove the moisture in the part with low local temperature, and the cooling speed is very slow, which affects the production efficiency
Recently, a rotary oven with oil circulation heating has appeared, which can be heated evenly, and can be cooled by oil circulation, and the cooling efficiency is also high, but it is not safe to use oil heating at a high temperature

Embodiment Construction
[0015] Such as figure 1 As shown, the rotary lithium ion powder baking oven is composed of a rotatable furnace 3 supported on the support member 11 at both ends, an electric heating furnace left half of the furnace body 1 and a right half of the furnace body 2 located on the periphery of the furnace, and the furnace The driving mechanism, the material inlet 5, the material outlet 6, the vacuum inlet and outlet interface 7, and the nitrogen inlet and outlet interface 8 constitute.
[0016] The furnace body of the electric heating furnace is composed of a left half furnace body 1 and a right half furnace body 2 which can be opened and closed. The necks at both ends of the furnace 3 are supported on the support rod 11, and the upper neck is higher than the lower neck, so that the furnace is inclined.
[0017] When the oven is heating, the left half of the furnace body 1 and the right half of the furnace body 2 of the electric heating furnace are closed to heat the furnace 3 ( ...

The invention discloses a rotary lithium battery powder oven which comprises a rotary furnace pipe, a heating furnace and a furnace pipe driving mechanism. A bulging part in the middle of the furnace pipe is a cavity and surrounded by the heating furnace, necks at two ends of the furnace pipe extend out of the electric heating furnace to be connected with supporting rods, and the furnace pipe driving mechanism drives the furnace pipe to rotate around a pivot at two ends of the furnace pipe; a feed inlet, a discharge outlet, a vacuum in-and-out connector and a nitrogen in-and-out connector are respectively arranged on neck portion of the furnace pipe; a spiral piece is arranged in the cavity of the furnace pipe and hinged to the inner wall of the furnace pipe to rotate together with the furnace pipe. The heating furnace can be composed of a left half furnace body and a right half furnace body which are openable; the heating mode of the heating furnace is electrical resistance wire heating or infrared heating or microwave heating. By the openable external heating type structure, temperature falling process is quickened; by the application of the spiral piece in the cavity of the furnace pipe, powder can be heated evenly, conductive agents and active substances in the powder are enabled to be mixed evenly, and security is high.
Description
technical field [0001] The invention relates to a rotary lithium battery powder baking oven. Background technique [0002] In the process of lithium battery preparation, moisture has a great influence on the battery. Therefore, powder baking in the lithium ion battery manufacturing process is a key link in the lithium battery manufacturing process. How to effectively and efficiently remove the moisture in the powder becomes powder baking. urgent problem to be solved. Due to the uneven distribution of internal temperature in the traditional internal heating oven, it is difficult to remove the moisture in the part with low local temperature, and the cooling speed is very slow, which affects the production efficiency. Recently, a rotary oven with oil circulation heating has appeared, which can be heated evenly, and can be cooled by oil circulation, and the cooling efficiency is also high, but it is not safe to use high oil heating temperature.
