AI Technical Summary
Existing cabinet-type graphite green blank roasting furnaces cause excessively high temperatures at the edges when processing deep-fired graphite green blanks. Users need to reach into the high-temperature furnace to retrieve them, increasing the risk of burns and reducing efficiency. At the same time, it is difficult to provide uniform heating to the center, resulting in unstable product quality.
A graphite green embryo calcination furnace was designed. The furnace uses heating coils and heating fans in conjunction with multiple conveying pipes to achieve uniform distribution of hot air. The heating position is dynamically adjusted by a rotating disk with nozzles. Combined with a cylinder pushing a pusher plate, the graphite green embryo is pushed to the front of the furnace, avoiding manual contact with the high-temperature area and ensuring uniform heating in the center.
It improves operational safety and convenience, ensures uniform heating of graphite green blanks, enhances product quality and production efficiency, improves heating uniformity, and reduces the risk of burns.
