▎ 摘　　要

NOVELTY - The device has a machine case (1) fixedly connected with a heating box (3) that is fixedly connected with a sampling box (301). The machine case is fixedly connected with a motor (4). An output end of the motor is fixedly connected with a rotating shaft (402). The rotating shaft is fixedly connected with a blade wheel blade and a stirring rod. The impeller blade is rotatably connected in the extracting box. The heating box is fixedly connected with sampling box. The machine case is provided with a filtering mechanism for filtering circulating hot oil. USE - Used as graphene wall heating automatic hot pressing constant temperature device. ADVANTAGE - The device: can keep the constant temperature of the circulating hot oil; supplements the heat loss during the circulating flow; filters the impurity doped in the circulating hot oil; and permanently prevents the machine body from damage caused by impurity abrasion. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene wall heating automatic hot pressing constant temperature device.
