▎ 摘　　要

NOVELTY - Graphene electric heating liquid concentrating device comprises a preheating tank (1), whose the right side is provided with a filter (6). The right side of the filter is provided with a concentrating tank (3). The right side of the concentrating tank is provided with a recycling tank (4). The right of the recycling tank is provided with a vacuum pump (5). The annular side surface of the concentrating tank and the annular side surface of the preheating tank are provided with a heating mechanism. The annular side of the preheating tank is sprayed with a first heat-conducting coating. The lower side of the annular side of the preheating tank is sleeved with a first supporting base. The upper end surface of the first supporting base is provided with a first protective cylinder. The annular side of the first protective cylinder is adhered with a first heat-insulating sheet and the second protective cylinder is provided with a second electric heating pipe. USE - Used as graphene electric heating liquid concentrating device. ADVANTAGE - The device: has reasonable structure, good heating effect, low maintenance cost and strong practicability; makes the second heat insulation sheet of the second protection cylinder heat insulation better and provides the first heat-insulating sheet of the better heat insulation to the first protection cylinder. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of the graphene electric heating liquid concentrating device. 1Preheating tank 3Concentrating tank 4Recycling tank 5Vacuum pump 6Filter
