▎ 摘　　要

NOVELTY - Use self-heating silicon carbide-graphene composite ceramic film preparation technology in the oil-water separation, is claimed. The film comprises a processing device main body (1), whose four corners are fixedly installed with a supporting legs (2). The bottom end of the four supporting legs is rotatably provided with a wheel (3). The inner part of the processing device main body is provided with a cavity (4). The inner wall of the two sides of the cavity is slidingly installed with a moving plate (5). The bottom side respectively the processing device main body is slidingly installed with two attaching plates. The inner wall of the bottom side of the cavity is provided with a groove. A through hole is slidingly provided with a connecting rod. Two circulating tanks are provided with a hose. One end of the two circulating tanks far away from each other is provided with a long pipe. The processing device main body is provided with a collecting box. USE - The film preparation technology is useful in the oil-water separation. ADVANTAGE - The film solves the shortcomings in the prior art; allows people to move and transport the processing equipment body simply and conveniently; can adequately decelerate on the sloped ground; and ensures safety index is high. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for self-heating silicon carbide -graphene composite ceramic film preparation technology. DESCRIPTION OF DRAWING(S) - The drawing shows a self-heating SiC-graphene composite ceramic film preparation technology and the front view structure schematic diagram of the application in the oil-water separation. Processing device main body (1) Legs (2) Wheels (3) Cavity (4) Moving plate (5)
