Embodiment Construction
[0013] As shown in the figure, the lower layer of the flexible electric preheating plate 1 is provided with an electric heating layer 2. The electric heating layer is composed of magnetic powder, graphite and silicon rubber mixing press plate. A heat reflecting layer 3 is pasted on the upper part of the electric heating layer. Layer 4, more than two electric connection holes 5 are arranged on the flexible electric preheating plate unit, and the depth of the electric connection holes reaches the electric heating layer. The electrical connection hole can be embedded in the conductive connector 6.1 of the conductive connecting wire 6, and the conductive connector is arranged at both ends of the conductive connecting wire 6. When the conductive connection wire is connected to the flexible electric heating plate, it can be connected in parallel or in series, and its connection end leads out the live wire 1.1 and the neutral wire 1.2, and is connected with the mains to provide power ...

The invention provides an electric preheating plate for coating a steel plate for a ship. A lower layer of the flexible electric preheating plate is provided with an electric heating layer consisting of magnetic powder, graphite and a mixing silicon rubber pressing plate, wherein a heat reflecting layer is pasted on the upper part of the electric heating layer, and a heat insulating and insulating layer is adhered on the heat reflecting layer; the flexible electric preheating plate unit is provided with more than two electrical connection holes, and the depths of the electrical connection holes directly reach the electric heating layer; the electrical connection holes can be embedded into conductive contacts of a conductive connecting line, and the conductive contacts are arranged at bothends of the conductive connecting line; when the conductive connecting line is connected to the flexible electric heating plate, the conductive connecting line can be connected in parallel or in series; and the connecting end of the conductive connecting line leads out a fire line and a zero line and is connected with the mains supply for providing a power supply for the flexible electric heatingplate. The electric preheating plate can be laminated with a steel plate via magnetism and cut according to the shape of the steel plate, and the heating plate unit is convenient for combination and circuit connection. The electric preheating plate has the advantages of convenient lamination, energy saving and long service life and is suitable for preheating the steel plate during coating the steel plate for a ship.
Description
technical field [0001] The invention proposes a heating device in the field of thermal engineering, specifically an electric preheating plate coated with steel plates for ships. Background technique [0002] Before the present invention was proposed, when steel plate was coated with paint under cold conditions, it was necessary to heat the steel plate. Heating usually adopts electric blanket structure, that is, an electric heating wire is installed in the package, and the steel plate is heated by the electric heating wire, so as to increase the temperature of the coated steel plate and facilitate the drying of the paint. [0003] The disadvantages of this electric blanket are that it is not resistant to folding, the temperature is not easy to control, the service life is short, and the temperature cannot be automatically adjusted according to the temperature. [0004] Someone also proposed a patent application for a steel plate coating electric heating device, the technical...
