Heat tube heating plate

Abstract

The invention discloses a heat tube heating plate. The heat tube heating plate comprises a top plate, a bottom plate, side plates, heating devices, heat conduction strips and a heat conduction workingmedium. The side plates are L-shaped, the plate surfaces at the lower ends of the side plates are equivalent to the bent parts of the L shapes, four edges of the lower surface of the bottom plate andthe lower ends of the four side plates are fixedly connected into a whole, and four edges of the top plate and the upper ends of the four side plates are fixedly connected into a whole. The heat conduction strips and the top plate are fixedly connected into a whole. The heating devices are installed in U-shaped grooves at the joints of the lower end of the bottom plate and the side plates. The heat tube heating plate is a gravity heat tube, the heat conduction working medium is arranged inside the heat tube heating plate, the top plate and the bottom plate are a condensation section of the heat conduction working medium, and the heating devices are an evaporation section of the heat conduction working medium. According to the heat tube heating plate, the heat conduction working medium carries heat energy, passes the top plate and the bottom plate and simultaneously conducts heat conduction and heat exchange to materials, the heat conversion efficiency is high, the loss is small, and the heat conduction speed and the heat exchange speed are increased. The heat conduction working medium does not generate water scale and grease stains during long-time heat conduction and heating in the heat tube heating plate.

Description

technical field [0001] The invention relates to a heating plate, in particular to a heat pipe type heating plate. Background technique [0002] The heating plate of the vacuum mesh belt dryer uses heat conduction to provide heat to the material. The heating plate is installed close to the bottom of the upper conveyor belt. One-sided contact with heat medium (conveyor belt); when the heat conduction medium (water, heat transfer oil) in the heating plate flows and conducts heat in the heating plate for a long time, scale and oil scale will form on the plate inside the heating plate, and the internal structure of the heating plate is complicated , The scale and oil scale on the plate body of the heating plate is not easy to clean and descale, and the heating plate with scale and oil scale will affect the conduction and heat transfer of heat energy. [0003] The heat pipe heating plate currently on the market can only conduct heat conduction and heat exchange on the top plate a...
