Problems solved by technology

When the heat conduction medium (water, heat transfer oil) in the heating plate of the drying oven and drying room flows and conducts heat in the heating plate for a long time, scale and oil will form on the plate inside the heating plate. The internal structure of the heating plate is complicated, and the inside of the heating plate The scale and oil on the plate body are not easy to clean and descale, and the heating plate with scale and oil will affect the conduction and heat transfer of heat energy
Due to the flow direction of the heat conduction medium in the heating plate, the temperature of the bottom plate of the heating plate and the four corners of the bottom plate and the surrounding areas are uneven, and the uneven temperature of the bottom plate and the four corners of the bottom plate and the surrounding areas of the heating plate causes uneven drying of materials
In some drying ovens and drying rooms, the hot air from the external heat exchange directly dries the materials, which may cause the hidden danger of the materials being polluted.

Abstract

The invention discloses a heat pipe type vacuum drying box. The heat pipe type vacuum drying box comprises a drying box body, a heating device, a support and a water draining valve. A heat energy inlet, a heat energy outlet, an exhaust opening and a water draining opening are formed in the drying box boxy, the water draining valve is arranged on the water draining opening of the outer face of the drying box, the heating device is fixedly mounted on a box main body of the drying box body through the support, and the heating device comprises a top plate, a bottom plate, side plates, a heating pipe, a fixed strip, and a heat conduction working medium, the heat conduction working medium rapidly transmits the heat to the top plate and the bottom plate of the heating device through the gas and liquid phase change, balance temperature on the four corners and the periphery of the top plate and the bottom plate of the heating device ensures the material water drying uniformity, the upper and the lower of the heating device carry out simultaneous heating, the heat conduction and exchange speed of the heat energy is improved, the material drying speed is improved, and the heat working media cannot generate water scale and oil scale in the heating device, and the heat pipe type vacuum drying box flexibly selects vacuum low-temperature drying or air convection drying.

Description

technical field [0001] The invention relates to a drying oven, in particular to a heat pipe type vacuum drying oven. Background technique [0002] At present, the main heating method of drying ovens or drying rooms on the market is to pass a flowing heat transfer medium into the heating plate. The heat transfer medium in the heating plate transfers heat to the material in the tray through the heating plate, and the material absorbs heat to evaporate its water. Gasification, water vapor is drawn away by the exhaust device. When the heat conduction medium (water, heat transfer oil) in the heating plate of the drying oven and drying room flows and conducts heat in the heating plate for a long time, scale and oil will form on the plate inside the heating plate. The internal structure of the heating plate is complicated, and the inside of the heating plate The scale and grease on the plate body are not easy to clean and descale, and the heating plate with scale and grease will a...
