Abstract
The invention relates to a drum vacuum dryer. The drum vacuum dryer comprises a vacuum drying chamber, a hopper, a discharging device, an elbow, an air duct, a vacuum unit, a riding wheel bracket, a driving device, a heating device, a gear ring, a fan, a sealing device and a bracket. The vacuum drying chamber comprises a heating chamber, a drying chamber and a heat conducting working medium; the riding wheel bracket fixedly supports the vacuum drying chamber and is provided with a feed opening and a discharge opening. A flange-free end of the elbow and the feed opening and the discharge opening of the vacuum drying chamber are hermetically connected into a whole by the sealing device, and an end with a flange of the elbow is fixedly connected into a whole with the discharging device. Whenthe vacuum drying chamber is driven to rotate by the driving device, the air duct and the elbow are stationary, and the joint of the air duct and the elbow is sealed and airtight. The heat energy of the heating device heats a material, conducts heat to the material and radiates heat from the material through the heat conducting working medium, so that the heat conversion efficiency is high and theloss is small; the dried material is cooled in a cooling section, so that the material drying efficiency is improved, and the material drying effect is optimized. When one heat pipe is damaged and leaks, the use of the whole drum vacuum dryer is not affected.
Description
technical field [0001] The invention relates to a drum dryer, in particular to a drum vacuum dryer. Background technique [0002] Nowadays, in the processing and production fields of grain, food, chemical industry, medicine, agricultural by-products, pasture, etc., it is necessary to heat and dry the materials under vacuum conditions; the heat exchange of the drying chamber of the drum dryer on the market is mostly in the form of exhaust pipes. , Interlayer heating method for heat exchange and heat dissipation, but their radiators are large in size, small in heat dissipation area, and low in efficiency of heat energy use. Wet materials often form agglomerates under vacuum, which causes uneven drying of wet materials and affects the drying quality of materials. The drying chamber of the drum dryer on the market now has a high failure rate during use. The heat dissipation pipe in the drying chamber is worn by the material during the heat conduction and heat exchange process. ...
