Three drum dryer structure description: three drum dryer is the introduction of Germany advanced technology of today, consists of three concentric cylinders of different diameters according to certain mathematical relationships and structure, embedded in combination with each other. Three drum dryer can be adapted to a variety of fuels coal, oil, gas, etc., can dry bulk, granular, powder and other materials to create environment-friendly line with national policy resource-saving society, is an alternative to traditional baking Dry equipment and environment friendly products. According to the principle of thermal power, cylinder with different angles and spacing of lifting plate and guide plate, this structure can ensure the material is dried under gravity along the direction of movement of the spiral movement, in the barrel to maintain sufficient residence time and full dispersion, resulting in the material in the barrel chamber and the combustion gas stream from the heat exchange heat sufficiently to eliminate the conventional drying equipment often appear small cross-sectional area of ??the heat exchange caused by the tunnel, the low intensity of defects per unit volume of the evaporator . Special three tube structure, the inner cylinder and the outer cylinder tube is surrounded by the formation of a thermal insulation system itself, inside the cylindrical surface of the heat involved in the outer layer of material of the heat exchange cylinder and the outer cylinder and at the In the low temperature end of the heat flow, so the heat dissipation area and heat losses significantly lower cylinder. Energy-efficient three-cylinder drying function make full use of waste heat, reduce heat loss and increase heat exchange area, so that the dryer unit volume strength greatly increased evaporation, thus effectively improving energy efficiency, reducing energy consumption, so that the three cylinder drying thermal efficiency dryer has been improved greatly. Three drum dryer structure: Due to the special structure of the sleeve of the dryer, the length of the cylinder is the third single cylinder dryer, base area than monocular dryer saves about 65%, the underlying investments reduced accordingly . The dryer uses friction drive roller and wheel belt, transmission power is low, the device reduces the noise at work. Sealing system uses a micro-contact technology, better seal, reducing the dust pollution. Three drum dryer for the beginning of the water is not very high, moderate proportion of liquidity drying process the material is characterized by changes in the general design. With a compact, small footprint, is one area of ??the same production single cylinder drying ground dichotomy, reliable, low power consumption, high thermal efficiency, good material drying effect, easy to automate control and less operator . Three drum dryer Features: 1, equipment investment is required for imported products 6/1. 2, using the new modular lifting devices. Material below 0.5% final moisture to ensure that the desired final moisture indicators easily regulated according to user requirements. 3, self-cylinder insulation thermal efficiency up to 80% (conventional single cylinder dryer thermal efficiency of only 35%) to improve the thermal efficiency of over 40%. 4, the fuel can be adapted to coal, oil, gas. 5, than monocular dryer footprint reduced by about 50%, about 50% lower construction investment, power consumption of less than 60%. 6, the use of alloy steel plate manufacture than ordinary wear and four times, the whole amount of maintenance is very small. 7, the outlet temperature is low, long time dedusting equipment. 8, the use of wheel rotation, transmission power is small. 9, speed arbitrary regulation, material, wind, coal balanced three-parameter process
