The wet material is continuously added to the drying plate on the first layer of the upper part of the dryer from the feeder, and the rake arm with the rake leaves rotates to make the rake leaves continuously dig the material.
The material flows through the surface of the drying plate along an exponential spiral. The material on the small drying plate is moved to the outer edge and falls on the outer edge to the outer edge of the large drying plate below. On the large drying plate, the material moves in and falls from the middle. The material mouth falls into the next layer of small drying pan.
The large and small drying trays are arranged alternately up and down, so that the material can continuously flow through the entire dryer. A heating medium (saturated steam, hot water and heat transfer oil in the form of heating medium) is passed into the hollow drying plate, and the heating medium enters from one end of the drying plate and exits from the other end. The dried materials fall from the last layer of the drying plate to the bottom layer of the shell, and are finally moved by the rake leaves to the discharge port for discharge.
The water is drained from the moisture outlet provided on the top cover. It can also be equipped with auxiliary equipment such as finned heater, solvent recovery condenser, bag filter, dry material backmixing mechanism, induced draft fan, etc., which can improve the production capacity and effect of the dryer, and can also carry out pyrolysis and reaction operations. .
The disc dryer integrates the length of conduction drying and mixing and conveying. The structure adopts the ingenious combination of sheet metal stamping and welding large and small heating plates and swing adjustable rotary harrow blades, equipped with quantitative feeding and stepless speed regulation; the process adopts series and parallel connections Input heating medium and final cooling and cooling measures, the material layer is thin, the thermal resistance is small, the exposed surface is large, the heating area is 100% used, and the advantages of high utilization rate of conductive drying heat energy are fully utilized.
Practice has shown that the disc dryer has a novel and compact structure, continuous production, simple adjustment and maintenance, stable and reliable operation, high flexibility, high efficiency, low energy consumption, and controllable drying time. The product has the advantages of good quality, light labor intensity, good surrounding, less land occupation, and wide application.
