Paddle Dryer

Product Detail

Paddle dryer is composed of two to four propeller shafts, meshed with the jacket on theW shaped shell, frame and transmission parts, the material of the whole drying processcarried out in a closed state, volatile organic gases and peculiar smell gas in a sealedatmosphere is sent to the exhaust gas treatment device, avoid the pollution of the environment. Dryer to steam, hot water or heat conducting oil as the heating medium,rotating joint is provided with a heat transfer medium is derived and the shaft end. The heating medium is divided into two parts, respectively, into the dry shell jacket and a blade shaft cavity, the device body and a blade shaft simultaneously heated byconduction heating mode, heating and drying of materials. The raw material to be driedby the spiral feeder quantitative continuously fed into the drier feed inlet, the material into the machine behind him, through the rotation of the blade material turnover,stirring, constantly updated heating interface, and a transformer body and a bladecontact, is heated sufficiently, make the surface moisture evaporating materialcontained. At the same time, the material with the paddle shaft rotation into the spiral trajectory to the direction of a discharge port conveying, continue stirring in thetransportation, so that sludge oozing water to evaporation. Finally, uniform drying of qualified products by discharging port.

The characteristics of equipment

A. device structure is compact, small footprint devices. By the structure of the equipment is knowable, required to dry heat is mainly provided by the hollow blade wallare arranged on the hollow shaft surface, and the jacket wall surface heat transferaccounts for only a small part of. So heat transfer per unit volume of equipment is large,can save equipment floor area, less capital investment. High utilization rate of heat and b.. Sludge dryer by conductive heating heating, heat transfer surface were covered all the material, the heat loss is reduced; no hot air away heat, the heat utilization rate can reach more than 90%. C. wedge blade with self purification ability, can improve the heat transfer effect of the blade. Dispersion force rotating blades inclined plane and particleor powder layer joint motion generated, clear so attached to the heating on the inclined plane sludge automatically, keeping the heat transfer function of efficient blade. In addition, because the two axis blade to rotate reversely, alternately subsection compression (in two blade surface apart recently) and expansion (in two blade surface of the most distant when) mixing function, uniform heat transfer, improves heat transfereffect.
