Abstract

The utility model relates to a low-speed overweight centrifugal spray dryer pertaining to a chemical engineering equipment and resolves the problem that the traditional sprinkler has a high rotary speed and a big turbine-driven compressed air consumption, is easy to damage and difficult to radiate the heat at the inner wall of the dryer. The technical proposal is that the sprinkler uses a overweight machine structure to obtain an required spraying effect under the low speed operation; uses a forced air cooling method to lower the temperature at the inner wall of the dryer; uses the force generated by blowing the device wall to reactively thrust the sweeping pipe for rotation; also, uses a micro electric motor to drive packing auger, thereby canceling the turbine and the compressed air by the turbine. The utility model has a low-speed and long-life sprinkler, a lower inner wall temperature of the dryer, a material not glued to the wall, a simple dryer body structure, a lower cost, a reliable operation and a high efficiency, and can be used for the drying equipment for various hydro materials.
