Drying device for heating sludge and fecal material at high speed by rotating inner and outer double kettles and energy balls

Abstract

The invention relates to a drying device for heating sludge and fecal material at a high speed by rotating inner and outer double kettles and energy balls. The device comprises a smoke hood, an inner kettle, a supporting plate, an outer kettle, a riding wheel I, an insulating sleeve, a transmission wheel, a supporting plate II, a feeder, a riding wheel II and a sealing cover, wherein the inner kettle is connected to the inner side of the outer kettle through the supporting plates I and II in a welding manner; the insulating cover is arranged outside the outer kettle and is filled with an insulating material; the riding wheel I, the transmission wheel and the riding wheel II are separately arranged outside the insulating cover; the smoke hood and the sealing cover which are in engaged contact are arranged at two ends of the insulating cover; and the feeder is fixed in the middle of the sealing cover and extends into the inner kettle. Excessive energy balls absorb heat and exchange heat with materials quickly to dehydrate, and moreover, the dried materials are automatically separated in rotation, and the energy balls circularly operate continuously automatically, so that the device is an efficient sludge dehydrating device.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a drying device for heating sludge and feces at high speed by rotating inner and outer double kettles and energy balls. Background technique [0002] Cities, including rural areas, discharge a large amount of sewage every day. The sewage contains a small amount of sludge. These activated sludge generally still contain about 70-80% of water after dehydration. Direct discharge will cause secondary pollution because the water content is too high. At present, there is no very good and efficient dehydration drying method and equipment, and it is urgent to invent a dehydration and drying device with high efficiency and good dispersibility. Contents of the invention [0003] The purpose of the present invention is to avoid the deficiencies of the prior art and provide a drying device for rotating the internal and external double kettles and energy balls to heat sludge and dung at hig...
