A device utilizing rotary inner and outer kettles and energy balls and used for rapid sludge heating and manure material drying

Abstract

A device utilizing rotary inner and outer kettles and energy balls and used for rapid sludge heating and manure material drying is disclosed. The device includes a chimney cap, an inner kettle, a first supporting plate, an outer kettle, a first supporting wheel, a thermal insulation sleeve, a transmission wheel, a second supporting plate, a feeder, a second supporting wheel and a sealing sleeve. The inner kettle is connected and welded to the inner side of the outer kettle through the first and second supporting plates. The thermal insulation sleeve is outside the outer kettle and is filled with a thermal insulation material. The outside of the thermal insulation sleeve is provided with the first supporting wheel, the transmission wheel and the second supporting wheel. Two ends of the thermal insulation sleeve are provided with the chimney cap and the sealing sleeve respectively in a tight contact manner. The feeder is fixed in the middle of the sealing sleeve and penetrates into the inner kettle. Excessive energy balls are utilized to absorb heat so as to achieve rapid material heat exchange and dehydration, and a dried material is automatically separated during rotation. Trianglematerial shoveling hoppers are utilized to automatically shovel the energy balls and lift the energy balls so that the energy balls enter the feeder and are mixed with a material, with operation being cyclic. The device is an efficient sludge dehydration device.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a device for drying sludge and manure for high-speed heating of 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 rotating internal and external double kettle and an energy ball high-speed heating sludge and dung drying device....
