Southeast manufacturing: the algae sludge drying machine - printing and dyeing sludge dryer - hollow paddle dryer KJG series hollow paddle dryer Product Overview: This product may be indirect heating of paste, granulated, powdered, slurries or cooling, can complete the drying, cooling, heating, sterilization, reactive, low temperature calcined and other unit operations. The special wedge device stirring Heat Transfer pulp leaves, having a higher heat transfer efficiency and heat transfer surfaces self-cleaning function. The hollow shaft intensive lined with wedge-shaped hollow paddle, heat medium through the hollow axial flow by the blades. The unit effective volume heat transfer area is large, the temperature of the heat medium from -40 ℃ to 320 ° C, can be water vapor, and may be a liquid type: such as hot water, HTF. Indirect conduction heating, air did not carry away the heat, the heat is used to heat the materials. The heat loss is only through the insulation layer of the device body heat to the environment. The wedge-shaped the blades heat transfer surface has a self-cleaning function. The relative motion of the material particles wedge surface produce wash to wash off the wedge surface attachment material, so that the operation has maintained a clean heat transfer surface. The paddle dryer housing Ω, general arrangements for two to four hollow stirring shaft housing. The casing sealed cover with the top cover to prevent leakage of material dust and collect material solvent vapor. At the outlet of setting a block wrench, to ensure that the height of the material level, the heat transfer surface material covering and fully play its role. The heat transfer medium passes through the rotary joint, flowing through the housing jacket and hollow stirring shaft, the hollow stirring shaft according to the heat medium type has a different internal structure, in order to ensure optimum heat transfer effect. Features: 1, blade dryer energy consumption is low: not a lot to carry air heat away due to indirect heating, the dryer outer wall and set the insulation layer, evaporate 1kg of water slurries, only 1.2kg of water vapor. 2, paddle dryer system is low cost: unit effective volume has a huge heat transfer surface, and to shorten the processing time, the equipment size is smaller. Greatly reduced the building area and building space. 3, processing a wide range of materials: using different heat medium, not only to deal with heat-sensitive materials, but also to deal with the required high temperature materials processing. Commonly used medium: water steam, thermal oil, hot water, cooling water, etc.. Application in many areas may also be intermittent operation, can be either continuous operation. Environmental pollution: do not use carrying air, materials and dust entrainment. Material evaporation of the solvent is very small, easy to handle. Contaminated material to be recovered solvent conditions, closed loop can be used. 5, low operating costs: normal operation of the device, only one hour / day? Person. Low-speed agitation and reasonable structure. The small amount of wear, and low maintenance costs. 6, the operation is stable: the wedge blades special compression - expansion stirring action, so that the material particles in full surface contact with the heat transfer, the temperature, humidity, degree of mixing of the material in the axial interval gradient is small, thus ensuring The stability of the process. Applications: paddle dryer has been successfully used in the food, chemical, petrochemical, dyes, industrial sludge, and other fields. Equipment heat transfer, cooling, mixing characteristics can be completed the following unit operations: calcination (low temperature), cooling, drying (solvent recovery), and heating (melting), reaction and sterilization. The stirring blades at the same time the effective volume of the heat transfer surface, the unit is the heat transfer area is increased, shortening the processing time. The wedge-shaped the blades heat transfer surface has self-cleaning function. Compression - expansion of the material mixture evenly mixing function. Material along the axial direction into a "piston flow" motion, in the axial interval, the temperature, humidity, degree of mixing of the material gradient is very small. Heat conducting oil do medium blade dryer completion of the low-temperature calcination. Such as: calcium sulfate dihydrate calcined into calcium sulfate hemihydrate. Sodium bicarbonate into calcined soda ash. Pass into the cooling medium, such as water, the cooled brine can be used to cool. : Cool alkali used in the soda ash industry, paddle, replace the old air-cooled cold alkali machine, saving energy and exhaust gas treatment equipment, reduce operating costs. Sulfate, the device main function, without using hot air, so that the solvent recovery, energy consumption, and the ideal state environmental control is easy to handle. Oxidation of flammable solvent to be recovered, the heat sensitive materials is particularly adapt. Has been widely used in the fine chemical, petrochemical, dye industry.
