China Kjg Series Hollow Blade Dryer

Product Description

By absorbing foreign advanced technology, based on to improve and optimize the design of the wedge-shaped hollow paddle dryer for paste, granular, powder, paste material indirect heating or cooling , to be completed by drying, cooling, heating, sterilization, reaction, low temperature calcination and other unit operations. Wedge-shaped mixing device in a special heat transfer blade, has a high heat transfer efficiency and heat transfer surface self-cleaning function.
Descriptions:
Densely lined with wedge-shaped hollow shaft hollow blades, heat medium through the hollow axial flow through blades. Unit effective volume of a very large area of heat transfer, heat medium temperature from -40 ºC to 320 ºC, can be water vapor, may also be liquid-type: such as water, oil and so on. Indirect conduction heating, the air does not carry away the heat, the heat are used to heat materials. only through the device body heat loss to the environment, heat insulation layer. Wedge-shaped blades with self-cleaning heat transfer surfaces. Wedge-shaped surface material particles and scrubbing effect relative movement, to wash away the wedge surface material attachments, so in operation have maintained a clean heat transfer surfaces. Blade dryer for the W-type shell, the shell of the general arrangements for 2-4 hollow stirring shaft. Shell with a sealed cover with the cover to prevent dust leakage and collection of materials, solvent vapor materials. Set out and exit pull a block, to ensure a high degree of material level, so that heat transfer surface is covered with full play materials. Heat medium through the rotary joint, passing through the shell jacket and the hollow stirring shaft, hollow shaft stirring according to the type of thermal media have different internal structures to ensure the best heat transfer.
Applications:
Blade dryer has been successfully used in food, chemical, petrochemical, dye, industrial sludge and other fields. Equipment heat, cooling, mixing features make it to complete the following unit operations: calcination (low temperature), cooling, drying (solvent recovery), heating (melting), response and sterilization. Mixing blades at the same time the heat transfer surface, the effective volume per unit area of heat transfer increases, reducing the processing time. Heat transfer surfaces in wedge-shaped blades with self-cleaning function. Compression - Expansion mixing features make the material mixed uniformly. Material along the axis into a "plug flow" movement, in the axial zone, the material temperature, humidity, mixing a very small degree of gradient.
Conducting oil to do with the heat medium, blade dryer to complete the work of low-temperature calcination. Such as: calcium sulfate dihydrate (Ca2SO4 · 2H2O) calcined into calcium sulfate hemihydrate (Ca2SO4 · 1/2H2O). Sodium bicarbonate (NaHCO3) into calcined soda (Na2CO3) and so on.
Pass into the cooling medium, such as water, salt, etc. can be used to cool the cooling. Such as: use of soda ash industry in blade-type cooler base machine to replace the old air-cooled cooler base machine, saving energy and exhaust gas processing equipment, lower operating costs, but also for titanium, nickel alloy powder and all kinds of powder granular materials cooling. On a single machine where the material can be cooled from 1000 ºC to less than 40 ºC.
Dry, the main function of equipment, do not use hot air to solvent recovery, energy consumption, environmental control is easy to deal with the ideal state. On the need to recover solvents, heat-sensitive materials, particularly flammable adapt easily oxidized. Has been widely used in fine chemical, petrochemical, dye industry.
Axial range, temperature, humidity, mixing degree of uniformity, so equipment can be used to heating or melting, or some solid material response. In the compound and modified starch industries have been successfully used. Blade dryer can be used to carry out sterilization of food and flour. Unit within the effective volume of a large heating area, will soon be material heated to sterilization temperature, to avoid prolonged heating change the quality of materials.
Adaptation of materials
Petrochemical Industry: polyolefin powder, polycarbonate resin, high and low density polyethylene, linear low density polyethylene, polyacetal particles, nylon 6, nylon 66, nylon 12, cellulose acetate, polyphenylene sulfide, propylene base resin, engineering plastics, polyvinyl chloride, polyvinyl alcohol, polystyrene, polypropylene, polyester, polyoxymethylene, styrene ~ Acrylonitrile, ethylene propylene copolymer ~.
Environmental protection industry: PTA sludge, electroplating sludge into the water, boiler ash, pharmaceutical waste, sugar residue, glutamate factory waste, coal ash.

Food industry: starch, cocoa beans, corn kernels, salt, modified starch, pharmaceuticals.
Chemical industry: soda ash, NPK fertilizer, kaolin, bentonite, white carbon black, carbon black, phosphorus gypsum, oxidation of sodium fluoride, calcium nitrate, magnesium carbonate, sodium cyanide, aluminum hydroxide, barium sulfate, sulfuric acid , calcium carbonate, dyes, molecular sieve, saponin.
Features:
Blade dryer energy consumption is low: as indirect heating, the air does not carry away a lot of heat insulation of dryer wall has, on the slurry material, evaporation of 1kg of water vapor only 1.22kg.
Blade dryer system costs low: within the effective volume of units have a large heat transfer surface, the reduced processing time, equipment size becomes smaller. Would greatly reduce the building area and building space.
Dealing with a wide range of materials: using a different hot medium, able to deal with heat-sensitive materials can be heat-treated materials handling. Commonly used media are: water, steam, oil, hot water, cooling water. Continuous operation can also be intermittent operation can be applied in many fields.
Environmental pollution: do not carry air, dust entrainment few materials. Solvent evaporation material is very small, easy to handle. To have contaminated materials or be recycled solvent conditions, can be used closed circuit.
Low operating cost: the equipment normal operation, only 1 hour / Heaven. Low speed and reasonable structure. Wear a small, very low maintenance costs.
Operation stability: As the wedge-shaped blades of special compression - expansion of stirring, so that material particles sufficient surface contact with the heat transfer in the axial zone, the material temperature, humidity, mixed density gradient is very small, thus ensuring the process stability.
