Product Details
Overview: The hollow shaft densely arranged wedge-shaped hollow blades, heat medium flows through the hollow shaft blade. The effective volume of heat transfer area is very large, the heat medium temperature from -40 ℃ to 320 ℃, can be water vapor, it can be liquid type: such as hot water, heat conducting oil. Indirect conduction heating, no carrying air to carry heat, heat are used to heat the material. Heat loss is only through the body insulation to the environment of heat. Wedge blade heat transfer surface with self-cleaning function. The relative movement between the material particles and the wedge surface produces a scrubbing action that scrubs the wedged surface attachment material and keeps the clean heat transfer surface in operation. Paddle dryer shell is W-type, the shell is generally arranged two to four hollow mixing shaft. The housing has a sealed end cap and cover to prevent material dust from leaking and collecting solvent vapor. Set a spike at the spout to ensure that the material level height, the heat transfer surface is covered by the material and give full play to its role. Heat medium through the rotary joint, through the shell jacket and hollow stirring shaft, hollow mixing shaft according to the type of heat medium and have different internal structure to ensure the best heat transfer. Application: Paddle dryer has been successfully used in food, chemical, petrochemical, dyes, industrial sludge and other fields. Equipment heat transfer, cooling, stirring the characteristics of the unit to enable it to complete the following operations: calcination (low temperature), cooling, drying (solvent recovery), heating (melting), reaction and sterilization. Stirring blades are heat transfer surfaces at the same time, increasing the heat transfer area within the effective volume of the unit and shortening the processing time. Wedge blade heat transfer surface has a self-cleaning function. Compression - Expansion Stir to mix the material evenly. Materials along the axial into a "plug flow" movement, in the axial interval, the material temperature, humidity, mixing gradient is very small. ● Heat conducting oil as heat medium, paddle dryer to complete the low-temperature calcination. Such as: calcium sulfate dihydrate (Ca2SO4 · 2H2O) calcined into calcium sulfate hemihydrate (Ca2SO4 · 1 / 2H2O). Sodium bicarbonate (NaHCO3) calcined into soda (Na2CO3) and so on. ● Access to cooling medium, such as water, cooling brine can be used to cool. Such as: the use of soda ash industry cooler, instead of the old air cooler cooling machine, saving energy and exhaust gas treatment equipment, reducing operating costs, but also for titanium dioxide, nickel-iron alloy powder and a variety of powder Material cooling. In a single machine can be cooled from 1000 ℃ to less than 40 ℃. ● Drying, the most important function of the equipment, do not use hot air, make solvent recovery, energy consumption, environmental control in an ideal state of easy to handle. The need for solvent recovery, easy to burn flammable and heat-sensitive materials in particular. Has been widely used in fine chemicals, petrochemicals, dyes industry. ● The uniformity of temperature, humidity, and mixing within the axial range allows the equipment to be used to heat or melt, or to perform some solid material reaction. In the fertilizer and modified starch industry have been successfully used. Paddle dryer can be used to sterilize food and flour. Unit effective volume of large heating area, the material will soon be heated to sterilization temperature, to avoid prolonged heating and change the material quality. Adapted 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 , Acrylic resins, engineering plastics, polyvinyl chloride, polyvinyl alcohol, polystyrene, polypropylene, polyester, polyoxymethylene, styrene ~ acrylonitrile copolymer, ethylene ~ propylene copolymer. Environmental Protection Industry: PTA sludge, electroplating sewage sludge, boiler soot, pharmaceutical waste, sugar residue, MSG plant residue, coal ash. Feed industry: Soy sauce residue, bone-based feed, distiller's grains, food scraps, apple pomace, orange peel, soybean meal, chicken feed, fish meal, feed additives, bio-dross food industry: starch, cacao beans, corn kernels, Starch, medicines. Chemical Industry: Soda Ash, NPK Fertilizer, Kaolin, Bentonite, White Carbon Black, Carbon Black, Phosphogypsum, Sodium Fluoride Oxide, Calcium Nitrate, Magnesium Carbonate, Sodium Cyanide, Aluminum Hydroxide, Barium Sulfate, Calcium carbonate, dye, molecular sieve, saponin.
Features: ● Blade dryer low energy consumption: As a result of indirect heating, there is not a lot of carrying air to take away the heat, dryer wall and set the insulation layer, the slurry material, evaporation of 1kg water only 1.22kg water vapor. ● Blade dryer low system cost: unit effective volume has a huge heat transfer surface, it shortens the processing time, the smaller the size of the device. It greatly reduces the construction area and building space. ● Processing a wide range of materials: the use of different heat medium, both heat-sensitive materials, but also deal with the need for high-temperature processing of materials. Common media are: water vapor, thermal oil, hot water, cooling water and so on. Can be continuous operation can be intermittent operation, can be applied in many fields. ● Environmental pollution is small: do not use to carry air, dust material with little. Material solvent evaporation is small, easy to handle. For contaminated materials or solvent recovery conditions, closed-loop can be used. ● low operating costs: the normal operation of the device, only 1-2 people / day. Low-speed mixing and reasonable structure. Low wear, low maintenance costs. ● Stable operation: Due to the special compression-expansion stirring of the wedge blade, the particles of the material fully contact with the heat transfer surface. In the axial section, the gradient of the temperature, the humidity and the mixing degree of the material is very small, thereby ensuring that the process Stability.
