The flash dryer is driven by hot air tangents into the bottom of the dryer, forming a powerful rotating wind field under the stirrer. Material by a spiral feeder into the dryer, under the strong function of the high-speed rotating impeller, the material by the impact, friction, and dispersion under the action of shear force which block material quickly shattered, and a good contact with the hot air, heat, and dry. The dry material is carried into the dust collecting system for collection and treatment, which is in accordance with the environmental requirements. The exhaust gas of 50mg/m3 is discharged by the fan, and the whole drying process is completed.
Flash dryer is a new continuous drying equipment that sets dry, pulverized and sieving. It is especially suitable for drying of cake, paste and slurry materials. In the tower of dry wet material drying time was only about 5-8 seconds, moisture evaporating, drying the product quality and drying temperature, wind speed, air volume, has broken rate, jiangyin is mechanical creative design, adjustable flash drying the tangent into the wind, the adjustable discharging finished product particle size, final moisture content.
Heater, feeder, mixing and crushing system, classifier, drying director, cyclone separator, cloth bag dust collector, fan, etc.
The working principle of
Hot air from the entrance at the bottom of the tube into the drying chamber in the tangent direction of the gaps, and spiral rising, at the same time, the material by quantitative join tower, feeder and sufficient heat exchange with the hot air, is bigger than the wet material under the action of stirrer is mechanical crushing, moisture content is low and the smaller the particle size, the material rise, together with rotating airflow conveying to the separator for gas-solid separation, product packaging to collect, and tail gas emptying treated with dust removal device.
1 week in drying chamber to the high gas velocity, the material stay time is short, to effectively prevent and metamorphic thermal sensitive material of wall material viscosity, and can be a dry into uniform powder products, eliminating the classification of crushing and screening process.
2. The drying chamber is equipped with graded rings and swirl films. The fineness of the material and the final moisture can be adjusted. The special wind device reduces the resistance of the equipment and effectively increases the drying uniformity of the material.
A special cooling device and air pressure seal are installed at the bottom of the dryer to avoid the deterioration of the material at the bottom of the dryer.
4. It can effectively control the final moisture and fineness, and ensure that the moisture content and fineness of the products are uniform and uniform through the adjustment of the feeding, hot air temperature and classifier.
For the material
Paste, slurry, filter cake and other materials, plate frame pressure filter or centrifuge dewatering materials. Such as:
1 inorganic class: boric acid, calcium carbonate, hydroxide, copper sulfate, iron oxide, barium carbonate, trioxide antimony, various metal hydride, various heavy metal salts, synthetic cryolite, etc.
Organics: atrazine, lauric acid separation, benzoic acid, benzoic acid, bactericidal, sodium oxalate, cellulose acetate, etc.
3 ceramic: kaolin, silicon oxide, clay, etc.
4 dyes: anthraquinone, black iron oxide, indigo pigment, butyric acid, titanium oxide, zinc sulfide, various azo dye intermediates.
5. Food: soy protein, gelatine and starch, alcohol, wheat, wheat starch, etc.
