Rotary flash dryer is a vertical dryer with rotary crushing device, which can complete drying, crushing, grading and other operations of materials at the same time. It is a continuous drying equipment specially designed for drying cake, paste and slurry materials.
Working principle
The clean hot medium heated by the heat source enters the drying chamber in the form of tangents and forms a strong vortex type rotating air flow together with the mechanical stirring mechanism. The wet material is added to the drying chamber quantitatively by the feeder, and is crushed and dried under the action of stirring and eddy airflow.
The top of the drying chamber is provided with a particle size classifier, and the fine powder that meets the drying requirements is discharged from the top of the tower and collected by the separator behind. The larger particles that do not meet the drying requirements are blocked by the classification ring and returned to the drying chamber and continue to be crushed and dried until they are dried into qualified products, which are discharged with hot air and collected by the separator. Clean tail gas is emptied under the action of induced draft fan.
Performance characteristics
1, due to the material by centrifugal, shear, collision, friction and particles are highly dispersed state and the relative speed between solid and gas is larger, strengthen the mass and heat transfer, make the machine high production intensity.
2, dry gas into the bottom of the dryer, produce strong rotating air flow, produce strong erosion of the material on the wall, eliminate the phenomenon of sticking to the wall.
3. In the high temperature area at the bottom of the dryer, heat-sensitive materials do not directly contact with the hot surface, and special devices are installed to solve the problem of coking discoloration of heat-sensitive materials.
4, due to the high circumferential gas velocity in the drying room, the material residence time is short, to achieve high efficiency, rapid, small equipment, large production
5. The upper part of the drying chamber is equipped with ceramic analysis ring and swirl sheet, which can control the particle size and humidity of the outlet material, so as to meet the requirements of the final moisture particle size of different materials.
6, the use of double duct tangential air inlet, avoid the rotation field in the radial flow field velocity uneven.
7, effectively control the final moisture and fineness, through the coordination and unification of the swirl sheet and air inlet speed to control.
8, the rotary blade layout structure is unique, with small wear, wide contact surface, cutting force and so on.
9, good at dealing with heat-sensitive materials, the bottom of the main engine belongs to the high temperature area, the area has high gas velocity and high cooling water protection device, to avoid the possibility of material coking discoloration.
10, the system resistance is small, high thermal efficiency, good operating environment, low labor intensity.
11, the main engine with a new sealing structure, the main engine bearing life cycle extension and bearing seat with water jacket circulating cooling device.
Adaptive material
Calcium carbonate, hydroxide, copper sulfate, ferric oxide, barium carbonate, antimony trioxide, all kinds of metal hydroxide, all kinds of heavy metal salts, synthetic cryonite, etc.
