The working principle of the three-cylinder dryer
The advantages of the three-cylinder dryer
The dryer is scientific, reasonable, efficient and energy-saving. The heat exchange between the material and the hot air flow in the inner cylinder is conducted in the form of radiation, convection and conduction, and the heat exchange in the outer cylinder is conducted in the form of conduction and convection. The dryer has high thermal efficiency and significant energy saving effect. After testing, the thermal efficiency is much higher than that of traditional dryers. After the equipment was put into operation, the coal-saving effect was remarkable.
This machine adopts the co-current drying process of materials and hot air, and has a wide range of applications. It is suitable for drying various raw materials such as clay, coal, slag, iron powder, etc., and is also suitable for drying various bulk materials in metallurgical and chemical industries. Compact structure. The whole machine is arranged horizontally and supported by supporting wheels. The large and small gear transmission is eliminated and replaced by supporting wheel transmission, making the equipment installation more convenient, operation simpler, operation more reliable and operation rate higher.
The external surface area of this machine is much smaller than that of a single-cylinder rotary dryer, and the outer cylinder has a thermal insulation effect on the inner cylinder. The surface temperature of the outer cylinder is low and the heat loss is less. It is highly energy-saving and greatly improved. improve the working environment and working conditions.
A variety of lifting plate designs, the organic combination of the angular lifting plate and the multi-shaped lifting plate make the exchange of materials and hot flue gas more complete and reduce the mechanism of wind tunnel in the dryer barrel.
Adopt frequency conversion speed regulation to adjust the cylinder speed. According to the moisture entering the machine and the output requirements, the appropriate speed is adopted to ensure that the needs of the next process are met. Automatic temperature monitoring system makes operation more convenient.
