The three-cylinder dryer is an effective energy-saving product improved on the basis of the single-cylinder rotary dryer.
The rotary three-cylinder dryer improves the internal structure of the original single-cylinder dryer, increases the pre-drying of the wet material before entering the machine, and prolongs the drying time of the wet material in the machine, plus sealing, insulation and reasonable supporting measures to Compared with the original single-cylinder dryer, the production capacity of the dryer is increased by 48-80%, the evaporation intensity per unit volume can reach 120-180kg / m3, and the standard coal consumption is only 6-8kg / t. Its advanced technology, reasonable operating parameters and simple and feasible operation are widely used in slag, clay and coal in various industries.
Advantages of three-cylinder dryer:
1. The dryer is scientific and reasonable, efficient and energy saving. The material performs heat exchange with the hot airflow in the form of radiation, convection and conduction in the inner cylinder, 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 greatly exceeds the level of about 50% of the traditional dryer. After the equipment is put into use, the coal saving effect is remarkable.
2. The machine adopts the material and hot air drying process in a co-current manner, which has a wide application range. It can adapt to the drying of various raw materials such as clay, coal, slag, iron powder, etc., and is also suitable for drying various bulk materials in metallurgy, chemical and other departments. Compact structure. The whole machine is horizontally arranged and supported by supporting wheels, eliminating the gear transmission. It is replaced by supporting wheels to make the installation more convenient, simpler operation, more reliable operation and higher operating rate.
3. The external surface area of the machine is reduced by more than 30% than that of the 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 small. The working environment and working conditions.
4. A variety of lifting plate designs. The combination of the angular lifting plate and the 4D lifting plate makes the material and hot flue gas exchange more sufficient, and reduces the mechanism of "wind tunnel" in the dryer barrel.
5.Adopt frequency conversion speed regulation, adjust the barrel speed, according to the moisture and output requirements of the machine, use the appropriate speed to ensure that the needs of the next process are met. Automatic temperature monitoring system makes operation more convenient.
