The rotary three-cylinder dryer is an efficient and energy-saving product improved on the single-cylinder rotary dryer. It has been applied by many companies and industries and has achieved good results. The rotary three-cylinder dryer improves the internal structure of the original single-cylinder dryer, increases the pre-drying of wet materials before entering the machine and extends the drying time of wet materials in the machine, plus sealing, insulation and reasonable supporting measures, so that Compared with the original single-cylinder dryer, the dryer production capacity is -, the evaporation intensity per unit volume can reach -/3, and the standard coal consumption is only -/. The three-cylinder dryer has advanced technology, reasonable operating parameters, and simple and feasible operation. It can be widely used in slag, clay, coal, iron powder, ore powder and other mixed materials in various industries, dry mixed mortar, yellow sand, etc. in the construction industry and Drying of raw materials in chemical industry, casting and other industries.
Advantages and characteristics of the second and three-cylinder dryers:
The dryer is scientific, reasonable, efficient and energy-saving. The material in the inner cylinder exchanges heat with the hot air flow in the form of radiation, convection, and conduction, and the heat exchange in the outer cylinder uses both 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. It is also suitable for drying various bulk materials in metallurgy, chemical industry and other departments. Compact structure. The whole machine is arranged horizontally and supported by supporting wheels. The large and small gear transmission is canceled and replaced by supporting wheel transmission, which makes the equipment installation more convenient, operation simpler, operation more reliable and operation rate higher.
The external surface area of the machine is reduced by more than 3% compared with 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. While being efficient and energy-saving, it greatly Improved working environment and working conditions.
, Various lifting plate designs, the organic combination of angular lifting plate and swastika lifting plate make the exchange of materials and hot flue gas more complete, and reduce the mechanism of wind tunnel in the dryer barrel.
Use variable frequency speed regulation to adjust the cylinder speed. According to the moisture content in 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.
3. The working principle of the three-cylinder dryer:
The material enters the inner layer of the rotary drum from the feeding device to realize downstream drying. The material is continuously picked up and scattered under the lifting plate on the inner layer. Heat exchange is realized in a spiral traveling manner. The material moves to the other end of the inner layer and enters the middle layer for counter-current drying. The material is continuously and repeatedly lifted up in the middle layer in a two-step forward and one-step forward manner. The material is fully absorbed in the middle layer. The heat emitted by the inner roller absorbs the heat of the middle roller, and at the same time prolongs the drying time, and the material reaches the optimal drying state here. The material travels to the other end of the middle layer and falls into the outer layer. The material travels in a rectangular multi-circuit manner in the outer drum. The material that has reached the drying effect travels quickly and is discharged from the drum under the action of hot air. The wet material that has not reached the drying effect cannot be quickly discharged due to its own weight. Traveling, the materials are fully dried in this rectangular lifting plate, thereby completing the drying purpose.
Four: The main features of the three-cylinder dryer:
The investment required for the equipment is that of imported products from abroad.
The final moisture content of the materials is ensured. The following are the preferred products for dry-mixed mortar and slag powder production lines.
The thermal efficiency of the cylinder's self-insulation is as high as above (the thermal efficiency of traditional single-cylinder dryers is only 3), improving the thermal efficiency by 3.
The fuel can be adapted to coal, oil and gas. It can bake the following block materials, granular materials and powdery materials.
Compared with single-cylinder dryers, it occupies about 10% less space, reduces civil construction investment, and reduces power consumption.
, the desired final moisture index can be easily adjusted according to user requirements.
, the outlet air temperature is low, and the dust removal equipment has a long service life.
, no need for large and small gear transmission, using supporting wheel transmission.
The three-cylinder dryer has a compact structure, simple structure, and reasonable layout. It can improve the heat exchange rate between materials and heat energy, so that the material drying effect is good and the basic investment is low. It is only the second-largest single-cylinder dryer with the same output. One-time investment is reduced, and the operation is reliable, with low energy consumption and high thermal efficiency. At the same time, it is easy to realize automated control, reduce operators, and save labor resources.
5. Three-cylinder dryer drying application range:
The three-cylinder dryer is mainly used to dry granular materials within a certain humidity and particle size range. Such as yellow sand, molding sand, slag, cinder, small-grained clay, and other small-particle materials that are not afraid of high temperatures and smoke. The moisture content of the dried material can reach below.
