Zhengzhou Qunzhi Mechanical Dryer Manufacturer
As one of the leaders of dryers, we have the courage to persist and make unremitting efforts to realize a new, high-efficiency and energy-saving three-cylinder dryer. How to use the dryer? The drying efficiency of the dryer depends to a large extent on the quality of the combustion chamber. Therefore, during the operation of the dryer, special care must be taken on the combustion chamber, blower and dust removal equipment. Notice. One hour before starting the dryer, ignite the stove and check that all ancillary equipment, including the transmission parts of the dryer, support and trailer parts, etc., are tight, normal, smooth, and reliable before driving. Before lighting the furnace, check the furnace, grate, feeding device, combustion chamber, slag in the furnace pit, furnace door, air duct, regulating valve, blower, dust collector, etc. Before starting the dryer, check the fuel, tools, transmission support device and lubricate all bearings and friction surfaces.
Working principle of three-cylinder dryer
The material enters the inner layer of the rotary drum from the feeding device to achieve downstream drying. The material is continuously picked up and scattered under the lifting plate in the inner layer in a spiral traveling pattern. To achieve heat exchange, 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-back motion. The material in the middle layer fully absorbs the radiation emitted by the inner drum. It absorbs the heat of the middle drum and prolongs the drying time. The material reaches the best 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. 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 only one-half of a single-cylinder dryer with the same output. It reduces the one-time investment and has reliable operation, low energy consumption and high thermal efficiency. At the same time, it is easy to realize automatic control, reduce operators and save labor resources.
The advantages of the three-cylinder dryer
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 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 efficient and energy-saving at the same time. 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.
