Introduction:
Rotary Dryer can drying livestock manure moisture content upto 30-50% to safety store moisture level. The whole process is seal.reduce the pollutiong for environment.Material were uniform-dispersed in the rotating drum,full contact with hot air.To speed up the drying heat transfer,mass transfer Rotary dryer with high degree of mechanization,high production capacity.can keep continuous working.Excellent structure,Simple,stable performance;Less failure,low maintenance cost,lowpower consumption.Widely used with excellent uniformity of drying effect.
The dryer uses self-made combustible gas as the heating source, and the drying is divided into two parts: drum part and serpentine tube part. Roller part: inner roller and outer insulation. The inner drum is equipped with three inner spiral plates, which can make the drying materials move evenly, which is called stir frying heating. The serpentine pipe uses heat source for secondary use, and uses the negative pressure air suction of induced draft fan to pump the drying materials into the spiral for separation, so as to achieve the drying effect. The existing air dryer generally uses coal and firewood as heat source. It is characterized by high labor intensity, high cost, high thermal efficiency loss and less than 30% heat utilization. Generally, the original half bucket with 35% water content needs 3-4 times drying, while the gas drum dryer can dry raw materials with 35% sweat rate at one time. It can save electricity by 75% and greatly reduce the drying cost. The gas source of the dryer is from the carbonization kiln, and the methane gas produced by carbonization of the kiln is used by the dryer.
Working principle:
The drum dryer is mainly composed of rotary body, lifting plate, transmission device, support device and sealing ring. The dryer is a cylinder slightly inclined to the horizontal direction. The materials are added from the higher end, and the high-temperature hot flue gas flows into the cylinder body together with the material. With the rotation of the cylinder, the material moves to the lower end due to gravity. In order to increase the drying rate and promote the material to move forward, a plate is installed on the inner wall of the cylinder to pick up and sprinkle the materials, so as to increase the contact surface between the material and the air flow. The dried product is collected from the lower part of the bottom end.
Advantage:
1. Drying mechanization is high, production capacity is large, and continuous operation is possible.
2. The structure is excellent and simple, the material runs smoothly through the cylinder resistance, and the operation is convenient.
3. Less faults, low maintenance cost and low power consumption.
4. The uniformity of product drying is good.
5. The bean dregs drying production line adopts a special dispersing device to ensure the drying effect of the dryer.
6. The new and unique sealing device, combined with a good insulation system, effectively reduces the coal consumption of the drying system.
