回轉滾筒干燥機
一、工作原理及應用范圍介紹 Introduction of Working Principle and Scope of Application
需干燥的物料經加料器輸送到回轉圓筒干燥機的進料端。物料從較高一端加入，熱載體可由低端進入與物料呈逆流熱交換形式；也可以設計為熱載體與物料并流進入筒體內。干燥筒體轉動，物料在重力作用下運行到較低的一端，濕物料在圓筒內向前移動過程中，與熱空氣進行傳熱傳質，從而達到干燥之目的，被干燥的物料從出料端送出。在圓筒內裝有各種形式的抄板（抄板形式、結構是依物料特性的不同而不同）其作用是把物料抄起來灑下，形成料幕，使物料與氣流的接觸表面增大，以提高干燥速率并促進物料前進。尾氣經旋風分離器將氣體內所帶物料捕集下來。如需進一步減少尾氣含塵量，可設置袋式除塵器或水浴除塵器除塵后排放。
回轉圓筒干燥機是一種連續處理大批量物料的干燥設備，廣泛應用在各種散粒物料的干燥，現已發展到應用于溶液及膏狀物料的干燥上。運轉可靠，操作彈性大，適應性強，處理能力大，物料的適應性強，現廣泛應用于各行業，如：
1. 化工、礦工、冶金等行業：礦石、礦渣、煤、金屬粉末、粘土、硅藻土、高嶺土。
2. 農業、飼料、肥料行業：秸稈、牧草、樹葉、魚粉、玉米醬、淀粉渣、酒糟、藥渣、果渣、醬油渣、甘蔗渣、草炭、有機復合肥、污泥、水產品廢料、食品廠廢料、屠宰廠廢料、有機肥料、無機肥料、磷肥硫銨。
3. 對有特殊要求的粉狀、顆粒狀物料干燥。
4. 如各種結晶體、輕質碳酸鈣、活性白土、磁粉、石墨、無機泥漿、陶土、石灰漿、礦石泥漿、磷礦渣、鋁廠赤泥。
5. 要求低溫干燥，且需要大批量連續干燥的物料。
The materials to be dried shall be conveyed to the charge end of rotary drum drier via the feeder. The materials shall be charged from the relatively high end, and the heat carrier can enter from the relatively low end to present a counter-current heat exchange form together with the materials; it also can be designed as heat carrier and materials entering into the drum in cocurrent flow. The drier drum rotates, the materials move to the relatively low end under the action of gravity, the wet materials conduct heat and mass transfer with heat air in the process of moving forward in the drum, thus to reach the purpose of drying, and the materials that have been dried will be delivered from the discharge end. The drum is installed with various types of shovelling plates (according to different characteristics of materials, types and structures of shovelling plates are different), which shovels and sprays the materials to form a materials curtain to increase the contact surface between the materials and the airflow to improve the drying rate and promote the materials moving ahead. The end gas catches the materials carried by air via a cyclone separator. If it is necessary to further reduce the dust content of end gas, a bag filter can be set up or dust shall discharged after dust is removed with a wet dust collector.
Rotary drum drier is a kind of drying unit for continuous processing of materials in large batches, which is widely used for drying for various granular materials. Now it has been developed for drying of solution and paste materials. With reliable operation, large operation flexibility, strong adaptability, large processing ability, and strong adaptability to various materials, now it is widely used in various industries, for example:
1. Chemical, miner and metallurgical industries: ore, slag, coal, metal powder, clay, kieselguhr and kaolin.
2. Agricultural, feed, fertilizer industries: straw, pasture, leaves, fish meal, corn sauce, starch residue, vinasse, herb residue, lees, medical, pomace, soy sauce residue, bagasse, peat, organic compound fertilizer, sludge, waste of aquatic products, waste of food factory, waste of the abattoir, organic fertilizer, inorganic fertilizer, phosphate fertilizer ammonium sulphate.
3. Drying of powdery and granular materials with special requirements.
4. Various crystalline solids, light calcium carbonate, activated clay, magnetic powder, graphite, inorganic mud, argil, lime slurry, ore slurry, phosphor slag and aluminum plant red mud.
5. Materials requiring low temperature drying and continuous drying in large batch.
二、特點Characteristics
1.干燥機處理能力大，燃料消耗少，干燥成本低，系連續不間斷的大批量的烘干裝置。
2.結構簡單，操作方便 , 清掃容易。
3.故障少，設備維護費用低。
4.適應范圍廣，可以用于處理顆粒狀物料與各種流動性相對比較好一點的物料的脫水烘干。
5.操作彈性大,可擴展能力強，產能適應性強，即使產量小幅度增加，也無需更換設備。
1. With large processing capacity, less fuel consumption and low drying cost, the drier is a drying unit for continuously drying in large batch.
2. It is of simple structure, convenient for operation and easy to clean.
3. It has less troubles and low equipment maintenance costs.
4. It has wide scope of application , and it can be used for dehydration and drying of granular materials and various materials with relatively good liquidity.
5. With large operation flexibility, strong expandable ability and strong capacity adaptability, it is not necessary to replace the drying unit even if the output increases slightly.
