三筒烘干機(jī)是引進(jìn)歐洲先進(jìn)技術(shù)，由三個(gè)不同直徑的同心圓筒彼此相嵌組合而成的。筒內(nèi)裝有不同角度和間距的揚(yáng)料板和導(dǎo)料板，這種結(jié)構(gòu)能夠保證被烘干物料在重力作用下沿著螺旋的運(yùn)動(dòng)方向運(yùn)動(dòng)，在筒內(nèi)保持足夠的停留時(shí)間和充分的分散度，使被烘干物料在筒內(nèi)與來自熱風(fēng)爐內(nèi)的熱氣流進(jìn)行充分的熱交換。特殊的三筒結(jié)構(gòu)，使內(nèi)筒和中筒被外筒包圍而形成了一個(gè)自身保溫系統(tǒng)，內(nèi)、中筒體表面散發(fā)的熱量參與到外一層筒內(nèi)物料的熱交換，而外筒又處在熱氣流的低溫端，所以筒體的散熱面積和熱能損失明顯降低。該機(jī)用于烘干黃砂、礦渣、粘土、石英砂等原材料，廣泛應(yīng)用于干混砂漿、水泥、建材、玻璃、化工、鑄造等行業(yè)。

　　The three-cylinder dryer adopts the advanced technology introduced from Europe; the dryer is assembled by three concentric-cylinders which halved together with different diameters. Feed aprons and stock guide plates with different angles and spacing are being equipped inside the cylinder, the structure can ensure that the material being dried runes along the direction of screwing under the impact of gravitation and keeps for a sufficient maintaining times and dispersity in the cylinder to make the material has sufficient heat exchange with the heat airflow from air heating furnace inside of the cylinder. The special three-cylinder structure makes the inner cylinder and median cylinder being surrounded by the outer cylinder to form a self contained thermal insulation system, the heat set out by inner and median cylinders surfaces participates the heat exchange of materials in outer cylinder, however the outer cylinder is being located in the low temperature end of the heat airflow, so the heat dissipation area and heat losses are being reduced significantly. The machine can be applied in drying of raw materials such as yellow sand, slag, clay, quartz sand etc., and widely used in industries such as dry mortar, cement, building materials, glass, chemicals, and casting etc.

　　◎ 三筒烘干機(jī)能充分利用余熱，減少散熱損失，增大熱交換面積，使烘干機(jī)的單位容積蒸發(fā)強(qiáng)度得到大大提高，從而有效地提高了熱能利用率，降低了能耗，使三筒烘干機(jī)的熱效率得到較大幅度的提高。與相同效率的單筒烘干機(jī)相比，熱效率提高50%左右，節(jié)約能耗一倍以上。

　　◎ 由于三筒烘干機(jī)筒體的長(zhǎng)度是單筒烘干機(jī)的三分之一，基礎(chǔ)面積比單筒烘干機(jī)節(jié)約60%左右，基礎(chǔ)投資相應(yīng)降低。

　　◎ 烘干機(jī)采用托輪與輪帶的摩擦傳動(dòng)，傳動(dòng)功率低，降低了設(shè)備工作時(shí)的噪音。

　　◎ 烘干機(jī)筒體密封系統(tǒng)采用了微接觸技術(shù)，密封效果更佳，減少了粉塵污染。

　　◎ 烘干機(jī)筒體和揚(yáng)料板均采用合金鋼板制造，比普通鋼板壽命提高一倍以上。

　　◎ 三筒烘干機(jī)可適應(yīng)煤、油、氣等多種燃料，能烘干塊狀、粒狀、粉狀等多種物料，符合國(guó)家環(huán)保政策、是替代 傳統(tǒng)烘干設(shè)備的環(huán)保節(jié)能型產(chǎn)品。

　　◎ Three-cylinder dryer can take full advantage of excess heat, reduce heat loss and increase the heat exchange area, making the unit evaporation intensity of the dryer greatly improved, thereby effectively improving the heat energy utilization rate, reducing the energy consumption and making the heat efficiency of three-cylinder dryer improved in a wider range. Compared with single-cylinder dryer with the same efficiency, its heat efficiency is improved about 50% and energy consumption saving doubles.

　　◎ Because the cylinder length of the three-cylinder dyer is one third of single-cylinder dryer and the base area saves about 60% than the single-cylinder dryer, the base investment is reduced correspondingly.

　　◎ The dryer drives by adopting the friction between supporting roller and belting leather, and the transmission power is low, thereby reducing the noises when the equipment working.

　　◎ The cylinder sealing system of the dryer adopts micro-contact technology, with better sealing effect and reducing the dust pollution.

　　◎ The cylinder and raising material board of the dryer both adopt alloy steel plates, and double the service life than common steel plates.

　　◎ Three-cylinder dyer can apply to coal, oil, gas and various fuels and parch lump, granular, powder and various materials, which complies with the national environmental-friendly policy and is the environmental-friendly and energy consumption product that can replace tradition drying equipment
