■ 原理 principle
◎ 濕物料自加料器連續(xù)地加到干燥器上部*層干燥盤上，帶有耙葉 的耙臂作回轉(zhuǎn)運(yùn)動使耙臂作回轉(zhuǎn)運(yùn)動使耙葉連續(xù)地翻抄物料。物料沿 指數(shù)螺旋線流過干燥盤表面，在小干燥盤上的物料被移送到外緣，并 在外緣落到下方的大干燥盤外緣，在大干盤上物料向里移動并從中間 落料口落入下一層小干燥盤中。大小干燥盤上下交替排列，物料得以 連續(xù)地流過整個干燥器。中空的干燥盤內(nèi)通入加熱介質(zhì)，加熱介質(zhì)形 式有飽和蒸汽、熱水和導(dǎo)熱油，加熱介質(zhì)由干燥盤的一端進(jìn)入，從另 一端導(dǎo)出。已干物料從zui后一層干燥盤落到殼體的底層，zui后被耙葉 移送到出料口排出。濕份從物料中逸出，由設(shè)在頂蓋上的排濕口排 出，真空型盤式干燥器的濕氣由設(shè)在頂蓋上的真空泵口抽出。從底層 排出的干物料可直接包裝。通過配備翅片加熱器、溶劑回收冷凝器、 布袋除塵器、干料返混機(jī)構(gòu)、引風(fēng)機(jī)等輔機(jī)，可提高其干燥的生產(chǎn)能 力，干燥膏糊狀和熱敏性物料，可方便地回收溶劑，并能進(jìn)行熱解和 反應(yīng)操作。
◎ Wet materials are fed continuously to the top drying layer in the drier. they will be turned and stirred continuously by harrows when the harrowÕs arm rotates, the material flows through the surface of the drying plate along the exponential helical line. On the small drying plate the material will be moved to its exterior edge and drop down to the exterior edge of the large drying plate underneath, and will then be moved inward and drop down from its central hole to the small drying plate on the next layer. Both small and large drying plates are arranged alternay so as materials can go through the whole drier continuously. the heating media, which could be saturated steam, hot water or thermal oil will be led into drying plates from one end to other end of the drier. the dried product will drop from the last layer of the drying plate to the bottom layer of the body, and will be moved by harrows to the discharge outlet. the moisture exhausts from materials and will be removed from the moist discharge outlet on the top cover, or sucked out by the vacuum pump on the top cover for vacuum-type plate drier. the dried product discharged from the bottom layer can be packed directly. the drying capability can be raised up if equipped with supplementary devices such as finned heater, condenser for solvent recovery, bag dust filter, return and mix mechanism for dried materials and suction fan etc. solvent in those paste state and heat sensitive materials can be easily recovered, and thermal decomposition and reaction can be also carried out.

■ 特點 FeAtUres
◎ 調(diào)控容易、適用性強(qiáng)
1、通過調(diào)整料層厚度、主軸轉(zhuǎn)速、耙臂數(shù)量、耙葉型式和尺寸可使干 燥過程達(dá)到*。
2、每層干燥盤皆可單獨通入熱介質(zhì)或冷介質(zhì),對物料進(jìn)行加熱或冷卻,物 料溫度控制準(zhǔn)確、容易。 3、物料的停留時間可以精確調(diào)整。
4、物料流向單一，無返混現(xiàn)象，干燥均勻、質(zhì)量穩(wěn)定、不需再混合。
◎ 操作簡單、容易
1、干燥器的開車、停車操作非常簡單。
2、停止進(jìn)料后，傳送物料后耙葉能很快地排空干燥器內(nèi)的物料。
3、通過特殊的大規(guī)格檢視門的視鏡，可以對設(shè)備內(nèi)進(jìn)行很仔細(xì)的清洗 和觀察。
◎ 能耗低
1、 以傳導(dǎo)熱進(jìn)行干燥，熱效率高，能量消耗低。
◎ 操作環(huán)境好，可回收溶劑，粉塵排放符合要求
1、 常壓型：由于設(shè)備內(nèi)氣流速度低,而且設(shè)備內(nèi)濕度分布上高下低,粉塵很 難浮到設(shè)備頂部,所以頂部排濕口排出的尾氣中幾乎不含有粉塵。
2、密閉型：配溶劑回收裝置,可方便地回收載濕氣體中的有機(jī)溶劑。溶劑 回收裝置簡單，回收率高，對于易燃、易爆、有毒和易氧化的物 料，可用氮氣作為載濕氣體進(jìn)行閉路循環(huán)，使之安全操作。特別適 用于易燃、易爆、有毒物料的干燥。
3、真空型：在真空狀態(tài)下操作的盤式干燥器，特別適用于熱敏性物料 的干燥。
◎ 安裝方便、占地面積小
1、干燥器整體出廠，整體運(yùn)輸，只需吊裝就位，安裝定位非常容易。
2、由于干燥盤層式布置、立式安裝，既使干燥面積很大,占地面積也很小。
