一、工作原理及應用范圍介紹 

Introduction of Working Principle and Scope of Application

物料從進料口進入床體內，床體振動電機或其他方式提供的激振力作用下作一定頻率的振動,先經過濾凈化然后經加熱到一定溫度后的熱空氣經入風口進入干燥機下風分配室然后再均勻穿過流化床板，物料在振動分散力和經空氣分布板均風的熱氣流雙重作用下，呈懸浮狀態與熱氣流接觸，物料顆粒與熱介質之間進行著激烈的湍動，使傳熱和傳質過程得以強化，干燥后的產品由排料口排出，蒸發出的水份和廢氣經旋風分離器回收粉塵后，排入大氣。下床體為床層提供了一個穩定的具有一定壓力的風室。調節引風機，使上箱體中床層物料上部保持微負壓，維持良好干燥環境并防止粉塵外泄。

振動流化床干燥機用于顆料狀、粉末狀物料干燥的新型流態化高效干燥設備，適用于化工、制藥、食品、脫水蔬菜、糧食、礦產等行業。也可以用于物料冷卻、增濕作業。該機組能大批量、長期連續的進行生產。節能型振動流化床

            Material enters the bed via the feed opening and vibrates at a certain frequency under the exciting force provided by the vibration motor of bed or in other way; the hot air which is filtered and purified firstly and subsequently heated to a certain temperature enters the drier downwind distribution chamber via the air intake vent and subsequently runs through the fluidized bed plate. Under the dual action of the vibration dispersion force and the hot air distributed uniformly by the air dispersion plate, the material in the suspending state contacts with the hot air. The drastic turbulence between the material particles and the heat media enhances the heat and mass transfer process. The products dried are discharged via the discharge opening; water and waste gas are discharged to the atmosphere after dust is collected by the cyclone separator. The lower bed provides a stable air chamber with stable pressure for the material layer. Induced draft fan is adjusted to maintain tiny negative pressure at the top of the material in the upper box so as to keep a good and dry environment and prevent dust from escaping. The vibro fluidized dynamic drier is a novel fluidized high-efficiency drying equipment used for drying pelletized and powder-like materials. It is suitable for such industries as chemical engineering, pharmaceuticals, food, dehydrated vegetables, grains and minerals, and also suitable for material cooling and humidification operation. This unit can be put into mass and long-period continuous production.

二、特點Characteristics

1.物料受熱均勻，熱交換充分，干燥強度高，比普通干燥機節能30%左右。

2.可調性好，適應面寬，料層厚度和在機內移動速度以及全振幅變更均可實現無級調節。

3.振動源是采用振動電機驅動,運轉平衡、維修方便、壽命長。

4.振動有助于分散濕含量大、易團聚、粘結的顆粒，改善流化狀態，流態化穩、均勻，無死隙和吹穿現象，可以獲得均勻的干燥、冷卻、增濕效果。

5.對顆粒物的破碎以及磨損較少，可用于易碎的干燥，物料顆粒不規則時亦不影響工作效果。

6.由于施加振動，可使最小流化氣速降低，因而可顯著降低空氣需求量，進而降低粉塵層夾帶，配套熱源，風機，旋風分離器等也可相應縮小規格。

1.The material is heated evenly with sufficient heat exchange and high drying intensity. Its energy saving is 30% higher than the ordinary driers.

2.It has great adjustability and wide applicability. The thickness of material layer, the running speed in the drier and the change of double amplitude are step-less controllable.

3.Vibration is driven by the vibration motor featured by smooth operation, easy to repair and long service life.

4.Vibration is helpful to disperse the particles which have high moisture content and are easy to clot and cohere and improving the fluidized state, so that fluidization is stable and uniform, without dead space and blow-through, and uniform drying, cooling and humidification effects can be achieved.

5.It may make less particles crushed and abraded and can be used to dry the fragile particles. Its operating effect will not be affected even the particles of material are regular.

6.Vibration can reduce the minimum fluidizing air velocity, so the demａnd for air may decrease obviously and therefore dust entrainment will decrease. The sizes of supporting heat source, fan and cyclone separator etc may decrease accordingly.
