設備簡介Equipment Introduction

LMZL型直線振動流化床干燥機采用振動電機產生的激振力的機理，而使干燥于流化床床面的被干燥物料，能在干燥過程中有序地向前推進直至出料。在生產工藝過程中，物料干燥在全封閉的狀態下完成，由此減少物料交叉污染和人物流污染。直線振動流化床干燥技術不僅實現了動態干燥，較傳統的烘箱、真空等靜態干燥輻射傳熱，提高熱效率、減少工藝環節、縮短生產周期、降低能源消耗，而且可連續生產，達到產業化生產規模。振動流化床由于應用風動力學和動力學熱物理原理，使物料在干燥中，由于激振力的作用，使物料能達到自轉和頻率激振率的相互碰撞摩擦，不僅加速了物料內部含濕份向表面轉移，而且物料的自轉運動，可使全方位受熱傳質熱交換，克服輻射單向傳熱因物料受熱不均，而產生成品質量問題。

The LMZL linear vibration fluidized bed dryer adopts the mechanism of excitation force generated by the vibration motor, which enables the dried material on the fluidized bed to move forward in an orderly manner until discharge during the drying process. In the production process, material drying is completed in a fully enclosed state, thereby reducing cross contamination of materials and human flow pollution. The linear vibration fluidized bed drying technology not only achieves dynamic drying, but also improves thermal efficiency, reduces process steps, shortens production cycle, and reduces energy consumption compared to traditional static drying methods such as ovens and vacuum. It can also achieve continuous production and achieve industrial production scale. Due to the application of principles of aerodynamics and dynamic thermophysics, vibrating fluidized beds enable materials to achieve collision and friction between rotation and frequency excitation rates during drying. This not only accelerates the transfer of moisture content inside the materials to the surface, but also enables all-round heat transfer, mass and heat exchange, overcoming the quality problems of finished products caused by uneven heating of materials due to radiation unidirectional heat transfer.

工作原理operational principle

本干燥機的工作原理是應用振動電機產生的激振頻率，使置于橡膠彈簧上的流化床主機由于激振頻率而產生有規律的振動，在正常空載運轉的狀態下，由流化床一端的加料器投料，被干燥物料進入干燥室，即流化床床面，經中效、高效過濾后的加熱空氣由流化床底部穿過流化床床面的孔眼的分配進入干燥室，并于穿過的同時，與床面的干燥物料接觸，實現傳質熱交換，物料濕份被氣化，隨引風機引風的作用，夾帶于濕熱空氣中微粉物料經旋風分離器分離，回收的粉塵物料由旋風分離器底部設置關風機或蝶閥收料，夾帶于濕熱空氣中的微塵物料經除塵器布袋捕集進一步被回收，濕熱空氣由引風機排出，完成干燥生產的全過程。

The working principle of this dryer is to use the excitation frequency generated by the vibration motor to cause the fluidized bed host placed on the rubber spring to vibrate regularly due to the excitation frequency. Under normal no-load operation, the material is fed from the feeder at one end of the fluidized bed and fed into the drying chamber, i.e. the fluidized bed surface, through medium efficiency The highly efficient filtered heated air enters the drying chamber through the distribution of holes on the bed surface at the bottom of the fluidized bed, and at the same time, it comes into contact with the dry materials on the bed surface to achieve mass and heat exchange. The moisture content of the materials is vaporized, and the micro powder materials carried in the humid hot air are separated by the cyclone separator with the action of the induced draft fan. The recovered dust materials are collected by the closed fan or butterfly valve at the bottom of the cyclone separator, The fine dust materials carried in the humid and hot air are further collected by the dust collector bag, and the humid and hot air is discharged by the induced draft fan to complete the entire drying production process.

不適合的物料Unsuitable materials

本機可選用蒸汽、燃氣、燃油、燃煤為加熱熱源，使用范圍廣泛，可供用戶選擇。
被處理的物料受到一定的限制，有一定的使用條件：
(1).物料的粒徑一般大于0.5mm,小于8mm較為合適。粒徑太小易被氣流夾帶,粒徑太大不易流化。
(2).如幾種物料混合在一起進性流化床干燥,則要求幾種物料的密度比較接近。
(3).含水率過高且易粘結成團的物料,一般不適用。
(4).對產品要求外表美觀的物料不宜采用。
  This machine can choose steam, gas, fuel, and coal as heating sources, with a wide range of applications for users to choose from.

The processed materials are subject to certain restrictions and usage conditions:

(1) The particle size of the material is generally greater than 0.5mm, and less than 8mm is more suitable. A particle size that is too small is easily entrained by airflow, while a particle size that is too large is not easy to fluidize.

(2) If several materials are mixed together for fluidized bed drying, it is required that the densities of these materials are relatively close.

(3) Materials with high moisture content and easy agglomeration are generally not suitable.

(4) Materials that require a beautiful appearance for the product should not be used.

工藝流程Technological process

物料自進料口進入機內，在振動力作用下，物料沿水平方向拋擲向前連續運動，熱風向上穿過流化床同濕物料換熱后，濕空氣經旋風分離器（或脈沖式布袋除塵器）除塵后由排風排出，干燥物料由排料口排出，然后收集包裝。

The material enters the machine from the feeding port, and under the action of vibration, the material is thrown forward continuously in a horizontal direction. The hot air passes through the fluidized bed and exchanges heat with the wet material. The wet air is removed by the cyclone separator (or pulse bag filter) and discharged by the exhaust. The dry material is discharged from the discharge port and then collected and packaged.
