设备简介Equipment Introduction

LMZL型直线振动流化床干燥机采用振动电机产生的激振力的机理，而使干燥于流化床床面的被干燥物料，能在干燥过程中有序地向前推进直至出料。在生产工艺过程中，物料干燥在全封闭的状态下完成，由此减少物料交叉污染和人物流污染。直线振动流化床干燥技术不仅实现了动态干燥，较传统的烘箱、真空等静态干燥辐射传热，提高热效率、减少工艺环节、缩短生产周期、降低能源消耗，而且可连续生产，达到产业化生产规模。振动流化床由于应用风动力学和动力学热物理原理，使物料在干燥中，由于激振力的作用，使物料能达到自转和频率激振率的相互碰撞摩擦，不仅加速了物料内部含湿份向表面转移，而且物料的自转运动，可使全方位受热传质热交换，克服辐射单向传热因物料受热不均，而产生成品质量问题。

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

本干燥机的工作原理是应用振动电机产生的激振频率，使置于橡胶弹簧上的流化床主机由于激振频率而产生有规律的振动，在正常空载运转的状态下，由流化床一端的加料器投料，被干燥物料进入干燥室，即流化床床面，经中效、高效过滤后的加热空气由流化床底部穿过流化床床面的孔眼的分配进入干燥室，并于穿过的同时，与床面的干燥物料接触，实现传质热交换，物料湿份被气化，随引风机引风的作用，夹带于湿热空气中微粉物料经旋风分离器分离，回收的粉尘物料由旋风分离器底部设置关风机或蝶阀收料，夹带于湿热空气中的微尘物料经除尘器布袋捕集进一步被回收，湿热空气由引风机排出，完成干燥生产的全过程。

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.

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.

工艺流程Technological process

物料自进料口进入机内，在振动力作用下，物料沿水平方向抛掷向前连续运动，热风向上穿过流化床同湿物料换热后，湿空气经旋风分离器（或脉冲式布袋除尘器）除尘后由排风排出，干燥物料由排料口排出，然后收集包装。

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.
