振动流化床干燥机，简称振动流化床，是一种适用于颗料状、粉末状物料干燥的新型流态化高效干燥设备。它具有便于操作、节能、环保等优点，并已逐渐成为干燥设备中的主要机型。以下是对振动流化床干燥机的详细介绍：

1, the basic overview of vibrating fluidized bed dryer

** * Definition ** : Vibrating fluidized bed dryer is a new drying device that applies a vibration source with specific requirements to an ordinary fluidized bed dryer.

** * Vibration source ** : the excitation method can be divided into motor method, electromagnetic induction method, crankshaft or eccentric method, pneumatic or hydraulic method, etc.

** * Working principle ** : The double action of mechanical vibration and air perforation is used to make the material in a fluid state and continue to move forward. Under the action of vibration force, the material is thrown forward continuously in the horizontal direction. At the same time, the hot air input at the bottom of the bed makes the material in a fluid state, and the material particles are fully in contact with the hot air, thus achieving the drying effect efficiently.

1、振动流化床干燥机基本概述

* **定义**：振动流化床干燥机是将特定要求的振动源施加于普通流化床干燥机上的新型干燥装置。

* **振动源**：其激振方法可分为电动机法、电磁感应法、曲轴或偏心轮法、气动或液压法等。

* **工作原理**：利用机械振动和气流穿孔双重作用，使物料处于流态化状态并持续向前运动。物料在振动力的作用下，沿水平方向抛掷向前连续运动，同时床底输入的热风使物料处于流化状态，物料颗粒与热风充分接触，从而高效地实现干燥效果。

2, the internal structure of the vibrating fluidized bed dryer

The internal structure of the vibrating fluidized bed dryer manufactured by Jiangsu Bohong Drying Company mainly includes the following parts:

1. ** Air inlet mechanism ** : composed of air inlet pipe, air inlet chamber, gas pre-distributor and gas distribution plate, the main function is to transport air to the dryer and ensure uniform gas distribution.

2. ** Bed body ** : including shell, inlet and outlet, air duct and other parts. The shell provides a closed working space for the dryer, the inlet and outlet are used for the inlet and outlet of materials, and the air duct is a channel for air flow.

3. ** Vibration mechanism ** : composed of vibration motor and spring support. Vibration motor generates vibration, so that the material in the dryer can be fully rolled and dried; Spring supports are used to mitigate vibration, protect the structure of the dryer and reduce noise.

4. ** bracket ** : used to support the whole dryer to make it work stably.

5. ** Fluidization chamber ** : The material moves from the feed port to the discharge port with the help of vibration and air flow, and presents a fluidization state to achieve efficient drying.

2、振动流化床干燥机内部结构

江苏博鸿干燥公司制造的振动流化床干燥机的内部结构主要包括以下几个部分：

1. **进风机构**：由进风管、进风室、气体预分布器、气体分布板组成，主要作用是向干燥机内输送空气，并确保气体分布均匀。

2. **床体**：包括壳体、进出料口、风管等部分。壳体为干燥机提供了一个封闭的工作空间，进出料口用于物料的进出，风管则是空气流动的通道。

3. **振动机构**：由振动电动机和弹簧支承组成。振动电动机产生振动，使干燥机内的物料得以充分翻滚和干燥；弹簧支承则用于减缓振动，保护干燥机的结构和降低噪音。

4. **支架**：用于承托整个干燥机，使其稳定工作。

5. **流化室**：物料在此处借助振动和气流从进料口移动到出料口，并呈现流化状态，实现高效干燥。

3, vibrating fluidized bed dryer working characteristics

1. ** High thermal efficiency ** : Because the material is subject to mechanical vibration in the vibrating fluidized bed, it is in a state of motion, and dynamic drying can be achieved only by injecting the right amount of hot air, so the thermal efficiency is high.

2. ** Uniform drying ** : The material is subjected to uniform vibration and airflow in the vibrating fluidized bed, making the material particles fully contact with the hot air and drying evenly.

3. ** Wide range of application ** : Vibrating fluidized bed dryer is widely used in petrochemical, fine chemical, medicine, food, grain and oil, waste residue treatment and other fields, suitable for a variety of high humidity, sticky or difficult to dry materials.

3、振动流化床干燥机工作特点

1. **热效率高**：由于物料在振动流化床中受机械振动的作用，处于运动状态，只需鼓入适量的热空气便可达到动态干燥，因而热效率高。

2. **干燥均匀**：物料在振动流化床中受到均匀的振动和气流作用，使得物料颗粒与热风充分接触，干燥均匀。

3. **适用范围广**：振动流化床干燥机广泛应用于石油化工、精细化工、医药、食品、粮油、废渣处理等领域，适用于各种高湿度、粘性或难以干燥的物料。

4. Application field of vibrating fluidized bed dryer

Vibrating fluidized bed dryer technology combines heat and mass transfer theory and is widely used in the following areas:

** * Polymer field ** * : such as ABS-copolymer, plexiglas, polycarbonate, polyethylene, polypropylene and other substances containing water or organic volatile solvents drying and cooling.
