HGZZ series vibration fluidized bed dryer

When granular materials are dried in a common fluidized bed, the material particles should be uniform and have a certain size, otherwise a sulcus flow and a stagnation zone will be formed. When the particle size distribution is wide, the entrainment will be serious, and the humidity will easily agglomerate. Due to the back mixing of the particles, the distribution range of the residence time of the particles is large, and the moisture content of the particles is uneven, so the use range of the ordinary fluidized bed drying device is limited. In order to overcome its shortcomings, a lot of research has been done abroad to improve the performance of fluidized beds. Especially in today's tight energy environment, it is of great significance to strengthen the mass and heat transfer process, save energy and improve quality, so that the fluidized bed device has broad adaptability and economic rationality. With the help of relevant scientific research units, our company has developed a vibrating fluidized bed drying (cooling, humidifying) machine with reference to imported products. The machine has advanced design, reliable quality, wide application range, and has significant energy saving and energy drying capabilities. The advantages of materials that are difficult to dry on other equipment are generally welcomed by various industries.

Principle and structure:

The vibration fluidized bed dryer is made by the vibration motor to make the machine vibrate, the material jumps forward under the action of the excitation force in the given direction, and the hot air input at the bottom of the bed makes the material in a fluidized state. The hot air is fully contacted to achieve the desired drying effect.

The material enters from the material inlet. The material on the vibrating tank is in orthogonal contact with the hot air passing through the lower part of the vibrating tank to transfer heat. The wet air is drawn out by the induced wind and the dry material is discharged from the discharge port.

Uses and main features:

This machine is widely used in chemical industry, light industry, medicine, food, plastics, grain and oil, slag, salt, tobacco and other industries to dry, cool and humidify powdery and granular materials. Cooling and humidifying operations. Its characteristics are as follows:

<1> It is driven by a vibration motor, with stable operation, low noise, long life and easy maintenance.

<2> Vibration makes the material easily reach the fluidized state, and increases the effective heat transfer coefficient, so the thermal efficiency is high. The bed temperature is evenly distributed without local overheating. Uniform fluidization, no dead angle and blow-through. Vibration plays a role in transportation and is also conducive to energy conservation. Energy saving of 30-60% compared with general drying equipment.

<3> The thickness of the material layer and the speed and amplitude of the movement in the machine can be adjusted steplessly, the adjustability is good, and the speed surface is wide.

<4> The surface of the material is less damaged, which can be used for drying fragile materials. It can also be used when the particles of the material are irregular, without affecting the effect.

The fully enclosed structure effectively prevents cross-contamination of materials and the outside world, clean the environment, and improves working conditions.

<5> Vibration promotes fluidization, reduces air demand, and reduces particle entrainment.
