The vibrating fluidized bed dryer is a new type of drying equipment designed by the principle of vibration fluidization. It has the characteristics of high efficiency, energy saving and excellent performance. It is suitable for the drying of powdery and granular materials in various industries such as chemical, pharmaceutical, food, seed, beverage and slag.
I. Main Structure The main structure of this series of dryers is basically the same, which is mainly divided into upper cover, box, air inlet, observation window and temperature measuring hole. The fluidizing chamber of the material between the upper cover and the fluidized bed plate is led out by the air inlet, and the temperature measuring hole is used to detect the temperature in the fluidizing chamber. The operation of the material can be monitored by the observation window. The tank is a plenum chamber, and the hot air enters through the air inlet to form a certain pressure, so that the gas distribution through the fluidized bed is uniform, and the wind temperature at the place can be detected by a temperature measuring sensor (generally not used). Material that falls into the tank due to abnormal operation can be removed.
Second, the working principle of vibrating fluidized bed dryer The machine is driven by a vibration motor to perform periodic vibration at a certain fixed frequency along a certain direction. The material to be treated forms a fluidized form under the action of the exciting force and the medium, thereby making the material The particles are in full contact with the medium to complete the heat and mass transfer process and achieve the purpose of drying.
Third, the machine is a new product designed by our factory in combination with China's national conditions. Each technical indicator ranks first in the same category and has the following advantages:
1. The fluidization is stable, and there is no dead bed and blow through phenomenon, so that a uniform product can be obtained.
2. The vibration source is a vibration motor, which is stable in operation, convenient in maintenance, low in noise and long in equipment life.
3, the adjustability is good, the thickness of the material layer and the residence time of the material in the machine and the amplitude change of the machine can be steplessly adjusted within the design range.
4, adapt to the width of the surface, for different specific gravity, particle size, water content, water-containing materials can be adapted.
5, the surface damage to the material is small, can be used for the drying of fragile materials, material particles are irregular, and does not affect the working effect.
6. The heating method is direct heating, high thermal efficiency and good energy saving effect.
Fourth, vibration fluidized bed dryer maintenance and maintenance 1, cleaning regularly open the observation window and the material discharge port, remove the material retained on the fluidized bed board and materials dropped into the box. If the fluidized bed stencil is clogged, it should be treated. When washing, after washing, the equipment should be dried in time to remove moisture, so as to avoid corrosion of the equipment and affect the next material handling effect.
2. The vibration motor should be regularly maintained and lubricated.
3. Check the working condition of the vibration isolation rubber spring. When the vibration isolation spring has aging cracks or the installation height is lower than 105mm, it should be replaced. In addition, due to the low installation height or aging cracks, all the vibration isolation springs should be replaced together, and the free height error of each rubber spring is not more than 3mm. How to replace the rubber spring: The rubber spring must be replaced together, and only one way can be used for replacement. In the replacement, when lifting the ejector, the weight balance of the machine must be maintained. For example, the lifting amount of the jack remains the same, and it is replaced with a small torque of zui. Replacement of the rubber spring must be strictly checked. The free height is the same height group based on H=130mm. Note: When replacing the vibration isolating rubber according to the pushing and lifting methods, the height of the top (pull) of the machine should ensure that the dryer body does not cause a rollover accident.
4. Replace the soft connecting tube: When the soft connecting tube is damaged, it should be replaced to avoid fluctuation of the air supply volume and affect the material handling effect. Refer to the installation instructions for the reinstallation method when replacing.
The company supplies a large number of drying equipment, if necessary.
