Double mass vibrating fluidized bed dryer

The new generation of large-scale vibrating fluidized bed dryer developed has the advantages of energy saving and excellent performance, especially for solving the problems of materials difficult to dry on other drying equipment and obvious outstanding energy saving features Therefore, the dryer is widely used in various drying application fields, widely applicable to petrochemical industry, fine chemical industry, medicine, food, grain and oil, feed, salt industry Seafood processing and ultra-fine drying and other fields The double mass vibrating fluidized bed dryer is mainly composed of upper chamber, air box, base, fluidized bed, etc The upper chamber and the air box form the upper mass, and the lower mass is under the base The upper and lower mass are connected by plate spring and spiral spring, and the lower mass and the foundation are isolated by rubber cushion The rear of the air box is equipped with a box vibrator The box type exciter is connected by the transmission shaft and driven by the motor to generate the horizontal excitation force Under the action of the plate spring (resonance spring), the component force in the vertical direction and the component force in the horizontal direction are generated The component force in the vertical direction, together with the hot air passing through the nozzle plate, throws up the material on the nozzle plate to make the material in the fluidization state, while the component force in the horizontal direction makes the material It is transported forward at a certain speed and discharged through overflow weir and discharge hopper to complete drying operation The excitation source is installed at the head of the equipment, which improves the stress condition of the whole equipment, realizes the use of a double mass vibrating fluidized bed dryer instead of several ordinary vibrating beds in series, reduces the equipment investment and project cost, and the advanced vibration structure ensures the synchronous vibration in the width and length direction of the large vibrating bed, and solves the bias current of the ordinary double motor vibrating bed Ditch flow problem Because of the increase of length and area, the residence time of the material is greatly prolonged, which is beneficial to the deep drying of the large particle material At the same time, the application of vibration and the reduction of fluidization speed are conducive to reducing wear and maintaining the stability of particles High frequency vibration makes the distribution of hot air more uniform and improves the heat transfer efficiency of hot air and wet materials At the same time, the high-frequency vibration makes the bottom materials in the process of slowly moving to the discharge, avoiding the problems of local dead bed, wall accumulation, channel flow, surge and so on in the static fluidized bed, which can make the double mass vibration fluidized bed dryer be applied to the drying of viscous polymer and viscous organic matter The distribution plate is covered with a cap similar to a duck's beak, which can generate horizontal airflow, reduce the contact and overheating between the product and the bottom plate of the dryer, and have high-speed shear effect on large particles, so as to ensure the uniform fluidization of materials When the dryer stops, the product staying in the fluidization room can be prevented from falling into the pressure equalizing air box The material level in the dryer can be adjusted by the overflow weir to keep the same during the drying process The observation window is located on both sides of the fluidization chamber, which is convenient to observe the fluidization state of the chamber Application fields: MBS, ABS, adipic acid, polyacrylamide, acrylamide crystal, polytetrafluoroethylene, phenolic resin, nylon, polypropylene resin, polyester chip, PVC, soda ash, salt, ammonium nitrate, potassium carbonate, potassium chlorate, potassium chloride, potassium nitrate, potassium phosphate, potassium sulfate, fermented feed, expanded pellet feed, organic fertilizer, alcohol waste, antibiotic residue, garbage, etc.
