Widened vibrated fluidized bed structure

Abstract

The invention relates to a widened vibrated fluidized bed structure which comprises a vulcanized bed body and an air suction hood. A feeding hopper is arranged at one end of the air suction hood; an air suction opening is formed in the upper side of the air suction hood; a discharging hopper is arranged at one end, opposite to the feeding hopper, of the vulcanized bed body; a vibrating seat is mounted at the bottom of the fluidized bed body; a hot air inlet is formed in the side part of the fluidized bed body; an air distribution plate higher than the hot air inlet is horizontally arranged inthe fluidized bed body; a vibrating motor is mounted on the outer side of the fluidized bed body; a circular flange is welded to the position, where the vibration motor is installed, of the outer sideof the fluidized bed body; a circular installation plate is connected onto the circular flange through bolts; a motor fixing plate is welded to the circular installation plate; and the vibration motor is connected onto the motor fixing plate through bolts. The widened vibrated fluidized bed structure provided by the invention is simpler in overall structural design, easy to machine, produce and manufacture and convenient to maintain daily; and the vibration direction and speed required by material drying can be met by adjusting the inclination angle of the vibration motor.

Description

technical field [0001] The invention relates to a widened vibrating fluidized bed structure. Background technique [0002] Vibrating fluidized bed, the full name is vibrating fluidized bed dryer, is a new type of vibrating fluidized bed dryer technology that began to appear in the 1960s when a vibration source was introduced on the basis of ordinary fluidized bed dryers. Drying equipment is now increasingly becoming one of the main models in drying equipment. Its main working principle is to feed the material to be dried into the bed through the feed port, and float the material on the upper layer. The material is thrown and loosened under the action of the vibrating motor, and hot steam is continuously injected from the outside. The material is in this In the fluidized state, in the process of continuous forward movement, it is fully mixed and dispersed with hot steam, heat exchanged and then dried by hot air, and then flows out through the discharge device. Vibrating flu...

Problems solved by technology

At present, the vibration motor installation method generally used in large fluidized bed dryers is that the motor separation box type vibration exciter is fixed at the end of the fluidized bed leaf spring. The vibration transmission mechanism of this installation is relatively complicated and costly. Once the installation mechanism is due to Parts are worn or damaged due to vibration, and its maintenance is difficult, resulting in increased vibration noise and adverse changes in the direction and speed of material vibration

Generally, the vibrating base of a vibrating fluidized bed is composed of a single-layer base and a vibrating spring, which is unfavorable for the design of a single-layer vibrating base of a large-scale vibrating fluidized bed. The effect of cushioning the exciting force is limited, and the exciting force of the vibration spring will increase with the vibration time, which will eventually lead to its damage, so the life of the vibration spring is short and needs to be replaced frequently

Part of the bed material is made of high-quality metal, which increases the overall quality of the bed and requires a lot of energy consumption
