Abstract

The invention relates to a vibrated fluidized bed. The vibrated fluidized bed comprises a drying cavity and an excitation source, two axial ends of the drying cavity are provided with an air inlet and an air outlet respectively, a vibration screen plate is arranged in the middle of the drying cavity, the wall surface of the hollow middle of the drying cavity is provided with an annular groove corresponding to the vibration screen plate, an annular spring piece is arranged at each of upper and lower ends of the annular groove, the vibration screen plate is fixed into the middle of the annular groove through the spring pieces, and a plurality of air guide holes are densely distributed in the vibration screen plate. A filter screen is arranged between the drying cavity and a vibration mechanism, the wall surface of the drying cavity between the lower surface of the filter screen and the vibration mechanism is provided with a feeding port, the wall surface of one side, opposite to the feeding port, of the wall surface of the drying cavity is provided with a discharging port, and height of the feeding port relative to the upper surface of the vibration screen plate is larger than that of the discharging port. The vibration screen plate inclines towards the discharging port, and the excitation source comprises a pulse valve which is connected onto an exhaust port.

Description

technical field [0001] The invention relates to a vibrating fluidized bed, which belongs to the field of drying equipment. Background technique [0002] The vibrating fluidized bed dryer is suitable for the drying production of granular, flake and strip crystalline water materials in the pharmaceutical, chemical and food industries. It adopts the drying mechanism of vibrating fluidization and is a typical drying production equipment in the field of drying technology. [0003] The general principle of the vibrating fluidized bed is to drive the vibrating sieve plate to vibrate through an exciting motor fixed on the drying box, so that the material to be dried is in a fluid state to achieve drying of the material, and the vibrating sieve plate is mainly buffered by a spring , the use of steel springs is heavy, which will increase the load of the excitation motor, and the noise will be relatively increased, and the use of titanium springs will increase the manufacturing cost of...
