Abstract
The invention relates to a novel drying device for a fluidized bed. The novel drying device mainly comprises a box body. A feeding port and an air outlet are formed in the top of the box body respectively. An air inlet and a discharging port are formed in the two sides of the box body respectively. An air distribution board is transversely arranged in the box body. Multiple baffles are longitudinally arranged between the air distribution board and the top of the box body. Discharging valves are arranged between the baffles and the air distribution board. The air distribution board is provided with multiple rows of air outflow holes, the directions of each row of air outflow holes are the same, and the directions of the air outflow holes in the adjacent rows are opposite. Air flows in through the air inlet, is guided by the air distribution board and forms turbulent flow in the box body so as to drive materials to move turbulently. By the adoption of the novel drying device for the fluidized bed, a brand-new structure is designed, the materials are continuously in the turbulent state in the fluidized bed so as to be prevented from being bonded, and the effect that the materials are fully dried and heated is achieved.

Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment：A kind of novel fluidized bed drying device, its structure is referred to shown in Fig. 1：Including casing 2, inside casing 2
It is air intake passage 9, air distribution plate 8 and case that level is provided between the bottom of the air distribution plate 8 of multiple airtight connections, air distribution plate 8 and casing 2
It is hothouse 12 between the top of body 2.
One end of air intake passage 9 protrudes from casing 2, is that flutter valve 10 is provided with charging aperture 11, and charging aperture 11, realizes
Blow to the pulsed of hothouse 12.
In above-mentioned casing 2, the left end at top is provided with a charging aperture 1, the middle position at top and position difference of keeping right
An air outlet 4 is provided with, charging aperture 1 and air outlet 4 are connected with hothouse 12, the right side of casing 2 is the passage 5 that gathers materials.
In hothouse 12, in order to improve turbulence effects, multiple baffle plates 3 are additionally provided with.The length of adjacent baffle plate 3 is not
