Novel drying device for fluidized bed

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.

Description

technical field [0001] The present invention relates to the relevant technical field of fluidized bed drying equipment, in particular, relates to a novel fluidized bed drying device. Background technique [0002] During the continuous operation of the current fluidized bed, it is easy to deposit dry objects or take shortcuts, which greatly increases the difficulty of starting the fluidized bed. [0003] At present, when the hot air in the fluidized bed enters the drying chamber, the air is distributed through the mesh plate. The air distribution method of the mesh plate makes the angle between the direction of the hot air and the forward direction of the material be 90°. In actual operation, if it enters the flow If the wind speed or air volume of the hot air in the fluidized bed is too large, the dried materials will be concentrated through the top of the fluidized bed drying chamber (chamber) to the outlet, resulting in insufficient drying of the materials.

[0002] During the continuous operation of the current fluidized bed, it is easy to deposit dry objects or take shortcuts, which greatly increases the difficulty of starting the fluidized bed

[0003] At present, when the hot air in the fluidized bed enters the drying chamber, the air is distributed through the mesh plate. The air distribution method of the mesh plate makes the angle between the direction of the hot air and the forward direction of the material be 90°. In actual operation, if it enters the flow Excessive wind speed or air volume of the hot air in the fluidized bed will make the dried materials concentrate through the top of the fluidized bed drying chamber (chamber) to the outlet, resulting in insufficient drying of the materials

[0004] On the contrary, if the wind speed or air volume of the hot air entering the fluidized bed is too small, it will not be enough to blow up the materials to be dried, causing the materials to deposit between the baffles in the drying chamber (chamber), reducing the drying effect

[0005] Therefore, it is necessary to design a fluidized bed with a new structure to solve the problem of insufficient material drying and material deposition
