Embodiment Construction

[0013] In order to make the technical solution of the present invention clearer, the present invention will be further described below in conjunction with specific embodiments of the accompanying drawings.

[0014] Such as figure 1 As shown, a multi-layer rotary grain drying fluidized bed includes a hopper 1, a bubbling fluidized bed dryer 2, a cyclone separator 3, a dehumidifier 4, a collector 5, a fluidized blower 6, a motor 7, and a heating blower 8. It is characterized in that: the feeding hopper 1 is connected to the bubbling fluidized bed dryer 2, in which a rotating air distribution plate 62 is arranged, the motor 7 provides the rotational power, and the heating blower 8 provides heating. The tail is connected to the cyclone separator 3, the material side is concavely connected to the collector 5, the air side is connected to the dehumidifier 4, and the tail is provided with an exhaust port 64 and an air return pipe 65.

[0015] Further, the rotating air distribution p...

Abstract

The invention relates to a multilayer-rotation grain-drying fluidized bed which comprises a receiving hopper, a bubbling fluidized bed dryer, a cyclone separator, a dehumidifier, a collector, a fluidization air blower, a motor and a heating air blower. The multilayer-rotation grain-drying fluidized bed is characterized int hat the receiving hopper is connected with the bubbling fluidized bed dryer; a rotary air distribution plate is arranged in the bubbling fluidized bed dryer; rotating power is provided by the motor; and heating is provided for the heating air blower. The cyclone separator isconnected to the tail part, the collector is connected to a material side in a concave way, the dehumidifier is connected to an air side, and an exhaust port and an air return pipe are arranged on the tail part, so that after materials are added, grains can be high-efficiently dehumidified in an energy-saving environmental-friendly way through the device. The multilayer-rotation grain-drying fluidized bed provided by the invention is high-efficiency in use, energy-saving, environmental-friendly, and easy to popularize.

Description

technical field [0001] The invention relates to a drying fluidized bed, in particular to a multilayer rotating grain drying fluidized bed. Background technique [0002] The current grain drying fluidized bed is used, but there are many problems: 1. The existing grain drying efficiency is low; 2. The grain drying is not sufficient; 3.
