Embodiment 1

[0040] Weigh 400g of flake aluminum powder with an average particle size of 30 μm and an aspect ratio of 31, such as figure 1 Add flake aluminum powder to the bottom of the fluidized bed through the feeding port 4 at the upper part of the fluidized bed. Then turn on the vacuum pump to evacuate the fluidized bed into a vacuum state, from the air vent in the fluidized bed, such as figure 1 The 1 in is the air vent, and the nitrogen gas is passed into the fluidized bed, and the flow rate is determined by the pressure gauge, and the flow rate of the fluidized gas is adjusted to 4.0m 3 / h.

Embodiment 2

[0047] Weigh 450 g of flake glass with an average particle diameter of 30 μm and an aspect ratio of 30, and add the flake glass to the bottom of the fluidized bed from the upper feed port in the fluidized bed. Then turn on the vacuum pump, and the fluidized bed is evacuated into a vacuum state. After the vacuum state, nitrogen gas is passed into the fluidized bed from the air vent in the fluidized bed, and the feed rate is determined by the pressure gauge, and the feed rate of the fluidized gas is adjusted to be 4.5m 3 / h. Through observation, the sheet glass in the fluidized bed can get a better fluidized state, and the gas distributor can rotate to drive the airflow to rotate.

Abstract

The invention belongs to the technical field of fluidization, in particular relates to a rotating airflow fluidization device and a flaky material fluidization method and aims at solving the problems that flaky materials can produce electrostatics easily in a fluidization process, adsorption and agglomeration can be caused easily and a fluidization dead zone can be easily formed in the fluidization process. The fluidization device comprises a gas distributor, the gas distributor can enable airflow to rotate and produce rotating airflow, and the flaky materials are driven to rotate by virtue of rotation of the airflow, so that the flaky materials can produce a centrifugal force and are separated from each other, and influence of electrostatic adsorption is eliminated; the rotation of the airflow also can drive the flaky materials in the fluidization dead zone at the bottom of the fluidization bed, so that the fluidization dead zone is eliminated. The rotating airflow fluidization device provided by the invention is simple and scientific in structure, strong in industrial applicability and applicable to popularization and application.

Description

technical field [0001] The invention relates to the technical field of fluidization, in particular to a swirling air flow fluidization device and a fluidization method for sheet materials. Background technique [0002] A fluidized bed suspends a large number of solid particles in a moving fluid, so that the particles have some apparent characteristics of the fluid. This fluid-solid contact state is called solid fluidization, that is, a fluidized bed. As an important flow-solid operation equipment, the fluidized bed has been widely used in particle transportation and transmission, ore dressing, coal combustion and conversion, petroleum processing industry, organic synthesis industry, and material industry. [0003] Fluidization technology is to suspend solid bulk materials in the moving fluid, so that the particles are out of contact with each other, so as to eliminate the internal friction phenomenon between particles and achieve the purpose of solid fluidization. This tech...
