Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in figures 1-2, a mica powder subdivision device comprises a classifying tank 1, wherein a cyclone separator 2 is arranged in the classifying tank 1, the top of the cyclone separator 2 is connected with an air extractor 3, the top of the cyclone separator 2 is also connected with a pulse dust collector 11, the middle part of the classifying tank 1 is connected with a feeding tank 4, a discharge port 2a of the cyclone separator 2 is connected with a storage tank 5, and the bottom of the classifying tank 1 is provided with a wind-off assembly 6.
In this embodiment, the cyclone 2 and the pulse dust collector 11 are conventional, and commercially available products can be used. The air extractor 3 is a vortex fan, an axial flow fan or a vacuum pump, and is used for providing vacuum for the cyclone separator 2, so that mica powder is pumped into the classifying tank 1 from the feeding tank 4 and then enters the cyclone separator 4 from the classifying tank 1.
When mica powder enters the classifying tank 1, the powder impacts the classifying tank 1 to be closed, and under the action of the airflow of the cyclone separator 2, vortex is formed to separate coarse particles from fine particles, and the fine particles enter the cyclone separator and enter the storage tank 5 through the discharge hole 2a to be collected. Coarse particles descend along the inner wall of the classifying tank 1 to the position of the air-seal assembly 6. Forming a separation of coarse and fine particles.
The classifying tank 1 is provided with a feeding taper pipe 7, the feeding taper pipe 7 is connected with the feeding tank 4, and the feeding taper pipe 7 is positioned below the cyclone separator 2. The feeding taper pipe 7 is arranged obliquely downwards, and the outlet of the feeding taper pipe 7 is close to the central line of the classifying tank 1.
The feeding tank 4 is internally provided with a feeding pipe 8, the feeding pipe 8 is connected with a feeding taper pipe 7 through a pipeline, the bottom of the feeding pipe 8 is provided with a feeding port 9 which is obliquely arranged, and the feeding port extends to the bottom of the feeding tank 4. The feed pipe 8 is arranged so that the mica powder gradually sinks along the outer wall of the feed pipe 8 in the process of being sucked by the feed pipe 8, thereby enabling the material in the feed tank 4 to be continuously sucked into the cyclone separator.
A plurality of impact baffles 10 which are arranged in a staggered way are arranged between the feeding taper pipe 7 and the cyclone separator 2, and gaps are reserved between every two adjacent impact baffles 10.
When the mica powder encounters the impact baffles 10, collision is generated, some of the powder in a bundle colloid form is scattered, and the scattered powder passes through gaps between the impact baffles 10 and enters the cyclone separator.
