Abstract

The invention provides an airflow sorting machine and a multi-product material sorting method. The airflow sorting machine comprises a sorting bed (2), an air supply mechanism (3) and a vibration mechanism (4), a feeding port (24) is formed in one end of the sorting bed (2), a discharging port (25) is formed in the other end of the sorting bed (2), a gangue discharging port (26) is formed in the bottom of the sorting bed (2), the vibration direction of the sorting bed (2) deviates to the feeding port (24), the vibration mechanism (4) can make the sorting bed (2) vibrate in the vibration direction, and the air supply mechanism (3) can provide air with a preset waveform for the sorting bed (2). According to the airflow sorting machine and the multi-product material sorting method, the vibration direction of the sorting bed deviates to the feeding port, clean coal and gangue in raw coal materials with low gangue content can be rapidly separated up and down, the gangue can be gathered on the sorting bed, and the content of the gangue in substances discharged from the gangue discharging port is greatly increased.

Description

technical field

[0001] The invention relates to the technical field of coal preparation equipment, in particular to an air flow separator and a multi-product material separation method. Background technique

[0002] The vibration direction A of the sorting bed 2 of the existing air jigging separator is all biased towards the feed inlet 24, that is, as figure 1 As shown, the angle α between the vibration direction A of the sorting bed 2 and the direction B of the bed surface of the sorting bed 2 towards the light material discharge port 25 is smaller than the vibration direction A of the sorting bed and the direction B of the sorting bed 2 The angle α2 between the directions C of the bed surface towards the feed port 24 . During the vibration process of sorting bed 2 along the vibration direction, the clean coal and gangue in the raw coal material to be sorted will be layered up and down according to the density, and at the same time, both the clean coal and gangue will move...
