Because it operates under fully sealed negative pressure, there is no dust on site, low noise, and is very environmentally friendly. In addition, it also has the following advantages:

First of all, the diameter of the sorter is increased from 800mm to 850-950mm, which improves the production capacity of the equipment; while improving the sorting effect of the equipment, it also reduces the speed of the main shaft and greatly increases the running time of the equipment; While increasing the production capacity of the equipment and improving the sorting effect, the current is not increased, thereby saving energy.

Secondly, the sorting accuracy, fineness and efficiency are high, and the sorting range can be adjusted arbitrarily within 30-200 mesh, and the scope of application is wide.

Finally, it is more humanized to adjust the sorting effect, easy to operate, has a long service life, and is easy to install and maintain.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1-19, the airflow separator includes a frame 1, a motor 2, a pulley 3, a main shaft 4, a hopper 5, an adjustment ring 6, a distribution tray 7, a buffer ring 8, a vortex ring 9, and a rotor 10. Sorter 11, bearing housing 12 and shut-off fan 13, motor fixing seat 14 is installed on the top of frame 1, and fixing seat 14 is fixedly connected with the shell of motor 2. The output shaft of the motor 2 faces upwards, and its output shaft is interlocked with the driven pulley 17 on the upper end of the main shaft 4 through the belt 15 , and the belt 15 is equipped with a shield 16 . The main shaft 4 is positioned on the bearing seat 12 through two bearings 18 , 19 . The lower end of the main shaft 4 extends into the sorter 11; the sorter 11 is fixed on the frame 1 through a connecting plate, the upper mouth of the sorter 11 communicates with the feed hopper 5, and the lower part is two discharge ports 20, 21 , are heavy material export and light material export respectively. Two discharge outlets are equipped with related fan 13. The upper inside of the sorter 11 outer cylinder is provided with an adjustable ring 6 that can move up and down, and the inner wall of the adjustable ring 6 is welded with a circle of evenly distributed inclined blades 61, and the inclination angle of the adjustable ring 6 blades is 12 degrees. The adjusting ring 6 is connected with the fixing seat fixed on the connecting plate through the screw rod 22, and the screw rod 22 is driven by the rotation of the hand wheel to make the adjusting ring 6 move up and down. A buffer ring 8 is arranged on the inner top of the separator 11 , the lower end of the main shaft 4 is fixedly connected with the rotor 10 , and the swirl ring 9 is fixed on the inner cylinder of the separator 11 . The gap between the inner circle formed by the blades of the adjustment ring 6 and the outer circle formed by the blades of the swirl ring 9 is 3.5 mm.
