When the powder-gas separation device works, a powder-gas mixture tangentially enters the separation cavity 3 through the gas inlet pipeline 4 and circularly moves to form an outward-rotating gas flow, powder is thrown to the side wall of the separation cavity 3 due to high density, the powder loses inertia force and falls along the side wall of the separation cavity 3, and the powder enters the conveying device cone 15 after being filtered by the screen 14; the rotating gas in the separator cone 8 gradually draws close to the center along with the contraction of the cone, the tangential speed is continuously increased, finally, the rotating gas continuously makes spiral motion from bottom to top in the same rotating direction to form internal rotation gas flow, and finally, the purified gas is discharged from the gas outlet 7 through the connecting sleeve 5 and the exhaust spiral body 6.

And the powder in the conveying device centrum 15 is discharged through the cooperation of the upper conversion valve 17 and the lower conversion valve 19, and the concrete steps are as follows:

1. the upper transfer valve 17 is opened and the powder passes down through the upper transfer valve 17 into the intermediate pipe 18; at this time, the lower switching valve 19 is closed, the spiral gas inlet pipe 22 continuously supplies gas, and the conveying gas inlet pipe 21 stops supplying gas;

2. the upper switching valve 17 is closed;

3. lower switching valve 19 is opened; at the moment, the upper conversion valve 17 is closed, the spiral gas inlet pipe 22 continuously supplies gas, and the conveying gas inlet pipe 21 is communicated with the gas supply; due to the large pressure in the intermediate pipe 18, the powder is conveyed to the nozzle for discharge through the lower switching valve 19;

4. the lower switching valve 19 is closed and after a short delay the upper switching valve 17 is reopened and the above steps are repeated.

When the color needs to be changed for cleaning, the jacking cylinder 12 contracts, the rotating frame 11 is moved downwards to be separated from the separator body 1, and then the supporting arm 10 is rotated to move the whole dense phase conveying device away from the lower part of the separator body 1.
