The utility model relates to a gas-liquid separation device for an LDS (
Laser Direct Structuring) supply
system, which comprises a gas-liquid separation tank, a motor is arranged at the bottom of the gas-liquid separation tank, the top of an output shaft of the motor is fixedly connected with a limiting
barrel, a rotating rod is arranged on the limiting
barrel, and a spiral
fan blade is fixedly connected outside the rotating rod. According to the gas-liquid separation device for the LDS supply
system, a gas-liquid mixture is converged into the gas-liquid separation tank through a gas-liquid mixture feeding
pipe, a motor drives a limiting
barrel, a rotating rod, a spiral
fan blade, a limiting rod and a scraping rod to rotate,
centrifugal force is generated when the spiral
fan blade rotates, gas and liquid in the gas-liquid mixture are separated, and the gas-liquid mixture is separated; the liquid is thrown to the inner wall of the gas-liquid separation tank, the gas rises and is discharged by the
exhaust pipe, the scraping rod rotates to scrape off the liquid attached to the inner wall of the gas-liquid separation tank, the liquid is discharged out of the gas-liquid separation tank through the liquid
discharge pipe, and the effect of automatically cleaning the liquid on the inner wall can be achieved.
