Further, the linear speed of the rotating disc 1 is greater than the speed of the splashed objects passing through the straight slit of the rotating disc 1, so that the upper layer disc can block the splashed objects, and operators can observe the conditions in the vacuum chamber conveniently.

Further, the distance between the upper layer of disc and the lower layer of disc is 2-10 mm.

Further, the rotating disc 1 is made of stainless steel material, and the upper and lower layers of the rotating disc 1 are fixedly connected through an aluminum pipe 12.
