The invention relates to a sealed vibration screen for
pipe chain
chip removal. The closed vibration screen mainly comprises two parts including a vibration screen body and a sealing device; the vibration screen body is composed of a
buffer tank, a screen frame, an upper-layer screen net, vibration excitation motors, a lower-layer screen net, a base and vibration reduction springs; the sealing device is composed of a feeding-end upper sealing cover, a jet pump, an elastic sealing device body, a discharging-end upper sealing cover, an outlet sealing cover, a
pipe chain
chip removal device, a liquid sealing baffle and an underflow emptying valve; the vibration screen body is arranged in the sealing device, the feeding-end upper sealing cover and the discharging-end upper sealing cover are arranged above the screen frame, and the elastic sealing device body is installed between the screen frame and the feeding-end and discharging-end upper sealing covers; the liquid sealing baffle is arranged at the left side of the base, and an S-shaped
pipe formed in the portion, in the base, of the liquid sealing baffle prevents
hydrogen sulfide from leaking; the pipe chain
chip removal device is installed at the discharging portion of the screen frame and can continuously and efficiently remove rock chip particles, the jet pump is installed on the feeding-end upper sealing cover, and the
hydrogen sulfide is recycled through the jet pump. The sealed vibration screen is simple in structure and high in safety, the screening efficiency requirement of the vibration screen can be met, the rock chips are timely removed, the
hydrogen sulfide is effectively controlled and recycled, and the effect is obvious.
