Paper machine runner foam-free optimization system

The invention provides a foam-free optimization system for a flow channel of a paper machine, and relates to the technical field of flow channels of paper machines. The conveying part is arranged at the top of the rinsing part; the drainage part is arranged on the rear side of the rinsing part; the swinging part is arranged in the rinsing part; the defoaming part is arranged in the rinsing part; the defoaming part floats on the water surface of the rinsing water under the action of buoyancy, so that a floating block drives a foam filtering frame and a foam discharging frame to slide on a stable frame, foam is conveniently pushed into the foam discharging frame, and the foam in an internal foam discharging device is discharged through telescopic hoses on the left side and the right side of the foam discharging frame; the invention relates to a flow channel of a paper machine, which solves the problem that the quality of paper is affected due to the fact that foams generated by air gaps in paper scraps cannot b
