Pulp feeding system for paper pulp papermaking

Abstract

The utility model discloses a paper pulp papermaking sizing system which comprises a pulp forming pool and a white water barrel, the pulp forming pool penetrates into the white water barrel through a pipeline and extends to an inlet of an eccentric conical pipe, and the other end of the eccentric conical pipe is communicated to a first-section screen through a first pulp pump; the top of the first-section screen is connected with a first laitance conveying pipe, the bottom of the first-section screen is connected with a first slag slurry conveying pipe, the other ends of the first laitance conveying pipe and the first slag slurry conveying pipe are communicated with a slag slurry collecting tank, and the slag slurry collecting tank is communicated with a second-section screen through a second slurry pump; according to the utility model, through the cooperation of the first-section screen and the second-section screen, slurry enters the first-section screen for screening, laitance and slag slurry respectively enter the slag slurry collecting tank through the first laitance conveying pipe and the first slag slurry conveying pipe, and the slurry in the slag slurry collecting tank is conveyed to the second-section screen by the second slurry pump for secondary screening; secondary circulation screening of paper pulp is achieved, waste of the paper pulp is reduced, and the resource utilization rate is increased.
