Pulping machine and long fiber beating degree control method and system thereof

Abstract

The invention discloses a pulping machine and a long fiber beating degree control method and system thereof. The pulping machine is provided with a pulping chamber, a return pipe and an output pipe, wherein an outlet of the pulping chamber is connected with the output pipe, and the return pipe is connected with the output pipe. The pulping machine further comprises an on-line pulp consumption detector, an on-line pulp return capacity detector, a return pipe control valve and an output pipe control valve; the on-line pulp consumption detector and the on-line pulp return capacity detector are used for detecting the pulp consumption and the pulp return capacity on line respectively; the return pipe control valve and the output pipe control valve are installed on the return pipe and the output pipe and used for controlling the pulp return capacity and the pulp consumption respectively; the return pipe control valve is controlled according to the detected pulp return capacity, and the output pipe control valve is controlled according to the detected pulp consumption. The pulping machine is low in vibration and high in beating degree.

Description

technical field [0001] The present invention relates to a paper machine, in particular to a refiner in a paper machine. Background technique [0002] The energy consumption of paper machine long fiber refining is calculated and controlled by the consumption of long fiber. Refining energy consumption is lower when long fiber consumption is low. At the same time, the supplier of the refiner sets the maximum refining energy consumption for the refiner, for example, the maximum refining energy consumption is 130Kwh / t, which leads to when the long fiber consumption is lower than the predetermined value, for example, less than 25L / t s, the beating degree of long fibers will be very low, about 23°SR, even if the refining energy consumption is increased, the beating degree cannot be further improved. Contents of the invention [0003] The purpose of the present invention is to increase the beating degree of long fibers and keep the energy consumption of long fibers in a controll...
