Analysis On The Pulping Process Of Papermaking Toilet Paper

When the pulping process of the papermaking toilet paper machine begins to add water, the flow rate measured by the flowmeter begins to be cumulatively calculated, and is determined according to the formula of / water addition amount (pulp weight x pulp plate dryness) / concentration - pulp plate weight 0 The amount of water added to the pulp and the slurry.

The main process parameters to be controlled in the pulping process are the concentration, time and concentration of the pulp. The concentration and time of the pulp determine the degree of slurries of the slurry, and the concentration of the paper machine in the toilet paper machine is the basic condition for the next step of refining.

When the pulp plate is lowered into the starting pulping tank and the accumulated flow rate is equal to the calculated amount of water added to the pulp, the automatic watering valve is closed and the pulping time is calculated, which can be easily realized by a timer or in a DCS program.

After the set time has elapsed, the automatic valve is opened to add water until the accumulated flow rate is equal to the calculated amount of water added to the slurry, and at the same time, the slurry is pumped, so that a stable concentration of the slurry can be obtained in the slurry tank.
