The first motor 22 drives the driving gear 23 to rotate, and the rotation of the driving gear 23 drives the driven gear 24 to rotate. The rotation of the driven gear 24 drives multiple feed barrels 27 to rotate. The rotation of multiple feed barrels 27 discharges bubbles from the materials through centrifugal force, and the gas accumulates at the top of the feed barrel 27. At this time, a vacuum pump is connected through the input port 272 to extract the gas, and the large particles of impurities and bubbles in the pulp are removed by centrifugal force, so that the pulp is purer, which is beneficial to the production of paper.
