    摘要： An apparatus and method for removing dense impurities, such as sand, from a fluid, such as liquids use in the production of cellulosic pulp. A vertically upstanding tank substantially circular in cross-section is provided including a top wall, bottom wall, and side wall. The fluid with dense impurities is introduced into the tank with a whirling motion. Vertical stagnation of the dense impurities against the side wall interior (which can result in damage to the tank wall) without dampening the whirling motion imparted to the fluid is prevented by mounting a perforated funnel in the tank at the area of the tank where the vertical stagnation is likely to occur.
