    • A slurry sampling device (3) for sampling a slurry in which solid particles are dispersed has upper and lower blocks (105, 109), and a rotator (102) for collection which is rotatably held between the blocks and has a plurality of through holes (111) each having a volume corresponding to the amount of sample to be collected. The upper and lower blocks are provided with slurry conduits (101, 108) and carrier fluid conduits (107, 110) which can be communicated with the through holes so that slurry and carrier fluid can flow therethrough. Arc-shaped long grooves (113, 114) are provided on portions of the upper and lower blocks where ends of the slurry conduits (101, 108) come into contact with, or are adjacent to, the rotator, so that at least one of the through holes is thereby constantly in contact with the long grooves. In the method for sampling slurry a part of the slurry is pumped (2) from a slurry tank (1) and returned (4) to the slurry tank, and that part of the slurry is sampled intermittently by the sampling device (3) and sent to an analyzer (6) for analysis of the composition of the slurry.
    • 用于对其中分散有固体颗粒的浆料进行取样的浆料取样装置(3)具有上下块(105,109)和用于收集的旋转体(102),其被可旋转地保持在块之间并具有多个通孔 (111),每个具有对应于要收集的样品量的体积。 上部和下部块设置有可与通孔连通的浆液管道(101,108)和载体流体管道(107,110),使得浆料和载体流体可以流过其中。 在上部和下部块的部分上设置有弧形的长槽(113,114),其中浆料管道(101,108)的端部与旋转体接触或相邻,使得至少一个 因此通孔与长槽不断地接触。 在采样浆料的方法中,将一部分浆料从浆料罐(1)泵送(2)并返回(4)到浆料罐中,并且该部分浆料被取样装置(3)间歇地取样, 送到分析仪(6),分析浆料的组成。
