Abstract: 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.

Abstract: The present invention relates to an apparatus for treating a solution or a slurry solution and its improved types. The apparatus of the present invention comprises a hollow rotating shaft having a sealing mechanism and a rotating mechanism at upper portions thereof, the apparatus being characterized by comprising a plurality of stirring branch pipes attached to the lower end of the hollow rotating shaft vertically downward extending into the solution in a storage tank, and a plurality of gas jet pipes disposed under the respective branch pipes, the gas jet pipes extending vertically downward and being opened at the lower ends thereof, whereby the shaft and the stirring branch pipes are rotated, while a gas is jetted from openings of the gas jet pipes through the sealing mechanism, the hollow rotating shaft and the branch pipes.
