Slurry sampling device and method

A slurry sampling device for sampling a slurry in which solid particles are dispersed, comprising:

• an upper block and a lower block in relative spaced relationship to provide a space therebetween;
• a rotator for collecting samples rotatably mounted in said space between said blocks;
• a plurality of through holes in said rotator each having a volume corresponding to the amount of sample to be collected;
• slurry conduit means in said upper and lower blocks having inner ends contacting said rotator for selective communication with said through holes to facilitate flow of slurry through said slurry conduit means;
• carrier fluid conduit means in said upper and lower blocks having inner ends contacting said rotator for selective communication with said through holes to facilitate flow of carrier fluid through said carrier fluid conduit means;
• and
• arc-shaped grooves on portions of said upper and lower blocks communicating with said slurry conduit means where said inner ends of said slurry conduit means contact said rotator so that rotation of said rotator alternately connects at least one of said through holes with said slurry conduit means through said arc-shaped grooves and with said inner ends of said carrier fluid conduit means for transferring a sample from said slurry conduit means to said carrier fluid conduit means, and at all times at least one of said through holes is in contact with said grooves.
