Abstract: 1,044,127. Sampling granular material. CENTRAL ELECTRICITY GENERATING BOARD. May 31, 1965 [June 1, 1964], No. 22611/64. Heading B8N. A device for sampling granular material, such as grit in a flue, comprises rotary wheels 16 17 having blades 18 for dividing first and second chambers 14, 15 into a number of sections, the two wheels 16 being driven by a motor 23 so that each section in the first chamber is in communication with an inlet 24 and, subse quently, with a passage 25 connected with the second chamber and each section in the second chamber is in communication with the passage 25 and subsequently, when isolated from the connecting passage, in communication with an outlet passage 27. The chambers 14, 16 are formed in casings 11, 13 and the passage 25 in a plate 12, the three parts being secured together to form a unit. In operation, grit falls through the inlet 24 into one of the sections in the chamber 14. As the wheel 16 rotates the grit falls through the passage 25 into a section in the chamber 15, the latter sections having a quarter of the capacity of the sections in the upper chamber 4. Further rotation of the wheel 17 causes the filled section to be closed-off from the passage 25 and the grit pushed by a blade into the outlet 27 where it is fed to an analyser. As the wheels continue to rotate the excess grit in the section of the chamber 14 falls through a passage 26 in the plate 12 to a second outlet passage 28 and then to waste.
