Title: Method for measuring moisture of powder
Inventor: HASEGAWA SHINICHI
IPC: G01N25/66
Filed: 1985-11-15
Abstract: PURPOSE:To measure the moisture of a powder, by supplying dry gas in a grinder for preparing the powder and measuring the water content of gas exhausted from the grinder. CONSTITUTION:Uranium oxide in a hopper 1 is successively transferred into a grinder 3 by a screw feeder 2 driven by a motor 4. Simultaneously with this, dry nitrogen gas is continuously supplied into the grinder 3 from a supply source through a flowmeter 8 and uranium oxide is ground in the grinder 3 within a nitrogen atmosphere to be converted to an uranium oxide powder. At this time, the internal temp. of the grinder 3 is raised by heat generated by grinding work. Because uranium oxide and dry nitrogen oxide are stirred by the grinder 3, a part of the moisture contained in the uranium oxide stock material can be caught by the nitrogen gas. Further, the uranium oxide powder is discharged from the lower part of the grinder 3 and transferred to the next process by a screw feeder 6. The nitrogen gas containing moisture is exhausted from the grinder 3 through an exhaust pipe 9 to be sent to a filter 10 and the uranium oxide powder is removed by the filter 10 while the gas is exhausted 11 from an exhaust line.

Abstract: PROBLEM TO BE SOLVED: To prevent moisture adsorption and to prolong the service life of a filter by arranging the filter for partitioning a dust collecting chamber and a cleaning chamber and decreasing the opening degree of an air volume control damper to a lower limit when the pressure difference between the dust collecting chamber and the cleaning chamber detected by a detecting mechanism exceeds the set upper limit. SOLUTION: When dust is collected, an air volume limiting damper 31 is opened, the opening degree of an air volume control damper 32 is increased, an exhauster 30 is operated, and the dust is collected by a dust collector 20. A first controller 71 is simultaneously actuated to send an opening or closing signal to a stop valve 28 to inject compressed air from respective nozzles 25, and the dust is collected and the filter is cleaned at the same time. At this time, when the dust contains moisture, a signal of the pressure difference between the dust collecting chamber 21 and the cleaning chamber 22 is sent to a second controller 72 from a differential pressure gage 27a, the opening degree of the air volume control damper 32 is minimized when the pressure difference exceeds the set upper limit, and the air volume in a pipeline 34 is decreased.  Subsequently, the opening degree of the damper 32 is maximized when the pressure difference is decreased below the lower limit.
