Title: Convection preventing apparatus for infrared heating dry type moisture meter
Inventor: NAKAGAWA HIROMI
IPC: G01N5/04
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To prevent the operation of convection for a sample tray with reduced air flow rate by the convection of an inner cylinder by increasing the air flow rate due to the convection of a gap between the inner cylinder and an outer cylinder. SOLUTION: The outer diameter of the upper end 31 of a skirt part 30 is reduced from the inner diameter of an outer cylinder 20, a gap 32 is provided, and an inner cylinder is held via gaps 41, 42 coaxially with an outer cylinder 20 and the part 30. When an infrared lamp L is fired, a convection occurs by heating, and its air flow causes the gap 41 with the inner cylinder and finally is exhausted from a ventilation port 23. The air by the convection is introduced from the lower end 35 of the part 30 via the gap 42 and from the gap 32 of the exterior.  Particularly, the air from the gap 32 is almost passage through the gap 41, the air flow by the convection is increased in the gap 41 to cool the outer wall of the inner cylinder, and hence the air flow by the convection in the inner cylinder is minimized, and the air flow by the convection via the sample tray S and a hood 50 can be remarkably reduced. Accordingly, the tray S can be always mounted on a balance base 12 in the stable state.
