Embodiment
Below, show preferred implementation of the present invention.Fig. 1 is the cut-open view that is used for illustrating the device that uses in the damaged detection method of saggar of the present invention, and Fig. 2 is the figure that is used for the user mode of key diagram 1 shown device, and, in each accompanying drawing, 1 expression negative pressure space forms the unit, 2 expression air injection units, 3 expression covers, 4 expression saggars.
Through the powder in the saggar that takes out from the other end of firing furnace behind the firing process, the upset by saggar, come to be reclaimed from saggar 4 by the methods such as suction of powder aspirator.As shown in Figure 1, reclaimed the empty boxes alms bowl 4 behind the powder and be configured in the top that negative pressure space forms the back up pad 12 of unit 1, and the peristome of this empty boxes alms bowl 4 down.The peristome that negative pressure space forms unit 1 and saggar 4 has sandwich seal 5 structure of driving fit mutually.Negative pressure space forms the funnel-form that is shaped as of unit 1, has air pump unit 11 in the upper end, has powder escape hole 13 in the bottom.In addition, negative pressure space forms unit 1 and has air injection units 2 such as air nozzle in the inner space, can utilize the internal spray air of this air injection unit 2 to saggar 4.
Air injection unit 2 has by air packing 22 can form the structure of the inner space slip of unit 1 in negative pressure space, and has the cylinder 21 that is used to realize slide.
In the present invention, as shown in Figure 1, form the back up pad 12 upper supports configuration saggar 4 of unit 1 in negative pressure space, and this above back up pad 12 setting can hold the cover 3 of saggar, this cover 3 is by seal 5 and this back up pad 12 driving fit mutually.Utilize air pressure determination unit 31 to measure the interior pressure of cover.
