Embodiment 1
In the automatic mercury vapourmeter of the embodiment, as shown in figure 8, crucible 101 is placed in the locating slot of setting-out rotating disk 21.
First, straight-line motion mechanism 1 is in leftmost bit, and the top board of elevating mechanism 3 is in lowermost position.As shown in figure 9, by elevating mechanism 3
Drive top board to rise, crucible 101 is ejected setting-out rotating disk 21, at this moment again as shown in Figure 10, travelled forward by straight-line motion mechanism 1
To sample position is connect, after crucible 101 by the support of sample presentation pin 11, it is achieved thereby that crucible 101 is shifted from the locating slot of setting-out rotating disk 21
Arrive on sample presentation pin 11.
Then as shown in figure 11, elevating mechanism 3 declines playback to origin-location, the sample presentation pin 11 on straight-line motion mechanism 1
Crucible 101 is ask to be burnt in sending into the catalysing tube 4 of combustion furnace 5, while the end face of sample presentation pin fixed seat 21 connects with catalysing tube 4
Touch and form sealing.
Heating is burnt in combustion furnace 5, in the presence of catalyst, is discharged in the mercury element burning in coal sample,
Generation mixed gas, mixed gas are entered in neatization component 6 by the tail end of combustion furnace 5, are acted in the gold tube of neatization component 6
Under, the mercury element in mixed gas is absorbed, and after after the discharge of other gases, the heating of neatization component becomes the mercury element of absorption
Into steam, measured into detection cell 8, measurement feedback is to control system.Gas after measurement is arranged by waste discharge gas port
Go out.Its gas circuit is connected with silicone tube.
Straight-line motion mechanism 1 is returned to and connects sample position, and elevating mechanism 3 now rises (the state such as Figure 10 of jack-up crucible 101 again
It is shown).Straight-line motion mechanism 1 continues to retract to original position, now realizes that crucible is transferred to the top of elevating mechanism 3 from sample presentation pin 11 again
On plate 32 (as shown in Figure 9), elevating mechanism 3 heads on crucible 101 and declines together, until crucible 101 is put into setting-out rotating disk 21
In locating slot, while elevating mechanism 3 also declines playback to origin-location state (as shown in Figure 8).So complete a coal sample certainly
Dynamic burning, analysis process.
When the test of next coal sample is prepared, control system 10 sends instruction, the motor 24 on turn-plate type sample-sending 2
Start working, driving transmission device 23 so that drive setting-out rotating disk 21 around annular guider 26 hollow center rotate, when turn
After dynamic certain angle, indexing means 22 will sense printing opacity and lighttight signal, feed back to control system 10, controlled motor 24
Be stopped, and now setting-out rotating disk 21 just rotates crucible position, then is risen by elevating mechanism 3, repeats said process,
Complete second automatic testing process of coal sample.By that analogy, multiple coal samples are completed continuously to test automatically.
Each embodiment is described by the way of progressive in this specification, and what each embodiment was stressed is and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.Finally, the method for the present invention is only
Preferably embodiment, is not intended to limit the scope of the present invention.It is all within the spirit and principles in the present invention, made
