Unobstructed in order to ensure the sample transfer between preanalysis storehouse 1 and sample analysis storehouse 5, connected by transmission channel between the first valve 4 and sample analysis storehouse 5, the sidewall of transmission channel is communicated with multiple purging air valve 8, 9, multiple purging air valves 8, 9 along transmission channel sidewall order arrangement, in order to ensure that residual coal sample cleaning effect in transmission channel is more preferably, one end preferably in one end near the first valve 4 of transmission channel with near sample analysis storehouse 5 is respectively provided with at least one and purges air valve 8, 9, so that the residual coal sample purged can be discharged quickly through transmission channel.
In order to prevent transmission channel from blocking, the auto injection of the present embodiment is abandoned sampling device and is also included abandoning sample pipe, the one end abandoning sample pipe connects with preanalysis storehouse 1 by abandoning sample tube inlet 19, the other end connects with abandoning sample mouth 21 by abandoning sample pipe outlet 20, preferably abandoning sample pipe is transparent material, when transmission channel blocks, sample in preanalysis storehouse 1 can abandon sample mouth 21 either directly through abandoning the arrival of sample pipe, it is then discharged out outside device, so can see there is sample through out-of-date in sample pipe intuitively when abandoning, can judge that transmission channel is blocked immediately, such that it is able to stop the sample introduction process of test automatically, so that on-call maintenance transmission channel.
The auto injection of the present embodiment is abandoned sampling device and is by the sample introduction of automatization and abandons sample and realize the situation of change of real-time online detection ature of coal, will be introduced briefly the sample introduction of automatization and abandon sample flow process below:
The coal sample of 13mm granule size is made the coal sample of 0.2mm granule size through sample preparation module, and the coal sample of 0.2mm granule size is transmitted to preanalysis sample bin 1 further through the mode of pneumatic transfer.
By the sample levels of accumulation in sensor 10,11 in real time monitoring preanalysis storehouse 1, if sensor 10,11 sample size monitored in preanalysis storehouse 1 runs up to enough it is analyzed, then sensor 10,11 is notified that control system stops sampling.
After the original sample analysis in sample analysis storehouse 5 is complete, and the sample in sample analysis storehouse 5 is drained, so system can close the second valve 7, then the first valve 4 is opened, open breather valve 2 to ventilate, produce pressure differential, and then make the sample in preanalysis storehouse 1 fall in sample analysis storehouse 5, then turn on purging air valve 3 ventilation and purge preanalysis storehouse, open purging air valve 12 and purge the door place (i.e. the first valve place) in preanalysis storehouse, purge clean rear closedown the first valve 4 and purge air valve 2,3,12, starting the analysis sample gathered next time.
After sample in preanalysis storehouse 1 falls completely within sample analysis storehouse 5, sensor 16 can monitor the number of sample size in sample analysis storehouse 5, in time reaching q.s, sample in sample analysis storehouse 5 is just analyzed by xrf analysis instrument by analysis measurement window 6, and analyzing measurement window 6 in the process analyzed can keep smooth by the adsorption of vacuum valve 14.
Sample in sample analysis storehouse 5 analyzed complete after, system is opened the second valve 7 and is discharged by abandoning sample mouth 21 by the sample in sample analysis storehouse 5, and open purging air valve 8,9 purging transmission channel, open purging air valve 13,15,17 and purge sample analysis storehouse 5, open purging air valve 18 and purge door place and the second valve place in sample analysis storehouse, purge and close the second valve 7 after totally respectively and purge air valve 8,9,13,15,17,18；
Repeat said process, until the whole automatic on-line of sample is completed.
In actual use procedure, the transmission channel occasional blockage phenomenon between preanalysis storehouse 1 and sample analysis storehouse 5, the handling process after blocking generation is as follows:
The sample preparation module that the coal sample of 13mm granule size is passed through this system makes the coal sample of 0.2mm granule size, and the coal sample of 0.2mm granule size is transmitted to preanalysis storehouse 1 further through the mode of pneumatic transfer；
Sensor 10,11 can monitor the sample levels of accumulation in preanalysis storehouse 1 in real time, if sensor 10,11 sample size monitored in preanalysis storehouse 1 runs up to enough is analyzed, then sensor 10,11 is notified that control system stops sampling.
After the original sample analysis in sample analysis storehouse 5 is complete, and the sample in sample analysis storehouse 5 is drained, then system can close the second valve 7, then the first valve 4 is opened, open breather valve 2 to ventilate, produce pressure differential, and then make the sample in preanalysis storehouse 1 fall in sample analysis storehouse 5.
If the transmission channel between preanalysis storehouse 1 and sample analysis storehouse 5 there occurs blocking, the coal sample in preanalysis storehouse 1 then can abandon sample tube inlet 19 by connection and the transparent plastic pipeline (namely abandoning sample pipe) abandoned between sample pipe outlet 20 discards.
If abandoning in sample pipe and having coal sample, then the passage illustrated between preanalysis storehouse 1 and sample analysis storehouse 5 there occurs blocking, it is necessary to this auto injection is abandoned sampling device and safeguards.
The auto injection of the present embodiment is abandoned sampling device and is had the advantages that
1, the vertical perpendicular arrangement design in preanalysis storehouse 1 and sample analysis storehouse 5, the action of gravity of sample self can be taken full advantage of, sample is made vertically to fall in sample analysis storehouse 5 from preanalysis storehouse 1, so that the sample piled up in sample analysis storehouse 5 has good uniformity, stability is measured in the analysis improving device；
2, preanalysis storehouse 1 has been respectively mounted two sensors 10,11, the collection of energy monitor in real time sample size, just can stop the collection of sample after reaching enough amounts；Sample analysis storehouse 5 is equipped with sensor 16, for detecting whether the coal sample amount analyzed in storehouse is enough once analyzed；
3, purging arranging of air valve 3,8,9,12,13,15,17,18 can realize the internal regional of whole device is purged, to reduce the coal sample of device internal residual, measuring, thus improving, the accuracy analyzed.
4, it is mounted with breather valve 2 at the top in preanalysis storehouse 1, it is possible to avoid the occurrence of preanalysis storehouse 1 hatch door and open the situation that rear sample does not fall.
5, analyzing measurement window 6 is a strip window, which increases the cross-sectional area that sample is analyzed, and then improves analysis precision.
6, analyze the back of measurement window 6 equipped with a vacuum valve 14, be used for producing adsorptive pressure, make analysis measurement window 6 keep smooth state；
7, analyze measurement window 6 can conveniently dismantle, it is possible to realize regular replacing easily and analyze measurement window 6；
8, being connected with the door lower end in sample analysis storehouse 5 door lower end, preanalysis storehouse 1 by a transparent plastic tube (namely abandoning sample pipe) between preanalysis storehouse 1 and the sample analysis storehouse 5 of the present embodiment, user can very easily by the situation in this transparent plastic tube judges whether block in transmission channel.
