Description
Technical field
The present invention is mainly concerned with the surveying instrument field of analyzing the combustible constituent content, refers in particular to a kind of gas analyzer with automatic sample feeding mechanism.
Background technology
Except that containing part dirt and water, all the other all are organic substances in the combustible.Organic substance mainly is made up of five kinds of elements such as carbon, hydrogen, oxygen, nitrogen, sulphur again in the coal, they are one of indexs of coal science classification, can also be used to calculating the thermal value of coal, the low-temperature pyrolysis product of estimation and forecasting coal is a basic foundation of estimating combustible mass.These main five kinds of constituent contents are to realize by the content that detects burning back gas interior element in the analysis combustible, so the surveying instrument of this type can be referred to as gas analyzer.
Some ultimate analysis has the requirement of comparison strictness to burning situation in the gas analyzer, as hydrogen.Because of containing a large amount of steam in the air, wherein contained protium can produce very big influence to test result, therefore will guarantee the sealing in the flame tube when burning, and insufficient gas that has air or other to contain protium enters.Referring to shown in Figure 1, in the existing testing tool, the flame tube more than 3 in the analytical furnace 1 adopts the U-shaped pipe, and its two ends respectively has one combustion-supporting oxygen air intake opening and burning back gas outlet is provided, and crucible 2 then is placed in the flame tube 3.Because every crucible 2 is taken out changed once, just whole gas circuit need be carried out once flushing, discharge and change other gas that crucible is sneaked into because of getting, get as if crucible 2 that to change frequency too high, the consumption of oxygen that can be used in flushing is very big, causes unnecessary waste.For preventing that other gas from entering flame tube 3, guarantee the continuity of experiment, crucible 2 is not take out flame tube 3, but by the injection port of U-shaped pipe upper end coal sample is fallen into crucible 2 internal combustion; After the experiment number reaches certain quantity, again the sampling device of analytical furnace 1 top is taken off, manually crucible 2 is taken out with tweezers, more renew crucible 2.There is certain defective in this mode of getting crucible: (1) analytical furnace is a high-temperature service, and hot gas is toward the upper reaches, so the temperature of the sampling device on the analytical furnace can not directly contact with hand often than higher.Therefore analytical furnace need be stopped to heat up when getting sampling device, treat that sampling device cools down to operate that this has just delayed the time again, work efficiency is not high.If do not lower the temperature, then will be by other tool operation, very inconvenient.(2) flame tube is that resistant to elevated temperatures material is made, and fragility is big, and price is expensive, and is fragile.When getting crucible,, must get in touch manufacturer and ask the technical professional to operate and change flame tube if artificial undue force damages flame tube possibly.Therefore, this has not only influenced applying unit and has normally chemically examined carrying out of work, has also increased the maintenance cost of instrument.(3) the high-temperature service manual operations very easily makes the user be scalded not hommization.
