Fig. 4 is the structural representation that after the utility model the second sample feeding rod rises, crucible enters oxidation furnace.
Embodiment
As shown in Figure 1, 2, the efficient feed arrangement of a kind of rock sample of the utility model, comprise rotating disk 1, crucible 2, stool 3, stepper motor 4, sample feeding rod and driving cylinder, wherein, uniformly on rotating disk 1 offer a plurality of through holes 11, and each through hole center line is all equal to the distance of center of turntable axis, and each through hole 11 correspondence is provided with a stool 3 and a crucible 2; The rotation of rotating disk 1 is driven by stepper motor 4.
Wherein, above-mentioned stool 3 comprises installs pedestal 31 and for placing the support pedestal 32 of crucible, on installation pedestal 31, offer the cavity 33 adapting with sample feeding rod upper end size, supporting the gas pipeline 34 that also offers connection cavity on pedestal, the gas outlet of gas pipeline 34 is arranged on the upper end face that supports pedestal 32.On the top that pedestal 31 is installed, be outward extended with an edge clipping 35, edge clipping 35 tops are provided with high-temperature resistant seal ring 36.High-temperature resistant seal ring 37 is installed above cavity 33; High-temperature resistant seal ring 36 on edge clipping 35 and the high-temperature resistant seal ring 36 in cavity 33 are carbon seal ring.
Above-mentioned sample feeding rod comprises the first sample feeding rod 5 and the second sample feeding rod 6, offers for passing in admission line 51, the second sample feeding rod 6 of carrier gas (nitrogen) and offer for passing into the admission line 61 of oxic gas (air) in the first sample feeding rod 5.Drive cylinder to comprise the first cylinder 52 and the first cylinder 62.The installation site of the first sample feeding rod 5 and the second sample feeding rod 6 is corresponding with the import of pyrolysis oven 7 on rock pyrolysis instrument and oxidation furnace 8 respectively.Concrete, the first sample feeding rod 5 and the second sample feeding rod 6 be arranged on the below of rotating disk 1 and respectively with rotating disk on adjacent two through holes be coaxially set; The first sample feeding rod 5 can rise under the driving of the first cylinder 52, by being placed on sample in crucible 2, sending into pyrolysis oven 7 and carries out pyrolysis processing; The second sample feeding rod 6 can rise under the driving of the first cylinder 62, and sample is sent into and in oxidation furnace 8, carried out oxidation processes.
