Described stove gate device 23 also can be arranged in low temperature oven 30.During experiment, in normal temperature stove 40, sample weighing is good, utilize lift drive mechanism 52 to be placed with setting-out dish 56 jacking of crucible 563, enter low temperature oven 30 be arranged on the stove gate device in low temperature oven 30 by this after and test.
The whole course of work of this industrial analysis instrument is: open low temperature fire door 33, the crucible 563 that sample is housed is placed on setting-out dish 56 successively, rotating drive mechanism 54 drives setting-out dish 56 to rotate to each fixed angle at the same time, makes crucible 563 aim at sample weighting rod 63.Often go to an angle, lift drive mechanism 52 drives setting-out dish 56 to decline, and is placed in by corresponding crucible 563 on sample weighting rod 63 and weighs.Setting-out dish 56 rises afterwards, and crucible 563 leaves sample weighting rod 63 and gets back on setting-out dish 56, and setting-out dish 56 rotates to next angle, starts the weighing of next crucible 563.After whole weighing completes, lift drive mechanism 52 drives pillar 57, setting-out dish 56 is driven to rise until the locator card inductor 5213 of the second locating device 521 of lift drive mechanism 52 corresponds to high temperature locator card 5211 stops rising, the drive unit 232 of stove gate device 23 drives stove gate device 231 to open simultaneously, setting-out dish 56 all enters in high temperature furnace 20, closed fire door 231, and pillar 57 is through the accommodation hole 2315 at fire door 231 center, high temperature furnace 20 is sealed, and sample heats in high temperature furnace 20.After having heated, fire door 231 is opened, and setting-out dish 56 drops to low temperature oven 30, opens low-temperature heater 32 pairs of samples and carries out insulation also as said method weighs.After cooling, take out sample.
Utilize industrial analysis instrument of the present utility model, multiple crucible can be placed on setting-out dish and rise to high temperature furnace from low temperature oven by lift drive mechanism simultaneously, and drop to low temperature oven from high temperature furnace simultaneously, therefore can realize multiple crucible to heat simultaneously, improve conventional efficient, and multiple crucible enters simultaneously and leaves high temperature furnace, therefore the heat time of multiple crucible is identical, namely the experiment condition of all samples is identical, ensure that the accuracy of experiment.Simultaneously, in prior art, generally at normal temperature stove, the sample before experiment is weighed, after having tested, separately establish one to sample mechanism in low temperature oven and weigh sample, therefore be adopt the different mechanisms that samples to weigh before and after its experiment, because difference samples the difference of mechanism, will inevitably impact measurement result.In the present invention, owing to sampling organization establishes in normal temperature stove, and its sample weighting rod stretches into low temperature oven, before and after therefore testing, is adopt the same mechanism that samples to weigh sample, further increases the accuracy of measurement.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
