Description
Technical field
The utility model relates to experimental provision field, is specifically related to a kind of tripod for ash determination.
Background technology
Laboratory is when working sample ash, it is generally the crucible by putting into constant weight after sample weighing, again crucible crucible tongs are put on electric hot plate/Electric stove one by one, crucible cover is half-open, by the sample charing in crucible, after charing is good again with crucible tongs by its one by one put on enamel pallet, with crucible tongs, crucible is transferred to high temperature furnace ashing one by one more subsequently, after sample ashing, then crucible is taken out one by one put into drier, weigh after cooling.
In aforesaid operations process, because crucible in processing procedure can not catch tactile, repeatedly must move, waste time and energy with crucible tongs, crucible easily slides from crucible tongs and breaks into pieces, and crucible is easily placed shakiness and fallen down, and causes the failure of an experiment.Secondly, when crucible is placed on carbonization and ashing, partly crucible lid must be opened wide, and crucible disequilibration, easily fall, strengthen the risk of the failure of an experiment.In a word, whole operation, wastes time and energy, having a big risk of ash determination the failure of an experiment.
Utility model content
The purpose of this utility model is just to provide a kind of tripod for ash determination, and it can effectively solve the problem, and simplifies the operation of crucible movement, reduces the risk of ash determination the failure of an experiment.
For achieving the above object, the utility model have employed following technical scheme:
A kind of tripod for ash determination, it is characterized in that: it is pottery/quartz glass formation, comprise circular gripper shoe, gripper shoe offers uniformly the fixing hole for fixing crucible, the aperture of fixing hole is consistent with the designated diameter of crucible, described designated diameter is the crucible external diameter at crucible height 5/8 place, the periphery in gripper shoe lower side panel face evenly arranges feet, the periphery, epipleural face of gripper shoe arranges the support ear being used for tripod and carrying out stacking, support ear is corresponding with feet to be arranged, and the height sum of crucible and crucible cover is less than the height of tripod.
Feet is that circular body is formed after its Bottoming semicircle, and support ear is provided with two, support and on offer square hole; The height of crucible is 4.0cm, and the height of crucible cover is 1.7cm, and in gripper shoe, the aperture of fixing hole is 3.9cm, and be 2.5cm to the height of gripper shoe upper face bottom tripod, the height of support ear is 3.5cm, and crucible is cone tubular.
Above-mentioned tripod is adopted to fix crucible, tripod can stack, tripod and crucible can together be placed in electric hot plate/Electric stove and high temperature furnace carries out carbonization and ashing, reduce the number of times of crucible movement, and ensure that crucible is steadily placed, improve test efficiency and reduce the failure of an experiment risk.

Detailed description of the invention
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, the utility model is specifically described.Should be appreciated that following word only in order to describe one or more concrete embodiments of the present utility model, considered critical is not carried out to the protection domain that the utility model is specifically asked.
The technical scheme that the utility model is taked is as Fig. 1, 2, 3, shown in 4, a kind of tripod for ash determination, it is refractory material formation, comprise circular gripper shoe 11, gripper shoe 11 offers uniformly the fixing hole 11a for fixing crucible, the aperture of fixing hole 11a is consistent with the designated diameter of crucible, described designated diameter is the crucible external diameter at crucible height 5/8 place, the periphery in gripper shoe 11 lower side panel face evenly arranges feet 13, the periphery, epipleural face of gripper shoe 11 arranges the support ear 12 being used for tripod and carrying out stacking, support ear 12 is corresponding with feet 13 to be arranged, crucible 21 is less than the height of tripod with the height sum of crucible cover 22.
Above-mentioned tripod is adopted to fix crucible, tripod can stack, tripod and crucible can together be placed in electric hot plate/Electric stove and high temperature furnace carries out carbonization and ashing, reduce the number of times of crucible movement, and ensure that crucible is steadily placed, improve test efficiency and reduce the failure of an experiment risk.
Concrete scheme is: described refractory material is pottery/quartz glass; Feet 13 is formed after its Bottoming semicircle 13a for circular body, and support ear 12 is provided with two, and support ear offers square hole; The height of crucible is h1+h2=4.0cm, and the height of crucible cover is h3=1.7cm, and the aperture of the diameter D1=13.5cm of gripper shoe 11, fixing hole 11a is D2=3.9cm, designated diameter D3 D3=D2=3.9cm identical with the aperture of fixing hole 11a.Be H2=2.5cm to the height of gripper shoe 11 upper face bottom tripod, the height of support ear 12 is H1=3.5cm, and crucible is cone tubular, specifically as shown in Figure 1,2,3, 4.
Ceramic high-temperature resistant (1410 DEG C), quartz glass is high temperature resistant (1050 DEG C), and this bi-material also has the advantages such as corrosion-resistant, ph stability good, soluble impurity is few, the coefficient of expansion is little.Wherein pottery because of cheap be first-selection.
Support ear 12 being offered square hole is conveniently taking for the ease of tripod, no matter carbonization on the high electric hot plate of temperature or Electric stove, or ashing in high temperature furnace, support ear 12 temperature after carbonization and ashing also can corresponding height, clamping support ear 12 with crucible pricker through square hole when taking moves relatively more firm, not easily landing.
The height of support ear 12 is set to H1=3.5cm, because the height of crucible is h1+h2=4.0cm, the height of crucible cover is h3=1.7cm, the total height of crucible and crucible cover is h1+h2+h3=5.7cm, fagging 11 is to crucible bottom h1=2.5cm, therefore, when tripod superposes, the height H 1 of support ear 12 must be greater than 3.2cm (h2+h3), and the cavity volume of high temperature furnace and drier is limited, support ear can not be allowed too high, therefore the height of support ear 12 is preferably set to H1=3.5cm, so just can superpose stacking in high temperature furnace, batch test sample.
The height setting of feet 13, it can not be greater than crucible and embed height in gripper shoe 11, otherwise crucible is just unsettled by tripod and can not be attached to and carry out heating on Electric stove or on electric hot plate and carbonize, therefore H2≤h1, the height of feet 13 is preferably set to 2.5cm.
When using the utility model to operate, or need half to open wide crucible lid, lid opens about 1/3, and crucible lid slightly can superpose annular and place.As shown in Figure 5.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; to know in the utility model after contents; under the prerequisite not departing from the utility model principle; can also make some equal conversion to it and substitute, these convert on an equal basis and substitute and also should be considered as belonging to protection domain of the present utility model.
