Abstract
Description
Technical Field
[0001] The invention relates to the technical field of phase change materials, and in particular to a portable combined crucible placement box and a use method thereof. Background Art
[0002] Crucibles are widely used in chemical experiments such as strong heating and calcining solids. Crucibles of different materials can be selected according to the properties of the solid to be heated, such as porcelain, graphite, quartz, zirconium oxide, iron, nickel, platinum, etc. For metal crucibles such as platinum, during use, they are generally numbered and distinguished by stamping the crucible wall. The stamped numbers are sometimes difficult to distinguish, and as the use time increases, the stamps gradually become lighter and cannot be distinguished.
[0003] The main purpose of the crucible stand is to support the weight of the crucible. Commonly used crucible stands are mainly made of ceramic or metal nickel, which can withstand high temperature and corrosion, but have no handle and a simple structure, and only have a fixing function. This is not convenient in actual use. First, the crucible itself can only be distinguished by the steel stamp. When placed on a conventional crucible stand, it is necessary to confirm the order of picking up and putting down one by one, and the conventional crucible stand is centrally symmetrical. After it is full of crucibles, it is easy to confuse the placement direction, affecting the experimental efficiency; secondly, the conventional crucible stand has no handle, which is not convenient for moving the whole crucible; thirdly, although the crucible is equipped with a lid, the lid only serves as a covering, and there is a possibility of slipping as the crucible moves, which will cause contamination to the sample in the crucible; finally, the conventional crucible stand does not have the function of real-time display of the crucible temperature, which affects the arrangement of subsequent experimental work and the accuracy of the experimental results.

[0049] Example 3
[0050] This embodiment introduces the method of use based on Embodiments 1 and 2.
[0051] Taking the pretreatment method of soil samples in the Nuclear Industry Ministry Standard EJ / T 192.3-82 "Analysis Method for Fluoride Content in Environmental Sample Soil" as an example, the use of the portable combined crucible placement box is explained:
[0052] Open the lid 1-2 of the stainless steel outer box 1, select the corresponding transfer support frame 2 and writing hole plate 3 according to the capacity of the crucible to be used, confirm that the direction mark 7 on the transfer support frame 2 is horizontally forward, and then put it into the stainless steel outer box 1, with the vertical support legs 2-4 facing downward, and the transfer handles 2-2 at both ends extending through the long holes 1-3 at both ends of the outer box, and then stack the writing hole plate 3 on the transfer support frame 2, with the legs 3-3 facing downward. Take a nickel crucible to weigh the soil sample and put it into the support hole 2-3, add sodium hydroxide solution, use the whiteboard pen in the pen box 6 on the outer box 1 to write the number information of the sample in the crucible on the writing whiteboard 3-2, repeat the weighing and recording process, until all samples are weighed, then cover the crucible lid and box lid 1-2, and fasten the safety lock 1-5. Use the handles 1-4 on the outer box 1 to carry the sample as a whole to the high-temperature pretreatment laboratory, open the outer box 1, take out the writing hole plate 3, use the transfer handles 2-2 with both hands to take out the transfer support frame 2 and the crucible, and send the whole into the muffle furnace for heating. After heating, when it drops to the temperature where it can be taken out, take out the transfer support frame 2 as a whole, confirm again that the direction mark 7 is horizontally facing forward and then put it into the outer box 1, turn on the temperature display 5 on the outer box 1 to display the real-time temperature of each crucible, and when the temperature drops to room temperature, add deionized water to dissolve the sample. Since the reaction between water and sodium hydroxide releases heat, the temperature of the solution increases, which affects the pH adjustment in the next step. Therefore, after the sample is completely dissolved, the timing of adjusting the pH needs to be determined based on the real-time temperature of the temperature display 5. After the pH adjustment of the sample is completed, it can be transferred and fixed in volume. At this time, the sample information on the writing hole plate 3 can be copied to the subsequent container and analysis record.
[0053] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.
[0054] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.
[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
