Description

Technical Field

[0001] This utility model relates to the field of sample testing and experimental technology, and specifically provides a crucible assembly. Background Technology

[0002] Due to their high-temperature resistance, structural stability, and low reactivity with samples, crucibles have become the preferred containers in sample testing experiments such as physical adsorption, chemical adsorption, and thermogravimetric analysis, playing an indispensable role in materials research and chemical analysis.

[0003] During sample testing experiments, the reactant gas can only diffuse from the top to the vicinity of the sample inside the crucible, limiting the diffusion rate. Furthermore, the reactant gas can only react with the sample surface, resulting in a slow reaction rate. To improve the reaction rate, existing technologies incorporate vents in the crucible to increase the contact area between the gas and the sample. However, crucibles with vents cannot be used when the sample is a liquid or powder sample.

[0004] Accordingly, there is a need in the art for a new crucible assembly to address the aforementioned problems. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that the crucible in the prior art limits the reaction rate of liquid or powder samples during experiments.

[0006] This utility model provides a crucible assembly, which includes: a plurality of crucible bodies, the top of each crucible body having a receiving space for holding a sample, the plurality of crucible bodies being stacked vertically; and a spacer disposed between two adjacent crucible bodies to form a gap between the two adjacent crucible bodies.

[0007] By employing the above technical solution, multiple crucible bodies are vertically stacked, with each crucible body having a space at its top to hold the sample. This allows the sample to be divided into multiple portions and placed on each crucible body, effectively increasing the contact area between the sample and the gas. Adjacent crucible bodies are separated by spacers, creating gaps that allow the gas to flow through to the top of the non-top crucible body and contact the sample. This ensures that each sample can fully contact the reactant gas, effectively improving the reaction rate. Furthermore, no vent holes are required, making it suitable for reaction testing experiments involving various samples, including liquid and powder samples. Thus, it achieves the ability to hold multiple samples, such as liquid and powder samples, while also increasing the reaction rate.

[0008] In a specific embodiment of the crucible assembly described above, the crucible assembly further includes a connecting rod that passes vertically through the plurality of crucible bodies and is connected to the plurality of crucible bodies.

[0009] With the above technical solution, multiple crucible bodies are vertically connected into a whole by connecting rods, which makes it easy to pick up and put down, and also easy to connect with sample experimental equipment.

[0010] In a specific embodiment of the crucible assembly described above, the crucible assembly further includes a base plate, which is disposed below the plurality of crucible bodies, and the bottom of the connecting rod is fixedly connected to the base plate.

[0011] With the above technical solution, the bottom of the connecting rod is fixedly connected to the base plate, and multiple crucible bodies are sleeved on the connecting rod. The multiple crucible bodies are supported by the base plate and connected into a whole by the connecting rod. This makes it convenient to pick up and put down the crucible assembly as a whole, as well as to pick up and put down individual crucible bodies. Moreover, the structures of multiple crucible bodies can be completely identical, which improves versatility and saves processing costs.

[0012] In a specific embodiment of the crucible assembly described above, the spacer is sleeved outside the connecting rod.

[0013] When the above technical solution is adopted, the spacer and the crucible body are connected as a whole by a connecting rod.

[0014] In a specific embodiment of the crucible assembly described above, a hook is provided at the top of the connecting rod.

[0015] With the above technical solution, the crucible assembly can be conveniently hung in the corresponding position of the sample experimental equipment via hooks.

[0016] In a specific embodiment of the above-described crucible assembly, the spacer is fixedly connected to the top of the crucible body.

[0017] By adopting the above technical solution, the spacer is directly fixed to the top of the crucible body, and the crucible bodies are then stacked vertically, which facilitates installation.

[0018] In a specific embodiment of the crucible assembly described above, the spacer is fixedly connected to the top of each crucible body, and an annular protrusion is provided on the top edge of the crucible body. The annular protrusion, the spacer, and the bottom wall of the crucible body enclose the receiving space, and the top surface height of the spacer is higher than the top surface height of the annular protrusion.

[0019] With the above technical solution, each crucible body is surrounded by an annular protrusion, a spacer, and the bottom wall of the crucible body to form a receiving space, which can hold a variety of samples. The annular protrusion can prevent the samples from spilling out of the receiving space, and the top surface of the spacer is higher than the top surface of the annular protrusion to ensure that a gap is formed between two adjacent crucible bodies.

[0020] In a specific embodiment of the crucible assembly described above, the spacer is located at the center of the crucible body.

[0021] By adopting the above technical solution, the stability between the crucible bodies can be improved, and instability caused by offset can be avoided.

[0022] In a specific embodiment of the above-described crucible assembly, the spacer is integrally formed with the crucible body.

[0023] By adopting the above technical solution, the installation process can be simplified and the stability and reliability of the connection between the crucible body and the spacer can be improved.

[0024] In a specific embodiment of the above-mentioned crucible assembly, the material of the crucible body is one of stainless steel, aluminum, titanium, ceramic, glass, quartz, and graphite.

[0025] By adopting the above technical solution, the crucible body can be made to have the characteristics of high temperature resistance, structural stability and almost no reaction with the sample, so as to hold the sample for analysis experiments and minimize the impact on the analysis experiments.

[0026] Compared with the prior art, the beneficial effects of the crucible assembly provided by this utility model are as follows: by vertically stacking multiple crucible bodies, each crucible body has a receiving space at its top to hold the sample, allowing the sample to be divided into multiple portions and placed on multiple crucible bodies respectively, which can effectively increase the contact area between the sample and the gas. Adjacent crucible bodies are separated by spacers to form gaps, allowing the gas to flow through the gaps to the top of the non-top crucible body and contact the sample, ensuring that each sample can fully contact the reaction gas, effectively improving the reaction rate of the sample. Moreover, there is no need to set up vent holes, so it can be used for reaction testing experiments of various samples, including liquid samples and powder samples, thereby achieving the ability to hold various samples such as liquid samples and powder samples while improving the reaction rate of the sample.

[0032] Some embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

Therefore, they should not be construed as limitations on this utility model. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0034] Furthermore, it should be noted that in the description of this utility model, ordinal numbers such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Based on the background art, existing crucibles in the prior art limit the reaction rate of liquid or powder samples during experiments. The aim is to address this issue by vertically stacking multiple crucible bodies, each with a top space to hold the sample. This allows the sample to be divided into multiple portions and placed on each crucible body, effectively increasing the contact area between the sample and the gas. Adjacent crucible bodies are separated by spacers, creating gaps that allow gas to flow through to the top of the non-top crucible body and contact the sample. This ensures that each sample has sufficient contact with the reacting gas, effectively improving the reaction rate. Furthermore, no vent holes are required, making it suitable for reaction testing experiments involving various samples, including liquids and powders. Thus, it achieves the goal of accommodating multiple samples while simultaneously increasing the reaction rate.

[0036] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the crucible assembly of this utility model. Figure 2 This is a cross-sectional view of the crucible assembly of this utility model. (See attached image.) Figure 1 and Figure 2 As shown, the crucible assembly of this utility model includes multiple crucible bodies 1 and spacers 2. A receiving space 11 is formed on the top of each crucible body 1 for holding samples. Multiple crucible bodies 1 are stacked vertically. Spacers 2 are positioned between adjacent crucible bodies 1 to create gaps between them. By vertically stacking multiple crucible bodies 1, each crucible body 1 has a receiving space 11 on its top to hold samples. This allows the samples to be divided into multiple portions and placed on the multiple crucible bodies 1, effectively increasing the contact area between the samples and the gas. The spacers 2 separate adjacent crucible bodies 1, creating gaps that allow gas to flow through to the top of the non-top crucible body 1 and contact the samples. This ensures that each sample can fully contact the reacting gas, effectively improving the reaction rate. Furthermore, since there is no need for venting holes, this assembly is suitable for reaction testing experiments involving various samples, including liquid and powder samples. Thus, it achieves the ability to hold multiple samples, such as liquid and powder samples, while also improving the reaction rate.

[0037] It should be noted that the number of crucible bodies 1 can be two, three or more, and no specific limitation is made here. Those skilled in the art can adjust it as needed.

[0038] Continue reading Figure 1 and Figure 2In one possible implementation, the crucible assembly further includes a connecting rod 3 and a base plate 4. The base plate 4 is located below multiple crucible bodies 1. The connecting rod 3 passes vertically through the multiple crucible bodies 1, and its bottom is fixedly connected to the base plate 4. A spacer 2 is sleeved on the outside of the connecting rod 3. With the bottom of the connecting rod 3 fixedly connected to the base plate 4, the multiple crucible bodies 1 are sleeved on the connecting rod 3, supported by the base plate 4, and connected into a whole by the connecting rod 3. This facilitates the overall placement and removal of the crucible assembly, as well as the placement and removal of individual crucible bodies 1. Furthermore, the structures of the multiple crucible bodies 1 can be identical, improving versatility and saving processing costs.

[0039] Specifically, the bottom of the connecting rod 3 is provided with an external thread, and the base plate 4 is provided with a threaded hole. The connecting rod 3 is threadedly connected to the threaded hole through the external thread. In addition, the bottom of the connecting rod 3 may also be provided with a buckle, and the base plate 4 is provided with a slot. The connecting rod 3 and the base plate 4 are fixedly connected by the buckle and the slot. The fixed connection between the connecting rod 3 and the base plate 4 can also be achieved by other detachable connection methods or non-detachable connection methods such as welding or bonding, as long as the bottom of the connecting rod 3 and the base plate 4 can be fixedly connected. Those skilled in the art can make adjustments as needed.

[0040] Those skilled in the art will understand that, although the above combination Figure 1 and Figure 2 The description indicates that the crucible assembly also includes a connecting rod 3 and a base plate 4. The bottom of the connecting rod 3 is fixedly connected to the base plate 4, but this is not limiting. The crucible assembly may also exclude the base plate 4, and the connecting rod 3 may be directly fixedly connected to the bottommost crucible body 1. The connecting rod 3 may also be fixedly connected to multiple crucible bodies 1. In addition, the crucible assembly may also exclude the connecting rod 3 and the base plate 4. A connecting block is provided at the top of the crucible body 1, and a connecting hole is provided at the bottom of the crucible body 1. The connecting block and the connecting hole are connected to two adjacent crucible bodies 1 by snap-fit, threaded connection, welding or bonding. As long as multiple crucible bodies 1 can be connected to one unit, it is acceptable. Those skilled in the art can make adjustments as needed, without departing from the principle of this utility model, and all are within the protection scope of this utility model.

[0041] Continue reading Figure 1 and Figure 2 As one possible implementation, the top of the connecting rod 3 is provided with a hook 5. The crucible assembly can be conveniently hung on the corresponding position of the sample experimental equipment via the hook 5. The sample experimental equipment can be a magnetic levitation balance or a vapor adsorption apparatus. The crucible assembly can be hung on the weighing hook of the magnetic levitation balance or on the sample hook 5 of the vapor adsorption apparatus via the hook 5. It should be noted that the hook 5 and the connecting rod 3 can be integrally formed, or they can be set as two separate structures, fixedly connected by threaded connection, welding, bonding, or other methods.

[0042] Continue reading Figure 1 and Figure 2 In one possible implementation, a spacer 2 is fixedly connected to the top of each crucible body 1, and an annular protrusion 12 is provided on the top edge of the crucible body 1. The annular protrusion 12, the spacer 2, and the bottom wall of the crucible body 1 form a receiving space 11. The top surface of the spacer 2 is higher than the top surface of the annular protrusion 12. Each crucible body 1 has a receiving space 11 formed by the annular protrusion 12, the spacer 2, and the bottom wall of the crucible body 1, which can hold multiple samples. The annular protrusion 12 can prevent the samples from spilling out of the receiving space 11, and the top surface of the spacer 2 is higher than the top surface of the annular protrusion 12 to ensure that a gap is formed between two adjacent crucible bodies 1.

[0043] Those skilled in the art will understand that, although the above combination Figure 1 and Figure 2 The description describes a spacer 2 fixedly connected to the top of the crucible body 1. However, this is not limiting; the spacer 2 can also be a separate sleeve, fitted over the connecting rod 3 and positioned between two adjacent crucible bodies 1. There is no direct fixed connection between the spacer 2 and the crucible body 1. Correspondingly, each crucible body 1 has a boss at its top center, and the spacer 2 contacts the boss. The boss, the annular protrusion 12, and the bottom wall of the crucible body 1 form a receiving space 11. Furthermore, the spacer 2 can also be integrally formed with the crucible body 1 to simplify the installation process and improve the stability and reliability of the connection between the crucible body 1 and the spacer 2. All these adjustments do not depart from the principle of this utility model, and those skilled in the art can make adjustments as needed, all within the protection scope of this utility model.

[0044] Continue reading Figure 1 and Figure 2 As one possible implementation, the spacer 2 is located at the center of the crucible body 1, which can improve the stability between the crucible bodies 1 and avoid instability caused by offset. Furthermore, when a connecting rod 3 is provided, a through hole is opened at the center of both the spacer 2 and the crucible body 1, and the connecting rod 3 passes through the through hole to vertically connect the spacer 2 and the crucible body 1.

[0045] Optionally, the material of the crucible body 1 can be one of stainless steel, aluminum, titanium, ceramic, glass, quartz, or graphite, which enables the crucible body 1 to have the characteristics of high temperature resistance, structural stability, and almost no reaction with the sample, so as to hold the sample for analysis experiments and minimize the impact on the analysis experiments.

[0046] It should be noted that the above embodiments are only used to illustrate the principle of this utility model and are not intended to limit the scope of protection of this utility model. Without departing from the principle of this utility model, those skilled in the art can adjust the above embodiments so that this utility model can be applied to more specific application scenarios.

[0047] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
