Description

Technical Field

[0001] This utility model relates to the field of sample analysis, and in particular to an integrated drying and storage device for XRD analysis of liquid samples. Background Technology

[0002] Some existing liquid samples cannot be qualitatively analyzed using XRD. If a liquid does not undergo crystal transformation, thermal decomposition, or other chemical reactions during drying at 105℃ and can be completely dried, maintaining its crystal structure after drying, then XRD analysis can be performed to obtain accurate crystal structure information. However, if the sample undergoes a crystal transformation during drying at 105℃—for example, some hydrates lose their water of crystallization at this temperature and undergo a crystal transformation—or if a thermal decomposition reaction occurs, leading to changes in the sample's chemical composition and crystal structure, then XRD analysis of the dried sample will not accurately reflect the structural information of the original sample. In such cases, direct drying followed by XRD is not suitable. Therefore, for liquids where the solute can form crystalline substances after drying, drying treatment can be used first for qualitative XRD analysis.

[0003] Traditional drying and storage equipment are independent of each other. The operation process from drying to storage to sample preparation before XRD analysis is cumbersome. The equipment is also prone to deliquescence during the transfer process, which makes it difficult to meet the testing requirements. The structure needs to be improved. Summary of the Invention

[0004] This invention addresses the aforementioned shortcomings of existing technologies by providing an integrated drying and storage design. This design simplifies and improves efficiency, reduces sample contact with humid air, significantly lowers the probability of sample deliquescence, ensures sample stability, enables rapid analysis, and enhances work efficiency and accuracy. The multi-layered sample rack design allows each layer to move vertically, meeting diverse drying and storage needs for liquid samples used in XRD analysis.

[0005] The objective of this utility model is achieved through the following technical solution:

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0024] Example 1:

[0025] An integrated drying and storage device for XRD analysis of liquid samples includes a drying chamber 01 and a storage chamber 02. The drying chamber 01 is connected to the storage chamber 02 on the outside. One side of the drying chamber 01 is connected to a first sealing surface 03 via a rotating shaft, and one side of the storage chamber 02 is connected to a second sealing surface 04 via a rotating shaft. The drying chamber 01 has a heating chamber 16 inside, and a resistance wire 17 is arranged inside the heating chamber 16. The drying chamber 01 has multiple first positioning protrusions 11, which are symmetrically arranged. A sample holder 05 is connected to the upper part of the first positioning protrusion 11, and the sample holder 05 slides on the first positioning protrusion 11. The integrated drying and storage design reduces cumbersome operation steps such as sample transfer, and the process from drying to storage to sample preparation before XRD analysis is simpler and more efficient.

[0026] Example 2:

[0027] The storage cavity 02 of this utility model has multiple second positioning protrusions 12 on the inner side. The second positioning protrusions 12 are symmetrically arranged. The upper part of the second positioning protrusion 12 is connected to the sample rack 05. The sample rack 05 slides on the second positioning protrusion 12. The adjustable design of the sample rack 05 and the sealing cover 06 can adapt to samples of different shapes and properties. The multi-layer design allows each layer of the sample rack 05 to move up and down to adapt to sample containers of different heights, meeting diverse drying and storage needs.

[0028] Example 3:

[0029] The storage cavity 02 of this utility model has two positioning protrusions 13 at the bottom, which are symmetrically arranged. The desiccant box 09 is connected to the inside of the positioning protrusions 13 and slides within the positioning protrusions 13. Multiple sealing covers 06 are connected to the upper part of the sample holder 05.

[0030] Example 4:

[0031] The lower part of the sealing cover 06 of this utility model has an annular plastic suction cup 15, and the upper part of the sample holder 05 has multiple sealing grooves 08. The sealing grooves 08 are evenly distributed in the upper part of the storage cavity 02. A sample holder 18 is provided inside the sealing groove 08. The outer side of the annular plastic suction cup 15 is connected to the sealing groove 08 and slides in the sealing groove 08. The outer side of the sealing groove 08 has an adjusting groove 10. The inner side of the adjusting groove 10 is connected to a sealing insert 07 and slides in the adjusting groove 10. Two auxiliary springs 14 are connected to the outer side of the resistance wire 17. The auxiliary springs 14 are symmetrically arranged and the outer side of the auxiliary springs 14 is connected to the adjusting groove 10 and slides in the adjusting groove 10. The upper part of the sealing insert 07 is connected to an annular plastic suction cup 15. The plastic suction cup 15 and the sealing plate 07 slide under the annular plastic suction cup 15. After drying, the sample is directly stored in the sealed storage chamber 02, which can effectively reduce humidity and reduce the chance of the sample coming into contact with humid air, greatly reducing the probability of sample deliquescence and ensuring the stability of the sample. This provides a guarantee for accurate XRD analysis. The sealing cover 06 has an annular plastic suction cup 15 at the bottom. When the sealing cover 06 is closed, it can fit tightly with the sealing groove 08 to form a sealed space, effectively isolating the external humid air and protecting the dried crystalline sample. After obtaining the crystalline substance, it can be directly stored. It is convenient to take out the sample for preparation before XRD analysis, reducing the probability of sample deliquescence, realizing rapid analysis, and improving work efficiency and the accuracy of analysis results.

[0032] Example 5:

[0033] Installation steps: First, open the first sealing surface 03 of the drying chamber 01 and place the container containing the liquid sample on the sample holder 18 on the upper part of the sample rack 05. Close the first sealing surface 03 of the drying chamber 01, set the heating to 1 sample rack 05℃, and the heating system will start working. The resistance wire 17 will heat up rapidly, gradually raising the temperature inside the drying chamber 01 to 1 sample rack 05℃. Dry the liquid sample. After drying, open the first sealing surface 03 and quickly remove the sample rack 05. Then, open the second sealing surface 04 on the front side of the storage chamber 02 and quickly place the sample rack 05 on the second positioning protrusion 12 inside the storage chamber 02. The sample rack 05 features an adjustable design. The sealing cover 06 is adaptable to samples of different shapes and properties. Its multi-layer design allows each sample rack 05 to move vertically to accommodate sample containers of varying heights, meeting diverse drying and storage needs. Simultaneously, the sealing cover 06 covers the outside of containers containing liquid samples. The annular plastic suction cup 15 at the bottom of the sealing cover 06 adheres to the sealing groove 08, creating a tight seal and protecting the dried crystalline sample from humid air. Meanwhile, the desiccant inside the desiccant box 09 also absorbs and dries the moisture in the storage chamber 02, reducing the humidity inside the storage chamber 02 and ensuring its proper functioning. 2. Internal drying further protects the dried crystalline sample from humid air. The integrated drying and storage design reduces cumbersome steps such as sample transfer. From drying to storage and sample preparation before XRD analysis, the process is simpler and more efficient. After drying, the sample is stored directly in the sealed storage chamber 02, which effectively reduces humidity and minimizes the chance of the sample coming into contact with humid air, greatly reducing the probability of sample deliquescence and ensuring sample stability. This provides a guarantee for accurate XRD analysis. The lower part of the sealing cover 06 is equipped with a ring-shaped plastic suction cup 15. When the sealing cover 06 is closed, it can fit tightly with the sealing groove 08 to form a sealed space, effectively isolating external moisture. Humid air protects the dried crystalline sample. Before XRD analysis, open the second sealing surface 04 on the front of the storage chamber 02, locate the corresponding sample, and slide the sealing insert 07 outward. The sealing insert 07 separates from the annular plastic suction cup 15 at the bottom of the sealing cover 06, allowing air to enter the sealing cover 06. This loosens the connection between the annular plastic suction cup 15 and the sealing groove 08. By pulling up the sample holder 05, the sample can be taken out for rapid sample preparation and XRD analysis can be completed immediately. After obtaining the crystalline substance, it can be directly stored. It is convenient to take out the sample for preparation before XRD analysis, reducing the probability of sample deliquescence, achieving rapid analysis, and improving work efficiency and the accuracy of analysis results.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
