Description

Technical Field

[0001] This utility model relates to a ceramic homogenant, specifically a ceramic homogenant structure for chromatographic equipment, and belongs to the field of ceramic homogenant technology. Background Technology

[0002] Ceramic homogenizers are auxiliary components used in sample pretreatment in chromatographic equipment, rather than being the core structure of the equipment. Made of special ceramic materials, they possess excellent chemical stability, remaining stable in various chemical reagents and complex sample matrices, and are not prone to chemical reactions. This ensures that they will not contaminate the sample or interfere with the analytical results during use. Ceramic homogenizers are primarily used in the QuEChERS sample preparation method. After the sample and extractant are added to the extraction tube, the ceramic homogenizer moves rapidly within the tube through shaking or vortexing, stirring and dispersing the sample. This breaks down sample particles and disperses them into the extractant, allowing the target compound to contact the extractant more fully, thereby improving extraction efficiency.

[0003] Existing ceramic homogenants suffer from significant compatibility issues, with their fixed-size design making it difficult to meet diverse experimental needs in practical applications. Since extraction tubes of different specifications vary significantly in volume, inner diameter, and length, fixed-size ceramic homogenants cannot be adjusted for compatibility, necessitating replacement with homogenants of the appropriate size, thus increasing experimental costs. Therefore, this paper proposes a ceramic homogenant structure for chromatographic equipment. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] Please see Figures 1-5 The present invention provides a technical solution: a ceramic homogenizer structure for a chromatography device, including an inner ceramic homogenizer 31, and an outer shell assembly 101 is provided on the outside of the inner ceramic homogenizer 31;

[0028] The housing assembly 101 includes an upper ceramic cover 11, an upper limit post 13, an upper limit boss 14, a lower ceramic cover 16, a lower limit post 17, a lower limit boss 18, a retainer 19, and a pressure ring 23.

[0029] The upper ceramic cover 11 and the lower ceramic cover 16 are both fitted onto the outside of the inner ceramic homogeneous proton 31, and the upper ceramic cover 11 and the lower ceramic cover 16 are threaded together. The upper ceramic cover 11 and the lower ceramic cover 16, which are threaded together, can form an integral load-bearing frame.

[0030] Sealing gaskets 15 are bonded to the bottom of the upper ceramic cover 11 and the top of the lower ceramic cover 16. The sealing gaskets 15 ensure the airtightness of the outer shell assembly 101 and prevent external contaminants from entering. At the same time, the elasticity of the sealing gaskets 15 can enhance the shock resistance after the upper ceramic cover 11 and the lower ceramic cover 16 are connected, and the threads will not loosen.

[0031] Two limiting grooves 32 are symmetrically opened on the upper and lower surfaces of the inner ceramic homogeneous proton 31. An upper limiting post 13 is integrally provided on the inner top wall of the upper ceramic cover 11, and a lower limiting post 17 is integrally provided on the inner bottom wall of the lower ceramic cover 16. Contact pads 12 are fixedly connected to the adjacent ends of the upper limiting post 13 and the lower limiting post 17. The upper limiting post 13 and the lower limiting post 17 are both inserted into the inside of the limiting groove 32, and are both in contact with the inner wall of the limiting groove 32 through the contact pads 12. Thus, the upper limiting post 13, the lower limiting post 17 and the contact pads 12 can restrict any movement and rotation of the inner ceramic homogeneous proton 31 in the radial plane, ensuring the accuracy of the position of the inner ceramic homogeneous proton 31.

[0032] The lower surface of the retainer 19 is attached to the upper surface of the lower limiting boss 18, the upper surface of the retainer 19 is attached to the lower surface of the pressure ring 23, the pressure ring 23 is slidably connected to the inner wall of the lower ceramic cover 16, and the upper surface of the pressure ring 23 is attached to the lower surface of the upper limiting boss 14. The pressure ring 23 is used to limit the position of the retainer 19 and prevent the retainer 19 from axially displacing.

[0033] The inner wall of the upper ceramic cover 11 is integrally provided with an upper limit boss 14, and the inner wall of the lower ceramic cover 16 is integrally provided with a lower limit boss 18. The retainer 19 and the pressure ring 23 are both sleeved on the outside of the inner ceramic homogenizer 31. When the upper ceramic cover 11 and the lower ceramic cover 16 are connected, the axial force generated by the thread rotation is transmitted sequentially through the upper limit boss 14-pressure ring 23-retainer 19-lower limit boss 18, and finally the force is applied to the retainer 19, thereby keeping the retainer 19 in a fixed position.

[0034] The cage 19 can securely limit the position of the inner ceramic homogenant 31, preventing the inner ceramic homogenant 31 from moving axially.

[0035] In this embodiment, specifically: buffer pads 22 are adhered to both the inner and outer walls of the retainer 19. The retainer 19 is attached to the outer wall of the inner ceramic homogenizer 31 through the buffer pads 22, and is also attached to the inner wall of the lower ceramic cover 16 through the buffer pads 22. This allows the retainer 19 to flexibly fit with the inner ceramic homogenizer 31 and the lower ceramic cover 16, reducing the risk of ceramic breakage due to installation stress or working vibration.

[0036] Regarding the working principle or structural principle, during the pretreatment of samples in the chromatographic equipment, depending on the size of the extraction tube, it is decided whether to install the outer shell assembly 101 on the outside of the inner ceramic homogenizer 31. When it is necessary to install the outer shell assembly 101:

[0037] First, the retainer 19 is fitted onto the outside of the inner ceramic homogenizer 31. Then, the inner ceramic homogenizer 31 is placed inside the lower ceramic cover 16, ensuring that the bottom limiting groove 32 aligns with the lower limiting post 17. Next, the retainer 19 is pushed to fit against the lower limiting boss 18. Then, the pressure ring 23 is fitted onto the outside of the inner ceramic homogenizer 31 and fits against the retainer 19. Next, the upper ceramic cover 11 is aligned with the lower ceramic cover 16 and rotated to achieve a threaded connection. At this time, the upper limiting post 13 is inserted into the upper limiting groove 32, and the upper limiting boss 14 presses the retainer 19 through the pressure ring 23, thus completing the assembly of the large-size ceramic homogenizer, which can then be placed into the extraction tube for use.

[0038] When it is necessary to disassemble the outer casing assembly 101, rotate the upper ceramic cover 11 and the lower ceramic cover 16 in the opposite direction to separate them, then take out the inner ceramic homogenizer 31, and then remove the pressure ring 23 and the retainer 19 in sequence. At this time, a small-sized inner ceramic homogenizer 31 can be used.

[0039] Compared with the prior art, this utility model can increase the size of the ceramic homogenizer by installing a detachable outer shell assembly 101 on the outside of the inner ceramic homogenizer 31, thereby achieving size adjustment and adapting to extraction tubes of different sizes. In addition, by means of structures such as limiting posts, limiting bosses and retainers 19, the position of the inner ceramic homogenizer 31 can be effectively limited, significantly improving the stability of the structure.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
