[0028] The utility model provides a multifunctional separating funnel stand for chemical analysis.

[0029] Reference Figure 1 In one embodiment of the utility model, the separating funnel stand includes a support 10, a supporting assembly 20 and a driving assembly 30; the supporting assembly 20 is arranged on the support 10, and the supporting assembly 20 at least includes a first supporting bracket 21 and a second supporting bracket 22 arranged at intervals along the height direction of the support 10, and the first supporting bracket 21 and the second supporting bracket 22 are both provided with a plurality of supporting positions 201 for supporting the separating funnel 100; the driving assembly 30 is arranged on the support 10 and is drivingly connected to the first supporting bracket 21 and / or the second supporting bracket 22, so as to drive the first supporting bracket 21 and / or the second supporting bracket 22 to move along the height direction of the support 10.

[0030] In this embodiment, the support member 10 may preferably be a rod-shaped structure to save materials and facilitate the movement of the supporting member. Of course, the support member 10 may also adopt a more complex structure, which is not limited here. The bottom of the support member 10 may be provided with a base 11 or a bottom plate made of metal or plastic or the like, so as to facilitate placing the entire separating funnel stand on a workbench and ensure the stability of the support.

[0031] The supporting assembly 20 may include two or more layers of supporting frames to simultaneously place multiple separating funnels 100 to meet the use requirements of separating funnels 100 of more specifications. In this embodiment, the first supporting frame 21 and the second supporting frame 22 are both provided with a plurality of through holes spaced apart along the length direction thereof to form a plurality of supporting positions 201.

[0032] The driving component 30 can be a motor, a cylinder or an oil cylinder, etc., preferably a stepping motor, but it is not limited here.

[0033] It can be understood that the utility model drives the support frame to move in the height direction by setting a driving assembly 30, thereby realizing height adjustment of the supporting assembly 20 and the separating funnel 100 placed thereon, which can meet the requirements of separating funnels 100 of different capacities or sizes and is more convenient to use.

[0034] In addition, the existing separating funnel racks are mostly single-layer designs. When there are many experimental samples or multiple separation steps are required, it is inconvenient to use and the placement is chaotic, which can easily lead to the misplacement of experimental samples and errors in test results. The utility model effectively solves the problems of the existing technology by using at least two layers of supporting racks, and greatly ensures the accuracy of chemical analysis test results.

[0035] To further improve the extraction efficiency, refer to Figure 1 In one embodiment, the separating funnel rack may further include a test tube rack 40, which is disposed on the support member 10 and below the supporting assembly 20. The test tube rack 40 is provided with a plurality of placement slots 401 for placing test tubes, and the placement slots 401 correspond one-to-one to the supporting positions 201.

[0036] In one embodiment, if Figure 1 As shown, the second support bracket 22 can be installed on the support member 10 through a reciprocating screw 50, the driving assembly 30 is a motor, and the reciprocating screw 50 is connected to the motor.

[0037] On the one hand, the driving and transmission mechanism structure adopted in this embodiment is relatively simple, which is conducive to reducing the manufacturing cost of the separating funnel stand; on the other hand, by adopting a stepper motor, more precise automatic control of the support frame height adjustment can be achieved, further improving the convenience of use.

[0038] To further improve the convenience of use, refer to Figure 1 In one embodiment, the first support bracket 21 and / or the second support bracket 22 are rotatably disposed on the support member 10, and the rotation range can be 360°.

[0039] It should be noted that the support bracket of this embodiment can be driven manually or by automatically controlling its movement by setting a driving mechanism, which is not specifically limited here.

[0040] In the prior art, the separating funnel stand is not equipped with a dosing device, and mainly uses a measuring cylinder and a pipette for multiple aspiration and transfer. However, most extraction experiments require the addition of large volumes of chemical reagents (more organic solvents). The traditional method of transferring solvents results in large errors, and the reagent aspiration and transfer operations are more cumbersome.

[0041] In this regard, the utility model also makes relevant improvements to the separating funnel stand:

[0042] Based on the above embodiments, Figure 1 As shown, the separating funnel stand is also provided with a reagent bottle rack 60 for placing the reagent bottle 200 . The reagent bottle rack 60 is arranged on the support member 10 and is located above the supporting assembly 20 .

[0043] In order to improve the reagent transfer efficiency and further improve the extraction efficiency, in this embodiment, reference Figure 1 The separating funnel stand may further include a bottle mouth liquid dispenser 70 and a conduit 71 connected to the bottle mouth liquid dispenser 70. The bottle mouth liquid dispenser 70 is suitable for being fixed to the bottle mouth of the reagent bottle 200. The bottle mouth liquid dispenser 70 is used to extract the reagent in the reagent bottle 200 and transport it to the separating funnel 100 placed on the supporting assembly 20 through the conduit 71. Among them, the liquid outlet of the conduit 71 should be arranged corresponding to the upper inlet of the separating funnel 100, so that the medicine flows into the separating funnel 100. The number of branches of the conduit 71 can be the same as the number of supporting positions 201 of the upper supporting frame, so as to transport the reagent one-to-one. The number of branches of the conduit 71 is not limited here.

[0044] In this embodiment, the catheter 71 may preferably be an eagle-beak catheter or a flexible hose, etc., which is not limited here.

[0045] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
