[0002] Solid-liquid separation technology is a key stage in the drug synthesis process, which has a decisive impact on improving the purity of drug products, ensuring the quality of drugs and guaranteeing their safety. It mainly includes various operation methods such as filtration, sedimentation and centrifugation.

[0003] In the prior art, the filtration operation is mainly used to process solid particles with larger particle sizes. Such particles can be easily separated by physical interception due to their large sizes; in the field of drug synthesis, the filtration operation is widely used to remove solid impurities that are insoluble in solvents; traditional filtration operations often use a funnel, filter paper and a glass rod in combination to carry out refined solid-liquid separation operations; however, this method has certain limitations. Especially when the capacity of the funnel is limited, stirring with a glass rod may cause the residual solid substances on the filter paper to be carried out of the funnel, resulting in the splashing of materials and affecting the cleanliness of the workbench. Therefore, this application provides a splash-proof filtering auxiliary device. Summary of the Utility Model

[0004] In order to solve the above deficiencies in the prior art, the purpose of the utility model is to provide a splash-proof filtering auxiliary device, which can improve the utilization rate of the internal capacity of the funnel, and on this basis, reduce the need for stirring with a glass rod, has a high degree of convenience in use, and does not require secondary cleaning of the stirring rod.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A splash-proof filtering auxiliary device is provided, which includes a filtering funnel, a base and an oscillating seat. A reaction container is placed on the upper side of the top of the base. A portal frame is fixedly installed on the base. The filtering funnel is placed in the portal frame. The oscillating seat is slidably installed on the portal frame. Ring-shaped supports Ⅰ and Ⅱ that can be attached to the outer side wall of the conical structure of the filtering funnel are respectively arranged on the portal frame and the oscillating seat.

[0007] Furthermore, a leakage hole is provided at the bottom of the filtering funnel. The filtering funnel is located above the reaction container, and filter paper is placed in the filtering funnel.

[0008] Furthermore, a ring rib is integrally formed on the outer side of the bottom of the filtering funnel. A U-shaped handle is installed on the ring rib. The upper side surface of the U-shaped handle can be abutted against the lower side surface of the ring-shaped support Ⅰ.

[0009] Furthermore, the U-shaped handle is inserted and slidably connected to the ring rib.

[0010] Furthermore, the outer diameter of the annular rib is smaller than the inner diameter of the first annular support.

[0011] Furthermore, at least two T-shaped columns are fixedly installed at the bottom of the oscillation seat, and the T-shaped columns are slidably connected to the gantry.

[0012] Furthermore, a plurality of leakage holes are provided, and the plurality of leakage holes are arranged at equal intervals at the bottom of the filtering funnel.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. For the anti-splash filtering auxiliary device according to the example of the present utility model, a solid-liquid mixture is added into the filtering funnel, and then the oscillation seat is controlled to perform vertical reciprocating lifting. During this process, the outer side wall of the filtering funnel is continuously separated from and then re-abutted against the first annular support, applying an oscillating force to the solid-liquid mixture therein; since there is no need to reserve space for stirring the solid residue, more solid-liquid mixture can be added into the filtering funnel, thereby greatly improving the utilization rate of the internal capacity of the funnel.

For the anti-splash filtering auxiliary device according to the example of the present utility model, the U-shaped handle is inserted on the annular rib, and the upper side surface of the U-shaped handle is abutted against the lower side surface of the first annular support to limit the maximum lifting height of the filtering funnel and prevent the filtering funnel from slipping off. At the same time, the intermittent abutment between the U-shaped handle and the first annular support is utilized to enhance the oscillating treatment effect on the solid-liquid mixture inside the filtering funnel.

[0016] 3. For the anti-splash filtering auxiliary device according to the example of the present utility model, the outer diameter of the annular rib is smaller than the inner diameter of the first annular support, enabling the filtering funnel to be smoothly disassembled from the first annular support and the second annular support, and facilitating the cleaning and maintenance of the filtering funnel.

[0028] Embodiment 1:

[0029] As Figure 1-2As shown in the figure, this embodiment provides a splash-proof filtering aid, which includes a filtering funnel 11, a base 21, and an oscillating seat 31. A reaction vessel 1 is placed on the upper side of the top of the base 21. A portal frame is fixedly installed on the base 21. The filtering funnel 11 is placed inside the portal frame. The oscillating seat 31 is slidably installed on the portal frame. A handle 33 is provided on the side of the oscillating seat 31. An annular support I 22 and an annular support II 32 are respectively provided on the portal frame and the oscillating seat 31, which can be attached to the outer side wall of the conical structure of the filtering funnel 11.

[0030] Wherein, at least two T-shaped columns are fixedly installed at the bottom of the oscillating seat 31. The T-shaped columns are slidably connected to the portal frame, which not only limits the maximum rising height of the oscillating seat 31 but also improves the sliding stability of the oscillating seat 31.

[0031] As Figure 3 shown, a leakage hole 111 is provided at the bottom of the filtering funnel 11. The filtering funnel 11 is located above the reaction vessel 1, and a filter paper is placed inside the filtering funnel 11.

[0032] When using the splash-proof filtering aid of this application:

[0033] Place the reaction vessel 1 on the base 21 and add a solid-liquid mixture into the filtering funnel 11. Then, hold the handle 33 and control the oscillating seat 31 to perform vertical reciprocating lifting and lowering. During this process, the outer side wall of the filtering funnel 11 is continuously separated from and then re-abutted against the annular support I 22, applying an oscillating force to the solid-liquid mixture inside it. While ensuring the filtering efficiency, it reduces the need for stirring the glass rod, so there is no need to clean the stirring rod twice, increasing the operation convenience;

[0034] Since there is no need to reserve space for turning over solid residues, more solid-liquid mixture can be added into the filtering funnel 11, thus greatly improving the utilization rate of the internal capacity of the funnel.

[0035] To prevent the filtering funnel 11 from slipping off the device during vertical movement, as Figure 2-3 shown, a ring rib 12 is integrally formed on the outer side of the bottom of the filtering funnel 11, and a U-shaped handle 13 is inserted and installed on the ring rib 12, so that the upper side of the U-shaped handle 13 can abut against the lower side of the annular support I 22. By using the upper side of the U-shaped handle 13 to abut against the lower side of the annular support I 22, the maximum rising height of the filtering funnel 11 is restricted to prevent the filtering funnel 11 from slipping off;

[0036] At the same time, by using the intermittent abutment of the U-shaped handle 13 and the annular support I 22, the oscillating treatment effect on the solid-liquid mixture inside the filtering funnel 11 is increased.

[0037] As Figure 1-2As shown, the outer diameter of the corrugated ring 12 is smaller than the inner diameter of the annular support I 22, so that the filter funnel 11 can be smoothly disassembled on the annular support I 22 and the annular support II 32, facilitating the cleaning and maintenance of the filter funnel 11.

[0038] Embodiment 2:

[0039] The features identical to those in Embodiment 1 will not be described in detail. The difference between this embodiment and Embodiment 1 lies in that, as Figure 3 shown, in this embodiment, a plurality of leakage holes 111 are provided, and the plurality of leakage holes 111 are arranged at equal intervals at the bottom of the filter funnel 11; by reducing the diameter of the leakage holes 111 and increasing the number of the leakage holes 111, when filtering solid materials with a relatively large particle size, the leakage holes 111 can be directly used to intercept the solid materials, reducing the demand for filter paper.

[0040] The above description is only the preferred embodiment of the present application and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features with similar functions disclosed in the present application.

[0041] Except for the technical features described in the specification, the rest of the technical features are well-known to those skilled in the art. To highlight the innovative features of the present utility model, the rest of the technical features will not be described in detail here.
