[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Embodiment 1:

[0028] Reference Figure 1-6A jacketed circulation funnel comprises a funnel 1, on which a liquid outlet 104 is arranged, and further comprises: a mounting plate 2, fixedly connected in the funnel 1; a placement groove, arranged on the funnel 1, in which a limiting ring 4 is placed; a hollow ring 3, rotatably connected to the mounting plate 2, the hollow ring 3 being an annular plate with filter holes arranged at equal intervals; a placement groove 201, respectively arranged on the mounting plate 2 and the limiting ring 4, the placement groove 201 being used to place filter paper, the placement groove 201 being provided with an overlapping portion 202, the overlapping portion 202 being used for overlapping two ends of the filter paper, a rotating handle 301 being fixedly connected to the hollow ring 3, and the rotating handle 301 being used for rotating the hollow ring 3.

[0029] When the device is in use, first place the filter paper on the mounting groove 201 of the mounting plate 2, and place the two ends of the filter paper at the overlapping portion 202. It should be noted that the thickness of the filter paper should be close to or slightly greater than the thickness of the mounting groove 201. Then the hollow plate 3 can be placed on the mounting plate 2, and finally the limit ring 4 is covered. The mounting groove 201 on the limit ring 4 is used to limit the upper end of the filter paper to prevent the filter paper from moving. Then the drug samples to be filtered can be poured into the hollow ring 3 in the funnel 1. At this time, these samples will pass through the filter paper and then in the filter. The filtered liquid will be filtered under the action of the filter paper, and the filtered liquid will be discharged through the liquid outlet 104. In order to facilitate the rapid discharge of the sample and avoid the accumulation of residues in the fixed position of the filter paper, the hollow ring 3 can be rotated at this time to adjust the position of the filter hole. At this time, the adjusted filter hole can filter the sample more quickly. At the same time, most of the residues previously remaining on the filter paper will be separated from the filter paper under the impact of the sample flow, and then fall on the mounting plate 2. The remaining residues will also gradually loosen. When the subsequent residues are blocked on the filter paper again, it can be rotated again until the filtration is completed.

[0030] After the filtration is completed, the limiting ring 4 can be taken out, the filter paper can be taken out, and the residue remaining on the mounting plate 2 can be dumped out. After the cleaning is completed, it can be dried for the next use.

[0031] Embodiment 2:

[0032] Reference Figure 1-5 , a jacketed circulation funnel, which is basically the same as Example 1, and further: a cavity 101 is set in the funnel 1, and an interface 102 and an interface 2 103 are connected to the funnel 1, and the interface 102 and the interface 2 103 are communicated with the cavity 101.

[0033] When in use, some samples need to be filtered at a suitable temperature. At this time, liquid of suitable temperature can be injected through interface 102, and the circulating heating machine can be operated to heat the funnel 1 until the temperature inside the funnel 1 reaches a suitable range. At the same time, excess liquid will be discharged through interface 2 103 and re-enter the circulating heating machine. In this way, the heating function of the jacketed circulating funnel can be realized, and the purpose of thermal insulation filtration can be achieved through medium circulation.

[0034] Embodiment 3:

[0035] Reference Figure 1-3 , a jacketed circulation funnel, which is basically the same as Example 1, and further: the inside of the funnel 1 is coated with a non-stick coating, and the inside of the cavity 101 is coated with a thermal insulation coating.

[0036] The non-stick coating in the funnel 1 needs to be selected according to the sample situation. If it is non-corrosive, a conventional fluorocarbon coating can be used. If it needs to be corrosion-resistant, a corrosion-resistant coating can be used. The specific choice needs to be made according to the use requirements. The non-stick coating is easy to clean and can save water resources.

[0037] At the same time, the thermal insulation coating is suitable for samples that require constant temperature filtration. The jacket circulation and thermal insulation coating can be used to maintain a constant temperature to avoid material deterioration. During long-term filtration operations, the heating equipment can be turned off to save energy and protect the environment.

[0038] The utility model can continuously adjust the filter holes on the hollow ring 3 through the rotatable hollow ring 3 when in use, and can effectively avoid the filter holes being blocked by residues on the filter paper by continuously changing the positions of the filter holes, thereby facilitating the filtering of samples.

[0039] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
