Description

Technical Field

[0001] This utility model belongs to the field of material purification equipment, and in particular relates to a pressure permeation device for material purification. Background Technology

[0002] In existing technologies, the purification of some materials requires continuously dissolving impurities in the material with solvent. The solvent used to dissolve the impurities is then poured out, and the impurities are continuously dissolved by adding more solvent, thereby achieving the purpose of material purification. However, existing purification equipment requires manual pouring out of the solvent used to dissolve the impurities. On the one hand, the pouring out may not be thorough, leaving residual solvent containing impurities. On the other hand, during the pouring process, the purified sample may be lost along with the impurity solvent, resulting in a reduction in sample size, affecting accuracy, and potentially causing physical harm to the operator. Utility Model Content

[0003] The purpose of this invention is to provide a permeation purification device that aims to solve the technical problems of incomplete solvent removal and harm to operators in the prior art.

[0004] This invention is implemented as follows: the permeation purification device includes a heating plate with positioning holes for placing the purification vessel. The purification vessel includes a cup-shaped vessel wall with multiple layers of filter media at its bottom. A Teflon permeation layer is provided on the top layer of the filter media, and a leak-proof layer is provided below the Teflon permeation layer. A leakage hole is provided in the center of the leak-proof layer. The purification device also includes a pressurizing device that can be movably covered to cover the upper cup opening of the purification vessel.

[0005] A further technical solution of this utility model is: a flow guiding layer is provided between the Teflon permeation layer and the leak-proof layer, and the flow guiding layer is provided with flow guiding holes in the radial direction. The end of the flow guiding hole near the center is connected to the leakage hole; there are multiple flow guiding holes, which radiate outward in a petal shape.

[0006] A further technical solution of this utility model is: the purification equipment also includes a rubber plug mechanism for sealing the leakage hole; the rubber plug mechanism is a one-way valve structure, including a rubber plug, a support rod is provided at the bottom of the rubber plug, a base is provided at the lower end of the support rod, and a compression spring is provided between the rubber plug and the base and fitted on the support rod.

[0008] The beneficial effects of this utility model are: the solvent containing impurities is discharged by osmosis, which can ensure that the solvent is completely discharged. During the operation, the operator basically does not come into contact with the purification vessel, which can keep the operator away from chemical solvents and effectively protect the operator's health.

[0012] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0014] like Figure 1As shown, the present invention provides a permeation purification device including a heating plate 10, on which a positioning hole 11 for placing a purification vessel 20 is provided. The purification vessel 20 includes a cup-shaped vessel wall 21, the bottom of which is covered with a multi-layered filter section 22. A Teflon permeation layer 221 is provided on the top layer of the filter section 22, and a leak-proof layer 222 is provided below the Teflon permeation layer 221. A leakage hole 223 is provided in the center of the leak-proof layer 222. The purification device also includes a pressurizing device 30 that can movably cover the upper cup opening of the purification vessel 20. The technical solution of this utility model is as follows: after adding solvent and dissolving impurities, a pressurizing device 30 is sealed on the mouth of the purification vessel 20 to pressurize the purification vessel 20. The solvent containing dissolved impurities permeates out from the Teflon permeation layer 221 at the bottom and is discharged through the leakage hole 223. The Teflon permeation layer 221 is a microporous filter material with the characteristics of not leaking under normal pressure but allowing liquid to permeate under a certain pressure. This utility model utilizes this characteristic of Teflon microporous material. During the purification reaction, the Teflon permeation layer does not leak, which can ensure the normal progress of the purification process. When it is necessary to discharge the solvent, the purification vessel is pressurized to open the micropores of the Teflon permeation layer 221 and discharge the solvent.

[0015] like Figure 2 and Figure 3 As shown, a flow guiding layer 23 is provided between the Teflon permeation layer 221 and the leak-proof layer 222. This flow guiding layer 23 has radially arranged flow guiding holes 231, with the end of each flow guiding hole 231 connected to the leakage hole 223 near its center. Multiple flow guiding holes 231 radiate outwards in a petal-like pattern. The purpose of adding the flow guiding layer 23 in this design is to accelerate the solvent discharge rate and to quickly collect the solvent that has permeated from the surrounding area at the leakage hole 223 for discharge.

[0016] like Figure 2 As shown, the purification equipment also includes a rubber stopper mechanism 40 for sealing the leakage hole 223. The rubber stopper mechanism 40 is a one-way valve structure, including a rubber stopper 41, a support rod 42 at the bottom of the rubber stopper, a base 43 at the lower end of the support rod 42, and a compression spring 44 fitted onto the support rod 42 between the rubber stopper 41 and the base 43. The rubber stopper mechanism 40 in this design prevents solvent from seeping out of the Teflon permeation layer 221 during the purification process at high temperature and normal pressure, which would reduce the solvent and affect the purification effect. When the purification vessel is pressurized, the pressure pushes down the rubber stopper 41, opening the leakage hole 223. At normal pressure, the rubber stopper closes the leakage hole 223 under the action of the compression spring.

[0017] like Figure 1As shown, the pressurizing device 30 of this utility model includes a cup lid 31 for sealing the mouth of the purification vessel 20, a pressurizing pipe 32 leading to the purification vessel 20 is provided in the center of the cup lid, and further includes a pressurizing air pump 33 connected to the pressurizing pipe 32. This solution adopts air pressurization, which is convenient to use, low in cost, and has minimal impact on the purified materials.

[0018] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
