Description

Technical Field

[0001] This utility model relates to the field of containers, and in particular to a purification container and purification device. Background Technology

[0002] The bacterial reverse mutation assay involves extracting and separating organic matter from surface water using macroporous resin, then treating histidine-deficient bacterial strains with the resulting material. The number of colonies grown is then used to determine whether the tested substance is a mutagen and whether it has mutagenic properties.

[0003] Because macroporous resins contain many impurities after production, they need to be purified before bacterial reverse mutation experiments. This purification involves soaking and washing the macroporous resin with organic reagents. Currently, Soxhlet extractors are mainly used for macroporous resin purification. Soxhlet extractors utilize solvent reflux and siphon principles, but the purification process requires manual monitoring of solvent level, temperature, and reflux status, making it cumbersome and unable to meet the demand for macroporous resins in large-scale surface water sample processing. Utility Model Content

[0004] The purpose of this invention is to solve the problem of cumbersome operation in the current method of purifying macroporous resins using a Soxhlet extractor. This invention provides a purification container and device that effectively simplifies the purification process for macroporous resins.

[0005] To address the aforementioned technical problems, this utility model discloses a purification container, comprising:

[0006] The bottle body includes:

[0007] A receiving cavity for holding reagents and materials to be purified;

[0008] The first opening is located at one end of the bottle body;

[0009] The second opening is located at the other end of the bottle body;

[0010] A first cover is configured to be detachably connected to the first opening, the first cover having a first air port and a second air port, the first air port and the second air port being configured to introduce gas into the receiving cavity;

[0011] A second cover is configured to be detachably connected to the first opening or the second opening, and the second cover has a third vent configured to introduce gas into or exhaust gas from the receiving cavity.

[0012] A filter element is disposed within the receiving cavity;

[0013] The purification container has a first state and a second state. In the first state, the first cover is connected to the first opening, the second cover is connected to the second opening, and the second air port is in communication with the third air port. In the second state, the second cover is connected to the second opening, and the first cover is not connected to the first opening.

[0014] Using the above technical solution, when it is necessary to purify macroporous resin, simply connect the first cap to the first opening of the bottle and the second cap to the second opening of the bottle so that the purification container is in the first state. Then, gas (such as nitrogen or other gases that do not chemically react with reagents or macroporous resin) is introduced into the containing cavity through the first gas port of the first cap, thereby allowing the macroporous resin to fully contact the reagent and improve the purification effect.

[0015] Furthermore, once purification is complete, opening the first cap allows the reagent to be discharged from the bottle's containing cavity. Because a filter is installed in the bottle, the macroporous resin is not discharged during the reagent discharge process, thus enabling the temporary storage of the macroporous resin.

[0016] According to a specific embodiment of the present invention, it further includes a third cover, which is a sealing cover and is configured to be detachably connected to the first opening or the second opening;

[0017] The purification container has a third state in which the first cap is not connected to the bottle body, the second cap is not connected to the bottle body, and the third cap is connected to the first opening.

[0018] According to a specific embodiment of the present invention, the filter sheet is provided with a plurality of small holes, and the diameter of each of the plurality of small holes is 0.1-0.3 mm;

[0019] The filter element is made of quartz sand.

[0020] According to a specific embodiment of the present invention, along the length direction of the bottle body, the distance between the filter sheet and the second opening is less than the distance between the filter sheet and the first opening.

[0021] According to a specific embodiment of the present invention, it also includes a connecting pipe;

[0022] In the first state, one end of the connecting pipe is configured to be connected to the third air port, and the other end of the connecting pipe is configured to be connected to the second air port, so that the second air port and the third air port are in communication.

[0023] According to a specific embodiment of the present invention, the first cover, the second cover, and the third cover are made of polytetrafluoroethylene.

[0024] By adopting the above technical solution and using polytetrafluoroethylene as the material for the first, second, and third covers, the corrosion resistance of the first, second, and third covers can be effectively improved.

[0025] According to a specific embodiment of this utility model, the gas is nitrogen.

[0026] The present invention also discloses a purification device, comprising:

[0027] Multiple purification containers as described in any of the above specific embodiments;

[0028] The purification device has a fourth state and a fifth state;

[0029] In the fourth state, the first opening of one of the plurality of purification containers is connected to the first cover, and the second opening is connected to the second cover; the first opening of the remaining purification containers is connected to a second cover, and the second opening is connected to a second cover; the third air port of the second cover of the second opening of each of the plurality of purification containers is connected to the third air port of the second cover of the first opening of another of the plurality of purification containers.

[0030] In the fifth state, the first opening of each of the plurality of purification containers is open, the second opening of each of the plurality of purification containers is connected to the second cover, and the third air vents of the plurality of second covers are interconnected.

[0031] By adopting the above technical solution, multiple purification containers are interconnected, thus connecting them in series. Therefore, by simply introducing gas into the first air port of the first cover of the first opening of one purification container, the gas can pass through the containing chambers of multiple purification containers in sequence, thereby ensuring that the materials to be purified and the reagents in each purification container are in full contact, improving the purification effect. As a result, a large number of materials to be purified can be processed simultaneously, effectively improving the purification efficiency.

[0032] According to a specific embodiment of the present invention, it includes multiple connecting pipes, in the fourth state,

[0033] One end of each of the connecting tubes is connected to the third air port of the second cover of the first opening of the remaining purification containers in the plurality of purification containers, and the other end is connected to the third air port of the second cover of the second opening of one of the plurality of purification containers.

[0034] The present invention also discloses a purification device, characterized in that it comprises:

[0035] The purification container described in any of the above specific embodiments;

[0036] Processing rack, the processing rack comprising:

[0037] The placement section is configured to place the bottle body;

[0038] A collection section, located below the placement section along the height direction, is configured to place a collection container, which is configured to collect the reagent within the receiving cavity;

[0039] Along the length of the purification container, the placement part is provided with a through hole, which is configured to allow the first opening of the bottle to pass through. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0056] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0057] refer to Figure 1 This application provides a purification device 200, which includes a purification container 100 and a processing rack 210. The purification container 100 is used to store macroporous resin 10 ( Figure 4 (shown in) and reagent 20 ( Figure 4 (As shown in the diagram). The processing rack 210 is used to hold the purification container 100. The embodiments of this application do not impose special limitations on the specific type of reagent 20; for example, in some possible implementations, reagent 20 may be hydrochloric acid, sodium hydroxide solution, etc.

[0058] It should be noted that the purification device 200 provided in this application embodiment can not only be used to purify macroporous resin 10, but also can be applied to any other material that needs to be soaked and ultimately requires solid-liquid separation. For the sake of detailed description of the purification device 200 of this application, this application embodiment uses macroporous resin 10 as an example for illustration.

[0059] The purification container 100 will now be described in detail with reference to the accompanying drawings.

[0060] refer to Figure 2 and Figure 3 The purification container 100 includes a bottle body 110, a filter 120, a first cover 130, a second cover 140, a third cover 150, and a connecting pipe 160.

[0061] The bottle body 110 has a receiving cavity 111, a first opening 112, and a second opening 113. The receiving cavity 111 is used to receive the macroporous resin 10 and the reagent 20. Along the length direction X of the bottle body 110, the first opening 112 of the bottle body 110 is located at one end of the bottle body 110, and the second opening 113 is located at the other end of the bottle body 110.

[0062] For example, the first cover 130 can be detachably connected to the first opening 112, the second cover 140 can be detachably connected to the first opening 112 or the second opening 113, and the third cover 150 can be detachably connected to the first opening 112 or the second opening 113.

[0063] Continue to refer to Figure 2 and Figure 3 In this embodiment, the first cover 130 is provided with a first air port 131 and a second air port 132, which are used to introduce nitrogen into the receiving cavity 111. The second cover 140 is provided with a third air port 141, which is used to discharge nitrogen from the receiving cavity 111. The third cover 150 is a sealed cover, that is, the third cover 150 is not provided with an air inlet or outlet.

[0064] It should be noted that nitrogen is an inert gas and does not readily undergo chemical reactions. Therefore, introducing nitrogen into the receiving cavity 111 can effectively ensure sufficient contact between reagent 20 and macroporous resin 10 without affecting either reagent 20 or macroporous resin 10. It should also be noted that the type of gas introduced into the receiving cavity 111 is not specifically limited in this embodiment, as long as it ensures sufficient contact between reagent 20 and macroporous resin 10 without affecting either.

[0065] Continue to refer to Figure 2 and Figure 3 The filter 120 is located within the receiving cavity 111, and along the length X of the bottle body 110, the distance L1 from the filter 120 to the first opening 112 is less than the distance L2 from the filter 120 to the second opening 113. In other words, along the length X of the bottle body 110, the filter 120 is closer to the first opening 112. The filter 120 has multiple small holes 121 through which reagent 20 can pass, while macroporous resin 10 cannot. Therefore, after the macroporous resin 10 has been purified, reagent 20 can be discharged from the receiving cavity 111 through the filter 120, thereby separating reagent 20 and macroporous resin 10.

[0066] For example, in this embodiment, the aperture of the orifice 121 is 0.1-0.3 mm, preferably 0.2 mm. However, this embodiment does not impose a special limitation on the aperture of the orifice 121, and it can be adaptively adjusted according to different materials to be purified so that the materials to be purified cannot pass through the filter 120.

[0067] For example, the filter element 120 is made of quartz sand, which has high corrosion resistance and can resist the erosion of various chemicals, thus maintaining a stable filtration effect. However, this application embodiment does not impose special restrictions on the material of the filter element 120, as long as it is corrosion-resistant and can effectively filter.

[0068] The following details the usage process of the purification container 100 according to an embodiment of this application.

[0069] refer to Figure 2 and Figure 4 First, along the height direction X (when the bottle 110 is in use, the height direction is the same as the length direction of the bottle 110, both being direction X), position the second opening 113 above and the first opening 112 below, and connect the third cap 150 to the first opening 112, while keeping the second opening 113 open. At this time, the purification container 100 is in the third state. In the third state, neither the first cap 130 nor the second cap 140 is connected to the first opening 112 or the second opening 113 of the bottle 110, and the third cap 150 is connected to the first opening 112.

[0070] Next, refer to Figure 5 The macroporous resin 10 to be purified and reagent 20 are poured into the receiving cavity 111 through the second opening 113. Then, as... Figure 6 As shown, the second cover 140 is connected to the second opening 113, and the second end 162 of the connecting pipe 160 is connected to the third air port 141 of the second cover 140.

[0071] refer to Figure 7 and combined Figure 6 The purification container 100 is inverted so that the third cover 150 is positioned above the receiving cavity 111 along the height direction X, and the second cover 140 is positioned below the receiving cavity 111 along the height direction X. Next, refer to... Figure 8 Replace the third cover 150 with the first cover 130, and connect the first end 161 of the connecting pipe 160 to the second air port 132 of the first cover 130. Connect the first air port 131 to the external air pipe 170. One end of the external air pipe 170 extends into the container 111 through the first air port 131, and one end of the external air pipe 170 is located between the filter 120 and the first cover 130. The external air pipe 170 is used to introduce nitrogen gas into the container cavity 111.

[0072] Finally, refer to Figure 3 and combined Figure 8 The purification container 100 is then inverted again so that the second cover 140 is positioned above the receiving cavity 111 along the height direction X, and the first cover 130 is positioned below the receiving cavity 111 along the height direction X. This places the purification container 100 in a position as follows: Figure 3In the first state shown, the first cover 130 is connected to the first opening 112, the second cover 140 is connected to the second opening 113, and the second air port 132 of the first cover 130 and the third air port 141 of the second cover 140 are connected through a connecting pipe 160 (that is, the first end 161 of the connecting pipe 160 is connected to the second air port 132, and the second end 162 is connected to the third air port 141). The first air port 131 of the first cover 130 is connected to an external air pipe 170, and nitrogen gas is introduced into the receiving cavity 111 through the external air pipe 170.

[0073] For example, continue to refer to Figure 3 After nitrogen enters the receiving cavity 111 through the first gas port 131, it flows along the length direction X of the bottle body 110 to the second cover 140, and then enters the connecting pipe 160 through the third gas port 141 of the second cover 140. Then, the nitrogen flows along the connecting pipe 160 from the second end 162 to the first end 161, and then flows back into the receiving cavity 111 through the second gas port 132 of the first cover 130, so as to realize the circulation of nitrogen.

[0074] After introducing nitrogen gas, the purification container 100 can be placed on the processing rack 210 and allowed to stand for 8-12 hours to allow the reagent 20 to fully absorb the impurities in the macroporous resin 10. It should be noted that the supply of nitrogen gas can be stopped or continued during the standing process, and this embodiment does not impose any special restrictions on this.

[0075] For example, refer to Figure 1 The processing rack 210 includes a placement section 220 and a collection section 230. The placement section 220 is configured to place the purification container 100. When the purification container 100 is placed on the processing rack 210, the length direction of the purification container 100 is the same as the height direction of the processing rack 210.

[0076] For example, the placement portion 220 and the collection portion 230 are plate-shaped structures. Along the height direction X, the placement portion 220 is located above the collection portion 230. And along the height direction X, the placement portion 220 and the collection portion 230 define a collection space 232. The collection space 232 is used to accommodate a collection container 231, specifically, the collection container 231 is placed on the collection portion 230. The collection container 231 is configured to collect the reagent 20 within the receiving cavity 111.

[0077] Continue to refer to Figure 1 The placement part 220 is provided with four through holes 221, each through hole 221 extending through the placement part 220 along the height direction X. The through holes 221 are configured to allow the first opening 112 of the bottle body 110 to pass through.

[0078] It should be noted that the number of through holes 221 on the placement part 220 is not specifically limited in this embodiment. For example, in other possible implementations, the number of through holes 221 may be one, two, three, or five, etc.

[0079] In this embodiment of the application, the processing rack 210 further includes a limiting part 240. Specifically, the limiting part 240 is a plate-shaped structure, and along the height direction X, the limiting part 240 is located above the placement part 220. The limiting part 240 is provided with four limiting holes 241. Each limiting hole 241 is opposite to a through hole 221 along the height direction X. Each limiting hole 241 allows the bottle body 110 of a purification container 100 to pass through, thereby forming a horizontal limiting on the bottle body 110 so that the purification container 100 can be placed more stably on the processing rack 210.

[0080] It should be noted that the present application embodiment does not impose any special restrictions on the number of limiting holes 241 on the limiting part 240, as long as the number of limiting holes 241 is the same as the number of through holes 221, and each limiting hole 241 is opposite to a through hole 221 along the height direction X.

[0081] After the macroporous resin 10 has been purified, the first cover 130 at the bottom of the purification container 100 is opened, thereby putting the purification container 100 into a second state to discharge the reagent 20 from the receiving cavity 111. In the second state, the second cover 140 is connected to the second opening 113, and the first cover 130 is not connected to the first opening 112, so that the reagent 20 flows into the collection container 231 below through the first opening 112.

[0082] Since the receiving cavity 111 is equipped with a filter 120, and the macroporous resin 10 cannot pass through the small holes 121 on the filter 120, the macroporous resin 10 remains within the receiving cavity 111 during this process. This achieves the separation of the macroporous resin 10 and the reagent 20, thereby obtaining the purified macroporous resin 10.

[0083] The purification device 200 provided in this application embodiment, after loading resin 10 and reagent 20 into purification container 100, only requires inverting the bottle body 110 twice to attach the first cap 130 to the first opening 112 and the second cap 140 to the second opening 113 of purification container 100. After introducing nitrogen gas, it can be placed on processing rack 210 for settling. No manual monitoring is required during the settling process. Once settling is complete, simply opening the first cap 130 to open the first opening 112 allows reagent 20 to be discharged from the receiving cavity 111. Compared to traditional Soxhlet extractors, the purification device provided in this application embodiment is simpler to operate.

[0084] Furthermore, since a filter 120 is provided inside the bottle body 110 in this embodiment, the macroporous resin 10 remains inside the receiving cavity 111 of the bottle body 110 after the reagent 20 is discharged from the receiving cavity 111, thus enabling the temporary storage of the macroporous resin 10.

[0085] In some possible implementations, before discharging reagent 20, the second end of the connecting tube 160 can be separated from the third air port 141 of the second cover 140, thereby effectively avoiding the generation of negative pressure during the discharge of reagent 20 and improving the discharge efficiency of reagent 20.

[0086] In one possible implementation, the connection between the second end 162 of the connecting tube 160 and the first cover 130 can be disconnected, and nitrogen gas can be introduced into the third air port 141 of the second cover 140 through the second end 162 of the connecting tube 160, so that nitrogen gas enters the containing cavity 111 to achieve nitrogen blowing, thereby accelerating the discharge of reagent 20.

[0087] In some other possible implementations, before the reagent 20 is discharged, nitrogen gas can be directly introduced into the third vent 141 of the second cover 140 of the second opening 113 of the purification container 100 through an external venting pipe to achieve nitrogen blowing, thereby accelerating the discharge of the reagent 20.

[0088] For example, the capacity of the purification container 100 in this embodiment of the application is 1500 ml, but it is not limited to this. In other possible implementations, the capacity of the purification container 100 may also be 1000 ml, 1600 ml, 2000 ml or 3000 ml, etc., and can be adapted according to actual needs.

[0089] In this embodiment, the first cover 130, the second cover 140, and the third cover 150 are all made of polytetrafluoroethylene (PTFE). PTFE has high corrosion resistance and is not easily corroded by reagent 20. This embodiment does not impose special limitations on the materials of the first cover 130, the second cover 140, and the third cover 150. In other possible embodiments, the first cover 130, the second cover 140, and the third cover 150 can also be made of other corrosion-resistant materials.

[0090] For example, in the embodiments of this application, the first cap 130, the second cap 140 and the third cap 150 are connected to the bottle body 110 by threads.

[0091] For example, in this embodiment of the application, the bottle body 110 is made of glass.

[0092] In some other possible implementations, a valve may be provided inside the first cover 130. Thus, when it is necessary to ventilate the receiving cavity 111, the valve inside the first cover 130 can be opened; when it is not necessary to ventilate the receiving cavity 111, the valve inside the first cover 130 can be closed. Therefore, the first cover 130 itself can perform the function of the third cover 150. That is, in this embodiment, before venting nitrogen into the receiving cavity 111, the third cover 150 is not required to vent nitrogen into the receiving cavity 111.

[0093] In some possible implementations, refer to Figure 9 Multiple purification containers 100 can be connected in series to put the purification device 200 in the fourth state.

[0094] The following explanation uses four purification containers 100 (purification container 100a, purification container 100b, purification container 100c, and purification container 100d) connected in series as an example. In the fourth state, the first opening 112 of purification container 100a is connected to the first cover 130, and the second opening 113 is connected to the second cover 140. The first opening 112 of each of the other purification containers 100 (i.e., purification container 100b, purification container 100c, and purification container 100d) is connected to a second cover 140, and the second opening 113 is connected to a second cover 140.

[0095] For example, the third air port 141 of the second cover 140 of the second opening 113 of each of the remaining purification containers 100 (i.e., purification containers 100b, 100c and 100d) is connected to the third air port 141 of the second cover 140 of the first opening 112 of the other purification container 100 via a connecting pipe 160. Specifically, the third air port 141 of the second cover 140 of the first opening 112 of the purification container 100b is connected to the third air port 141 of the second cover 140 of the second opening 113 of the purification container 100a via a connecting pipe 160a; the third air port 141 of the second cover 140 of the first opening 112 of the purification container 100c is connected to the third air port 141 of the second cover 140 of the second opening 113 of the purification container 100b via a connecting pipe 160b; the third air port 141 of the second cover 140 of the first opening 112 of the purification container 100c is connected to the third air port 141 of the third cover 140 of the second opening 113 of the purification container 100c via a connecting pipe 160c; and the second air port 132 of the first cover 130 of the first opening 112 of the purification container 100a is connected to the third air port 141 of the second cover 140 of the second opening 113 of the purification container 100d via a connecting pipe 160d. This allows for the connection of purification containers 100a, 100b, 100c, and 100d in series.

[0096] For example, before the four purification containers 100 are allowed to stand, nitrogen gas is introduced into the purification container 100a through the external gas pipe 170. After the nitrogen gas flows into the purification container 100a, it flows sequentially through the connecting pipe 160a, purification container 100b, connecting pipe 160b, purification container 100c, connecting pipe 160c, purification container 100d, and connecting pipe 160d. Finally, it flows back into the purification container 100a through the second gas port 132 of the first cover 130 of the first opening 112 of the purification container 100a. This achieves nitrogen circulation, allowing the macroporous resin 10 and reagent 20 in each of the four purification containers 100 to fully contact each other, effectively improving the purification effect on the macroporous resin 10.

[0097] Continue to refer to Figure 10 After settling, remove the first cover 130 of purification container 100a and the second cover 140 of the first opening 112 of purification containers 100b, 100c and 100d, so that the purification device 200 is in the fifth state.

[0098] Specifically, in the fifth state, the first opening 112 of each purification container 100 is open, and the second opening 113 of each purification container 100 is connected to a second cover 140, so that the reagent 20 can be discharged from the purification container 100 through the first opening 112, thereby achieving the separation of the reagent 20 from the macroporous resin 10.

[0099] Furthermore, in some possible implementations, reference continues to be made to... Figure 10 In the fifth state, each purification container 100 is connected via a nitrogen blow-through pipe 180, so that the second cover 140 of the second opening 113 of each purification container 100 is interconnected. Specifically, the nitrogen blow-through pipe 180 includes four branch pipes 181, each branch pipe 181 being connected to the third air port 141 of the second cover 140 at the second opening 113 of a purification container 100, thereby introducing nitrogen gas into each purification container 100 through the nitrogen blow-through pipe 180 to facilitate reagent discharge.

[0100] It should be noted that the number of branch pipes 181 of the nitrogen purging pipe 180 is not specifically limited in this embodiment and can be adjusted according to actual needs, but the number of branch pipes 181 of the nitrogen purging pipe 180 should be the same as the number of purification containers 100. For example, in some possible embodiments, the number of branch pipes 181 of the nitrogen purging pipe 180 is two, three, five, or six, etc.

[0101] The purification device 200 provided in this application embodiment effectively increases the processing capacity of macroporous resin 10 by connecting multiple purification containers 100 in series.

[0102] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
