Description

Technical Field

[0001] The utility model belongs to the technical field of plant decolorization equipment, in particular to a plant decolorization chromatography resin column. Background Art

[0002] The main methods of plant decolorization include macroporous resin adsorption, water extraction and alcohol precipitation, extraction and membrane separation. Among them, macroporous resin adsorption technology has great advantages due to its large adsorption capacity, good selectivity and easy regeneration.

[0003] The adsorption capacity of a chromatography column using macroporous resin as the adsorption material is negatively correlated with the diameter-to-height ratio of the resin column, that is, when the diameter of the chromatography column remains unchanged, the higher the macroporous resin chromatography column is, the stronger the adsorption capacity of the chromatography column using the macroporous resin as the adsorption material is. Therefore, in order to improve the adsorption capacity of the chromatography column, and thus improve the ability of the chromatography column to decolorize plants, it is usually necessary to make the resin column as high as possible.

[0004] However, when the overall setting of the resin column in the chromatography column is relatively high, firstly, the macroporous resin cannot be filled evenly, resulting in unstable plant decolorization efficiency; secondly, the macroporous resin at a high position will exert tremendous pressure on the macroporous resin at a low position, causing damage or agglomeration of the macroporous resin at the low position, thereby resulting in the inability to maximize the decolorization efficiency of the chromatography column; finally, when the macroporous resin at a low position needs to be replaced, all the macroporous resins need to be dug out before the macroporous resin at the low position can be replaced, thus wasting the intact macroporous resin at a high position and causing a waste of labor and material costs for the enterprise.

[0040] Example

[0041] like Figures 1 to 5 As shown, an embodiment of the present application provides a plant decolorization chromatography resin column, comprising a chromatography column housing 1, a top cover 2 covering the top end of the chromatography column housing 1, and a base 3 connected to the bottom end of the chromatography column housing 1.

[0043] Wherein, the elastic member 17 is a tension spring.

[0044] The chromatography column housing 1 is provided with a bottom chromatography column 4, a top chromatography column 5 and at least one middle chromatography column 6. The bottom chromatography column 4 is arranged at one end of the chromatography column housing 1 close to the base 3, the top chromatography column 5 is arranged at one end of the chromatography column housing 1 close to the top cover 2, and the middle chromatography column 6 is placed between the bottom chromatography column 4 and the top chromatography column 5. When the top cover 2 is covered directly above the chromatography column housing 1, the bottom end of the top cover 2 is located in the chromatography column housing 1 and abuts against the top chromatography column 5. The bottom chromatography column 4, the top chromatography column 5 and the middle chromatography column 6 are each provided with a filter screen 10 at one end close to the base 3.

[0045] Specifically, slide grooves 11 are provided on two opposite sides of the chromatography column housing 1, and sliders 12 are provided on two opposite sides of the outer side of the bottom chromatography column 4, two opposite sides of the outer side of the top chromatography column 5, and two opposite sides of the outer side of all the middle chromatography columns 6. The bottom chromatography column 4, the top chromatography column 5, and the middle chromatography column 6 are all slidably mounted inside the chromatography column housing 1 through the sliders 12 and the slide grooves 11.

[0046] Among them, the bottom chromatography column 4, the top chromatography column 5 and the middle chromatography column 6 are all filled with macroporous resin, the macroporous resin in each chromatography column is located above each filter 10, and the thickness of the corresponding macroporous resin layer of the chromatography column is less than the height of the chromatography column. In order to prevent the filter 10 from being corroded by the solution during long-term use, the filter 10 is a quartz sand filter.

[0047] The bottom chromatography column 4 is provided with a first annular protrusion 7 at one end away from the base 3, the top chromatography column 5 is provided with a first annular groove 8 at one end away from the top cover 2, the middle chromatography column 6 is provided with a second annular groove matching the first annular protrusion 7 at one end close to the bottom chromatography column 4, and a second annular protrusion 9 matching the first groove is provided at one end close to the top chromatography column 5, and the second annular protrusion 9 and the second annular groove are also matched, so the top chromatography column 5, at least one of the middle chromatography columns 6 and the bottom chromatography column 4 are sequentially plugged in through the first annular groove 8, the second annular protrusion 9, the second annular groove and the first annular protrusion 7.

[0048] Specifically, in order to improve the sealing between the bottom chromatography column 4 and the middle chromatography column 6, between the connected middle chromatography columns 6, and between the middle chromatography column 6 and the top chromatography column 5, sealing rings are provided in the first annular groove 8 and the second annular groove.

[0049] In some embodiments, in order to improve the disassembly and replacement of the bottom chromatography column 4, the top chromatography column 5 and the middle chromatography column 6, lifting ears 13 are provided on the first annular protrusion 7, the second annular protrusion 9 and the top of the top chromatography column 5 on opposite sides, and the first annular groove 8 and the second annular groove are provided with lifting ear grooves matched with the lifting ears 13 on opposite sides. When the bottom chromatography column 4, the top chromatography column 5 and the middle chromatography column 6 need to be disassembled or replaced, the bottom chromatography column 4, the top chromatography column 5 and the middle chromatography column 6 can be quickly and conveniently taken out by hooking the lifting ear 13 with the help of a long hook. It should be noted that when the lifting ear grooves are provided in the first annular groove 8 and the second annular groove, the sealing rings still exist in the first annular groove 8 and the second annular groove, and at this time the sealing rings are still in contact with the first annular groove 8 and the second annular groove.

[0050] In some embodiments, because the chromatography column is usually made of stainless steel in industrial production, the liquid level inside cannot be seen. In order to prevent the sample liquid and eluent from overflowing due to excessive speed of adding, an anti-overflow component is further provided at one end of the chromatography column housing 1 close to the top cover 2. The anti-overflow component includes a float 18, a connecting rod 19, an insulating chute 20, an electrode 21, a power supply 22, a warning light 23 and a buzzer 24. The float 18 is arranged in the top chromatography column 5, and the insulating chute 20 is vertically arranged on the inner side of the chromatography column housing 1. One end of the connecting rod 19 is connected to the float 18, and the other end is connected to a metal slider slidably connected to the insulating chute 20. The electrode 21 is arranged at one end of the insulating chute 20 close to the top cover 2. The other end of the electrode 21, the warning light 23, the buzzer 24 and one end of the power supply 22 are connected in series in sequence, and the other end of the power supply 22 is connected to the metal slider.

[0051] Among them, the float 18 is arranged in the top chromatography column 5. When the liquid level in the top chromatography column 5 is too high, the float 18 drives the connecting rod 19 to rise, so that the metal slider rises and contacts the electrode 21, so that the circuit of the anti-overflow component is turned on. At this time, the power supply 22 supplies power to the warning light 23 and the buzzer 24, the warning light 23 lights up, and the buzzer 24 makes a sound. The staff can adjust or close the valve on the liquid inlet pipe according to the above prompts to prevent the sample liquid or eluent from overflowing.

[0052] Since the sample liquid and the eluent are at a certain height from the macroporous resin in the top chromatography column 5 when they flow out from the outlet of the liquid inlet pipe, the sample liquid or the eluent will impact the macroporous resin in the top chromatography column 5, causing splashing, and at the same time, the shape of the resin column in the chromatography column is also destroyed, thereby affecting the efficiency of the chromatography column in decolorizing plants. In some embodiments, the bottom end of the top cover 2 is provided with an anti-splashing component, and the anti-splashing component includes a perforated plate 25 and a conical guide plate 26;

[0053] The perforated plate 25 is connected to the bottom end of the top cover 2 and is provided with a plurality of guide holes 27;

[0054] The conical guide plate 26 is disposed at one end of the perforated plate 25 close to the top chromatography column 5 , and the end with a larger diameter is connected to the perforated plate 25 .

[0055] In summary, the embodiments of the present application respectively arrange the top cover and the base at the top and the bottom of the chromatography column housing, arrange a bottom chromatography column, a top chromatography column and at least one middle chromatography column in the chromatography column housing, and arrange a filter screen at one end of the bottom chromatography column, the top chromatography column and the middle chromatography column close to the base, so as to divide a higher chromatography column as a whole into several chromatography columns. This solves the technical problems in the prior art that the decolorization effect of the chromatography column on plants is unstable and the decolorization efficiency cannot be maximized because the resin column in the chromatography column is too high as a whole, and when the low-level macroporous resin needs to be replaced, all the macroporous resins need to be dug out, resulting in a waste of labor costs and material costs for the enterprise.

[0056] The foregoing descriptions of specific exemplary embodiments of the present invention are for the purpose of explanation and illustration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
