Abstract
The utility model discloses a separable chromatographic column which comprises a column body part (1) and a sand core funnel part (2), wherein a seal washer (7) is padded between a flange surface (3) at the lower end of the column body part (1) and a flange surface (4) at the upper end of the sand core funnel part (2), the column body part (1) is connected with the sand core funnel part (2) by a loose flange (5), an adaptive sand core sieve plate (6) is arranged in the sand core funnel part (2), and a control piston (8) is arranged at the outlet part of the lower end of the sand core funnel part (2). The structural design of the separable chromatographic column is reasonable. The chromatographic column can be made with various specifications, and particularly can be made into a longer column body. The chromatographic column can be conveniently disassembled and washed, materials can be conveniently discharged, and parts can be used alternatively. The cost can be saved.
Description
Technical field
The utility model relates to a kind of separator of compound, is specifically related to a kind of detachable chromatographic column that is used to separate organic compound.
Background technology
In the medicine production and drug research and development process of pharmacy corporation, often need separate purification to compound synthetic or that extraction obtains, obtain the unification compound or have a compounds of same structure parent nucleus, purify for the separation of organic compound at present, chromatography is a kind of method comparatively commonly used, chromatography is commonly used to chromatographic column, when carrying out large-scale production, pharmacy corporation just needs the bigger chromatographic column of specification, but the chromatographic column of prior art is generally non-removable integral structure, this specification is bigger, and the chromatographic column that cylinder is long brings a lot of inconvenience to discharging and cleaning, be difficult to the chromatographic column cleaning clean, thereby pollute compound to be separated, and the bigger chromatographic column price of specification is more expensive, after chromatographic column partly damages, whole chromatographic column will be scrapped, and cost is higher.Therefore necessaryly design a kind of extensive separation and purification that is fit on the basis of existing technology, clean chromatographic column easily.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of reasonable in design to be provided, to clean convenience, discharging convenience, the interchangeable detachable chromatographic column of parts.
Technical scheme: in order to realize above purpose, technical solution adopted in the utility model is:
A kind of detachable chromatographic column, it comprises: cylinder part and sand core funnel part, wherein the flange face of cylinder part lower end is connected by lap joint flange with the flange face of sand core funnel part upper end, is placed with suitable core sieve plate in the described sand core funnel part.
As preferred version, above-described detachable chromatographic column wherein is lined with the caulking gum packing ring between the flange face of the flange face of cylinder part lower end and sand core funnel part upper end, connects by lap joint flange and by screw then.
As preferred version, above-described detachable chromatographic column wherein is provided with control piston in the exit, lower end of sand core funnel part.
As preferred version, above-described detachable chromatographic column, wherein the core sieve plate is placed in the sand core funnel part, and the shape of core sieve plate and sand core funnel shape are suitable, and the periphery of core sieve plate contacts with the inner sealing of sand core funnel, thereby can prevent to leak under the parting material.
The detachable chromatographic column that the utility model provides, the diameter of whole chromatographic column can reach 5cm ~ 50cm, and length can reach 0.5 to 3m.Wherein chromatographic column can be made by the plastics of glass or acid and alkali-resistance.
The detachable chromatographic column operation principle that the utility model provides is: during use, the core sieve plate is placed in the sand core funnel part, fill up upper sealing washer between the flange face with cylinder part and sand core funnel part then, by the lap joint flange on cylinder part and the sand core funnel part cylinder partly partly is connected with sand core funnel then, and be screwed, then parting material is filled into column body, control piston is opened, compound is separated, after separating end, unclamp trip bolt and lap joint flange, parting material is laid down, can clean cylinder part and sand core funnel part then easily.
Beneficial effect: the detachable chromatographic column that the utility model provides is compared with prior art and is had the following advantages:
The detachable chromatographic column that the utility model provides, reasonable in design, can be prepared into the chromatographic column of all size, especially can be prepared into the long chromatographic column of cylinder, wherein the cylinder part is connected by flange face with the sand core funnel part, dismounting and cleaning are convenient, be lined with sealing ring between two flange faces, air-tightness is good, and the cylinder of chromatographic column part and sand core funnel part can mutual alternative be used, therefore can solve owing to certain part is damaged the shortcoming that causes whole chromatographic column to be scrapped, can save cost.
Description of drawings
The structural representation of the detachable chromatographic column longitudinal section that Fig. 1 provides for the utility model.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
Embodiment
As shown in Figure 1, detachable chromatographic column described in the utility model: it comprises: cylinder part (1) and sand core funnel part (2), wherein be lined with caulking gum packing ring (7) between the flange face (4) of flange face (3) of cylinder part (1) lower end and sand core funnel part (2) upper end, and the flange face (3) of cylinder part (1) lower end is connected by lap joint flange (5) with the flange face (4) of sand core funnel part (2) upper end, be placed with suitable core sieve plate (6) in the described sand core funnel part (2), and be provided with control piston (8) in the exit, lower end of sand core funnel part (2).
Above-mentioned described detachable chromatographic column, the diameter of cylinder part (1) can be 5cm ~ 50cm, and the length of whole chromatographic column can be 0.5 to 3m.Cylinder part (1) and sand core funnel part (2) are made by the plastics of glass material or acid and alkali-resistance.
During the actual use of the detachable chromatographic column that the utility model provides, at first core sieve plate (6) is placed in the sand core funnel part (2), fill up upper sealing washer (7) between the flange face with cylinder part (1) and sand core funnel part (2) then, then by the lap joint flange (5) on cylinder part (1) and the sand core funnel part (2) with cylinder part (1) and sand core funnel partly (2) be connected, and be screwed, then parting material is filled into column body, control piston (8) is opened, adding eluent separates compound, after separating end, unclamp trip bolt and lap joint flange (5), parting material is laid down, can clean cylinder part (1) and sand core funnel part (2) then easily, reuse.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
