Description
Technical field
The utility model relates to a kind of chromatographic technique, is specifically related to a kind of low pressure chromatography column packing device.
Background technology
Conventional column chromatography for separation technology is a kind of isolation technics with the longest history in the chromatography, most widely used.Conventional column chromatography for separation technology has outstanding advantages such as simple to operate, flexible, that column capacity is big, adaptability is strong, makes it keep one seat all the time in various separation sciences field.But its limitation when productions such as chemical industry also is clearly: the one, and dress post difficulty, the general dry column-packing that uses during industrial production, dry column-packing is easy to generate dust, and floating dust can enter the human lung and then be detrimental to health; The 2nd, during dry column-packing, filler is packed into and is full of air in the chromatographic column rear pillar, and the bubble in the column chromatography center pillar has very big influence to the chromatography effect, needs to use a large amount of solvents drive bubble away, the solvent of wasting again consuming time; The 3rd conventional post unloads the filler difficulty, needs manually to draw out filler from post, and residual solvent, filler dust etc. have a strong impact on personnel's health in length consuming time and the filler.The 3rd, also there is the inconvenient problem of cleaning in conventional post, because column volume is big during industrial production, be by bolting around the flange, need great amount of manpower if the dismounting flange cleans, and lower flange is heavy, needs at least more than the four-player during dismounting, still can not get rid of the risk that lower flange is slipped out of the hand and dropped, so generally do not open cleaning after conventional chromatographic column installs, post was interior when used next time so just inevitably can residually go up the useless filler of criticizing, and shines into the pollution of feed liquid.
This shows that there are many defectives in conventional chromatographic column isolation technics, remains to be improved.Defective in view of above-mentioned this conventional chromatographic column dress post, the utility model purpose aims to provide a kind of novel low post equipment that press-fits, simple to operate, safe and reliable, can clean easily, load and unload, reduce the solvent use amount, reduce the EHS risk, can effectively guarantee the filling effect of chromatography again, reduce the cost of labor of loading.
The utility model content
The technical solution of the utility model is: a kind of low pressure chromatography column packing device, it is characterized in that comprising fluid power system and chromatography column system, and wherein said fluid power system is made up of hydraulic cylinder 1, Pneumatic oil pump 2, oil pump control panel 3, fuel tank 4; Described chromatography column system is made up of column jecket 6, piston 7, upper flange 8, lower flange 9, and described two systems are connected by piston 7.
Lower flange 9 has eight screws, and four Pear-Shaped holes 11 are arranged on the upper flange 8.
The utility model low pressure chromatographic column improves at the upper flange nut structure, see Fig. 2, Fig. 3 for details, low pressure chromatographic column upper flange is realized function by four common screws of symmetry are made into the calabash shape screw, and this Screw hole structure has been simplified the operation of loading and unloading lower flanges, and safety coefficient is higher.During use, four screw rods lower flange of packing into symmetry passes the Pear-Shaped hole to the screw rod on the lower flange again, rotates lower flange and makes its screw rod be stuck in the small bore end in Pear-Shaped hole, and lower flange just can be suspended on the upper flange like this, tightens screw rod then and just can finish assembling.Because the architecture advances of upper flange makes lower flange can be relatively easy to loading and unloading, for second improvement of the present utility model provides condition.This utility model low pressure chromatographic column is made of hydraulic cylinder, Pneumatic oil pump, oil pump control panel, fuel tank, support bar, column jecket, piston, upper flange, lower flange etc.With respect to prior art, owing to adopted hydraulic system, can realize wet method dress post.After modified low pressure chromatographic column cleans assembling, filler is poured in the airtight agitator tank, add a certain amount of solvent, pump in the chromatographic column after stirring, open waste valve, by hydraulic system filling compaction, realized the filling of chromatographic column easily, because whole process is all finished in dicyandiamide solution, avoided the generation of bubble, thus just do not need to drive bubble with solvent yet, and because certain pressure is arranged during the dress post, can be chromatographic column dress more even, closely knit, thereby the conventional relatively chromatographic column of the chromatographic column efficient of post will be got well a lot.
When unloading post; utility model low pressure chromatographic column need not artificial excavation and filling material; column packing is washed in the water top by elder generation; unscrew the screw rod on the upper flange, only need to rotate lower flange then and make screw rod forward the macropore position of calabash shape screwed hole to, draw off lower flange; with hydraulic system piston is moved downward; filler in the post is extruded, effectively raise operating efficiency like this, and operating personnel have been carried out effective protection.The utility model has solved the shortcoming of conventional post effectively in sum, has improved operating efficiency, and the post of filling is imitated high, reduces effectively and loads cost.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below describes in detail with preferred embodiment example of the present utility model and conjunction with figs..
The specific embodiment of the present utility model is provided in detail by following embodiment and accompanying drawing thereof.
