Description
Technical field
The utility model relates to a kind of for three oil cylinders in preparing chromatograph in industry and hydraulic pressure mixing compression set, belongs to liquid chromatogram field.
Background technology
Dynamic axial compression technology is generally acknowledged unique technology that can keep good separation effect in the column chromatography of various scale, and it is the column packing technique of current preparing chromatograph in industry field the best.Dynamic axial compression column separating effect is suitable with analytical column separating effect, can load various types of homogenate simultaneously.
Traditional dynamic axial compression column is top oil cylinder and piston component being placed in column casing, moving up and down by oil cylinder, thus the object reaching homogenate in compacting column casing.Along with the develop rapidly of chromatographic field, the conditions such as the design height of column casing and the use pressure of column casing become diversity, and this extreme design condition, make traditional high pressure dynamic axial compression column not meet instructions for use.
Therefore, how designing and meet the dynamic axial compression column that longer, higher column casing uses the conditions such as pressure, is the difficult problem that three oil cylinders will solve with hydraulic pressure mixing compression set.
Summary of the invention
The purpose of this utility model be overcome that traditional dynamic axial compression column column casing is longer, column casing uses the more high defect of pressure, provides the mixing compression set that a kind of separating effect is suitable, structure is simple, build is light, easy to operate.
The technical solution adopted in the utility model is as follows:
Be applied to the mixing compression set that preparing chromatograph in industry is separated, by column casing, oil cylinder, crossbeam, sample feed port, attaching nut, piston brace rod, connecting rod fairlead, upper end cover, piston thrust ring, piston, enter homogenate ball valve, go out homogenate ball valve, bottom end cover, sample discharging opening, supporting leg, safety valve, water inlet ball valve, Pressure gauge and delivery port ball valve form.
Fix upper end cover above column casing, fixed connecting rod fairlead, safety valve, water inlet ball valve, Pressure gauge and delivery port ball valve above upper end cover, below connects piston thrust ring by screw; Fix bottom end cover below column casing, below bottom end cover, be provided with sample discharging opening; Column casing lateral wall is provided with into homogenate ball valve and goes out homogenate ball valve, and on average connect three oil cylinders and three supporting legs by bolt, crossbeam is fixed with respectively above three oil cylinders, be fixedly connected sequentially below crossbeam nut and piston brace rod, piston brace rod is fixed through connecting rod fairlead, upper end cover and piston successively, is provided with sample feed port above piston.
Active force acts on piston by crossbeam, attaching nut and piston brace rod by oil cylinder successively, and piston is moved up and down in column casing.Regulate into homogenate ball valve, go out homogenate ball valve, water inlet ball valve and delivery port ball valve, by water inlet ball valve, water is injected above piston, after water is full of the epicoele of piston, move under can making piston in column casing.
Advantage of the present utility model is: (1) hydraulic pressure structural design makes piston upper and lower surface area approximation in equal, and the pressure in column casing is approximately equal to the pressure (i.e. water inlet hydraulic pressure size) of piston upper chamber, reduces the loss relating to parts, adds service life; (2) three cylinder forces are even, and piston up-down is more steady; (3) oil cylinder is placed in the both sides of column casing, and compared with being placed in above column casing with oil cylinder in conventional structure, the height of complete equipment reduces, and reduces the instructions for use of factory building height.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Fig. 2 is overall appearance figure of the present utility model
In figure, concrete code name is as follows: 1, column casing 2, oil cylinder 3, crossbeam 4, sample feed port 5, attaching nut 6, piston brace rod 7, connecting rod fairlead 8, upper end cover 9, piston thrust ring 10, piston 11, enter homogenate ball valve 12, go out homogenate ball valve 13, bottom end cover 14, sample discharging opening 15, supporting leg 16, safety valve 17, water inlet ball valve 18, Pressure gauge 19, delivery port ball valve.
Detailed description of the invention
Composition graphs 1 and Fig. 2 are described in further detail the utility model.
Prepare before work: regulation safety valve 16 to setting pressure, piston 10 moves upward, make it contact with piston thrust ring 9, open sample feed port 4, enter homogenate ball valve 11, go out homogenate ball valve 12, water inlet ball valve 17 and delivery port ball valve 19, close sample discharging opening 14.
Dress post: homogenate is thrown in column casing 1 from entering homogenate ball valve 11 with pump, when meeting the requirements of volume (if to column casing maximum height, can from go out homogenate ball valve 12 observe homogenate whether overflow determine), close into homogenate ball valve 11 and go out homogenate ball valve 12.
Pressurize: this step is divided into two parts, one is that oil cylinder 2 makes piston 10 move downward, and two is that hydraulic pressure structure makes piston 10 move downward.Start oil cylinder 2, make its active force successively by crossbeam 3, attaching nut 5 and piston brace rod 6 act on piston 10, piston 10 is driven to move downward along column casing 1, observe sample feed port 4 to occur with or without homogenate, if have, stop oil cylinder 2, open sample discharging opening 14, with pump, water is injected in column casing 1 from water inlet ball valve 17, observe delivery port ball valve 19, (illustrate that in piston upper chamber, air is discharged) when having water to overflow, close delivery port ball valve 19, continue to water filling in column casing 1, solvent now in homogenate is slowly discharged by sample feed port 4 and sample discharging opening 14, observe the change of Pressure gauge 18 registration on upper end cover 8, after meeting the requirements of pressure, pressure column casing 1 being carried out to a period of time maintains, close water inlet ball valve 17.
Loading: sample enters column casing by sample feed port 4, through being uniformly distributed of piston 10, flowing into post bed and carries out chromatographic isolation, after bottom end cover 13 flows out, complete the separation of sample.
Unload post: after the chromatrographic separation step of sample completes, slowly open delivery port ball valve 19, make the pressure in column casing 1 progressively reduce to zero, remove bottom end cover 13, decline oil cylinder 2, piston 10 is moved downward, discharges the filler in column casing 1, open into homogenate ball valve 11, close delivery port ball valve 19, lifting oil cylinder 2, makes piston 10 move upward, and discharges the water of hydraulic pressure in column casing 1.
