Description
Technical field
The utility model relates to a kind of blender, particularly a kind of chromatograph high pressure static mixer.
Background technology
The chromatograph static mixer is a kind of device that two or more different solvents that high pressure constant flow pump is transported mixes.For guaranteeing the constant pressure in a whole set of chromatograph system, static mixer must tolerate certain high pressure (being generally 40MPa).In the application of reality, except requiring that the multiple solvent of input is had mixed effect preferably; Also having the internal mixer volume can not be excessive; The dead angle that not remaining solvent can't be discharged in the cavity; Requirements such as the organic solvent that is introduced into discharge as far as possible earlier.
At present, chromatograph mainly contains following three kinds with static mixer structure commonly used, all exists the not problem of degree.
One, coiled static mixer: the different organic solvent of two-way is pooled to the thinner stainless steel tube porch of internal diameter by threeway, and liquid produces diffusion in the process of pipeline of flowing through, thereby reaches the effect of mixing.Because what adopt is the nature diffusion principle, this kind static mixer can't obtain mixed effect preferably.
Two, ball-type static mixer: the ball that particle diameter is identical is filled in the tubular housing inside of sealing.In liquid is flowed through the process of tubular housing, owing to be subjected to the obstruction of ball, can only between peripheral slit, disperse, finally merge in the exit.The problem of this kind static mixer maximum is long in the holdup time of liquid in cavity, thereby can't realize " first in first out " of different solvents.
Three, multistage diaphragm type static mixer: the static mixer of this kind structure is that the stainless steel diaphragm of many identical appearance sizes is placed in the middle of the stream according to certain Cahn-Ingold-Prelog sequence rule.Liquid flow direction when impacting steel disc changes, thereby forms local little eddy current, finally reaches the effect of mixing.Because the difficulty of machining, welding, assembling is bigger, finished product is on the high side and yield rate is lower.Be subjected to structural limitations, can't adjust the internal mixer volume.
In sum, need a kind of novel static mixer that can address the above problem now.
Summary of the invention
The utility model is in order to solve the above-mentioned deficiency of existing in prior technology, proposes a kind of simple in structurely, designs ingenious, low-cost, high withstand voltage, small size, chromatograph high pressure static mixer that versatility is good.
Technical solution of the present utility model is: a kind of chromatograph high pressure static mixer, it is characterized in that: described blender comprises blender joint 1, side at blender joint 1 is provided with loam cake 3 and the lower cover 4 that connects as one structure by sealing bolt 2, between loam cake 3 and lower cover 4, be folded with sealing gasket 5, between loam cake 3 and lower cover 4, be provided with the hybrid chamber unit, described hybrid chamber unit is by column mixing chamber 6, the last connecting bolt 7 that matches, upper pipeline 8, the following connecting bolt 9 that matches, lower pipeline 10 is formed, column mixing chamber 6 is arranged between loam cake 3 and the lower cover 4, be provided with hollow last connecting bolt 7 in the loam cake 3, cross-under has upper pipeline 8 in the last connecting bolt 7, upper pipeline 8 is connected with the upper end of column mixing chamber 6, the lower end of column mixing chamber 6 is communicated with the initial end of upper pipeline 8 with the lower pipeline 10 that is connected in the lower cover 4 by following connecting bolt 9, the end of lower pipeline 10 all links to each other with blender joint 1.
Described hybrid chamber unit is a plurality of, equidistantly is axially disposed within on loam cake 3 and the lower cover 4.
Described sealing bolt 2 is a plurality of, and axially is arranged on symmetrically on loam cake 3 and the lower cover 4.
Described sealing gasket 5 is provided with positioning pin column 11, and loam cake 3 is provided with the locating hole that matches with positioning pin column 11.
The utility model is compared with prior art, has following advantage:
The chromatograph of this kind of version high pressure static mixer adopts two-piece type, multi-cavity body structure, and under the precondition that does not influence mixed effect, mixed structure is simple relatively, thereby has reduced processing and assembling difficulty; The characteristics on its little cavity, tubule road have guaranteed minimizing of internal volume; The employing of sealing bolt, sealing gasket guarantees that blender can tolerate high pressure; The connected mode of multi-cavity external body polyphone can be switched mixed volume at the most at one grade between the shelves.Therefore we can say that it has possessed multiple advantage, be particularly suitable for applying in the art that its market prospects are very wide.
