Abstract
The invention discloses a kind of chromatographic column seal assemblies, include: sequentially coaxially be arranged from top to bottom screw ring, support ring and sealing ring, wherein, it is described to screw elastic connection between ring and support ring, the support ring and sealing ring are made of ferrimagnet, are coaxially provided with annular permanent magnet between the support ring and sealing ring.According to the present invention, have disassembly, cleaning, assembly simple, sealing effect is good, can substantially reduce chromatographic column in docking injection process by the beneficial effect of the probability of secondary pollution.
Description
Technical field
The present invention relates to a kind of seal assembly, in particular to a kind of chromatographic column seal assembly.
Background technique
Chromatographic technique is in the advantage in separating and filtering field it is well known that can be used for from COMPLEX MIXED solution effectively
Target product is isolated, the impurity in object is removed, purifies final product or replacement product solution etc., chromatographic technique has
The characteristics of high separating efficiency, can separate the product of temperature-sensitive or easy in inactivation, such as protein, polysaccharide under conditions of condition is relatively mild
With polypeptide etc..Chromatographic column is the key that realize chromatography, and chromatographic column is generally by cylindric shell, the circle being sheathed in shell
Tubular splitter, the inlet for injecting solution to be separated, for export separation after solution outflux.
During toward liquid to be purified is injected inside chromatographic column, the sealing of chromatographic column inlet is particularly important, tradition
The upper Butt sealing component for chromatographic column is inconvenient in disassembly, cleaning and installation, and disassembly or assembling process are cumbersome, sealing
Effect is also undesirable.In view of this, it is really necessary to develop a kind of Butt sealing structure for chromatographic column, to solve above-mentioned ask
Topic.
Summary of the invention
Shortcoming present in view of the above technology, the object of the present invention is to provide a kind of chromatographic column seal assembly,
Disassembly, cleaning, assembly are simple, and sealing effect is good, can substantially reduce chromatographic column in docking injection process by secondary pollution
Probability.
In order to realize above-mentioned purpose according to the present invention and other advantages, a kind of chromatographic column seal assembly is provided, comprising:
What is be sequentially coaxially arranged from top to bottom screws ring, support ring and sealing ring,
Wherein, described to screw elastic connection between ring and support ring, the support ring and sealing ring are by ferrimagnet system
At being coaxially provided with annular permanent magnet between the support ring and sealing ring.
Preferably, described to screw the spring that several equidistantly distributeds are equipped between ring and support ring.
Preferably, ring and the support ring of screwing passes through at least three bolts realization detachable connection.
Preferably, the side wall for screwing ring is equipped at least three mounting holes for running through its side wall.
Preferably, the outer wall for screwing ring and chromatographic column inlet is connected through a screw thread.
Preferably, sealing ring is coaxially socketed on the sealing ring.
Preferably, the sealing ring is made of elastic material.
Preferably, the hardness of the sealing ring is 40~60A.
Compared with prior art, the present invention the beneficial effect is that: it is dismantled, cleaning, assembles simply, and sealing effect is good, energy
Chromatographic column is enough substantially reduced in docking injection process by the probability of secondary pollution.
Detailed description of the invention
Fig. 1 is according to chromatographic column seal assembly explosive view of the present invention；
Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings, foregoing end other objects of the invention, feature, side
Face and advantage will be apparent, and so that those skilled in the art can carry out according to the description.
Referring to Fig. 1, chromatographic column seal assembly 100 includes:
It is sequentially coaxially socketed on chromatographic column inlet from top to bottom and screws ring 130, support ring 120 and sealing ring
110,
Wherein, elastic connection between ring 130 and support ring 120 is screwed, support ring 120 and sealing ring 110 are by ferromagnetism material
Material is made, and annular permanent magnet 112 is coaxially provided between support ring 120 and sealing ring 110.Support can be thus achieved in permanent magnet 112
The quick connection of ring 120 and sealing ring 110 is also able to achieve the fast quick-detach of the two.
In a preferred embodiment, the spring that several equidistantly distributeds are equipped between ring 130 and support ring 120 is screwed
140。
Referring to Fig. 1, the detachable company that ring 130 and support ring 120 realize the two by least three bolts 133 is screwed
It connects.In a preferred embodiment, bolt 133 is equidistantly equipped with 3.
Referring to Fig. 1, the side wall for screwing ring 130 is equipped at least three mounting holes 132 for running through its side wall, screws ring and layer
The outer wall of analysis column inlet is connected through a screw thread.It can be by screwing in installation bolt, screwing after screwing in mounting hole 132
Ring 130 is further fastened with chromatographic column inlet.
In a preferred embodiment, sealing ring 113 is coaxially socketed on sealing ring 110, sealing ring 113 is by elastic material
It is made.In one embodiment, the hardness of sealing ring 113 is 40~60A.Sealing ring 113 can be further improved seal assembly
100 leakproofness.
Number of devices and treatment scale described herein are for simplifying explanation of the invention.To application of the invention,
Modifications and variations will be readily apparent to persons skilled in the art.
Although the embodiments of the present invention have been disclosed as above, but it is not limited in listed fortune in specification and embodiments
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily real
Now other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is not limited to
Specific details and legend shown and described herein.
