Diameter.
Further, the diameter of first sieve plate be less than second female thread at the second internal thread hole hole
Diameter.
Further, the sealing ring is O-shaped rubber ring.
Further, through-hole is offered on the interior pressure cap.
According to the above aspect of the present invention, the utility model at least has the following advantages:
As soon as the utility model adds a dismountable sieve plate among sample introduction end sieve plate and filler, in this way, sieve plate is not
It can directly be contacted with filler, filler would not be lost when removing sieve plate cleaning.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
Art means, and can be implemented in accordance with the contents of the specification, below on the preferred embodiment of the present invention and the accompanying drawings in detail
It describes in detail bright as after.

Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
A kind of dismountable liquid-phase chromatographic column shown in FIG. 1, including external pressure nut 1, interior pressure cap 2, the first sieve plate 3, second
Sieve plate 4, sealing ring 5, cylinder 6 and the filler 7 being filled in cylinder 6 are respectively equipped with the first outer spiral shell on the outer wall of 6 two ends of cylinder
The outer wall of line 8, interior pressure cap 2 is equipped with the second external screw thread 10, and the inner wall of external pressure nut 1 is from top to bottom successively arranged and the first outer spiral shell
Line 8 to the first internal screw thread 9 of adaptation, with 3 outer wall of the first sieve plate compatible smooth inner wall and suitable with 10 phase of the second external screw thread
The second internal screw thread matched, the second sieve plate 4 between cylinder 6 and external pressure nut 1 are the second sieve plate that cross section is convex shape
4, the second sieve plate 4 include for block cylinder 6 opening boss and for the boss seat of fixing lug boss, the diameter of boss is equal to
The internal diameter of cylinder 6, the diameter of boss seat are greater than the internal diameter of cylinder 6 and are less than or equal to the outer diameter of cylinder 6,4 He of the second sieve plate
Sealing ring 5 is arranged between first sieve plate 3.
The principle of dismountable liquid-phase chromatographic column provided by the utility model is as follows:
The first external screw thread 8 is equipped on the outer wall at the both ends of cylinder 6, the outer wall of interior pressure cap 2 is equipped with the second external screw thread 10,
In this way, one end of external pressure nut 1 can be set in the column by first internal screw thread 9 compatible with the first external screw thread 8 fixation
One end of body 6, due to being additionally provided with compatible with the second external screw thread 10 on the interior pressure cap 2 on the inner wall of external pressure nut 1
Two internal screw threads, therefore the other end of external pressure nut 1 can be fixed and be sealed by interior pressure cap 2, the first of 1 inner wall of external pressure nut
Smooth internal diameter between internal screw thread 9 and the second internal screw thread is used to place the first sieve plate 3, and the opening of cylinder 6 passes through the first sieve plate 3
It blocks, making mobile phase that must first pass through the second sieve plate 4 just can enter filler in cylinder 6 and cylinder 6 into crossing the first sieve plate 3 again
7, in this way, can disassemble the second sieve plate 4 when the second sieve plate 4 blocks, ultrasonic cleaning is carried out, and do not have to dynamic
The first sieve plate 3 is often dismantled, keeps the filler 7 in cylinder 6 impaired.
In order to facilitate the sieve pore on more smooth the second sieve plate 4 of process of mobile phase, boss and boss seat integrated moldingization are set
Meter.
It is in order to facilitate progress postsearch screening impurity, the impurity screened out that can pass through detachable first sieve plate 3 is clear in time
It washes, sieve pore is offered on boss and boss seat, the screen-aperture opened up on the first sieve plate 3 is less than or equal to the second sieve
The screen-aperture opened up on plate 4.
The disassembly of first sieve plate 3 for convenience, the diameter of the first sieve plate 3 less than the first internal screw thread 9 formed first in spiral shell
The aperture in 9 hole of line, the diameter of the first sieve plate 3 less than the second female thread at the second internal thread hole aperture.
Leakage occurs when the filler 7 that mobile phase is passed through in cylinder 6 and cylinder 6 in order to prevent, sealing ring 5 is O-shaped rubber ring.
Successively enter in cylinder 6 by interior pressure cap 2, the second sieve plate 4, sealing ring 5, the first sieve plate 3 in order to facilitate mobile phase,
Through-hole 11 is offered on interior pressure cap 2.
Above are merely preferred embodiments of the utility model, it is not intended to limit the utility model, it is noted that for
For those skilled in the art, without deviating from the technical principle of the utility model, if can also make
Dry improvement and modification, these improvements and modifications also should be regarded as the protection scope of the utility model.
