Description
Technical field
A kind of sealing structure is the utility model is related to, especially a kind of extraction equipment sealing structure, specifically one
Kind Novel supercritical extraction equipment quick seal coupling.
Background technology
Extraction equipment is supercritical CO2Key equipment in fluid extraction system, generally has the characteristics that：（1）It is some
The solid material of comminution pretreatment, such as some natural prodcuts that fibre structure must be kept not change should not be carried out, are needed
The top cover charging and discharging of extraction equipment are opened, therefore supercritical fluid extraction is mostly semi-batch operation（It is extracted material one
Secondary property loads, supercritical CO2Fluid is continuously passed through, and the material in extraction kettle needs frequently to change, and extraction equipment must have fast
The characteristics of speed switch.（2）CO2Critical pressure be 7.3MPa, but in order to which extracting substances are come out, generally require higher behaviour
Make pressure, therefore the design pressure of supercritical fluid extraction equipment is typically in more than 30MPa.The operating pressure of equipment is high, extraction
The design and production difficulty of equipment are larger.（3）The domestic research and development to supercritical fluid extraction equipment is still in primary rank
Section, lacks experience and effective design method, temporarily the design standard without supercritical fluid extraction equipment, therefore supercritical fluid extracts
Taking equipment is mostly non-standard equipment, and design and manufacture have very big uncertainty.（4）Extraction equipment is grasped under high pressure
Make, it is necessary to often switch, equipment within a production cycle pressure with being fluctuated above and below the time, therefore extraction equipment exist it is tired
Labor problem.（5）Supercritical fluid has strong solubility and high osmosis, and the destruction to the encapsulant of equipment is very serious.Therefore
The encapsulant and structure of extraction equipment must adapt to supercritical fluid this characteristic.Therefore, new fast sealing is designed to connect
Head is a critical component in whole device.
Utility model content
The purpose of this utility model is to be directed to the problem of existing supercritical extracting equipment joint is inconvenient for use, and design is a kind of
Novel supercritical extraction equipment quick seal coupling.
The technical solution of the utility model is：
A kind of Novel supercritical extraction equipment quick seal coupling, it includes top cover 1, cylinder 5, clip 2 and sealing ring
4, top cover 1 is connected with cylinder 5 by clip 5, it is characterized in that described sealing ring 4 is positioned in the annular groove of top cover 1 and energy
With the synchronous dismounting of top cover 1, annular protrusion 8 is provided with the surface of top cover 1 and cylinder 5, clip 5 is provided with the annular groove to match,
Described annular protrusion 8 and annular groove can limit the axial movement of top cover and cylinder.
Supporting plate 7 is installed, clip 2 is bivalve structure, and phase is hinged by straight pin 6 between two valves on described cylinder
Even, it is mobile to limit the circumference of clip 2 in the pin-and-hole in the lower end insertion supporting plate 7 of straight pin 6.
Described sealing ring 4 is C-shaped sealing ring.
Described sealing ring 4 is polytetrafluoroethylmaterial material product.
The trapezoidal structure in section of described annular protrusion 8.
The beneficial effects of the utility model：
1）Encapsulant has abandoned traditional elastomeric material, using polytetrafluoroethylmaterial material, on the one hand ensure that sealing material
The sealing property of material under high pressure, has on the other hand prevented traditional elastomeric material high swelling phenomenon under supercritical fluid CO 2.
2）C-shaped is sealed into ring design in top cover, sealing ring is taken out with top cover when opening extraction kettle, sealing ring
Disposably load, without multiple assembly and disassembly, reduce abrasion when assembly and disassembly number and sealing ring handling, it is easy to operate, extend
The service life of sealing ring.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1.
A kind of Novel supercritical extraction equipment quick seal coupling, it includes top cover 1, cylinder 5, clip 2 and sealing ring
4, top cover 1 is connected described sealing ring 4 using polytetrafluoroethylmaterial material preparation with cylinder 5 by clip 5, and C-shaped in configuration, it is straight
Placement positioning is connect in the annular groove of top cover 1 and can be dismantled with top cover 1 is synchronous, annular is provided with the surface of top cover 1 and cylinder 5
Projection 8, the trapezoidal structure in section of the annular protrusion 8, such as Fig. 1, clip 5 are provided with the annular groove to match, described annular
Projection 8 and annular groove can limit the axial movement of top cover and cylinder.Supporting plate 7 is installed, clip 2 is double on described cylinder
Valve structure, it is hinged and connected by straight pin 6 between two valves, is blocked in the pin-and-hole in the lower end insertion supporting plate 7 of straight pin 6 with limit
The circumference of hoop 2 is mobile.
The utility model is not directed to partly same as the prior art or can realized using prior art.
