Specific embodiment
Illustrate with reference to the accompanying drawing, invention is further described in detail.
As shown in figures 1 to 6, the extraction kettle sealing structure of a kind of supercritical extraction unit, can be used for supercritical extraction unit
In, it specifically may include carbon dioxide storage tank 1, high-pressure pump 2, extraction kettle 3, material barrel fetching device 4, filter 5, divide
From device, product pump 6 and head tank 7；Carbon dioxide storage tank 1 is connected to 3 lower part of extraction kettle by high-pressure pump 2, and high-pressure pump 2 can incite somebody to action
Carbon dioxide in carbon dioxide storage tank 1 is delivered in extraction kettle 3；Head tank 7 is connected to 3 top of extraction kettle, object by product pump 6
Material pump 6 can will be in the feedstock transportation in head tank 7 to extraction kettle 3；Extraction kettle 3 connects separator, separator top connection two
Carbonoxide holding vessel 1；Filter 5 is set between carbon dioxide storage tank 1 and high-pressure pump 2；Material barrel fetching device 4 can fill
Enter or take out the material barrel in extraction kettle 3.
Filter 5 includes filter housings 51 and air inlet 52 and gas outlet 53 positioned at 51 both ends of filter housings,
Air inlet 52 is connected to the gas outlet of carbon dioxide storage tank 1, and gas outlet 53 is connected to the air inlet of 3 bottom of extraction kettle.Filter head housings
Multiple filter assemblies are successively evenly equipped in body 51 along gas flow direction, each filter assemblies include a pair of filtering setting up and down
Roller 54,54 both ends of filter drum can be installed on 51 inner walls of filter by bearing, and 54 surface of filter drum is circumferential
It is evenly equipped with resolution element 55, resolution element 55 is fixedly installed in 54 surface of filter drum, the filter drum in adjacent head component
54 shift to install.It is arranged between 54 surface of resolution element 55 and filter drum in 45° angle.Supercritical carbon dioxide is from mistake as a result,
When passing through in filter, it is able to drive the rotation of filter drum, the biggish filter that reduces is to the resistance of supercritical carbon dioxide.
Wherein, resolution element 55 includes that absorbent charcoal material and active carbon depend on bottom material；Absorbent charcoal material is directly knitted into work
Property charcoal depends in bottom material, reinforces the firmness that depends on of active carbon, in addition, active carbon, which depends on bottom material, can choose 150D high strength yarn,
Active carbon filament is laid in a manner of interval, the additional amount of active carbon filament is that overall activity charcoal depends on the 60~80% of bottom material.Activity
Charcoal, which depends on bottom material, can be designed to wavelike structure, further increase gas and contact area, can effective adsorption seperation of gas
In solid and gaseous impurity.
Wherein, extraction kettle 3 include extraction kettle ontology 31 and be set in turn in 31 upper end of extraction kettle ontology end cap 32,
Plug 33 and sealing ring 34,34 medial surface circumferential direction of sealing ring are integrally formed fluted 35, are provided with elastic component 36 in groove 35.Bullet
Property part 36 be ring structure, cross section be U-shaped structure.As a result, after sealing ring long-time use, the elastic component in groove can
To compensate, prevent to leak, extends the service life of sealing ring, improve leakproofness.
In addition, 3 inner wall of extraction kettle can circumferential direction offer concave ring, 34 outside of sealing ring is circumferential be equipped with cooperate with concave ring it is convex
Ring, bulge loop can be embedded in concave ring, and thus, it is possible to further increase sealing effect.
