Abstract
The utility model discloses a sealing device for a supercritical carbon dioxide extraction kettle. The sealing device comprises an upper sealing element, a lower sealing element and a gasket from top to bottom in sequence; the groove angle of the upper sealing element is 80 degrees; the slope angle of the lower sealing element is 90 degrees; and during assembly, pressure is applied to upper and lower ends, and because the slope of the lower sealing element is 90 degrees and the groove angle of the upper sealing element is 80 degrees, upper parts can be shoved off, and a sealing aim is fulfilled. In the novel sealing mode, the kettle is easily opened, and the sealing elements are not required to be replaced frequently, so that the cost is saved, the work efficiency is improved, and the enterprise benefit is increased.
Description
Technical field
The utility model relates to a kind of seal arrangement for the supercritical carbon dioxide extracting still.
Background technique
The supercritical carbon dioxide extracting still adopts O type circle (material is fluorine rubber) sealing at present, this material is met carbon dioxide (the infiltration rate of carbon dioxide height that can expand, under high pressure conditions, enter O type circle, under extraneous environment under low pressure, can expand, support big O type circle), block plug, be difficult for opening kettle, inconvenient operation, and should not reuse after the expansion of O type circle.
The model utility content
The model utility purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of seal arrangement of supercritical carbon dioxide extracting still to be provided.
Technological scheme: the seal arrangement of a kind of supercritical carbon dioxide extracting still described in the utility model, comprise Sealing, lower seal and packing ring are provided with Sealing, lower seal and packing ring from top to bottom successively, and the described Sealing of going up is connected by draw-in groove with lower seal.
As preferably, the described material of going up Sealing and lower seal is teflon.
As preferably, the material of described packing ring is stainless steel.
As preferably, the described groove angle that goes up Sealing is 80 °.
As preferably, the bevel angle of described lower seal is 90 °.
Beneficial effect: the utility model adopts novel seal form, and kettle is opened easily, need not frequently to change Sealing, thereby has saved cost, has improved working efficiency, has increased the performance of enterprises.
Description of drawings
Fig. 1 is the utility model assembly structure figure.
Fig. 2 is seal configuration figure on the utility model.
Fig. 3 is the utility model lower seal structural drawing.
Fig. 4 is the utility model gasket construction figure.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
The seal arrangement of a kind of supercritical carbon dioxide extracting still as shown in Figure 1 comprises Sealing 1, and lower seal 3 and packing ring 2 are provided with Sealing 1, lower seal 3 and packing ring 2 from top to bottom successively, and last Sealing 1 and lower seal 3 are connected by draw-in groove; Last seal configuration figure as shown in Figure 2, the groove angle of last Sealing 1 is that 80 ° and material are teflon; Lower seal structural drawing as shown in Figure 3, the bevel angle of lower seal 3 are that 90 ° and material are teflon; Gasket construction figure as shown in Figure 4, the material of packing ring 2 are stainless steel.
The utility model is in when assembling, exerts pressure by two ends up and down, because the lower seal inclined-plane is 90 °, the angle of the groove of last Sealing is 80 °, thus can strut upper component, thus reach sealing purpose.
