Problems solved by technology

[0002] At present, the supercritical carbon dioxide extraction kettle is sealed with an O-ring (the material is fluororubber). This material will expand when it encounters carbon dioxide (carbon dioxide has a high permeability, and it enters the O-ring under high pressure, and it will expand under the external low pressure environment. O-ring), block the plug, it is not easy to open the kettle body, the operation is inconvenient, and the O-ring is not suitable for reuse after expansion

Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing:

[0015] Such as figure 1 The sealing device of a supercritical carbon dioxide extraction kettle shown includes an upper seal 1, a lower seal 3 and a gasket 2, and an upper seal 1, a lower seal 3 and a gasket 2 are arranged sequentially from top to bottom, and the upper seal Part 1 and lower seal 3 are connected through a card slot; for example figure 2 In the structural diagram of the upper seal shown, the groove angle of the upper seal 1 is 80° and the material is polytetrafluoroethylene; as image 3 As shown in the lower seal structure diagram, the slope angle of the lower seal 3 is 90° and the material is polytetrafluoroethylene; as Figure 4 In the washer structure diagram shown, the material of washer 2 is stainless steel.

[0016] When the present invention is assembled, pressure is applied from the upper and lower ends. Since the slope of the lower seal is 90°...

Abstract

The invention discloses a sealing device of a supercritical carbon dioxide extraction kettle. The sealing device comprises an upper sealing piece, a lower sealing piece and a gasket sequentially from top to bottom. An angle of a groove of the upper sealing piece is 80 degrees, and an angle of a slope of the lower sealing piece is 90 degrees. During assembling, compression force is applied from the upper and the lower ends of the sealing device, and since the angle of the groove of the upper sealing piece is 80 degrees and the angle of the slope of the lower sealing piece is 90 degrees, upper parts can be strutted, and sealing is achieved. By the aid of the sealing device, the extraction kettle is easy to open, and sealing pieces need not to be changed frequently, so that cost is saved, working efficiency is improved, and industrial benefit is increased.

Description

technical field [0001] The invention relates to a sealing device for a supercritical carbon dioxide extraction kettle. Background technique [0002] At present, the supercritical carbon dioxide extraction kettle is sealed with an O-ring (the material is fluororubber). This material will expand when it encounters carbon dioxide (the carbon dioxide has a high permeability, and enters the O-ring under high pressure, and will expand under the external low pressure environment to expand. O-ring), block the plug, it is not easy to open the kettle body, the operation is inconvenient, and the O-ring is not suitable for reuse after expansion. Contents of the invention [0003] Purpose of the invention: the purpose of the invention is to provide a sealing device for a supercritical carbon dioxide extraction kettle in order to solve the deficiencies in the prior art. [0004] Technical solution: A sealing device for a supercritical carbon dioxide extraction kettle according to t...
