Extraction tube multi-fulcrum butt joint ring for supercritical extraction equipment

Abstract

The invention relates to the technical field of supercritical extraction, in particular to an extraction tube multi-fulcrum butt joint ring for supercritical extraction equipment, which comprises two extraction tubes, flange plates are fixedly connected to opposite ends of the two extraction tubes, and arc-shaped connecting blocks symmetrically and movably sleeve the exteriors of the two extraction tubes and the flange plates. The device is reasonable in design and ingenious in structure, through mutual cooperation of the structures, the connection tightness and stability between the two extraction pipes can be effectively improved, flexible angle and distance adjustment can be conducted on the multiple supporting plates, and the device is convenient to use and high in practicability. The butt joint ring can meet different installation requirements of the extraction pipe, the butt joint ring can be locked emergently when the bolt is loosened due to too high pre-tightening force, an alarm is given in time, workers are reminded to overhaul the extraction pipe, and the butt joint ring has good market competitiveness and is worthy of recommendation.

Description

technical field [0001] The invention relates to the technical field of supercritical extraction, in particular to an extraction tube multi-fulcrum docking ring for supercritical extraction equipment. Background technique [0002] With the development and progress of society, critical extraction technology is more and more applied to industrial production, and the solvent strength of supercritical fluid depends on the temperature and pressure of extraction. Utilizing this feature, only by changing the pressure and temperature of the extractant fluid, the different components in the sample can be extracted successively according to the solubility in the fluid, and the weakly polar substances are extracted first under low pressure, and as As the pressure increases, the polar and large molecular weight substances and their basic properties, so supercritical extraction under programmed pressure increase can obtain different extraction components, and at the same time, it can also...

AI Technical Summary

Problems solved by technology

[0003] The existing extraction tube butt joint structure generally adopts a flange butt joint structure, which not only has poor connection stability and sealing performance, but also in this structure, the pipeline pressure acts on the butt flange end face, and the ultimate pressure reaches 5Mpa. When the bolts on the flange surface have an excessively high bolt pre-tightening force, the bolts will break. Therefore, when this docking structure is used, regular maintenance is required, which is inconvenient to use. In addition, in order to facilitate the support and fixation of the extraction tube, People often set fulcrums outside the docking structure, but most of the existing fulcrums are fixed, which is not easy to adjust according to the different installation environments of the extraction tube, and has certain limitations in use
