Description

Technical Field

[0001] This utility model belongs to the field of extraction equipment technology, and in particular relates to an extraction device for the purification of vinyl ether. Background Technology

[0002] Extraction equipment, also known as an extractor, is a type of mass transfer device used for liquid-liquid or solid-liquid extraction operations. It achieves component separation by promoting contact between two phases and is mainly used in chemical, petroleum, nuclear, and environmental protection fields. Its working principle is based on the difference in the distribution of substances between two phases, and separation is completed through the mass transfer of dispersed phase droplets. According to its structure, it can be divided into three categories: mixing clarifiers, extraction towers, and centrifugal extractors.

[0003] Chinese patent CN222765716U discloses an extraction device for the refining of vinyl ether. The device includes a support rod and a glass spherical vessel. The support rod includes a sliding rod and a base plate. A display panel is mounted on the upper end of the support rod. The sliding rod slides through the interiors of a first connecting plate and a second connecting plate. A stirring motor is mounted on the upper side of the first connecting plate, and a connecting rod is fixed to the output shaft of the stirring motor. A glass spherical vessel is located on the lower side of the connecting rod, and a fixing pipe is fixed to the upper side of the glass spherical vessel. The fixed tube is movably connected to the stirring rod via a bearing... In this extraction equipment for the refining of vinyl ethyl ether, rotating the double-ended screw causes the first and second connecting plates to move away from each other, allowing the operator to quickly remove the glass ball vessel. The glass ball vessel is then placed on the upper side of the connecting ring plate. Rotating the double-ended screw in the opposite direction allows the connecting block to fully enter the docking groove, enabling the stirring rod to perform normal stirring operations. This facilitates the disassembly or installation of the glass ball vessel in the extraction equipment. Rotating the knob allows the two support plates to be moved out from inside the support of the upright base, which enhances the stability of the extraction equipment.

[0004] However, the above-mentioned solutions require manual operation for disassembly and assembly. Vinyl ether itself is toxic, and there is a certain risk if leakage occurs during manual operation. Furthermore, there is a lack of detection and automatic disassembly / assembly of the extraction equipment. Therefore, it is necessary to design an extraction device for the purification of vinyl ether. Utility Model Content
