Abstract

This invention provides a peony essential oil extraction and filtration device, relating to the field of plant essential oil extraction technology. It includes a stirring assembly, a conveying assembly, a multi-stage filtration unit, and a moving assembly connected in sequence. The stirring assembly includes a motor, a stirring shaft, primary stirring blades, and secondary stirring blades. The bottom output shaft of the motor is driven and connected to the stirring shaft, and the primary and secondary stirring blades are fixedly connected to the stirring shaft from top to bottom. The conveying assembly includes a diaphragm pump. The inlet of the diaphragm pump is connected to the outlet of the stirring assembly, and the outlet of the diaphragm pump is connected to the multi-stage filtration unit. This invention integrates stirring, extraction, conveying, and filtration functions into one unit, eliminating the need for manual material transfer, reducing the risk of essential oil volatilization and contamination, and improving production efficiency. The diaphragm pump prevents solid impurities from clogging the solution, and the fluororubber diaphragm is resistant to organic solvents and causes no secondary pollution, making it suitable for conveying essential oil mixtures containing impurities.
