Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0024] Please refer to Figures 1 - 3 , the present application provides an essential oil extraction oil-water separator, including an evaporation tank 10. A packing 20 is arranged at the upper part of the evaporation tank 10, a tray 30 is arranged at the upper end of the packing 20, an ultrasonic oscillator 40 is arranged at the lower part of the evaporation tank 10, a cooling mechanism 50 is arranged outside the oscillator 40, and a condensation mechanism 60 is communicated above the evaporation tank 10. Among them, an ultrasonic oscillator 40 is arranged in the evaporation tank 10 to achieve a cell wall breaking effect on the internal plant raw materials, so as to increase the yield of essential oil extraction. By using the settings of the tray 30 and the packing 20, the gas-liquid exchange is increased, and at the same time, the steam temperature and pressure are increased, so as to improve the purity and yield of the essential oil. The cooling mechanism 50 is used to cool the oscillator 40 to ensure the normal operation of the oscillator 40.

[0025] Please refer to Figures 1 - 3 , the evaporation tank 10 is in a gourd shape. The gourd-shaped space makes the path of the steam longer during the rising process, thereby increasing the contact time between the steam and the liquid on the tray 30 and the packing 20. The longer contact time helps for more sufficient gas-liquid exchange and improves the separation and purification effect.

[0026] Please refer to Figures 1 - 3 , the condensation mechanism 60 includes a condensation pipe 61 and a cooling tank 62. The condensation pipe 61 is fixedly penetrated through the cooling tank 62, and cooling water flows in the cooling tank 62. The condensation pipe 61 in the cooling tank 62 is spiral-shaped. The steam enters the cooling tank 62 through the condensation pipe 61, is cooled by the cooling water and condenses on the inner wall of the condensation pipe 61 and then drops. The spiral-shaped condensation pipe 61 can increase the time of the steam in the cooling tank 62 and improve the condensation effect.

[0027] Please refer to Figures 1 - 3 , the cooling tank 62 is provided with a water inlet pipe 63 and a water outlet pipe 64. The water inlet pipe 63 and the water outlet pipe 64 are used to connect to external cooling water to provide a continuous cooling water circulation for the cooling tank 62.

[0028] Please refer to Figures 1 - 3, a liquid storage tank 65 is provided below the cooling tank 62, a drain port 66 is provided below the liquid storage tank 65, and an oil pumping port 67 is provided above the liquid storage tank 65. The condensed liquid accumulates in the liquid storage tank 65. The essential oil floating on the upper layer is pumped away through the oil pumping port 67, and the water in the lower layer is discharged through the drain port 66.

[0029] Please refer to Figures 1 - 3 , the cooling mechanism 50 includes a C-shaped pipe cover 51. The pipe cover 51 covers the tails of all the vibrators 40, and cooling water flows through the pipe cover 51. A connecting pipe 52 is provided at the water outlet of the pipe cover 51 and is communicated with the water inlet pipe 63 on the cooling tank 62. The external cooling water supply device first injects the cooling water into the pipe cover 51 to cool the vibrators 40. The cooling water flows through each vibrator 40 and then flows into the cooling tank 62 through the connecting pipe 52 for condensation, which can improve the utilization rate of the cooling water.

[0030] The working principle of this essential oil extraction oil-water separator is as follows: The plant raw materials are put into the evaporation tank 10. The evaporation tank 10 heats and evaporates the raw material liquid inside. At the same time, the vibrator 40 makes the raw material liquid generate ultrasonic vibration to achieve the cell wall breaking effect, so as to increase the essential oil extraction rate. The steam enters the cooling tank 62 through the condensation pipe 61 and condenses into a mixed liquid here. The mixed liquid flows into the lower liquid storage tank 65. The essential oil floating on the upper layer is pumped away through the oil pumping port 67, and the water in the lower layer is discharged through the drain port 66. The external cooling water supply device first injects the cooling water into the pipe cover 51 to cool the vibrators 40. The cooling water flows through each vibrator 40 and then flows into the cooling tank 62 through the connecting pipe 52 for condensation. In this way, the vibrators 40 can be cooled to adapt to the high temperature of the evaporation tank 10, and then the normal operating temperature can be ensured. It can also improve the utilization rate of the cooling water. In summary, ultrasonic vibrators 40 are arranged in the evaporation tank 10 to achieve the cell wall breaking effect on the internal plant raw materials, so as to increase the essential oil extraction rate. By using the settings of the tray 30 and the packing 20, the gas-liquid exchange is increased, and at the same time, the steam temperature and pressure are increased, so that the essential oil purity and extraction rate are improved. The cooling mechanism 50 is used to cool the vibrators 40 to ensure the normal operation of the vibrators 40.
