Description

Technical Field

[0001] This utility model relates to the field of aromatic oil extraction technology, specifically to an aromatic oil-water separation device. Background Technology

[0002] Aromatic oils, also known as plant essential oils, are essential oils made by extracting and refining the fragrant molecules secreted by plant cells. In the fragrance industry, they are simply called essential oils. Aromatic oils are products of plant metabolism. They are secreted by the protoplasts of cells, are mostly volatile, and have an aromatic odor. Extraction methods for aromatic oils include distillation, pressing, and extraction. Because aromatic oils are volatile, heating flowers and leaves containing aromatic oils in water allows the steam to carry away the more volatile aromatic oils, forming an oil-water mixture. After cooling, the mixture separates back into oil and water layers. Removing the water layer yields the aromatic oil; this extraction method is called distillation.

[0003] Utility model patent CN206570298U discloses a plant distillation essential oil recovery device, including an extraction tank, a condenser, and a cooler connected in sequence, and an oil-water separator. The oil-water separator includes a separation container, an oil collection cup, and an oil pipe. The oil collection cup is connected to the oil pipe, and the separation container is connected to the oil collection cup. The oil-water separator also includes an overflow pipe with a control valve. The separation container is connected to the overflow pipe. It also includes a buffer container. The cooler outlet is connected to the buffer container inlet, and the buffer container outlet is connected to the oil-water separator inlet. The buffer container outlet is higher than the buffer container inlet.

[0004] While the aforementioned patent enables the extraction of aromatic oils, several issues remain during its use: the buffer container is equipped with a breather, which, being open to the atmosphere, inevitably allows oil vapors to escape, causing essential oil evaporation and waste. Furthermore, the liquid level in the separation container fluctuates significantly, necessitating frequent liquid and oil control operations. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an aromatic oil-water separation device to improve the extraction efficiency of aromatic oil.

[0006] The technical solution adopted by this utility model to solve its technical problem is an aromatic oil-water separation device, including an oil-water separator. The top of the oil-water separator is provided with a flow pipe communicating with a condenser. The bottom of the oil-water separator is provided with a water outlet pipe, and a first valve is provided on the water outlet pipe. The top of the oil-water separator is provided with an evaporation pipe, which communicates with the outlet of a distillation device. The device is characterized in that: an oil outlet pipe is provided on the side wall of the oil-water separator, which communicates with the top of the oil-water separator and an oil collection glass, and a second valve is provided on the oil outlet pipe; an oil drain pipe is provided at the bottom of the oil collection glass, and a third valve is provided on the oil drain pipe; a reflux pipe is inclined upwards on the side wall of the oil-water separator, which communicates with the oil-water separator and the evaporation pipe, and a fourth valve is provided on the reflux pipe; the height of the connection between the oil outlet pipe and the oil-water separator is lower than the height of the connection between the reflux pipe and the evaporation pipe, but higher than the height of the connection between the reflux pipe and the oil-water separator.

[0007] Furthermore, the oil-water separator is vertically provided with an observation hole, which is covered with a transparent plate.

[0008] Furthermore, a return water pipe is provided on the oil drain pipe between the third valve and the oil collecting glass cup. One end of the return water pipe is connected to the oil drain pipe, and the other end is connected to the evaporation pipe. A fifth valve is provided on the return water pipe.

[0009] Furthermore, the first valve, the second valve, the third valve, the fourth valve, and the fifth valve are all ball valves.

[0010] Furthermore, the angle between the axis of the reflux pipe and the axis of the oil-water separator is 52°.

[0011] The beneficial effects of this invention are as follows: Through the coordinated control of the first and fourth valves, precise discharge of the water layer within the oil-water separator is achieved. The height of the connection between the oil outlet pipe and the oil-water separator is lower than the height of the connection between the return pipe and the evaporator pipe, but higher than the height of the connection between the return pipe and the oil-water separator. This parameter combination maintains a dynamic balance in the liquid level of the oil-water separator. The return pipe is connected to the evaporator pipe at a 52° angle, and in conjunction with the intermittent opening and closing of the fourth valve, a pulse-like return flow is formed, achieving internal pressure regulation within the oil-water separator and preventing waste of essential oil.

Detailed Implementation

[0014] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0015] like Figure 1 As shown, this utility model discloses an aromatic oil-water separation device, comprising an oil-water separator 1, a flow pipe 3 connected to a condenser 2 at the top of the oil-water separator 1, a water outlet pipe 4 at the bottom of the oil-water separator 1, a first valve 5 on the water outlet pipe 4, and an evaporation pipe 6 at the top of the oil-water separator 1, which is connected to the outlet of a distillation device 7; characterized in that: an oil outlet pipe 8 is provided on the side wall of the oil-water separator 1, which connects the top of the oil-water separator 1 and the top of an oil collection glass cup 9. A second valve 10 is provided on the oil outlet pipe 8; an oil drain pipe 11 is provided at the bottom of the oil collecting glass cup 9, and a third valve 12 is provided on the oil drain pipe 11; a return pipe 13 is provided at an upward inclination on the side wall of the oil-water separator 1, the return pipe 13 connects the oil-water separator 1 and the evaporator pipe 6, and a fourth valve 14 is provided on the return pipe 13; the height of the connection between the oil outlet pipe 8 and the oil-water separator 1 is lower than the height of the connection between the return pipe 13 and the evaporator pipe 6, but higher than the height of the connection between the return pipe 13 and the oil-water separator 1.

[0016] The oil-water separator 1 is a long cylindrical, vertically arranged structure. The condenser 2 condenses the oil-water mixture in the evaporator tube 6 into a liquid state. The water outlet pipe 4 is located at the bottom of the oil-water separator 1 and connects to its inner cavity. Opening the first valve 5 allows water to be discharged from the oil-water separator 1. The evaporator tube 6 allows the oil-water mixture to pass through. After entering the oil-water separator 1, the mixture rises and enters the condenser 2. Cooled by the condenser 2, the mixture falls back into the oil-water separator 1. Because oil is less dense than water and they are immiscible, the oil floats on the surface of the water, forming a stratification in the oil-water separator 1. The oil outlet pipe 8 discharges the oil from the oil-water separator 1 into the oil collection glass cup 9. The second valve 10 controls the opening and closing of the oil outlet pipe 8. An oil drain pipe 11 is located at the bottom of the oil collection glass cup 9, used to drain the oil from the oil collection glass cup 9. The oil inside is discharged, and the third valve 12 opens or closes the oil drain pipe 11. The height of the connection between the oil outlet pipe 8 and the oil-water separator 1 is lower than the height of the connection between the return pipe 13 and the evaporator pipe 6, but higher than the height of the connection between the return pipe 13 and the oil-water separator 1. With this setting, as the liquid level in the oil-water separator 1 rises, when the liquid level rises to the connection between the oil outlet pipe 8 and the oil-water separator 1, the oil can enter the oil collection glass cup 9 through the oil outlet pipe 8, and then be discharged through the oil drain pipe 11. When the liquid level in the oil-water separator 1 rises to the height of the connection between the return pipe 13 and the evaporator pipe 6, the fourth valve 14 is opened, and the liquid in the oil-water separator 1 will enter the evaporator pipe 6 through the return pipe 13, achieving liquid level balance in the oil-water separator 1. If the water level in the oil-water separator 1 is higher than the connection between the oil outlet pipe 8 and the oil-water separator 1, the water outlet pipe 4 can be opened to drain the water.

[0017] In order to monitor the liquid level inside the oil-water separator 1 in real time, an observation hole 15 is vertically provided on the oil-water separator 1, and a transparent plate 16 is covered on the observation hole 15.

[0018] During the process of draining oil from the oil-water separator 1 through the oil outlet pipe 8 to the oil collection glass cup 9, if the water level in the oil-water separator 1 is higher than the connection between the oil outlet pipe 8 and the oil-water separator 1, water from the oil-water separator 1 will enter the oil collection glass cup 9. Furthermore, a return water pipe 17 is installed on the oil drain pipe 11 between the third valve 12 and the oil collection glass cup 9. One end of the return water pipe 17 is connected to the oil drain pipe 11, and the other end is connected to the evaporation pipe 6. A fifth valve 18 is installed on the return water pipe 17. Secondary oil-water separation can be achieved in the oil collection glass cup 9. A very small amount of water is located at the bottom of the oil collection glass cup 9. By closing the fourth valve 14 and opening the fifth valve 18, the water can flow back into the distillation apparatus 7.

[0019] Furthermore, the first valve 5, the second valve 10, the third valve 12, the fourth valve 14, and the fifth valve 18 are all ball valves.

[0020] Furthermore, the angle between the axis of the return pipe 13 and the axis of the oil-water separator 1 is 52°.

[0021] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
