Description

TECHNICAL FIELD

[0001] The utility model relates to an oil liquid separation device, in particular to an oil liquid separation device in essential oil extraction process. BACKGROUND

[0002] When distillation method is used to extract rose essential oil or essential oil of other flowers, petal and water are put into a distillation kettle, water vapor and essential oil are evaporated by heating, then they are cooled into liquid by a condenser, and finally essential oil and water are separated by an oil-water separator. The commonly used oil-water separation device separates the oil and water by the difference in density between the essential oil and water. The essential oil floats on the surface of the water, which is convenient for subsequent unified collection. However, a small amount of essential oil is still mixed in the lower layer of water and does not float on the surface of the water, resulting in insufficient separation of the oil and water and waste of part of the essential oil.

DETAILED DESCRIPTION

[0017] The embodiment of the utility model will be described in detail below, and the embodiment is implemented on the premise of the technical scheme of the utility model, and detailed implementation mode and specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0018] Referring to Figure 1 and Figure 2The embodiment discloses an oil liquid separation device in an essential oil extraction process, which comprises a storage tank 1, and a transparent observation window 2 is arranged on the side wall of the storage tank 1. An input pipe 7 is arranged on one side of the upper section of the storage tank 1, the input pipe 7 is provided with a first check valve near the storage tank 1, a liquid discharge pipe 3 is arranged at the bottom of the storage tank 1, and an opening and closing valve 4 is arranged on the liquid discharge pipe 3. The material is transported into the storage tank 1 through the input pipe 7, and the material in the storage tank 1 is discharged through the liquid discharge pipe 3.

[0019] An air inlet is arranged on the lower section of the storage tank 1, the air inlet is connected with an air pump 6 through an air inlet pipe 5, the air inlet pipe 5 is provided with a second check valve near the storage tank 1, the air pump 6 inputs gas into the storage tank 1 through the air inlet pipe 5, and in actual use, the air inlet end of the air pump 6 can be provided with an air purification device, so that impurities in the transported gas can be removed, and the quality of the essential oil is avoided to be affected. A communication pipe 8 is arranged at the top of the storage tank 1, a transparent overflow cylinder 9 is arranged at the top of the communication pipe 8, the bottom end of the overflow cylinder 9 is open and communicates with the communication pipe 8, the top end of the overflow cylinder 9 is open and connected with an exhaust pipe 11, the upper section of the exhaust pipe 11 is bent downward in an arc shape, the exhaust pipe 11 can discharge the gas in the storage tank 1 to the outside, and the arc shape of the upper section of the exhaust pipe 11 makes it difficult for the external impurities to enter the exhaust pipe 11, so that the essential oil in the overflow cylinder 9 is not affected. The quality of the essential oil is not affected. An overflow pipe 10 is arranged in the inner cavity of the overflow cylinder 9, the upper end of the overflow pipe 10 is lower than the top end of the overflow cylinder 9, the lower end of the overflow pipe 10 is connected with an oil collecting pipe, and the outer end of the oil collecting pipe extends out of the communication pipe 8 to form an oil collecting port. As the water and oil in the storage tank 1 continuously increase, the liquid level and the oil level rise, and the essential oil in the upper layer flows out of the overflow pipe 10 to be collected.

[0020] The overflow cylinder 9 is detachably arranged at the top of the communication pipe 8. The top of the communication pipe 8 is provided with a lower mounting assembly, and the bottom of the exhaust pipe 11 is provided with an upper mounting assembly. The upper mounting assembly and the lower mounting assembly are symmetrically arranged on the upper and lower sides of the overflow cylinder 9. Each mounting assembly comprises a mounting disc 12, and the upper and lower mounting discs 12 are connected by at least two groups of screw nut assemblies. The overflow cylinder 9 is arranged between the upper and lower mounting discs 12, so that the upper and lower ends of the overflow cylinder 9 are connected with the exhaust pipe 11 and the communication pipe 8 respectively. Each group of screw nut assemblies comprises a vertically extending screw rod 13 and two nuts 14. The upper and lower ends of the screw rod 13 pass through the through holes of the upper and lower mounting discs 12 and are screwed with the two nuts 14, so that the overflow cylinder 9 is arranged between the two mounting discs 12, and the upper and lower ends of the overflow cylinder 9 are sealed and connected with the two mounting discs 12 through sealing pads.

[0021] In use, the top end of the input pipe 7 is connected with an externally preset feed pipe, and the inside of the storage tank 1 is previously stored with a certain amount of water, the water level being to the lower half of the overflow cylinder 9 and lower than the top of the overflow pipe 10. The oil-water mixture after high-temperature distillation becomes liquid state after condensation by the condenser pipe, and the liquid-state oil-water mixture enters the inside of the input pipe 7 along the feed pipe and enters the storage tank 1 from the input pipe 7 to mix with the inside water. Since the density of oil is smaller than that of water, the oil moves upward in the water into the overflow cylinder 9 and floats on the water surface, and as the water and oil continuously increase, the liquid level and the oil level both rise, and the upper essential oil flows out from the overflow pipe 10 to be collected. During the oil-water separation process, the water level can be controlled to be always lower than the upper port of the overflow pipe 10, and if the water in the inside of the storage tank 1 is excessive, the on-off valve 4 can be opened to discharge a part of the water outside through the drain pipe 3.

[0022] After the oil-water mixture in the inside of the input pipe 7 enters the inside of the storage tank 1, most of the essential oil moves upward to float on the water surface, and a small part of the essential oil is mixed in the water. The air pump 6 is started to input air into the inside of the storage tank 1 through the air pump 6 and the air inlet pipe 5, the air enters the water to generate a flow disturbance to the water, and the air moves upward from the bottom in the water, which can drive the residual essential oil in the water to move upward and finally float on the water surface, effectively avoiding the case that a small amount of residual essential oil moves downward to cause insufficient oil-water separation. In use, the air inlet amount of the air pump 6 can be freely adjusted to adapt to the needs of different situations. If the residual amount of essential oil is large, the air inlet amount can be correspondingly adjusted.

[0023] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
