Description

Technical Field

[0001] The utility model relates to the technical field of plant essential oil processing, in particular to an oil-water separation device for plant essential oil processing. Background Art

[0002] Essential oils are a general term for volatile aromatic substances extracted from aromatic plants or aromatic animals. Essential oils are typically extracted from flowers, leaves, roots, seeds, fruits, bark, resins, and heartwoods of plants through steam distillation, cold pressing, liposorption, or solvent extraction. Rose essential oil, in particular, is known as the "Queen of Essential Oils." It can regulate female endocrine function, nourish the uterus, relieve dysmenorrhea, improve sexual dysfunction and menopausal discomfort, and also has excellent cosmetic and skincare benefits.

[0003] The distillation method for processing essential oils is divided into water distillation, water distillation, and steam distillation. In water distillation, plants (such as rose petals) are placed in clean water or hydrosol distilled from the previous pot, and the essential oil is extracted by heating the water to generate steam; in water distillation, the plants are placed on a sieve plate with clean water below the sieve plate, and steam is generated by heating the clean water, which is then passed through the sieve plate from the plants to extract the essential oil; steam distillation is similar to water distillation, and the plants are also placed on the sieve plate, and the steam generated by the steam generator is directly passed under the sieve plate to extract the essential oil. Regardless of the extraction method, the steam and essential oil mixture needs to be passed into a condensing device, condensed into a liquid, and then the liquid is passed into an oil-water separation device.

[0004] The working principle of the oil-water separation device is very simple. It mainly uses the difference in density between essential oil and water to separate the essential oil. After the mixture of steam and essential oil is condensed into liquid, it is sent to the oil-water separation device to stand. The density of essential oil is small, so it will float on the upper layer. The bottom of the essential oil is the 100% saturated distilled liquid, that is, hydrosol. Therefore, the structure of the existing oil-water separation device is also very simple. It is usually a simple container. A pipe for discharging essential oil is provided at the upper position of the container surface. A pipe for discharging hydrosol is provided at the bottom of the container. A feed port is provided at the top of the container, which is connected to the condensation equipment so that the condensed liquid can directly enter the container. However, the existing oil-water separation device for plant essential oil processing has the following disadvantages when in use:

[0005] 1. The feed port of the oil-water separation device is directly set at the top, so the incoming liquid will fall above the essential oil layer in the oil-water separation device. Therefore, during the separation process, the pure dew needs to pass through the entire essential oil layer before reaching the pure dew layer, so the separation efficiency is slow.

[0006] 2. If a large amount of pure water and essential oil has accumulated in the oil-water separation device during the process of extracting essential oil, it is usually necessary to separate and discharge the pure water and essential oil in the oil-water separation device at the same time. Since the existing oil-water separation device falls on the top of the essential oil layer when feeding, some pure water that has not been separated in time may be discharged along with the essential oil when discharging the essential oil, which will affect the purity of the essential oil. Utility Model Content

[0007] The purpose of the present invention is to at least solve one of the technical defects described in the background technology.

[0008] To this end, one purpose of the present utility model is to propose an oil-water separation device for processing plant essential oils, aiming to solve the problem of slow separation efficiency of the oil-water separation device for processing plant essential oils in the prior art, and low purity of essential oils in the process of separating and discharging hydrosols and essential oils.

[0009] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the present invention provides an oil-water separation device for processing plant essential oils, including a separation box, the top of the separation box is fixedly connected to a feed pipe, the outer surface of the feed pipe is slidably connected to a guide pipe, the top of the outer surface of the guide pipe is fixedly connected to a first float box, the outer surface of the bottom end of the feed pipe is fixedly connected to a convex ring, and the inside of the top end of the guide pipe is fixedly connected to a limiting ring.

[0010] Preferably, any of the above schemes is that the bottom of the separation box is fixedly connected to a first discharge pipe, the bottom of the separation box is fixedly connected to a second discharge pipe, one end of the second discharge pipe passing through the separation box is fixedly connected to a hose, the outer surface of the top end of the hose is fixedly connected to a connecting sleeve, and the top of the connecting sleeve is fixedly connected to a second float tank, so that the essential oil in the upper part of the essential oil layer is always discharged, so that the discharged essential oil has a higher purity.

[0011] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0012] 1. A guide tube is slidably connected to the outer surface of the feed tube, and a first float is provided on the guide tube, so that the first float can float on the top surface of the essential oil layer in the separation box, and the discharge port at the bottom end of the guide tube is located above and below the dividing line between the essential oil layer and the hydrosol layer. Therefore, the hydrosol and essential oil mixture entering the separation box through the feed tube will directly reach the dividing line, and then the hydrosol sinks and the essential oil goes upward, thereby improving the separation efficiency.

[0013] 2. Since the mixture of hydrosol and essential oil directly enters the dividing line through the guide tube, the hydrosol in the mixture sinks and the essential oil goes upward, so that the hydrosol will not pass through the entire essential oil layer. Therefore, when the hydrosol and essential oil are separated and discharged, the essential oil discharged through the second discharge pipe will not contain too much hydrosol, thereby ensuring the purity of the essential oil.

[0014] 3. By setting up the hose and the second float tank, the second float tank ensures that the top end of the hose is always located above the essential oil layer. Since the mixture of essential oil and hydrosol directly enters the dividing line, the essential oil in the upper part of the essential oil layer has a longer standing time and is thus purer. Therefore, when the valve on the second discharge pipe is opened, the discharged essential oil has a higher purity.

[0026] The utility model provides an oil-water separation device for processing plant essential oils.

[0027] Example 1:

[0028] like Figure 1 、 Figure 2 and Figure 6 As shown, it includes a separation box 1, a feed pipe 2 is fixedly connected to the top of the separation box 1, a guide pipe 3 is slidably connected to the outer surface of the feed pipe 2, and a first float 31 is fixedly connected to the top of the outer surface of the guide pipe 3. The first float 31 floats on the top of the liquid in the separation box 1, and the guide pipe 3 is inserted into the essential oil layer of the liquid, so that the bottom end of the guide pipe 3 is located above and below the boundary line between the essential oil layer 6 and the hydrosol layer 5. As the liquid level in the separation box 1 rises and falls, the first float 31 rises and falls accordingly, so that the bottom end of the guide pipe 3 rises and falls accordingly, thereby ensuring that the guide pipe 3 is always located above and below the boundary line between the essential oil layer and the hydrosol layer. The outer surface of the bottom end of the feed pipe 2 is fixedly connected There is a convex ring 21, and the top of the guide tube 3 is fixedly connected to a limiting ring 32. The inner diameter of the limiting ring 32 is equal to the outer diameter of the feed tube 2, and the outer diameter of the convex ring 21 is equal to the inner diameter of the guide tube 3. The limiting ring 32 and the convex ring 21 restrain each other so that when there is no liquid in the separation box 1, the guide tube 3 will not fall off. The bottom of the separation box 1 is fixedly connected to a first discharge pipe 11, and the first discharge pipe 11 is used to discharge pure water. The outer surface of the separation box 1 is fixedly connected to a second discharge pipe 12, and the second discharge pipe 12 is used to discharge the essential oil in the upper layer. Valves 13 are provided on the first discharge pipe 11 and the second discharge pipe 12 to control the discharge rate of essential oil and pure water.

[0029] Specifically, a support leg 14 is fixedly connected to the bottom of the separation box 1 , and a transparent plate 15 is provided on the outer surface of the separation box 1 to facilitate observation of the liquid level in the separation box 1 , as well as the essential oil layer 6 and the hydrosol layer 5 .

[0030] Example 2:

[0031] like Figure 3-6 As shown, the difference from Example 1 is that the bottom of the separation box 1 is fixedly connected to a first discharge pipe 11, the bottom of the separation box 1 is fixedly connected to a second discharge pipe 12, the second discharge pipe 12 passes through the separation box 1 and is fixedly connected to a hose 4 at one end, the outer surface of the top end of the hose 4 is fixedly connected to a connecting sleeve 41, and the top of the connecting sleeve 41 is fixedly connected to a second float 42, and the second float 42 can float on the top surface of the liquid in the separation box 1, so that the top end of the hose 4 can be close to the top surface of the essential oil layer 6, so that the essential oil discharged through the hose 4 is the essential oil in the top layer, and the purity is higher.

[0032] The working principle of the utility model is as follows: when in use, the mixture of hydrosol and essential oil is fed into the separation box 1 through the feed pipe 2, and the hydrosol and essential oil are separated into layers in the separation box 1. Figure 5 As shown, the first buoyancy tank 31 floats on the top of the essential oil layer 6, the guide tube 3 is inserted into the essential oil layer 6, and the bottom discharge port is located above and below the dividing line between the essential oil layer 6 and the pure dew layer 5. Therefore, the mixture of essential oil and pure dew discharged through the guide tube 3 will directly enter the junction between the essential oil layer 6 and the pure dew layer 5. The pure dew in the mixture sinks and the essential oil will move upward, thereby achieving rapid separation, and the second buoyancy tank 42 floats on the top of the essential oil layer 6, so that the top end of the hose 4 is located at the upper part of the essential oil layer 6, thereby opening the valve 13 on the second discharge pipe 12, allowing the essential oil in the upper layer to be discharged through the second discharge pipe 12. Since the essential oil in the upper layer has a longer standing time, it is purer, thereby making the essential oil discharged from the second discharge pipe 12 purer.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. By slidingly connecting the guide tube 3 on the outer surface of the feed tube 2, and providing a first float 31 on the guide tube 3, the first float 31 can float on the top surface of the essential oil layer 6 in the separation box 1, and the discharge port at the bottom end of the guide tube 3 is located above and below the dividing line between the essential oil layer 6 and the hydrosol layer 5. Therefore, the hydrosol and essential oil mixture entering the separation box 1 through the feed tube 2 will directly reach the dividing line, and then the hydrosol sinks and the essential oil goes upward, thereby improving the separation efficiency.

[0035] 2. Since the mixture of hydrosol and essential oil directly enters the position of the dividing line through the guide tube 3, the hydrosol in the mixture sinks and the essential oil goes upward, so that the hydrosol will not pass through the entire essential oil layer 6. Therefore, when the hydrosol and essential oil are discharged while separating, the essential oil discharged through the second discharge pipe 12 will not contain too much hydrosol, thereby ensuring the purity of the essential oil.

[0036] 3. By providing the hose 4 and the second float 42, the second float 42 allows the top end of the hose 4 to always be located above the essential oil layer 6. Since the mixture of essential oil and hydrosol directly enters the dividing line, the essential oil in the upper part of the essential oil layer 6 has a longer standing time and is thus purer. Therefore, when the valve 13 on the second discharge pipe 12 is opened, the discharged essential oil has a higher purity.
