Description

Technical Field

[0001] This utility model relates to the field of volatile oil extraction technology, and in particular to a device for extracting volatile oil. Background Technology

[0002] Volatile oils, also known as essential oils, are a type of volatile, oily liquid that can be distilled with steam. Most of them have aroma and have effects such as inducing sweating, regulating qi, relieving pain, inhibiting bacteria, and improving taste. They play an irreplaceable role in the fields of medicine and food.

[0003] Chinese patent document CN214830210U discloses an extraction device for volatile oils, relating to the field of volatile oil extraction technology. It includes a mounting frame with an extraction tank mounted on it. An air inlet pipe is connected to the top of the extraction tank, and the other end of the air inlet pipe is connected to a condenser. A liquid outlet pipe is connected to one side of the condenser, and the other end of the liquid outlet pipe is connected to an oil-water separator. A drain pipe is connected to the bottom of the oil-water separator, and the bottom end of the drain pipe is connected to a collection tank. An oil drain pipe is connected to one side of the oil-water separator, and the other end of the oil drain pipe is connected to an oil collection tank. By incorporating a first motor, a first rotating shaft, and spiral blades, when the raw material is heated in the extraction tank, the first motor rotates, driving the first rotating shaft to rotate. The first rotating shaft then drives the spiral blades to rotate. The rotation of the spiral blades stirs the raw material in the extraction tank, ensuring uniform flow and heating, while preventing the raw material from caking, accumulating, or sticking to the bottom. It also breaks down the raw material to a certain extent, thus achieving high volatile oil extraction efficiency.

[0004] The existing technology has the following problems:

[0005] When using volatile oil extraction equipment, the extraction results for light oils and heavy oils with small specific gravity differences are not ideal, which affects the use of the equipment. Furthermore, the equipment cannot vent the raw materials after use, which affects its reheating and reuse. Utility Model Content

[0006] This invention provides an extraction device for volatile oils to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] An extraction device for volatile oil includes a fixed frame. An extraction component is fixedly connected to the inner wall of the lower left portion of the fixed frame. An air inlet pipe is fixedly connected to the upper surface of the extraction component. A primary condenser is fixedly connected to the right side of the upper portion of the air inlet pipe. The upper surface of the primary condenser is fixedly connected to the top of the inner wall of the fixed frame. An oil-water separation component is fixedly connected to the lower surface of the primary condenser and is located to the right of the extraction component. The outer wall of the oil-water separation component is fixedly connected to the inner wall of the lower right portion of the fixed frame.

[0009] Preferably, the extraction assembly includes an extraction tank, the outer wall of which is fixedly connected to the inner wall of the fixing frame, and a heating inner shell is fixedly connected to the inner wall of the extraction tank.

[0010] Preferably, the oil-water separation component includes a liquid outlet, a buffer tank is fixedly installed on the lower surface of the liquid outlet, a cooling jacket is fixedly connected to the outer wall of the buffer tank, and the outer wall of the cooling jacket is fixedly connected to the inner wall of the fixing frame.

[0011] Preferably, the inner wall of the lower part of the heating inner shell is funnel-shaped, and the lower surface of the heating inner shell overlaps with the upper surface of the center part of the discharge port.

[0012] Preferably, the outer wall of the first cooling jacket is fixedly connected to the inner wall of the fixing frame, and a water inlet pipe is fixedly connected to the right side of the first cooling jacket.

[0013] Preferably, the upper surface of the extraction tank is fixedly connected to a feed inlet, and the lower surface of the extraction tank is fixedly connected to a discharge outlet.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] 1. This utility model provides a device for extracting volatile oils. By using a buffer tank, the flow rate of the condensed liquid is slowed down. Then, under the action of the first cooling jacket, the temperature of the condensate inside the buffer tank can be regulated and controlled. Then, the narrow oil collector increases the aggregation time of the separated volatile oil at the oil-water interface, ensuring that small oil droplets quickly aggregate into large oil droplets that are suspended or sink. Then, cooling water is introduced into the second cooling jacket to regulate the temperature of the condensate inside the narrow oil collector, which is conducive to the settling speed of heavy oil, thereby improving the oil-water separation effect and increasing the extraction rate of highly difficult volatile oils. The extraction rate of volatile oils is increased from the initial 0.03% to 0.17%, an increase of nearly 6 times.

[0018] 2. This utility model provides a device for extracting volatile oils. By heating the inner shell, the raw materials in the inner wall of the inner shell can be heated and volatilized. The volatilized gas is then transported to the interior of the first-stage condenser through the air inlet pipe. Since the inner wall of the lower part of the heating inner shell is funnel-shaped, the volatilized material can be fully discharged during discharge, thereby preventing internal residue.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 As shown, an extraction device for volatile oil includes a fixed frame 1. An extraction component 2 is fixedly connected to the inner wall of the lower left part of the fixed frame 1. An air inlet pipe 3 is fixedly connected to the upper surface of the extraction component 2. A primary condenser 4 is fixedly connected to the right side of the upper part of the air inlet pipe 3. The upper surface of the primary condenser 4 is fixedly connected to the top of the inner wall of the fixed frame 1. An oil-water separation component 5 is fixedly connected to the lower surface of the primary condenser 4 and is located to the right of the extraction component 2. The outer wall of the oil-water separation component 5 is fixedly connected to the inner wall of the lower right part of the fixed frame 1.

[0027] First, the raw material is put into the extraction component 2. Under the action of the extraction component 2, the raw material is heated evenly, so that the gas generated by distillation can enter the first-stage condenser 4 through the air inlet pipe 3 for condensation. The condensed steam becomes oil and water and enters the oil-water separation component 5. Then, under the action of the oil-water separation component 5, oil-water separation is performed.

[0028] like Figure 2As shown, the oil-water separation assembly 5 includes an outlet 51, a buffer tank 52 is fixedly installed on the lower surface of the outlet 51, a cooling jacket 53 is fixedly connected to the outer wall of the buffer tank 52, and the outer wall of the cooling jacket 53 is fixedly connected to the inner wall of the fixing frame 1; a delivery pipe 54 is fixedly installed on the lower surface of the buffer tank 52, and a narrow oil collector 55 is fixedly installed on the right side of the delivery pipe 54.

[0029] The buffer tank 52 slows down the flow rate of the condensate. Then, under the action of the cooling jacket 53, the temperature of the condensate inside the buffer tank 52 can be regulated and controlled. The narrow oil collector 55 increases the aggregation time of the separated volatile oil at the oil-water interface, ensuring that small oil droplets quickly aggregate into large oil droplets that are suspended or sink.

[0030] like Figure 3 As shown, the outer wall of the upper part of the elongated oil collector 55 is fixedly connected to the inner wall of the fixing frame 1, and the outer wall of the lower part of the elongated oil collector 55 is fixedly connected to the cooling jacket 2 56.

[0031] By introducing cooling water into the interior of the cooling jacket 56, the temperature of the condensate inside the narrow oil collector 55 is regulated, which is beneficial to the settling speed of heavy oil, thereby improving the oil-water separation effect and increasing the extraction rate of highly volatile oils. The extraction rate of volatile oils is increased from the initial 0.03% to 0.17%, an increase of nearly 6 times.

[0032] like Figure 4 As shown, the extraction assembly 2 includes an extraction tank 21. The outer wall of the extraction tank 21 is fixedly connected to the inner wall of the fixing frame 1. A heating inner shell 24 is fixedly connected to the inner wall of the extraction tank 21. The lower part of the inner wall of the heating inner shell 24 is funnel-shaped, and the lower surface of the heating inner shell 24 overlaps with the upper surface of the center part of the discharge port 23.

[0033] By heating the inner shell 24, the raw materials inside the inner wall of the inner shell 24 can be heated and volatilized. The volatilized gas is then transported to the interior of the first-stage condenser 4 through the air inlet pipe 3. Since the lower part of the inner wall of the inner shell 24 is funnel-shaped, the volatilized material can be fully discharged during discharge, thus preventing internal residue.

[0034] An inlet 22 is fixedly connected to the upper surface of the extraction tank 21, and a discharge port 23 is fixedly connected to the lower surface of the extraction tank 21.

[0035] The feed inlet 22 allows the raw material to be fed into the inner wall of the extraction tank 21 and the heated inner shell 24, and then discharged through the discharge outlet 23 after processing.

[0036] like Figure 5 As shown, the outer wall of the cooling jacket 53 is fixedly connected to the inner wall of the fixing frame 1, and a water inlet pipe is fixedly connected to the right side of the cooling jacket 53.

[0037] Cooling water is introduced into the cooling jacket 53 through the water inlet pipe, thereby allowing real-time temperature control of the buffer tank 52.

[0038] The working principle of this utility model is as follows: First, the raw material is fed into the inner wall of the extraction tank 21 and the heating inner shell 24 through the feed inlet 22. Then, the raw material is heated by the heating inner shell 24. The gas generated by distillation enters the first-stage condenser 4 through the gas inlet pipe 3 for condensation. The condensed vapor becomes oil and water and enters the buffer tank 52 through the liquid outlet 51. The buffer tank 52 slows down the flow rate of the condensed liquid. Then, under the action of the first cooling jacket 53, the temperature of the condensate inside the buffer tank 52 can be regulated and controlled. Then, the narrow oil collector 55 increases the aggregation time of the separated volatile oil at the oil-water interface, ensuring that small oil droplets quickly aggregate into large oil droplets that are suspended or sink. Then, cooling water is added into the second cooling jacket 56 to regulate the temperature of the condensate inside the narrow oil collector 55, which is beneficial to the settling speed of heavy oil.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
