Technical Field

[0001] This utility model relates to the field of natural plant essential oil processing technology, specifically to a device for purifying and separating Artemisia argyi essential oil. Background Technology

[0002] Artemisia argyi, a traditional Chinese medicine, has an essential oil that is rich in active ingredients such as eucalyptol, camphor, and terpenoids. It has important value in the fields of medicine, health care, and cosmetics. Currently, the main extraction technologies for Artemisia argyi essential oil include steam distillation, solvent extraction, and supercritical CO2 extraction.

[0003] In the current extraction process of Artemisia argyi essential oil, traditional centrifugal separation equipment has problems such as difficulty in separating residue from essential oil and lack of dynamic disturbance in the light phase essential oil liquid film. Tiny oil droplets are difficult to effectively aggregate, resulting in low collection rate and increased energy consumption in subsequent distillation. In addition, the equipment structure is complex and difficult to adapt to the needs of small-scale production. Utility Model Content

[0004] The purpose of this invention is to provide a purification and separation device for Artemisia argyi essential oil, which solves the problems mentioned in the background art, such as the difficulty in separating residue from essential oil and the lack of dynamic disturbance in the light phase essential oil liquid film of traditional centrifugal separation equipment, making it difficult for tiny oil droplets to effectively aggregate, resulting in low collection rate and increased energy consumption for subsequent distillation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a purification and separation device for Artemisia argyi essential oil, comprising a top cover and a conical cylinder. A rotating rod is rotatably connected to the bottom center of the top cover. Several crushing blades are fixedly connected to the lower end of the outer surface of the rotating rod. The rotating rod passes through the surface of an interception frame and is rotatably connected to the interception frame through a bearing seat. A filter screen is fixedly connected to the inner side wall of the interception frame. Two electric push rods are fixedly connected between the interception frame and the bottom of the top cover. The interception frame and the crushing blades are located inside the conical cylinder.

[0006] In this technical solution, the raw materials inside the conical cylinder are crushed and cut by the crushing blades, releasing the active ingredients of the essential oils, which are then blocked by the intercepting frame. The conical cylinder itself rotates and centrifuges, separating the light phase essential oils from the heavy phase residues, effectively improving the purification efficiency and purity of the essential oils and shortening the process cycle.

[0007] Preferably, the top cover is installed at the top of the tank, the inner side wall of the tank is fixedly connected to a collection ring channel, and the conical cylinder is rotatably connected to the center of the top of the collection ring channel.

[0008] Preferably, two horizontal blocks are fixedly connected to the outer wall of the conical cylinder, a bottom plate is fixedly connected to the bottom of the tank, a second motor is fixedly connected to the center of the bottom of the bottom plate, and the tail end of the drive shaft of the second motor is connected to the bottom of the conical cylinder.

[0009] Preferably, the bottom of the collection ring channel has two upper lifting grooves, and the bottom plate surface directly below the upper lifting grooves has a lower lifting groove. A feeding pipe is vertically slidably connected between the upper and lower lifting grooves, and a spiral channel is fixedly connected to the inner side of the feeding pipe.

[0010] Preferably, a fixing ring is fixedly connected to the outer wall of the feeding pipe, a limiting block is fixedly connected to the top of the fixing ring, a limiting groove is formed on the bottom surface of the collecting ring channel directly above the limiting block, and the top of the limiting block is located inside the limiting groove and is slidably connected to the limiting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a conical cylinder. Inside the conical cylinder, the raw materials are crushed and cut by the crushing blades, releasing the active ingredients of the essential oil. These ingredients are then blocked by the intercepting frame. The conical cylinder itself rotates and centrifuges, separating the light phase essential oil from the heavy phase residue. This effectively improves the efficiency and purity of essential oil purification, shortens the process cycle, and the equipment has a high degree of integration, making it easy to achieve miniaturized production.

[0015] 2. This utility model generates vibration by continuously pushing the fixed ring and the feed pipe up and down during the centrifugation process of the conical cylinder. The vibration is transmitted to the essential oil film through the spiral channel, promoting the collision and aggregation of tiny oil droplets, significantly improving the essential oil collection rate and fluidity, and reducing the energy consumption of subsequent distillation.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0023] A device for purifying and separating Artemisia argyi essential oil, see [link / reference]. Figures 1 to 4 The system includes a top cover 101 and a conical cylinder 5. The top cover 101 is installed at the top of the tank body 1. A collection ring channel 7 is fixedly connected to the inner wall of the tank body 1. A rotating rod 201 is rotatably connected to the bottom center of the top cover 101. A motor 2 is fixedly connected to the top center of the top of the top cover 101. The tail end of the drive shaft of the motor 2 is connected to the top of the rotating rod 201. Several crushing blades 202 are fixedly connected to the lower end of the outer surface of the rotating rod 201. The rotating rod 201 passes through the surface of the interception frame 4 and is rotatably connected to the interception frame 4 through a bearing seat. A filter screen 401 is fixedly connected to the inner wall of the interception frame 4. Two electric push rods 3 are fixedly connected between the interception frame 4 and the bottom of the top cover 101. The interception frame 4 and the crushing blades 202 are located inside the conical cylinder 5. The conical cylinder 5 is rotatably connected to the top center of the collection ring channel 7. In use, the top cover 101 is opened. The top cover 101 is used to place the raw materials into the conical cylinder 5, and then the top cover 101 is closed. At this time, the rotating rod 201 and the crushing blade 202 will enter the conical cylinder 5. The electric push rod 3 drives the intercepting frame 4 to descend, blocking the opening of the conical cylinder 5. The first motor 2 can drive the rotating rod 201 and the crushing blade 202 to rotate, crushing the raw materials. After crushing, the conical cylinder 5 can rotate itself to centrifuge the light phase essential oil components, thereby achieving the separation of raw materials and essential oils. The presence of the intercepting frame 4 and the filter screen 401 can prevent the raw materials from falling off and ensure the purity of the essential oil components at the centrifugation point. It should be noted that there is a small gap between the intercepting frame 4 and the conical cylinder 5 to avoid affecting the normal rotation of the conical cylinder 5. When the electric push rod 3 is extended to its maximum extent, it can ensure that the intercepting frame 4 reaches the set position.

[0024] Specifically, such as Figure 2 and Figure 3As shown, two horizontal blocks 6 are fixedly connected to the outer wall of the conical cylinder 5, and a bottom plate 8 is fixedly connected to the bottom of the tank body 1. A second motor 13 is fixedly connected to the center of the bottom of the bottom plate 8. The tail end of the drive shaft of the second motor 13 is connected to the bottom of the conical cylinder 5. After the second motor 13 is started, it will drive the conical cylinder 5 to rotate, and the speed can be adjusted.

[0025] Furthermore, such as Figure 2 and Figure 4 As shown, a fixing ring 11 is fixedly connected to the outer wall of the feeding pipe 9. A limiting block 12 is fixedly connected to the top of the fixing ring 11. A limiting groove 701 is opened on the bottom surface of the collection ring channel 7 directly above the limiting block 12. The top of the limiting block 12 is located inside the limiting groove 701 and is slidably connected to the limiting groove 701. The limiting block 12 is inserted into the limiting groove 701, thereby ensuring that the feeding pipe 9 can only move vertically up and down and will not rotate or deviate. During the centrifugation process of the conical cylinder 5, the horizontal block 6 on its outer wall will continuously push and contact the fixing ring 11 on the outer wall of the feeding pipe 9, causing the feeding pipe 9 to move up and down and generate vibration, which accelerates the aggregation of essential oil components, making it convenient for collection and subsequent processing. It should be noted that the far end of the horizontal block 6 is set as a hemispherical shape, and the bottom of the fixing ring 11 is also designed with rounded corners. Both surfaces are very smooth and easy to contact.

[0026] Furthermore, such as Figure 2 As shown, the bottom of the collection ring channel 7 has two upper lifting grooves 702, and the surface of the bottom plate 8 directly below the upper lifting grooves 702 has a lower lifting groove 801. A feed pipe 9 is vertically slidably connected between the upper lifting grooves 702 and the lower lifting grooves 801. The feed pipe 9 moves vertically between the upper lifting grooves 702 and the lower lifting grooves 801, and the diameter of the feed pipe 9 is consistent with the inner diameter of the upper lifting grooves 702 and the lower lifting grooves 801 to ensure stable vertical movement. A spiral channel 10 is fixedly connected to the inner side of the feed pipe 9. The spiral channel 10 can make the essential oil components rotate and flow downwards. With the up and down vibration of the feed pipe 9, the aggregation time and path length are increased.

[0027] It is worth noting that, such as Figure 2 As shown, the upper lifting groove 702 is connected to the collection ring channel 7, and the lower lifting groove 801 is connected to the discharge port 802 opened at the bottom of the base plate 8. The essential oil components entering the collection ring channel 7 will pass through the upper lifting groove 702 into the discharge pipe 9, and then pass through the lower lifting groove 801 from the discharge pipe 9 and leave from the discharge port 802. It should be noted that the upper and lower surface edges of the discharge pipe 9 will be provided with sealing rings to ensure that the essential oil components will not flow out from the gap between the upper lifting groove 702 and the lower lifting groove 801.

[0028] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0029] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
