Description

Technical Field

[0001] This utility model belongs to the field of plant essential oil processing technology, specifically relating to a waste treatment device for plant essential oil extraction. Background Technology

[0002] In the field of plant essential oil extraction, steam distillation is widely used due to its simple operation and low cost. The principle is to heat the plant raw material with steam to make the essential oil volatilize, and then condense and separate it to obtain the essential oil product. However, existing extraction equipment still has some shortcomings in terms of waste treatment and extraction efficiency.

[0003] In traditional equipment, after the plant raw materials are steam distilled, the solid residue and liquid mixture are often discharged together, requiring additional solid-liquid separation treatment. This not only increases the process cost, but may also lead to waste of essential oil residue due to incomplete separation. In addition, although some equipment is equipped with a filtration structure, it is mostly a single filtration stage, which makes it difficult to classify and collect waste of different particle sizes, affecting the subsequent resource utilization of waste. Utility Model Content

[0004] The purpose of this invention is to provide a waste treatment device for plant essential oil extraction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste treatment device for plant essential oil extraction, comprising an extraction tank, wherein a steam generator is provided on one side of the extraction tank, and the steam generator is connected to the extraction tank via a conduit; The extraction tank is equipped with a No. 1 waste collection component and a No. 2 waste collection component inside; The No. 1 waste collection assembly includes a material throwing cylinder, a connecting plate, a movable shaft, a fixed frame, and a drive motor. The outer wall of the material throwing cylinder has a through hole. The material throwing cylinder is connected to the movable shaft through the connecting plate. The movable shaft is connected to the output end of the drive motor on the fixed frame. The second waste collection assembly includes a first filter frame and a second filter frame. The first filter frame is located above the second filter frame, and the aperture of the first filter frame is larger than that of the second filter frame.

[0006] In a preferred embodiment, the extraction tank is provided with a rectangular groove structure, and the first filter frame and the second filter frame are pulled out and disposed in the rectangular groove structure of the extraction tank.

[0007] In a preferred embodiment, the filter plate of the second filter frame is provided with a spacer cavity, and the spacer cavity is provided with a retaining plate of the same aperture, the retaining plate being pulled out of the spacer cavity.

[0008] In a preferred embodiment, the extraction tank is further provided with a support plate, and the support plate is provided with a limiting post, which is embedded in a limiting cavity reserved below the material throwing cylinder.

[0009] In a preferred embodiment, a conical inlet is provided below the extraction tank, the conical inlet is located below the second waste collection component, and the conical inlet is connected to the essential oil collection tank below.

[0010] In a preferred embodiment, the fixed frame has an annular cavity groove in the middle, the movable disk of the movable shaft is rotatably disposed in the annular cavity groove, the movable disk has a toothed cavity, the output end of the drive motor is fixed with a transmission tooth, and the transmission tooth meshes with the toothed cavity.

[0011] In a preferred embodiment, the extraction tank is provided with a first cover plate and a second cover plate. The first cover plate is fixed to the extraction tank with bolts, and the second cover plate is engaged with the first cover plate. The movable shaft passes through the annular cavity formed by the combination of the first cover plate and the second cover plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This waste treatment device for plant essential oil extraction achieves preliminary solid-liquid separation through the slinging cylinder of the first waste collection component. After solid-liquid separation, some larger impurities are retained in the slinging cylinder and then subjected to graded filtration through the first and second filter frames with different pore sizes in the second waste collection component. This allows waste of different particle sizes to be collected separately, achieving complete separation without additional processes. This avoids waste of essential oil residue and facilitates subsequent resource utilization of waste, solving the problem that a single filtration stage cannot meet the requirements for graded collection. This waste treatment device for plant essential oil extraction features a pull-out retainer plate installed in the filter plate spacer cavity of the second filter frame. The retainer plate has the same pore size as the filter plate. By adjusting the insertion position of the retainer plate, the pore size distribution of the actual effective filtration area of ​​the filter plate can be changed. When the retainer plate is fully inserted, the pore sizes of the filter plate and the retainer plate overlap to form a finer filtration structure, suitable for filtering fine impurities. When the retainer plate is partially removed, the original pore size of the filter plate can be restored to meet conventional filtration needs. This design allows for flexible adjustment of the actual filtration accuracy of the second filter frame, enabling the device to adapt to different types of plant essential oil extraction scenarios. It reduces the frequency and cost of replacing filter components and improves the versatility and ease of operation of the device. Attached Figure Description

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figures 1-5 This utility model provides a waste treatment device for plant essential oil extraction, including an extraction tank 1. A steam generator 2 is provided on one side of the extraction tank 1. The steam generator 2 is connected to the extraction tank 1 through a conduit 3. The extraction chamber of the extraction tank 1 is provided with a first waste collection component 4 and a second waste collection component 5. The first waste collection component 4 includes a throwing cylinder 41, a connecting plate 42, a movable shaft 43, a fixed frame 44, and a drive motor 45. The outer wall of the throwing cylinder 41 is provided with a through hole. The throwing cylinder 41 is connected to the movable shaft 43 through the connecting plate 42. The movable shaft 43 is connected to the output end of the drive motor 45 on the fixed frame 44. The second waste collection component 5 includes a first filter frame 51 and a second filter frame 52. The first filter frame 51 is located above the second filter frame 52, and the aperture of the first filter frame 51 is larger than that of the second filter frame 52. The extraction tank 1 is provided with a rectangular groove structure. The first filter frame 51 and the second filter frame 52 are pulled out and installed in the rectangular groove structure of the extraction tank 1.

[0018] In this embodiment, by setting up the material-spinning cylinder 41 of the first waste collection component 4, the plant raw materials are initially separated into solid and liquid by utilizing the through holes in its outer wall. After the solid-liquid separation, some larger impurities are retained in the material-spinning cylinder 41. Combined with the first filter frame 51 and the second filter frame 52 with different pore sizes in the second waste collection component 5, a two-stage progressive filtration structure is formed. The first filter frame 51 filters out larger solid waste particles, and the second filter frame 52 further traps fine impurities. This effectively avoids the problem of incomplete filtration caused by the mixing of waste particles of different sizes, improves the separation effect of essential oil and waste, and ensures the purity of the extracted essential oil.

[0019] In this embodiment, the rectangular groove structure of the extraction tank 1 provides a pull-out installation method for the first filter frame 51 and the second filter frame 52. This design allows the filter frames to be installed, disassembled, and cleaned without the need for complex tools, enabling operators to quickly complete replacement or impurity cleaning, thus significantly shortening the device maintenance time.

[0020] Please see Figure 4 and Figure 5 The filter plate of the second filter frame 52 is provided with a partition cavity 521, and a card plate 53 with the same aperture is provided in the partition cavity 521. The card plate 53 is pulled out and installed in the partition cavity 521.

[0021] In this embodiment, the filter plate of the second filter frame 52 is provided with a spacer cavity 521, and a card plate 53 with the same aperture is provided in the spacer cavity 521. The effective filtration area of ​​the filter plate can be changed by pulling the card plate 53. When the card plate 53 is fully inserted into the spacer cavity 521, the filter plate and the card plate 53 are superimposed to form a denser filtration structure, which can intercept finer impurities. When the card plate 53 is partially pulled out, the effective filtration area can be increased to adapt to situations with a high impurity content. This design allows the second filter frame 52 to be flexibly adjusted in terms of filtration precision without the need for overall replacement, meeting the differentiated filtration effect requirements of different plant raw materials and improving the versatility of the device.

[0022] The spacer cavity 521 and the card plate 53 are provided with anti-slip textures on both sides. When the card plate 53 is inserted into the spacer cavity 521, the anti-slip textures on both sides come into contact with each other, which can increase the friction of the contact surface, further enhance the stability of the card plate 53 in the spacer cavity 521, effectively resist liquid impact, and prevent the card plate 53 from shifting.

[0023] Please see Figures 1-3 The extraction tank 1 is also provided with a support plate 46, and a limiting post is provided on the support plate 46. The limiting post is embedded in the limiting cavity reserved below the throwing cylinder 41.

[0024] In this embodiment, the setting of the limiting post can provide stable support for the rotating material throwing cylinder 41 and effectively counteract the radial shaking generated when the material throwing cylinder 41 rotates.

[0025] Please see Figure 1 and Figure 2 A conical inlet 11 is provided below the extraction tank 1. The conical inlet 11 is located below the second waste collection component 5, and the conical inlet 11 is connected to the essential oil collection bucket below.

[0026] In this embodiment, the conical inlet 11 is designed to utilize gravity to guide the essential oil after it has been filtered by the waste collection component 5. This allows the essential oil to quickly converge along the inner wall of the conical inlet to the bottom outlet, reducing the amount of essential oil remaining at the bottom of the extraction tank 1, reducing essential oil loss, and improving the collection rate of essential oil.

[0027] Please see Figure 3 The fixed frame 44 has an annular groove 441 in the middle position. The movable disk 431 of the movable shaft 43 is rotatably disposed in the annular groove 441. The movable disk 431 has a toothed cavity. The output end of the drive motor 45 is fixed with a transmission tooth 451, which meshes with the toothed cavity.

[0028] In this embodiment, the annular groove 441 provides stable rotational support for the movable disc 431, effectively limiting the radial sway of the movable shaft 43 and ensuring the coaxiality of the movable shaft 43 when driving the material-throwing cylinder 41 to rotate at high speed, reducing vibration caused by eccentric rotation. Secondly, the meshing transmission method between the transmission gear 451 and the gear cavity is more efficient and the power transmission is smoother than the traditional direct connection of the coupling, avoiding slippage and ensuring that the power of the drive motor 45 is accurately transmitted to the movable shaft 43, making the rotational speed of the material-throwing cylinder 41 stable and controllable, which is beneficial to improving the uniformity and efficiency of essential oil extraction.

[0029] Please see Figures 1-3 The extraction tank 1 is provided with a first cover plate 12 and a second cover plate 121. The first cover plate 12 is fixed to the extraction tank 1 with bolts, and the second cover plate 121 is engaged with the first cover plate 12. The movable shaft 43 passes through the annular cavity formed by the combination of the first cover plate 12 and the second cover plate 121.

[0030] In this embodiment, the snap-fit ​​design between the second cover plate 121 and the first cover plate 12 allows the operator to quickly open and close the second cover plate 121, making it convenient to add raw materials into the material discharge cylinder 41 or to inspect and maintain the interior of the extraction tank 1 without disassembling the bolts.

[0031] In the above scheme, it should be noted that: the steam generator 2 in this application is specifically the existing LDR0.043 - 0.7 electric boiler steam generator. Since it is an existing product, and the specific structure and working principle of the steam generator 2 are all existing publicly disclosed technologies, they will not be described in detail here.

[0032] Working principle and usage process of this utility model: First, open the second cover plate 121 above the extraction tank 1, pour the pre-treated plant raw materials into the feeding cylinder 41, and then close the second cover plate 121. Next, start the steam generator 2 and introduce steam into the extraction tank 1 through the conduit 3. At the same time, turn on the drive motor 45. The drive motor 45 meshes with the tooth cavity on the movable disc 431 through the transmission gear 451, driving the movable shaft 43 and the throwing cylinder 41 to rotate at high speed. The movable disc 431 rotates stably in the annular groove 441 of the fixed frame 44. At this time, the plant raw materials are heated by steam and subjected to centrifugal force in the spinning drum 41. The essential oil and juice are thrown out through the through hole in the drum wall. Larger impurities are retained in the spinning drum 41. The mixture falls to the second waste collection component 5. Large particles of impurities are filtered by the first filter frame 51, and then small impurities are intercepted by the second filter frame 52 (and the card plate 53 combined structure). The pure essential oil flows into the collection bucket along the conical inlet 11. After the extraction is completed, first turn off the steam generator 2 and the drive motor 45. After the device has cooled down, open the second cover plate 121. Since the fixing frame 44 is detachably connected with bolts, the fixing frame 44 and the throwing cylinder 41 can be removed from the extraction tank 1 as a whole. Then, remove the connecting plate 42, clean the residual solid waste in the throwing cylinder 41, and then pull out the first filter frame 51 and the second filter frame 52 to pour out the filtered impurities.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
