Abstract
Description
Technical Field
[0001] This utility model relates to the field of plant essential oil filtration and impurity removal, and in particular to a plant essential oil filtration and impurity removal device and system. Background Technology
[0002] In the field of plant essential oil production, with the increasing demand for natural plant essential oils, production scale and output are also continuously expanding. Plant essential oils have wide applications in many industries such as cosmetics, fragrances, and pharmaceuticals. High-quality plant essential oils play a crucial role in improving product quality and market competitiveness. Filtration and impurity removal, as a key step in the production process of plant essential oils, directly affects the purity and quality of the essential oils. With the development of the industry, the requirements for essential oil filtration and impurity removal technology are also becoming increasingly stringent, and efficient and precise filtration and impurity removal technology has become an important support for the industry's development.
[0003] In the traditional process of filtering and removing impurities from plant essential oils, several methods are commonly used. One method involves using a regular filter screen, placed in the channel through which the essential oil flows, to trap impurities based on the size of the mesh openings. This method is relatively simple and inexpensive. Another method uses filter paper, where filter paper is laid flat in the filtration device, allowing the essential oil to pass through and impurities to be filtered out. Additionally, there is centrifugal filtration, which uses centrifugal force to separate impurities from the essential oil. These methods are effective in filtering and removing impurities from essential oils to a certain extent and are widely used in the industry.
[0004] However, existing filtration and impurity removal methods have significant drawbacks. Ordinary filter screens have fixed mesh sizes, making them ineffective at intercepting smaller impurities, and they are prone to clogging, affecting filtration efficiency. While filter paper filtration can remove smaller impurities, its load-bearing capacity is limited, making it easily damaged and requiring frequent replacement. Centrifugal filtration equipment is expensive and ineffective at separating impurities with densities similar to essential oils. These problems make it difficult for existing filtration and impurity removal methods to meet the demands of high-quality plant essential oil production. Utility Model Content

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0028] like Figure 1-5 As shown in this embodiment, a plant essential oil filtration and impurity removal device and system are provided.
[0029] Example 1
[0030] The plant essential oil filtration and impurity removal device provided in this application includes a filter support 2 installed in a vacuum filtration tank 1. The filter support 2 is located near the first feed inlet of the vacuum filtration tank 1. The filter support 2 has several perforations 3 for the flow of essential oil and is covered with filter paper on the outside. The area of the top of the filter support 2 is smaller than that of the bottom, so that the side wall between the top and the bottom forms a slope. This design increases the filtration area, allowing the essential oil to come into more full contact with the filter paper and improving the filtration efficiency. At the same time, the slope structure also makes it easier for impurities to slide off and reduces clogging.
[0031] The filter holder 2 includes a top disc, a bottom disc, and side walls. The top and bottom discs have perforations 3 arranged radially or in an array. This arrangement allows essential oils to pass evenly through the perforations 3, improving the uniformity of filtration. A radial arrangement is like the spokes of a wheel, radiating outwards from the center; an array arrangement is neatly arranged in multiple rows and columns. The side walls are located between the top and bottom discs and have multiple rows of evenly spaced perforations 3. These perforations 3 allow essential oils to pass through from the sides, further increasing the filtration area. The arrangement of the perforations 3 on the top and bottom discs can be selected according to actual needs. A radial arrangement is suitable for situations where it is necessary to quickly guide the essential oil flow to the edges, while an array arrangement is more suitable for scenarios where uniform filtration is desired.
[0032] The perforations 3 near the center of the top disc have a smaller diameter, while the diameter of the perforations 3 increases towards the outer edges. This design is because the flow rate of essential oil is relatively low near the center, and the smaller diameter allows for more precise interception of small impurities. Conversely, the larger flow rate on the outer edges ensures that the essential oil passes through smoothly, improving overall filtration efficiency. For example, this gradient pore size design works better when processing essential oils containing impurities of varying sizes.
[0033] The bottom of the filter support 2 is provided with an outwardly protruding annular frame 4, and the inside of the filtration tank 1 is provided with a step 5. When the filter support 2 enters the filtration tank 1 from the first feed port of the filtration tank 1 and travels a certain distance, the annular frame 4 will be locked on the inner wall step 5 of the filtration tank 1. This design facilitates the installation and fixation of the filter support 2, ensuring that its position is stable during the filtration process and that it will not shake or shift.
[0034] The top and bottom transitions to the side walls are rounded. The rounded corners prevent stress concentration, enhance the structural strength of the filter support 2, and prevent impurities from accumulating at the corners, making cleaning and maintenance easier.
[0035] The bottom of the filtration tank 1 is provided with a first outlet 6, which is funnel-shaped. The funnel-shaped design allows the filtered essential oil to flow out more smoothly, reducing residue and improving the collection efficiency of the essential oil.
[0036] This plant essential oil filtration and impurity removal device features a unique filter support 2 design, which increases the filtration area and improves filtration efficiency. The perforations 3 on the filter support 2, in conjunction with the filter paper, effectively intercept impurities, while the sloping structure and rounded corners reduce clogging and accumulation. The funnel-shaped outlet at the bottom ensures smooth flow of essential oils. The overall structure is simple and practical, effectively addressing the shortcomings of existing filtration and impurity removal methods and meeting the demands of high-quality plant essential oil production.
[0037] Example 2
[0038] This embodiment provides a plant essential oil filtration and impurity removal system, including the aforementioned plant essential oil filtration and impurity removal device, and a collection tank 7 connected to the filtration tank 1. The collection tank 7 is also connected to a vacuum oil pump 8. The top of the collection tank 7 is provided with a second inlet and a vacuum port. The second inlet is connected to the filtration tank 1, and the vacuum port is connected to the vacuum oil pump 8. The bottom of the collection tank 7 is provided with a second outlet and a drain pipe. A Y-type filter 9 is provided on the second outlet.
[0039] The collection tank 7 is equipped with an upper sight glass 11 and a lower sight glass 12 for observing the liquid level inside the collection tank 7. The lower sight glass 12 is located below the upper sight glass 11. Through the upper sight glass 11 and the lower sight glass 12, the operator can observe the liquid level in the collection tank 7 at any time to avoid the liquid level being too high or too low, which would affect the normal operation of the system.
[0040] The system also includes a flatbed cart 10 for moving the system, with the vacuum oil pump 8, collection tank 7, and filtration tank 1 fixed on the flatbed cart 10. The design of the flatbed cart 10 gives the entire system good mobility, allowing its position to be flexibly adjusted according to production needs.
[0041] The pipe connecting the filtration tank 1 and the collection tank 7 is the filtrate pipe 13, which branches off to form a second drain pipe 14. The pipe connecting the vacuum oil pump 8 and the collection tank 7 is the vacuum pipe 16, which also branches off to form a vent pipe 17 for discharging air. The pipe connecting the second outlet of the collection tank 7 is the discharge pipe 18. Each pipe is equipped with a control valve 19. The control valve 19 can control the flow direction and flow rate of the essential oil and impurities, facilitating operation and adjustment of the system by the operator.
[0042] Filter paper is placed on filter holder 2, and plant essential oil is pumped into vacuum filtration tank 1. The ball valve on the filtrate pipe 13 is opened, and vacuum oil pump 8 is turned on. Under vacuum, the essential oil passes through the filter paper on filter holder 2 and enters collection tank 7 through filtrate pipe 13. The liquid level is observed through the lower sight glass 12 and upper sight glass 11 of collection tank 7. When the liquid reaches the specified level in upper sight glass 11, vacuum oil pump 8 is operated, and then the operation of vacuum oil pump 8 is stopped. Vacuum pipe 16 is closed, and vent valve on vent pipe 17 is opened to depressurize collection tank 7 to atmospheric pressure.
[0043] The collection tank 7 continues with the following operation: The discharge valve of the discharge pipe 18 is opened, and the liquid in the collection tank 7 flows out through the discharge pipe 18 and then through the Y-type filter 9, yielding clean and clear plant essential oil after filtration and impurity removal. After the plant essential oil in the collection tank 7 has finished discharging, the collection drain valve at the conical bottom of the collection tank 7 is opened, and the remaining liquid and a small amount of impurities in the collection tank 7 can be completely drained through the drain pipe.
[0044] Similarly, in the first step, the filtration drain valve at the bottom of the filtration tank 1 is opened, which can completely drain the residual liquid in the filtration tank 1 and the filtrate pipe 13, thereby completing all filtration and impurity removal operations.
[0045] The complete set of equipment mainly includes a collection tank 7, a filtration tank 1, and a vacuum oil pump 8. The three main pieces of equipment are fixed on a hand-pushed flatbed cart 10 by the support bracket of the filtration tank 1 (20 in the figure) and the support bracket of the collection tank 7 (21 in the figure). They can be moved to any place where filtration is needed to perform impurity removal operations.
[0046] After the plant essential oil containing impurities is filtered through filter paper, the impurities are blocked on the filter paper under vacuum. The filtered plant essential oil is stored in the collection tank 7. After reaching a certain liquid level, it is filtered through the two Y-type filters 9 on the discharge pipe 18 on the side of the cone bottom of the collection tank 7 and discharged. This process can completely remove trace impurities from the plant essential oil, resulting in a clear and transparent plant essential oil that meets the required specifications, ensures the cleanliness of the product, improves production filtration efficiency, and significantly reduces production costs.
[0047] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
