Description

Technical Field

[0001] This utility model relates to the field of essential oil extraction, and in particular to an improvement of a device for filtering and purifying tangerine peel essential oil. Background Technology

[0002] Currently, after the extraction of tangerine peel essential oil, sedimentation is generally used to remove residual fruit peel and pectin. This extraction method requires a long settling time. Filtration can also be used. Filtration typically involves using a filter screen; however, it has been found that because tangerine peel powder is used in the extraction, the filter screen's pores often become clogged with tangerine peel powder and pectin after a short filtration time, affecting filtration efficiency and increasing the filtration time for tangerine peel essential oil. A common solution is to perform multiple filtrations with varying degrees of precision to purify the tangerine peel essential oil. However, this filtration method is inefficient and time-consuming. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a device for filtering and purifying tangerine peel essential oil.

[0004] This utility model is achieved using the following technical solution: a tangerine peel essential oil filtration and purification device, comprising a filter tank, the filter tank being divided into an upper tank and a lower tank by a partition, a filtrate outlet being provided on the partition, the filtrate outlet being connected to the upper tank and the lower tank, the upper tank being provided with a filter assembly and a scraping assembly, the edge of the filter assembly being fixed to the inner wall of the upper tank, the scraping assembly being in contact with the filter assembly and the scraping assembly rotating, causing the edge of the scraping assembly to scrape the filter assembly;

[0005] A negative pressure hole is provided on the side wall of the lower tank. The negative pressure hole is connected to the negative pressure component through a pipe. When the negative pressure component is activated, the lower tank forms a negative pressure.

[0006] The filter assembly includes a frame and a filter membrane. The edge of the filter membrane is fixed to the inner wall of the upper container by the frame. The upper part of the filter membrane is used to place the essential oil concentrate. The edge of the scraping assembly abuts against the surface of the filter membrane.

[0007] The scraping assembly includes a scraping shaft that extends along the axial direction of the upper tank and contacts the filter membrane. A scraping element is sleeved on the scraping shaft, and the scraping element rotates with the scraping shaft, with the edge of the scraping element contacting the filter membrane.

[0008] The scraping component includes a pair of scraping rods, which are fixedly connected to the scraping shaft and extend toward the inner wall of the upper tank. A scraping strip is provided on the side of the scraping rod that contacts the filter membrane.

[0009] The frame includes a pressure plate, and an annular platform is provided on the inner wall of the upper tank. The edge of the filter membrane is placed on the annular platform, and the pressure plate abuts against the filter membrane and is fixed to the annular platform.

[0010] The scraping assembly also includes a push pin. The scraping shaft is hollow inside and has an opening at the bottom for inserting the push pin. One end of the push pin, which is located inside the scraping shaft, is equipped with a push motor. The push motor pushes the push pin to press against the filter membrane.

[0011] An absorption hole is formed on the end face of the pin that contacts the filter membrane. The pin is hollow inside, and one end of the pin placed inside the scraping shaft is connected to the suction device through a flexible tube.

[0012] Compared to existing technologies, this invention uses negative pressure to draw the essential oil concentrate into the lower tank, forcing it through the filter membrane and separating the filter residue from the filtrate. In practical use, the pressure difference forces the essential oil concentrate through the filter membrane, further improving its precision. If the filter membrane pores become clogged, a scraping assembly can be activated to scrape away the deposits on the membrane surface. During scraping, a pin extends, creating a low point in the center of the membrane. As the scraping process continues, the deposits converge towards the center and are ultimately drawn out by the pin, achieving cleaning and extending the membrane's lifespan.

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0016] Reference Figure 1A device for filtering and purifying tangerine peel essential oil includes a filter tank 1, which is divided into an upper tank 11 and a lower tank 12 by a partition 13. A filtrate outlet 14 is provided on the partition 13, connecting the upper tank 11 and the lower tank 12. The upper tank 11 contains a filter assembly 2 and a scraping assembly 3. The edge of the filter assembly 2 is fixed to the inner wall of the upper tank 11. The scraping assembly 3 contacts the filter assembly 2 and rotates, causing its edge to scrape the filter assembly 2. A negative pressure hole 4 is provided on the side wall of the lower tank 12, and the negative pressure hole 4 is connected to a negative pressure assembly through a pipe. When the negative pressure assembly is activated, a negative pressure is created in the lower tank 12. When the essential oil concentrate is poured into the upper tank 11, the concentrate will remain on the filter assembly 2. At this time, the negative pressure assembly is activated, creating a negative pressure environment below the concentrate. When the pressure difference is sufficient, the concentrate can pass through the filter assembly 2, thus separating the clear essential oil from the concentrate. This forms a filtrate, which flows from the filtrate outlet 14 into the lower tank 12 to achieve solid-liquid separation and filtration purification. In this embodiment, because air pressure difference is used for filtration, the filtration accuracy of the filter assembly 2 can be increased, thereby reducing the number of filtration cycles and improving filtration purification efficiency.

[0017] In this embodiment, the filter assembly 2 includes a frame 21 and a filter membrane 22. The edge of the filter membrane 22 is fixed to the inner wall of the upper tank 11 through the frame 21. The upper part of the filter membrane 22 is used to place the essential oil concentrate. The edge of the scraping assembly 3 abuts against the surface of the filter membrane 22. The scraping assembly 3 includes a scraping shaft 31, which extends along the axial direction of the upper tank 11 and contacts the filter membrane 22. A scraping element 32 is sleeved on the scraping shaft 31. The scraping element 32 rotates with the scraping shaft 31, and the edge of the scraping element 32 contacts the filter membrane 22. The scraping shaft 31 extends upwards beyond the upper tank 11, so that the top of the upper tank 11 can be sealed with a cap. The scraping shaft 31 extends out of the cap and is driven to rotate by a motor fixed to the cap. In this embodiment, the scraping component 32 includes a pair of scraping rods 321, which are fixedly connected to the scraping shaft 31 and extend towards the inner wall of the upper tank 11. A scraping strip 322 is provided on the side of the scraping rod 321 that contacts the filter membrane 22. During use, residue adhering to the filter membrane 22 can be scraped and collected as the scraping rod 321 rotates. In this embodiment, the filter membrane 22 can be pressed and fixed to the inner wall of the upper tank 11 by the frame 21. Specifically, the frame 21 includes a pressure plate 211, and an annular platform 212 is provided on the inner wall of the upper tank 11. The edge of the filter membrane 22 is placed on the annular platform 212, and the pressure plate 211 abuts against the filter membrane 22 and is fixed to the annular platform 212. The pressure plate 211 presses the filter membrane 22, allowing the filter membrane 22 to be tensioned.

[0018] In this embodiment, the scraping assembly 3 also includes a push pin 33. The scraping shaft 31 is hollow inside, and an opening is formed at the bottom of the scraping shaft 31 for inserting the push pin 33. One end of the push pin 33, which is placed inside the scraping shaft 31, is equipped with a push motor 34. The push motor 34 pushes the push pin 33 to press against the filter membrane 22. An absorption hole 35 is opened on the end face of the push pin 33 that contacts the filter membrane 22. The hollow end of the push pin 33, which is placed inside the scraping shaft 31, is connected to a suction device through a hose 5. When the push pin 33 extends and presses against the filter membrane 22, the filter membrane 22 forms a centrally concave shape. At this time, the residue attached to the filter membrane 22 can gather towards the center and concentrate around the push pin 33, so that the push pin 33 can suck it up and clean it. That is, during the scraping process, the push pin 33 extends, making the filter membrane 22 form a central low point. During the scraping process, the sediment gathers towards the center of the filter membrane 22 and is finally sucked out by the push pin 33, achieving the purpose of cleaning and extending the service life of the filter membrane 22.

[0019] Compared to existing technologies, this invention uses negative pressure to draw the essential oil concentrate into the lower tank 12, allowing it to pass through the filter membrane 22 and separating the filter residue from the filtrate. In practical use, the pressure difference forces the essential oil concentrate through the filter membrane 22, further improving the filter membrane's precision. If the filter pores of the membrane 22 become clogged, the scraping component 3 can be activated to scrape away the sediment on the membrane 22's surface. During scraping, the ejector pin 33 extends, creating a low point in the center of the membrane 22. The sediment converges towards the center of the membrane and is eventually drawn out by the ejector pin 33, achieving cleaning and extending the membrane's lifespan. Simultaneously, when the essential oil concentrate is poured into the upper tank 11, it remains on the filter component 2. At this time, the negative pressure component is activated, creating a negative pressure environment below the concentrate. When the pressure difference is sufficient, the concentrate can pass through the filter component 2, separating the clear essential oil from the concentrate. In this embodiment, since air pressure difference is used for filtration, the filtration accuracy of the filter component 2 can be increased, thereby reducing the number of filtrations and improving the filtration and purification efficiency.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
