With its high temperature resistance, lubrication, and hydrophobicity, it plays an important role in daily chemical, industrial, and pharmaceutical fields.

[0003] Vacuum separators are important equipment in silicone oil production. They utilize the differences in physical properties (such as boiling point, volatility, density, etc.) of different substances under vacuum conditions to achieve efficient separation. They are commonly used to separate impurities from silicone oil.

[0005] Vacuum separation tanks in the prior art, including those mentioned above, can meet general separation needs, but because silicone oil has high viscosity, it is easy to form local colloidal agglomerates, which makes it difficult to separate impurities (such as solid particles and oligomers) that are trapped inside.

[0006] To address the aforementioned problems, this invention proposes a self-cleaning high-vacuum silicone oil separation device. Utility Model Content

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figures 1-4 The present invention provides the following technical solution: a self-cleaning high vacuum silicone oil separation device, including a frame 1, a vacuum tank 2, a filter tray 9 fixed inside the vacuum tank 2, a sealing cover plate 4 fixed to the top of the vacuum tank 2, and an atomizer 5 fixed to the top of the sealing cover plate 4. One end of the atomizer 5 is provided with a liquid inlet 51, and the other end is provided with a liquid outlet 52 communicating with the internal environment of the vacuum tank 2. The device further includes a flipping power mechanism 3 and a stirring mechanism 6.

[0043] Furthermore, by Figure 1 As shown in this embodiment, the vacuum tank 2 is rotatably mounted on the frame 1, the flipping power mechanism 3 is used to drive the vacuum tank 2 to flip, and the stirring mechanism 6 is fixed on the sealing cover plate 4 and located directly above the filter tray 9. With the above scheme, when in use, the sealing cover plate 4 is closed to form a closed space inside the vacuum tank 2. The external vacuum pump draws the vacuum tank 2 to a predetermined vacuum degree through the air extraction port on the sealing cover plate 4. The high vacuum environment is used to reduce the boiling point of the silicone oil mixture, creating conditions for subsequent separation.

[0044] The impurity-containing silicone oil mixture to be separated is introduced through the liquid inlet 51 of the atomizer 5, and sprayed in a mist form from the liquid outlet 52 through the internal flow channel of the atomizer 5 into the vacuum tank 2.

[0045] Turn on the stirring mechanism 6 to evenly disperse the atomized silicone oil mixture. Due to density differences, impurity particles gradually settle to the surface of the filter tray 9, while the silicone oil liquid passes through the sieve holes of the filter tray 9 and gathers at the bottom of the tank. During this process, the shearing action of the stirring mechanism 6 can break the surface tension of the liquid and accelerate the movement and separation of the solid and liquid phases. At the same time, the uniform flow field distribution avoids local concentration differences and improves filtration efficiency.

[0046] During this process, the rotating power mechanism 3 is activated to drive the vacuum tank 2 to rotate back and forth around the rotating shaft of the frame 1. Combined with the stirring action of the stirring mechanism 6, the material is kept in a dynamic mixing state, which breaks down the agglomeration structure and makes it easier for impurities to be separated from the silicone oil, thereby improving the thoroughness of solid-liquid separation or component separation and increasing the purity of the target product.

[0047] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the tilting power mechanism 3 includes: two fixed shafts 31, a worm gear 32, two perforated mounting ears 33, a worm 34, and a primary drive motor 35. The two fixed shafts 31 are symmetrically fixed to the outer wall of the vacuum tank 2, and the fixed shafts 31 penetrate the frame 1 to form a rotating structure. The worm gear 32 is fixed on the fixed shafts 31. The two perforated mounting ears 33 are fixed at intervals to the outer wall of the frame 1. The worm 34 is rotatably mounted between the two perforated mounting ears 33 and meshes with the worm gear 32. The primary drive motor 35... Fixed to the outer wall of the perforated mounting ear 33, used to drive the worm gear 34 to rotate. With the above scheme, when in use, the first drive motor 35 is started to drive the worm gear 34 to rotate. Since the worm gear 34 is rotatably installed between the two perforated mounting ears 33 and meshes with the worm wheel 32, the worm gear 34 will drive the worm wheel 32 to rotate through the meshing action when it rotates. Since the worm wheel 32 is fixed on the fixed shaft 31, and the two fixed shafts 31 are symmetrically fixed to the outer wall of the vacuum tank 2, the worm wheel 32 will use the fixed shaft 31 to drive the vacuum tank 2 to rotate.

[0048] The vacuum tank 2 is driven by the No. 1 drive motor 35 to rotate back and forth within a suitable angle range, generating a vibration effect, so that the material is continuously in a dynamic mixing state, breaking the agglomeration structure and making it easier for impurities to be separated from the silicone oil.

[0049] Optionally, by Figure 1 and Figure 3 As shown, in this embodiment, the stirring mechanism 6 includes: a rotating column 61, multiple sets of stirring paddles 62, and a second drive motor 63. The rotating column 61 is rotatably mounted on the bottom surface of the sealing cover plate 4. The multiple sets of stirring paddles 62 are fixed at equal intervals along the circumferential direction on the outer wall of the rotating column 61. The second drive motor 63 is fixed on the top surface of the sealing cover plate 4 and is used to drive the rotating column 61 to rotate. With the above scheme, when in use, the second drive motor 63 is started to drive the rotating column 61 to rotate. The rotating column 61 drives the multiple sets of stirring paddles 62 to rotate in the filter tray 9 to stir the material. The shearing action of the stirring paddles 62 can break the surface tension of the liquid and accelerate the movement and separation of the solid and liquid phases. At the same time, the uniform flow field distribution avoids local concentration differences and improves filtration efficiency.

[0050] Preferably, by Figure 1 , Figure 3 and Figure 4As shown in this embodiment, the stirring mechanism 6 further includes: a vertical scraper 10 and a vertical rubber scraper 11. The vertical scraper 10 is fixed to the end of the stirring paddle 62, and the vertical rubber scraper 11 is fixed to the outer wall of the vertical scraper 10 and adheres to the inner wall of the filter tray 9. With the above solution, when the stirring paddle 62 rotates, it will synchronously drive the vertical scraper 10 to rotate. The vertical scraper 10 drives the vertical rubber scraper 11 to adhere to the inner wall of the filter tray 9 and make a circular motion, scraping off the silicone oil material adhering to the inner wall of the filter tray 9, realizing self-cleaning and reducing the cost of manual cleaning.

[0051] Preferably, by Figure 1 , Figure 3 and Figure 4 As shown in this embodiment, the stirring mechanism 6 further includes: a horizontal scraper 12 and a horizontal rubber scraper 13. The horizontal scraper 12 is fixed to the outer wall of the rotating column 61, and the horizontal rubber scraper 13 is fixed to the bottom surface of the horizontal scraper 12 and fits against the inner bottom surface of the filter tray 9. With the above solution, when the rotating column 61 is rotating, it will drive the horizontal scraper 12 to rotate synchronously. The horizontal scraper 12 drives the horizontal scraper 12 to make a circular motion against the inner bottom surface of the filter tray 9, which avoids impurities from sticking to the filter tray 9 and making it difficult to clean, thus achieving self-cleaning and reducing manual cleaning costs.

[0052] Preferably, by Figure 1 and Figure 3 As shown in this embodiment, the filter tray 9 is fixed to the vacuum tank 2 with bolts. With the above solution, the filter tray 9 is fixed with bolts during use, which not only ensures the installation stability of the filter tray 9, but also facilitates the disassembly, cleaning or replacement of the filter tray 9, reducing the cost of manual cleaning.

[0053] Preferably, by Figure 1 As shown, in this embodiment, it further includes: a plurality of wing bolts 7, which are evenly distributed along the circumference and are fixedly connected to the vacuum tank 2 by threaded engagement after passing through the sealing cover plate 4. With the above solution, the sealing cover plate 4 is fixed by a plurality of wing bolts 7 during use. While ensuring the installation stability of the sealing cover plate 4, it is also convenient to disassemble the sealing cover plate 4, which facilitates the cleaning and maintenance of the inner wall of the vacuum tank 2, and also facilitates the disassembly, cleaning or replacement of the filter tray 9.

[0054] Preferably, by Figure 1 As shown, in this embodiment, it further includes a handle 8, which is fixed to the top surface of the sealing cover plate 4. With the above solution, the sealing cover plate 4 can be easily moved by the handle 8 during use, which facilitates the installation and disassembly of the sealing cover plate 4.

[0055] It should be noted that the No. 1 drive motor 35, atomizer 5, and No. 2 drive motor 63 are all commercially available conventional devices with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.

[0056] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0057] Components not described in detail in this article are existing technologies.

[0058] The working principle and usage process of this utility model: When using the self-cleaning high vacuum silicone oil separation device of this utility model, the sealing cover plate 4 is closed to form a closed space inside the vacuum tank 2. The external vacuum pump draws the vacuum tank 2 to a predetermined vacuum degree through the air extraction port on the sealing cover plate 4. The high vacuum environment is used to reduce the boiling point of the silicone oil mixture, creating conditions for subsequent separation.

[0059] The impurity-containing silicone oil mixture to be separated is introduced through the liquid inlet 51 of the atomizer 5, and sprayed into the vacuum tank 2 in a mist form from the liquid outlet 52 through the internal flow channel of the atomizer 5.

[0060] Turn on the stirring mechanism 6 to evenly disperse the atomized silicone oil mixture. Due to the density difference, the impurity particles gradually settle to the surface of the filter tray 9, while the silicone oil liquid passes through the sieve holes of the filter tray 9 and gathers at the bottom of the tank. During this process, the shearing action of the stirring mechanism 6 can break the surface tension of the liquid and accelerate the movement and separation of the solid and liquid phases. At the same time, the uniform flow field distribution avoids local concentration differences and improves filtration efficiency.

[0061] During this period, the flipping power mechanism 3 is activated to drive the vacuum tank 2 to flip back and forth around the rotating shaft of the frame 1. Combined with the stirring action of the stirring mechanism 6, the material is kept in a dynamic mixing state, which breaks the agglomeration structure and makes it easier for impurities to be separated from the silicone oil, thereby improving the thoroughness of solid-liquid separation or component separation and improving the purity of the target product.

[0062] After separation, vacuum tank 2 is flipped to a vertical position. The silicone oil liquid is discharged from the outlet at the bottom of vacuum tank 2 (shown in the figure), and the vaporized liquid (connected to the exhaust fan) is discharged from the exhaust port at the top of vacuum tank 2 (shown in the figure).

[0063] The separation device of this utility model includes a frame 1, a vacuum tank 2, a filter tray 9, a sealing cover 4, and an atomizer 5. It also adds a flipping power mechanism 3 and a stirring mechanism 6. The combination of flipping and stirring improves the separation efficiency, breaks up the colloidal agglomerates, and allows impurities to be fully exposed and filtered. The scraper achieves self-cleaning of the inner wall and bottom surface of the filter tray 9, reducing manual cleaning costs.

[0064] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
