[0021] Please see Figure 1-2 This utility model provides a technical solution: an organosilicon oil filtration device, comprising a tank 1, a cylinder 2, activated carbon 3, a filter screen 4, and a filter membrane 5;

[0022] The bottom of the tank body 1 is provided with a conical discharge port 6, and the top of the tank body 1 is provided with a tank cover 7. The tank cover 7 is fastened to the top of the tank body 1 by bolts to realize the installation and removal of the tank cover 7, thereby realizing the replacement of activated carbon 3, filter screen 4 and filter membrane 5. The tank cover 7 is provided with a feed port 8. The upper part of the inner wall of the tank body 1 is provided with an annular boss 9. Several support seats 16 are provided on the outer periphery of the tank body 1 to realize the support and fixation of the tank body 1. The side wall of the tank body 1 is also provided with an observation port 17 to facilitate the observation of the filtration status inside the tank body 1.

[0023] A flange 10 is provided at the top of the cylinder 2. Several handles 15 are provided on the upper surface of the flange 10 to facilitate the removal and insertion of the cylinder 2. The cylinder 2 is coaxially arranged inside the tank 1. The flange 10 is supported on the upper surface of the annular boss 9 and is fastened with bolts. A bottom plate 11 is provided at the bottom of the cylinder 2. A perforated plate 12 is provided in the middle of the cylinder 2. A filter screen 4 is provided on the upper surface of the perforated plate 12. Activated carbon 3 is placed inside the cylinder 2 and supported on the filter screen 4. A circumferential groove 13 is opened on the outer wall of the cylinder 2 below the perforated plate 12. Several through grooves 14 are opened in the groove 13 of the cylinder 2. The membrane 5 is wrapped around the groove 13 of the cylinder 2. The bottom plate 11 is fastened to the bottom of the cylinder 2 by bolts to realize the installation and removal of the bottom plate 11. The outer diameter of the bottom plate 11 is larger than the outer diameter of the cylinder 2. The bottom plate 11 is used to ensure that the filter membrane 5 will not fall off. The upper surface of the bottom plate 11 is provided with a positioning boss 18. The positioning boss 18 is inserted into the bottom of the cylinder 2. The outer diameter of the positioning boss 18 is the same as the inner diameter of the cylinder 2. The horizontal height of the upper surface of the positioning boss 18 is not lower than the horizontal height of the bottom of the through groove 14. The positioning boss 18 is used to ensure that the silicone oil can flow smoothly out of the cylinder 2 from the through groove 14 after falling on the positioning boss 18.

[0024] Usage and Principle: Lay the filter screen 4 flat on the upper surface of the perforated plate 12 and secure it to the perforated plate 12 with bolts. Place the filter membrane 5 from bottom to top into the groove 13 at the bottom of the cylinder 2, and install the bottom plate 11 at the bottom of the cylinder 2 with bolts. At this time, the positioning boss 18 is inserted into the bottom of the cylinder 2. Then, place the activated carbon 3 inside the cylinder 2 and support it on the filter screen 4, which is supported by the perforated plate 12. Next, lift the cylinder 2 and place it into the tank 1, with the flange 10 at the top of the cylinder 2 supported on the annular boss 9 on the inner wall of the tank 1. Secure the flange 10 to the boss with bolts. Finally, put on the tank cover 7 and secure it to the tank 1 with bolts to complete the installation. During use, the silicone oil enters the cylinder 2 through the inlet 8. After being adsorbed by activated carbon 3, pigments, odor molecules and small organic molecules are removed, thus completing the decolorization and deodorization process. Then, it enters the filter screen 4 for initial filtration, and then enters the lower half of the cylinder 2. After passing through the channel 14 of the cylinder 2, it undergoes secondary filtration through the filter membrane 5, and finally exits from the conical outlet 6 at the bottom of the tank 1.

[0025] This utility model has a reasonable structure. A perforated plate 12 is installed inside the cylinder 2, and a filter screen 4 is installed on the upper surface of the perforated plate 12. The upper half of the cylinder 2 is filled with activated carbon 3, and the lower part of the cylinder 2 is wrapped with a filter membrane 5. The bottom is sealed by a base plate 11. Through the cooperation of the activated carbon 3, filter screen 4, and filter membrane 5, a single device can simultaneously filter pigments, odor molecules, small organic molecules, and small particles, reducing the footprint and investment cost. Furthermore, the activated carbon 3 and filter screen 4 are both located inside the cylinder 2, while the filter membrane 5 wraps around the outside of the cylinder 2. The cylinder 2 has a detachable structure, facilitating the replacement of the activated carbon 3, filter screen 4, and filter membrane 5.
