[0023] Please see Figure 1-3 This utility model provides a technical solution: a filtration device for silicone oil production, comprising a tank 1, a filter tube 2 and a conical filter plate 3;

[0024] The top of the tank body 1 is provided with an upper cover 4, and the bottom of the tank body 1 is provided with a lower cover 5. The upper cover 4 and the lower cover 5 are respectively connected to the two ends of the tank body 1 through flanges to facilitate the connection and disassembly of the upper cover 4 and the lower cover 5 to the tank body 1.

One open end of the filter tube 2 is connected to the bottom end of the extension connecting pipe 8 through a flange, so as to facilitate the connection and disassembly of the filter tube 2 and the extension connecting pipe 8. The wall of the filter tube 2 is densely covered with sieve holes. The silicone oil is filtered for the first time through the sieve holes of the filter tube 2.

[0026] Furthermore, the cover plate at the lower end of the filter tube 2 is also provided with sieve holes.

[0027] The conical filter plate 3 is installed inside the tank 1 and located below the filter tube 2. An annular connecting plate 11 is provided on the upper part of the conical filter plate 3. The annular connecting plate 11 is fastened to the inner wall of the tank 1 by bolts. The connection and disassembly with the tank 1 are realized through the annular connecting plate 11. The conical filter plate 3 is densely covered with sieve holes. The silicone oil is filtered a second time through the sieve holes of the conical filter plate 3.

[0028] Installation Method and Operating Principle: First, the following components are manufactured: tank body 1, upper cover 4, lower cover 5, filter tube 2, conical filter plate 3, and transparent arc-shaped plate 9. An extension connecting pipe 8 is welded to the inside of the upper cover 4, located on the extension section of the feed inlet 6. The transparent arc-shaped plate 9 can be made of transparent materials such as stainless steel, glass, or acrylic. During assembly, first, the conical filter plate 3 is installed inside the lower end of the tank body 1 using an annular connecting plate 11 and bolts. Then, the upper cover 4 and lower cover 5 are securely connected to both ends of the tank body 1 using flanges and bolts / nuts. Next, the filter tube 2 is placed into the tank body 1 through the through-slot, and the open end of the filter tube 2 is securely connected to the bottom of the extension connecting pipe 8 using flanges and bolts / nuts. Finally, the transparent arc-shaped plate 9 is installed in the through-slot of the tank body 1 using bolts, completing the installation. Before use, connect the feed port 6 of the upper cover 4 to the silicone oil delivery pipeline, and connect the discharge port 7 of the lower cover 5 to the silicone oil discharge pipeline. The silicone oil enters the filter tube 2 through the feed port 6 and the extension connecting pipe 8. After preliminary filtration through the sieve holes of the filter tube 2, most impurities will remain in the filter tube 2. The silicone oil flows from the sieve holes to the conical filter plate 3, and the remaining impurities are filtered through the conical filter plate 3. Then, the silicone oil flows into the lower cover 5 through the sieve holes of the conical filter plate 3 and flows out from the discharge port 7 of the lower cover 5, completing the secondary filtration. When it is necessary to clean the impurities, open the transparent arc plate 9 and separate the filter tube 2 and the extension connecting pipe 8 to clean the impurities in the filter tube 2. The impurities on the conical filter plate 3 can be removed by external extraction equipment. This utility model has a reasonable structure. The tank body 1 is equipped with a filter tube 2 and a conical filter plate 3. The secondary filtration greatly improves the filtration effect of silicone oil impurities. The open end of the filter tube 2 is detachably connected to the extension connecting pipe 8 inside the top cover 4, which can realize the disassembly of the filter tube 2. The tank body 1 is provided with a through groove to facilitate the removal of the filter tube 2, thereby facilitating the cleaning of impurities concentrated in the filter tube 2. At the same time, a transparent arc plate 9 is provided at the through groove of the tank body 1, so as to facilitate the observation of the silicone oil filtration inside the tank body 1 and the condition of impurities on the conical filter plate 3.
