Description

Technical Field

[0001] This utility model relates to the field of chemistry, and in particular to silicone oil storage tank technology, specifically a vertical storage tank for silicone oil. Background Technology

[0002] Silicone oil is a polysiloxane formed by alternating silicon and oxygen elements, possessing a silicon-oxygen bond (Si-O) chain structure. It typically exists in a liquid or gel state and exhibits excellent chemical stability and high-temperature resistance. Silicone oil is widely used in lubricants, cosmetics, electronics, medical devices, textiles, leather, food processing, automobiles, optical equipment, aerospace, and coatings, providing excellent protection and enhancement functions due to its high-temperature resistance, low viscosity, good electrical insulation, and lubrication properties.

[0003] Silicone oil storage tanks are equipped with wall-scraping components to address the issue of silicone oil adhering to the tank walls and prevent waste. However, because the scraper in the wall-scraping component is connected to the agitator or shares a common shaft, after a period of use, whether due to friction or decreased agitator stability, the scraper may fail to fully contact the tank's inner wall. Replacing the scraper increases operating costs. Therefore, an improved technology is urgently needed to solve the aforementioned problems in the existing technology. Utility Model Content

[0028] The stirring mechanism includes a connecting cylinder 10, a stirring perforated plate 11, and a scraper 12. The outer wall of the connecting cylinder 10 is provided with a number of radial stirring perforated plates 11 at intervals along the circumference. The stirring perforated plates 11 are densely covered with through holes to facilitate better stirring of silicone oil, prevent stratification, and ensure uniform heating. The connecting cylinder 10 is inserted into the bottom of the main shaft 4 and fastened with bolts. A support rod 13 is connected between adjacent stirring perforated plates 11. A scraper 12 is connected to the outer end of each stirring perforated plate 11. The outer edge of the scraper 12 is movably connected to the inner wall of the tank 1.

[0029] The scraper 12 has a groove 22 on its inner side, and the stirring plate 11 is inserted into the groove 22 along its outer edge. The scraper 12 has several waist holes 23 on both sides of the groove 22, and the stirring plate 11 has a connecting hole 24 at its outer end. The connecting hole 24 corresponds to the waist hole 23 and is connected by bolts and nuts. This structure makes it easy to adjust the position of the scraper 12, ensures that it can make smooth contact with the inner wall of the tank 1, and facilitates the replacement of the scraper 12.

[0030] Installation method and operating principle: Weld multiple vertical plates 7 with heat exchange medium flow channels 8 to the inside of the jacket 6. Then, fit the jacket 6 onto the outside of the tank body 1, and weld the jacket 6 to the outer wall of the tank body 1. At this time, the inner edge of the vertical plate 7 is supported by the outer wall of the tank body 1. Weld the bottom plate 9 to the bottom of the tank body 1, and then pass the discharge port 14 through the jacket 6 and weld it to the tank body 1 and the jacket 6. Insert the connecting cylinder 10 with multiple stirring orifice plates 11 into the bottom end of the main shaft 4 and fasten it with bolts. Weld support rods 13 between adjacent stirring orifice plates 11 to ensure the stability and structural strength of each stirring orifice plate 11. Install the motor 3 on the motor base 5, and connect the main shaft 4 to the output shaft of the motor 3 through a coupling. Then, lift the tank cover 2 and place the stirring orifice plates 11 and the main shaft 4 into the tank body 1, while supporting the bottom of the main shaft 4 on the shaft seat 25 of the bottom plate 9. Then, weld the tank cover 2 to the tank body 1. The installer enters the tank 1 through manhole 19, inserts the groove 22 of scraper 12 into the outer edge of the stirring orifice plate 11, aligns the connecting hole 24 of the stirring orifice plate 11 with the waist hole 23 of scraper 12, and connects them using bolts and nuts. During the tightening of bolts and nuts, the outer edge of scraper 12 is pressed against the inner wall of tank 1, and finally, the installation is completed by tightening the bolts and nuts. In use, silicone oil is introduced into tank 1 through inlet 20, and nitrogen is introduced into tank 1 through nitrogen inlet 21. A thermometer is installed at thermometer port 15, a pressure gauge is installed at pressure gauge port 16, a non-contact level gauge (such as a radar / ultrasonic level gauge) is installed at level gauge port 17, a breather valve is installed at breather port 18, and nitrogen inlet 21 is connected to a nitrogen storage tank through a pipeline. During the storage of silicone oil, when the temperature is too low, hot oil, hot water or steam is poured into the jacket 6, and the motor 3 is started periodically. The motor 3 drives each stirring plate 11 to rotate through the main shaft 4, thereby carrying out homogenization and stirring to ensure product consistency. This utility model has a reasonable structure. The agitator is composed of multiple agitator plates 11, and a support rod 13 connects adjacent agitator plates 11. A scraper 12 is provided on the outer edge of the agitator plate 11. The scraper 12 can scrape off the silicone oil adhering to the inner wall of the tank 1 during discharge, avoiding waste. The support rod 13 ensures the stability and structural strength of each agitator plate 11, thereby ensuring the stability of the scraper 12 and preventing the scraping effect from being affected by the instability of the agitator plate 11. The scraper 12 cooperates with the connecting hole 24 of the agitator plate 11 through the waist hole 23, so as to facilitate the adjustment of the position of the scraper 12 and avoid the situation that the scraper 12 cannot be installed or cannot scrape the wall due to processing errors. Several vertical plates 7 with heat exchange medium flow grooves 8 are provided in the jacket 6, thereby improving the structural strength of the jacket 6 and preventing the deformation of the jacket 6.
