Abstract
Description
Technical Field
[0001] This utility model provides a silicone oil purification and refining device, belonging to the field of silicone oil treatment technology. Background Technology
[0002] Silicone oil typically refers to linear polysiloxane products that remain liquid at room temperature. Due to their high temperature resistance, low viscosity, good electrical insulation, and lubrication properties, they provide excellent protection and enhancement functions and are widely used in lubricants, cosmetics, electronics, medical devices, and other fields.
[0003] Impurities in crude silicone oil, such as metal ions and small organic molecules, can easily affect its performance during use. To improve the chemical stability and performance of silicone oil, purification equipment is usually required. Existing technology typically uses molecular sieves as the purification medium for silicone oil. Molecular sieves have a uniform microporous structure, and the size of these micropores is comparable to the size of some small molecule impurities. They can adsorb impurities such as water, small organic molecules, and metal ions in the silicone oil into the micropores through physical adsorption.
[0004] However, when the molecular sieve continues to work, the micropores will gradually be filled with adsorbate, reaching adsorption saturation. Therefore, the molecular sieve needs to be replaced. When replacing the molecular sieve, the purification process often needs to be paused, all the silicone oil in the purification device needs to be released, and then the molecular sieve needs to be removed, replaced with a new one, and purification can continue. This operation is relatively cumbersome and not conducive to the continuous purification of silicone oil. Utility Model Content
[0005] The technical problem this invention aims to solve is that replacing molecular sieves is cumbersome and not conducive to the continuous purification of silicone oil.

Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings.
[0021] according to Figure 1-4 As shown: This utility model provides a silicone oil purification and refining device: including a workbench 1, on which a bracket 2 is fixedly connected; an oil inlet pipe 3 and a feed pipe 4 are provided on the bracket 2, and a purification cylinder 5 is provided inside the bracket 2, with an inlet hole 14 opened above the purification cylinder 5, and a screw plug is threadedly connected inside the inlet hole 14.
[0022] There are two purification cylinders 5, one of which corresponds to the oil inlet pipe 3 and the other corresponds to the feed pipe 4; a rotating component is installed inside the bracket 2, and the two purification cylinders 5 are fixedly connected to the rotating component.
[0023] like Figure 2 As shown, the rotating assembly includes a rotating motor 12 and a rotating shaft 11. The rotating motor 12 is mounted on a bracket 2, and the rotating shaft 11 is located inside the bracket 2 and is fixedly connected to the output shaft of the rotating motor 12. A connecting rod 13 is fixedly connected to the purification cylinder 5, and the purification cylinder 5 is fixedly connected to the rotating shaft 11 through the connecting rod 13. The two purification cylinders 5 are arranged at 180° intervals. By setting the rotating motor 12 and the rotating shaft 11, the rotation of the two purification cylinders 5 can be easily controlled.
[0024] A filter screen 18 is installed inside the purification cylinder 5, and a sealing plug 16 is installed at the bottom of the purification cylinder 5, with the filter screen 18 and the sealing plug 16 fixedly connected; for example Figure 3 , 4 As shown, the sealing plug 16 is threaded to the bottom of the purification cylinder 5, and a connecting post 19 is fixedly connected to the sealing plug 16. The filter screen 18 is fixedly connected to the sealing plug 16 through the connecting post 19. The filter screen 18 can filter the molecular sieve during oil discharge, preventing the molecular sieve from flowing out with the silicone oil. At the same time, the fixed connection between the sealing plug 16 and the filter screen 18 allows the filter screen 18 to be installed or removed synchronously with the sealing plug 16, improving the efficiency of removing and replacing the molecular sieve.
[0025] like Figure 3 , 4As shown, the sealing plug 16 is provided with an oil outlet pipe 17 that communicates with the purification cylinder 5. The oil outlet pipe 17 is provided with a valve, and the inner wall of the purification cylinder 5 is fixedly provided with an annular limiting plate 15 that fits against the filter screen 18. The workbench 1 is provided with a receiving groove 9, and the oil outlet pipe 17 is located above the receiving groove 9. The receiving groove 9 can store the silicone oil flowing out of the oil outlet pipe 17, and the receiving groove 9 is connected to an outlet pipe 10.
[0026] A support plate 8 is fixedly installed on one side of the workbench 1, and a receiving component is installed on the support plate 8. For example... Figure 1 As shown, the receiving assembly includes an electric telescopic rod 7 and a receiving box 6; the electric telescopic rod 7 is fixedly mounted on the support plate 8, and the receiving box 6 is fixedly connected to the working end of the electric telescopic rod 7. By setting the receiving box 6, which is controlled by the electric telescopic rod 7, the sliding control of the receiving box 6 can be conveniently achieved, thereby receiving the extracted molecular sieve.
[0027] The principle of this utility model
[0028] like Figure 1 , 2 As shown, when using this invention, for the two purification cylinders 5, each containing molecular sieves; open the purification cylinder 5 corresponding to the oil inlet pipe 3, and add silicone oil into the purification cylinder 5 through the oil inlet pipe 3; start the rotating motor 12 to drive the purification cylinder 5 to rotate, thereby accelerating the mixing of molecular sieves and silicone oil in the purification cylinder 5. When purification is complete, open the valve on the oil outlet pipe 17 to allow the silicone oil in the purification cylinder 5 to flow into the receiving trough 9. Then close the valve, open the screw plug, and add silicone oil into the purification cylinder 5 again through the oil inlet pipe 3 to ensure continuous purification of the silicone oil.
[0029] When it is necessary to replace the molecular sieve inside purification cartridge 5, such as Figure 3 , 4 As shown, first, open the valve on the oil outlet pipe 17 to drain the silicone oil from the currently used purification cylinder 5. Then, start the rotating motor 12 to rotate both purification cylinders 5, positioning the new purification cylinder 5 in the position corresponding to the oil inlet pipe 3, while the old purification cylinder 5 is positioned near the receiving box 6. Open the screw plug and add silicone oil into the new purification cylinder 5 through the oil inlet pipe 3 to ensure continuous silicone oil purification. For the old, replaced purification cylinder 5, first activate the electric telescopic rod 7 to slide the receiving box 6 below the purification cylinder 5, unscrew the sealing plug 16, and remove the filter screen 18 along with it, allowing the molecular sieve inside the purification cylinder 5 to fall into the receiving box 6, thus completing the removal of the molecular sieve. Then, add a new molecular sieve into the purification cylinder 5 through the feed pipe 4. Finally, seal both purification cylinders 5 again and then proceed with normal purification. Therefore, this application can remove and replace the molecular sieve in the old purification cylinder 5 while adding new silicone oil, improving the continuous working efficiency of silicone oil purification.

In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
