DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] Referring to Figures 1 to 3 An embodiment provided by the present application: a novel silicone oil purification equipment, comprising a purification cylinder 1, which provides a closed space environment for the silicone oil purification process. A top cover 2 is detachably connected to the top of the purification cylinder 1, which facilitates the installation, maintenance, and cleaning and replacement of internal components of the equipment. A motor 3 is fixedly connected to the top of the top cover 2, which provides stable power for the entire stirring mechanism. A feed cylinder 16 is fixedly connected to the top of the top cover 2, which facilitates the pouring of raw materials into the interior of the purification cylinder 1 by the staff. A transmission column 4 is fixedly connected to the driving end of the motor 3, which is used to transmit the power of the motor 3. The outer wall of the transmission column 4 is rotatably connected to the interior of the top cover 2, so that the transmission column 4 can stably rotate. A purification mechanism is fixedly connected to the inner wall of the purification cylinder 1, and a sealing mechanism is detachably connected to the exterior of the top cover 2;

[0034] The purification mechanism comprises a filter plate 7, which is used to separate large-particle impurities in the silicone oil, preventing them from entering the subsequent process to cause wear or affect the purification effect of the equipment. The outer wall of the filter plate 7 is fixedly connected to the inner wall of the purification cylinder 1, so that the filter plate 7 can be fixed at a specified position for preliminary filtration. The outer wall of the transmission column 4 is rotatably connected to the interior of the filter plate 7. An adsorption layer 8 is fixedly connected to the top of the filter plate 7, which utilizes its own adsorption properties, such as a porous structure or special chemical adsorption groups, to adsorb small impurity molecules, pigments, and other organic or inorganic impurities in the silicone oil, thereby reducing the impurity content in the silicone oil and improving the purity of the silicone oil.

[0035] The outer wall of the transmission column 4 is fixedly connected with a stirrer one 5, and the outer wall of the transmission column 4 is fixedly connected with a stirrer two 6. The stirrer one 5 is arranged at the top of the filter plate 7, and the stirrer two 6 is arranged at the bottom of the filter plate 7. When the transmission column 4 rotates, the stirrer one 5 and the stirrer two 6 rotate synchronously. The stirrer one 5 stirs the silicon oil which enters the purification cylinder 1 and is filtered preliminarily, so that the silicon oil fully contacts with the adsorption layer 8, and the adsorption efficiency is improved. The stirrer two 6 stirs the silicon oil which is filtered by the filter plate 7, so that the silicon oil is prevented from being deposited at the bottom of the purification cylinder 1 or from having a local concentration unevenness, and the physical and chemical properties of the silicon oil in the whole purification cylinder 1 are uniformly and stably ensured. The bottom of the purification cylinder 1 is provided with a heater 9. The heater 9 is used for providing stable heat so that the silicon oil at the bottom and volatile impurities are gasified, and subsequent collection operation is facilitated. The outer wall of the purification cylinder 1 is fixedly connected with a discharge pipe 10. The discharge pipe 10 transports the gas mixture (including silicon oil vapor and impurity vapor) which is volatilized after being heated in the purification cylinder 1 to a subsequent structure. The other end of the discharge pipe 10 is fixedly connected with a collection assembly.

[0036] The collection assembly comprises a condensing shunt pipe 11. The condensing shunt pipe 11 is fixedly connected to the other end of the discharge pipe 10. The condensing shunt pipe 11 is externally provided with a cold water circulation system. When the gas mixture enters the condensing shunt pipe 11, the temperature is reduced under the cooling action, and the silicon oil vapor and the impurity vapor begin to change phase and gradually condense into liquid. Since the boiling point of the silicon oil is higher than that of the impurities, the silicon oil is first condensed and liquefied by controlling the cooling temperature, and falls downward by gravity, so as to realize the separation of the silicon oil vapor and the impurity vapor. The bottom of the condensing shunt pipe 11 is threadedly connected with a silicon oil collection bottle 12. The silicon oil collection bottle 12 is used for collecting the purified silicon oil, so as to ensure the purity and quality stability of the silicon oil in the collection process, and the threadedly connected manner ensures the sealing property and convenient disassembly and assembly function of the whole collection structure.

[0037] The top of the condensing shunt pipe 11 is fixedly connected with a sealing ring 13. The sealing ring 13 ensures the sealing property of the whole collection assembly, and avoids problems such as reduction of purification efficiency or environmental pollution caused by leakage. The top of the condensing shunt pipe 11 is fixedly connected with a transportation pipe 14. The other end of the transportation pipe 14 is threadedly connected with an impurity collection cylinder 15. The arrangement of the transportation pipe 14 and the impurity collection cylinder 15 realizes effective collection of the impurities, prevents the impurities from being mixed into the silicon oil again, and facilitates subsequent treatment of the impurities, so as to maintain the cleanliness and normal operation of the equipment.

[0038] Referring to Figure 1 , Figure 2 , Figure 4The sealing mechanism comprises a plurality of fastening blocks 18, the outer wall of the plurality of fastening blocks 18 is detachably connected to the outer wall of the top cover 2, the plurality of fastening blocks 18 are deformable, the fastening blocks 18 clamp the top cover 2 and the purification cylinder 1 through the deformation of the fastening blocks 18, so as to ensure the sealing between the entire top cover 2 and the purification cylinder 1, so as to prevent environmental problems and safety problems caused by gas leakage. The fastening blocks 18 are internally screwed with screws 19, the outer sides of the plurality of screws 19 are externally screwed to the inside of the top cover 2, the outer sides of the plurality of screws 19 are externally screwed to the top of the purification cylinder 1, the screws 19 pass through the inside of the fastening blocks 18 and are screwed to the top cover 2 and the top of the purification cylinder 1, so that when the screws 19 are rotated, the fastening blocks 18 are deformed to seal the top cover 2 and the purification cylinder 1. The bottom of the screw 19 is externally screwed with a nut 20, the top outer wall of the nut 20 is in contact with the bottom outer wall of the fastening block 18, when the screw 19 is rotated, the nut 20 moves upward to extrude the fastening block 18, so that the fastening block 18 is deformed.

[0039] The bottom of the top cover 2 is fixedly connected with a rubber ring 17, the top of the purification cylinder 1 is provided with a mounting groove, the outer wall of the rubber ring 17 is detachably connected to the inside of the mounting groove, the rubber ring 17 has good elasticity and sealing performance, when the top cover 2 and the purification cylinder 1 are sealedly connected through the fastening blocks 18, the rubber ring 17 is deformed by being extruded in the mounting groove, filling the small gap between the top cover 2 and the purification cylinder 1, further enhancing the sealing effect.

[0040] Working principle: during installation, first place the top cover 2 on the top of the purification cylinder 1 at a suitable position, then put the fastening blocks 18 on the outer wall of the top cover 2, and screw in the screws 19, as the screws 19 are screwed in, the fastening blocks 18 are deformed by being extruded, so as to be tightly attached between the outer walls of the top cover 2 and the purification cylinder 1, generating sufficient friction and extrusion force, realizing the sealing connection of the top cover 2 and the purification cylinder 1, and when the top cover 2 and the purification cylinder 1 are sealedly connected through the fastening blocks 18, the rubber ring 17 is deformed by being extruded in the mounting groove, filling the small gap between the top cover 2 and the purification cylinder 1, thereby further enhancing the sealing effect.

[0041] Pouring raw material into the feeding cylinder 16, the raw material enters the inside of the purification cylinder 1 through the feeding cylinder 16, opening the motor 3, the motor 3 operates to drive the transmission column 4 to rotate, thereby driving the stirrer one 5 and the stirrer two 6 to rotate, the raw material contacts the filter plate 7 and the adsorption layer 8 through the action of the stirrer one 5, thereby the filter plate 7 can play a preliminary interception filtering effect on the larger particle impurities in the silicone oil, and then the adsorption layer 8 itself has the adsorption characteristics, such as the porous structure or special chemical adsorption group, etc., to adsorb the small impurity molecules, pigments and other organic or inorganic impurities in the silicone oil. In this way, the impurities in the silicone oil are preliminarily filtered and treated, and the filtered silicone oil enters the bottom of the purification cylinder 1, opening the heater 9, the heater 9 operates to increase the temperature in the purification cylinder 1, so that the silicone oil and the impurities in the silicone oil are gasified, and in the gas with temperature gradient, the gas molecules in the higher temperature part have higher kinetic energy, which will collide with the gas molecules in the lower temperature part, causing the particles to move from the high temperature part to the low temperature part, so that the silicone oil vapor and the impurity vapor enter the condensing shunt pipe 11 through the exhaust pipe 10, and then the temperature of the condensing shunt pipe 11 is controlled, so that the silicone oil is first liquefied and falls into the silicone oil collection bottle 12, while the impurity vapor is transported to the impurity collection cylinder 15 through the transport pipe 14 for liquefaction, so as to realize the complete separation of the silicone oil and the impurities.

[0042] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
