Description

Technical Field

[0001] This invention relates to the field of silicone oil production technology, and more specifically, to a production equipment and preparation method for silicone oil with low thermal conductivity. Background Technology

[0002] Low thermal conductivity silicone oil is a polyorganosiloxane liquid whose thermal conductivity is significantly reduced through molecular structure design or the addition of modified materials. The formation of low thermal conductivity silicone oil is inseparable from the reaction vessel, which is the core equipment for the silicone oil polymerization reaction and must withstand high temperature and pressure. Existing silicone oils require different internal structures in the reaction vessel when forming high-viscosity or low-viscosity states. This is because high-viscosity silicone oil has poor flowability; if a low-viscosity stirrer is used for mixing, it cannot provide sufficient shear force, easily resulting in low stirring efficiency.

[0013] A method for preparing a low thermal conductivity silicone oil, based on the production equipment for a low thermal conductivity silicone oil as described above, comprising the following steps: S1: If it is necessary to generate high viscosity silicone oil, firstly, the relevant raw materials and catalysts are put into the reactor body. The second adjustment component drives multiple baffles to rise vertically and move away from the mixture. Then, the first adjustment component drives the L-shaped stirring plates on both sides to align and be perpendicular to the horizontal plane of the mixture. Then, the stirring rod drives the L-shaped stirring plates on both sides to rotate synchronously at low speed to stir the high viscosity mixture and generate high viscosity silicone oil. S2: If low-viscosity silicone oil is to be generated, the relevant raw materials and catalysts are first put into the reactor body. The second adjustment component drives multiple baffles to descend vertically into the mixture at the same time. Then, the first adjustment component drives the L-shaped stirring plates on both sides to rotate at a preset angle. Then, the stirring rod drives the L-shaped stirring plates on both sides to rotate at high speed at the same time, stirring to generate low-viscosity silicone oil. Finally, the generation and stirring of silicone oil of different viscosities can be achieved by adjusting the structural state of the reactor body.

[0014] The beneficial effects of the low thermal conductivity silicone oil production equipment of the present invention are as follows: If high viscosity silicone oil is required, multiple baffles are driven to rise vertically synchronously and move away from the mixture by the second adjustment component. Then, the L-shaped stirring plates on both sides are aligned and perpendicular to the horizontal plane of the mixture by the first adjustment component. Then, the stirring rod drives the L-shaped stirring plates on both sides to rotate synchronously at low speed to stir the high viscosity mixture. If low viscosity silicone oil is required, multiple baffles are driven to descend vertically synchronously into the mixture by the second adjustment component. Then, the L-shaped stirring plates on both sides are driven to rotate synchronously away from the preset angle by the first adjustment component. Then, the stirring rod drives the L-shaped stirring plates on both sides to rotate synchronously at high speed. Since the blades of the L-shaped stirring plates on both sides are tilted at this time, the mixture is pushed axially to form a circulating flow that is drawn in from below the blades and discharged from above, realizing rapid mixing of the upper and lower layers. In addition, the baffles disrupt the tangential flow to ensure uniform stirring of the low viscosity mixture. Finally, the generation and stirring of silicone oil of different viscosities can be achieved by adjusting the internal structure of the reactor body. Attached Figure Description

Detailed Implementation

[0017] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] In the description of this specification, the references to terms such as "embodiment," "one embodiment," "some implementations," "exemplary," and "one implementation," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or implementation of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0020] The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0021] like Figure 1-8As shown, this embodiment of the invention provides a production device for low thermal conductivity silicone oil, including a reactor body 100, a stirring rod 104, an L-shaped stirring plate 305, a baffle plate 405, a first adjustment component, and a second adjustment component. The stirring rod 104 is disposed inside the reactor body 100 and is rotatable. The first adjustment component is disposed at the bottom end of the stirring rod 104. Two L-shaped stirring plates 305 are symmetrically disposed on both sides of the first adjustment component. The first adjustment component is used to drive the two L-shaped stirring plates 305 to rotate synchronously towards each other or synchronously away from each other in the vertical direction. The second adjustment component is disposed at the upper inner side of the reactor body 100. Multiple baffle plates 405 are evenly disposed on the inner wall of the reactor body 100. The second adjustment component is used to drive the multiple baffle plates 405 to rise and fall synchronously vertically.

[0022] In this embodiment, during the generation of low thermal conductivity silicone oil within the reactor body 100, if high viscosity silicone oil is required, the relevant raw materials and catalyst are first added into the reactor body 100. Then, the second adjusting component drives multiple baffles 405 to rise vertically and synchronously, so that the multiple baffles 405 rise vertically to a preset height on the inner wall of the reactor body 100, away from the mixture composed of raw materials and catalyst. Then, the first adjusting component drives the L-shaped stirring plates 305 on both sides to rotate synchronously in opposite directions in the vertical direction, so that the L-shaped stirring plates 305 on both sides are aligned. The L-shaped stirring plates 305 and the horizontal plane of the mixture are aligned and overlapped on the same plane. Since the first adjusting component is located at the bottom of the stirring rod 104, the low-speed rotation of the stirring rod 104 drives the L-shaped stirring plates 305 on both sides to rotate synchronously at low speed, thus stirring the mixture. At this time, the L-shaped stirring plates 305 on both sides form a strong shear zone near the inner wall of the reactor body 100 through low-speed stirring, promoting uniform mixing of the high-viscosity mixture. Because the viscosity of the high-viscosity fluid is sufficient to suppress the "spinning" phenomenon caused by centrifugal force, there is no need for the baffle plate 40. 5. Disrupting tangential flow, high-viscosity silicone oil is eventually formed through uniform stirring of the mixture. To generate low-viscosity silicone oil, the relevant raw materials and catalyst are first added to the reactor body 100. Then, multiple baffles 405 are driven to descend vertically synchronously via the second adjusting component, causing them to move vertically downwards along the inner wall of the reactor body 100 into the mixture. Then, the L-shaped stirring plates 305 on both sides are driven to rotate synchronously away from the predetermined angle in the vertical direction via the first adjusting component. At this point, the L-shaped stirring plates 305 are no longer perpendicular to the horizontal plane of the mixture. Then, stirring... When the stirring rod 104 rotates at high speed, it drives the L-shaped stirring plates 305 on both sides to rotate synchronously at high speed through the first adjusting component, which stirs the mixture. Since the blades of the L-shaped stirring plates 305 on both sides are tilted at this time, the mixture is pushed axially, forming a circulating flow that is drawn in from below the blades and discharged from above, realizing rapid mixing of the upper and lower layers. In addition, since the low viscosity mixture is prone to forming tangential flow when stirred at high speed, it causes "swirling" in the center of the liquid surface, making it impossible for the mixture to be fully mixed. Therefore, the baffle plate 405 breaks the tangential flow at this time. With the uniform stirring of the mixture, low viscosity silicone oil is finally formed. To generate high-viscosity silicone oil, the second regulating component drives multiple baffles 405 to rise vertically and move away from the mixture. Then, the first regulating component drives the L-shaped stirring plates 305 on both sides to align with and be perpendicular to the horizontal plane of the mixture. Next, the stirring rod 104 drives the L-shaped stirring plates 305 on both sides to rotate synchronously at low speed to stir the high-viscosity mixture. To generate low-viscosity silicone oil, the second regulating component drives multiple baffles 405 to descend vertically into the mixture. Then, the first regulating component drives the L-shaped stirring plates 305 on both sides to rotate away from the preset angle. Next, the stirring rod 104 drives the L-shaped stirring plates 305 on both sides to rotate synchronously at high speed. Since the blades of the L-shaped stirring plates 305 on both sides are tilted at this time, the mixture is pushed axially to form a circulating flow that is drawn in from below the blades and discharged from above, achieving rapid mixing of the upper and lower layers. In addition, the baffles 405 disrupt the tangential flow to ensure uniform stirring of the low-viscosity mixture. Finally, by adjusting the internal structure of the reactor body 100, silicone oil of different viscosities can be generated and stirred.

[0023] like Figure 4 , Figure 7 and Figure 8 As shown, optionally, the first adjustment component includes a square box 300, a second servo motor 301, a first bevel gear 302, a second bevel gear 303, and a rotating rod 304. The second servo motor 301 is fixedly installed on the upper end of the square box 300, and its output axis extends downward into the interior of the square box 300 and is fixedly installed with the first bevel gear 302. The two second bevel gears 303 are symmetrically arranged on both sides inside the square box 300. The first bevel gear 302 is meshed with the second bevel gears 303 on both sides. The rotating rod 304 is fixed in the middle of the second bevel gear 303. The outer side of the rotating rod 304 is rotatably connected to the middle of the side wall of the square box 300 through a bearing. The end of the rotating rod 304 away from the second bevel gear 303 is fixed to the end of the L-shaped stirring plate 305.

[0024] In this embodiment, the second servo motor 301 starts and drives the first bevel gear 302 to rotate. Since the first bevel gear 302 is meshed with the second bevel gears 303 on both sides, the rotation of the first bevel gear 302 drives the second bevel gears 303 on both sides to rotate synchronously in opposite directions. Then, through the connected rotating rod 304, the L-shaped stirring plates 305 on both sides rotate synchronously towards each other or synchronously away from each other in the vertical direction. When the L-shaped stirring plates 305 on both sides rotate synchronously in opposite directions and align to overlap on the same plane, the L-shaped stirring plates 305 are perpendicular to the horizontal plane of the mixture. The L-shaped stirring plates 305 on both sides form a strong shear zone near the inner wall of the reactor body 100 through low-speed stirring, which promotes the uniform mixing of the high-viscosity mixture. When the L-shaped stirring plates 305 on both sides rotate synchronously away from the preset angle in the vertical direction, the L-shaped stirring plates 305 on both sides rotate at high speed to stir the low-viscosity mixture. Since the blades of the L-shaped stirring plates 305 on both sides are inclined, the mixture is pushed axially to form a circulating flow that is drawn in from below the blades and discharged from above, realizing rapid mixing of the upper and lower layers.

[0025] like Figure 2 , Figure 3 and Figure 6 As shown, optionally, the second adjustment component includes a lifting plate 400, a central hole 401, a reciprocating screw 402, a third servo motor 403, a connecting plate 404, and a baffle plate 405. The central hole 401 is located in the middle of the lifting plate 400. The outer side of the stirring rod 104 is in contact with the inner side of the central hole 401. The reciprocating screw 402 is threadedly connected to the inside of the lifting plate 400. The upper end of the reciprocating screw 402 is fixed on the output shaft of the third servo motor 403. The third servo motor 403 is fixed on the inner top surface of the reactor body 100. Multiple evenly distributed connecting plates 404 are fixed on the outer periphery of the lifting plate 400. The end of the connecting plate 404 facing away from the lifting plate 400 is fixedly connected to the upper end of the corresponding baffle plate 405.

[0026] In this embodiment, the third servo motor 403 starts and drives the reciprocating screw 402 to rotate. Since the reciprocating screw 402 is threadedly connected to the lifting plate 400, and the lifting plate 400 is limited by the stirring rod 104, the rotation of the reciprocating screw 402 can drive the lifting plate 400 to rise and fall vertically. In turn, the connecting plate 404 connected to it can drive multiple baffles 405 to rise and fall vertically. When the multiple baffles 405 rise vertically to a preset height at the same time, away from the mixture composed of raw materials and catalyst, the viscosity of the high-viscosity fluid is sufficient to suppress the "swirling" phenomenon caused by centrifugal force, so there is no need for the baffles 405 to disrupt the tangential flow. When the multiple baffles 405 fall vertically to the interior of the mixture at the same time, the low-viscosity mixture is prone to forming a tangential flow when stirred at high speed, causing "swirling" in the center of the liquid surface, making it impossible for the mixture to be fully mixed. Therefore, at this time, the baffles 405 disrupt the tangential flow.

[0027] like Figure 2 and Figure 3 As shown, optionally, there is a gap between the L-shaped stirring plate 305 and the inner wall of the reactor body 100, and the baffle plate 405 does not interfere with the L-shaped stirring plate 305 when it is raised and lowered vertically.

[0028] In this embodiment, when stirring high-viscosity silicone oil, there is a gap between the L-shaped stirring plate 305 and the inner wall of the reactor body 100. When the L-shaped stirring plate 305 rotates at low speed, a strong shear zone is formed near the inner wall of the reactor body 100, which promotes the uniform mixing of the high-viscosity mixture and can also scrape off the high-viscosity silicone oil adhering to the inner wall of the reactor body 100. When stirring low-viscosity silicone oil, the baffle plate 405 is located inside the mixture and attached to the inner wall of the reactor body 100. When the L-shaped stirring plate 305 rotates at high speed, the baffle plate 405 breaks the tangential flow, so that the mixture is fully mixed.

[0029] like Figure 3 and Figure 6 As shown, optionally, a rubber protective sheet 406 is attached to the outer side of the baffle 405, and the rubber protective sheet 406 slides in contact with the inner wall of the reactor body 100.

[0030] In this embodiment, by attaching a rubber protective sheet 406 to the outside of the baffle plate 405, the rubber protective sheet 406 is ensured to slide against the inner wall of the reactor body 100 when the baffle plate 405 is raised and lowered vertically, thus preventing the baffle plate 405 from scratching the inner wall of the reactor body 100.

[0031] like Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, optionally, a protective cover 200 is provided on the outside of the second servo motor 301. Multiple evenly distributed extension plates 201 are fixedly fixed to the lower outer side of the protective cover 200. The extension plates 201 are fastened to the upper end of the square box 300 by locking bolts 202. The upper end of the protective cover 200 is fixed to the bottom end of the stirring rod 104.

[0032] In this embodiment, the locking bolt 202 facilitates the disassembly and assembly of the stirring rod 104 and the first adjustment component for maintenance, and the protective cover 200 can also protect the second servo motor 301.

[0033] like Figure 1 and Figure 2 As shown, optionally, a drive assembly is provided at the upper end of the reactor body 100, which can drive the stirring rod 104 to rotate.

[0034] In this embodiment, the stirring rod 104 is driven by the driving component to rotate inside the reaction vessel body 100, so as to stir the mixture.

[0035] like Figure 1 and Figure 2 As shown, optionally, the drive assembly includes a frame 101, a reducer 102, and a first servo motor 103. The frame 101 is fixed to the upper end of the reactor body 100, the reducer 102 is fixed to the upper end of the frame 101, the first servo motor 103 is fixed to the upper end of the reducer 102, and the output end of the first servo motor 103 is fixedly connected to the input end of the reducer 102. The output end of the reducer 102 is fixedly connected to the upper end of the stirring rod 104.

[0036] In this embodiment, the output speed of the first servo motor 103 is reduced by the reducer 102, thereby controlling the stirring rod 104 to rotate. The first servo motor 103 can control the speed of the stirring rod 104. Since it is existing technology, its specific structure, connection relationship and working principle will not be described here.

[0037] like Figure 3 and Figure 6 As shown, optionally, a limiting base plate 407 is fixed at the bottom end of the reciprocating screw 402, and the connecting plate 404 does not interfere with the L-shaped stirring plate 305 when it is raised or lowered.

[0038] In this embodiment, a limiting base plate 407 is set to prevent the lifting plate 400 from moving and falling off on the reciprocating screw 402, thus playing a limiting role. When the connecting plate 404 is raised and lowered, it does not interfere with the L-shaped stirring plate 305, ensuring the rationality of the structure.

[0039] like Figure 1-8 As shown, a method for preparing a low thermal conductivity silicone oil, based on the production equipment for a low thermal conductivity silicone oil as described above, includes the following steps: S1: If it is necessary to generate high viscosity silicone oil, firstly, the relevant raw materials and catalysts are put into the reactor body 100. The second adjustment component drives multiple baffles 405 to rise vertically and move away from the mixture. Then, the first adjustment component drives the L-shaped stirring plates 305 on both sides to align and be perpendicular to the horizontal plane of the mixture. Then, the stirring rod 104 drives the L-shaped stirring plates 305 on both sides to rotate synchronously at low speed to stir the high viscosity mixture and generate high viscosity silicone oil. S2: If low-viscosity silicone oil is required, the relevant raw materials and catalysts are first put into the reactor body 100. The second adjustment component drives multiple baffles 405 to descend vertically into the mixture simultaneously. Then, the first adjustment component drives the L-shaped stirring plates 305 on both sides to rotate at a preset angle. Next, the stirring rod 104 drives the L-shaped stirring plates 305 on both sides to rotate at high speed simultaneously, stirring to generate low-viscosity silicone oil. Finally, the generation and stirring of silicone oil of different viscosities can be achieved by adjusting the structural state inside the reactor body 100.

[0040] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
