Description

[0002] In organic chemical synthesis and the preparation of perfluoroalkane, reaction vessels are commonly used core equipment. Traditional reaction vessels are mostly of fixed structure, relying solely on agitators for mixing and reaction. For materials with high viscosity or complex reaction systems, it is difficult to achieve rapid and uniform mixing, affecting reaction efficiency and product quality. Furthermore, some reactions require multi-angle and dynamic adjustment of the reaction environment, which fixed reaction vessels cannot meet, limiting the optimization and expansion of organic synthesis and perfluoroalkane preparation processes.

[0003] In the preparation of perfluoroalkane, reactions such as fluorination and polymerization of fluorine-containing raw materials are often involved.

Traditional reactors are prone to increased side reactions due to insufficient mixing, which reduces the yield and purity of perfluoroalkane. Furthermore, some processes in the preparation of perfluoroalkane require phased adjustments to the reaction posture of materials, which is difficult to adapt to fixed reactors, thus restricting process upgrades.

[0043] like Figure 1-5 As shown, this utility model provides a rotatable perfluoroalkane preparation reactor, comprising: a double-layer reactor, including: a double-layer reaction vessel 110, which provides a suitable reaction space for the preparation of perfluoroalkane; the double-layer reaction vessel 110 has a double-layer structure, the inner layer is used to contain reactants for organic synthesis or perfluoroalkane preparation reactions, and the outer layer can be equipped with a heat-conducting medium channel to achieve precise control of the reaction temperature; the inner vessel body of the double-layer reactor is made of a chemically corrosion-resistant material, such as a polytetrafluoroethylene lining or a special alloy material, suitable for corrosive materials and reaction conditions in perfluoroalkane preparation; a stirring motor 130 is fixedly installed on the top of the double-layer reaction vessel 110; the stirring motor 130 is a variable frequency controlled servo motor, which can adjust according to the characteristics of the reactants and the reaction...

[0044] The base plate 140 is a rectangular flat plate, which serves as the basic support component of the entire equipment and provides a stable installation reference surface; the mounting plate 150 is a rectangular flat plate with a rectangular through groove 152 in the middle; the mounting plate 150 is fixedly installed on the upper surface of the base plate 140 by a plurality of support columns 151; in this embodiment, there are four support columns 151, which are set at the four corners of the mounting plate 150.

[0045] A rotatable support frame 160 is rotatably connected to the upper surface of the mounting plate 150 and fixedly connected to the double-layer reactor, providing support for the double-layer reactor and driving its rotation. The rotatable support frame 160 includes: two first right-angled triangular support frames 161, whose right angles are rotatably mounted on the upper surface of the mounting plate 150 via connecting lugs 165; the two first right-angled triangular support frames 161 are arranged in parallel; multiple crossbeams 164, whose two ends are fixedly connected to the two first right-angled triangular support frames 161 respectively, enhancing the overall structural strength of the rotatable support frame 160; in this embodiment, the number of crossbeams 164 is three; two second right-angled triangular support frames 162, one of whose right-angled sides is horizontally arranged, and the other right-angled side is fixedly connected to the right-angled side of the first right-angled triangular support frame 161; the two... A second right-angled triangular support frame 162 is disposed at the end of the right-angled side of the first right-angled triangular support frame 161; two third right-angled triangular support frames 163, one of which has a horizontal right-angled side and the other right-angled side is fixedly connected to the right-angled side of the first right-angled triangular support frame 161; the two third right-angled triangular support frames 163 are disposed in the middle of the right-angled side of the first right-angled triangular support frame 161; wherein, the second right-angled triangular support frame 162 and the third right-angled triangular support frame 163 have the same shape and size; the double-layer reaction vessel 110 is fixedly connected to the second right-angled triangular support frame 162 and the third right-angled triangular support frame 163, thereby fixing the double-layer reaction vessel 110 on the rotatable support frame 160; the right-angled side end of the first right-angled triangular support frame 161 is also provided with a shock-absorbing support foot 166.

[0046] A slider 170 is slidably disposed within the rectangular through groove 152, serving as a connection medium between the hydraulic cylinder 180 and the hydraulic rod 190, transmitting driving force. The hydraulic cylinder 180 is axially disposed along the rectangular through groove 152. The cylinder end 181 of the hydraulic cylinder 180 is fixedly mounted on the lower surface of the mounting plate 150, and the free end 182 is fixedly connected to the slider 170. The hydraulic cylinder 180 can precisely control the extension and retraction speed and stroke, ensuring smooth and uninterrupted rotation of the double-layer reactor. The hydraulic rod 190 has its cylinder end 191 hinged to the slider 170 for rotational connection, and its free end 192 hinged to the rotatable support frame 160 for rotational connection. The hydraulic rod 190 converts the linear extension and retraction motion of the hydraulic cylinder 180 into the rotational motion of the rotatable support frame 160, thereby adjusting the reactor angle.

[0047] like Figure 6 As shown, in this embodiment, there are two stirring paddles, which are arranged along the axial direction of the stirring shaft 121; the stirring paddle is composed of multiple stirring blades 122 evenly distributed around the circumference of the stirring shaft 121; when the stirring paddle rotates, it can fully disturb the material and enhance the mixing effect.

[0048] In the preparation of perfluoroalkane, the reactants are added to the inner layer of the double-layer reactor through the feed inlet 123, and the gaseous materials are added to the inner layer of the double-layer reactor through the gas inlet 124. Heating or cooling media are introduced through the outer heat-conducting medium channel according to the reaction requirements to control the reaction temperature. The stirring motor 130 is started, which drives the stirring shaft 121 to rotate, thereby causing the stirring paddle to rotate and mix the materials. According to the reaction progress, the speed of the stirring motor 130 can be adjusted by frequency conversion control to change the stirring intensity. For example, a lower speed can be used when the material viscosity is low in the early stage of the reaction, and the speed can be increased when the material viscosity rises in the middle stage of the reaction to ensure the mixing effect. When the reaction environment needs to be adjusted, such as to allow the materials to react or mix in an inclined state, the hydraulic cylinder 180 is activated. The piston rod of the hydraulic cylinder 180 extends and retracts, driving the hydraulic rod 190 to extend and retract, pushing the rotatable support frame 160 to rotate. This causes the double-layer reactor to rotate and tilt along with the rotatable support frame 160. By utilizing the combined force of the material's own gravity and the disturbance of the stirring paddle, convective mixing is enhanced, solving the problem of uneven local polymerization under high viscosity and improving the uniformity of the molecular weight distribution of perfluoroalkane polymers. After adjusting the tilt angle of the double-layer reactor to the target angle, the hydraulic cylinder 180 is kept in the extended and retracted state, maintaining the tilted posture of the double-layer reactor until the reaction is completed. After the reaction is completed, stirring and temperature control are stopped, and the perfluoroalkane products are discharged through the discharge port 125, completing the perfluoroalkane preparation process.

[0049] During rotation, the rotatable support frame 160 cooperates with the base to ensure stable rotation of the double-layer reactor, achieving angle adjustment from 0 to 90 degrees. After adjustment to the target angle, the hydraulic cylinder 180 is kept in the extended / retracted state, allowing the double-layer reactor to maintain the reaction at that angle, meeting the requirements of special reaction processes for material posture and mixing methods.

[0050] In the preparation of perfluoroalkanes, if a fluorinated monomer polymerization reaction is carried out, initially, liquid fluorinated monomers and initiators are added to the inner layer of the reactor through the feed inlet 123. The reactor is heated to the polymerization temperature using the heat conduction channel in the inner layer. The stirring motor 130 is then started, driving the stirring shaft 121 to rotate, thereby causing the stirring paddle to rotate at a low speed and stir the materials initially. As the reaction proceeds, the viscosity of the system increases. The hydraulic cylinder 180 is used in conjunction to rotate the double-layer reactor to a tilt angle of 30-60 degrees, while simultaneously increasing the speed of the stirring motor 130. The combined force of the material's own gravity and the stirring paddle enhances the convective mixing of the material, reducing the problem of uneven polymerization caused by high viscosity and improving the uniformity of the molecular weight distribution of the perfluoroalkane polymer.

[0051] If the preparation of perfluoroalkane involves a fluorination reaction, the gaseous fluorinating agent and the liquid material need to be in full contact in stages during the reaction. The liquid material is added through the feed port 123, and the gaseous fluorinating agent is added through the gas inlet 124. The hydraulic cylinder 180 drives the double-layer reactor to rotate to a 90-degree vertical position, so that the liquid material forms a thin liquid layer on the reactor wall, increasing the contact area with the gaseous fluorinating agent, promoting the full progress of the fluorination reaction, improving the conversion rate and purity of perfluoroalkane, and adapting to the diversified and refined process requirements in the preparation of perfluoroalkane.

[0052] The rotatable perfluoroalkane preparation reactor provided by this utility model, through the setting of a rotatable double-layer reactor and the coordination of a stirring motor, enables multi-angle and dynamic mixing and reaction of materials in the preparation of perfluoroalkanes, improving the uniformity of material mixing, promoting the full reaction, and helping to improve reaction efficiency and product quality. The double-layer structure design combined with the heat-conducting medium channel can precisely control the reaction temperature, meeting the needs of temperature-sensitive reactions in the preparation of perfluoroalkanes. The inner reactor body made of chemically corrosion-resistant material ensures long-term stable use of the equipment in corrosive environments. The cooperation between the hydraulic cylinder and the rotatable support frame makes the rotation of the double-layer reactor stable and controllable. The rotation adjustment of 0-90 degrees can adapt to various reaction process requirements, providing an equipment foundation for the process optimization of perfluoroalkane preparation and expanding the application scenarios of the reactor.

They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
