Abstract

Technical Field
[0001] This utility model relates to the field of perfluoropolyether reaction production technology, and in particular to a catalytic device for the perfluoropolyether reaction process. Background Technology
[0002] Perfluoropolyethers, as fluoropolymers with excellent properties, play a crucial role in many high-end fields. Their preparation methods mainly include photocatalytic polymerization and anionic catalytic polymerization.
[0003] However, current preparation processes and catalytic devices have many problems. Although anionic catalytic polymerization produces products with excellent high-temperature resistance, the raw materials are expensive, the production cost is high, and the introduction of fluoride ions as catalysts leads to wastewater discharge and environmental pressure. Photocatalytic polymerization, on the other hand, has low raw material costs and is conducive to large-scale production, but its existing reaction devices have defects such as material blocking the light source, easy damage to the light source, and low photocatalytic efficiency.
[0004] To address the shortcomings of the aforementioned technologies, we propose a catalytic device for the perfluoropolyether reaction process. Utility Model Content

The reaction catalytic component includes a structural disk base, a cone, an inner cylinder, and an LED lamp assembly.

A plurality of through holes are evenly distributed on the side wall of the cone.
[0008] Furthermore, the inner cylinder is fixedly installed on the upper side of the base plate, and the inner cylinder is made of high-strength transparent quartz glass.
[0009] Furthermore, the LED light groups are evenly and fixedly installed on the inner wall of the perfluoropolyether reaction cylinder.

[0011] Furthermore, a top cover is fixedly installed on the upper side of the top ring plate, a feeding cylinder is fixedly installed on the top cover, and a sealing cap is fastened to the upper side of the feeding cylinder.

[0016] In this invention, a catalytic device for the perfluoropolyether reaction process is described. The catalytic reaction assembly includes key components such as a stirring paddle, a cone, an inner cylinder, and an LED light group. During the perfluoropolyether reaction, the reactants are first added to the cone. The stirring paddle rotates inside the cone to thoroughly mix the materials. The cone then rotates at high speed to further mix the materials. Under centrifugal force, the mixed solution precipitates from through holes on the upper side wall of the cone.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] Reference Figures 1-6 A catalytic device for a perfluoropolyether reaction process includes a perfluoropolyether reaction cylinder 1, a base plate 2 fixedly installed at the bottom of the perfluoropolyether reaction cylinder 1, and a reaction catalytic component 7 disposed inside the perfluoropolyether reaction cylinder 1. The reaction catalytic component 7 includes a structural disk base 71, a cone 72, an inner cylinder 73, and an LED lamp group 74. A second drive motor 76 is fixedly installed on the upper side of the structural disk base 71. The output end of the second drive motor 76 rotates through to the lower side of the structural disk base 71, and a rotating column 77 is fixedly installed below the output end of the second drive motor 76. Several stirring blades 78 are fixedly installed on the side wall of the rotating column 77. A supporting rotating shaft 710 is rotatably installed on the upper side of the base plate 2. The upper end of the supporting rotating shaft 710 is fixedly connected to the bottom of the cone 72. Several through holes 79 are evenly distributed on the side wall of the cone 72.
[0026] With the above-described configuration, the through hole 79 is located on the upper side wall of the cone 72. When the material is added into the cone 72 in the early stage, the mixture is located below the area of the through hole 79, so that the mixture will not precipitate out from the through hole 79 during centrifugation.
[0027] In this method, the inner cylinder 73 is fixedly installed on the upper side of the base plate 2, and the inner cylinder 73 is made of high-strength transparent quartz glass.
[0028] Through the above-mentioned design, high-strength transparent quartz glass material exhibits good chemical stability and high structural strength.
[0029] In this method, the LED light groups 74 are evenly distributed and fixedly installed on the inner wall of the perfluoropolyether reaction cylinder 1.
[0030] With the above-mentioned setup, when the LED light group 74 is turned on, it can uniformly irradiate ultraviolet light through the inner cylinder 73 to the inside, which can perform a photocatalytic reaction on the material that precipitates through the through hole 79.
[0031] In this method, a top ring plate 8 is fixedly installed on the upper end of the perfluoropolyether reaction cylinder 1 and the inner cylinder 73. A sealing ring 81 is fixedly installed on the inner side of the top ring plate 8. A number of balls 82 are equidistantly embedded on the inner wall of the top ring plate 8. The balls 82 roll in contact with the outer wall of the upper port of the cone cylinder 72.
[0032] The sealing ring 81, as described above, provides a sealing protection for the working area of the ball bearing 82. In addition, the rolling contact between the ball bearing 82 and the outer wall of the upper port of the cone 72 reduces frictional loss when the cone 72 rotates at high speed.
[0033] In this method, a top cover 9 is fixedly installed on the upper side of the top ring plate 8, a feeding cylinder 10 is fixedly installed on the top cover 9, a sealing cover 11 is fastened to the upper side of the feeding cylinder 10, a number of connecting parts 75 are fixedly connected between the structural plate base 71 and the outer wall of the perfluoropolyether reaction cylinder 1, and the rotating column 77 rotates through the top cover 9.
[0034] With the above configuration, when the second drive motor 76 is turned on, it can drive the rotating column 77 and the stirring blades 78 on the outer wall of the rotating column 77 to stir inside the cone 72, thereby accelerating the mixing of materials.
[0035] In this method, a first drive motor 5 is fixedly installed at the bottom of the base plate 2. The output end of the first drive motor 5 is connected to the support shaft 710 via a coupling. A discharge pipe 3 is fixedly installed at the bottom of the base plate 2. A solenoid valve 4 is fixedly installed on the discharge pipe 3. A controller 6 is fixedly installed on the outer wall of the perfluoropolyether reaction cylinder 1.
[0036] With the above configuration, when the first drive motor 5 starts, it can drive the cone 72 to rotate at high speed through the support shaft 710, so as to centrifuge the material inside the cone 72.
[0037] The working principle of the catalytic device for the perfluoropolyether reaction process provided by this utility model is as follows:
[0038] Raw material addition: First, open the sealing cap 11 on the upper side of the feeding cylinder 10, and add the raw materials required for the perfluoropolyether reaction into the cone 72 through the feeding cylinder 10. Since the through hole 79 is located on the upper side wall of the cone 72, the mixture added in the early stage is located below the area of the through hole 79. Therefore, the mixture will not precipitate out from the through hole 79 before the centrifugal action occurs in the subsequent operation. After the addition is completed, re-fasten the sealing cap 11 onto the feeding cylinder 10 to prevent material leakage and the entry of external impurities.
[0039] Preliminary mixing: The second drive motor 76 on the upper side of the structure plate 71 is started. The output end of the second drive motor 76 drives the rotating column 77 to rotate. The stirring blades 78 on the side wall of the rotating column 77 rotate inside the cone 72. The stirring blades 78 fully stir the material in the cone 72, so that the raw materials are initially mixed evenly in the cone 72, laying the foundation for subsequent reactions.
[0040] Further mixing and solution precipitation: The first drive motor 5 at the bottom of the base plate 2 is turned on. The output end of the first drive motor 5 drives the support shaft 710 to rotate through the coupling, thereby causing the cone 72 to rotate at high speed. The high-speed rotation of the cone 72 generates centrifugal force. Under the action of centrifugal force, the solution initially mixed in the cone 72 gradually precipitates out from the through hole 79 on the upper side wall of the cone 72.
[0041] Photocatalytic reaction: When the LED light group 74, which is uniformly and fixedly installed on the inner wall of the perfluoropolyether reaction cylinder 1, is turned on, it emits ultraviolet light. Since the inner cylinder 73 is made of high-strength transparent quartz glass, it has good chemical stability and high structural strength. The ultraviolet light can pass through the inner cylinder 73 and evenly irradiate the solution precipitated from the through hole 79. Under the irradiation of ultraviolet light, the solution undergoes a photocatalytic reaction, which accelerates the reaction and generation of perfluoropolyether.
[0042] Product discharge: After the perfluoropolyether reaction is completed, the solenoid valve 4 on the discharge pipe 3 is opened. Under the action of gravity, the perfluoropolyether product generated by the reaction is discharged through the discharge pipe 3 for subsequent collection and processing. During the entire reaction process, the controller 6 on the outer wall of the perfluoropolyether reaction cylinder 1 can control and adjust the parameters of the first drive motor 5, the second drive motor 76, and the LED lamp group 74 to ensure that the reaction is carried out under suitable conditions.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
