Description

Technical Field

[0001] This utility model relates to the field of coating reaction synthesis chamber technology, specifically a coating reaction synthesis chamber that is nuclear-grade and resistant to extreme radiation environments. Background Technology

[0002] A coating reaction synthesis chamber is a closed reaction vessel used to complete key chemical synthesis reactions (such as polymerization, condensation, and esterification) in coatings (especially resin-based coatings). Its core features include a precise temperature control, pressurization / vacuum, stirring, and inert gas protection system to provide a stable and controllable reaction environment for the raw materials, ensuring that the chemical reaction proceeds efficiently and uniformly. This results in the synthesis of coating base materials with specific molecular structures and properties, making it a core piece of equipment for achieving customized product performance in coating production.

[0003] After the reaction is complete, the materials are prone to stratification due to density differences. However, the stirring mechanism of the existing synthesis chamber is mostly designed with a fixed height, which can only stir the materials at a single depth in the tank laterally. It cannot cover different stratified areas, resulting in poor stirring efficiency, low uniformity of subsequent mixing, and affecting the consistency of coating product performance.

[0004] Based on this, a nuclear-grade coating reaction synthesis chamber resistant to extreme radiation environments is now available, which can eliminate the drawbacks of existing devices. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-5As shown, the nuclear-grade coating reaction synthesis chamber for extreme radiation environments includes a base 1, with two mounting brackets 2 on the top of the base 1. A reaction vessel 3 is rotatably mounted between the two mounting brackets 2 via bearings, and a drive mechanism 4 is installed inside one of the mounting brackets 2.

[0028] A sampling mechanism 5 is provided on one side of the reaction vessel 3, a hydraulic cylinder 6 is provided on the top side of the base 1, a lifting plate 7 is provided at the top of the hydraulic cylinder 6, a sealing mechanism 8 is provided at the bottom of the lifting plate 7, and a stirring mechanism 9 is provided at the top of the lifting plate 7.

[0029] In this embodiment, a double sealing structure is formed by the elastic cooperation of the lifting cover 81 and the sealing cover 84, which greatly improves the sealing performance and can accurately control the gas pressure inside the tank to adapt to the pressure requirements of different coating synthesis. At the same time, it avoids gas leakage and the mixing of external impurities, ensuring the cleanliness of nuclear-grade coatings. The temperature sensor and electric heating layer 34 of the reaction tank 3 can stably maintain the reaction temperature of the materials. The multiple sets of stirring blades 93 of the stirring mechanism 9 realize transverse stirring. The scraper 95 and the filter plate 94 work together to prevent filter blockage and perform preliminary impurity removal. After the reaction, the hydraulic cylinder 6 drives the stirring mechanism 9 and the sealing mechanism 8 to rise and fall synchronously. Through longitudinal shearing and transverse stirring, the problem of material stratification is quickly solved, ensuring the uniformity and purity of the product and meeting the performance requirements of nuclear-grade coatings.

[0030] In one embodiment, such as Figure 2 and Figure 3As shown, the sealing mechanism 8 includes a lifting cover 81, which is fixedly installed at the bottom of the lifting plate 7. Two mounting cylinders 82 are provided on the top of the lifting cover 81. Sliding rods 83 are slidably installed inside each of the two mounting cylinders 82. The bottom ends of the two sliding rods 83 penetrate the lifting cover 81 and are connected to a sealing cover 84. A top cover 85 is fixedly installed on the top of each of the two mounting cylinders 82. A spring 86 is provided inside the two mounting cylinders 82 and between the top cover 85 and the sliding rod 83. The stirring mechanism 9 includes a second motor 91, which is fixedly installed on the top of the lifting plate 7. The output end of the second motor 91 penetrates the lifting plate 7 and is connected to a rotating shaft 92. Multiple stirring blades 93 are keyed to the outside of the rotating shaft 92. A filter plate 94 is provided outside the rotating shaft 92 and between two of the stirring blades 93. A scraper is provided outside the rotating shaft 92 and above the filter plate 94. The bottom of the scraper 95 contacts the top of the filter plate 94. The second motor 91 of the stirring mechanism 9 is activated, which drives the rotating shaft 92 to rotate. Multiple stirring blades 93 outside the rotating shaft 92 stir the material laterally. At the same time, the rotating shaft 92 drives the scraper 95 to rotate synchronously. The scraper 95 continuously cleans the surface of the filter plate 94 to prevent impurities from accumulating and clogging the filter plate 94. The filter plate 94 performs preliminary filtration of the material to remove impurities and ensure product purity. After the reaction is completed, the material is prone to stratification. At this time, the hydraulic cylinder 6 drives the lifting plate 7 to move the stirring mechanism 9 and the sealing mechanism 8 up and down synchronously. The stirring blades 93 move with the lifting plate 7 in the longitudinal direction to perform a combination of longitudinal shearing and transverse stirring mixing operation on the stratified materials of different depths in the reaction tank 3, so as to quickly achieve uniform mixing of the materials. The sealing mechanism 8 always maintains a sealed state with the opening of the reaction tank 3 during the lifting process to prevent the material from splashing or coming into contact with the external environment.

[0031] In one embodiment, such as Figure 1 and Figure 4 As shown, the drive mechanism 4 includes a worm gear 41, which is rotatably mounted inside the mounting frame 2 via bearings. A worm wheel 42 is meshed with the outside of the worm gear 41, and the worm wheel 42 is rotatably mounted to the mounting frame 2. A first motor 43 is fixedly mounted on one side of the mounting frame 2, and the worm gear 41 is driven by the first motor 43. An inspection door 44 is rotatably mounted on the other side of the mounting frame 2 via a hinge. When the first motor 43 of the drive mechanism 4 is started, the first motor 43 drives the worm gear 41 to rotate, which in turn drives the worm wheel 42 to rotate, thereby causing the reaction tank 3 to rotate around the axis between the mounting frames 2 to adjust the angle. This facilitates cleaning of the inside of the reaction tank 3 and allows residual materials or impurities to be completely discharged by tilting.

[0032] In one embodiment, such as Figure 1 and Figure 4As shown, the sampling mechanism 5 includes a sampling tube 51, which is fixedly connected to one side of the reaction vessel 3. A sampling valve 52 is provided at the top of the sampling tube 51, and a sampling bottle 53 is threadedly connected to the bottom of the sampling tube 51. An inlet pipe 11 and an outlet pipe 10 are respectively provided on one side of the reaction vessel 3, above and below the sampling tube 51. A valve body is provided at the top of both the inlet pipe 11 and the outlet pipe 10. If it is necessary to determine the reaction progress, the sampling valve 52 is opened, and the material flows into the sampling bottle 53 through the sampling tube 51. After sampling, the sampling valve 52 is closed, which facilitates the detection of the sample in the sampling bottle 53 and the determination of the reaction progress.

[0033] In one embodiment, such as Figure 1 and Figure 5 As shown, the reaction vessel 3 includes a base layer 31, a radiation-resistant coating 32 on one side of the base layer 31, a corrosion-resistant coating 33 on one side of the radiation-resistant coating 32, a heating layer 34 inside the base layer 31, a heat insulation layer 35 on the other side of the base layer 31, and a protective layer 36 on one side of the heat insulation layer 35. The corrosion-resistant coating 33 is made of polytetrafluoroethylene, the radiation-resistant coating 32 is made of epoxy-ceramic composite coating, the heat insulation layer 35 is made of rock wool, the protective layer 36 is made of stainless steel, and the base layer 31 is made of low-alloy steel. The reaction vessel 3 adopts a multi-layer structure design, which can adapt to extreme radiation environments and resist material corrosion. The heat insulation layer 35 reduces heat loss to reduce energy consumption, and the whole is adapted to the special environment of nuclear-grade coating synthesis.

[0034] The above embodiments disclose a nuclear-grade coating reaction synthesis chamber resistant to extreme radiation environments. The coating raw materials to be reacted are added to the reaction vessel 3 through the feed pipe 11. A temperature sensor inside the reaction vessel 3 monitors the material temperature in real time. The heating layer 34 (electric heating) inside the base layer 31 is activated to maintain the material at a suitable reaction temperature. The lifting cover 81 moves downward with the lifting plate 7, and the sliding rod 83 drives the sealing cover 84 to contact the opening of the reaction vessel 3. As the lifting plate 7 continues to press down, the sliding rod 83 slides upward along the mounting cylinder 82 and compresses the spring 86. The reaction force of the spring 86 causes the sealing cover 84 to tightly fit the opening of the reaction vessel 3, forming a double sealing structure with the lifting cover 81, significantly improving the sealing performance. If the reaction requires a pressurized or negative pressure environment, an external pressurization device is activated through the conduit connected to the top of the lifting cover 81 to introduce inert gas (such as nitrogen) into the reaction vessel 3 or extract gas from the vessel, precisely controlling the gas pressure inside the vessel to meet the gas pressure requirements of different coating synthesis processes.

[0035] The second motor 91 of the stirring mechanism 9 is started, which drives the rotating shaft 92 to rotate. Multiple stirring blades 93 outside the rotating shaft 92 stir the material laterally. At the same time, the rotating shaft 92 drives the scraper 95 to rotate synchronously. The scraper 95 continuously cleans the surface of the filter plate 94 to prevent impurities from accumulating and clogging the filter plate 94. The filter plate 94 performs preliminary filtration of the material to remove impurities and ensure product purity.

[0036] After the reaction is complete, the material is prone to stratification. At this time, the hydraulic cylinder 6 drives the lifting plate 7 to move the stirring mechanism 9 and the sealing mechanism 8 up and down synchronously. The stirring blade 93 moves with the lifting plate 7 in the longitudinal direction, and performs a combination of longitudinal shearing and transverse stirring on the stratified material at different depths in the reaction tank 3 to quickly achieve uniform mixing of the material. The sealing mechanism 8 always maintains a sealed state with the opening of the reaction tank 3 during the lifting process to prevent material from splashing or coming into contact with the external environment. After the mixing is completed, the qualified material is discharged through the discharge pipe 10. The hydraulic cylinder 6 drives the lifting plate 7 to move upward, so that the stirring mechanism 9 and the sealing mechanism 8 are separated from the reaction tank 3. At this time, a large amount of impurities will remain on the surface of the filter plate 94. The first motor 43 of the drive mechanism 4 is started. The first motor 43 drives the worm gear 41 to rotate. The worm gear 41 drives the worm wheel 42 to rotate, which in turn makes the reaction tank 3 rotate around the axis between the mounting brackets 2 to adjust the angle. This facilitates cleaning of the inside of the reaction tank 3 and can also completely discharge the residual material or impurities by tilting.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
