Description

Technical Field

[0001] This application relates to the field of chemical equipment technology, and in particular to a reaction vessel for producing ultra-high solids, low-viscosity waterborne epoxy modified resin coatings. Background Technology

[0002] As a container with physical or chemical reaction functions, a reaction vessel can achieve functions such as heating, evaporation, cooling, and high- and low-speed mixing through reasonable structural design and parameter configuration. It is widely used in many fields such as petroleum, chemical, rubber, pesticide, dye, pharmaceutical and food. It is a key pressure vessel for completing processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization and condensation. Common types include reactors, reaction vessels, decomposition vessels and polymerization vessels. Their materials usually include carbon manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloys and other composite materials.

[0003] An existing patent (publication number: CN216419396U) discloses a reaction vessel for producing high weather-resistant waterborne epoxy modified resin coatings. To solve the problem that the existing reaction vessels for waterborne epoxy modified resin coatings have a slow feeding speed due to the viscous physical properties of the material itself, and the material easily sticks to the inner wall of the reaction vessel, requiring manual scraping and wasting a lot of manpower.

[0004] While the aforementioned comparative cases can scrape off residual material from the inner wall of the reactor, thus solving to some extent the problems of slow material feeding and material adhesion to the inner wall requiring manual cleaning, the device still has some shortcomings: the material scraper and connecting rod are welded together, resulting in hard contact between the scraper and the inner wall of the reactor during material scraping, which can easily cause wear on the inner wall with long-term use and affect the service life of the reactor; furthermore, the device does not involve temperature control-related structures, making it impossible to accurately control the temperature inside the reactor, and the production of high weather-resistant waterborne epoxy modified resin coatings is quite sensitive to temperature, with unstable temperature affecting the performance and quality of the coating; therefore, a reactor for producing high weather-resistant waterborne epoxy modified resin coatings is provided. Utility Model Content

[0005] The purpose of this application is to provide a reactor for producing ultra-high solids, low-viscosity waterborne epoxy modified resin coatings. It avoids the hard contact between the traditional welded scraper and the inner wall, can efficiently scrape off residual materials, extend the service life of the reactor body, and solves the problem of unstable temperature in traditional devices, ensuring that the coating reacts at a suitable temperature.

The output end of the forward / reverse motor passes through the top cover and is fixedly connected to a rotating rod. The rotating rod is rotatably connected inside the reaction vessel body. Rotating plates are fixedly connected to both the upper and lower surfaces of the rotating rod. Buffer mechanisms are provided at both ends of the two sets of rotating plates, and cleaning plates are provided at the ends furthest from the buffer mechanisms.

The movable shell is movably connected to the side of the fixed shell and fixedly connected to the cleaning plate at the end away from the fixed shell. A fixed block is fixedly connected inside the fixed shell.

The other end of the spring and the telescopic rod is fixedly connected inside the movable shell. A stirring blade is provided on the surface of the rotating rod. By adopting the above technical solution, the rotating rod and stirring blade are driven by a forward and reverse motor to achieve full stirring of materials. The buffer mechanism at both ends of the rotating plate, together with the cleaning plate, uses the elasticity of the spring and the telescopic rod to keep the cleaning plate in contact with the inner wall of the reactor body. This can effectively scrape off residual materials, avoid wear on the inner wall caused by hard contact, extend the service life of the equipment, and eliminate the need for manual cleaning, thereby improving production efficiency.

[0007] Preferably, the rotating plate has an internal mounting hole, an infrared sensor is fixedly connected inside the mounting hole, a transparent wear-resistant plate is fixedly connected to the side of the mounting hole, the reaction vessel body has an internal mounting groove, an annular heating plate is installed inside the mounting groove, the annular heating plate and the infrared sensor are both electrically connected to a preset threshold controller outside the reaction vessel body, the external controller receives the detection signal from the infrared sensor and controls the start and stop of the annular heating plate and the heating power.

[0010] By adopting the above technical solution, the ball bearings on the side of the pressure plate roll in conjunction with the sliding groove inside the movable shell, reducing the frictional resistance between the fixed shell and the movable shell when the buffer mechanism is working, making the extension and retraction of the cleaning plate smoother, and improving the stability and service life of the buffer mechanism.

[0011] Preferably, the inner walls of both the fixed shell and the movable shell of the buffer mechanism are made of stainless steel, and the fixed block and the pressure plate are made of metal and coated with an anti-corrosion coating.

[0012] By adopting the above technical solution, the inner walls of the fixed shell and the movable shell of the buffer mechanism are made of stainless steel, and the surfaces of the fixed block and the pressure plate are coated with an anti-corrosion coating, which enhances the corrosion resistance and wear resistance of the buffer mechanism, enabling it to adapt to the complex environment of paint production and extend the service life of the components.

[0013] Preferably, the stirring blade is made of high-strength alloy material and is fixedly connected to the rotating rod by bolts.

[0014] By adopting the above technical solution, the stirring blade is made of high-strength alloy material, which improves the stirring intensity and material mixing uniformity. It is also fixedly connected to the rotating rod by bolts, which facilitates the disassembly, replacement and maintenance of the stirring blade and reduces equipment maintenance costs.

The sealing of the mounting hole is enhanced by the use of sealant, which prevents materials from seeping in and affecting the operation of the sensor.

[0017] Preferably, the annular heating plate is made of nickel-chromium alloy, and the inner wall of the mounting groove is covered with a heat insulation layer made of aluminum silicate cotton.

[0018] By adopting the above technical solution, the annular heating plate made of nickel-chromium alloy has high heating efficiency and good stability. The aluminum silicate cotton insulation layer on the inner wall of the installation tank can reduce heat loss and energy consumption, while avoiding the safety hazards caused by excessively high temperature on the outer wall of the reactor body.

[0019] Preferably, both the reactor body and the top cover are made of stainless steel, and a rubber sealing gasket is provided on the edge of the top cover, which is in close contact with the upper surface of the reactor body.

This reactor, used for producing ultra-high solids, low-viscosity waterborne epoxy modified resin coatings, improves cleaning efficiency and protects the inner wall of the reactor body by incorporating a buffer mechanism and a cleaning plate. In the buffer mechanism, a fixed shell is fixed to both ends of a rotating plate, and a movable shell is connected to a pressure plate inside the fixed shell via springs and a telescopic rod. One end of the movable shell is connected to the cleaning plate. When the rotating rod drives the rotating plate to rotate, the cleaning plate remains in contact with the inner wall of the reactor body under the elastic force of the spring. Simultaneously, the ball bearings on the side of the pressure plate roll within the groove of the movable shell, reducing friction between the movable and fixed shells. This structure avoids the hard contact between the traditional welded scraper and the inner wall, efficiently removes residual materials, extends the service life of the reactor body, eliminates the need for manual cleaning, and saves manpower.

[0022] 2. This reactor, used for producing ultra-high solids, low-viscosity waterborne epoxy modified resin coatings, achieves precise temperature control through the installation of an infrared sensor, a ring-shaped heating plate, and an external preset threshold controller. The infrared sensor is installed in the mounting hole of the rotating plate, detecting the temperature inside the reactor body in real time through a transparent wear-resistant plate and transmitting the signal to the external controller. When the temperature is below the preset threshold, the controller activates the ring-shaped heating plate; when the temperature reaches the threshold, the controller deactivates the ring-shaped heating plate. This automatic temperature control method solves the problem of unstable temperature in traditional devices, ensuring that the coating reacts at a suitable temperature, thus guaranteeing its performance and quality.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0026] Example 1: A reactor for producing ultra-high solids, low-viscosity waterborne epoxy modified resin coatings, referring to... Figure 1 , Figure 2 and Figure 3 The reactor includes a reactor body 1, a top cover 2 at the top of the reactor body 1, and a forward and reverse motor 3 installed on the top cover 2. The output end of the forward and reverse motor 3 passes through the top cover 2 and is fixedly connected to a rotating rod 4. The rotating rod 4 is rotatably connected inside the reactor body 1. Rotating plates 5 are fixedly connected to the upper and lower surfaces of the rotating rod 4. Buffer mechanisms 6 are provided at both ends of the two sets of rotating plates 5. Cleaning plates 7 are provided at the ends of the two sets of buffer mechanisms 6 away from each other. The cleaning plates 7 are in contact with the inner wall of the reactor body 1. The buffer mechanism 6 includes a fixed shell 601 and a movable shell 602. The fixed shell 601 is fixedly connected to the left and right ends of the rotating plates 5. The movable shell 602 is movably connected to the side of the fixed shell 601 and fixedly connected to the cleaning plate 7 at the end away from the fixed shell 601. A fixing block 603 is fixedly connected inside the fixed shell 601. The fixing block 603 is close to... A pressure plate 604 is fixedly connected to one end of the movable shell 602, and the pressure plate 604 is movably connected inside the movable shell 602. A spring 606 and a telescopic rod 605 are fixedly connected to the side of the pressure plate 604, and the spring 606 is sleeved on the surface of the telescopic rod 605. The other end of the spring 606 and the telescopic rod 605 is fixedly connected inside the movable shell 602. A stirring blade 8 is provided on the surface of the rotating rod 4. By setting a forward and reverse motor 3 to drive the rotating rod 4 and the stirring blade 8 to rotate, the material is fully stirred. The buffer mechanism 6 at both ends of the rotating plate 5 cooperates with the cleaning plate 7. Utilizing the elasticity of the spring 606 and the telescopic rod 605, the cleaning plate 7 is always in contact with the inner wall of the reactor body 1. This can effectively scrape off residual materials and avoid wear on the inner wall caused by hard contact, thus extending the service life of the equipment. At the same time, manual cleaning is not required, which improves production efficiency.

[0027] Reference Figure 1 , Figure 4 and Figure 5The rotating plate 5 has an internal mounting hole 9, and an infrared sensor 10 is fixedly connected inside the mounting hole 9. A transparent wear-resistant plate 11 is fixedly connected to the side of the mounting hole 9. The side wall of the reactor body 1 has an internal mounting groove 12, and an annular heating plate 13 is installed inside the mounting groove 12. The annular heating plate 13 and the infrared sensor 10 are both electrically connected to a preset threshold controller outside the reactor body 1. The external controller receives the detection signal from the infrared sensor 10 and controls the start / stop and heating power of the annular heating plate 13. A ball bearing 607 is rolledly connected to the side of the pressure plate 604. The movable shell 602 has an internal sliding groove 608, and the ball bearing 607 is rolledly connected inside the sliding groove 608. The infrared sensor 10 inside the moving plate 5 can monitor the temperature inside the reactor body 1 in real time through the transparent wear-resistant plate 11. Together with the annular heating plate 13 on the side wall of the reactor body 1 and the external preset threshold controller, a closed-loop temperature control system is formed to achieve precise control of the reaction temperature, ensuring that the ultra-high solids low viscosity waterborne epoxy modified resin coating reacts at a suitable temperature, thus guaranteeing product performance and quality. The ball bearings 607 on the side of the pressure plate 604 roll in conjunction with the sliding groove 608 inside the movable shell 602, reducing the frictional resistance between the fixed shell 601 and the movable shell 602 when the buffer mechanism 6 is working, making the extension and retraction of the cleaning plate 7 smoother, and improving the stability and service life of the buffer mechanism 6.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The inner walls of the fixed shell 601 and movable shell 602 of the buffer mechanism 6 are made of stainless steel. The fixed block 603 and pressure plate 604 are made of metal and coated with an anti-corrosion coating. The stirring blade 8 is made of high-strength alloy and is fixedly connected to the rotating rod 4 by bolts. The use of stainless steel for the inner walls of the fixed shell 601 and movable shell 602 of the buffer mechanism 6, along with the anti-corrosion coating on the surfaces of the fixed block 603 and pressure plate 604, enhances the corrosion resistance and wear resistance of the buffer mechanism 6, enabling it to adapt to the complex environment of paint production and extending the service life of components. The high-strength alloy material of the stirring blade 8 improves the stirring intensity and material mixing uniformity. Its fixed connection to the rotating rod 4 by bolts facilitates the disassembly, replacement, and maintenance of the stirring blade 8, reducing equipment maintenance costs.

[0029] Reference Figure 1 , Figure 4 and Figure 5The transparent wear-resistant plate 11 is made of polytetrafluoroethylene (PTFE) and is fixedly connected to the edge of the mounting hole 9 with sealant. The detection end of the infrared sensor 10 faces the inside of the reactor body 1. The annular heating plate 13 is made of nickel-chromium alloy. The inner wall of the mounting groove 12 is lined with a heat insulation layer made of aluminum silicate cotton. Both the reactor body 1 and the top cover 2 are made of stainless steel. The edge of the top cover 2 is provided with a rubber sealing gasket, which fits tightly against the upper surface of the reactor body 1. The transparent wear-resistant plate 11 made of PTFE ensures the detection accuracy of the infrared sensor 10 and effectively protects the sensor from direct contact with materials. The damage was mitigated by sealing the mounting hole 9 with sealant to prevent material from seeping in and affecting the sensor's operation. The annular heating plate 13, made of nickel-chromium alloy, has high heating efficiency and good stability. The aluminum silicate cotton insulation layer on the inner wall of the mounting groove 12 reduces heat loss and energy consumption, while also preventing the outer wall of the reactor body 1 from overheating and causing safety hazards. The reactor body 1 and the top cover 2 are made of stainless steel, which improves the overall corrosion resistance and structural strength of the equipment. The rubber sealing gasket on the edge of the top cover 2 ensures the reactor's airtightness, preventing material leakage and the entry of external impurities, ensuring a stable reaction environment, and improving product quality.

[0030] In this embodiment, by setting up a buffer mechanism 6 and a cleaning plate 7, the cleaning effect is improved and the inner wall of the reactor body 1 is protected. In the buffer mechanism 6, the fixed shell 601 is fixed to the left and right ends of the rotating plate 5, and the movable shell 602 is connected to the pressure plate 604 inside the fixed shell 601 through a spring 606 and a telescopic rod 605, and one end of the movable shell 602 is connected to the cleaning plate 7. When the rotating rod 4 drives the rotating plate 5 to rotate, the cleaning plate 7 is always in contact with the inner wall of the reactor body 1 under the elastic force of the spring 606. At the same time, the ball bearings 607 on the side of the pressure plate 604 roll in the groove 608 of the movable shell 602, reducing the friction between the movable shell 602 and the fixed shell 601. This structure avoids the hard contact between the traditional welded scraper and the inner wall, and can efficiently scrape off residual materials, extend the service life of the reactor body 1, eliminate the need for manual cleaning, and save manpower.

[0031] The implementation principle of this application embodiment is as follows: After the reactor body 1 and the top cover 2 are closed, the forward and reverse motor 3 at the top of the top cover 2 is started. Its output end passes through the top cover 2 and drives the fixedly connected rotating rod 4 to rotate inside the reactor body 1. The rotating plates 5 at the upper and lower ends of the rotating rod 4 and the stirring blades 8 on the surface rotate synchronously with the rotating rod 4. When the stirring blades 8 on the surface of the rotating rod 4 rotate, they stir the ultra-high solids low viscosity water-based epoxy modified resin coating material in the reactor body 1. At the same time, the forward and reverse motor 3 can realize forward and reverse rotation switching. By changing the stirring direction, the inertia of the directional flow of the material is broken, so that the material is mixed more evenly. When the rotating plate 5 rotates, the buffer mechanism 6 at its left and right ends moves synchronously. In the buffer mechanism 6, the fixed shell 601 rotates with the rotating plate 5, and the movable shell 602, under the elastic force of the spring 606, pushes the cleaning plate 7 to always be in contact with the inner wall of the reactor body 1, scraping away residual materials. At the same time, the ball bearings 607 on the side of the pressure plate 604 roll in the sliding groove 608 inside the movable shell 602, and with the guiding action of the telescopic rod 605, reduce the friction between the movable shell 602 and the fixed shell 601, ensuring a stable and efficient cleaning process. The infrared sensor 10 in the mounting hole 9 inside the rotating plate 5 detects the temperature inside the reactor body 1 in real time through the transparent wear-resistant plate 11 and transmits the signal to the external preset threshold controller. When the detected temperature is lower than the preset threshold, the controller controls the annular heating plate 13 in the mounting groove 12 on the side wall of the reactor body 1 to start heating; when the temperature reaches the preset threshold, the controller shuts off the annular heating plate 13, realizing automatic temperature control. The rubber sealing gasket on the edge of the top cover 2 is tightly fitted to the upper surface of the reactor body 1, preventing material leakage and external impurities from entering during the reaction and stirring process, maintaining the sealing and stability of the internal environment of the reactor body 1.
