Description

Technical Field

[0001] The invention relates to the technical field of reactors, in particular to a reactor for producing a film crosslinking agent. Background Art

[0002] Reactors are essential equipment used in a wide range of fields, including chemical, pharmaceutical, coating, and new materials processing. They are typically used for mixing, dissolving, dispersing, and polymerizing materials. They are primarily used for mixing, heating, cooling, reacting, volatilizing, crosslinking, and other chemical reactions. Traditional reaction processes are often complicated. Early reactors typically consisted of a simple metal body, heating and cooling components, a stirring system, and a sealed portion for heating or cooling. Their operating principle primarily relied on the body to maintain an internal temperature, making them suitable for general physical mixing or low-corrosive chemical reactions in enclosed spaces. However, with the development of chemical processes in specific industries, materials are increasingly reacting under increasingly complex conditions. With the increasing use of strong acids, strong bases, or highly corrosive organic solvents in modern chemical processes, reactors have placed higher demands on corrosion resistance, temperature control stability, spray uniformity, and ease of cleaning. Traditional metal bodies are susceptible to corrosion over long periods of use, leading to damage to the inner wall.

[0003] Traditionally, the reactor body is typically constructed of metal, without any effective corrosion protection or coating. Prolonged exposure to inorganic acids or organic solvents can cause the metal surface to corrode, leading to pitting, cracking, and even flaking, severely damaging the inner wall. This not only significantly shortens the equipment's lifespan but can also lead to leaks of chemicals and hazardous gases due to corrosion, perforation, or ruptures in the body. This not only pollutes the production environment but also poses serious safety risks to workers. Summary of the Invention

The scraper 410 and the extension frame 49 realize a precise scraping action, reducing waste and improving the quality of the coating.

[0022] See also Figure 1-Figure 4 Both solenoid valve 1 (6) and solenoid valve 3 (316) are three-way valves. Heater 21 is fixed to the surface of kettle body 2, and cooler 24 is placed on the top surface of base plate 1. The operating chamber of kettle body 2 is cylindrical and conical. Both solenoid valve 1 (6) and solenoid valve 3 (316) are three-way valves, enabling more precise control of fluid flow direction and flow rate, avoiding the instability of traditional valves during complex operations. The rational configuration of heater 21 and cooler 24 allows the reactor's operating environment to be rapidly adapted to meet diverse processing requirements.

[0023] See also Figure 1-Figure 3 、 Figure 6 One end of delivery pipe 1 35 is fixedly connected to the surface of delivery pipe 2 38 after it connects to pump 3 313. The other ends of return pipe 3 315 and return pipe 2 311 are both connected and fixed to the upper and lower ends of plate-and-frame filter 314 via flanges. The combination of return pipe 3 315, return pipe 2 311, and plate-and-frame filter 314 effectively separates solids and liquids, ensuring the purity of the reaction liquid. The return pipe design allows for the recycling of wastewater.

[0024] See also Figure 4 、 Figure 6-Figure 7 The motor 41 is fixed to the top of the bracket 7 by bolts. A limiting rod is sleeved inside the spring 420, one end of which is connected to the slider 415 and the other end is connected to the internal limiting structure sleeved on the connecting rod 418. The nozzle 413 is connected to the conical groove 411 in a movable limiting manner. The number of nozzles 413 and connecting rods 418 is multiple groups and is distributed circumferentially inside the groove 412 and the conical groove 411. The limiting rod is set in the spring 420 and cooperates with the limiting structure on the connecting rod 418 to effectively control the range of motion of the nozzle 413 and connecting rod 418, avoiding excessive spraying or offset, and ensuring the accuracy of the spraying angle and position. The nozzle 413 is connected to the conical groove 411 in a movable limiting manner, which improves the flexibility of the nozzle 413 adjustment. Multiple groups of nozzles 413 and connecting rods 418 are distributed circumferentially, so that the inner wall of the kettle body 2 can be covered in an all-round and uniform manner, greatly improving the density and consistency of the coating.

[0025] See also Figure 4 、 Figure 8 The surface of the gear 48 meshes with the surface of the rack 46, and the other end of the spring 420 is connected and fixed to the other end surface of the slide rail 419. There are three sets of bidirectional screw rods 47 and extension racks 49, which are all set inside the stirring rod 42 and distributed in an array. The scraper 410 fits tightly against the inner wall of the operating chamber of the kettle body 2. A heat-insulating sealing ring is provided at the sliding part between the stirring rod 42 and the extension rack 49. The rear end of the nozzle 413 is connected to a hose, and the other end of the hose is connected and fixed to the position near the bottom of the liquid discharge tank 9. The rack 46 meshes with the gear 48 to drive the bidirectional screw rod 47 to rotate, which can achieve precise telescopic control of the scraper 410, making the scraping action more stable and controllable. The bidirectional screw rods 47 and extension racks 49 adopt a three-set array distribution structure, so that the scraper 410 forms multi-point synchronous scraping on the inner wall of the kettle body 2, ensuring a more uniform coating distribution. The scraper 410 fits tightly against the inner wall of the kettle body 2 and can play a dual role in the process of removing the glaze layer and uniformly distributing the glaze slurry. A heat-insulating sealing ring is provided between the stirring rod 42 and the extension frame 49, which can effectively isolate high-temperature conduction and extend the service life of the mechanism.

[0026] Working Principle: When the kettle 2 needs to process inorganic acids or organic solvents, the container is first filled with a silica-rich glassy glaze slurry. Pump Three 313 is activated, and the glassy glaze slurry is transported to the interior of the drain tank 9 via the feed pipe 37. Simultaneously, Pump One 36 is activated, pumping water from the water tank 32 into the delivery pipe 1 35. The water flows along the delivery pipe 1 35 into the delivery pipe 2 38 and, guided by the spiral blade 39, flows closely against the outer wall of the delivery pipe 2 38, thereby cooling the glassy glaze slurry therein and maintaining a relatively low temperature. At this point, solenoid valve Three 316 opens, and the water flows back to the water tank 32 through the return pipe 4 317, completing the circulation.

[0027] After cooling, the vitreous glaze slurry is pressurized by pump 313 and pumped through a flexible hose to nozzle 413. By adjusting the angle of nozzle 413, the glaze slurry is evenly sprayed onto the inner wall of the operating chamber of kettle 2. Subsequently, heater 21 is activated, rapidly transferring heat to heat pipe 23. Thanks to the excellent thermal conductivity of heat pipe 23, the outer wall of the operating chamber rapidly heats up, transferring the heat to the inner wall of chamber 22.

[0028] Next, the hydraulic cylinder 44 and the motor 41 work in tandem: the hydraulic cylinder 44 pushes the movable frame 45 and the fixed hoop 416 downward, driving the downward pressure frame 417 and the connecting rod 418 to move axially. During this process, the connecting rod 418 first compresses the spring 420, while the nozzle 413 maintains a constant angle, always aiming at the inner wall of the kettle 2, ensuring uniform spraying of the glaze slurry. Simultaneously, the downward pressure of the movable frame 45 causes the rack 46 and gear 48 to engage and rotate, thereby driving the bidirectional screw 47. The bidirectional screw 47 is threadedly connected to the extension frame 49. Its rotation gradually retracts the extension frame 49, which in turn drives the scraper 410 to slowly move away from the inner wall of the operating chamber. At this point, the motor 41 drives the stirring rod 42 and scraper 410 to rotate, while the movable frame 45 and the fixed hoop 416 rotate synchronously, evenly spreading the glaze slurry across the inner wall of the kettle 2. As the heat is conducted by the heat pipe 23, the glassy glaze slurry sinters at high temperatures, forming a dense, smooth, and hard glassy coating that firmly bonds to the metal substrate. At the same time, the flow monitor 319 detects the glaze slurry delivery in real time. When the set threshold is reached, the electromagnetic valve 2 34 is automatically closed. At this time, the inorganic acid or organic solvent can be introduced into the kettle body 2 through the feed pipe 1 8 for processing.

[0029] After processing is complete, solenoid valve 1 (6) is opened, allowing the reaction product to exit the kettle 2 through reflux pipe 3 (315). Pump 2 (312) is then activated again, pumping water from the water tank 32 into delivery pipe 1 (35). The water enters delivery pipe 2 (38) and, under the control of solenoid valve 3 (316), is directed into the drain tank 9. Pump 2 (312) then pressurizes and delivers it to the nozzle 413 for cleaning the inner wall. Hydraulic cylinder 44 presses down on the movable frame 45, causing it to move downward. This downward movement of the movable frame 45 then drives the fixed hoop 416 downward. Simultaneously, the movement of the fixed hoop 416 also drives the lower pressing frame 417, which then moves the connecting rod 418 axially. This movement of the connecting rod 418 changes the spray angle of the nozzle 413, ensuring that the water not only rinses the inner wall of the kettle 2 but also cleans the surface of the stirring rod 42. The residual water and solvent then pass through solenoid valve 2 (34) and enter the plate-and-frame filter 314 for solid-liquid separation. The filtered clean water is sent back to the water tank 32 via the second pump 312 for recycling, and the waste residue can be cleaned by opening the filter when needed.

[0030] When producing different cross-linking agents, they may react with the glass glaze slurry due to different chemical elements, which may cause the cross-linking agent produced to be substandard. Therefore, different materials need to be replaced for corrosion protection. At the same time, in order to avoid interference with the chemical reaction caused by the residual glassy glaze slurry, the glaze layer needs to be removed. At this time, the heater 21 is started first, and the inner wall of the kettle body 2 is quickly heated through the heat pipe 23. Then, the cooler 24 is immediately started and rapid cooling is achieved through the heat pipe 23. The alternating action of hot and cold separates the glassy glaze slurry from the kettle body 2. Subsequently, the stirring rod 42 and the scraper 410 rotate to scrape off the detached glaze layer and push it to the bottom. At this time, water is delivered to the nozzle 413 by the pump 36 for secondary flushing. The flushing liquid is discharged into the plate and frame filter 314 together with the glaze slurry debris. After filtration, the clean water flows back to the water tank 32 for recycling. This not only prevents the performance of the cross-linking agent from being damaged, but also greatly improves the applicability and maintenance convenience of the kettle body 2. In addition, the nozzle 413 is made of corrosion-resistant material to adapt to the spraying environment of highly corrosive media such as inorganic acids and organic solvents. The inorganic acid and organic solvent are both in a viscous state during the processing process. When sprayed, they can stably adhere to the inner wall of the kettle body 2 without splashing onto the bottom end of the closing cover 3 of the kettle body 2 and the surface of the nozzle 413. By connecting and fixing multiple modular structures through this equipment, the equipment can be flexibly maintained and quickly replaced, which not only ensures the safety and efficiency of the production process, but also improves the adaptability under different process conditions.
