Description
Technical Field
[0001] This utility model relates to the technical field of powder coating production equipment, and in particular to an anti-sticking powder coating reactor. Background Technology
[0002] Powder coating reactors are key equipment in the powder coating production process. They are used in the chemical and building materials industries. Their main function is to promote the full reaction of various raw materials in a closed environment through stirring and heat exchange, thereby synthesizing powder coatings with anti-stick properties. In modern industrial production, the requirements for the quality and output of powder coatings are increasing, which makes the performance and stability of the reactors crucial.
[0003] Currently, traditional anti-sticking powder coating reactors typically rely on manual handheld sprayers for cleaning their inner walls. This method is not only inefficient and time-consuming, but also generates dust that can be inhaled by operators, posing a health hazard. To address these issues, existing technology utilizes built-in sprayers inside the reactor to achieve fully automated cleaning of the inner walls, significantly improving efficiency and reducing the health risks associated with manual operation. However, in practical use, it has been found that when the reactor agitates the powder coating, the high-speed rotation... The rotating agitator generates a large amount of dust, which easily adheres to the nozzle surface and water outlet. Over time, the dust accumulates and gradually clogs the nozzle's water outlet channel. Once the nozzle is clogged, the cleaning effect is greatly reduced. Not only can it not effectively remove residual coating from the inner wall of the reactor, but it also leads to a decrease in the cleanliness of the reactor, affecting the production quality of the next batch of coating. At the same time, frequent nozzle clogging requires operators to frequently disassemble and clean the nozzles, increasing the workload of equipment maintenance and downtime, and reducing production efficiency. Therefore, an anti-sticking powder coating reactor is proposed to solve the above problems. Utility Model Content

[0023] In this invention, when the inner wall of the reaction vessel needs to be cleaned, gas is injected into the expansion bladder through the gas injection valve, causing the rubber scraper to extend outward and adhere to the inner wall of the reaction vessel, thus enabling cleaning in conjunction with the cleaning equipment. After the gas is discharged, the rubber scraper returns to its original position under the rebound of the return spring. This ensures that the normal stirring efficiency is not affected and extends the service life of the rubber scraper. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: an anti-sticking powder coating reactor, including a reaction tank 1 and a stirring rod 4. A sealing cover 2 is fixedly connected to the top of the reaction tank 1. The sealing cover 2 is used to ensure the sealing of the reaction tank 1 and prevent dust leakage. A protective mechanism 3 is provided on the top of the sealing cover 2. The protective mechanism 3 can prevent the equipment from being affected by dust and causing blockage. A cleaning mechanism 5 is provided inside the reaction tank 1. The cleaning mechanism 5 can remove residual dust on the inner wall of the reaction tank 1. A driving mechanism 6 is provided on the top of the sealing cover 2. The driving mechanism 6 can drive the powder coating to be fully stirred. An operating mechanism 7 is provided on the top of the sealing cover 2. The operating mechanism 7 facilitates manual maintenance of the internal equipment. A heating mechanism 9 is provided on the outer wall of the reaction tank 1. The heating mechanism 9 can increase the temperature inside the reaction tank 1.
[0033] The protective mechanism 3 includes multiple mounting slots 301, all located around the top of the sealing cover 2. These slots provide operating space for the protective mechanism 3. Support plates 303 are fixedly connected to the inner sides of each mounting slot 301, and cylinders 304 are fixedly connected to the tops of each support plate 303. The cylinders 304 are mounted within the mounting slots 301 via the support plates 303. One end of each cylinder 304 passes through the top of the support plate 303 and is fixedly connected to a nozzle 305. Driven by the cylinders 304, the nozzle 305 can slide up and down. A protective cylinder 302 is connected to the bottom inner side of the mounting slot 301. The nozzle slides within the protective cylinder 302, which is connected to the sealing cover 2, allowing the nozzle 305 to extend through the protective cylinder 302 into the reaction vessel 1. A magnetic block 306 is fixedly connected to the outer wall of the protective cylinder 302, and a water pipe 307 is connected to the outer wall of the nozzle 305. A connecting plate 308 is fixedly connected to the wall. A rotating shaft 309 is rotatably connected to the inner side of the connecting plate 308. A torsion spring 311 is fixedly connected to the outer wall of the rotating shaft 309. In order to prevent dust from adhering to the end of the nozzle 305 during the processing and stirring process, causing outlet blockage, when the nozzle 305 retracts upward, the sealing plate 310 seals the protective cylinder 302 under the rebound of the torsion spring 311 to prevent dust from entering. The sealing plate 310 is also attracted by the magnetic block 306 to improve stability. The bottom of the rotating shaft 309 is fixedly connected to the sealing plate 310. A protective component 312 is provided at the bottom of the nozzle 305. The protective component 312 includes a wear-resistant sleeve 3121, which is fixedly connected to the bottom of the nozzle 305. A nozzle 3122 is opened at the bottom of the wear-resistant sleeve 3121. The wear-resistant sleeve 3121 is installed on the nozzle 305, so that the nozzle 305 can be protected during operation.
[0034] Specifically, mounting slots 301 are evenly spaced around the top edge of the sealing cover 2. These slots provide the necessary operating space for the protective mechanism 3, ensuring smooth operation. Support plates 303 are installed inside each mounting slot 301, providing a stable foundation for subsequent components. Cylinders 304 are mounted in the mounting slots 301 via the support plates 303. One end of each cylinder 304 penetrates the top of the support plate 303 and is fixedly connected to the nozzle 305. Driven by the cylinders 304, the nozzle 305 can slide up and down, enabling precise spraying within the reaction tank 1. The bottom inner side of the mounting slot 301 communicates with the protective cylinder 302, allowing the nozzle 305 to slide within it. The protective cylinder 302 is connected to the sealing cover 2, ensuring... The nozzle 305 can smoothly extend into the interior of the reaction vessel 1. To further enhance the protective effect, when the nozzle 305 retracts upward, the rebound force of the torsion spring 311 causes the sealing plate 310 to seal the protective cylinder 302, effectively preventing dust from entering the interior of the protective cylinder 302. To improve the stability of the seal, the magnetic block 306 also attracts the sealing plate 310. The bottom of the rotating shaft 309 is fixedly connected to the sealing plate 310, ensuring the reliability of the seal. A protective component 312 is provided at the bottom of the nozzle 305. This component includes a wear-resistant sleeve 3121, which is fixed at the bottom of the nozzle 305. The bottom of the wear-resistant sleeve 3121 has a nozzle 3122. The wear-resistant sleeve 3121 is installed on the nozzle 305. In this way, the nozzle 305 can be effectively protected during operation and use, extending its service life.
[0035] Reference Figure 4 and Figure 5The cleaning mechanism 5 includes two mounting plates 501, both of which are fixedly connected to the left and right ends of the stirring rod 4. The mounting plates 501 are installed at both ends of the stirring rod 4. Each mounting plate 501 has a mounting cavity 502 on its opposite side. The mounting plate 501 contains a T-shaped mounting cavity 502. Each adjacent side of the two mounting cavities 502 is connected to an air injection valve 505. The opposite ends of the two air injection valves 505 penetrate the outer wall of the mounting plate 501 and are connected to an expansion bladder 506. The expansion bladder 506 is installed inside the mounting cavity 502 and communicates with the outer air injection valve 505. Each opposite side of the two expansion bladders 506 is fixedly connected to a rubber scraper 503. Each opposite side of the two rubber scrapers 503 is fixedly connected to multiple return springs 504. When it is necessary to clean the inside of the reaction tank 1... When cleaning the wall, gas is injected into the expansion bladder 506 through the gas injection valve 505, causing the rubber scraper 503 to extend outward and adhere to the inner wall of the reaction tank 1, thus cooperating with the cleaning equipment for cleaning. After the gas is discharged, the rubber scraper 503 returns to its original position under the rebound of the return spring 504. This does not affect the normal stirring efficiency and extends the service life of the rubber scraper 503. The top of the mounting plate 501 is provided with a mounting assembly 507, which includes two fixing bolts 5072. The two fixing bolts 5072 are threaded to the adjacent side of the mounting plate 501. The far end of the two fixing bolts 5072 passes through the outer wall of the mounting plate 501 and is threaded to the fixing plate 5071. The rubber scraper 503 is fixed by the fixing plate 5071 and the fixing bolts 5072.
[0036] Specifically, mounting plates 501 are connected to the left and right ends of the stirring rod 4, ensuring structural stability. Dedicated mounting cavities 502 are provided on the relatively distant sides of the two mounting plates 501. These mounting cavities 502 are T-shaped to accommodate specific structural requirements. Adjacent to the mounting cavities 502, each is connected to an injection valve 505. The relatively distant ends of these injection valves 505 penetrate the outer wall of the mounting plate 501 and communicate with the expansion bladder 506. The expansion bladder 506 is installed inside the mounting cavity 502 and remains connected to the outer injection valve 505. Rubber scrapers 503 are fixedly connected to the relatively distant sides of the two expansion bladders 506. When it is necessary to adjust the reaction vessel... When cleaning the inner wall of the reaction vessel 1, the operator can inject gas into the expansion bladder 506 through the gas injection valve 505, causing the rubber scraper 503 to extend outward and fit tightly against the inner wall of the reaction vessel 1, thereby cooperating with the cleaning equipment for effective cleaning. After the gas is discharged, the rubber scraper 503 automatically resets under the action of the return spring 504. This not only does not affect the normal stirring efficiency, but also extends the service life of the rubber scraper 503. In addition, the top of the mounting plate 501 is also equipped with a mounting and dismounting assembly 507. Through the cooperation of the fixing plate 5071 and the fixing bolt 5072, the rubber scraper 503 can be effectively fixed to ensure its stability and reliability during use.
[0037] Reference Figure 1 The drive mechanism 6 includes a mounting bracket 601, which is fixedly connected to the top of the sealing cover 2. A servo motor 602 is fixedly connected to the top of the mounting bracket 601, and the output end of the servo motor 602 is fixedly connected to the top of the stirring rod 4. The operation mechanism 7 includes a cover door 701, which is rotatably connected to the front top of the sealing cover 2. An observation window 702 is fixedly connected to the top of the cover door 701. The heating mechanism 9 includes a heat insulation layer 901, which is fixedly connected to the outer wall of the reaction tank 1. A heater 902 is fixedly connected to the front side of the outer wall of the heat insulation layer 901. Mounting parts 8 are fixedly connected to all four sides of the outer wall of the reaction tank 1. A temperature sensor 10 is fixedly connected to the top of the sealing cover 2.
[0038] Specifically, a servo motor 602 is fixed to the top of the mounting bracket 601. As the core part of the drive mechanism 6, the output end of the servo motor 602 is fixed to the top of the stirring rod 4 to ensure that the stirring rod 4 can rotate efficiently. The cover 701 is connected to the top front side of the sealing cover 2 for easy opening and closing by the operator. The top of the cover 701 is also designed with an observation window 702, which allows the operator to observe the condition inside the reaction tank 1 without opening the cover 701. The heating mechanism 9 consists of an insulation layer 901 and a heater 902. The insulation layer 901 is fixedly connected to the outer wall of the reaction tank 1 to maintain a stable temperature inside the reaction tank 1. The heater 902 is fixed to the front side of the outer wall of the insulation layer 901 to provide the necessary heat to maintain the temperature conditions required for the chemical reaction. The temperature sensor 10 can monitor the temperature inside the reaction tank 1 in real time to ensure that the reaction process is carried out at the optimal temperature.
[0039] Working principle: First, driven by cylinder 304, nozzle 305 can slide in protective cylinder 302. Protective cylinder 302 is connected to sealing cover 2, allowing nozzle 305 to extend through protective cylinder 302 into reaction tank 1. To prevent dust from adhering to the end of nozzle 305 during processing and stirring, causing outlet blockage, when nozzle 305 retracts upward, sealing plate 310, under the rebound of torsion spring 311, seals protective cylinder 302 to prevent dust from entering. The sealing plate 310 is also attracted by magnetic block 306 to improve stability. Wear-resistant sleeve 3121 is installed on nozzle 305, thus protecting nozzle 305 during operation.
[0040] Furthermore, when it is necessary to clean the inner wall of the reaction tank 1, gas is injected into the expansion bladder 506 through the gas injection valve 505, causing the rubber scraper 503 to extend outward and adhere to the inner wall of the reaction tank 1, thus cooperating with the cleaning equipment for cleaning. After the gas is discharged, the rubber scraper 503 returns to its original position under the rebound of the return spring 504. This does not affect the normal stirring efficiency and extends the service life of the rubber scraper 503. The rubber scraper 503 can be quickly disassembled and fixed periodically through the fixing plate 5071 and the fixing bolt 5072.
