Abstract
Description
Technical Field
[0001] This utility model relates to the field of chelating agent production technology, and in particular to a reaction vessel for chelating agent production. Background Technology
[0002] Chelating agents are a class of compounds that can form stable complexes with metal ions. These compounds typically have multiple coordination sites, enabling them to "chelate" metal ions within their structure through coordination interactions, thereby affecting the chemical properties and bioavailability of the metal ions. With increasing environmental awareness and rising demands for heavy metal pollution control, chelating agents, as an important chemical substance, are widely used in medicine, agriculture, industry, and environmental protection. Chelating agents can effectively form stable complexes with metal ions, reducing their toxicity and promoting their excretion from organisms or the environment. Therefore, a reaction vessel for the production of chelating agents is needed.
[0003] Most traditional reactors lack effective cleaning mechanisms, leading to the accumulation of residues on the inner walls. This not only affects the uniformity of mixing in subsequent production but may also cause product quality instability, increasing uncertainty in the production process. During the reaction, the internal temperature of traditional reactors is prone to becoming too high, potentially causing instability or side reactions. This not only affects product yield and quality but may also damage the equipment, increasing safety hazards. Furthermore, traditional reactors typically require manual collection of the reaction products. During operation, workers often need to bend over and hold collection tools, which not only increases the workload for workers but also consumes a lot of time, reducing work efficiency. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a reaction vessel for the production of chelating agents.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A reaction vessel for producing a chelating agent includes a water tank. An outer cylinder is fixed to the top of the water tank, and an inner cylinder is disposed inside the outer cylinder, with a cavity structure between the outer and inner cylinders. A cooling mechanism for cooling the outer and inner cylinders is disposed inside the water tank. A cylinder cover is disposed on the top of the outer cylinder. Multiple fixing mechanisms for fixing the cylinder cover are arranged in a circular pattern at equal intervals on the outer side wall of the outer cylinder. A rotating shaft is rotatably connected to the bottom center of the cylinder cover. A motor is fixed to the top of the cylinder cover, and the output shaft of the motor is fixed to the rotating shaft. A pressure relief valve is installed on the top of the cylinder cover. A stirring and chelating mechanism is disposed inside the inner cylinder. The mixing mechanism for the raw materials includes multiple cleaning mechanisms inside the inner cylinder for cleaning the inner wall of the inner cylinder. A circular seat is slidably connected to the inner wall of the inner cylinder and is located below the rotating shaft. A lifting mechanism for raising and lowering the circular seat is provided at the bottom of the circular seat. During use, the cooling mechanism design can promptly control the temperature of the inner cylinder within a suitable range, avoiding instability or side reactions caused by excessive temperature during the reaction process, thus ensuring product quality. The lifting mechanism can raise the circular seat, making it convenient for staff to collect the final product, reducing the complexity of manual operation and improving work efficiency.
[0007] Preferably, the cooling mechanism includes a water pump fixed to the bottom of the water tank, with the pump outlet communicating with the cavity. Multiple connecting pipes are arranged in a circular pattern at equal intervals on the outer wall of the outer cylinder. One end of each connecting pipe communicates with the cavity, and the other end communicates with the water tank. An installation hole is provided at the bottom of the water tank. A semiconductor cooling chip is fixed to the inner wall of the installation hole. Multiple first fins are fixed in a circular pattern at equal intervals on the cold end of the semiconductor cooling chip, and multiple second fins are fixed in a circular pattern at equal intervals on the hot end of the semiconductor cooling chip. The water pump continuously draws cold water into the cavity between the outer and inner cylinders, cooling the surface of the inner cylinder. The cooling process involves filling the cavity with cold water, then allowing excess water to re-enter the water tank through multiple connecting pipes. This removes the heat generated during the reaction of the chelating agent raw materials from the inner cylinder, preventing excessively high temperatures inside the inner cylinder that could lead to unstable reactions or side reactions. This method not only improves product yield and quality and prevents damage to equipment but also reduces safety hazards. When the semiconductor cooling chip is energized, its cold end temperature drops rapidly, causing the surface temperature of multiple first fins to decrease rapidly until the water temperature reaches the specified level. At this point, the water entering the water tank is cooled again, allowing for water circulation and saving water resources.
[0008] Preferably, the fixing mechanism includes a U-shaped frame fixed to the outer wall of the outer cylinder. An L-shaped plate is rotatably connected to the inner wall of the U-shaped frame. A groove is formed in the top of the L-shaped plate. A slider is slidably connected to the inner wall of the groove. A threaded rod is rotatably connected to the top of the slider, and one end of the threaded rod passes through the top of the L-shaped plate. A threaded hole is formed in the top of the L-shaped plate, and the threaded hole and the threaded rod are adapted to each other. By rotating multiple L-shaped plates, the inner bottom of multiple L-shaped plates are in contact with the top of the cylinder cover. By rotating multiple threaded rods, multiple sliders are moved downward along multiple grooves until multiple sliders are tightly fitted with the top of the cylinder cover, thus fixing the cylinder cover and the inner cylinder. The opposite operation can release the fixing of the cylinder cover and the inner cylinder.
[0009] Preferably, the stirring mechanism includes multiple sets of stirring rods, which are evenly spaced and circularly fixed to the side wall of the rotating shaft. The cleaning mechanism includes an arc-shaped scraper, which is disposed on the inner side wall of the inner cylinder, and one side of the arc-shaped scraper is fixed to one of the stirring rods. The lifting mechanism includes multiple hydraulic push rods, which are evenly spaced and circularly disposed at the top of the water tank, and one end of each hydraulic push rod is fixed to the bottom of the inner cylinder. The output ends of each hydraulic push rod are fixed to the bottom of the circular seat. The drive motor drives the rotating shaft to rotate, which in turn drives the multiple stirring rods to rotate simultaneously, thus stirring the raw materials for chelating agent production. At the same time, the rotation of the multiple stirring rods drives the multiple arc-shaped scrapers to rotate simultaneously, scraping and cleaning the inner wall of the inner cylinder, preventing the raw materials for chelating agent production from adhering to the inner side wall of the inner cylinder. This allows the raw materials for chelating agent production to be fully mixed, improving the stability of the product.
[0010] The beneficial effects of this utility model are as follows:
[0011] 1. During use, this device, through the combination of a stirring mechanism and a cleaning mechanism, can fully stir the chelating agent raw materials, ensuring thorough mixing of the materials and improving the consistency and stability of the product.
[0012] 2. The cooling mechanism design effectively controls the temperature of the inner cylinder within a suitable range, preventing instability or side reactions caused by excessively high temperatures during the reaction process, thus ensuring product quality.
[0013] 3. The lifting mechanism can raise the circular base, making it easier for staff to collect the final product, reducing the complexity of manual operation and improving work efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1 - Figure 5A reaction vessel for producing a chelating agent includes a water tank 1. An outer cylinder 2 is fixed to the top of the water tank 1. An inner cylinder 18 is disposed inside the outer cylinder 2, and a cavity structure exists between the outer cylinder 2 and the inner cylinder 18. This cavity is mainly used for water circulation, effectively reducing the surface temperature of the inner cylinder 18, controlling the heat during the reaction process, and preventing excessively high internal temperatures that could lead to reaction instability or side reactions. A cooling mechanism for cooling the outer cylinder 2 and the inner cylinder 18 is provided inside the water tank 1. A cylinder cover 3 is provided on the top of the outer cylinder 2. Multiple fixing mechanisms for fixing the cylinder cover 3 are arranged in a circular pattern at equal intervals on the outer side wall of the outer cylinder 2. A rotating shaft 15 is rotatably connected to the bottom center of the cylinder cover 3. A motor 7 is fixed to the top of the cylinder cover 3, and the output shaft of the motor 7 is fixed to the rotating shaft 15. A pressure relief valve 8 is installed on the top of the cylinder cover 3. A stirring mechanism for stirring the chelating agent raw materials is provided inside the inner cylinder 18. The device 8 is equipped with multiple cleaning mechanisms for cleaning the inner wall of the inner cylinder 18. A circular seat 14 is slidably connected to the inner wall of the inner cylinder 18. The circular seat 14 is located inside the inner cylinder 18 and its bottom is connected to a lifting mechanism. Its main function is to move up and down through the lifting mechanism so that the final product can be scraped into the collection container after production. This design makes operation more convenient, reduces the labor intensity of workers, and improves work efficiency. The circular seat 14 is located below the rotating shaft 15, and a lifting mechanism for raising and lowering the circular seat 14 is provided at the bottom of the circular seat 14. During the use of this device, the temperature of the inner cylinder 18 can be controlled within a suitable range in a timely manner through the cooling mechanism design, avoiding instability or side reactions caused by excessive temperature during the reaction process, ensuring product quality. The lifting mechanism can raise the circular seat 14, making it convenient for workers to collect the final product, reducing the complexity of manual operation and improving work efficiency.
[0022] In this invention, the cooling mechanism includes a water pump 9, which is fixed to the bottom of the water tank 1, and its outlet is connected to the cavity. Multiple connecting pipes 4 are arranged in a circular pattern at equal intervals on the outer wall of the outer cylinder 2. One end of each connecting pipe 4 is connected to the cavity, and the other end is connected to the water tank 1. An installation hole is provided at the bottom of the water tank 1, and a semiconductor cooling chip 11 is fixed to the inner wall of the installation hole. The semiconductor cooling chip 11 rapidly reduces the temperature of its cold end through the circulation of cooling water, thereby lowering the water temperature in the water tank 1 to a specified temperature, thus improving the cooling effect. This helps to improve the overall cooling efficiency and ensure that the temperature during the reaction process is controlled within a reasonable range. Multiple first fins 12 are fixed in a circular pattern at equal intervals on the cold end of the semiconductor cooling chip 11, and multiple second fins are fixed in a circular pattern at equal intervals on the hot end of the semiconductor cooling chip 11. 13. The driving water pump 9 continuously pumps cold water into the cavity between the outer cylinder 2 and the inner cylinder 18 to cool the surface of the inner cylinder 18. After the cavity is filled with cold water, the excess water re-enters the water tank 1 through multiple connecting pipes 4. This removes the heat generated by the chelating agent raw materials during the reaction process from the inner cylinder 18, preventing the internal temperature of the inner cylinder 18 from becoming too high, which could lead to unstable reaction or side reactions. This operation not only improves the product yield and quality and prevents damage to the equipment, but also reduces safety hazards. When the semiconductor cooling chip 11 is energized, its cold end temperature drops rapidly, which in turn causes the surface temperature of the multiple first fins 12 to drop rapidly until the water temperature is reduced to the specified temperature. At this point, the water entering the water tank 1 is cooled again, allowing the water to be circulated and saving water resources.
[0023] In this utility model, the fixing mechanism includes a U-shaped frame 5, which is fixed to the outer wall of the outer cylinder 2. An L-shaped plate 6 is rotatably connected to the inner wall of the U-shaped frame 5. A groove 19 is provided on the top of the L-shaped plate 6. A slider 20 is slidably connected to the inner wall of the groove 19. A threaded rod 21 is rotatably connected to the top of the slider 20, and one end of the threaded rod 21 passes through the top of the L-shaped plate 6. A threaded hole is provided on the top of the L-shaped plate 6, and the threaded hole and the threaded rod 21 are adapted to each other. By rotating multiple L-shaped plates 6, the inner bottom of multiple L-shaped plates 6 is in contact with the top of the cylinder cover 3. By rotating multiple threaded rods 21, multiple sliders 20 are moved downward along the direction of multiple grooves 19 until multiple sliders 20 are tightly fitted with the top of the cylinder cover 3, thus completing the fixing of the cylinder cover 3 and the inner cylinder 18. By reversing the operation, the fixing of the cylinder cover 3 and the inner cylinder 18 can be released.
[0024] In this invention, the stirring mechanism includes multiple sets of stirring rods 16, which are evenly spaced and circularly fixed to the side wall of the rotating shaft 15. The cleaning mechanism includes an arc-shaped scraper 17, which is disposed on the inner side wall of the inner cylinder 18. Combined with the stirring mechanism, the arc-shaped scraper 17's main function is to clean the inner wall of the inner cylinder 18, preventing the raw materials for chelating agent production from adhering to the inner wall. Through coordinated operation with the movement of the stirring rods 16, the arc-shaped scraper 17 can effectively avoid material waste, ensure thorough mixing of raw materials, and improve product stability and quality. One side of the arc-shaped scraper 17 is fixed to one set of stirring rods 16. The lifting mechanism includes... Multiple hydraulic push rods 10 are evenly spaced and circularly arranged at the top of the water tank 1, with one end of each push rod fixed to the bottom of the inner cylinder 18. The output ends of the push rods 10 are fixed to the bottom of the circular seat 14. The drive motor 7 drives the rotating shaft 15 to rotate, which in turn drives multiple stirring rods 16 to rotate simultaneously, stirring the raw materials for chelating agent production. At the same time, the rotation of the stirring rods 16 drives multiple arc-shaped scrapers 17 to rotate simultaneously, scraping and cleaning the inner wall of the inner cylinder 18 to prevent the raw materials for chelating agent production from adhering to the inner wall of the inner cylinder 18. This ensures that the raw materials for chelating agent production are fully mixed, improving the stability of the product.
[0025] Working Principle: During use, a large amount of cold water is pre-filled into the water tank 1. The raw materials for chelating agent production are then placed inside the inner cylinder 18. After completion, the cylinder cover 3 is closed and fixed. During fixing, multiple L-shaped plates 6 are rotated so that the inner bottom of each L-shaped plate 6 contacts the top of the cylinder cover 3. Multiple threaded rods 21 are rotated to drive multiple sliders 20 to move downwards along multiple grooves 19 until all sliders 20 are tightly fitted to the top of the cylinder cover 3, thus sealing the interior of the inner cylinder 18. During production, the power switch of the motor 7 is turned on, driving the motor 7 to rotate the shaft 15. The rotation of the stirring rods 16 simultaneously stirs the raw materials for chelating agent production. Simultaneously, the rotation of the stirring rods 16 drives the rotation of multiple arc-shaped scrapers 17, scraping and cleaning the inner wall of the inner cylinder 18 to prevent the raw materials from adhering to the inner wall. This ensures thorough mixing of the raw materials and improves product stability. During production, the power switches for the water pump 9 and the semiconductor cooling chip 11 are turned on, driving the water pump 9 to continuously pump cold water into the cavity between the outer cylinder 2 and the inner cylinder 18, cooling the surface of the inner cylinder 18. After the cavity is filled with cold water, the excess water re-enters the water tank 1 through multiple connecting pipes 4. This removes the heat generated during the reaction of the chelating agent raw materials from the inner cylinder 18, preventing excessively high temperatures inside the inner cylinder 18 that could lead to unstable reactions or side reactions. This operation not only improves product yield and quality and prevents equipment damage but also reduces safety hazards. When the semiconductor cooling chip 11 is energized, its cold end temperature drops rapidly, causing the surface temperature of the multiple first fins 12 to drop rapidly until the water temperature reaches the specified level. At this point, the water enters the water tank 1. The water is cooled again, allowing it to be recycled and conserving water resources. After the reaction is complete, multiple threaded rods 21 are rotated in the opposite direction, causing multiple sliders 20 to enter multiple grooves 19 respectively. This releases the outer cylinder 2 and the cap 3, removes the cap 3 from the top of the inner cylinder 18, and drives multiple hydraulic push rods 10 to move the circular seat 14 upward until the circular seat 14 and the top of the inner cylinder 18 are flush. This makes it easier for workers to scrape the final product into the collection container, eliminating the need for workers to bend over and use collection tools to collect the product one by one inside the inner cylinder 18, saving time and improving work efficiency.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
