Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of concentration reactors for cyanuric acid production, specifically, to a concentration reactor for cyanuric acid production. Background Technology

[0002] Cyanuric acid, as an important chemical raw material, has wide applications in many fields. For example, it is an indispensable key component in the production of chloroisocyanuric acid products, pesticides, and coatings. In the production process of cyanuric acid, the concentration kettle is an extremely important piece of equipment. Its function is to concentrate the cyanuric acid solution through heating and other methods to obtain a cyanuric acid product that meets quality standards.

[0003] However, existing cyanuric acid concentration reactors have several problems. Firstly, the heating structure of these reactors is often fixed, making it impossible to flexibly adjust to different processing volumes. At smaller processing volumes, the fixed heating structure continuously outputs a large amount of heat, far exceeding actual needs. This not only wastes a significant amount of energy but also increases production costs. In the long run, this is extremely detrimental to the economic benefits and sustainable development of enterprises. Secondly, cleaning the reactor after cyanuric acid concentration is very inconvenient. Due to the complex internal structure of the reactor, cyanuric acid easily accumulates in corners and crevices, and conventional rinsing methods are insufficient to completely remove these residues. Over time, the residual cyanuric acid can affect the quality of subsequent products and may also cause equipment corrosion, shortening the lifespan of the concentration reactor. As market demand for cyanuric acid continues to change, the requirements for production efficiency and product quality are also increasing, making it difficult for existing concentration reactors to meet production needs.

[0004] Therefore, it is urgent to develop a cyanuric acid production concentration vessel that can adjust the heating structure according to the processing volume and is easy to clean. This is of great significance for improving cyanuric acid production efficiency, reducing costs, and ensuring product quality. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a concentration kettle for cyanuric acid production, which solves the technical problem that the heating structure of existing concentration kettles is often fixed and cannot be flexibly adjusted according to different processing volumes, resulting in a large waste of energy.

[0006] According to one aspect, at least one embodiment of this disclosure provides a concentration vessel for cyanuric acid production, comprising:

[0007] The vessel body and the outer frame, wherein the outer frame is disposed outside the vessel body;

[0008] A stirring assembly is disposed within the vessel body;

[0009] A heating assembly is disposed within the vessel body and the outer frame;

[0010] An exhaust pipe and a discharge assembly are provided, wherein the exhaust pipe is located at the top of the vessel body and the discharge assembly is located at the bottom of the vessel body;

[0011] The heating assembly includes a pair of sealing sleeves, each containing several heating tubes. The sealing sleeves are located inside the vessel body. A vertical screw is installed inside the outer frame, and the vertical screw is rotated by a motor. A lifting column is slidably connected inside the outer frame.

[0012] As a further technical solution, the vertical screw and the lifting column are connected by a threaded connection, a pair of connecting plates are provided on the top of the lifting column, a pair of shaft seals are provided on the top of the vessel body, and a pair of sliding rods are movably connected inside the shaft seals.

[0013] As a further technical solution, the upper end of each slide rod is connected to the bottom surface of the connecting plate, and a number of dispersing rods are fixedly connected between a pair of sealing sleeves, with the lower end of the slide rod connected to the dispersing rods.

[0014] As a further technical solution, one of the slide rods has a cavity inside, a water injection pipe is connected to the top of the slide rod, the water injection pipe is connected to the inside of the cavity, and a number of water spray holes are opened around the bottom of the cavity.

[0015] As a further technical solution, the stirring assembly includes a sealer, which is installed on the top of the vessel body. A drive motor is provided on the top of the sealer, and a stirring shaft bracket is provided at the output end of the drive motor. The stirring shaft bracket is rotatably connected to the sealer and the vessel body.

[0016] As a further technical solution, the discharge assembly includes a centralized pipe, which is located at the top of the vessel body. A telescopic cylinder is located at the bottom of the centralized pipe, and a sealing block is located at the output end of the telescopic cylinder. A discharge pipe is located on one side of the centralized pipe.

[0017] As a further technical solution, both the sealing sleeve and the dispersing rod are made of thermally conductive materials, and the sealing sleeve is in the form of a circular ring.

[0018] As a further technical solution, one end of the exhaust pipe has a bent structure, and the opening of the exhaust pipe faces vertically downward.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] 1. The beneficial effects of the heating component in this disclosure are that the heating tube inside the sealed sleeve quickly and evenly transfers heat through the heat-conducting material, the threaded fit between the vertical screw and the lifting column allows for flexible adjustment of the height of the sealed sleeve according to the processing volume, so that the heating range matches the solution volume, avoiding energy waste caused by the fixed heating structure when the processing volume changes, the connection between the sliding rod and the dispersing rod ensures the stability of the lifting of the sealed sleeve, and the water injection pipe and water spray hole are designed in the heating component to realize the combination of heating structure and rinsing function, which facilitates subsequent rinsing operations while adjusting the heating height, and improves the practicality of the equipment.

[0021] 2. In this disclosure, the beneficial effects of the stirring assembly are that the seal is installed on the top of the vessel to ensure the sealing of the concentration process and prevent gas leakage. The drive motor drives the stirring shaft to rotate inside the vessel, so that the cyanuric acid solution is constantly turned over during the heating process, promoting full contact with the heating components, avoiding local overheating or uneven heating, improving concentration efficiency and product quality. The rotation of the stirring shaft can also make the solution react more fully, reduce the concentration time, and improve production efficiency.

[0022] 3. The beneficial effects of the discharge component in this disclosure are that the centralized pipeline is set at the top of the vessel, and together with the telescopic cylinder and sealing block at the bottom, it can achieve precise control of the discharge process. During concentration, the sealing block tightly seals the pipeline to prevent material leakage. After concentration, the cylinder retracts and opens the pipeline, and the material is smoothly discharged through the discharge pipeline. The structure is simple and easy to control. At the same time, the rinsing function is integrated with the heating component. The inside of the vessel is thoroughly rinsed through the water spray hole in the slide rod, which effectively removes residual cyanuric acid, reduces equipment corrosion, extends service life, and improves the quality of products produced in subsequent production.

[0030] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0035] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] like Figures 1-5 As shown, a concentration vessel for cyanuric acid production is illustrated in one embodiment of this disclosure, comprising:

[0037] The vessel body 1 and the outer frame 2 are disposed outside the vessel body 1;

[0038] Stirring assembly 5, wherein the stirring assembly 5 is disposed in the vessel body 1;

[0039] Heating component 4 is disposed in the vessel body 1 and the outer frame 2;

[0040] The exhaust pipe 3 and the discharge assembly 6 are provided, wherein the exhaust pipe 3 is located at the top of the vessel body 1 and the discharge assembly 6 is located at the bottom of the vessel body 1;

[0041] The heating assembly 4 includes a pair of sealing sleeves 4-1, each containing several heating tubes 4-2. The sealing sleeves 4-1 are located inside the vessel body 1. A vertical screw 4-3 is installed inside the outer frame 2, and its rotation is controlled by a motor. A lifting column 4-4 is slidably connected inside the outer frame 2. The vertical screw 4-3 and the lifting column 4-4 are connected by a threaded connection. A pair of connecting plates 4-5 are provided at the top of the lifting column 4-4. A pair of shaft seals 4-6 are provided at the top of the vessel body 1. A pair of sliding rods 4-7 are movably connected inside the shaft seal 4-6. The upper ends of the sliding rods 4-7 are connected to the bottom surface of the connecting plate 4-5. Several dispersing rods 4-8 are fixedly connected between a pair of sealing sleeves 4-1. The lower ends of the sliding rods 4-7 are connected to the dispersing rods 4-8. A cavity 4-9 is opened inside one of the sliding rods 4-7. A water injection pipe 4-10 is connected to the top of the sliding rod 4-7. The water injection pipe 4-10 communicates with the inside of the cavity 4-9. Several water spray holes 4-11 are opened around the bottom of the cavity 4-9.

[0042] In some examples, during the concentration of cyanuric acid in a concentration vessel, a heating component 4 is designed to effectively heat the cyanuric acid inside the vessel and flexibly adjust the heating height according to the amount of material. This component can meet the heating requirements of cyanuric acid under different working conditions, improving the efficiency and quality of the concentration process. The component includes a pair of sealed sleeves 4-1, each containing several heating tubes 4-2. The sealed sleeves 4-1 are located inside the vessel body 1. When the heating tubes 4-2 are energized, they generate heat, which is transferred to the cyanuric acid inside the vessel body 1 through the sealed sleeves 4-1, thus heating the cyanuric acid. The design of the sealed sleeves 4-1 not only protects the heating tubes 4-2 but also prevents direct contact between the heating tubes 4-2 and the cyanuric acid, avoiding corrosion and other problems. A vertical screw 4-3, controlled by a motor, is installed inside the outer frame 2. A lifting column 4-4 is slidably connected inside the outer frame 2. The vertical screw 4-3 and the lifting column 4-4 are connected by a threaded connection. When the motor drives the vertical screw 4-3 to rotate... At this time, the lifting column 4-4 will move up and down along the outer frame 2. A pair of connecting plates 4-5 set on the top of the lifting column 4-4 are connected to the upper ends of a pair of sliding rods 4-7 that are movably fitted inside the shaft seal 4-6 at the top of the vessel body 1. The lower ends of the sliding rods 4-7 are connected to several dispersing rods 4-8 that are fixedly connected between a pair of sealing sleeves 4-1. In this way, by controlling the rotation of the vertical screw 4-3 by the motor, the lifting column 4-4, connecting plates 4-5, sliding rods 4-7 and sealing sleeves 4-1 can be driven to move up and down as a whole, thereby adjusting the position of the vessel body according to the vessel's movement. The heating height is adjusted according to the amount of cyanuric acid material to ensure uniform and efficient heating. One of the slide rods 4-7 has a cavity 4-9. The water injection pipe 4-10 connected to the top of the slide rod 4-7 is connected to the inside of the cavity 4-9. Several water spray holes 4-11 are opened around the bottom of the cavity 4-9. When it is necessary to clean or add water to the inside of the vessel, water can be injected into the cavity 4-9 through the water injection pipe 4-10. The water will be sprayed out from the water spray holes 4-11 to achieve the cleaning or water replenishment operation inside the vessel.

[0043] like Figures 1-5 As shown in the figure, the stirring assembly 5 in this embodiment includes a sealer 5-1, which is installed on the top of the vessel body 1. A drive motor 5-2 is provided on the top of the sealer 5-1, and a stirring shaft bracket 5-3 is provided at the output end of the drive motor 5-2. The stirring shaft bracket 5-3 is rotatably connected to the sealer 5-1 and the vessel body 1.

[0044] In some examples, during the distillation of cyanuric acid in a concentration vessel, a stirring assembly 5 is designed to ensure uniform heating and complete reaction of the cyanuric acid within the vessel, thereby improving distillation efficiency and product quality. This assembly is primarily used to stir the cyanuric acid within the concentration vessel. The assembly includes a seal 5-1 installed on the top of the vessel body 1. The seal 5-1 effectively prevents gas leakage during distillation, ensuring the sealing and safety of the distillation environment. A drive motor 5-2, located on top of the seal 5-1, serves as the power source for the stirring assembly 5, providing power for the stirring operation. The driving motor 5-2 is equipped with a stirring shaft 5-3 at its output end, which is rotatably connected to the seal 5-1 and the vessel body 1. When the driving motor 5-2 starts, it drives the stirring shaft 5-3 to rotate inside the concentration vessel, thereby achieving the stirring function of cyanuric acid. The rotation of the stirring shaft 5-3 can make the cyanuric acid continuously tumble inside the concentration vessel, promote full contact between the cyanuric acid and the heating components, make the cyanuric acid heated more evenly, and accelerate the distillation process. At the same time, stirring can also make the cyanuric acid react more fully during the distillation process, avoiding local overheating or incomplete reaction.

[0045] like Figures 1-5 As shown in the figure, the discharge component 6 in this embodiment includes a central pipe 6-1, which is located at the top of the vessel body 1. A telescopic cylinder 6-2 is located at the bottom of the central pipe 6-1. A sealing block 6-3 is located at the output end of the telescopic cylinder 6-2. A discharge pipe 6-4 is located on one side of the central pipe 6-1.

[0046] In some examples, after the material is concentrated in the concentrator, a discharge assembly 6 is designed to precisely control the discharge process and ensure its safety and controllability. This assembly is mainly used to effectively control the discharge operation of the concentrator. The assembly includes a central pipe 6-1 located at the top of the vessel body 1, which serves as the main channel for material discharge from the concentrator. A telescopic cylinder 6-2 is located at the bottom of the central pipe 6-1, and a sealing block 6-3 is installed at its output end. When the telescopic cylinder 6-2 is extended, the sealing block 6-3 fits tightly against the bottom of the central pipe 6-1, effectively blocking the pipe and preventing the material from flowing out of the concentrator prematurely, ensuring that the concentration process is not disturbed. When the material concentration is complete and discharge is required, the telescopic cylinder 6-2 is activated, causing the sealing block 6-3 to move downward, thereby opening the central pipe 6-1 and allowing the material to flow out smoothly. The discharge pipe 6-4 located on one side of the central pipe 6-1 provides a specific discharge path for the material, guiding the material from the central pipe 6-1 to subsequent collection or processing equipment.

[0047] For example, such as Figure 3 As shown, both the sealing sleeve 4-1 and the dispersing rod 4-8 are made of thermally conductive materials, and the sealing sleeve 4-1 is generally in the shape of a ring.

[0048] In some examples, thermally conductive materials enable faster and more uniform heat transfer, effectively providing heating while saving time and energy costs.

[0049] For example, such as Figure 1 As shown, one end of the exhaust pipe 3 has a bent structure, and the opening of the exhaust pipe 3 faces vertically downward.

[0050] In some examples, the downward-facing structure reduces the amount of condensate generated in the exhaust pipe 3, preventing backflow and increasing processing time.

[0051] In actual use: The cyanuric acid solution is injected into the vessel body 1. Based on the throughput, the motor inside the outer frame 2 controls the vertical screw 4-3 to rotate, causing the lifting column 4-4 to slide along the outer frame 2 via a threaded connection. The connecting plate 4-5 at the top of the lifting column 4-4 drives the sliding rod 4-7 to move within the shaft seal 4-6, thereby adjusting the height of the sealing sleeve 4-1 inside the vessel body 1. This positions the heating tube 4-2 in a suitable heating position, activating the heating tube 4-2 to heat the cyanuric acid solution. Simultaneously, the drive motor 5-2 drives the stirring shaft 5. Rotate -3 to stir the solution and promote uniform heating. The gas generated during the concentration process is discharged through the top-bent downward exhaust pipe 3 to reduce the backflow of condensate. After concentration is completed, control the telescopic cylinder 6-2 to retract, drive the sealing block 6-3 to move down, open the central pipe 6-1, and discharge the concentrated material through the discharge pipe 6-4. When rinsing is required, inject water into the cavity 4-9 in the slide rod 4-7 through the water injection pipe 4-10. The water is sprayed out from the bottom spray hole 4-11 to rinse the inside of the kettle body 1.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
