[0028] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0029] Please see Figure 1-4 The present invention provides the following technical solution:

[0030] Ammonia water low-temperature conveying anti-clogging device includes:

[0031] Framework 1;

[0032] The first conveying tank 2 is fixedly connected to one side of the upper end of the frame 1;

[0033] The second conveying tank 3 is fixedly connected to the other side of the upper end of the frame 1;

[0034] Box 6 is connected to the upper end of frame 1. The upper end of box 6 is connected to top plate 10, and the lower end of box 6 is connected to air inlet 7.

[0035] The anti-blocking mechanism includes a constant temperature tank 8, a heater 9, an opening 11, and a stirring component. The constant temperature tank 8 is fitted inside the box body 6. The heater 9 is fixedly connected to the circumferential surface of the constant temperature tank 8. The opening 11 is opened on the inner wall of the box body 6, with the upper end of the opening 11 penetrating through the top plate 10 and the lower end penetrating through the bottom of the box body 6. The stirring component is set inside the constant temperature tank 8 to prevent crystallization when ammonia is transported at low temperature.

[0036] In a specific embodiment of this utility model, when ammonia water needs to be transported at low temperature, the ammonia water enters the constant temperature tank 8 from the first transport tank 2 through the first connecting pipe 21; in this way, a stable transport path is provided for the subsequent anti-crystallization treatment, ensuring that the ammonia water flows in a controlled environment.

[0037] When the constant temperature tank 8 is installed inside the box 6 and a heater 9 is fixedly connected to its circumferential surface, the heater compensates for the temperature of the ammonia water inside the constant temperature tank; in this way, the ammonia water crystallizes due to excessively low temperature, thereby avoiding blockage of the conveying pipeline and ensuring the continuity and stability of the conveying process.

[0038] When the stirring component is installed inside the constant temperature tank 8, and includes a first rotating rod 12, a first stirring blade 13 and a driving assembly, the driving assembly drives the first rotating rod to rotate, thereby driving the stirring blade to continuously stir the ammonia water; in this way, the ammonia water is kept in a uniform flow state during the transportation process, further preventing the occurrence of local crystallization.

[0039] When the opening 11 is made on the inner wall of the box 6 and extends through the top plate 10 and the bottom of the box 6, the stirring component is installed and connected to the transmission through the opening; in this way, the stable operation of the stirring structure is ensured, and it is convenient for later maintenance and repair.

[0040] When the lower part of the constant temperature tank 8 is connected to the air inlet 7 and connected to the external temperature control system, cold or hot air can enter the interior of the tank according to the actual temperature requirements; in this way, precise temperature control of the working environment of the constant temperature tank can be achieved, enhancing the adaptability and adjustment capability of the device.

[0041] In this way, when ammonia water enters the constant temperature tank 8 from the first conveying tank 2, it undergoes anti-crystallization treatment under the synergistic action of the heater 9 and the stirring component, and is then conveyed to the second conveying tank 3 through the second connecting pipe 22. Thus, when the equipment encounters low temperature environment or long-term conveying during operation, it can still effectively prevent ammonia water from crystallizing and clogging the pipeline, ensuring the safe, stable and efficient operation of the conveying system.

[0042] Please refer to the details. Figure 1-4 The stirring component includes two sets of first rotating rods 12, first stirring blades 13, first gears 14, parallelogram openings 15, and a drive assembly. The first rotating rods 12 are rotatably connected to the side end of the opening 11. The first stirring blades 13 are fixedly connected to the circumferential surface of the first rotating rods 12. The first gears 14 are fixedly connected to the upper end of the first rotating rods 12. The parallelogram openings 15 are opened at the side end of the first stirring blades 13. The drive assembly is located at the upper end of the opening 11 to realize the rotation of the first rotating rods 12.

[0043] In this embodiment: when the stirring component includes two sets of first rotating rods 12, first stirring blades 13, first gears 14, parallelogram openings 15 and driving components, the first rotating rods 12 are installed on the side of the opening 11 by a rotating connection; in this way, the stirring component is ensured to rotate stably inside the constant temperature tank 8, and the stirring uniformity and anti-crystallization effect are improved.

[0044] When the first stirring blade 13 is fixedly connected to the circumferential surface of the first rotating rod 12 and rotates with it, the stirring blade continuously disturbs the ammonia water, breaking the static environment for crystal formation; thus, it effectively prevents the ammonia water from crystallizing and clogging due to standing during low-temperature transportation, ensuring smooth transportation.

[0045] When the first gear 14 is fixedly connected to the upper end of the first rotating rod 12 and meshes with the second gear 17 in the drive assembly, the drive assembly can transmit power to the first rotating rod; in this way, the two sets of stirring components can operate synchronously, improving stirring efficiency and uniformity.

[0046] When the parallelogram opening 15 is located at the side end of the first stirring blade 13, this structure can enhance the flow disturbance of ammonia water during stirring and improve stirring efficiency; in this way, more thorough mixing and temperature homogenization can be achieved in a limited space, further reducing the risk of crystallization.

[0047] When the drive component is located at the upper end of the opening 11 and drives the second rotating rod 16 and the stirring scraper 18 through the motor 20, the entire stirring system can achieve automated control and continuous operation; thus, the intelligence level and ease of operation of the device are improved.

[0048] In this way, when the stirring component works in conjunction with the first rotating rod 12, the first stirring blade 13 and the driving component, it achieves efficient stirring and crystallization suppression of ammonia water in the constant temperature tank 8; thus, when the ambient temperature changes or the conveying distance is long, the fluidity of ammonia water and the stable operation of the conveying system can still be maintained.

[0049] Please refer to the details. Figure 1-4 The drive assembly includes a second rotating rod 16, a second gear 17, a stirring scraper 18, a fixed base 19, and a motor 20. The second rotating rod 16 is rotatably connected to the side end of the opening 11. The second gear 17 is fixedly connected to the upper end of the second rotating rod 16 and meshes with the first gear 14. The stirring scraper 18 is fixedly connected to the circumferential surface of the second rotating rod 16. The fixed base 19 is fixedly connected to the upper end of the opening 11. The motor 20 is fixedly connected to the side end of the fixed base 19, and the output end of the motor 20 is connected to the second rotating rod 16.

[0050] In this embodiment: when the drive assembly includes a second rotating rod 16, a second gear 17, a stirring scraper 18, a fixed base 19, and a motor 20, and the second rotating rod 16 is rotatably connected to the side end of the opening 11, the power structure of the drive assembly can be stably installed; thus, the operational stability and transmission reliability of the entire stirring system are ensured.

[0051] When the second gear 17 is fixedly connected to the upper end of the second rotating rod 16 and meshes with the first gear 14, the power is transmitted to the first rotating rod 12 through gear transmission; in this way, the synchronous operation of multiple sets of stirring components is realized, improving stirring efficiency and uniformity.

[0052] When the stirring scraper 18 is fixedly connected to the circumferential surface of the second rotating rod 16 and rotates with it, the scraper periodically cleans the inner wall of the constant temperature tank 8; in this way, ammonia water crystals adhere to the inner wall of the tank, affecting the heat exchange efficiency and the stability of the transport.

[0053] When the fixed base 19 is fixedly connected to the upper end of the opening 11 and serves as the mounting base for the motor 20, the output end of the motor is connected to the second rotating rod 16; in this way, a stable power input is provided for the entire drive assembly, realizing the automated operation of the stirring system.

[0054] When the motor 20 starts and drives the second rotating rod 16 to rotate, the second gear 17 drives the first gear 14 to rotate, thereby driving the first rotating rod 12 and the stirring blade to run; in this way, a complete power transmission chain is formed, realizing the coordinated operation of stirring and scraping functions.

[0055] In this way, the drive assembly achieves efficient driving of the stirring component and scraper through the cooperation of the motor 20, the second rotating rod 16 and the gear transmission structure; thus, when ammonia water encounters temperature fluctuations or runs for a long time during low-temperature transportation, the inner wall of the tank can still be kept clean and the liquid flow can be smooth, effectively preventing the occurrence of crystallization blockage problems.

[0056] Please refer to the details. Figure 1-4 A first connecting pipe 21 connects the first conveying tank 2 and the constant temperature tank 8, and a second connecting pipe 22 connects the constant temperature tank 8 and the second conveying tank 3.

[0057] In this embodiment: when a first connecting pipe 21 is connected between the first conveying tank 2 and the constant temperature tank 8, ammonia water can be stably conveyed from the first conveying tank to the inside of the constant temperature tank through the connecting pipe; in this way, a continuous material flow basis is provided for the subsequent constant temperature and stirring treatment, ensuring that the conveying process is uninterrupted and does not get blocked.

[0058] When the constant temperature tank 8 is connected to the second connecting pipe 22, the ammonia water after heating and stirring is transported to the second conveying tank through the connecting pipe; in this way, the entire low temperature anti-crystallization conveying process is completed, ensuring that the ammonia water still has good fluidity at the end of the conveying process.

[0059] When the first connecting pipe 21 and the second connecting pipe 22 are connected to different functional tanks respectively, their internal channels form a communication structure with the constant temperature tank; in this way, the entire conveying system has good connectivity and coordination, and improves the stability of the device in continuous operation.

[0060] When the connecting pipelines are made of corrosion-resistant materials and a sealing structure is installed at the connection, ammonia leakage or the entry of external impurities can be effectively prevented. This improves the sealing performance and operational safety of the entire device and extends the service life of the equipment.

[0061] In this way, when the first connecting pipe 21 and the second connecting pipe 22 together form the flow path between the constant temperature tank 8 and the conveying tank, the entire process of preventing blockage of ammonia water from initial conveying, constant temperature stirring to final output is realized. In this way, when the ambient temperature is low or the conveying distance is long, the continuity and safety of ammonia water conveying can still be ensured, and the crystallization blockage problem can be effectively prevented.

[0062] Please refer to the details. Figure 1-4 The first conveying tank 2 is fixedly connected to the side end of the feed pipe 4, and the feed pipe 4 is connected to the external equipment through a flange.

[0063] In this embodiment: when the feed pipe 4 is fixedly connected to the side end of the first conveying tank 2, the ammonia raw material can stably enter the interior of the first conveying tank through the feed pipe; in this way, a reliable feed channel is provided for the entire conveying process, ensuring continuous feeding of the system.

[0064] When the feed pipe 4 is connected to external equipment via a flange, the connection structure has good sealing and disassembly capabilities; this facilitates quick installation and disassembly between equipment, improves maintenance and cleaning efficiency, and prevents ammonia leakage, ensuring a safe operating environment.

[0065] When corrosion-resistant gaskets are used at flange connections, the sealing performance at the interface can be effectively enhanced, preventing leakage caused by vibration or temperature changes. This improves the stability and safety of the entire device under complex operating conditions.

[0066] Please refer to the details. Figure 1-4 The second conveying tank 3 is fixedly connected to the side end of the discharge pipe 5, which is connected to the external equipment through a flange.

[0067] In this embodiment: when the discharge pipe 5 is fixedly connected to the side end of the second conveying tank 3, the ammonia water after constant temperature stirring treatment can be stably output to the downstream equipment through the discharge pipe; in this way, a reliable discharge channel is provided for the entire anti-blockage conveying process, ensuring the continuous and efficient operation of the system.

[0068] When the discharge pipe 5 is connected to external equipment via a flange, this connection method has good sealing and disassembly capabilities; this facilitates quick installation and separation between equipment, improves operating efficiency, and prevents ammonia leakage at the end of the conveying process, ensuring on-site operational safety.

[0069] When the flange connection structure uses corrosion-resistant materials and sealing gaskets, it can effectively resist the corrosive effect of ammonia water, enhance the sealing performance and service life of the interface; thus, it improves the stability and reliability of the entire device in long-term operation or complex environments.

[0070] Please refer to the details. Figure 1-4 The air inlet 7 and the opening 11 are connected vertically and located on the circumferential surface of the constant temperature tank 8.

[0071] In this embodiment: when the air inlet 7 and the opening 11 are vertically connected and the air inlet is located on the circumferential surface of the constant temperature tank 8, external cold air or hot air can be evenly introduced into the interlayer space between the constant temperature tank and the box through the air inlet; in this way, a stable airflow channel is provided for the temperature control inside the constant temperature tank, ensuring the uniformity and stability of the ammonia water temperature inside the tank.

[0072] When the air inlet 7 is connected to the opening 11, the airflow can form a good circulation path inside the box; this helps to improve the heat exchange efficiency, enhance the heater 9's ability to control the temperature of the constant temperature tank 8, and prevent ammonia crystallization caused by local temperature difference. The air inlet 7 is equipped with a fan as in the prior art to achieve air intake.

[0073] When multiple air inlets 7 are set on the circumferential surface of the constant temperature tank 8 and are switched and connected to different temperature-controlled air sources, the air inlet temperature can be adjusted according to the actual conveying requirements; in this way, the device has a stronger environmental adaptability and meets the low-temperature conveying anti-blocking requirements under different working conditions.

[0074] In this way, when the air inlet 7 and the opening 11 form a vertically connected structure and are set on the circumferential surface of the constant temperature tank 8, efficient control of the internal temperature of the constant temperature tank is achieved. In this way, when the device is in a low temperature environment or under long-term operation, it can still maintain the fluidity of ammonia water in the tank, effectively prevent crystallization blockage, and ensure the safety and stability of the transportation process.

[0075] The working principle of this utility model is as follows: Before use, the entire device is first installed on a flat and stable ground using the frame 1. The first conveying tank 2 and the second conveying tank 3 are fixed to the upper sides of the frame 1, respectively. The inlet pipe 4 and the outlet pipe 5 are connected to the external feeding and receiving equipment via flanges, ensuring a good seal and no leakage at the connection points. The housing 6 is installed above the frame 1, and its interior contains a constant temperature tank 8, a stirring component, and an opening 11. The top plate 10 and the air inlet 7 are assembled to form a complete constant temperature control and stirring space. Before starting the device, check whether the heater 9 is working properly, ensuring it is fixed to the circumferential surface of the constant temperature tank 8 and can uniformly heat the inside of the tank. The stirring component includes the first... The system consists of a rotating rod 12, a first stirring blade 13, a first gear 14, a parallelogram-shaped inlet 15, and a drive assembly. The drive assembly comprises a second rotating rod 16, a second gear 17, a stirring scraper 18, a fixed base 19, and a motor 20. All components are installed in place and reliably connected. At startup, ammonia water enters the first conveying tank 2 from external equipment through the feed pipe 4, and then flows into the constant temperature tank 8 through the first connecting pipe 21. At this time, the heater 9 starts to compensate for the temperature in the constant temperature tank, preventing the ammonia water from crystallizing due to low temperature. Simultaneously, the motor 20 starts, driving the second rotating rod 16 to rotate, causing the second gear 17 to rotate and mesh with the first gear 14, driving the first rotating rod 12 and the first stirring blade 13 to operate synchronously in the constant temperature tank. The ammonia water in tank 8 is continuously stirred. During the stirring process, the parallelogram-shaped opening 15 on the stirring blade 13 enhances liquid turbulence and improves stirring uniformity. The stirring scraper 18 is fixed on the second rotating rod 16 and rotates to periodically clean the inner wall of the constant temperature tank 8, preventing crystals from adhering and affecting heat exchange efficiency. The entire stirring system is controlled by a drive component, ensuring stable operation and good automation performance. At the same time, the external temperature control system sends cold or hot air into the tank 6 through the air inlet 7. The airflow passes through the opening 11, circulating through the space around the constant temperature tank 8, forming a circulating airflow field, further improving the temperature control effect of the constant temperature tank. The air source type can be switched according to the actual conveying environment to achieve dynamic temperature control of the constant temperature tank. The system adjusts the temperature to ensure the ammonia solution remains within a suitable transport temperature range. After temperature control and stirring, the ammonia solution is transported to the second transport tank 3 via the second connecting pipe 22, and then output to downstream application equipment via the discharge pipe 5. The discharge pipe 5 also uses a flange connection to ensure a secure and well-sealed connection, preventing leakage at the end of the transport process. Throughout the entire operation, the device effectively prevents crystallization and blockage of ammonia solution during low-temperature transport through multiple measures such as temperature control, stirring to prevent crystallization, airflow circulation regulation, and sealed transport, ensuring the continuity, stability, and safety of the transport process. The device has a reasonable structure, is easy to operate, and is suitable for ammonia solution transport needs in various complex environments, showing promising prospects for industrial applications.
