Description

TECHNICAL FIELD

[0001] The utility model relates to the field of pipeline anti -blocking, especially a pipeline anti -blocking device based on ammonium fluoride production. BACKGROUND

[0002] In the production of ammonium fluoride, factors such as solution concentration, pH value, stirring intensity and purity can significantly affect the crystallization temperature.

[0003] Specifically, the higher the solution concentration, the more the number of ammonium fluoride molecules in the solution, the more opportunities for collision and combination, thereby increasing the crystallization rate and possibly leading to an increase in crystallization temperature. Too high or too low pH value can destroy the stability of ammonium fluoride molecules, thereby affecting the crystallization temperature and quality. Proper stirring can improve the heat transfer efficiency in the solution and promote the uniform distribution of ammonium fluoride molecules, thereby affecting the crystallization rate and temperature, but too strong or too weak stirring can adversely affect the crystallization process. High-purity ammonium fluoride is more likely to form a regular crystal structure, so its crystallization temperature may be relatively low, while the presence of impurities can interfere with the crystallization process, leading to an increase in crystallization temperature or a decrease in crystallization quality.

[0004] Taking these factors into account, the crystallization temperature of ammonium fluoride is usually between 95℃ and 100℃. However, in actual production, in order to ensure the quality of ammonium fluoride crystals, fine control of various influencing factors is required according to specific circumstances.

[0005] Traditional pipeline insulation measures often cannot well solve the problems of crystallization and increased viscosity that occur during the production of ammonium fluoride, affecting the continuity of production and product quality. Simply relying on pipeline insulation, the temperature cannot be maintained above 40℃, and ammonium fluoride solution below 40℃ may crystallize on the pipe wall, and long-term low temperature can cause the pipe diameter to decrease until the pipeline is completely blocked. Therefore, an efficient heating method is needed to solve this problem and ensure the stability of ammonium fluoride production and product quality. SUMMARY

[0039] Please refer to Figures 1 to 5 The embodiment provides a pipeline anti-blocking device based on ammonium fluoride production, which comprises a hot water bin 10, a heat tracing pipe 20, a first water inlet pipeline 40 and a first water outlet pipeline 50. The hot water bin 10 is internally provided with a hot water cavity 11 for containing hot water. The heat tracing pipe 20 is wrapped on an ammonium fluoride solution conveying pipe 30, and is used for heating the ammonium fluoride solution conveying pipe 30. The first water inlet pipeline 40 is connected with the hot water bin 10 at the water inlet end, and is connected with the heat tracing pipe 20 at the water outlet end. The first water inlet pipeline 40 is used for conveying hot water to the heat tracing pipe 20. The first water outlet pipeline 50 is connected with the hot water bin 10 at the water outlet end, and is connected with the heat tracing pipe 20 at the water inlet end. The first water outlet pipeline 50 is used for conveying the water in the heat tracing pipe 20 to the hot water bin 10.

[0040] In the embodiment, the hot water bin 10 is internally provided with a hot water cavity 11 for containing hot water, so that the stable supply of hot water is ensured, and the continuous heating requirement of the subsequent heat tracing pipe 20 is met. The volume and heating power of the hot water bin 10 can be reasonably matched according to the actual production scale, so that the hot water reserve amount can meet the continuous requirement in the production process.

[0041] The heat tracing pipe 20 is wrapped on the ammonium fluoride solution conveying pipe 30. This direct heat tracing mode can effectively improve the heat transfer efficiency, so that the temperature inside the solution pipeline can be kept within an appropriate range, and the crystallization and blocking of ammonium fluoride caused by temperature drop are avoided. The heat tracing pipe 20 can adopt various heating modes such as electric heat tracing or steam heat tracing, and the selection can be made according to the site conditions and energy supply conditions.

[0042] The water inlet end of the first water inlet pipeline 40 is connected with the hot water bin 10, and the water outlet end is connected with the heat tracing pipe 20, which is used for supplying hot water to the heat tracing pipe 20. The water inlet end of the first water outlet pipeline 50 is connected with the heat tracing pipe 20, and the water outlet end is connected with the hot water bin 10, which is used for returning the heated hot water to the hot water bin 10, so as to form a closed loop circulation system. This pipeline design not only ensures the continuous supply of hot water, but also maximizes the use of heat, thereby improving the overall energy utilization efficiency.

[0043] In summary, the scheme provided by the embodiment can effectively solve the problem of crystallization and blockage of ammonium fluoride solution during transportation. Through the integrated application of hot water tank 10 and heat tracing pipe 20, it is ensured that the solution pipeline is always at a suitable heating temperature, preventing the crystallization and blockage of ammonium fluoride inside the pipeline. Not only does it improve the stability of production, but it also avoids equipment failure and maintenance costs caused by pipeline blockage. The closed-loop circulation design of the inlet and outlet water pipelines realizes efficient use of hot water and recycling of heat, not only reducing the consumption of hot water, but also reducing energy consumption, greatly improving the overall energy utilization efficiency of the device. At the same time, the recycling of hot water also avoids the loss of a large amount of heat, further improving the environmental performance of the device.

[0044] Please refer to Figures 1 to 5 In some embodiments, a pipeline anti-blocking device based on ammonium fluoride production further comprises: a second inlet water pipeline 60 and a second outlet water pipeline 70, the second inlet water pipeline 60 is connected with the hot water tank 10, and the second inlet water pipeline 60 is used to input hot water into the hot water tank 10; the second outlet water pipeline 70 is connected with the hot water tank 10, and the second outlet water pipeline 70 is used to discharge water in the hot water tank 10.

[0045] In this embodiment, one end of the second inlet water pipeline 60 is connected with the hot water tank 10, which is used to input hot water into the hot water tank 10, so as to ensure that the hot water reserve in the hot water tank 10 can continuously meet the demand in the production process. The second outlet water pipeline 70 is responsible for discharging water in the hot water tank 10, which can prevent the water level in the hot water tank 10 from being too high and avoid the safety hazard caused by water overflow; on the other hand, regular replacement of water in the hot water tank 10 can ensure the cleanliness and temperature stability of the hot water. Further, the second outlet water pipeline 70 can recycle the discharged hot water, such as for workshop heating or other production purposes, which not only reduces the consumption of water resources, but also avoids the loss of a large amount of heat, further improving the energy utilization efficiency.

[0046] Through the setting of the second inlet water pipeline 60 and the second outlet water pipeline 70, the hot water reserve in the hot water tank 10 can be continuously supplemented, avoiding the interruption of production caused by the depletion of hot water; at the same time, regular water level adjustment also ensures the cleanliness of the hot water, avoiding the decline of heat tracing effect caused by poor water quality.

[0047] Please refer to Figures 1 to 5 In some embodiments, the flow direction of hot water in the heat tracing pipe 20 is opposite to the flow direction of ammonium fluoride solution in the ammonium fluoride solution conveying pipe 30; and along the hot water flow direction, the connection between the first inlet water pipeline 40 and the heat tracing pipe 20 is located upstream of the connection between the first outlet water pipeline 50 and the heat tracing pipe 20.

[0048] In this embodiment, when the ammonium fluoride solution flows downward along the delivery pipe, the hot water in the heat tracing pipe 20 flows in the opposite direction, forming an effective convection of heat. This counter-flow configuration allows the hot water to be in contact with the ammonium fluoride solution for a longer period of time in the heat tracing pipe 20, enhancing the heat exchange effect and ensuring that the ammonium fluoride solution remains within the appropriate temperature range throughout the delivery process, reducing the risk of crystallization and blockage, thereby improving the continuity and stability of production. In addition, the design of the heat tracing pipe 20 also takes into account the effects of fluid dynamics, by optimizing the diameter and layout of the heat tracing pipe 20, reducing the resistance of fluid flow and improving the flow rate and heat exchange efficiency of the hot water. The connection between the first water inlet pipe 40 and the heat tracing pipe 20 is located upstream of the connection between the first water outlet pipe 50 and the heat tracing pipe 20, which can ensure that the hot water can be fully heated before entering the heat tracing pipe 20, thereby improving the timeliness and effectiveness of the heat tracing.

[0049] Please refer to Figures 1 to 5 In some embodiments, a pipe anti-blocking device based on ammonium fluoride production also includes a magnetic valve 41 and a first water inlet regulating valve 42, both of which are placed on the first water inlet pipe 40; and along the water flow direction, the magnetic valve 41 is placed upstream of the first water inlet regulating valve 42.

[0050] In this embodiment, the magnetic valve 41 is located upstream in the water flow direction and is responsible for controlling the flow state of the hot water. The design of the magnetic valve 41 allows it to automatically open or close when receiving an electrical signal, thereby achieving precise control of the hot water flowing into the heat tracing pipe 20, ensuring that hot water can flow into the heat tracing pipe 20 immediately and stably when hot water is needed to heat the ammonium fluoride solution, enhancing the response speed and flexibility of the system.

[0051] The first water inlet regulating valve 42 is used to adjust the flow of hot water into the heat tracing pipe 20 to meet the needs of different production processes. The first water inlet regulating valve 42 can be equipped with a flow meter and a sensor to monitor and adjust the flow of hot water into the heat tracing pipe 20 in real time, ensuring that the ammonium fluoride solution always remains within the optimal temperature range, further reducing the risk of crystallization and blockage.

[0052] Further, a second water inlet regulating valve is also included, which is placed on the second water inlet pipe 60 to adjust the amount of water entering the hot water tank 10. In actual operation, the second water inlet regulating valve can be linked with an automatic control system, automatically adjusting the amount of water entering the hot water tank 10 according to the feedback of the water level sensor in the hot water tank 10, ensuring that the water level in the hot water tank 10 always remains within a reasonable range.

[0053] Through the coordination of magnetic valve 41 and first water inlet regulating valve 42, the system can flexibly adjust the flow and temperature of hot water according to real-time demand, providing reliable guarantee for the stable delivery of ammonium fluoride solution and reducing the risk of crystallization and blockage caused by temperature fluctuations. At the same time, the application of regulating valve can effectively manage water resources, ensure that the water quantity in hot water warehouse 10 is within a reasonable range, thereby improving the continuity and stability of production.

[0054] Please refer to Figures 1 to 5 In some embodiments, the pipe anti-blocking device based on ammonium fluoride production further comprises a heat tracing pipe temperature measuring rod 21, the detection end of the heat tracing pipe temperature measuring rod 21 is placed inside the heat tracing pipe 20, and the heat tracing pipe temperature measuring rod 21 is used to measure the temperature inside the heat tracing pipe 20.

[0055] In this embodiment, the detection end of the heat tracing pipe temperature measuring rod 21 is placed inside the heat tracing pipe 20, ensuring that the temperature measurement can directly reflect the actual temperature condition of the ammonium fluoride solution inside the heat tracing pipe 20. The temperature measuring rod can use high-precision temperature sensors such as thermocouples or thermal resistors to quickly and accurately collect temperature data inside the heat tracing pipe 20. Through real-time temperature monitoring of the heat tracing pipe temperature measuring rod 21, the temperature stability of the ammonium fluoride solution during the delivery process is ensured, thereby effectively preventing crystallization and pipe blockage, and improving the reliability of the entire production process.

[0056] Further, the heat tracing pipe temperature measuring rod 21 is connected to the control system through a connected cable, and transmits real-time temperature data to the central control unit. The control unit can analyze the received temperature data to determine whether the current temperature inside the heat tracing pipe 20 meets the requirements of the production process. When the temperature is lower than the set safety threshold, the control system can automatically adjust the hot water flow in the heat tracing pipe 20, or start the standby heating device, to ensure that the ammonium fluoride solution always remains in the appropriate temperature range, optimize the flow and temperature of hot water, and improve the utilization efficiency of resources. At the same time, the setting of the heat tracing pipe temperature measuring rod 21 is also conducive to system fault diagnosis, timely discovery and solution of abnormal conditions inside the heat tracing pipe 20, and ensures the smooth progress of the entire production process.

[0057] Please refer to Figures 1 to 5 In some embodiments, the pipe anti-blocking device based on ammonium fluoride production further comprises a first water outlet regulating valve 51, which is placed on the first water outlet pipe 50.

[0058] In this embodiment, the first water outlet regulating valve 51 is located on the first water outlet pipeline 50 to regulate the amount of hot water flowing out of the heat tracing pipe 20. By real-time control of the regulating valve, it can ensure that the amount of hot water flowing out of the heat tracing pipe 20 can meet the actual heating needs of the ammonium fluoride solution, avoiding the situation of excess or insufficient heat, thereby ensuring the optimal temperature of the solution during the entire delivery process. Further, the first water outlet regulating valve 51 can automatically adjust the discharge flow of hot water according to the temperature data fed back by the heat tracing pipe temperature measuring rod 21, ensuring the optimal state of heat transfer.

[0059] Further, it also includes a second water outlet regulating valve, which is placed on the second water outlet pipeline 70 to regulate the amount of water flowing out of the hot water tank 10, thereby ensuring that the water level inside the hot water tank 10 can always be maintained within a reasonable range, avoiding problems caused by excessively high or low water levels. When the water level in the hot water tank 10 is too high, the second water outlet regulating valve will automatically open to discharge excess hot water to maintain the stability of the water level. Conversely, when the water level is low, the second water outlet regulating valve will be appropriately closed to reduce the discharge amount of hot water, ensuring sufficient hot water reserves in the hot water tank 10. This dynamic adjustment mechanism can effectively avoid the situation of insufficient or excessive hot water supply, improving the operational stability of the entire system.

[0060] In addition, the first water outlet regulating valve 51 and the second water outlet regulating valve can also be linked with the control system to realize intelligent management of the entire hot water circulation system. The control system can automatically adjust the opening of the first water outlet regulating valve 51 and the second water outlet regulating valve according to real-time monitoring of temperature and water level data, ensuring that the flow and temperature of hot water are always in the best state, providing strong protection for the stable delivery of ammonium fluoride solution. This intelligent management method not only improves production efficiency, but also reduces the need for manual intervention, reducing the workload of operating personnel.

[0061] Please refer to Figures 1 to 5 In some embodiments, a pipe anti-blocking device based on ammonium fluoride production also includes a hot water tank temperature measuring rod 12 and a radar wave liquid level meter 13.

[0062] The detection end of the hot water tank temperature measuring rod 12 is placed in the hot water cavity 11 to measure the temperature of the hot water in the hot water cavity 11, and the radar wave liquid level meter 13 is placed on the top of the hot water tank 10, and the detection end of the radar wave liquid level meter 13 is placed in the hot water cavity 11 to measure the water level of the hot water in the hot water cavity 11.

[0063] In this embodiment, the detection end of the hot water tank temperature probe 12 is placed inside the hot water cavity 11, which can directly monitor the actual temperature of the hot water in the hot water cavity 11. This direct measurement method can accurately reflect the temperature change of the hot water in the hot water tank 10, providing real-time and reliable temperature data for the control system. The hot water tank temperature probe 12 can use high-precision temperature sensors such as thermocouples or thermistors to quickly and accurately collect hot water temperature information. By collecting temperature data, the control system can dynamically adjust the supply of hot water according to real-time temperature, ensuring that the hot water tank 10 always maintains a suitable temperature range, providing a stable hot water source for the subsequent heating needs of the heat tracing pipe 20.

[0064] The radar wave liquid level meter 13 is placed on the top of the hot water tank 10, with its detection end extending into the hot water cavity 11, allowing it to monitor the liquid level changes of the hot water in the hot water cavity 11 in real time. Specifically, the radar wave liquid level meter 13 measures the height of the hot water surface by transmitting and receiving microwave signals, thereby calculating the actual water level inside the hot water cavity 11. These water level information can be fed back to the control system together with the temperature data, allowing the system to fully understand the operating status of the hot water tank 10 and automatically adjust the water inflow and outflow according to real-time needs, ensuring that the water level inside the hot water tank 10 remains within the optimal range.

[0065] In summary, through the integrated application of the hot water tank temperature probe 12 and the radar wave liquid level meter 13, this embodiment achieves comprehensive monitoring of the temperature and water level inside the hot water tank 10, providing reliable data support for the intelligent management of the entire hot water circulation system.

[0066] Please refer to Figures 1 to 5 In some embodiments, a pipeline anti-blocking device based on ammonium fluoride production also includes an exhaust port 14, a water replenishment pipeline 15, and a water replenishment regulating valve 16; the exhaust port 14 is placed on the top of the hot water tank 10, and the exhaust port 14 is in communication with the hot water cavity 11; the water replenishment regulating valve 16 is placed on the water replenishment pipeline 15, and the water replenishment pipeline 15 is connected to the hot water tank 10.

[0067] In this embodiment, the exhaust port 14 is placed on the top of the hot water tank 10 and is in communication with the hot water cavity 11, which is used to exhaust the gas that may accumulate in the hot water tank 10. Through the design of the exhaust port 14, the gas in the hot water tank 10 can be quickly exhausted, avoiding the impact of gas on the circulation and heating efficiency of the hot water, and ensuring that the hot water can flow smoothly into the heat tracing pipe 20. This design not only helps to improve the heating efficiency of the hot water, but also prevents pressure abnormalities caused by gas accumulation, thereby improving the safety of the system.

[0068] The water supplement pipeline 15 is connected with the hot water bin 10, and the water supplement adjusting valve 16 is arranged on the water supplement pipeline 15, which is used for adjusting the water amount entering the hot water bin 10, so that the hot water bin 10 can dynamically supplement water according to actual needs to maintain a proper water level. The water supplement adjusting valve 16 can be adjusted by an automatic control system or manual operation to adjust the water supplement flow, so that the hot water bin 10 can always maintain a suitable water level, avoiding the influence of hot water supply due to too low water level or overflow or waste due to too high water level. The water supplement system can be linked with the hot water bin temperature measuring rod 12 and the radar wave liquid level meter 13 to monitor the water level and temperature data in real time, so as to realize efficient water resource management.

[0069] Further, the following examples can be developed in combination with the above-mentioned solutions:

[0070] The design plan determines the volume of the hot water bin 10 according to the production process requirements and the total length of the heat tracing pipe 20, 10 m 3 The size of the double-layer pipeline is DN32 for the inner layer and DN50 for the outer layer. The circulation path of the hot water heat tracing system is planned, including the location of the hot water supply source, the flow direction of the hot water, and the path of the return water, etc.

[0071] The pipeline structure is designed to adopt a double-layer structure, with the inner layer being the ammonium fluoride solution delivery pipe 30 and the outer layer being the heat tracing pipe 20. The hot water flows in the heat tracing pipe 20, which can quickly transfer heat to the ammonium fluoride solution delivery pipe 30. The connection parts of the pipeline adopt heat welding, and the pipeline outside is wrapped with thermal insulation materials to prevent heat loss and ammonium fluoride leakage. The hot water bin 10 uses a magnetic valve 41 to continuously deliver hot water to the heat tracing pipe 20, ensuring that the temperature of the pipeline is consistent with the temperature of the hot water bin 10.

[0072] The pipeline installation is carried out according to the designed direction. Each section of the pipeline is 3 meters long to prevent the pipeline from sagging due to being too long. The inner pipeline (i.e., the ammonium fluoride solution delivery pipe 30) is prohibited from using spliced pipelines, and the outer pipeline is installed with a heat tracing pipe temperature measuring rod 21 to monitor the temperature inside the pipeline. An adjusting valve is installed on the first water inlet pipeline 40 to adjust the flow of hot water, thereby controlling the heat tracing temperature; a thermometer and a pressure gauge are installed on the first water outlet pipeline 50 to monitor the temperature and pressure of the hot water.

[0073] The heat tracing pipe 20 is laid along the ammonium fluoride solution delivery pipe 30. The heat tracing pipe 20 is made of PP material, which is corrosion-resistant, has good heat conductivity, and is low in price. The device is provided with an intelligent temperature control system, which includes a heat tracing pipe temperature measuring rod 21 installed inside the pipeline, which can monitor the temperature of the heat tracing pipe 20 in real time. The sensor transmits the temperature signal to the controller, which adjusts the heat tracing temperature according to the preset temperature value (for example, the temperature range for maintaining the best fluidity of ammonium fluoride solution, such as 35-40℃).

[0074] When the system is connected and debugged, the first water inlet pipeline 40 is connected with the hot water bin 10, the water outlet end of the first water inlet pipeline 40 is connected with the heat tracing pipe 20, the water outlet end of the first water outlet pipeline 50 is connected with the hot water bin 10, and the water inlet end of the first water outlet pipeline 50 is connected with the heat tracing pipe 20. When connected, ensure the sealing property to prevent hot water leakage. Start the hot water supply system, and gradually adjust the flow and temperature of the hot water. Initially, the temperature of the hot water can be set to 40-50 DEG C, and adjusted according to the conveying state of the ammonium fluoride. During the debugging process, check whether the entire device has a leakage phenomenon, including the inner layer ammonium fluoride solution conveying pipe 30 and the outer layer heat tracing pipe 20. The pressure test method can be used to test the ammonium fluoride solution conveying pipe 30, the pressure is about 1.5 times of the working pressure, and lasts for 30 minutes, and whether the pressure decreases is observed; the outer layer heat tracing pipe 20 is checked to see whether there is water leakage at each connection position.

[0075] Before starting the ammonium fluoride production, the device is used to preheat the pipeline to a suitable temperature, for example, 35 DEG C. During the production process, the intelligent temperature control system continuously monitors the pipeline temperature, and dynamically adjusts the second water inlet regulating valve of the hot water bin 10 according to the temperature fluctuation. If the temperature is lower than 35 DEG C, the opening degree of the second water inlet regulating valve is increased; if the temperature is higher than 40 DEG C, the opening degree of the second water inlet regulating valve is reduced.
