[0026] like Figure 1 and Figure 2 As shown in the embodiments of this utility model, a distillation endpoint determination device and a sponge titanium distillation production system are provided. The distillation endpoint determination device is applied to the sponge titanium distillation production system to determine when the sponge titanium distillation production system has completed distillation and reached the distillation endpoint.
[0027] like Figure 1 and Figure 2As shown in the first aspect of this utility model, a distillation endpoint determination device 100 is provided, comprising: an observation window 110; a sponge titanium distillation production system 200 including a distillation container 210, a condenser container 220, and a connecting pipe 230 connecting the distillation container 210 and the condenser container 220; paired observation windows 110 arranged in a direction perpendicular to the flow direction of the connecting pipe 230 and respectively disposed on the pipe walls on opposite sides of the connecting pipe 230; an infrared imager 120 disposed on one side of the connecting pipe 230, opposite to the observation window 110, configured to acquire thermal images through the observation window 110; a cold plate 130 disposed on the other side of the connecting pipe 230, opposite to the observation window 110; and a processing module connected to the infrared imager 120, configured to determine the distillation endpoint based on the temperature distribution characteristics of the thermal image.
[0028] like Figure 1 As shown, the sponge titanium distillation production system 200 includes a distillation container 210, a condenser container 220, and a connecting pipe 230 connecting the distillation container 210 and the condenser container 220. During the distillation process, high-temperature volatile gas flows from the distillation container 210 into the condenser container 220 through the connecting pipe 230.
[0029] like Figure 1 As shown, the distillation endpoint determination device 100 provided in this embodiment of the present invention includes an observation window 110, an infrared imager 120, a cold plate 130, and a processing module. The external thermal imager is a precision instrument that uses the principle of infrared radiation to receive the infrared radiation energy emitted by the surface of an object and convert it into a visible thermal image, thereby realizing the visual measurement of the temperature distribution characteristics of the surface of the object.
[0030] In this embodiment, the observation windows 110 are arranged in pairs, i.e., there are two observation windows 110. The two observation windows 110 are arranged in a direction perpendicular to the flow direction of the connecting pipe 230, and are respectively located on opposite sides of the pipe wall of the connecting pipe 230, meaning the line connecting the two observation windows 110 is perpendicular to the flow direction of the connecting pipe 230. The infrared imager 120 and the cold plate 130 are respectively located on opposite sides of the connecting pipe 230, and are respectively positioned opposite to the observation window 110 on their respective sides. Thus, the infrared imager 120 can acquire thermal images of the observed object at a relative position within the connecting pipe 230 through the observation windows 110, thereby achieving the measurement of the temperature distribution characteristics of the fluid or object at the position opposite to the observation window 110 within the connecting pipe 230. The cold plate 130 has a low temperature, typically a low-temperature cold plate, with a temperature range of room temperature or slightly below room temperature. The cold plate 130 provides a stable low-temperature reference background for the infrared imager 120. By connecting the processing module to the infrared imager 120 signal, the processing module can determine whether the distillation has reached its endpoint based on the temperature distribution characteristics of the thermal image.
[0031] Specifically, before distillation, the infrared imager 120 can acquire a thermal image of the connecting pipe 230 at a relative position through the observation window 110. Since distillation is not yet underway, and the cold plate 130 is opposite the observation window 110, the acquired thermal image is approximately that of the cold plate 130, and this is used as a reference. During distillation, high-temperature volatile gases flow into the condenser container 220 through the connecting pipe 230. As distillation progresses from the initial stage to completion, the high-temperature volatile gases gradually decrease until they disappear. By acquiring a thermal image of the connecting pipe 230 at a relative position in real time through the observation window 110 using the infrared imager 120, the processing module compares the temperature distribution characteristics of the thermal image acquired in real time during distillation with the temperature distribution characteristics of the thermal image of the low-temperature reference backplate acquired before distillation to determine whether the distillation has reached its endpoint.
[0032] Therefore, this embodiment transforms the determination of the distillation endpoint from subjective experience into objective data, ensuring accuracy and reliability. It achieves automatic and real-time determination of the distillation endpoint in the sponge titanium distillation production system 200. Compared to related technologies that rely on manual determination of the distillation endpoint, this method is more objective and can determine the endpoint in real time, improving the accuracy, timeliness, and objectivity of endpoint determination. This is beneficial for improving product quality, increasing distillation efficiency, reducing energy consumption, and reducing the labor intensity of operators, thus enhancing the automation level of sponge titanium production. Furthermore, the distillation endpoint determination device 100 provided in this embodiment has a simple structure, is easy to modify, and can be directly installed on the existing sponge titanium distillation production system 200 at a low cost, making it suitable for widespread application.
[0033] like Figure 1 As shown, in some possible embodiments provided by this utility model, the distillation endpoint determination device 100 further includes: a bracket 140, an infrared imager 120 connected to the bracket 140, and a cold plate 130 connected to the bracket 140.
[0034] In this embodiment, both the infrared imager 120 and the cold plate 130 are connected to the bracket 140. The bracket 140 provides stable support for the infrared imager 120 and the cold plate 130. Through the bracket 140, the infrared imager 120 and the cold plate 130 can be placed in appropriate positions, ensuring that the positions of the infrared imager 120 and the adjacent observation window 110 are reasonable, and that the positions of the low-temperature backplate and the adjacent observation window 110 are also reasonable. This ensures that the distillation endpoint determination device 100 can reliably and accurately determine the distillation endpoint. Furthermore, using a single bracket 140 to support and fix both the infrared imager 120 and the cold plate 130 simplifies the structure of the distillation endpoint determination device 100 and reduces its manufacturing cost.
[0035] Specifically, the support 140 can be one of a gantry-type support, a cantilever support, or a clamp-type support. The bottom of the support 140 can be fixed to the ground or the platform of the sponge titanium distillation production system 200 by anchor bolts to ensure the stability of the entire distillation endpoint determination device 100. It is understood that the support 140 can also be of other types, and can be adjusted according to the actual situation of the sponge titanium distillation production system 200, all of which fall within the protection scope of this utility model.
[0036] like Figure 1 As shown, in some possible embodiments provided by this utility model, the bracket 140 includes a crossbeam and an adjustable mounting base disposed on the crossbeam. The infrared imager 120 is connected to the adjustable mounting base. Thus, the infrared imager 120 can be fixed on the bracket 140 through the adjustable mounting base. Furthermore, the relative position of the infrared imager 120 and the crossbeam can be adjusted through the adjustable mounting base, so that the infrared imager 120 and the observation window 110 are in a suitable position and orientation. This allows the infrared imager 120 to reliably, accurately, and comprehensively acquire thermal images of the position relative to the observation window 110 within the connecting pipe 230, thereby improving the accuracy of the distillation endpoint determination.
[0037] The adjustable mounting base allows for adjustment of the relative position of the infrared imager 120 and the crossbeam in the horizontal and vertical directions, as well as the angle between the infrared imager 120 and the plane containing the observation window 110. This ensures that the position and orientation of the infrared imager 120 are adjustable in multiple directions, guaranteeing that the positions of the infrared imager 120 and the observation window 110 are reasonable and accurate.
[0038] The infrared imager 120 and the adjustable mounting base can be detachably connected, allowing for maintenance of the infrared imager 120 after disassembly, which helps save maintenance costs. Specifically, the infrared imager 120 and the adjustable mounting base can be detachably connected through at least one of the following structures: bolt structure, plug-in structure, snap-fit structure, tenon and mortise structure, and magnetic structure.
[0039] like Figure 1 and Figure 2 As shown, in some possible embodiments provided by this utility model, the projection of the lens centerline of the infrared imager 120 onto the observation window 110 coincides with the geometric center of the observation window 110.
[0040] The centerline of the lens of the infrared imager 120 can be understood as the optical lens axis of the infrared imager 120. The position and orientation of the infrared imager 120 are adjusted by the adjustable mounting base to ensure that the projection of the centerline of the lens of the infrared imager 120 on the observation window 110 coincides with the geometric center of the observation window 110. That is, the optical lens axis of the infrared imager 120 passes through the geometric center of the observation window 110 and is directly opposite the geometric center of the observation window 110. This allows the infrared imager 120 to reliably, accurately and comprehensively acquire thermal images of the position relative to the observation window 110 within the connecting pipe 230, thereby improving the accuracy of the distillation endpoint determination.
[0041] like Figure 1 As shown, in some possible embodiments provided by this utility model, the bracket 140 further includes a connecting arm, and the cold plate 130 is detachably connected to the connecting arm. Thus, the cold plate 130 can be fixed on the bracket 140 by means of the connecting arm, so that the position and orientation of the cold plate 130 and the observation window 110 are in a suitable position and orientation.
[0042] Understandably, in some examples, the connecting arm allows adjustment of the horizontal and vertical distances between the cold plate 130 and the observation window 110, as well as the angle between the planes of the cold plate 130 and the observation window 110. This enables the position and orientation of the cold plate 130 to be adjustable in multiple directions, ensuring that the positions of the cold plate 130 and the observation window 110 are reasonable and accurate. In some examples, the cold plate 130 and the connecting arm can be detachably connected for maintenance or replacement of the cold plate 130.
[0043] In some possible embodiments provided by this utility model, the observation window 110 is made of a high-temperature resistant and light-transmitting material, and the observation window 110 is sealed and embedded in the pipe wall of the connecting pipe 230.
[0044] In this embodiment, during the distillation process, a large amount of high-temperature volatile gas (approximately 800℃-900℃) flows from the distillation vessel 210 into the condensation vessel 220 via the connecting pipe 230. Therefore, making the observation window 110 a high-temperature resistant and light-transmitting material helps extend its service life and ensures that the infrared imager 120 can reliably and accurately acquire thermal images of the relative position of the observation window 110 through it, thus improving the accuracy of determining the distillation endpoint. Furthermore, sealing the observation window 110 within the wall of the connecting pipe 230 ensures vacuum and pressure sealing within the connecting pipe 230.
[0045] The observation window 110 can be circular, square, or other regular geometric shapes. The observation window 110 can be sealed within the detection hole on the wall of the connecting pipe 230 via flange connection or welding, ensuring vacuum and pressure sealing within the pipe. Specifically, the connecting pipe 230 may include a first section, a horizontal section, and a second section. The horizontal section connects the first and second sections. The first section is connected to the distillation vessel 210, and the second section is connected to the condensation vessel 220. The horizontal section extends horizontally, and two opposing detection holes are formed on its two vertical sidewalls. The two observation windows 110 are sealed within these detection holes. The infrared imager 120 is located above the horizontal section of the connecting pipe 230, and the cold plate 130 is located below the horizontal section of the connecting pipe 230.
[0046] It is understood that the shape and size of the observation window 110 can also be other, and can be adjusted according to the actual situation of the sponge titanium distillation production system 200, all of which fall within the protection scope of this utility model.
[0047] In some possible embodiments provided by this utility model, the observation window 110 is made of quartz glass. Specifically, the observation window 110 is made of high-temperature quartz glass. High-temperature quartz glass has extremely high heat resistance and thermal stability, as well as excellent optical transmittance. Therefore, it can meet the high-temperature working conditions of the connecting pipe 230, and ensure the imaging accuracy of the infrared imager 120, thereby improving the judgment accuracy of the distillation endpoint judgment device 100.
[0048] In some possible embodiments provided by this utility model, the cold plate 130 is a metal plate, and a high emissivity matte coating is provided on the side of the cold plate 130 facing the observation window 110.
[0049] In this embodiment, the cold plate 130 is a metal plate, meaning it is a metal cold plate with high strength, high reliability, and long service life. A high-emissivity matte coating is provided on the side of the metal plate facing the observation window 110. This high-emissivity matte coating significantly improves its heat dissipation capacity and also provides low gloss and anti-glare effects, which helps improve the detection accuracy of the infrared imager 120, thereby improving the judgment accuracy of the distillation endpoint determination device 100. Furthermore, it helps extend the service life of the distillation endpoint determination device 100.
[0050] like Figure 1 and Figure 2 As shown, in some possible embodiments provided by this utility model, the distillation endpoint determination device 100 further includes: a heat insulation component 150, the outer wall of the connecting pipe 230 is covered with the heat insulation component 150, and the heat insulation component 150 avoids the observation window 110.
[0051] In this embodiment, the area outside the connecting pipe 230, except for the observation window 110 area, is covered with a heat insulation component 150. This heat insulation component 150 covers the outer wall of the connecting pipe 230, providing good heat insulation for the connecting pipe 230. It can maintain the inner wall temperature of the connecting pipe 230 above the condensation point of the volatiles, thereby preventing substances such as magnesium and magnesium chloride from condensing when flowing through the observation window 110 area. This ensures that the observation window 110 is continuously transparent and that the temperature signal received by the infrared imager 120 accurately reflects the temperature change of the airflow inside the connecting pipe 230. It avoids contamination of the observation window 110 and interference with the temperature signal caused by the condensation of volatiles due to local low temperature in the connecting pipe 230. This is beneficial to improving the accuracy of the detection results of the infrared imager 120 and improving the judgment accuracy of the distillation endpoint judgment device 100.
[0052] The insulation component 150 can be made of high-temperature resistant ceramic fiber blanket, rock wool, etc. The insulation component 150 and the connecting pipe 230 are separate structures and can be installed on the outer wall of the connecting pipe 230 by means of adhesive, connection structure, or wrapping.
[0053] In some possible embodiments provided by this utility model, the outer wall of the connecting pipe 230 is provided with a thermal insulation coating. The thermal insulation coating can be applied to the outer wall of the connecting pipe 230 by spraying, smearing, or other methods. The material of the thermal insulation coating can be thermal insulation paint, thermal insulation adhesive, etc., such as thermal insulation paints such as polyurethane and heat-insulating putty, and thermal insulation adhesives such as asbestos diatomaceous earth and magnesium carbonate asbestos powder.
[0054] By applying an insulating coating to the outer wall of the connecting pipe 230, the connecting pipe 230 is effectively insulated, maintaining the inner wall temperature of the connecting pipe 230 above the condensation point of the volatiles. This prevents substances such as magnesium and magnesium chloride from condensing when flowing through the observation window 110 area, ensuring continuous light transmission through the observation window 110. Furthermore, it allows the temperature signal received by the infrared imager 120 to accurately reflect the temperature changes of the airflow inside the connecting pipe 230, avoiding contamination of the observation window 110 and interference with the temperature signal caused by condensation of volatiles due to localized low temperatures in the connecting pipe 230. This improves the accuracy of the infrared imager 120's detection results and enhances the judgment precision of the distillation endpoint determination device 100.
[0055] In some possible embodiments provided by this utility model, the processing module includes an alarm, and the processing module is configured to trigger the alarm to send alarm information when it is determined that the distillation endpoint has been reached.
[0056] In this embodiment, when the processing module determines that the system has reached the distillation endpoint based on the temperature distribution characteristics of the thermal image from the infrared imager 120, it triggers an alarm to send an alarm message, reminding and notifying the operator that the sponge titanium distillation production system 200 has reached the distillation endpoint, achieving complete distillation for subsequent operations. This achieves automated monitoring and determination of the distillation endpoint of the sponge titanium distillation production system 200, improving the accuracy and timeliness of endpoint determination.
[0057] An embodiment of this utility model also provides a sponge titanium distillation production system 200, including: the distillation endpoint determination device 100 of any of the foregoing embodiments. Since the sponge titanium distillation production system 200 includes the aforementioned distillation endpoint determination device 100, it has all the technical effects of the aforementioned distillation endpoint determination device 100, which will not be described in detail here.
[0058] Furthermore, the method for determining the distillation endpoint of the sponge titanium distillation production system 200 using the distillation endpoint determination device 100 provided in this embodiment of the invention is as follows:
[0059] Before distillation, an infrared imager 120 is used to collect a thermal image through the observation window 110. The thermal image shows that the area of the observation window 110 has a uniform low temperature and brightness / color distribution. Since no high-temperature gas passes through the connecting pipe 230 before distillation, this temperature field can be roughly understood as the temperature field of the cold plate 130, which can be used as a reference for judging the end of distillation.
[0060] Distillation begins, and an infrared imager 120 is used to acquire a thermal image in real time through the observation window 110.
[0061] In the initial stage of distillation, a large amount of high-temperature volatile gas (approximately 800°C to 900°C) continuously flows through the connecting pipe 230. At this time, the thermal image acquired by the infrared imager 120 shows that the observation window 110 area is filled with high temperature and has a uniform brightness / color distribution or a turbulent distribution.
[0062] As distillation proceeds, the volatiles gradually decrease. When distillation is complete, the high-temperature gas in the connecting pipe 230 disappears, and the characteristics of the thermal image captured by the infrared imager 120 change to: the observation window 110 area exhibits a uniform low temperature and brightness / color distribution, and its temperature field is consistent with the temperature field of the cold plate 130. Therefore, when the processing module detects that the thermal image has changed from a high-temperature distribution state to a uniform low-temperature distribution state, that is, when the thermal image reaches the reference parameters provided by the cold plate 130, it can determine that the distillation has reached its complete state and the distillation endpoint has been reached, and trigger the alarm to issue an alarm message to notify the operator.
