[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0033] In order to solve the problems in the prior art, the present application provides a distillation mechanism and a petroleum product measuring device, which saves manpower and improves work efficiency while meeting operating standards.

[0034] Figure 1 A schematic diagram showing the structure of a distillation mechanism provided by an embodiment of the present application when a sealing component is sealed with a sample bottle; Figure 2 A schematic diagram showing the structure of a distillation mechanism provided by an embodiment of the present application when the sealing component is separated from the sample bottle; Figure 3 A schematic diagram of the top structure of a box provided in an embodiment of the present application is shown.

[0035] like Figure 1-3 As shown, an embodiment of the present application provides a distillation mechanism, which is applied to a petroleum product measuring device. The petroleum product measuring device includes a support plate 1, and a positioning hole for positioning a sample bottle 7 is provided on the support plate 1; the distillation mechanism includes: a lifting component 2, which is arranged below the support plate 1, and the lifting component 2 includes a support plate 21 that can move in a vertical direction, and the support plate 21 is used to lift the sample bottle 7; a heating component 3, which is arranged on the support plate 21 and is used to heat the sample bottle 7; a condensation component 4, which is arranged above the support plate 1, and the condensation component 4 includes a box body 41, and the box body 41 has a condensation chamber 411 and a connecting hole connected to the condensation chamber 411, and the connecting hole is used to connect to the bottle mouth 721 of the sample bottle 7; and a sealing component 5, which is arranged at the connecting hole of the condensation chamber 411 and is used to seal the bottle mouth 721 of the sample bottle 7.

[0036] In the present application, the design of the present invention realizes a high degree of automation in the process of determining the distillation of petroleum products. For example, when determining the distillation characteristics of gasoline or diesel, the operator only needs to put the sample bottle 7 into the positioning hole, and the entire distillation process can be carried out automatically. The lifting component 2 automatically lifts the sample bottle 7 to the appropriate position, the heating component 3 accurately controls the temperature, and the condensation component 4 and the sealing component 5 ensure the effective condensation of steam and the sealing of the system. This automated design not only improves the operating efficiency, but also greatly reduces human errors, and is particularly suitable for petroleum quality control laboratories that need to test large quantities of samples.

[0037] Moreover, when measuring petroleum products with different boiling point ranges, such as the distillation curve of aviation kerosene, the design that the heating assembly 3 is arranged on the support plate 21 allows the heat source to directly and evenly heat the sample bottle 7. This design ensures precise control of the heating process and helps to obtain an accurate distillation curve. For example, when measuring the 10%, 50% and 90% recovery temperatures of aviation kerosene, precise temperature control can improve the measurement accuracy of these key parameters, which is crucial for evaluating fuel quality and performance.

[0038] When determining the distillation characteristics of volatile petroleum products, such as light gasoline, the design of the condensation assembly 4 and the sealing assembly 5 plays a key role. The condensation chamber 411 provides sufficient condensation space to ensure that the steam can be fully condensed. At the same time, the sealing assembly 5 effectively prevents the escape of light components, which is crucial to ensure the accuracy of the test results. For example, when determining the initial distillation point and final distillation point of gasoline, good condensation and sealing effects can ensure that the full range of distillates are captured, improving the reliability of the results.

[0039] The design of the present invention is applicable to the distillation determination of various types of petroleum products: for light petroleum products (such as gasoline), the system can quickly heat up and effectively condense low-boiling components; for medium-quality petroleum products (such as diesel), it can slowly heat up through precise temperature control to obtain detailed distillation curves; for heavy petroleum products, the system's high-temperature heating capacity and effective sealing design can ensure the accuracy of the test. This wide applicability allows the same set of equipment to be used for the testing of a variety of petroleum products, improving the equipment utilization rate and testing efficiency of the laboratory.

[0040] The closed structure of this design greatly improves the safety of operation when handling flammable and explosive petroleum products. The closed system formed by the condensation component 4 and the sealing component 5 effectively prevents the leakage of volatile components and reduces the risk of fire and explosion. This feature is particularly important when testing highly volatile products (such as light naphtha) and can significantly improve the safety level of the laboratory.

[0041] In some embodiments, the sample bottle 7 includes a bottle body 71 and a bottle cap 72 arranged on the bottle body 71, the bottle body 71 is located in the positioning hole, the bottle cap 72 abuts against the top of the support plate 1, and a bottle mouth 721 is arranged on the bottle cap 72; the sealing assembly 5 is used to abut against the bottle mouth 721 on the bottle cap 72.

[0042] In the present application, when conducting high temperature distillation tests, such as determining the distillation characteristics of heavy diesel, the abutment design of the bottle cap 72 and the top of the support plate 1 provides additional sealing and stability. This structure ensures that the sample bottle 7 can maintain a stable position even at high temperatures throughout the distillation process, preventing leakage or positional displacement caused by thermal expansion. For example, when determining the 95% recovery temperature of diesel, this design can ensure that high boiling point components will not escape due to poor sealing, thereby improving the accuracy of the test results.

[0043] When multiple samples need to be tested continuously, such as when a refinery's quality control laboratory performs batch product testing, this design allows for quick replacement of the sample bottle 7. The operator only needs to replace the entire sample bottle 7 (including the bottle body 71 and the bottle cap 72) without adjusting other components, which greatly shortens the sample replacement time and improves testing efficiency. For example, when performing continuous quality monitoring of gasoline blending batches, the distillation characteristics test of multiple samples can be completed quickly, and production adjustment needs can be fed back in a timely manner.

[0044] The standard bottle mouth 721 provided on the bottle cap 72 is designed to facilitate the cooperation with the sealing assembly 5. This standardized interface ensures that sample bottles 7 of different batches or specifications can be perfectly matched with the equipment, improving the versatility and flexibility of the equipment. For example, when testing petroleum products of different brands or sources, the standardized interface design can ensure the compatibility of the equipment and reduce the test errors caused by differences in sample containers.

[0045] In some embodiments, the distillation mechanism further includes a detection component, which is used to detect liquid reflux of the condensation component 4, and the detection component is electrically connected to the heating component 3 through a controller.

[0046] In the present application, when measuring a petroleum product with complex components, such as the distillation curve of aviation kerosene, the detection component can monitor the reflux of the condensate in real time. Through the electrical connection with the controller, the system can automatically adjust the power of the heating component 3 according to the reflux rate. For example, when measuring the distillation curve of aviation kerosene, the system can automatically adjust the heating rate after detecting the initial distillation point to ensure an ideal recovery rate of 4-5 mL per minute, which greatly improves the accuracy and repeatability of the test.

[0047] When conducting standard distillation tests, such as determining the distillation characteristics of gasoline, the detection component can accurately identify the initial distillation point, each percentage recovery point and the final distillation point. This automatic recognition function not only improves the accuracy of the test, but also reduces the operator's subjective judgment error. For example, when determining the T50 (50% recovery temperature) of gasoline, the system can accurately capture the moment of 50% volume recovery, record the corresponding temperature, and provide more objective and reliable data.

[0048] During long-term continuous testing, such as online quality monitoring in refineries, the detection components can detect abnormal conditions in a timely manner. For example, if a sudden stop or abnormal rate of reflux is detected, the system can immediately alarm and stop heating to prevent the sample from overheating or dry burning. This function is particularly important when processing unknown samples or conducting new product development tests, which can effectively prevent equipment damage and safety accidents.

[0049] In some embodiments, the distillation mechanism further includes a reflux pipe 42 connected to the condensation chamber 411 , and the bottom of the reflux pipe 42 is located directly above the bottle mouth 721 .

[0050] In the present application, when determining the distillation characteristics of volatile petroleum products, such as light gasoline, the design of the reflux pipe 42 ensures that the condensate can flow back directly and completely into the sample bottle 7. The design that the bottom of the reflux pipe 42 is located just above the bottle mouth 721 minimizes the loss of liquid during the reflux process. For example, when determining the content of low-boiling point components (such as C4-C6 hydrocarbons) in gasoline, this design can ensure that these volatile components can be accurately captured and measured, thereby improving the accuracy of the test results.

[0051] When continuously testing different samples, such as when a crude oil evaluation laboratory compares the distillation characteristics of crude oils from different origins, the design of the reflux pipe 42 can effectively prevent cross-contamination between samples. After each test, the residual liquid in the reflux pipe 42 will completely flow back into the original sample bottle 7, without affecting the test of the next sample. This design is particularly suitable for scenarios where high-precision comparison of the distillation characteristics of different samples is required, such as crude oil price evaluation or new oil field product characteristics analysis.

[0052] The design of the reflux pipe 42 also provides the operator with a window for visually observing the condensation process. In the manual or semi-automatic test mode, the operator can judge the progress of the distillation process by observing the flow of the liquid in the reflux pipe 42. For example, when measuring the 90% recovery temperature of diesel, the operator can predict that the terminal distillation point is about to be reached by observing the change in the reflux rate, thereby controlling the heating process more accurately.

[0053] Specifically, the return pipe 42 can be a straight pipe, and a buffer portion 422 can be set on the straight pipe. The buffer portion 422 is a spherical cavity connected to the straight pipe. The buffer portion 422 can buffer the airflow in the return pipe 42 and increase the heat exchange area with the condensation chamber 411, thereby improving the condensation effect.

[0054] In some embodiments, a slope structure 421 is disposed at the bottom of the reflux pipe 42 . The slope structure 421 is used to drain the liquid in the reflux pipe 42 . The detection end of the detection component is aligned with the slope structure 421 .

[0055] In the present application, when performing precise distillation curve determination, such as determining the detailed distillation characteristics of aviation kerosene, the design of the inclined surface structure 421 can collect the reflux liquid into a small area, making it easier for the detection component to accurately capture each drop of reflux liquid. This design greatly improves the accuracy of volume measurement, especially when determining key parameters such as the initial distillation point and the final distillation point. For example, when determining the 10% recovery temperature of jet fuel, accurate drop counts can provide more accurate volume percentage data.

[0056] When measuring high boiling point petroleum products, such as heavy diesel or lubricant base oils, the reflux rate may become very slow. The slope structure 421 can effectively guide the slowly refluxed droplets, ensuring that they can be accurately captured by the detection component even at low reflux rates. This is particularly useful for drawing fine distillation curves in the high boiling point range, which can provide more detailed product composition information.

[0057] When testing high viscosity samples in low temperature environments, such as testing heavy fuel oil in cold regions, droplets may stagnate on the plane due to increased viscosity. The inclined surface structure 421 uses gravity to ensure that even high viscosity droplets can flow smoothly to the detection point. This design improves the adaptability of the test and enables the equipment to maintain high accuracy under various environmental conditions.

[0058] The design of the inclined surface structure 421 also facilitates cleaning and maintenance of the equipment. After testing different types of petroleum products, residues may accumulate at the bottom of the return pipe 42. The inclined surface design allows the cleaning liquid to more easily flush the entire surface, ensuring that there are no dead corners, thereby reducing the risk of cross contamination and improving the reliability of continuous testing. This feature is particularly important in laboratories that need to frequently switch between different types of samples, such as comprehensive petroleum product analysis laboratories.

[0059] In some embodiments, the distillation mechanism further includes a refrigeration component 6 , which includes a refrigeration end and a heat dissipation end, and the refrigeration end of the refrigeration component 6 is located in the condensation chamber 411 .

[0060] In the present application, when measuring low-boiling-point petroleum products, such as light gasoline or naphtha, the presence of the refrigeration assembly 6 can significantly improve the condensation efficiency. The refrigeration end is located in the condensation chamber 411, which can directly reduce the temperature in the chamber and accelerate the steam condensation process. For example, when measuring the C4-C6 light component content in gasoline, efficient condensation can ensure that these volatile components are completely captured, thereby improving the accuracy of the test results.

[0061] For petroleum products with different boiling point ranges, the refrigeration component 6 can flexibly adjust the condensation temperature. When testing high boiling point products, such as heavy diesel, the refrigeration intensity can be reduced; while when testing low boiling point products, such as liquefied petroleum gas, the refrigeration intensity can be increased. This flexibility allows the same equipment to meet the testing needs of various petroleum products, improving the versatility of the equipment.

[0062] When testing in high temperature environments, such as petroleum laboratories in tropical areas, refrigeration assembly 6 can effectively overcome the influence of ambient temperature and ensure the stability of the condensation effect. This is crucial to ensure the consistency and comparability of test results, especially when comparing the quality of petroleum products across regions under different climatic conditions.

[0063] Compared with the traditional water cooling system, the refrigeration assembly 6 can achieve closed-loop cooling without the need for a continuous supply of cooling water. This not only saves water resources, but also reduces operating costs. This design is particularly valuable in arid areas or laboratories with water shortages, as it can ensure that testing work can continue without being limited by water resources.

[0064] In some embodiments, the refrigeration assembly 6 includes a semiconductor refrigeration plate 61 , one end of which is located in the condensation chamber 411 and forms a refrigeration end, and the other end of which is located outside the box body 41 .

[0065] In the present application, the semiconductor refrigeration plate 61 can achieve fast and accurate temperature regulation. When measuring petroleum products with different boiling point ranges, such as from light gasoline to heavy diesel, the refrigeration intensity can be quickly changed by adjusting the current. For example, when measuring the initial distillation point of gasoline, a lower temperature can be set; and when measuring the final distillation point of diesel, the temperature can be appropriately increased. This precise temperature control capability helps to obtain a more accurate distillation curve.

[0066] Compared with the traditional compression refrigeration system, the temperature regulation response of the semiconductor refrigeration plate 61 is faster. This is particularly useful when it is necessary to quickly switch between different types of sample tests. For example, in a petroleum product quality control laboratory, the condensation temperature can be quickly adjusted to meet the testing requirements of different batches or different types of products, greatly improving the testing efficiency.

[0067] The design that one end of the semiconductor refrigeration plate 61 is located in the condensation chamber 411 and the other end is outside the box 41 makes the entire refrigeration system compact. This design not only saves space, but also facilitates the installation and maintenance of the equipment. This compact design is particularly valuable for small laboratories or mobile test equipment with limited space.

[0068] The semiconductor refrigeration plate 61 has no complicated mechanical moving parts and is almost noiseless during operation. This can provide a better working environment and reduce noise pollution in scenarios that require long-term continuous operation, such as an online quality monitoring system in an oil refinery.

[0069] In some embodiments, the refrigeration assembly 6 further includes a fan 62 disposed outside the box body 41 , and the fan 62 is used to blow air to one end of the semiconductor refrigeration plate 61 located outside the box body 41 .

[0070] In the present application, the fan 62 blows air to one end of the semiconductor refrigeration plate 61 outside the box 41, which can significantly improve the heat dissipation efficiency. This is particularly important when performing high-intensity or long-term continuous testing. For example, when performing a full-range analysis of crude oil, a long-term continuous heating and condensation process may be required. Efficient heat dissipation can ensure the stability of the refrigeration performance, thereby ensuring the accuracy of the test results.

[0071] By effectively dissipating heat, the fan 62 can prevent the semiconductor refrigeration plate 61 from overheating and extend its service life. This is particularly valuable in industrial laboratories with high intensity of use, which can reduce equipment maintenance costs and improve equipment reliability.

[0072] The design of the fan 62 allows the device to adapt to different ambient temperatures. When working in a higher ambient temperature, the speed of the fan 62 can be increased to enhance heat dissipation; while in a low temperature environment, the speed of the fan 62 can be reduced to save energy. This flexibility allows the device to maintain stable performance in various climatic conditions.

[0073] Combined with the temperature sensor, the fan 62 can be intelligently controlled. The system can automatically adjust the speed of the fan 62 according to the ambient temperature and condensation demand, which not only ensures the refrigeration effect but also avoids unnecessary energy consumption. This intelligent control can significantly improve energy efficiency in scenarios that require long-term continuous operation, such as the real-time quality monitoring system of an oil refinery.

[0074] In some embodiments, a positioning groove for positioning the sample bottle 7 is provided on the support plate 21 .

[0075] In the present application, the positioning groove can ensure that the sample bottle 7 maintains a stable position during the heating process. This is particularly important when determining a high-precision distillation curve, such as a strict quality control test of aviation kerosene. Accurate positioning can ensure uniform heating and avoid test errors caused by the position deviation of the sample bottle 7.

[0076] The design of the positioning slot is conducive to realizing automatic sample replacement. When multiple samples need to be tested continuously, such as batch product quality inspection in an oil refinery, a robotic arm or an automated system can accurately place the sample bottle 7 into the positioning slot, thereby improving operational efficiency and accuracy.

[0077] During high temperature testing, such as determining the high temperature fraction of heavy fuel oil, the positioning groove can prevent the sample bottle 7 from being displaced due to thermal expansion or vibration. This design enhances operational safety and reduces the risk of sample leakage or breakage.

[0078] By designing different sizes or adjustable positioning slots, it can accommodate sample bottles of various specifications 7. This flexibility allows the equipment to be used to test petroleum products with different standard requirements, such as ASTM, IP or GB standards, increasing the versatility of the equipment.

[0079] When the distillation mechanism is used to measure the distillation characteristics of gasoline or diesel, the operator only needs to put the sample bottle 7 into the positioning hole, and the entire distillation process can be carried out automatically. The lifting component 2 automatically lifts the sample bottle 7 to a suitable position, the heating component 3 accurately controls the temperature, and the condensation component 4 and the sealing component 5 ensure the effective condensation of steam and the sealing of the system. This automated design not only improves operating efficiency, but also greatly reduces human errors, saves labor and improves work efficiency while meeting operating standards.

[0080] An embodiment of the present application provides a petroleum product determination device, including the above-mentioned distillation mechanism.

[0081] In this application, by integrating the technical features in all the above claims, the petroleum product determination equipment can achieve comprehensive performance improvement. From sample pretreatment, precise heating, efficient condensation to automatic detection, the entire test process has been optimized. For example, when performing full component analysis of gasoline, the equipment can automatically complete the entire process from low-boiling point components to high-boiling point components, providing detailed and accurate component distribution data.

[0082] The automated lifting components, precise heating control, efficient condensation system and intelligent detection components work together to greatly improve test efficiency and accuracy. This is particularly valuable in scenarios where large batches of samples need to be tested, such as the quality control laboratory of an oil refinery or rapid testing at a wholesale terminal of oil products.

[0083] The equipment is suitable for the determination of various types of petroleum products, from light gasoline to heavy diesel, and even special petroleum products such as aviation fuel or lubricating oil. This wide applicability allows laboratories to complete multiple testing tasks with one set of equipment, improve equipment utilization and reduce overall investment costs.

[0084] The closed design, intelligent control system and multiple safety protection measures (such as overheat protection, leakage detection, etc.) significantly improve the operational safety. This not only protects the safety of operators, but also ensures the stability and reliability of the testing process, which is particularly suitable for handling flammable and explosive petroleum products.

[0085] Equipment integrated with advanced detection and control systems can realize automatic data collection, storage and analysis. This provides a basis for establishing a complete product quality database, which is helpful for long-term quality trend analysis, product formula optimization and production process control. This data management capability is particularly important in modern smart refineries and large-scale petroleum product quality monitoring centers.
