[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] The following disclosure provides many different embodiments or examples for implementing different structures of the embodiments of the present application. In order to simplify the disclosure of the embodiments of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present application. In addition, the reference numerals and / or letters in different examples can be repeated in the embodiments of the present application. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed.

[0032] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure.

[0033] To address the problems in the prior art, this application provides a distillation mechanism and a petroleum product testing device, which saves labor and improves work efficiency while meeting operational standards.

[0034] Fig. 1 This illustration shows a structural diagram of a distillation mechanism provided in this application when the sealing assembly is sealed to the sample bottle; Fig. 2 This illustration shows a structural diagram of a distillation mechanism provided in this application when the sealing assembly is separated from the sample bottle; Fig. 3 This is a top view of a box structure provided in an embodiment of this application.

[0035] like Figs. 1-3 As shown in the embodiment of this application, a distillation mechanism is provided, which is applied to a petroleum product testing equipment. The petroleum product testing equipment includes a support plate 1, on which a positioning hole for positioning a sample bottle 7 is provided. The distillation mechanism includes: a lifting assembly 2, which is disposed below the support plate 1, and includes a vertically movable support plate 21 for lifting the sample bottle 7; a heating assembly 3, which is disposed on the support plate 21 for heating the sample bottle 7; a condensing assembly 4, which is disposed above the support plate 1, and includes a housing 41, which has a condensing chamber 411 and a communicating hole communicating with the condensing chamber 411, the communicating hole communicating with the bottle mouth 721 of the sample bottle 7; and a sealing assembly 5, which is disposed at the communicating hole of the condensing chamber 411 for sealing the bottle mouth 721 of the sample bottle 7.

[0036] In this application, the design of the present invention achieves a high degree of automation during the distillation determination process of petroleum products. For example, when determining the distillation characteristics of gasoline or diesel, the operator only needs to place the sample bottle 7 into the positioning hole, and the entire distillation process can be automatically performed. The lifting assembly 2 automatically lifts the sample bottle 7 to the appropriate position, the heating assembly 3 precisely controls the temperature, and the condensing assembly 4 and the sealing assembly 5 ensure effective condensation of the vapor and sealing of the system. This automated design not only improves operational efficiency but also significantly reduces human error, making it particularly suitable for petroleum quality control laboratories that require large-scale sample testing.

[0037] Furthermore, when determining the distillation curves of petroleum products with different boiling point ranges, such as aviation kerosene, the design of the heating assembly 3 placed on the support plate 21 allows the heat source to directly and uniformly heat the sample bottle 7. This design ensures precise control of the heating process, which helps to obtain accurate distillation curves. For example, when determining the 10%, 50%, and 90% recovery temperatures of aviation kerosene, precise temperature control can improve the accuracy of these critical parameters, which are 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 condensing assembly 4 and the sealing assembly 5 plays a crucial role. The condensing cavity 411 provides sufficient condensing space to ensure that the vapor can be fully condensed. At the same time, the sealing assembly 5 effectively prevents the escape of light components, which is essential to ensure the accuracy of the test results. For example, when determining the initial boiling point and final boiling point of gasoline, good condensation and sealing can ensure the capture of the full range of fractions, improving the reliability of the results.

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

[0040] When handling flammable and explosive petroleum products, the closed structure of the present design greatly improves operational safety. The closed system formed by the condensing assembly 4 and the sealing assembly 5 effectively prevents the leakage of volatile components, reducing the risk of fire and explosion. This feature is particularly important when testing highly volatile products (such as light naphtha), significantly improving 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 is in abutment with 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 for abutting against the bottle mouth 721 on the bottle cap 72.

[0042] In the present application, when performing high-temperature distillation tests, such as determining the distillation characteristics of heavy diesel oil, 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 remains in a stable position during the entire distillation process, even at high temperatures, preventing leakage or positional deviation due to thermal expansion. For example, when determining the 95% recovery temperature of diesel oil, this design ensures that high-boiling components do not escape due to poor sealing, improving the accuracy of test results.

[0043] When multiple samples need to be tested continuously, such as batch product testing in a refinery quality control laboratory, 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 the need to adjust other components, greatly shortening the sample replacement time and improving test efficiency. For example, when performing continuous quality monitoring of gasoline blending batches, the distillation characteristics of multiple samples can be quickly tested, providing timely feedback for production adjustment needs.

[0044] The standard bottle mouth 721 design on the bottle cap 72 provides convenience for 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 ensures the compatibility of the equipment, reducing test errors caused by differences in sample containers.

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

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

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

[0048] In long-term continuous testing processes, such as online quality monitoring in oil refineries, the detection assembly can timely detect abnormal situations. For example, if the reflux is detected to suddenly stop or the rate is abnormal, the system can immediately alarm and stop heating to prevent the sample from overheating or dry burning. This function is particularly important when dealing with unknown samples or testing new products, and can effectively prevent equipment damage and safety accidents.

[0049] In some embodiments, the distillation mechanism further comprises a reflux tube 42 in communication with the condensation cavity 411, and the bottom of the reflux tube 42 is located directly above the bottle opening 721.

[0050] In this application, when determining the distillation characteristics of volatile petroleum products, such as light gasoline, the design of the reflux tube 42 ensures that the condensed liquid can directly and completely reflux into the sample bottle 7. The design of the reflux tube 42 at the bottom of the bottle opening 721 minimizes the loss of liquid during reflux. For example, when determining the content of low-boiling components (such as C4-C6 hydrocarbons) in gasoline, this design can ensure that these volatile components can be accurately captured and measured, improving the accuracy of the test results.

[0051] In continuous testing of different samples, such as distillation characteristics comparison of crude oils from different origins in a crude oil evaluation laboratory, the design of the reflux tube 42 can effectively prevent cross-contamination between samples. After each test is completed, the residual liquid in the reflux tube 42 will completely reflux into the original sample bottle 7 and will not affect the testing of the next sample. This design is particularly suitable for scenarios that require high-precision comparison of the distillation characteristics of different samples, such as crude oil price evaluation or analysis of the characteristics of new oilfield products.

[0052] The design of the reflux tube 42 also provides a window for the operator to visually observe the condensation process. In manual or semi-automatic testing mode, the operator can observe the flow of liquid in the reflux tube 42 to determine the progress of the distillation process. For example, when determining the 90% recovery temperature of diesel oil, the operator can predict the approaching final boiling point by observing the change in reflux rate, thereby more accurately controlling the heating process.

[0053] Specifically, the reflux pipe 42 can be a straight pipe, and a buffer portion 422 can also be provided on the straight pipe. The buffer portion 422 is a spherical cavity in communication with the straight pipe. The buffer portion 422 can buffer the airflow in the reflux pipe 42, and can increase the heat exchange area with the condensation cavity 411, thereby improving the condensation effect.

[0054] In some embodiments, the bottom of the reflux pipe 42 is provided with an inclined surface structure 421. The inclined surface structure 421 is used to guide the liquid in the reflux pipe 42. The detection end of the detection assembly is aligned with the inclined surface structure 421.

[0055] In this 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, facilitating the detection assembly to accurately capture each drop of reflux liquid. This design greatly improves the accuracy of volume measurement, especially when determining key parameters such as initial boiling point and final boiling point. For example, when determining the 10% recovery temperature of jet fuel, accurate drop count can provide more accurate volume percentage data.

[0056] When determining high-boiling petroleum products, such as heavy diesel or lubricating oil base oil, the reflux speed can become very slow. The inclined surface structure 421 can effectively guide the slow reflux droplets, ensuring that they are accurately captured by the detection assembly even at low reflux rates. This is particularly useful for drawing fine distillation curves in the high-boiling range, providing more detailed product component 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 utilizes gravity to ensure that even high-viscosity droplets can flow smoothly to the detection point. This design improves the adaptability of the test, enabling the device to maintain high precision under various environmental conditions.

[0058] The design of the inclined surface structure 421 also facilitates cleaning and maintenance of the device. After testing different types of petroleum products, residues may accumulate at the bottom of the reflux pipe 42. The inclined surface design allows cleaning liquid to more easily flush the entire surface, ensuring 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 assembly 6. The refrigeration assembly 6 includes a refrigeration end and a heat dissipation end. The refrigeration end of the refrigeration assembly 6 is located in the condensation cavity 411.

[0060] In this application, the presence of the refrigeration assembly 6 can significantly improve the condensation efficiency when determining low-boiling petroleum products, such as light gasoline or naphtha. The refrigeration end located within the condensation cavity 411 can directly reduce the temperature inside the cavity, accelerating the vapor condensation process. For example, when determining the content of C4-C6 light components in gasoline, high-efficiency condensation can ensure that these volatile components are completely captured, improving the accuracy of test results.

[0061] For petroleum products of different boiling point ranges, the refrigeration assembly 6 can flexibly adjust the condensation temperature. When testing high-boiling products, such as heavy diesel, the refrigeration intensity can be reduced; while testing low-boiling 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 regions, the refrigeration assembly 6 can effectively overcome the influence of environmental temperature, ensuring the stability of the condensation effect. This is crucial for ensuring the consistency and comparability of test results, especially when comparing the quality of petroleum products across different climates.

[0063] Compared with traditional water cooling systems, the refrigeration assembly 6 can achieve closed-loop cooling without the need for continuous supply of cooling water. This not only saves water resources, but also reduces operating costs. In arid regions or laboratories with limited water resources, this design is particularly valuable, ensuring the continuous operation of testing work 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 within the condensation cavity 411 and forms a refrigeration end, and the other end is located outside the box 41.

[0065] In this application, the semiconductor refrigeration plate 61 can achieve rapid and precise temperature regulation. When determining petroleum products of 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 determining the initial boiling point of gasoline, a lower temperature can be set; while determining the final boiling 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 traditional compression refrigeration systems, the temperature regulation response of the semiconductor refrigeration plate 61 is faster. This is particularly useful when quickly switching between different types of sample testing. For example, in a petroleum product quality control laboratory, the condensation temperature can be quickly adjusted to meet the testing needs of different batches or different types of products, greatly improving testing efficiency.

[0067] The design of one end of the semiconductor refrigeration plate 61 being located in the condensation cavity 411 and the other end being 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 testing equipment with limited space.

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

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

[0070] In this application, the fan 62 blows air on the end of the semiconductor refrigeration plate 61 located 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 full boiling range analysis of crude oil, long-term continuous heating and condensation processes may be required, and efficient heat dissipation can ensure the stability of refrigeration performance, thereby ensuring the accuracy of test results.

[0071] Through effective heat dissipation, the fan 62 can prevent the semiconductor refrigeration plate 61 from overheating and prolong its service life. This is particularly valuable in industrial laboratories with high-intensity use, which can reduce equipment maintenance costs and improve equipment reliability.

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

[0073] In combination with temperature sensors, the fan 62 can be intelligently controlled. The system can automatically adjust the fan 62 speed based on ambient temperature and condensation requirements, ensuring refrigeration effectiveness while avoiding unnecessary energy consumption. This intelligent control can significantly improve energy efficiency in scenarios that require long-term continuous operation, such as real-time quality monitoring systems in oil refineries.

[0074] In some embodiments, the support plate 21 is provided with positioning grooves for positioning the sample bottle 7.

[0075] In this application, the positioning grooves can ensure that the sample bottle 7 maintains a stable position during heating. This is particularly important when determining high-precision distillation curves, such as strict quality control tests for aviation kerosene. Precise positioning can ensure uniform heating and avoid test errors caused by the sample bottle 7 shifting position.

[0076] The design of the positioning slots facilitates automated sample replacement. In scenarios requiring the testing of multiple samples in succession, such as batch product quality testing in oil refineries, a robotic arm or automated system can precisely place sample bottles 7 into the positioning slots, enhancing operational efficiency and accuracy.

[0077] During high-temperature testing processes, such as determining the high-temperature fractions of heavy fuel oil, the positioning slots prevent the sample bottles 7 from shifting due to thermal expansion or vibrations. This design enhances operational safety and reduces the risk of sample leakage or breakage.

[0078] By designing positioning slots of different sizes or adjustable dimensions, the device can accommodate various specifications of sample bottles 7. This flexibility allows the device to be used for testing petroleum products under different standard requirements, such as ASTM, IP, or GB standards, increasing the device's versatility.

[0079] When determining the distillation characteristics of gasoline or diesel, the operator only needs to place the sample bottles 7 into the positioning holes, and the entire distillation process can be automatically performed. The lifting assembly 2 automatically lifts the sample bottles 7 to the appropriate position, the heating assembly 3 precisely controls the temperature, and the condensing assembly 4 and the sealing assembly 5 ensure effective condensation of vapors and the sealing of the system. This automated design not only improves operational efficiency but also significantly reduces human error, saving labor and improving work efficiency while meeting operational standards.

[0080] The present application provides a petroleum product testing device, which includes the aforementioned distillation mechanism.

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

[0082] The automated lifting assembly 2, precise heating control, efficient condensing system, and intelligent detection assembly work together to significantly improve testing efficiency and accuracy. This is particularly valuable in scenarios requiring large-scale sample testing, such as quality control laboratories in oil refineries or rapid testing at petroleum product wholesale terminals.

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

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

[0085] The equipment integrated with advanced detection and control systems can achieve automatic data acquisition, storage, and analysis. This provides the basis for establishing a complete product quality database, which helps to conduct long-term quality trend analysis, product formula optimization, and production process control. In modern intelligent refineries and large petroleum product quality monitoring centers, such data management capabilities are particularly important.
