[0028] Example 1
[0029] like Figures 1 to 5As shown, this embodiment provides a kerosene sample quantitative mixing and distribution system, including a sampling container group, a quantitative collection device 2, a stirring device 4, a quantitative dispensing device 5, and a collection container 7. The sampling container group includes multiple sampling containers 1, each used to hold different types of kerosene. The number of sampling containers 1 matches the number of different types of kerosene, where the types of kerosene mainly refer to kerosene with different water content and densities. For example, it may include three sampling containers 1, each containing kerosene samples taken from three different heights within the same container (from the top 1 / 6 height, the middle 1 / 2 height, and the bottom 1 / 6 height). Due to long-term storage and sedimentation, these samples will have different water content and densities, with the density increasing sequentially from the top to the bottom of the container. The quantitative collection device 2 is used to quantitatively transfer the kerosene from each sampling container 1 to the stirring device 4. The quantitative dispensing device 5 is used to transfer the mixed kerosene from the stirring device 4 to the collection container 7.
[0030] Working principle:
[0031] S1. Oil sample loading: Load the kerosene samples to be mixed (aviation kerosene samples or other kerosene samples) into each sampling container 1 respectively;
[0032] S2. Parameter setting: Set the working parameters (such as mixing ratio, distribution amount, etc.) for the quantitative acquisition device 2 and the quantitative discharging device 5;
[0033] S3. Oil sample collection and quantification: The quantitative collection device 2 collects and quantifies the kerosene samples from each sampling container 1 and sends them into the stirring device 4.
[0034] S4. Stirring and mixing: Stirring device 4 mixes the collected kerosene samples to form mixed kerosene;
[0035] S5. Mixed kerosene collection: The quantitative discharge device 5 sends the mixed kerosene in the stirring device 4 into the collection container 7.

The liquid delivery pipe is equipped with an inlet solenoid valve 3, which is used to open and close the kerosene sample to achieve the delivery and cessation of delivery. The outlet end of the quantitative discharge device 5 is equipped with an outlet pipe that extends into the collection container 7. The outlet pipe is equipped with an outlet solenoid valve 6, which is used to open and close the mixed kerosene to achieve the delivery and cessation of delivery.
[0037] In one embodiment, a control system is also included. The quantitative acquisition device 2, the stirring device 4, the quantitative discharging device, the liquid inlet solenoid valve 3, and the liquid outlet solenoid valve 6 are all electrically connected to the control system to realize the automated control of the kerosene sample quantitative mixing and distribution system.
[0038] In one embodiment, the control system includes an instruction device 9 and a controller 10, which are electrically connected. The instruction device 9 includes a touch control screen, through which instructions are set and sent to the controller 10. The quantitative acquisition device 2, the stirring device 4, the quantitative discharge device 5, the liquid inlet solenoid valve 3, and the liquid outlet solenoid valve 6 are all electrically connected to the controller 10, and the controller 10 controls the quantitative acquisition device 2, the stirring device 4, the quantitative discharge device 5, the liquid inlet solenoid valve 3, and the liquid outlet solenoid valve 6.
[0039] The touch control screen can be either a resistive or capacitive touchscreen, providing an intuitive and easy-to-use user experience for operators to set system parameters and monitor status. The touch control screen includes power and adjustment buttons. Preferably, the controller 10 can be a Siemens 6ES7-300 series controller, possessing powerful computing capabilities and expandability to ensure efficient and automated system operation. It mainly includes a power module, CPU module, analog input module, analog output module, serial communication module, and memory card, which records the entire process. During operation, the controller 10 collects data such as the mixing ratio, flow rate, and distribution volume of the oil sample in real time and stores it on the memory card for subsequent quality traceability and system optimization. Data can also be exported to external devices via the serial communication module for further analysis and recording.
[0040] In one embodiment, the quantitative sampling device 2 includes a distribution-type peristaltic pump. The inlet ends of multiple hoses of the distribution-type peristaltic pump extend into multiple sampling containers 1, and the outlet ends of the multiple hoses are connected to the inlet end of the stirring device 4 via a delivery pipe, thereby realizing the quantitative delivery of kerosene samples from multiple sampling containers 1. The distribution-type peristaltic pump can control the liquid flow rate and distribution volume in each hose, achieving precise quantitative distribution of the oil sample. The quantitative dispensing device 5 includes a flow-type peristaltic pump. The inlet end of the flow-type peristaltic pump hose is connected to the outlet end of the stirring device 4, and the outlet end of the flow-type peristaltic pump hose is connected to an outlet pipe, thereby realizing the quantitative output of mixed kerosene. In another embodiment, the quantitative sampling device 2 includes multiple flow-type peristaltic pumps, the number of which corresponds to the number of sampling containers 1, with the hose of each flow-type peristaltic pump extending into a corresponding sampling container 1.

The collection container 7 is made of a corrosion-resistant material.
[0042] In one embodiment, a waste liquid container 8 is also included, which is used to collect the mixed kerosene remaining after the stirring device 4 has delivered it to the collection container 7, so as to empty the mixed kerosene in the stirring device 4 for the next mixing.
[0043] In one embodiment, the stirring device 4 employs an electric stirrer or a magnetic stirrer. The electric stirrer uses a high-efficiency, low-noise motor to drive the stirring rod. The magnetic stirrer typically includes a stirring container 41, a container lid 42, a stirring base 43, and a stirring rotor 44. The stirring container 41 is placed on the stirring base 43, and the container lid 42 seals the opening of the stirring container 41. The stirring rotor 44 is a polytetrafluoroethylene (PTFE) magnetic rotor placed inside the stirring container 41. A start switch is provided on the stirring base 43; upon startup, the magnetic drive device inside the stirring rotor 44 drives the rotor 44 to rotate, stirring the liquid inside the stirring container 41. The stirring rotor 44 is typically capsule-shaped. Both the stirring container 41 and the container lid 42 are made of corrosion-resistant glass. The volume of the stirring container 41 can be selected as needed, such as a 5L stirring container 41.
[0044] In one embodiment, the stirring device 4 employs a magnetic stirrer. It also includes an ultrasonic cleaner 11 for cleaning the stirring container 41 of the magnetic stirrer. The inclusion of the ultrasonic cleaner 11 and the waste liquid container 8 ensures the cleanliness of the interior of the stirring device 4, avoids cross-contamination, and reduces the environmental impact of waste liquid.
[0045] Through the above technical solutions, this kerosene sample quantitative mixing and dispensing system can achieve efficient, accurate, and automated mixing and dispensing of aviation kerosene samples, reducing manual operation, significantly improving work efficiency and sample consistency, and solving the problems of low efficiency, large errors, and high contamination risks caused by traditional manual operation. It meets the stringent requirements of aviation fuel quality testing and production processes. By employing a high-precision peristaltic pump and solenoid valves, the system can precisely control the collection volume of each sample, ensuring a mixing ratio and dispensing accuracy of up to 1%, greatly improving the precision of oil sample mixing and dispensing.
[0046] In one embodiment, each pipeline in the system can be a pipeline with an insulation layer.

[0048] like Figures 1 to 5 As shown, this embodiment provides a method for quantitative mixing and dispensing of kerosene samples, including the following steps:
[0049] Oil sample loading: The staff will load the kerosene samples to be mixed (aviation kerosene samples or other kerosene samples) into each sampling container 1. Specifically, kerosene samples with different water content and density will be placed into different sampling containers 1. For example, prepare three sampling containers 1 and put three kerosene samples with different heights from the same tank into the three sampling containers 1 respectively.
[0050] Parameter settings: Set the working parameters (such as mixing ratio, distribution amount, etc.) for the quantitative acquisition device 2 and the quantitative discharging device 5;
[0051] Oil sample collection and quantification: The quantitative collection device 2 collects and quantifies the kerosene samples from each sampling container 1 and sends them into the stirring device 4;
[0052] Stirring and mixing: Stirring device 4 mixes the collected kerosene samples to form mixed kerosene;
[0053] Mixed kerosene collection: The metering discharge device 5 sends the mixed kerosene in the stirring device 4 into the collection container 7.
[0054] In one embodiment, during the parameter setting step, the operating parameters are set by the instruction device 9.
[0055] In one embodiment, during oil sample collection and quantification, the controller 10 accurately collects and quantitatively distributes kerosene samples in each sampling container 1 according to set parameters through the quantitative collection device 2 (e.g., a distribution peristaltic pump) and the liquid inlet solenoid valve 3.
[0056] In one embodiment, during the mixing process, the controller 10 activates the stirring device 4 to efficiently mix the collected kerosene sample. During the mixing process, the stirring rod or stirring rotor 44 of the stirring device 4 operates according to a preset rotation speed and time to ensure the sample is sufficiently homogeneous. Simultaneously, the controller 10 monitors the flow rate and stirring status in real time to ensure that the set mixing requirements are met.
[0057] In one embodiment, the waste liquid treatment step is also included: after the collection container 7 completes the collection, the quantitative discharge device 5 sends all the remaining mixed kerosene in the stirring device 4 into the waste liquid container 8.
[0058] In one embodiment, the method further includes a step of cleaning the stirring device: after all the remaining mixed kerosene in the stirring device 4 is sent into the waste liquid container 8, the stirring container 41 of the stirring device 4 is removed and sent into the ultrasonic cleaner 11, and the stirring container 41 is cleaned by ultrasonic waves to ensure that subsequent operations are not affected by residual samples and to reduce the risk of cross-contamination.
[0059] In one embodiment, the method further includes data storage and output: during operation, the controller 10 collects data such as the mixing ratio, flow rate, and distribution volume of the oil sample in real time and stores them in a memory card for subsequent quality traceability and system optimization. The data can also be exported to an external device via a serial communication module for further analysis and recording.
