Description

Technical Field

[0001] The present invention relates to the field of aircraft maintenance, and in particular to an intelligent mixing and filling device for aviation kerosene and bactericide. Background Art

[0002] During the long-term use of an aircraft fuel tank, it is prone to microbial contamination. Microbial contamination is mainly caused by bacteria and fungi. These microorganisms use hydrocarbons and water in the fuel as growth media to form biofilms, resulting in blockage of the fuel system and deterioration of fuel quality. Sometimes, microorganisms secrete acids that corrode the inner coating of the fuel tank and damage the sealant in the fuel tank, ultimately leading to fuel leakage. At the same time, pollutant deposits will block the fuel pump and engine fuel filter, resulting in fuel pump failure and reduced engine fuel supply.

[0003] It is crucial to regularly detect whether there are microorganisms in the fuel tank. If contamination is detected, bactericidal treatment must be carried out. During the addition of bactericide, in order to avoid affecting the performance of the fuel itself and the aircraft structure, there are certain restrictions on the dosage of the bactericide. Currently, the batch mixing method or the over-wing method is often used. The batch mixing method requires preparing a large-capacity storage tank in advance to prepare a mixture of aviation kerosene and bactericide. This method has a risk of excessive local mixing concentration outside the aircraft. Then, a pump is used to pump the mixture into the fuel tank and mix it again with the remaining fuel in the fuel tank, and the process is cumbersome. The over-wing method, that is, directly pouring the bactericide from the gravity refueling port, will also cause excessive local concentration of the bactericide and is prone to forming precipitates that block the fuel pump and engine fuel filter. Currently, there is a lack of adjustable metering injection devices in the market, and it is necessary to develop an integrated intelligent equipment with independent and controllable technology.

[0004] For a bactericide filling device for an aircraft fuel tank with a publication number of CN215707215U in a Chinese utility model patent, it discloses a bactericide filling device for an aircraft fuel tank with an indicating control regulating valve. This device controls the bactericide regulating valve through the indication of a bactericide flowmeter, which has high requirements for the working experience of operators. It requires operators to be involved throughout the process. At the same time, it is necessary to manually calculate the refueling time in advance to ensure that the bactericide is added before the end of the refueling time. The degree of equipment intelligence is not high, and only simple stirring is carried out, resulting in poor mixing effect. Summary of the Invention

[0005] To solve the above problems, the purpose of the present invention is to provide an intelligent mixing and filling device for aviation kerosene and bactericide, which can intelligently control the mixing of kerosene and bactericide during the refueling process to ensure the mixing effect.

[0006] The purpose of the present invention is achieved through the following technical solutions:

The central axis and the two rotating tubes are circumferentially evenly provided with multiple blades, each blade is provided with an opening, and the openings on the multiple blades located on the central axis are connected to the bactericide delivery pipeline.

DETAILED DESCRIPTION OF THE INVENTION

[0029] The following is a detailed description of the intelligent mixing and filling device for aviation kerosene and bactericide provided by the present invention in conjunction with the attached Figures 1-3 drawings:

[0030] An intelligent mixing and filling device for aviation kerosene and bactericide includes a housing 1; a three-stage perforated impeller 2; a bactericide distribution bin 3; a bactericide delivery pipeline 4; an intelligent digital display control unit 5; a controller 6; a fuel flow sensor 7; a solenoid valve 8; an electromagnetic diaphragm metering pump 9; a temperature control component 10; a fuel input interface 11; a fuel output interface 12; a grounding coil 13; a capacitive liquid level gauge 14; a bactericide discharge valve 15; a bactericide discharge pipeline 16; a check valve 17; an oil drain pipeline 18; a distribution box 19; an oil drain valve 20; a power plug 21; and an oil delivery pipeline 22.

[0031] The three-stage perforated impeller 2, the bactericide distribution bin 3, the bactericide delivery pipeline 4, the solenoid valve 8, the electromagnetic diaphragm metering pump 9, the temperature control component 10, the controller 6, the distribution box 19, and the check valve 17 are all installed in the internal space of the housing 1, and the fuel flow sensor 7 is nested on the oil delivery pipeline.

[0032] The intelligent digital display control unit 5 is embedded in the housing and communicates with the solenoid valve 8, the electromagnetic diaphragm metering pump 9, the fuel flow sensor 7, the temperature control component 10, the capacitive liquid level gauge 14, the bactericide discharge valve 15, and the oil drain valve 20 through the controller 6.

[0033] The interior of the bactericide distribution bin 3 contains a capacitive liquid level gauge 14, and its lower part is a bactericide temperature control component 10 to ensure that the temperature of the bactericide remains at 15 - 25°C.

[0034] The grounding coil 13 is externally embedded on the housing 1. The grounding coil 13 is used to connect the grounding wire of the aircraft, and at the same time, an anti-static coating is sprayed on the housing 1.

[0035] A bactericide discharge pipeline 16 is connected to the bactericide distribution bin 3, and a bactericide discharge valve 15 is connected to the bactericide discharge pipeline 16 to facilitate the discharge of the remaining bactericide.

[0036] An oil drain pipeline 18 is connected to the oil delivery pipeline 22, and an oil drain valve 20 is connected to the oil drain pipeline 18 to facilitate the discharge of the remaining fuel in the oil delivery pipeline 22 after the fuel filling is completed.

[0037] The bactericide delivery pipeline 4 is connected to the bactericide distribution bin 3, the solenoid valve 8, the electromagnetic diaphragm metering pump 9, the check valve 17, and the three-stage perforated impeller 2; the bactericide distribution bin 3 is used to temporarily store the bactericide; the solenoid valve 8 controls the flow of the bactericide; the check valve 17 prevents the fuel from flowing into the bactericide distribution bin 3; the electromagnetic diaphragm metering pump 9 is used to adjust the flow rate of the bactericide; and the three-stage perforated impeller 2 is used to mix the bactericide and the fuel.

[0038] The intelligent digital display control unit 5 is a touch screen. After writing a program using touch screen software on a computer, it can be downloaded to the touch screen. The controller 6 is a programmable logic controller, namely a PLC. The touch screen controls the PLC, and the PLC feeds back signals to the touch screen. The fuel flow sensor 7 is a liquid turbine flowmeter, and the fungicide discharge valve 15 and the oil drain valve 20 are both solenoid valves.

[0039] The distribution box 19 provides a 24V DC power supply for the touch screen 5, the solenoid valve 8, the fungicide discharge valve 15, the oil drain valve 20, the capacitive liquid level gauge 14, and the fuel flow sensor 7, and provides a 220V AC power supply for the controller 6 and the electromagnetic diaphragm metering pump 9.

[0040] The fuel flow sensor 7 detects the instantaneous fuel flow rate and transmits two parameters, the cumulative fuel flow and the instantaneous fuel flow rate, to the controller 6.

[0041] The three-stage perforated impeller 2 is arranged inside the oil pipeline 22, and the fungicide flows into the oil pipeline 22 through the holes on the three-stage perforated impeller 2, so that the fuel and the fungicide are fully mixed.

[0042] As Figure 3 shown, the three-stage perforated impeller includes a first-stage impeller, a second-stage impeller, and a third-stage impeller; the first-stage impeller includes a central shaft with one end connected to the fungicide delivery pipeline, and a plurality of blades circumferentially and uniformly fixed on the central shaft. The second-stage impeller and the third-stage impeller have the same structure, both including a rotating tube rotating on the central shaft, and a plurality of blades circumferentially and uniformly fixed on the rotating tube. Each blade is provided with an opening. A channel communicating with the fungicide delivery pipeline 4 is arranged inside the central shaft of the first-stage impeller, and the opening on the first-stage impeller communicates with this channel, so that the fungicide flows into the oil pipeline through the channel and the opening to be mixed with the fuel; the first-stage impeller is a stator impeller, and the second-stage impeller and the third-stage impeller are both rotor impellers. The second-stage impeller and the third-stage impeller rotate by the scouring of the fuel.

[0043] Among them, the first-stage impeller is a stator impeller with a channel communicating with the fungicide delivery pipeline inside, which is responsible for accurately introducing the fungicide into the fuel pipeline. Its design includes a guiding structure to ensure that the fungicide flows evenly into the fuel to complete the preliminary mixing; at the same time, as the starting stage of the mixing, the stator impeller can stabilize the flow path of the fuel and the fungicide, avoiding uneven mixing caused by sudden changes in flow rate;

[0044] The second-stage impeller is a rotor impeller that rotates by the scouring force of the fuel. Through the opening design, local turbulence and shear force are generated to break the interface between the fuel and the fungicide, accelerating the diffusion and fusion between the two, and enhancing the dynamic mixing;

[0045] The third-stage impeller is also a rotor impeller. On the basis of the mixing in the second-stage impeller, the third-stage impeller further refines the mixed particles through further rotation and hole-opening actions, ensuring the uniform dispersion of the fungicide in the fuel, avoiding local concentration differences, and achieving refined mixing.

[0046] Finally, the three-stage impellers work together to form a "static-dynamic-dynamic" hierarchical mixing mode. The stator impeller provides the initial mixing conditions, and the rotor impellers gradually strengthen the mixing effect, ultimately achieving efficient and uniform mixing of the fuel and the fungicide.

[0047] Flange plates are provided at the ports of the fuel input interface 11 and the fuel output interface 12, so that different models of fuel pipelines can be assembled for gravity refueling and pressure refueling. The fuel input interface 11 is connected to a fuel truck, and the fuel output interface 12 is connected to the aircraft fuel tank. Generally, a special refueling or fuel-out conversion joint is used to connect between the fuel input interface 11 and the fuel truck or between the fuel output interface 12 and the aircraft fuel tank.

[0048] Usage method of the present invention:

[0049] Before the device operates, the operator needs to correctly connect each component. First, connect the grounding coil 13 to the aircraft body, then power on the power plug 21, and at the same time connect the fuel input interface 11 to the fuel truck and the fuel output interface 12 to the aircraft fuel tank.

[0050] Pour the fungicide product into the fungicide distribution bin 3, and control the temperature control component 10 through the intelligent digital display control unit 5 to heat or cool the fungicide to 15 - 25°C.

[0051] By controlling the intelligent digital display control unit 5 to input the fuel filling amount and the fungicide filling amount, the capacitive liquid level gauge 14 detects the content of the fungicide in the fungicide distribution bin 3. If the content of the fungicide does not meet the requirements, the intelligent digital display control unit 5 will have a page warning prompt to add a certain amount of fungicide additionally. When the content of the fungicide reaches the standard, the fuel flow sensor 7 starts to work to detect whether fuel enters the device, ensuring that the solenoid valve 8 is in the closed state when fuel does not enter the device.

[0052] When performing refueling work, open the fuel delivery switch of the fuel truck, and the fuel will enter the device from the fuel input interface 11 and then flow out from the fuel output interface 12.

[0053] After the fuel flow sensor 7 detects the inflow of fuel into the device, it transmits an electrical signal to the controller 6. The controller 6 sends an open-valve instruction to the solenoid valve 8. At the same time, the controller 6 sends an instruction to the electromagnetic diaphragm metering pump 9. The fuel flow sensor 7 detects the fuel flow rate, and the electromagnetic diaphragm metering pump 9 matches the corresponding bactericide flow rate. The bactericide enters the fuel pipeline 22 through the bactericide delivery pipeline 4. At the same time, the three-stage perforated impeller 2 rotates continuously, enabling the fuel and the bactericide to be fully mixed. After the bactericide filling is completed, the solenoid valve 8 and the electromagnetic diaphragm metering pump 9 are closed. At the same time, a certain refueling time is left to flush the residual bactericide in the oil circuit. When the refueling is completed, the page of the intelligent digital display control unit prompts the end of refueling. At the same time, the intelligent digital display control unit 5 emits a work completion prompt sound, realizing the intelligent monitoring function of the entire filling process.

[0054] During the operation of the device, if the fuel suddenly stops flowing, the fuel flow sensor 7 transmits an electrical signal to the controller 6 and the intelligent digital display control unit 5, and the controller 6 controls the closing of the solenoid valve 8 and the electromagnetic diaphragm metering pump 9.

[0055] After the fuel filling is completed, the drain valve 20 and the bactericide discharge valve 15 can be opened by operating the intelligent digital display control unit 5 to discharge the remaining fuel in the oil pipeline 22 and the remaining bactericide in the bactericide distribution bin 3.

[0056] It can be seen from the above method that:

[0057] This device realizes the intelligent dynamic mixing technology:

[0058] The intelligent digital display control unit 5 is a touch screen, which real-time displays the instantaneous fuel flow rate, the cumulative fuel input flow, the remaining amount of bactericide, and the instantaneous bactericide flow rate. The touch screen can realize two modes: automatic mixing and manual mixing.

[0059] Automatic mixing mode: Enter the total amount of fuel and the amount of bactericide to be filled on the touch screen. If the content of the bactericide to be added is not entered, it is default to add all the bactericides in the bactericide distribution bin 3. By real-time feedback the signal of the total fuel input flow in the fuel flow sensor 7 to the intelligent digital display control unit 5. The intelligent digital display control unit 5 will automatically perform the following operations every two minutes:

[0060]

[0061] Take the calculated remaining fuel filling duration minus 3 minutes as the remaining bactericide filling duration,

[0062]

[0063] The intelligent digital display control unit 5 automatically regulates the power of the electromagnetic diaphragm metering pump 9 so that the bactericide flow rate reaches the operation result.

[0064] Manual mixing: Manually adjust the flow rate of the bactericide through the touch screen.

[0065] Among them, the automatic mixing mode:

[0066] The touch screen can be manipulated to enter the automatic mixing mode

[0067] 1. First, the fuel flow sensor 7 transmits signals to the controller 6 in real time. When the controller 6 receives a signal from the fuel flow sensor 7 indicating that the instantaneous fuel flow rate is not zero, it means that the bactericide injection work can start.

[0068] 2. Then the controller 6 powers on the solenoid valve 8 to open the solenoid valve 8.

[0069] 3. At the same time, the controller 6 sends instructions to the electromagnetic diaphragm metering pump 9, and the electromagnetic diaphragm metering pump 9 starts to work. The bactericide starts to flow, and the controller 6 adjusts the power of the electromagnetic diaphragm metering pump 9 according to the intelligent dynamic mixing technology.

[0070] 4. The capacitive liquid level gauge 14 continuously transmits the bactericide dosage information to the controller 6. When the controller 6 receives the signal that the bactericide dosage is zero or the bactericide has reached the set injection amount, the controller 6 sends instructions to the electromagnetic diaphragm metering pump 9 to stop working, and at the same time sends instructions to the solenoid valve 8 to close the valve.

[0071] 5. The touch screen can be manipulated. The touch screen can control the controller 6 to open and close the drain valve 20 and the bactericide discharge valve 15 to drain the remaining oil in the oil pipeline 22 and the remaining bactericide in the bactericide distribution bin 3.

[0072] In this mode, the electromagnetic diaphragm metering pump 9 needs to operate according to the following formula:

[0073] The instantaneous flow rate of the bactericide (T - 5 min) ≤ the remaining injection amount of the bactericide ≤ the instantaneous flow rate of the bactericide (T - 3 min);

[0074] Among them,

[0075] This formula is an empirical formula:

[0076] The density of the aviation kerosene within the airport unit is calibrated every year. In front-line operations, the maintenance personnel are concerned about how many tons of oil need to be injected, and the total amount of fuel (volume) finally injected is displayed on the fuel truck dashboard after refueling. And the total amount of fuel (volume) to be injected by this equipment needs to be set before refueling. The density of aviation kerosene is between 0.775 - 0.840 kg / L, and in actual operations, it is only accurate to two decimal places. Therefore, there will inevitably be errors in the conversion between large mass and large volume.

[0077] Adopt this interval formula:

[0078] 1. Greatly improved fault tolerance

[0079] The precise formula is not adopted because the precise formula "locks" a point, but the actual variables fluctuate greatly (oil density, flow rate), making it difficult to exactly hit the target point. The interval formula allows a ±1-minute floating range before and after, greatly improving the system's tolerance to errors, delays, and jitters.

[0080] 2. Improved dynamic adaptability

[0081] The interval logic can dynamically judge the filling status according to the real-time flow rate and oil volume, while once the precise logic is preset incorrectly, it cannot correct itself. The "upper and lower limits" of the interval formula change with the real-time progress of the fuel, automatically adapting to the on-site situation of each aircraft and each refueling vehicle.

[0082] 3. Simplified system implementation and more stable control

[0083] Precise control often requires extremely stable flow rate, extremely fast response, and extremely few external disturbances. Once the conditions are not met, the control system is prone to errors. Using the empirical interval formula, the logic is simpler, the hardware requirements are lower, and the execution is more reliable. Between 3 and 5 minutes before the end of fuel filling, the injection of the bactericide is completed to ensure accurate dosage, uniform mixing, and timely injection.

[0084] 4. Improved risk mitigation ability

[0085] Through interval control, the injection of the bactericide is completed between 3 - 5 minutes before the end of refueling, neither too early for the agent to concentrate at the front end nor too late to be unable to be injected;

[0086] At the same time, this device realizes the full-process intelligent monitoring function:

[0087] 1. Initial refueling protection: When the fuel flow sensor 7 does not detect that the fuel has not entered the device, the solenoid valve 8 is in the closed state. This function ensures that the fuel flows into the pipeline before the bactericide.

[0088] 2. Real-time monitoring of fuel flow: The instantaneous fuel flow rate and the cumulative fuel input flow can be displayed on the intelligent digital display control unit 5.

[0089] 3. Real-time monitoring of bactericide dosage: The instantaneous flow rate of the bactericide and the remaining amount of the bactericide can be displayed on the intelligent digital display control unit 5.

[0090] 4. Refueling end warning: By feeding back the signal of the cumulative fuel input flow in the fuel flow sensor 7 to the intelligent digital display control unit 5 in real time, the intelligent digital display control unit 5 controls the electromagnetic diaphragm metering pump 9 to adjust the flow rate of the bactericide, ensuring that the bactericide is added before the end of fuel delivery, and voice prompts are given respectively after the addition of the bactericide and the end of fuel delivery.

[0091] 5. Automatic discharge of fuel and bactericide: After the fuel filling is completed, the drain valve 20 and the bactericide discharge valve 15 can be opened by operating the intelligent digital display control unit 5 to discharge the remaining fuel in the fuel pipeline 22 and the remaining bactericide in the bactericide distribution bin 3.

[0092] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
