Description

Technical Field

[0001] The utility model relates to the technical field of sterilization equipment, in particular to a mold spore killing device for a passenger aircraft fuel tank. Background Art

[0002] Corrosion of aircraft structures caused by secretions produced by microorganisms is called microbial corrosion. For aircraft structures, microbial corrosion mainly occurs in structural fuel tanks. The main factors affecting the reproduction of microorganisms in structural fuel tanks are mold spores, fuel, water and temperature. Aviation fuel is the main culture medium for mold.

[0003] Among the methods of sterilizing the fuel tank to control the microbial corrosion of the entire fuel tank, the most effective method is to use biocides. When the amount of mold spores inside the fuel tank is small, the fungicide is usually dissolved directly in the oil, and the mold is removed as the fuel burns; when the amount of mold spores inside the fuel tank is large, it is necessary to use a manual cleaning method for the fuel tank, that is, manually wearing a fungicide sprayer and drilling into the fuel tank through a manhole. However, the inventor of this method believes that there are the following defects; first, the caliber of the manhole of the aircraft fuel tank is small, and it is inconvenient to drill in and out of the manhole; second, most fungicides have a certain toxicity, and it is inevitable to be contaminated with fungicides when manually entering the closed aircraft fuel tank for spraying, thereby endangering the health of the operator.

[0008] The medicine feeding assembly comprises a booster water pump, a connecting pipe installed on one end of a rotating pipe located outside the oil tank, and a liquid inlet pipe and a liquid outlet pipe arranged on the liquid inlet end and the liquid outlet end of the booster water pump.

[0009] As a preferred solution of the utility model, a liquid storage tube is provided on one end of the rotating tube located inside the aircraft fuel tank, the atomizing nozzles are arranged in a circular array with the central axis of the rotating tube as the base point, and the water inlet end of the atomizing nozzle is penetrated by the inner cavity of the liquid storage tube, and the end of the liquid storage tube is in a closed state.

[0010] As a preferred solution of the utility model, a circular hole for the rotating tube to pass through is opened in the interior of the oil tank manhole blocking block, and a bearing matching with the outer ring of the rotating tube is arranged on the inner cavity side wall of the circular hole.

[0011] As a preferred solution of the utility model, a fixing plate is fixed on the side wall of the oil tank manhole blocking block, and the housing of the booster water pump is fixed on the side wall of the fixing plate by screws.

[0029] A fuel tank manhole blocking block 1 for blocking the manhole of an aircraft fuel tank, and a fungicide multi-angle spraying mechanism 2 arranged inside the fuel tank manhole blocking block 1;

[0030] The fungicide multi-angle spraying mechanism 2 includes a rotating tube 21, an atomizing nozzle 213 installed on one end of the rotating tube 21 located inside the oil tank, a rotating drive component installed on the outer ring of the rotating tube 21, and a drug feeding component fixed on the side wall of the oil tank manhole blocking block 1;

[0031] The rotary drive assembly includes a servo motor 211 mounted on the side wall of the oil tank manhole blocking block 1, a gear 210 mounted on the output shaft of the servo motor 211, and a gear ring 29 fixed on the outer ring side wall of the rotating tube 21 and meshing with the gear 210.

[0032] In specific use, after the servo motor 211 is powered on, the output shaft rotates the gear 210, and the meshing relationship between the gear 210 and the gear ring 29 causes the gear ring 29 to rotate, and the gear ring 29 causes the rotating tube 21 inserted into the oil tank to rotate through the traction effect, thereby causing the atomizing nozzle 213 for spraying the medicine at the end of the pipe to rotate, and the medicine is sprayed onto the inner wall of the oil tank by centrifugal force.

[0033] The medicine feeding assembly includes a booster water pump 24, a connecting pipe 27 installed on one end of the rotating tube 21 located outside the oil tank, and a liquid inlet pipe 25 and a liquid outlet pipe 26 arranged on the liquid inlet end and the liquid outlet end of the booster water pump 24.

[0034] A liquid storage pipe 212 is provided at one end of the rotating tube 21 located inside the aircraft fuel tank, and the atomizing nozzles 213 are arranged in a circular array with the central axis of the rotating tube 21 as the base point, and the water inlet end of the atomizing nozzle 213 is penetrated by the inner cavity of the liquid storage pipe 212, and the end of the liquid storage pipe 212 is in a closed state.

[0035] In specific use, in order to ensure that the agent is sprayed more evenly, the pressure of the booster pump 24 is used to spray the pressurized agent solution directly into the fuel tank, thereby solving the problem of manually drilling into the fuel tank during the killing of mold spores in the aircraft fuel tank.

[0036] A circular hole 3 is provided inside the tank manhole blocking block 1 for the rotating tube 21 to pass through, and a bearing 22 is provided on the inner cavity side wall of the circular hole 3 to match the outer ring of the rotating tube 21. The bearing 22 ensures that the rotating tube 21 rotates more smoothly.

[0039] Specifically, the gas-liquid slip ring 28 prevents the connecting tube 27 and the liquid outlet tube 6 that provide the rotating tube 21 with medicine from getting entangled during the rotation.

[0040] One end of the liquid outlet pipe 26 on the liquid outlet end of the booster water pump 24 extends through the interior of the connecting pipe 27 .

[0041] One end of the liquid inlet pipe 25 on the liquid inlet end of the booster water pump 24 is connected to a container containing a bactericide.
