Description

Technical Field

[0001] The utility model relates to the technical field of aviation fuel processing, in particular to a high-efficiency stirring device for aviation fuel oil. Background Art

[0002] Aviation, a complex and strategically significant human activity, generally refers to the flight (navigation) of aircraft within the Earth's atmosphere (airspace). Common examples include civil airliners transporting aircraft and military aircraft cruising. Both civil and military aircraft require aviation fuel for power generation. As a fuel specifically designed for aircraft, aviation fuel is of higher quality than the fuel used in heating systems and cars, and typically contains various additives to reduce the risk of freezing and explosion due to high temperatures.

[0003] The prerequisite for the good use of multiple additives is to ensure that the additives are fully mixed with the fuel oil. However, the stirring devices used in the existing production process are still mainly based on a single mechanical strong stirring operation mode. Although this can theoretically meet the use effect, in reality, the stirring method and stirring direction are fixed, resulting in poor uniformity. Utility Model Content

[0026] Working principle:

[0027] Example 1

[0028] The fuel oil to be processed is delivered to the inside of the mixing tank 1 through the main feeding pipe 4. After completion, the sealing cover is connected to the external thread of the open port of the main feeding pipe 4. Then, the additive is placed inside the auxiliary feeding valve pipe 5. Then, the water pump body 101 inside the pumping assembly 10 is started first. The water pump body 101 delivers the fuel oil in the bottom of the mixing tank 1 to the annular pipe 91 inside the reflux pipe 9 through the liquid delivery pipe 102 and the diversion valve pipe 103. Then, it is expanded into a multi-strand linear flow through multiple diversion pipe heads 92, and the diversion pipe heads 92 deliver the fuel oil. The specific height of the feed must not exceed the bottom structure of the distribution plate 8. When the pumping component 10 is pumping, the valve inside the auxiliary feeding valve pipe 5 and the first servo motor 7 are opened. The additive inside the auxiliary feeding valve pipe 5 first flows down to the surface of the distribution plate 8. With the output of the first servo motor 7, the output end of the first servo motor 7 will drive the distribution plate 8 and the first stirring component 6 to rotate synchronously. The rotating distribution plate 8 will centrifugally expand the additive, so that the additive is fully in contact with the multiple strands of fuel oil, thereby achieving one-time stirring in disguised form.

[0029] When the fuel oil containing additives flows down, the first servo motor 7 maintains continuous output, and then the first stirring component 6 stirs the fuel oil containing additives again to further ensure the uniformity of the fuel oil containing additives. After processing is completed, it can be output and collected through the discharge valve pipe 3.

[0030] Example 2

[0031] The fuel oil to be processed is transported to the interior of the mixing box 1 through the main feeding pipe 4. After completion, the sealing cover is connected to the external thread of the open port of the main feeding pipe 4. Then, the additive is placed in the interior of the auxiliary feeding valve pipe 5. The valve inside the auxiliary feeding valve pipe 5 and the first servo motor 7 are opened. The additive inside the auxiliary feeding valve pipe 5 first flows down to the surface of the distribution plate 8. With the output of the first servo motor 7, the output end of the first servo motor 7 will drive the distribution plate 8 and the first stirring component 6 to rotate synchronously. The rotating distribution plate 8 will centrifugally expand the additive to make the additive uniformly dispersed.

[0032] Then, the first servo motor 7 maintains continuous output, and then the first stirring component 6 fully stirs the fuel oil containing additives. In order to further ensure the uniformity of the fuel oil containing additives, the auxiliary stirring component 122 inside the side stirring device 12 can be started, so that the auxiliary stirring component 122 drives the second servo motor 121 to stir and shear the fuel oil in the bottom of the stirring box 1 in an inclined direction. After the processing is completed, it can be output and collected through the discharge valve pipe 3.
