Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 and Figure 4 An adjustable fuel additive mixer includes a mixing chamber 1, on which a horizontally arranged push cylinder 2 is fixedly connected. One end of the push cylinder 2 is located inside the mixing chamber 1, and the other end is located outside the mixing chamber 1. The mixing chamber 1 and the push cylinder 2 are made of transparent material to facilitate observation of the fuel or fuel additive inside the mixing chamber 1 and the push cylinder 2. The mixing chamber 1 is used to contain fuel, and the push cylinder 2 is used to contain fuel additive. A mixing pipe 3 is fixedly connected to one end of the push cylinder 2 inside the mixing chamber 1.

[0026] like Figure 1 and Figure 4 A circulation pump 4 is provided on one side of the mixing chamber 1. The circulation pump 4 is a prior art technology. The inlet of the circulation pump 4 is fixedly connected to an inlet pipe 5. One end of the inlet pipe 5 extends from the center of the bottom of the mixing chamber 1 into the interior of the mixing chamber 1. The outlet of the circulation pump 4 is fixedly connected to an outlet pipe 6. One end of the outlet pipe 6 extends into the interior of the mixing chamber 1 and is fixedly connected to a return pipe 7. One end of the return pipe 7 bends downward and is located exactly in the middle of the mixing chamber 1. One end of the mixing pipe 3 is fixedly connected to the return pipe 7. The radius of the return pipe 7 is larger than the radius of the outlet pipe 6, which allows the liquid inside the mixing pipe 3 and the outlet pipe 6 to flow more smoothly into the interior of the mixing chamber 1.

[0027] like Figure 1and Figure 4 The push cylinder 2 is movably connected to a movable plug 201 inside. The outside of the push cylinder 2 has a scale to facilitate observation of the fuel additive content inside the push cylinder 2. A movable push rod 202 is fixedly connected to the movable plug 201. One end of the movable push rod 202 passes through the push cylinder 2 and extends to the outside of the push cylinder 2. The mixing chamber 1 has an electric telescopic rod or a robotic arm as an external device that can push the movable push rod 202.

[0028] like Figure 1 , Figure 2 and Figure 4 An input pipe 8 is fixedly connected to the top of the push cylinder 2. A first electrically controlled valve 801 is installed on the input pipe 8 above the mixing chamber 1. A second electrically controlled valve 301 is installed on the mixing pipe 3. External fuel additives can be input into the interior of the push cylinder 2 through the input pipe 8. A connecting pipe 101 is provided at the top of the mixing chamber 1 to facilitate the input of external fuel into the interior of the mixing chamber 1 through the connecting pipe 101.

[0029] like Figure 1 and Figure 4 Inside the mixing chamber 1 and below the return pipe 7, there is a diversion platform 9. Multiple support shafts 10 are fixedly connected to the outer surface of the diversion platform 9. One end of the support shaft 10 is fixedly connected to the inner wall of the mixing chamber 1. The diversion platform 9 is a platform body that can disperse the fuel and fuel additives falling from above, so that the fuel and fuel additives can be better mixed. The fuel level inside the mixing chamber 1 does not exceed the horizontal plane where the bottom of the diversion platform 9 is located.

[0030] like Figure 1 and Figure 4 A support block 11 is fixedly connected between the top of the push cylinder 2 and the top of the inner wall of the mixing chamber 1. The support block 11 can provide auxiliary support for the push cylinder 2. A support ring 12 is fixedly connected to the outer surface of the mixing chamber 1. The support ring 12 is fixed to the external equipment to provide support for the mixing chamber 1.

[0031] like Figure 3 and Figure 4 The bottom of the mixing chamber 1 is fixedly connected to an output pipe 13, and a third solenoid valve 14 is installed on the output pipe 13. The first solenoid valve 801, the second solenoid valve 301 and the third solenoid valve 14 are all existing technologies, externally powered, and have corresponding control switches externally.

[0032] The working principle of the adjustable fuel additive mixer provided by this utility model is as follows:

[0033] When it is necessary to mix fuel additives and fuel, firstly, fuel is fed into the mixing chamber 1 and fuel additive is fed into the push cylinder 2. Then, the circulation pump 4 can be started to extract the bottom layer of fuel through the liquid inlet pipe 5, and then enter the return pipe 7 through the liquid outlet pipe 6. Finally, it is distributed to the surrounding area through the distribution platform 9 and finally dispersed back to the surface of the fuel.

[0034] Opening the second electronic control valve 301 pushes the movable push rod 202 to move the movable plug 201, allowing the fuel additive inside the push cylinder 2 to enter the return pipe 7 through the mixing pipe 3, and flow out together after being initially mixed with the fuel in the return pipe 7.

[0035] The second electronically controlled valve 301 opens multiple times, releasing only a portion of the fuel additive inside the push cylinder 2 each time, continuously adjusting the mixing ratio of the fuel additive. After each release of fuel additive, a portion of the mixed fuel and fuel additive sample is taken out through the output pipe 13 and tested using external testing equipment to select a better mixing ratio of fuel additive and fuel.

[0036] Compared with related technologies, the adjustable fuel additive mixer provided by this utility model has the following advantages:

[0037] This invention utilizes a circulating pump 4 to continuously extract fuel from the bottom of the mixing chamber 1 and circulate it to the top. This forcibly breaks down the natural stratification caused by the density difference between the fuel and additives, preventing unmixed areas from remaining during mixing. This achieves dynamic homogenization within the mixing chamber 1. Simultaneously, the circulating flow covers the entire vertical space of the mixing chamber 1, overcoming the problem of insufficient mixing at edges or corners caused by the limited coverage of the impeller during mixing.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
