Abstract
Description
Technical Field
[0001] This utility model relates to the field of alcohol-based fuel blending technology, specifically to an alcohol-based biofuel additive blending and mixing device. Background Technology
[0002] Alcohol-based biofuels are a new type of alternative fuel energy composed mainly of alcohols. They have advantages such as being renewable, environmentally friendly, and economically comparable, and are widely used in catering, industry and other fields. They mainly exist in liquid or solid form, and due to the characteristics of biomass energy, they are regarded as an environmentally friendly and clean energy source.
[0003] The principle of the alcohol-based biofuel additive blending and mixing device is mainly based on the principle of mechanical stirring and dispersion mixing. Through specific structures and components, the additive and alcohol-based fuel are uniformly mixed, which optimizes the combustion performance of the fuel and improves the combustion efficiency, improves the combustion speed and combustion stability of the fuel, and makes the fuel burn more completely, thereby improving the calorific value and combustion efficiency.
[0004] Existing alcohol-based biofuel additive blending and mixing devices often involve directly pouring various fuel additives into the mixing tank during the blending process. This results in insufficient mixing of alcohol-based biofuel additives with different chemical properties due to the rapid feeding. Furthermore, the large amount of alcohol-based biofuel additives falling together causes accumulation, prolonging the mixing time and reducing the mixing efficiency of the alcohol-based biofuel additive blending device. At the same time, existing alcohol-based biofuel additive blending and mixing devices often cause sedimentation and adsorption on the inner wall of the tank over time, which not only affects the mixing quality of alcohol-based liquid fuels but also leads to the waste of raw materials.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0025] The present invention will be further described below with reference to the embodiments.
[0026] Example 1
[0027] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a mixing device for alcohol-based biofuel additives. It includes a mixing tank 1, with two symmetrically installed slowing boxes 2 on the upper end of the mixing tank 1. A conical inlet 3 is fixedly installed on the upper end of the slowing box 2. Square grooves 4 are opened in pairs opposite each other on the inner side of the slowing box 2. Irregularly shaped sliding blocks 5 are slidably installed on the inner side of the square grooves 4. A buffer plate 6 is rotatably installed on one side of each irregularly shaped sliding block 5. A buffer spring 7 is fixedly installed on the inner side of the square grooves 4 near the lower end of the irregularly shaped sliding block 5. A return spring 8 is fixedly installed on one side of the lower end of the buffer plate 6.
[0028] A movable shaft 9 is installed through the connection between the irregular sliding block 5 and the buffer plate 6. A rotating shaft 10 is installed through the center of the inner side of the conical feed inlet 3. Several material distribution plates 11 are installed at equal intervals on the outer side wall of the rotating shaft 10. Rolling bearings 16 are fixedly installed at the center of the upper and lower ends of the square support block 13. Cylindrical support rods 17 are rotatably installed on the inner side of the rolling bearings 16. Several mixing and stirring blades 18 are installed at equal intervals on the outer side wall of the cylindrical support rods 17. A rotating motor 19 is fixedly installed at the center of the upper end of the mixing tank 1. A rotating shaft 12 is connected to the output end of the rotating motor 19. A discharge port 20 is installed at the center of the lower end of the mixing tank 1.
[0029] When the alcohol-based biofuel additive mixing device is in use, the alcohol-based biofuel additives to be mixed are added sequentially through the conical inlet 3. After entering the conical inlet 3, the drive motor set on one side of the conical inlet 3 is started simultaneously, so that the rotating shaft 10 rotates under the drive of the drive motor, thereby driving the distribution plate 11 to evenly distribute the alcohol-based biofuel additives poured in from the conical inlet 3, so that the alcohol-based biofuel additives can be evenly distributed into the two symmetrical slow-speed boxes 2.
[0030] In the instant the alcohol-based biofuel additive is distributed to the two symmetrical slow-down boxes 2, it first impacts the buffer plate 6 for initial deceleration and mixing. At the same time, the impact force drives the irregular sliding block 5 to press down the buffer spring 7. Under the elastic action of the buffer spring 7, the alcohol-based biofuel additive is further decelerated, so that the alcohol-based biofuel additive falls into the interior of the mixing tank 1 at an appropriate speed. This effectively avoids the situation where alcohol-based biofuel additives with different chemical properties are not fully mixed due to excessive feeding, thereby improving the mixing efficiency of the alcohol-based biofuel additive mixing device. After all the alcohol-based biofuel additives have fallen in, the buffer plate 6 can be quickly reset by the reset spring 8 in conjunction with the movable shaft 9.
[0031] Once all the alcohol-based biofuel additives are poured into the mixing tank 1, the rotating motor 19 is simultaneously started. Driven by the rotating motor 19, the rotating shaft 12 rotates, which in turn rotates the square support block 13, which in turn rotates the mixing and stirring blades 18. Under the centrifugal force of the rotation and the action of the rolling bearing 16, the cylindrical support rod 17 rotates synchronously, making the alcohol-based biofuel additives more evenly mixed. Finally, the mixed alcohol-based biofuel additives are transported to the outside of the mixing tank 1 through the discharge port 20.
[0032] Example 2
[0033] Reference Figure 1-4 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a rotating shaft 12 is installed through the center of the mixing tank 1, and several square support blocks 13 are fixedly installed at equal intervals at the center of the outer side wall of the rotating shaft 12. A cleaning mounting seat 14 is fixedly installed on one side of each square support block 13, and a cleaning scraper 15 is fixedly installed at the center of one side of each cleaning mounting seat 14.
[0034] When the alcohol-based biofuel additive blending device is used for blending, the alcohol-based biofuel additive in the blending tank 1 is driven by the rotating shaft 12 to make the square support block 13 rotate evenly, thereby causing the cleaning mounting seat 14 to rotate synchronously. This allows the cleaning scraper 15, which is in close contact with the inner wall of the blending tank 1, to promptly scrape off the alcohol-based biofuel additive that has settled or adsorbed on the inner wall of the blending tank 1. This avoids affecting the mixing quality of the alcohol-based liquid fuel due to excessive adsorption inside the blending tank 1, and further saves production costs.
[0035] The remaining structure is the same as that in Example 1.
[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
