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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-8 As shown in the figure, this utility model embodiment provides a high-efficiency mixing device for the production of fatty acid methyl esters, including an outer shell 1, an upper cover 2 on the outer shell 1, a base 3 at the lower end of the outer shell 1, a mixing motor 4 on the upper cover 2, a feed inlet 5 on the upper cover 2, a rotating shaft 6 fixedly connected to the output end of the mixing motor 4, the lower end of the rotating shaft 6 being rotatably connected to the base 3, a sleeve 7 sleeved on the outer side of the rotating shaft 6, the sleeve 7 being connected to the rotating shaft 6 through an adjustment unit, and multiple sets of circumferentially arrayed stirring blades 8 fixedly connected to the side of the sleeve 7, the stirring blades 8 being provided with a scraping unit for scraping the sidewalls.

[0026] The outer side of the rotating shaft 6 is provided with a guide protrusion 9, the sleeve 7 is sleeved on the outer side of the guide protrusion 9, and the stirring blade 8 is provided with a plurality of arrayed flow holes 10.

[0027] In actual use, the raw materials to be mixed are input through the feed inlet 5. The mixing motor 4 rotates, which drives the rotating shaft 6 to rotate, which in turn drives the stirring blade 8 to mix the raw materials in the outer shell 1. The adjustment unit and the scraping unit can scrape off the raw materials adhering to the inner wall of the outer shell 1. After scraping, they can be mixed with the raw materials already in the outer shell 1 to ensure the uniformity of mixing and to ensure that the raw materials can be fully utilized.

[0028] Combination Figure 6 , Figure 7 and Figure 8 The adjusting unit includes a first connecting plate 11 fixedly connected to the sleeve 7, the rotating shaft 6 passing through the first connecting plate 11, a first connecting ring 12 at the lower end of the upper cover 2, a first annular snap-fit ​​protrusion 13 fixedly connected to the upper end of the first connecting ring 12, a first annular snap-fit ​​groove 14 that mates with the first annular snap-fit ​​protrusion 13 on the upper cover 2, and the first connecting ring 12 and the first connecting plate 11 are connected by a first spring 15 for providing elasticity.

[0029] The upper end of the first connecting plate 11 is fixedly connected to a plurality of first connecting rods 16 arranged in a circular array, the lower end of the upper cover 2 is fixedly connected to a first hemispherical protrusion 17, and the upper end of the first connecting rod 16 is provided with a first curved surface 18 that cooperates with the first hemispherical protrusion 17.

[0030] When the aforementioned adjustment unit is actually in use, when the rotating shaft 6 rotates, the first connecting rod 16 connected to the first connecting plate 11 also rotates. When the first connecting rod 16 rotates to contact the first hemispherical protrusion 17, it stretches the first spring 15 and drives the sleeve 7 to move downward. When the first connecting rod 16 disengages from the first hemispherical protrusion 17, the sleeve 7 returns to its original position under the elastic force of the first spring 15, which can drive the sleeve 7 to move in the up and down direction.

[0031] The scraping unit includes a movable block 19 disposed within the stirring blade 8. A scraper 20 is fixedly connected to the side of the movable block 19. A movable rod 21 is fixedly connected to the inward side of the movable block 19. A symmetrically arranged guide groove 22 is provided inside the stirring blade 8. A guide rod 23 is fixedly connected inside the guide groove 22. A symmetrically arranged guide plate 24 is fixedly connected to the side wall of the movable rod 21. The guide rod 23 passes through the guide plate 24. The side of the guide plate 24 is connected to the side wall of the guide groove 22 through a second spring 25 for providing elasticity.

[0032] The lower end of the upper cover 2 is provided with a second connecting ring 26, and the upper end of the second connecting ring 26 is fixedly connected with a second annular snap-fit ​​protrusion 27. The upper cover 2 is provided with a second annular snap-fit ​​groove 28 that cooperates with the second annular snap-fit ​​protrusion 27. The lower end of the second connecting ring 26 is fixedly connected with a plurality of second connecting rods 29 arranged in a circumferential array. Each second connecting rod 29 passes through each set of stirring blades 8. The side of the second connecting rod 29 is fixedly connected with a plurality of sets of second hemispherical protrusions 30. The end of the moving rod 21 is provided with a second curved surface 31 that cooperates with the second hemispherical protrusions 30.

[0033] When the above-mentioned scraping unit is actually used, when the sleeve 7 moves up and down, it drives the stirring blade 8 to move up and down as well. The second connecting rod 29 and the second hemispherical protrusion 30 set on it will not move up and down. When the guide rod 23 contacts the second hemispherical protrusion 30, it compresses the second spring 25 and drives the moving block 19 and the scraper 20 to extend out of the stirring blade 8 to scrape the raw material on the inner wall of the outer shell 1. When the guide rod 23 disengages from the second hemispherical protrusion 30, under the elastic force of the second spring 25, the scraper 20 returns to its original position, waiting for the next scraping operation on the inner wall of the outer shell 1.

[0034] Combination Figure 3 and Figure 4 The base 3 is provided with a plurality of circumferentially arranged elastic balls 32. A rotating rod 33 is fixedly connected to the side of the rotating shaft 6. An air passage 34 that cooperates with the elastic balls 32 is provided inside the base 3.

A one-way air inlet valve 36 is also provided on the base.

[0035] When the rotating shaft 6 rotates, it drives the rotating rod 33 to rotate. The rotating rod 33 compresses the elastic ball 32 and outputs gas through the air passage 34 and the one-way air outlet valve 35. The gas turns into bubbles in the raw material, causing the raw material to surge, which can improve the mixing efficiency and make the raw material more uniformly mixed. When the elastic ball 32 returns to its original shape, air is introduced through the one-way air inlet valve 36.

[0036] In summary, the working principle of this utility model is as follows: Raw materials to be mixed are input through the feed inlet 5. The mixing motor 4 rotates, driving the rotating shaft 6 to rotate, which in turn drives the stirring blade 8 to mix the raw materials inside the outer shell 1. The adjustment unit and scraping unit can scrape off the raw materials adhering to the inner wall of the outer shell 1. After scraping, the raw materials can be mixed with the existing raw materials inside the outer shell 1, ensuring uniform mixing and full utilization of the raw materials. When the rotating shaft 6 rotates, the first connecting rod 16 connected to the first connecting plate 11 also rotates. When the first connecting rod 16 rotates to contact the first hemispherical protrusion 17, it stretches the first spring 15 and drives the sleeve 7 downward. When the first connecting rod 16 disengages from the first hemispherical protrusion 17, under the elastic force of the first spring 15, the sleeve 7 returns to its original position, enabling the sleeve 7 to move up and down. The sleeve 7 moves up and down, causing the stirring blade 8 to move up and down as well. The second connecting rod 29 and the second hemispherical protrusion 30 on it do not move up and down. When the moving rod 21 contacts the second hemispherical protrusion 30, it compresses the second spring 25 and causes the moving block 19 and the scraper 20 to extend out of the stirring blade 8 to scrape the raw material on the inner wall of the outer shell 1. When the moving rod 21 disengages from the second hemispherical protrusion 30, the scraper 20 returns to its original position under the elastic force of the second spring 25, waiting for the next scraping operation on the inner wall of the outer shell 1. When the rotating shaft 6 rotates, it causes the rotating rod 33 to rotate. The rotating rod 33 compresses the elastic ball 32 and outputs gas through the air passage 34 and the one-way air outlet valve 35. The gas turns into bubbles in the raw material, causing the raw material to surge, which can improve the mixing efficiency and make the raw material mixed more evenly.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
