Abstract
Description
Technical Field
[0001] This utility model belongs to the field of diesel deodorization technology, specifically a biodiesel deodorization device. Background Technology
[0002] With oil prices soaring and global concerns about fuel shortages, a surge in fuel-saving initiatives has emerged. Biodiesel, a new energy source supported by national policies, is a popular choice. However, it has a rotten, oily odor and requires deodorization to meet national standards. Biodiesel refers to fatty acid methyl or ethyl esters formed by esterifying vegetable oils (such as rapeseed oil, soybean oil, peanut oil, corn oil, and cottonseed oil), animal oils (such as fish oil, lard, tallow, and mutton fat), waste oils, or microbial oils with methanol or ethanol. Biodiesel is a typical "green energy" source, characterized by good environmental performance, excellent engine starting performance, good fuel efficiency, and a wide availability and renewable nature of its raw materials. Vigorously developing biodiesel is of significant strategic importance for sustainable economic development, promoting energy substitution, reducing environmental pressure, and controlling urban air pollution.
[0003] Existing biodiesel processing methods often involve deodorizing the biodiesel. A common method is to use a biodiesel deodorizer, which is then mixed with the biodiesel. This mixing process typically involves stirring, but existing stirring structures are generally unidirectional and fixed, resulting in inconsistent mixing uniformity and requiring long stirring times, leading to low mixing efficiency. To address these issues, a biodiesel deodorization device is proposed. Utility Model Content

Multiple stirring rods 4 are fixedly connected to the rotating rod 3 from top to bottom. A bracket 5 is fixedly installed at the bottom of the tank 1. A drive motor 6 is fixedly installed at the top of the bracket 5. The drive motor 6 is connected to the rotating rod 3 via an output shaft. A bevel gear 7 is fixedly installed at the upper part of the upper shaft tube 2. A vertical plate 8 is fixedly installed on the bracket 5. A rotating column 23 is rotatably installed on the vertical plate 8. A bevel gear 9 is fixedly connected to the rotating column 23 and connects to the bevel gear 7. A bevel gear 10 is fixedly installed at the upper part of the rotating rod 3, meshing with the bevel gear 9. Multiple upper connecting rods 11 are fixedly connected to the lower part of the upper shaft tube 2. Multiple stirring rods 4 are fixedly connected to the upper connecting rods 11. A vertical fixed rod 12 is fixedly connected from top to bottom to multiple stirring rods 13. The stirring rods 13 and 4 are arranged crosswise. In this structure, the stirring rods 4 on the rotating rod 3 are driven by the drive motor 6 to rotate and stir the biodiesel and deodorant. When the rotating rod 3 rotates, it drives the bevel gear 10 to rotate. The bevel gear 10 drives the bevel gear 7 to rotate through the bevel gear 9, thereby driving the upper shaft tube 2 to rotate in the opposite direction to the rotating rod 3. At this time, the upper shaft tube 2 drives the vertical fixed rod 12 on the upper connecting rod 11 to rotate, thereby driving the stirring rods 13 to rotate. At this time, the stirring rods 13 and 4 rotate in opposite directions, thereby continuously shearing the biodiesel and deodorant mixture while stirring, thereby improving the uniformity of the mixing of biodiesel and deodorant and improving the mixing efficiency.
[0020] refer to Figures 1 to 3 As shown, a lower connecting rod 14 is fixedly connected to the bottom end of the vertical fixed rod 12, and a lower shaft tube 15 is fixedly connected to one end of the lower connecting rod 14. The lower shaft tube 15 is rotatably connected to the rotating rod 3 through a bearing. In this structure, the lower end of the vertical fixed rod 12 is connected to the lower shaft tube 15 through the lower connecting rod 14, thereby supporting the lower part of the vertical fixed rod 12 and ensuring the rotational stability of the vertical fixed rod 12.
[0021] refer to Figures 1 to 3 As shown, the lower part of the rotating rod 3 is rotatably connected to the support shaft seat 16 via a bearing. The support shaft seat 16 is fixedly connected to the surrounding area of the inclined rod 17. The bottom end of the inclined rod 17 is fixedly installed at the bottom of the inner cavity of the tank body 1. In this structure, the support shaft seat 16 and the inclined rod 17 support the lower part of the rotating rod 3, thereby ensuring the stable rotation of the rotating rod 3.
[0022] refer to Figures 1 to 3 As shown, multiple support legs 18 are fixedly connected to the bottom of the tank body 1, and the support legs 18 are used to support the tank body 1 in this structure.
[0023] refer to Figures 1 to 3As shown, a biodiesel feed pipe 19 is fixedly connected to the top of the tank body 1 and communicates with the inner cavity of the tank body 1. In this structure, the feed pipe 19 facilitates the feeding of biodiesel into the tank body 1.
[0024] refer to Figures 1 to 3 As shown, a deodorant feeding pipe 20 that communicates with the inner cavity of the tank 1 is fixedly connected to the top of the tank 1. In this structure, the deodorant is fed into the tank 1 using the feeding pipe 20.
[0025] refer to Figures 1 to 3 As shown, a discharge pipe 21 communicating with the inner cavity of the tank 1 is fixedly connected to the bottom of the tank body 1. A valve 22 is installed on the discharge pipe 21. In this structure, the discharge pipe 21 discharges biodiesel from the tank body 1, and the valve 22 can control the opening and closing of the discharge pipe 21.
[0026] The implementation principle of a biodiesel deodorization device according to an embodiment of this application is as follows: In use, biodiesel is fed into tank 1 through feed pipe 19, and then a corresponding amount of deodorant is fed into tank 1 through feed pipe 20. Then, the drive motor 6 drives the stirring rod 4 on the rotating rod 3 to rotate and stir the biodiesel and deodorant. When the rotating rod 3 rotates, it drives the bevel gear 10 to rotate. The bevel gear 10 drives the bevel gear 7 to rotate through bevel gear 9, thereby driving the upper shaft tube 2 to rotate in the opposite direction to the rotating rod 3. At this time, the upper shaft tube 2 drives the vertical fixed rod 12 on the upper connecting rod 11 to rotate, thereby driving the stirring rod 13 to rotate. At this time, the stirring rod 13 and the stirring rod 4 rotate in opposite directions, thereby continuously shearing the mixture of biodiesel and deodorant while stirring, thereby improving the uniformity of the mixture of biodiesel and deodorant and improving the mixing efficiency. After deodorization is completed, the valve 22 is opened, thereby allowing the biodiesel to be discharged from tank 1.
