The drive shaft has a drive positioning ring fixedly connected to its top outer wall, and there are two drive positioning rings in total. The turntable is located between two drive positioning rings.
[0009] By adopting the above technical solution, the drive shaft and multiple driven shafts are limited.
[0010] As a further description of the above technical solution:
[0011] A sealing gasket is provided between the top of the drying tank and the top cover, and the top cover is fixedly connected to the top of the drying tank by fixing bolts.
[0012] By adopting the above technical solutions, the airtightness of the drying tank is improved.
[0013] As a further description of the above technical solution:
[0014] A support plate is fixedly connected to the outer wall of the drying tank, a vacuum pump is fixedly connected to the top of the support plate, and an air extraction pipe is fixedly connected to the left side of the vacuum pump, extending into the interior of the drying tank.

[0022] By employing the above technical solution, the crude fish oil vacuum drying device of this utility model has at least the following beneficial effects:
[0023] Compared with existing technologies, this crude fish oil vacuum drying device, during fish oil drying, uses a motor to drive the drive shaft and stirring blades to rotate. Because the stirring blades are arc-shaped plates, the fish oil in the center is diffused outwards. The rotation of the drive shaft also drives a turntable and multiple driven gears and driven shafts within it to rotate synchronously. Since the driven gears mesh with fixed gears, the multiple driven shafts, driven gears, and spiral blades revolve around the drive shaft while simultaneously rotating on their own axes. This allows the fish oil inside to be carried from the inside to the top, shortening the drying time and improving drying efficiency. Simultaneously, multiple connecting plates and scrapers connected to the drive shaft rotate synchronously with the drive shaft, scraping off fish oil adhering to the inner wall of the drying tank, preventing long-term adhesion and difficulty in cleaning, and facilitating mixing with the next batch of fish oil to maintain overall quality.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.
[0035] Reference Figure 1-8 This utility model provides a vacuum drying device for crude fish oil, comprising a drying tank 1, a top cover 2 on the top of the drying tank 1, a motor 3 fixedly connected to the top of the top cover 2, a drive shaft 4 fixedly connected to the output end of the motor 3, stirring blades 5 fixedly connected to the outer wall of the drive shaft 4, and multiple stirring blades 5, each of which is an arc-shaped plate, a turntable 6 fixedly connected to the outer wall of the drive shaft 4, and driven shafts 7 installed inside the turntable 6, also multiple driven shafts 7, each driven shaft 7 having a driven gear 8 fixedly connected to its top, and spiral blades 9 provided on the outer wall of each driven shaft 7, and a fixed gear 10 fixedly connected to the bottom of the top cover 2, the outer walls of the driven gears 8 meshing with the outer walls of the fixed gear 10. During fish oil drying, the motor 3 drives the drive shaft 4 and stirring blades 5 to rotate, and because the stirring blades 5 are arc-shaped plates, the fish oil located in the center diffuses to the surrounding area. The rotation of the drive shaft 4 further... The rotating disc 6, along with its multiple driven gears 8 and driven shafts 7, rotates synchronously. Since the multiple driven gears 8 mesh with the fixed gear 10, the multiple driven shafts 7, driven gears 8, and spiral blades 9 revolve around the drive shaft 4 while also rotating on their own axis around the driven shaft 7. This allows the fish oil inside to be carried from the inside to the top, shortening the drying time. The outer wall of the drive shaft 4 is fixedly connected to a connecting plate 11, and there are multiple connecting plates 11. All connecting plates 11 are located at the bottom of the outer wall of the drive shaft 4, and the top of each connecting plate 11 is fixedly connected to a scraper 12. The top of the scraper 12 is fixedly connected to the bottom of the rotating disc 6. At the same time, the multiple connecting plates 11 and scrapers 12 connected to the drive shaft 4 rotate synchronously with the drive shaft 4, which can scrape off the fish oil adhering to the inner wall of the drying tank 1, preventing it from adhering for a long time and being difficult to clean, making it easier to mix with the next batch of fish oil and affecting the overall quality.
[0036] Each of the top outer walls of multiple driven shafts 7 is fixedly connected with a driven positioning ring 13, and there are two driven positioning rings 13 in total. The turntable 6 is located in the middle of two adjacent driven positioning rings 13. The top outer wall of the drive shaft 4 is fixedly connected with a drive positioning ring 14, and there are two drive positioning rings 14 in total. The turntable 6 is located in the middle of two drive positioning rings 14, so that the drive shaft 4 and multiple driven shafts 7 are limited when they rotate.
[0037] A sealing gasket 15 is provided between the top of the drying tank 1 and the top cover 2 to improve the airtightness of the drying tank 1. The top cover 2 is fixedly connected to the top of the drying tank 1 by fixing bolts 16.
[0038] A support plate 17 is fixedly connected to the outer wall of the drying tank 1. A vacuum pump 18 is fixedly connected to the top of the support plate 17. A suction pipe 19 is fixedly connected to the left side of the vacuum pump 18. The suction pipe 19 extends into the interior of the drying tank 1. The vacuum pump 18 operates to provide a vacuum environment inside the drying tank 1.
[0039] A feed pipe 20 is fixedly connected to the left outer wall of the drying tank 1. A cap 21 is threadedly connected to the top of the feed pipe 20. A discharge port 22 is opened at the bottom of the drying tank 1. A discharge pipe 23 is fixedly connected to the bottom of the drying tank 1. A solenoid valve 24 is installed on the top of the outer wall of the discharge pipe 23.
[0040] The drying tank 1 has an inner layer 25 on its outer wall, and a heating wire 26 is installed inside the inner layer 25. There are multiple heating wires 26. The bottom of the drying tank 1 is fixedly connected to a support leg 27. There are multiple support legs 27.
[0041] Working principle: Fish oil enters the inner wall of the drying tank 1 through the feed pipe 20. Then, the top of the feed pipe 20 is sealed with the cover 21. At the same time, multiple heating wires 26 work. Finally, the motor 3 drives the drive shaft 4 and the stirring blade 5 to rotate. Since the stirring blade 5 is an arc plate, it spreads the fish oil in the middle to the surrounding area. When the drive shaft 4 rotates, it drives the turntable 6 and multiple driven gears 8 and driven shafts 7 in the turntable 6 to rotate synchronously. Since multiple driven gears 8 are meshed with the fixed gear 10, multiple driven shafts 7, driven gears 8 and spiral blades 9 can rotate around the drive shaft 4 while also rotating on their own axis around the center of the driven shaft 7. This allows the fish oil in the middle to be carried from the inside to the top, shortening the drying time and improving the drying efficiency. At the same time, multiple connecting plates 11 and scrapers 12 connected to the drive shaft 4 rotate synchronously with the drive shaft 4, which can scrape off the fish oil adhering to the inner wall of the drying tank 1, preventing it from adhering for a long time and being difficult to clean.
