Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4This utility model provides a technical solution: a rapeseed oil degreasing device for rapeseed oil production, comprising a rapeseed oil degreasing tank 1 and a rotating outer ring 11. A fixed motor 2 is installed in the middle of the upper end of the rapeseed oil degreasing tank 1. A bearing is embedded in the middle of the upper end of the rapeseed oil degreasing tank 1, and the shaft end of the fixed motor 2 passes through the bearing and is connected to a rotating shaft 3. A spur gear 5 is horizontally fixed to the outside of the rotating shaft 3. Multiple centrifugal blades 4 are longitudinally welded to the lower end of the rotating shaft 3. Mounting brackets 6 are longitudinally fixed around the upper end of the rapeseed oil degreasing tank 1 by bolts. Electric push rods 7 are longitudinally fixed inside each of the multiple mounting brackets 6. The upper end of the rapeseed oil degreasing tank 1 is suspended. There is a fixed connecting plate 8, and a stepped annular rail 9 is installed on the upper end of the fixed connecting plate 8. An annular slide rail 10 is slidably installed on the upper end of the stepped annular rail 9. A rotating outer ring 11 is slidably located above the annular slide rail 10. A rotating inner plate 12 is welded to the inner side of the rotating outer ring 11. An annular straight tooth 13 is fixed inside the rotating inner plate 12. Multiple connecting rods 17 are horizontally welded to the outer side of the rotating inner plate 12. An arc-shaped scraping blade 18 is welded to the other end of each of the multiple connecting rods 17. This design solves the problem that the scraper size in the original device is small, and it is necessary to scrape the inner wall of the oil drum circle by circle to scrape the entire drum wall clean, resulting in low scraping efficiency and affecting subsequent work.

[0020] As the first embodiment of this utility model: a discharge pipe 14 is welded to the lower end of the rapeseed oil defatting tank 1. The lower end of the discharge pipe 14 is connected to an oil collection pipe 15 and an oil sludge collection pipe 16 via flanges and bolts. Valves are installed on the outside of both the oil collection pipe 15 and the oil sludge collection pipe 16. The added oil collection pipe 15 facilitates the collection of oil in the rapeseed oil defatting tank 1, and the oil sludge collection pipe 16 facilitates the collection of oil sludge in the rapeseed oil defatting tank 1. The movable ends of multiple electric push rods 7 are fixed to the fixed connecting plate 8 via flanges and bolts. By adding multiple electric push rods 7 and fixing their movable ends to the fixed connecting plate 8 via flanges and bolts, the fixed connecting plate 8 can be moved when the movable ends of the multiple electric push rods 7 extend or retract synchronously.

[0021] The rotating inner disk 12 is slidably sleeved outside the rotating shaft 3. The annular spur teeth 13 are positioned above the spur gear 5, and the specifications of the annular spur teeth 13 match those of the spur gear 5. Because the added annular spur teeth 13 are positioned above the spur gear 5 and their specifications match those of the spur gear 5, when the annular spur teeth 13 move down and are sleeved outside the spur gear 5, they can be driven to rotate and mesh with it. Multiple arc-shaped scraping blades 18 slide against the inner wall of the rapeseed oil degreasing tank 1. The rotation of these multiple arc-shaped scraping blades 18 quickly scrapes away the sludge from the inner wall of the rapeseed oil degreasing tank 1.

[0022] As a second embodiment of this utility model: Starting the fixed motor 2 drives the rotating shaft 3, spur gear 5, and multiple centrifugal blades 4 to rotate, thus rotating and degreasing the rapeseed oil inside the rapeseed oil degreasing tank 1. Opening the valve at the oil collection pipe 15 allows the rapeseed oil inside the degreasing tank 1 to be discharged. When it is necessary to scrape off the sludge from the inner wall of the rapeseed oil degreasing tank 1, the movable ends of multiple electric push rods 7 are controlled to move downwards synchronously, causing the fixed connecting plate 8 to move horizontally downwards. This causes the stepped annular rail 9 and the annular slide rail 10 to move downwards as well, and the rotating outer ring 11 and the rotating inner plate 12 placed above to move downwards as well. Multiple connecting rods 17 and multiple arc-shaped scraping blades 18 also move downwards accordingly. The material is moved downwards until the multiple arc-shaped scraping blades 18 are completely in contact with the inner wall of the rapeseed oil degreasing tank 1. At this time, the annular straight teeth 13 are sleeved on the outside of the spur gear 5 and mesh with it. The fixed motor 2 is started again. The fixed motor 2 drives the rotating shaft 3, the spur gear 5 and multiple centrifugal blades 4 to rotate. The annular straight teeth 13 will also mesh with and rotate with it. The rotating inner disk 12 drives the rotating outer ring 11 to rotate on the stepped annular rail 9, thereby causing the multiple connecting bars 17 and multiple arc-shaped scraping blades 18 to rotate. The rotating multiple arc-shaped scraping blades 18 can quickly scrape off the oil sludge on the inner wall of the rapeseed oil degreasing tank 1. Then, the oil collection pipe 15 is closed and the oil sludge collection pipe 16 is opened to discharge the scraped oil sludge. All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
