Description

Technical Field

[0001] The utility model relates to the technical field of scraping devices, in particular to a scraping device for a centrifuge used in fish oil processing. Background Art

[0002] Unsaturated fatty acids essential for the human body generally cannot be synthesized by itself, and fish oil is an unsaturated fatty acid component extracted from deep-sea fish bodies, with high nutritional value. Therefore, people's demand for fish oil is increasing. After the fish body is steamed and broken, a centrifuge is needed to separate the bones, meat and oil, so as to initially extract crude oil. The centrifuge mainly includes a drum and a motor for driving the drum to rotate. A filter bag is attached to the inner wall of the drum, and filter holes are provided on the inner wall of the drum for the liquid-phase fish oil to be thrown out; during the separation process, a large amount of solid-phase bones and meat will adhere to the inner wall of the drum and continuously deposit to form a filter cake, reducing the separation effect. Therefore, a centrifuge for oil extraction generally also uses a scraper to continuously scrape off the solid-phase material and discharge it through the discharge port at the bottom of the drum.

[0003] When the existing scraping device of the centrifuge is in use, it mainly relies on the scraper to scrape off the fish meat on the drum. When the scraper is in use, the scraper needs to be connected to the driving rod. At present, the scraper and the driving rod are integrally formed by welding. In this way, when the scraper is damaged, it is not convenient to replace the scraper, thus affecting the work efficiency. Therefore, a scraping device for a centrifuge used in fish oil processing needs to be designed. Summary of the Utility Model

[0026] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments to facilitate understanding of the content of the present utility model. The methods used in the present utility model are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products unless otherwise specified.

[0027] Refer to Figures 1-5 A scraping device for a centrifuge used in fish oil processing provided by the present utility model includes a centrifuge body 1. An elevating mechanism and a driving mechanism are arranged at the upper end of the centrifuge body 1. A connecting component is arranged at the lower end of the driving mechanism. A scraper 16 is arranged inside the centrifuge body 1. The driving mechanism is connected to the scraper 16 through the connecting component.

[0028] Specifically, during scraping, with the cooperation of the connecting component, the driving mechanism drives the scraper 16 to approach the inner wall of the drum. After the scraper 16 contacts the filter cake, then with the rotation of the drum, the inner wall of the drum can be scraped under the cooperation of the scraper 16. Then the elevating mechanism works to drive the scraper 16 to move up and down, so that the inner wall of the drum can be scraped comprehensively, which is beneficial to the processing of fish oil. When the scraper 16 needs to be replaced, the fixing of the scraper 16 is released by using the connecting component, so that it is convenient to replace the new scraper 16, thereby improving the replacement efficiency of the scraper 16.

[0029] Specifically, the driving mechanism includes a transmission shaft 6, a hydraulic telescopic rod 7, a transmission rod 8, a sliding hole 9, a sliding rod 10, a rotating cylinder 11 and a bearing seat 12. The upper end of the centrifuge body 1 is fixedly connected with a hydraulic telescopic rod 7 and a bearing seat 12. The inside of the bearing seat 12 is rotatably connected with a rotating cylinder 11. The inside of the rotating cylinder 11 is movably connected with a transmission shaft 6. The circumferential surface of the rotating cylinder 11 is fixedly connected with a transmission rod 8. A sliding hole 9 is formed in the upper end surface of the transmission rod 8. A sliding rod 10 is slidably connected inside the sliding hole 9. The lower end of the sliding rod 10 is fixedly connected with the extending end of the hydraulic telescopic rod 7. During operation, when the hydraulic telescopic rod 7 works, it can drive the sliding rod 10 to slide inside the sliding hole 9. Then, with the cooperation of the transmission rod 8, it can drive the rotating cylinder 11 to rotate inside the bearing seat 12. As the rotating cylinder 11 rotates, it can drive the transmission shaft 6 to rotate. In this way, it is convenient for the scraper 16 to approach the drum, which is beneficial for the scraper 16 to scrape off the filter cake on the drum.

[0030] A limiting groove 601 is formed in the circumferential surface of the transmission shaft 6. A limiting block 17 is slidably connected inside the limiting groove 601. The limiting block 17 is fixedly connected with the rotating cylinder 11. During operation, by arranging the limiting groove 601 and the limiting block 17, with the cooperation of the limiting groove 601 and the limiting block 17, it is convenient for the rotating cylinder 11 to stably drive the transmission shaft 6 to rotate.

[0031] The lifting mechanism includes a support frame 2, a motor 3, a lead screw 4 and a moving seat 5. The upper end of the centrifuge body 1 is fixedly connected with a support frame 2. The inside of the support frame 2 is rotatably connected with a lead screw 4. The circumferential surface of the lead screw 4 is threadedly connected with a moving seat 5. One end of the moving seat 5 away from the lead screw 4 is rotatably connected with the transmission shaft 6. The upper end of the support frame 2 is fixedly connected with a motor 3. The output end of the motor 3 is fixedly connected with the lead screw 4. During operation, when the motor 3 works, under the action of the lead screw 4, it can drive the moving seat 5 to move. As the moving seat 5 moves, at this time, it can drive the scraper 16 to move up and down, so as to clean the inner wall of the drum in all directions.

[0032] The connecting component includes a socket 13, a plug 14 and a locking screw 15. The lower end of the transmission shaft 6 is fixedly connected with a socket 13. A plug 14 is inserted inside the socket 13. The plug 14 is fixedly connected with the scraper 16. A locking screw 15 is threadedly connected inside the socket 13. During operation, by arranging the socket 13, the plug 14 and the locking screw 15, when the scraper 16 is damaged, first loosen the locking screw 15. At this time, it is convenient to remove the plug 14 from the inside of the socket 13, so as to facilitate the replacement of a new scraper 16, making the replacement of the scraper 16 more convenient and fast, thus improving the maintenance efficiency.

[0033] The lower end of the scraper 16 is provided with an inclined portion. During operation, by providing the inclined portion at the lower end of the scraper 16, it is convenient for the scraper 16 to move downward at this time, thereby reducing the resistance when the scraper 16 moves downward, which is beneficial for the scraper 16 to scrape the inner wall of the entire drum.
