[0022] The output end of the first drive motor 7 is fixedly connected to the top of the centrifuge 4, the two sides of the bottom end of the support frame 5 are installed inside the mounting groove 17, the second scraper 12 is arranged on the outer wall of the centrifuge 4, and the first scraper 3 is arranged on the inner wall of the outer shell 1;

[0023] Specifically, Figure 1 and Figure 3As shown, the second drive motor 8 drives the connecting plate 9 to rotate through the coupling. The rotation of the connecting plate 9 can drive the first connecting rod 6 and the second connecting rod 11 to rotate inside the outer shell 1, so that the first scraper 3 and the second scraper 12 can scrape the acid adhered to the inner wall of the outer shell 1 and the outer wall of the centrifuge 4. Scraping the acid adhered to the inner wall of the outer shell 1 and the outer wall of the centrifuge 4 can not only prevent the acid from adhering to the inner wall for a long time and being difficult to clean, but also prevent the acid from adhering to the inner wall for a long time and affecting the service life of the outer shell 1 and the centrifuge 4.

[0024] Embodiment 2: A filter hole 19 is provided inside the support plate 2, support blocks 16 are fixedly connected to both sides of the bottom end of the outer shell 1, a storage drawer 13 is provided on the top of the support block 16, a handle 15 is fixedly connected to one end of the storage drawer 13, a reserved groove 14 is provided at the bottom end of the inner part of the outer shell 1, and the storage drawer 13 is arranged inside the reserved groove 14;

[0025] Specifically, Figure 1 and Figure 2 As shown, the acid thrown out of the centrifuge 4 and the acid scraped off will flow into the storage drawer 13 through the filter holes 19 inside the support plate 2. The acid flowing into the storage drawer 13 can facilitate unified treatment of the acid. When there is a lot of acid in the storage drawer 13, the handle 15 is pulled, and the handle 15 drives the storage drawer 13 to leave the reserved groove 14, so that the acid in the storage drawer 13 can be easily treated.

[0028] Working principle: when the utility model is in use, the first drive motor 7 is started, and the first drive motor 7 drives the centrifuge 4 to rotate. The rotation of the centrifuge 4 can make the acid in the nitrocellulose be thrown out of the inside of the centrifuge 4. When the centrifuge 4 rotates, the support sleeve 22 will rotate inside the limiting sleeve 23. The support sleeve 22 and the limiting sleeve 23 can support and limit the centrifuge 4. When the support sleeve 22 rotates inside the limiting sleeve 23, the ball 21 inside the rolling groove 20 can reduce the friction between the support sleeve 22 and the limiting sleeve 23. Reducing the friction between the support sleeve 22 and the limiting sleeve 23 can not only increase the service life of the support sleeve 22 and the limiting sleeve 23, but also facilitate the rotation of the centrifuge 4 and improve the working efficiency of the centrifuge 4. After the acid is thrown out of the inside of the centrifuge 4, the second drive motor 8 is started, and the second drive motor 8 drives the connecting plate 9 to rotate through the coupling. The rotation of the connecting plate 9 can drive the first connecting rod 6 and the second connecting rod 11 to rotate inside the outer shell 1, so that the first scraper 3 and the second scraper 12 can scrape the acid adhered to the inner wall of the outer shell 1 and the outer wall of the centrifuge 4. Scraping the acid adhered to the inner wall of the outer shell 1 and the outer wall of the centrifuge 4 can not only prevent the acid from adhering to the inner wall for a long time and being difficult to clean, but also prevent the acid from adhering to the inner wall for a long time and affecting the service life of the outer shell 1 and the centrifuge 4. The acid thrown out of the centrifuge 4 and the scraped acid will flow into the storage drawer 13 through the filter hole 19 inside the support plate 2. The acid flowing into the storage drawer 13 can facilitate unified treatment of the acid. When there is a lot of acid in the storage drawer 13, pull the handle 15, and the handle 15 drives the storage drawer 13 to separate from the reserved groove 14, so that the acid in the storage drawer 13 can be conveniently treated.
