The Chinese utility model patent, with the authorization announcement number "CN218901040U", discloses a scraper mechanism for scraping the filter cake of a belt filter press. By adopting the above technical solution, since this scraper mechanism uses a separate adjustment component, it does not affect the use of other scrapers, and the pressure can be adjusted separately according to the wear degree of the scraper, avoiding the uneven pressure caused by the wear of the scraper and the failure of the spring, which may lead to poor mud scraping effect, and the operation is simple and fast.
[0003] In the use of the above technical solution, although it can avoid the uneven pressure caused by the wear of the scraper and the failure of the spring, which may lead to poor mud scraping effect, when the scraper cleans the filter cake, part of the filter cake will adhere to the scraper, which easily causes the filter cake adhered to the scraper to adhere to the pressure roller again, and then leads to poor cleaning effect of the scraper.

[0026] Please refer to Figures 1-4 , the present utility model provides a technical solution: a scraper assembly for a filter press, including:
[0027] The filter press frame 1 is internally rotatably installed with a pressure roller 3. One side of the filter press frame 1 is fixedly connected with two fixing plates 4. The inside of the two fixing plates 4 is bolted with a rotating plate 5. One side of the rotating plate 5 is installed with a tool mounting bracket 15, and a scraping knife 7 is bolted on the tool mounting bracket 15;
[0028] A scraping knife cleaning structure, which is located on the scraping knife 7;
[0029] The scraping knife cleaning structure includes a driving motor 12, a threaded rod 13 and a cleaning scraper 11. The driving motor 12 is fixedly installed on one side of the scraping knife 7. A sliding groove 8 is opened on the side of the scraping knife 7 away from the tool mounting bracket 15. The sliding groove 8 is "L"-shaped. The threaded rod 13 is rotatably connected inside the sliding groove 8. The output end of the driving motor 12 rotatably penetrates through one side of the sliding groove 8 and is fixedly connected with the threaded rod 13. The cleaning scraper 11 is threadedly sleeved on the outer surface of the threaded rod 13. The cleaning scraper 11 is slidably connected inside the sliding groove 8. The cleaning scraper 11 is in contact with the scraping knife 7.
[0030] One side of the filter press frame 1 is bolted with two rotating clamps 10. The two ends of the pressure roller 3 are respectively rotatably connected inside the corresponding rotating clamps 10. One side of the filter press frame 1 is fixedly installed with a driving motor 2. The output end of the driving motor 2 rotatably penetrates through one side of the filter press frame 1 and is fixedly connected with the pressure roller 3. The inside of the tool mounting bracket 15 is threadedly connected with two locking screws 9. The tool mounting bracket 15 is fixedly installed on the rotating plate 5 through the two locking screws 9. Two through holes 17 are opened on the side of the tool mounting bracket 15 away from the rotating plate 5.
[0031] One side of the rotating plate 5 close to the tool mounting bracket 15 is fixedly connected with two adjusting screws 16. The two adjusting screws 16 are respectively located inside the corresponding through holes 17. Nuts 6 are threadedly connected on the outer surfaces of the two adjusting screws 16. Springs 14 are sleeved on the outer surfaces of the two adjusting screws 16. One end of each of the two springs 14 is fixedly connected with the tool mounting bracket 15. The other ends of the two springs 14 away from the tool mounting bracket 15 are fixedly connected with the corresponding nuts 6.
[0032] Further, when using the device, the drive motor 2 is started by connecting an external power supply. The drive motor 2 drives the pressure roller 3 to rotate, so that the scraper 7 can scrape the filter cake on the pressure roller. Subsequently, the drive motor 12 is started by connecting an external power supply. The drive motor 12 drives the threaded rod 13 to rotate. The rotation of the threaded rod 13 drives the cleaning scraper 11 to move horizontally under the guidance of the sliding groove 8, so that the cleaning scraper 11 can clean the miscellaneous materials adhered to the scraper 7. By rotating the two nuts 6, the two nuts 6 will squeeze the corresponding springs 14, thereby facilitating the adjustment of the position between the tool mounting bracket 15 and the rotating plate 5. Subsequently, by screwing the two locking screws 9, it is convenient to fix the adjusted tool mounting bracket 15, and further facilitate the adjustment and fixation of the scraper 7.
[0033] Through the cooperation of the drive motor 12, the threaded rod 13 and the cleaning scraper 11, the threaded rod 13 can drive the cleaning scraper 11 to clean the miscellaneous materials attached to the scraper 7. And through the set "L"-shaped sliding groove, the miscellaneous materials cleaned down are further prevented from affecting the threaded rod 13, thus avoiding part of the filter cake from adhering to the scraper 7 and further improving the cleaning effect of the scraper 7.
[0034] Working principle: The drive motor 2 is started by connecting an external power supply. The drive motor 2 drives the pressure roller 3 to rotate, so that the scraper 7 can scrape the filter cake on the pressure roller. Subsequently, the drive motor 12 is started by connecting an external power supply. The drive motor 12 drives the threaded rod 13 to rotate. The rotation of the threaded rod 13 drives the cleaning scraper 11 to move horizontally under the guidance of the sliding groove 8, so that the cleaning scraper 11 can clean the miscellaneous materials adhered to the scraper 7. By rotating the two nuts 6, the two nuts 6 will squeeze the corresponding springs 14, thereby facilitating the adjustment of the position between the tool mounting bracket 15 and the rotating plate 5. Subsequently, by screwing the two locking screws 9, it is convenient to fix the adjusted tool mounting bracket 15, and further facilitate the adjustment and fixation of the scraper 7.
[0035] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present invention.
