The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0023] According to an embodiment of the present invention, a circulating water filtration device for a plastic granule dewatering machine is provided.
[0024] Example 1;
[0025] like Figure 1-5 As shown, the circulating water filtration device for a plastic granule dewatering machine according to an embodiment of the present utility model includes a filter box 1, a water storage tank 2 connected to the bottom of the filter box 1, a water inlet pipe 3 symmetrically arranged at the top of the filter box 1, a water outlet pipe 4 on the outer wall of the filter box 1, a conical filter screen 5 in the filter box 1, and a dirt removal component at the top of the conical filter screen 5.
[0026] Example 2;
[0027] like Figure 1-5As shown, the system includes a filter box 1, a water storage tank 2 connected to the bottom of the filter box 1, symmetrically arranged water inlet pipes 3 at the top of the filter box 1, and a water outlet pipe 4 on the outer wall of the filter box 1. A conical filter screen 5 is installed inside the filter box 1, and a dirt removal component is installed at the top of the conical filter screen 5. Several evenly distributed cleaning covers 6 are located at the bottom of the filter box 1. Several evenly distributed support blocks 7 are located at the bottom of the water storage tank 2, and shock-absorbing pads are installed at the bottom of the support blocks 7. A conveying pump 8 is installed on the water outlet pipe 4. The dirt removal component includes a drive shaft 9 located at the top of the filter box 1, a connecting plate 10 at the bottom of the drive shaft 9, and inclined scrapers 12 on both sides of the connecting plate 10 that match the conical filter screen 5. The two sets of scrapers 12 are arranged in a circumferential array, and a feeding trough 13 is opened on one side of each set of scrapers 12, with a conveying component installed in the feeding trough 13. The top of the drive shaft 9 extends outside the filter box 1 and is connected to the drive end of a drive motor 14. The conveying assembly includes a conveying shaft 15 disposed in the feed trough 13. A spiral conveying blade 16 is fixedly sleeved on the outer wall of the conveying shaft 15. One end of the conveying shaft 15 extends to the outside of the scraper 12 and is connected to a helical gear 17. A helical gear 18 matching the helical gear 17 is sleeved on the outer wall of the drive shaft 9. The helical gear 18 is connected to the filter box 1 through a fixing bracket 11. A through hole matching the drive shaft 9 is opened on the helical gear 18.
[0028] In practical applications, the cooling water separated by the plastic granule dewatering machine is introduced into the filter box 1 through the inlet pipe 3. Then, it passes through the conical filter screen 5 to filter and intercept residual plastic granules. The filtered cooling water enters the storage tank 2 for storage. When it is necessary to clean the conical filter screen 5, the drive motor 14 is started to drive the drive shaft 9 to rotate. The drive shaft 9 drives the connecting plate 10 to rotate, and the connecting plate 10 drives the scraper 12 to rotate, scraping the surface of the conical filter screen 5 and scooping the plastic granules into the feed trough 13. When the scraper 12 rotates, it drives the helical gear 17 to revolve around the helical gear 18. Because the helical gear 17 meshes with the helical gear 18, the helical gear 17 rotates on its own axis. Wheel 17 drives the spiral conveyor blade 16 to rotate via the conveyor shaft 15, conveying the plastic particles in the feed trough 13 to the bottom side of the conical filter screen 5 for centralized collection, preventing the filter holes of the conical filter screen 5 from clogging. Finally, the unified processing personnel can open the cleaning cover 6 to discharge the particles. By setting the impurity removal component, the conical filter screen can be automatically cleaned to prevent the filter holes from clogging, eliminating the need for manual cleaning and saving more time and effort. At the same time, the impurity removal component, through the cooperation of the drive shaft, connecting plate, scraper, conveyor shaft, spiral conveyor blade, helical gear one and helical gear two, rotates and scrapes the outer wall of the conical filter screen, collecting the plastic particles in the feed trough, and then conveying them to the bottom side of the conical filter screen for unified processing via the spiral conveyor blade.
[0029] In summary, by means of the above-mentioned technical solution of this utility model, the conical filter screen can be automatically cleaned by setting the impurity removal component, preventing the filter holes from becoming clogged. This eliminates the need for manual cleaning, saving time and effort. At the same time, the impurity removal component, through the cooperation of the drive shaft, connecting plate, scraper, conveying shaft, spiral conveying blade, helical gear one, and helical gear two, rotates and scrapes the outer wall of the conical filter screen, collecting plastic particles in the feed trough. Subsequently, the particles are conveyed by the spiral conveying blade to the bottom side of the conical filter screen for unified processing.
