[0019] Embodiment: As Figures 1 - 5 shown, the present invention provides an impurity screening device for the production of silicone resin, including a screening barrel 1. A barrel cover 2 is arranged at the top end of the screening barrel 1. Clamping rings 3 are fixedly connected between the bottom end of the inner wall of the screening barrel 1 and the bottom end of the barrel cover 2. A filter cylinder 4 is movably sleeved between the outer sides of the two clamping rings 3. A rotating ring 5 is rotatably connected to the bottom end of the barrel cover 2 and located outside the clamping ring 3. A scraper 9 symmetrically distributed around the center is fixedly connected to the bottom end of the rotating ring 5. The scraping surface of the scraper 9 is in contact with the outer side of the filter cylinder 4.

[0020] Chute slots 11 are opened on both sides of the top of the screening barrel 1 and both sides of the barrel cover 2. Two fixing blocks 12 are rotatably connected to the side of the screening barrel 1 close to the chute slots 11. A rotating block 13 is rotatably connected between the two fixing blocks 12. A threaded rod 14 is fixedly connected to the top end of the rotating block 13. The threaded rod 14 is movably clamped in the chute slot 11. A turning handle 15 is threadedly connected to the outer side of the threaded rod 14. The bottom surface of the turning handle 15 abuts against the top end of the barrel cover 2.

[0021] By adopting the above technical solution, when closing the barrel cover 2, by aligning the positions of the chute slots 11 on the screening barrel 1 and the barrel cover 2, and then making the threaded rod 14 clamped into the corresponding two chute slots 11, and by rotating the turning handle 15 downward, the bottom surface of the turning handle 15 is in close contact with the top end of the barrel cover 2, so that the screening barrel 1 and the barrel cover 2 are in close contact, and the position of the barrel cover 2 is fixed.

[0022] Push plates 10 are fixedly connected to the sides of the bottom of the scraper 9 far away from the filter cylinder 4. A slag discharge pipe 17 communicating with the inside of the screening barrel 1 is fixedly connected to one side of the bottom end of the screening barrel 1.

[0023] By adopting the above technical solution, by arranging the push plates 10, it is convenient to push the impurities scraped off the outer side of the filter cylinder 4 to one side of the slag discharge pipe 17 and discharge them by using the slag discharge pipe 17.

[0024] A conical hopper 19 is fixedly connected to the middle of the bottom end of the screening barrel 1.

[0025] By adopting the above technical solution, by arranging the conical hopper 19, it is convenient for the filtered resin inside the screening barrel 1 to flow out better.

[0026] One side of the top end of the screening barrel 1 is fixedly connected with a feed pipe 18, and the bottom end of the conical hopper 19 is fixedly connected with a discharge pipe 20.

[0027] By adopting the above technical solution, by setting the feed pipe 18, it is convenient to inject resin into the interior of the screening barrel 1, and the filtered resin is discharged through the discharge pipe 20.

The driving end of the stepping motor 7 extends below the barrel cover 2 and is fixedly connected with a gear 8. The toothed ring 6 and the gear 8 are meshed and connected.

[0029] By adopting the above technical solution, the stepping motor 7 drives the gear 8 to rotate. By using the meshed connection between the toothed ring 6 and the gear 8, the rotating ring 5 is driven to rotate at the same time, so as to drive the scraping plate 9 to move along the outer side of the filter cylinder 4, and the impurities attached to the outer side of the filter cylinder 4 are scraped off by the scraping plate 9.

[0030] Working principle: When screening impurities in silicone resin, the unscreened silicone resin is injected into the interior of the screening barrel 1 from one end of the feed pipe 18. The silicone resin is filtered by the filter cylinder 4, so that the impurities in the silicone resin adhere to the outer surface of the filter cylinder 4. The filtered silicone resin enters the interior of the filter cylinder 4 and is discharged through the channel formed by the conical hopper 19 and the discharge pipe 20.

[0031] After the filter cylinder 4 is used for a period of time, the stepping motor 7 drives the gear 8 to rotate. By using the meshed connection between the toothed ring 6 and the gear 8, the rotating ring 5 and the push plate 10 are driven to rotate at the same time, so as to drive the scraping plate 9 to move along the outer side of the filter cylinder 4. The impurities attached to the outer side of the filter cylinder 4 are scraped off by the scraping plate 9, and the scraped impurities are pushed to the top end of the slag discharge pipe 17 by the push plate 10 and discharged through the slag discharge pipe 17.
