Description

[0002] Regenerated sand is the old sand that has been processed in the foundry production and basically restored its performance and can be reused. In sand casting, 1 to 7 tons of used sand will be produced for every ton of castings produced. There are basically two ways to use old sand, namely, reuse of old sand and reuse of old sand after regeneration. After the casting, if the binder in most of the molding sand has not undergone irreversible changes, the original performance of the molding sand can be restored by removing impurities, cooling after ash absorption and remixing. This treatment method is called reuse of old sand. Generally, only molding sand bonded with clay can be reused.

The old sand needs to be washed with water initially, but will subsequently form clumps, which will affect the screening efficiency between the old sand and the mold; 2.

[0047] like Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, the screening mechanism 1 includes a central channel 11, the top of the central channel 11 is fixedly connected to the vibrator 4, the two ends of the central channel 11 are respectively fixedly connected to the No. 1 support rod 2 and the No. 2 support rod 3, the two ends of the inner cavity of the central channel 11 are symmetrically connected with inner rails 19, the inner part of the inner rail 19 is slidably adapted with a movable filter screen 10, the bottom of the movable filter screen 10 is slidably adapted with a bottom filter plate 101, the bottom filter plate 101 is fixedly connected to the bottom of the central channel 11, the bottom of the inner cavity of the central channel 11 is fixedly connected with a folding plate seat 102, the folding plate seat 102 is rotatably connected with a flip plate 103, the end of the flip plate 103 away from the folding plate seat 102 is fixedly connected with an adjustable plate 104, and the end of the adjustable plate 104 away from the flip plate 103 is inserted in the movable Inside the filter 10, the bottom of the adjustable plate 104 is fixedly connected to the first magnet 105, and the second magnet 106 is arranged below the first magnet 105. The bottom of the second magnet 106 is fixedly connected to the support plate 107, and the support plate 107 is fixedly connected to the bottom of the central channel 11. In addition, as the movable filter 10 moves outward along the inner rail 19, the adjustable plate 104 will be passively inserted into the interior of the movable filter 10, wherein the adjustable plate 104 is hinged to the folding plate seat 102 through the flip plate 103, and the first magnet 105 and the second magnet 106 maintain a repulsive relationship. Therefore, when the adjustable plate 104 is inserted into the movable filter 10, it will deflect upward to increase the degree of sliding of the mold.

[0048] A top plate 12 is fixedly connected to the top of the inner cavity of the central channel 11, and a shaft sleeve 14 is rotatably connected to the end of the top plate 12 away from the central channel 11. A fixed shaft 13 is rotatably connected inside the shaft sleeve 14, and the fixed shaft 13 is fixedly connected to the inner side of the central channel 11.

At this time, the vibrator 4 is started to vibrate the inner cavity of the central channel 11, so that the old sand will pass through the movable filter screen 10 and the bottom filter plate 101 respectively and shake into the funnel tube 51. In addition, when the old sand accumulates and clogs at the tail end of the central channel 11, the accumulation of the blockage will increase the friction between the movable filter screen 10 and the blockage, causing the blockage to move the movable filter screen 10 outward along the inner rail 19.

Then the magnetic absorber 53 will absorb the magnetic material in the old sand. In addition, when some molds move to the reset rotating plate 55, due to gravity, the reset rotating plate 55 will be deflected downward through the support 54, thereby screening out some small molds.

[0050] When the present invention is in use: first, old sand is thrown into the top of the feed inlet pipe 641, and the old sand will impact the stress arc plate 640 downward, and the stress arc plate 640 impacted will move downward with the blocking plate 649, and then the double-headed rod 648 connected to the two ends of the blocking plate 649 will move downward with the diamond plate 647 along the side through groove 646, wherein as the blocking plate 649 moves downward, the isolation net 644 will be exposed, so that the external connection frame 642 and the feed inlet pipe 641 will be connected to each other, and the heater 643 arranged inside the external connection frame 642 will generate heat and pass through the isolation net 644 into the feed inlet pipe 641.

At the same time, the hot air entering the No. 1 heat recovery pipe 65 will enter the impact plate 62 along its inner wall, and the old sand hitting the impact plate 62 will be initially crushed.

[0052] After the impact crushing is completed, the old sand will enter the central channel 11. At this time, the vibrator 4 is started to vibrate the inner cavity of the central channel 11, causing the old sand to be shaken downward through the movable filter 10 and the bottom filter plate 101 respectively, and the mold mixed in the old sand will be discharged outward along the surface of the movable filter 10. In addition, when the old sand accumulates and clogs at the tail of the central channel 11, the friction between the blockage and the movable filter 10 will increase, causing the blockage to carry the movable filter 10 to move outward along the inner rail 19. At this time, the movable filter 10 and the bottom filter plate 101 will be staggered, and the flow holes between the two will be greatly increased.

[0053] Finally, the old sand after filtration will enter the straight pipe 58 through the funnel tube 51, and then the motor connected to the rotating blade 52 will be started, so that the rotating blade 52 will rotate and transport and disperse the old sand.
