[0030] Please see Figure 1-7 This utility model provides a technical solution:

[0031] A crushing device for recovering coated sand includes a base 1, a crushing cylinder 2 fixedly installed above the base 1, a feeding channel 3 fixedly connected to the top of the crushing cylinder 2, a rotating rod 4 rotatably installed inside the crushing cylinder 2, and uniformly distributed and symmetrically arranged cutting blades 5 fixedly installed on the rotating rod 4. An arc-shaped filter plate 6 is provided on the bottom surface of the crushing cylinder 2, and a conveying channel 7 is fixedly connected to the bottom surface of the crushing cylinder 2 at the arc-shaped filter plate 6. A bottom cylinder 8 is fixedly connected to the bottom of the conveying channel 7, a movable disk 9 rotatably installed inside the bottom cylinder 8, a rotating rod 10 is provided inside the bottom cylinder 8, the rotating rod 10 is arranged on the movable disk 9, and distributed and symmetrically arranged movable columns 11 are fixedly installed on the rotating rod 10. A magnetic column is provided inside the movable column 11. A driving component 12 for driving the rotating rod 4, cutting blades 5, movable disk 9, rotating rod 10, and movable column 11 to rotate synchronously is provided on the sides of the crushing cylinder 2 and the bottom cylinder 8. The bottom surface of the bottom cylinder 8 is provided with... An arc-shaped filter plate 13 is provided. A material discharge channel 14 is fixedly connected to the bottom surface of the bottom cylinder 8 at the arc-shaped filter plate 13. An electric telescopic column 15 is fixedly installed on the side of the material discharge channel 14. An arc-shaped sealing plate 16 is slidably arranged on the side of the material discharge channel 14. The end of the output shaft of the electric telescopic column 15 is fixedly installed with the end side of the arc-shaped sealing plate 16. The driving component 12 includes a drive motor 121 fixedly installed on the side of the crushing cylinder 2 and a drive motor 121 rotatably arranged on the side of the crushing cylinder 2. The drive wheel 122, the driven wheel 123 rotatably mounted on the side of the bottom cylinder 8, and the belt 124 sleeved on the drive wheel 122 and the driven wheel 123 are provided. The output shaft end of the drive motor 121 is fixedly installed with the middle of the drive wheel 122. The shaft end of the drive wheel 122 is fixedly installed with the shaft end of the rotating rod 4. The shaft end of the driven wheel 123 is fixedly installed with the shaft end of the movable disc 9. The belt 124 is meshed and driven by the drive wheel 122 and the driven wheel 123 respectively.

[0032] When in use, the base 1 is used to support the entire device;

[0033] When crushing and recycling coated sand, the coated sand is fed into the crushing cylinder 2 through the feeding channel 3. The drive motor 121 in the drive component 12 starts, driving the drive wheel 122 to rotate. The drive wheel 122 drives the driven wheel 123 to rotate through the belt 124. Since the shaft end of the drive wheel 122 is fixedly installed with the shaft end of the rotating rod 4, the rotation of the drive wheel 122 drives the rotating rod 4 to rotate, thereby causing the evenly distributed and symmetrically positioned cutting blades 5 fixed on the rotating rod 4 to rotate, thus crushing the coated sand in the crushing cylinder 2. The crushed coated sand enters the conveying channel 7 through the arc-shaped filter plate 6 and then falls into the bottom cylinder 8. Since the driven wheel 123 is fixedly installed at the shaft end of the driven wheel 123 and the shaft end of the movable disc 9, the driven wheel 123 drives the movable disc 9 to rotate as the belt 124 drives the driven wheel 123 to rotate. The movable disc 9 drives the rotating rod 10 to rotate, and the movable column 11 on the rotating rod 10 rotates accordingly. A magnetic column is installed inside the movable column 11. During the rotation of the movable column 11, the magnetic column adsorbs the metal impurities in the crushed coated sand.

[0034] When material needs to be discharged, the electric telescopic column 15 on the side of the discharge channel 14 is activated, and the end of its output shaft pushes the arc-shaped sealing plate 16 to slide, opening the discharge channel 14. The coated sand, after adsorbing metal impurities, enters the discharge channel 14 through the arc-shaped filter plate 13 for discharge.

[0035] This crushing device for coated sand recycling can directly adsorb metal impurities in the crushed coated sand, improving the purity of the recycled coated sand and making it highly practical.

[0036] Both the crushing cylinder 2 and the bottom cylinder 8 are threadedly connected to side covers 17;

[0037] Since both the crushing cylinder 2 and the bottom cylinder 8 are threadedly connected to the side cover 17, the side cover 17 can be removed from the side of the crushing cylinder 2 and the bottom cylinder 8 by rotating the side cover 17, which makes it easy to open the side of the crushing cylinder 2 and the bottom cylinder 8, and thus allows for the inspection, repair or replacement of the internal components.

[0038] A plug plate 18 is fixedly installed at the end of the rotating rod 10. A socket 19 is provided on the movable plate 9. The size of the plug plate 18 is adapted to the size of the socket 19, and a damping is provided between the plug plate 18 and the socket 19.

[0039] When a large amount of metal impurities are adsorbed on the movable column 11 and need to be cleaned, since the end of the rotating rod 10 is fixedly installed with a plate 18, and the movable plate 9 has a socket 19, and the size of the plate 18 is compatible with the size of the socket 19, and there is damping between the plate 18 and the socket 19, the operator can apply a certain pulling force to overcome the damping and pull the plate 18 out of the socket 19, so that the rotating rod 10 and the movable column 11 can be removed from the movable plate 9, which is convenient for cleaning the metal impurities adsorbed on the movable column 11. After cleaning, the plate 18 is inserted into the socket 19, and the damping is used to make the rotating rod 10 and the movable column 11 stably installed on the movable plate 9.

[0040] Arc-shaped filter plate 16 and arc-shaped filter plate 213 have the same mesh size;

[0041] The arc-shaped filter plate 6 and the arc-shaped filter plate 13 have the same mesh size, which can ensure the stable flow of the coated sand and avoid problems such as blockage or poor flow caused by inconsistent mesh size, thus ensuring the smooth progress of the entire crushing and recycling process.

[0042] The top surface of the feeding channel 3 is fitted with a top cover 20;

[0043] After the coated sand is fed into the crushing cylinder 2 through the feeding channel 3, the top cover 20 can be snapped onto the top of the feeding channel 3 to prevent dust from being blown out during the crushing process.

[0044] Working principle:

[0045] When in use, the base 1 is used to support the entire device;

[0046] When crushing and recycling coated sand, the coated sand is fed into the crushing cylinder 2 through the feeding channel 3. The drive motor 121 in the drive component 12 starts, driving the drive wheel 122 to rotate. The drive wheel 122 drives the driven wheel 123 to rotate through the belt 124. Since the shaft end of the drive wheel 122 is fixedly installed with the shaft end of the rotating rod 4, the rotation of the drive wheel 122 drives the rotating rod 4 to rotate, thereby causing the evenly distributed and symmetrically positioned cutting blades 5 fixed on the rotating rod 4 to rotate, thus crushing the coated sand in the crushing cylinder 2. The crushed coated sand enters the conveying channel 7 through the arc-shaped filter plate 6 and then falls into the bottom cylinder 8. Since the driven wheel 123 is fixedly installed at the shaft end of the driven wheel 123 and the shaft end of the movable disc 9, the driven wheel 123 drives the movable disc 9 to rotate as the belt 124 drives the driven wheel 123 to rotate. The movable disc 9 drives the rotating rod 10 to rotate, and the movable column 11 on the rotating rod 10 rotates accordingly. A magnetic column is installed inside the movable column 11. During the rotation of the movable column 11, the magnetic column adsorbs the metal impurities in the crushed coated sand.

[0047] When material needs to be discharged, the electric telescopic column 15 on the side of the discharge channel 14 is activated, and the end of its output shaft pushes the arc-shaped sealing plate 16 to slide, opening the discharge channel 14. The coated sand, after adsorbing metal impurities, enters the discharge channel 14 through the arc-shaped filter plate 13 for discharge.

[0048] This crushing device for coated sand recycling can directly adsorb metal impurities in the crushed coated sand, improving the purity of the recycled coated sand and making it highly practical.

[0049] in,

[0050] Since both the crushing cylinder 2 and the bottom cylinder 8 are threadedly connected to the side cover 17, the side cover 17 can be removed from the side of the crushing cylinder 2 and the bottom cylinder 8 by rotating the side cover 17, which makes it easy to open the side of the crushing cylinder 2 and the bottom cylinder 8, and thus allows for the inspection, repair or replacement of the internal components.

[0051] When a large amount of metal impurities are adsorbed on the movable column 11 and need to be cleaned, since the end of the rotating rod 10 is fixedly installed with a plate 18, and the movable plate 9 has a socket 19, and the size of the plate 18 is compatible with the size of the socket 19, and there is damping between the plate 18 and the socket 19, the operator can apply a certain pulling force to overcome the damping and pull the plate 18 out of the socket 19, so that the rotating rod 10 and the movable column 11 can be removed from the movable plate 9, which is convenient for cleaning the metal impurities adsorbed on the movable column 11. After cleaning, the plate 18 is inserted into the socket 19, and the damping is used to make the rotating rod 10 and the movable column 11 stably installed on the movable plate 9.

[0052] The arc-shaped filter plate 16 and the arc-shaped filter plate 213 have the same mesh size, which can ensure the stable flow of the coated sand and avoid problems such as blockage or poor flow caused by inconsistent mesh size, thus ensuring the smooth progress of the entire crushing and recycling process.

[0053] After the coated sand is fed into the crushing cylinder 2 through the feeding channel 3, the top cover 20 can be snapped onto the top of the feeding channel 3 to prevent dust from being blown out during the crushing process.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
