Technical Field
[0001] This utility model relates to the technical field of sand removal devices, and in particular to a sand removal device for castings with a filtration function. Background Technology
[0002] Casting involves pouring liquid metal into a casting cavity that conforms to the shape of the part. After the casting cools and solidifies, the mold needs to be broken to separate the mold from the sand box and the casting from the molding sand. This process is quite common in daily life.
[0003] Existing casting sand removal devices use vibration to separate sand from castings during use. However, the sand removed from castings can be reused, which greatly improves utilization and saves costs for enterprises. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.
[0022] Reference Figures 1-3 A casting sand removal device with filtering function includes a frame 1. Cylinders 11 are bolted to the inner walls of both sides of the frame 1. A fixing frame 16 is bolted to the outer wall of one side of the cylinder 11. A motor is bolted to the inner wall of one side of the fixing frame 16. The output shaft of the motor passes through the cylinder 11 and is keyed to a rotating shaft 18. Multiple discs 17 are welded to the outer circumference of the rotating shaft 18. Multiple rods 13 are welded between adjacent discs 17. Multiple grinding blocks 14 are rotatably connected to the outer circumference of the rods 13. Grinding cylinders 12 are welded to the inner walls of both sides of the cylinder 11, and the multiple discs 17 are all located inside the grinding cylinders 12. The bottom of the cylinder 11 is provided with a discharge port 15. In use, the sand falls into the grinding cylinder 12. Then the motor is started, and the motor output shaft drives the rotating shaft 18 to rotate, thereby causing the disc 17 and the rod 13 to rotate. This causes the grinding block 14 to perform centrifugal motion, thereby crushing and grinding the sand. When the size of the sand is smaller than the hole of the grinding cylinder 12, it is discharged through the hole of the grinding cylinder 12 and collected by the arc-shaped inner wall of the cylinder 11, and then discharged from the discharge port 15. Since the size of the hole of the grinding cylinder 12 is fixed, the crushed sand can be directly reused, which improves the applicability of the equipment.
[0023] In this invention, a spring 7 is bolted to the top outer wall of the frame 1, and a box 4 is bolted to the other end of the spring 7. Vibration motors 5 are bolted to the outer walls of both sides of the box 4. Limiting frames 2 are welded to the outer walls of the frame 1, and the box 4 is located within the limiting frames 2. When the vibration motor 5 operates, it causes the box 4 to vibrate. The limiting frames 2 limit the vibration and prevent excessive shaking. Rubber pads are adhered to the inner walls of multiple sides of the limiting frames 2, with the top of the rubber pads higher than the top of the limiting frames 2 to reduce damage when the box 4 contacts the limiting frames 2. Placement racks 9 and filter screens 10 are welded to the inner walls of multiple sides of the box 4, with the placement rack 9 positioned above the filter screen 10. When a casting is placed on the placement rack 9, vibration causes sand to detach from the casting and fall through the placement rack 9 onto the filter screen 10. Due to the varying sizes of the sand, finer sand will pass through the filter screen 10 and fall, while larger sand will remain on the filter screen 10. For better filtration, two guide rails 6 are fixed to the outer walls of both sides of the housing 4 by bolts. A baffle 3 is slidably connected between the two guide rails 6 on the same side. A threaded hole is opened on one side of the baffle 3, and a screw is threaded into the threaded hole. One end of the screw contacts the housing 4. During vibration, the baffle 3 prevents sand from falling. The outer walls of both sides of the housing 4 have discharge ports 8, and the baffle 3 blocks the discharge ports 8. After vibration, larger sand is taken out through the discharge ports 8, which facilitates the unified collection of larger sand. The bottom of the inner walls of the housing 4 is inclined. A connecting sleeve 19 is fixed to the bottom of the housing 4 by bolts. The connecting sleeve 19 is fixed to the cylinder 11. The material of the connecting sleeve 19 is rubber. During vibration, the inclined surface gathers and guides smaller sand, reducing the time smaller sand stays on the inner wall of the housing 4 and avoiding excessive accumulation. The sand enters the grinding cylinder 12 through the connecting sleeve 19.
[0024] Working principle: When the casting is placed on the placement rack 9, the vibration motor 5 is started, which causes the housing 4 to vibrate. The vibration causes the sand to detach from the casting and fall through the placement rack 9 onto the filter screen 10. Since the sand size varies, the finer sand will fall through the filter screen 10, while the larger sand will remain on the filter screen 10. The larger sand pieces are blocked by the baffle 3 at the discharge port 8 and discharged. The smaller sand pieces enter the grinding cylinder 12 through the connecting sleeve. Then the motor is started, and the motor output shaft drives the rotating shaft 18 to rotate, thereby causing the disc 17 and the rod 13 to rotate. This causes the grinding block 14 to perform centrifugal motion, thereby crushing and grinding the sand. When the size of the sand is smaller than the hole of the grinding cylinder 12, it is discharged through the hole of the grinding cylinder 12 and collected by the arc-shaped inner wall of the cylinder 11, and then discharged from the discharge port 15. Since the size of the hole of the grinding cylinder 12 is fixed, the crushed sand can be directly reused, which improves the applicability of the equipment.
[0025] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
