Description

Technical Field

[0001] This invention relates to the field of coated sand processing technology, and more specifically to a coated sand cooling bed that is easy to adjust for coated sand processing. Background Technology

[0002] Coated sand is a molding material mainly made of quartz sand, binder, curing agent, lubricant, etc. through a specific process. The binder is generally an organic material such as phenolic resin, which forms a thin film on the surface of the sand grains, covering them. This is the origin of the term "coating". During its preparation, it needs to undergo heat treatment at high temperatures. To avoid damage to equipment and personnel caused by the high temperature of the coated sand, and to meet the temperature requirements of subsequent processing, effective cooling treatment is required. Therefore, a cooling bed has become an indispensable piece of equipment in the coated sand processing.

A knob is fixedly connected to the side end of the threaded rod 12. The upper surface of the baffle 10 is in contact with the inner top surface of the discharge trough 9. The bottom surface of the limiting plate 11 and the inner top surface of the discharge trough 9 are on the same plane.

[0032] Two cooling mechanisms are provided, each including an air-cooling assembly, a transmission assembly, and a tilting assembly. The air-cooling assembly includes a motor 16 fixedly connected to the side wall of the cooling bed 2 via a bracket. A first rotating shaft 17 is fixedly connected to the output end of the motor 16. The first rotating shaft 17 is rotatably connected to the inner wall of the cooling bed 2 via a bearing. A fan blade 18 is fixedly connected to the end of the first rotating shaft 17 away from the motor 16. A protective cover 19 is fixedly connected to the inner wall of the cooling bed 2. Multiple ventilation slots 20 are equidistantly arranged on the side wall of the cooling bed 2. The transmission assembly includes a mounting plate fixedly connected to the side wall of the cooling bed 2. A second rotating shaft 21 is located on the side of the cooling bed 2. The second rotating shaft 21 is rotatably connected to the side wall of the mounting plate via a bearing. A drive wheel 22 is fixedly connected circumferentially to the first rotating shaft 17. A drive wheel 22 is fixedly connected circumferentially to the second rotating shaft 21. A driven wheel 23 is fixedly connected to the drive wheel 22, and a belt 24 is fitted between the drive wheel 22 and the driven wheel 23. The turning assembly includes a third rotating shaft 25 located inside the cooling bed 2. The third rotating shaft 25 is rotatably connected to the side wall of the cooling bed 2 through a bearing. A first bevel gear 26 is fixedly connected to the side end of the second rotating shaft 21. A second bevel gear 27 is fixedly connected to the circumference of the third rotating shaft 25. The first bevel gear 26 meshes with the second bevel gear 27. Multiple turning plates 28 are fixedly connected to the circumference of the third rotating shaft 25 at equal intervals. The drive wheel 22 and the driven wheel 23 are both located outside the cooling bed 2. The diameter of the drive wheel 22 is larger than the diameter of the driven wheel 23. Two fan blades 18 are located inside two protective covers 19. Multiple ventilation slots 20 are arranged around the two first rotating shafts 17 to ensure the efficient operation of the air-cooling assembly.

[0033] The working principle of this invention is as follows: During use, the coated sand to be cooled is added into the cooling bed 2. Then, two motors 16 are started. Taking one cooling mechanism as an example, motor 16 drives the first rotating shaft 17 to rotate, which in turn drives the fan blades 18 to rotate. The rotating fan blades 18 cause airflow, thereby generating wind power to achieve air cooling of the coated sand in the cooling bed 2. It is important to note that the rotation speed of the fan blades 18 needs to be controlled. While achieving cooling, it is also necessary to avoid overheating the coated sand in the cooling bed 2. When the fan blades 18 are blowing air to cool the air, the rotation of the first rotating shaft 17 will drive the drive wheel 22 to rotate, which in turn drives the driven wheel 23 and the second rotating shaft 21 to rotate through the belt 24. The rotation of the second rotating shaft 21 drives the first bevel gear 26 to rotate. Through meshing transmission, it drives the second bevel gear 27 and the third rotating shaft 25 to rotate. The rotation of the third rotating shaft 25 drives multiple flipping plates 28 to revolve, which can turn over the coated sand in the cooling bed 2. In conjunction with the air cooling components, more efficient cooling treatment can be achieved.

[0034] After the cooling operation is completed, the coated sand in the cooling bed 2 needs to be collected. At this time, the cylinder 8 is activated, causing the output end of the cylinder to lift the moving seat 7. Under the push of the cylinder 8, the moving seat 7 slides along the two guide rods 6. At the same time, the guide rods 6 and the fixed plate 5 cause the cooling bed 2 to swing. Under the influence of the tilted cooling bed 2, the coated sand will gather on one side of the cooling bed 2. Then, by turning the knob, the threaded rod 12 will engage with the nut 13, and thus move relative to it, thereby causing the baffle 10 to move. With the baffle 10 moving, the discharge chute 9 is no longer restricted, and the coated sand in the cooling bed 2 can be poured out through the discharge chute 9. It can then be collected directly at the output end of the discharge chute 9. This method is efficient, convenient, and has low labor intensity.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
