Description

Technical Field

[0001] The utility model relates to the technical field of resin sand recovery, in particular to a resin sand recovery device. Background Art

[0002] Resin sand recycling refers to the process of treating and reusing used resin sand. Resin sand is usually used in the foundry industry to make casting molds. After use, resin sand may contain various impurities and needs to be recycled and treated for reuse or resource utilization to reduce the impact on the environment.

[0003] The Chinese patent publication number is CN218109263U. It discloses a cooling device for the resin sand recovery process. The resin sand can be turned over to facilitate the cooling fan limiter sleeve to rotate and blow air synchronously at the right end. This solves the problem that the resin sand cannot be turned over during the cooling process, resulting in a slow cooling speed, and it is inconvenient to turn the resin sand by rotating the drum and drive the fan to blow air to accelerate cooling.

[0004] With respect to the above-mentioned related technologies, the device has some shortcomings. In actual use, firstly, both loading and unloading need to be done manually, which increases the complexity and time cost of the operation. Secondly, during the cooling process of the resin sand, the air blowing cooling fan needs to be manually operated, which is not only inefficient but also has safety hazards. Therefore, it is necessary to provide a resin sand recovery device to solve the above technical problems. Utility Model Content

[0032] A slideway 19 is provided on the inner surface of the annular support 6 , a plurality of sliders 18 are fixedly mounted on the outer wall of the turning cylinder 2 , and the sliders 18 are slidably connected to the slideway 19 , and a driving mechanism is provided on the upper side of the outer surface of the annular support 6 .

[0033] The slider 18 is T-shaped and matched with the slideway 19 . A plurality of mounting grooves 16 are provided on the sliding contact surfaces between the protrusions on both sides of the slider 18 and the slideway 19 . Balls 17 are movably mounted on the mounting grooves 16 , and the balls 17 are in rolling contact with the inner wall of the slideway 19 .

[0034] In one embodiment, the driving mechanism includes a motor 7, and the motor 7 is fixedly mounted on the upper side of the outer surface of the annular support 6, a gear 8 is fixedly mounted on the driving end of the motor 7, an annular rack 9 is fixedly mounted on one side of the annular support 6 on the outer wall of the flip cylinder 2, and the annular rack 9 is meshed with the gear 8, thereby realizing the rotation effect of the flip cylinder 2.

[0035] In one preferred embodiment, the inner diameter of the annular support member 6 is larger than the outer diameter of the turning cylinder 2 , so as to avoid frictional contact between the outer wall of the turning cylinder 2 and the inner wall of the annular support member 6 .

[0036] In one embodiment, the outer diameter of the air-permeable cloth cylinder 14 is smaller than the inner diameter of the turning cylinder 2, so that the wind can flow more smoothly inside the device, effectively improving the cooling efficiency of the resin sand.

[0037] In one of the preferred embodiments, both ends of the flip cylinder 2 are open structures, one end of the breathable cloth cylinder 14 is open structure, and one end of the breathable cloth cylinder 14 is in contact with one side of the end cover 3, so that wind can enter the interior of the device to quickly cool the resin sand inside the device. By in contact with one end of the breathable cloth cylinder 14 and one side of the end cover 3, the sealing effect of the end cover 3 on the port of the breathable cloth cylinder 14 in the closed state is ensured to prevent leakage of resin sand during the flipping process.

[0038] The working principle of the utility model is as follows: the electrical components appearing in the article are all connected to the external main controller and the 220V mains electricity, and the main controller can be a conventional known device that controls a computer, etc. When in use, first control the hydraulic telescopic rod 4 to start working, the extension of the driving end of the hydraulic telescopic rod 4 drives the connecting plate 5 to move upward, and the connecting plate 5 drives the turning cylinder 2 to turn upward with the hinge point of the fan 12 and the support frame 10 as the origin through the cooperation of the annular support member 6 and the slider 18. After the turning cylinder 2 is turned upward by a certain angle, the lock buckle 13 is manually unlocked, and then the end cover 3 is opened. The resin sand to be cooled is added into the air-permeable cloth cylinder 14 through the port of the air-permeable cloth cylinder 14. After the addition of the resin sand is completed, the end cover 3 is closed and the lock buckle 13 is locked. Subsequently, the hydraulic telescopic rod 4 is driven to reset the turning cylinder 2 to a horizontal position. At this time, the control motor 7 and the fan 12 start to work. The driving end of the motor 7 drives the gear 8 to rotate, and the meshing of the gear 8 and the annular rack 9 drives the turning cylinder 2 to rotate. The rotation of the turning cylinder 2 drives the air-permeable cloth cylinder 14 to rotate through the mounting block 15, so that the air-permeable cloth cylinder 1 The resin sand inside the turning cylinder 2 is constantly turning over. The turning cylinder 2 will drive the slider 18 to slide on the slideway 19 during the turning process to ensure the stability of the turning cylinder 2 during the turning process. At the same time, due to the rotation relationship between the turning cylinder 2 and the annular movable part 11, the turning cylinder 2 will not drive the fan 12 to rotate through the annular movable part 11. After the fan 12 starts working, it will generate a high-speed airflow that will directly blow into the inside of the turning cylinder 2 from the right port of the turning cylinder 2. After entering the inside of the turning cylinder 2, the wind will directly enter the inside of the breathable cloth cylinder 14 to the turning state of the inside of the breathable cloth cylinder 14. The resin sand is cooled. After the resin sand is cooled, the hydraulic telescopic rod 4 is driven to tilt the turning cylinder 2 to a certain angle to the lower left. At this time, the end cover 3 is opened, and the resin sand inside the breathable cloth cylinder 14 will be quickly discharged through the left port of the breathable cloth cylinder 14 along the tilt direction of the breathable cloth cylinder 14. After the discharge is completed, the above steps can be repeated to continue cooling the resin sand. During the entire use of the device, the angle change of the turning cylinder 2, its own rotation and the operation of the fan 12 are all completed automatically, completely relying on mechanized operation. This highly mechanized design makes manual assisted operation very simple, greatly reducing the complexity of operation, time cost and safety hazards. During use, people only need to supervise the operation of the device without frequent manual intervention. This not only improves the convenience of operation, but also significantly improves the recovery efficiency of resin sand, making the entire process more efficient.
