Description

Technical Field

[0001] The utility model relates to the technical field of foundry sand processing, in particular to a heat dissipation device of sand processing equipment for manhole cover casting. Background Art

[0002] Foundry sand is generally a high-energy, high-cost material, and its cost includes not only the raw material cost, but also the preparation, molding, processing and disposal costs. By recycling and reusing foundry sand, the raw material cost of the casting process can be significantly reduced and resource utilization efficiency can be improved. Foundry sand may be affected by high temperatures during the casting process, especially when it is in direct contact with the casting or molten metal, it will absorb a lot of heat. If it is rapidly cooled or directly reused without sufficient heat dissipation, it may cause thermal stress caused by the residual heat inside the sand. This thermal stress can cause cracks or damage inside the sand, reducing its strength and durability. When the foundry sand is recycled, the foundry sand processing equipment is prone to overheating and causing equipment failure.

The high temperature of the casting sand will affect the overall processing equipment.

[0016] refer to Figures 1 to 4The heat dissipation device of the sand processing equipment for manhole cover casting shown in the figure comprises a cooling box 1 for transporting casting sand, a feeding port 5 is arranged on the cooling box 1, the feeding port 5 breaks up the casting sand, increases the contact area between the casting sand and the air outlet pipe 6, and improves the heat dissipation efficiency of the casting sand, a plurality of groups of baffles 7 are arranged in the discharge port 2, the baffles 7 block the wind discharged from the cooling box 1 to prevent the casting sand from being blown away by excessive wind force, and a plurality of groups of height-adjustable air outlet pipes 6 are arranged inside the cooling box 1, the air outlet pipes 6 discharge cold air, and dissipate heat to the casting sand and the cooling box 1 at the same time.

[0017] The cooling box 1 is arranged obliquely on the ground, a feed port 5 is arranged at the higher end of the cooling box 1, a discharge port 2 is arranged at the lower end of the cooling box 1, two groups of pressing plates 4 and stirring rollers 8 are rotatably arranged inside the feed port 5, and the foundry sand to be processed is fed into the cooling box 1 through the feed port 5. When the foundry sand is put into the feed port 5, the two groups of stirring rollers 8 are driven to rotate, and at the same time, one group of pressing plates 4 is fixed and the other group of pressing plates 4 is driven to rotate reciprocatingly. The two groups of pressing plates 4 are close to each other to squeeze the foundry sand, disperse the foundry sand to be processed, increase the contact area between the foundry sand and the cold air after entering the cooling box 1, and improve the heat dissipation efficiency of the foundry sand. The two groups of stirring rollers 8 further disperse the foundry sand and push the foundry sand to fall onto the sliding plate 12.

[0018] A cooling plate 3 and a support column 10 are slidably arranged on the cooling box 1, a spring 11 is arranged between the support column 10 and the cooling box 1, a cam 9 is rotatably arranged on the cooling box 1, the cam 9 is fitted with the support column 10, when the cam 9 is driven to rotate, the cam 9 drives the support column 10 to slide on the cooling box 1, and the support column 10 slides back and forth on the cooling box 1 through the deformation recovery force of the spring 11, the sliding plate 12 is installed in the support column 10, the sliding plate 12 slides in the cooling box 1, and a baffle 13 is arranged between the sliding plate 12 and the cooling box 1 to prevent the casting sand from entering between the cooling box 1 and the sliding plate 12 In the gap between the cooling boxes 1 and the cooling boxes 1, when the support column 10 slides back and forth, the support column 10 drives the sliding plate 12 to slide back and forth, and the casting sand moves in the cooling box 1 through the shaking of the sliding plate 12 and gravity, and the casting sand gradually approaches the discharge port 2. A plurality of groups of air outlet pipes 6 are arranged at the lower end of the cooling plate 3, and the air outlet pipes 6 are inserted into the casting in the cooling box 1. When dissipating heat, the air outlet pipes 6 discharge cold air, and the cold air discharged by the air outlet pipes 6 cools the cooling box 1 and the casting sand in the cooling box 1. The depth of the air outlet pipes 6 inserted into the casting sand is changed according to the amount of casting sand, so as to change the cooling effect and avoid energy waste.

[0019] Multiple groups of air outlets 14 are arranged on both sides of the cooling box 1, and filters are arranged on the air outlets 14. After the cold air discharged from the air outlet pipe 6 completes the heat exchange with the casting sand and the cooling box 1, it is discharged through the air outlet 14 and the discharge port 2. When the air is discharged through the air outlet 14, it will carry some casting sand with it. At this time, the filter on the air outlet 14 blocks the casting sand, which may cause the filter on the air outlet 14 to be blocked under long-term work. Two groups of scrapers 15 are slidingly arranged inside the cooling box 1. When the scraper 15 slides in the cooling box 1, it cleans the casting sand accumulated on the filter of the air outlet 14 to improve the exhaust effect.

[0020] Two sets of baffles 7 are arranged in the discharge port 2, one end of the baffle 7 is fixed in the discharge port 2, and the other end of the baffle 7 is blown by the air discharged from the cooling box 1. The baffle 7 slows down the air discharged from the cooling box 1 to prevent the wind force of the discharged gas from being too strong and blowing away the cooled casting sand.

[0021] Working principle: During operation, the foundry sand to be processed is put into the cooling box 1 through the feed port 5. At this time, one group of pressing plates 4 is fixed in the feed port 5, and the other group of pressing plates 4 is driven to reciprocate in the feed port 5. When the two groups of pressing plates 4 are close to each other, they squeeze the passing foundry sand to disperse the agglomerated foundry sand, and then drive the stirring roller 8 to rotate, and the stirring roller 8 drives the foundry sand to continue to move, and the foundry sand is placed on the sliding plate 12.

[0022] The driving cam 9 rotates, and the cam 9 drives the supporting column 10 to slide back and forth. The supporting column 10 drives the sliding plate 12 to vibrate in the cooling box 1. The casting sand in the cooling box 1 moves in the cooling box 1 through gravity and the vibration of the sliding plate 12, and the casting sand gradually approaches the discharge port 2. The cooling plate 3 is driven to slide in the cooling box 1, and the cooling plate 3 drives the air outlet pipe 6 to be inserted into the casting sand. The air outlet pipe 6 is driven, and the air outlet pipe 6 discharges cold air. The cold air dissipates the casting sand in the cooling box 1 and the inside of the cooling box 1. When the amount of casting sand on the sliding plate 12 increases, the cooling plate 3 is driven to move, and the cooling plate 3 drives the air outlet pipe 6 to continue to be inserted into the casting sand, thereby improving the heat dissipation efficiency of the casting sand. Subsequently, the casting sand after heat dissipation is discharged through the discharge port 2.

[0023] After the air discharged from the air outlet pipe 6 completes the heat exchange, it is discharged through the air outlet 14 and the discharge port 2. The filter on the air outlet 14 filters the discharged air. After working for a long time, the scraper 15 is driven to slide in the cooling box 1. The scraper 15 cleans the casting sand on the filter of the air outlet 14 to ensure the exhaust efficiency in the cooling box 1. Other gases are discharged through the discharge port 2. The gas blows the baffle cloth 7. The baffle cloth 7 slows down the speed of the gas discharged from the cooling box 1 to avoid the exhaust gas from being too strong and blowing the casting sand away to cause pollution and waste.
