Description

Technical Field

[0001] The present application relates to the technical field of high-temperature sand cooling, and in particular to a high-temperature sand cooling device used in conjunction with a bucket elevator. Background Art

Due to its extremely high fire resistance and high temperature resistance, it is widely used in various industrial fields, such as high temperature equipment and refractory materials, furnaces and furnaces in metallurgy, steel, cement, chemical and petroleum industries.

[0003] The stepped quartz sand particle cooling machine mentioned in the existing Chinese public patent (authorization announcement number: CN215002529U), the finished quartz sand after high-temperature roasting enters the elevator through the feeding pulley transmission structure, is added to the cooling tank of the uppermost cooling box through the funnel, and slides down step by step to the lowermost cooling box under the vibration of the exciter, transfers the heat to the cooling water in the water box, and finally is sent to the next processing step through the discharge pulley transmission structure; the cooling water at the bottom of the heat dissipation pool enters the lowermost water box through the water inlet pipe under the action of the pump, moves upward step by step to the uppermost water box through the connecting pipe, performs heat exchange in the water box, and finally returns to the heat dissipation pool through the outlet pipe.

[0004] Currently, water cooling is mostly used to cool high-temperature sand. However, high-temperature sand is prone to form an uneven accumulation layer during movement, resulting in some sand particles being unable to directly contact the cooling water. These sand particles that are not in contact with the cooling water are not convenient for effectively transferring heat to the cooling water through conduction, which may result in poor cooling effect. Utility Model Content

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a high-temperature sand cooling device used in conjunction with a bucket elevator.

[0036] When cooling the high-temperature sand, the high-temperature sand is first lifted to the top of the discharge barrel 3 by the lifting machine body, and then the high-temperature sand is poured into the discharge barrel 3, and the high-temperature sand will enter the interior of the square warehouse 4 by gravity. At this time, the cooling water is transported to the water inlet pipe 9, so that the cooling water enters the cooling pipe 10 to absorb the heat emitted by the high-temperature sand. The cooling water flows inside the cavity, thereby absorbing the temperature of the high-temperature sand and reducing the temperature of the high-temperature sand. The cooling water can flow inside several square warehouses 4 through the connecting pipe 11, and the air cooling mechanism can slow down the sliding speed of the sand so that it can be fully cooled.

[0038] Among them, the square warehouse 4 is arranged in an inclined shape.

[0039] In addition, the cooling pipe 10 is provided in an S-shape.

[0040] When cooling the high-temperature sand, the air cooler is started to allow external air to enter the air cooler, so that the air cooler blows the high-temperature sand moving on the top of the square warehouse 4. The blowing action of the air cooler can slow down the sliding speed of the sand to a certain extent, so that the sand can be more evenly distributed in the square warehouse 4, thereby achieving the purpose of increasing the contact area between the high-temperature sand and the cooling water, thereby improving the cooling effect. By folding the square warehouse 4, the flow path length of the high-temperature sand in the square warehouse 4 can be increased, so that the high-temperature sand and the cooling water can be cooled for a longer time. By setting the cooling pipe 10 to an S shape, the actual length of the pipeline can be increased, further increasing the contact time between the cooling pipe 10 and the high-temperature sand, thereby improving the cooling effect.

[0042] Among them, the heat dissipation component includes positioning blocks 17 fixedly connected to both sides of the bottom wall of the water tank 15, and a heat dissipation tube 18 is slidably arranged between the positioning blocks 17 on both sides. The top of the heat dissipation tube 18 passes through the water tank 15 and is arranged to be open. A heat dissipation box 19 is fixedly connected to the top of the water tank 15, and the heat dissipation box 19 is connected to the heat dissipation tube 18.

[0043] In addition, bases 21 are fixedly connected to both sides of the top of the water tank 15 inside the heat dissipation box 19, a fan 22 is fixedly connected to the top of one side of the base 21, and ventilation holes 23 are opened on both sides of the heat dissipation tube 18.

[0044] In addition, a second fan 24 is fixedly connected to the top of the base 21 on the other side.

[0045] After the high-temperature sand is cooled, the cooling water that has absorbed the heat enters the water outlet pipe 13 through the cooling pipe 10, and the cooling water is continuously moved downward into the return pipe 14 through the connecting pipe 12, and the return pipe 14 is connected with the water tank 15, so that the cooling water with heat enters the water tank 15 for cooling. When cooling is required, the water in the water tank 15 is pumped out into the water inlet pipe 9 by starting the water pump 16 for cooling. By recycling the cooling water, energy can be saved and the water supply can be reduced, thereby improving the energy efficiency of the system. After long-term use, the cooling water in the water tank 15 gradually becomes hot, and the heat dissipation tube 18 is set to copper so that the heat dissipation tube 18 is opened to absorb heat, and then the heat dissipation tube 18 is cooled.

The fan 22 is started by a preset program, and the blowing end of the fan 22 is adapted to the vent 23, so that the hot air inside the heat sink 18 is discharged through the vent 23, thereby forming heat exchange with the external air, thereby increasing the heat exchange rate between the cooling water and the external air, and taking away the temperature of the cooling water through the flowing air, so that the cooling water in the water tank 15 dissipates heat quickly, and then by starting the fan 24, the fan 24 can draw the external air into the heat sink 19, further improving the heat exchange efficiency.

[0046] Working principle: The high-temperature sand is lifted to the top of the discharge barrel 3 by the lifting machine body, and then the high-temperature sand is poured into the discharge barrel 3, and the high-temperature sand will enter the interior of the square warehouse 4 by gravity. At this time, the cooling water is transported to the water inlet pipe 9, so that the cooling water enters the cooling pipe 10 to absorb the heat emitted by the high-temperature sand. The cooling water flows inside the cavity, thereby absorbing the temperature of the high-temperature sand. When the air cooler is started to allow external air to enter the air cooler, the air cooler blows the high-temperature sand moving on the top of the square warehouse 4. The blowing action of the air cooler can slow down the sliding speed of the sand to a certain extent, so that the sand can be more evenly distributed in the square warehouse 4. By folding the square warehouse 4, the flow path length of the high-temperature sand in the square warehouse 4 can be increased, thereby extending the contact time between the sand and the cooling water.

[0047] The cooling water that has absorbed the heat enters the water outlet pipe 13 through the cooling pipe 10, and the cooling water is continuously moved downward into the return pipe 14 through the connecting pipe 12. The return pipe 14 is connected to the water tank 15, so that the cooling water with heat enters the water tank 15 for cooling. When cooling is required, the water in the water tank 15 is pumped out into the water inlet pipe 9 by starting the water pump 16. By recycling the cooling water, energy can be saved and the water supply can be reduced. The heat is transported to the heat dissipation box 19 through the heat dissipation tube 18, and then the blowing end of the fan 22 is matched with the ventilation hole 23, so that the hot air inside the heat dissipation tube 18 is discharged through the ventilation hole 23, thereby forming heat exchange with the external air.
