Description

Technical Field

[0001] The utility model belongs to the technical field of ferrosilicon cooling, and in particular relates to a cooling device used after smelting of metallic silicon. Background Art

[0002] After smelting, silicon and iron form metallic ferrosilicon. After the ferrosilicon is initially cooled and shaped in the mold, it needs to be thoroughly cooled. In the existing cooling scheme, such as patent application No. 202320217310.3, a ferrosilicon smelting furnace cooling device is disclosed, including rollers, a frame and a fan, etc. By placing the smelted ferrosilicon on rollers and blowing air from a cold blow pipe, the high-temperature ferrosilicon can be quickly cooled and dissipated, ensuring that subsequent processes can be carried out in a timely manner, thereby improving its production efficiency.

[0003] Although the above cooling scheme for ferrosilicon can achieve the cooling effect, it has the following defects during use: first, the method of using the rotation of rollers to drive the movement of ferrosilicon, the area between the upper side of the roller and the ferrosilicon is relatively narrow, and the rollers themselves will block the gas, resulting in poor gas flow in this area, making it inconvenient to directly discharge the hot air flow, so that the ferrosilicon can only be cooled by the cooling air flow when it is between the two rollers, thereby reducing the cooling efficiency of the ferrosilicon; secondly, a cold blow pipe is used to blow air between the two rollers, resulting in the air flow only being able to blow upward to the lower part of the ferrosilicon, resulting in poor cooling effect on the upper part of the ferrosilicon, so that the time required for the ferrosilicon to be completely cooled is longer, further reducing the cooling efficiency of the ferrosilicon. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a cooling device for use after smelting metallic silicon. Through the supporting mechanism, the ferrosilicon located in the area above the supporting rod can also be cooled normally, thereby improving the cooling efficiency of the ferrosilicon. The cooling mechanism is used to blow air to the upper and lower parts of the ferrosilicon, thereby shortening the time required for complete cooling of the ferrosilicon and further improving the cooling efficiency.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A cooling device for post-smelting metal silicon comprises a frame, a material supporting mechanism is arranged inside the frame, and a cooling mechanism is arranged outside the frame;

[0007] Supporting mechanism: a plurality of equally spaced rotating shafts are rotatably connected in the frame, two mounting plates 1 are fixedly sleeved on the rotating shafts, a supporting rod is fixedly connected between adjacent surfaces of the two mounting plates 1, the supporting rods are multiple and circumferentially distributed, and there are equally spaced gaps between the multiple supporting rods;

[0008] Cooling mechanism: a fan is fixedly connected to the top of the frame, an air distribution duct is fixedly connected to the frame, the air distribution duct is U-shaped, the air outlet of the fan is connected to the air distribution duct, one end of the air distribution duct is located above the frame, and the other end of the air distribution duct is located below the frame, both ends of the air distribution duct are connected to a delivery pipe, a plurality of equidistantly arranged nozzles are fixedly connected to the upper and lower sides of the frame, the nozzles on the upper side and the nozzles on the lower side of the frame are respectively connected to the delivery pipe, and the air outlet end of the nozzle is located on the inner side of the frame and is trumpet-shaped.

[0009] Furthermore, an air collecting duct is fixedly connected to the frame, and the shape of the air collecting duct is U-shaped. The top of the air collecting duct is connected to an air outlet duct, and the two ends of the air collecting duct are respectively located on both sides of the frame and are connected to an air inlet duct. The upper part of the air inlet duct is connected to a plurality of equidistantly arranged branch pipes, and the branch pipes extend into the frame away from the end of the air inlet duct.

[0010] Furthermore, a fixing rod is fixedly connected to the side surface of the supporting rod, and an end of the fixing rod away from the supporting rod is fixedly connected to the rotating shaft.

[0011] Furthermore, a second mounting plate is fixedly connected to the side of the frame, a reduction motor is fixedly connected to the second mounting plate, an output shaft of the reduction motor is fixedly sleeved with a main sprocket, one end of the rotating shaft extends out of the frame and is fixedly sleeved with a slave sprocket, and the main sprocket and the slave sprocket are connected by a chain transmission.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The supporting mechanism is used to replace the rollers in the original solution to move the ferrosilicon, so that the gap between the supporting rods can directly discharge the hot air flow in this area, accelerate the gas flow in this area, so that the ferrosilicon located above the supporting rods can also be cooled normally, thereby improving the cooling efficiency of the ferrosilicon. The cooling mechanism is used to provide nozzles on both the upper and lower sides of the frame, and the air flow from the nozzles can blow air to the upper and lower parts of the ferrosilicon, thereby shortening the time required for complete cooling of the ferrosilicon and further improving the cooling efficiency.

[0014] 2. Through the air collecting duct, air outlet duct, air inlet duct and branch duct, part of the hot air flow in the rack is discharged away from the rack by the air outlet duct, reducing the hot air flow near the rack, thereby reducing the temperature of the air flow inhaled by the fan, and further accelerating the cooling efficiency of ferrosilicon.

[0015] 3. The firmness of the support rod is improved by fixing the rod. By installing the reduction motor on the second mounting plate, compared with the original motor being located inside the frame, the high temperature to which the reduction motor is subjected can be reduced, thereby avoiding the reduction motor from being damaged by high temperature.

[0027] Cooling mechanism: A fan 5 is fixedly connected to the top of the frame 1, and an air distribution duct 6 is fixedly connected to the frame 1. The shape of the air distribution duct 6 is U-shaped, and the air outlet of the fan 5 is connected to the air distribution duct 6. One end of the air distribution duct 6 is located above the frame 1, and the other end of the air distribution duct 6 is located below the frame 1. Both ends of the air distribution duct 6 are connected to a delivery pipe 7. The upper and lower sides of the frame 1 are fixedly connected with a plurality of equidistantly arranged blowing nozzles 8. The blowing nozzles 8 on the upper side of the frame 1 and the blowing nozzles 8 on the lower side are respectively connected to the delivery pipe 7. The air outlet end of the blowing nozzle 8 is located on the inner side of the frame 1 and is trumpet-shaped.

[0028] An air collecting duct 9 is fixedly connected to the frame 1, and the shape of the air collecting duct 9 is U-shaped. The top of the air collecting duct 9 is connected to an air outlet duct 10. The two ends of the air collecting duct 9 are respectively located on both sides of the frame 1 and are connected to an air inlet duct 11. The upper part of the air inlet duct 11 is connected to a plurality of equally spaced branch pipes 12, and the branch pipes 12 extend into the frame 1 away from the end of the air inlet pipe 11.

[0029] A fixing rod 13 is fixedly connected to the side surface of the supporting rod 4 , and an end of the fixing rod 13 away from the supporting rod 4 is fixedly connected to the rotating shaft 2 .

At the same time, the fan 5 blows the cold air from the air distribution duct 6 to the two conveying pipes 7, and then sprays it from the blowing nozzles 8 on the upper and lower sides. The airflow entering the frame 1 cools down the upper and lower parts of the ferrosilicon, and the hot air flow at the narrow gap between the ferrosilicon and the support rod 4 will flow from the gap between the support rods 4. Part of the hot air in the frame 1 enters the air inlet pipe 11 from the branch pipe 12, and then converges to the air gathering pipe 9 and is discharged from the air outlet pipe 10 to the factory building until the ferrosilicon slowly moves to the other end of the frame 1 to complete the cooling work.
