Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a cooling device for high-temperature calcined coke in a carbon rotary kiln. Background Art

[0002] The existing carbon rotary kiln high temperature calcined coke cooling device is used to cool the petroleum coke after high temperature calcination in the carbon rotary kiln. Its purpose is to ensure that the petroleum coke can be processed at a safe temperature and achieve the required physical and chemical properties.

[0003] However, the existing cooling device for high-temperature calcined coke in carbon rotary kilns is unable to separate particles of different sizes within the petroleum coke during use. Since petroleum coke of different particle sizes is mixed together for air cooling, their surface areas and masses are different, resulting in uneven cooling rates. Smaller particles may cool too quickly, while larger particles may still retain a certain amount of heat inside. This uneven heat distribution may lead to temperature differences in different parts of the petroleum coke, thereby affecting the final cooling rate. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide a cooling device for high-temperature calcined coke in a carbon rotary kiln. The arranged screen can separate particles of different sizes in the petroleum coke, with the larger ones remaining on the screen and the smaller ones falling on the supporting net. After the particles of different sizes are separated into two parts, the density of each part is relatively uniform. During the air cooling process, the heat transfer rate of the surfaces of particles with similar density is relatively uniform, and the cooling rate will not be reduced due to the density difference. This can ensure that the entire cooling process is more uniform and effective, improve the cooling efficiency and the quality stability of the product, and the fan blades arranged can blow air upward to cool the petroleum coke. While blowing air, the electric push rod can drive the screen and the supporting net to move repeatedly, which can maintain the dispersion state between the particles, so that the petroleum coke particles can more evenly contact the air blown out by the fan blades, thereby increasing the uniformity and efficiency of the overall cooling effect.

[0005] The cam is connected to the bottom surface of the box body by a fan, and the fan is connected to the bottom surface of the box body by a fan.

[0006] According to the cooling device for high-temperature calcined coke in a carbon rotary kiln described in the utility model, a handle is fixedly connected to the front surface of the sealing cover, and an anti-slip pad is fixedly connected to the outer surface of the handle.

[0007] According to the cooling device for high-temperature calcined coke in a carbon rotary kiln described in the utility model, the upper surface of the feed hopper is movably connected with a cover plate, and a clamping groove is provided on the cover plate.

[0008] According to the cooling device for high-temperature calcined coke in a carbon rotary kiln described in the utility model, an elastic clip is fixedly connected to the side surface of the feed hopper, and the elastic clip is movably connected to the clip groove.

[0009] According to the cooling device for high-temperature calcined coke in a carbon rotary kiln described in the utility model, the lower surface of the box body is fixedly connected to support legs, and the side surfaces of the support legs are fixedly connected to connecting rods.

[0013] Beneficial effects

[0014] 1. Compared with the existing technology, the cooling device for high-temperature calcined coke in the carbon rotary kiln can separate particles of different sizes in the petroleum coke through the provided screen. The larger ones remain on the screen and the smaller ones fall on the supporting net. After the particles of different sizes are separated into two parts, the density of each part is relatively uniform. During the air cooling process, the heat transfer rate of the particles with similar density is relatively uniform, and the cooling rate will not be reduced due to density differences. This can ensure that the entire cooling process is more uniform and effective, thereby improving the cooling efficiency and product quality stability.

[0015] 2. Compared with the existing technology, the cooling device for high-temperature calcined coke in the carbon rotary kiln can blow air upward through the fan blades to cool the petroleum coke. While blowing air, the electric push rod can drive the screen and the carrier net to move repeatedly, which can maintain the dispersion state between the particles, so that the petroleum coke particles can be more evenly exposed to the air blown by the fan blades, thereby increasing the uniformity and efficiency of the overall cooling effect.
