Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a coke drying device. Background Technology

[0002] Coke is a solid fuel obtained by dry distillation of coal at a high temperature of approximately 1000℃. During coke production, a step involves physically cooling the high-temperature coke. A common method is wet quenching, which involves spraying cooling water onto the coke to achieve cooling. However, this method leaves a large amount of moisture in the coke, necessitating drying to remove this remaining moisture. Common coke drying equipment includes a drying chamber equipped with a conveyor belt or guide plate, allowing for simultaneous conveying and drying of the coke. However, guide plates tend to cause coke to escape quickly from the drying chamber, resulting in poor drying efficiency. While conveyor belts can control the speed of coke transport within the drying chamber, they are expensive and difficult to maintain. Furthermore, when coke falls onto the conveyor belt, it forms piles, which can lead to uneven heating. All these factors significantly complicate the coke drying process. Utility Model Content

[0021] The material guiding assembly includes a conical material guiding cap 3 and an annular material guiding disc 4. The material guiding cap 3 is located above the material guiding disc 4, and there is a gap between the two. The protruding tip of the material guiding cap 3 faces the center of the feed inlet, which is located at the center of the top of the drying chamber 1. The material guiding disc 4 has a constricted structure that is wider at the top and narrower at the bottom. The diameter of the upper edge of the material guiding disc 4 is the same as the inner diameter of the drying chamber 1, and its upper edge is fixed to the inner wall of the drying chamber 1. The diameter of the lower edge of the material guiding cap 3 is greater than the diameter of the lower opening of the material guiding disc 4 and smaller than the diameter of the upper opening of the material guiding disc 4.

[0022] The drying tube assembly includes a drying straight tube 5 and a drying ring tube 6. The drying straight tube 5 is placed horizontally in the drying chamber 1 along the front-to-back direction and passes through the guide cap 3. One end of the drying straight tube 5 extends to the outside of the drying chamber 1 and is connected to the drying equipment, which is a hot air blower. The drying ring tube 6 is arranged around the outside of the guide plate 4. One end of the drying ring tube 6 also extends to the side of the drying chamber 1 and is connected to the drying equipment. Several air nozzles 7 are provided on the drying straight tube 5, and several air holes 8 are provided on the drying ring tube 6.

[0023] The air nozzles on the drying straight pipe 5 are located on both sides of the lower part of its pipe wall, and the air holes on the drying ring pipe 6 are arranged facing the feed tray 4.

[0024] Several ventilation holes 9 are evenly distributed on the guide cap 3 and the guide plate 4.

[0025] One end of the drying straight pipe 5 located inside the drying chamber 1 is fixedly connected to the inner wall of the drying chamber 1.

At this time, the drying equipment is started, and the drying equipment generates hot air, which is sent into the interior of the drying chamber 1 through the drying straight pipe 5 and the drying ring pipe 6. The hot air causes the interior of the drying chamber 1 to heat up, and also heats up the guide cap 3 and the guide plate 4. After the coke enters the drying chamber 1, it first falls onto the top guide plate 3, where it scatters and slides down. Then, it falls onto the lower guide plate 4 along the surface of the guide plate 4. 4. Since the guide plate 4 has an annular constricted structure, its plate surface 4 is an inclined surface. The coke falling onto the guide plate 4 slides down along the opening at the lower end of the guide plate 4 onto the guide plate 3 of the next guide assembly. Then the coke slides down in the above-mentioned sliding manner. Multiple sets of guide assemblies can slow down the falling speed of the coke. In addition, the coke will continuously tumble when falling, so that all surfaces of the coke can fully contact the hot air, thereby improving the drying efficiency of the coke. The dried coke is discharged along the discharge port 2 at the bottom.
