Description

Technical Field

[0001] The utility model relates to the technical field of slag discharge of furnace slag coolers, in particular to a slag discharge device for a slag discharge port of a furnace slag cooler. Background Art

[0002] The furnace slag cooler is a device used to cool and transport slag, usually used in the high-temperature slag treatment process in the fields of metallurgy, electric power, chemical industry, etc. Its main function is to quickly cool the high-temperature slag to a suitable temperature and particle size for subsequent processing and utilization. At the same time, the slag cooler also has the function of transporting slag to a designated location. Among them, the slag discharge device at the slag discharge port of the furnace slag cooler is a key component of the slag cooler system, which is mainly used to control and discharge the high-temperature slag discharged from the furnace to ensure that the slag can be safely and effectively discharged from the slag cooler. Therefore, in the process of coal energy utilization, the furnace slag cooler, as an important auxiliary machine of the circulating fluidized bed boiler, undertakes the selective discharge and cooling functions of the slag.

[0003] However, in the traditional slag discharge method, the slag is not cooled well due to the short transportation distance and time during the slag transportation process, which causes the slag to cool and solidify together easily during the transportation process, causing the slag discharge pipe to be blocked, affecting the continuity and stability of the slag discharge. For this reason, we propose a slag discharge device for the slag discharge port of the furnace cooler. Utility Model Content

[0025] A cooling device 15, which is arranged at the top of the inner cavity of the support frame 1 and is used to cool the slag;

[0026] The slag conveying device 16 is arranged in the inner cavity of the support frame 1 and is used to convey the slag and prolong the conveying time of the slag from the slag inlet 3 to the slag outlet 4.

[0027] Furthermore, the slag delivery device 16 includes a main shaft 9 and a slag delivery plate 10. The main shaft 9 is fixedly connected to the rotating shaft of the motor gear box 5. The main shaft 9 extends into the inner cavity of the slag discharge box 2 and is rotatably connected to the inner walls on both sides of the slag discharge box 2. The slag delivery plate 10 is fixedly connected to the side of the slag discharge box 2.

[0028] Furthermore, the slag feeding plate 10 is spirally wound and connected to the side of the main shaft 9 , and the side of the slag feeding plate 10 close to the motor gear box 5 is a rough surface, and the two ends of the slag feeding plate 10 are respectively close to the inner walls of the slag discharge box 2 on both sides.

[0029] Furthermore, the cooling device 15 includes a heat dissipation installation shell 12, a water pipe 13 and a booster water pump 17. The heat dissipation installation shell 12 is fixedly connected to the inner wall of the top side of the slag discharge box 2. The inner cavity of the heat dissipation installation shell 12 is hollow. The water pipe 13 is fixedly connected to the inner cavity of the heat dissipation installation shell 12. The lower end of the water inlet 8 extends to the inner cavity of the heat dissipation installation shell 12 and is fixedly connected to the booster water pump 17.

[0030] Furthermore, the lower end of the booster water pump 17 is fixedly connected to the water pipe 13, and the lower end of the water pipe 13 is fixedly connected to three pipes perpendicular to it. Both ends of the pipes are fixedly connected to sprinkler heads, and the lower surface of the heat dissipation mounting shell 12 corresponds to the lower side of the vertical pipes and is provided with a plurality of through grooves.

[0032] Working principle: When the furnace slag cooler starts working, the slag enters the slag discharge box 2 from the slag inlet 3, the drive motor 6 is started, and the main shaft 9 starts to rotate through the motor gear box 5. The rotation of the main shaft 9 drives the slag delivery plate 10 to start working. The spiral shape design of the slag delivery plate 10 enables it to effectively transport the slag from the slag inlet 3 to the slag outlet 4. Since the surface of the slag delivery plate 10 is rough, it increases the friction with the slag, thereby ensuring that the slag can be effectively pushed and transported. During the slag transportation process, the blower 7 starts working and sends cold air into the heat dissipation installation shell 12 through the air inlet 11. At the same time, the cooling device 15 also starts working, and the cooling water is sent into the water pipe 13 through the water inlet 8 through the booster water pump 17, and then passes through the nozzle on the pipeline. The sprinkler head forms water mist, and under the synergistic effect of the cold wind, the cold wind mixed with water mist flows through the air outlet 14 in the slag discharge box 2, which preliminarily cools the slag and helps prevent the slag from becoming cold and solidified due to uneven cooling during transportation. During the whole process, the continuous rotation of the slag feeding plate 10 ensures that the slag can be continuously and stably transported from the slag inlet 3 to the slag outlet 4, thereby extending the transportation distance and time of the slag in the device and increasing the cooling effect. At the same time, the cold air with water mist effectively cools the slag during transportation, avoiding the blockage and solidification problems of the slag.
