Description
Technical Field
[0001] The utility model relates to the technical field of oil shale dry distillation, and more specifically to a material discharge port of a dry distillation furnace. Background Art
[0002] The shale distillation process uses shale from the open-pit mine, which enters the distillation furnace through a loader. It moves downward by its own gravity as the ash discharger operates continuously, causing the shale in the furnace to continuously drop. The oil shale running in the distillation furnace is heated by the hot gas provided by the heating furnace and the mixed gas produced by the generating section, and is dried, preheated and distilled from top to bottom. Finally, the shale ash is cooled and cooled in the water basin at the bottom of the distillation furnace, and is discharged out of the furnace by a gray iron shovel due to the rotation of the ash dish, and falls onto the belt conveyor through the discharge ports on both sides of the water basin.
[0003] The common discharge port of the retort furnace is divided into two parts, the upper and lower parts of the silo and the lower part, which are connected by the discharge port grate in the middle. The shale ash discharged from the retort furnace water basin first falls on the grate in the silo, and then enters the silo after being filtered and decelerated. However, the original retort furnace discharge port mostly adopts a 4-hole grate, and the specification of each hole is 60×40cm. Due to the large gap in the structure, it is easy for large pieces of shale ash or retort furnace refractory bricks and other materials discharged from the water basin to fall directly onto the belt below, causing the belt to overload or directly damage the belt and stop operating. It directly leads to production interruption and poses a safety hazard. In addition, since the discharge port is a fully enclosed structure, there is a large amount of water vapor generated by the water basin and dust generated by the falling shale ash. The internal environment is humid, which easily causes the shale ash to stick and block the discharge port grate. In addition, due to the low internal visibility, employees cannot find and clear it in time, resulting in the shutdown of a single retort furnace. Later, it takes a lot of time to clean up the materials accumulated in the discharge port due to blockage, which not only affects shale oil production, consumes manpower and material resources, but also poses a safety hazard. For this reason, we proposed a retort discharge port. Utility Model Content
