Description

Technical Field

[0001] The utility model relates to the technical field of peripheral protection and rapid cooling of a rotary hydrogen crushing furnace, and particularly relates to a peripheral protection and rapid cooling device for a rotary hydrogen crushing furnace. Background Technique

[0002] A rotary hydrogen crushing furnace is a device used for processing rare earth magnetic alloys, and its functions and advantages include: improving production efficiency, improving magnet performance, reducing grinding time, reducing oxygen content, reducing sintering temperature, improving corrosion resistance, and controlling the particle size, shape and size distribution of powders.

[0003] A rapid cooling device for a rotary hydrogen crushing furnace disclosed in the Chinese utility model patent application publication specification CN206215917U includes a base, a water collecting tank and a water spraying pipe. The water collecting tank is a hollow semi-cylindrical body, the water collecting tank is installed on the base with the opening facing upwards, a water outlet is arranged at the bottom of the water collecting tank, the water spraying pipe is horizontally fixed above the water collecting tank, one end of the water spraying pipe is closed and the other end is provided with a water inlet, and more than one water spraying port is arranged at intervals along the length direction of the water spraying pipe. The beneficial effects of the utility model are as follows: after the hydrogen crushing of the hydrogen crushing furnace is completed, the outer shell is opened, the cooling device can be moved below the furnace core, and the furnace core is cooled by an external water pump. The water spraying ports can directly spray water towards the furnace core, the cooling is rapid, and the falling water stays in the water collecting tank and can be recycled again, saving water resources. Although the above device can cool the furnace core by spraying water when the furnace core needs to be cooled and recycle the cooled water, directly cooling the furnace core with water by the above device may directly cause the temperature of the furnace core to drop suddenly in a short time, which may damage the furnace core. Secondly, the use of the above device requires workers to stay near the furnace core all the time. Once the furnace core needs to be cooled, the workers need to immediately push the above device to the position of the furnace core for cooling, and the position of the furnace core is too hot, and the workers staying nearby for a long time may cause heat stroke. Then, the workers need to drag the above device to below the furnace core and spray water onto the surface of the furnace core for cooling, and the water droplets or water vapor splashed back when the just-sprayed water meets the high temperature may cause harm to the workers, there are certain safety hazards. Therefore, the present application provides a peripheral protection and rapid cooling device for a rotary hydrogen crushing furnace to meet the requirements. Content of the Utility Model

Since this device cools the gas around the furnace core by spraying cold air, the temperature around the furnace core and around the protection plate of this device is reduced to a certain extent. This prevents workers from suffering heat stroke when standing around the device to observe the cooling effect of the furnace core due to the high temperature around the furnace core.

[0017] An ice storage box is provided to place a sufficient amount of ice, and a cold air transmission fan is used to send cold air into the cold air shunt pipe. Then, the cold air is directly transmitted to the protection plate through the cold air shunt pipe and sent out through the A cooling holes to cool the furnace core. Since this device cools the air around the furnace core by spraying cold air through the A cooling holes on the protection plate, there will be no situation where water is directly sprayed on the furnace core and workers are scalded by the splashed water droplets or water vapor. At the same time, this device has a protection plate, and workers only need to observe the cooling situation of the furnace core on the back of the protection plate, no longer need to observe at a close distance to the furnace core, which greatly ensures the safety of workers.
