Abstract

The invention discloses a device capable of recycling waste heat of a neodymium iron boron waste roasting kiln, and relates to the technical field of neodymium iron boron rare earth materials. The device comprises a roaster, a regulating valve, a material partition plate, a preheating bin, a feeding hopper, a synchronous gear, a bias elastic piece and a heat insulation plate. According to the device, the waste heat is introduced into the preheating bin to preheat neodymium iron boron waste, in the process, whenever the neodymium iron boron waste is added to the preheating bin, the heat insulation plate can open the feeding hopper in time as the neodymium iron boron waste is added, and close the feeding hopper when no neodymium iron boron waste is added, waste heat loss is reduced, the waste heat utilization is enhanced, in addition, the heat insulation plate is conical after opened, so that the neodymium iron boron waste can be divided and scattered on the two sides of the preheating bin, expanding of a contact area of the neodymium iron boron waste and the waste heat is facilitated, and sufficient utilization of the waste heat is further enhanced.

Description

technical field [0001] The invention relates to the technical field of neodymium-iron-boron rare-earth materials, in particular to a device capable of recycling waste heat from roasting kilns with neodymium-iron-boron waste. Background technique [0002] NdFeB is a kind of magnet, which has excellent magnetic properties, extremely high magnetic energy product and coercive force, and also has the advantages of high energy density, its own excellent machining performance, and its working temperature can reach 200 ℃. And the texture is hard, and it has been widely used in modern industry and electronic technology, which makes the miniaturization and light weight of instruments, motors, magnetic separation and magnetization and other equipment realized. [0003] The production process of NdFeB generally includes the steps of preparing raw materials, smelting, casting, hydrogen crushing, magnetic field orientation and pressing, sintering, and post-processing. In the above product...
