[0040] After processing NdFeB products, some waste materials will be generated. To save resources and reduce production costs, people usually recycle these waste materials. During the recycling process, first, the NdFeB waste materials need to be calcined to remove oil, water, and combustibles in the NdFeB waste materials.

[0041] In the related art, since the NdFeB waste materials are in blocks of different sizes, the contact area for calcination is large and the time consumption is long. At the same time, most of the NdFeB waste materials are mixed with mud, which will affect the calcination efficiency and the calcination is not sufficient.

[0042] To solve the problems in the related art to a certain extent, the embodiment of the present application provides a calcining furnace. When in use, only need to pour the waste materials into the feeding port of the box body 21, start the first motor 22, the output end of the first motor 22 drives the crushing roller 23 to rotate, and the rotating crushing roller 23 crushes the poured waste materials into small pieces, increasing the contact area for calcining the waste materials and accelerating the calcining speed of the waste materials. While crushing, the waste materials mixed with mud are washed by the washing component, improving the calcination efficiency. After crushing and washing, they are transported into the furnace body 11 through the conveyor belt 25, and the waste materials are stirred and calcined by the stirring component 13.

[0043] The present application will be described below in conjunction with the accompanying drawings and with reference to specific embodiments:

[0044] Combined Figures 1 - 3 , the embodiment of the present application provides a calcining furnace, including a calcining furnace body 1. The calcining furnace body 1 includes: a heater 12 is arranged inside the furnace body 11; a stirring component 13 is arranged on the furnace body 11; a processing component 2 is arranged outside the furnace body 11. The processing component 2 includes: a box body 21 is arranged outside the furnace body 11; a first motor 22 is arranged outside the box body 21; a crushing roller 23 is arranged at the output end of the first motor 22 and is located inside the box body 21; a conveyor belt 25 is arranged inside the box body 21 and is located below the crushing roller 23; a washing component 24 is arranged on the box body 21.

[0045] When in use, pour the waste materials into the feeding port of the box body 21, start the first motor 22, the output end of the first motor 22 drives the crushing roller 23 to rotate, and the rotating crushing roller 23 crushes the poured waste materials into small pieces, increasing the contact area for calcining the waste materials and accelerating the calcining speed of the waste materials. While crushing, the waste materials mixed with mud are washed by the washing component, improving the calcination efficiency. After crushing and washing, they are transported into the furnace body 11 through the conveyor belt 25, and the waste materials are stirred and calcined by the stirring component 13.

[0046] Specifically, the conveyor belt 25 is of the NN200 type. Its working principle is composed of a driving device that tightens the conveyor belt, a middle frame, and idlers. When the driving device operates, it drives the rotation of the rotating shaft, thereby driving the rotation of the idlers. The idlers drive the cyclic rotation of the conveyor belt through friction, thus achieving the transportation effect. The corresponding principle structure is not shown in the drawings for this section.

[0047] In some embodiments, the flushing assembly 24 includes: a water tank 241 disposed on one side of the box body 21; a spray head 242 disposed on one side of the water tank 241 and penetrating through the box body 21. The water source in the water tank 241 is sprayed through the spray head 242 to flush the waste poured into the box body 21.

[0048] In some embodiments, a water pump 27 is disposed on one side of the box body 21 to cooperate with the water tank 241. A water delivery pipe 271 is disposed on the water pump 27 and penetrates through the box body 21. When the water pump 27 is started, the flushing water flowing to the inner bottom of the box body 21 is pumped out through the water delivery pipe 271 and conveyed into the water tank 241, enabling the flushing water to be recycled and reducing the waste of water resources.

[0049] In some embodiments, drainage holes 251 are provided on the conveyor belt 25. When transporting waste, the water on the waste and the flushed water will fall from the drainage holes 251 on the conveyor belt 25 to the bottom of the box body 21, preventing the flushing water from being transported into the furnace body 11 by the conveyor belt 25 and affecting the roasting efficiency.

[0050] In some embodiments, a guide plate 28 is provided on the inner side wall of the furnace body 11 to cooperate with the conveyor belt 25 to guide the waste to a position where it can be stirred by the stirring assembly 13.

[0051] In some embodiments, a filter screen 26 is provided inside the box body 21 and is located below the conveyor belt 25. A sliding groove 261 is provided on the inner side wall of the box body 21 to cooperate with the filter screen 26, enabling the filter screen 26 to be slidably connected to the box body 21. The filter screen 26 filters out the sediment in the flushed water source, preventing the sediment from being sucked into the water pump 27 and causing damage to the water pump 27. At the same time, through the sliding groove 261, it is convenient to draw out the filter screen 26 to clean the sediment on the filter screen 26.

[0052] In some embodiments, the stirring assembly 13 includes: a second motor 131 disposed on the top of the furnace body 11; a stirring rod 132 disposed at the output end of the second motor 131 and penetrating through the furnace body 11. When the second motor 131 is started, the output end of the second motor 131 drives the stirring rod 132 to rotate, stirring the waste in the furnace body 11, preventing the waste in the furnace body 11 from accumulating together, and improving the roasting efficiency of the waste.

[0053] In some embodiments, a smoke exhaust port 14 is provided at the top of the furnace body 11, penetrating through the top of the furnace body 11, and the flue gas generated by waste roasting is discharged out of the furnace body 11 through the smoke exhaust port 14.

[0054] Specifically, the flue gas generated by material roasting is not directly discharged into the air, but is discharged into the device for treating flue gas. The corresponding principle structure is not drawn in the attached drawings for this section.
