Embodiment 1

[0031] refer to Figure 1-7 , a cleaning and screening equipment for NdFeB waste recycling, comprising a bottom plate 1, a side plate 2 is fixedly installed on one side of the upper surface of the bottom plate 1, and a first fixed plate 3 is fixedly installed on the inner surface of the upper part of the side plate 2, and the first fixed plate 3 is fixedly installed with a mixing bucket 4, and the side plate 2 above the first fixing plate 3 is fixedly provided with a second fixing plate 5, and a motor 6 corresponding to the mixing bucket 4 is fixedly installed on the second fixing plate 5, and the motor 6 After the output shaft passes through the second fixed plate 5, it is fixedly connected with the stirring shaft 7, and the stirring shaft 7 extends downwards into the mixing bucket 4, and the surface of the stirring shaft 7 is fixed with several groups of blades 8 along the length direction, and the mixing bucket 4. A first discharge pipe 10 is fixedly connected to the bottom...

Embodiment 2

[0044] refer to Figure 1-2 , as another preferred embodiment of the present invention, the difference from Embodiment 1 is that the drainage mechanism includes a horizontal plate 20, a vertical plate 21, and an inclined plate 22, and a screen corresponding to the screening box 19 is provided directly below the second discharge pipe 16. The inclined plate 22, the lower surface of the inclined plate 22 is fixedly provided with a vertical plate 21, and the bottom end of the vertical plate 21 is fixedly equipped with a horizontal plate 20, and the horizontal plate 20 is fixedly installed on the screening box 19. The bottom end of the second discharge pipe 16 is covered with a nozzle 17 .

[0045] By setting the drainage mechanism, the dirty water flowing out of the screening bucket 12 can be more evenly introduced into the screening box 19, so that the contact between the conveyor belt 28 and the dirty water is more uniform and effective, and then the coating on the conveyor belt...

Abstract

The present invention relates to the technical field of recycling NdFeB waste, in particular to a cleaning and screening method and equipment for recycling NdFeB waste. The opening at the bottom of the mixing tank is fixedly connected with a first discharge pipe through a valve. A third fixed plate is fixed on the side plate below the fixed plate, and a screening bucket corresponding to the mixing bucket is fixedly installed on the third fixed plate, and a screening mechanism is arranged on the top of the screening bucket. The bottom of the screening bucket is fixed with a second discharge pipe, the other side of the upper surface of the bottom plate is fixed with a support plate, and the top of the support plate is fixed with a diversion box, and the diversion box is connected with the second discharge pipe. A drainage mechanism is arranged between them, and a corresponding screening module is arranged on the diversion box. The invention has the advantage of more sufficient recovery of NdFeB waste materials.

Description

technical field [0001] The invention relates to the technical field of recycling NdFeB waste materials, in particular to a cleaning and screening method and equipment for recycling NdFeB waste materials. Background technique [0002] Neodymium iron boron, simply speaking, is a kind of magnet. The difference from the magnets we usually see is that it is called the "magnet king" because of its excellent magnetic properties. NdFeB contains a large amount of rare earth elements neodymium, iron and boron, and its characteristics are hard and brittle. As a kind of rare earth permanent magnet material, NdFeB has extremely high magnetic energy product and coercive force. At the same time, the advantages of high energy density make NdFeB permanent magnet materials widely used in modern industry and electronic technology, so that the instrument Miniaturization, light weight and thinning of equipment such as instruments, electroacoustic motors, and magnetic separation and magnetizatio...
