Problems solved by technology

However, the existing filtering devices for recycling rare earth wastes usually do not have a graded screening structure, so that the graded filtration of rare earth wastes cannot be realized, and metal particles of different particle sizes in rare earth wastes cannot be sieved, so the design here A filter device for NdFeB waste recycling is developed to solve the above problems

Embodiment 1

[0021] see Figure 1-3 , the present embodiment provides a filter device for recycling NdFeB waste, including a treatment cylinder 1 and a filter mechanism 2, the edge of the bottom surface of the treatment cylinder 1 is vertically provided with several support legs 12, which are supported by the support legs 12 The entire processing cylinder 1, the interior of the processing cylinder 1 is a hollow structure, and the top opening is provided with a wide-mouthed feeding hopper 11, through which waste materials can be put into the processing cylinder 1, so that the filtering mechanism 2 to carry out the filtering operation, the filtering mechanism 2 is arranged inside the processing cylinder 1, the filtering mode of the traditional rare earth waste recovery and filtering device is changed, and the filtering mechanism 2 is used to realize the graded screening structure, which can realize the graded filtration of the rare earth waste, and can remove the rare earth waste Metal parti...

Embodiment 2

[0029] see Figure 1-3 , further improvements have been made on the basis of Example 1:

[0030] In order to solve the problem of how to avoid the sieving holes of the first umbrella filter screen 18, the second umbrella filter screen 19 and the third umbrella filter screen 110 from being blocked, the primary receiving cylinder 24, the secondary receiving cylinder 25 and the The inner top opening of the three-stage receiving tube 26 is provided with an umbrella-shaped filter cover 17 sidewalls flush with each other for cleaning rods 27, and the side walls of the three cleaning rods 27 are provided for cleaning the first umbrella-shaped filter screen 18 respectively. , the cleaning brush 28 of the second umbrella-shaped filter screen 19 and the third umbrella-shaped filter screen 110, by setting the cleaning brush 28, when the umbrella-shaped filter cover 17 rotates with the transmission rod 14, the first umbrella-shaped filter screen can be made 18. The second umbrella-shaped...

Abstract

The invention discloses a filtering device for neodymium iron boron waste recovery, and relates to the technical field of neodymium iron boron production, the filtering device comprises a treatment barrel and a filtering mechanism, a plurality of supporting legs are vertically arranged at the edge position of the bottom end face of the treatment barrel, the interior of the treatment barrel is of a hollow structure, and a wide-mouth feeding hopper is arranged at an opening in the top end of the treatment barrel. The filtering mechanism is arranged in the treatment barrel. According to the filtering device for neodymium iron boron waste recovery, the filtering mode of a traditional rare earth waste recovery filtering device is changed, a graded screening structure is achieved through the filtering mechanism, graded filtering of rare earth waste can be achieved, and metal particles with different particle sizes in the rare earth waste can be effectively screened.

Description

technical field [0001] The invention relates to the technical field of NdFeB production, in particular to a filter device for recycling NdFeB waste. Background technique [0002] 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 magnetization become possible. [0003] In the production process of NdFeB, in order to improve the utilization rate of NdFeB, it is necessary to filter the waste produced to realize the recycling of NdFeB. However, the existing filtering devices for recycling rare earth wastes usually do not have a graded screening structure, so that the graded filtration of rare earth wastes canno...
