Description

TECHNICAL FIELD

[0001] The present application relates to the field of neodymium iron boron waste cleaning equipment, and particularly relates to a neodymium iron boron waste cleaning device. BACKGROUND

[0002] Neodymium iron boron is a very important permanent magnet alloy material, has the characteristics of good magnetic performance and excellent temperature resistance, and is widely used in new energy vehicles, wind power generation, electronic products and other fields. However, a large amount of waste will be generated in the production process of neodymium iron boron, and the surface of the waste will adhere to oil stains, iron filings, dust and other pollutants. In order to recycle the neodymium iron boron components in the waste, the waste needs to be thoroughly cleaned first.

[0003] At present, the common cleaning method of neodymium iron boron waste is to pour the waste liquid into a roller, use the high-speed rotation of the roller to drive the waste to tumble, make the waste fully dispersed, and then spray a large amount of clean water from the top of the roller to wash the waste, so as to wash off the surface pollutants. This method has two problems: first, the noise emitted by the high-speed rotation of the roller is large, which affects the operating environment; second, the large amount of water spraying method uses too much water, which is easy to cause waste of water resources. Therefore, it is necessary to develop a new cleaning process for neodymium iron boron waste to reduce energy consumption and pollution.

[0004] Therefore, based on some of the above prior art, the present application has been further designed and improved. SUMMARY

[0005] In order to solve the problems in the prior art, the present application provides a neodymium iron boron waste cleaning device to solve the problems of noise and excessive water consumption in the prior art.

[0006] The technical scheme of the present application is as follows:

The inner cover plate 30 is provided with a plurality of through grooves 34 for the wall plates 22 to pass through.

[0036] Specifically, the lower surface of the inner cover plate 30 is in the shape of an inverted circular truncated cone that is adapted to the shape of the bottom of the inner cylinder 20, and the lower surface of the inner cover plate 30 is a positive adsorption structure 31. After cleaning, the neodymium iron boron waste can be adsorbed below the inner cover plate 30 and taken out of the inner cylinder 20 by the positive adsorption structure 31, which is more convenient and faster than manual cleaning.
