Embodiment

[0074] see figure 1 , The present invention provides an automatic crushing device for NdFeB magnetic powder block, which is used for screening and crushing NdFeB magnetic powder block formed by NdFeB magnetic powder, so as to form magnetic powder in the same particle size range. Wherein, the NdFeB magnetic block automatic crushing device includes a vibration dispersion mechanism, a crushing mechanism, a blast recovery mechanism, a screening and collection mechanism, a crushing mechanism, a detection mechanism and a controller.

[0075] The vibration dispersing mechanism includes a dispersing cylinder 1 , a screen one 2 and a vibration source 3 . The screen one 2 is installed in the dispersing cylinder 1, and is used to screen the NdFeB magnetic powder blocks input from the outside. The vibration source 3 is installed on the dispersion shell 1, and is used to vibrate the screen one 2. In this embodiment, the dispersing cylinder 1 is a cylinder, both ends of which are open end...

Embodiment 2

[0087] see figure 2 , this embodiment provides an automatic crushing device for NdFeB magnetic powder blocks, which adds an electromagnet 17 on the basis of Embodiment 1. There are multiple electromagnets 17, and the electromagnets 17 belong to the blowing recovery mechanism. The electromagnet 17 is installed on the outer wall of the recovery housing 7 . The controller is also used to start the electromagnet 17 at intervals of a preset time, so that the magnetism generated by the electromagnet 17 will absorb the magnetic powder of the recovery housing 7 on the inner wall of the recovery housing 7, and during the working time of the electromagnet 17 Close electromagnet 17 when reaching a preset time two.

[0088] Therefore, in the NdFeB magnetic block automatic crushing device provided in this embodiment, the electromagnet 17 of the blower recovery mechanism can generate a magnetic field effect on the magnetic powder in the recovery housing 7, so that the magnetic powder is ...

Embodiment 3

[0090] see Figure 3-7 , This embodiment provides an automatic crushing device for NdFeB magnetic powder blocks, which adds a conveying mechanism on the basis of Embodiment 1. The conveying mechanism is used to convey the NdFeB magnetic powder blocks rolled out from the outlet one 15 to the screen one 2 . Among them, the controller drives the conveying mechanism to convey the NdFeB magnetic powder blocks once every three preset times.

[0091] The conveying mechanism in this embodiment includes a lifting bucket 19, a lifting component, an electromagnetic adsorption block 20, a material transfer component and a material feeding component. The lifting bucket 19 is located on one side of the crushing shell 12, and receives the NdFeB magnetic powder blocks rolled out from the outlet one 15. A discharge port 36 is provided on the side wall of the lifting barrel 19, and the height of the discharge port 36 is higher than that of the dispersion cylinder 1 . The lifting assembly is ...

Abstract

The invention discloses an automatic crushing device for neodymium-iron-boron magnetic powder blocks, and a crushing method of the automatic crushing device. The automatic crushing device comprises avibratory dispersing mechanism, a mincing mechanism, a blown air recycling mechanism, a screening and collecting mechanism, a crushing mechanism, a detecting mechanism and a controller. According to the automatic crushing device disclosed by the invention, the vibratory dispersing mechanism is used for implementing vibratory screening on the neodymium-iron-boron magnetic powder blocks; the mincingmechanism is used for mincing the neodymium-iron-boron magnetic powder blocks which are subjected to vibratory screening; the blown air recycling mechanism is used for blowing magnetic powder into arecycling housing so that the magnetic powder can be recycled; while small powder clumps and some magnetic powder fall onto a screen to be screened; the small powder clumps roll from the screen into acrushing housing; the magnetic powder directly falls into a collection bucket; the small powder clumps are further fragmented under rolling of a rolling wheel unit; meanwhile some large magnetic blocks are also crushed; and the magnetic powder falls onto a conveying component and are conveyed into the collection bucket. The automatic crushing device disclosed by the invention can improve the crushing and screening efficiency, can also increase the utilization rate of a magnetic material, improves the crushing effect on the neodymium-iron-boron magnetic powder blocks and realizes full-automatic circulation.

Description

technical field [0001] The invention relates to an automatic crushing device in the field of crushing technology, in particular to an automatic crushing device for NdFeB magnetic powder blocks, and also relates to an automatic crushing method for NdFeB magnetic powder blocks of the device. Background technique [0002] NdFeB magnets are tetragonal crystals formed of neodymium, iron and boron. This kind of magnet is the second most magnetic permanent magnet after the absolute zero holmium magnet, and it is also the most commonly used rare earth magnet. NdFeB magnets are widely used in electronic products, such as hard drives, mobile phones, earphones, and battery-powered tools. NdFeB is divided into sintered NdFeB and bonded NdFeB. Bonded NdFeB is magnetic in all directions and is corrosion-resistant; and sintered NdFeB is easy to corrode, and the surface needs to be coated. Generally, there are galvanized, Nickel, environment-friendly zinc, environment-friendly nickel, nic...
