Description

Technical Field

[0001] The utility model relates to the technical field of magnetic waste recycling, in particular to a recycling device for magnetic material grinding waste. Background Art

[0002] Magnetic materials are materials that respond in some way to magnetic fields. Depending on the strength of the magnetism they exhibit in an external magnetic field, they can be divided into diamagnetic, paramagnetic, ferromagnetic, antiferromagnetic, and ferrimagnetic materials. Most materials are diamagnetic or paramagnetic, and their response to external magnetic fields is relatively weak. Ferromagnetic and ferrimagnetic materials are strong magnetic substances, and the so-called magnetic materials generally refer to strong magnetic materials. For magnetic materials, magnetization curves and hysteresis loops are characteristic curves that reflect their basic magnetic properties. Ferromagnetic materials are generally Fe, Co, Ni elements and their alloys, rare earth elements and their alloys, and some Mn compounds. Magnetic materials are generally divided into soft magnetic materials and hard magnetic materials based on the ease or difficulty of magnetization.

[0003] The original magnetic material will produce non-magnetic and magnetic waste during the grinding process. Through searching, CN210700619U was found, which discloses a recovery device for magnetic material grinding waste, including a shell assembly, a buffer assembly and an adsorption assembly. The shell assembly includes a box body, a cover body, a feed pipe, a first support plate, a second support plate, a box door, a support column and a material receiving box; an electric push rod is set to push the screen to move back and forth on the slide rail to generate shaking, so that the waste falling on the screen can slow down the falling speed and fall evenly from the mesh to the electromagnet for adsorption; by setting the first electromagnet and the second electromagnet to rotate under the drive of the rotating motor, not only the adsorption area is increased, but also the accumulation of waste on the first electromagnet and the second electromagnet themselves can be avoided during rotation, so that the non-magnetic waste falls into the collection box, without manual operation, improving the collection efficiency, and avoiding the harm of waste to the staff.

[0004] However, when recycling magnetic material grinding waste, it is necessary to recycle non-magnetic waste first before recycling magnetic material grinding waste. The operation is cumbersome and time-consuming, so it needs to be improved. Utility Model Content

The two notched conductive rings 16 are symmetrically fixedly connected to the inner wall of the recycling box 1.

By setting the screening mechanism 4 and the magnetic suction sorting mechanism 10, the non-magnetic waste will first pass through the screening mechanism 4, and the triangular plate 5 and the limit baffle 7 will be used for sorting. The non-magnetic waste will fall into the second recycling box 9, and the magnetic material grinding waste will be attracted by the bar electromagnet 17 inside the first magnetic roller 12 and the second magnetic roller 13. As the first magnetic roller 12 and the second magnetic roller 13 continue to rotate, when the conductive wheel 22 is not in contact with the notched conductive ring 16, the adjacent bar electromagnet 17 will be powered off, causing the magnetic material grinding waste to fall into the first recycling box 8.

The elastic force of the first spring 20 is used to support the conductive wheel 22 through the wheel frame 21, so that the conductive wheel 22 can be close to the notched conductive ring 16. At this time, the current passes through the notched conductive ring 16, the conductive wheel 22 and the bar electromagnet 17 to connect, thereby turning on the bar electromagnet 17, and the magnetic material grinding waste will be attracted by the bar electromagnet 17 inside the first magnetic roller 12 and the second magnetic roller 13.
