Description

Technical Field

[0001] This utility model relates to the field of waste linear motor magnetic block recycling technology, specifically a waste linear motor magnetic block separator. Background Technology

[0002] In waste linear motors, rare earth permanent magnet materials such as neodymium iron boron account for more than 60% of the cost, making them extremely valuable for recycling. These high-performance rare earth permanent magnet materials, after recycling, can be widely used in new energy vehicle drive motors, wind power generation equipment, and other fields, helping to reduce dependence on primary rare earth mineral resources, improve resource utilization efficiency, and yield significant economic and environmental benefits.

[0003] However, several key technical challenges remain in the existing recycling process, severely hindering the efficient recycling and high-value reuse of rare earth permanent magnet materials. First, the magnetic blocks in linear motors are typically recycled together with molten metal cuttings. While larger magnetic blocks can be initially recovered manually or mechanically, a large number of fine magnetic particles are difficult to separate and collect effectively due to their inclusion in the cutting fluid, resulting in significant resource waste. Second, some magnetic blocks are bonded to the inside of the plastic shell using epoxy resin or polyurethane adhesive. Because these adhesives have extremely strong bonding forces after curing, peeling the magnetic blocks from the substrate is difficult and inefficient. Traditional physical dismantling methods struggle to achieve rapid and thorough separation, further reducing recycling efficiency and automation levels.

[0004] Therefore, it is particularly important to design a waste linear motor magnetic block separator to overcome the above-mentioned technical defects and improve its overall practicality. Utility Model Content

[0023] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0024] A waste linear motor magnetic block separator includes a fixed base plate 1. Fixed crossbars 2 extending along the length direction are provided on both the left and right sides of the fixed base plate 1. A forward and reverse motor 201 is installed at the front end of the fixed crossbar 2. The output end of the forward and reverse motor 201 passes through the interior of the fixed crossbar 2 and is connected to a rotating screw 202. A screw sleeve 203 is threaded on the outer side of the rotating screw 202. A separation bracket 3 is provided between the tops of the two sets of screw sleeves 203. An electric cylinder 301 is installed on the top of the separation bracket 3. The output end of the electric cylinder 301 passes through the bottom of the separation bracket 3 and is connected to a solenoid roller 302. A separation box 4 is installed on the front side of the top of the fixed base plate 1.

[0025] Both ends of the rotating screw 202 are rotatably connected to the inside of the fixed crossbar 2 through bearing seats. The top of the fixed crossbar 2 is provided with a sliding groove for the screw sleeve 203 to move. The electromagnetic roller 302 is made of neodymium iron boron permanent magnet material.

[0026] In this embodiment, please refer to Figure 3 Heating rods 401 are evenly installed on the bottom of the inner side of the separation box 4. A dry and wet separation box 5 is set on the top of the fixed base plate 1 and behind the separation box 4. Squeezing rollers 501 are symmetrically rotated and connected to the upper part of the inner side of the dry and wet separation box 5. The right ends of the two sets of squeezing rollers 501 pass through the dry and wet separation box 5 and are connected to meshing gears 502. A drive motor 503 is installed on the right side of the dry and wet separation box 5. The drive motor 503 is connected to one of the gears 502. A filter screen plate 504 is slidably connected inside the dry and wet separation box 5 and below the squeezing rollers 501. Oil drain pipes 6 are connected to the bottom of the right side of the separation box 4 and the dry and wet separation box 5. A control valve 601 is installed on the oil drain pipe 6 for recovering cutting fluid.

[0027] The outer side of the fixed base plate 1 is equipped with a control panel, which is connected to the forward and reverse motor 201, electric cylinder 301, electromagnetic roller 302, heating rod 401, drive motor 503, and control valve 601 by wires, and the connection is electrical. The extrusion roller 501 is made of nitrile or polyurethane material, and the filter screen 504 is slidably installed inside the dry and wet separation box 5 and opens backward.

[0028] The working process of this utility model is as follows: In use, the cutting liquid mixed with magnetic block particles is poured into the separation chamber 4. The heating rod 401 is started to heat the liquid. After heating, the viscosity of the oil film on the surface of the oil-containing magnetic block particles is reduced by 85%, making it easier for the magnetic block particles to separate from the substrate interface. Then, the forward and reverse motor 201 is started to drive the rotating screw 202 to rotate, thereby moving the threaded drive screw sleeve 203. This causes the separation bracket 3 to move to the position of the separation chamber 4 first. The electric cylinder 301 is started, which drives the energized electromagnetic roller 302 to move down and extend into the separation chamber 4. The magnetic particles are adsorbed, then the electric cylinder 301 retracts, and the separation bracket 3 continues to move above the dry and wet separation box 5. The electromagnetic roller 302 is de-energized, and the magnetic particles fall onto the squeezing roller 501. Under the action of the drive motor 503, the two sets of gears 502 drive the squeezing roller 501 to rotate. The squeezing roller 501 applies pressure (0.2-0.5MPa) to the adsorbed impurity layer, squeezing out the entrained liquid. The magnetic particles fall onto the filter screen 504 to achieve dry and wet separation. Finally, the filter screen 504 can be slid out for collection.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
