Description

Technical Field

[0001] This invention relates to the field of metal recycling technology, specifically to a low-melting-point metal recycling device. Background Technology

[0002] Low melting point metals refer to metals and their alloys with a melting point below 300 degrees Celsius. They are usually composed of low melting point metal elements such as Bi, Sn, Pb, and In. These alloys are often used to manufacture plastic molds, deep drawing dies, and forming dies.

[0003] During the processing of some housing components, due to their thin walls, they are prone to deformation. It is usually necessary to pour low-melting-point metal materials into the inside of the housing to temporarily enhance the structural rigidity and suppress processing deformation. After processing is completed, the support material needs to be recycled. However, during the processing, the housing may be covered with oil or mixed with mechanical impurities such as high-melting-point copper and iron filings. If it is directly melted and used, it is easy to cause secondary pollution and performance degradation. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This low-melting-point metal recycling equipment, through its isolation heat conduction turbulence mechanism, heating melting mechanism, centrifugal slag filtering mechanism, and heat preservation heating mechanism, can use the centrifugal rotation of the heating melting mechanism and the centrifugal slag filtering mechanism to separate solid and oily impurities from the molten low-melting-point metal liquid during use, thereby ensuring the purity of the low-melting-point metal material when it is melted and used.

[0017] This low-melting-point metal recycling equipment, through its insulated heat-conducting shell, heat exchange plates, driven conical tooth ring, inner insert, inner support ring, sliding seal ring, lower edge shell, drain ring, inlet shell, and inlet hole, can achieve heat conduction and isolation during use. The rotating heat exchange plates increase the heat exchange area, and the flow of the heat transfer fluid is circulated through the drainage ring and inlet shell in conjunction with the rotation of the heat exchange plates, thereby avoiding uneven heat conduction.

[0018] This low-melting-point metal recovery equipment, through its heating vessel, anti-condensation heating ring, positioning outer ring, anti-splash ring, actuating groove, heat-conducting sealing ring, grip, locking hole, connecting seat, pull tab, centrifugal counterweight, connecting pull ring, pull head, and limiting ball, enables the independent separation of materials after heating through the heating vessel and the limiting of the heating vessel through the positioning outer ring. At the same time, the pull tab unit composed of the connecting seat, pull tab, centrifugal counterweight, connecting pull ring, pull head, and limiting ball enables quick disassembly of the centrifugal filter mechanism. During rotation, the centrifugal counterweight ensures that the pull tab forms a downward pulling force to maintain rotation. Furthermore, the anti-condensation heating ring prevents the metal solution from prematurely cooling and solidifying when removing the centrifugal filter mechanism to retrieve oily impurities.

[0019] This low-melting-point metal recovery equipment, through its anti-splash rings, screens, filter screen holders, fixed forks, and filter liners, can isolate solid particulate impurities during rotation, ensuring that molten metal can pass through and be filtered smoothly.

[0020] This low-melting-point metal recycling equipment, through its centrifugal motor, drive bevel gear, heat-insulating heating shell, heating block, temperature controller, sealing ring, inner connecting ring, mechanical shell, motor shell, mounting base, first electromagnetic lock, cover ring, second electromagnetic lock, light-transmitting cover, and air inlet, can drive the insulating heat-conducting shell to form a centrifugal rotation motion. This ensures that relatively light oily impurities move upwards towards the axis of rotation, thereby ensuring that more oily impurities can be removed when the filter liner is taken out.

The light-transmitting cover 414 is fixedly connected to the surface of the cover ring 412. The air inlet 415 is fixedly installed on the surface of the light-transmitting cover 414. The mechanism is powered by a centrifugal motor 401, a drive bevel gear 402, and the heat preservation and heating shell 403. The heating element 404, temperature controller 405, sealing ring 406, inner connecting ring 407, mechanical housing 408, motor housing 409, mounting base 410, first electromagnetic lock 411, cover ring 412, second electromagnetic lock 413, light-transmitting cover 414, and air inlet 415 can drive the insulating heat-conducting shell 101 to form a centrifugal rotation motion through the centrifugal motor 401, ensuring that relatively light oily impurities move upwards towards the axis of rotation, thereby ensuring that more oily impurities can be removed when the filter liner 305 is taken out.

[0042] Working principle:

[0043] In use, first connect the light-transmitting cover 414 to the external air pipe, then open the light-transmitting cover 414, align the actuating groove 205 with the inner insert 104, then slide the heating vessel 201 into the heat-conducting insulating shell 101, then move the positioning outer ring 203 so that the locking hole 208 corresponds to the first electromagnetic lock 411, then activate the first electromagnetic lock 411 so that the locking tongue of the first electromagnetic lock 411 inserts into the locking hole 208 to lock the positioning outer ring 203, then place the centrifugal filter mechanism into the interior of the heating vessel 201 so that the inner wall of the anti-splash ring 204 fits against the surface of the filter liner 305. Replace the new screen 302, then rotate the pull-button unit so that the pull-button piece 210 pushes the pull head 213 through the pull ring 212, and the limiting ball 214 is inserted into the fixed fork hook 304. Then pull back the pull-button piece 210 so that the limiting ball 214 pulls the fixed fork hook 304 tight and fixes it on the surface of the splash ring 204. Then place the low melting point metal material inside the filter liner 305, close the sealing light-transmitting cover 414, lock the second electromagnetic lock 413, then extract the air inside the device through the air inlet 415 and then inject inert protective gas into the device through the air inlet 415.

[0044] Then, the heating block 404 and the anti-condensation heating ring 202 are energized and heated. After the anti-condensation heating ring 202 is energized, it heats the anti-splash ring 301, the anti-condensation heating ring 202, and the heating vessel 201 through the thermally conductive sealing ring 206. The heating block 404 heats the heat-conducting shell 101 evenly through the heat-conducting liquid inside the heat-insulating heating shell 403. Then, the heat-conducting shell 101 transfers heat to the heating vessel 201, causing the temperature inside the heating vessel 201 to rise and the material to gradually melt. At the same time, the temperature inside the heating vessel 201 is maintained by the feedback of the temperature controller 405. Then, the centrifugal motor 401 is started. The centrifugal motor 401 drives the active bevel gear 402 to drive the driven bevel gear ring 103, causing the isolation heat-conducting shell 101 to rotate. When the isolation heat-conducting shell 101 rotates, it drives the heat exchange plate 102 to rotate. When the heat exchange plate 102 rotates, it generates a centrifugal force that continuously pushes the heat-conducting liquid in the middle to the surrounding area, so that the heat-conducting liquid continuously flows upward from the inlet hole 110, then flows upward along the inlet shell 109 and is discharged from the outlet ring 108, and then flows downward along the interior of the heat-insulating heating shell 403 back to the electric heating block 404, thereby ensuring that the heat-conducting liquid continuously circulates and continuously conducts heat to the isolation heat-conducting shell 101.

[0045] Meanwhile, the rotating heat-conducting shell 101 drives the heating vessel 201 and the molten metal liquid inside it as well as the centrifugal filter residue mechanism to rotate. When rotating, the high melting point metal and solid impurities inside the molten metal liquid will be intercepted and stuck on the inner surface of the filter liner 305, while the molten metal can easily pass through the filter liner 305, the screen 302 and the filter residue screen holder 303. Due to the centrifugal effect, light oily impurities will concentrate in the middle of the filter liner 305 near the axis and will also float on its surface.

[0046] After centrifugation, the inert protective gas is withdrawn and air is injected to maintain constant pressure before the light-transmitting cover 414 is opened. Then, the centrifugal filter mechanism is removed. At this time, the molten inert metal liquid will flow through the filter liner 305, the screen 302 and the filter residue holder 303 into the heating vessel 201. The oily impurities, high-melting-point metals and solid impurities are intercepted inside the filter liner 305 and float on the surface. Then, the centrifugal filter mechanism is removed to retrieve the oily impurities, thereby recovering relatively pure low-melting-point metal materials.
