Description

Technical Field

[0001] The invention relates to the technical field of waste copper casting, and in particular to waste copper recovery, smelting and casting equipment and a working method thereof. Background Art

[0002] Copper alloys have excellent mechanical properties and very low resistivity, the most important of which are bronze and brass. In addition, copper is also a durable metal that can be recycled many times without damaging its mechanical properties. Scrap copper recycling is generally done by burning or heating it to melt it, and then replacing it through a series of chemical methods to form copper powder, which requires the use of smelting and casting equipment.

[0003] When using existing scrap copper recovery, smelting and casting equipment, it is usually melted directly. The large volume of some scrap copper will affect its smelting efficiency and reduce the effect of the device. In addition, after smelting, impurities will float on the surface of the scrap copper.

[0016] The present invention also provides a method for recycling, smelting and casting waste copper, which uses the above-mentioned device to take samples, and comprises the following steps:

[0017] S1: When in use, the scrap copper can be added to the inner cavity of the feed box, and before adding, the operation of the driving motor can drive the crushing roller on one side to rotate, and the transmission of the movable gear can drive the crushing rollers on both sides to rotate synchronously and oppositely, so that the added scrap copper can be crushed, and the scrap copper on the side after crushing will enter the inner cavity of the screening drum through the discharge pipe, and the movable gear will also drive the transmission gear to rotate when rotating, and the transmission gear will drive the gear ring to rotate when rotating, so as to drive the screening drum to rotate and screen the crushed scrap copper, and the scrap copper screened by the screening drum will fall into the inner cavity of the smelting box, and the scrap copper can be smelted by the operation of the heating element, and the driving motor will drive the worm to rotate through the transmission of the belt C when running, and the stirring element can be driven to rotate in the inner cavity of the smelting box through the transmission of the worm wheel when the worm rotates, so as to turn the scrap copper raw material over and accelerate the smelting rate;

[0018] S2: When the worm rotates, the transmission of belt B will drive the magnetic field cutting coil to rotate. When the magnetic field cutting coil rotates, it will cut the magnetic induction line between the S-pole magnet and the N-pole magnet. In addition, a closed loop will be formed between the magnetic field cutting coil and the electromagnet. The closed loop formed between the magnetic field cutting coil and the electromagnet will energize the electromagnet, thereby generating an attraction to the magnet block. The magnetic attraction between the electromagnet and the magnet block is greater than the pulling force of the reset spring. At this time, the magnet block will move to the side close to the electromagnet. When the magnet block is on one side, the reset spring will be stretched, and the rack plate will also be driven to move. When the rack plate moves, it will drive the rotating gear to rotate. When the rotating gear rotates, it will rotate in contact with the ratchet and squeeze the telescopic spring back and forth. In addition, when the magnet block moves to the maximum attraction, it will stop moving;

[0019] S3: After the scrap copper is smelted, impurities will float on the surface. At this time, the driving motor can be stopped. When the driving motor stops running, the electromagnet will be powered off, which will drive the rack plate to recover under the action of the rebound force of the reset spring, thereby driving the rack plate to rotate. At this time, the inner wall of the ratchet groove is engaged with the pawl, thereby driving the turntable to rotate. When the turntable rotates, it drives the transmission shaft to rotate. When the transmission shaft rotates, it drives the active bevel gear to rotate through the transmission of belt A. When the active bevel gear rotates, it drives the reciprocating screw to rotate through the driven bevel gear. When the reciprocating screw rotates, it drives the screw nut The U-shaped rod drives the L-shaped sliding sleeve to move. When the L-shaped sliding sleeve moves, it drives the cleaning frame to move through the movable plate. When the movable plate moves, it also drives the sliding shaft to slide in the inner cavity of the special-shaped groove. As the cleaning frame moves, it will slowly move downward under the action of the special-shaped groove. At this time, the cleaning frame will move from the inner cavity of the rectangular mouth to the inner cavity of the smelting box. At the same time, when the cleaning frame is away from the rectangular mouth, it will drive the movable plate to slide downward in the inner cavity of the L-shaped sliding sleeve for a certain distance, thereby entering the inner cavity of the molten metal liquid. As the cleaning frame moves, impurities can be scooped into its inner cavity.

[0020] S4: As the screw nut continues to move, the cleaning frame will be driven to slowly move upwards under the action of the special-shaped groove and enter the inner cavity of the rectangular opening on the other side, making it convenient for the staff to clean the impurities therein;

[0021] S5: Finally, by setting the discharge pipe, the valve can be opened to discharge the smelted metal liquid, which is convenient for subsequent manufacturing.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Through the cooperation among the fixed semicircular ring, screening cylinder, gear ring, transmission gear, semicircular block, shaking plate, movable shaft, scroll spring and fixed rod, the crushed scrap copper raw materials can be filtered. In addition, the rotating screening cylinder will drive the semicircular block to contact the shaking plate back and forth continuously, which will vibrate the screening cylinder when it rotates and improve the screening effect.

[0024] 2. Through the cooperation among the cleaning components, cleaning frame, movable plate, L-shaped sliding sleeve, U-shaped rod, screw screw, reciprocating screw, driven bevel gear, active bevel gear and belt A, the impurities floating on the surface of the molten metal can be cleaned, which is convenient for the staff to handle it and improve the quality of the molten metal.

[0025] 3. Through the mutual cooperation among the protective frame, belt B, magnetic field cutting coil, S-pole magnet, N-pole magnet, electromagnet, magnet block, straight plate, moving rod, reset spring, rack plate, rotating gear, hollow ring, turntable, transmission shaft, pawl and telescopic spring, the operation of the cleaning assembly can be powered and the operation is convenient.

[0051] The present invention also provides a method for recycling, smelting and casting waste copper, which uses the above-mentioned device to take samples, and comprises the following steps:

[0052] S1: When in use, the scrap copper can be added to the inner cavity of the feed box 3, and before adding, the operation of the driving motor 4 can drive the crushing roller 5 on one side to rotate, and the transmission of the movable gear 6 can drive the crushing rollers 5 on both sides to rotate synchronously and oppositely, so that the added scrap copper can be crushed, and the scrap copper on the side after the crushing will enter the inner cavity of the screening drum 72 through the discharge pipe, and the movable gear 6 will also drive the transmission gear 74 to rotate when it rotates, and the transmission gear 74 will drive the gear ring 73 to rotate when it rotates, so that the screening drum 72 can be driven to rotate to screen the crushed scrap copper, and the scrap copper screened by the screening drum 72 will fall into the inner cavity of the smelting box 1, and the operation of the heating element 12 can be used to smelt the scrap copper, and the driving motor 4 will drive the worm 30 to rotate through the transmission of the belt C40 when it is running, and the worm 30 can be driven to rotate through the transmission of the worm wheel 20 when the worm 30 rotates, so that the stirring element 10 can be driven to rotate in the inner cavity of the smelting box 1, so as to turn the scrap copper raw material over and accelerate the smelting rate;

[0053] S2: When the worm 30 rotates, the transmission of the belt B92 drives the magnetic field cutting coil 93 to rotate. When the magnetic field cutting coil 93 rotates, it cuts the magnetic induction line between the S-pole magnet 94 and the N-pole magnet 95. In addition, a closed loop is formed between the magnetic field cutting coil 93 and the electromagnet 96. The closed loop formed between the magnetic field cutting coil 93 and the electromagnet 96 will energize the electromagnet 96, thereby generating an attraction force on the magnet block 97. The magnetic attraction force between the electromagnet 96 and the magnet block 97 is greater than the pulling force of the reset spring 973. At this time, the magnet block 97 will be driven to move toward the side close to the electromagnet 96. When the magnet block 97 moves to one side, the reset spring 973 will be stretched, and the rack plate 98 will also be driven to move. When the rack plate 98 moves, it will drive the rotating gear 99 to rotate. When the rotating gear 99 rotates, it will rotate in contact with the ratchet 994 and squeeze the telescopic spring 995 back and forth. In addition, when the magnet block 97 moves to the maximum attraction, it will stop moving;

[0054] S3: After the scrap copper is smelted, impurities will float on the surface. At this time, the driving motor 4 can be stopped. When the driving motor 4 stops running, the electromagnet 96 will be powered off, thereby driving the rack plate 98 to recover under the action of the rebound force of the reset spring 973, thereby driving the rack plate 98 to rotate. At this time, the inner wall of the ratchet groove is engaged with the pawl 994, thereby driving the turntable 992 to rotate. When the turntable 992 rotates, it drives the transmission shaft 993 to rotate. When the transmission shaft 993 rotates, it drives the active bevel gear 88 to rotate through the transmission of the belt A89.
