[0002] The upstream sources of aluminum products are divided into electrolytic aluminum and recycled aluminum. In the past, electrolytic aluminum was the main source of aluminum alloy products, and more than 80% of electrolytic aluminum used thermal power. Due to the high energy consumption and high carbon emissions in the industry, the increase in electrolytic aluminum production capacity needs to be strictly managed and controlled, which limits the overall increase in the industry.

[0003] The production of recycled aluminum is fundamentally different from that of primary aluminum. Its main raw material is scrap aluminum, which can be continuously recycled. It has the characteristics of saving resources, reducing external dependence on aluminum ore resources, environmental protection, and economic advantages. Compared with primary aluminum production, it greatly saves land, water and electricity resources, and is an important part of the circular economy construction of the non-ferrous metal industry. However, it is easy for trace elements to exceed the standard in fully recycled scrap aluminum, which poses a huge challenge to the quality and performance of cast and rolled products. Summary of the invention

DETAILED DESCRIPTION

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0041] In an embodiment of the present invention, a process for producing a cast plate from fully recycled aluminum liquid comprises the following steps:

[0042] Step 1: Screen the waste aluminum wires, use the aluminum wire peripheral processing equipment to clean the outer wall coating of the waste aluminum wires, and then remove the waste aluminum impurities on the surface of the cleaned aluminum wires;

[0043] Step 2: Use a charging cart to load the treated aluminum scrap into an environmentally friendly double-chamber furnace for melting to obtain clean recycled aluminum liquid;

[0044] Step 3, preparing metal additives such as iron, silicon, copper, manganese, titanium, etc. that meet the requirements;

[0045] Step 4: Use a large-capacity melting furnace to adjust the cold material ratio and the alloy composition that meets the performance requirements to improve the performance of the cast aluminum plate;

[0046] Step 5: Smelting treatment: the regenerated aluminum liquid is refined and deslagging using an inert gas and a refining agent, and after the initial deslagging, it is poured into a large-tonnage holding furnace for rest;

[0047] Step 6, further degassing and deslagging the regenerated aluminum liquid through online degassing and filtering equipment;

[0048] Step 7: The recycled aluminum liquid is transferred through the chute, enters the casting nozzle made of ceramic fiber refractory material through the front box, and then passes through the inclined casting and rolling machine to be cast and rolled into recycled aluminum liquid cast and rolled plates;

[0049] Step eight, performing low-power analysis on the recycled aluminum water-cast rolled plate, and screening out the recycled aluminum water-cast rolled plate whose grain size meets the requirements.

[0050] In summary, the process design of this product can achieve the use of all recycled materials, and the cast-rolled plates have good performance after cold rolling and foil rolling, gradually replacing the traditional "two high" products such as electrolytic aluminum and aluminum ingots, and reducing production costs.

[0051] See also Figure 1-7 The aluminum wire peripheral processing equipment includes a base 1 and two vertical plates 2 fixedly mounted on the base 1, and also includes:

[0052] A round tube 3, one of which is fixedly mounted on each of the two vertical plates 2, and the two round tubes 3 are used to allow the untreated and treated aluminum wires to pass through, respectively, and the treated aluminum wires are wound and collected by a wire roller 9 movably arranged on the base 1;

[0053] The transverse plate 4 is movably mounted on the base 1 and connected to the reciprocating drive mechanism mounted on the base 1. The line roller 9 is rotatably mounted on the transverse plate 4, and the rotating shaft of the line roller 9 is connected to the reciprocating drive mechanism through a transmission mechanism, and the transmission mechanism is connected to the Maltese cross movement mechanism mounted on the base 1;

[0054] Two cutters 6 are fixed on the vertical plate 2 away from the wire roller 9. When the Maltese cross movement mechanism is used to drive the wire roller 9 to perform winding action on the aluminum wire, the two cutters 6 can cut the outer skin of the aluminum wire between the two.

[0055] The reciprocating lifting mechanism is installed on the base 1 and connected to the Maltese cross movement mechanism. The reciprocating lifting mechanism is connected to an elastic impact mechanism. When the Maltese cross movement mechanism drives the reciprocating lifting mechanism to move, the reciprocating lifting mechanism drives the elastic impact mechanism to reciprocate and lift, so that the elastic impact mechanism performs a stripping action on the outer skin of the cut aluminum wire.

[0056] In actual use, the staff will pass one end of the aluminum wire to be pretreated through the two round tubes 3 in sequence, and use the two cutters 6 to cut the outer skin of the aluminum wire during this process, and then connect the aluminum wire to the wire roller 9;

[0057] Subsequently, the Maltese cross movement mechanism works, driving the transmission mechanism and the reciprocating lifting mechanism to move alternately. When the transmission mechanism moves, it drives the wire roller 9 to rotate, and the wire roller 9 winds up the aluminum wire, so that the aluminum wire is cut when passing through the two cutters 6. At the same time, the transmission mechanism drives the reciprocating drive mechanism to move, and the reciprocating drive mechanism drives the transverse plate 4 and the wire roller 9 to reciprocate linearly, ensuring that the aluminum wire can be evenly wound up on the wire roller 9.

[0058] When the reciprocating lifting mechanism moves, it will drive the elastic impact mechanism to reciprocate and lift, and perform a stripping action on the outer skin of the cut aluminum wire. This cycle is repeated to achieve the automatic processing function of the outer periphery of the aluminum wire, avoiding the problem of low work efficiency caused by manual operation.

[0059] Please refer again Figure 1 The Maltese cross movement mechanism includes a first driven wheel 11 and a second driven wheel 12 rotatably mounted on the base 1, and a driving motor 13 mounted on the base 1, and a driving wheel 10 is fixedly mounted on the output end of the driving motor 13; the driving wheel 10 cooperates with the first driven wheel 11 and the second driven wheel 12, the rotating shaft of the first driven wheel 11 is connected to the transmission mechanism, and the rotating shaft of the second driven wheel 12 is connected to the reciprocating lifting mechanism.

[0060] Please refer again Figure 6 The transmission mechanism includes a transmission tube 21 rotatably mounted on the base 1 and connected to the rotating shaft of the first driven wheel 11 through a first transmission belt 14, the transmission tube 21 is slidably fitted with the rotating shaft of the line roller 9, and is connected to the reciprocating drive mechanism;

[0061] A plurality of strip-shaped grooves are equidistantly arranged on the inner wall of the transmission tube 21 along the circumference, and strip-shaped protrusions matching the strip-shaped grooves are equidistantly arranged on the outer wall of the rotating shaft of the line roller 9 along the circumference.

[0062] When the driving motor 13 is working and drives the active wheel 10 to drive the first driven wheel 11 to rotate, the rotating shaft of the first driven wheel 11 drives the transmission tube 21 to rotate through the first transmission belt 14, and then the transmission tube 21 drives the wire roller 9 to rotate through the strip groove and the strip protrusion, so that the wire roller 9 winds up the aluminum wire, making it easier for the two cutters 6 to cut the outer skin of the aluminum wire that passes through.

[0063] Two cross bars 5 are fixedly mounted on the base 1, and the transverse plate 4 is slidably arranged on the two cross bars 5, and two protrusions 22 are arranged at the bottom of the transverse plate 4, and a gap is reserved between the two protrusions 22;

[0064] The reciprocating drive mechanism includes two driving wheels 16 rotatably mounted on the base 1, a connecting member 17 rollingly connecting the two driving wheels 16, and a first column 18 arranged on the connecting member 17, the first column 18 extends into the gap and is slidably connected to the two protrusions 22, and the rotating shaft of one of the driving wheels 16 is connected to the transmission pipe 21 through a third transmission belt 19 and a bevel gear set 20.

[0065] In detail, the bevel gear set 20 includes a first bevel gear fixedly mounted on the transmission tube 21 and a second bevel gear rotatably mounted on the base 1 and meshing with the first bevel gear. The third transmission belt 19 is used to connect the rotating shafts of the second bevel gear and the driving wheel 16.

[0066] When the transmission tube 21 rotates, the driving wheel 16 will be driven to rotate through the bevel gear set 20 and the third transmission belt 19, and then the first column 18 will follow the movement of the connecting piece 17, and slide with the two protrusions 22 at its movement end points, so that the transverse plate 4 slides back and forth on the two cross bars 5, ensuring that the aluminum wire can be automatically and evenly wound onto the wire roller 9.

[0067] Please refer again Figure 5 and Figure 7 A vertical plate 23 is fixedly mounted on the base 1, and a telescopic plate 24 is slidably fitted inside the vertical plate 23. The two are connected through the reciprocating lifting mechanism. The cross-section of the telescopic plate 24 is set in an "L" shape, and the elastic impact mechanism is installed at the top of the telescopic plate 24.

[0068] The elastic impact mechanism includes two guide rods 26 fixedly mounted on the telescopic plate 24 through a protruding block 25 and two sliders 27 slidably connected to the two guide rods 26, and two cylindrical springs 28 are respectively sleeved on the outer circumference of the two guide rods 26, one end of the cylindrical spring 28 is connected to the protruding block 25, and the other end is connected to the slider 27, and a round roller 29 is rotatably installed at the bottom of each of the two sliders 27.

[0069] When the second driven wheel 12 drives the reciprocating lifting mechanism to move, the reciprocating lifting mechanism will drive the telescopic plate 24 to slide up and down in the vertical plate 23. When the vertical plate 23 slides downward, after the round rollers 29 contact the outer skin of the aluminum wire, the two round rollers 29 will give way and move closer to each other, and the cylindrical spring 28 will be compressed.

[0070] Preferably, an anti-skid rubber sleeve is provided on the outer circumference of the round roller 29 to increase the friction between the outer wall of the round roller 29 and the outer skin of the aluminum wire, thereby ensuring that the round roller 29 can peel off the outer skin of the aluminum wire smoothly.

[0071] The reciprocating lifting mechanism includes a transmission shaft 34 rotatably mounted on the base 1 and connected to the rotation axis of the second driven wheel 12 through a second transmission belt 15, a cam 32 fixed to one end of the transmission shaft 34, and a second column 33 fixed to the cam 32;

[0072] A connecting column 30 is fixed on both sides of the telescopic plate 24, and a driven plate 31 is fixedly connected between the two connecting columns 30. A through groove for the movement of the connecting column 30 is opened on the side of the vertical plate 23, and a sliding groove is opened on the driven plate 31. The second column 33 extends into the sliding groove and is slidably connected with the driven plate 31.

[0073] When the second driven wheel 12 rotates, its rotating shaft will drive the transmission shaft 34 and the cam 32 to rotate one circle through the second transmission belt 15, and then the cam 32 will drive the second cylinder 33 to perform a circular motion, and the second cylinder 33 will slide with the driven plate 31 during the circular motion, so that the driven plate 31 drives the telescopic plate 24 to first descend and then rise and reset in the vertical plate 23 through the connecting column 30, and the two round rollers 29 complete a peeling action on the outer skin of the aluminum wire.

[0074] Please refer again Figure 4 It should be supplemented that a cylinder 8 is installed on one side of the vertical plate 2 farther from the wire roller 9, and a clamping member 7 is respectively fixed to the top of the vertical plate 2 and the movable end of the cylinder 8. The clamping member 7 is arranged in an arc shape, and is used to clamp the aluminum wire whose outer skin has not been cut when the second driven wheel 12 rotates (that is, when the two round rollers 29 perform a stripping action on the outer skin of the aluminum wire), so that the end of the aluminum wire away from the wire roller 9 is locked, and the aluminum wire between the two vertical plates 2 remains in a straight state, preventing the aluminum wire from bending due to force when the round roller 29 performs the stripping action, thereby ensuring the smoothness of the two round rollers 29 performing the stripping action.

[0075] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
