[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figure 1-4 The present invention provides an efficient aluminum metal recovery device, comprising a separation furnace body, an exhaust mechanism and a cold ash feeding mechanism; the exhaust mechanism is fixedly mounted on the top of the separation furnace body; the cold ash feeding mechanism is fixedly mounted on the side wall of the separation furnace body;

[0031] The separation furnace body includes a furnace shell 5, a stirring assembly and a heating assembly; a feed port 9 is opened on the peripheral wall of the furnace shell 5; the stirring assembly is fixedly installed on the top of the inner cavity of the furnace shell 5, and the heating assembly is fixedly installed on the peripheral wall of the furnace shell 5; the stirring assembly includes a partition 7, which is horizontally fixedly installed on the peripheral wall of the inner cavity of the furnace shell 5 and is limited above the feed port 9; a stirring motor 6 is fixedly installed on the top surface of the partition 7; the output end of the stirring motor 6 faces downward and is fixedly connected to a stirring shaft 8; the stirring shaft 8 is vertically arranged and a number of stirring blades 14 are fixedly installed on the bottom.

[0032] The upper part of the furnace shell 5 is a cubic structure, which is convenient for the opening of the feed port 9 and the installation of the cold ash feeding mechanism; the lower part of the furnace shell 5 is a hemispherical structure, which can adapt to the operation of the stirring mechanism, and fully stir the aluminum slag in the furnace shell 5, and then separate and stratify it.

[0033] The heating assembly includes a heating wire 13 ; the heating wire 13 is wound around the outer wall of the furnace shell 5 and corresponds to the position of the stirring blade 14 ; an insulating sleeve 12 is fixedly installed around the heating wire 13 .

[0034] The heating wire 13 is a tungsten wire, and the insulating sleeve 12 is an insulating high-temperature resistant material, which can heat the aluminum slag in the furnace shell 5 until the aluminum is melted.

[0035] In another embodiment of the present application, the heating mechanism is eddy current heating, and the heating wire 13 is a copper coil. When power is turned on, the metal in the furnace shell can be heated to melt. The staff only needs to control the temperature so that the aluminum just melts; the stirring shaft 8 and the stirring blade 14 are made of high temperature resistant materials.

[0036] The cold ash feeding mechanism includes a feeding tube 26; an ash inlet 30 and an ash outlet 32 are provided on the peripheral wall of the feeding tube 26; the ash inlet 30 faces upward and the ash outlet 32 faces downward; one end of the feeding tube 26 passes through the side wall of the furnace shell 5 and extends into the inner cavity of the furnace shell 5; the ash inlet 30 is located on the outside of the furnace shell 5, and the ash outlet 32 is located in the inner cavity of the furnace shell 5; the feeding tube 26 is fixedly connected to the furnace shell 5; a rotating shaft 28 is coaxially provided in the feeding tube 26; the rotating shaft 28 and both ends of the feeding tube 26 are rotatably connected through bearings; a spiral plate 29 is welded to the peripheral wall of the rotating shaft 28 along the length direction; the end of the rotating shaft 28 away from the furnace shell 5 is transmission-connected to the feeding motor 25.

[0037] The provision of the cold ash feeding mechanism can replace manual addition of cold ash, thereby improving work efficiency. The position of the feeding cylinder 26 is limited to below the partition 7 and above the stirring blade 14.

[0038] A number of support rods 31 are fixedly installed horizontally in the ash inlet 30; a top block 36 is fixedly installed on the top surface of the support rod 31; an ash storage bin 27 is detachably installed on the top of the ash inlet 30; the ash storage bin 27 is connected with the inner cavity of the feed cylinder 26 through the ash inlet 30; a number of sliding rods 35 are fixedly installed vertically in the circumferential direction on the bottom surface of the inner cavity of the ash storage bin 27 near the ash inlet 30; a stopper 34 is provided in the inner cavity of the ash storage bin 27 directly above the ash inlet 30; the sliding rod 35 passes through the stopper 34 and is slidably connected to the stopper 34; the top block 36 abuts against the stopper 34.

[0039] The arrangement of the top block 36 and the stopper 34 can make the replacement and addition of the ash storage bin 27 more convenient and safe. The top block 36 can push the stopper 34 to slide on the slide rod 35. When the ash storage bin 27 is installed on the ash inlet 30 of the feed tube 26, the top block 36 will lift the stopper 34, so that the outlet at the bottom of the ash storage bin 27 will be opened, and the inner cavity of the ash storage bin 27 will be connected with the inner cavity of the feed tube 26, so that the cold ash will fall into the feed tube 26 along the stopper 34 and the top block 36. The support rods 31 are arranged in an interlaced manner, and the top block 36 is fixedly mounted on the top surfaces of these support rods 31. The cross-sectional diameter of the top block 36 is smaller than the diameter of the ash inlet 30. The cold ash can flow into the inner cavity of the feed tube 26 along the gaps between the support rods 31, and then be sent into the furnace shell 5.

[0040] The bottom end of the furnace shell 5 is a transparent structure and a sealing cover 20 is detachably installed. A servo motor 24 is fixedly installed on the outer wall of the furnace shell 5 near the sealing cover 20. The output end of the servo motor 24 is fixedly connected to a connecting rod 23. A hydraulic cylinder 22 is fixedly installed on the connecting rod 23. The telescopic rod of the hydraulic cylinder 22 is fixedly connected to the sealing cover 20. The telescopic rod of the hydraulic cylinder 22 is perpendicular to the end face of the sealing cover 20.

[0041] The sealing cover 20 can intercept the aluminum slag before processing and keep it away from the furnace shell 5. When the processing is completed, it can be opened to discharge the remaining aluminum slag. The shape of the sealing cover 20 is also arc-shaped and matches the hemispherical shape of the lower half of the furnace shell 5. When the sealing cover 20 is in a closed state, it cannot be rotated open, so it is necessary to first detach it from the furnace shell 5 through the hydraulic cylinder 22 and then rotate it open.

[0042] An aluminum outlet hole 21 is formed on the sealing cover 20 ; an aluminum outlet pipe 16 is connected to the outside of the aluminum outlet hole 21 ; and a valve 19 is provided on the aluminum outlet pipe 16 .

[0043] The aluminum tapping hole 21 allows the molten aluminum in the furnace shell 5 to flow out. A scraper 15 is fixedly installed at the bottom of the stirring shaft 8; the bottom of the scraper 15 is close to the aluminum tapping hole 21. While rotating with the stirring shaft 8, the scraper 15 can scrape away the aluminum slag around the aluminum tapping hole 21 to prevent the aluminum slag from entering the aluminum tapping hole 21 and hindering the outflow of aluminum.

[0044] In another embodiment of the present application, a metal mesh is installed in the aluminum outlet 21 , which can penetrate the molten aluminum and intercept the remaining aluminum slag in the furnace shell 5 .

[0045] An aluminum outlet hole 21 is formed on the sealing cover 20 ; an aluminum outlet pipe 16 is connected to the outside of the aluminum outlet hole 21 ; and a valve 19 is provided on the aluminum outlet pipe 16 .

[0046] The aluminum outlet pipe 16 can introduce the molten aluminum into the collection pool for aluminum collection, and the valve 19 can control the outflow of the aluminum.

[0047] A material guide plate 10 is fixedly installed at the bottom end of the furnace shell 5 at the feed port 9; the material guide plate 10 extends into the furnace shell 5 from the outside to the inside and is tilted downward; a support plate 11 is fixedly connected between the bottom surface of the material guide plate 10 and the peripheral wall of the furnace shell 5.

[0048] The guide plate 10 can facilitate manual addition of aluminum slag raw materials. First, pour the aluminum slag raw materials on the guide plate 10. Because the guide plate 10 is set at an angle, it will automatically slide into the furnace shell 5. The guide plate 10 is located on the side wall of the outer part of the furnace shell 5. A baffle plate is also provided on the side wall of the guide plate 10. The baffle plate can prevent the aluminum slag raw materials poured on the guide plate 10 from spilling out.

[0049] The exhaust assembly includes a bellows 2; the bellows 2 is fixedly mounted on the top surface of the furnace shell 5; an exhaust fan 3 is fixedly mounted inside the bellows 2; the air outlet of the exhaust fan 3 is connected to a ventilation pipe 1; the ventilation pipe 1 passes through the top surface of the bellows 2 and extends to the outside; a plurality of air suction ports 4 are provided on a side surface of the bellows 2 close to the feed port.

[0050] After the exhaust fan 3 is turned on, the fly ash generated by adding aluminum slag raw materials outside can be sucked away through the air suction port 4 on the wind box 2. At the same time, the fly ash leaked from the furnace shell 5 can also be sucked away to prevent environmental pollution.

[0051] A support 17 is fixedly installed on the inner wall of the furnace shell 5 above the feed port 9 ; an ash shield 18 is hingedly connected to the support 17 ; the ash shield 18 completely blocks the feed port 9 .

[0052] The ash baffle 18 can rotate with one end hinged to the support 17 as the center of the circle. In this way, when the aluminum slag raw material slides from the guide plate 10 through the feed port 9 into the inner cavity of the furnace shell 5, the ash baffle 18 can be pushed to rotate, thereby opening the feed port 9. When the filling is completed, the ash baffle 18 returns to a vertical state due to the action of gravity, so that the ash baffle 18 will block the feed port 9, and the material can only move from the outside to the inside, but not from the inside to the outside. Therefore, the dust residue in the furnace shell 5 will not run out from the feed port 9.

[0053] The top ends of every two adjacent sliding rods 35 are fixedly connected to the limiting rod 33 ; the top surface of the stopper 34 is provided with a cone 37 .

[0054] The limiting rod 33 can prevent the stopper 34 from sliding off the slide rod 35 , and the cone 37 can prevent cold ash from accumulating on the top of the stopper 34 , allowing the cold ash to slide along the side wall of the cone 37 and then enter the feed tube 26 .

[0055] When using the present invention, first use a forklift to pour the aluminum slag raw material onto the guide plate 10. Because the guide plate 10 is inclined, the aluminum slag raw material will follow the guide plate 10 through the feed port 9 and fall into the bottom of the inner cavity of the furnace shell 5; then turn on the stirring motor 6, the stirring motor 6 drives the stirring shaft 8 to rotate, and the stirring shaft 8 drives the stirring blade 14 to rotate, thereby stirring the aluminum slag raw material. At the same time, power is supplied to the heating wire 13 to heat the aluminum slag raw material in the furnace shell 5 to make its temperature reach the melting point of aluminum; at this time, the aluminum in the aluminum slag raw material will slowly melt, and after a certain period of stirring, the substances of different densities in the aluminum slag raw material will separate and separate Layer, wherein after the aluminum is melted, the aluminum liquid will flow to the bottom of the furnace shell 5 along the aluminum slag gap, and flow into the aluminum outlet pipe 16 through the aluminum outlet hole 21, and then the valve 19 is opened, and the aluminum liquid flows out of the aluminum outlet pipe 16 and falls into the collection device; while the stirring shaft 8 is rotating, the scraper 15 at the bottom end of the stirring shaft 8 will rotate continuously above the aluminum outlet hole 21, so as to scrape away the aluminum slag above the aluminum outlet hole 21, ensuring that the aluminum outlet hole 21 is not blocked by the aluminum slag, so that the aluminum liquid can flow out normally; when all the aluminum in the aluminum slag raw material is separated, the valve 19 is closed, the power to the heating wire 13 is stopped, and the feed motor 25 is started; the feed motor 25 drives the rotating shaft 28 The rotating shaft 28 drives the spiral plate 29 to rotate; the cold ash in the ash storage bin 27 is then introduced into the furnace shell 5, and mixed with the remaining aluminum slag after processing for cooling. After the temperature of the remaining aluminum slag drops, the hydraulic cylinder 22 is started, and the telescopic rod in the hydraulic cylinder 22 is contracted, driving the sealing cover 20 to move downward for a distance, and then the servo motor 24 is started. The servo motor 24 rotates to drive the connecting rod 23 to rotate, and the connecting rod 23 rotates to drive the hydraulic cylinder 22 and the sealing cover 20 to rotate together, so that the bottom of the furnace shell 5 is opened, and the remaining aluminum slag in the furnace shell 5 will flow out, and finally it can be collected; when the ash storage bin 2 After the cold ash in 7 is used up, the ash storage bin 27 is removed from the feed tube 26. In the process of moving the ash storage bin 27 upward, the stopper 34 will move downward along the slide rod 35 under the action of gravity until it falls on the bottom surface of the inner cavity of the ash storage bin 27 and seals the outlet of the ash storage bin 27 to prevent the residual cold ash inside from spilling out and polluting the environment; after adding cold ash to the ash storage bin 27, the ash storage bin 27 is placed from top to bottom on the ash inlet 30 of the feed tube 26 and installed. At this time, the top block 36 will lift the stopper 34, so that the inner cavity of the ash storage bin 27 is connected with the inner cavity of the feed tube 26 again, and then cold ash can be provided to the furnace shell 5 again.
