Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy smelting, in particular to an aluminum ash separation device for aluminum liquid used in aluminum ingot production. Background Art

[0002] Aluminum ash is an inevitable product of the aluminum alloy smelting process, which contains a certain amount of metallic aluminum, so it has the value of recycling and reuse. In order to extract this metallic aluminum, the usual practice is: put the hot aluminum ash into the ash frying pan and stir it thoroughly; during the stirring process, the metallic aluminum in the hot aluminum ash will gradually settle to the bottom of the pan due to its liquid properties, and then flow into the collection cylinder placed under the bottom of the pan in advance; when the metallic aluminum is collected, the remaining ash is smoothly discharged through the special slag discharge port of the ash frying pan, thereby achieving effective separation and recovery of metallic aluminum in the aluminum ash.

[0003] For example, a Chinese patent discloses an aluminum liquid and aluminum ash separation device (CN218642796U), which includes a frame, a pot body, a motor, a stirring mechanism, a bottom cover, an opening and closing mechanism and a material receiving trolley; the pot body is connected to the frame, and a feeding channel is provided on the pot body; the stirring mechanism is connected to the pot body, and the motor is driven and connected to the stirring mechanism; one end of the bottom cover is rotatably connected to the bottom of the pot body, and the other end is connected to the pot body through the opening and closing mechanism, and an aluminum liquid outlet is provided on the bottom cover, and the material receiving trolley is located at the bottom of the aluminum liquid outlet; the pot body is bowl-shaped, and the upper and lower ends of the pot body are open; a support frame is connected to the frame, and the feeding channel is obliquely connected to the support frame, and the bottom end of the feeding channel is located above the upper opening of the pot body.

[0004] The above-mentioned prior art has the following shortcomings: when the aluminum liquid is collected and the ash is removed, the L-shaped rod needs to be rotated, the L-shaped rod pulls the locking rod out of the locking groove, and then the pull rod is pulled to open the bottom cover to pour out the ash at the bottom of the pot body. Afterwards, the bottom cover needs to be closed again, resulting in a long downtime for cleaning the ash, which affects the aluminum ash separation efficiency of the equipment.

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0046] Embodiment 1:

[0047] like Figures 1 to 3 As shown, the present invention provides an aluminum ash separation device for aluminum liquid used in aluminum ingot production, wherein the bottom of the shell 7 is provided with an annular collecting groove 3, and the pot body 1 is installed at the center hole of the annular collecting groove 3, and the pot body 1, the annular collecting groove 3 and the shell 7 constitute a closed cavity. The shell 7 is provided with a feed hopper 71, a smoke outlet pipe 72 and an observation window; aluminum ash is poured into the pot body 1 through the feed hopper 71; the smoke outlet pipe 72 is connected to a smoke dust treatment device to avoid waste gas pollution; the treatment of aluminum ash in the pot body 1 can be observed through the observation window.

[0048] Recombination Figure 4As shown, a liquid outlet 11 is provided at the bottom of the pot body 1, and a stirring device 5 is installed in the pot body 1, and the stirring device 5 is driven by a driving assembly 4. The stirring device 5 has two functions, one of which is to stir the aluminum ash in the pot body 1 so that the aluminum liquid therein flows out from the liquid outlet 11 and is collected by the material receiving cylinder 62 below the pot body 1; the second function is to lift the processed ash residue in the pot body 1 to the annular collection tank 3 outside the pot body 1.

[0049] In this embodiment, the stirring device 5 includes a rotating shaft 52 located at the axial center of the pot body 1, and a stirring blade assembly 51 is fixed at the lower end of the rotating shaft 52. The stirring blade assembly 51 is a combined stirring structure, including a pair of auger blades 511 located in the outer ring part and a plurality of stirring rods 512 located in the inner ring part. The outer periphery of the auger blade 511 is in contact with the inner wall of the pot body 1, and the upper end of the auger blade 511 is higher than the upper edge of the pot body 1 and is fixed with a guide plate 513. The stirring rod 512 connects the inner periphery of the auger blade 511 and the rotating shaft 52.

[0050] When the rotating shaft 52 rotates forward, the rotating shaft 52 drives the stirring rod 512 to stir the aluminum ash in the pot body 1, so that the aluminum liquid therein flows out from the liquid outlet 11; when the rotating shaft 52 rotates reversely, the auger blade 511 relies on the centrifugal force to lift the ash in the pot body 1 upward, and the guide plate 513 at the upper end then guides the ash on the auger blade 511 to the annular collecting groove 3 outside the pot body 1, thereby completing the cleaning work of the pot body 1.

[0051] Combination Figures 2 to 4 As shown, the annular collecting trough 3 is used to receive the ash cleaned out from the pot body 1. A slag outlet 31 is provided at the bottom of the annular collecting trough 3, and an ash receiving cylinder is provided below the slag outlet 31. The scraper 2 is driven by the driving assembly 4 and is installed in the annular collecting trough 3 in a manner of rotating along the axis of the annular collecting trough 3. When the scraper 2 slides, the scraper 2 can push the ash in the annular collecting trough 3 to the slag outlet 31; a plurality of through holes are provided on the scraper 2 to reduce the resistance of the scraper 2, and the ash in the annular collecting trough 3 can be completely cleaned by rotating for multiple circles.

[0052] Combination Figure 4 and Figure 5 As shown, the driving component 4 is used to drive the scraper 2 and the stirring device 5, and has two driving states: forward and reverse. When the driving component 4 is in the first driving state, the driving component 4 alone drives the rotating shaft 52 to reverse at a faster speed. When the driving component 4 is in the second driving state, the driving component 4 drives the rotating shaft 52 and the scraper 2 to rotate forward at a slower speed.

[0053] In this embodiment, the driving assembly 4 includes a gear box fixed on the housing 7, in which a power input shaft 41 arranged parallel to the rotating shaft 52 is rotatably installed, and the upper end of the power input shaft 41 is connected to the driving motor through a flange. A rotating drum 42 is rotatably mounted on the rotating shaft 52, and the lower end of the rotating drum 42 is connected to the scraper 2 through an "L"-shaped support rod 21.

[0054] The first transmission gear mechanism 43 includes a large gear I 431 and a small gear I 432 meshing with each other. The large gear I 431 is fixed on the power input shaft 41, and the small gear I 432 is fixed on the rotating shaft 52. The power of the power input shaft 41 is transmitted through the large gear I 431 and the small gear I 432 to generate a speed-increasing effect.

[0055] The second transmission gear mechanism 44 includes a pinion II 441 and a large gear II 442 that mesh with each other. The pinion II 441 is fixed on the power input shaft 41, and the large gear II 442 is fixed on the drum 42. The power of the power input shaft 41 is transmitted through the pinion II 441 and the large gear II 442 to produce a deceleration effect. In this way, under the action of the first transmission gear mechanism 43 and the second transmission gear mechanism 44, the drum 42 produces a two-stage deceleration relative to the shaft 52. The purpose is: when the drive assembly 4 drives the shaft 52 to rotate forward for stirring, the speed of the scraper 2 at the lower end of the drum 42 is reduced, so that the scraper 2 can complete the cleaning operation of the annular collection tank 3 at a slower speed. The pinion II 441 in the second transmission gear mechanism 44 is a ratchet. The purpose is: when the drive assembly 4 drives the shaft 52 to rotate backward, the power of the power input shaft 41 cannot be transmitted to the drum 42, so that the drum 42 is kept in a stationary state.

[0056] Working principle:

[0057] Pour aluminum ash into the pot body 1 through the feed hopper 71;

[0058] The driving motor rotates forward, the power input shaft 41 drives the rotating shaft 52 to rotate forward through the first transmission gear mechanism 43, and the stirring rod 512 drives the stirring rod 512 to stir the aluminum ash in the pot body 1, so that the aluminum liquid therein flows out from the liquid outlet 11 and is collected by the material receiving cylinder 62 below the pot body 1;

[0059] During the above stirring operation, the power input shaft 41 drives the rotating drum 42 through the second transmission gear mechanism 44, and the rotating drum 42 drives the scraper 2 below to push the ash (generated by the previous operation) in the annular collecting trough 3 to the ash outlet 31 at a slower speed, and is collected by the ash receiving drum;

[0060] After the aluminum liquid is collected, the drive motor reverses at a faster speed, and the power input shaft 41 drives the rotating shaft 52 to reverse through the first transmission gear mechanism 43. Under the action of the ratchet in the second transmission gear mechanism 44, the power of the power input shaft 41 cannot be transmitted to the rotating drum 42, and the rotating drum 42 remains stationary; when the rotating shaft 52 reverses, the auger blades 511 rely on centrifugal force to lift the ash in the pot body 1 upward, and then the guide plate 513 at the upper end guides the ash to the annular collection groove 3 outside the pot body 1. After completion, the next round of aluminum ash treatment operation begins.

[0061] Embodiment 2:

[0062] Based on the above embodiment 1, combined with the attached Figure 6 As shown, in order to facilitate the maintenance of the pot body 1, the annular collecting tank 3 is elevated by the legs 8. A sink is provided in the middle of the foundation 9, and a lifting platform 6 is installed in the sink. A support 61 is fixed on the lifting platform 6, and the pot body 1 is placed on the support 61. A material receiving tube 62 is placed in the middle of the support 61.

[0063] When the lifting platform 6 is in a high position, the pot body 1 is inserted into the annular collecting groove 3 from below, and the upper edge of the pot body 1 is kept higher than the upper edge of the annular collecting groove 3. When the lifting platform 6 is in a low position, the pot body 1 is downwardly separated from the annular collecting groove 3, and the inside of the pot body 1 is convenient for maintenance.

[0064] The aluminum ash separation device of the present invention has a stirring blade assembly that is divided into two functional parts: lifting and stirring. When the stirring blade assembly rotates forward, it can effectively stir the material in the pot body; and when the stirring blade assembly rotates reversely, it can sweep the material in the pot body into the external annular collection trough. Such a design not only improves the ash cleaning efficiency, but also reduces the downtime of the equipment, thereby improving the overall production efficiency. In addition, the drive assembly is specially configured with a one-way transmission mechanism, which cleverly utilizes the power generated by the forward rotation of the stirring blade assembly, so that the scraper can automatically discharge the material in the annular collection trough. In this way, stirring and cleaning can be carried out simultaneously without the need for additional time and manpower, further improving the processing efficiency of the aluminum ash separation device.

[0065] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
