Description

Technical Field

[0001] The present invention relates to the technical field of metal recovery, and more specifically, to a device for sorting and recovering waste slag from non-ferrous metal smelting. Background Art

[0002] In the process of non-ferrous metal smelting, especially aluminum smelting, a large amount of waste slag is generated. These waste slags not only contain unutilized metal resources, but also may pollute the environment. Therefore, effective sorting and recycling of aluminum smelting waste slag can not only improve resource utilization, but also reduce environmental pollution. It has important economic and environmental significance. At present, when recycling the waste slag generated in the aluminum smelting process, it is usually necessary to go through pretreatment, magnetic separation, wind separation and other steps. Among them, magnetic separation and wind separation require the use of special recovery equipment.

[0003] When recycling aluminum-containing waste slag, the waste slag is first crushed, and then the crushed waste slag is screened and filtered to screen out large particles and small particles and retain large particles (large particles contain more aluminum). The large particles of waste slag are then magnetically separated to remove ferromagnetic impurities in the waste slag, such as iron filings, steel slag, etc. Finally, the large particles of waste slag after magnetic separation are separated by wind through a fan. Since the density of aluminum is relatively small, lighter aluminum particles (or particles containing aluminum) may be blown into the collection device by wind, while heavier impurities remain in place.

[0004] However, the current air separation recovery device does not fully recover the aluminum-containing particles. The current air separation operation is: the waste slag particles are dropped from a high place, and the fan is on the side of the path where the waste slag particles fall, and the fan blows air to the waste slag particles to separate the aluminum-containing particles from other impurity particles; because the current device can only air separate the waste slag particles once, some aluminum-containing particles are not blown away in time, so that the aluminum-containing particles are not completely air-separated and recovered, and when the current device performs magnetic separation on the waste slag particles, the magnetic separation structure needs to be cleaned from time to time to clean the iron substances from the magnetic separation structure before continuing the magnetic separation.

DETAILED DESCRIPTION

[0032] 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.

[0033] Reference Figure 1 - Fig.10 A non-ferrous metal smelting waste slag sorting and recovery device comprises a fan 1, a first air outlet shell 2 fixedly connected to the fan 1 through a connecting pipe, and a collecting box 3, wherein the collecting box 3 is provided with a first collecting port 301, and further comprises:

[0034] A secondary air separation component is arranged on the collection box 3 for secondary air separation of aluminum-containing particles. The secondary air separation component includes a first connection membrane 11 for receiving waste slag particles and having elasticity. A baffle 12 is fixedly connected to the collection box 3. A pulling elastic component is provided on the collection box 3 for causing the first connection membrane 11 to continuously deform and bounce up. An L-shaped plate 4 is fixedly connected to the bottom of the collection box 3. A flat plate 5 is fixedly connected to the top of the L-shaped plate 4.

[0035] When in use, the waste slag produced by aluminum smelting is first crushed and screened to separate large particles and small particles. The large particles contain more aluminum, and the large particles of waste slag particles are retained. The large particles of aluminum-containing waste slag are evenly laid on the conveyor belt 7, and the drive shaft 6 and the conveyor belt 7 are driven by the driving component to run. The conveyor belt 7 can transport aluminum-containing waste slag particles. When the waste slag particles pass through the magnetic separation component, the magnetic separation component can absorb and remove the iron particles in the waste slag particles, and the iron particles are recycled. The remaining waste slag particles will be transported to the other end by the conveyor belt 7 and fall freely. The fan 1 is started, and the fan 1 blows horizontal wind through the first air outlet shell 2. The freely falling waste slag particles will pass through the air outlet area of ​​the first air outlet shell 2. The wind can select the waste particles. Since the aluminum-containing particles are lighter, they will be blown to a farther position by the wind. The wind will blow the aluminum-containing particles to the top of the first collecting port 301, and the aluminum-containing particles will be collected in the collecting box 3, while the heavier aluminum-free particles will not be blown to a farther distance. The heavier particles will fall on the first connecting membrane 11 and bounce back, and undergo secondary air selection through the secondary air selection component. During the secondary air selection process, the pulling and rebounding component can continuously deform and reset the first connecting membrane 11. The sudden reset of the first connecting membrane 11 after deformation will bounce the waste particles on the first connecting membrane 11 to a higher height. The higher the waste particles bounce, the more disorderly they will fall subsequently, which is more conducive to secondary air selection.

[0036] Reference Figure 2 and Figure 3 The secondary air separation component also includes a connecting pipe 8 fixedly connected to the connecting pipe, one end of the connecting pipe 8 is fixedly connected to a second air outlet shell 9, a second collecting port 302 is opened on the collecting box 3, the first connecting membrane 11 is located directly above the second collecting port 302 and is inclined, and a first fixing frame 10 is fixedly connected to the first connecting membrane 11; the waste slag particles after being air-selected by the wind blown out of the first air outlet shell 2 fall onto the first connecting membrane 11, the waste slag particles will bounce to a certain height, and the bounced waste slag particles may also be caught by the first air outlet shell 2 The blown wind can blow some of the missed aluminum-containing particles into the collection box 3 again. Since the first connecting membrane 11 is in an inclined state, most of the bounced waste particles will bounce to one side of the first connecting membrane 11 and continue to fall freely. The wind blown out by the second air outlet shell 9 is also horizontal. The wind there can perform secondary air separation on the waste particles, and blow the aluminum-containing particles that are not completely separated by air separation to the second collecting port 302, so as to achieve sufficient air separation of the waste particles. The remaining waste particles are not blown into the collection box 3 by the wind, and the aluminum-containing particles are relatively less.

[0037] Reference Figure 3 and Figure 4The elastic pulling assembly includes a first rotating shaft 13 rotatably connected to the collection box 3 through a fixed plate, one end of the first rotating shaft 13 is fixedly connected to a first sprocket 14, one end of one of the transmission shafts 6 is fixedly connected to a second sprocket 15 through a connecting shaft, the first sprocket 14 and the second sprocket 15 are connected by a first chain 16, the outer wall of the first rotating shaft 13 is provided with a rotating disk 17, an annular groove 18 is provided on the rotating disk 17, a first connecting rope 19 is fixedly connected between the first connecting film 11 and the annular groove 18, a slot 20 is provided in the rotating disk 17, and a slot 20 is provided on the first rotating shaft 13. There is a vertical slot 21, a spring 22 is fixed in the vertical slot 21, a round block 23 is fixed at one end of the spring 22, a plug 24 inserted in the slot 20 is fixed on the round block 23, an L-shaped rod 25 is fixed on the round block 23, a fixing ring 26 is fixed to the collection box 3 through the L-shaped column, and one end of the L-shaped rod 25 abuts against the inner wall of the fixing ring 26; during the continuous operation of the transmission shaft 6 and the conveyor belt 7, the transmission shaft 6 drives the first rotating shaft 13 to rotate through the second sprocket 15, the first chain 16 and the first sprocket 14, and the first rotating shaft 13 drives the rotating disk 17 to rotate through the plug 24 and the slot 20, and the rotating disk 17 rotates. The rotation of the movable plate 17 can wrap the first connecting rope 19 in the annular groove 18, and the first connecting rope 19 pulls the first connecting film 11 to deform, and the first rotating shaft 13 drives the L-shaped rod 25 to rotate on the inner wall of the fixing ring 26. When the first rotating shaft 13 rotates half a circle, that is, the L-shaped rod 25 rotates half a circle on the inner wall of the fixing ring 26, the fixing ring 26 presses the L-shaped rod 25 into the first rotating shaft 13, and the L-shaped rod 25 drives the round block 23 to move, the spring 22 is compressed, and the round block 23 drives the plug 24 to leave the slot 20. Under the elastic force of the first connecting film 11, the first connecting film 11 is suddenly reset, and the first connecting film 11 is connected to the first connecting film 11. The rope 19 drives the rotating disk 17 to reset, and the first rotating shaft 13 continues to drive the L-shaped rod 25 and the plug post 24 to rotate, until the plug post 24 is inserted into the slot 20 again under the action of the spring 22, and the first rotating shaft 13 can continue to drive the rotating disk 17 to rotate, so as to realize the continuous deformation and sudden reset of the first connecting membrane 11. The continuous and sudden reset of the first connecting membrane 11 can make the waste particles dropped on the first connecting membrane 11 be bounced up, on the one hand, to prevent the waste particles from being trapped on the first connecting membrane 11, and on the other hand, to make the first connecting membrane 11 have a greater bounce force, so that the waste particles bounce higher, thereby making the waste particles fall more disorderly.

[0038] Reference Figure 5The fixing ring 26 includes a locking section 2601 and a releasing section 2602. One end of the L-shaped rod 25 abuts against the locking section 2601. The distance between the locking section 2601 and the center axis of the first rotating shaft 13 is greater than the distance between the releasing section 2602 and the center axis of the first rotating shaft 13. When the first rotating shaft 13 drives the rotating disk 17 and the L-shaped rod 25 to rotate, one end of the L-shaped rod 25 slides in the locking section 2601. When one end of the L-shaped rod 25 enters the releasing section 2602, since the distance between the locking section 2601 and the center axis of the first rotating shaft 13 is greater than the distance between the releasing section 2602 and the center axis of the first rotating shaft 13, the locking section 2601 is in contact with the locking section 2601. 2 to the central axis of the first rotating shaft 13, the release section 2602 can press the L-shaped rod 25 into the first rotating shaft 13, so that the plug 24 leaves the slot 20, and the lock between the first rotating shaft 13 and the rotating disk 17 is released. The rotating disk 17 can be reset under the action of the first connecting film 11, and the first rotating shaft 13 continues to drive one end of the L-shaped rod 25 to slide on the release section 2602. When one end of the L-shaped rod 25 re-enters the locking section 2601, the plug 24 is re-inserted into the slot 20 under the action of the spring 22, so that the first rotating shaft 13 and the rotating disk 17 are locked again.

[0039] Reference Figure 2 and Figure 3 , the collecting box 3 is fixed with two fixing rods 27, the fixing rods 27 are fixed with a second fixing frame 28, the first fixing frame 10 is fixed with the second fixing frame 28, the second fixing frame 28 is fixed with a second connecting film 29, the second connecting film 29 is elastic and horizontal, and a second connecting rope 30 is fixed between the second connecting film 29 and the annular groove 18; in the process of free fall of the waste slag particles from the conveyor belt 7, some of the lighter aluminum-containing particles are directly blown into the collecting box 3, and some of the aluminum-containing particles are blocked by other particles and are affected by the wind. The force is small, resulting in that the aluminum-containing particles will neither fall onto the first connecting film 11 nor fall into the collecting box 3, but will fall onto the second connecting film 29 in a horizontal state. When the first rotating shaft 13 drives the rotating disk 17 to rotate, the rotating disk 17 pulls the first connecting film 11 to deform and suddenly reset and bounce back through the first connecting rope 19. The rotating disk 17 can also pull the second connecting film 29 to deform and suddenly reset and bounce back through the second connecting rope 30, and the aluminum-containing particles on the second connecting film 29 will be bounced up. The wind can blow the aluminum-containing particles into the collecting box 3.

[0040] Reference Figure 6 and Figure 7The magnetic separation assembly includes two vertical plates 31 fixedly connected to the flat plate 5, and the two vertical plates 31 are both rotatably connected to the second rotating shafts 32, and a rotating shaft 33 is fixedly connected between the two second rotating shafts 32.

Connection; during the operation of the conveyor belt 7, the transmission shaft 6 drives the second rotating shaft 32 to rotate through the third sprocket 36, the fourth sprocket 37 and the second chain 38, the second rotating shaft 32 drives the rotating shaft 33 to rotate, and the rotating shaft 33 drives the fixed sleeve 34 to rotate. Since an electromagnetic rod 47 is provided in the rotating shaft 33, the iron particles in the waste slag particles passing through the rotating shaft 33 are adsorbed on the surface of the fixed sleeve 34. Since the fixed sleeve 34 rotates, the fixed sleeve 34 can adsorb more iron particles. Since the two-way thread 35 is provided, the two-way thread 35 increases the surface area of ​​the fixed sleeve 34, so that the fixed sleeve 34 can adsorb more iron particles.

[0041] Reference Figure 7 and Figure 8 The flat plate 5 is provided with a scraping and collecting assembly for scraping and collecting the iron particles adsorbed on the fixed sleeve 34. The scraping and collecting assembly includes a scraping block 39 arranged on the outer wall of the fixed sleeve 34. The scraping block 39 is fixedly connected with a slider 40.

[0042] Reference Figure 7 and Fig. 9A receiving piece 44 is rotatably connected to one side wall of the collecting groove 43, one end of the receiving piece 44 is lower than the corresponding end of the scraper block 39 and contacts the outer wall of the fixed sleeve 34, the receiving piece 44 can only rotate upward in one direction and is inclined, and a plurality of elastic connecting ribs 45 are fixedly connected between the receiving piece 44 and the collecting groove 43; after the fixed sleeve 34 adsorbs the iron particles, the iron particles adhere to the surface of the fixed sleeve 34, when the fixed sleeve 34 moves to the top of the receiving piece 44 with the iron particles, the receiving piece 44 is compressed and rotated, and the connecting rib 45 is stretched. After the iron particles pass through, the receiving piece 44 is reset under the action of the connecting rib 45, and the receiving piece 44 will not affect the collection of the iron particles, and the iron particles scraped off by the scraper block 39 will be guided into the collecting groove 43 by the receiving piece 44.

[0043] Reference Fig.10 A cavity 46 is provided in the rotating shaft 33, and the electromagnetic rod 47 is located in the cavity 46. A mounting plate 48 is fixedly connected to the electromagnetic rod 47, and a third rotating shaft 49 is fixedly connected to the mounting plate 48.

[0044] Working principle: When in use, the waste slag produced by aluminum smelting is first crushed and screened to separate large particles and small particles. The large particles contain more aluminum, and the large particles of waste slag particles are retained. The large particles of aluminum-containing waste slag are evenly laid on the conveyor belt 7, and the drive shaft 6 and the conveyor belt 7 are driven by the drive component to run. The conveyor belt 7 can transport aluminum-containing waste slag particles. When the waste slag particles pass through the magnetic separation component, the magnetic separation component can absorb and remove the iron particles in the waste slag particles, and the iron particles are recycled. The remaining waste slag particles will be transported to the other end by the conveyor belt 7 and fall freely. Start the fan 1, and the fan 1 blows horizontal wind through the first air outlet shell 2. The freely falling waste slag particles will pass through the air outlet of the first air outlet shell 2. In the area, the wind can select the waste slag particles. Since the aluminum-containing particles are lighter, the aluminum-containing particles will be blown to a farther position by the wind. The wind will blow the aluminum-containing particles to the top of the first collecting port 301, and the aluminum-containing particles will be collected in the collecting box 3, while the heavier aluminum-free particles will not be blown to a farther distance. The heavier particles will fall on the first connecting membrane 11 and bounce up, and undergo secondary air selection through the secondary air selection component. During the secondary air selection process, the pulling and elastic component can continuously deform and reset the first connecting membrane 11. The sudden reset of the first connecting membrane 11 after deformation will bounce the waste slag particles on the first connecting membrane 11 to a higher height. The higher the waste slag particles bounce up, the more disorderly they will fall later, which is more conducive to secondary air selection.

[0045] The waste particles that have been air-selected by the wind blown out of the first air outlet shell 2 fall onto the first connecting membrane 11, and the waste particles will bounce to a certain height. The bounced waste particles may be blown by the wind blown out of the first air outlet shell 2, and some of the missed aluminum-containing particles can be blown into the collecting box 3 again. Since the first connecting membrane 11 is in an inclined state, most of the bounced waste particles will bounce to one side of the first connecting membrane 11 and continue to fall freely. The wind blown out of the second air outlet shell 9 is also in a horizontal direction. The wind there can perform secondary air selection on the waste particles, and blow the aluminum-containing particles that have not been completely air-selected and separated to the second collecting port 302, so as to achieve sufficient air selection of the waste particles. The remaining waste particles are not blown into the collecting box 3 by the wind, and the aluminum-containing particles are relatively small.

[0046] During the continuous operation of the transmission shaft 6 and the conveyor belt 7, the transmission shaft 6 drives the first rotating shaft 13 to rotate through the second sprocket 15, the first chain 16 and the first sprocket 14. The first rotating shaft 13 drives the rotating disk 17 to rotate through the plug column 24 and the slot 20. The rotation of the rotating disk 17 can wrap the first connecting rope 19 in the annular groove 18. The first connecting rope 19 pulls the first connecting film 11 to deform. The first rotating shaft 13 drives the L-shaped rod 25 to rotate on the inner wall of the fixing ring 26. When the first rotating shaft 13 rotates half a circle, that is, the L-shaped rod 25 rotates half a circle on the inner wall of the fixing ring 26, the fixing ring 26 will press the L-shaped rod 25 into the first rotating shaft 13, and the L-shaped rod 25 drives the round block 23 to move. The spring 22 is compressed, and the round block 23 drives the plug column 24 to leave the slot 20. , under the elastic force of the first connecting film 11, the first connecting film 11 suddenly resets, and the first connecting film 11 drives the rotating disk 17 to reset through the first connecting rope 19, and the first rotating shaft 13 continues to drive the L-shaped rod 25 and the plug post 24 to rotate, until the plug post 24 is inserted into the slot 20 again under the action of the spring 22, and the first rotating shaft 13 can continue to drive the rotating disk 17 to rotate, so as to realize the continuous deformation and sudden reset of the first connecting film 11. The continuous and sudden reset of the first connecting film 11 can make the waste particles dropped on the first connecting film 11 be bounced up, on the one hand, preventing the waste particles from being stranded on the first connecting film 11, and on the other hand, making the first connecting film 11 have a greater bounce force, so that the waste particles bounce higher, so that the waste particles fall more disorderly;

[0047] When the first rotating shaft 13 drives the rotating disk 17 and the L-shaped rod 25 to rotate, one end of the L-shaped rod 25 slides on the locking section 2601. When one end of the L-shaped rod 25 enters the releasing section 2602, since the distance from the locking section 2601 to the central axis of the first rotating shaft 13 is greater than the distance from the releasing section 2602 to the central axis of the first rotating shaft 13, the releasing section 2602 can press the L-shaped rod 25 into the first rotating shaft 13, so that the plug post 24 leaves the slot 20, and the lock between the first rotating shaft 13 and the rotating disk 17 is released. The rotating disk 17 can be reset under the action of the first connecting membrane 11, and the first rotating shaft 13 continues to drive one end of the L-shaped rod 25 to slide on the releasing section 2602. When one end of the L-shaped rod 25 re-enters the locking section 2601, under the action of the spring 22, the plug post 24 is reinserted into the slot 20, so that the first rotating shaft 13 and the rotating disk 17 are locked again.

[0048] During the free fall of the waste slag particles from the conveyor belt 7, some of the lighter aluminum-containing particles are directly blown into the collection box 3, and some of the aluminum-containing particles are blocked by other particles and are subject to less wind force, resulting in that these aluminum-containing particles will neither fall onto the first connecting film 11 nor fall into the collection box 3, but will fall onto the second connecting film 29 in a horizontal state. When the first rotating shaft 13 drives the rotating disk 17 to rotate, so that the rotating disk 17 pulls the first connecting film 11 to deform and suddenly reset and bounce up through the first connecting rope 19, the rotating disk 17 can also pull the second connecting film 29 to deform and suddenly reset and bounce up through the second connecting rope 30, so that the aluminum-containing particles on the second connecting film 29 are bounced up, and the wind can blow these aluminum-containing particles into the collection box 3;

[0049] During the operation of the conveyor belt 7, the transmission shaft 6 drives the second rotating shaft 32 to rotate through the third sprocket 36, the fourth sprocket 37 and the second chain 38, the second rotating shaft 32 drives the rotating shaft 33 to rotate, and the rotating shaft 33 drives the fixed sleeve 34 to rotate. Since the rotating shaft 33 is provided with an electromagnetic rod 47, the iron particles in the waste slag particles passing through the rotating shaft 33 are adsorbed on the surface of the fixed sleeve 34. As the fixed sleeve 34 rotates, the fixed sleeve 34 can adsorb more iron particles. Since the bidirectional thread 35 is provided, the bidirectional thread 35 increases the surface area of ​​the fixed sleeve 34, so that the fixed sleeve 34 can adsorb more iron particles.

[0050] During the rotation of the fixed sleeve 34, the scraper block 39 reciprocates on the fixed sleeve 34 under the action of the slider 40 and the bidirectional thread 35. The slider 40 can scrape out the iron particles in the bidirectional thread 35, and the scraper block 39 can scrape off the iron particles on the fixed sleeve 34. The iron particles are scraped into the collecting grooves 43 on both sides, so that the fixed sleeve 34 can continuously collect iron particles. The scraper block 39 continuously scrapes and cleans the fixed sleeve 34, and the guide block 42 can push away the iron particles in the collecting groove 43.

[0051] After the fixed sleeve 34 absorbs the iron particles, the iron particles adhere to the surface of the fixed sleeve 34. When the fixed sleeve 34 moves to the top of the receiving sheet 44 with the iron particles, the receiving sheet 44 is compressed and rotated, and the connecting ribs 45 are stretched. After the iron particles pass through, the receiving sheet 44 is reset under the action of the connecting ribs 45. The receiving sheet 44 will not affect the collection of the iron particles. The iron particles scraped off by the scraping block 39 will be guided by the receiving sheet 44 to the collection channel 43.

[0052] During the rotation of the rotating shaft 33 and the fixed sleeve 34, the electromagnetic rod 47 is always located at the lower position of the cavity 46, so that the fixed sleeve 34 is close to the conveyor belt 7 and has a larger magnetic force, which is convenient for adsorbing the iron particles in the waste slag particles, while the magnetic force above the fixed sleeve 34 is smaller, so that the scraper block 39 can easily scrape off the iron particles.
