Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy production, and in particular to a device for recycling forged aluminum alloy scraps and a process thereof. Background Art

[0002] During the processing of aluminum alloys, a large amount of debris will be generated. If these debris are directly discarded, it will not only cause a waste of resources, but also may cause environmental pollution. Therefore, how to effectively collect, remove impurities and re-smelt these debris has become a problem that needs to be solved urgently.

[0003] Application No. CN202110624392.9 discloses a device for recycling and processing aluminum alloy scraps, including a U-shaped support frame, a drying box is rotatably installed on the upper end of one side of the U-shaped support frame, and one end of the drying box can be movably clamped on the U-shaped support frame; under the coordinated action of the mixing mechanism, the connecting pipe and the annular exhaust pipe, the present invention can ensure the mixing uniformity of the medicine liquid inside the flue gas treatment box, thereby providing a guarantee for the uniform mixing reaction of the flue gas and the medicine liquid, and then ensuring the treatment effect of the flue gas; under the drive of the second motor, the present invention, in conjunction with the use of the first rotating rod, the snake-shaped stirring rod and the drying lamp, can shorten the time required for complete drying of the aluminum alloy scraps, thereby effectively improving the drying efficiency of the aluminum alloy scraps; through the coordinated use of the first motor, the screw rod, the moving block and the lifting rod, the present invention can adjust the drying box to an inclined state, thereby facilitating the export of the dried aluminum alloy scraps out of the drying box.

[0004] Based on the search of the above patents and the application of the existing forged aluminum alloy scrap recycling device, it is understood that the forged aluminum alloy scrap recycling is to pour the aluminum alloy scraps into a rotary kiln for baking to obtain dry aluminum alloy scraps, and further remove impurities in the melt through a refining process to improve the purity of the aluminum alloy. Finally, the refined aluminum alloy melt is cast into a mold, and after cooling and solidification, a recycled aluminum alloy product can be obtained. However, there are still the following deficiencies in the aluminum alloy scrap recycling link:

[0005] 1. During the processing or recycling process of aluminum alloy debris, an oxide film is easily formed on the surface and various impurities are attached. Traditional cleaning methods are often difficult to completely remove these pollutants, resulting in a decrease in product quality during subsequent processing. In addition, traditional cleaning methods usually rely on static immersion and simple stirring, which cannot effectively achieve comprehensive overturning and uniform cleaning of aluminum alloy debris, resulting in low cleaning and immersion efficiency, long time consumption and poor results.

[0006] 2. Aluminum alloy scraps are often mixed with iron impurities, which will affect the purity and performance of the product during subsequent processing. However, the existing technology lacks efficient and flexible magnetic separation devices, making it difficult to effectively remove these iron impurities.

[0007] 3. During the transportation of aluminum alloy chips, the surface of the conveying parts is prone to absorb debris and residues, which not only affects the transportation efficiency, but may also damage subsequent processing equipment and shorten the service life of the equipment.

[0008] Therefore, in view of this, the existing structure and defects are studied and improved, and a forged aluminum alloy chip recovery and recycling device and process are provided, in order to achieve a more practical purpose. Summary of the invention

[0009] In order to solve the above technical problems, the present invention provides a forged aluminum alloy scrap recycling device and a process thereof, so as to solve the problems that during the processing or recycling of the existing aluminum alloy scraps, an oxide film is easily formed on the surface and various impurities are attached, and the traditional cleaning method is often difficult to completely remove these pollutants, resulting in a decrease in product quality during the subsequent processing. In addition, the traditional cleaning method usually relies on static immersion and simple stirring, and cannot effectively achieve comprehensive overturning and uniform cleaning of the aluminum alloy scraps, resulting in low cleaning and immersion efficiency, long time consumption and poor effect. The prior art lacks efficient and flexible magnetic separation devices, making it difficult to effectively remove these iron impurities, and during the transportation of the aluminum alloy scraps, the surface of the conveying parts is easily adsorbed with debris and residues, which not only affects the transportation efficiency, but also may cause damage to subsequent processing equipment and shorten the service life of the equipment.

The left and right sides of the bidirectional screw are respectively located in the threaded holes of one bidirectional slider. A detachable magnet is provided at each of the lower positions on both sides of each bidirectional slider.

[0014] Further, a cleaning frame is fixedly installed at the middle and lower position at the rear end of the dryer. The cleaning frame is designed in a U shape. Two limiting plates are respectively provided at the left and right sides inside the cleaning frame. The two limiting plates on the same side are both slidably connected to the sliding rods at the lower same side of the scraping frame. Spring members are sleeved on the sliding rods at the lower sides of both sides of the scraping frame. The upper position of the spring member is in contact with the bottom position of the limiting plate. The scraping teeth at the upper end of the scraping frame are distributed in a staggered manner.

[0015] Further, a motor D is fixedly installed at the right side position of the cleaning frame. The rotating shaft of the motor D passes through the lower position inside the cleaning frame. A cam is fixedly installed at each of the left and right sides of the rotating shaft of the motor D. The two cams are respectively in contact with the sliding rods at the lower sides of both sides of the scraping frame.

[0016] Further, a limiting disk is fixedly installed at the middle and lower position at the left side of the cleaning frame. The limiting disk and the motor D are symmetrically designed on the left and right sides of the cleaning frame. The inner wall of the limiting disk is provided with a tooth slot.

[0017] Further, a rotating disk is fixedly installed at the left side position of the rotating shaft of the motor D. The rotating disk is located at the middle position inside the limiting disk. Six limiting claws are rotatably connected to the circumferential surface of the rotating disk. The inner edge positions of the six limiting claws are connected to the rotating disk through springs. When the rotating disk is in a static state, the six limiting claws are in contact with the surface of the rotating disk.

[0018] Further, the cleaning frame is located at the front end position of the winding and unwinding frame. The winding and unwinding frame is located at the lower position behind the conveying member. A blower is fixedly installed at the rear end position at the top of the winding and unwinding frame. Two adjusting heads with adjustable angles are provided at the upper end of the blower.

[0019] The present invention also provides a process for a forging aluminum alloy chip compound regeneration and utilization device, including the following steps:

[0020] 1) Put the aluminum alloy scraps into the feeding bin of the pretreatment rack, then close the valve at the bottom of the feeding bin, put the feeding bin into a proportional 4% sulfuric acid solution and soak it for 120 seconds to remove the surface oxide film and other impurities, then remove the sulfuric acid solution inside the feeding bin through the valve at the bottom and collect it for standby use, add 55°C washing liquid into the feeding bin, soak and clean the aluminum alloy scraps inside the feeding bin, and at the same time start the motor A to drive the bidirectional spiral part to rotate, and the bidirectional spiral part overturns the aluminum alloy scraps inside the feeding bin to improve the cleaning efficiency and soaking efficiency of the aluminum alloy scraps, and then discharge the washing liquid inside the feeding bin through the valve at the bottom of the feeding bin;

[0021] 2) After the water source inside the feeding bin is discharged, open the valve set in the conveying pipe and start the motor B at the same time. The motor B drives the one-way screw to rotate. When the two-way screw rotates, the aluminum alloy chips are centrally transferred to the middle position inside the feeding bin. At this time, the aluminum alloy chips in the middle position of the feeding bin will enter the front end of the conveying pipe, and the aluminum alloy chips will be transferred to the inside of the conveying pipe through the one-way screw. Then, the discharge rack installed in the discharge trough of the conveying pipe will transfer the pre-treated aluminum alloy chips to the upper position of the conveying part, so as to facilitate the subsequent drying process;

[0022] 3) When the conveyor transfers the aluminum alloy chips at the upper position backward, it will pass through the lower position of the bidirectional slider. The magnets set on both sides of the bidirectional slider will magnetically separate the aluminum alloy chips to remove iron impurities. By starting the motor C to drive the bidirectional screw to rotate, the bidirectional screw can move and adjust the opposite positions of the two bidirectional sliders, which is convenient for adjusting the lateral position of the magnet installed on the bidirectional slider. When the aluminum alloy chips are transported above the conveyor, the situation that the magnet is not magnetic enough to absorb some iron materials can be avoided;

[0023] 4) After the conveyor transfers the aluminum alloy chips to the dryer, the drying temperature of the dryer is adjusted to be within the range of 130℃-160℃, and the conveyor speed is controlled at the same time, so that the time for the aluminum alloy chips transported by the conveyor to pass through the dryer is controlled within 50min-70min;

[0024] 5) After the aluminum alloy chips on the conveyor are dried, they will be transferred to the inside of the storage rack through the conveyor. During this period, the wind generated by the fan will blow and cool the end of the conveyor and the inside of the storage rack, and blow away the dust at the same time. The position adjustment of the adjustment head is more convenient for the air outlet adjustment of the fan;

[0025] 6) After the conveyor has finished conveying the aluminum alloy debris, start the motor D, and the shaft of the motor D will synchronously drive the two cams to rotate. The two cams cooperate with the scraper frame slide bar, and the scraper frame slide bar spring cooperates, and the scraper frame makes reciprocating movements up and down. The scraper frame scrapes and cleans the surface of the end of the conveyor to prevent debris from being adsorbed on the conveyor surface and affecting its use;

[0026] 7) If the speed of motor D is too fast, the rotational inertia of motor D will drive the six limiting claws on the outside of the rotating disk to expand until the expanded position of the six limiting claws fits the tooth groove position on the inner wall of the limiting disk for friction, thereby reducing the speed inertia of motor D and adjusting the speed of the scraping frame moving up and down to avoid the scraping frame having too much inertia to scrape off the solidified material of the conveying part, thereby damaging the transmission capacity of the conveying part.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The cleanliness of the aluminum alloy chips was significantly improved by putting them into the feeding bin of the pretreatment rack and soaking them in 4% sulfuric acid solution to remove the surface oxide film and other impurities. Then, 55°C detergent was used for soaking and cleaning, and motor A was started to drive the bidirectional spiral part to rotate to realize the overturning treatment of the aluminum alloy chips, which further enhanced the cleaning efficiency and soaking effect, and laid a good foundation for subsequent treatment.

[0029] 2. The coordinated design of motor B and the one-way screw enables the aluminum alloy chips to be centered and smoothly transferred to the conveying pipe, and then the pre-treated aluminum alloy chips are transferred to the top of the conveying part through the discharge rack, realizing an automated and continuous conveying and pre-treatment process and improving work efficiency.

[0030] 3. A bidirectional slider and a magnet are set above the conveyor to perform magnetic separation on the aluminum alloy chips, which effectively removes iron impurities and improves the purity of the aluminum alloy chips, providing higher quality raw materials for subsequent processing applications. The adjustment design of the bidirectional screw and the bidirectional slider allows the lateral position of the magnet to be flexibly adjusted according to actual needs, thereby enhancing the adaptability and flexibility of the magnetic separation effect.

[0031] 4. The temperature of the dryer is controlled within the range of 130℃-160℃, and the transport speed of the conveyor is precisely controlled to ensure that the aluminum alloy chips stay in the dryer for a moderate time (50min-70min), which not only ensures the drying effect, but also avoids the degradation of material properties caused by over-drying, and significantly improves product quality.

[0032] 5. The fan and the regulating head are used together to purge, cool down and remove dust from the end of the conveyor and the inside of the storage rack, which improves the production environment and reduces the impact of dust on product quality and production equipment.

[0033] 6. Motor D drives the cam to rotate. Combined with the design of the scraping frame, slide bar and spring, the surface of the end of the conveyor can be automatically scraped and cleaned, avoiding the adsorption and solidification of debris, effectively extending the service life of the conveyor. The design of the limiting claw and the limiting disk can automatically adjust the up and down movement speed of the scraping frame, avoiding the situation where the transmission capacity of the conveyor is damaged due to excessive scraping inertia, and further ensuring the stable operation of the equipment.

[0053] Among them, a cleaning rack 3 is fixedly installed at the lower middle position at the rear end of the dryer 2. The cleaning rack 3 is designed in a U shape, and two limiting plates 301 are respectively arranged at the left and right positions inside the cleaning rack 3. The two limiting plates 301 on the same side are both slidably connected to the sliding rods at the lower same side of the scraping rack 302.

Six limiting claws 308 are rotatably connected to the circumferential surface of the rotating disk 307, and the inner edge positions of the six limiting claws 308 are connected to the rotating disk 307 through springs. When the rotating disk 307 is in a static state, the six limiting claws 308 are attached to the surface position of the rotating disk 307.

[0054] Among them, the cleaning rack 3 is located at the front end position of the winding and unwinding rack 4, and the winding and unwinding rack 4 is located at the lower rear position of the conveying member 201. A blower 401 is fixedly installed at the rear end position of the top of the winding and unwinding rack 4. Two angle-adjustable adjusting heads 402 are arranged at the upper end of the blower 401.

[0055] During use:

[0056] Put the aluminum alloy debris into the feeding bin 101 of the pretreatment rack 1, then close the valve at the bottom of the feeding bin 101, and immerse the feeding bin 101 in a 4% sulfuric acid solution in proportion for 120S to remove the surface oxide film and other impurities. Then, drain and collect the sulfuric acid solution inside the feeding bin 101 through the valve at the bottom. Add a 55°C washing solution into the feeding bin 101 to soak and clean the aluminum alloy debris inside the feeding bin 101. At the same time, start the motor A102 to drive the bidirectional spiral member 103 to rotate. The bidirectional spiral member 103 turns over the aluminum alloy debris inside the feeding bin 101 to improve the cleaning efficiency and soaking efficiency of the aluminum alloy debris. Subsequently, drain the washing solution inside the feeding bin 101 through the valve at the bottom of the feeding bin 101.

[0057] After the water source inside the feeding bin 101 is discharged, the valve set in the conveying pipe 104 is opened, and the motor B105 is started at the same time. The motor B105 drives the one-way screw 106 to rotate. When the two-way screw 103 rotates, the aluminum alloy chips are transferred to the middle position inside the feeding bin 101. At this time, the aluminum alloy chips in the middle position of the feeding bin 101 will enter the front end position of the conveying pipe 104, and the aluminum alloy chips are transferred to the inside of the conveying pipe 104 through the one-way screw 106. Then, the discharge rack 107 installed on the discharge trough of the conveying pipe 104 transfers the pre-treated aluminum alloy chips to the position above the conveying member 201, so as to facilitate subsequent drying treatment.

[0058] When the conveyor 201 transfers the aluminum alloy chips at the upper position backward, it will pass through the lower position of the bidirectional slider 206. The magnets 207 arranged on both sides of the bidirectional slider 206 will magnetically separate the aluminum alloy chips to remove iron impurities. By starting the motor C204 to drive the bidirectional screw 205 to rotate, the bidirectional screw 205 can move and adjust the opposite positions of the two bidirectional sliders 206, so as to facilitate the adjustment of the lateral position of the magnet 207 installed on the bidirectional slider 206. When the aluminum alloy chips are transported above the conveyor 201, the situation that the magnet 207 is not magnetic enough and cannot absorb some iron materials can be avoided.

[0059] After the conveyor 201 transfers the aluminum alloy chips to the interior of the dryer 2, the drying temperature of the dryer 2 is adjusted and controlled within the range of 130°C-160°C, and the transport speed of the conveyor 201 is controlled at the same time, so that the time for the aluminum alloy chips transported by the conveyor 201 to pass through the interior of the dryer 2 is controlled within 50min-70min.

[0060] After the aluminum alloy chips on the conveying member 201 are dried, they will be transferred to the inside of the storage rack 4 through the conveying member 201. During this period, the wind force generated by the fan 401 will blow and cool the end of the conveying member 201 and the inside of the storage rack 4, and blow away the dust at the same time. The position adjustment of the adjustment head 402 is more convenient for the air outlet adjustment of the fan 401.

[0061] After the conveying member 201 completes conveying the aluminum alloy debris, the motor D304 is started, and the rotating shaft of the motor D304 will synchronously drive the two cams 305 to rotate. Combined with the cooperation of the two cams 305 and the sliding rod of the scraping frame 302, as well as the cooperation of the sliding rod spring of the scraping frame 302, the scraping frame 302 makes reciprocating movements up and down, and the scraping frame 302 scrapes and cleans the surface position of the end of the conveying member 201 to prevent debris from being adsorbed to the transport surface of the conveying member 201 and affecting its use.

[0062] If the speed of motor D304 is too fast, the rotational inertia of motor D304 will drive the six limiting claws 308 on the outside of the rotating disk 307 to expand until the expanded position of the six limiting claws 308 is in contact with the tooth groove position on the inner wall of the limiting disk 306 for friction, thereby reducing the speed inertia of motor D304 and adjusting the speed of the scraping frame 302 moving up and down to avoid the scraping frame 302 having too much inertia in scraping off the solidified material on the conveying member 201, thereby damaging the transmission capacity of the conveying member 201.

[0063] The above are only specific implementations of the present disclosure, but the protection scope of the present disclosure is not limited thereto, and the protection scope of the present disclosure shall be based on the protection scope of the claims.

10. A process for the forged aluminum alloy scrap recycling device as claimed in claims 1 to 9, comprising the following steps: 1) Aluminum alloy scraps are put into a feeding bin (101) of a pretreatment rack (1), and then the valve at the bottom of the feeding bin (101) is closed, and the feeding bin (101) is placed in a proportional 4% sulfuric acid solution and soaked for 120 seconds to remove the surface oxide film and other impurities, and then the sulfuric acid solution in the feeding bin 1 (01) is discharged through the valve at the bottom and collected for standby use, and then a 55° C. washing liquid is added into the feeding bin (101) to soak and clean the aluminum alloy scraps in the feeding bin (101), and at the same time, a motor A (102) is started to drive a bidirectional screw (103) to rotate, and the bidirectional screw (103) turns over the aluminum alloy scraps in the feeding bin (101), thereby improving the cleaning efficiency and soaking efficiency of the aluminum alloy scraps, and then the washing liquid in the feeding bin (101) is discharged through the valve at the bottom of the feeding bin (101); 2) After the water source inside the feeding bin (101) is discharged, the valve provided on the conveying pipe (104) is opened, and the motor B (105) is started at the same time. The motor B (105) drives the one-way screw (106) to rotate. When the two-way screw (103) rotates, the aluminum alloy chips are centrally transferred to the middle position inside the feeding bin (101). At this time, the aluminum alloy chips in the middle position of the feeding bin 1 (01) enter the front end position of the conveying pipe (104), and the aluminum alloy chips are transferred to the inside of the conveying pipe (104) through the one-way screw (106). Then, the discharge rack (107) installed on the discharge trough of the conveying pipe (104) transfers the pre-treated aluminum alloy chips to the upper position of the conveying member (201) for subsequent drying treatment; 3) When the conveying member (201) transfers the aluminum alloy chips at the upper position backward and conveys them, the conveying member (201) passes through the lower position of the bidirectional slider (206). The magnets (207) arranged on both sides of the bidirectional slider (206) perform magnetic separation on the aluminum alloy chips to remove iron impurities. By starting the motor C (204), the bidirectional screw (205) is driven to rotate. The bidirectional screw (205) can adjust the opposite positions of the two bidirectional sliders (206) to facilitate the adjustment of the lateral position of the magnet (207) installed on the bidirectional slider (206). When the aluminum alloy chips are conveyed above the conveying member (201), the situation that the magnet (207) is not magnetic enough to absorb some iron materials can be avoided; 4) After the conveying member (201) transfers the aluminum alloy scraps to the interior of the dryer (2), the drying temperature of the dryer (2) is adjusted and controlled within the range of 130° C. to 160° C., and the conveying speed of the conveying member (201) is controlled so that the time for the aluminum alloy scraps transported by the conveying member (201) to pass through the interior of the dryer (2) is controlled within 50 min to 70 min; 5) After the aluminum alloy chips on the conveying member (201) are dried, they are transferred to the inside of the storage rack (4) through the conveying member (201). During this period, the wind force generated by the fan (401) is used to blow and cool the end of the conveying member (201) and the inside of the storage rack (4), and the dust is blown away. The position adjustment of the regulating head (402) is more convenient for adjusting the air outlet of the fan (401); 6) After the conveying member (201) has completed conveying the aluminum alloy debris, the motor D (304) is started, and the rotating shaft of the motor D (304) will synchronously drive the two cams (305) to rotate. In combination with the cooperation of the two cams (305) and the sliding rod of the scraping frame (302), and the cooperation of the sliding rod spring of the scraping frame (302), the scraping frame (302) makes a reciprocating movement between the upper and lower positions, and the scraping frame (302) scrapes and cleans the surface position of the end of the conveying member (201) to prevent debris from being adsorbed onto the transport surface of the conveying member (201) and affecting its use; 7) If the rotation speed of the motor D (304) is too fast, the rotation inertia of the motor D (304) will drive the six limiting claws (308) on the outer side of the rotating disk (307) to expand, until the expanded position of the six limiting claws (308) is in contact with the tooth groove position of the inner wall of the limiting disk (306) for friction, thereby reducing the rotation speed inertia of the motor D (304) and adjusting the speed of the scraping frame (302) moving up and down, so as to avoid the scraping frame (302) from scraping away the solidified material on the conveying member (201) with too much inertia, thereby damaging the transmission capacity of the conveying member (201).
