Technical Field

[0001] This utility model belongs to the field of aluminum alloy processing technology, specifically an aluminum alloy processing waste recycling device. Background Technology

[0002] Aluminum alloy processing refers to the process of shaping aluminum alloy raw materials (such as ingots, plates, bars, etc.) into parts or structural components that meet requirements through machining, forming, heat treatment, and other methods. Due to their lightweight, high strength, corrosion resistance, and ease of processing, aluminum alloys are widely used in aerospace, automotive manufacturing, electronic equipment, and building materials industries.

[0003] The recycling of aluminum alloy processing waste has significant economic, environmental, and resource sustainability implications. It is not only a direct means of reducing costs but also a core measure to promote the green transformation of the manufacturing industry. Through efficient recycling, enterprises can achieve a closed loop of "waste reduction-cost reduction-compliance-value enhancement," while contributing to global sustainable development goals.

[0005] Therefore, this utility model provides a waste recycling device for aluminum alloy processing. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 2As shown in the embodiment of this utility model, an aluminum alloy processing waste recycling device includes a filter barrel 1; a negative pressure suction nozzle 11 is connected to the top of the filter barrel 1; a filter screen 12 is installed on the inner side wall of the filter barrel 1; a rotary motor 13 is installed at the bottom of the filter barrel 1; a centrifuge barrel 14 is fixedly connected to the output end of the rotary motor 13; a connecting pipe 15 is connected to the bottom of the centrifuge barrel 14; during operation, the negative pressure suction nozzle 11 is opened and positioned at the location of the aluminum alloy processing tool to adsorb and recycle aluminum alloy waste into the filter barrel 1. After the waste enters the filter barrel 1, the filter screen 12 performs preliminary filtration of the waste. The process filters out some large impurities. After the debris enters the centrifuge tank 14, the rotary motor 13 is turned on to rotate the centrifuge tank 14. Utilizing the density difference between aluminum and impurities, the cutting fluid residue and light contaminants are separated at a speed of 1200-1500 rpm. Finally, the debris enters the next process through the connecting pipe 15. Through the dual filtration setup of the filter screen 12 and the centrifuge tank 14, the aluminum alloy debris entering the filter tank 1 can be finely filtered, reducing the problem of useless impurities mixed with aluminum alloy debris, which would lead to a decrease in the purity of the debris. At the same time, it also reduces the wear and damage to mechanical equipment caused by some impurities, such as iron filings.

[0025] like Figure 2 As shown, multiple magnets 2 are fixed to the inner wall of the centrifuge drum 14; the magnets 2 are evenly arranged in a circular pattern on the inner wall of the centrifuge drum 14; when the debris enters the centrifuge drum 14 after being filtered through the filter screen 12, the magnets 2 will attract magnetic impurities such as iron filings, reducing their mixing with the aluminum alloy debris; through the arrangement of the magnets 2, when the debris enters the centrifuge drum 14 after being filtered through the filter screen 12, the magnets 2 will attract magnetic impurities such as iron filings, reducing their mixing with the aluminum alloy debris; at the same time, the even arrangement of the magnets 2 can distribute the debris evenly on the inner wall of the centrifuge drum 14 during centrifugation, reducing the accumulation and clogging problems that may be caused by uneven distribution of debris.

[0026] like Figure 1 and Figure 3As shown, an air chamber 3 is installed on the top of the filter bucket 1; an air inlet pipe 31 is connected to the side wall of the air chamber 3; multiple exhaust holes 32 are opened at the bottom of the air chamber 3; the exhaust holes 32 are connected to the top of the filter bucket 1; and an exhaust pipe 33 is connected to the side wall of the filter bucket 1. During operation, the air inlet pipe 31 is connected to an air pump, allowing air to enter the air chamber 3 through the air inlet pipe 31 and then enter the filter bucket 1 through the exhaust holes 32. This serves two purposes: firstly, it can blow away non-magnetic debris adhering to the magnets 2 inside the centrifuge bucket 14, reducing their adhesion to the magnets 2; secondly... The system can dry the cutting fluid entering the filter tank 1, reducing its fusion and clumping with the debris. To prevent excessive air pressure inside the filter tank 1, the airflow can be discharged through the exhaust pipe 33. The air chamber 3 can blow away non-magnetic debris adhering to the magnet 2 inside the centrifuge tank 14, reducing its adhesion to the magnet 2 and minimizing waste caused by debris residue and low purity of recycled aluminum. It can also dry the cutting fluid entering the filter tank 1, reducing its fusion and clumping with the debris.

[0027] like Figures 4 to 5 As shown, the connecting pipe 15 is connected to the compression chamber 4; a hydraulic cylinder 41 is installed on the side wall of the compression chamber 4; a telescopic rod 42 is fixedly connected to the output end of the hydraulic cylinder 41; a compression plate 43 is fixedly connected to the end of the telescopic rod 42; the compression plate 43 is hollow; when the debris enters the compression chamber 4 after being filtered, the hydraulic cylinder 41 is opened to drive the telescopic rod 42, thereby pushing the compression plate 43 to compress the aluminum alloy debris entering the compression chamber 4, compressing the loose debris into high-density blocks, which facilitates transportation and subsequent processing; through the setting of the compression chamber 4, loose debris can be compressed into high-density blocks, which reduces the volume due to compression, making transportation easier and reducing the problem of transportation difficulties caused by excessively loose debris; on the other hand, it compresses into regular blocks, which facilitates subsequent processing of aluminum alloy blocks.

[0028] like Figures 4 to 5 As shown, a control unit 5 is installed on the inner wall of the compression chamber 4; a heating wire 51 is fixedly connected to the side wall of the hydraulic cylinder 41; when the compression plate 43 compresses the debris entering the compression chamber 4, the temperature can be adjusted by remotely controlling the control unit 5, thereby operating the heating wire 51 to heat the compression plate 43. At a specific temperature, the aluminum alloy can be better bonded without the need for additional adhesive. Through the setting of the control unit 5 and the heating wire 51, the compression plate 43 can be heated, and at a specific temperature, the aluminum alloy can be better bonded without the need for additional adhesive, reducing the loosening problem caused by inadequate debris compression; at the same time, the setting of the control unit 5 allows for remote control of the temperature of the heating wire 51, reducing the problem of malfunctions in debris compression caused by excessively low or high temperatures.

[0029] like Figures 4 to 5 As shown, a first rubber strip 6 is fixedly connected to the side wall of the compression plate 43; a second rubber strip 61 is fixedly connected to the other side wall of the compression plate 43; the first rubber strip 6 and the second rubber strip 61 are symmetrically arranged; when debris enters the compression chamber 4 for compression, the first rubber strip 6 and the second rubber strip 61 will scrape off the debris adhering to the inner wall of the compression chamber 4 as the compression plate 43 moves; through the arrangement of the first rubber strip 6 and the second rubber strip 61, the debris adhering to the inner wall of the compression chamber 4 can be scraped off as the compression plate 43 moves, reducing the waste caused by debris residue; at the same time, it also reduces the mechanical blockage caused by the accumulation of debris residue.

[0030] Working principle: During operation, the negative pressure suction nozzle 11 is opened and positioned at the aluminum alloy machining tool to adsorb and recover aluminum alloy debris into the filter bucket 1. Once inside the filter bucket 1, the filter screen 12 performs preliminary filtration, removing some large impurities. After the debris enters the centrifuge bucket 14, the rotary motor 13 is turned on, causing the centrifuge bucket 14 to rotate. Utilizing the density difference between aluminum and impurities, cutting fluid residue and light contaminants are separated at a speed of 1200-1500 rpm. Finally, the debris enters the next process through the connecting pipe 15. When the debris passes through the filter screen 12 and enters the centrifuge bucket 14 for centrifugal separation, the magnet 2 adsorbs magnetic impurities, such as iron filings, reducing their contamination in the aluminum alloy debris. During operation, the air inlet pipe 31 is connected to the air pump, allowing air to enter the inflation chamber 3 through the air inlet pipe 31 and then enter the filter bucket 1 through the exhaust port 32. This blows away non-magnetic debris adhering to the magnet 2 inside the centrifuge bucket 14, reducing its adhesion. The case is connected to magnet 2; on the other hand, the cutting fluid entering the filter barrel 1 can be dried to reduce the fusion and clumping of it with the chips; in order to prevent the air pressure inside the filter barrel 1 from being too high, the airflow can be discharged through the exhaust pipe 33; when the chips enter the compression chamber 4 after being filtered, the hydraulic cylinder 41 is opened to drive the telescopic rod 42 to push the compression plate 43 to compress the aluminum alloy chips entering the compression chamber 4, compressing the loose chips into high-density blocks, which is convenient for transportation and subsequent processing; when the compression plate 43 compresses the chips entering the compression chamber 4, the temperature can be adjusted by the remote control control unit 5 to operate the heating wire 51 to heat the compression plate 43, which can better promote the adhesion of aluminum alloy at a specific temperature without the need to add additional adhesive; when the chips enter the compression chamber 4 for compression, the first rubber strip 6 and the second rubber strip 61 will scrape off the chips adhering to the inner wall of the compression chamber 4 as the compression plate 43 moves.
