Description

Technical Field

[0001] This utility model relates to the field of waste aluminum recycling technology, and in particular to an impurity cleaning device for waste aluminum metal recycling. Background Technology

[0002] With the rapid development of modern industry, aluminum products are widely used in various fields, such as construction, automobile manufacturing, and electronic equipment. However, the amount of waste generated during the production process or reaching the end of the service life of aluminum products is also constantly increasing. Waste aluminum recycling not only promotes resource recycling and reduces dependence on primary aluminum ore resources, but also reduces energy consumption and environmental pollution during aluminum production. However, waste aluminum often contains various impurities during recycling, such as iron filings, dirt, and dust. These impurities can seriously affect the quality of recycled waste aluminum and its subsequent processing performance. Therefore, a highly efficient impurity removal device for waste aluminum metal recycling is needed.

[0003] In the field of waste aluminum cleaning, common cleaning methods are relatively simple. One method is simply washing the surface of the waste aluminum with water to remove dust, dirt, and other impurities. This method is only effective against some surface contaminants and is ineffective at removing other impurities inside the waste aluminum or those that are tightly attached. Another method is to use a vibrating screen to sieve small particles of impurities in the waste aluminum. However, this method has significant limitations; it cannot effectively remove metal impurities such as iron blocks contained in the waste aluminum during the sieving process. Because these simple cleaning methods all have defects, the quality of the recycled waste aluminum is greatly reduced, which in turn adversely affects subsequent processing of the waste aluminum, reducing product performance and increasing processing costs and difficulties.

[0004] Therefore, it is necessary to provide an impurity cleaning device for waste aluminum metal recycling to solve the above-mentioned technical problems. Utility Model Content

[0010] Preferably, a drive shaft is rotatably mounted at both ends of the bracket, and the two drive shafts are connected by a conveyor belt. A conveyor motor is mounted on one side of the bracket, and the output shaft of the conveyor motor is fixedly connected to one of the drive shafts.

[0011] Preferably, protective plates are provided on the supports located on both sides of the conveyor belt, a magnetic belt for magnetically attracting iron filings is connected to the outer surface of the conveyor belt, a connecting frame is fixedly connected to the lower surface of the support, a shovel plate for cleaning iron filings and impurities on the magnetic belt is inclinedly connected to one side of the connecting frame, and a slag collection box for collecting iron filings and impurities is provided below the shovel plate.

[0012] Preferably, the vibration mechanism includes three rotating rods, which are evenly distributed within the conveyor belt. Both ends of each rotating rod are rotatably connected to a support. Each rotating rod is fitted with an eccentric roller, with the middle eccentric roller facing downwards and the two side eccentric rollers facing upwards.

[0013] Preferably, each of the rotating rods is fixedly connected to a sprocket at both ends, and the three sprockets on the same side are connected by chain drive. A vibration motor is provided on one side of the bracket, and the output shaft of the vibration motor is fixedly connected to one of the rotating rods.

[0017] Compared with related technologies, the impurity cleaning device for waste aluminum metal recycling provided by this utility model has the following beneficial effects:

[0018] 1. By installing a magnetic belt on the conveyor belt, iron filings and impurities in the waste aluminum can be effectively adsorbed. Combined with a shovel and slag collection box, this facilitates the collection and cleaning of iron filings, significantly improving the removal efficiency, ensuring the purity of the recycled waste aluminum, and benefiting subsequent processing. The vibration mechanism creates a wave-like vibration effect on the conveyor belt, effectively preventing the accumulation of waste aluminum on the conveyor belt and better adsorbing iron filings and impurities. This improves the comprehensiveness and thoroughness of impurity cleaning, reducing the difficulty and workload of subsequent iron filings removal. The first and second water tanks of the cleaning mechanism, along with a bidirectional water pump and material guide channel, achieve multi-stage cleaning of the waste aluminum, enabling more thorough removal of impurities from the surface of the waste aluminum.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figures 1 to 4 A device for cleaning impurities in waste aluminum metal recycling, comprising:

[0026] The conveying mechanism 2 for conveying waste aluminum is provided with a hopper 1. The conveying mechanism 2 includes a conveyor belt 202 and a support 201. An operation panel 4 is installed on one side of the support 201.

[0027] Vibration mechanism 5 is rotatably mounted on bracket 201 and located inside conveyor belt 202;

[0028] The cleaning mechanism 6 is located at one end of the conveying mechanism 2, and the cleaning mechanism 6 and the discharge hopper 1 are located at both ends of the conveying mechanism 2, respectively.

[0029] refer to Figure 1 , Figure 2 As shown, both ends of the bracket 201 are rotatably mounted with drive shafts, which are connected by a conveyor belt 202. A conveyor motor 203 is mounted on one side of the bracket 201, and the output shaft of the conveyor motor 203 is fixedly connected to one of the drive shafts. Protective plates 204 are provided on the brackets 201 located on both sides of the conveyor belt 202. A magnetic belt 205 for magnetically attracting iron filings is connected to the outer surface of the conveyor belt 202. A connecting frame 206 is fixedly connected to the lower surface of the bracket 201. A shovel plate 207 for cleaning iron filings and impurities on the magnetic belt 205 is inclinedly connected to one side of the connecting frame 206. A slag collection box 3 for collecting iron filings and impurities is provided below the shovel plate 207.

[0030] In practice, in some construction waste aluminum recycling processes, waste aluminum may be mixed with construction metal scrap such as iron blocks, iron filings, and soil. During cleaning, these different types of impurities can be separated from the waste aluminum. First, the waste aluminum to be cleaned is poured into the conveying mechanism 2 through the hopper 1. By setting a magnetic suction belt 205 on the conveyor belt 202, iron filings impurities in the waste aluminum can be effectively adsorbed. In conjunction with the shovel plate 207 and the slag collection box 3, the iron filings can be easily collected and cleaned, greatly improving the removal efficiency of iron filings impurities, ensuring the purity of the recycled waste aluminum, and facilitating subsequent processing.

[0031] refer to Figure 1 , Figure 2 , Figure 3 As shown, the vibration mechanism 5 includes three rotating rods 501, which are evenly distributed within the conveyor belt 202. Both ends of each rotating rod 501 are rotatably connected to the support 201. Each rotating rod 501 is fitted with an eccentric roller 502, with the middle eccentric roller 502 facing downwards and the two side eccentric rollers 502 facing upwards. Both ends of each rotating rod 501 are fixedly connected to a sprocket 503. The three sprockets 503 on the same side are connected by a chain 504. A vibration motor 505 is provided on one side of the support 201, and the output shaft of the vibration motor 505 is fixedly connected to one of the rotating rods 501.

[0032] In practice, the vibration motor 505 is started to drive the connected rotating rod 501 to rotate. Through the transmission of the sprocket 503 and the chain 504, the three rotating rods 501 rotate synchronously. The eccentric rollers 502 on the rotating rods 501 rotate synchronously. Since the middle eccentric roller 502 faces downward and the two side eccentric rollers 502 face upward, the conveyor belt 202 generates a wave-like vibration. Under the action of vibration, the waste aluminum accumulated on the conveyor belt 202 is spread flat on the conveyor belt 202, which helps the magnetic belt 205 to effectively attract iron filings. When the waste aluminum is transported to the cleaning mechanism 6, it falls into the receiving frame 608. The iron filings attracted by the magnetic belt 205 continue to move with the magnetic belt 205 under the action of the magnetic attraction force. Finally, under the action of the shovel plate 207, they are scraped into the slag collection box 3. The protective plate 204 is set to prevent the waste aluminum from falling during the transportation process.

[0033] refer to Figure 1 , Figure 4 As shown, the cleaning mechanism 6 includes a first water tank 601 and a second water tank 602. The first water tank 601 and the second water tank 602 are sequentially arranged at one end of the conveying mechanism 2. A receiving frame 608 for collecting waste aluminum is placed inside the first water tank 601. The receiving frame 608 has drainage holes. The upper middle ends of the first water tank 601 and the second water tank 602 are connected by a guide channel 603. A bidirectional water pump 604 is provided between the first water tank 601 and the second water tank 602 located below the guide channel 603. A forward and reverse motor 605 for driving the bidirectional water pump 604 is provided on one side. Both ends of the bidirectional water pump 604 are connected to water pipes 606. The two water pipes 606 extend into the first water tank 601 and the second water tank 602 respectively. A filter head 607 is connected to one end of each water pipe 606.

[0034] In practice, the scrap aluminum, after being treated by vibration and magnetic attraction, is transported to the cleaning mechanism 6. It first enters the first water tank 601, where the receiving frame 608 collects the scrap aluminum. Water performs a preliminary cleaning of the scrap aluminum, removing residual dust and other impurities. The wastewater flows back to the first water tank 601 through the drain hole. Impurities such as plastic mixed in with the scrap aluminum float on the surface due to buoyancy. When the water level exceeds a certain height, these plastic impurities enter the second water tank 602 through the guide channel 603. The forward and reverse motor 605 drives the bidirectional water pump 604 to operate, pumping water from the first water tank 601 to the second water tank 602 or vice versa through the water pipe 606. Under the impact and movement of the water flow, the scrap aluminum is further cleaned, removing residual impurities from its surface. The cleaned scrap aluminum remains in the receiving frame 608, completing the cleaning and draining process for subsequent recycling.

[0035] The working principle of the impurity cleaning device for waste aluminum metal recycling provided by this utility model is as follows:

[0036] First, the waste aluminum to be cleaned is poured into the conveying mechanism 2 through the hopper 1. Driven by the vibration motor 505, the rotating rod 501 connected to it rotates. Through the transmission of the sprocket 503 and the chain 504, the conveyor belt 202 generates a wave-like vibration, thereby spreading the waste aluminum accumulated on the conveyor belt 202. As the conveyor belt 202 continues to run, the waste aluminum after vibration and magnetic attraction is transported to the first water tank 601. Meanwhile, the iron filings adsorbed on the magnetic belt 205 continue to move with the conveyor belt 202. When the iron filings and impurities pass through the shovel plate 207, they are scraped off by the shovel plate 207 and fall into the slag collection box 3 for collection.

[0037] The receiving frame 608 collects scrap aluminum. Water performs a preliminary cleaning of the scrap aluminum to remove residual dust and other impurities. The wastewater after cleaning flows back to the first water tank 601 through the drain hole. Meanwhile, impurities such as plastic mixed in with the scrap aluminum float on the water surface due to buoyancy. When the water level exceeds a certain height, these plastic impurities enter the second water tank 602 through the guide channel 603. The forward and reverse motor 605 drives the bidirectional water pump 604 to operate, pumping water from the first water tank 601 to the second water tank 602 or vice versa through the water pipe 606. Under the impact and driving force of the water flow, the scrap aluminum is further cleaned, removing the impurities remaining on its surface. The cleaned scrap aluminum remains in the receiving frame 608, completing the cleaning and draining process, which is convenient for subsequent recycling.
