[0002] Aluminum is a metallic element, a silvery-white, lightweight metal with ductility. It is commonly produced in rods, sheets, foils, powders, strips, and wires. In moist air, it forms an oxide film that prevents corrosion. Aluminum powder burns violently when heated in air, emitting a dazzling white flame. Aluminum is the third most abundant metallic element in the Earth's crust, after oxygen and silicon. The development of the three major industries—aviation, construction, and automobiles—demands materials with the unique properties of aluminum and its alloys, which greatly benefits the production and application of this new metal. "Scrap aluminum" is a common term for recycled aluminum.

[0003] In the process of recycling waste aluminum, it is necessary to clean the waste aluminum to remove oil and dirt and maintain its cleanliness. To address this issue, we propose a waste aluminum recycling impurity removal device. Utility Model Content

[0021] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0022] Example: Refer to Figures 1-3 As shown, this embodiment of a waste aluminum recycling impurity removal device includes a processing box 1. A cleaning box 2 is provided at the bottom inner side of the processing box 1. A crushing component is provided at the middle upper part of the cleaning box 2. The crushing component includes two sets of crushing rollers 3. The two sets of crushing rollers 3 are movably installed at the upper inner side of the processing box 1. A flushing nozzle 4 is provided on the back of each set of crushing rollers 3. The crushing rollers 3 can be flushed and cleaned by the flushing nozzle 4 to avoid a large amount of dust and debris adsorbing on the crushing rollers 3, which would affect the performance of the crushing rollers 3.

[0023] The stirring assembly is installed in the middle of the inner side of the cleaning tank 2 and at the bottom of the crushing assembly. The stirring assembly includes a stirring shaft 6, and four sets of stirring blades 7 are installed on the outer wall of the stirring shaft 6. The four sets of stirring blades 7 are arranged in a cross shape. Multiple sets of drainage holes 8 are equally spaced on the inner side of each of the four sets of stirring blades 7, thereby reducing the resistance when the stirring blades 7 rotate and improving the smoothness of the rotation. This allows the stirring blades 7 to smoothly scrape and stir the aluminum fragments, so that the aluminum fragments and the cleaning liquid are fully mixed, thereby improving the cleaning effect of degreasing and removing dirt from the aluminum fragments.

[0024] The drive assembly is installed on the outer right wall of the processing box 1. The drive assembly is used to drive the crushing assembly and the stirring assembly to rotate synchronously. The drive assembly includes a motor 15, which is fixedly installed on the lower right side of the processing box 1. The output end of the motor 15 is connected to the head end of the stirring shaft 6. The head ends of the two sets of crushing rollers 3 are provided with drive gears 14, and the two sets of drive gears 14 are meshed together. The drive gear 14 located on the left side is connected to the output end of the motor 15 through a synchronous pulley and a synchronous belt.

[0025] The drive component is designed to allow the mixing and crushing components to rotate synchronously, creating a linkage that enhances the utilization of driving force and reduces energy waste.

[0026] Two sets of water pipes are installed on the back of the processing tank 1, namely the first water supply pipe 12 and the second water supply pipe 13. The outlet of the first water supply pipe 12 is located on the upper left side of the cleaning tank 2. The outlet of the second water supply pipe 13 is connected to two sets of rinsing nozzles 4 through a delivery hose. Both the first water supply pipe 12 and the second water supply pipe 13 are connected to an external cleaning liquid storage tank and are transported by a water pump. The first water supply pipe 12 is mainly used to inject cleaning liquid into the cleaning tank 2, while the second water supply pipe 13 is used to pressurize the cleaning liquid and transmit it to the rinsing nozzles 4 on both sides, and then spray it out through the rinsing nozzles 4 to clean the crushing roller 3.

[0027] In some examples, a feed hopper 17 is provided at the top center of the processing box 1, and two sets of crushing rollers 3 are located at the bottom center of the feed hopper 17. The feed hopper 17 guides the waste aluminum blocks so that they can fall precisely in front of the two sets of crushing rollers 3 for crushing.

[0028] In some examples, a guide plate 5 is installed in the middle of the inner side of the processing box 1. The guide plate 5 is located in the middle of the bottom end of the two sets of crushing rollers 3. The guide plate 5 guides and separates the broken aluminum blocks, thereby effectively preventing the broken aluminum blocks from falling from above onto the mixing assembly and causing damage to the mixing assembly.

[0029] In some examples, a discharge pipe 10 is provided at the bottom center of the processing tank 1. The discharge pipe 10 is located at the bottom center of the cleaning tank 2, and a flat gate valve 11 is provided at the inlet of the discharge pipe 10. When the flat gate valve 11 is opened, the broken aluminum pieces and cleaning liquid inside the cleaning tank 2 will be discharged outward through the discharge pipe 10.

[0030] In some examples, the cleaning tank 2 is designed as a semi-circular structure, and the end of the stirring blade 7 is provided with an arc-shaped scraper 9. When the stirring blade 7 rotates to the bottom of the cleaning tank 2, the scraper 9 contacts the bottom of the cleaning tank 2, so that the stirring blade 7 can scrape the broken aluminum pieces located at the bottom of the cleaning tank 2, and even rotate with the stirring blade 7, so that the broken aluminum pieces and the cleaning liquid are fully mixed, thereby improving the cleaning effect of degreasing and removing dirt from the broken aluminum pieces.

[0031] In some examples, a protective cover 16 is provided at the middle of the right end of the processing box 1. The protective cover 16 covers the periphery of the drive component and plays a protective role, enhancing the safety of the drive component during use.

[0032] The working principle of this utility model is as follows:

[0033] During use, waste aluminum is first evenly fed into the feed hopper 17. Under the guidance of the feed hopper 17, the waste aluminum falls into the crushing component for crushing. The aluminum fragments crushed by the two sets of crushing rollers 3 fall downwards and are then guided by the guide plate 5 so that they fall from both sides of the guide plate 5 into the washing box 2 below.

[0034] Meanwhile, the operation of the drive component drives the two sets of crushing rollers 3 to rotate simultaneously, which in turn drives the stirring shaft 6 to rotate. When the aluminum fragments fall into the cleaning tank 2, the rotation of the stirring shaft 6 drives the four sets of stirring blades 7 to rotate, thereby stirring the aluminum fragments that fall into the cleaning tank 2. This allows the cleaning fluid to thoroughly clean the aluminum fragments, remove oil stains, and improve the cleanliness of the aluminum fragments, thus facilitating subsequent recycling and processing of the aluminum fragments.

[0035] After the aluminum scraps are cleaned, the flat gate valve 11 is opened and the aluminum scraps and wastewater are discharged through the discharge pipe 10. Then, the aluminum scraps are rinsed and cleaned with clean water, thereby effectively enhancing the recycling and cleaning effect of the aluminum scraps.

[0036] In addition, after the material discharge is completed, the crushing roller 3 can be rinsed by turning on the flushing nozzle 4 on the back of the crushing roller 3 to prevent dust and debris from adhering to the outer surface of the crushing roller 3, which would affect the crushing effect on the aluminum block. At the same time, the crushing roller 3 is cleaned to keep it clean and prepare it for the next crushing operation.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
