Description

Technical Field

[0001] The utility model belongs to the technical field of recycled aluminum production, and particularly relates to a pretreatment device for recycled aluminum raw materials. Background Art

[0002] Recycled aluminum is aluminum alloy or aluminum metal obtained by remelting and refining waste aluminum, waste aluminum alloy materials or aluminum-containing scraps. It is an important source of metallic aluminum, and recycled aluminum mainly appears in the form of aluminum alloy.

[0003] Before melting and refining recycled aluminum, processes such as degreasing and cleaning of waste aluminum are required to ensure that there are no other impurities in the waste aluminum that affect the purity after melting. For waste materials with thin aluminum sheets like beverage cans, the crushing rollers are often stuck by the aluminum strips after crushing, resulting in the inability of the crushing rollers to work. Cleaning the stuck aluminum strips requires removing the crushing rollers, and currently, the removal of the crushing rollers is very troublesome, extremely affecting work efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a pretreatment device for recycled aluminum raw materials.

[0005] To achieve the above object, the utility model provides a pretreatment device for recycled aluminum raw materials, including a feed inlet. A material pipe is fixedly installed at the bottom end of the feed inlet. Driving mechanisms are fixedly installed on two sides of the material pipe. A crushing mechanism is fixedly installed at the output end of the driving mechanism. A connecting mechanism is arranged at the connection between the driving mechanism and the crushing mechanism. The connecting mechanism includes two drive shafts fixedly connected to the output ends of the two driving mechanisms. A front roller is slidably connected inside one of the drive shafts. A chute and a locking groove are arranged on the surface of the drive shaft. An elastic member is arranged inside the drive shaft. A pressing plate is fixedly connected to the end face of the elastic member. A locking block is fixedly connected to the outer surface of the front roller, and the locking block is engaged with the locking groove.

[0006] In the above technical solution, further, a rear roller is slidably connected inside the other drive shaft, and the internal structures of the rear roller and the drive shaft are exactly the same as those of the front roller and the drive shaft.

[0007] In the above technical solution, further, crushing teeth are arranged on the outer surfaces of the front roller and the rear roller. The crushing teeth on the surfaces of the front roller and the rear roller are arranged in an alternating manner. Two tooth plates are fixedly connected to the inner wall of the material pipe, and the two tooth plates are respectively engaged with the front roller and the rear roller.

[0008] In the above technical solution, further, a cleaning mechanism is provided at the bottom end of the material pipe. The cleaning mechanism includes a cleaning box fixedly connected to the bottom end of the material pipe. A water outlet is provided at the bottom end of one side of the cleaning box, and a water pump is provided at the top end of the cleaning box.

[0009] In the above technical solution, further, a stirring mechanism is provided inside the cleaning box. The stirring mechanism includes a driving motor fixedly installed at one end of the cleaning box. The output end of the driving motor is fixedly connected to a stirring rod, and the stirring rod is located inside the cleaning box.

[0010] In the above technical solution, further, the sliding groove is connected to the locking groove and is in a "J" shape. The locking block must pass through the sliding groove to cooperate with the locking groove. When the locking block cooperates with the locking groove, the end face of the front roller or the rear roller contacts the pressing plate.

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] 1. Through the connecting mechanism, the roller can be quickly removed from the material pipe. When an aluminum strip jams the roller and makes it unable to work, the roller can be removed by using the quick-disassembly and quick-assembly connecting mechanism, so that the jammed roller can continue to work. The quick-disassembly and quick-assembly method can greatly reduce the impact on work efficiency.

[0013] 2. Through the crushing mechanism, the aluminum cans can be shredded into aluminum strips or aluminum sheets, which is convenient for cleaning, preventing impurities in the aluminum cans from affecting the purity after melting. It not only improves the quality of recycled aluminum, but also reduces the energy consumption during the smelting process, reduces environmental pollution, and at the same time optimizes the production cost of recycled aluminum.

[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0020] - Figures 1 - 4 A pre-treatment device for recycled aluminum raw materials shown in the figure includes a feed inlet 1. A material pipe 2 is fixedly installed at the bottom end of the feed inlet 1. Driving mechanisms 3 are fixedly installed on two sides of the material pipe 2. A crushing mechanism is fixedly installed at the output end of the driving mechanism 3. A connecting mechanism is provided at the connection between the driving mechanism 3 and the crushing mechanism. The connecting mechanism includes two driving shafts 4 fixedly connected to the output ends of the two driving mechanisms 3. A front roller 5 is slidably connected inside one of the driving shafts 4. A chute 9 and a lock groove 10 are provided on the surface of the driving shaft 4. An elastic member 11 is provided inside the driving shaft 4. A pressing plate 12 is fixedly connected to the end face of the elastic member 11. A lock block 13 is fixedly connected to the outer surface of the front roller 5. The lock block 13 is engaged with the lock groove 10. The front roller 5 or the rear roller 6 can be quickly removed through the connecting mechanism. When an aluminum strip gets stuck in the front roller 5 or the rear roller 6, it can be quickly removed and the stuck aluminum strip can be processed, thereby saving the cleaning time and improving the work efficiency.

[0021] A rear roller 6 is slidably connected inside the other driving shaft 4. The internal structures of the rear roller 6 and the driving shaft 4 are exactly the same as the internal structures of the front roller 5 and the driving shaft 4. By using the connecting mechanism, when the roller is connected to the shaft, the driving mechanism 3 can drive the roller to rotate, thereby driving the roller to rotate to crush the aluminum can.

[0022] Crushing teeth 7 are provided on the outer surfaces of the front roller 5 and the rear roller 6. The crushing teeth 7 on the surfaces of the front roller 5 and the rear roller 6 are arranged in a staggered state. Two tooth plates 8 are fixedly connected to the inner wall of the material pipe 2. The two tooth plates 8 are respectively engaged with the front roller 5 and the rear roller 6. The crushing mechanism can crush the aluminum can into a state of aluminum strips or aluminum flakes. The aluminum strips or aluminum flakes can be more conveniently cleaned, avoiding the phenomenon that the inside of the aluminum can cannot be cleaned thoroughly.

[0023] A cleaning mechanism is provided at the bottom end of the material pipe 2. The cleaning mechanism includes a cleaning box 14 fixedly connected to the bottom end of the material pipe 2. At the bottom end on one side of the cleaning box 14, there is a water outlet 17, and the water outlet 17 is connected to a water purification system to recycle the cleaned water and save water resources. At the top end of the cleaning box 14, there is a water pump 18, and the water pump 18 is connected to a water storage tank to facilitate replenishing water inside the cleaning box 14.

[0024] A stirring mechanism is provided inside the cleaning box 14. The stirring mechanism includes a driving motor 15 fixedly installed at one end of the cleaning box 14. The output end of the driving motor 15 is fixedly connected to a stirring rod 16. The stirring rod 16 is located inside the cleaning box 14. The stirring rod 16 can stir the water flow and aluminum sheets, causing the water flow to impact the aluminum sheets and ensuring the cleaning effect of the aluminum sheets.

[0025] The sliding groove 9 is connected to the locking groove 10 and is in a "J" shape. The locking block 13 must pass through the sliding groove 9 to cooperate with the locking groove 10. When the locking block 13 cooperates with the locking groove 10, the end face of the front roller 5 or the rear roller 6 contacts the pressing plate 12. When the driving shaft 4 and the roller are in a connected state, the pressing plate 12 will use the elastic force of the elastic member 11 to push the roller outwards, thereby making the connection between the driving shaft 4 and the roller tighter and preventing the roller from falling off during operation.

[0026] Working principle: First, waste aluminum in the form of containers such as aluminum cans is put in from the feeding port 1. The aluminum cans will first fall above the crushing mechanism. Passing through here can tear the aluminum cans into aluminum strips or aluminum sheets to facilitate their cleaning, ensuring that there are no impurities in the waste aluminum and guaranteeing the purity after melting. The torn aluminum sheets will fall into the cleaning box 14 through the material pipe 2 and then be stirred by the continuously rotating stirring rod 16. After being cleaned, the aluminum sheets can be taken out and melted and refined; when the crushed aluminum strip jams the roller and cannot be directly taken out, the roller needs to be removed. During disassembly, first, the roller is pushed towards the driving mechanism 3. Under the action of the elastic member 11, it is relatively difficult to push. But when it cannot be pushed, it means that the locking block 13 and the locking groove 10 are still out of cooperation. At this time, the roller needs to be rotated to make the locking block 13 located in the sliding groove 9. Finally, the roller can be removed to clean the jammed aluminum strip. When installing the roller, it needs to be first squeezed and then rotated, which is the opposite of the disassembly steps. The disassembly method is relatively simple and fast, greatly reducing the impact on work efficiency.
