Description

Technical Field

[0001] This utility model relates to the technical field of waste aluminum recycling equipment, specifically a waste aluminum recycling and processing device. Background Technology

[0002] With the rapid development of industry and the widespread application of aluminum products in many fields, the amount of aluminum waste generated is increasing day by day. As an important recyclable resource, the efficient recycling and processing of waste aluminum not only helps to save resources and reduce production costs, but also reduces the pressure on the environment, which is in line with the current trend of sustainable development and resource recycling.

[0003] A search revealed a waste aluminum recycling device disclosed in Chinese Patent No. CN220759369U. The device uses a rotating first shaft to drive an eccentric wheel, which intermittently impacts a lifting plate. The lifting plate compresses a telescopic spring. When the eccentric wheel moves away from the lifting plate, the lifting plate returns to its original position under the elastic force of the telescopic spring. The lifting plate drives a magnetic plate to reciprocate through a limiting plate and a connecting plate, facilitating the vibration conveying of iron products that fall onto the magnetic plate.

[0004] However, in the existing technology, a large amount of dust is generated during the crushing and conveying of waste aluminum, which not only pollutes the working environment but may also affect the health of operators. After long-term use, the screening components are prone to clogging due to the adhesion of impurities. The lack of an effective cleaning structure requires frequent shutdowns for manual cleaning, which further affects the continuous operation capability and processing efficiency of the equipment. Therefore, a new solution is needed to solve this problem. Utility Model Content

The guide plate 2 is semi-circular and the fixing frame 3 is circular. The guide plate 2 and the fixing frame 3 are arranged on the same axis.

[0019] See Figure 2 , Figure 4As shown, one end of the guide plate 2 is set inside the fixed frame 3 to ensure that the waste aluminum particles can be smoothly transferred to the filter plate 4 and avoid falling. The filter plate 4 is set on the fixed frame 3. The filter plate 4 is connected to the fixed frame 3 by bolts for easy replacement of filter plates 4 with different apertures according to recycling needs. The filter plate 4 is made of high manganese steel, which has high strength and wear resistance. A rotating component is set between the fixed frame 3 and the outer shell 1. The rotating component includes a fixed plate 5 and a fixed plate 6.

[0020] See Figure 2 , Figure 3 , Figure 4 As shown, fixing plate 5 and fixing plate 6 are respectively set at both ends of fixing frame 3. Fixing plate 5 and fixing plate 6 are fixedly connected to the inner wall of outer shell 1. Fixing plate 5 and fixing plate 6 are rotatably connected to fixing frame 3. Deep groove ball bearings are installed at the rotatable connection between fixing frame 3 and fixing plate 5 and fixing plate 6. The outer ring of the bearing is fixed to the fixing plate, and the inner ring is welded to fixing frame 3 to reduce rotational friction. There are two fixing plates 6. A driven wheel 8 is installed on the fixing frame 3 between the two fixing plates 6.

[0021] In this embodiment, a drive wheel 7 is provided below the driven wheel 8. The drive wheel 7 is rotatably mounted on the fixed plate 5. The power end of the drive wheel 7 is provided with a drive source 9. The drive source 9 is a geared motor. The power is determined according to the weight of the fixed frame 3 and the filter plate 4 and the required speed. Its output shaft is connected to the drive wheel 7 through a coupling. A through hole 14 is provided below the two fixed plates 5. A horizontal plate 15 is provided between the through hole 14 and the drive wheel 7. The horizontal plate 15 is fixedly connected to the two fixed plates 5.

[0022] In this embodiment, a dustproof shell 10 is provided on the outside of the drive source 9. The dustproof shell 10 is installed on the fixed plate 5. In addition to covering the drive source 9, the dustproof shell 10 can have ventilation holes at its bottom and be equipped with a dustproof net to prevent dust from entering the drive source 9 and to ensure the heat dissipation of the motor. A transmission wheel 11 is engaged above the driven wheel 8. The transmission wheel 11 is rotatably installed on the fixed plate 5 through the rotating shaft 12. A brush roller 13 is provided between the rotating shaft 12 and the fixed plate 6. The brush bristles of the brush roller 13 are made of nylon filaments, which are wear-resistant and do not easily scratch the filter plate 4.

[0023] See Figure 2 , Figure 4As shown, one end of the brush roller 13 is fixedly connected to the rotating shaft 12, and the other end of the brush roller 13 is rotatably connected to the fixed plate 6. The rotation direction of the brush roller 13 is opposite to the rotation direction of the fixed frame 3. The cleaning effect is enhanced by reverse friction. The other end of the guide plate 2 is provided with a dust collection component, which includes a dust collection pipe 16. The dust collection pipe 16 is made of PVC hard pipe. The dust inlet end of the dust collection pipe 16 is installed on the outer shell 1. A filter screen is provided on the dust inlet end of the dust collection pipe 16. The filter screen is a metal mesh. The other end of the dust collection pipe 16 is provided with a dust collection box 18, which is installed on the outer shell 1.

[0024] A fan 17 is installed between the dust collection box 18 and the suction pipe 16. The fan 17 is a centrifugal fan. A crushing component is installed above the guide plate 2. The crushing component includes a crushing roller 19. The crushing roller 19 is rotatably mounted on the outer shell 1. There are two crushing rollers 19, which are symmetrically distributed on the left and right sides. The roller surface is evenly covered with serrated protrusions. A feeding port is provided on the outer shell 1 above the crushing roller 19. A flip cover is installed at the feeding port to prevent waste aluminum particles from splashing during crushing. An inspection door is opened on the rear side of the outer shell 1 to facilitate the maintenance and cleaning of the internal components. A stepper motor is installed at the power end of the crushing roller 19. A receiving box 20 is installed below the fixing frame 3. The receiving box 20 is slidably installed with the outer shell 1.

[0025] The implementation principle is as follows: the waste aluminum raw material is put into the shell 1 and first comes into contact with the crushing component. The crushing roller 19 in the crushing component rotates under the drive of the stepper motor to crush the waste aluminum raw material. The crushed waste aluminum particles fall on the inclined semi-circular guide plate 2. With the help of the inclined angle of the guide plate 2, the waste aluminum particles slide along the guide plate 2 and finally enter the inner side of the circular fixing frame 3 set on the same axis as the guide plate 2. When the drive source 9 is started, it drives the drive wheel 7 installed on the fixed plate 5 to rotate. The drive wheel 7 meshes with the driven wheel 8 on the fixed frame 3, thereby driving the fixed frame 3 to rotate on the fixed plate 5 and the fixed plate 6. The filter plate 4 on the fixed frame 3 rotates together with the fixed frame 3 to screen the waste aluminum particles. Particles that meet the requirements roll down the filter plate 4 and the fixed frame 3 into the collection box 20. Smaller particles and dust impurities pass through the filter plate 4. When the collection box 20 collects a certain amount of waste aluminum particles, it can be extracted from the outer shell 1 for further processing. During the rotation of the fixed frame 3, the transmission wheel 11 meshing with the driven wheel 8 drives the brush roller 13 to rotate through the rotating shaft 12. Under the support of the fixed plate 6, the brush roller 13 continuously cleans the rotating filter plate 4 to prevent impurities from adhering and clogging the filter plate 4. At the same time, the dust collection component works, the fan 17 runs to generate suction, and the dust generated during the crushing and conveying of waste aluminum is sucked in through the dust collection pipe 16 installed on the outer casing 1. The filter screen at the dust inlet end of the dust collection pipe 16 prevents larger waste aluminum particles from entering the dust collection pipe 16. The dust is finally collected in the dust collection box 18 installed on the outer casing 1.
