Description

Technical Field

[0001] This utility model relates to the field of particle screening technology, and in particular to a copper-aluminum particle screening device. Background Technology

[0002] In fields such as resource recycling, non-ferrous metal processing, and electronic waste treatment, copper and aluminum, as two widely used and valuable non-ferrous metals, often exist in mixed particulate form. Achieving efficient separation and purification of copper and aluminum particles is a key step in improving resource utilization, reducing raw material costs, and minimizing environmental pollution, and screening serves as one of the pretreatment or core separation methods.

[0003] A typical copper and aluminum particle screening device consists of a feeding mechanism, a screening mechanism, and a discharging mechanism. The feeding mechanism uses a belt conveyor to transport the copper and aluminum particles to be screened to the screening mechanism, providing a basic guarantee for subsequent screening. The screening mechanism uses a vibrating screen to screen the copper and aluminum particles into different finenesses. The discharging mechanism collects the screened copper and aluminum particles separately through a grading hopper.

[0004] In existing technologies, due to the differences in density and shape between copper and aluminum particles, copper and aluminum particles of different sizes are easily mixed during vibrating screening, resulting in low purity of the two metal particles after screening. When the screened particles enter the hopper, they are prone to blockage due to accumulation, leading to poor discharge. Furthermore, when the screening mechanism needs to be changed to screens with different apertures according to different particle size requirements, a large number of connecting parts need to be disassembled, which is cumbersome and time-consuming. This greatly reduces the flexibility and applicability of the device, fails to meet diverse production and processing scenarios, is not convenient to meet people's usage needs, and has low practicality.

[0008] The buffer mechanism includes two movable shafts. The adjacent sides of the movable shafts are fixedly connected to the front side of the vibrating frame. A limit frame is fixedly connected to the top front side of the support frame. A support spring is sleeved on the outside of the movable shaft. A stop plate is slidably connected to the outside of the movable shaft. A support rod is fixedly connected to the bottom of the vibrating frame. Movable rods are rotatably connected to both sides of the support rod. A bottom frame is slidably connected to the outside of each movable rod. A buffer spring is sleeved inside each bottom frame.

[0009] The feeding mechanism includes a feeding frame, the bottom of which is fixedly connected to the top of the top frame. A middle partition is fixedly connected to the inner side of the top of the feeding frame. A baffle plate is fixedly connected to the rear inner side of the feeding frame. An opening and closing plate is slidably connected to the front inner side of the feeding frame. A drive motor is fixedly connected to the outside of the feeding frame. A conveyor belt is installed inside the feeding frame. Concave wheels are fixedly connected to both ends of the conveyor belt. A belt is sleeved on the outside of the concave wheels.

[0010] The output end of the drive motor is fixedly connected to the outside of the concave wheel, the bottom of the baffle plate is installed on the top rear side of the conveyor belt, and the bottom of the opening and closing plate is installed on the top front side of the conveyor belt.

[0011] The top inner side of the limiting frame is rotatably connected to the outside of the movable shaft, one end of the support spring is fixedly connected to the outside of the abutment, the other end of the support spring is fixedly connected to the inner side of the limiting frame, the bottom of the bottom frame is fixedly connected to the top of the support frame, and the inside of the buffer spring is sleeved on the outside of the movable rod.

[0012] The drive assembly includes a rotary motor, which is externally fixedly connected to the top of the top frame, and an eccentric rod is fixedly connected to the output end of the rotary motor.

[0013] The eccentric rod is externally slidably connected to the outer rear side of the vibration frame, and the outer rear side of the vibration frame is engaged with the adjacent side of the top frame.

[0014] The mounting block is externally threaded to the outside of the side outlet, and the outer two sides of the screen are snapped into the inner two sides of the vibrating frame.

[0015] This utility model relates to a copper-aluminum particle screening device.

[0016] 1. In this utility model, the reciprocating vibration of the vibrating frame drives the internal particles to move. At the same time, the partition plate divides the inside of the vibrating frame into sections. Under the action of vibration, the particles are screened through the screen. Fine particles that meet the aperture size move to the side outlet, and the smallest particles move to the bottom outlet. The slope guides the particles to slide to the corresponding side outlet. The mounting block ensures the stability of the side outlet, so as to accurately separate particles of different sizes, avoid particle mixing and accumulation, and ensure that the material after screening is discharged in an orderly manner. By removing the bolts between the mounting block and the side outlet, the screen can be slid out from the partition plate and the vibrating frame after the fixation is released.

[0017] 2. In this utility model, with the cooperation of the front limiting frame at the top of the support frame, the front side of the vibrating frame is connected to the limiting frame through a movable shaft. The support spring outside the movable shaft absorbs the longitudinal impact force of the front side of the vibrating frame through elastic deformation. The abutment plate evenly disperses the spring force to prevent the vibration from being transmitted to the support frame and causing the equipment to shake. With the cooperation of the support rod at the bottom of the vibrating frame, the support rod drives the movable rods on both sides to slide in the bottom frame. The buffer spring in the bottom frame absorbs the sliding impact force of the movable rods through compression and reset, preventing the vibration at the bottom of the vibrating frame from being unbuffered and the components from being easily overloaded and damaged. This solves the problem that during the screening process of the copper and aluminum particle screening device, the impact force generated by the vibration of the vibrating frame is easily transmitted to the support frame, causing the entire equipment to shake, and the lack of effective buffer at the bottom of the vibrating frame easily causes the components to be overloaded and damaged.

[0018] 3. In this utility model, the internal space of the feeding frame is divided by a partition plate to form two independent chambers to hold copper particles and aluminum particles respectively, avoiding pre-mixing of the two types of particles before feeding. At the same time, the inclined plate guides the falling particles in the chamber to gather in the middle of the conveyor belt, preventing the particles from falling from both sides of the conveyor belt. The output end of the drive motor drives the concave wheel to rotate, and the concave wheel drives the concave wheels at both ends of the conveyor belt to rotate synchronously with the help of the external belt, thereby driving the conveyor belt to move at a uniform speed. At the same time, the size of the feeding opening of the feeding frame is adjusted by the sliding opening and closing plate to control the falling speed of the particles, thereby realizing the separate storage of copper and aluminum particles and avoiding the effect of material mixing, falling or unbalanced feeding on the screening quality and efficiency.

[0025] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0026] Please see Figures 1 to 3 This utility model provides a technical solution: a copper-aluminum particle screening device, including a vibrating frame 1 and a support frame 2. The device achieves dynamic screening of particles through the vibrating frame 1, while the support frame 2 provides stable support for the entire device, avoiding equipment shaking during screening and affecting separation accuracy. Two top frames 5 are fixedly connected to the top rear side of the support frame 2. The two top frames 5 are symmetrically distributed and can evenly bear the weight of the feeding mechanism 6. At the same time, they provide a limit for the rear side of the vibrating frame 1 to prevent lateral displacement during vibration. The feeding mechanism 6 is provided on the top of the top frame 5. The screening mechanism 3 is provided inside the vibrating frame 1, and the buffer mechanism 4 is provided outside the vibrating frame 1.

[0027] The screening mechanism 3 includes a partition plate 31, which divides the internal space of the vibrating frame 1 into sections to prevent copper and aluminum particles from mixing during screening. The partition plate 31 is externally fixedly connected to the top inner side of the vibrating frame 1 to ensure its stability under vibration and prevent positional displacement due to vibration. A ramp 32 is fixedly connected to the top outer side of the partition plate 31, which guides the screened particles to slide smoothly to the side outlet 34 and bottom outlet 36, preventing particle accumulation. A screen 33 is snapped into the interior of the partition plate 31. The snap-fit ​​structure facilitates the disassembly and replacement of the screen 33. Different aperture screens 33 can be selected according to actual screening requirements. Side outlets 34 are fixedly connected to both external sides, allowing fine particles that fit the mesh size of the screen 33 to be quickly discharged through the side outlets 34. Mounting blocks 35 are fixedly connected to both external sides of the vibrating frame 1, providing fixed support points for the side outlets 34 and ensuring a tight connection between the side outlets 34 and the vibrating frame 1. Bottom outlets 36 are fixedly connected to the front external side of the vibrating frame 1, used for discharging the smallest particles. A drive assembly 37 is installed on the top of the top frame 5. The external threads of the mounting blocks 35 are connected to the outside of the side outlets 34, facilitating the installation and maintenance of the side outlets 34. The external sides of the screen 33 are snapped into the internal sides of the vibrating frame 1, allowing for easy disassembly and replacement of the snap-fit ​​structure.

[0028] The drive assembly 37 includes a rotary motor 371, which serves as the power core of the drive assembly 37. The rotary motor 371 is externally fixedly connected to the top of the top frame 5, which provides a stable mounting base for the rotary motor 371 and prevents displacement due to vibration during motor operation. An eccentric rod 372 is fixedly connected to the output end of the rotary motor 371. The eccentric rod 372 generates centrifugal force through rotation, converting the rotational motion of the rotary motor 371 into the reciprocating vibration of the vibration frame 1. The eccentric rod 372 is externally slidably connected to the rear side of the vibration frame 1. The sliding connection allows the eccentric rod 372 to have a certain margin when driving the vibration frame 1 to vibrate, preventing jamming between components. The rear side of the vibration frame 1 is snapped onto the adjacent side of the top frame 5. The snapping structure limits the rear side of the vibration frame 1, ensuring that the vibration frame 1 vibrates only in a preset direction.

[0029] like Figures 1 to 3As shown, the buffer mechanism 4 includes two movable shafts 41, which are symmetrically distributed on the front side of the vibration frame 1 to balance the force on the front side of the vibration frame 1. The adjacent sides of the movable shafts 41 are fixedly connected to the outer front side of the vibration frame 1. A limit frame 42 is fixedly connected to the top front side of the support frame 2. The limit frame 42 provides movable support for the movable shafts 41 and restricts their movement. A support spring 43 is sleeved on the outside of the movable shafts 41. The support spring 43 can absorb the longitudinal impact force on the front side of the vibration frame 1 through its own elastic deformation, reducing the vibration transmission to the outside. Support frame 2, externally connected to movable shaft 41 is a sliding abutment 44. The abutment 44 can evenly distribute the elastic force of support spring 43, preventing excessive local stress on the spring and thus preventing damage. Support rod 45 is fixedly connected to the bottom of vibration frame 1. Support rod 45 transmits the weight of the bottom of vibration frame 1 to movable rod 46, and at the same time provides a fulcrum for rotation of movable rod 46. Movable rods 46 are rotatably connected to both sides of the support rod 45. Movable rods 46 can adapt to the up and down vibration of vibration frame 1 by rotation. Bottom frame 47 is slidably connected to the outside of movable rod 46. 47 provides sliding space for the movable rod 46 while limiting its range of motion. Each frame 47 is internally fitted with a buffer spring 48. The buffer spring 48 absorbs the impact force generated when the movable rod 46 slides through compression and reset, further enhancing the buffering effect. The top inner side of the limiting bracket 42 is rotatably connected to the outside of the movable shaft 41. This rotatable connection reduces the frictional resistance between the movable shaft 41 and the limiting bracket 42. One outer end of the support spring 43 is fixedly connected to the outside of the abutment plate 44, allowing the elastic force of the support spring 43 to act precisely. The vibration is transmitted to the abutment plate 44 and then to the movable shaft 41. The other end of the support spring 43 is fixedly connected to the outer inner side of the limit frame 42. The limit frame 42 provides fixed support for the support spring 43 to ensure that the spring is stable in position during vibration. The bottom of the bottom frame 47 is fixedly connected to the top of the support frame 2. The support frame 2 provides a stable foundation for the bottom frame 47 to ensure the overall structural stability of the buffer mechanism 4. The inside of the buffer spring 48 is sleeved on the outside of the movable rod 46 to ensure that the buffer spring 48 can extend and retract along the axial direction of the movable rod 46 and avoid lateral displacement of the spring.

[0030] like Figure 1 , Figure 2 and Figure 4As shown, the feeding mechanism 6 includes a feeding frame 61, which can store a certain amount of copper-aluminum mixed particles to achieve intermittent or continuous feeding, meeting the needs of different screening rhythms. The bottom of the feeding frame 61 is fixedly connected to the top of the top frame 5, which provides stable support for the feeding frame 61. A middle partition 62 is fixedly connected to the inner top of the feeding frame 61, dividing the interior of the feeding frame 61 into two independent chambers, which can store copper particles and aluminum particles respectively. A baffle plate 63 is fixedly connected to the rear interior of the feeding frame 61, which guides the particles to gather in the middle of the conveyor belt 68, preventing the particles from falling from both sides of the conveyor belt 68. An opening and closing plate 64 is slidably connected to the front interior of the feeding frame 61. By sliding the opening and closing plate 64, the size of the feeding opening can be adjusted, thereby controlling the feeding speed of the particles and preventing the screen 33 from being blocked due to excessive feeding speed. A drive motor 65 is fixedly connected to the outside of the feeding frame 61. 5 provides power for the movement of the conveyor belt 68, ensuring stable rotation speed. The conveyor belt 68 is installed inside the discharge frame 61. The conveyor belt 68 can evenly transport the particles to the screen 33 of the vibrating frame 1, avoiding particle accumulation. Concave wheels 66 are fixedly connected to both ends of the outer side of the conveyor belt 68. The concave wheels 66, in cooperation with the belt 67, transmit the power of the drive motor 65 to both ends of the conveyor belt 68. The belt 67 is sleeved on the outside of the concave wheels 66, which can ensure that the conveyor belt 68 moves at a uniform speed. The output end of the drive motor 65 is fixedly connected to the outside of the concave wheels 66. The bottom of the baffle plate 63 is installed on the top rear side of the conveyor belt 68, ensuring that the particles falling from the rear side of the discharge frame 61 can be guided by the baffle plate 63 to the middle of the conveyor belt 68. The bottom of the opening and closing plate 64 is installed on the top front side of the conveyor belt 68. The position allows the opening and closing plate 64 to accurately control the amount of particles on the conveyor belt 68, ensuring uniform feeding.

[0031] Working principle: During feeding, copper particles and aluminum particles are first placed into two independent chambers of the feeding frame 61 separated by the partition plate 62. Under their own gravity, the particles move towards the conveyor belt 68. The baffle plate 63 guides the particles to gather in the middle of the conveyor belt 68 to prevent the particles from falling from the sides. The drive motor 65 is started, and its output end drives the concave wheel 66 to rotate. The concave wheel 66 drives the concave wheels 66 at both ends of the conveyor belt 68 to rotate synchronously through the externally sleeved belt 67, thereby making the conveyor belt 68 move at a uniform speed. At the same time, the sliding opening plate 64 adjusts the size of the feeding port to control the feeding speed of the particles and prevent the feeding from being too fast. The conveyor belt 68 evenly transports the particles to the screen 33 inside the vibrating frame 1.

[0032] During screening, the rotating motor 371 installed on the top of the top frame 5 is started. The output end of the rotating motor 371 drives the eccentric rod 372 to rotate. The centrifugal force generated by the rotation of the eccentric rod 372 converts the rotational motion into the reciprocating vibration of the vibrating frame 1. The top frame 5 acts as a limiter on the rear side of the vibrating frame 1, ensuring that the vibrating frame 1 vibrates only in the preset direction. During vibration, the partition plate 31 divides the interior of the vibrating frame 1 into sections to prevent different particles from mixing. Under the action of vibration, the particles are screened through the screen 33. Fine particles that meet the aperture of the screen 33 move towards the side outlet 34, while the smallest particles move towards the bottom outlet 36 on the front side of the vibrating frame 1. The ramp 32 guides the screened particles to slide smoothly to the corresponding outlet, avoiding particle accumulation. The mounting block 35 ensures the stable operation of the side outlet 34. When replacing the screen 33, the bolts between the mounting block 35 and the side outlet 34 are removed, allowing the screen 33 to slide out of the partition plate 31 and the interior of the vibrating frame 1 for cleaning and replacement.

[0033] During buffering, when the vibrating frame 1 vibrates, its front side is connected to the limiting frame 42 on the front top of the support frame 2 via the movable shaft 41. The support spring 43 sleeved outside the movable shaft 41 absorbs the longitudinal impact force on the front side of the vibrating frame 1 through elastic deformation. The abutment plate 44 evenly disperses the elastic force of the support spring 43, reducing the vibration transmitted to the support frame 2. At the same time, the support rod 45 at the bottom of the vibrating frame 1 drives the movable rods 46 on both sides to slide in the bottom frame 47. The buffer spring 48 sleeved inside the bottom frame 47 absorbs the impact force generated by the sliding of the movable rods 46 through compression and reset, further enhancing the buffering effect and ensuring the stable operation of the device.
