Description

Technical Field

[0001] This invention relates to the field of impurity separation technology, specifically to a device for separating metal impurities from shredded pipe waste. Background Technology

[0002] With increasingly stringent environmental protection requirements, the direct disposal of a large number of plastic pipes containing metal reinforcing ribs after they have been used and are no longer usable will result in resource waste and environmental pollution.

[0003] Patent application CN201110326954.8 discloses a sorting and separating device for crushed or fallen polyethylene pipe materials, including a frame and a flowing filter tank. The device is characterized by: a feeding hopper, a primary screen, and a secondary screen arranged sequentially from top to bottom on the frame; the flowing filter tank being located below one outlet of the secondary screen; both the primary and secondary screens being connected to an eccentric shaft connected to a motor; and a magnetic frame installed inside the feeding hopper. This device effectively separates irregularly shaped crushed materials such as iron filings, stones, mud, and straw from regular crushed materials, including iron filings, powder chips, strips, and filaments, thus achieving sorting and recycling. The sorted materials, after drying and remanufacturing, significantly improve phenomena such as bridging, clogging of the feeding port, and unstable wall thickness during extrusion manufacturing, resulting in significant energy savings, reduced production costs, and overall improvement.

[0004] Existing equipment typically employs only a single physical separation method, resulting in poor separation purity of metal impurities and overall processing efficiency. This is detrimental to the stability of subsequent plastic granulation quality and the direct recycling of iron materials. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device for separating metal impurities from shredded pipe waste, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal impurity separation device for shredded pipe waste, comprising a base, a first support column fixedly connected to the bottom of the base, a first guide plate fixedly connected to the top of the base, a through hole opened on the rear side of the first guide plate, a storage frame fixedly connected to the top of the first guide plate, an air supply device fixedly connected to the outer wall of the first support column, and a separation mechanism fixedly connected to the front side of the base.

[0007] The separation mechanism includes:

[0008] The outer casing has a feed inlet on its rear side, and a second guide plate is fixedly connected to the inner side of the feed inlet. The bottom of the second guide plate is arc-shaped. A support plate is fixedly connected to the bottom of the outer casing, and a second support column is fixedly connected to the bottom of the outer casing. A vibration component is movably connected to the inner wall of the outer casing. The rear side of the support plate is the outlet for ferrous materials, and the front side of the support plate is the outlet for non-ferrous materials.

[0009] According to the above technical solution, the inner wall of the base is rotatably connected to a threaded column via a bearing, and the outer wall of the base is fixedly connected to a first motor. The output end of the first motor is fixedly connected to the threaded column, and the outer wall of the threaded column is threadedly connected to a sliding plate. The rotation of the threaded column can drive the sliding plate to move.

[0010] According to the above technical solution, a connecting plate is fixedly connected to the outer wall of the top of the sliding plate, a sliding column is fixedly connected to the outer wall of the connecting plate, the outer wall of the sliding column is movably connected to the through hole, and a push plate is fixedly connected to the end of the sliding column away from the connecting plate. The movement of the sliding plate is used to drive the push plate to move, and the movement of the push plate can push the first guide plate into the inner wall of the separation mechanism.

[0011] According to the above technical solution, the outer wall of the push plate is movably connected to the first guide plate, and a first baffle is fixedly connected to the rear side of the push plate, wherein the first baffle is used to prevent debris from falling into the rear side of the first guide plate.

[0012] According to the above technical solution, an air inlet is fixedly connected to the outer wall of the shell, and the air outlet of the air supply device is fixedly connected to the air inlet. The air supplied by the air supply device is sent into the interior of the shell through the air inlet. By setting a separation mechanism, a high-speed airflow is provided on the iron material outlet side and sent into the interior of the shell through the air inlet to blow away the iron material that still has plastic particles after magnetic separation. This airflow can effectively blow the plastic particles attached to the surface of the iron material back to the non-iron material side, thereby further enhancing the separation purity of non-iron materials and reducing the plastic entrainment rate in the iron material.

[0013] According to the above technical solution, a hollow column is fixedly connected inside the outer shell, a second baffle is fixedly connected to the outer wall of the hollow column, and a third baffle is fixedly connected to the outer wall of the hollow column. The third baffle and the second baffle are used to guide the material. By setting a separation mechanism, the third baffle fixed to the outer wall of the hollow column and the protrusions on the shaking component cooperate with each other to make the broken material undergo multiple collisions during the falling process, thereby effectively reducing its falling speed. This avoids the broken material falling too fast, which would prevent the magnet from being able to fully capture the iron particles in it, and further enhances the adsorption capacity of magnetic separation and the iron recovery rate.

[0014] According to the above technical solution, a rotating roller is installed inside the hollow column. The inner wall of the outer shell is threadedly connected to the rotating roller via a bearing. A magnet is fixedly connected to the outer wall of the rotating roller. A third motor is fixedly connected to the outer wall of the outer shell. The output end of the third motor is fixedly connected to the rotating roller. The third motor is used to drive the rotating roller to rotate. By setting a separation mechanism, the rotating roller drives the magnet to rotate in the opposite direction, so that the ferromagnetic material falling freely downward is attracted by magnetic force and deflected with the direction of rotation, and finally the iron material exits from the outlet on the rear side of the support plate. This design not only effectively avoids the mixing of iron and non-iron materials, but also improves the separation purity and collection efficiency of metal impurities, and enhances the continuity and stability of the separation process.

[0015] According to the above technical solution, a second motor is fixedly connected to the top of the housing, and the output end of the second motor is fixedly connected to the vibration component. The second motor is used to provide a power source for the movement of the vibration component.

[0016] According to the above technical solution, the shaking component includes a rotating column. The inner wall of the outer shell is rotatably connected to the rotating column via a bearing. An eccentric column is fixedly connected to the inner side of the rotating column, and a connecting rod is rotatably connected to the outer wall of the eccentric column via a bearing. A second motor is used to drive the rotating column to rotate. By setting the shaking component, the reciprocating shaking generated by the movable frame and the protruding plate continuously disperses and redistributes the debris under this continuous shaking action, effectively preventing the plastic debris and ferromagnetic particles from adhering to or agglomerating with each other. This further enhances the dispersion of materials in the separation area, providing more ideal loose materials for wind separation and magnetic adsorption, and improving the overall separation efficiency and processing capacity.

[0017] According to the above technical solution, a movable frame is movably connected to the inner wall of the outer shell, a protruding plate is fixedly connected to the side of the movable frame away from the rotating column, a partition is fixedly connected to the inner side of the movable frame, a connecting column is fixedly connected to the outer wall of the partition, and the outer wall of the connecting column is rotatably connected to the connecting rod through a bearing, wherein the rotation of the rotating column drives the protruding plate to move through the connecting rod.

[0018] Compared with the prior art, the present invention provides a device for separating metal impurities from shredded pipe waste, which has the following beneficial effects:

[0019] 1. This invention sets up a separation mechanism that uses a rotating roller to drive a magnet to rotate in the opposite direction, causing the ferromagnetic material that falls freely downwards to be attracted by magnetic force and deflected with the direction of rotation, ultimately causing the iron material to exit from the outlet on the back side of the support plate. This design not only effectively avoids the mixing of iron and non-iron materials, but also improves the separation purity and collection efficiency of metal impurities, and enhances the continuity and stability of the separation process.

[0020] 2. By setting up a separation mechanism, the present invention utilizes the cooperation between the third baffle fixed on the outer wall of the hollow column and the protrusion on the shaking component to cause the crushed material to be subjected to multiple collisions during its fall, thereby effectively reducing its falling speed; and preventing the magnet from being unable to fully capture the iron particles due to the crushed material falling too fast, thus further enhancing the adsorption capacity of magnetic separation and the iron recovery rate.

[0021] 3. The present invention provides a high-speed airflow on the iron material outlet side by setting a separation mechanism, which is sent into the shell through the air inlet to blow away the iron material that still has plastic particles after magnetic separation. This airflow can effectively blow the plastic particles attached to the surface of the iron material back to the non-iron material side, thereby further enhancing the separation purity of non-iron materials and reducing the plastic entrainment rate in the iron material.

[0022] 4. By setting up a shaking component, the present invention utilizes the reciprocating shaking generated by the movable frame and the raised plate. Under this continuous shaking action, the debris is constantly scattered and redistributed, effectively preventing the plastic debris and ferromagnetic particles from adhering to each other or agglomerating. This further enhances the dispersion of materials in the separation area, providing more ideal loose materials for wind separation and magnetic adsorption, and improving the overall separation efficiency and processing capacity.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0037] Example 1: See Figures 1-4The present invention provides a technical solution: a metal impurity separation device for shredded pipe waste, comprising a base 1, a first support column 101 fixedly connected to the bottom of the base 1, a first guide plate 103 fixedly connected to the top of the base 1, a through hole 104 opened on the rear side of the first guide plate 103, a storage frame 1012 fixedly connected to the top of the first guide plate 103, an air supply device 102 fixedly connected to the outer wall of the first support column 101, and a separation mechanism 2 fixedly connected to the front side of the base 1; the inner wall of the base 1 rotates via bearings. A threaded post 106 is connected to the base 1. A first motor 105 is fixedly connected to the outer wall of the base 1. The output end of the first motor 105 is fixedly connected to the threaded post 106. A sliding plate 1010 is threadedly connected to the outer wall of the threaded post 106. The rotation of the threaded post 106 can drive the sliding plate 1010 to move. A connecting plate 109 is fixedly connected to the outer wall of the top of the sliding plate 1010. A sliding post 107 is fixedly connected to the outer wall of the connecting plate 109. The outer wall of the sliding post 107 is movably connected to the through hole 104. The sliding post 107 is far from the... A push plate 108 is fixedly connected to one end of the connecting plate 109. The movement of the sliding plate 1010 drives the push plate 108 to move. The movement of the push plate 108 can push the first guide plate 103 into the inner wall of the separation mechanism 2. The outer wall of the push plate 108 is movably connected to the first guide plate 103. A first baffle 1011 is fixedly connected to the rear side of the push plate 108. The first baffle 1011 is used to prevent shredded material from falling into the rear side of the first guide plate 103. When processing is required, the shredded waste to be processed is placed... The material is placed into the storage box 1012; then the first motor 105 is started, and its output end drives the threaded column 106 to rotate. The rotation of the threaded column 106 drives the sliding plate 1010 to move linearly. The moving sliding plate 1010 drives the push plate 108 through the connecting plate 109 and the sliding column 107, pushing the material on the first guide plate 103 into the separation mechanism 2 for subsequent metal impurity separation; by controlling the forward and reverse rotation of the first motor 105, the reciprocating pushing action of the push plate 108 is realized, thereby sending the waste to be separated into the separation mechanism 2.

[0038] Example 2: Please refer to Figures 5-9Based on Embodiment 1, the present invention provides a technical solution: the separation mechanism 2 includes: a housing 201, an inlet 204 on the rear side of the housing 201, a second guide plate 205 fixedly connected to the inner side of the inlet 204, the bottom of the second guide plate 205 being arc-shaped, a support plate 2012 fixedly connected to the bottom of the housing 201, a second support column 203 fixedly connected to the bottom of the housing 201, and a shaking assembly 21 movably connected to the inner wall of the housing 201. The rear side of the support plate 2012 is the outlet for ferrous materials, and the front side of the support plate 2012 is the outlet for non-ferrous materials. An air inlet 202 is fixedly connected to the outer wall of housing 201. The air outlet of air supply device 102 is fixedly connected to the air inlet 202. Air supplied by air supply device 102 is sent into the interior of housing 201 through air inlet 202. A hollow column 2010 is fixedly connected to the interior of housing 201. A second baffle 2011 and a third baffle 2013 are fixedly connected to the outer wall of hollow column 2010. The third baffle 2013 and the second baffle 2011 are used to guide materials. A rotating roller 208 is provided inside hollow column 2010. The inner wall of housing 201 is open to the air supply. A bearing is threadedly connected to a rotating roller 208. A magnet 209 is fixedly connected to the outer wall of the rotating roller 208. A third motor 207 is fixedly connected to the outer wall of the outer shell 201. The output end of the third motor 207 is fixedly connected to the rotating roller 208. The third motor 207 is used to drive the rotating roller 208 to rotate. A second motor 206 is fixedly connected to the top of the outer shell 201. The output end of the second motor 206 is fixedly connected to the vibration assembly 21. The second motor 206 is used to provide a power source for the movement of the vibration assembly 21. The shredded waste pushed by the pusher plate 108 enters the separator from the first inlet plate 103. The material enters through the inlet 204 on the rear side of the structure 2 and slides down along the second guide plate 205 into the interior of the outer shell 201. During the falling process, the material will come into contact with the shaking component 21 and be scattered. Then the scattered material continues to fall and enters the channel formed by the hollow column 2010, the second baffle 2011 and the third baffle 2013. At this time, the third motor 207 drives the rotating roller 208 and the magnet 209 to rotate in the opposite direction. The magnet 209 generates magnetic attraction to the ferromagnetic impurities in the falling material, so that the iron material is attracted and moves with the rotation direction of the rotating roller 208, so that the iron material is finally discharged from the iron material outlet on the rear side of the support plate 2012. The unadsorbed non-ferrous materials continue to fall and are discharged from the non-ferrous material outlet on the front side of the support plate 2012. During this process, the air force generated by the air supply device 102 is sent into the interior of the outer shell 201 through the air inlet 202. This airflow can form a strong wind on the iron material outlet side, blowing the plastic particles attached to the surface of the iron material back to the non-ferrous material side, further improving the purity of the iron material.

[0039] The vibration assembly 21 includes a rotating column 215. The inner wall of the outer casing 201 is rotatably connected to the rotating column 215 via bearings. An eccentric column 216 is fixedly connected to the inner side of the rotating column 215. A connecting rod 217 is rotatably connected to the outer wall of the eccentric column 216 via bearings. A second motor 206 drives the rotating column 215 to rotate. A movable frame 211 is movably connected to the inner wall of the outer casing 201. A protruding plate 212 is fixedly connected to the side of the movable frame 211 away from the rotating column 215. A partition 213 is fixedly connected to the inner side of the movable frame 211. A connecting column 214 is fixedly connected to the outer wall of the partition 213. The outer wall of 214 is rotatably connected to the connecting rod 217 via a bearing. The rotation of the rotating column 215 drives the protruding plate 212 to move via the connecting rod 217. During the falling process, the material will come into contact with the shaking component 21. The second motor 206 drives the rotating column 215 to rotate, and the rotating column 215 drives the eccentric column 216 to rotate eccentrically. The eccentric column 216 pulls the connecting column 214 via the connecting rod 217 connected by the bearing, thereby causing the movable frame 211 and the protruding plate 212 to reciprocate and shake. Under this shaking action, the broken material is continuously scattered and redistributed, effectively preventing plastic broken material from adhering to or agglomerating with ferromagnetic particles.
