Description

Technical Field

[0001] This invention relates to the field of scrap steel recycling technology, specifically to an integrated scrap steel and scrap iron recycling and processing production line. Background Technology

[0002] As a renewable and recyclable metal resource, scrap steel and scrap iron are an important raw material supplement in the steel industry. The recycling and reprocessing of scrap metal can effectively reduce the amount of mineral resources mined and reduce energy consumption in industrial production, and occupies an important position in resource recycling and green industrial development.

[0003] In actual operation, existing recycling production lines often contain a large amount of solid impurities and dust particles, such as cement lumps and paint chips, after the material is crushed. Conventional equipment has relatively simple impurity and dust removal structures, which cannot achieve thorough pre-treatment. Impurities and dust can easily enter the core mechanisms such as conveying and transmission along with the metal fragments. Over time, this can cause jamming, blockage, and accelerated wear of the equipment's transmission components, significantly increasing the probability of equipment failure and maintenance frequency, and shortening the equipment's lifespan. At the same time, traditional metal material conveying and adsorption structures mostly rely on continuous external power supply. The electromagnetic structure adsorbs and conveys metal fragments, and the fully powered operation not only has high energy consumption and low energy efficiency, but also relies heavily on manual or external control systems for power supply and shutdown, resulting in poor automation adaptability.

[0004] The inventors of this application discovered in their research that the core defect of the aforementioned prior art is that after the material is crushed, the remaining fine metal fragments will continue to intrude into the gaps of the equipment and the transmission structure. Summary of the Invention

[0005] This invention provides an inventive device that solves the problem that after material is crushed, residual fine metal fragments will invade the gaps of the equipment and the transmission structure. It achieves the effect of effectively intercepting metal fragments without external power supply and preventing the transmission components from jamming and wearing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated scrap steel and scrap iron recycling production line, comprising a support frame, a crusher, a sorting device, and an integration device. The crusher, sorting device, and integration device are sequentially installed between multiple supports. A collection rack is installed at the bottom of each support frame. A motor is installed at one end of each support frame. Two connecting shafts are rotatably connected to the top of each support frame. Synchronous gears are installed at both ends of each connecting shaft. Synchronous gears are meshed with a synchronous toothed belt. Multiple connecting pipes are installed on the inner wall of the synchronous toothed belt. A conveying plate is slidably connected to the inner wall of two of the connecting pipes. Electromagnetic components are provided at both ends of each conveying plate. Pulleys are rotatably connected to both ends of each conveying plate. Fixed bolts one and two are threadedly connected to both ends of each conveying plate. A gear two is installed between fixed bolts one and two. Two racks two are installed on the inner wall of both ends of each support frame. A cleaning component is provided at the bottom of the crusher.

[0007] By adopting the above technical solution: electromagnetic components are set at both ends of the conveyor plate. When motor one drives the synchronous toothed belt to rotate through the connecting shaft and synchronous gear, the two synchronous toothed belts drive multiple conveyor plates to move through multiple connecting pipes. When the synchronous toothed belt moves, the electromagnetic components generate magnetic force on both sides of the conveyor plate, causing it to attract metal slag. Before the conveyor plate moves below the synchronous toothed belt, the gear two on both sides of the conveyor plate drives the conveyor plate to rotate through the rack two. At the same time, the electromagnetic components no longer generate magnetic force, causing the metal slag on the conveyor plate to fall onto the collection rack, preventing the metal slag from entering the transmission mechanism on the support, thereby avoiding the transmission components from being stuck or worn due to metal impurities.

[0008] Preferably, the cleaning assembly includes a filter screen frame rotatably connected to one end of the crusher, and a second motor and a fan are installed at the other end of the crusher. A rotating shaft is installed at the output end of the second motor, and a collection bag is installed at one end of the fan.

[0009] Preferably, the rotating shaft is rotatably connected to the bottom end of the filter screen frame and to the other end of the crusher.

[0010] Preferably, the electromagnetic component includes a connecting frame, two connecting frames are respectively installed at both ends of the conveyor plate, a fixing bolt is slidably connected to the outer wall of the connecting frame, a transmission gear ring is rotatably connected to one end of the connecting frame, multiple micro generators are installed on the outer wall of the connecting frame, a gear is installed at the input end of the micro generator, two racks are installed on the inner wall of the bottom end of the bracket, two electromagnetic coil rods are installed on the inner wall of the conveyor plate, connectors are installed at both ends of the conveyor plate, and the connecting frame is slidably connected to the outer wall of one end of the connecting pipe.

[0011] Preferably, the inner wall of the connector is provided with a first wire; the inner wall of the connecting frame is provided with a second wire, and one end of the second wire is connected to multiple micro generators.

[0012] Preferably, one end of the first wire is in contact with the electromagnetic coil rod, and the other end is in contact with the other end of the second wire.

[0013] Preferably, the plurality of gears are meshed with the inner tooth ends of the transmission gear ring, and the plurality of transmission gear rings are meshed with the tooth ends of the rack.

[0014] Preferably, the two gears are slidably connected at both ends of the conveyor plate, and the fixing bolts are slidably connected to the outer wall of the gears.

[0015] Preferably, a plurality of the conveyor plates are slidably connected to the top of the bracket, and one of the connecting shafts is fixedly connected to the output end of the motor.

[0016] Preferably, the plurality of pulleys are rotatably connected to the inner wall of the top of the bracket, and the second gear is meshed with the tooth end of the second rack.

[0017] This invention provides an integrated scrap steel and iron recycling production line. It has the following beneficial effects: 1. This invention uses electromagnetic components at both ends of the conveyor plate, combined with the meshing transmission structure of rack and pinion and gear, to generate magnetic force to attract the metal scrap produced by the crusher when the conveyor plate moves. When it flips, it automatically loses its magnetism to complete the material discharge, thus avoiding the metal scrap from getting stuck and wearing the core components of the equipment, and achieving the effect of automated metal scrap adsorption and unloading.

[0018] 2. The bottom of the crusher of this invention is equipped with a reciprocating rotating filter screen frame combined with a fan dust removal structure. The reciprocating shaking of the filter screen frame can remove impurities mixed in the metal fragments, avoid mesh blockage, and improve screening accuracy and efficiency. Combined with the sealed dust removal design of the fan and collection bag, dust can be collected in a concentrated manner, preventing dust from entering the conveying and transmission mechanism, improving the working environment, and avoiding dust pollution that may harm the health of operators.

[0019] 3. This invention employs a self-generating electromagnetic component structure. The meshing transmission of rack one, transmission gear ring, and gear one drives a micro-generator to power the electromagnetic coil rod, generating magnetic force. This structure can automate the adsorption and release of metal slag without an external power source, overcoming the limitations of traditional electromagnetic adsorption equipment that relies on external power. This reduces production line power consumption, improves the level of automation and overall energy efficiency, simplifies power supply layout, and reduces wiring and subsequent power maintenance costs.

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 -Appendix Figure 10This invention provides an integrated scrap steel and scrap iron recycling production line, including a support frame 1, a crusher 2, a sorting device 3, and an integration device 4. The crusher 2, the sorting device 3, and the integration device 4 are sequentially installed between multiple supports 1. A collection rack 14 is installed at the bottom of each support 1, and a motor 5 is installed at one end of each support 1. Two connecting shafts 6 are rotatably connected to the top of each support 1. Synchronous gears 7 are installed at both ends of each connecting shaft 6. The teeth of the synchronous gears 7 are meshed with a synchronous toothed belt 8. Multiple connecting pipes 9 are installed on the inner wall of the synchronous toothed belt 8. A conveying plate 10 is slidably connected to the inner wall of two connecting pipes 9. Electromagnetic components 11 are provided at both ends of each conveying plate 10. The conveyor plate 10 is rotatably connected to a pulley 18. Both ends of the conveyor plate 10 are threadedly connected to a fixing bolt 15 and a fixing bolt 16. A gear 12 is installed between the fixing bolt 15 and the fixing bolt 16. Two racks 13 are installed on the inner walls of both ends of the support 1. A cleaning component 17 is provided at the bottom of the crusher 2. Multiple conveyor plates 10 are slidably connected to the top of the support 1. One of the connecting shafts 6 is fixedly connected to the output end of the motor 5. Multiple pulleys 18 are rotatably connected to the inner wall of the top of the support 1. Gear 12 is meshed with the tooth ends of rack 13. Two gears 12 are slidably connected to both ends of the conveyor plate 10. The fixing bolt 16 is slidably connected to the outer wall of gear 12.

[0024] Specifically, by installing electromagnetic components 11 at both ends of the conveyor plate 10, when the motor 5 drives the synchronous toothed belt 8 to rotate via the connecting shaft 6 and the synchronous gear 7, the two synchronous toothed belts 8 drive multiple conveyor plates 10 to move via multiple connecting pipes 9. When multiple conveyor plates 10 move on the synchronous toothed belt 8, the electromagnetic components 11 are activated, generating a strong magnetic force on both sides of the conveyor plate 10, thereby effectively adsorbing and carrying the metal slag separated from the crusher 2. As the conveyor plates 10 are continuously driven forward by the synchronous toothed belt 8, before they move to the lower rotation path of the synchronous toothed belt 8, the gears 12 on both sides of the conveyor plate 10 will mesh with the racks 13 fixed to the inner wall of the support 1. This meshing action will drive the conveyor plate 10 to rotate 180 degrees around its axis, achieving flipping. At the same time, the control system will cut off the power supply to the electromagnetic components 11, causing them to instantly lose their magnetic force. As the magnetic force disappears and the conveyor plate 10 has completed its rotation, the metal slag that was originally adsorbed on the plate surface will completely detach under the action of gravity and fall accurately into the collection rack 14 set below. This actively intercepts and removes metal debris, effectively preventing these conductive or hard metal slags from entering and getting stuck inside the transmission mechanism on the support 1, thereby protecting key components such as gears and bearings from wear or damage and ensuring the long-term stable operation of the entire recycling conveyor line.

[0025] Please see the appendix Figure 1 -Appendix Figure 4The cleaning component 17 includes a filter screen frame 1701, which is rotatably connected to one end of the crusher 2. The other end of the crusher 2 is equipped with a motor 1703 and a fan 1704. The output end of the motor 1703 is equipped with a rotating shaft 1702. One end of the fan 1704 is equipped with a collection bag. The rotating shaft 1702 is rotatably connected to the bottom end of the filter screen frame 1701 and the other end of the crusher 2.

[0026] Specifically, by rotatably connecting the filter frame 1701 and the rotating shaft 1702 to both ends of the crusher 2, and slidably connecting the other end of the filter frame 1701 to the rotating shaft 1702, when the motor 1703 drives the rotating shaft 1702 to rotate, the rotating shaft 1702 drives the filter frame 1701 to rotate repeatedly. This allows the filter frame 1701 to screen the metal fragments produced by the crusher 2, allowing cement blocks and metallic paint in the metal fragments to be screened onto the collection rack 14. Simultaneously, the blower 1704 absorbs the dust produced by the crusher 2 into a collection bag at one end of the blower 1704, thereby preventing dust from entering the conveying device. This structure not only improves screening efficiency but also reduces the frequency of manual cleaning. During the reciprocating rotation of the filter frame 1701, fine particles adhering to its surface are shaken off, preventing clogging of the mesh. At the same time, the coordinated design of the blower 1704 and the collection bag achieves sealed dust collection, reducing air pollution in the working environment and ensuring the health and safety of operators.

[0027] Please see the appendix Figure 4 -Appendix Figure 10 The electromagnetic component 11 includes a connecting frame 1101. Two connecting frames 1101 are respectively installed at both ends of the conveyor plate 10. A fixing bolt 15 is slidably connected to the outer wall of the connecting frame 1101. A transmission gear ring 1102 is rotatably connected to one end of the connecting frame 1101. Multiple micro generators 1103 are installed on the outer wall of the connecting frame 1101. A gear 1104 is installed at the input end of the micro generator 1103. Two racks 1105 are installed on the inner wall of the bottom end of the bracket 1. Two electromagnetic coil rods 1106 are installed on the inner wall of the conveyor plate 10. Both ends of 10 are equipped with connectors 1107. Connector 1101 is slidably connected to the outer wall of one end of connector 9. Wire 1 is provided on the inner wall of connector 1107. Wire 2 is provided on the inner wall of connector 1101, and one end of wire 2 is connected to multiple micro generators 1103. One end of wire 1 is in contact with electromagnetic coil rod 1106, and its other end is in contact with the other end of wire 2. Multiple gears 1104 are meshed with the inner tooth end of transmission gear ring 1102, and multiple transmission gear rings 1102 are meshed with the tooth end of rack 1105.

[0028] Specifically, multiple gears 1104 mesh with the inner teeth of one end of the transmission gear ring 1102, and the outer teeth of the other end of the transmission gear ring 1102 mesh with the rack 1105. When the two synchronous belts 8 drive multiple conveyor plates 10 to move through multiple connecting pipes 9, the rack 1105 drives the multiple gears 1104 to rotate rapidly through the transmission gear ring 1102, causing multiple micro generators 1103 to generate current. This current is then transmitted to both ends of the electromagnetic coil rod 1106 inside the conveyor plate 10 through the wires 2 and 1 inside the connecting frame 1101 and the connecting piece 1107, causing the electromagnetic coil rod 1106 to generate magnetic force and attract the metal slag on the conveyor plate 10. When the transmission gear ring 1102 no longer meshes with the rack 1105, the electromagnetic coil rod 1106 no longer generates magnetic force, causing the metal slag on the conveyor plate 10 to fall onto the collection rack 14, thus preventing the metal slag from entering the support 1. The adsorption and release processes are completed without the need for external power supply, which improves the overall energy efficiency and automation level of the system.

[0029] Work process: The production line is mainly composed of a support frame 1, a crusher 2, a sorting device 3 and an integration device 4 assembled in sequence. It is equipped with a conveying mechanism, a cleaning component 17 and a self-generating electromagnetic adsorption mechanism to realize the integrated automated operation of scrap steel and scrap iron crushing, impurity removal, dust removal, adsorption conveying and automatic unloading.

[0030] During operation, after the material is crushed by crusher 2, it undergoes pre-purification by cleaning component 17: motor 2 1703 drives filter screen 1701 to oscillate back and forth, screening out solid impurities such as cement blocks and paint chips. A matching fan 1704, in conjunction with a collection bag, achieves sealed dust collection, effectively preventing dust and impurities from entering the transmission mechanism. Motor 1 5 drives multiple sets of conveyor plates 10 to circulate via synchronous gear 7 and synchronous toothed belt 8. During the movement of the conveyor plates 10, the transmission gear ring 1102 meshes with rack 1105, driving the micro-generator 1103 to generate electricity autonomously, supplying power to the electromagnetic coil rod 1106 to produce magnetic force, achieving stable adsorption and conveying of the crushed metal slag. When the conveyor plate 10 reaches the rotation position, gear 2 12 meshes with rack 2 13, driving the conveyor plate 10 to complete a 180° flip. Simultaneously, the transmission gear ring 1102 disengages, power generation is cut off, the electromagnetic component 11 loses magnetism, and the metal slag automatically falls to the collection rack 14 under gravity for collection.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
