DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 8 A scrap steel crushing and recycling device comprises a feed box 1 for providing a space for putting scrap steel; a transfer box 2 for horizontally conveying the crushed steel sheets; an output box 3; a pressing box 4 for collecting the crushed steel sheets; and a crushing mechanism 5 for crushing large scrap steel into small steel sheets.

[0032] In this embodiment, the pressing and discharging mechanism 6 is used to collect the crushed steel sheets and press them into cakes; the crushing mechanism 5 includes a driving device and a rotating device. The driving device drives the rotating device to perform relative extrusion crushing on the scrap steel. While the driving device drives the rotating device, it also drives the pressing and discharging mechanism to press the crushed steel sheets into cakes, and automatically discharge and collect them.

[0033] Furthermore, the driving device includes a driving motor 501, a mounting frame 8 is fixedly connected to one side of the transfer box 2, the driving motor 501 is mounted on the mounting frame 8, a driving sprocket 504 is fixedly connected to the output shaft of the driving motor 501, a driving sprocket 505 is connected to the surface of the driving sprocket 504 through a chain transmission, and the driving sprocket 505 is connected to the rotating device. The rotating device includes two crushing wheels 506, the driving sprocket 505 is fixedly connected to one of the crushing wheels 506 through a shaft, one end of the two crushing wheels 506 is fixedly connected to a large gear 507, and the two large gears 507 are meshed with each other, and the two crushing wheels 506 are located inside the feed box 1. The driving motor 501 rotates, which in turn drives the driving sprocket 504 to rotate, and the chain transmission drives one of the crushing wheels 506 to rotate. When one of the crushing wheels 506 rotates, it will drive the rotation of the large gear 507. The meshing of the two large gears 507 will form a relative crushing effect on the two crushing wheels 506, and the fragments will enter the interior of the transfer box 2 through the channel at the bottom of the feed box 1.

[0034] Furthermore, the output end of the driving motor 501 is also connected to a driving shaft 502, which is rotatably connected to the inside of the transfer box 2, and a spiral blade 503 is fixedly connected to the surface of the driving shaft 502, which is located inside the transfer box 2. A discharge port is provided at the bottom of the transfer box 2, and the output box 3 is connected to the transfer box 2. The rotation of the driving motor 501 directly drives the rotation of the driving shaft 502, and the driving shaft 502 drives the spiral blade 503 of the spiral structure to rotate, thereby realizing the horizontal transfer of the fragments, and then transferring them to the opening position on the left side, dropping them into the inside of the output box 3, and carrying them on the conical surface of the pressure drop 603.

[0035] In addition, the pressing and discharging mechanism 6 includes a crank 601, the eccentric part of the crank 601 is rotatably connected to the lifting rod 602, the bottom of the lifting rod 602 is rotatably connected to the pressure drop 603, the pressure drop 603 is slidably connected to the inside of the output box 3, and a movable plate 604 is arranged below the pressure drop 603. A feed trough is arranged inside the output box 3, and the pressure drop 603 is a frustum-shaped structure. Because the frustum-shaped structure can provide a certain degree of sliding channel for the steel sheet. When the pressure drop 603 is in the lifting stage, after the bottom end is flush with the feed trough, the fragments located above the pressure drop 603 will slide obliquely to the bottom of the output box 3 through the feed trough, and be located above the movable plate 604, and then they are in a state to be pressed. The feed trough mainly provides another channel after the pressure drop 603 moves up, so that the crushed steel sheet can automatically slide to the bottom of the pressure drop 603, which is convenient for the next downward movement of the pressure drop 603 and is pressed and shaped.

[0036] In addition, an extension shaft 605 is fixedly connected to one side of the crank 601, and a spiral groove 606 is provided on the surface of the extension shaft 605. A ring body is slidably connected to the surface of the extension shaft 605, and a sliding pin 609 is provided in the ring body. The sliding pin 609 is slidably connected to the inside of the spiral groove 606. A sliding frame 607 is connected to the ring body, and the bottom of the sliding frame 607 is connected to the movable plate 604. The sliding frame 607 is slidably connected to the pressing box 4. When the crank 601 rotates, the extension shaft 605 is synchronously driven to rotate, and then the sliding groove 606 and the sliding pin 609 are used to drive the sliding frame 607 on the ring body to reciprocate horizontally left and right. The rotating groove 606 here is similar to the spiral groove of the reciprocating screw. The ring body is controlled to move horizontally left and right by rotation, and the limiting sliding of the limiting rod 610 is used to control the lateral movement of the movable plate 604 connected to the bottom. After moving to the right, the pressed and flattened steel sheet will be controlled to enter the inside of the hole groove 608. After sliding to the left, the steel sheet inside the hole groove 608 will be moved out of the space under the pressure drop 603, so that the plane of the movable plate 604 is slid again to the bottom of the pressure drop 603, so as to facilitate its second flattening and forming.

[0037] It is worth noting that a hole slot 608 is provided on the movable plate 604, and the movable plate 604 is slidably connected to the inside of the pressing box 4. A limit rod 610 is slidably connected to the sliding frame 607, and one end of the limit rod 610 is fixed to the surface of the output box 3. The limit rod 610 can be used to control the lateral stable sliding of the sliding frame 607, because the overall sliding power of the sliding frame 607 is at the position of the top ring body, and the limit rod 610 is provided to avoid sliding tilting and blocking. The hole slot 608 can provide a falling space for the pressed fragments when the movable plate 604 moves to the right, and enter the inside of the hole slot 608. When it moves to the left, the steel sheet inside the hole slot 608 will be moved out, realizing automatic shaping and discharging after pressing.

[0038] It is worth mentioning that the cleaning mechanism 7 includes a filter screen 701, a cavity is provided inside the pressing box 4, a water pump is provided inside the cavity, the output end of the water pump is connected to a water pipe 702, one end of the water pipe 702 is connected to a nozzle 704, the nozzle 704 is connected to the transfer box 2, and a water leakage port 703 is opened on the movable plate 604. The interior of the pressing box 4 is provided with a cavity and is externally connected to a water pipe. The cleaning water will be sucked by the water pump inside the cavity, enter the interior of the water pipe 702, and then be discharged from the position of the nozzle 704 to spray and rinse the conveying steel sheets inside the transfer box 2. The flushing water will flow out from the position of the output box 3 along with the steel sheets, and then flow to the top of the movable plate 604, and flow back to the internal cavity of the pressing box 4 through multiple leaks 703. The sewage is filtered by the filter 701, and the filtered water flow will further flow back from the position of the water pipe 702 to the interior of the transfer box 2 through an external pipe, thereby realizing a cyclic reflux cleaning, thereby saving the use of water resources. The pressing box 4 is an openable structure, and the operator can take out the filter 701 from time to time to replace it to avoid blockage due to long-term use.

[0039] It is worth mentioning that the impurity removal mechanism 9 includes a support frame 906, one side of the support frame 906 is fixedly connected to a sliding push rod 907, one end of the sliding push rod 907 passes through the transfer box 2 and is connected to the ring body on the sliding frame 607, the bottom of the support frame 906 is connected to a frame plate 902, the frame plate 902 is slidably connected to the collection frame 201 installed at the bottom of the transfer box 2, the collection frame 201 is provided with a filter slot 901, a plurality of frame plates 902 are provided, and the plurality of frame plates 902 are connected in series through a support rod 904, a plurality of frame plates 902 are rotatably connected to a one-way push plate 903, and the bottom of the collection frame 201 is threadedly connected to a collection tank 905. Because there must be a certain degree of impurities inside the steel sheet during the cleaning and transportation process, if the equipment is running for a long time, the impurities will gradually follow the pressing process and be discharged together with the scrap steel, which will result in the need for further cleaning in the later stage. Therefore, a de-impurity mechanism 9 is set. When the steel sheet is cleaned, the internal impurities will enter the interior of the collection rack 201 through the filter groove 901. At the same time, when the sliding rack 607 circulates left and right, it will synchronously drive the support frame 906 to move horizontally through the sliding push rod 907. When the support frame 906 moves horizontally, it will drive the horizontal movement of the shelf plate 902. When the shelf plate 902 moves, it will drive the one-way push plate 903 to move right, and push the dirt inside the collection rack 201 to the right. Through the cyclic left and right movement, the impurities are continuously pushed in a step-by-step manner, thereby processing the impurities and reducing the impurity content in the scrap steel recycling process. The operator can take out the collection tank 905 from time to time to process the impurities, so the overall synchronization realizes the collection of impurities inside the transfer box 2 and can automatically push them, avoiding the synchronous recovery and discharge of impurities with the scrap steel.

[0040] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0041] The working principle is that the operator first needs to put the scrap steel into the feed box 1, and then control the rotation of the drive motor 501, and then drive the rotation of the drive sprocket 504, and use the chain transmission to drive one of the crushing wheels 506 to rotate. After that, when one of the crushing wheels 506 rotates, it will drive the rotation of the large gear 507. The engagement of the two large gears 507 will form a relative crushing effect on the two crushing wheels 506. Then, the fragments will enter the transfer box 2 through the channel at the bottom of the feed box 1. At this time, when the drive motor 501 rotates, it will also directly drive the rotation of the drive shaft 502, and the drive shaft 502 drives the spiral blade 503 of the spiral structure to rotate, thereby realizing the horizontal transfer of the fragments, and then transfer them to the opening position on the left, and drop them into the inside of the output box 3, and be carried on the conical surface of the weight 603. At this time, while the driving shaft 502 rotates, it will also synchronously drive the rotation of the crank 601. The eccentrically connected lifting rod 602 will drive it to pull up and down, thereby driving the weight 603 connected to it to move up and down. When the weight 603 is in the lifting stage, after the bottom end is flush with the feed trough, the fragments above the weight 603 will slide obliquely through the feed trough to the bottom of the output box 3, located above the movable plate 604. After that, with each rotation of the driving shaft 502, the weight 603 will be driven to move up and down to form a cycle. Therefore, when the weight 603 is pressed down, the fragments that slide to the bottom will be pressed into shape, forming a round cake shape, and the irregular steel sheets will be flattened for easy later recycling. At the same time, when the crank 601 rotates, the extension shaft 605 is synchronously driven to rotate, and then the sliding groove 606 and the sliding pin 609 are used to drive the sliding frame 607 on the ring body to move back and forth horizontally. The rotating groove 606 here is similar to the spiral groove of the reciprocating screw. The ring body is controlled to move horizontally to the left and right by rotating, and the limiting sliding of the limiting rod 610 is used to control the lateral movement of the movable plate 604 connected to the bottom. After moving to the right, the pressed and flattened steel sheet will be controlled to enter the inside of the hole groove 608. After sliding to the left, the steel sheet inside the hole groove 608 will be moved out of the space under the pressure drop 603, so that the plane of the movable plate 604 will slide again to the bottom of the pressure drop 603, so as to facilitate its second flattening and forming.The interior of the pressing box 4 is provided with a cavity and is externally connected to a water pipe. The cleaning water will be sucked by the water pump inside the cavity and enter the interior of the water pipe 702, and then be discharged from the position of the nozzle 704 to spray and rinse the conveying steel sheets inside the transfer box 2. The flushing water will flow out from the position of the output box 3 along with the steel sheets, and then flow to the top of the movable plate 604, and flow back to the internal cavity of the pressing box 4 through multiple leaks 703. The sewage is filtered by the filter net 701, and the filtered water flow will further flow back from the position of the water pipe 702 to the interior of the transfer box 2 through an external pipe, thereby realizing a cyclic reflux cleaning. The entire equipment integrates crushing, transfer, pressing and cleaning into one equipment, thereby reducing the footprint of large-scale continuous equipment and reducing investment costs. It also has a high degree of automation and higher efficiency in scrap steel recycling. In addition, the entire device is also provided with a de-impurity mechanism 9, because during the cleaning and conveying process of the steel sheet, there must be a certain degree of impurities inside it. If the equipment is operated for a long time, the impurities will gradually be discharged along with the scrap steel during the pressing process, which will result in the need for further cleaning in the later stage. Therefore, when the steel sheet is cleaned, the internal impurities will enter the interior of the collection rack 201 through the filter slot 901. At the same time, when the sliding rack 607 circulates left and right, it will synchronously drive the support frame 906 to move horizontally through the sliding push rod 907. When the support frame 906 moves horizontally, it will drive the shelf plate 902 to move horizontally. When the shelf plate 902 moves, it will bring The one-way push plate 903 moves rightward, pushing the dirt inside the collection rack 201 to the right. Afterwards, as multiple one-way push plates 903 are pushed, they will be pushed to the right layer by layer. When the one-way push plate 903 moves to the left, it will be driven by the resistance of impurities at the bottom, which will drive the one-way push plate 903 to rotate and make way. Therefore, the entire process can only push the impurities to the right in a one-way direction, and finally enter the collection tank 905. The operator can take out the collection tank 905 from time to time to process the impurities. Therefore, the overall system can synchronously collect the impurities inside the transfer box 2 and automatically push them, avoiding the impurities being recovered and discharged synchronously with the scrap steel.
