Description

Technical Field

[0001] This invention relates to the field of scrap steel recycling technology, and in particular to a scrap steel recycling and crushing equipment. Background Technology

[0002] Scrap steel generally refers to steel scrap that is not used as a product during the steelmaking process, as well as steel materials from equipment and components that are scrapped after use. For example, steel is the dominant component in equipment and tools such as automobiles and home appliances. Because scrap steel has good recycling value, scrap steel recycling is also an effective way to make full use of resources. In the process of scrap steel recycling, larger scrap steel is usually crushed by a special crusher to obtain smaller scrap steel, which facilitates subsequent processing.

[0003] However, it has been found that common scrap steel shredders typically require their feed hoppers to be positioned close to the outlet of the belt conveyor to guide the incoming scrap steel into the shredder for crushing. However, the feed hoppers of most shredders are fixed in position and cannot be adjusted vertically. When the shredder needs to be used in conjunction with belt conveyors of different heights, it is difficult to move the feed hopper to a position close to the conveyor, resulting in poor compatibility and limited applicability. Furthermore, the small-volume scrap steel after crushing tends to accumulate in the discharge channel during the discharge process, requiring manual clearing, which reduces automation and increases the workload of the workers.

[0004] Therefore, it is necessary to provide a scrap steel recycling and crushing equipment to solve the above-mentioned technical problems. Summary of the Invention

[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0038] First embodiment:

[0039] Please refer to the following: Figures 1-9In the first embodiment of the present invention, the scrap steel recycling and crushing equipment includes: a support frame plate 1 and a crusher 2 fixedly installed above the support frame plate 1. A feed channel steel 3 is provided on the crusher 2, and four support legs are fixedly installed at the bottom of the support frame plate 1 for support. A gantry frame 4 is fixedly installed at the top of the support frame plate 1, and a guide channel steel 5 is provided inside the gantry frame 4. One side of the guide channel steel 5 extends into the feed channel steel 3. Two support plates 6 are fixedly installed inside the gantry frame 4, and the same lifting screw 7 is rotatably installed on the two support plates 6. A hollow frame 8 is threaded onto the lifting screw 7, and the top of the hollow frame 8 is fixedly connected to the guide channel steel 5. Furthermore, slide rails are provided on the inner walls of both sides of the gantry frame 4, and sliding strips are slidably installed in both slide rails. The two sliding bars are fixedly connected to the guide channel steel 5 on their adjacent sides, thus restricting the guide channel steel 5 and allowing it to be adjusted up and down by the rotation of the lifting screw 7. To drive the lifting screw 7 to rotate, a first drive motor is fixedly installed on the top of the support frame plate 1. The output shaft of the first drive motor and the lifting screw 7 are both fitted with second full-tooth round teeth, which mesh with each other. A discharge channel steel 9 is located below the support frame plate 1, corresponding vertically to the discharge port of the crusher 2. A discharge port is opened on the support frame plate 1 between the crusher 2 and the discharge channel steel 9, allowing the crushed scrap steel to be discharged smoothly. A vertical connecting plate 10 is fixedly installed at the bottom of the support frame plate 1. A support platform 11 is fixedly installed, and two guide columns 12 are slidably installed on the support platform 11. The top of the two guide columns 12 is fixedly installed on the same mounting platform 13. The top of the mounting platform 13 is fixedly connected to the discharge channel steel 9, and the bottom of the two guide columns 12 is fixedly installed on the same linkage bar 14. Multiple first compression springs 15 are fixedly installed on the top of the support platform 11, and the top of each of the multiple first compression springs 15 is fixedly connected to the mounting platform 13. The first compression springs 15 have a large elastic bearing capacity, and they cannot be compressed by the crushed scrap steel alone without external pulling force. A first toothed column 16 is fixedly installed on the top of the linkage bar 14. A backrest plate 17 is fixedly installed on the bottom of the support frame plate 1, and an active rotating shaft 18 is rotatably installed on the backrest plate 17. A first missing tooth 19 is fixedly fitted onto the hollow frame 8, which is adapted to a first tooth post 16. The first missing tooth 19 and the first tooth post 16 can form intermittent meshing, thereby causing the discharge channel steel 9 to vibrate up and down, so that the scrap steel inside can be discharged smoothly. A connecting baffle plate 28 is fixedly installed on the outer wall of the hollow frame 8 away from the crusher 2, and a cross frame platform 29 is fixedly installed on one side of the connecting baffle plate 28. Two movable rods 35 are slidably installed on the cross frame platform 29. The top of the two movable rods 35 is fixedly installed with the same connecting piece 36. Two impact heads 38 are fixedly installed on the top of the connecting piece 36. The impact heads 38 are tangent to the bottom of the guide channel steel 5, and impact occurs between the impact heads 38 and the guide channel steel 5.This allows the guide channel steel 5 to also have a certain degree of vibration, thereby smoothly guiding the scrap steel within it into the feed channel steel 3.

[0040] In this method, in order to prevent scrap steel from overflowing from the front end of the feed channel 3, a baffle plate is fixedly installed at the bottom of the guide channel 5. The baffle plate is in contact with the feed channel 3 and is relatively long, so as to accommodate the adjustment of the highest and lowest positions of the guide channel 5.

[0041] In this configuration, to provide a driving force for the up-and-down oscillation of the discharge channel steel 9, a second drive motor is fixedly installed on one side of the back plate 17. Its output shaft is fixedly connected to one end of the drive shaft 18. The operation of the second drive motor drives the first toothed round tooth 19 to rotate, intermittently meshing with the first toothed column 16. To ensure smooth material discharge within the guide channel steel 5, a driven shaft 20 is rotatably installed on the back plate 17. Synchronous pulleys are fixedly fitted on both the drive shaft 18 and the driven shaft 20, and the same synchronous belt is fitted onto both pulleys. Two supports are fixedly installed on the back plate 17. The same first linkage rod 23 is rotatably mounted on two supports. A first bevel tooth 21 is fixedly sleeved on the driven shaft 20. A second bevel tooth 22 is fixedly mounted on the top of the first linkage rod 23. The first bevel tooth 21 and the second bevel tooth 22 mesh with each other. A swivel rod 24 is rotatably mounted on the support frame plate 1. The bottom end of the swivel rod 24 extends to the bottom of the support frame plate 1. Both the swivel rod 24 and the first linkage rod 23 are fixedly sleeved with first full-tooth round teeth 25. The two first full-tooth round teeth 25 mesh with each other. A cylindrical sleeve 26 is rotatably mounted on the connecting folding plate 28. The bottom of the cylindrical sleeve 26 is open. The top end of the swivel rod 24 extends into the cylindrical sleeve 26 and is fixed. A locking rod 27 is installed, and two sliding openings are provided on the outer wall of the cylindrical sleeve 26. The two ends of the locking rod 27 pass through the two sliding openings and contact the inside of the sliding openings. This ensures the sliding relationship between the locking rod 27 and the cylindrical sleeve 26, allowing the rotating rod 24 to rotate the cylindrical sleeve 26, without hindering the cylindrical sleeve 26 from rising and falling with the guide channel steel 5. A side plate 30 is fixedly installed at the bottom of the cross frame 29, and a second linkage rod 31 is rotatably installed on the side plate 30. A third bevel tooth 32 is fixedly fitted on the cylindrical sleeve 26, and a fourth bevel tooth 33 is fixedly installed at the end of the second linkage rod 31 near the cylindrical sleeve 26. The third bevel tooth 32 meshes with the fourth bevel tooth 33. A second tooth post 37 is fixedly installed at the bottom of the connecting piece 36. A second toothed round tooth 34 is fixedly installed at the end of the second linkage rod 31 away from the cylindrical sleeve 26. The second toothed round tooth 34 and the second tooth post 37 are compatible and can also form intermittent meshing, thereby driving the impact head 38 to collide with the guide channel steel 5 intermittently, so that the scrap steel in the guide channel steel 5 can be discharged smoothly. A second compression spring 39 is sleeved on both movable rods 35. The top ends of the two second compression springs 39 are fixedly connected to the connecting piece 36, and the bottom ends of the two second compression springs 39 are fixedly connected to the cross frame 29.

[0042] In this embodiment

[0043] In the initial state, the guide channel steel 5 is located below the tail end of the external belt feeder;

[0044] When scrap steel needs to be crushed, if the guide channel steel 5 is far from the bottom of the belt feeder, the first drive motor can be started in the forward direction. By using the meshing of the two second full-tooth round teeth, the lifting screw 7 can be driven to rotate. At this time, by using the threaded engagement between it and the hollow frame 8, and under the sliding limit of the slide rail and slide bar, the guide channel steel 5 begins to rise. After the guide channel steel 5 rises to a height that is very close to the tail end of the belt feeder, the first drive motor is turned off.

[0045] Subsequently, the external belt feeder is started to feed the scrap steel. The scrap steel falls into the feed channel 3 through the guide channel 5 and finally enters the crusher 2 for crushing. After crushing, the small-volume scrap steel is discharged through the discharge port and falls into the discharge channel 9. Then, it falls into the next conveyor mechanism.

[0046] During the feeding and discharging process, to prevent excessive scrap steel from accumulating in the guide channel 5 and to prevent crushed scrap steel from getting stuck in the discharge channel 9, the second drive motor can be started simultaneously during the crushing process. Its output shaft drives the drive shaft 18 to rotate, and the first toothed round tooth 19 on it rotates accordingly. When the teeth on the toothed round tooth 19 contact the teeth on the first toothed column 16, the two mesh, thereby driving the first toothed column 16 and the linkage bar 14 to descend. During the descent, the discharge channel 9 also descends, and at the same time, multiple first compression springs 15 are compressed. When the first toothed round tooth 19 separates from the first tooth post 16, the first compression spring 15, which is in a compressed state, will release its elastic force instantly, carrying the linkage bar 14 and the discharge channel steel 9 upward. Finally, the linkage bar 14 will collide with the vertical connecting plate 10. Then, when the tooth on the first toothed round tooth 19 engages with the first tooth post 16 again, it will carry the discharge channel steel 9 downward. When they separate, the discharge channel steel 9 will rise again, thus forming a reciprocating up and down oscillation. This allows the scrap steel in the discharge channel steel 9 to be discharged during the oscillation process, reducing the occurrence of blockage and poor flow.

[0047] While the driving shaft 18 rotates, the driven shaft 20 rotates simultaneously through the transmission between the synchronous pulley and the synchronous belt, which in turn drives the first bevel gear 21 to rotate. At this time, the transmission between the first bevel gear 21 and the second bevel gear 22 drives the first linkage rod 23 to rotate, and under the meshing of the two first full-tooth round teeth 25, it drives the rotating connecting rod 24 to rotate, which in turn drives the cylindrical sleeve 26 and the third bevel gear 32 on it to rotate. At this time, the meshing between the third bevel gear 32 and the fourth bevel gear 33 drives the second linkage rod 31 to rotate, and the second missing tooth round tooth 34 on the second linkage rod 31 begins to rotate. When the teeth on it contact the teeth on the second tooth post 37, the two mesh. As the connecting piece 36 and the impact head 38 descend, the second compression spring 39 gradually compresses. When the teeth on the second missing tooth 34 separate from the teeth on the second tooth post 37, the compressed second compression spring 39 releases its elasticity, causing the impact head 38 to rise rapidly and collide with the guide channel steel 5, giving the guide channel steel 5 a vibrational force, which can generate vibration in the scrap steel inside, allowing the scrap steel to slide out smoothly. When the teeth on the second missing tooth 34 mesh with the teeth on the second tooth post 37 again, the impact head 38 descends again. When they separate again, the impact head 38 strikes the guide channel steel 5 again, and so on, thus generating a vibrational force to assist in the discharge process.

[0048] Compared with related technologies, the scrap steel recycling and crushing equipment provided by this invention has the following beneficial effects:

[0049] ① By means of the threaded connection between the lifting screw 7 and the hollow frame 8, the guide channel steel 5 can be raised and lowered, so as to make adaptive adjustments according to the position of the tail end of the external belt feeder, thereby improving the applicability. In addition, the baffle plate can prevent scrap steel from overflowing.

[0050] ② By intermittently meshing the first missing tooth circular tooth 19 and the first tooth pillar 16, as well as the second missing tooth circular tooth 34 and the second tooth pillar 37, the discharge channel steel 9 can be oscillated up and down to discharge material, ensuring smooth discharge without blockage. At the same time, the impact head 38 can impact the guide channel steel 5 to generate its own oscillation force, which can also ensure that the scrap steel in the guide channel steel 5 can be smoothly discharged into the feed channel steel 3, thus ensuring the continuity and stability of the crushing process. Moreover, only one second drive motor is set up, and the above two oscillating discharge methods can be formed through the linkage of components such as the first linkage rod 23 and the second linkage rod 31, reducing the use of electrical components and lowering costs.

[0051] Second embodiment:

The top of the magnetically attracted perforated plate 51 contacts the movable connecting platform 52. The movable connecting platform 52 has multiple slots, and each slot is fitted with a retaining strip 53. The bottom of each retaining strip 53 is fixedly connected to the magnetically attracted perforated plate 51. A crossbeam 54 is bolted to one side of the outer wall of the wastewater tank 49. A reduction motor 55 is fixedly mounted on the top of the crossbeam 54, and a rotating disk 5 is fixedly mounted on its output shaft. 6. An eccentric rod 57 is fixedly installed on the rotating disk 56. A linkage arm 58 is rotatably installed on the eccentric rod 57. One end of the linkage arm 58 is hinged to the movable connecting platform 52. A slide rail is fixedly installed on the top of the crossbeam 54. A sliding column is slidably installed on the slide rail. The top of the sliding column is fixedly connected to the movable connecting platform 52. Through the operation of the reduction motor 55, the movable connecting platform 52 can move back and forth with the magnetic adsorption porous plate 51, which can stir the sewage and drive the metal dust in it to roll and be more thoroughly adsorbed on the magnetic adsorption porous plate 51.

[0057] In the above method, in order to facilitate the removal of the magnetically adsorbed porous plate 51 and scrape off the metal powder attached to it, locking holes 59 are provided on multiple retaining strips 53. A U-shaped frame 60 is fixedly installed on the top of the movable connecting platform 52. A transverse screw 61 is rotatably installed inside the U-shaped frame 60. Multiple transverse sliding pieces 62 are threaded on the transverse screw 61. Insert rods 63 are fixedly installed on each of the multiple transverse sliding pieces 62. The multiple insert rods 63 pass through the multiple locking holes 59 and contact the inner wall of the corresponding locking holes 59. A crossbar is fixed inside the U-shaped frame 60. The crossbar passes through the multiple transverse sliding pieces 62 and slides through the multiple transverse sliding pieces 62 to restrict the transverse sliding pieces 62 so that they can only move in a straight line.

[0058] In this embodiment

[0059] During the crushing process, a large amount of dust containing metal powder is generated at the feed inlet and discharge outlet. In order to collect these metal powders that still have utilization value, and to reduce the harm of this dust to the health of workers and the impact on the environment, the exhaust fan 40 and the external water pump can be started during the crushing process. The external water pump draws clean water and pumps it into the axial water pipe 45, which is then sprayed out through the first nozzle 47 and the second nozzle 64. Then the third drive motor is started. Through the meshing of the two third full-tooth round teeth, the axial water pipe 45 and multiple transverse branch pipes 46 can be rotated, thus forming a series of water columns in the spray tank 44.

[0060] Meanwhile, as the exhaust fan 40 operates, a negative pressure is formed around the multiple horn port pipes 43, and dust containing metal dust enters the main ventilation pipe 41 and the branch ventilation pipe 42, and then enters the spray tank 44. When it enters, the sprayed water will suppress the dust, and the dust and metal dust will sink with the water and flow into the sewage tank 49 through the drainage pipe 50. Then, the reduction motor 55 is started, and its output shaft drives the rotating disk 56 to rotate. During the rotation, the hinge of the eccentric rod 57 and the linkage arm 58 can move the movable connecting table 52 back and forth. During the movement, multiple magnetic adsorption perforated plates 51 move left and right in the sewage, which can stir the sewage, so that the metal dust in it is adsorbed on the magnetic adsorption perforated plates 51.

[0061] When the sewage tank 49 is almost full of sewage, the crushing operation can be stopped. Then, the crossbeam 54 is removed from one side of the sewage tank 49, and the magnetically attracted perforated plate 51 is pulled out of the sewage tank 49. Then, the transverse screw 61 is rotated, and the threaded engagement between it and the transverse moving plate 62 is used to move multiple insert rods 63 together. Finally, all the insert rods 63 are moved out of the corresponding locking holes 59. The magnetically attracted perforated plate 51 can then be removed. After scraping off the metal powder on it, it can be installed on the movable connecting table 52, and then it can be used again.

[0062] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
