The utility model includes a workbench, with a crushing chamber fixedly installed at the upper end of the workbench. A feed hopper is fixedly connected to the upper part of the outer wall of the crushing chamber. This utility model utilizes a swing assembly; through the reciprocating motion of a telescopic hydraulic cylinder and a telescopic rod, multiple telescopic cylinders and movable plates swing up and down inside the chamber, creating a certain oscillation.

Description

Technical Field

[0001] This utility model relates to the field of pelletizers, specifically an alloy pelletizer for the production of ductile iron spheroidizing agents. Background Technology

[0002] Spheroidizing agents are certain metals or alloys added to molten iron to obtain spheroidal graphite cast iron. To improve the spheroidization quality of molten iron, spheroidizing agents are often made into cored wires and added to them. This requires spheroidizing agents to be crushed into small particles. The function of an alloy granulator is to crush the spheroidizing agent raw materials into granules that meet production requirements for subsequent processing.

[0003] Currently, in the existing alloy pelletizing mills for producing ductile iron spheroidizing agents, blocky or strip-shaped spheroidizing agent raw materials are fed into the crushing chamber through the feed inlet. An irregular gap is formed between the eccentric wheel at the top of the crushing chamber and the chamber wall. The eccentric wheel is driven by a motor to rotate at high speed. When the raw material falls, it is squeezed and impacted by the eccentric wheel and the chamber wall, and large pieces of raw material are crushed into particles. The crushed particles are discharged through the bottom discharge port. Some equipment has a built-in screen, and the coarse particles that do not meet the standards are screened out and sent back to the crushing chamber for secondary crushing through a reflux device to ensure that the finished product has a uniform particle size. However, there are some defects: the crushed ductile iron spheroidizing agent particles need to be screened through a screen to separate the finished product particles with uniform particle size and discharge them from the outlet. However, during this process, the coarse particles that do not meet the standards are easy to block the pores of the screen, which will prevent the subsequently crushed spheroidizing agent particles from passing through the screen smoothly to complete the screening, affecting the overall screening efficiency and the finished product separation effect. Utility Model Content

[0004] The purpose of this invention is to provide an alloy pelletizer for the production of spheroidizing agents for ductile iron, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions: An alloy pelletizer for producing spheroidizing agents for ductile iron includes a workbench, a crushing chamber fixedly installed at the upper end of the workbench, a feed hopper fixedly connected to the upper part of the outer wall of the crushing chamber, side plates fixedly installed at both ends of the crushing chamber, a screening screen plate slidably sleeved on the lower part of the inner wall of the crushing chamber, and a swinging component for swinging and cleaning the screen holes of the screening screen plate on one side of the inner wall of the workbench.

[0006] Preferably, a servo motor is fixedly installed at one end of one of the side plates. The output shaft of the servo motor is driven by a rotating rod. The rotating rod is rotatably sleeved inside the side plate. Multiple sets of fixed sleeves are fixedly sleeved at equal intervals on the outer side of the rotating rod. The inner wall of each set of fixed sleeves is provided with a sliding groove. A sliding block is slidably sleeved inside the sliding groove. A crushing head is fixedly connected to one end of the sliding block. Multiple sets of crushing heads are rotatably sleeved at equal intervals on the inner wall of the crushing chamber.

[0007] Preferably, both ends of the fixed sleeve are fitted with abutment rings, and the inner walls of the two abutment rings are fixedly connected with abutment blocks. The abutment blocks are fixedly fitted inside the sliding groove of the fixed sleeve near both ends, and fasteners are fixedly fitted inside the fixed sleeve and the two abutment rings.

[0008] Preferably, the oscillating assembly includes connectors, the upper ends of which are fixedly installed at the bottom of the screening screen plate near both ends, the lower ends of which are fixedly connected to connecting guide posts, the lower ends of which are fixedly installed with movable plates, and the lower ends of which are fixedly installed with compression springs.

[0009] Preferably, each of the compression springs has a telescopic cylinder fixedly installed at its lower end, and the compression springs are located on the inner wall of the telescopic cylinder. The inner wall of each of the telescopic cylinders is slidably fitted with a movable piece, and the lower end of each of the telescopic cylinders is fixedly installed with a crossbeam rod, with two crossbeam rods located at the bottom of the screening screen plate near both ends.

[0010] Preferably, guide blocks are fixedly connected to both ends of the two crossbeams, a telescopic rod is fixedly installed at the lower end of one of the crossbeams, a first bearing plate is slidably sleeved on the outer side of the upper end of the telescopic rod, guide plates are fixedly installed at both ends of the top of the first bearing plate, guide grooves are opened inside the four guide plates, limit blocks are fixedly installed at the upper end of the four guide plates, and guide blocks are slidably connected inside the guide grooves, and one end of the first bearing plate is fixedly connected to both ends of the crossbeam.

[0012] The beneficial effects of this utility model are: 1. This utility model utilizes a swing assembly. Through the reciprocating motion of a telescopic hydraulic cylinder and a telescopic rod, multiple telescopic cylinders and movable plates swing up and down inside the assembly, creating a certain oscillation. This keeps the pores of the crushing chamber of the screening screen dynamic, preventing coarse particles of ductile iron spheroidizing agent from being retained in the screen pores. The coarse particles of ductile iron spheroidizing agent remaining at the top are fed into the crushing chamber, continuously crushing them. This avoids substandard coarse particles clogging the pores of the screening screen, reducing the likelihood that subsequent crushed spheroidizing agent particles cannot pass through the screening screen smoothly, thus affecting the overall screening efficiency and finished product separation effect.

[0013] 2. This utility model features a detachable crushing cutter head structure. When the cutter head is worn and needs to be replaced, simply remove the fasteners, take off the retaining ring, and remove the worn crushing cutter head from the sliding groove of the fixed sleeve, thereby avoiding a reduction in the crushing effect of the ductile iron spheroidizing agent.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please refer to Figure 1 and Figure 2 As shown, an alloy pelletizer for producing ductile iron spheroidizing agents includes a workbench 1, a crushing chamber 2 fixedly installed at the upper end of the workbench 1, a feed hopper 3 fixedly connected to the upper part of the outer wall of the crushing chamber 2, side plates 4 fixedly installed at both ends of the crushing chamber 2, a screening screen 6 slidably sleeved on the lower part of the inner wall of the crushing chamber 2, and a swinging component 5 for swinging and cleaning the screen holes of the screening screen 6 is provided on one side of the inner wall of the workbench 1.

[0018] Please refer to Figures 2 to 4 As shown, as a technical optimization of this utility model, a servo motor 21 is fixedly installed at one end of one side plate 4. The output shaft of the servo motor 21 is connected to a rotating rod 22. The rotating rod 22 is rotatably sleeved inside the side plate 4. Multiple sets of fixed sleeves 24 are fixedly sleeved at equal intervals on the outer side of the rotating rod 22. Sliding grooves 25 are opened inside the outer walls of the multiple sets of fixed sleeves 24. Sliding blocks 26 are slidably sleeved inside the sliding grooves 25. A crushing head 23 is fixedly connected to one end of the sliding block 26. Multiple sets of crushing heads 23 are rotatably sleeved at equal intervals on the inner wall of the crushing chamber 2. A stop ring 27 is sleeved at both ends of the fixed sleeve 24. A stop block 28 is fixedly connected to the inner wall of the two stop rings 27. The stop block 28 is fixedly sleeved inside the sliding grooves 25 of the fixed sleeve 24 near both ends. Fasteners 29 are fixedly sleeved inside the fixed sleeve 24 and the two stop rings 27.

[0019] In a specific embodiment, when the ductile iron spheroidizing agent in block or strip shape enters the crushing chamber 2 from the feed hopper 3, the servo motor 21 drives the rotating rod 22 to rotate inside the crushing chamber 2, thereby driving multiple sets of crushing cutter heads 23 to rotate. The ductile iron spheroidizing agent is squeezed, impacted, and sheared by the crushing cutter heads 23 against the inner wall of the crushing chamber 2, thereby crushing the ductile iron spheroidizing agent into particles. When the crushing cutter heads 23 need to be replaced periodically, the fasteners 29 are removed and pulled out from inside the two retaining rings 27 and the fixing sleeve 24. Then, the two retaining rings 27 are removed from both ends of the fixing sleeve 24, thereby moving multiple crushing cutter heads 23 out from inside the sliding groove 25 of the fixing sleeve 24.

[0020] Please refer to Figure 1 and Figure 2 , Figure 5 and Figure 6 As shown, as a technical optimization of this utility model, the swing assembly 5 includes connecting parts 51. The upper ends of the connecting parts 51 are fixedly installed at the bottom of the screening screen plate 6 near both ends. The lower ends of the two connecting parts 51 are fixedly connected to connecting guide posts 52. The lower ends of the multiple connecting guide posts 52 are fixedly installed with movable pieces 57. The lower ends of the multiple movable pieces 57 are fixedly installed with compression springs 56. The lower ends of the multiple compression springs 56 are fixedly installed with telescopic cylinders 58. The multiple compression springs 56 are all located on the inner wall of the telescopic cylinders 58. The inner walls of the multiple telescopic cylinders 58 are slidably fitted with movable pieces 57. The lower ends of the multiple telescopic cylinders 58 are fixedly installed with crossbeams 510. The two crossbeams 510 are respectively located at the bottom of the screening screen plate 6 near both ends.

[0021] Furthermore, guide blocks 59 are fixedly connected to both ends of the two crossbeams 510. A telescopic rod 511 is fixedly installed at the lower end of one of the crossbeams 510. A first bearing plate 55 is slidably sleeved on the outer side of the upper end of the telescopic rod 511. Guide plates 53 are fixedly installed at both ends of the top of the first bearing plate 55. Guide grooves are opened inside the four guide plates 53. Limiting blocks 54 are fixedly installed at the upper end of the four guide plates 53, and guide blocks 59 are slidably connected inside the guide grooves. One end of the first bearing plate 55 is fixedly connected to both ends of the crossbeam 510.

[0022] Furthermore, both first bearing plates 55 are fixedly sleeved on the inner wall of the workbench 1 near both sides. The lower end of the telescopic rod 511 is slidably sleeved with a telescopic hydraulic cylinder 512. The lower end of the telescopic hydraulic cylinder 512 is fixedly installed with a second bearing plate 513. The second bearing plate 513 is fixedly sleeved on one side of the inner wall of the workbench 1 near the bottom.

[0023] In a specific embodiment, to prevent coarse particles of ductile iron spheroidizing agent from appearing inside the pores of the screening mesh, the telescopic hydraulic cylinder 512 drives the telescopic rod 511 to move back and forth vertically. The telescopic rod 511 moves up and down inside the first bearing plate 55, further driving 510 to move back and forth at a specified interval, thereby driving multiple telescopic cylinders 58 to move up and down. The interior 56 of the multiple telescopic cylinders 58 elastically swings up and down, further driving multiple movable pieces 57 to move inside the telescopic cylinders 58, thereby driving the connecting guide post 52 and the connecting piece 51 to move back and forth. The crossbeam rod descends with the telescopic rod 511, and the compression spring resets under the action of gravity. One end of the screening mesh crushing chamber 2 falls down, generating up and down swinging movement. The guide block 59 slides down in the guide groove. When 6 swings up and down, the coarse particles of ductile iron spheroidizing agent remaining above 6 are sent into the crushing chamber 2, continuously crushing the coarse particles of ductile iron spheroidizing agent that can pass through the pore diameter of the screening mesh crushing chamber 2.

[0024] In use, when the ductile iron spheroidizing agent in block or strip form enters the crushing chamber 2 from the feed hopper 3, the servo motor 21 drives the rotating rod 22 to rotate inside the crushing chamber 2, which in turn drives multiple sets of crushing cutters 23 to rotate. The ductile iron spheroidizing agent is squeezed, impacted, and sheared by the crushing cutters 23 against the inner wall of the crushing chamber 2. To prevent coarse particles of ductile iron spheroidizing agent from appearing inside the pores of the screen, the telescopic hydraulic cylinder 512 drives the telescopic rod 511 to move back and forth vertically. The telescopic rod 511 moves up and down inside the first bearing plate 55, further driving the 510 to move back and forth at specified intervals. The movement causes multiple telescopic cylinders 58 to move up and down. The internal parts 56 of the multiple telescopic cylinders 58 elastically swing up and down, further causing multiple movable pieces 57 to move inside the telescopic cylinders 58. This causes the connecting guide post 52 and the connecting piece 51 to move up and down reciprocally. The crossbeam rod descends with the telescopic rod 511, and the compression spring resets under the action of gravity. One end of the screen plate crushing chamber 2 falls down, causing it to swing up and down. The guide block 59 slides down in the guide groove. When 6 swings up and down, the coarse particles of ductile iron spheroidizing agent stored above 6 are sent into the crushing chamber 2, continuously crushing the coarse particles of ductile iron spheroidizing agent that can pass through the pore diameter of the screen plate crushing chamber 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
