Description

Technical Field

[0001] The invention relates to the field of waste slag treatment, and in particular to a metal waste slag crushing treatment device. Background Art

[0002] In the field of metal waste slag treatment, with the rapid development of industry, the production, processing and consumption of metal products continue to rise, and the amount of metal waste slag generated is also increasing. These metal waste slags come from a wide range of sources, including slag in the metal smelting process, scraps from metal processing and manufacturing, and residuals from the recycling of scrap metal products such as scrapped cars and discarded electrical equipment. Traditional methods of metal waste slag treatment have gradually exposed many limitations in the face of increasingly complex and large amounts of metal waste slag.

[0003] In the early days, metal waste was mostly treated by a combination of simple manual sorting and preliminary crushing tools. Manual sorting is inefficient and labor-intensive, making it difficult to meet large-scale processing needs. Traditional crushing tools, such as single-axis crushers, often suffer from incomplete crushing and easy jamming when dealing with metal waste, especially when dealing with metal waste of irregular shapes, large volumes, and large hardness differences. For example, when dealing with scrap car frames, a single-axis crusher may not be able to effectively grab and tear off various parts of the waste, resulting in poor crushing results. Multiple repeated crushing operations are required, greatly reducing processing efficiency.

[0004] At the same time, with the continuous improvement of environmental protection requirements, the recycling rate of metal waste has become an important consideration. Traditional crushing methods are difficult to crush metal waste to an ideal particle size range, which is not conducive to the efficient separation and recovery of subsequent metal components. In addition, some metal waste may be mixed with other impurities or metals of different materials. Traditional crushing equipment is difficult to achieve preliminary separation and dispersion of mixed materials during the crushing process, which increases the complexity and cost of subsequent processing procedures.

[0005] In this context, the double-shaft shredder came into being. With its unique double-shaft structure design, the double-shaft shredder can cooperate with different types of cutters installed on the two shafts to crush metal waste slag at multiple angles and in multiple ways. Its double shafts rotating in opposite directions can effectively grab and tear metal waste slag of various shapes and sizes, whether it is a large piece of metal sheet or a complex metal component, it can be crushed more thoroughly. Moreover, the tool configuration of the double-shaft shredder is flexible and can be adjusted according to the specific characteristics of the metal waste slag. For example, special carbide cutters are used for high-hardness metal waste slag, and suitable shear cutter combinations are selected for tough metals, thereby improving the adaptability and crushing effect of different metal waste slag. Furthermore, the double-shaft shredder can achieve a certain degree of material mixing and preliminary separation through reasonable chassis design and internal structure optimization during the crushing process, reducing the difficulty and cost of subsequent processing procedures, providing strong technical support for the efficient recycling of metal waste slag, and gradually becoming one of the important equipment in the field of metal waste slag crushing and processing.

[0006] In the prior art, a Chinese patent with the announcement number CN117983380B discloses a metal cutting and crushing device, which uses an auxiliary structure to pre-shred the metal waste slag agglomerates and then crush them. However, due to the different production environments of the current metal waste slag, when it is crushed, it will get stuck because of the toughness of the metal characteristics or the inclusion of lumps such as welding slag, which affects the processing effect. Summary of the invention

[0007] The invention provides a metal waste slag crushing processing device to solve the technical problems of blade jamming and unsatisfactory crushing of the tough slag due to the mixing of tough slag and rigid slag in the process of crushing the metal waste slag.

[0008] A metal waste slag crushing and processing device of the present invention adopts the following technical scheme: it includes a support mechanism for providing support and a power mechanism for providing power, the power mechanism is installed on the side of the support mechanism, a discharging mechanism is installed at the bottom of the support mechanism, and also includes a crushing mechanism for crushing the waste slag, a cutter head mechanism and a tension adjustment mechanism for adjusting the crushing state of the cutter head mechanism, the crushing mechanism includes a rotating cutter disc and a matching block, the power mechanism is provided with two main shafts, and the rotating cutter disc and the matching block are staggered between the two main shafts, a side support block is provided on the matching block away from the rotating cutter disc, a plurality of cutter head mechanisms are evenly arranged on the outer circumferential surface of the rotating cutter disc, the cutter head mechanism includes a crushing cutter head, the crushing cutter head is rotatably connected to the rotating cutter disc, and the main shaft is connected to the power member through an axial adjustment mechanism;

[0009] The crushing cutter head is divided into a crushing end and an adjusting end. The crushing cutter head adjusting end is connected to the rotating cutter disc through a buffer adjusting component, and the crushing cutter head adjusting end is a semicircular structure. The buffer adjusting component corresponds to the side of the axial adjusting mechanism and cooperates with the tension adjusting mechanism. When the axial adjusting mechanism drives the main shaft to move axially, the main shaft applies pressure to the buffer adjusting component through the tension adjusting mechanism, thereby adjusting the crushing state of the crushing cutter head.

[0010] In this example, the buffer adjustment assembly includes a connecting rod, a buffer groove, and a connected head. The buffer groove is a cylindrical through groove. The adjustment end of the crushing cutter head and the part of the connecting rod corresponding to the rotating cutter disc are both formed with the buffer groove and correspond in the initial position. The diameter of the connecting rod is smaller than the diameter of the buffer groove. The two ends of the connecting rod are respectively fixed with a connected head. The crushing cutter head is formed with a connecting groove at the position of the connected head. The end of the connecting rod away from the crushing cutter head passes through the buffer groove of the rotating cutter disc. The connected head on the connecting rod corresponding to the end of the rotating cutter disc corresponds to the tension adjustment mechanism. An elastic reset part is provided on the outside of the connecting rod and located in the buffer groove.

[0011] In this example, eight rotating cutter discs are provided.

[0012] In this example, the tension adjustment mechanism includes an extrusion seat, which is slidably connected to the rotating cutter disc. The extrusion seat is formed with 8 extrusion grooves corresponding to the end face of the connecting rod. The extrusion grooves are trapezoidal grooves and have a wide surface corresponding to one end of the connecting rod. The narrowest parts of the two extrusion grooves are smaller than the diameter of the connected head.

[0013] In this example, a fixed seat is formed on the end surface of the extrusion seat away from the rotating cutter disc, the fixed seat is fixedly connected to the main shaft, and the rotating cutter disc is slidably connected to the main shaft via a spline.

[0014] In this example, when the rotating cutter disc and the extrusion seat are in the initial positions, the widest part of the extrusion groove is larger than the diameter of the one-piece head.

[0015] In this example, the diameter of the buffer groove is three times the diameter of the connecting rod, and the size of the joint head is twice the diameter of the connecting rod.

[0016] In this example, the rotation angle of the crushing cutter head is 0°-10°.

[0017] In this example, the axial adjustment mechanism includes an extrusion sleeve, an extrusion connecting seat, and a reset piece. One end of the extrusion sleeve is connected to the connecting piece and the other end cooperates with the extrusion connecting seat. The extrusion connecting seat is fixedly connected to the main shaft at one end away from the extrusion sleeve, and the main shaft is connected to the reset piece at one end away from the extrusion connecting seat. The extrusion connecting seat is a cylinder with a plurality of spiral extrusion strips on the outside, and a spiral groove that cooperates with the spiral extrusion strip is formed inside the extrusion connecting seat. The direction of the spiral extrusion strip of the extrusion connecting seat and the direction of the spiral groove of the reset piece are both the rotational extrusion and crushing direction of the rotating cutter disc.

[0018] In this example, the reset member includes a sliding rod and a supporting spring. The sliding rod is slidably connected to the main shaft. A groove matching the sliding rod is formed on the main shaft.

[0019] The beneficial effects of the present invention are as follows: the present invention adjusts the state of the crushing cutter head through the cooperation of the axial adjustment mechanism and the tension adjustment mechanism. When facing tough metal waste slag, the waste slag can be torn and crushed through the multi-state and mutually staggered crushing cutter heads. When facing harder waste slag, the instantaneous clamping force is used to drive the axial displacement of the main shaft, thereby utilizing the instantaneous locking and transmission force to crush the waste slag, thereby improving the effect of waste slag treatment.

DETAILED DESCRIPTION

[0031] 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.

[0032] An embodiment of a metal waste slag crushing and processing device of the present invention is as follows Figures 1 to 9 As shown, it includes a support mechanism 1 for providing support and a power mechanism 2 for providing power, the power mechanism 2 is installed on the side of the support mechanism 1, and a discharging mechanism 4 is installed at the bottom of the support mechanism 1. It also includes a crushing mechanism 3 for crushing waste slag, a cutter head mechanism 5 and a tension adjustment mechanism 7 for adjusting the crushing state of the cutter head mechanism 5. The crushing mechanism 3 includes a rotating cutter disc 31 and a matching block 32. There are two main shafts 21 of the power mechanism 2, and the rotating cutter discs 31 and the matching blocks 32 are staggered between the two main shafts 21. A side support block 33 is arranged on the side of the matching block 32 away from the rotating cutter disc 31. A plurality of cutter head mechanisms 5 are evenly arranged on the outer circumferential surface of the rotating cutter disc 31. The cutter head mechanism 5 includes a crushing cutter head 51, which is rotatably connected to the rotating cutter disc 31. The main shaft 21 is connected to the power member through an axial adjustment mechanism 6.

[0033] The crushing cutter head 51 is divided into a crushing end and an adjusting end. The adjusting end of the crushing cutter head 51 is connected to the rotating cutter disc 31 through a buffer adjustment component, and the adjusting end of the crushing cutter head 51 is a semicircular structure. The buffer adjustment component corresponds to the side of the axial adjustment mechanism 6 and cooperates with the tension adjustment mechanism 7. When the axial adjustment mechanism 6 drives the main shaft 21 to move axially, the main shaft 21 applies pressure to the buffer adjustment component through the tension adjustment mechanism 7, thereby adjusting the crushing state of the crushing cutter head 51.

[0034] In this case, if Figure 7 As shown, the buffer adjustment assembly includes a connecting rod 52, a buffer groove 53, and a connected head 54. The buffer groove 53 is a cylindrical through groove. The adjustment end of the crushing cutter head 51 and the part of the connecting rod 52 corresponding to the rotating cutter disc 31 are both formed with a buffer groove 53 and correspond in the initial position. The diameter of the connecting rod 52 is smaller than the diameter of the buffer groove 53. The two ends of the connecting rod 52 are respectively fixed with a connected head 54. The crushing cutter head 51 is formed with a connecting groove 55 at the position corresponding to the connected head 54. The end of the connecting rod 52 away from the crushing cutter head 51 passes through the buffer groove 53 of the rotating cutter disc 31. The connected head 54 on the connecting rod 52 corresponding to the end of the rotating cutter disc 31 corresponds to the tension adjustment mechanism 7. An elastic reset member is provided on the outside of the connecting rod 52 and located in the buffer groove 53.

[0035] In this example, if Figure 6 As shown, eight rotating cutter discs 31 are provided.

[0036] In this example, if Figure 4-Figure 8 As shown, the tension adjustment mechanism 7 includes an extrusion seat 72, which is slidably connected to the rotating cutter disc 31. The extrusion seat 72 is formed with 8 extrusion grooves 73 on the end surface of the connecting rod 52 corresponding to the extrusion seat 72. The extrusion grooves 73 are trapezoidal grooves, and one end of the corresponding connecting rod 52 is a wide surface. The narrowest part of the two extrusion grooves 73 is smaller than the diameter of the conjoined head 54. When in the initial state, the rotating cutter disc 31 and the extrusion grooves 73 on the extrusion seat 72 do not clamp the conjoined head 54. At this time, the crushing cutter head 51 is supported by the external spring of the connecting rod 52, and because the rotating cutter disc 31 is provided with an external spring There are 8 crushing heads 51 with a pressure regulating mechanism. Each crushing head 51 has a different state when applying pressure to crush the waste slag, and the crushing heads 51 on the staggered rotating cutter disc 31 also have different states. At this time, the crushing head 51 will reach the rotation limit after rotation. The staggered crushing heads 51 reach the rotation limit at different times, thereby producing an effect of squeezing, cutting and tearing the residue, thereby effectively crushing the waste slag. At the same time, it can also cope with waste slag with greater toughness, using two-way toughness to offset tearing, thereby improving the crushing effect.

[0037] In this example, a fixed seat 71 is formed on the end face of the extrusion seat 72 away from the rotating cutter disc 31. The fixed seat 71 is fixedly connected to the main shaft 21. The rotating cutter disc 31 is slidably connected to the main shaft 21 via a spline. Because the rotating cutter discs 31 on the two main shafts 21 are staggered and mating blocks 32 are provided between them, the sliding clearance of the rotating cutter discs 31 is small. Since the fixed seat 71 is fixedly connected to the main shaft 21, when the main shaft 21 moves axially, the fixed seat 71 can be driven to move axially in time.

[0038] In this example, when the rotating cutter disc 31 and the extrusion seat 72 are in the initial position, the widest part of the extrusion groove 73 is larger than the diameter of the joint head 54 .

[0039] In this example, the diameter of the buffer groove 53 is three times the diameter of the connecting rod 52 , and the size of the joint head 54 is twice the diameter of the connecting rod 52 .

[0040] In this example, the rotation angle of the crushing cutter head 51 is 0°-10°.

[0041] In this example, the axial adjustment mechanism 6 includes an extrusion sleeve 61, an extrusion connecting seat 62, and a reset piece 63. One end of the extrusion sleeve 61 is connected to the extrusion connecting seat 62, and the other end is matched with the extrusion connecting seat 62. The end of the extrusion connecting seat 62 away from the extrusion sleeve 61 is fixedly connected to the main shaft 21, and the end of the main shaft 21 away from the extrusion connecting seat 62 is connected to the reset piece 63. The extrusion connecting seat 62 is a cylinder with a plurality of spiral extrusion strips on the outside. The extrusion connecting seat 62 is internally formed with a spiral groove that matches the spiral extrusion strip. The direction of the spiral extrusion strip of the extrusion connecting seat 62 and the direction of the spiral groove of the reset piece 63 are both the rotational extrusion and crushing direction of the rotating cutter disc 31.

[0042] In this example, the reset member 63 includes a slide bar and a support spring. The slide bar is slidably connected to the main shaft 21 , and a groove matching the slide bar is formed on the main shaft 21 .

[0043] The working principle is as follows: the motor of the power mechanism 2 is started, and the main shaft 21 is driven to rotate through the cooperation of the extrusion sleeve 61 and the extrusion connection seat 62, and at this time, the main shaft 21 drives the rotating cutter head 31 to rotate idly;

[0044] When the waste residue passes through the opening of the support mechanism 1 and reaches the upper side of the rotating cutter disc 31, the waste residue is subjected to the destructive force of the staggered rotating cutter disc 31. At this time, the rotating cutter disc 31 transmits the reverse torque to the extrusion connection seat 62 and the extrusion sleeve 61 through the main shaft 21. At this time, the spiral extrusion strips and spiral grooves between the extrusion sleeve 61 and the extrusion connection seat 62 are staggered, and the extrusion connection seat 62 is extruded from the inside of the extrusion sleeve 61. At this time, the main shaft 21 and the fixed seat 71 drive the axial displacement;

[0045] In this state, the fixed seat 71, the extrusion seat 72, and the extrusion groove 73 move toward the rotating cutter disc 31, and because the crushing cutter head 51 crushes the waste, the crushing cutter head 51 begins to rotate relative to the rotating cutter disc 31. Because each crushing cutter head 51 is independent, the crushing cutter head 51 drives the connecting rod 52 to move toward the rotating cutter disc 31 during rotation. At the same time, because the fixed seat 71 drives the extrusion seat 72 to approach the rotating cutter disc 31, the two extrusion grooves 73 begin to close. However, because the toughness of the waste is not enough to completely turn the crushing cutter head 51 over, and the reset member 63 cannot be completely squeezed, the crushing cutter head 51 rotates relative to the rotating cutter disc 31 at this time. The degree of rotation of each crushing cutter head 51 is different, so the staggered crushing cutter heads 51 tear and crush the waste.

[0046] When there is a harder substance in the waste slag, the crushing blade 51 is in instant contact with the hard substance, and the crushing blade 51 and the rotating blade disc 31 are instantly clamped. Since the two extrusion grooves 73 are of a trapezoidal structure, even if the extrusion sleeve 61 is squeezed by the extrusion connecting seat 62 to generate a force that instantly drives the main shaft 21 to move, the inclined surface inside the extrusion groove 73 cooperates with the joint head 54, and the instant clamping force causes the joint head 54 to provide an instant counter-impact to the crushing blade 51. If the waste slag is crushed by the instant counter-impact at this time, it is most appropriate. If it cannot be crushed instantly, the inclined surface of the extrusion groove 73 will continue to squeeze. The combined head 54 is pressed so that it resists between the turning force of the crushing cutter head 51 and the clamping force of the extrusion groove 73. At this time, the crushing cutter head 51 is simultaneously subjected to the revolution of the rotating cutter disc 31, its own rotation, and the force of the reverse inclined surface squeezing the combined head 54. The waste residue is squeezed and rubbed by the end surface under the action of multiple forces until the combined head 54 abuts against the tail of the extrusion groove 73. The extreme position of the bottom of the extrusion groove 73 again provides an instantaneous impact for the combined head 54, the connecting rod 52, and the crushing cutter head 51, thereby impacting the waste residue again until the waste residue is crushed for the second time, thereby ensuring the crushing of the waste residue.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
