Description

Technical Field

[0001] The invention belongs to the technical field of spheroidizing agent production equipment, and specifically refers to a crushing device for spheroidizing agent production. Background Art

[0002] Spheroidizers are certain metals or alloys added to molten iron to obtain spheroidal graphite cast iron. The main function of spheroidizers is to promote the nucleation and growth of graphite, so that the graphite in cast iron crystallizes into spheres, thereby significantly improving the strength, toughness and other advantages of cast iron. The raw materials for the production of spheroidizers include ferrosilicon, magnesium powder, rare earth elements, and auxiliary materials such as lime, limestone, and calcium. When processing lime, limestone, and calcium, the raw materials need to be crushed. After the spheroidizer is produced, the spheroidizer also needs to be crushed into small pieces of different specifications to improve the mixing uniformity when the spheroidizer is added.

[0003] At present, in order to reduce the powder rate, the spheroidizer crushing device often uses a double-roll crusher to crush the spheroidizer. However, when crushing a larger spheroidizer, the toothed roller cannot crush it quickly, causing the raw material to be stuck between the two toothed rollers. The friction time between the two toothed rollers and the raw material is long, which leads to an increase in the powder rate of the raw material. Summary of the invention

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0034] like Figure 1 As shown, the present invention proposes a crushing device for spheroidizing agent production, including a casing 1, a first crushing roller 2, a second crushing roller 3 and a driving component, the first crushing roller 2 and the second crushing roller 3 are arranged parallel to each other inside the casing 1, and the driving component is arranged on one side of the casing 1.

[0035] The driving component is provided with two output ends. The first crushing roller 2 and the second crushing roller 3 are respectively connected to the two output ends of the driving component through a coupling. The driving component drives the first crushing roller 2 and the second crushing roller 3 to rotate respectively, and the first crushing roller 2 and the second crushing roller 3 rotate in opposite directions (such as Figure 6 As shown in the figure), it can squeeze and crush the materials thrown in from above.

[0036] In an optional embodiment, the crushing teeth on the first crushing roller 2 and the second crushing roller 3 are both long strip crushing teeth, which can crush the material more evenly and effectively control the crushing particle size.

[0037] In a specific embodiment, the driving component includes a reducer 7 and a motor 8, the output end of the motor 8 is connected to the input end of the reducer 7, the reducer 7 is provided with two output ends, the first crushing roller 2 and the second crushing roller 3 are respectively connected to the two output ends of the reducer 7 through a coupling, and the reducer 7 reduces the speed and increases the torque of the motor 8, thereby driving the first crushing roller 2 and the second crushing roller 3 to rotate.

[0038] Combination Figure 3 , Figure 4 and Figure 5 As shown, the second crushing roller 3 is provided with a plurality of second annular grooves 301 uniformly distributed along the axial direction, and two symmetrically arranged crushing arms 4 are provided in each of the second annular grooves 301. The crushing arms 4 are configured to be able to slide along the radial direction of the second crushing roller 3, and the crushing arms 4 can be driven to rotate by the second crushing roller 3. When the crushing arms 4 slide outward to the outer surface protruding from the second crushing roller 3, as the second crushing roller 3 drives the crushing arms 4 to rotate, the crushing range of the crushing arms 4 is greater than the crushing range of the second crushing roller 3 (such as Figure 6 As shown in the figure), the larger material stuck between the first crushing roller 2 and the second crushing roller 3 can be struck and crushed, so that the larger material is crushed into smaller volume materials. The first crushing roller 2 and the second crushing roller 3 can crush them quickly, shortening the contact time between the material and the crushing roller caused by the stuck material, thereby reducing the powder rate of the material.

[0039] Furthermore, the crushing arm 4 is configured to be able to slide reciprocatingly and to be telescopic, and the crushing arm 4 can be completely retracted into the second annular groove 301. In actual use, the crushing arm 4 is reciprocated and retracted at a certain frequency. When the crushing arm 4 is retracted into the second annular groove 301, the crushing arm 4 will not block the falling of the material, and the material thrown in from above can be fed between the first crushing roller 2 and the second crushing roller 3. When the crushing arm 4 slides outward to the outer surface of the protruding second crushing roller 3, the crushing arm 4 can strike and crush the material between the first crushing roller 2 and the second crushing roller 3 from above.

[0040] When the crushing arm 4 is retracted, it can feed material between the first crushing roller 2 and the second crushing roller 3. When the crushing arm 4 is extended, the material between the first crushing roller 2 and the second crushing roller 3 is struck and crushed, and this process is repeated to continuously feed and crush the material.

[0041] Combination Figure 3 and Figure 6 As shown, the first crushing roller 2 is provided with a plurality of first annular grooves 201 distributed along the axial direction and corresponding to the second annular grooves 301 . When the crushing arm 4 is extended, the rotating crushing arm 4 can pass through the first annular grooves 201 to avoid interference and collision with the first crushing roller 2 .

[0042] Furthermore, the depth of the first annular groove 201 is greater than the maximum extension length of the crushing arm 4 . When the crushing arm 4 is extended outward to the maximum length, it can still pass through the first annular groove 201 without causing any collision.

[0043] Combination Figure 4 and Figure 5 As shown, a central shaft 5 is coaxially arranged inside the second crushing roller 3, and a plurality of conical columns 51 corresponding to the second annular groove 301 are coaxially arranged on the central shaft 5, and the conical columns 51 are rotatably connected to the central shaft 5, but the conical columns 51 are axially fixed to the central shaft 5, so that the conical columns 51 can move axially synchronously with the central shaft 5, and the conical columns 51 can rotate relatively on the central shaft 5 without driving the central shaft 5 to rotate;

[0044] Two symmetrical and inclined slide rails 52 are provided on the conical column 51. One end of the crushing arm 4 is connected to the slide rail 52, and the other end of the crushing arm 4 extends into the second annular groove 301. When the conical column 51 slides back and forth along the axial direction of the central axis 5, the slide rail 52 can pull the crushing arm 4 to slide back and forth along the radial direction of the second crushing roller 3.

[0045] Furthermore, a telescopic component 6 is provided on the side of the casing 1 away from the driving component. One end of the central axis 5 extends to the outside of the second crushing roller 3 and is connected to the output end of the telescopic component 6. The telescopic component 6 is configured to be able to drive the central axis 5 to reciprocate along its own axial direction, so that the conical column 51 slides back and forth along the axial direction of the central axis 5.

[0046] In a specific embodiment, the telescopic component 6 includes a hydraulic cylinder, which is fixed on a side of the casing 1 away from the driving component. The hydraulic cylinder is connected to an external hydraulic station through a pipeline, and the telescopic rod of the hydraulic cylinder is controlled to be telescopic by a control valve on the hydraulic station. One end of the central axis 5 is connected to the telescopic rod of the hydraulic cylinder.

[0047] Combination Figure 4 and Figure 5 As shown, a support shaft 53 is provided at one end of the central shaft 5 away from the telescopic component 6, and the central shaft 5 is supported by the support shaft 53 to improve the stability of the central shaft 5; an axial hole corresponding to the support shaft 53 is provided at one end of the central shaft 5 away from the telescopic component 6, and the depth of the axial hole is greater than the length of the support shaft 53; one end of the support shaft 53 is slidably inserted in the axial hole, and the other end of the support shaft 53 is coaxially fixed to the end face of the second crushing roller 3; when the central shaft 5 slides, the central shaft 5 slides along the support shaft 53, which satisfies the supporting function of the central shaft 5 without affecting the sliding of the central shaft 5.

[0048] Furthermore, the shaft holes on the end faces of the support shaft 53 and the center shaft 5 are both circular. When the second crushing roller 3 rotates, the support shaft 53 is driven to rotate, but the center shaft 5 is not driven to rotate.

[0049] Combination Figure 3 and Figure 4 As shown, the second crushing roller 3 is coaxially fixed with a shaft tube 31, and the second crushing roller 3 is rotatably connected to the casing 1 through the shaft tube 31. Since the shaft tube 31 is a tubular structure, the central axis 5 can extend from the shaft tube 31 to the outside of the casing 1 and be connected to the output end of the telescopic component 6.

[0050] Furthermore, the inner diameter of the shaft tube 31 is larger than the outer diameter of the central shaft 5 , and the central shaft 5 does not contact the inner wall of the shaft tube 31 . When the shaft tube 31 rotates, there is no contact or friction with the central shaft 5 .

[0051] Combination Figure 6 and Figure 7 As shown, the crushing arm 4 includes a telescopic arm 41 and a striking hammer 42 . The telescopic arm 41 is located in the second annular groove 301 , and the telescopic arm 41 penetrates the side wall of the second crushing roller 3 and can slide along the radial direction of the second crushing roller 3 .

[0052] In a specific embodiment, a hole corresponding to the telescopic arm 41 is opened on the side wall of the second crushing roller 3, and the telescopic arm 41 passes through the hole, so that the telescopic arm 41 can slide along the radial direction of the second crushing roller 3 and can rotate synchronously with the second crushing roller 3;

[0053] One end of the telescopic arm 41 extends into the second crushing roller 3 and is connected to the slide rail 52. The striking hammer 42 is connected to the other end of the telescopic arm 41. Since the slide rail 52 is arranged inclined (such as Figure 7 As shown in the figure, when the conical column 51 slides back and forth along the axial direction of the central axis 5, the slide rail 52 can pull the telescopic arm 41 to slide back and forth along the radial direction of the second crushing roller 3, and the striking hammer 42 connected to the telescopic arm 41 slides and extends synchronously.

[0054] Furthermore, the striking hammer 42 is connected to the telescopic arm 41 through a rotating shaft, and the rotating shaft is parallel to the axis of the second crushing roller 3, so that the striking hammer 42 can rotate along the rotating shaft, and the rotation direction is perpendicular to the axis of the second crushing roller 3. When the striking hammer 42 strikes the material, the speed will decrease. Therefore, when the striking hammer 42 strikes the material, it can swing in the opposite direction to avoid the striking hammer 42 causing a large rotational load on the second crushing roller 3. After the striking hammer 42 passes through the material, under the action of centrifugal force, the striking hammer 42 rotates again to be parallel to the telescopic arm 41, and can strike and crush the material again.

[0055] It should be understood that when the telescopic arm 41 is at the maximum extension length, the telescopic arm 41 still does not protrude from the outer surface of the second crushing roller 3, so as to avoid the telescopic arm 41 from contacting the material. The material is only contacted by the striking hammer 42 to strike and crush the material.

[0056] Furthermore, the thickness of the telescopic arm 41 and the striking hammer 42 are both smaller than the width of the second annular groove 301 and the first annular groove 201, so that the telescopic arm 41 and the striking hammer 42 can be completely retracted into the second annular groove 301, and when in the extended state, can smoothly pass through the first annular groove 201 of the first crushing roller 2 to avoid mutual interference.

[0057] Combination Figure 7 As shown, two symmetrically arranged slide grooves 501 are provided on the conical column 51, and the slide rail 52 is fixed in the slide groove 501, so that the slide rail 52 can be hidden inside the slide groove 501 and will not occupy the internal space of the second crushing roller 3. The setting depth of the second annular groove 301 can be increased to provide sufficient storage space for the striking hammer 42. Accordingly, the striking hammer 42 can be set to a larger length to increase the striking range of the striking hammer 42.

[0058] Combination Figure 3 and Figure 4 As shown, the spacing distance between the plurality of second annular grooves 301 is 10.0-15.0 cm, preferably 10.0 cm. Correspondingly, the spacing distance between the crushing arms 4 is 10.0 cm. A smaller spacing distance can increase the number of crushing arms 4 and improve the crushing uniformity of the material.

[0059] The working principle of the present invention is as follows: after the motor 8 is decelerated and torqued by the reducer 7, the first crushing roller 2 and the second crushing roller 3 are driven to rotate, and the first crushing roller 2 and the second crushing roller 3 rotate in opposite directions (such as Figure 6 As shown in the figure, the material thrown in from above can be squeezed downward and crushed. During the crushing process, the telescopic component 6 drives the central shaft 5 to reciprocate at a certain frequency, so that the slide rail 52 on the conical column 51 can pull the crushing arm 4 to slide and reciprocate at a certain frequency. When the crushing arm 4 is extended, the crushing range of the crushing arm 4 is larger than the crushing range of the second crushing roller 3 (as shown in the figure). Figure 6 As shown in the figure), the larger material stuck between the first crushing roller 2 and the second crushing roller 3 can be struck and crushed, so that the larger material is crushed into smaller volume materials. The first crushing roller 2 and the second crushing roller 3 can crush it quickly, shortening the contact time between the material and the crushing roller caused by the stuck material, thereby reducing the powder rate of the material. When the crushing arm 4 contracts, it can feed the material between the first crushing roller 2 and the second crushing roller 3, and so on, continuously feeding and crushing the material.

[0060] In summary of the above embodiments: by arranging a crushing arm 4 with a larger crushing range on one side of the crushing roller, and arranging the crushing roller on the other side to avoid the first annular groove 201 for the crushing arm 4, the crushing arm 4 can strike and crush the larger material stuck between the first crushing roller 2 and the second crushing roller 3, so that the larger material is crushed into smaller volume materials, and the first crushing roller 2 and the second crushing roller 3 can crush them quickly, shortening the contact time between the material and the crushing roller caused by the stuck material, thereby reducing the powder rate of the material;

[0061] By setting the crushing arm 4 to be telescopic, and using the telescopic component 6 to drive the crushing arm 4 to telescope at a certain frequency, when the crushing arm 4 contracts, it can feed the material between the first crushing roller 2 and the second crushing roller 3 to avoid the crushing arm 4 blocking the input of the material. When the crushing arm 4 is extended, the material between the first crushing roller 2 and the second crushing roller 3 is struck and crushed, and this reciprocating process is continued to feed and crush the material.

[0062] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0063] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
