Abstract
Description
Technical Field
[0001] This utility model relates to the field of material processing technology, and more specifically, to a material crushing device and a material crushing system. Background Technology
[0002] In the field of materials processing, some materials need to be processed by high-temperature firing in a kiln in a square crucible to form hard blocks, including graphite and hard carbon in negative electrode materials.
[0003] Taking negative electrode materials as an example, in the current production process of natural graphite, it is necessary to first mix the crushed and purified flake graphite with asphalt, place it in a square crucible and send it into the kiln. Due to the characteristics of the material itself, after high-temperature firing, the material in the square crucible will form hard blocks, which makes it impossible for the material to be vacuumed or poured out after 180° rotation.
[0004] Currently, there are two main methods for crushing and discharging agglomerated materials. One is the blade crushing method, which first uses an unlimited number of parallel horizontal blades to divide the agglomerated material into several rows, then uses an unlimited number of parallel vertical blades (perpendicular to the previous blades) to divide the agglomerated material into small square pieces, and finally uses a third crushing blade that overlaps with the center of the small square pieces to complete the crushing of the material. Then, the material is discharged through vacuum suction or 180° rotation in the next process. The other is the circular shield crushing method, which first uses a circular shield machine to crush the cylindrical material in the square crucible while simultaneously vacuum-suctioning the material through the vacuum suction hole in the center of the circular shield machine. Then, a four-corner blade crushes the material remaining in the four corners of the square crucible, and then the material is discharged through vacuum suction in the next process.
[0005] However, when crushing high-hardness materials, the blade crusher is prone to crushing crucibles that are not hard enough, or the materials may not be crushed at all, because the force on the crucible and the material is in the vertical direction. The circular shield crusher can only crush materials within a cylindrical shape and cannot crush the material remaining in the four corners of a square crucible. It still requires a blade crushing process, which leads to high equipment costs and still carries the risk of crucible breakage, resulting in high crucible consumption costs.
[0006] As can be seen from the above, the existing technology has the problem of poor crushing effect on agglomerated materials. Utility Model Content

[0009] Furthermore, the periphery of the bottom opening of the outer shell is serrated.

[0015] Furthermore, the crushing component has a discharge hole that runs through the top and bottom, which allows the crushed material to enter the screw conveyor after crushing.
[0016] Furthermore, the material crushing device also includes a second driving component, which is mounted on the support and is connected to the crushing mechanism for driving the crushing mechanism to lift and lower.

Detailed Implementation
[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0034] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0035] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.
[0036] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0037] To address the problem of poor crushing effect of agglomerated materials in existing technologies, this utility model provides a material crushing device and a material crushing system.
[0038] like Figures 1 to 5 As shown, the material crushing device includes a base 10, a support 20, and a crushing mechanism 30. The support 20 is erected on the base 10. The crushing mechanism 30 is vertically connected to the support 20. The crushing mechanism 30 includes a housing 31 and a crushing component 32. The housing 31 has a bottom opening and a receiving cavity communicating with the bottom opening. The crushing component 32 is rotatably disposed within the receiving cavity. The cross-section of the housing 31 is a rounded square, and the crushing component 32 is a Reichol triangle adapted to the rounded square. The crushing mechanism 30 is used to crush the material to be crushed.
[0039] This application sets the outer shell 31 of the crushing mechanism 30 to a rounded square that fits the inner cavity of the container 1000, and sets the crushing component 32 to a Reichstag triangle that fits the rounded square. This makes the movement coverage area of the crushing component 32 during rotation a rounded square, and achieves the crushing shape of the crushing component 32 as a rounded square. This allows the material to be crushed in the container 1000 to be completely crushed in one go without secondary processing in other processes, greatly reducing the crushing steps, improving the crushing effect on agglomerated materials, and reducing production costs.
[0040] In this embodiment, as Figure 1 As shown, the material to be crushed is placed inside the container 1000 of the material crushing system. During crushing, the container 1000 is located between the crushing mechanism 30 and the base 10, with the crushing mechanism 30 extending into the container 1000 to crush the material. Furthermore, the inner cavity shape of the container 1000 is adapted to the outer shell 31. By setting the outer shell 31 of the crushing mechanism 30 as a rounded square adapted to the inner cavity of the container 1000, the material to be crushed can be more thoroughly and completely pulverized in one pass.
[0041] It should be noted that a rounded square is a square with rounded corners on all four sides.
[0042] In this embodiment, container 1000 is a square crucible. It can be understood that the cross-section of the inner cavity of container 1000 is also a rounded square.
[0043] In this embodiment, the periphery of the bottom opening of the outer shell 31 is serrated. It can be understood that the tips of the serrations are set downwards. Since the shape of the outer shell 31 is adapted to the inner cavity of the container 1000, when the outer shell 31 is inserted into the container 1000, the periphery of the serrations at the bottom of the outer shell 31 can crush the material to be crushed that is adhered to the four sides of the container 1000, so that all the material to be crushed is wrapped inside the outer shell 31, ensuring that the material to be crushed inside the container 1000 is crushed as much as possible.
[0044] like Figures 3 to 5 As shown, the crushing mechanism 30 also includes a first driving member 33 and an eccentric connecting member 34. The first driving member 33 is driven to the crushing member 32 through the eccentric connecting member 34, and is used to drive the crushing member 32 to rotate eccentrically. In this embodiment, due to the rounded square shape limitation of the outer shell 31 and the eccentric rotation of the crushing member 32 driven by the eccentric connecting member 34, the crushing member 32 can simultaneously rotate and deflect, achieving a crushed shape of a rounded square, thereby enabling the material to be crushed in the container 1000 to be completely crushed in one go.
[0045] In this embodiment, the eccentric connector 34 is a universal joint structure. By setting the eccentric connector 34 as a universal joint structure, the crushed part 32 can freely rotate and shift within the outer casing 31, achieving a crushed shape of a rounded square. Specifically, as shown... Figure 4 As shown, the eccentric connector 34 includes a coupling 341 and a universal joint 342. The coupling 341 is connected to the first driving component 33, and the universal joint 342 is universally connected to the crushing component 32. Further, the universal joint 342 includes a first section, a second section, and a third section that are sequentially hinged vertically. The coupling 341 is connected and fixed to the first driving component 33, and the first section is connected and fixed to the coupling 341 by bolts or other means. The third section is connected and fixed to the crushing component 32 by bolts or other means. Of course, the universal connection structure can also be other structural forms such as a universal ball joint, which can be selected according to actual needs.
[0046] In this embodiment, the fragment 32 is a Reuleaux triangle-shaped sheet structure. Specifically, as shown... Figure 11As shown, the Leroy triangle of broken component 32 refers to a curved triangle formed by connecting three arcs, each centered at one of the three vertices of an equilateral triangle and with its side length as the radius. A Leroy triangle has the same width in any direction, meaning it can rotate freely between two parallel lines at a distance equal to its arc radius (equal to the side length of the equilateral triangle) and always remain in contact with both lines. The method for drawing a Leroy triangle is as follows: a) First, draw an equilateral triangle with predetermined side lengths; b) Then, using the three side lengths as radii and the three vertices as centers, draw three circles with radii equal to the predetermined side lengths; c) Finally, take the arcs between the three vertices as the three arc sides of the Leroy triangle, thus completing the drawing of the Leroy triangle.
[0047] Furthermore, such as Figures 6 to 8 As shown, a first crushing part 321 is provided on the lower surface of the crushing component 32. The first crushing part 321 is located at the corner of the crushing component 32, extends along the rotation direction of the crushing component 32, and has a crushing blade at one end.
[0048] Furthermore, such as Figures 6 to 8 As shown, a second crushing part 322 is also provided on the lower surface of the crushing component 32. The second crushing part 322 protrudes downward from the lower surface of the crushing component 32 and has a pointed tip.
[0049] In this embodiment, the outer surface of the first crushing part 321 is adapted to the arc-shaped edge of the crusher 32, forming a triangular shape. The end facing the rotation direction of the crusher 32 is the tip with the crushing blade, achieving horizontal rotational cutting and compression crushing of the material to be crushed. Furthermore, the downward-protruding tip of the second crushing part 322 can both penetrate downward to crush the material to be crushed and cut and compress the material during rotation. Under the combined action of the two crushing parts, complete crushing of the material to be crushed is achieved. Of course, the first crushing part 321 and the second crushing part 322 can also be other shapes and structures, which can be selected according to actual needs.
[0050] It is understood that there are three first crushing parts 321, which are located at the three corners of the crusher 32 and extend along the rotation direction of the crusher 32. Furthermore, there are multiple second crushing parts 322, which are spaced apart on the lower surface of the crusher 32. Specifically, the multiple second crushing parts 322 are spaced apart along at least three arcuate edges of the crusher 32.
[0051] In this embodiment, as Figure 5As shown, the crushing component 32 is located at the bottom of the receiving cavity. A spiral hopper 35 is also provided above the crushing component 32 within the receiving cavity. The material to be crushed after crushing is discharged through the spiral hopper 35. Specifically, the spiral hopper 35 has a circumferential spiral discharge channel and a central through-hole extending vertically. An eccentric connector 34 passes through the central through-hole, thereby connecting the first drive component 33 and the crushing component 32. Furthermore, a through-hole is provided at the top of the outer shell 31, communicating with the spiral discharge channel of the spiral hopper 35. The material to be crushed after crushing flows out of the crushing mechanism 30 through the through-hole and then flows to the material receiving device 300 of the material crushing system.
[0052] Furthermore, such as Figure 6 and Figure 8 As shown, the crusher 32 has a through-hole 323 for allowing the crushed material to enter the screw conveyor 35. Specifically, there can be multiple discharge holes 323, which are evenly spaced along the circumference of the crusher 32. It can be understood that the discharge holes 323 are located between the outer periphery and the center of the crusher 32. This arrangement ensures that the crusher 32 can rotate evenly and stably, preventing it from tipping over.
[0053] In this embodiment, the discharge hole 323 is fan-shaped, and a connecting bridge is formed between two adjacent discharge holes 323. Multiple second crushing parts 322 are also spaced apart on the connecting bridge.
[0054] In this embodiment, as Figure 2 As shown, the material crushing device also includes a second driving component 40. The second driving component 40 is mounted on the support 20 and is drivenly connected to the crushing mechanism 30, used to drive the crushing mechanism 30 to lift and lower. Further, as... Figure 3 As shown, the crushing mechanism 30 also includes a mounting base 36, and the outer shell 31 and the first driving member 33 are both connected and fixed to the mounting base 36. The second driving member 40 is driven to the mounting base 36, thereby driving the entire crushing mechanism 30 to rise or fall.
[0055] like Figure 2 As shown, the material crushing device also includes a first foot cup 50. The first foot cup 50 is located at the bottom of the base 10. Specifically, there are four first foot cups 50, which are located at the four corners of the base 10, and their height is adjusted to provide stable support for the material crushing device.
[0056] In this embodiment, both the first driving component 33 and the second driving component 40 are electric motors. Of course, other mechanisms such as electric cylinders and motor screw lifting mechanisms can also be used, and the appropriate mechanism can be selected according to actual needs.
[0057] like Figure 1 , Figures 9 to 10As shown, this application also provides a material crushing system, including the aforementioned material crushing device 100, container 1000, conveying device 200, and receiving device 300. The container 1000 is used to hold the material to be crushed. The conveying device 200 is used to convey the container 1000 containing the material to be crushed to the space between the crushing mechanism 30 and the base 10, that is, below the crushing mechanism 30. The receiving device 300 is connected to the outer casing 31 and is used to collect the material to be crushed after the crushing process.
[0058] like Figure 9 As shown, the conveying device 200 includes a frame 210, second foot cups 220, and a conveying rail 230. The second foot cups 220 are located at the bottom of the frame 210. Specifically, there are four second foot cups 220, each located at one of the four corners of the frame 210, providing stable support for the conveying device 200 through height adjustment. The conveying rail 230 is mounted on the frame 210. Multiple conveying rollers 240 are spaced apart along the conveying direction on the conveying rail 230. The container 1000 is placed on the conveying rail 230 and conveyed to the area below the crushing mechanism 30 via the conveying rollers 240. It is understood that the conveying rail 230 is located below the crushing mechanism 30.
[0059] Furthermore, the conveying device 200 also includes two limiting baffles 250. The two limiting baffles 250 are located on both sides of the conveying rail 230 and extend along the conveying direction. The width of the container 1000 can be adjusted by adjusting the position of the limiting baffles 250.
[0060] Furthermore, the conveying device 200 also includes a position detection sensor 260 and a clamping member 270. When the position detection sensor 260 detects that the container 1000 is in position, the clamping member 270 clamps and fixes the container 1000.
[0061] In this embodiment, the position detection sensor 260 is a through-beam sensor, with its transmitting module and receiving module located on opposite sides of the conveyor rail 230. Of course, the position detection sensor 260 can also be other types of sensors, which can be selected according to actual needs.
[0062] In this embodiment, the clamping element 270 is a clamping cylinder. Specifically, there are four clamping elements 270, arranged in pairs on both sides of the conveyor rail 230, used to clamp and fix the four corners of the container 1000 respectively.
[0063] like Figure 10As shown, the receiving device 300 includes a suction pipe 310, a bin 320, and a support foot 330. The suction pipe 310 is connected to both the through hole in the outer casing 31 and the bin 320. The support foot 330 is used to support the bin 320. Furthermore, the bin 320 has a discharge port 340 at the bottom and an inspection port 360 at the top.
[0064] Furthermore, the receiving device 300 also includes a negative pressure air source 350. The negative pressure air source 350 generates a vacuum negative pressure, and the crushed material is sucked into the storage chamber 320 from the suction pipe 310 by the vacuum negative pressure. After the negative pressure air source 350 stops operating, the crushed material can be discharged from the discharge port 340. In this embodiment, the negative pressure air source 350 can be a Roots blower, a centrifugal blower, a negative pressure pump, etc.
[0065] Furthermore, the receiving device 300 can also be a dust collector, a vacuum feeder, a vacuum cleaner, etc.
[0066] The crushing process of the material crushing system in this application is as follows:
[0067] A container 1000 containing the material to be crushed runs on the conveyor rail 230, following the conveyor roller 240, and does not exceed the position beyond the limit baffle 250. When the position detection sensor 260 detects that the container 1000 is in position, the clamping member 270 clamps and fixes the container 1000. The second drive member 40 drives the crushing mechanism 30 to move downward and crush the material to be crushed in the container 1000. The serrated periphery of the outer shell 31 first crushes the material to be crushed that is adhered to the four sides of the container 1000, so that all the material to be crushed is enclosed in the outer shell 31. The first drive member 33 starts, and as the coupling 341, universal joint 342 and crushing member 32 are connected from top to bottom, the crushing member 32 is driven to rotate. Due to the rounded square shape of the outer shell 31 and the characteristics of the universal joint structure, the crusher 32 simultaneously rotates and deflects. The first crushing part 321 and the second crushing part 322 cut and crush the agglomerated material, resulting in a rounded square shape. This allows for the complete crushing of cubical materials in the container 1000 in a single operation. The crushed material enters the outer shell 31 through the discharge hole 323, rises with the spiral feed hopper 35 to the top through hole, and then enters the hopper 320 through the suction pipe 310, completing the crushing and discharge process.
[0068] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The material crushing device includes a base 10, a support 20, and a crushing mechanism 30. The support 20 is placed upright on the base 10, and the crushing mechanism 30 is vertically connected to the support 20. A container 1000 containing the material to be crushed is located between the crushing mechanism 30 and the base 10. The crushing mechanism 30 includes a shell 31 and a crushing component 32. The shell 31 has a bottom opening and a receiving cavity communicating with the bottom opening. The crushing component 32 is rotatably disposed in the receiving cavity. The cross-section of the shell 31 is a rounded square, and the crushing component 32 is a Reichol triangle adapted to the rounded square. The container 1000... The inner cavity shape is adapted to the outer shell 31. The crushing mechanism 30 is used to extend into the container 1000 to crush the material to be crushed. By setting the outer shell 31 of the crushing mechanism 30 to a rounded square adapted to the inner cavity of the container 1000, and setting the crushing part 32 to a Reichstag triangle adapted to the rounded square, the movement coverage area of the crushing part 32 during rotation is a rounded square, and the crushing shape of the crushing part 32 is a rounded square. This allows the material to be crushed in the container 1000 to be completely crushed in one go without secondary processing in other processes, greatly reducing the crushing steps, improving the crushing effect on agglomerated materials, and reducing production costs.
