Description

Technical Field

[0001] This application relates to the field of material grinding technology, and in particular to a grinding disc and a grinding machine. Background Technology

[0002] Natural asphalt, also known as geoasphalt or mineral asphalt, is formed when its lightweight components are evaporated and then polymerized under sunlight with oxygen from the air. It mainly consists of asphaltenes, resins, and small amounts of other inorganic substances such as metals and non-metals. Natural asphalt ore is crushed and ground, and then processing fluid is added to the resulting asphalt powder to form a natural asphalt mixture slurry.

[0003] However, the grinding discs in the relevant technologies fail to fully agitate and shear the materials during use, thus failing to utilize the maximum grinding kinetic energy of the grinding media, resulting in low grinding efficiency. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0039] One embodiment of this application provides a grinding disc; please refer to [link / reference]. Figure 1 , Figure 2 and Figure 6 The grinding disc includes a disc body, grinding components, and connectors 40.

[0040] The disk body 10 has a first disk surface and a second disk surface on opposite sides along the thickness direction.

[0041] The grinding component is disposed on the disc body 10, and a part of the grinding component is located on one side of the first disc surface and protrudes relative to the first disc surface; another part of the grinding component is located on one side of the second disc surface and protrudes relative to the second disc surface.

[0042] A portion of the connector 40 is recessed to form a first mounting groove 40a, and a portion of the disc body 10 extends into the first mounting groove 40a to be detachably connected to the connector 40. The connector 40 and the grinding assembly are engaged.

[0043] Specifically, the disc body 10 refers to the main body of the grinding disc, and the grinding components and connectors 40 are all located on the disc body 10.

[0044] The first disk surface refers to one side of the disk body 10 along the thickness direction.

[0045] The second side refers to the other side of the disk body, which is opposite to the first side and is located 10 degrees behind the first side.

[0046] The grinding assembly refers to the component located on the disc 10 and used for grinding materials.

[0047] One part of the grinding component is located on one side of the first disk surface of the disk body 10 and protrudes relative to the first disk surface, and the other part is located on one side of the second disk surface and protrudes relative to the second disk surface. The shape and size of the two protruding parts can be the same or different.

[0048] The connection method between the grinding component and the disc 10 is not limited.

[0049] For example, the grinding assembly is snapped onto the disc body 10.

[0050] For example, the grinding assembly is connected to the disc body 10 by bolts.

[0051] The connector 40 refers to the component that is mounted on the disc body 10 and engages with the grinding assembly. Thus, by engaging the grinding assembly with the connector 40, the stability of the grinding assembly during operation is ensured, reducing the risk of the grinding assembly loosening or falling off due to vibration, centrifugal force, or other factors.

[0052] The connection method between connector 40 and disk body 10 is not limited.

[0053] For example, a portion of the disk body 10 extends into the first mounting groove 40a of the connector 40 and engages with the connector 40.

[0054] For example, a portion of the disc body 10 extends into the first mounting groove 40a of the connector 40 and is bolted to the connector 40.

[0055] The grinding disc provided in this embodiment includes a disc body 10, a grinding assembly, and a connector 40. The disc body 10 has a first disc surface and a second disc surface on opposite sides along its thickness direction. The grinding assembly is disposed on the disc body 10, with a portion of the grinding assembly located on one side of the first disc surface and protruding relative to it; another portion of the grinding assembly is located on one side of the second disc surface and protrudes relative to it. A portion of the connector 40 is recessed to form a first mounting groove 40a, and a portion of the disc body 10 extends into the first mounting groove 40a for detachable connection with the connector 40. The connector 40 and the grinding assembly are engaged. Thus, on the one hand, by having the grinding assembly protrude from the first and second disc surfaces of the disc body 10 respectively, the grinding disc can simultaneously grind the material around both disc surfaces during the grinding process, improving the grinding efficiency. On the other hand, the connector 40's detachable connection to the disc body 10 and its engagement with the grinding assembly make the connection between the grinding assembly and the disc body 10 more stable, reducing the risk of the grinding assembly loosening or falling off due to vibration, centrifugal force, or other factors.

[0056] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 4 The grinding assembly includes a first grinding element 20, which is disposed on the outer edge of the disc body 10 along the circumferential direction and is engaged with the connecting member 40. Along the thickness direction, both sides of the first grinding element 20 protrude relative to the first and second disc surfaces, respectively. By placing the first grinding element 20 on the outer edge of the disc body 10 and protruding from the first and second disc surfaces, the grinding range is expanded, and the grinding efficiency is improved.

[0057] Specifically, the connection method between the first grinding element 20 and the disk body 10 is not limited.

[0058] For example, the first grinding element 20 is bolted to the outer edge of the disc body 10.

[0059] For example, the first grinding part 20 is snapped onto the outer edge of the disc body 10 via a snap fastener.

[0060] The shape and size of the two protruding parts of the first grinding element 20 protruding from the first and second disc surfaces can be the same or different.

[0061] In one embodiment, please refer to Figure 1 and Figure 5The grinding assembly includes a second grinding element 30. The disc body 10 has a mounting hole 10a penetrating the first and second disc surfaces. The second grinding element 30 is detachably inserted into the mounting hole 10a and engaged with the connector 40. Along the thickness direction, both sides of the second grinding element 30 protrude relative to the first and second disc surfaces, respectively. By inserting the second grinding element 30 into the mounting hole 10a and having both sides protrude relative to the first and second disc surfaces, the grinding disc can simultaneously grind the material around the two disc surfaces during the grinding process, improving the grinding efficiency. Furthermore, while the first grinding element 20 processes the material at the edge of the disc body 10, the second grinding element 30 grinds the material in the central area of ​​the disc body 10 and along the penetrating path, greatly expanding the grinding space and further improving the grinding efficiency of the grinding disc.

[0062] Specifically, the second grinding element 30 is inserted into the mounting hole 10a and engaged with the connector 40 to ensure that the second grinding element 30 is securely mounted on the disc body 10.

[0063] Mounting hole 10a refers to a hole located on the disc body 10 that penetrates the first and second disc surfaces for mounting the second grinding element 30.

[0064] The shape and size of the mounting hole 10a are not limited, as long as the second grinding part 30 can be inserted into the mounting hole 10a.

[0065] In one specific embodiment, the shape and size of the mounting hole 10a are adapted to the second grinding element 30. This improves the stability of the second grinding element 30 during installation and reduces the risk of it falling off during the grinding process.

[0066] The shape and size of the two protruding parts of the second grinding element 30 protruding from the first and second disc surfaces can be the same or different.

[0067] In one embodiment, please refer to Figure 1 and Figure 6The connector 40 includes a first connecting body 41 and a second connecting body 42. The first connecting body 41 is located on the side of the disc 10 with the first disc surface, and the second connecting body 42 is located on the side of the disc 10 with the second disc surface. The second grinding part 30 has a first locking groove 30a and a second locking groove 30b. The first locking groove 30a is located on the side of the disc 10 with the first disc surface, and the second locking groove 30b is located on the side of the disc 10 with the second disc surface. The first connecting body 41 engages with the first locking groove 30a, and the second connecting body 42 engages with the second locking groove 30b. Thus, through the engaging cooperation of the first connecting body 41 with the first locking groove 30a and the second connecting body 42 with the second locking groove 30b, the connector 40 can apply constraint forces to the second grinding part 30 from two directions, thereby improving the stability of the second grinding part 30 on the disc 10.

[0068] Specifically, the way the first connecting body 41 is connected to the first card slot 30a is not limited.

[0069] For example, one end of the first connecting body 41 near the first snap-fit ​​groove 30a may be disposed within the first snap-fit ​​groove 30a to snap into the second grinding member 30. Alternatively, a portion of the end face of the first connecting body 41 near the first snap-fit ​​groove 30a may protrude to form a first snap-fit ​​key, which may be disposed within the first snap-fit ​​groove 30a to snap into the second grinding member 30.

[0070] The method of engaging the second connecting body 42 with the second card slot 30b is not limited.

[0071] For example, one end of the second connecting body 42 near the second locking groove 30b may be disposed within the second locking groove 30b to engage with the second grinding member 30. Alternatively, a portion of the end face of the second connecting body 42 near the second locking groove 30b may protrude to form a second locking key, which is disposed within the second locking groove 30b to engage with the second grinding member 30.

[0072] In one specific embodiment, a portion of the first connecting body 41 near the first engaging groove 30a protrudes to form a first engaging protrusion, while a portion of the first engaging groove 30a is recessed to form a first engaging groove. When the first connecting body 41 engages with the first engaging groove 30a, the first engaging protrusion is located within the first engaging groove. This further enhances the stability of the second grinding element 30.

[0073] In one specific embodiment, a portion of the second connecting body 42 near the second engaging groove 30b protrudes to form a second engaging protrusion, while a portion of the second engaging groove 30b is recessed to form a second engaging groove. When the second connecting body 42 engages with the second engaging groove 30b, the second engaging protrusion is located within the second engaging groove. This further enhances the stability of the second grinding element 30.

[0074] In one embodiment, please refer to Figure 1 and Figure 2 A portion of the outer periphery of the disc body 10 is recessed to form a mounting step 11, and a portion of the first grinding element 20 is recessed to form a second mounting groove 20a. The first grinding element 20 is disposed at the mounting step 11, and a portion of the disc body 10 extends into the second mounting groove 20a, allowing the first grinding element 20 to be detachably connected to the disc body 10. This ensures that the first grinding element 20 is securely mounted on the disc body 10, reducing vibration and displacement during the grinding process and improving grinding accuracy and effectiveness.

[0075] Specifically, the mounting step 11 refers to the stepped structure formed by the recessed outer edge of the disc body 10. The mounting step 11 is used to mount the first grinding part 20 and serves to support and position it.

[0076] The phrase "a portion of the disc body 10 extends into the second mounting groove 20a" means that either a portion of the mounting step 11 extends into the second mounting groove 20a, or a portion of the mounting step 11 and a portion of the disc body 10 excluding the mounting step 11 both extend into the second mounting groove 20a.

[0077] In one specific embodiment, a portion of the mounting step 11 protrudes to form a second snap-fit ​​protrusion, and a portion of the groove wall on the side of the second mounting groove 20a opposite to the disc body 10 is recessed to form a second snap-fit ​​groove. The second snap-fit ​​protrusion is disposed within the second snap-fit ​​groove. This further enhances the stability of the first grinding element 20.

[0078] In one embodiment, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 The first grinding element 20 has a recessed area on the side opposite to the rotation center of the disk body 10 to form a third locking groove 20b. The connector 40 includes a locking portion 43, which engages with the third locking groove 20b. This allows for a better engagement between the connector 40 and the first grinding element 20, thereby improving the stability of the first grinding element 20 on the disk body 10.

[0079] Specifically, the snap-fit ​​part 43 refers to the structure on the connector 40 for snapping with the first grinding member 20.

[0080] The connector 40 may have all of its snap-fit ​​parts 43 located in the third snap-fit ​​groove 20b and snap-fitting with the first grinding member 20, or it may have a portion of its snap-fit ​​parts 43 located in the third snap-fit ​​groove 20b and snap-fitting with the first grinding member 20.

[0081] In one embodiment, please refer to Figure 6The engaging portion 43 protrudes from the outer edge of the disc body 10 in the circumferential direction. The engaging portion 43 has a guide surface 431 on the side opposite to the rotation center of the disc body 10. Along the rotation direction of the grinding disc, the guide surface 431 is inclined towards the side closer to the disc body 10. By providing the guide surface 431, the operating resistance can be reduced when the grinding disc is working, thereby reducing energy loss and improving grinding efficiency.

[0082] Specifically, guide surface 431 refers to the inclined surface located on the side of the snap-fit ​​portion 43 away from the rotation center of the disc body 10.

[0083] The tilt angle of the guide surface 431 is not limited, as long as it can reduce the operating resistance.

[0084] In one embodiment, please refer to Figure 3 , Figure 4 and Figure 5 The grinding assembly has a first grinding surface 50 and a second grinding surface 60. The first grinding surface 50 is disposed on the side of the grinding assembly away from the rotation center of the disc 10, and the second grinding surface 60 is disposed on the side of the grinding assembly close to the rotation center of the disc 10. Along the rotation direction of the grinding disc, the first grinding surface 50 is inclined towards the side closer to the disc 10, and the second grinding surface 60 is inclined towards the side away from the disc 10. This can further reduce the operating resistance of the grinding disc during operation and further improve the grinding efficiency.

[0085] Specifically, the tilt angle of the first grinding surface 50 and the second grinding surface 60 is not limited, as long as it can reduce the operating resistance.

[0086] Understandably, the external dimensions of the grinding assembly gradually decrease along the direction of rotation of the grinding disc.

[0087] In one embodiment, the grinding assembly has a third grinding surface 100 and a fourth grinding surface 101. The third grinding surface 100 is disposed on the side of the grinding assembly located on the first disc surface, and the fourth grinding surface 101 is disposed on the side of the grinding assembly located on the second disc surface. Along the direction from near the first disc surface to away from the first disc surface, the third grinding surface 100 is inclined towards the side away from the first disc surface, and along the direction from near the second disc surface to away from the second disc surface, the fourth grinding surface 101 is inclined towards the side away from the second disc surface. This further reduces the operating resistance of the grinding disc during operation and improves grinding efficiency.

[0088] Specifically, the tilt angles of the third grinding surface 100 and the fourth grinding surface 101 are not limited, as long as they can reduce the operating resistance.

[0089] It is understandable that the third grinding surface 100 and the fourth grinding surface 101 can be either planes or lines.

[0090] In one specific embodiment, the first grinding element 20 includes a first grinding portion and a second grinding portion. The first grinding portion is located on one side of the first disc surface and protrudes relative to the first disc surface, while the second grinding portion is located on one side of the second disc surface and protrudes relative to the second disc surface. Along the rotation direction of the grinding disc, the cross-sectional area of ​​at least a portion of the first grinding portion and at least a portion of the second grinding portion gradually decreases. Therefore, the operating resistance can be reduced when the grinding disc is working, thereby reducing energy loss and improving grinding efficiency.

[0091] In one specific embodiment, a portion of the first grinding part facing away from the first grinding surface 50 is opened to form a first opening, and a portion of the second grinding part facing away from the first grinding surface 50 is opened to form a second opening. This reduces the overall weight of the first grinding part 20 and also saves costs.

[0092] It is understandable that the cross-sectional dimensions of the first opening can be the same or vary along the direction of rotation of the grinding disc.

[0093] For example, the cross-sectional size of the first opening gradually decreases along the rotation direction of the grinding disc.

[0094] It is understandable that the cross-sectional dimensions of the second opening can be the same or vary along the direction of rotation of the grinding disc.

[0095] For example, the cross-sectional size of the second opening gradually decreases along the rotation direction of the grinding disc.

[0096] In one specific embodiment, the second grinding member 30 includes a third grinding portion and a fourth grinding portion. The third grinding portion is located on one side of the first disc surface and protrudes relative to the first disc surface, while the fourth grinding portion is located on one side of the second disc surface and protrudes relative to the second disc surface. Along the rotation direction of the grinding disc, the cross-sectional area of ​​at least a portion of the third grinding portion and at least a portion of the fourth grinding portion gradually decreases. Therefore, the operating resistance can be reduced when the grinding disc is working, thereby reducing energy loss and improving grinding efficiency.

[0097] In one specific embodiment, a portion of the third grinding part facing away from the first grinding surface 50 is opened to form a third opening, and a portion of the fourth grinding part facing away from the first grinding surface 50 is opened to form a fourth opening. This reduces the overall weight of the second grinding element 30 and also saves costs.

[0098] It is understandable that the cross-sectional dimensions of the third opening can be the same or vary along the direction of rotation of the grinding disc.

[0099] For example, the cross-sectional size of the third opening gradually decreases along the rotation direction of the grinding disc.

[0100] It is understandable that the cross-sectional dimensions of the fourth opening can be the same or vary along the direction of rotation of the grinding disc.

[0101] For example, the cross-sectional size of the fourth opening gradually decreases along the rotation direction of the grinding disc.

[0102] In one embodiment, please refer to Figure 1 The grinding assembly includes a second grinding element 30. The disc body 10 has a mounting hole 10a that penetrates the first disc surface and the second disc surface. The second grinding element 30 is detachably inserted into the mounting hole 10a and is engaged with the connector 40. Along the thickness direction, the two sides of the second grinding element 30 protrude relative to the first disc surface and the second disc surface, respectively.

[0103] The grinding disc includes multiple first grinding elements 20, multiple connecting elements 40, and multiple second grinding elements 30. Each first grinding element 20 and each connecting element 40 is arranged in a one-to-one correspondence and is spaced apart around the circumference of the disc body 10. Each second grinding element 30 is arranged spaced apart around the rotation center of the disc body 10. Thus, by providing multiple first grinding elements 20 and second grinding elements 30, the grinding efficiency of the grinding disc is improved.

[0104] Specifically, the spacing between the first grinding elements 20 arranged circumferentially around the disk body 10 is not limited.

[0105] The spacing between the second grinding elements 30 arranged circumferentially around the rotation center of the disk body 10 is not limited.

[0106] The one-to-one correspondence between each first grinding component 20 and each connecting component 40 means that the number of first grinding components 20 and the number of connecting components 40 are the same, and they are snapped together in a one-to-one correspondence.

[0107] In one embodiment, the grinding disc further includes a weight-reducing hole 10b. This reduces the overall weight of the grinding disc.

[0109] The number of weight-reducing holes 10b is unlimited. For example, there can be one or more weight-reducing holes 10b.

[0110] Another embodiment of this application provides a grinding machine; please refer to [link / reference]. Figure 7 The grinding machine includes a grinding cylinder, a connecting shaft 70, a grinding disc and a driving component in any of the above embodiments.

[0111] At least a portion of the connecting shaft 70 is rotatably disposed within the grinding cylinder.

[0112] The grinding disc is mounted on the connecting shaft 70.

[0113] The driving component is connected to the connecting shaft 70, and the driving component drives the connecting shaft 70 to rotate so as to drive the grinding disc to rotate.

[0114] Specifically, a grinding cylinder refers to a component used to house a grinding disc and provide a closed grinding environment for materials.

[0115] A portion of the connecting shaft 70 is connected to the drive component, while another portion is connected to the connecting shaft 70. This allows the rotational force generated by the drive component to be transmitted to the grinding disc, ensuring high-speed and stable rotation of the grinding disc.

[0116] The connection method between the connecting shaft 70 and the grinding disc is not limited.

[0117] For example, the connecting shaft 70 is engaged with the grinding disc.

[0118] Understandably, the grinding disc has a connecting hole, and the connecting shaft 70 passes through the connecting hole and connects to the grinding disc.

[0119] In one embodiment, please refer to Figure 7 The grinding machine includes multiple grinding discs, including at least one first grinding disc 80 and at least one second grinding disc 90. The outer dimensions of the first grinding disc 80 are larger than those of the second grinding disc 90. The first grinding disc 80 and the second grinding disc 90 are alternately arranged along the extending direction of the connecting shaft 70. This reduces dead zones during operation and increases grinding kinetic energy during operation, thereby improving grinding efficiency.
