DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0045] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in the present invention, unless otherwise specified, include direct and indirect connections (couplings). In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is 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 orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0046] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0047] Please refer to Figure 1 to Figure 2The present invention proposes an auxiliary fixing device 10 suitable for a ball mill 300 .

[0048] It is understood that the ball mill 300 includes a barrel 310 and a liner assembly 20, wherein the barrel 310 is used to load the ball mill and the material, wherein the ball mill utilizes the friction between the ball mill and the liner assembly 20 and the impact of the ball mill to achieve the research and development of the material, specifically, after the material is fed into the barrel 310 and the ball mill is working, due to the rotation of the barrel 310 and the free falling movement of the ball mill, the material will be crushed and ground after being subjected to the impact force of the ball mill and the friction force generated between the ball mill and the liner assembly 20. The liner assembly 20 is arranged on the inner wall of the barrel 310, and its function is to prevent the inner wall of the barrel 310 from being directly impacted by the ball mill and the material, so as to effectively extend the service life of the barrel 310 and the ball mill 300; wherein the liner assembly 20 includes a plurality of liners 21.

[0049] Please refer to Figures 1 to 4 The auxiliary fixing device 10 is used to assist the lining plate 21 to be fixed on the inner wall of the cylinder 310. Specifically, the auxiliary fixing device 10 includes a limiting assembly 11, and the limiting assembly 11 includes a plurality of limiting structures 111, and the plurality of limiting structures 111 are arranged at intervals along the circumference of the cylinder 310, and the limiting structure 111 includes a limiting member 112 and a connecting member (not shown in the figure).

[0050] The stopper 112 may be provided in a strip shape, and the stopper 112 is provided on the inner wall of the cylinder 310. The connecting member may be a member having a connecting function such as a combination of a bolt and a nut, and the connecting member is used to connect the cylinder 310 and the stopper 112. For example, if the connecting member is a combination of a bolt and a nut, the bolt will penetrate the stopper 112 and the cylinder 310, and then be connected with the nut, so that the stopper 112 is fixed to the inner wall of the cylinder 310.

[0051] Any two adjacent stoppers 112 cooperate with the inner wall of the cylinder 310 to form a stopper groove 113, which is used for the installation of the liner 21 and plays a role in limiting and fixing the liner 21. In the actual assembly process, a stopper 112 can be first fixed to the inner wall of the cylinder 310 through a connector, and then a liner 21 is spliced ​​and placed on one side of the stopper 112, and then another stopper 112 is spliced ​​with the liner 21 and fixed to the inner wall of the cylinder 310 through a connector. In this way, the liner 21 can be fixed to the inner wall of the cylinder 310 by being embedded in the stopper groove 113 formed by the two stoppers 112 and the cylinder 310. During disassembly and assembly, after the stopper 112 is disassembled and separated from the cylinder 310, the liner 21 can be removed and separated from the cylinder 310, so that the subsequent replacement and maintenance of the liner 21 is very convenient, saving a lot of disassembly and assembly time.

[0052] At the same time, in order to facilitate the splicing of the lining plate 21 and the limiting member 112, at least a portion of the side wall of the limiting groove 113 is formed with a guide bevel 1131, that is, a portion of the side wall of the limiting groove 113 can be formed with a guide bevel 1131, or the side wall of the limiting groove 113 can be formed as a whole as a guide bevel 1131, and the guide bevel 1131 is used to guide the lining plate 21 into the limiting groove 113. In this way, the lining plate 21 is guided to the splicing position by the guiding action of the guiding bevel 1131, and the assembly is convenient and quick. Moreover, when the last lining plate 21 is installed, the limiting parts 112 are actually assembled on the left and right sides of the installation position where the lining plate 21 is located, and the limiting grooves 113 are constructed. Therefore, during the assembly process, the lining plate 21 can enter the limiting grooves 113 through the cooperation of the guiding bevel 1131. In this way, even if there are assembly errors in the previous installation process, the installation tolerance for the last lining plate 21 is relatively large, thereby effectively improving the assembly efficiency.

[0053] Please refer to Figure 3 to Figure 4 In some embodiments, the size of the notch of the limiting groove 113 is smaller than the size of the bottom wall of the limiting groove 113. It is understandable that the cross section of the limiting groove can be roughly wedge-shaped or trapezoidal, so that after the liner 21 is embedded in the limiting groove 113, the guide slope 1131 can play a role of limiting and blocking the liner 21, so that during the operation of the ball mill 300, the liner 21 is not easy to be separated from the limiting groove 113, thereby effectively improving the fixing stability of the liner 21 and the cylinder 310.

[0054] Please refer to Figure 3 to Figure 4 In some embodiments, the guide bevel 1131 includes a first bevel section 1131A and a second bevel section 1131B, and the first bevel section 1131A is provided with a notch. It is understandable that during the assembly process, the liner 21 will slide along the first bevel section 1131A and the second bevel section 1131B to be integrally embedded in the limiting groove 113.

[0055] The first bevel section 1131A has a greater inclination than the second bevel section 1131B. It should be noted that the inclination referred to here refers to the inclination of the first bevel section 1131A and the second bevel section 1131B relative to the radial direction passing through the stopper 112. The first bevel section 1131A is used to limit the liner 21 in the radial direction of the cylinder 310, and the second bevel section 1131B is used to limit the liner 21 in the circumferential direction of the cylinder 310.

[0056] After the liner 21 is embedded in the limiting groove 113, it will fit with the first bevel section 1131A and the second bevel section 1131B, so that the first bevel section 1131A and the second bevel section 1131B can limit and resist the liner 21. In this way, the limiting groove 113 can limit and resist the liner 21 in the radial and circumferential directions of the cylinder 310, so as to more effectively prevent the liner 21 from escaping from the limiting groove 113. After the actual assembly is completed, the first bevel section 1131A and the second bevel section 1131B of the guide bevel 1131 will fit with the side of the liner 21, so as to ensure that the gap between the side of the liner 21 and the guide bevel 1131 is small, greatly reducing the possibility of material entering the gap, thereby effectively preventing the material from entering the gap and causing wear to the liner 21.

[0057] Please refer to Figure 3 to Figure 4 In some embodiments, the two groove side walls of the limiting groove 113 opposite to each other along the circumference of the cylinder 310 are both formed with guide slopes 1131. In this way, not only can the stability of the lining plate 21 fixed in the limiting groove 113 be improved, but also the last lining plate 21 can be easily installed, and the operation is very convenient.

[0058] Please refer to Figures 1 to 5 The present invention further proposes a ball mill liner 100, which is suitable for a ball mill 300. The ball mill liner 100 includes a liner assembly 20 and an auxiliary fixing device 10. The specific structure of the auxiliary fixing device 10 refers to the above embodiment, so it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0059] The lining plate assembly 20 includes a plurality of lining plates 21 , and the plurality of lining plates 21 are arranged in a one-to-one correspondence in the plurality of limiting grooves 113 .

[0060] Please refer to Figures 5 to 7 In some embodiments, the lining plate 21 includes a base plate 211 , a first vibration damping plate 212 , and a second vibration damping plate 213 , and the base plate 211 supports the first vibration damping plate 212 and the second vibration damping plate 213 , wherein the base plate 211 is disposed in the limiting groove 113 .

[0061] The first vibration damping plate 212 and the second vibration damping plate 213 are both connected to the surface of the base plate 211 facing away from the cylinder 310 along the radial direction of the cylinder 310 , and are respectively disposed on two opposite sides of the base plate 211 along the width direction thereof.

[0062] The first vibration damping plate 212 and the second vibration damping plate 213 are arranged alternately along the length direction of the base plate 211 .

[0063] It is understandable that during the initial operation of the ball mill 300, as the ball mill body and the material tumble in the cylinder 310, the ball mill body and the material will fall onto the first vibration damping plate 212 and the second vibration damping plate 213, and will exert a force on the first vibration damping plate 212 and the second vibration damping plate 213, and the first vibration damping plate 212 and the second vibration damping plate 213 will usually transmit the circumferential force to the base plate 211. However, in the present invention, since the first vibration damping plate 212 and the second vibration damping plate 213 are staggered along the length direction of the base plate 211, the force acting on the first vibration damping plate 212 can be opposite to the force of the second vibration damping plate 213, and can offset each other when acting on the base plate 211, thereby avoiding the force from being transmitted to the limiting structure 111 and preventing the connecting parts from being deformed due to the influence of the force, making it difficult to disassemble the subsequent connecting parts.

[0064] Please refer to Figure 6 to Figure 7 In some embodiments, the first vibration damping plate 212 has a first inclined surface 2121 , and the second vibration damping plate 213 has a second inclined surface 2131 . In the same liner 21 , the first inclined surface 2121 and the second inclined surface 2131 are disposed opposite to each other in the circumferential direction of the cylinder 310 .

[0065] The heights of the first inclined surface 2121 and the second inclined surface 2131 adjacent to the same limiting member 112 have the same changing trend along the first direction or the second direction; and the heights of the first inclined surface 2121 adjacent to two adjacent limiting members 112 have opposite changing trends along the first direction or the second direction, and the heights of the second inclined surfaces 2131 adjacent to two adjacent limiting members 112 have opposite changing trends along the first direction or the second direction.

[0066] like Figure 6 As shown, there are four rows of vibration damping plates. The height of the first inclined surface 2121 on the left side of the stopper 112 in the figure (i.e., the inclined surface on the second row of vibration damping plates along the third direction) has a tendency to gradually increase along the first direction, that is, the height of the first inclined surface 2121 has a tendency to gradually decrease along the second direction, and the height of the second inclined surface 2131 on the right side of the stopper 112 in the figure (i.e., the inclined surface on the third row of vibration damping plates along the third direction) has a tendency to gradually increase along the first direction, that is, the height of the second inclined surface 2131 has a tendency to gradually decrease along the second direction.

[0067] Figure 6 The first inclined surface 2121 on the first vibration damping plate 212 located in the rightmost column (which is adjacent to the limiting member located on the right side thereof, but Figure 6 The height of the limiting member (not shown) has a tendency to gradually decrease along the first direction, that is, the height of the first inclined surface 2121 has a tendency to gradually increase along the second direction.

[0068] Figure 6 The second inclined surface 2131 on the second vibration damping plate 213 located in the leftmost column (which is adjacent to the limiting member located on the left side thereof, but Figure 6 The height of the limiting member (not shown) has a tendency to gradually decrease along the first direction, that is, the height of the second inclined surface 2131 has a tendency to gradually increase along the second direction.

[0069] The first direction is opposite to the second direction, and the first direction is parallel to the length direction of the substrate 211 .

[0070] It can be understood that as the ball mill and the material tumble in the cylinder 310, the ball mill and the material will fall on the first inclined surface 2121 of the first vibration damping plate 212 and the second inclined surface 2131 of the second vibration damping plate 213. Based on this, under the guidance of the first inclined surface 2121 and the second inclined surface 2131, a part of the ball mill and the material will move in the first direction, and a part of the ball mill and the material will move in the second direction. In this way, the ball mill and the material can be distributed more evenly in the cylinder 310, avoiding the ball mill and the material always moving in the same direction and accumulating on one side during the operation of the ball mill 300, so as to effectively improve the grinding effect of the ball mill on the material. Furthermore, the first inclined surface 2121 and the second inclined surface 2131 adjacent to the same limiting member 112 have the same guiding effect on the spheroidal graphite body and the material in the first direction or the second direction, while for two adjacent limiting members 112, the first inclined surface 2121 and the second inclined surface 2131 have opposite guiding effects on the spheroidal graphite body and the material in the first direction or the second direction.

[0071] Please refer to Figure 6 , Figure 7 as well as Fig.10 , further, the heights of the first inclined surface 2121 and the second inclined surface 2131 adjacent to the same stopper 112 have opposite changing trends along the third direction or the fourth direction; the height of the first inclined surface 2121 also has a tendency to gradually decrease along the third direction, and the height of the second inclined surface 2131 also has a tendency to gradually decrease along the fourth direction, and the third direction is opposite to the fourth direction and is set at an angle to the first direction. Among them, the first vibration damping plate 212 and the second vibration damping plate 213 can both slide relative to the base plate 211 along the circumference of the cylinder 310, so that the first vibration damping plate 212 and the second vibration damping plate 213 can move in a direction close to each other under the action of external force.

[0072] Thus, in the initial stage of grinding, when the ball mill is a steel ball and falls on the material to crush the material, the material has already consumed energy on the ball mill, so the force of the ball mill has been reduced, and therefore the difference in force of the ball mill acting on different areas of the substrate 211 through the first vibration damping plate 212 and the second vibration damping plate 213 will be smaller, so that the forces can offset each other; and when it reaches the later stage of grinding, the particles of the material are already smaller, and the energy consumption effect on the ball mill is also smaller. At this time, the difference in force of the ball mill acting on different areas of the substrate 211 through the first vibration damping plate 212 and the second vibration damping plate 213 is large, and cannot be offset well.

[0073] Therefore, the present invention sets the first inclined surface 2121 and the second inclined surface 2131 to change their heights at multiple angles, so that the first vibration damping plate 212 and the second vibration damping plate 213 can slide close to each other when they are subjected to the force of the ball mill falling on the liner 21, so that the position of the ball mill falling on the liner 21 is finally at Fig.10 In the dotted frame in the figure, the force exerted by the ball mill falling on the liner 21 will act on the first vibration damping plate 212 and the second vibration damping plate 213 at the same time. Compared with the form in which the force of the ball mill acts on the first vibration damping plate 212 and the second vibration damping plate 213 respectively, the present invention makes the difference in the force finally acting on the base plate 211 smaller, thereby reducing the force received by the liner 21 in the circumferential direction, thereby avoiding lateral extrusion of the limiting structure 111 and causing deformation of the connecting part.

[0074] Please refer to Figures 5 and 6 In some embodiments, the ball mill liner 100 further includes a locking assembly 30, which includes a screw 31 and a nut 32. The screw 31 passes through the first vibration damping plate 212 and the second vibration damping plate 213, and is threadedly connected to the nut 32 to make the first vibration damping plate 212 and the second vibration damping plate 213 relatively still.

[0075] It is understandable that before the ball mill 300 works, the screw 31 can be passed through the first vibration damping plate 212 and the second vibration damping plate 213 and locked with the nut 32, and then the initial grinding work of the ball mill 300 is started. When the ball mill 300 is in the later grinding work, the grinding work of the ball mill 300 is suspended, and then the locking components 30 are removed one by one. When removing, the nut 32 and the screw 31 of one locking component 30 are first removed, and the cylinder 310 is controlled to rotate slowly, and the rotation is stopped after rotating at an appropriate angle, and then the nut 32 and the screw 31 of another locking component 30 are removed, until all the locking components 30 are removed, so that the first vibration damping plate 212 and the second vibration damping plate 213 can slide relative to the base plate 211 by removing the nut 32 and the screw 31. After the grinding is completed and the material is sent out, before the next operation of the ball mill 300 is restarted, when it is necessary to lock the first vibration damping plate 212 and the second vibration damping plate 213 again, the cylinder 310 can be rotated. When the first vibration damping plate 212 and the second vibration damping plate 213 move upward and the ball mill body falls due to its own gravity, the force of the ball mill body on the first vibration damping plate 212 and the second vibration damping plate 213 disappears, so that the first vibration damping plate 212 and the second vibration damping plate 213 can be reset, so that the screw rod 310 can be installed again. and the nut 32, specifically, firstly, the first vibration damping plate 212 and the second vibration damping plate 213 of the upper lining plate 21 are locked by the screw 31 and the nut 32 of a locking assembly 30. After locking, the control cylinder 310 is rotated slowly, and the rotation is stopped after rotating to a proper angle, and then another locking assembly 30 is used to lock the first vibration damping plate 212 and the second vibration damping plate 213 of the other lining plate 21 located above at this time, until all the locking assemblies 30 are installed. It is easy to operate and has a simple structure.

[0076] Please refer to Figures 8 to 9 In some embodiments, the lining plate 21 further includes a first elastic member 214 and a second elastic member 215. The first elastic member 214 is disposed between the first vibration damping plate 212 and the base plate 211 to provide a rebound force for the first vibration damping plate 212 in the circumferential direction of the cylinder 310, and the second elastic member 215 is disposed between the second vibration damping plate 213 and the base plate 211 to provide a rebound force for the second vibration damping plate 213 in the circumferential direction of the cylinder 310.

[0077] It can be understood that when the cylinder 310 is rotated and the first vibration damping plate 212 and the second vibration damping plate 213 are moved upward, the material and the ball mill fall due to their own gravity, and the force exerted by the material and the ball mill on the first vibration damping plate 212 and the second vibration damping plate 213 will disappear. At this time, under the action of the rebound force, the first vibration damping plate 212 and the second vibration damping plate 213 can be automatically reset, which is easy to operate. When the material and the ball mill exert a force on the first vibration damping plate 212 and the second vibration damping plate 213, the force will be greater than the rebound force, so the first vibration damping plate 212 and the second vibration damping plate 213 can overcome the force and achieve sliding.

[0078] Please refer to Figures 8 to 9 In some embodiments, one of the first vibration damping plate 212 and the substrate 211 is provided with a first slider 2122, and the other is provided with a first slide groove 2112A, and the first slider 2122 is slidably disposed in the first slide groove 2112A so that the first vibration damping plate 212 can slide relative to the substrate 211 along the circumference of the cylinder 310, and one of the second vibration damping plate 213 and the substrate 211 is provided with a second slider 2132, and the other is provided with a second slide groove 2113A, and the second slider 2132 is slidably disposed in the second slide groove 2113A so that the second vibration damping plate 213 can slide relative to the substrate 211 along the circumference of the cylinder 310.

[0079] Among them, the first slider 2122 can slide along the extension direction of the first slide groove 2112A, and the second slider 2132 can slide along the extension direction of the second slide groove 2113A, thereby playing a guiding effect, avoiding the first vibration damping plate 212 from shifting when sliding relative to the substrate 211, and also avoiding the second vibration damping plate 213 from shifting when sliding relative to the substrate 211.

[0080] Specifically, the first elastic member 214 can be arranged in the first slide groove 2112A, and one end of it abuts against the first slider 2122, and the other end abuts against the side wall of the first slide groove 2112A; the second elastic member 215 can be arranged in the second slide groove 2113A, and one end of it abuts against the second slider 2132, and the other end abuts against the side wall of the second slide groove 2113A.

[0081] Please refer to Figures 7 to 10In some embodiments, the base plate 211 includes a support plate 2111, a first side plate 2112, and a second side plate 2113. The support plate 2111, the first side plate 2112, the second side plate 2113, the first vibration damping plate 212, and the second vibration damping plate 213 can all be made of rubber or metal. When made of rubber, the first vibration damping plate 212 and the second vibration damping plate 213 have good vibration damping performance and are suitable for use in high impact load scenarios. When made of metal, the first vibration damping plate 212 and the second vibration damping plate 213 have good wear resistance and effectively extend the service life of the ball mill 300. This embodiment does not specifically limit the materials of the first vibration damping plate 212 and the second vibration damping plate 213.

[0082] The first side plate 2112 is spliced ​​on the support plate 2111 and connected to the first vibration damping plate 212. The first side plate 2112 may be provided with the above-mentioned first slide groove 2112A or the first slider 2122. When the first side plate 2112 is subjected to an external force, it can be arranged in a close fit with the support plate 2111. The second side plate 2113 is spliced ​​on the support plate 2111 and connected to the second vibration damping plate 213. The second side plate 2113 may be provided with the above-mentioned second slide groove 2113A or the second slider 2132. When the second side plate 2113 is subjected to an external force, it can be arranged in a close fit with the support plate 2111.

[0083] In this way, when the material and the ball mill generate a force on the first vibration damping plate 212 and the second vibration damping plate 213, as the force is transmitted to the first side plate 2112 and the second side plate 2113, the spliced ​​first side plate 2112 and the support plate 2111 can be sealed and fitted, and the spliced ​​second side plate 2113 and the support plate 2111 can be sealed and fitted, which can greatly reduce the risk of the material entering the gap between the first side plate 2112 and the support plate 2111, and greatly reduce the risk of the material entering the gap between the second side plate 2113 and the support plate 2111, thereby avoiding the material from causing wear to the first side plate 2112, the second side plate 2113 and the support plate 2111.

[0084] Please refer to Figures 7 to 9 In some embodiments, the first vibration damping plate 212 and the second vibration damping plate 213 each include a vibration damping plate body 216 and a covering portion 217 connected to each other.

[0085] The damping plate body 216 of the first damping plate 212 is fixedly connected to the first slider 2122, so that when the first slider 2122 slides in the first chute 2122A, it can drive the damping plate body 216 of the first damping plate 212 to slide, thereby making the first damping plate 212 slide as a whole. It is understandable that the damping plate body 216 and the covering portion 217 of the first damping plate 212 can cooperate to cover the first chute 2122A to prevent materials with smaller particles after grinding from entering the first chute 2122A and blocking the first chute 2122A after long-term use, thereby ensuring the smoothness of the cooperation between the first slider 2122 and the first chute 2122A.

[0086] The damping plate body 216 of the second damping plate 213 is fixedly connected to the second slider 2132, so that when the second slider 2132 slides in the second chute 2113A, it can drive the damping plate body 216 of the second damping plate 213 to slide, thereby making the second damping plate 213 slide as a whole. It is understandable that the damping plate body 216 and the covering portion 217 of the second damping plate 213 can cooperate to cover the second chute 2113A to prevent materials with smaller particles after grinding from entering the second chute 2113A and causing the second chute 2113A to be blocked after long-term use, thereby ensuring the smoothness of the cooperation between the second slider 2132 and the second chute 2113A.

[0087] The assembly and working process of this embodiment are as follows: before the ball mill 300 starts grinding, a limit piece 112 is first fixed to the inner wall of the cylinder 310, and then a liner 21 is spliced ​​and placed on one side of the limit piece 112, and the first vibration damping plate 212 and the second vibration damping plate of the liner 21 are locked by the locking assembly, and then another limit piece 112 is spliced ​​with the liner 21, and then the cylinder 310 is controlled to rotate slowly, and after rotating to an appropriate angle, it stops rotating, and another liner 21 is spliced, and this cycle is repeated until the ball mill liner 100 is assembled as a whole. After assembly, the material is sent into the ball mill liner 100, and then the ball mill 300 starts to work and grinds the material. In the later stage of grinding, when the particles of the material become smaller, the operation of the ball mill 300 is suspended, and then the locking components 30 are removed one by one. When removing, after removing one locking component 30, the cylinder 310 is controlled to rotate slowly, and the rotation is paused after rotating at an appropriate angle, and then another locking component 30 is removed until all the locking components 30 are removed, and then the ball mill 300 is controlled to continue working until the grinding is completed. After the grinding is completed, the ground material is sent out of the ball mill 300 to achieve a complete grinding process.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
