Description

Technical Field

[0001] This utility model relates to the field of auxiliary components for mill liners, specifically to a mill liner that can improve the impact force of the bars. Background Technology

[0002] Rod mill liners are wear-resistant plates used to protect the cylinder from direct impact and friction between the grinding media and materials. Different types of liners can also be used to adjust the movement of the grinding media to enhance the crushing effect of the grinding media on the materials, thereby improving the grinding efficiency of the mill, increasing output, and reducing metal consumption.

[0003] In the existing technology, specifically in the actual use of rod mills, when the main function of the rod mill is to crush materials, it is necessary to use liners to provide strong lifting capacity for the rods so that the rods can fall at a higher elevation, thereby generating a strong impact force to crush the materials. However, the existing liners are not designed with a structure on their surface that can provide strong lifting capacity, which results in a limited elevation to which the liners can lift the rods, leading to a weak impact force generated by the rods. Utility Model Content

[0004] The purpose of this invention is to provide a mill liner that can improve the impact force of the bars in order to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a mill liner plate that can improve the impact force of the bar, including a liner plate body. The top surface of the liner plate body has multiple mounting bolt holes from top to bottom, and each mounting bolt hole is coaxially inserted with a mounting bolt for installation at the layout position.

[0007] The top of the liner body is provided with wear-resistant liner blocks at the positions corresponding to each of the mounting bolt holes to enhance the lifting capacity of the bar. Each wear-resistant liner block is assembled with a connecting piece, and each wear-resistant liner block is detachably fixed to the top of the liner body through the corresponding connecting piece.

[0008] Preferably, the mounting bolt holes are countersunk bolt holes, and all mounting bolt components are countersunk bolt components adapted to the mounting bolt holes.

[0009] Preferably, the upper part of the mounting bolt holes is a countersunk hole, and the top of the mounting bolt is lower than the top of the countersunk hole.

[0010] Preferably, the top of each countersunk hole is coaxially and detachably fitted with a sealing cap for sealing, and the top surface of each sealing cap is connected to the part corresponding to the combined connecting member.

[0011] Preferably, the top of the inner circumference of the countersunk hole is provided with internal threads, and the outer circumference of the cover is provided with external threads. The cover is detachably connected to the top of the corresponding countersunk hole through threaded engagement.

[0012] Preferably, the upper and lower parts of the wear-resistant liner are a dovetail block and a rectangular block, respectively.

[0013] Preferably, each of the combined connectors includes a mating block and a mating slot. The top surface of each cover is vertically fixed with the mating block, and the front end face of each mating block is longitudinally provided with a locking hole. The bottom surface of each wear-resistant liner is vertically provided with the mating slot, and the mating block and the corresponding mating slot are vertically slidably engaged. The front end face of each wear-resistant liner is longitudinally provided with a mating hole, and the mating hole is vertically connected to the corresponding mating slot. At the same time, the mating hole and the corresponding locking hole are longitudinally coaxially aligned. Each set of coaxially aligned mating holes and locking holes is detachably fitted with a locking bolt along the longitudinal axis.

[0014] Preferably, both the mating hole and the locking hole are internally threaded through holes, and the locking bolts are coaxially combined with the corresponding mating hole and the locking hole through threaded engagement.

[0015] Preferably, the front end face of the wear-resistant liner is provided with a hidden hole coaxially at the position corresponding to the mating hole, the front end head of the locking bolt is recessed into the corresponding hidden hole, and the outer periphery of the front end head of the locking bolt does not contact the inner periphery of the hidden hole.

[0016] Preferably, anti-loosening washers are slidably fitted around the periphery of the front end of the locking bolt extending from the mating hole, and the anti-loosening washers are pressed into the hidden hole by the front end of the corresponding locking bolt.

[0017] The mill liner plate described above, which enhances the impact force of the grinding bars, is used in practical applications. Multiple wear-resistant blocks are installed on the surface of the liner plate body via the connecting assembly. These prominent wear-resistant blocks on the liner plate body surface can lift the grinding bars to a higher elevation before they fall, thus stably increasing the crushing impact force of the bars. Furthermore, the upper and lower parts of each wear-resistant block are dovetail and rectangular blocks, respectively. The dovetail design of the upper part further increases the elevation of the rising grinding bars, contributing to a more stable and enhanced impact force. Specifically, when assembling the wear-resistant blocks on the top surface of the liner plate body, the vertical sliding engagement of the connecting assembly's slots with the mating blocks and the longitudinal passage of the locking bolts through the mating holes and locking holes allows for the detachable assembly of the wear-resistant blocks onto the liner plate body. At the top, simply by turning the locking bolts to sequentially disengage them from the locking hole and the mating hole, the mating slot can be separated vertically from the mating insert, thus allowing the wear-resistant liner to be removed from the top of the liner body. The assembly and disassembly of the wear-resistant liner on the top of the liner body is simple and easy to implement. It facilitates the quick assembly of the wear-resistant liner on the top of the liner body for use, and also facilitates subsequent replacement and maintenance after the wear-resistant liner is removed from the top of the liner body. Furthermore, because the cover and the countersunk portion of the mounting bolt hole are coaxially engaged, the mating insert of the assembly connector can be assembled on the top of the liner body. Then, by sealing the top of the mounting bolt hole with the cover, materials can be prevented from entering the mounting bolt hole, achieving isolation and protection of the mounting bolt components and helping to slow down the erosion of the mounting bolt components by corrosive materials.

[0018] The beneficial effects are as follows: 1. Multiple wear-resistant lining blocks are installed on the surface of the lining body by means of a combination connector. Then, the wear-resistant lining blocks with high protrusion on the surface of the lining body can drive the bar to rise to a higher elevation and then fall, thereby stably improving the crushing impact force of the bar.

[0019] 2. The upper and lower parts of the wear-resistant liner are dovetail blocks and rectangular blocks, respectively. The design of the upper part of the wear-resistant liner as a dovetail block can further increase the elevation when the bar rises, which helps to further stabilize and improve the impact force of the bar.

[0020] 3. By using the vertical sliding fit between the fitting slot and the fitting block of the combined connector, and the locking bolt passing through the fitting hole and locking hole in sequence along the longitudinal direction, the wear-resistant liner can be detachably assembled on the top of the liner body. At the same time, by simply turning the locking bolt out of the locking hole and fitting hole in sequence, the fitting slot can be separated from the fitting block in the vertical direction, so that the wear-resistant liner can be removed from the top of the liner body. The assembly and disassembly of the wear-resistant liner on the top of the liner body is simple and easy to implement. It is convenient to quickly assemble the wear-resistant liner on the top of the liner body for use, and it is also convenient to replace and maintain the wear-resistant liner after it is removed from the top of the liner body.

[0021] 4. By coaxially engaging the cover with the countersunk portion of the mounting bolt hole, the mating insert of the combined connector can be assembled on the top of the liner body. Then, by sealing the top of the mounting bolt hole with the cover, materials can be prevented from entering the mounting bolt hole, thus achieving isolation and protection of the mounting bolt components and helping to slow down the erosion of the mounting bolt components by corrosive materials.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] See Figures 1-6 As shown, this utility model provides a mill liner that can improve the impact force of the bar. It includes a liner body 2, with multiple mounting bolt holes 5 formed from top to bottom on the top surface of the liner body 2. Each mounting bolt hole 5 is coaxially fitted with a mounting bolt 4 for installation at a designated location. Wear-resistant liner blocks 1 are provided at the top of the liner body 2 at positions corresponding to each mounting bolt hole 5 to enhance the lifting capacity of the bar. Each wear-resistant liner block 1 is assembled with a connecting member 3, and each wear-resistant liner block 1 is detachably fixed to the top of the liner body 2 via the corresponding connecting member 3. Specifically, each connecting member 3 includes a mating insert 305 and a mating slot 304. The top surface of the cover 6 is vertically fixed with mating inserts 305, and the front end face of each mating insert 305 has a locking hole 306 along the longitudinal direction. The bottom center of each wear-resistant liner block 1 has a vertically formed mating slot 304, and the mating insert 305 and the corresponding mating slot 304 are vertically slidably engaged. The front end face of the wear-resistant liner 1 is provided with mating holes 307 along the longitudinal direction, and each mating hole 307 is perpendicularly connected to the corresponding mating slot 304. At the same time, each mating hole 307 is longitudinally coaxially aligned with the corresponding locking hole 306. Each set of coaxially aligned mating holes 307 and locking holes 306 is detachably fitted with locking bolts 303 along the longitudinal direction. The purpose of this arrangement is to enable vertical sliding engagement and locking between the mating slot 304 of the combined connector 3 and the mating insert 305. The bolt 303 passes through the mating hole 307 and the locking hole 306 in sequence along the longitudinal direction, which allows the wear-resistant liner 1 to be detachably assembled on the top of the liner body 2. At the same time, by simply turning the locking bolt 303 out of the locking hole 306 and the mating hole 307 in sequence, the mating slot 304 can be separated from the mating insert 305 in the vertical direction, thereby allowing the wear-resistant liner 1 to be removed from the top of the liner body 2. The assembly and disassembly of the wear-resistant liner 1 on the top of the liner body 2 is simple and easy to implement.

[0033] See Figures 1-6 As shown, the following optimizations were made to this scheme. Specifically, the mounting bolt holes 5 are countersunk bolt holes, and all mounting bolt parts 4 are countersunk bolt parts adapted to the mounting bolt holes 5. This allows the liner body 2 to be securely fixed to the inner cylinder of the rod mill by passing the mounting bolt parts 4 through the mounting bolt holes 5 and adding nuts at the rear end. Optionally, the upper part of the mounting bolt holes 5 are all countersunk portions 501, and the top of the mounting bolt parts 4 are all lower than the top of the countersunk portions 501, so that the top of the countersunk portions 501 has space for coaxial assembly and installation of the cover 6. Furthermore, the top of each countersunk portion 501 is coaxially and detachably fitted with a sealing cap 6 for sealing purposes, and the top surface of each sealing cap 6 is connected to a portion of the corresponding assembly connector 3. With this configuration, by coaxially engaging the sealing cap 6 with the countersunk portion 501 of the mounting bolt hole 5, the mating insert 305 of the assembly connector 3 can be assembled on the top of the liner body 2. Thus, by sealing the top of the mounting bolt hole 5 with the sealing cap 6, material can be prevented from entering the mounting bolt hole 5, achieving isolation and protection for the mounting bolt 4. Alternatively, the top of the inner circumference of the countersunk portion 501 is provided with internal threads, and the outer circumference of the sealing cap 6 is provided with external threads. The sealing cap 6 is coaxially and detachably connected to the top of the corresponding countersunk portion 501 through threaded engagement. This configuration facilitates quick assembly and disassembly of the sealing cap 6 and the countersunk portion 501 by screwing.

[0034] See Figures 1-4 As shown, the upper and lower parts of the wear-resistant liner 1 are a dovetail block and a rectangular block, respectively. This design, with the dovetail block at the top, can further increase the elevation of the rod when it rises. Optionally, both the mating hole 307 and the locking hole 306 are internally threaded through holes, and the locking bolts 303 are coaxially coupled with the corresponding mating holes 307 and locking holes 306 via threaded engagement. This design facilitates quick assembly and disassembly of the mating hole 307 and locking hole 306 by tightening. Optionally, the front end face of the wear-resistant liner 1 is coaxially provided with a hidden hole 301 at the position corresponding to the mating hole 307. The front end of the locking bolt 303 is inserted into the corresponding hidden hole 301, and the outer periphery of the front end of the locking bolt 303 does not contact the inner periphery of the hidden hole 301, so that the front end of the locking bolt 303 can be hidden and protected in the hidden hole 301. At the same time, it is also convenient to use an Allen wrench to tighten and loosen the locking bolt 303. It should be noted that when tightening the locking bolt 303, it is best to use a torque wrench. Furthermore, the outer periphery of the front end of the locking bolt 303 extending out of the mating hole 307 is slidably fitted with an anti-loosening washer 302, and the anti-loosening washer 302 is pressed into the hidden hole 301 by the front end of the corresponding locking bolt 303, so as to prevent the locking bolt 303 from loosening naturally.

[0035] Using the above structure, in practical application, multiple wear-resistant lining blocks 1 are installed on the surface of the liner body 2 using the combined connecting parts 3. The high-protruding wear-resistant lining blocks 1 on the surface of the liner body 2 can drive the bar to a higher elevation before it falls, thus stably increasing the crushing impact force of the bar. Since the upper and lower parts of the wear-resistant lining blocks 1 are dovetail blocks and rectangular blocks respectively, the dovetail design of the upper part of the wear-resistant lining blocks 1 further increases the elevation when driving the bar upward, contributing to further stable improvement of the bar's impact force. Specifically, when assembling the wear-resistant lining blocks 1 on the top surface of the liner body 2, the vertical sliding engagement of the fitting slot 304 and fitting insert 305 of the combined connecting parts 3, and the longitudinal passage of the locking bolt 303 through the fitting hole 307 and locking hole 306, allows the wear-resistant lining blocks 1 to be detachably assembled on the top of the liner body 2. Furthermore, simply tightening the locking bolt 303 to sequentially disengage it from the locking hole 306 and fitting hole 307 is sufficient to achieve the desired effect. The slot 304 is separated vertically from the insert block 305, allowing the wear-resistant liner 1 to be removed from the top of the liner body 2. The assembly and disassembly of the wear-resistant liner 1 on the top of the liner body 2 is simple and easy to implement. It facilitates the quick assembly of the wear-resistant liner 1 on the top of the liner body 2 for use, and also facilitates the subsequent replacement and maintenance after the wear-resistant liner 1 is removed from the top of the liner body 2. Furthermore, because the cover 6 is coaxially engaged with the countersunk portion 501 of the mounting bolt hole 5, the insert block 305 of the assembly connector 3 can be assembled on the top of the liner body 2. Then, by sealing the top of the mounting bolt hole 5 with the cover 6, material can be prevented from entering the mounting bolt hole 5, thus achieving isolation and protection of the mounting bolt 4 and helping to slow down the erosion of the mounting bolt 4 by corrosive materials. It should be noted that only multiple liner bodies 2 located in any axial longitudinal row in the inner cylinder of the rod mill need to be assembled with wear-resistant liner 1 to prevent too many wear-resistant liner 1 from affecting the crushing efficiency of the material.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
