Description
Technical Field
[0001] This utility model relates to the field of arc liner technology, specifically a novel magnetic arc liner device with extended lifespan. Background Technology
[0002] In grinding equipment commonly used in industries such as mining, building materials, and metallurgy, arc liners serve as core components, playing a crucial role in protecting the equipment cylinder, driving the movement of materials and grinding media, and assisting in the crushing and grinding of materials.
[0003] The traditional installation and connection structure of arc liners has obvious defects. Most traditional liners are directly bolted by drilling holes in the main body of the liner, lacking a special structural reinforcement design. This makes the installation part a weak point. When the equipment is running, the liner must withstand continuous vibration and impact and material scouring force. The weak installation part is prone to cracking and deformation. At the same time, the connection between the bolt and the liner is prone to loosening. This can lead to liner displacement, affecting grinding efficiency, or even liner falling off, causing equipment downtime. This not only increases maintenance costs but also seriously affects production continuity. In view of this, a new type of magnetic arc liner device with extended service life is proposed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a novel magnetic arc liner device with extended lifespan, solving the problem of poor service life of magnetic arc liners.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel magnetic arc liner device with extended lifespan, comprising a flat liner, wherein a lifting strip is fixedly installed on the upper surface of the flat liner; The flat liner is equipped with a protective mechanism, which includes a bolt hole boss and a bolt through hole. Two bolt hole bosses are fixedly installed in the inner wall of the flat liner plate, and two bolt through holes are respectively opened on the right surface of the two bolt hole bosses.
[0006] Preferably, the protective mechanism further includes bolts and washers, with two bolts threaded onto the inner surfaces of two bolt hole bosses respectively; Two washers are respectively placed on the outer surface of the two bolts.
[0007] Preferably, the protective mechanism further includes triangular air holes, which are respectively opened on the outer surface of the two gaskets.
[0008] Preferably, the protective mechanism further includes square air holes, which are respectively opened on the outer surface of the two gaskets.
[0009] Compared with the prior art, this utility model provides a novel magnetic arc liner device with extended lifespan, which has the following beneficial effects: 1. This new type of magnetic arc liner device with extended service life features bolt hole bosses that enhance the strength of the flat liner installation area. Bolts achieve tight threaded connections through bolt through holes, withstand vibration and impact to prevent component displacement, and gaskets disperse bolt pressure to prevent damage to the bosses. Triangular and square air holes work together to expel air and dust from gaps, assist in heat dissipation, reduce thread corrosion and local overheating aging, ensure long-term stability of the connection, reduce the risk of failure, and lay the foundation for reliable operation of the device.
[0010] 2. This new type of magnetic arc liner device with extended service life uses a flat liner as a high-strength magnetic conduction body to provide a stable carrier for the magnetic arc function and grinding. The lifting bar effectively drives the material and grinding media to rise, avoiding slippage and reducing direct scouring and wear of the flat liner. Each protective structure ensures the stable operation of the main components and reduces downtime maintenance caused by connection failures or local wear. While improving grinding and crushing efficiency, it significantly extends the service life of core components such as the flat liner and the overall device. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see Figure 1-4 This utility model provides a new technical solution: a new magnetic arc liner device with extended lifespan, including a flat liner 1, and a lifting strip 2 fixedly installed on the upper surface of the flat liner 1; The flat liner plate 1 is provided with a protective mechanism, which includes a bolt hole boss 3 and a bolt through hole 4. Two bolt hole bosses 3 are fixedly installed in the inner wall of the flat liner plate 1, and two bolt through holes 4 are respectively opened on the right surface of the two bolt hole bosses 3.
[0015] Furthermore, the protective mechanism also includes bolts 5 and washers 6, with the two bolts 5 threaded onto the inner surfaces of the two bolt hole bosses 3 respectively; Two washers 6 are respectively placed on the outer surface of the two bolts 5.
[0016] Furthermore, the protective mechanism also includes triangular vents 7, which are respectively opened on the outer surface of the two gaskets 6.
[0017] Furthermore, the protective mechanism also includes square air holes 8, which are respectively opened on the outer surface of the two gaskets 6.
[0018] Structural Explanation: Flat Liner 1: As the main load-bearing component of the device, it is the foundation for the installation of all structures. It must have high strength and magnetic conductivity. It is in direct contact with materials and grinding media, and withstands impact and wear. At the same time, it provides a magnetic conduction path for the magnetic arc function. The material is mostly wear-resistant alloy, which determines the service life of the device foundation. It is the core carrier that ensures the stability of the overall structure and the realization of functions.
[0019] Lifting bar 2: Fixed on the upper surface of the flat liner plate 1, it is raised. When the device rotates with the equipment, it can effectively drive the grinding media and materials to rise, avoid material slippage, and improve grinding or crushing efficiency. At the same time, it can reduce the direct scouring of the material on the upper surface of the flat liner plate 1, indirectly reduce the wear rate of the flat liner plate 1, and help extend the service life of the main components.
[0020] Bolt hole boss 3: There are 2 in total and they are fixedly installed in the inner wall of the flat backing plate 1. They provide a special installation structure for bolt connection. The protruding design can enhance the structural strength of the corresponding position of the inner wall of the flat backing plate 1, avoid cracking of the flat backing plate 1 due to excessive local stress during bolt installation, and accurately position the bolt installation position to ensure the stability of subsequent bolt connection and reduce the risk of failure of the connection part.
[0021] Bolt through holes 4: These are respectively opened on the right surface of the two bolt hole bosses 3. They are the installation channels for bolts 5. By pre-setting through holes, it can be ensured that bolts 5 can be accurately inserted into bolt hole bosses 3 and match the internal threads, avoiding damage to the components caused by on-site drilling. At the same time, it ensures the coaxiality of bolt installation, improves the tightness of bolt connection, and prevents component displacement caused by loose connection during use.
[0022] Bolt 5: Threaded connection on the inner surface of the two bolt hole bosses 3. It is the core connector for fixing the components. Through thread engagement, it stably connects the relevant components to the flat backing plate 1, withstands the vibration and impact loads during the operation of the device, and prevents the components from falling off or shifting. Its connection strength directly affects the stability and service life of the overall structure of the device.
[0023] Washers 6: These are respectively placed on the outer surface of the two bolts 5, located between the bolt head and the bolt hole boss 3. They can increase the contact area between the bolt 5 and the bolt hole boss 3, disperse the pressure when the bolt is tightened, prevent the bolt head from damaging the surface of the bolt hole boss 3, and fill the tiny gaps in the contact surface to enhance the sealing performance, reduce the entry of dust and impurities into the connection part, prevent thread corrosion, and extend the service life of the bolt connection.
[0024] Triangular vents 7: These are respectively opened on the outer surface of the two gaskets 6. They are venting structures on the gaskets. During the tightening of the bolts 5 or the operation of the device, the air between the gaskets and the bolt hole bosses 3 and the bolt heads can be discharged, preventing air from accumulating and forming a pressure difference that could cause the gaskets to fail to seal. At the same time, they can assist in heat dissipation when the device heats up, reducing the aging effect of excessive local temperature on the gasket material and ensuring the protective performance of the gaskets.
[0025] Square vents 8: Also located on the outer surface of the two gaskets 6, complementing the function of the triangular vents 7. The square structure of the vents has a larger ventilation area, which can further improve the air circulation and heat dissipation efficiency of the gasket area. Especially in scenarios where the device operates under high load for a long time and generates a lot of heat, it can more effectively reduce the temperature of the connection part. At the same time, it can also help to remove dust that enters the gap and reduce the impact of impurity accumulation on the connection stability.
[0026] This novel magnetic arc liner device with extended lifespan, when the external equipment is started, the flat liner 1, as the main body of the device, begins to rotate synchronously with the rotating mechanism of the external equipment. Its rotation direction is consistent with that of the external equipment, driving the entire device into motion. As the flat liner 1 rotates, the lifting bar 2 fixed to its surface moves synchronously. When rotating to the lower position, the protruding structure of the lifting bar 2 contacts the material and grinding media, using friction and thrust to drive the material and grinding media upwards along the surface of the flat liner 1. When rotating to the upper position, the material and grinding media fall under gravity, completing one cycle of lifting and falling. During this process, the material is ground or crushed. During the rotation of the entire device driven by the flat liner 1, the threaded connection between the bolt 5 and the bolt hole boss 3 withstands vibration and... Under impact loads, the gasket 6 remains in contact with the head of the bolt 5 and the bolt hole boss 3, continuously dispersing pressure and sealing gaps. Simultaneously, the heat generated during device operation raises the temperature of the connection area. The triangular vent 7 and square vent 8 move synchronously with the gasket 6, carrying away heat through air circulation to prevent localized overheating. Furthermore, if dust generated during rotation enters the gap between the gasket and the component, it will be discharged through the triangular vent 7 and square vent 8, reducing impurity accumulation and ensuring stable operation of the connection area. As the external equipment continues to operate, components such as the flat liner 1 and lifting bar 2 repeatedly undergo the above-mentioned movement process. The bolt hole boss 3, bolt 5, gasket 6, and vents, among other protective components, always play their roles, ensuring that the device maintains structural stability during long-term operation and extending its overall service life.
