Description

Technical Field

[0001] This utility model relates to the field of wear-resistant lining technology, specifically a new type of wear-resistant lining based on the foundry industry. Background Technology

[0002] In heavy industries such as mining, metallurgy, building materials, and power, wear-resistant liners serve as critical equipment protective components, enduring the combined effects of material impact, friction, and corrosive media over extended periods. Traditional wear-resistant liners primarily utilize a single material structure, requiring periodic replacement of the entire liner when localized wear occurs after prolonged use, which is energy-inefficient. To address these drawbacks, some existing wear-resistant liner structures design the liner sections in direct contact with materials as modular, assembly-type structures, allowing for replacement of only worn sections.

[0003] While wear-resistant liners can save costs for businesses to some extent, their structure still presents some unresolved issues in actual use. Specifically, bolt connections are primarily used in the splicing process. Because the bolts inserted into the inner surface of the liner are in constant contact with the material, mismatches in the bolt threads can easily occur under impact forces. This often presents businesses with a dilemma: replacing the entire liner structure would not only result in significant material waste but also increase equipment downtime, impacting production efficiency. Re-threading only in specific areas would be cumbersome and could potentially compromise the liner's structural strength and overall performance due to secondary processing.

[0004] In addition, the existing wear-resistant liners lack an effective real-time monitoring mechanism between the liners and the machine body, making it impossible to dynamically track changes in the liner thickness and stress state. This makes it difficult for companies to grasp the actual wear of the liners in a timely manner. When the liners are excessively worn or the stress is abnormal, there is often no early warning, resulting in a high frequency of subsequent unplanned downtime maintenance, which further increases the company's operating costs and production risks. Utility Model Content

[0005] The purpose of this invention is to provide a novel wear-resistant liner for the foundry industry, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel wear-resistant liner for the foundry industry, comprising: an equipment housing, a liner unit installed on the inner wall of the equipment housing, a monitoring unit provided between the liner unit and the equipment housing, the liner unit comprising: an integral liner, the integral liner installed on the inner wall of the equipment housing, multiple segmented liners installed on the inner wall of the integral liner, a pair of insertion holes opened at the end of each segmented liner near the integral liner, the insertion holes penetrating the inner surface of the integral liner, a threaded post provided inside the insertion hole, a pair of first bolts inserted into the inner surface of each segmented liner, the first bolts penetrating a portion of the segmented liner and threadedly connected to the threaded post, a second bolt inserted into the surface of the equipment housing, the second bolt penetrating a portion of both the equipment housing and the integral liner and threadedly connected to the threaded post.

[0007] Preferably, the monitoring unit includes: a plurality of grooves, all of which are formed on the inner wall of the device housing, and a monitoring component is installed inside the grooves, the monitoring component being connected to the grooves via a mounting unit.

[0008] Preferably, the mounting unit includes: a PTFE buffer frame, the PTFE buffer frame being fitted to the inner wall of the groove, the PTFE buffer frame being connected to the equipment housing by screws, and the monitoring component being fixedly connected to the PTFE buffer frame.

[0009] Preferably, the interior of the PTFE buffer frame has multiple micropores.

[0010] Preferably, the inner wall of the insertion hole is provided with a pair of sliding grooves, and a sliding strip is slidably engaged inside the sliding grooves. The sliding strip is fixedly connected to the contact surface of the threaded post.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This novel wear-resistant liner based on the foundry industry has the following advantages over traditional technology: Through the cooperation between the equipment housing and the liner unit, the integral liner 2 and the segmented liner 3 set on the inner surface of the equipment housing 1 have excellent wear resistance and impact resistance, which can effectively protect the inner wall of the equipment housing from wear and damage. After long-term use, if the segmented liner is severely worn and needs to be replaced, it is only necessary to turn the first bolt counterclockwise to separate it from the threaded post, so that the severely worn segmented liner can be replaced without replacing the integral liner. This method is more energy-saving. When the first bolt is affected by the impact force due to contact with the material, resulting in a decrease in the thread matching degree between it and the threaded post, the second bolt can be turned counterclockwise to separate it from the threaded post. In this way, the threaded post with reduced thread matching degree and the first bolt can be replaced without replacing the integral liner or opening additional threaded holes on its surface, and the structural strength and overall performance of the liner will not be significantly damaged. Through the cooperation between the equipment housing, liner unit and monitoring unit, the monitoring component installed inside the groove on the inner wall of the equipment housing can monitor the thickness and stress state of the overall liner and segmented liner in real time. When the wear of the overall liner reaches the threshold or an abnormal stress occurs, the monitoring component will automatically trigger an early warning signal to the external system, so that external personnel can intuitively understand the actual situation of the liner unit, thereby reducing the frequency of unplanned downtime maintenance and facilitating the reduction of the company's operating costs and production risks. Through the cooperation between the equipment housing, liner unit, monitoring unit, and installation unit, the PTFE buffer frame set between the monitoring component and the groove can buffer the impact force during equipment operation to a certain extent, extend the service life of the monitoring component, and avoid more frequent maintenance and repair.

[0015] 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.

[0016] Please see Figures 1-3This utility model provides a technical solution: a novel wear-resistant liner for the foundry industry, comprising: an equipment housing 1, a liner unit installed on the inner wall of the equipment housing 1, a monitoring unit provided between the liner unit and the equipment housing 1, the liner unit comprising: an integral liner 2, the integral liner 2 installed on the inner wall of the equipment housing 1, multiple segmented liner plates 3 installed on the inner wall of the integral liner 2, a pair of insertion holes 4 opened at the end of the segmented liner plates 3 near the integral liner plate 2, the insertion holes 4 penetrating the inner surface of the integral liner plate 2, a threaded post 5 provided inside the insertion holes 4, a pair of first bolts 8 inserted into the inner surface of the segmented liner plates 3, the first bolts 8 penetrating a part of the segmented liner plates 3 and threadedly connected to the threaded post 5, a second bolt 9 inserted into the surface of the equipment housing 1, the second bolt 9 penetrating a part of the equipment housing 1 and the integral liner plate 2 and threadedly connected to the threaded post 5.

[0017] In the specific implementation process, it is worth noting that the materials used for the integral liner 2 and the segmented liner 3, which have excellent wear resistance and impact resistance, are not only processed through casting to make the internal structure uniform and dense with high surface hardness, but also can have special wear-resistant alloying elements, such as tungsten carbide and chromium carbide, added to further improve their wear resistance and extend their service life. The first bolt 8 and the second bolt 9 are made of high-strength, fatigue-resistant bolt materials, and the surface is treated with anti-rust treatment, such as zinc plating or Dacromet coating, to prevent the connection strength from being reduced due to corrosion during long-term use. The material of the threaded post 5 is matched with the bolt, and its thread precision is strictly controlled to ensure that the threads can fit tightly with the bolt threads and guarantee the stability of the connection.

[0018] Furthermore, the monitoring unit includes: multiple grooves 10, all of which are formed on the inner wall of the equipment housing 1. A monitoring component 11 is installed inside the groove 10, and the monitoring component 11 is connected to the groove 10 through a mounting unit.

[0019] In the specific implementation process, it is worth noting that the shape and size of the groove 10 are precisely designed according to the shape of the monitoring component 11 to ensure that the monitoring component 11 can be stably installed in the groove 10. The RFID chip built into the monitoring component 11 has a unique identification function, which can accurately identify the location and related information of each monitoring point, facilitating subsequent data management and analysis. The thin-film pressure sensor is made of high-precision and high-sensitivity materials, which can accurately sense the pressure changes borne by the liner. Its measurement range and accuracy are selected and calibrated according to the actual working conditions to ensure that it can accurately reflect the stress state of the liner.

[0020] Furthermore, the installation unit includes: a PTFE buffer frame 12, which is fitted to the inner wall of the groove 10, and is connected to the equipment housing 1 by screws 13. The monitoring component 11 is fixedly connected to the PTFE buffer frame 12.

[0021] In the specific implementation process, it is worth noting that the PTFE material used in the PTFE buffer frame 12 has excellent chemical stability, high temperature resistance and low coefficient of friction. The monitoring component 11 and the PTFE buffer frame 12 are fixed by a reliable method such as adhesive bonding to ensure that there will be no relative displacement when subjected to impact force, thus ensuring the accuracy of the monitoring data.

[0022] Furthermore, the interior of the PTFE buffer frame 12 is provided with multiple micropores 14.

[0023] In the specific implementation process, it is worth noting that the micropore 14 structure further enhances the buffering performance. When subjected to impact force, the micropore 14 can undergo elastic deformation to absorb and disperse some of the energy. The presence of the micropore 14 can not only improve the buffering performance of the PTFE buffer frame 12, but also reduce the weight of the material and reduce the overall load of the equipment.

[0024] Furthermore, a pair of sliding grooves 6 are provided on the inner wall of the insertion hole 4, and a sliding strip 7 is slidably engaged inside the sliding groove 6. The sliding strip 7 is fixedly connected to the contact surface of the threaded post 5.

[0025] In the specific implementation process, it is worth noting that the size and shape of the slide groove 6 match the slide bar 7 to ensure that the slide bar 7 can slide smoothly in the slide groove 6, while also ensuring that there is sufficient friction between the slide bar 7 and the slide groove 6 to prevent the slide bar 7 from sliding on its own during equipment operation. This makes it easier to position and fix the threaded post 5 during installation and disassembly, and also enhances the connection stability between the threaded post 5 and the insertion hole 4, thereby improving the structural strength of the entire liner unit.

[0026] Working principle: Wear-resistant protection principle: During equipment operation, the integral liner 2 and the segmented liner 3 installed on the inner surface of the equipment shell 1 work together. The integral liner 2 provides basic large-area protection for the inner wall of the equipment, while the segmented liner 3 provides enhanced protection for local wear-prone areas. Both are made of materials with excellent wear resistance and impact resistance. This material is processed through casting to make its internal structure uniform and dense with high surface hardness, which can effectively resist the wear and impact generated when materials flow and collide inside the equipment, thereby protecting the inner wall of the equipment shell 1, preventing it from being damaged, and extending the service life of the equipment.

[0027] The principle behind easy replacement of segmented lining plates: After prolonged use, when the local segmented liner 3 becomes severely worn due to frequent material impacts, it can be easily replaced. Simply turn the first bolt 8 counterclockwise, and the threaded connection between the first bolt 8 and the threaded post 5 gradually separates. Once the first bolt 8 is completely disengaged from the threaded post 5, the severely worn segmented liner 3 can be removed from the equipment, replaced with a new segmented liner 3, and the first bolt 8 can be re-tightened to the threaded post 5. The replacement process does not require disassembly or replacement of the entire liner 2, greatly saving replacement time and energy consumption. If the first bolt... 8. Due to long-term contact with materials and impact, the thread matching degree between the threaded post 5 and the threaded post 5 is reduced, resulting in problems such as stripping. Further processing can be carried out. At this time, the second bolt 9 is rotated counterclockwise to separate the second bolt 9 from the threaded post 5. Then, the threaded post 5 with reduced thread matching degree and the first bolt 8 are removed as a whole and replaced. This design does not require replacing the entire liner 2, nor does it require additional threaded holes on its surface. It will not cause significant damage to the structural strength and overall performance of the liner, ensuring that the liner can still perform its wear-resistant protection function normally after the parts are replaced.

[0028] Real-time monitoring and early warning principle: The monitoring component 11, installed inside the groove 10 on the inner wall of the equipment housing 1, is responsible for real-time monitoring. The monitoring component 11 is equipped with a built-in RFID chip and a thin-film pressure sensor, which can continuously and accurately measure the thickness and stress state of the overall liner 2 and the segmented liner 3. The measured data is transmitted to the internal processing system of the monitoring component 11 in real time. The processing system analyzes and judges the data. When the wear of the overall liner 2 reaches a preset threshold, or when an abnormal stress condition is detected in the liner, the monitoring component 11 will immediately and automatically trigger an early warning signal to an external system. The external system can be the equipment control center or the terminal equipment of the operator. The early warning signal can be presented in various forms such as audible and visual alarms, SMS notifications, and system pop-ups. After receiving the early warning signal, the operator can intuitively understand the actual situation of the liner unit and promptly arrange for the inspection and maintenance of the liner, thereby reducing the frequency of unplanned downtime maintenance, avoiding sudden equipment failure due to excessive wear or damage to the liner, and helping to reduce the company's operating costs and production risks.

[0029] Impact buffer protection principle: The PTFE buffer frame 12, positioned between the monitoring component 11 and the groove 10, plays a crucial role in buffering and protecting the equipment. During operation, the flow and collision of materials within the equipment generate impact forces, which are transmitted to the equipment housing 1 and the monitoring component 11 mounted thereon. The PTFE buffer frame 12, made of PTFE material with buffering properties, absorbs and disperses some of the impact force when it acts on the monitoring component 11, thereby reducing the direct impact of the impact force on the monitoring component 11. Through this buffering protection mechanism, the risk of damage to the monitoring component 11 due to frequent impacts can be effectively reduced, extending its service life, reducing the frequency of maintenance and repairs, and ensuring that the monitoring component 11 can operate stably for a long period, providing reliable monitoring support for the normal operation of the equipment.
