Abstract
Description
Technical Field
[0001] This utility model relates to the field of wear-resistant rubber lining technology, specifically to a corrosion-resistant and wear-resistant rubber lining with wear warning function. Background Technology
[0002] Rubber lining is an important anti-corrosion and wear-resistant protective component, widely used in many industrial fields such as chemical, mining, power, and water conservancy. It is mainly used for the inner wall protection of various pipelines, reaction vessels, storage tanks and other equipment to resist equipment wear caused by media corrosion and material erosion, extend equipment service life and ensure production safety.
[0003] However, existing rubber-lined layers present several problems in practical applications that urgently need to be addressed. On one hand, traditional rubber-lined layers are mostly integral structures. When local wear or damage occurs, the entire layer needs to be disassembled and replaced. This process is not only cumbersome and time-consuming, but also leads to prolonged equipment downtime, significantly increasing maintenance costs and production losses. While some segmented rubber-lined layers solve the problem of overall replacement, their connection structures are often poorly designed. Either the mating precision is poor, leading to gaps that allow corrosive media to penetrate, or the connection strength is insufficient, making them prone to loosening and detachment under material erosion and equipment vibration, thus affecting the protective effect.
[0004] On the other hand, existing rubber linings lack effective means of monitoring wear conditions. Since the wear process of the rubber lining typically occurs inside the equipment, it is difficult to observe directly with the naked eye, and operators cannot promptly grasp its degree of wear. Often, problems are only discovered when the rubber lining has completely worn away, leading to corrosion, leaks, or abnormal material conveying in the equipment itself. By then, equipment damage, material waste, and even potential safety accidents have already occurred. Furthermore, some rubber linings focus only on single properties such as corrosion resistance or wear resistance, failing to achieve synergistic optimization of both. Under harsh operating conditions of strong corrosion and high erosion, their service life is generally short, requiring frequent replacement, further increasing operating costs. Utility Model Content
[0005] Technical problems to be solved
[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a corrosion-resistant and wear-resistant rubber lining with wear warning function, which can effectively solve the problems in the existing technology.
[0007] Technical solution
[0008] This utility model provides a corrosion-resistant and wear-resistant rubber lining with wear warning function, including two sets of rubber linings. The two ends of the two sets of rubber linings are respectively fixed with connecting pieces and connecting heads. The two sets of rubber linings are joined together to form a ring structure. A groove is opened on the outside of each set of rubber linings, and an induction coil is sleeved in the groove.
[0009] Furthermore, the connecting piece and the connector are respectively provided with a mating hole and a round hole in the middle, and the connecting piece and the connector are fixedly connected by locking bolts.
[0010] Furthermore, both the mating hole and the circular hole are provided in two sets.
[0011] Furthermore, the connecting piece and the connector are mated together, and the sum of their thicknesses is the same as the thickness of the middle part of the rubber lining layer.
[0012] Furthermore, the inner wall of the rubber lining layer is coated with a wear-resistant coating.
[0013] Beneficial effects
[0014] In this invention, the corrosion-resistant and wear-resistant rubber lining with wear warning function uses an induction coil installed inside the outer groove of the lining to monitor the wear level of the lining in real time using the electromagnetic induction characteristics of the induction coil. When the thickness of the lining decreases due to wear, the inductance and other parameters of the induction coil will change accordingly. These changes can be captured by the matching detection equipment, which will issue an early warning signal. This allows operators to promptly grasp the wear status of the lining and arrange maintenance and replacement work in advance, effectively avoiding safety accidents such as equipment corrosion and leakage caused by lining failure, and significantly improving the safety and reliability of equipment operation.
[0015] In this device, two sets of rubber-lined layers are joined front to back to form a ring structure. Compared to traditional integral rubber-lined layers, when local wear or damage occurs, only the damaged rubber-lined layer needs to be removed and replaced, eliminating the need to replace the entire rubber-lined layer. This significantly simplifies the maintenance process, shortens equipment downtime, and reduces maintenance costs and production losses. Furthermore, the two sets of rubber-lined layers are joined via connecting plates and connectors, resulting in a simple and reliable connection structure that facilitates quick disassembly and installation, further improving maintenance efficiency.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0023] The present invention will be further described below with reference to the embodiments.
[0024] Example: A corrosion-resistant and wear-resistant rubber lining with wear warning function, see attached figure. Figure 1 -Appendix Figure 4 It includes two sets of rubber lining layers 1, with connecting pieces 12 and connectors 14 fixed at both ends of the two sets of rubber lining layers 1 respectively. The two sets of rubber lining layers 1 are joined together to form a ring structure, and a groove 11 is provided on the outside of each set of rubber lining layers 1. An induction coil 2 is sleeved inside the groove 11.
[0025] Both the connecting piece 12 and the connector 14 have mating holes 121 and 141 respectively in their middle portions. The connecting piece 12 and the connector 14 are fixedly connected by locking bolts 13. The use of two sets of rubber lining layers 1 forming a ring structure by mating them together front and back is a significant improvement over traditional integral rubber lining layers 1. When local wear or damage occurs, only the damaged set of rubber lining layers 1 needs to be removed and replaced, eliminating the need to replace the entire rubber lining layer 1. This greatly simplifies the maintenance process, shortens equipment downtime, and reduces maintenance costs and production losses. Furthermore, the two sets of rubber lining layers 1 are mated together via the connecting piece 12 and the connector 14, resulting in a simple and reliable connection structure that facilitates quick disassembly and installation, further improving maintenance efficiency.
[0026] The connecting piece 12 and the connector 14 each have two sets of mating holes 121 and round holes 141 in their middle portions, which are fixed together by locking bolts 13. The design of the two sets of holes makes the force at the connection point more even, improving the stability and strength of the connection structure and effectively preventing the connection from loosening and falling off under the action of material scouring and equipment vibration. At the same time, the sum of the thicknesses of the connecting piece 12 and the connector 14 after mating is the same as the thickness of the middle part of the rubber lining layer 1, ensuring the flatness of the surface of the rubber lining layer 1 and avoiding material retention and additional scouring and wear caused by steps at the connection point, thus ensuring the overall protective effect and service life of the rubber lining layer 1.
[0027] An induction coil 2 is pre-installed inside the rubber lining layer 1. When the wear-resistant inner layer of the rubber lining layer 1 is worn through, corrosive or conductive media will come into contact with or change the state of this conductive layer. The electromagnetic induction characteristics of the induction coil 2 are used to monitor the wear degree of the rubber lining layer 1 in real time. When the thickness of the rubber lining layer 1 decreases due to wear, the inductance and other parameters of the induction coil 2 will change accordingly. These changes can be captured by the matching detection equipment and an early warning signal can be issued. This allows operators to grasp the wear state of the rubber lining layer 1 in a timely manner, arrange maintenance and replacement work in advance, effectively avoid safety accidents such as equipment corrosion and leakage caused by the failure of the rubber lining layer 1, and significantly improve the safety and reliability of equipment operation.
[0028] Two sets of mating holes 121 and 141 are provided; the connecting piece 12 and the connector 14 are mated together, and the sum of their thicknesses is the same as the thickness of the middle part of the rubber lining layer 1; the inner wall of the rubber lining layer 1 is coated with a wear-resistant coating; the wear-resistant coating on the inner wall of the rubber lining layer 1, combined with the corrosion resistance of the rubber lining layer 1 itself, forms a dual protection structure of "corrosion resistance in the rubber lining layer 1 + wear resistance of the wear-resistant coating", which significantly improves the overall corrosion resistance and wear resistance of the rubber lining layer 1, and can better adapt to the harsh working conditions of strong corrosion and high erosion in chemical, mining and other fields. This dual protection design effectively slows down the wear rate of materials on the rubber lining layer 1, extends the service life of the rubber lining layer 1, reduces the frequency of replacement, and further reduces the cost of use.
[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
