TECHNICAL FIELD
[0001] The present application belongs to the technical field of compensators, in particular to a compensator skin and a quick-mounting non-metallic compensator. BACKGROUND
[0002] Non-metallic compensators are widely used in flue gas and pulverized coal pipeline systems to absorb the displacement caused by thermal expansion and contraction. The non-metallic compensator is a flexible connecting element, and its working principle is to eliminate the stress in the pipeline or equipment system by absorbing displacement. The ring belt (also known as the skin) is a key component that realizes the displacement amount through its flexibility. The ring belt is divided into integral and combined types.
[0003] The ring belt is divided into two structural types, integral and combined. The ring belt is fastened by a bolted pressing plate, which is then pressed against the frame to form a seal. According to industry standards, the bolt spacing is not greater than 150mm in principle. The advantages of this structure are easy to process and low cost. The disadvantages are that a large number of bolts are used, and the ring belt is assembled by manual operation, which is labor-intensive. When replacing the ring belt during the later use of the product, the bolts are often corroded and rusted due to the high-temperature corrosive environment, making them difficult to disassemble. Most of them can only be cut off one by one using a gas cutter or an angle grinder. Since the ring belt is difficult to position during installation and use, the bolt spacing in the industry is usually 100mm. Each non-metallic compensator has hundreds of bolts, and the non-metallic compensator is usually arranged in high-altitude large pipelines. The manual disassembly of the bolts one by one is labor-intensive, especially when the pipeline is arranged overhead, a scaffold needs to be erected, resulting in a long operation time, high cost, and a high risk of high-altitude work, which poses a safety hazard. SUMMARY
[0004] To solve the problem of the current skin body needing a large number of and dense bolts for fixation due to positioning difficulties, resulting in a long time and high risk of high-altitude work during replacement due to the cumbersome disassembly, the present application provides a compensator skin and a quick-mounting non-metallic compensator that facilitates positioning of the skin body and increases the fastening spacing to reduce the long operation time during replacement.
[0005] The present application is achieved by the following technical solutions: A compensator skin, comprising a skin body, the skin body being a flexible profile, the cross section of the flexible profile comprising a flexible plane body, and the upper and lower surfaces on both sides of the flexible plane body being respectively provided with positioning protruding ribs.
[0006] The skin body uses the positioning protruding ribs as the pressing position during installation, which helps to reduce positioning difficulties and increase the fastening spacing to reduce the number of fasteners used. When the skin body needs to be replaced, the disassembly time and safety risk of the fasteners can be reduced. The positioning protruding ribs can also assist in quickly locating the installation position.
[0007] Further improvement of the present application is that the flexible plane body and the positioning raised rib are integrated and formed by high-temperature vulcanization. The positioning raised rib is integrated on the flexible plane body by high-temperature vulcanization, which not only improves the overall structural strength, but also has beneficial elasticity and durability, and can better adapt to the displacement and vibration performance of the compensator.
[0008] Further improvement of the present application is that the flexible plane body and the positioning raised rib are integrated and formed by high-temperature vulcanization. The positioning raised rib is integrated on the flexible plane body by high-temperature vulcanization, which not only improves the overall structural strength, but also has beneficial elasticity and durability, and can better adapt to the displacement and vibration performance of the compensator.
[0009] Further improvement of the present application is that the cross section of the positioning raised rib is one of fan-shaped, spherical, square, trapezoidal or triangular. Different shapes of cross section are selected to optimize the applicability of the component.
[0010] A quick-mounting non-metal compensator includes a framework, a pressing plate and a compensator skin. The skin body is pressed between the framework and the pressing plate by fasteners. The framework and the pressing plate are respectively provided with groove one and groove two which can be matched with the positioning raised rib.
[0011] The flexible plane body is matched with the groove on the pressing plate and the framework through the positioning raised rib on the surface of the flexible plane body, which forms the centering and alignment function during assembly. At the same time, the positioning raised rib is sealed with the groove, and the contact area of the pressing is increased, thereby providing a physical structure basis for reducing the use of fasteners and expanding the fastener spacing, reducing the labor time and workload during subsequent disassembly. Due to the shortening of the operation time, the risk coefficient of high-altitude operation is reduced.
[0012] Further improvement of the present application is that the framework is provided with a raised section one, and the raised section one forms a groove one on the side surface close to the positioning raised rib. The raised section one optimizes the structural strength of the framework, and the inner side surface forms the groove one matched with the positioning raised rib, thereby increasing the durability of the component.
[0013] Further improvement of the present application is that the pressing plate is provided with a raised section two, and the raised section two forms a groove two on the side surface close to the positioning raised rib. The raised section two optimizes the structural strength of the pressing plate, and the inner side surface forms the groove two matched with the positioning raised rib, thereby increasing the durability of the component.
[0014] The further improvement of the present application is that the fastener comprises a fastening bolt and a fastening nut, the fastening bolt sequentially penetrates the pressing plate, the skin body and the framework, and the fastening nut is threadedly connected on the fastening bolt. After the positioning protruding ribs preliminarily fit with the groove regions of the pressing plate and the framework, the fastening nut is pressed tightly by penetrating the fastening bolt, so that the loosening of the skin body is prevented.
[0015] The further improvement of the present application is that the fastener further comprises two gaskets sleeved on the fastening bolt, and the two gaskets are arranged on the outer sides of the framework and the pressing plate. The gasket is a duckbill gasket, and the uneven force of the fastening bolt and the fastening nut when pressing the components in contact can be compensated by using the gasket, so that the sealing performance of the compensator is ensured.
[0016] From the above technical solution, it can be seen that the beneficial effects of the present application are that the skin body is pressed in the installation position by the positioning protruding ribs, which helps to reduce the positioning difficulty, and the fastening interval can be increased to reduce the number of fasteners used, and when the skin body needs to be replaced, the disassembly time and safety risk of the fastener can be reduced; and the positioning protruding ribs can assist in quickly locating the installation position.

[0030] In order to make the purpose, features and advantages of the present application more obvious and easy to understand, the technical solutions in the present application will be described clearly and completely below in combination with the drawings in the specific embodiments. Obviously, the following described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present patent, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present patent.
[0031] As shown in Figures 1-11 The present application discloses a compensator skin, which comprises a skin body 2, wherein the skin body 2 is a flexible profile, and the cross section of the flexible profile comprises a flexible plane body 202, and the upper and lower surfaces on both sides of the flexible plane body 202 are respectively provided with positioning raised ribs 201.
[0032] The skin body 2 serves as a pressing position through the positioning raised ribs 201 during installation, which helps to reduce positioning difficulty, and can increase fastening spacing to reduce the number of fasteners 4 used, and when the skin body 2 needs to be replaced, the dismounting time and safety risk of the fasteners 4 can be reduced; meanwhile, the positioning raised ribs 201 can assist in quickly locating the installation position.
[0033] The flexible plane body 202 and the positioning raised rib 201 are integrated structures and are integrally formed by high-temperature vulcanization. The positioning raised rib 201 is integrally formed on the flexible plane body 202 through high-temperature vulcanization, which not only improves the overall structural strength, but also has beneficial elasticity and durability, and can better adapt to the displacement and vibration performance of the compensator.
[0034] The flexible plane body 202 and the positioning raised rib 201 are split structures and are formed by gluing or sewing. The split manufacturing structure optimizes the process flexibility, and can realize different material selection and application of the flexible plane body 202 and the positioning raised rib 201 according to actual needs, while reducing the mold cost and manufacturing difficulty.
[0035] The cross section of the positioning raised rib 201 is one of a fan shape, a spherical shape, a square shape, a trapezoidal shape or a triangular shape. Different shapes of cross sections are selected to optimize the applicability of the component.
[0036] A quick-mounting non-metallic compensator includes a framework 1, a pressing plate 3 and a compensator skin; the skin body 2 is pressed between the framework 1 and the pressing plate 3 by a fastener 4, and the framework 1 and the pressing plate 3 are respectively provided with a groove one 102 and a groove two 302 which can be matched with the positioning raised rib 201.
[0037] The flexible plane body 202 is matched with the groove on the pressing plate 3 and the framework 1 through the positioning raised rib 201 on the surface thereof, forming the centering and alignment function during assembly; at the same time, the positioning raised rib 201 is sealingly matched with the groove, and the contact area of the pressing is increased, thereby providing a physical structure basis for reducing the use of the fastener 4 and expanding the fastener 4 spacing, reducing the labor time and workload during subsequent disassembly, and reducing the risk coefficient of high-altitude operation due to the shortening of the operation time.
[0038] The framework 1 is provided with a raised section one 101, and the raised section one 101 forms a groove one 102 on the side surface close to the positioning raised rib 201. The raised section one 101 optimizes the structural strength of the framework 1, and at the same time, the inner side surface thereof forms the groove one 102 matched with the positioning raised rib 201, thereby increasing the durability of the component.
[0039] The pressing plate 3 is provided with a raised section two 301, and the raised section two 301 forms a groove two 302 on the side surface close to the positioning raised rib 201. The raised section two 301 optimizes the structural strength of the pressing plate 3, and at the same time, the inner side surface thereof forms the groove two 302 matched with the positioning raised rib 201, thereby increasing the durability of the component.
[0040] The fastener 4 comprises a fastening bolt 401 and a fastening nut 402, the fastening bolt 401 is sequentially penetrated through the pressing plate 3, the skin body 2 and the framework 1, and the fastening nut 402 is threadedly connected on the fastening bolt 401. After the positioning protruding ribs 201 are preliminarily matched with the groove regions of the pressing plate 3 and the framework 1 respectively, the fastening bolt 401 is penetrated and matched with the fastening nut 402 to be pressed tightly, so that the loosening of the skin body 2 is prevented.
[0041] The fastener 4 further comprises two gaskets 403 sleeved on the fastening bolt 401, and the two gaskets 403 are arranged on the outer sides of the framework 1 and the pressing plate 3 respectively. The gasket 403 is a duckbill-shaped gasket 403, and through the use of the gasket 403, the uneven force of the fastening bolt 401 and the fastening nut 402 when contacting the components to be pressed tightly can be compensated, so that the sealing performance of the compensator is guaranteed.
[0042] Compared with the thickness of the traditional and same steel material components, the bending resistance of the pressing plate 3 and the framework 1 in the device is obviously enhanced, and the bending resistance is increased by 4-5 times through testing. The cooperation of the groove and the positioning protruding ribs 201 shares the insufficient performance of the fastener 4 for pressing the skin body 2 to prevent movement. The number of fasteners 4 used per two meters is about 40 sets in the traditional operation, and the number of fasteners 4 used per two meters is reduced to 10 sets after the product is used.
[0043] Taking a flue commonly used specification 4000*9000mm non-metallic compensator as an example, the number of bolts used by the conventional structure pressing plate 3 is 540 sets; if the fast-assembly non-metallic compensator is used, the number of bolts used is 130 sets; the assembly and removal efficiency is increased by 4 times.
[0044] In summary, the use principle of the device is that the positioning protruding ribs 201 are embeddedly matched with the groove regions on the pressing plate 3 and the framework 1 respectively, so that the insufficient coverage of the fastening bolt 401 and the fastening nut 402 for pressing the components is effectively shared, the quality guarantee for reducing the use of fasteners 4 is provided, and the stress of the area pressing effect on the components is further optimized through the cooperation of the gaskets 403.
[0045] The skin of the compensator and the fast-assembly non-metallic compensator disclosed by the application is provided with positioning protruding ribs, which are used as pressing positions during installation, so that positioning difficulty is reduced, the fastening interval is increased, the number of fasteners used is reduced, the disassembly time and safety risk of the fasteners are reduced when the skin body needs to be replaced, and the positioning protruding ribs can assist in quickly locating the installation position.
