Description

Technical Field

[0001] This utility model relates to the field of pipeline thermal insulation technology, and in particular to a pipeline thermal insulation protection structure with an embedded aerogel core. Background Technology

[0002] In industrial sectors such as petroleum, chemical, and district heating or refrigeration, pipelines are widely used to transport high-temperature or low-temperature media. In order to reduce heat loss or cold dissipation during the transportation process and to ensure system operating efficiency and safety, a heat insulation layer must be laid on the outer wall of the pipeline.

[0003] To protect the insulation layer from mechanical damage, rainwater erosion, or chemical corrosion from the external environment and extend its service life, a rigid protective shell needs to be installed on the outermost layer of the insulation layer. Industrial pipeline systems are very long, and the protective shell cannot be manufactured as a continuous integral structure. In actual construction, the protective shell must be manufactured in sections and then assembled and spliced ​​on site around the insulation layer.

[0004] When splicing existing protective shell sections, simple overlapping, conventional bolts, or clips are often used for fixing. These connection methods can lead to problems such as inconvenient alignment and insufficient connection during on-site installation. Especially when flexible adjustments are needed based on the actual length of the insulation layer, the existing splicing structure lacks a mechanism that can both quickly lock and ensure connection reliability, resulting in low installation efficiency and insufficient connection stability between protective shells.

[0005] Therefore, this utility model proposes a pipe thermal insulation protection structure with an embedded aerogel core to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology of pipe thermal insulation protection structure with built-in aerogel core, the thermal insulation material is prone to axial displacement due to vibration or gravity, resulting in thermal insulation blind spots. In addition, the thermal insulation material is easily damaged by vibration and the total length of the protective shell is difficult to adjust flexibly according to the working conditions. The present invention aims to provide a pipe thermal insulation protection structure with built-in aerogel core that has been improved and can effectively solve the above problems.

[0007] This utility model provides a pipe thermal insulation protection structure with built-in aerogel core, including: an inner lining, thermal insulation cotton, buffer cotton and protective shell, as well as a splicing mechanism. The thermal insulation cotton is wrapped around the outer wall of the inner lining, the buffer cotton is wrapped around the outer wall of the thermal insulation cotton, and the protective shell is wrapped around the outer wall of the buffer cotton.

[0008] The splicing mechanism is used to connect adjacent protective shells. The splicing mechanism includes a first connecting block and a second connecting block. The first connecting block is fixedly connected to the end of the protective shell, and the second connecting block is fixedly connected to the end of another adjacent protective shell. A limiting post is provided at the rear end of the first connecting block, and a slot for accommodating the limiting post is provided at the front end of the second connecting block. A locking device is rotatably connected to the inner wall of the second connecting block, and the locking device is adapted to rotate to engage the limiting post. A slot is also provided at the front end of the second connecting block. The splicing mechanism also includes a pin, which passes through the inner wall of the first connecting block and the inner wall of the locking device in sequence and is inserted into the slot, thereby fixing the first connecting block and the second connecting block.

[0009] Preferably, a pipe insulation protection structure with a built-in aerogel core further includes a fixing mechanism for fixing the position of the insulation cotton relative to the protective shell, preventing the insulation cotton from undergoing unexpected axial movement after installation or during use. The fixing mechanism includes a fixing ring, which is fixed around the left and right ends of the insulation cotton.

[0010] Preferably, in the above-mentioned fixing mechanism, the outer wall of the fixing ring is provided with a locking block, which fits against the outer wall of the protective shell and serves as a connection interface between the fixing ring and the protective shell. The fixing mechanism also includes a bolt, which passes through the locking block and is threadedly connected to the protective shell. The fixing ring is securely installed on the protective shell by this threaded fastening method.

[0011] Preferably, as a further improvement to the fixing mechanism, the outer wall of the fixing ring is also provided with a positioning post, which engages with the top of the heat insulation cotton. This positioning post is designed to help lock the position of the fixing ring relative to the heat insulation cotton, ensuring that the fixing ring will not easily slip or shift when installed on the heat insulation cotton.

[0012] Preferably, in the splicing mechanism, there are two limiting posts, which are symmetrically arranged at the rear end of the first connecting block. Correspondingly, there are also two slots, which are formed at the front end of the second connecting block. The two limiting posts and the two slots cooperate with each other to provide a stable and reliable insertion guide.

[0013] Preferably, in the splicing mechanism, the locking mechanism is adapted to rotate on the inner wall of the connecting block two. The left end of the locking mechanism forms a hook-shaped structure. When the locking mechanism rotates, the left end can engage with the limiting post inserted into the slot, thereby achieving initial locking of the connecting block one.

[0014] Preferably, the lining is used to prevent the insulation cotton from directly contacting the pipe. The lining is preferably a flexible high-temperature resistant material that can both isolate the insulation cotton and adapt to the shape of the pipe, thus avoiding direct interaction between the insulation material and the high-temperature pipe.

[0015] Preferably, the cushioning cotton is used to reduce the transmission of external vibrations to the insulation cotton to prevent the insulation cotton from breaking. This cushioning cotton is preferably an elastic shock-absorbing material, which is wrapped between the insulation cotton and the protective shell to form an effective vibration buffer layer and protect the internal insulation cotton.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem in the prior art that the insulation cotton is prone to displacement due to vibration or gravity, resulting in partial exposure of the pipeline and the formation of insulation blind spots, by setting a fixing mechanism, which includes a fixing ring fixed to the end of the insulation cotton, and a clamp and bolt for connecting the fixing ring to the protective shell. The insulation cotton is firmly fixed to the protective shell, effectively preventing axial displacement and ensuring the integrity and reliability of pipeline insulation.

[0018] 2. This utility model, by setting up a splicing mechanism, includes a connecting block one and a connecting block two fixed to the ends of adjacent protective shells and capable of locking each other through a latch and a pin, solves the problem in the prior art that the length of the pipe protective shell is fixed and it is difficult to flexibly adjust the total length according to the actual working conditions. It facilitates the splicing of multiple protective shells and flexibly adjusts the total length of the overall protective structure, thereby improving the applicability and installation convenience of the device.

[0019] 3. This utility model solves the problem that the aerogel core, which is used as a heat insulation material in the prior art, is brittle and easily damaged by external vibration or impact by setting a buffer cotton between the heat insulation cotton and the protective shell. It effectively absorbs and buffers external vibration, protects the internal heat insulation cotton from damage, and thus extends the service life of the entire heat insulation structure.

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.

[0028] Example:

[0029] Please refer to Figures 1 to 5 This utility model provides a pipe thermal insulation protection structure with built-in aerogel core, which aims to solve the problems in the prior art where the thermal insulation material is prone to axial displacement, resulting in thermal insulation blind spots, and the thermal insulation material is easily damaged by vibration, and the length of the protective shell 2 is difficult to adjust.

[0030] like Figure 1 As shown, a pipe insulation protection structure with an embedded aerogel core includes an inner liner 5, insulation cotton 1, buffer cotton 6, and a protective shell 2. The inner liner 5 is wrapped around the outer wall of the pipe, the insulation cotton 1 is wrapped around the outer wall of the inner liner 5, the buffer cotton 6 is wrapped around the outer wall of the insulation cotton 1, and the protective shell 2 is wrapped around the outer wall of the buffer cotton 6. The inner liner 5 is used to prevent the insulation cotton 1 from directly contacting the pipe, and the buffer cotton 6 is used to reduce the transmission of external vibrations to the insulation cotton 1 to prevent the insulation cotton 1 from being damaged.

[0031] It also includes a splicing mechanism 3, which is used to connect adjacent protective shells 2. Please refer to [reference needed]. Figures 1 to 3The splicing mechanism 3 includes a first connecting block 301 and a second connecting block 302. The first connecting block 301 is fixedly connected to the end of the protective shell 2, and the second connecting block 302 is fixedly connected to the end of another adjacent protective shell 2. The rear end of the first connecting block 301 is provided with two limiting posts 304. The front end of the second connecting block 302 is provided with two slots 305. The limiting posts 304 and slots 305 are correspondingly engaged, and the slots 305 are used to accommodate the limiting posts 304. The inner... The wall is rotatably connected with a locking 303, which is adapted to rotate on the inner wall of the second connecting block 302. The left end of the locking 303 is used to engage the limiting post 304. The front end of the second connecting block 302 is provided with a slot 306. The splicing mechanism 3 also includes a pin 307, which passes through the inner wall of the first connecting block 301 and the inner wall of the locking 303 in sequence and is inserted into the slot 306 to fix the first connecting block 301 and the second connecting block 302. It also includes a fixing mechanism 4, which is used to fix the position of the heat insulation cotton 1 relative to the protective shell 2.

[0032] Please refer to Figure 1 , Figure 4 and Figure 5 The fixing mechanism 4 includes a fixing ring 401, a positioning post 402, a locking block 403, and a bolt 404. The fixing ring 401 is fixed around the left and right ends of the heat insulation cotton 1. The outer wall of the fixing ring 401 is provided with a positioning post 402, which is engaged with the top of the heat insulation cotton 1 to help lock the position of the fixing ring 401 relative to the heat insulation cotton 1 and prevent the fixing ring 401 from sliding relative to the heat insulation cotton 1.

[0033] The outer wall of the fixing ring 401 is also provided with a locking block 403. The locking block 403 fits against the outer wall of the protective shell 2. The bolt 404 passes through the locking block 403 and is threaded to the protective shell 2. Through the tightening action of the bolt 404, the locking block 403 and the fixing ring 401 are firmly fixed to the outer wall of the protective shell 2. This connection structure formed by the fixing ring 401, the positioning post 402, the locking block 403 and the bolt 404 finally anchors the heat insulation cotton 1 to the protective shell 2 via the fixing ring 401, ensuring that the heat insulation cotton 1 cannot be axially displaced, thereby effectively avoiding the generation of heat insulation blind spots.

[0034] In a preferred embodiment, the splicing mechanism 3 has two limiting posts 304, which are symmetrically arranged at the rear end of the first connecting block 301. Correspondingly, the second connecting block 302 also has two slots 305, with the two limiting posts 304 and the two slots 305 corresponding to each other.

[0035] In another preferred embodiment, the locking 303 is rotatably connected to the inner wall of the connecting block 302 via a rotating shaft. The left end of the locking 303 forms a hook-shaped structure, which is used to engage the two limiting posts 304 when rotating, thereby achieving initial locking.

[0036] As another preferred embodiment, the lining 5 is preferably a flexible high-temperature resistant material, which is wrapped around the outer wall of the pipe to physically isolate the insulation cotton 1 from the pipe and prevent the high-temperature pipe from directly affecting the insulation cotton 1 or causing chemical corrosion.

[0037] As another preferred embodiment, the cushioning cotton 6 is preferably an elastic shock-absorbing material, disposed between the heat insulation cotton 1 and the protective shell 2, to absorb and cushion external vibrations or impacts from the protective shell 2, so as to prevent the relatively fragile internal heat insulation cotton 1 from being damaged or broken.

[0038] Working principle:

[0039] During installation, the inner lining 5 is first wrapped around the outer wall of the pipe. The inner lining 5 is used to prevent the insulation cotton 1 from directly contacting the pipe. Then, the insulation cotton 1 is wrapped around the outer wall of the inner lining 5. Next, a layer of buffer cotton 6 is wrapped around the outer wall of the insulation cotton 1. The buffer cotton 6 is used to reduce the transmission of external vibration to the insulation cotton 1 during subsequent use, so as to prevent the insulation cotton 1 from being damaged.

[0040] Then, install the protective shell 2. When it is necessary to splice two protective shells 2, align and fit the connecting block 301 at the end of the protective shell 2 with the connecting block 302 at the end of the adjacent protective shell 2. At this time, the two limiting posts 304 at the rear end of the connecting block 301 are inserted into the two corresponding slots 305 at the front end of the connecting block 302. Then, rotate the locking 303 on the inner wall of the connecting block 302 so that the left end of the locking 303 engages with the two limiting posts 304. Finally, pass the pin 307 through the inner wall of the connecting block 301 and the inner wall of the locking 303 in sequence, and insert it into the slot 306 of the connecting block 302. The pin 307 firmly locks the connecting block 301 and the connecting block 302, completing the connection of the splicing mechanism 3 and realizing the flexible adjustment of the length of the protective shell 2.

[0041] After the protective shell 2 is installed in place, in order to fix the insulation cotton 1, the fixing ring 401 of the fixing mechanism 4 is fixed around the left and right ends of the insulation cotton 1. The positioning post 402 on the outer wall of the fixing ring 401 is engaged with the top of the insulation cotton 1 to help lock the fixing ring 401 and prevent it from sliding on the insulation cotton 1. Then, the locking block 403 on the outer wall of the fixing ring 401 is attached to the outer wall of the protective shell 2. The bolt 404 is passed through the locking block 403 and threaded to the protective shell 2. The fixing ring 401 is firmly fixed to the protective shell 2 by the bolt 404, thereby locking the end position of the insulation cotton 1, effectively preventing the insulation cotton 1 from axial displacement, and solving the problem of local pipe exposure forming insulation blind spots.
