Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for chemical equipment, and in particular to a safety protection cover for chemical pipelines. Background Technology

[0002] In the chemical production process, chemical pipelines play a vital role in transporting corrosive, flammable, explosive, or high-temperature and high-pressure media, and their safety is of paramount importance.

[0003] However, existing protective measures for chemical pipelines have many shortcomings: on the one hand, traditional protective structures are mostly made of a single material, making it difficult to simultaneously meet multiple requirements such as impact resistance, fire prevention, heat insulation, and corrosion resistance. Pipelines are prone to safety accidents due to external impacts, high temperatures, or media leaks. On the other hand, traditional protective devices are inconvenient to install and dismantle, requiring significant manpower and resources for pipeline maintenance and repair, and are difficult to replace or upgrade quickly. Therefore, there is an urgent need to develop a robust, multifunctional, and easily installable safety cover for chemical pipelines to improve the safety and reliability of chemical pipeline operations. Utility Model Content

[0004] The main objective of this invention is to provide a safety cover for chemical pipelines, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A safety cover for a chemical pipeline includes a chemical pipeline body, on the outer surface of which two protective devices are fitted, and the upper and lower ends of the two protective devices are fixedly connected to an installation device.

[0007] The protective device includes a rectangular mounting frame, within which an alloy steel plate, a thermal insulation board, and a fire-retardant rubber are sequentially arranged. The left end of each of the alloy steel plate, the thermal insulation board, and the fire-retardant rubber has a through hole with the same diameter as the chemical pipeline body.

[0008] Preferably, the alloy steel plate, thermal insulation board, and fire-retardant rubber are all fixedly connected to the upper and lower inner walls of the rectangular mounting frame, and the through holes of the three are coaxially arranged to form a circular channel adapted to the chemical pipeline body.

[0009] The above solution, through the fixation of three layers of materials and frame and the design of coaxial through holes, ensures that the protective layer fits tightly to the pipeline, forming a complete sealing structure, improving the impact resistance, fire resistance, and heat insulation performance, and ensuring the safe operation of the pipeline.

[0010] Preferably, the alloy steel plate is fixed to the inner wall of the rectangular mounting frame by welding, and the thermal insulation board and the alloy steel plate, as well as the fireproof and flame-retardant rubber and the thermal insulation board, are bonded together by high-temperature resistant adhesive.

[0011] The above solution, which combines welding with high-temperature resistant adhesives, enhances the interlayer bonding strength and stability, adapts to high-temperature environments, prevents interlayer peeling, and extends the service life of the protective device.

[0012] Preferably, the installation device includes connecting plates, and two connecting plates are provided. Each of the two connecting plates has five through-holes on its left end. Ten positioning holes are connected to each other in pairs, and threaded grooves are provided on the left and right sides of the outer surfaces of the five insertion rods. Ten threaded grooves are threaded with fastening nuts.

[0013] The above solution, with its detachable connection structure between the plug and the nut, enables rapid assembly and disassembly of the protective device without the need for specialized tools, thus shortening installation time, reducing labor costs, and facilitating maintenance and upgrades.

[0014] Preferably, the lower ends of the two connecting plates are fixedly connected to the upper ends of the two rectangular mounting frames, and the two connecting plates and the two rectangular mounting frames are integrally fixedly connected.

[0015] The above solution improves structural rigidity through integrated fixing design, ensures uniform stress distribution, avoids loosening and deformation at connections, enhances the overall stability of the protective device, and is suitable for pipeline protection in vibration environments.

[0016] Preferably, the outer diameter of the insertion rod is clearance-fitted with the inner diameter of the positioning hole, and the length of both ends of the insertion rod extending out of the positioning hole is not less than 20mm.

[0017] The above solution, with its precise clearance fit and extension length design, ensures smooth installation of the insertion rod while providing sufficient threaded connection length to guarantee reliable fastening force and prevent loosening and detachment.

[0018] Preferably, the right ends of the five fastening nuts on the left side are tightly fitted with the left end of the left connecting plate, and the left ends of the five fastening nuts on the right side are tightly fitted with the right end of the right connecting plate.

[0019] The above solution, with its tight fit between the nut and the connecting plate, eliminates gaps, enhances preload, effectively resists vibration and impact, prevents thread loosening, and ensures long-term safety.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In this utility model, the protective device adopts a structure in which an alloy steel plate, a heat insulation board and a fire-retardant rubber are arranged in sequence within a rectangular mounting frame. The alloy steel plate can resist external impact, the heat insulation board can isolate heat, and the fire-retardant rubber can prevent the spread of fire. The multiple materials work together to meet multiple requirements such as impact resistance, fire prevention, heat insulation and corrosion resistance, effectively reducing the risk of safety accidents caused by external collisions, high temperatures or media leakage.

[0022] 2. In this utility model, the installation device achieves quick installation and disassembly of the protective device through the cooperation of the connecting plate, positioning hole, insertion rod, threaded groove and fastening nut. During pipeline inspection and maintenance, the protective device can be disassembled simply by loosening the fastening nut and pulling out the insertion rod, which greatly reduces the consumption of manpower and material resources, and facilitates the quick replacement and upgrading of the protective device.

[0031] Please see Figure 1-4 This utility model provides a technical solution:

[0032] A safety cover for a chemical pipeline includes a chemical pipeline body 1, and two protective devices 2 are fitted on the outer surface of the chemical pipeline body 1. The upper and lower ends of the two protective devices 2 are fixedly connected to an installation device 3.

[0033] In this embodiment, the protective device 2 includes a rectangular mounting frame 21. An alloy steel plate 22, a thermal insulation board 23, and a fire-retardant rubber 24 are sequentially arranged inside the rectangular mounting frame 21. A through hole 25, with the same diameter as the chemical pipeline body 1, is opened at the middle of the left end of each of the alloy steel plate 22, thermal insulation board 23, and fire-retardant rubber 24. The alloy steel plate 22, thermal insulation board 23, and fire-retardant rubber 24 are all fixedly connected to the upper and lower inner walls of the rectangular mounting frame 21, and the through holes 25 of the three are coaxially arranged to form a circular channel adapted to the chemical pipeline body 1. The alloy steel plate 22 is fixed to the inner wall of the rectangular mounting frame 21 by welding. The thermal insulation board 23 is bonded to the alloy steel plate 22, and the fire-retardant rubber 24 is bonded to the thermal insulation board 23 by high-temperature resistant adhesive.

[0034] Through the above scheme: the protective device 2 is supported by a rectangular mounting frame 21, and an alloy steel plate 22, a thermal insulation board 23, and a fire-retardant rubber 24 are sequentially installed inside. The alloy steel plate 22 is fixed to the frame by welding, serving as the outer layer to resist external impact; the thermal insulation board 23 is connected to the alloy steel plate 22 by a high-temperature resistant adhesive to isolate heat transfer; the fire-retardant rubber 24 is also fixed with adhesive to prevent the spread of fire. The through holes 25 of the three are coaxial, forming a channel that fits the chemical pipeline body 1. By fixing it to the upper and lower inner walls of the frame, it is ensured that the protective layer tightly wraps the pipeline. The various materials each perform their respective functions, working together to provide the pipeline with impact resistance, heat insulation, fire protection, and other protections.

[0035] In this embodiment, the mounting device 3 includes two connecting plates 31. Each connecting plate 31 has five through-holes 32 on its left end. Ten positioning holes 32 are connected to each other in pairs, and insert rods 33 are inserted into each pair. The left and right sides of the outer surfaces of the five insert rods 33 are provided with threaded grooves 34, and ten threaded grooves 34 are threaded with fastening nuts 35. The lower ends of the two connecting plates 31 are fixedly connected to the upper ends of the two rectangular mounting frames 21, and the two connecting plates 31 and the two rectangular mounting frames 21 are integrally fixedly connected. The outer diameter of the insert rods 33 is clearance-fitted with the inner diameter of the positioning holes 32, and the length of the insert rods 33 extending out of the positioning holes 32 is not less than 20mm. The right ends of the five fastening nuts 35 on the left side are tightly fitted with the left ends of the left connecting plate 31, and the left ends of the five fastening nuts 35 on the right side are tightly fitted with the right ends of the right connecting plate 31.

[0036] The above solution involves two connecting plates 31 being integrally fixed with the rectangular mounting frame 21. The positioning holes 32 on the plates provide installation positions for the insert rods 33. During installation, the insert rods 33 are passed through the corresponding positioning holes 32. The gap between the outer diameter and the inner diameter of the positioning holes 32 ensures that the insert rods 33 can be inserted smoothly. The threaded grooves 34 at both ends of the insert rods 33 cooperate with the fastening nuts 35. Tightening the nuts makes the connecting plates 31 on both sides fit tightly, generating a preload force to firmly connect the two protective devices 2. During disassembly, the insert rods 33 can be pulled out by loosening the nuts 35, achieving quick assembly and disassembly.

[0037] It should be noted that this utility model is a safety protective cover for chemical pipelines. In the process of use, firstly, the rectangular mounting frames 21 of the two protective devices 2 are respectively fitted onto the designated positions of the chemical pipeline body 1. The alloy steel plate 22, heat insulation board 23 and fire-retardant rubber 24 inside each protective device 2 have been fixed by welding and high-temperature adhesive. The through hole 25 is coaxially adapted to the pipeline. The two connecting plates 31 are integrally fixed to the upper end of the rectangular mounting frame 21 of the protective device 2. The insertion rod 33 is passed through the positioning hole 32, so that the two ends of the insertion rod 33 extend out of the positioning hole 32 by no less than 20mm. The fastening nut 35 is connected and tightened to the threaded groove 34. The two protective devices 2 are then firmly installed on the chemical pipeline body 1. After installation, the alloy steel plate 22 resists external impact, the heat insulation board 23 isolates heat, and the fire-retardant rubber 24 prevents fire, jointly ensuring the safe operation of the chemical pipeline.
