Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipeline thermal insulation, in particular to a thermal insulation device suitable for the surface of a high-temperature pipeline. Background Art
[0002] Since the viscosity of oil is high at room temperature, it is actively heated during the extraction, transportation and processing of oil and natural gas to reduce its viscosity and enhance its fluidity. Even if the pipeline is equipped with an insulation layer, during long-term continuous use, the heat will gradually transfer to the surface of the high-temperature pipeline, and the temperature may be very high. In order to protect the pipeline, it is necessary to ensure its contact with the air to dissipate the heat, and the pipeline cannot be directly closed. However, even if the warning signs are set, workers may touch it during operation, and the high temperature may cause skin burns and injury. Utility Model Content
[0003] The purpose of the utility model is to provide a reasonably designed heat insulation device suitable for the surface of a high-temperature pipeline in view of the defects and shortcomings of the prior art, which can solve the above-mentioned defects.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it comprises a steel wire mesh rolled into a ring, a plurality of springs are arranged on the inner side of the steel wire mesh, a plurality of axial connecting rings are arranged on the longitudinal side edges of the steel wire mesh, and straight connecting iron wires are movably inserted in the plurality of axial connecting rings.
[0005] Preferably, a plurality of circumferential connecting rings are evenly arranged at the top and bottom of the wire mesh, and the installation positions of the circumferential connecting rings at the top and bottom of the wire mesh match.
[0006] Preferably, the plurality of springs are arranged in groups, each group comprising a plurality of springs of the same height and uniformly arranged on the inner side of the wire mesh along the circumference, and the plurality of springs are uniformly arranged on the inner side of the wire mesh longitudinally.
[0007] Preferably, the number of springs in each group is not less than three.
[0008] Preferably, both ends of the connecting iron wire are bent outwards.
[0009] After adopting the above structure, the beneficial effects of the utility model are:
[0010] The device uses springs to prop up the steel mesh so that the pipe wall and the steel mesh are not in direct contact, and uses the air between the two for heat insulation, thereby preventing maintenance operators from directly contacting the pipe wall and thus preventing burns.
[0011] The device is modular in design and can be applied to pipes of different diameters and lengths. It is easy to obtain materials and has low cost. BRIEF DESCRIPTION OF THE DRAWINGS
