Description

Technical Field

[0001] The utility model relates to the technical field of pipeline insulation, in particular to a thermal pipeline insulation device. Background Art

[0002] Thermal pipelines are pipelines that transport thermal energy media such as steam or superheated water. Existing thermal pipelines are generally buried directly underground. Thermal pipelines lose a lot of heat in the process of transporting thermal energy media such as hot water. Therefore, it is necessary to set up insulation structures in thermal pipelines to reduce heat loss.

[0003] Existing thermal pipe insulation methods mostly involve wrapping insulation materials around the outside of thermal pipes to achieve the insulation effect. However, since mineral wool and polyurethane foam materials are highly hygroscopic, the insulation layer is easily affected by moisture and corroded when the ambient humidity is high, which reduces the insulation performance of the material and increases the heat dissipation loss of the pipe. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the insulation layer of the existing thermal pipeline is easily damaged by moisture corrosion, which reduces the insulation performance of the material.

[0005] In order to solve the above problems, the technical solution of the utility model is: a thermal pipe insulation device, comprising a thermal pipe and an insulation component installed on the outside of the thermal pipe, the insulation component comprising an upper shell and a lower shell with the same internal structure, an inner liner is provided inside the upper shell, an insulation board is provided between the inner liner and the upper shell, and polyurethane insulation material is filled between the inner liner and the insulation board, mortar is filled between the insulation board and the upper shell, two feed pipes 1 for filling mortar are symmetrically fixed to the upper shell, two feed pipes 2 for filling polyurethane insulation material are symmetrically fixed to the insulation board, and positioning strips 1 and 2 are respectively fixed to both ends of the upper shell and the lower shell.

[0006] Furthermore, upper fixing bars are fixedly connected to both sides of the upper shell, and lower fixing bars are fixedly connected to both sides of the lower shell. The upper fixing bars and the lower fixing bars are connected and fixed by a plurality of bolts and nuts.

[0007] Furthermore, both ends of the lining and the heat insulation board are fixed to the inner walls at both ends of the upper shell.

[0008] Furthermore, the inner lining is a flexible thin plate, and the inner lining fits the outer wall of the thermal pipe.

[0009] Furthermore, a plurality of connection blocks are fixedly connected between the heat insulation plate and the inner wall of the upper shell.

[0010] Furthermore, the center lines of the feed pipe 1 and the feed pipe 2 coincide with each other, and the inner diameter of the feed pipe 1 is larger than the outer diameter of the feed pipe 2, and top covers are installed on the tops of the feed pipe 1 and the feed pipe 2.

[0011] Furthermore, the first positioning bar and the second positioning bar are both semicircular ring structures, and the inner diameter of the first positioning bar is the same as the outer diameter of the second positioning bar.

[0012] The advantages of the utility model compared with the existing technology are: the utility model can enhance the thermal insulation effect of the thermal pipeline through the combination of polyurethane thermal insulation material and thermal insulation board, and can improve the protection effect of the thermal pipeline through the mortar layer, and can play a further thermal insulation role at the same time, and effectively reduce the influence of the external environment on the polyurethane thermal insulation material through the upper shell, lower shell, mortar and thermal insulation board, thereby ensuring the thermal insulation effect and service life of the polyurethane thermal insulation material.
