[0002] Resin usually refers to an organic polymer that softens or melts when heated, tends to flow under external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. In a broad sense, any polymer compound that can be used as a raw material for plastic products is called a resin. At present, in the production process of resin, trimethylamine can be recovered from its mother liquor and COD (chemical oxygen demand) can be reduced. In the process of recovering and reusing trimethylamine from the mother liquor, continuous distillation is required. The distillation process is carried out in a distillation tower. The distillation tower is provided with a number of conveying pipelines (including input pipelines and output pipelines). In order to reduce the heat loss in the conveying pipeline, some conveying pipelines are wrapped with spiral insulation tapes or insulation sleeves, and it is necessary to realize a structure in which the insulation sleeve or the insulation tape is fixed on the conveying pipeline. The installation of the insulation sleeve and the insulation tape is relatively troublesome. Moreover, there is no protective structure on the outside of the insulation tape and the insulation sleeve. The outer surface of the insulation tape and the insulation sleeve is easily scratched or damaged, so it is necessary to design a structure for convenient installation and protection of the pipeline outer insulation. Utility model content:

[0003] The purpose of the utility model is to address the deficiencies of the prior art and to provide an insulation structure on the external pipeline of a resin mother liquor continuous distillation tower.

[0005] At least two clamping rings are provided, and the clamping rings are evenly distributed on the sponge thermal insulation pipe sleeve in a linear vertical direction. The upper and lower ends of the sponge thermal insulation pipe sleeve are respectively provided with clamping rings.

[0006] The upper and lower ends of the outer protective thin plate are respectively bent to form arc-shaped ribs, and the ribs are distributed on the upper and lower sides of the sponge insulation pipe sleeve.

[0007] An avoidance slot hole opposite to the rivet is formed on the outer wall of the outer protective sheet close to the folded edge, and the aperture of the avoidance slot hole is larger than the aperture of the plug hole on the support ear.

[0008] The cut grooves on the sponge thermal insulation pipe sleeve and the notches on the clamping ring are distributed on both sides of the conveying pipeline.

[0009] The cross section of the clamp ring is circular; the diameter of the inner ring of the clamp ring is smaller than the diameter of the outer wall of the sponge insulation pipe sleeve, and the diameter of the outer ring of the clamp ring is not larger than the diameter of the inner wall of the outer protective thin plate.
