A kind of marine low-temperature storage tank covered with thermal insulation material and construction method thereof

Abstract

The invention relates to a low-temperature storage tank coated heat insulation material used for a boat, and relates to the field of production of low-temperature pressure vessels used for the boat. The low-temperature storage tank coated heat insulation material used for the boat comprises a drum body and end sockets. The two ends of the drum body are both provided with a circle of steel nails and are coated with multiple layers of bedding. Each layer comprises end bedding and middle bedding. The front edge of the first end bedding penetrates through the steel nails at the front end of the drum body, and the front edge of the middle bedding presses the rear edge of the previous end bedding. The front edge of the second end bedding presses the rear edge of the middle bedding, and the rear edge of the second end bedding penetrates through the steel nails at the rear end of the drum body. The center of each steel nail is provided with steel nails and is coated with multiple layers of bedding. Each layer of bedding comprises two end bedding, and the two end bedding are in a sector shape, wherein the inner arc sides are fixed to the steel nails at the centers of the bedding, and the outer arc sides are fixed to the steel nails which are close to one end of the drum body. Two straight sides of one end socket bedding are coated on the two straight sides of another end socket bedding. The splicing positions of different layers of bedding are staggered, and the bedding at the outermost layer is coated with a layer of glass wool cloth. The low-temperature storage tank coated heat insulation material used for the boat has the advantages that the construction efficiency is improved, the use ratio of raw materials is improved, and the low-temperature usability of a finished product is improved.

Description

technical field [0001] The invention relates to the field of manufacturing low-temperature pressure vessels for ships, in particular to a low-temperature storage tank for ships coated with heat insulating materials and a construction method thereof. Background technique [0002] In the design and manufacture of marine low-temperature storage tanks, horizontal double-layer pressure vessels are generally used. The inner and outer vessels are made of austenitic stainless steel. The outer surface of the inner vessel is made of aluminum foil or double-sided aluminized polyester film as a reflective screen. Or the thickness of the double-sided aluminized polyester film is about 0.005-0.025mm; the glass fiber paper or glass fiber cloth is used as a spacer between the two reflective screens, and the thickness of the glass fiber paper is about 0.015-0.1mm. [0003] At present, the thermal insulation materials purchased from suppliers are generally in bulk form, that is, a layer of al...

AI Technical Summary

Problems solved by technology

In order to ensure the construction quality of thermal insulation materials, special care must be taken in the construction process, and the construction efficiency is not high

Even so, some insulation materials will still be damaged during the construction process, which affects the utilization rate of raw materials

If the damaged thermal insulation material is wrapped on the inner container, or the quality of the wrapping is not good, the low-temperature performance of the subsequent finished product will be reduced
