Steep the device and method of heat insulation layer.
Background technique
With the popularization that liquefaction gas uses, low-temperature liquid gas holding vessel usage amount is increasing.Due to this storage
It deposits tank needs to be under pressure, therefore is generally designed to rotary body, what wherein stress more rationally manufactured relatively convenient is such as
Cylindrical body and spherical shape.To make storage safety, needs to make the liquefied gas in storage tank to be in a very low temperature, so just require
This kind of storage tank has good insulation, to prevent extraneous temperature from transmitting into tank.And existing heat-insulating material most has economical and practical valence
The relatively very low material of value, thermal coefficient is exactly microfoam quasi polymer, such as polystyrene foam, polyurethane foam.
It is used today to have two major classes method in similar large-sized object outer cladding frothing heat-insulating layer, after mould-forming assembly and
Live hand spray.Former approach is since mold relationship is suitable only for producing by batch on a large scale, later approach final product quality
It not can guarantee and inefficiency.In addition, means of needing reinforcement itself is allowed to since foamed material belongs to low-intensity material mostly
Have good connection with tank body, inevitably, above two method is required to other structural strengthening, this again to manufacture and self weight
Mitigation increases unfavorable factor.The purpose of the present invention is to solve the above-mentioned problems and propose.
Summary of the invention
The purpose of the present invention is to provide the device and method in the large-scale fiber forced foamed heat insulation layer of rotary body outer cladding,
