Problems solved by technology
[0004] The above method has the following problems: 1) Due to the small operating space at the bottom of the liquid tank, the installation of the prefabricated panel and the insulating layer at the bottom of the liquid tank will be very troublesome, especially the installation of the prefabricated panel is inconvenient, time-consuming and laborious; 2) The above method must be carried out Multiple times of polyurea spraying, so the bottom of the tank after insulation is uneven and unsightly; 3) It is necessary to spray the insulation layer on the bottom of the tank first, and then further heat insulation, the process is cumbersome

The invention relates to a thermal insulation structure of a support point of a liquid tank and a manufacturing method thereof. It includes a prefabricated panel (5), a first glass mesh (6), a second glass mesh (7) and a wire mesh (8). The prefabricated panel (5) includes a first extending side (5.2.1) and a second The extension edge (5.2.2), the first extension edge (5.2.1) is fixed on the support (2), and two adjacent prefabricated panels (5) are installed side by side through the second extension edge (5.2.2), One side of the first glass mesh (6) is bonded to the support (2), and the other side is set on the inner surface of the polyurea board (5.1), the prefabricated board (5), the support (2) and the tank (1) The opening is formed to fill the foam layer (4), one side of the barbed wire (8) is arranged on the outer surface of the prefabricated board (5), and the other side supports the lower part of the foam layer (4). The invention is easy to install, has good insulation effect, and makes the bottom of the liquid tank beautiful.
Description
technical field [0001] The invention relates to a heat preservation structure of a support point of a liquid tank and a manufacturing method thereof, and is generally used for heat preservation of a deck tank of a ship. Background technique [0002] The LNG carrier is a special ship for transporting liquefied gas at a low temperature of minus 162 degrees Celsius. It is a "three-high" product with high technology, high difficulty and high added value, and a "sea super refrigerated vehicle". The liquid tank of an LNG ship is a special structure independent of the hull. For the storage and transportation of low-temperature liquefied gas, excellent insulation is indispensable, and the insulation of the support point between the liquid tank and the hull is particularly important. [0003] The existing insulation of the supporting point between the liquid tank and the hull adopts the following process: 1) spray the insulating layer on the bottom of the liquid tank first; 2) make m...
