Abstract
A bearing structure equipped in a liquified natural gas tank is characterized by a simple structure, an easy installation, a little of heat conduction, a high reliability and an adaptability for a plurality of thermal insulation modes. An upper bearing pipe is welded with a lower seal head equipped at an internal vessel and with an upper flange; a lower bearing pipe is welded with the seal heat equipped at an external vessel and with a lower flange; a thermal cushion is sandwiched between the upper flange and the lower flange to constitute an axial bearing. Three axial bearing are distributed around the circumference of the internal vessel. A fixation fitting is welded with a positioning ring in which is equipped a bearing bar used for holding down the fixation fitting. The bearing bar is also welded with the external vessel to constitute a radial bearing which is installed at the height of the internal vessel with a number from 3 to 6 pairs.
Description
Technical field
The utility model relates to splendid attire or stores the accessory structure of container of the container, particularly LNG Liquefied natural gas of liquid gas.
Background technique
Under normal pressure, the temperature of LNG Liquefied natural gas is-162 ℃, therefore requires the LNG Liquefied natural gas basin to have good heat-insulating property.Inner container is connected with outer container by inner supporting structure, and the mezzanine space filling heat insulator between interior outer container also vacuumizes.Traditional suspender belt and chain type supporting structure complexity, high material consumption, yielding are not suitable for the requirement to high vacuum multiple layer heat insulation.
Summary of the invention
The purpose of this utility model is to make LNG Liquefied natural gas basin inner supporting structure simple, is easy to install, and it is few to conduct heat, and good reliability also can adapt to multiple adiabatic method.
The utility model is a kind of LNG Liquefied natural gas basin inner supporting structure, be positioned between outer container (1) and the inner container (3), upper support pipe (4-1) welds with the lower seal head welding of inner container (3) and with upper flange (4-2), lower support pipe (4-5) welds with the lower seal head welding of outer container (1) and with lower flange (4-4), thermal insulating pad (4-3) is placed between upper flange (4-2) and the lower flange (4-4), upper flange (4-2), connect with bolt and nut between thermal insulating pad (4-3) and the lower flange (4-4), constitute an axially mounting (4), 3 axially mountings distribute along inner container (3) circumferencial direction; Fixed block (2-1) and positioning ring (2-2) welding, support strip (2-3) is placed in the positioning ring (2-2), fixed block (2-1) is compressed and weld, constitute a radial support (2), along the secondary radial support (2) of 3-6 is installed on inner container (1) height with outer container (1).Respectively have 2 pores (4-6), (4-6 ') on the lower support pipe (4-5).3 axially mountings evenly distribute along inner container (3) circumferencial direction.
The beneficial effects of the utility model are: the interior simplified no supporting structure of, be convenient to multilayer binding; Simple in structure, the installation of outer container in being convenient to; The axially mounting good rigidly, internally the damage of pipeline is little, the generation of minimizing accident; In the using process, radial support does not contact inner container, and it is few to conduct heat, and the evaporation loss of LNG Liquefied natural gas is little.
Description of drawings
Fig. 1 is a main sectional view of the present utility model, and Fig. 2 is the structural drawing of radial support, and Fig. 3 is the structural drawing of axially mounting.
Concrete implementation
As shown in Figure 1, the LNG Liquefied natural gas basin comprises outer container (1) and inner container (3), and outer container (1) is installed on the support (5), and inner supporting structure is positioned between outer container (1) and the inner container (3).3 countershafts distribute to the circumferencial direction of supporting (4) along inner container (3), the axial force when bearing the delivery transportation and the circumferential rotation of limiting content device (3), the total weight of inner container (3) and liquid when bearing use simultaneously.Along the secondary radial support (2) of 3-6, the vertical when bearing the delivery transportation are installed on the height of inner container (3); Inoperative during use.
As shown in Figure 2, fixed block (2-1) and positioning ring (2-2) welding, support strip (2-3) is placed in the positioning ring (2-2), fixed block (2-1) is compressed and weld with outer container (1), constitute a radial support (2), along the secondary radial support of 3-6 is installed on inner container (1) height.
As shown in Figure 3, upper support pipe (4-1) welds with the lower seal head welding of inner container (3) and with upper flange (4-2), lower support pipe (4-5) welds with the lower seal head welding of outer container (1) and with lower flange (4-4), thermal insulating pad (4-3) is placed between upper flange (4-2) and the lower flange (4-4), connect with bolt and nut between upper flange (4-2), thermal insulating pad (4-3) and the lower flange (4-4), constitute an axially mounting, 3 axially mountings distribute along inner container (3) circumferencial direction; Respectively have 2 pores (4-6), (4-6 ') on the lower support pipe (4-5).3 axially mountings are along being 120 ° even distribution on inner container (3) circumferencial direction.
Basin of the present utility model when manufacturing firm delivers, should take the to drop to the ground mode of transportation.The power vertically downward that inner container in the transportation (3) produces is born by radial support (2), and the power of fore-and-aft direction and circumferential rotation are born by axially mounting (4) or located.With the vertical placement of basin, axially mounting (4) bears the total weight of inner container (3) and LNG Liquefied natural gas during actual the use, and radial support (2) is no longer stressed.
Claims (2)
1, LNG Liquefied natural gas basin inner supporting structure, be positioned between outer container (1) and the inner container (3), it is characterized in that upper support pipe (4-1) welds with the lower seal head welding of inner container (3) and with upper flange (4-2), lower support pipe (4-5) welds with the lower seal head welding of outer container (1) and with lower flange (4-4), thermal insulating pad (4-3) is placed between upper flange (4-2) and the lower flange (4-4), upper flange (4-2), connect with bolt and nut between thermal insulating pad (4-3) and the lower flange (4-4), constitute an axially mounting (4), 3 axially mountings (4) distribute along inner container (3) circumferencial direction; Fixed block (2-1) and positioning ring (2-2) welding, support strip (2-3) is placed in the positioning ring (2-2), fixed block (2-1) is compressed and weld, constitute a radial support (2), along the secondary radial support (2) of 3-6 is installed on inner container (1) height with outer container (1).
2, LNG Liquefied natural gas basin inner supporting structure according to claim 1 is characterized in that respectively having on the lower support pipe (4-5) 2 pores (4-6), (4-6 '), and 3 axially mountings evenly distribute along inner container (3) circumferencial direction.
