Abstract
The invention discloses a marine natural gas storage tank provided with a buffer structure, and belongs to the technical field of manufacturing of storage tanks. As buffer plates are arranged, and are funnel-shaped, the impact of liquid when being shaken in the storage tank is counteracted by inclined surfaces of the buffer plates. In addition, as the bottoms of the multiple buffer plates positioned at the same side of a radial surface are opposite to the bottoms of the buffer plates at the other side, when the liquid is shaken from one end of the storage tank to the other end, is buffered through the funnel-shaped inclined surfaces of the buffer plates, and is collected in through holes in the bottom for flowing. When the volume of the liquid in the storage tank is lower, the liquid flows through an opening in the bottom of the storage tank.

For addressing the above problem, the invention provides a kind of simple in structure, the safe and reliable natural gas storage tank peculiar to vessel that is provided with buffer structure.
The present invention is that the technological scheme that its problem of solution adopts is:
A kind of natural gas storage tank peculiar to vessel that is provided with buffer structure, comprise inner casing and shell, the inwall of described inner casing is provided with several buffer structures, described buffer structure comprises a cushion plate, described cushion plate is funnel-like, its bottom is provided with through hole, in the periphery of cushion plate, is provided with outer shroud, and the arranged outside of described outer shroud has flank to be connected with the inwall of inner casing; Between the inner side of outer shroud and the periphery of cushion plate, be provided with the opening that liquid passes through, this opening is positioned at the bottom of cushion plate; Described several buffer structures are symmetrical along the radial cross section of storage tank center, wherein, be positioned at above-mentioned sagittal plane the same side cushion plate bottom be oppositely arranged with the bottom that is positioned at the cushion plate of opposite side; In addition, be provided with pillar and be connected between inner casing and shell, above-mentioned pillar and buffer structure are positioned at same radial cross section.
Preferably, the bottom of described inner casing is provided with projection between two adjacent openings, and the cross section of described projection is triangle, and this leg-of-mutton bottom surface is cemented in the bottom of inner casing, and two other side is respectively towards two adjacent openings.
Further, described projection is the direction setting in cross section radially, or projection favours radial cross section setting.
Preferably, the cross section of described funnelform cushion plate is triangle, and the bottom angle in its cross section is between 90 degree～180 degree.Further, described angle is 150 degree.
Preferably, between described inner casing and shell, on same radial cross section, be symmetrically arranged with a plurality of pillars.
Preferably, described pillar adopts epoxy glass stringing.
Preferably, the bottom of described shell, be positioned on same radial cross section and be provided with for supporting the supporting base of storage tank with pillar.
The invention has the beneficial effects as follows: owing to being provided with cushion plate, cushion plate is funnel shape, impact when liquid rocks in storage tank will be cushioned the plane of inclination of plate and offset.In addition, the present invention by several are positioned at above-mentioned sagittal plane the same side cushion plate bottom be oppositely arranged with the bottom that is positioned at the cushion plate of opposite side, while making liquid shake to the other end from one end of storage tank, funnel shape inclined-plane by cushion plate cushions, meanwhile, liquid be collected into bottom through hole flow through.When liquid capacity in storage tank is less, liquid just circulates by the opening of tank bottom.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is internal structure side view of the present invention;
Fig. 2 is internal structure plan view of the present invention.
In figure: 1, inner casing; 2, shell; 3, cushion plate; 4, through hole; 5, outer shroud; 6, flank; 7, opening; 8, projection; 9, pillar; 10, supporting base.
Embodiment
A kind of natural gas storage tank peculiar to vessel that is provided with buffer structure as shown in accompanying drawing 1,2, comprise inner casing 1 and shell 2, the inwall of described inner casing 1 is provided with several buffer structures, described buffer structure comprises a cushion plate 3, described cushion plate 3 is funnel-like, its bottom is provided with through hole 4, and the cross section of described funnelform cushion plate 3 is triangle, and the bottom angle in its cross section is between 90 degree～180 degree.Through the test effect of different amount, described angle is that 150 cushioning effects while spending are best.In the periphery of cushion plate 3, be provided with outer shroud 5, the arranged outside of described outer shroud 5 has flank 6 to be connected with the inwall of inner casing 1; Between the periphery of the inner side of outer shroud 5 and cushion plate 3, be provided with the opening 7 that liquid passes through, this opening 7 is positioned at the bottom of cushion plate 3; Described several buffer structures are symmetrical along the radial cross section of storage tank center, wherein, be positioned at above-mentioned sagittal plane the same side cushion plate 3 bottom be oppositely arranged with the bottom that is positioned at the cushion plate 3 of opposite side.
Owing to being provided with cushion plate 3, cushion plate 3 is funnel shape, and impact when liquid rocks in storage tank will be cushioned the plane of inclination of plate 3 and offset.In addition, the present invention by several are positioned at above-mentioned sagittal plane the same side cushion plate 3 bottom be oppositely arranged with the bottom that is positioned at the cushion plate 3 of opposite side, while making liquid shake to the other end from one end of storage tank, funnel shape inclined-plane by cushion plate 3 cushions, meanwhile, liquid be collected into bottom through hole 4 flow through.When liquid capacity in storage tank is less, liquid just circulates by the opening 7 of tank bottom.
