Description
Technical field
The utility model is related to liquefied gas carrier field, more particularly to a kind of Type B independence rhombus cargo tank polycrystalline substance.
Background technology
Traditional IMO (ship code) Type B independence rhombus cargo tank bottom is typically all level design.In actual operation
In, due to the influence of the trim and heel of ship, liquid goods is often remained within the bottom plate of cargo tank during unloading, it is impossible to all imported
Into collection liquid trap, this directly influences the operating efficiency of deep well pump, so as to extend the unloading time at harbour.Since ship is vertical
Incline and heel is all unavoidable, how that overcomes the adverse effect thus brought, and improves the rate of discharging at harbour, is ability
Field technique personnel's technical issues that need to address.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of Type B independence rhombus of the rate of discharging at raising harbour
Cargo tank polycrystalline substance, to overcome the defect in prior art.
In order to solve the above-mentioned technical problem, the utility model is adopted the following technical scheme that：A kind of Type B independence rhombus cargo tank
Polycrystalline substance, the bottom surface of the cargo tank is provided with collection liquid trap, and the bottom surface of cargo tank includes at least four pieces bottom plates, all bottom plate splicings
Allow bottom surface to form a funnel-shaped structure from top to bottom, the collection liquid trap is provided with the lowest part of funnel-shaped structure.
Preferably, the bottom surface of cargo tank includes noseplate, rear bottom plate, left bottom plate and right bottom plate, the noseplate, rear bottom
Plate, left bottom plate and right bottom plate are tilted from cargo tank bottom edge to collection liquid trap side.
Further, the angle of inclination of the noseplate relative level is α 1, and α 1 scope is 0 ° of 1≤1 ° of ＜ α.
Further, the angle of inclination of the rear bottom plate relative level is α 2, and α 2 scope is 0 ° of 2≤1.5 ° of ＜ α.
Further, the angle of inclination of the left bottom plate relative level is β 1, and β 1 scope is 0 ° of 1≤4 ° of ＜ β.
Further, the angle of inclination of the right bottom plate relative level is β 2, and β 2 scope is 0 ° of 2≤4 ° of ＜ β.
Preferably, the collection liquid trap is close to the stern position of cargo tank.
As described above, the utility model Type B independence rhombus cargo tank polycrystalline substance, has the advantages that：
The utility model Type B independence rhombus cargo tank bottom design is funnel-shaped structure, and collection liquid trap is located at funnel-shaped structure
Lowest point, i.e. bottom plate is obliquely installed, even if to ensure that ship there occurs in default range of tilt angles vertical for bottom plate
Incline and heel, can be smoothly imported into collection liquid trap by self gravitation effect with liquid goods, and be unlikely to remain on bottom plate, improve
The operating efficiency of deep well pump, shortens the time in port discharge.Likewise it is preferred that angle can also avoid excessive loss
Volume of compartment, adds the practicality and aesthetic property of the design.

Embodiment
Structure, ratio, size depicted in Figure of description etc., only to coordinate the content disclosed in specification, with
Understand for those skilled in the art with reading, be not limited to the enforceable qualifications of the utility model, therefore do not have skill
Essential meaning in art, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influenceing the utility model institute
Under effect of energy generation and the purpose that can reach, the model that can cover in the technology contents disclosed in the utility model all should be fallen
In enclosing.Meanwhile, cited such as " on ", " under ", "front", "rear", " centre " term, are merely convenient to describe in this specification
Understand, and be not used to limit the enforceable scope of the utility model, its relativeness is altered or modified, without substantive change
Under technology contents, when being also considered as the enforceable category of the utility model.
The utility model is a kind of Type B independence rhombus cargo tank polycrystalline substance, as Figure 1-Figure 4, the cargo tank 1
Bottom surface is provided with the collecting tank 102 corresponding with collection liquid trap 2 position at the interior bottom 101 of hull 10, passes through liquid collecting provided with collection liquid trap 2
The liquid goods that groove will leak out is focused on.The bottom surface of cargo tank 1 of the present utility model includes at least four pieces bottom plates, and all bottom plate splicings allow
Bottom surface forms a funnel-shaped structure from top to bottom, the collection liquid trap 2 is provided with the lowest part of funnel-shaped structure, because cargo tank
Bottom surface be in funnel-shaped structure, therefore cargo tank 1 in liquid goods can be pooled to liquid collecting along inclined-plane by the Action of Gravity Field of itself
In trap 2, and then it is easy to deep well pump to extract liquid goods out cargo tank 1.
With reference to Fig. 1-Fig. 4, in the present embodiment, the bottom surface of cargo tank 1 includes noseplate 11, rear bottom plate 12, left bottom plate 13
With right bottom plate 14, the noseplate 11, rear bottom plate 12, left bottom plate 13 and right bottom plate 14 are from cargo tank bottom edge to collection liquid trap
Side is tilted.Noseplate 11, rear bottom plate 12, the plan-position schematic diagram of left bottom plate 13 and right bottom plate 14 refer to Fig. 5.
In the present embodiment, as shown in figure 3, the angle of inclination of the relative level of the noseplate 11 is α 1, α 1 scope
It is 0 ° of 1≤1 ° of ＜ α；Preferably 0.5 °.As shown in figure 3, the angle of inclination of the relative level of rear bottom plate 12 is α 2, α 2 model
It is 0 ° of 2≤1.5 ° of ＜ α to enclose；Preferably 1 °.As shown in figure 4, the angle of inclination of the relative level of left bottom plate 13 is β 1, β's 1
Scope is 0 ° of 1≤4 ° of ＜ β；Preferably 2 °.As shown in figure 4, the angle of inclination of the relative level of right bottom plate 14 is β 2, β's 2
Scope is 0 ° of 2≤4 ° of ＜ β；Preferably 2 °.
The reasons why above-mentioned optimized angle is used in the utility model is as follows.The rear bottom plate 12 is 1 ° with horizontal plane angle
Reason is：The general stern inclination angle of liquefied gas carrier under sail is about 0 °~1.5 °, decision design angle be 1 ° can avoid because
Inclining for stern causes liquid goods to be deposited in collection liquid trap rear area；Similarly the left bottom plate 13 and right bottom plate 14 are with horizontal plane angle
2 ° of the reason for are：The general heel of liquefied gas carrier under sail is about 0 °~4 °, decision design angle be 2 ° can avoid because
Liquid goods is caused to be deposited in collection liquid trap right and left region for heel.Seldom there are the feelings of trim by head in operation in general liquefied gas carrier
Condition, in order to prevent extreme case, the noseplate 11 is set to 0.5 ° with horizontal plane angle, and then reaches and do not influence volume of compartment
Effect.
With reference to Fig. 1, because stern inclines liquefied gas carrier under sail, collection liquid trap 2 is close to the stern position of cargo tank 1.
In summary, the utility model Type B independence rhombus cargo tank polycrystalline substance, improves the operating efficiency of deep well pump,
Shorten the time in port discharge.So, the utility model effectively overcome some practical problems of the prior art so as to
There is very high value and use meaning.
Above-mentioned embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited
Type.The utility model also has many aspects to be improved on the premise of without prejudice to overall thought, for being familiar with this technology
