Embodiment
In order to further illustrate principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, it is the structural representation of the utility model low-temperature tank container.This low-temperature tank container 10 comprises tank body 11, framework 12 and and the pipe-line system of outwards drawing in this tank body 11.
Framework 12 comprises front end frame 121, back-end box 122, is connected to top beam of laterally 123 between front end frame 121 and back-end box 122 top, and, be connected to the bottom side beams 124 between front end frame 121 and back-end box 122 bottom, above-mentioned front end frame 121, back-end box 122, top beam of laterally 123 and bottom side beams 124 are encircled into the said frame 12 can holding large-sized object.
Tank body 11 is placed in said frame 12, the interlayer 113 that this tank body 11 comprises inner housing 111, frame 112 and is formed between inner housing 111 and frame 112, and this interlayer 113 can be vacuum sandwich.
Pipe-line system is positioned at the side-lower near tank body 11 ear end face.Please merge with reference to figure 1 and Fig. 2, Fig. 2 is the partial enlarged drawing in Tu1Zhong A district.Pipe-line system comprises pipeline structure 13 and valve arrangement 14, and this valve arrangement 14 to be arranged on pipeline structure 13 and to be positioned at outside tank body 11.This pipeline structure 13 comprise mainly be arranged in inner housing 111 inside internal pipeline 131, arrange Sandwich pipeline 132 in interlayer 113 and be arranged in the external pipe 133 of frame 112 outside, Sandwich pipeline 132 is communicated with internal pipeline 131 and external pipe 133.In the side-lower space of external pipe 133 between framework 12 and tank body 11.
In order to export the gas in tank body 11, internal pipeline 131 one end is in open state, and the other end is connected with Sandwich pipeline 132.And one end that this internal pipeline 131 is in open state is arranged on the liquid gas bottom the inner housing 111 of tank body 11 ear end face so that in emptying tank.This internal pipeline 131 is from the bottom of inner housing 111 to extending near the direction of back-end box 122 until its other end passes from the ear end face of this inner housing 111 and stretches in interlayer 113 and be connected with Sandwich pipeline 132, and the connected node 135 of internal pipeline 131 and Sandwich pipeline 132 is positioned at the interlayer that inner housing 111 rear end and frame 112 rear end are formed.
Sandwich pipeline 132 extends to the direction away from back-end box 122 from the one end be connected with internal pipeline 131 (i.e. connected node 135 place) along the appearance profile of inner housing 111, and after extension certain distance, bending is to downward-extension until its other end passes frame 112 is connected with external pipe 133.Herein, Sandwich pipeline 132 extends to the direction away from back-end box 122 after the connected node 135 with internal pipeline 131 turns round downwards again.This Sandwich pipeline 132 need extend certain length to ensure that this Sandwich pipeline 132 has enough length in interlayer 113, avoids the anxious sharp cooling of the liquefied gas at low temp in pipeline and gasifies.
One end of external pipe 133 is connected with Sandwich pipeline 132 in the outside of frame 112, and the other end is handling liquid mouth 134.External pipe 133 extends from the joint with Sandwich pipeline 132 to the backward direction near back-end box 122 of downward-extension one segment distance, until the handling liquid mouth of its one end stretches out the ear end face of frame 112, this external pipe 133 is made to comprise two-part, i.e. bending part pipeline 133a and the horizontal pipe 133b that extends in the horizontal direction.As shown in Figure 3, Fig. 3 is the rear structure schematic diagram of the utility model low-temperature tank container.The back-end box 122 of this low-temperature tank container comprises two parallel columns 1221, connects the end upper beam 1222 on two column 1221 tops and the end underbeam 1223 being connected two column 1221 bottoms, this handling liquid mouth 134 stretches in this back-end box 122, more specifically, as shown in Figure 1, back-end box 122 has an exterior edge face 122b extended along tank body short transverse away from tank body near tank body and along the interior edge face 122a and that tank body short transverse extends, and this handling liquid mouth 134 is between interior edge face 122a and exterior edge face 122b.In addition, this handling liquid mouth 134 also can not exceed interior edge face 122a, and is positioned at the side-lower region that back-end box 122 formed with frame 112.
Continue referring to Fig. 1, the valve arrangement 14 for loading and unloading liquid is arranged on the external pipe 133 of the side-lower near tank body 11 ear end face, and more specifically, this valve arrangement 14 is arranged on the horizontal pipe 133b of this external pipe 133.
The pipeline structure of handling liquid is arranged on the side-lower near tank body ear end face by low-temperature tank container of the present utility model; and valve arrangement is also arranged on the above-mentioned pipeline structure of the side-lower of tank body ear end face; make to increase tank case volume; go back Protective valve gate apparatus simultaneously, make transport safer.
The handling liquid mouth of pipeline structure of the present utility model is arranged on the rear portion of low-temperature tank container, is convenient to user and arranges handling liquid flexible pipe, the requirement to space, place when reducing use.
Pipe-line system of the present utility model is arranged in the side-lower space between tank body and framework, take full advantage of the remaining space of tank body surrounding in frame structure, the low-temperature tank container structure making external dimension limited by standard is in the low-temperature tank container of equal external form, tank body size becomes large, and useful load increases.
These are only better possible embodiments of the present utility model, and unrestricted protection domain of the present utility model, all utilization the utility model specifications and the change of the equivalent structure done by accompanying drawing content, be all included in protection domain of the present utility model.
