Abstract
The utility model relates to a rotating type LNG storage tank which comprises an LNG storage tank body, an outer tank body and a rotating device, wherein a pressure sensor is arranged on the top of the LNG storage tank body, a rotating shaft is fixedly connected to the LNG storage tank body, a gear is fixedly connected to the rotating shaft, a groove opening is formed in a position, corresponding to the LNG storage tank body, of the outer tank body, the diameter of the groove opening is larger than that of the rotating shaft, the rotating device comprises a control box and a rotating chain, the rotating device is fixedly connected to the outer tank body, the rotating chain on the top of the rotating device is connected with the gear in a matched mode, and the control box is fixedly connected with the pressure sensor. According to the rotating type LNG storage tank, liquid in the storage tank can be thoroughly mixed through the rotating type LNG storage tank when pressure of BOG exceeds a critical value so that the effect of pressure reduction can be achieved, zero emission of the BOG can be achieved, and the utilization rate of LNG can be improved.
Description
Technical field
The utility model relates to LNG sledge dress station technical field, especially a kind of rotary LNG storage tank.
Background technology
Along with widespread use and the develop rapidly of domestic LNG, the technology of LNG gas station and application are also at high speed development.At present, the aerating of domestic LNG automobile mainly is to transfer saturated pressure to carry out aerating by the LNG storage tank.But, the LNG Vehicle Fueling Station all needs to transfer saturated pressure for refueling at every turn, because temperature raises, liquid in the LNG storage tank constantly gasifies, the gas of this part gasification should in time be eliminated, in order to avoid the LNG tank inner pressure is excessive, mainly adopt now spray and discharging BOG gas to solve this problem and both polluted environment, increased again the waste of manpower, financial resources and material resources.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of rotary LNG storage tank is provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of rotary LNG storage tank, comprise the LNG storage tank, outer tank body and slewing arrangement, described LNG tank top is provided with pressure sensor, be fixedly connected with S. A. on the described LNG storage tank, be fixedly connected with gear on the described S. A., described outer tank body and LNG storage tank corresponding position have notch, described notch diameter is greater than the S. A. diameter, described slewing arrangement comprises control box and rotary-chain, described slewing arrangement is fixedly connected on the described rotary-chain in outer tank body top and gear is connected, and described control box is captiveed joint with pressure sensor.
Particularly, described notch two ends are equipped with and can change the contactless switch that drives the magnetic patch sense of motion.
Particularly, be provided with lubricated cushion rubber between described LNG storage tank and the outer tank body.
Particularly, the maximum anglec of rotation of described LNG storage tank is 30 degree
The beneficial effects of the utility model are: a kind of rotary LNG storage tank that the utility model provides can be when the BOG gaseous tension surpasses critical value, by rotation LNG storage tank, liquid in the storage tank is mixed, to reach the effect that reduces pressure, realize the zero-emission of BOG, improved the degree of utilization of LNG.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is rotary LNG storage tank schematic diagram of the present utility model;
Fig. 2 is rotary LNG storage tank slewing arrangement schematic diagram of the present utility model.
Among the figure: 1.LNG storage tank, 2. outer tank body, 3. slewing arrangement, 4. lubricated cushion rubber, 11. pressure sensors, 12. S. A.s, 13. gears, 21. notches, 22. contactless switchs, 31. control boxs, 32. rotary-chains.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Such as Fig. 1, shown in Figure 2, a kind of rotary LNG storage tank, comprise LNG storage tank 1, outer tank body 2 and slewing arrangement 3, LNG storage tank 1 top is provided with pressure sensor 11, be fixedly connected with S. A. 12 on the LNG storage tank 1, be fixedly connected with gear 13 on the S. A. 12, outer tank body 2 has notch 21 with LNG storage tank 1 corresponding position, be provided with lubricated cushion rubber 4 between LNG storage tank 1 and the outer tank body 2, notch 21 two ends are equipped with the contactless switch 22 that can change LNG storage tank sense of motion, notch 21 diameters are greater than S. A. 12 diameters, slewing arrangement 3 comprises control box 31 and rotary-chain 32, and slewing arrangement 3 is fixedly connected on outer tank body 2 tops, and rotary-chain 32 and gear 13 are connected, control box 31 is captiveed joint with pressure sensor 11, and the LNG storage tank 1 maximum anglec of rotation is 30 degree.
When pressure in the LNG storage tank 1 surpasses setting value, control box 31 can receive the run signal of pressure sensor 11 transmission, rotary-chain 2 beginning driven gears 13 are moved, the lower LNG of temperature of lower floor is up moved, absorb the BOG gas of gasification, reach the effect of step-down, actv. has prevented from causing rolling because layering occurs the LNG in the LNG storage tank.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification sheets, must determine its technical scope according to the claim scope.
