Description

Integrated liquefied petroleum gas (LPG) ground filling apparatus

The utility model relates to a kind of liquefied petroleum gas (LPG) and stores the filling station device therefor, and especially small-sized liquor ratio petroleum gas is stored the used liquor ratio petroleum gas of filling station and stored and filling apparatus.

Show according to Domestic market investigation in recent years, present domestic liquefied petroleum gas (LPG) is stored filling station forward two poles development, the one, to the development of large-scale station, volume from several thousand to last ten thousand stere, send out the liquid gas station of company as the sky, Hubei, this needs very big fund input and takies more land area, and the one, to the development of small-sized station, little to 100 cubic metres to 10 cubic metres.We know, an area is built a plurality of large-scale stations and be there is no need owing to market capacity is limited, and directly transport small steel cylinder also is unsafe, therefore this just need build small-sized station, small-sized station also only need be built as the small towns in some place, along with the development with the eco-friendly car of liquefied petroleum gas (LPG) instead of gasoline is popularized, each is big, in, highway side, small city also needs to build a lot of small-sized gas stations, compare the fund input of much less with large-scale station and take less land area though small-sized gas station has, but because employed liquor ratio oil gas-reservoir preface equipment is that basin and filling apparatus and raffinate recovering device establish one's own system on the Domestic market, disperse independent relatively, still need to take certain fund input and land area, this just needs more fund input, even in the small towns to the city of inch of land such as gold, it also is not all right occupying cultivated land more, build small-scale terrestrial station fitting operation complexity simultaneously, the cycle is longer relatively, and the storage of the present liquid gas station use of China that Here it is and jar are than equipment actuality.

The purpose of this utility model is to be to provide a kind of quick for installation, easy and simple to handle, and less investment is taken up an area of few, and the liquefied petroleum gas (LPG) of using peace golden collection storage, can and small steel cylinder raffinate to be recovered as one simultaneously stores filling apparatus.

For achieving the above object, integrated liquefied petroleum gas (LPG) of the present utility model ground filling apparatus is by liquefied petroleum gas container, various pipe valves, the hydrocarbon pump, metallic base, valve box is formed, basin, the hydrocarbon pump, valve box, pipeline all is fixed on the metallic base, valve box is fixed on position on metallic base one side, the hydrocarbon pump is fixed on valve position in the same side, metallic base is by two crossbeams, three connect fixedly longeron composition of longeron and two basins, the hydrocarbon pump mounting base that three girders are formed is equipped with in neutral position, the one crossbeam outside, upper the putting of the same side of this crossbeam is equipped with the valve box scaffold, their size respectively with the hydrocarbon pump seat, adapt at the bottom of the valve box, basin fixedly is fixed with four backing plates on the longeron, all be drilled with screw on each backing plate, fixedly longeron size spacing and basin base adapt, the basin bottom is connected to gas, liquid phase pipeline, gas, liquid phase pipeline, with valve, the hydrocarbon pump connects into loading and unloading, can and raffinate reclaim line, maimed recovery valve and filling valve are installed in the valve box

Basin in the utility model only is applicable to small capacity, and its volume is less than 50 cubic metres.

Because the formula ground filling apparatus that becomes one is combined in storage and can and raffinate reclaiming system preferably, compact structure, saved more land area, having removed the part pipeline simultaneously from installs and foundation of civil work, fitting operation is more simple and convenient, compare with former small-scale terrestrial station, fund input more economizes, also meet simultaneously relevant security regulations requirement, less investment, instant effect can replace society fully and go up the dangerous way of indivedual simple and easy filling machines that adopted for reducing investment outlay with tank car can small steel cylinder, satisfies security needs.The utility model is described in further detail below in conjunction with drawings and Examples.
