Description
Technical field
The utility model relates to the filling device of oxygen.
Background technique
The filling device of oxygen comprises large oxygen tank and little oxygen tank, the filling device of oxygen i.e. large oxygen tank are to the device of little oxygen tank delivery of oxygen liquid, large oxygen tank has output pipeline and connects little oxygen tank, and little oxygen tank has discharge conduit, arranges discharge conduit in order that fill with and keeps certain purity into the oxygen in little oxygen tank; In prior art, discharge conduit directly leads to air, has the shortcoming wasted raw material.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides a kind of filling device of oxygen saved material, cut the waste.
The technical solution of the utility model is achieved in that a kind of filling device of oxygen, comprise large oxygen tank and little oxygen tank, large oxygen tank has output pipeline and connects little oxygen tank, it is characterized in that: little oxygen tank has recovery channel, described recovery channel connects again the bottom of large oxygen tank, on large oxygen tank, have discharge conduit.
Say further, in the middle of described recovery channel, also pressure pump is installed.
Say to also have cooling device in the middle of described recovery channel further.
The beneficial effects of the utility model are: the filling device of such oxygen has the advantage of saving material, cutting the waste; Also pressure pump is installed in the middle of described recovery channel, also has cooling device in the middle of described recovery channel, there is the advantage of better effects if.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present utility model.
Wherein, 1, large oxygen tank 2, little oxygen tank 3, output pipeline 4, recovery channel 5, discharge conduit 6, pressure pump 7, cooling device.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, a kind of filling device of oxygen, comprises large oxygen tank 1 and little oxygen tank 2, large oxygen tank 1 has output pipeline 3 and connects little oxygen tank 2, it is characterized in that: little oxygen tank 2 has recovery channel 4, described recovery channel 4 connects again the bottom of large oxygen tank 1, on large oxygen tank 1, have discharge conduit 5.
The remaining oxygen that such recovery channel is collected can be got back to again in large oxygen tank, and the nitrogen of the inside presents gaseous state, discharges, can keep the purity of oxygen inside large oxygen tank, have advantage of the present utility model from discharge conduit.
Say further, in the middle of described recovery channel 4, pressure pump 6 is also installed.
Say to also have cooling device 7 in the middle of described recovery channel 4 further.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed in the scope of the claims of the present utility model.
