Abstract

The present invention relates to a kind of internal pump low-temperature storage tank.There is manhole on tank body with heat-insulation layer, manhole removable seal insulation flange, tank body inner bottom part has pump pond, immersed pump is fixed with pump pond, and immersed pump liquid outlet is sealed with drain pipe by connecting tube and fixed, and described insulation flange is stretched out in drain pipe sealing.Its simple structure, it is convenient to use without precooling.

Description

A kind of internal pump low-temperature storage tank
Technical field
The present invention relates to a kind of low-temperature storage tank, the internal pump low-temperature storage tank of more particularly to a kind of LNG.
Background technology
At present, in LNG gas stations, low-temperature storage tank is independently used with immersed pump, and low-temperature storage tank is used merely to Storage LNG, immersed pump is arranged in pump pond, and the two is connected by vacuum pipe.Specific connected mode is, low-temperature storage tank goes out Liquid mouthful is connected by vacuum pipe with the inlet in pump pond, storage tank gas phase mouth and Beng Chi gas returning ports UNICOM, and low-temperature storage tank frame It is located on buttress, to ensure to require there is certain difference in height between the two, to ensure the net positive suction head of immersed pump.Liquid is from storage tank In middle inflow pump pond, precooling is carried out to immersed pump, after reaching pre- cool condition, immersed pump could be started.LNG fills the stand-by period Long, gas station process system is complicated.
The content of the invention
In order to overcome the shortcoming of prior art, the present invention to provide a kind of internal pump low-temperature storage tank.Its simple structure, without pre- It is cold, it is convenient to use.
The technical scheme adopted by the invention to solve the technical problem is that：There is manhole on tank body with heat-insulation layer, manhole can Dismounting sealing thermal insulation flange, tank body inner bottom part has pump pond, is fixed with immersed pump in pump pond, immersed pump liquid outlet by connecting tube with Drain pipe sealing is fixed, and described insulation flange is stretched out in drain pipe sealing.
The present invention has following advantages：1), because immersed pump is built in storage tank, it is possible to achieve low-temperature storage tank holds to low temperature Device fills the function of LNG；2), immersed pump is immersed in LNG always, without carrying out precooling to pump again, it is ensured that more than immersed pump cavitation Amount, can at any time open pump, shorten the filling time, improve efficiency；3), due to there is manhole, convenient disassembly is repaired.It is latent by what is shaken Liquid pump lifting is fixed on flange, and pump discharge pipeline and control cable are drawn into storage tank, realizes immersed pump in tank inside Reasonable installation；4) gas station process system, is optimized, pump pond, section of tubing and valve etc. is saved, manufacturing cost is saved.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is schematic diagram of the present invention.
Specific embodiment
As shown in figure 1, have manhole 10 on the tank body 1 with heat-insulation layer 9, the removable seal of manhole 10 insulation flange 8, tank body 1 Inner bottom part has pump pond 2, and pump pond 2 is interior to be fixed with immersed pump 3, and the liquid outlet of immersed pump 3 is sealed with drain pipe 7 by connecting tube 4 and fixed, Drain pipe 7 is sealed and stretches out described insulation flange 8.
The outer fixed cable sleeve 5 of described connecting tube 4, one end of cable sleeve 5 is fixed with the cable port of immersed pump 3, the other end Sealing is stretched out in described insulation flange 8, cable sleeve 5 immersed pump cable 6.
