Abstract
The invention discloses a filling device for a liquid tank car. The filling device comprises a centrifugal pump and a motor, wherein a liquid inlet header pipe is arranged at the front end of the centrifugal pump; the front end of the liquid inlet header pipe is connected with a storage tank liquid outlet valve and a storage tank liquid return valve; an outlet pipeline is arranged behind the centrifugal pump; and an outlet blow through valve and an outlet valve are arranged on the outlet pipeline in sequence. According to the filling device for the liquid tank car, booster filling is adopted, so that the filling pressure is increased to about 0.5 Mpa from 0.1 Mpa below; the tank car continuously releases for ensuring the low pressure, so that discharge waste is reduced; the filling time is shortened by about 70%, so that the operating efficiency is improved; when liquid argon is filled, the reduced released gas can generate remarkable benefit; besides, the filling device for the liquid tank car is simple in structure and operation and low in production cost.
Description
Technical field
The present invention relates to a kind of charging device of liquid tank car.
Background technology
Air separation unit tank car charging system is the gravity flow charging system that industry is generally used, and system equipment is simple in structure, and is easy to use, but this system's filling process is consuming time longer, 20 cubes of liquid tank cars, and the time that on average fills, operating efficiency was lower about 3 hours.In addition, fill mode by gravity flow, must open tank car in the filling process and diffuse valve, caused certain waste, 20 cubes of tank cars filled about 3 hours according to the preliminary statistics, the about 1 ton of liquid of loss.
Summary of the invention
Defective in view of above-mentioned prior art exists the objective of the invention is to propose a kind of raising that in liquid tank car filling process, utilizes charge pressure, stops continuing in the filling process and diffuses, and shortens filling the time, improves the filling equipment of operating efficiency.
The object of the invention; To be achieved through following technical scheme: a kind of liquid tank car charging device; Comprise centrifugal pump and motor, said centrifugal pump front end is provided with the feed liquor house steward, and said feed liquor house steward front end returns the liquid valve with storage tank liquid valve and storage tank and is connected; Be provided with outlet conduit behind the said centrifugal pump, be provided with outlet blow through valve and outlet valve on the said outlet conduit successively.
The technical scheme that the present invention further limits is: said outlet valve rear side is provided with and fills bayonet socket.
Further, aforesaid liquid tank car charging device is provided with shutoff valve before the said centrifugal pump.
Further, aforesaid liquid tank car charging device, the bearing place of said centrifugal pump is connected with blanketing gas.
The present invention, its outstanding effect is: of the present invention practical, it is remarkable to use the back effect; After the design adopts supercharging to fill; Charge pressure rises to about 0.5MPa from being lower than 0.1MPa, and tank car need not taked in order to guarantee low pressure to continue to diffuse, and has reduced the discharging waste; The time of filling can shorten about 70%, has improved operating efficiency; When filling liquid argon, the diffusing gas and can produce very considerable benefit of minimizing.And simple in structure, easy and simple to handle, productive costs is low.
Following constipation closes the embodiment accompanying drawing, and specific embodiments of the invention is done further to detail, so that technical scheme of the present invention is easier to understand, grasp.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
A kind of liquid tank car charging device that present embodiment provides makes the charging device of pump supercharging with original into from streaming system, comprises a low-temperature centrifugation pump 1 and motor, is the power resources of this device; And the bearing director of centrifugal pump is led to blanketing gas, to guarantee that cryogenic liquid does not produce the freeze damage bearing.Front end at centrifugal pump has set up a feed liquor house steward 2; Simultaneously, feed liquor house steward's front end and storage tank liquid valve 3 and storage tank return liquid valve 4 and are connected.Above-mentioned two valves keep normally open at ordinary times, can guarantee that liquid circulation flow is logical.Simultaneously, present embodiment has also been set up shutoff valve 5 one before centrifugal pump, to be convenient to repair and maintenance and the service life that prolongs valve.An outlet conduit 6 is set behind centrifugal pump, is provided with outlet blow through valve 7 and outlet valve 8 on this outlet conduit successively, can discharge, do not produce cavitation erosion when guaranteeing operation residual air in the pipeline.Wherein, be provided with at the outlet valve rear side and fill bayonet socket 9, can utilize to fill that flexible pipe is realized and being connected of liquid tank car, make the liquid after the supercharging be conveyed into tank car through flexible pipe.
