The supravasal valve of tank top allows the gas pressure of the tank inside upper end close to tank car to be sequentially delivered to close to delivery pump
In storage tank, so that gas pressure increases and keeps normal feed in the storage tank of delivery pump, and close to the tank inside of tank car
The gas pressure of upper end is conducive to further discharging after reducing；4., when close to delivery pump storage tank in gas pressure be reduced to deficiency
It when being fed, closes and connects the two neighboring supravasal valve of tank top, open and connect on two neighboring tank bottom conduit
Valve, the gravitational difference that silicon tetrachloride liquid position to rely on difference is formed successively flow to close delivery pump from the storage tank close to tank car
Storage tank, and form pressure in the storage tank close to delivery pump and continue to be fed, until discharging is completed.
To be further that the present invention is suitable for the application of, delivery pump uses canned motor pump, and shield pump structure eliminates conventional centrifugal pump
The sealing device for rotary shaft having, therefore can accomplish complete No leakage.Canned motor pump is existing equipment, is had out on the shell of canned motor pump
It closes, canned motor pump is connect by switch with external power supply, and those skilled in the art can select corresponding model to be attached and control
System.
The continuity Homogeneous charge structure for unloading silicon tetrachloride storage tank under car state and method provided by the invention have positive
Effect：It is made of tank car, more storage tank cascaded structures, conduit, valve and delivery pump, structure is simple；It is unloaded when use using tank car
It is fed after material in the gas pressure that storage tank internal upper part is formed, or the gravitational difference formed using alternate position spike is close to delivery pump
Storage tank in formed pressure and continue to be fed, realize in the case where unloading car state continuous uniform feed intake, do not stop production and influence to produce.
The Detailed description of the invention present invention will be further described in conjunction with attached drawing, please refer to attached drawing：
It is attached that Fig. 1 shows structural schematic diagrams of the invention.
Attached structure shown in FIG. 1 includes：Tank car 1, valve 2, conduit 3, storage tank 4, delivery pump 5.
The specific embodiment continuity Homogeneous charge structure provided by the invention for unloading silicon tetrachloride storage tank under car state and
Method is made of tank car 1,4 cascaded structure of more storage tanks, conduit 3, valve 2 and delivery pump 5, wherein more 4 cascaded structures of storage tank are by 2
~5 storage tanks 4 are in series, and 4 numbers of storage tank then influence continuity Homogeneous charge less than 2, and 4 numbers of storage tank are greater than 5 then shadows
Ring installation；Storage tank 4 close to tank car 1 is connected to tank car 1 by conduit 3, and one end of conduit 3 is connected to 1 bottom of tank car, conduit 3
The other end is connected to 4 top of storage tank, is lower than 0.5~3 meter of 1 bottom of tank car at the top of storage tank 4, then influences discharging less than 0.5 meter, be greater than
