The vacuum unloading and conveying device of automatically-controlled tank car has the advantages of advanced technology and stable operation, is applicable to long-term continual operation and causes no damage even in emergency condition of vacuated medium, thus the device is very applicable to the unloading and conveying of various inflammable, explosive, corrosive liquid medium of petrochemical industry, chemical industry and power industry. Moreover, the vacuum unloading and conveying device of automatically-controlled tank car adopts automatic control and can such by vacuum and output by boosting without any residual of unloading medium.
Description
Technical field
The utility model relates to the unloading of a kind of groove tank car and sweeps the storehouse feedway, particularly a kind of automatic guidance groove tank car vacuum unloading conveying device of the integration pump formula of being made up of vacuum reservoir and vacuum of can the vacuum suction again can supercharging exporting of automation control.
Background technology
Groove tank car de-ballast pump is one of major equipment of liquid medium groove tank car unloading conveying, is widely used in industry departments such as oil, chemical industry, electric power, metallurgy, environmental protection, sewage disposal, food, pharmacy, syntheticfibres, mining, papermaking, building.The measure of extensively adopting in the groove tank car unloading at present has:
Self-priming pump: its principle of work is to utilize the medium that prestores in the pump chamber will suck in the cyclic process repeatedly under the effect of pump after air wrapped folder in the pump chamber discharges, could normal operation, and its shortcoming is that evacuation time is long, efficient is low.Because of defective (it is low the to suct vacuum height) restriction that is subjected to change can not unload the bigger chemical medium of density.There is very big disaster hidden-trouble when unloading the medium of inflammable, explosive, easy gasification.
Positive displacement pump: positive displacement pump comprises plunger reciprocating pump, membrane pump, lobe pump, screw pump and gear type pump etc.Because of its friction coefficient is bigger, parts are easy to wear, so operating efficiency is low, service life is low.
Centrifugal pump: use centrifugal pump spron jar to need the vacuum pump subsidy, in the unloaded operation, vaporize easily, just need repeated multiple times to start vacuum pump, restart centrifugal pump work again with the gas sucking-off as medium.
The common defects that above-mentioned technological measure exists also has: 1, must someone guard the Control work process in the equipment operation, will cause equipment idle running damage equipment as careless slightly, as discharged be that therefore inflammable and explosive medium also can lead to fire accident; 2, medium unloading back residual quantity is big, and consequent economic loss is also very big.
The utility model content
The utility model is at above-mentioned problems of the prior art, provide a kind of stable, automation control can vacuum suck again the automatic guidance groove tank car vacuum unloading conveying device of can supercharging exporting and unload the medium noresidue by what vacuum vessel jar and vacuum pressurizer were formed, solve the inflammable and explosive medium difficulty of unloading in the prior art, unloaded problems such as back medium residual quantity is big.
The technical solution of the utility model is as follows:
Comprise the vacuum vessel jar, the vacuum vessel jar is provided with inlet ductwork, export pipeline and vacuum interface; The vacuum vessel jar links to each other by connection pipe with the vacuum pressurizer; The vacuum pressurizer is provided with aspirate tube and freeing pipe, and aspirate tube and freeing pipe are tightly connected by the two-bit triplet electromagnetic valve respectively and between the connection pipe.
Also be provided with level transducer in the described vacuum vessel jar.
Described vacuum vessel jar is provided with import pipe valve and outlet pipe valve.
Described vacuum pressurizer adopts liquid-ring vacuum pump as working host.
Described liquid-ring vacuum pump can adopt other scribing formula vacuum pump, diaphragm-type vacuum pump, screw vacuum pump, Roots vaccum pump and centrifugal vacuum blowers that do not have the malleation compression function to substitute.
The utility model has the advantages of as follows:
1, advanced technology, stable, be suitable for long-term running continuously, can not damage even under the accident condition that medium is found time, turn round yet, therefore this device is very suitable in petrochemical industry, chemical industry and the unloading of power industry enterprise, passes on all kinds of inflammable and explosive and corrosive liquid body mediums.
2, automation control can vacuum suck again and can supercharging export the noresidue of unloading medium.
