Description
Technical field
The present invention relates to the unloading of a kind of groove tank car and sweep the storehouse feedway, particularly a kind of vacuum unloading conveying device of automatic control tank trunk of the integration pump formula of can the vacuum suction again can supercharging exporting that is formed by vacuum reservoir and vacuum 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 the 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 at present groove tank car unloading has:
Self-priming pump: its principle of work is after utilizing the medium that prestores in the pump chamber will suck air wrapped folder in the pump chamber in the iterative cycles process under the effect of pump to discharge, could work, and its shortcoming is that evacuation time is long, efficient is low.Because defective (it is low the to suct vacuum height) restriction that is subjected to change can not unload the larger chemical medium of density.There is very large 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 its friction coefficient is larger, parts are easy to wear, so operating efficiency is low, service life is low.
Centrifugal pump: use centrifugal pump spron tank to need the vacuum pump subsidy, in the unloaded operation, vaporize easily such as medium, just need repeated multiple times startup vacuum pump with the gas sucking-off, restart again centrifugal pump work.
The common defects that above-mentioned technological measure exists also has: 1, equipment is in service must someone guard the control working process, will cause equipment idle running damage equipment as careless slightly, and such as unloading is that therefore inflammable and explosive medium also can lead to fire accident; 2, residual quantity is large after the medium unloading, and consequent economic loss is also very large.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provide a kind of stable, automation control by can vacuum sucking again of vacuum vessel tank and vacuum boosting installation composition can supercharging output and unload the vacuum unloading conveying device of automatic control tank trunk of medium noresidue, solved the inflammable and explosive medium difficulty of unloading in the prior art, the problems such as the medium residual quantity is large after unloading.
Technical scheme of the present invention is as follows:
Comprise the vacuum vessel tank, the vacuum vessel tank is provided with inlet ductwork, export pipeline and vacuum interface; The vacuum vessel tank links to each other by connection pipe with the vacuum boosting device; The vacuum boosting device 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 tank.
Described vacuum vessel tank is provided with import pipe valve and outlet pipe valve.
Described vacuum boosting device 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-type vacuum pump, Roots vaccum pump and centrifugal vacuum blowers that do not have the malleation compression function to substitute.
Advantageous effect of the present invention is as follows:
1, advanced technology, stable, be suitable for long-term continuous operation, 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 electric power industry enterprise unloading, 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.
