Description
Technical field
The utility model belongs to technical field of chemical production equipment, and in particular to one kind is for transporting chemical industry corrosive fluid
The device that groove tank car is unloaded.
Background technique
Often there is the very strong fluid of many corrosivity to transport in chemical production process by groove tank car, such as strong acid, highly basic,
And transport each production unit and necessarily have process of unloading, it unloads in process in tradition, corrosive fluid passes through hose of unloading
It is directly connect with centrifugal pump inlet pipeline, centrifugal pump is opened when unloading, fluid foods are by connecting pipe after centrifugal pump is pressurized
It is transported to storage container.However the drawbacks of such method first is that: the air in hose of unloading can not be discharged, and air will be with " small
The form of bubble " exists together with fluid foods, and this " minute bubbles " when flowing near impeller because of negative pressure near impeller
It generates and acceleration shock impeller surface, to generate " cavitation " to centrifugal pump impeller, if things go on like this impeller failure accelerates, and makes to be centrifuged
Pump transfer efficiency is greatly reduced, and centrifugal pump is unable to reach design discharge and lift when serious, so that tradition be made to unload the time used
Extend；Drawback second is that: unload in tradition and unload in vehicle speed and groove tank car height of materials in process inversely, i.e., in groove tank car
Liquid level is lower, and fluid foods flow velocity in pipeline is slower；Drawback third is that: when material liquid level is closer to bottom in groove tank car, and unload
The case where fluids within pipes material of vehicle centrifugal pump connection will appear " non-full pipe ".Because air enters in pipeline, unload at this time from
Heart pump operation sound and vibration can become larger, it is necessary to stop pump operation of unloading, result in groove tank car bottom in this way and unload in hose
It always is to have portion of residual material that can not be transported to storage container by centrifugal pump, these salvage stores are when unloading hose-off
It can leak out, to corrode ground and neighbouring chemical industry equipment.So the drawbacks of traditional slot tanker vehicle unloading device, is first is that easy to damage
Unloading pump, second is that the time of unloading either needs people to frequently switch on pump discharge drain tap slowly, third is that there is salvage stores always
It can not unload net.
Summary of the invention
Unloading unit described in the utility model is suitable for transporting unloading for chemical industry strong corrosive fluid groove tank car, makes groove tank
Vehicle and the remaining strong corrosive material unloaded in pipeline are by being transported to specified containers storage through delivery pump after the device.Both it avoided
Corrosive fluid material substantially increases because leakage corrosion ground and device achieve the purpose that economize on resources again and unloads speed
Degree, and prevent unloading pump because of impeller failure caused by " cavitation ".
Pressure-equalizing passageway described in the utility model connection cabinet and storage container, no setting is required any valve, with stream
Body material enters the intracorporal air of case and can be automatically drained out, and does not need any manual operation.
The content of the present invention provides a kind of device unloaded for transporting chemical industry corrosive fluid groove tank car, the device
The complete noresidue formula of material in transport corrosive fluid groove tank car may be implemented to unload, both avoided corrosive materials leakage corrosion
Ground, in turn avoids the waste of resource, while greatly improving and unloading vehicle speed and unloading pump normal operation rate.The present invention is particularly suitable
In unloading for strong corrosive fluid groove tank car.
Purpose of the utility model is realized as follows:
A kind of device unloaded for transporting chemical industry corrosive fluid groove tank car, it includes: screwed fitting, charging adapter tube
Mouth, discharging pipe nozzle, pressure-equalizing pipe, connecting pipe, unloads driver's valve, pipelined filter, unloading pump, pump discharge pipe at cabinet
Road, storage container, groove tank car.
The bottom of box is provided with discharging pipe nozzle in the device, and discharging pipe nozzle is connect through connecting pipe with driver's valve is unloaded,
It unloads driver's valve to connect with pipelined filter, pipelined filter is connect with pump discharge pipeline, pump discharge pipeline and storage container
Connection.
The top of the box at the top of pressure-equalizing pipe and storage container through connecting.
The top of the box is provided with charging pipe nozzle, feeds and is provided with screwed fitting in pipe nozzle.
The junction of the pipelined filter and pump discharge pipeline is provided with unloading pump.
When operation, chemical industry corrosive fluid material is connect by tank car hose screwed fitting of unloading with the device screwed fitting
Afterwards, it opens groove tank car to unload valve, fluid foods flow into cabinet through charging pipe nozzle (volume and size are by being calculated).Case
In vivo and groove tank car air of unloading in pipeline by pressure-equalizing passageway is discharged to storage container automatically, to guarantee that fluid foods connect
Fluid foods are full of until all air are discharged in rear box by pressure-equalizing passageway in afterflow cartonning body, driver is unloaded in unlatching
Valve, fluid are unloaded driver's valve and pipelined filter and are flowed into unloading pump, and unloading pump is started, and pass through pump discharge for fluid foods are defeated
Pipeline is to storage container.
The volume V of the cabinet is more than or equal to (groove tank car length of tank L × groove tank car is unloaded after outer diameter tube D rounding
Square+unload hose volumes V1).Specially such as L=9 meter, D=0.089 meter, V1=0.2m3, V >=9*0.1+0.2, then V >=1.1m
³.After guaranteeing that unloading pump is out of service, salvage stores can be fully entered in cabinet in groove tank vehicle tank and hose of unloading, and be taken off
It starts discharging non-spill after vehicle hose.
The determination of box height H must unload outlet valve pipe apart from ground in conjunction with live actual installation position, groove tank car
Height H1, plan range ground level H2, H1 and H2 height is differed by more than equal to 200mm on screwed fitting 1, i.e. and H1-H2 >=
200mm.To guarantee that fluid foods can continuously flow into cabinet from groove tank car.
Pressure-equalizing pipe is served only for cabinet and storage container connection, and its role is to balance groove tank car and its pipeline of unloading
The interior pressure in cabinet and storage container, while can prevent from (unloading speed more than unloading pump because material flow of unloading is too fast again
Degree) and the dangerous of spilling occurs, even if it is also the container for being flowed into the storage material by the equalizing main that fluid foods, which overflow,
It is interior, the not mountable any valve of the equalizing main.
Pipelined filter guarantees to prevent from unloading without large granular impurity from the fluid foods flowed into groove tank car in unloading pump
Pump blocking.
After unloading, i.e., after unloading pump stops, salvage stores is can not be defeated by unloading pump in groove tank car and pipeline
Cabinet can be flowed directly into the case where sending, and disengage screwed fitting after material unloads only, again crawl unloading pump, it will be remaining in cabinet
Material is transported to storage container, that is, after-etching fluid is avoided to flow to out-of-bounds
Corrosion is generated, and fluid foods in groove tank car can be made to unload completely only.
