Alumina powder Container Transport discharge operation technical scheme
Technical field: alumina powder Container Transport discharge operation technical scheme of the present invention is mainly used in freight container long-distance transport and the discharge operation of alumina powder.
Technical background: present stage electrolytic aluminium factory the main dual mode of packed and transported of raw materials for production alumina powder: a kind of is to adopt Polywoven Bag to pack and transport.Namely on alumina producer or storage ground, the ton of alumina powder being packed into pipeline transporter fills in the Polywoven Bag, vehicle in use or train are transported to electrolytic aluminium factory, the ton that alumina powder will be housed with crane fills the aluminium oxide discharge bin that Polywoven Bag winches to electrolytic aluminium factory, bottom with the method for cutting cuts open woven bag flow in the aluminium oxide discharge bin alumina powder.The shortcoming of this kind packed and transported is that Polywoven Bag mostly is disposable use, and packing cost is high.
Packing and the transportation formula of another kind of alumina powder are, adopt the special-purpose collection of train or automobile granular material pot type entrucking transportation, namely on alumina producer or storage ground, pipeline transporter is encased in alumina powder in the tank container of automobile or train cover, be transported to electrolytic aluminium factory, with pipeline air pressure alumina powder be unloaded in the aluminium oxide discharge bin.The shortcoming of this kind packed and transported is the special-purpose tank container of automobile and train, can only load alumina powder, can not load other article of masonry, causes the zero load of automobile and train to return, and causes traffic cost to strengthen.
Summary of the invention: in order to reduce the transport package cost of electrolytic aluminium factory alumina powder, invention provides a kind of brand-new operation technique scheme that reduces the raw alumina powder transportation of electrolysis enterprise and packing cost, it is characterized in that: in alumina producer or storage supply place, with pipeline transporter alumina powder is encased in the square granular material freight container, the square granular material freight container that alumina powder will be housed with train cover is transported to the aluminium oxide storage bin discharge point field of electrolytic aluminium factory, the rectangular container of alumina powder will be housed with hoisting and hanging machinery, be placed on the tilting-type unloading goods inside container platform, the device for discharging of opening container lateral bottom section is discharge port, freight container is tilted to the discharge port direction on tilting-type unloading goods inside container platform, cause the interior alumina powder earial drainage of freight container in aluminium oxide unhurried current discharge bin.
Alumina powder rectangular container hauling operation technical scheme of the present invention, can substitute the packed and transported mode that existing employing plastics ton fills bag weaved transportation alumina powder fully, save packing and have bad luck cost, and the mode of alternative employing special-use vehicle tank car and train tanker vehicle transportation alumina powder, reduce the railway carriage no-load ratio, improve material transportation efficient, reduce traffic cost.
Specific embodiment:
Alumina powder Container Transport discharge operation technical scheme is the hauling operation program of a cover system.
Adopting the alumina powder freight container is the granular material freight container, the gordian technique of this freight container is that the seal request of casing is strict, the pipeline that is provided with at the top of freight container is carried dress feeding mouth and capping, the distolateral section of freight container is provided with hermatic door, and end or the beneath end of container end side seal door are provided with the powdery material unloading device under distolateral of freight container, i.e. the granular material feed opening.
Its hauling operation process is:
In alumina producer or aluminium oxide storage supply place, with pipeline transporter the oxidation powder is encased in the granular material freight container, and capping is moistureproof.
With weight-lifting equipment crane or fork truck, the container hanging that alumina powder is housed is placed on the container flat plate railway carriage of field, Railway station.
Through the railway long distance transportation, the freight container that alumina powder is housed is transported to the aluminium oxide discharge terminal field of electrolytic aluminium factory.
This discharge terminal field is provided with the discharging of alumina powder specific purpose container and conveying system device, and this system and device the elevator machinery equipment institute such as is had bad luck by tilting-type unloading goods inside container platform, alumina powder unhurried current discharge bin and alumina conveying appliance, lifting and consisted of.
Load factory of special station at aluminium oxide, containerize and unload specialized equipment crane or fork truck, the freight container that alumina powder is housed is unloaded from train wagon:
At this moment, the freight container of alumina powder can will be housed with hanging device directly, be placed on the tilting-type unloading goods inside container platform, carry out the aluminium oxide discharging.
At this moment, also available hanging device freight container that alumina powder will be housed carries out the railway carriage unloading operation, freight container is transported to appointment unloading apron place to be stacked, railway carriage after unstowing is loaded the freight container of packed into other goods such as aluminium ingot, fast railway carriage is transported to out the field, Railway station, to improve rail transportation efficiency.
After the alumina powder freight container will be housed be seated on the tilting-type unloading goods inside container platform, open freight container powdery material unloading door, open the discharge port sealing arrangement, alumina powder is flow in the alumina powder unhurried current discharge bin.
When the alumina powder discharge in the freight container reduces, start tilting-type unloading goods inside container platform hydraulic jacking system, drive tilting-type unloading goods inside container platform, drive freight container and be tilted to discharging end, cause the alumina powder in the freight container, all inflow is unloaded in the alumina powder unhurried current discharge bin.
After the alumina powder in the freight container all unloads only, the change-over valve of tilting-type unloading goods inside container platform hydraulic jacking system is opened, make tilting-type unloading goods inside container platform and freight container return to level attitude, again with equipment such as lifting or fork trucks, with the container crane after unstowing from tilting-type unloading goods inside container platform, be put into assigned address, and closed the powdery material unloading door of freight container, open gate, container lateral end, pack into other article such as aluminium ingot, carry out the transportation of other goods with freight container, improved rail transportation efficiency, reduce traffic cost.
