Description
Technical field
The present invention relates to petroleum refining industry Delayed Coking Technology field, specifically petroleum coke particles and aqueous mixtures
Feeding mechanism in sealing conveying.
Background technology
Delayed coking is a kind of Petroleum Processing Technology, and using mink cell focus as raw material, pyrogenetic reaction is carried out in coke drum, generation
Coke close-burning in tower.The upper and lower cover of coke drum is opened, coke is smashed using hydraulic decoking method and discharged from Xia Takou,
Coke drum upper and lower cover is closed, enters back into next step production cycle.
The coke and water discharged at present are flowed into burnt pond and are dehydrated, and are carried out batch turning to the coke in pond by grab bucket crane, are grabbed
Go out, into next procedure processing or directly entrucking outward transport.The outdoor open setting in burnt pond, it is burnt in batch turning and catching transport process
The dust and the peculiar smell of volatile matter that charcoal scatters, kicks up pollute to surrounding enviroment.The pollution sources to be eliminated, it is necessary to what is opened wide
Operating condition closed processes.Need to set the feeding mechanism formed a connecting link between surge bunker and defeated burnt equipment during closed, make
Whole system energy reliably working.
Utility model content
The present invention provides a kind of petroleum coke feeding mechanism, solution be it is defeated it is burnt during when upstream supplied materials increases suddenly,
In the case that material position is very high in surge bunker, also can be relatively uniform give fed downstream, be unlikely to upstream device overload operation
Go wrong.
To realize above-mentioned technical purpose, used technical scheme is：A kind of petroleum coke feeding mechanism, provided with hopper, material
Struggle against as long tubular shell, cylindrical cavity is provided with hopper, be horizontally disposed with screw feeding axle in hopper, the one of screw feeding axle
End is arranged on the side of hopper by bearing supporting, and is connected after stretching out hopper with drive mechanism, the other end of screw feeding axle
Without the hanging setting of support, discharging opening, discharging opening are offered on the side of hopper corresponding to the empty one end set of screw feeding axle suspension
It is coaxially disposed with screw feeding axle, the charging isometric with screw feeding axle is offered on the hopper headwall above screw feeding axle
Mouthful.
Drive mechanism described in the utility model includes hydraulic motor and shaft coupling, and hydraulic motor passes through shaft coupling and spiral
Feeding axis connection.
Bearing described in the utility model is made up of the bearing A and bearing B set with end.
Bearing A described in the utility model is sliding bearing.
The utility model beneficial effect is：
1st, screw feeding axle and hopper discharging opening are coaxial, convey material and do not change traffic direction, feeding resistance reduces, carried
The volumetric efficiency of the high defeated burnt equipment in downstream.
2nd, screw feeding axle uses cantilever support mode, cancels the hanging supporting of discharge port end, further reduces feeding resistance
Power, improve the volumetric efficiency of the defeated burnt equipment in downstream.
3rd, bearing A and bearing B is arranged on the outside of hopper and is easy to check, overhauls, change.
4th, fluid motor-driven, it is easy to rotating, regulation rotating speed, realizes that the automation of feeding capacity is adjusted, energy antiport,
The material arranged to remove downstream fault equipment to fall, provided conveniently to repair faulty equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 left view；
In figure：1st, hopper, 2, screw feeding axle, 3, bearing A, 4, bearing block, 5, bearing B, 6, shaft coupling, 7, driving machine
Structure, 8, discharging opening, 9, charging aperture.
Embodiment
As shown in figure 1, a kind of petroleum coke feeding mechanism, is arranged between surge bunker and defeated burnt equipment, provided with hopper 1, material
Bucket 1 is long tubular shell, and cylindrical cavity is provided with hopper 1, and screw feeding axle 2, screw feeding axle are horizontally disposed with hopper 1
By power transmission shaft and the helical blade set along drive shaft axis（Packing auger blade）Composition, one end of screw feeding axle 2 passes through axle
Hold supporting and be arranged on the side of hopper 1, and be connected after stretching out hopper 1 with drive mechanism 7, the other end of screw feeding axle 2 is without branch
Support is hanging to be set, and offers discharging opening 8, discharging opening 8 corresponding to one end that screw feeding axle 2 is vacantly set on the side of hopper 1
It is coaxially disposed, is offered on the headwall of hopper 1 above screw feeding axle 2 isometric with screw feeding axle 2 with screw feeding axle 2
Charging aperture 9, charging aperture 9 is completely corresponding consistent with the discharging opening of surge bunker, and the discharging of surge bunker is directly entered feeding mechanism.
Described drive mechanism 7 includes hydraulic motor and shaft coupling 6, and hydraulic motor passes through shaft coupling 6 and screw feeding axle 2
Connection, hydraulic motor and shaft coupling 6 are arranged at outside feed bin.
Described bearing is made up of the bearing A3 and bearing B5 set with end, can be fixedly connected by bearing block 4 with feed bin,
Bearing A3 and bearing B5 are set respectively in the both sides of bearing block 4, there is certain distance between two bearings, cantilever branch is realized with this
Support.
Described bearing A3 is sliding bearing.
Material is pushed ahead under the thrust of screw feeding axle, when entering material bin discharging opening, is had disengaged from spiral and is sent
Expect axle, rely primarily on the extruding of material and storeroom and waterpower is promoted and advanced.If screw feeding axle is different from hopper discharging opening
Axle is set, and material traffic direction necessarily changes, and increases the frictional force of material and duct wall, reduces the flow velocity of material, reduces unit
Feeding capacity in time, reduce the volumetric efficiency of the defeated burnt equipment in downstream.
Usual screw feeding axle two supports；As hopper discharge port end uses underslung bearing, conveying section can be reduced, formed
Bottleneck, increase transporting resistance, reduce the throughput in the material unit interval, reduce the volumetric efficiency of the defeated burnt equipment in downstream.Therefore
One end of screw feeding axle is hanging, improve the space size of discharging opening, increase the throughput in the material unit interval, Bu Hui
Feeding capacity forms bottleneck when increasing.
The workflow and principle of petroleum coke feeding mechanism of the present invention be：Rotated by fluid motor-driven screw feeding axle,
Coke in surge bunker and the mixture of water are transported to upstream device by default feeding capacity；By adjusting hydraulic motor rotary speed
Feeding capacity can be changed；Energy antiport, the material arranged to remove downstream fault equipment to fall.
It is described above, only it is the preferred embodiment of invention, any formal limitation not is made to the present invention, although
The present invention is disclosed above with preferred embodiment, but is not limited to invent, any person skilled in the art,
Do not depart from the range of technical solution of the present invention, when the technology contents using the disclosure above make a little change or are modified to equivalent
The equivalent embodiment of change, as long as being without departing from technical solution of the present invention content, the technical spirit according to invention is implemented to more than
Any simple modification, equivalent change and modification for being made of example, in the range of still falling within technical solution of the present invention.
