Uniform and stable structure is a crucial quality requirement, to produce the big specification ultra high power graphite electrode of Φ 600mm or more, it is necessary to
There is 3500 tons or more of large size is vertical to smash sleeping extruder, the vertical feeding device for smashing sleeping extruder configuration of domestic large size is generally solid
Determine chute type, because height-limited between vacuum (-tight) housing and material cylinder, fixed chute can just reach material cylinder edge；Such fixed chute,
Thickener, with biggish action potential, is flushed in press material cylinder from eminence, and thickener is in material cylinder, and the formation high side in side is low, bulk
Thickener is distributed at a side material cylinder wall, when vacuumizing, because thin, the vacuum degree of thickener when causing to vacuumize is expected in the side side Liao Hou
Inhomogenous, because thickener thickness and size distribution are uneven when tamping, density is not easy the green compact solution uniformly squeezed out after thickener tamping
After cuing open, discovery size distribution is uneven, and the compactness of green compact is also inhomogenous, is also easy to produce crackle when roasting is heat-treated with graphitization,
Make scrap of the product, in use, easily selective oxidation occur too fast on electric furnace, concave-convex or necking, root occurs in electrode surface
Source is that green structure is unevenly caused, and leading to the non-uniform core of green structure is that thickener non-uniform charging causes.To improve
The uniformity of the big specification ultra high power green electrode structure of Φ 600mm or more, our company, which opposes, smashes the loading method of sleeping extruder
Crowded deep study and analysis has been carried out, innovative design has been carried out to the classical charging device of 3500 tons of press, paste when solving charging
Expect the uniformity of distribution, ensures that the uniformity of the big specification ultra-high power graphite electrode green structure of Φ 600mm or more, product quality obtain
The promotion of essence is arrived.

Thickener feeding is put in moving horizontally on conveyor belt trolley at press material cylinder center by belt conveyor, moves horizontally conveying skin
Band trolley rotating forward can send thickener to material cylinder center into press, and thickener is evenly distributed in material cylinder circumference, moves horizontally conveying
Remaining bulk cargo cold burden can be sent into hopper by belt trolley in initial position reversion.
In order to achieve the object of the present invention the technical solution adopted is that:
One kind is vertical to smash the novel feeding device of sleeping extruder, and cooler pot door aperture is controlled, defeated according to moving horizontally
The material transfer speed and material transfer amount for sending belt trolley, control the aperture of cooler pot door, keep the incoming press material cylinder speed of thickener controllable,
Ensure the uniformity that thickener is distributed in material cylinder；
It moves horizontally conveyor belt trolley to be set as to reach in press material cylinder, thickener is made just to fall into material cylinder center, protect
The uniformity that barrier thickener is distributed in material cylinder；
Fixed belt conveyor is combined with moving horizontally conveyor belt trolley, thickener transmission potential energy is reduced, impacts
Power reduces, and is uniformly distributed in material cylinder conducive to thickener；
Moving horizontally conveyor belt trolley can be transmitted with positive and negative rotation, and forward direction, reversely will fixed skin to feeding in press material cylinder
It with conveyer and moves horizontally in the extra bulk cargo of conveyor belt trolley and cold burden feeding hopper, preventing cold burden from entering influences in product
Portion's structure, while being conducive to remaining bulk cargo and cold burden collection improvement operating environment.
The beneficial effects of the present invention are:
1, apparatus of the present invention have ensured the uniformity of thickener distribution, guarantee the big specification ultra high power electricity of Φ 600mm or more
The uniformity of pole green structure, dissection green structure observation, particle size distribution is good, and particle oriented is good, different portions
The density uniformity of position is ideal, and density contrast is lower than 0.005g/cm in different parts circumference3,；And traditional fixed chute formula charging
Density contrast has reached 0.021g/cm in different parts circumference3。
2, apparatus of the present invention are super using this vertical Φ 600mm for smashing the novel feeding device compacting of sleeping extruder or more big specification
Without waste product in the roasting and graphitization heat treatment of high power electrodes, and traditional fixed chute formula charging green compact are in roasting and graphite
Change rejection rate in heat treatment and reaches 2.68% or more.
3, the present invention is reached using the vertical quality for smashing sleeping extruder production Φ 600mm or more big specification ultra-high power graphite electrode
The effect of stable homogeneous.
4, the present invention is vertical smashes that the novel feeding device of sleeping extruder is stable, and high-efficient, failure rate is extremely low, easy to maintenance,
It is practical, moreover it is possible to bring good economic benefits.
