Description
Technical field
The invention belongs to metallurgy industry sintering technology field more particularly to a kind of sintering silo sizing cleaning plant and sides
Method.
Background technique
As shown in Figure 1, sintering machine distributing device includes shuttle type distributing device 100, feed bin 200, round roller or wide belt feeder
300 and the nine roller feeder 400.
Sintering machine distributing requires the bidirectional reciprocating in 200 width direction of feed bin of shuttle type distributing device 100 to run, and sintering feed is equal
It is even to be distributed in feed bin 200.It is required that and sintering feed cloth even density smooth along trolley width direction charge level, high along the trolley bed of material
The segregation distribution effect that direction sintering feed is in upper layer fine size and lower layer's coarse size is spent, bed permeability is improved, realizes deep bed sintering
Sintering improves Sintering Operation Index.
200 shape of sintering silo is top cuboid lower part rectangular pyramid, and highly 6~7 meters, sintering feed is Iron Ore Powder, melts
The mixture of the materials such as agent, solid fuel, moisture is up to 7~8%, especially low silicon high alkalinity and the raw materials for sintering knot for improving fine powder rate
Structure, quick lime proportion is big, and sintering feed stickiness is big, and sintering feed downstream rate is slow, and dead time is up to 15min or more, it is easy to make
At feed bin sizing.
Feed bin sizing makes in storehouse material position 201 low on one side on one side high, sees Fig. 1, and sintering feed is in the case where self weight segregation acts on, A
It holds large granular materials in the majority, causes feed bin discharge pressure and load unbalanced, it is thick that corresponding sintering machine width direction generates the bed of material
Spend different, ignition results are different, and sintering machine A end edge portion effect is seriously and vertical sintering speed is fast, early arrive at sintering end point, behaviour
It is consistent to be difficult to console vehicle-width direction sintering velocity, influences sintering process air quantity and heat is unevenly distributed, is sintered mineral
It is poor to measure.
When feed bin sizing is serious, material is seriously lacked within the scope of corresponding sintering machine A end 300mm, increases and shuts down clear material number, reduce
It is sintered production capacity.
Currently, cleaning feed bin sizing mainly has following four method in the prior art:
One, hopper wall vibrator is installed in feed bin lower part two sides outer wall, when feed bin sizing is serious, controls low material position operation
(it is unstable that low material position influences discharge quantity), starts hopper wall vibrator rapping.This mode handles that sizing is extremely limited, and effect is unknown
It is aobvious.When sizing amount is less, starting hopper wall vibrator sizing can be fallen, and when sizing is serious, rapping is not got off, and continuous shaking is anti-
And sizing can be made more tighter more secured, opposite effect is played in vibration.
Two, air bubble is installed in feed bin lower part two sides outer wall, (low material position influences discharge quantity not to the low material position operation of control feed bin
Stablize), periodically start air bubble rapping.Air bubble corresponding position does not have sizing, but the sizing of surrounding gradually increases, and sizing obtains
It is certain to alleviate, but effect is limited, and only the opposite extension of sizing period, still needs to often shut down artificial treatment sizing.
Three, sonic wave vibrator is installed in two sides inside feed bin, and Open Side Down for vibrator, and vibration is primary at regular intervals.
Feed bin expect clearly after a period of time in, bin bottom sizing is reduced, and top sizing is more.With the extension of time, top
Sizing gradually increases, bottom sizing mutually strain it is more, it is clear to expect that the period is extended, but sizing phenomenon still remains.
Four, liner plate is expected clearly in side-by-side mounting inside feed bin, and the low material position operation of control feed bin is periodically beaten liner plate and removed and glues
Material.This cleaning sizing method using effect is undesirable, and the sizing hung on liner plate is very more, and sizing is difficult under rapping
It goes.
To sum up, there are following defect and deficiencies for existing cleaning feed bin sizing method: 1) only part installation is clear expects facility, does not have
There is gross area to act on sizing；2) when material erection of equipment is outside bulkhead clearly, without directly acting on sizing during clear material；When clear material
For facility static suspension in feed bin inner wall, material impacting expects clearly facility when unclear material, clear to expect that facility itself has sticked material, very
Hardly possible carries out clear material operation；3) material facility clearly is minimum to the destructive power of sizing, keeps sizing more and more closely knit serious, it is difficult to clear up.
Therefore, in metallurgy industry sintering technology field, the cleaning of sintering silo sizing there are still research and is improved
Demand, this is also a research hotspot and emphasis in current metallurgy industry sintering technology field, and the even more present invention has been able to
At starting point.
