Description
Technical field
This utility model belongs to SINTERING PRODUCTION technical field, is related to super deep-bed sintering, and more particularly to a kind of raising is burnt
The stirring device of knot bed permeability.
Background technology
In sintering production process, sinter mixture is wired on chassis after igniting, by the convulsion of air exhauster, inside from surface
Portion sinters from top to bottom, is sintered to sintering machine bogie grates surface always from surface and just completes, and enough air are to maintain combustion
The essential condition of burning, the air capacity of suction from top to bottom directly affect vertical sintering speed, and then affect the operation speed of sintering machine
Degree, Sintering Operation Index and production efficiency.
After high-temperature ignition, charge level melts rapidly encrustation to sinter mixture, have impact on the sky of suction from top to bottom
Tolerance, air capacity reduce burning away for fuel in making compound and slow, and vertical sintering speed is slack-off to directly affect sintering
Process is carried out, and sintered surface igniting Flashmelt crust, is caused stress excessively to be concentrated, is easily produced case crushing phenomenon,
Make surface return mine to increase.Therefore, it is necessary in the case of surface sinter quality is not destroyed, process to the crust on surface, protect
Card air can be uniformly pumped through from charge level, vertical sintering speed in raising sintering process, and then the speed of service of quickening sintering machine,
Improve Sintering Operation Index and production efficiency.
Deep-bed sintering is an important widely used sintering technology, is sintered with sinter strength, reduction is improved
The advantages of burnup, but the application of deep-bed sintering technology is also faced with some difficult problems.With the thickening of sinter bed, by material
The gas-flow resistance increase of layer, sintering velocity slow down, this not only adds the power consumption of blower fan, and cause under productivity of sinter
Drop, especially to enterprise that fine iron breeze is main raw materials for sintering.During super deep-bed sintering, sinter bed " auto accumulation heat " phenomenon
Seriously, this is because combustion zone is gradually moved down, sinter bed bottom is due to heat transmission and the effect of itself fuel combustion, high temperature
The section persistent period is long, and crucible zone occurred in material layer lower part heat surplus, and this has a strong impact on the breathability of the bed of material.Technical staff is changing
Do a lot of work in terms of kind bed permeability, control suitable raw material alkalinity levels, moisture, strengthen mixture granulation,
Big granule is mixed in sintering feed, but still the needs of super thick bed of material SINTERING PRODUCTION cannot be met, limit the yield of sintering deposit
And quality.
To improve the technical-economic index of SINTERING PRODUCTION, including Yield and quality, energy consumption and equipment life etc., did a lot
Super thick (bed of material height more than 800 millimeters) bed of material sintering explore：But which still adopts and once lights a fire, and adopt high negative pressure, Wind Volume
Single flow convulsion operation, it is intended to which in this way improving thickness of feed layer, but actual last igniting often causes deep bed sintering
Surface melting, makes the space blocking between the bed of material material, whole materialbeds comminution increase, in order to maintain operation, it is necessary to improve blower fan
Negative pressure and air quantity, on the one hand its result cause distinguished and admirable partial short-circuit, the whole bed of material not to reach Even Sintering, on the other hand again
Cause increasing considerably for energy consumption, not up to expected purpose, do not make progress always so far, technical staff is to super thick material
The exploration in layer sintering direction achieves no breakthrough.
The content of the invention
The purpose of this utility model is to provide a kind of stirring device for improving permeability of sintering material bed, increases sintered compound
The breathability of material, improves Sintering Yield, reduces sintering solid burnup.
A kind of stirring device for improving permeability of sintering material bed, it is characterised in that：Including loose metal roller, loose metal tooth, rotary shaft,
Drive system, jacking system and support platform；Loose metal roller is provided with 2～6 row's loose metal teeth, and loose metal roller is solid with bearing by rotary shaft
Fixed set connection, bearing fixing sleeve are connected with rotary drive system；Loose metal roll end bearing fixing sleeve is provided with induction apparatuss, lifting system
System is connected with bearing fixing sleeve；Jacking system top is provided with lift drive system, and lift drive system and jacking system are fixed on
In support platform.
Described loose metal tooth is cone-shaped, sickleshaped.
Loose metal roll spacing is adjusted according to sintering material layer thickness from charge level height；Its rotating speed is adjusted to 4～10 according to machine speed
Turn/min.
Before loose metal roller is arranged on secondary material distributing device, the distance with secondary material distributing device is 0.5～2m.
Following beneficial effect can be obtained by this utility model：
1st, improve the initially ventilative situation of sinter mixture, reduce the power consumption of blower fan, increase the logical of the sintering position
Air quantity, is conducive to controlling sinter mixture that cloth twice adds while reaching sintering end point, improves sinter quality.
2nd, optimize distribution of the fuel in sinter mixture, improve Sintering Yield, reduce sintering solid burnup.
