Background technique
Sintering process extremely burns tiling after the iron-bearing material of various powderies, flux, fuel, return mine mixing, pelletizing according to the ratio
Carry out ignition sintering on knot machine trolley 7, sintering feed on sintering pallet 7 fabric thickness up to 700-1000mm.
Sintering machine charge level is lighted a fire after furnace igniting, and under the action of suction pressure, sintering process carries out from top to bottom, sintering
The exhaust gas temperature that process generates is transmitted from top to bottom, and the bed of material is there are auto accumulation heat effect, and the bed of material more down, get over by the temperature of combustion zone
Height, therefore the sintering machine bed of material is there are top shortage of heat, lower part heat surplus, the case where even resulting in superfusion.In sintering feed
In the process, it takes shuttle type distributing device-multi-roller spreader and carries out joint cloth, it is therefore an objective to by bulky grain, carbon containing few mixture
For cloth in 7 lower part of trolley, little particle, carbon containing high mixture are wired to 7 top of trolley, but still can not thoroughly solve sintering machine material at present
Layer the case where temperature distribution is non-uniform for top and the bottom.
The case where to solve bed of material top shortage of heat, further promotes bed of material top sinter quality, reduces sinter
The rate of return mine, it is main by controlling reasonable sintering ignition temperature, on the one hand charge level sintering temperature is controlled, still further aspect is maximum
Degree supplements bed of material top heat, but higher firing temperature is easy to cause charge level crust, gas permeability to be deteriorated, and influences sintering supervisor
Pressure rise further influences sintering machine production efficiency.
Utility model content
The utility model aim is to provide a kind of device for improving sintering machine charge level gas permeability, is able to ascend sintering machine material
Face gas permeability proposes sintering efficiency.
The technical solution adopted in the utility model is a kind of device for improving sintering machine charge level gas permeability, including two phases
To the A-frame of setting, two A-frame tops are hinged with roll bearing arm one end, and two roll bearing arm other end connections are same
Roller bearings, roller bearings are socketed with steel structure roller outside, and steel structure outer surface of cylinder is provided with multiple rows of short tooth.
The utility model is also characterized by:
It is provided with limiting device on one side close to steel structure roller on each A-frame, limiting device is apart from A-frame
The length of upper end is less than bearing arm lengths.
Each limiting device is a supporter, and supporter is fixed on A-frame.
Two A-frames are fixed on ground.
Short tooth can penetrate sintering machine charge level.
The beneficial effects of the utility model are:
A kind of device for improving sintering machine charge level gas permeability of the utility model, is able to ascend the gas permeability of sintering machine charge level,
Resistance of the air by charge level is reduced, especially after 7 charge level of trolley crust, charge level gas permeability can be effectively improved by the device,
Reduce blower power consumption；Firing temperature upper control limit can be suitably decontroled in production, improve sintering machine bed of material top sinter quality,
Small sintering ore rate is reduced, while advantageously reducing sintering solid fuel mixing rate and consumption.
Detailed description of the invention
Fig. 1 is a kind of apparatus structure schematic diagram for improving sintering machine charge level gas permeability of the utility model.
In figure, 1. steel structure rollers, 2. roller bearings, 3. short teeth, 4. roll bearing arms, 5. limiting devices, 6. A-frames, 7.
Vehicle.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of device for improving sintering machine charge level gas permeability of the utility model, is oppositely arranged as shown in Figure 1, including two
A-frame 6, two 6 tops of A-frame are hinged with 4 one end of roll bearing arm, and two 4 other ends of roll bearing arm connect same roller
Bearing 2, roller bearings 2 are socketed with steel structure roller 1 outside, and steel structure roller 1 can be rotated around roller bearings 2,1 appearance of steel structure roller
Face is provided with multiple rows of short tooth 3.
It is provided with limiting device 5 on one side close to steel structure roller 1 on each A-frame 6, limiting device 5 is apart from triangle
The length of 6 upper end of bracket is less than 4 length of roll bearing arm.
Each limiting device 5 is a supporter, and supporter is fixed on A-frame 6, is used to support roll bearing arm 4.
Two A-frames 6 are fixed on ground.
Short tooth 3 can penetrate sintering machine charge level, form air duct on sintering machine charge level, make on sintering machine charge level in burning
It is lower uniform.
Short tooth 3 can be selected as 6-8 and arrange sharp sawtooth, every row interval 150-200mm.
A kind of device course of work for improving sintering machine charge level gas permeability of the utility model is as follows:
In use, being sling steel structure roller 1 by crane, then the trolley 7 that upper bottom surface is sintering machine charge level is moved to
Between two A-frames 6, steel structure roller 1 is placed on sintering machine charge level by crane, mobile trolley used 7, steel structure roller 1 exists
It is rolled on sintering machine charge level, multiple rows of short tooth 3 penetrates sintering machine charge level, forms air duct on sintering machine charge level, makes in 7 transverse direction of trolley
The uniformity of air quantity improves sintering machine and is sintered efficiency；It is aobvious using gas permeability effect is improved after the device if sintering machine charge level crusts
It writes.
After use, steel structure roller 1 is sling by crane, roll bearing arm 4 is placed on limiting device 5.
By the above-mentioned means, a kind of device for improving sintering machine charge level gas permeability of the utility model, is able to ascend sintering machine
The gas permeability of charge level reduces resistance of the air by charge level, especially after 7 charge level of trolley crust, can effectively be changed by the device
Kind charge level gas permeability, reduces blower power consumption；Firing temperature upper control limit can be suitably decontroled in production, improved on the sintering machine bed of material
Portion's sinter quality reduces small sintering ore rate, while advantageously reducing sintering solid fuel mixing rate and consumption.
