In the sintering process, various powdery iron-containing raw materials, flux, fuel and return ores are uniformly mixed according to the proportion, are granulated and are tiled on a sintering machine trolley for air draft ignition sintering, and the material distribution thickness of the sintering mixture on the sintering machine trolley can reach 700-plus-material 1100 mm.
The material distribution of the sintering trolley is a necessary process before sintering ignition, and the material distribution quality directly influences the subsequent sintering airflow distribution, the development process and sintering consolidation strength of each sintering belt, the power consumption of main sintering extraction and the like, so that the key indexes of the finished product rate of the sintering ore, the sintering consumption, the material quality of the sintering ore and the like are influenced.
At present, the sintering trolley cloth in China is generally provided with an integral type material pressing roller and an integral type or sectional type material scraping device, but the devices cannot perform material pressing according to different air permeability requirements of a material surface and effectively eliminate the influence of 'edge effect' on two sides of the trolley, the compactness of the material surface cannot be accurately controlled and adjusted along with the height of the material surface, only the material pressing is performed in a passive or driven state, and meanwhile, the material pressing cannot be effectively combined with the air permeability for improving the material distribution state, so that the material pressing device is difficult to adapt to the requirements of a sintering process, the stability of parameters of the subsequent sintering process is influenced, and the further improvement of economic and technical indexes of sintering is restricted.
Through patent search, related sintering cloth methods are disclosed at present. Such as: chinese patent application No. CN205245795U discloses a material leveling device for a sintering pallet, which is composed of a plurality of middle material leveling plates and a plurality of side material leveling plates, wherein the left and right sides of the material surface central line are symmetrically arranged, the adjacent material leveling plates are staggered back and forth, the lower ends of the material leveling plates are kept at the same level, and the higher ends are fixed by hinges or hooks. The balance material leveling device has the defects that balance of the compaction degree of a leveling material can not be kept by timely adjusting the balance weight in real time in the production process, and meanwhile, the mixture bulges easily formed between adjacent leveling plates at the material surface of a sintering trolley due to incomplete compaction, so that the air permeability of the material in the width direction of the trolley is inconsistent, and further the subsequent surface ignition and sintering processes are influenced.
Patent CN208505022U discloses a device for improving the air permeability of the charge level of a sintering machine, which comprises two triangular supports arranged oppositely, wherein the top ends of the two triangular supports are hinged with one ends of bearing arms, the other ends of the two bearing arms are connected with the same roller bearing, a steel-structured roller is sleeved outside the roller bearing, and the outer surface of the steel-structured roller is provided with a plurality of rows of short teeth; the air permeability of the charge level of the sintering machine can be improved, the resistance of air passing through the charge level is reduced, particularly after the charge level of the trolley is ignited and crusted, the air permeability of the charge level can be effectively improved through the device, and the power consumption of a fan is reduced; the upper limit of ignition temperature control can be properly released in production, the quality of the sintered ore at the upper part of the material layer of the sintering machine is improved, the return rate of the sintered ore is reduced, and the proportion and consumption of the sintered solid fuel are reduced. It only improves the gas permeability for at the driven bleeder vent that forms of charge level after the sintering ignition, if front end cloth unevenness, then easily artificially causes the gas permeability of platform truck width direction inconsistent, directly influences the unbalance of sintering speed in follow-up width direction, easily leads to the reduction of inconsistent and sintering ore quality in sintering terminal position.

s12, during the fine adjustment, the suspension hydraulic devices (112) on the two sides synchronously act;
s13, setting and protecting the maximum allowable difference value of the detection values of the pressure measuring devices (111) at the two sides, and when the difference value exceeds the protection value, indicating that the sintering trolley cloth is seriously unbalanced in the width direction of the trolley, adjusting the uniformity of the round roller feeder (102) and the nine-roller distributor (103) in the width direction of the cloth;
s14, the cleaning device (108) and the cloth press roll (105) are consistent in length and are provided with flexible steel brushes for keeping the surface of the press roll from being stuck.
