Description
Technical Field
The utility model relates to a large-scale gyration barrel discharge end abrasionproof decreases structure mainly uses at sintering machine granulator barrel system, is favorable to improving granulator barrel life.
Background
The sintering process comprises the following steps: the sintering raw materials such as powder ore, flux, coke powder, return fines and the like stored in the batching ore tank are weighed and quantitatively output by a batching adhesive tape according to a certain proportion. The raw materials output according to the proportion are conveyed to a cylinder mixer by a belt conveyor to carry out material mixing and water wetting operation, and the materials after primary mixing are conveyed to a cylinder granulator by the belt conveyor to carry out material granulation operation. The mixture after granulation is distributed evenly on a sintering machine trolley with a bottom material by a belt conveyor and a sintering swing belt conveyor. The trolley with the mixed materials distributed well moves on the track, fuel in the surface material layer is ignited through the ignition furnace, and the mixed materials on the trolley are subjected to physical and chemical sintering reaction from top to bottom under the action of air draft. When the sintering machine trolley runs to the tail of the machine, the sintering process is finished, and the sintered cake on the trolley is crushed by the single-roller crusher and enters the blast ring type cooler for forced cooling. And (4) screening finished product whole granules of the cooled sinter, and dividing the cooled sinter into finished product ore, bedding material and return fines according to the grade. And conveying the finished ore to a blast furnace, and conveying the bedding materials and the return ores to a bedding material groove and a return ore groove respectively. Meanwhile, waste gas generated in the sintering process is sucked to the main exhaust pipe through the lower air box by the main exhaust fan, is dedusted when passing through the deduster, and is discharged from a chimney.
Mixing and granulating sintering materials: 1. to summarize: the main purposes of mixing and granulating the sintering material are to uniformly distribute all components of the material, so as to be beneficial to the sintering process and ensure the uniformity and stability of the components of the sintering ore. When the materials are stirred and mixed, the materials are wetted and granulated by adding water, and the material structure is improved, so that the air permeability of a sinter layer in the sintering process is increased. In order to ensure the temperature of the materials, steam injection pipes are arranged in a mixer and a granulator; and the mixer adds hot water, and the granulator lets in high temperature hot waste gas to raise the mixture temperature. 2. Primary mixing and granulating: in the first mixing process, sludge (steelmaking sludge) is mainly added besides clear water, the moisture of the mixed material is generally controlled to be 7.5% -8.5%, an infrared moisture monitor is arranged, the adding amount of the sludge is a constant in principle, and the moisture of the material is stabilized through adjustment of a clear water pipe valve. It is noted that the moisture stability of the material is related to the stability of the dosage. 3. And (3) secondary mixing and granulating: the main function is to carry out enhanced granulation on the materials after being wetted and uniformly mixed. The mechanical force generated by the rotation of the cylinder and the adhesion of the wetting material form 3.0 mm-8.0 mm size fraction pellets to improve the granularity structure of the sintering material and the air permeability of the material layer in the sintering process, and finally the purposes of increasing production and reducing consumption are achieved. Therefore, a certain amount of water needs to be supplemented in the granulation process to meet the requirement of sintering production. After passing through the granulator, the moisture of the material is usually 8.0-9.0%, the longer the stable retention time of the moisture of the material is, the better the granularity of the material is larger than 3.0mm, and the better the size fraction is.
Under the effect of materials bonded on the chute, the cylinder of the granulator in the original design is severely worn after being operated for a period of time, the cylinder is worn through within one month, the blanking is very serious, and the granulator needs to be stopped for processing if the granulator does not stay in a fixed repair period.
