High-efficiency production sintering machine

Abstract

The invention discloses a high-efficiency production sintering machine. The sintering machine can avoid the situation that a user manually takes down the blocky impurities, so that the labor is saved,and the practicability is improved, so that raw materials can be uniformly distribute; the sintering machine can avoid the situations that the raw materials of the platform edge of the sintering machine are small, and the intermediate raw materials are more; a turnover baffle is arranged above a round roller, so that the feeding speed and the feeding amount are conveniently adjusted. In addition,a plurality of rows of steam pipes are arranged on a trolley, the bottoms of the steam pipes vertically downwards extend out of a plurality of air injection branch pipes arranged in parallel, and theair injection branch pipes spray steam to the raw materials on the trolley, so that the raw materials are sintered sufficiently, nitrogen oxides in final products are reduced, and the quality of theproducts is improved. A flue gas purification device is additionally arranged beside the trolley, the high-temperature flue gas dissipates a large amount of heat into the water in a heating liner through a heat dissipation pipe, the flue gas after heat dissipation by the heat dissipation pipe is discharged from a flue gas outlet pipe at the top, the sintering machine has the advantages that the device can avoid the problem that a filter plate is blocked due to too much dust in the smoke dust, high-temperature heat of the flue gas is recycled, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a highly efficient sintering machine. Background technique [0002] In sintering production, sintering raw materials directly affect the output and quality of sintering ore, and the process requires that sintering raw materials must be uniform and flat. In the prior art, a round roller leveler or a scraper leveler is used to level the surface of the sintered material, and the raw material falls from the silo to the raw material system, and after passing through the raw material system, the sintering machine trolley is covered, and passed through the round roller leveler or The scraper leveling device levels the material layer. [0003] However, the existing sintering machine only uses a scraper to scrape off the excess mineral material to maintain a standard height. Due to uneven feeding, there may be less raw material at the edge of the sintering machine platform, and the ex...

[0003] However, the existing sintering machine only uses a scraper to scrape off the excess mineral material to maintain a standard height. Due to uneven feeding, there may be less raw material at the edge of the sintering machine platform, and the existing flat material device cannot The raw materials are filled in time, and at the same time, due to the fact that the raw materials may contain massive impurities, the massive impurities are stuck in front of the flattening roller or the flattening plate, resulting in scratches and shortage of raw materials after flattening. At this time, it is necessary to manually remove the It is not convenient for users to remove the massive impurities; and the sinter particles stuck in the gaps of the grate bars and the sintered ore stuck on the grate bars need to be vibrated to remove the impurities on the grate bars, and most of the grate ba
