【考案の詳細な説明】 （産業上の利用分野） 本考案は焼結機給鉱部の集塵装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a dust collector for a sintering machine ore feeding section.

たる焼結を終了させた後焼結鉱として排鉱させる。(Prior Art) As is well known, in a continuous downward suction sintering machine, pallets are connected in series to form an endless conveyor, and the raw material is supplied to the pallet at the ore feeding section and its surface layer is set in the ignition furnace. The raw material in the pallet is sintered from the upper layer to the lower layer while moving to the mine ore side through the heat-retaining furnace, and after the sintering of all layers is completed, it is discharged as sinter ore.

る。During the production of sinter, a large amount of dust is generated from the feed ore to the ore discharge, so it is necessary to collect and remove the dust in the dust-containing gas in each process. That is, the dust in the suctioned waste gas is collected by a dedicated dust collector, and the dust generated in the ore supply section and the discharge ore section is provided with a dust collector separately from the dedicated dust collector. Dust is being collected.

供給装置へ導いて焼結する方法が開示されている。(Problems to be solved by the invention) However, since the dust collector has high construction cost and operating cost, an inexpensive dust collecting method has been proposed. For example, Japanese Patent Publication Sho 51
No. 23246 discloses that after the sintering layer near the mine ore side where the sintering reaction is in progress is cooled by means such as water sprinkling, the dust-containing gas generated on the mine ore side is introduced and sucked into the surface layer of the sinter layer. Japanese Patent Laid-Open No. 51-52903 discloses a method of collecting hot air between a ore feeder and an ignition furnace of a sintering machine, and a cooling device of the sintering machine. A method is disclosed in which the dust-containing gas to be discharged is guided to a hot air supply device and sintered.

インペラーの摩耗が著しい等の問題があった。However, in the method disclosed in Japanese Examined Patent Publication No. 51-23246, the dust collected in the sintering completion layer is crushed after the discharge of the sinter, and is scattered again when air-cooled by the cooler. Most of the dust was merely circulated in the sintering process, and in the method disclosed in JP-A-51-52903, the dust in the gas was trapped in the sintering raw material layer and then ignited. Although dust re-scattering can be prevented, the equipment cost and operating cost are increased because the dust-containing gas is guided from the cooler installed downstream of the mine ore to the hot air supply device upstream of the sintering machine. There is a problem that the impeller of the blower is notably worn due to the bulkiness and dust in the gas.

利用される。(Means for Solving the Problems) The present invention is directed to a continuous downward suction sinter machine, in which a dust collecting hood provided at a dust generating location near the sinter machine ore and a downstream side of the ignition furnace. A dust collector for a sintering machine ore feeding section, characterized in that it is configured to introduce dust generated at the dust-generating location into the heat-retaining furnace by connecting it to a furnace with a duct (operation) Continuous downward In the suction sintering machine, the surface layer is ignited in the ignition furnace, and the sintering reaction is progressing from the surface layer to the lower layer by being sucked from below. The sintering bed exits the ignition furnace and advances in the heat retention furnace. From that point, cracks occur in the surface layer of the sintered bed. These cracks are caused by the compaction accompanying the progress of the sintering reaction, and sometimes become large cracks, so-called air leaks are generated from which air that does not contribute to the sintering reaction is sucked, which causes a crack in the production of sinter. Although it was a problem, in the device of the present invention, since the dust-containing gas is introduced from the dust collecting hood into the heat retaining furnace where the inside has a negative pressure by the downward suction and is sucked into the sintering bed, When a crack is generated in the surface layer of the sintering bed, a large amount of dust-containing gas is sucked into the crack, and as a result, dust is deposited on the cracked portion to prevent air leakage. Further, when the cracked portion reaches the sintering reaction layer, the sucked dust is sintered and the dust is effectively used.

結機の上流側に設けるので、この間に設けるダクトも短
くて済む等経済的である。Further, since the dust-collecting hood is provided in the sintering machine ore feeding section and the heat-retaining furnace is also provided on the upstream side of the sintering machine, the duct provided between them is short and economical.
