    [28] In addition, a sealing member 14 is attached between the sintering machine trolley 1 and the upper air blower tube 10 to allow air to flow from the bottom to the top without leaking out.
    [29] Hereinafter, the operation of the present invention will be described in detail.
    [30] As shown in Fig. 3 and Fig. 4, in the sintering machine trolley (1) is charged a mixture of various spectroscopy to produce a sintered ore, subsidiary materials such as limestone, silica sand, serpentine and anthracite as a heat source.
    [31] The compounding material charged in the sintering machine cart 1 is horizontally moved and the upper part is ignited by the ignition furnace 2, and the compounding material is # 25 in front of the lower blower tube 3 having the lower side damper 12a. It is fired while being transferred to the burn-in lower blower pipe (3).
    [32] At this time, the calcination completed layer 7c is thickened by melt bonding gradually from the upper portion, and the portion where the calcination is completed is cooled while cold air is introduced from the upper portion.
    [33] The air sucked as described above is detected by a thermometer in the lower blower tube 3 and displayed on the monitor to the operator of the cab, and the operator controls the sintering speed with reference to this data.
    [34] As shown in FIG. 6, as the sintering proceeds in a general sintering process, the temperature graph 17 gradually increases as the light is moved to the light distribution unit, and after a certain period, the temperature passes the highest point and the temperature graph decreases thereafter. Keep 17.
    [35] At this time, the highest point of the temperature is referred to as BURN THROUGH POINT (15) up to the point 12 m in front of the last upper air blower tube (10) located at the far right end of the sintering machine bogie (1), and the air passing through the pipe at this point Temperature reaches its peak.
    [36] If the temperature of the lower blower tube 3, which is # 24 in the previous stage of the lower blower tube 3 including the lower side damper 12a, is higher than 430 ° C, the lower part installed inside the lower blower tube 3 of # 26 The damper 12b is closed and air is introduced while the lower side damper 12a is opened.
    [37] When the air flows in, the upper side damper 13a is closed and the upper damper 13b is opened to move the air from the bottom to the top.
    [38] On the other hand, if the internal temperature of the lower blower tube 3 of # 24 is 430 ° C. or less, the opposite phenomenon occurs and the air flows from the top to the bottom.
    [39] Further, as described above, the temperature value detection of the lower blower pipe 3, which is # 24, which determines the suction direction of the air, serves to calculate every minute.
    [40] As described above, from the upper blower tube 10 arranged next to the upper blower tube 10 including the upper side damper 13a, air is introduced from the lower portion to the upper portion, and sulfur oxides and nitrogen oxides, which are pollutants, are almost Uncontained clean air is exhausted.
    [41] As described above, the upper and lower two-way air suction device for high production operation according to the present invention can check the firing state of the sintered ore by using the two-way suction method according to the situation, it is possible to produce a stable quality of sintered ore during high production operation By maximizing the cooling efficiency of the sintered ore, there is a very good effect of reducing the total emissions of sulfur oxides and nitrogen oxides in the sinter truck.
