Embodiment Construction
[0032] The first embodiment: as figure 1 , 2 As shown, the main body of this anti-leakage sintering machine has a trolley 1, a smoke exhaust wind box 4, and a suction box 7 is arranged on the outside of the box plate 2 of the trolley 1, combined with Figure 5 The air suction port 6 of the air suction box 7 faces the outside of the compartment plate 2 of the trolley 1, the air suction box 7 has an air duct 8 connected to the fan 9, and the exhaust end of the fan 9 has an air supply pipe 10, and the air outlet of the air supply pipe 10 11 On the outer side of the upper part of the suction box 7, the air outlet 11 faces the compartment panel 2. During work, negative pressure airflow is formed on the outside of the vertical box 2 under the action of the fan 9, so that the negative pressure outside the box 2 is equal or similar to the negative pressure inside the box 2. The exhaust end of the fan 9 has an air supply pipe 10 The air exhaust port 11 of the air supply pipe 10 is on...

The invention relates to an air leakage preventing sintering machine. The air leakage preventing sintering machine comprises a trolley (1), a smoke exhaust bellow (4) and a handpiece (5) and is characterized in that an air suction box (7) is arranged outside the trolley (1) in a sintering section, and an air suction opening (6) of the air suction box (7) faces the trolley (1); the other end of theair suction box (7) is connected with the fan (9), and an air conveying pipe (10) is arranged at the air conveying end of the fan (9); and the air conveying pipe (10) is provided with an exhaust opening (11), and the exhaust opening (11) is formed in the edge of the outer side of the air suction opening (6). The air leakage preventing sintering machine has the beneficial effects that a circulating air net is arranged on the outer side of the sintering trolley, the outer air net can generate airflow with pressure equal or close to the pressure in the trolley and in the direction opposite to that of airflow in the trolley, gas outside the trolley cannot enter the trolley easily, air leakage can be effectively inhibited, the smoke exhaust rate of the smoke exhaust bellow is reduced, the oxygen content of exhausted smoke is reduced, and the air leakage preventing sintering machine is good equipment for governing smoke pollution from the source.
Description
technical field [0001] The invention relates to an environmental protection equipment, that is, a leak-proof sintering machine Background technique [0002] Before steelmaking, the ore powder is generally sintered. During sintering, the ore powder must be installed in the trolley and enter the sintering kiln. gas out. However, there are joints on the side of the trolley and the compartment board; there are also joints between the bottom plate of the trolley box and the vacuum bellows. When working, under the action of the vacuum bellows at the bottom of the trolley, there is a negative pressure airflow in the trolley. Under the action of the negative pressure airflow on the side panels and bottom plates of the trolley, outside air flows into the vacuum bellows from the gaps, and the air flowing in from the gaps does not participate in sintering. . The air that has not participated in sintering not only has high oxygen content, but also produces harmful oxides after being ...
