Description

Technical Field

[0001] The utility model relates to the field of heating furnaces, in particular to a novel intelligent combustion device for heating furnaces. Background Art

[0002] Heating furnace is a common industrial equipment, mainly used for heat treatment or heating of various materials. There are many types, including but not limited to continuous heating furnace, tubular heating furnace and regenerative heating furnace.

[0003] After searching, the application number is "202223584935.8", which provides an environmentally friendly ultra-low ammonia combustion device for a heating furnace. After the machine body starts to burn, high-temperature flue gas is generated inside the combustion chamber. The high-temperature flue gas flows into the smoke pipe from the top of the combustion chamber and enters the lower casing along the pipeline. When the air inside the combustion chamber decreases and the oxygen is insufficient, the combustion medium inside the combustion chamber is not fully burned, and a large amount of flue gas is generated. A large amount of flue gas enters the smoke pipe, and the pressure inside the smoke pipe increases. The flue gas pressure pushes the slider to move forward, and the slider drives the plug to move forward. The spring is compressed and deformed, and the plug drives pull ring one to move forward. Pull ring one pulls pull ring two through the pull rope. At this time, the movable door opens, and external cold air enters the inner tube. Since the inner tube is inside the casing, the inside of the casing is full of high-temperature flue gas, so the cold air will be heated after entering the inner tube to prevent the air from being too cold and entering the combustion chamber, causing the temperature inside the combustion chamber to drop sharply, affecting work.

[0004] The above-mentioned method heats the inner side of the air inlet pipe through flue gas, thereby heating the incoming cold air and reducing the influence of the cold airflow on combustion. However, when this structure is in use, when the external ambient temperature is low, the heat loss of the connecting channel for conveying flue gas to the air inlet pipe increases, which reduces the heating effect of the cold airflow and makes the temperature of the incoming cold airflow low, affecting the heating effect of the heating furnace.

When in use, when the heating furnace main body 1 is heated, the generated smoke is discharged through the smoke outlet pipe 2, and the smoke flows into the connecting pipe 8. The air pressure of the smoke drives the movable plate 9 to move, and the movable plate 9 drives the fixed rod 10 to move. The fixed rod 10 mobilizes the movable block 12 to move. Under the action of the connecting rope, the movable door 6 on the lower side is opened, so that the external airflow can enter the heating furnace main body 1 through the air inlet pipe 5, so as to facilitate the introduction of oxygen for full combustion.
