Technical Field
[0001] This utility model relates to the field of stable support technology for conical arches of hot blast stoves, and in particular to a stable support device for conical arches of hot blast stoves. Background Technology
[0002] Hot air furnaces are thermal power machinery that began to be widely used in my country in the late 1970s. They have become a replacement product for electric heat sources and traditional steam power heat sources in many industries. Hot air furnaces come in many varieties and series, and are classified into two types according to the method of coal feeding: hand-fired and machine-fired, and according to the type of fuel: coal, oil, gas, etc.
[0003] The conical dome of a hot blast stove refers to the conical dome structure in a hot blast stove. This structure is usually used to connect the combustion chamber and the regenerator. The design of the conical dome helps to reduce stress concentration and improve the service life and stability of the hot blast stove. The conical dome of a hot blast stove is usually built with high-quality, high-expansion silica refractory bricks to form a special combustion chamber structure. This structure is confined within a conical furnace shell that is smaller at the top and larger at the bottom. When the hot blast stove is being baked and heated, the refractory material will expand, thus forming a complex stress concentration phenomenon.
[0004] The conical dome of the hot blast stove is installed through a support structure on the wall. However, the traditional support structure lacks an automatic leveling mechanism. Since the conical dome of the hot blast stove is relatively heavy, if it tilts, it will affect the stability of the support structure, and in severe cases, it may cause the conical dome of the hot blast stove to fall down.
[0005] Therefore, it is necessary to provide a stable support device for the conical dome of the hot blast stove to solve the above-mentioned technical problems. Utility Model Content
