Technical Field
The utility model relates to a large sealed furnace door of an industrial smelting furnace, in particular to a sealed furnace door of a smelting furnace used in steel plants and smelting plants.
Background
Industrial smelting furnaces are common devices in the smelting industry, and during use, the main heat dissipation position of the industrial smelting furnace is in the furnace door part. At present, the sealing parts on the furnace door of the industrial smelting furnace are all made of iron castings and asbestos packing, and the sealing parts have the following defects: firstly, because cast iron can not be welded, the cast iron sealing element and the furnace door frame component can only be connected by bolts, and the cast iron sealing element and the furnace door frame component are easy to misplace when being used for a long time in a high-temperature environment, so that the sealing performance is influenced; meanwhile, the asbestos packing is used for sealing, the sealing area is too small, the sealing is not strict enough, the replacement is inconvenient, the furnace door needs to be detached when the asbestos packing is replaced, and only the whole asbestos packing can be replaced.
Disclosure of Invention
Aiming at the problem of furnace door sealing in the smelting furnace industry, the utility model aims to provide a novel sealing furnace door structure which is simple in structure and maintenance, the sealing furnace door structure utilizes the technologies of integral welding, modular assembly, ceramic fiber module sealing, precession compression and the like, the sealing area is large, and the furnace door does not need to be detached when a sealing element is replaced, so that the sealing performance of the furnace door is improved, and the service life of the furnace door is prolonged.
The technical scheme adopted by the utility model is as follows: the utility model provides a novel sealed furnace gate on industrial smelting stove, includes furnace door frame, furnace gate sealing member and furnace gate main part, the furnace door frame is equipped with a plurality of places the bin of furnace gate sealing member, the furnace gate sealing member is the ceramic fiber module, the ceramic fiber module is placed in the bin.
Furthermore, each furnace door frame is provided with 2 or more than 2 chambers.
Further, only one ceramic fiber module is placed in the chamber.
Furthermore, each bin is provided with 2 or more than 2 module precession pressing devices for adjusting the positions of the ceramic fiber modules.
Furthermore, the module precession pressing device is a pressing component of a steel structure and consists of a movable screw, a fixed nut, a fixed support and a pressing plate.
Furthermore, the furnace door frame is a steel structure welded in a slicing mode, expansion joints are reserved on welding parts, the problem of thermal expansion of the furnace door can be effectively solved, and the furnace door frame can be used under the condition of long time and high temperature.
The furnace door sealing piece of the utility model adopts the ceramic fiber module, has large contact area and can improve the air tightness of the furnace door; when the ceramic fiber module is worn locally in the using process, the furnace door is not sealed tightly, the position of the ceramic fiber module can be adjusted by screwing the module into the pressing device, the pressing force of the ceramic fiber module and the sealing contact surface of the furnace body is improved, and the sealing function is recovered; when the ceramic fiber module is seriously worn to be incapable of being adjusted, the module can be directly taken down to be screwed into the pressing device, and the sealing performance can be recovered only by taking out the ceramic fiber module to be replaced and putting in a new ceramic fiber module.
The utility model has the advantages that: simple structure, easy maintenance, large sealing area, good sealing performance, quick replacement of sealing elements, easy operation and long service life of the furnace door.
