[0002] The heating furnace door mechanism is an important component of the heating furnace. Its design structure and thermal insulation performance are crucial to the energy consumption of the heating furnace and the overall operating efficiency of the equipment.

[0003] The existing heat insulation door structure is welded steel plate, and ceramic fiber is filled inside for insulation; the outside adopts flexible connection method, and the outside adopts sprocket method for indirect drive; the furnace door adopts steel plate welding structure, and the welding part is easy to fail in a high temperature environment with atmosphere for a long time, which causes the furnace door to deform or be damaged, making the equipment unable to operate normally;

However, in a long-term high temperature environment, this connection method has multiple mechanism instabilities, and is prone to fractures at the connection and welding failures. In addition, the traditional detection method usually adopts an indirect detection method, which is prone to misdetection due to the flexible connection method. Therefore, a new structure is needed to solve the above technical difficulties. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.

[0025] The novel durable heat-insulating door mechanism comprises a furnace door lifting system mounting frame 4 located on the heating furnace body 1, a lifting drive power group 5 is fixedly installed on the upper side of the furnace door lifting system mounting frame 4, a lifting drive rack 6 is provided on the furnace door lifting system mounting frame 4, the lifting drive rack 6 is mechanically connected to the lifting drive power group 5, a rigid connecting shaft 7 is fixedly installed at the lower end of the lifting drive rack 6, the rigid connecting shaft 7 is made of heat-resistant material, and will not break or fail at the connection when used for a long time in a high-temperature environment with atmosphere; a casting door frame 8 is fixedly installed at the lower end of the rigid connecting shaft 7, and the casting door frame 8 is located in the heating furnace body 1;

[0026] It should be noted that a casting door frame 8 is used between the low-temperature treatment area 3 and the high-temperature treatment area 2. Since the casting door frame 8 adopts an integrated casting molding, there is no welding at the connection of the casting door frame 8. Due to the particularity of casting, the casting door frame 8 can work effectively for a long time in the high temperature environment inside the heating furnace body 1.

[0027] As a technical optimization solution of the utility model, the furnace door lifting system mounting frame 4 is provided with a position detection system 9, and the position detection system 9 is slidably connected with the lifting drive rack 6;

[0028] It should be noted that the position detection system 9 is installed on the outside of the furnace door lifting system mounting frame 4.

[0032] It should be noted that the specific connecting shaft buffer mechanism 11 is a gap.

[0034] It should be noted that the casting door frame 8 and the lifting drive power group 5 are connected by a rigid connecting shaft 7, and a mounting frame insulation layer 13 and a connecting shaft sealing system 12 are provided on the furnace door lifting system mounting frame 4 to ensure the insulation and sealing of the furnace door installation position.

[0035] The technical solution adopts an integrated casting structure of the casting door frame 8, instead of the ordinary welding structure, so that the cold can be used stably for a long time in the high temperature environment of the furnace; a rigid connecting shaft 7 is used instead of a flexible connecting part, compared with the flexible connecting part structure; the service life and stability of the rigid connecting shaft 7 are better; at the same time, a direct detection method is adopted to ensure the accuracy of the position detection of the casting door frame 8.

[0036] The above describes the utility model and its implementation methods, which are not restrictive. The specific implementation method is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
