Abstract
The utility model discloses an observation door for a heating furnace, and is invented to solve the problem that the seal effect is bad in the prior art. The observation door comprises an observation door frame and an observation door cover, wherein, one side of the observation door cover is hinged with the observation door frame through a door axis hinge device, the external surface of the other side of the observation door cover is provided with a handle; the observation door frame and the observation door cover have casting structure. By adopting the structure, the casting structure adopted by the observation door frame and the observation door cover takes place of the regular welding structure, and the defects of heat deformation, air leakage, and gas leakage in the use process are avoided. The heat efficiency of the industrial heating furnace is increased, and the purpose of realizing the energy saving and the environmental protection is reached.
Description
Technical field
The utility model relates to a kind of used for industrial furnace and sees fiery device, particularly a kind of heating furnace observation door.
Background technology
Shortcomings such as in the prior art, industrial heating furnace wall observation door has a lot of forms, but exists observation door poorly sealed mostly, is incubated badly, and opens inconvenience, and is fragile.Along with the development of industrial technology, more and more higher to modern industry reheating furnace energy-saving-environmental protection requirement, also more and more higher to the product requirement that influences reheating furnace energy-saving.Because observation door is contained on the heating furnace furnace wall, its heat insulating ability and sealing directly influence the thermal efficiency of heating furnace.Therefore, be badly in need of a kind of observation door product that can seal heat insulation new structure on the market.
The utility model content
For overcoming above-mentioned defective, the purpose of this utility model is to overcome the above-mentioned deficiency of existing product technology, and the heating furnace observation door of a kind of sealing, excellent thermal insulation performance is provided.
For achieving the above object, the utility model heating furnace observation door comprises: observation door frame and observation door lid; Side at described observation door lid is hinged by hinge and observation door frame, and the door closure outer surface of opposite side is provided with handle, it is characterized in that: described observation door frame and observation door lid are cast structure.
Further, be provided with taper inner cap heat screen in above-mentioned observation door lid, the outer surface of described inner cap heat screen and observation door hole, furnace wall outer surface are suitable.
Further, be linked with the extension draw piece at above-mentioned handle.
Further, above-mentioned extension draw piece is a spindle, is formed by the wire coiling.
After adopting said structure, observation door frame and observation door lid adopt cast structure, have substituted conventional Welding Structure, avoid temperature distortion in use, the defective of the gas leakage of leaking out.Improve the thermal efficiency of industrial heating furnace, reached the purpose that realizes energy-conserving and environment-protective, adapted to the needs of modern petrochemical industrial development.
Description of drawings
Fig. 1 is the structural representation of the utility model observation door.
Fig. 2 is vertical cross-sectional schematic of the utility model observation door shown in Figure 1.
Fig. 3 is the horizontal cross-sectional schematic of the utility model observation door shown in Figure 1.
The specific embodiment
Below in conjunction with drawings and Examples the utility model observation door is elaborated.
As shown in Figure 1 to Figure 3, the utility model heating furnace observation door comprises: observation door frame 1 and observation door lid 2; Side at described observation door lid 2 is hinged by hinge 3 and observation door frame 1, the door closure outer surface of opposite side is provided with handle 5, described observation door frame and observation door lid are cast structure, to substitute conventional Welding Structure, avoid temperature distortion in use, the defective of leaking out and leaking gas, and the whole manufacturing of observation door have been saved the work on the spot amount.
Improve further as of the present utility model, in above-mentioned observation door lid 2, be provided with taper inner cap heat screen 4, increased the insulation thickness of observation door, and the suitable raising of the outer surface of inner cap heat screen 4 and observation door hole, furnace wall outer surface the sealing of observation door, having reduced the heating furnace heat runs off, improve the thermal efficiency of heating furnace, reached purpose of energy saving.
Improve further as of the present utility model, be linked with draw piece 51, to solve the too high hot problem of observation door handle temperature at above-mentioned handle.Above-mentioned extension draw piece can be for various materials and structure, as metal or bakelite system.
As shown in Figure 2, above-mentioned extension draw piece 51 is a spindle, is formed by the wire coiling.Like this, can further reduce and hang draw piece 51 temperature, and this extension draw piece long service life.
To sum up, observation door of the present utility model has improved the thermal efficiency of industrial heating furnace, reaches the purpose that realizes energy-conserving and environment-protective, can adapt to the needs of modern petrochemical industrial development.
