Abstract
The invention discloses a heating furnace fire observing door which comprises a door cover, a door frame and a handle. The door cover is connected with the door frame in a rotating mode. One end of the handle is connected with the door frame in a rotatable mode. A rotating axis between the door cover and the door is perpendicular to a rotating axis between the handle and the door frame. When the door cover is in a closed state, the handle is arranged above the door cover along a rotating path of the rotating shaft. A wedge-shaped block is connected with the handle and connected with one side, close to the door cover, of the handle. The smaller end of the wedge-shaped block directs toward to a rotating shaft of the handle. The structure of the heating furnace fire observing door not only retains advantage of a side open type, but also overcomes defect that the existing heating furnace fire observing door is not convenient to seal. Due to the fact that the long rotating handle with the wedge-shaped block is adopted, the door cover and the door frame can be tightly compressed, and not only is force saved, but also reliability is achieved. In order to further improve sealing property, a seal groove is formed in the door frame, a seal cushion is arranged inside the seal groove, and therefore the fire observing door is enabled to achieve good sealing property.
Description
Technical field
The technical program belongs to boiler component, specifically a kind of heating furnace observation door.
Background technology
Observation door is one of requisite parts of heating furnace, and it is to observe the heating furnace combustion case, and heated equipment (boiler tube) safety whether, and then the important evidence of regulating heating furnace as operation.
The form of observation door is numerous, and observation door pattern relatively more commonly used on large-scale pyrolysis furnace has following two kinds:
1, upper open type observation door: this observation door relies on gravity that badge is lived, and reaches the effect of sealing.But door capable of being opened is sometimes harder, also is difficult to carry out heat insulation to peephole, and some employing peephole stoppers are in addition adiabatic, use not too convenient (seeing upper right figure).
2, laterally opened observation door: this observation door is laterally opened, and the keying of door is more convenient, and adopts the structure (seeing upper right figure) that carries the peephole heat insulation, and is good to the insulation effect of peephole.But the sealing of observation door is to utilize the bayonet socket of handle and doorframe to compress, and this machining accuracy to parts is high, and the situation that is difficult to block is often arranged.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the technical program proposes a kind of heating furnace observation door, and concrete technical scheme is as follows:
A kind of heating furnace observation door comprises door closure, doorframe and handle; Door closure and doorframe are rotationally connected; One end and the frame door of handle are rotationally connected; Between door closure, doorframe between pivot center and handle, doorframe pivot center mutually vertical; Under the door closure closed condition, handle along the rotation path of its rotating shaft above door closure.Be connected with wedge type block on described handle, this wedge type block is connected to close door closure one side of handle, and a less end of wedge is towards the rotating shaft of handle.
Described door closure outer surface is provided with arc bump; The projection centre position is higher than position, projection both sides.
Described door closure inner surface is provided with thermal insulation layer, thermal insulation layer.
Be provided with in seal groove, seal groove with corresponding position, door closure position on described doorframe sealing gasket is housed, under the door closure closed condition, door closure and sealing gasket are closely connected.
Novel observation door structure is to have kept laterally opened advantage, overcome again the shortcoming of inconvenient sealing, adopted on the structure with wedge and rotated nigger, can very laborsavingly reliably door closure and doorframe be compressed again, in order further to improve sealing, be provided with seal groove on doorframe, built-in gasket makes observation door accomplish fabulous sealing.

The specific embodiment
A kind of heating furnace observation door comprises door closure, doorframe and handle; Door closure and doorframe are rotationally connected; One end and the frame door of handle are rotationally connected; Between door closure, doorframe between pivot center and handle, doorframe pivot center mutually vertical; Under the door closure closed condition, handle along the rotation path of its rotating shaft above door closure.Be connected with wedge type block on described handle, this wedge type block is connected to close door closure one side of handle, and a less end of wedge is towards the rotating shaft of handle.Described door closure outer surface is provided with arc bump; The projection centre position is higher than position, projection both sides.Described door closure inner surface is provided with thermal insulation layer, thermal insulation layer.Be provided with in seal groove, seal groove with corresponding position, door closure position on described doorframe sealing gasket is housed, under the door closure closed condition, door closure and sealing gasket are closely connected.
