Description
Technical field
The utility model is related to a kind of observation door used for industrial furnace, more particularly to a kind of stove high-temperature energy-conservation observation door.
Background technology
At present along with oil refining apparatus, chemical plant installations large-scale development, the industrial furnace structure in each field gradually maximizes, stove
Bore temperature more and more higher, can reach 1200 DEG C.Old type tube observation door in the past is generally used for work of the fire box temperature no more than 800 DEG C
Industry stove, when high temperature industrial furnace, observation door surface temperature can be very high, is unfavorable for safety operation, and burner hearth heat passes through
Observation door is distributed to environment, causes the waste of energy.So the observation door set on high temperature industrial furnace needs to see fire in satisfaction
More preferable heat-insulating and sealing effect is provided while condition, beneficial to safety and energy-conservation.
It is on the basis of original common observation door, to increase using the observation door with flame-observing hole plug in prior art one
One flame-observing hole plug, more preferable effect of heat insulation is provided by flame-observing hole plug, is opened after observation door, it is necessary to extract flame-observing hole out again
Plug, normally can just check inside burner hearth；, it is necessary to first be put into flame-observing hole plug when closing observation door, observation door is turned off.
The shortcoming of prior art one is：The opening and closing of observation door are required for two steps to operate, while flame-observing hole is beyond the Great Wall
Draw ring temperature can reach 300 DEG C, it is necessary to additional means can just take out, operation inconvenience, while stopple high temperature is easily hurted sb.'s feelings, exist
Potential safety hazard.
In prior art two, using the observation door with pyroceram, be increased in observation door one piece it is resistant to elevated temperatures
Glass, burner hearth is observed when opening observation door through glass.
The shortcoming of prior art two is：This kind of structure observation door high temp glass form is once adhered to by the flue dust in burner hearth,
Only can just be cleared up when blowing out, otherwise cannot again meet and see fiery requirement.In order to avoid blowing out, need to be in observation door
Place sets flue pipe purging form inwall, and supporting air purge system complex structure increased manufacturing cost and operation difficulty, together
When timing purging cause burner hearth air capacity increase, flue gas loss increase, reduce thermal efficiency of heating furnace.
The content of the invention
It is high that the purpose of this utility model is to provide the stove that a kind of safe operation, industrial furnace heat scatter and disappear less, the thermal efficiency is high
Warm energy-conservation observation door.
The purpose of this utility model is achieved through the following technical solutions：
Stove of the present utility model high-temperature energy-conservation observation door, including doorframe, door closure, side and the doorframe of the door closure pass through
Multi link is connected, and the multi link connection includes that many connecting rods are hinged rear its two ends and are cut with scissors with the doorframe and door closure respectively successively
Connect, the liner thickness on the inside of the door closure is more than the liner thickness on the inside of the doorframe.
The technical scheme provided by above-mentioned the utility model is as can be seen that the stove high temperature of the utility model embodiment offer
Energy-conservation observation door, due to covering the lined thickness of increasing in observation door, and facilitates door closure using the connected mode of multi link
Operation, first straight line is extracted out when the connected mode of multi link can allow door closure to be opened, lateral opening, solution again after lining is completely drawn out
High temperature observation door heat insulation effect of having determined is not good, the problem of overtemperature；The increase of observation door liner thickness is solved, brings unhandy
Problem；Ensure observation door safety operation, reduce industrial furnace heat and scatter and disappear, improve the thermal efficiency.

Specific embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out clearly
Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole realities
Apply example.Based on embodiment of the present utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made
The every other embodiment for obtaining, belongs to protection domain of the present utility model.
Stove of the present utility model high-temperature energy-conservation observation door, preferably specific embodiment is as shown in Figures 1 to 4 for it：
Including doorframe, door closure, the side of the door closure is connected with doorframe by multi link, and the multi link connection includes many
Its two ends is hinged with the doorframe and door closure respectively after root connecting rod is hinged successively, and the liner thickness on the inside of the door closure is more than described
Liner thickness on the inside of doorframe.
The multi link is connected by the connected mode of the axle of double link three.
Anchor studs are provided between the inner side of the door closure and lining.
The lining use MULTILAYER COMPOSITE lining, including following any multilayer compound lining：Ceramic fibre and castable
Composite construction, composite ceramic fiber article construction, low thermal conductivity material.
The lining preferably uses two-layer composite.
Stove of the present utility model high-temperature energy-conservation observation door, the lined thickness of increasing is covered in observation door, and use connects more
The connected mode of bar facilitates the operation of door closure, and first straight line is extracted out when the connected mode of multi link can allow door closure to be opened, wait to serve as a contrast
In be completely drawn out after lateral opening again.The connected mode of multi link ensures the multiple degrees of freedom of door closure motion, if using conventional door
