Abstract
On the fire door of pit kiln, be useful on even paperback charcoal rear surface and insert the fenestella that leveller is used.This fenestella seals by wicket, the present invention relates to this fenestella, around fenestella, center on level and smooth frame is arranged, wicket is installed by linkage, can open and close in the horizontal direction freely oven door body, inboard at wicket, promptly towards a side of fenestella that one usefulness metal sheet is made, size being housed can the positive barrier film that covers fenestella, the fire door edge of a knife towards above-mentioned frame is housed around this is membranous, fire door edge of a knife rear end is pressed on the frame side with plunger, is provided with between barrier film and the wicket body to allow the space of extraneous air free flow.
Description
The present invention relates on the fire door of closing the pit kiln inlet, be the used wicket of the fenestella of closing the door upper part opening.
The fire door that pit kiln is used, the purpose for upper strata coke in the even stove is provided with fenestella in door upper part, will be known as the flat material bar fenestella insertion from then on of leveller.
Being used for closing the wicket of fenestella in the past, is closing condition usually, only just need open when leveller inserts.Therefore by linkage it is installed on the oven door body comfortablely, and blocking mechanism is housed, it can not be opened after closing simply.In addition, with the purpose of outside atmosphere, the sealing property that improves wicket is a research topic in the blocking stove.
The seal means in past is to make the containment member that is called the fire door edge of a knife of little reveal and the frame around the fire door fenestella be metallic contact, but when using this fire door edge of a knife and framework to seal, exist owing to bear the influence of high temperature and internal-external temperature difference repeatedly, produce the gap.Exist gas leakage from here to cause the problem of public hazards.
The objective of the invention is to propose a kind of wicket with door for coke oven of the sealing mechanism that is difficult for the generation gap.
For achieving the above object, the present invention who is proposed is constructed as follows described:
Around fenestella, center on level and smooth frame is arranged;
The wicket body is installed by linkage, but relative oven door body horizontal direction freely openable;
In the inboard of wicket body, promptly, barrier film is set in the face of little reveal, its size is topped firmly fenestella from the front, is processed into by a metal sheet, towards above-mentioned frame the fire door edge of a knife is housed around this barrier film;
The rear end of the fire door edge of a knife is pressed on frame one side with plunger;
Between barrier film and wicket body, be provided with space with the extraneous air free flow.
Below in conjunction with accompanying drawing, further specify the present invention by description to embodiment.
Figure (1) is the front view of door for coke oven,
Figure (2) is the front view of little door section,
Figure (3) is an A-A ' line sectional view.
Accompanying drawing has been represented most preferred embodiment of the present invention.
Figure (1) be the front of door for coke oven, 1 bolt of using when being loaded on pit kiln for oven door body 1, and the 3rd, be the fenestella that inserts leveller, 4 is the wicket of airtight this fenestella, but this wicket passes through linkage 5 freely openables, and its concrete structure is shown in Fig. 2,3.
In Fig. 2,3,6 barrier films of making for the stainless steel that is configured in wicket 4 inboards (sealing plate) are equipped with the fire door edge of a knife 7 facing to fire door 1 one side frame 1a around this barrier film 6.
8 for being depressed into the fire door edge of a knife 7 plunger that needs from the rear end, 9 is mandrel, and 10 for extruding the spring of this mandrel 9, and 11 is the air cooling space that forms between wicket body 4 and the barrier film 6.12 is the leveller hole of body 1 one sides in the stove among the figure, and 13 is seal strip, and 14 is that the fire door edge of a knife, 15 is firedoor frame.
In addition, A is the state of wicket 4 when opening to view among Fig. 3.
Said structure wicket 4 as shown in Figure 3, covers fenestella with barrier film 6, seals sealing fenestella 3 with the fire door edge of a knife 7.Barrier film 6 by means of the plunger 8 pushing fire door edges of a knife 7, stops the disengaging of the fire door edge of a knife 7 ends from frame 1a by the strain of its elastic contribution absorption corresponding to thermal stresses, prevents to produce the gap.
The present invention is as described below, owing to use the inboard airtight fenestella of using on the topped door for coke oven of wicket of barrier film that is equipped with, therefore, following utilizability is arranged industrially.
A. because barrier film has elasticity, can well absorb the thermal stress of wicket one side and frame one side, stop between the fire door edge of a knife and the frame to produce the space. Its result does not worry gas leakage, can effectively prevent public hazards.
B. a barrier film is easy to cleaning.
C. a metal diaphragm is easy to processing, and is in light weight.
D. be provided with the air cooling space between wicket body and barrier film, therefore by the air cooling effect, the thermal deformation of wicket body is little.
Claims (1)
