The lower furnace door 2 comprises a furnace door body 5 and four cast iron bars 6 which are respectively provided with a dovetail groove 7. Ceramic fiber flat ropes are arranged in the dovetail grooves 7. The utility model changes the sealing type of the furnace door from hard surface contact into flexible sealing, solves the problems of untight sealing and unorganized air supply of the coke furnace, lowers the coking rate, increases the full coke production rate and reduces the resource wastage.
Description
One, technical field
The utility model belongs to a kind of coke oven door, is specifically related to a kind of clean type heat reclamation coke furnace door.
Two, background technology:
At present, environmental requirement both at home and abroad all increases, Shanxi Province in 2000 chemical design institute's independent research environment protecting QRD-2000 clean type heat recovery tamping type coke oven preferably.The clean type heat recovery tamping type coke oven of building that started both at home and abroad till now from 2000 has family more than 80, but because this type of furnace negative-pressure operation, oven door sealing requires tighter, this technology belongs to a kind of new things, new technique again simultaneously, not overripened, oven door sealing adopts rigidity to seal firmly always, and sealing effectiveness is poor, occurred having caused the wasting of resources and business economic benefit to reduce because of from the burnt serious problem of fire door unorganized air supply bigization of amount.
Three, summary of the invention:
The utility model is exactly to solve existing clean type heat recovery tamping type coke oven oven door sealing weak effect, big, the burnt serious problem of change of unorganized air supply's amount.
The utility model is achieved through the following technical solutions: a kind of clean type heat reclamation coke furnace door, comprise upper furnace door 1, lower furnace door 2, last protecting sheet 9, middle protecting sheet 10, following protecting sheet 11, upper furnace door 1 is provided with protecting sheet 9, lower furnace door 2 both sides are provided with middle protecting sheet 10, lower furnace door 2 has down protecting sheet 11, the lower edge width of upper furnace door 1 equals the width of coking chamber, the lower edge height of upper furnace door 1 is parallel to protecting sheet 9, upper furnace door 1 upper edge is provided with segmental arc 3, and last segmental arc 3 is provided with half-arc groove 4, is provided with braided asbestos round packing in the half-arc groove 4; Lower furnace door 2 is made up of the detachable cast iron bar 6 of oven door body 5 and four band dovetail-indents 7, and the detachable cast iron bar 6 of band dovetail-indent 7 connects with oven door body 5 by heat-resisting bolt 8, is provided with the ceramic fiber flat rope in the dovetail-indent 7.Dovetail-indent 7 be shaped as the isosceles trapezoid that the bottom is big, top is little.
The utility model compared with prior art has following beneficial effect: by the improvement of door structure and oven door sealing material, make the oven door sealing form change flexible sealing into, former rigid contact seal is tight, leakage is serious, the present situation of coke oven unorganized air supply thereby change, the burnt rate of reductionization, improve full coke yield, reduce the wasting of resources, improve business economic benefit and social benefit.
