Abstract
The utility model belongs to heat recovery coke oven devices, and particularly relates to a heat recovery coke oven upper oven door edge knife device which mainly solves the problems that an upper oven door leaks and production is affected due to the fact that existing upper oven door composite aluminum silicate wool can fall off easily. The heat recovery coke oven upper oven door edge knife device comprises an upper oven door, composite aluminum silicate wool is arranged in a door frame of the upper oven door, a layer of reinforced plate is arranged outside the door frame of the upper oven door, and a plurality of fastening bolts are arranged outside the reinforced plate. With the technical scheme, the heat recovery coke oven upper oven door edge knife device fundamentally solves the technical problems of coking of portions, on a machine side and a coke side, of a furnace head due to the facts that sealing of the coke oven upper oven door is not tight and cold air enters.
Description
Technical field
The utility model belongs to the heat recovery coke oven device, is specifically related to a kind of heat recovery coke oven upper furnace door knife-edge device.
Background technology
QRD-2000 type heat recovery coke oven fire door is divided into upper furnace door and lower furnace door, in normal production process, maintain the gap of 50mm left and right between upper lower furnace door, what the sealing of upper furnace door was adopted is that complex silicate is cotton, coke oven is after operation for some time, the complex silicate cotton can produce obscission under the condition of high temperature, cause the coke oven upper furnace door to produce gas leak phenomenon, sometimes lower furnace door can collide upper furnace door unavoidably in the process of the discharging of the coke, thereby also can cause the unordered pressures inside that enters of freezing air, not only cause the coke oven end temperature to descend, and what is more important to increase the change of mechanical coke both sides burner burnt.
Summary of the invention
The utility model easily comes off mainly for existing upper furnace door complex silicate cotton, causes upper furnace door gas leakage, the problem that impact is produced, provide a kind of simple in structure, prevent the heat recovery coke oven upper furnace door knife-edge device that leaks gas.
The utility model is to address the above problem the technical scheme of taking to be:
A kind of heat recovery coke oven upper furnace door knife-edge device comprises upper furnace door, wherein: be provided with the complex silicate silk floss in the upper furnace door doorframe, and be provided with one deck gusset plate outside the upper furnace door doorframe, be provided with some holding bolts outside gusset plate.
The utility model adopts technique scheme, by upper furnace door knife-edge device, has solved fundamentally that the coke oven upper furnace door is poorly sealed, freezing air enters, and causes machine, burnt both sides burner Jiao's technical barrier.
Description of drawings
Fig. 1 is structural representation of the present utility model.
