Abstract
The utility model discloses a coke oven mouth protecting device in an overhaul, which belongs to the technical field of coke oven overhauling equipment and is used for protecting a coke oven mouth in an overhaul. According to the technical scheme, the protecting device comprises two supports which are placed perpendicularly, wherein a connecting hole is formed in the upper end of each support; a connecting hole is formed in each of two ends of a transverse beam and the middle of the transverse beam; the distance between the two connecting holes in the two ends of the transverse beam is greater than the diameter of a coal charging hole of the oven mouth; the two ends of the transverse beam are connected with the upper ends of the two supports by screw rods; a pull rod is vertically arranged; an adjusting hole is formed in the upper part of the pull rod and is connected with the connecting hole in the middle of the transverse beam by a screw rod; the lower end of the pull rod is welded with a plugging disk; the diameter of the plugging disk is matched with that of the coal charging hole of the oven mouth. During an overhaul, the plugging disk is placed in the oven mouth and is positioned in suspension to plug the oven mouth, thereby not only preventing high temperature gas from burning people, but also preventing broken bricks and damaged coal charging hole bases from dropping into the oven and affecting follow-up production. The coke oven mouth protecting device, which is of a detachable assembled structure, is very convenient to use, easy to manufacture and low in cost.
Description
Technical field
The utility model relates to a kind of coke furnace carbonization chamber coal port position maintenance safety guard, belongs to coke oven repair apparatus technical field.
Background technology
Coal loading port of coke oven is the position of being feeded in the coke oven operational process, after coke oven moves for some time, the coke oven coal-charging port part can be because of the loosening distortion projection of being heated, affecting the smooth and coal car of furnace roof passes through, at this moment just need to change the fire door brick, in addition, the cracking of fire door charging hole seat meeting sometimes, also need timely replacing.Yet in changing the fire door brick and changing the maintenance process of fire door charging hole seat, because of the coking chamber temperature too high, reach 1000 ℃, the danger of burn is arranged, and the maintainer can't lean on too closely, and bad brick, bad as easy as rolling off a log the falling in stove of charging hole seat, affect follow-up coke quality and dry coke quenching, charging equipment and reach safely production, therefore be necessary to develop necessary service kit, make to change the fire door brick safer with the service work of changing the fire door charging hole seat, prevent the object that drops simultaneously in stove.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of coke oven fire door maintenance safety guard, and this maintenance safety guard can prevent the danger of furnace high-temperature hot gas to people's burn, and avoiding again brickbat, bad charging hole seat to fall in stove affects subsequent production.
The technical scheme solved the problems of the technologies described above is:
A kind of coke oven fire door maintenance safety guard, it is by support, crossbeam, pull bar, the shutoff dish forms, support is two, the vertical placement, there is supporting leg the lower end of support, there is connecting hole the upper end of support, there is respectively connecting hole the two ends of crossbeam and centre, distance between the connecting hole of crossbeam two ends is greater than the coaling diameter in hole of fire door, crossbeam is connected with bolt with two support upper ends respectively by the connecting hole at two ends, pull bar is vertically placed, adjustment hole is arranged at the top of pull bar, pull bar is connected with bolt with the connecting hole in the middle of crossbeam by the adjustment hole of upper end, the lower end welding shutoff dish of pull bar, the bore dia of coalingging of the diameter of shutoff dish and fire door is complementary.
Above-mentioned coke oven fire door maintenance safety guard, the adjustment hole on described pull bar top has a plurality of, and a plurality of adjustment holes are arranged from top to bottom along the pull bar body of rod.
The beneficial effects of the utility model are:
The utility model is put in fire door and unsettled location by the shutoff dish of pull bar lower end when maintenance above furnace roof, and fire door is carried out to shutoff, has both prevented the danger of high temperature hot gas to people's burn, and having avoided again brickbat, bad charging hole seat to fall in stove affects subsequent production.The utility model is detachable packaging assembly, very easy to use, make easily, with low cost, personnel safety and the problem that affects subsequent production while having solved the maintenance of coke oven fire door, also can prevent that gas from fire-cureing and inwardly fall foreign material while overhauling for other all types of stoves, well basement port part.
The accompanying drawing explanation
