Description

A kind of telescopic joint arch crown refractory brick
Technical field
It the utility model is related to thermal insulation fire-resistant article technology, more particularly to a kind of telescopic joint arch crown refractory brick.
Background technology
In dry coke quenching auxiliary, coke oven release about 1 000 DEG C of coke with nitrogen circulation cool down 250 DEG C or so after, Burnt tank is discharged from lower cone bucket.Through cell-type deduster dedusting, and with waste heat boiler recovery heat steam occurs for circulating nitrogen gas, then passes through Secondary cyclone device is sent into coke quencher by air blower after dedusting again and recycled.The refractory material of dry coke quenching auxiliary is because for a long time by height Temperature, air blast, coke friction etc. influence, and by serious etch and wash away.One time cell-type deduster connects with coke dry quenching furnace, boiler Two telescopic joint refractory materials damage especially severe, be dry coke quenching production weak link.
Easily burnt at the top of telescopic joint side wall and arc and castable comes off, the reason for this is that:Telescopic joint both sides dilatation joint The filling leakiness of refractory filler.There is certain negative pressure inside when coke dry quenching furnace produces, have absorption for dilatation joint inner stuffing Power, after the filler in dilatation joint is sucked away, the pressure of coke dry quenching furnace, high temperature by dilatation joint gap directly with telescopic joint Metal part, heat-insulation layer contact, such metal part easy burn-out, the castable of telescopic joint heat-insulation layer are also burned off, anchoring piece Due to being directly in the condition of high temperature, the castable of rear destruction work layer is deformed.The castable of working lining and heat-insulation layer is destroyed Afterwards, the metal of telescopic joint easily burns, burnt out, or even the whole telescopic joint of damage.
Utility model content
The utility model purpose is to provide a kind of telescopic joint arch crown refractory brick, and production operation situation is good again for coke dry quenching furnace It is good, meet the purpose of dry coke quenching production.
Working lining mullite brick at the top of a kind of telescopic joint arch crown refractory brick described in the utility model, including telescopic joint, institute The left and right sides for stating working lining mullite brick at the top of telescopic joint is provided with telescopic joint dilatation joint, the working lining mullite at the top of telescopic joint The middle of the top of brick is provided with dilatation joint tooled joint clay brick at the top of telescopic joint, the dilatation joint tooled joint clay brick at the top of telescopic joint Both sides are provided with heat-insulation layer High-Alumina light-weight brick at the top of telescopic joint;The top of working lining mullite brick is provided with flexible at the top of telescopic joint Framework is saved, is provided with the both sides of telescopic joint framework at the top of telescopic joint and backfills heat-insulating granules layer, stratum granulosum is backfilled at the top of telescopic joint Top is provided with furnace shell at the top of disposable dust remover, and steel plate protective case at the top of telescopic joint is provided with the top of telescopic joint framework.
Further, the width of described telescopic joint dilatation joint is 45mm.
Further, in described telescopic joint dilatation joint filling operating temperature be 1260 DEG C, density be 220 kg/m3's Ceramic fiber blanket.
The beneficial effects of the utility model are:
1st, the utility model is by the change to the resistance to material structure of cork dry quenching disposable dust remover telescopic joint, to telescopic joint by above-mentioned After method transformation, using the structure type of refractory brick during dry coke quenching structure design, production operation situation is good again for coke dry quenching furnace, The purpose of dry coke quenching production is met, the dry coke quenching annual overhaul time is effectively shortened, substantially prolongs making for dry coke quenching telescopic joint With the life-span, solves the weak link that dry coke quenching produces.
2nd, during welding steel protective case, in order to protect expansion energy-saving free wxpansion and contraction, steel plate is only welded on telescopic joint One side of framework, another side directly overlap upper 100 mm.
3rd, telescopic joint both sides dilatation joint refractory filler packwork temperature be 1260 DEG C, density be 220 kg/m3's It is closely knit to reach dilatation joint inner stuffing more than 40 % for ceramic fiber blanket, the compression ratio of ceramic fiber blanket;Solves prior art Problem caused by the filling leakiness of filler.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
The utility model is done with reference to the accompanying drawings and detailed description and further illustrated.
As described in Figure 1, working lining mullite brick 1 at the top of a kind of telescopic joint arch crown refractory brick, including telescopic joint, it is described flexible The left and right sides of section top working lining mullite brick is provided with telescopic joint dilatation joint 2, the working lining mullite brick at the top of telescopic joint The middle of top is provided with dilatation joint tooled joint clay brick 4, the two of dilatation joint tooled joint clay brick 4 at the top of telescopic joint at the top of telescopic joint Side is provided with heat-insulation layer High-Alumina light-weight brick 3 at the top of telescopic joint;The top of working lining mullite brick is provided with flexible at the top of telescopic joint Framework 7 is saved, is provided with the both sides of telescopic joint framework at the top of telescopic joint and backfills heat-insulating granules layer 5, particle is backfilled at the top of telescopic joint Layer top is provided with furnace shell 6 at the top of disposable dust remover, is provided with steel plate protective case 8 at the top of telescopic joint in the top of telescopic joint framework, stretches Steel plate protective case extends 100mm to the right side of telescopic joint framework at the top of casing coupling.
