Abstract

The utility model discloses a burnt cover of dry coke quenching, the motor end cap comprises a cover body, lid upper portion sets up gallows, dust channel, and the lid lower extreme sets up and seals wedge portion, the sealed wedge portion outside is fixed with the sealing layer, the inside upper end of lid sets up fixed insulating layer and activity insulating layer, and the activity insulating layer is fixed with the insulating layer extension board, the insulating layer extension board slides along the slide of lid side, fixed insulating layer is fixed on the inside top of lid, fixed insulating layer all sets up the through -hole with activity insulating layer and insulating layer support, the through -hole corresponds with dust channel. The utility model has the advantages that: owing to has adopted wedge seal structure, has avoided promotion in -process flue gas and thermal leaking effectively to it is sealed respond well, and the setting of double -deck insulating layer is not only thermal -insulated effectual, and more importantly is because the damage of coke to the insulating layer can be avoided in the setting of activity insulating layer.

Description

A kind of dry quenched coke cover

Technical field

This utility model relates to smelting iron and steel technical field, a kind of coke jar cover.

Background technology

Dry coke quenching is for coke wet quenching, uses noble gas to extinguish the one of incandescent coke Coke quenching method.Dry coke quenching can recycle the sensible heat of red Jiao, improves coke quality, alleviates quenching The operation pollution to environment.

Rotary coke tank is sling from burnt tank chassis and travels to coke dry quenching furnace center by elevator, By the red burnt equipment put in coke dry quenching furnace in burnt tank.Coke jar cover is red burnt high in being used for preventing burnt tank The temperature harmful effect to elevator, prevents the device of dust from flying.The thermal insulation layer of coke jar cover uses Thickness is the heat-resisting module of zirconium matter (service life is generally higher than a year) of heat-resisting 1400 DEG C of 150mm. During work, dry quenched coke pot closes the lid on the coke being directly pressed onto burnt tank, owing to directly connecing with coke Touch, cause coke jar cover scaling loss to effectively cause frequently maintenance.Additionally, due to poorly sealed when promoting, Often result in leaking of flue gas and heat, not only cause environmental pollution, and the equipment that easily causes damages Bad.

Utility model content

For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of effect of heat insulation Good, seal tight coke jar cover, concrete technical scheme is as follows:

A kind of dry quenched coke cover, including lid, described lid top arranges suspension bracket, dedusting is led to Road, it is characterised in that: lid lower end arranges sealed wedged portion, solid outside described sealed wedged portion Surely there is sealant；The upper end of lid portion inside arranges fixing thermal insulation layer and active insulation layer, movable every Thermosphere is fixed with thermal insulation layer support plate, and described thermal insulation layer support plate slides along the slideway of lid side；Institute State fixing thermal insulation layer and be fixed on the top of lid portion inside；Described fixing thermal insulation layer and active insulation layer And thermal insulation layer support is respectively provided with through hole, described through hole is corresponding with dedusting passage.

Described thermal insulation layer support arranges lug, arranges slideway inside described lid, and described lug exists Slide in slideway.

The utility model has the advantages that: owing to have employed wedge-type seal structure, efficiently avoid The leaking of flue gas and heat in lifting process, and sealing effectiveness is good；And double thermal insulation layer Not only good heat-insulation effect is set, it is often more important that, due to the setting of active insulation layer, can avoid The coke damage to thermal insulation layer.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the structural representation that thermal insulation layer support plate coordinates with slideway.

Detailed description of the invention

Illustrating this utility model below in conjunction with the accompanying drawings, as shown in Figure 1 and Figure 2, this practicality is new Type includes that lid 1, described lid 1 top arrange and arrange ribs between suspension bracket 2, suspension bracket 2 and lid 3,4 upper ends being fixed on lid are led in dedusting, and lid lower end arranges sealed wedged portion 10, described close It is fixed with sealant 11 outside envelope wedge-shaped part 10；The upper end of lid portion inside arranges fixing thermal insulation layer 5 With active insulation layer 7, active insulation layer 7 is fixing with thermal insulation layer support plate 6, described thermal insulation layer support plate 6 Slideway 8 along lid side slides；Described fixing thermal insulation layer 5 is fixed on the top of lid portion inside； Described fixing thermal insulation layer 5 and active insulation layer 7 and thermal insulation layer support 6 are respectively provided with through hole 9, described logical Hole 9 is corresponding with dedusting passage 4.

Described thermal insulation layer support 6 arranges lug 61, arranges slideway 8, described cunning inside described lid Road 8 is made up of two bar blocks 81；Described lug 61 slides in slideway 8.

Claims

1. a dry quenched coke cover, including lid, described lid top arranges suspension bracket, removes Dirt passage, it is characterised in that: lid lower end arranges sealed wedged portion, outside described sealed wedged portion Side is fixed with sealant；The upper end of lid portion inside arranges fixing thermal insulation layer and active insulation layer, lives Dynamic thermal insulation layer is fixed with thermal insulation layer support plate, and described thermal insulation layer support plate is sliding along the slideway of lid side Dynamic；Described fixing thermal insulation layer is fixed on the top of lid portion inside；Described fixing thermal insulation layer and activity Thermal insulation layer and thermal insulation layer support are respectively provided with through hole, and described through hole is corresponding with dedusting passage.

Dry quenched coke cover the most according to claim 1, it is characterised in that: described heat insulation Layer support arranges lug, arranges slideway inside described lid, and described lug slides in slideway.
