Description

Clean type heat reclamation coke furnace door

Technical field

It the utility model is related to one kind and move horizontally counterweight self-tightening type clean type heat reclamation coke furnace door, belong to coke oven skill Art field.

Background technology

The 1980s, foreign countries began one's study free of contamination coking process, and a kind of new coke oven starts input life Production, here it is clean type heat recovery coke oven, the maximum difference with traditional coke oven is its negative-pressure operation, fired completely in fugitive constituent stove Burn.This coking process avoids the loss of pernicious gas, protects environment.

China develops in nineteen nineties to heat recovery coke oven, though starting is a little later, quickly in the world Achieve leading superiority, multinomial technology be all it is pioneering, such as：Hydraulic pressure tamping technology；Flush burnt technology etc..It is short due to its spatter property Short coke oven this during the decade just achieves huge development in China and gone to the world, especially in environment than more sensitive Area.

The fire door closing mode of current cleaning Formed Coke Furnace, which generally uses, is fixed on door upper part（Or bottom）Guide wheel ( Referred to as roller)) it is placed on when closing fire door on the surface rail being fixed on protection board, surface rail supports the weight of fire door, stove The component of door weight makes fire door automatic impaction on protection board, fire door bottom（Or top）Compressed with wedge-shaped plate.By upper and lower Pressurizeed to fire door, compress the asbestos cord on fire door and have the function that to seal carbonization chamber.

The problem of this breech lock mode is present：The 1st, although current clean type coke oven door is also needed using mechanically actuated Will by manually beat pull out, wedge anchorage shape plate, 100 ~ 200 DEG C of fire door outside wall temperature, fire door radiate cause environment temperature it is higher, Worked under this operating environment, labor strength is big.When the 2nd, opening fire door, the movement locus of fire door is that fire door is first lifted up, Then move horizontally laterally.Movement locus when closing fire door is that fire door is first moved horizontally and is pressed on protection board, then again Fire door is put down.Fire door does vertically movable under impaction state in the action moment of opening and closing, fire door relative to protection board.This Sample, which can make to be fixed on the ceramic fibre material to seal on fire door or protection board, to come off, and increases oven door sealing workload. 3rd, fire door is huge thick and heavy, due to operation inconvenience.It is vertically movable during door opening and closing, for upper and lower split fire door, may collide Fire door, for single door structure, protection wall that may be behind crash protection plate and protection board causes coke oven ironware, door lining The destruction of refractory material or body of heater.In order to avoid collision, the original gap of coke oven door herein typically in 40-70mm or so, Heat radiation deforms by this gap fire door and the protection board contacted with fire door, cause causing Jiao that leaks out, reduce coke Quality and yield.The damage of fire door and protection board can be caused under heat radiation long term.

Utility model content

To solve technical problem existing for prior art, the utility model provide it is a kind of simple in construction, without artificial behaviour Make, the one kind for reducing the labor intensity of worker moves horizontally counterweight self-tightening type clean type heat reclamation coke furnace door.

To achieve the above object, technical scheme is that one kind moves horizontally the cleaning of counterweight self-tightening type used by the utility model Type heat reclamation coke furnace door, including oven door body, the surrounding of the oven door body are provided with keeper self-tightening mechanism, the door Bolt self-tightening mechanism is mainly made up of roller, connecting rod, rotating stand and take-up device, and the rotating stand is fixed on oven door body On, the link rotatable is arranged on rotating stand, and one end of the connecting rod is rotatablely equipped with roller, and tension is provided with connecting rod Device, the take-up device are used to control keeper self-tightening mechanism to compress fire door, and the roller is stuck on keeper hook.

Preferably, the take-up device is counterweight or spring, and the counterweight or spring are arranged on the end of connecting rod, for driving Connecting rod rotates around rotating stand.

Preferably, the rotating stand is mainly made up of bearing block and rotating shaft, and the rotating shaft is arranged in bearing block, described Connecting rod is fixed in rotating shaft.

Preferably, clapboard is provided with the keeper hook, the roller rolls along clapboard, for compressing fire door, institute Keeper hook is stated to be fixed on furnace stay or protection board.

Preferably, the torque arm length of the take-up device is more than the torque arm length of roller.

Preferably, at least provided with 3 hooks in the oven door body.

Preferably, the motion track of the oven door body is to move horizontally.

The utility model so uses, and clean type heat recovery coke oven is when coaling coke-removing opens fire door, coke over machinery （Coal-charging pusher machine and coke quenching car）Door extractor first give one pretightning force of fire door, then lift the counterweight of door bolt mechanism, allow Lever is deviate from together with roller from keeper hook, and then the horizontal hauling-out of fire door is thus opened fire door by coke over machinery.Close During fire door, coke over machinery is the horizontal feeding of fire door, and after protection board contact, gives fire door pretightning force compressed ceramic fibrous encapsulation material Material, after reaching seal request, puts down counterweight, reaches self-tightening sealing by the weight of counterweight, the setting of roller reduces coefficient of friction It can ensure freely to reach self-tightening sealing in the presence of counterweight.

Meanwhile the movement locus of coke oven door is moves horizontally, can so avoid being fixed on risen on fire door or protection board it is close The ceramic fibre material of envelope effect comes off, and reduces manual seal, can reduce upper furnace door and lower furnace door again（Or single fire door and Jiao Stove ironware, door lining refractory material）Between gap, avoiding heat radiation causes fire door and the protection board contacted with fire door to become Shape, avoid the reduction that air enters the quality and yield of coke caused by causing Jiao.It is prior to be that of avoiding in heat Radiate the damage of fire door and protection board caused by meeting under long term.

The utility model can both realize that fire door was locked in mechanization, reduce the manual operation under hot environment, again can be with Coke oven ironware and body of heater is protected not to be impacted, it is often more important that the effective sealing for improving fire door, reduce the scaling loss of coke, Solve the sealing under the clean type heat recovery coke oven negative-pressure operation of long-standing problem and change burnt problem, extend making for coke oven door Use the life-span.

Compared with prior art, the utility model has following technique effect：

1st, it is simple in construction, mechanized operation, reduce the labor intensity of worker.

2nd, the sealing of fire door is improved, reduces coked burnt rate.

3rd, the service life of coke oven door is extended.
