Abstract
The invention relates to a novel furnace door mechanism which comprises a furnace door mounting plate, at least two furnace door bodies and bearing connecting pieces. The furnace door mounting plate is used for mounting the furnace door bodies. The furnace door bodies are arranged on the furnace door mounting plate in sequence in the length direction of the furnace door mounting plate, elastic connecting pieces are arranged between the furnace door bodies, and sealing rings are arranged on the inner sides of the furnace door bodies and used for closing or opening a furnace opening. The bearing connecting pieces enable the furnace door mounting plate and the furnace door bodies to be connected and used for applying free force to the furnace door bodies so as to enable the furnace door bodies to be freely attached and sealed on the furnace opening. The furnace door bodies are connected through the elastic connecting pieces, the situation that furnace doors are deformed due to too high temperature is avoided, the sealing effect is good, running fire is prevented from occurring in the furnace door opening, energy losses are reduced, and therefore production cost is lowered. The attachment degree of the furnace door bodies and the furnace opening can be automatically adjusted through the bearing connecting pieces, furnace door opening iron castings and sealing strips are prevented from being damaged, and the service life of the iron castings and the sealing strips is prolonged.
Description
Technical field
The invention belongs to industrial furnace mechanical field, relate in particular to a kind of furnace door mechanism.
Background technology
Industrial furnace temperature in body of heater when work is very high, and the capacity of industrial furnace is also increasing, and the specification of industrial fire door also becomes large thereupon.Therefore, be easy to distortion after fire door is heated, particularly for Large Furnace door, because stove gate sealing after fire door distortion is bad, fire door does not press tightly, and causes the runout of stove gate place.Energy does not only reclaim by heat exchanger, directly discharges out of the furnace, and causes the waste of energy and the pollution of environment, has reduced the efficiency of industrial furnace yet, has increased input cost; On the other hand, accelerate the damage of stove gate ironcasting and sealing strip, shortened the life-span of ironcasting and sealing strip.
Therefore, need a kind of fire door mechanism of good sealing effect badly.
Summary of the invention
The object of the invention is to overcome the defect that prior art exists, a kind of furnace door mechanism is provided.
The technical scheme that realizes the object of the invention is: a kind of furnace door mechanism, comprising:

At least two oven door body, described oven door body is set in turn on described fire door installing plate along fire door installing plate length direction, between described oven door body, be provided with Flexible Connector, described oven door body inner side is provided with sealing ring, for closed or open body of heater mouth;
Bearing connection, is connected described fire door installing plate with described oven door body, for apply free force to oven door body, make the free gluing, sealing of oven door body to body of heater mouth.
Further, described Flexible Connector is fiber block.
Further, described bearing connection comprises bearing, connecting axle and bearing, described bearing is arranged in described fire door installing plate and is arranged in described oven door body, and described connecting axle is arranged on described bearing, and described bearing is arranged on described connecting axle and with described oven door body and is connected.
Further, described bearing is radial bearing.
Further, be also provided with bearing spacer on described connecting axle, described bearing spacer is arranged between described connecting axle and described bearing.
Further, described oven door body top is articulated with on body of heater mouth, and described oven door body and horizontal plane angle of inclination A arrange, and described angle A is 60～90 °.
Further, also comprise for promoting the lift cylinder of oven door body and for oven door body being compacted to the compressed oil cylinder on body of heater mouth.
The present invention has positive effect: in the present invention, a plurality of oven door body connect by Flexible Connector, compared to prior art, prevents that fire door from producing distortion because of excess Temperature, good sealing effect, avoid stove gate to produce runout, reduced the loss of energy, thereby reduced production cost; Oven door body is installed on fire door installing plate by bearing connection, can automatically regulate the laminating degree of oven door body and body of heater opening, has avoided the damage of stove gate ironcasting and sealing strip, has extended the service life of ironcasting and sealing strip.
