Abstract
The present invention relates to a kind of furnace door mechanism, comprising: fire door installing plate, for installing oven door body; At least two oven door body, oven door body is set in turn on fire door installing plate along fire door installing plate length direction, is provided with Flexible Connector, is provided with sealing ring inside oven door body between oven door body, for closing or opening body of heater mouth; Bearing connection, is connected fire door installing plate with oven door body, makes the free gluing, sealing of oven door body to body of heater mouth for applying free force to oven door body.In the present invention, multiple oven door body is connected by Flexible Connector, prevents fire door Yin Wendu too high and produces distortion, good sealing effect, avoids stove gate to produce runout, reduces the loss of energy, thus reduce production cost; Bearing connection can regulate the laminating degree of oven door body and body of heater opening automatically, avoids the damage of stove gate ironcasting and sealing strip, extends the service life of ironcasting and sealing strip.
Description
Technical field
The invention belongs to industrial furnace mechanical field, particularly relate to a kind of furnace door mechanism.
Background technology
The temperature of industrial furnace operationally in body of heater 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 after fire door distortion, stove gate sealing is bad, fire door does not press tightly, and causes stove gate place to run away.Energy is not only reclaimed by heat exchanger, directly discharges out of the furnace, and causes the waste of energy and the pollution of environment, also reduces the efficiency of industrial furnace, add input cost; On the other hand, accelerate the damage of stove gate ironcasting and sealing strip, shorten the life-span of ironcasting and sealing strip.
Therefore, a kind of fire door mechanism of good sealing effect is needed badly.
Summary of the invention
The object of the invention is the defect overcoming prior art existence, a kind of furnace door mechanism is provided.
The technical scheme realizing the object of the invention is: a kind of furnace door mechanism, comprising:
Fire door installing plate, for installing following oven door body;
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, be provided with Flexible Connector between described oven door body, inside described oven door body, be provided with sealing ring, for closing or opening body of heater mouth;
Bearing connection, is connected described fire door installing plate with described oven door body, makes the free gluing, sealing of oven door body to body of heater mouth for applying free force to oven door body.
Further, described Flexible Connector is fiber block.
Further, described bearing connection comprises bearing, connecting axle and bearing, described bearing settlement is in described fire door installing plate and be arranged in described oven door body, and described connecting axle is arranged on described bearing, and described bearing to be arranged on described connecting axle and to be connected with described oven door body.
Further, described bearing is radial bearing.
Further, described connecting axle is also provided with bearing spacer, 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 A are arranged, and described angle A is 60 ~ 90 °.
Further, lift cylinder for promoting oven door body is also comprised 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, multiple oven door body is connected by Flexible Connector, compared to prior art, prevents fire door Yin Wendu too high and produces distortion, good sealing effect, avoid stove gate to produce runout, reduce the loss of energy, thus reduce production cost; Oven door body is installed on fire door installing plate by bearing connection, automatically can regulate the laminating degree of oven door body and body of heater opening, avoid the damage of stove gate ironcasting and sealing strip, extend the service life of ironcasting and sealing strip.
