Abstract
The utility model relates to a furnace top sealing device which comprises a sealing cover. The furnace top sealing device is characterized in that a pressing plate is arranged above the sealing cover; a fastener which can be vertically adjusted is arranged above the pressing plate; and the pressing plate is connected with the sealing cover by a pin roll. According to the furnace top sealing device disclosed by the utility model, the sealing cover is extruded by adjusting the heights of bolts and nuts, so that the sealing cover generates micro deformation and more remarkable effect for the sealing property of the sealing cover is realized. The pressure of the furnace top can be improved and comprehensive benefits of a blast furnace are increased by mounting the sealing device. The furnace top sealing device has the advantages of remarkable effect, strong practicality, increased operation efficiency, simple structure, simplicity and convenience in operation and low production cost.
Description
Technical field
The utility model relates to the technical field of oven roof sealing device, is specifically related to a kind of device to air seal.
Background technology
Diffuse greatly at blast furnace roof at present, sealing cover is out of shape owing to often being squeezed, and causes the stopping property of furnace roof relatively poor, makes blast furnace can't realize high pressure on top surface.Therefore the defective that exists in the prior art becomes those skilled in the art's technical problem anxious to be resolved.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the purpose of this utility model is that proposition is a kind of simple in structure, easy to use, is applicable to the oven roof sealing device that blast furnace roof diffuses greatly.
The purpose of this utility model, to be achieved by the following technical programs: a kind of oven roof sealing device, comprise sealing cover, it is characterized in that: described sealing cover top is provided with pressing plate, but described pressing plate top is provided with the fastening piece of up-down adjustment, and described pressing plate is connected by bearing pin with sealing cover.
The technical scheme that the utility model further limits is: described fastening piece is symmetrically set in described pressing plate top.
Further, aforesaid oven roof sealing device, described fastening piece are bolt and the nut that matches each other.
The utility model, its outstanding effect is: thus the utility model so that sealing cover produces micro-deformation, makes the stopping property of sealing cover produce more significant effect by the height Squeezing sealing lid of adjusting bolt and nut.Can improve the pressure of furnace roof by this oven roof sealing device is installed, and improve the comprehensive benefit that blast furnace is produced.The design's effect is remarkable, practical, has improved operating efficiency, and simple in structure, and is easy and simple to handle, and production cost is low.
Following constipation closes the embodiment accompanying drawing, embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of oven roof sealing device that the present embodiment provides, being applicable to blast furnace roof diffuses greatly, structure as shown in the figure, comprise a sealing cover 1, wherein, above the sealing lid, be provided with a block pressur plate 2, four nuts 4 that the pressing plate top is arranged with four bolts 3 and matches with it, but this bolt and nut height up and down.Simultaneously, pressing plate is connected by a bearing pin 5 with sealing cover.
Thereby the utility model is by the height Squeezing sealing lid of adjusting bolt and nut, so that sealing cover produces micro-deformation, makes the stopping property of sealing cover produce more significant effect.Can improve the pressure of furnace roof by this oven roof sealing device is installed, and improve the comprehensive benefit that blast furnace is produced.The design's effect is remarkable, practical, has improved operating efficiency, and simple in structure, and is easy and simple to handle, and production cost is low.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
