Abstract
The invention relates to a furnace top sealing device, which includes a sealing cover. The device is characterized in that a press plate is arranged above the sealing cover, vertically adjustable fasteners are arranged on the press plate, and the press plate and the sealing cover are connected via a pin shaft. According to the invention, heights of the bolts and the nuts are adjusted to press the sealing cover, so that the sealing cover is subjected to small deformation, to achieve a remarkable sealing effect of the sealing cover. The blast furnace top pressure can be improved by installing the inventive furnace top sealing device and the comprehensive benefits of blast furnace production is also improved. The furnace top sealing device has the advantages of remarkable design effect, strong practicability, high working efficiency, simple structure, convenient operation and low production cost.
Description
Technical field
The present invention relates to the technical field of boiler roof sealing device, be specifically related to a kind of device air seal.
Background technology
On the blast furnace furnace roof diffused greatly, sealing cover was out of shape owing to often being squeezed at present, caused the stopping property of furnace roof relatively poor, made blast furnace can't realize high roof pressure power.Therefore the defective that exists in the prior art becomes those skilled in the art's technical problem anxious to be solved.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the objective of the invention is to propose a kind of simple in structure, easy to use, be applicable to the boiler roof sealing device that the blast furnace furnace roof diffuses greatly.
The object of the invention; To be achieved through following technical scheme: a kind of boiler roof sealing device, comprise sealing cover, it is characterized in that: said sealing cover top is provided with pressing plate; But said pressing plate top is provided with the fastening piece of up-down adjustment, and said pressing plate is connected through bearing pin with sealing cover.
The technical scheme that the present invention further limits is: said fastening piece is symmetrically set in said pressing plate top.
Further, aforesaid boiler roof sealing device, said fastening piece are bolt and the nut that matches each other.
The present invention, its outstanding effect is: thus the present invention is through regulating the height Squeezing sealing lid of bolt and nut, makes sealing cover produce micro-deformation, makes the stopping property of sealing cover produce significant effect.Through the pressure that this boiler roof sealing device can improve furnace roof 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, and specific embodiments of the invention is done further to detail, so that technical scheme of the present invention is easier to understand, grasp.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
A kind of boiler roof sealing device that present embodiment provides; Be applicable to that the blast furnace furnace roof diffuses greatly, structure is as shown in the figure, comprises 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 through a bearing pin 5 with sealing cover.
Thereby the present invention is through regulating the height Squeezing sealing lid of bolt and nut, makes sealing cover produce micro-deformation, makes the stopping property of sealing cover produce significant effect.Through the pressure that this boiler roof sealing device can improve furnace roof 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.
Except that the foregoing description, the present invention 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 requirement of the present invention.
