Description

technical field

[0001] The invention relates to the technical field of furnace top sealing devices, in particular to a gas sealing device. Background technique

[0002] At present, on the top of the blast furnace, the sealing cover is often squeezed and deformed, resulting in poor sealing of the top of the blast furnace, making it impossible for the blast furnace to achieve high top pressure. Therefore the defect existing in the prior art becomes a technical problem urgently to be solved by those skilled in the art. Contents of the invention

[0003] In view of the above-mentioned defects in the prior art, the purpose of the present invention is to propose a roof sealing device which is simple in structure, easy to use, and suitable for blast furnace roof with large discharge.

[0004] The purpose of the present invention will be achieved through the following technical solutions: a furnace top sealing device, including a sealing cover, characterized in that: a pressure p...

Embodiment Construction

[0010] A furnace roof sealing device provided in this embodiment is suitable for blast furnace roof large discharge. Four bolts 3 and four nuts 4 matched therewith are arranged, and the height of these bolts and nuts can be adjusted up and down. At the same time, the pressing plate is connected with the sealing cover through a pin shaft 5 .

[0011] In the present invention, the sealing cover is squeezed by adjusting the height of the bolt and the nut, so that the sealing cover is slightly deformed, and the sealing performance of the sealing cover is significantly improved. The furnace top pressure can be increased by installing the furnace top sealing device, and the comprehensive benefit of blast furnace production can be improved. The design has remarkable effect, strong practicability, improved operation efficiency, simple structure, easy operation and low production cost.
