Smoke exhaust device for fire engineering

Abstract

The invention belongs to the technical field of fire-fighting engineering, particularly relates to a smoke exhaust device for fire-fighting engineering, and aims to solve the problems that when a smoke exhaust pipeline is used for exhausting smoke, a large amount of soot can be remained in a flue, and when the soot in the flue needs to be removed, the flue needs to be detached, and the smoke exhaust device is troublesome. A mounting hole is formed in the fixing seat, a net cover is fixedly mounted on the inner wall of the bottom of the mounting hole, smoke can be preliminarily filtered through the net cover, dust in the smoke is prevented from entering a conical pipe, and therefore the smoke conveying efficiency can be improved, and the conical pipe is fixedly mounted at the top of the net cover; before the smoke is conveyed into the smoke exhaust pipeline, dust in the smoke can be filtered, so that the smoke exhaust pipeline can be prevented from containing the dust, the smoke exhaust pipeline does not need to be frequently disassembled and cleaned during long-term use, and good convenience is achieved.

Description

technical field [0001] The invention relates to the technical field of fire protection engineering, in particular to a smoke exhaust device for fire protection engineering. Background technique [0002] According to the announcement number: CN214318934U, a smoke exhaust device for fire protection engineering belongs to the technical field of smoke exhaust mechanisms. The smoke exhaust device for fire engineering includes a smoke exhaust component and a lifting component. The smoke exhaust assembly includes a wall, an induced draft fan, a smoke guide hood, a first smoke guide pipe, a second smoke guide pipe, a longitudinal smoke guide pipe, a fire damper, a smoke exhaust valve, a box, an intelligent switch, a battery, and a lifting ear. , the first smoke guide branch pipe, the second smoke guide branch pipe, the water pipe, the tap water pipe, the solenoid valve and the smoke alarm, the induced draft fan is fixed in the inner wall of the wall body, when in use, the smoke exh...

AI Technical Summary

Problems solved by technology

[0003] At present, when using the smoke exhaust pipe to exhaust smoke, a large amount of soot will remain in the flue, and the smoke exhaust pipe is generally closed and installed. When it is necessary to clean the flue, it is often necessary to disassemble the flue, which is more troublesome, so We propose a smoke exhaust device for fire engineering to solve the problems raised above
