Fireproofing device of ventilating duct for conveying high greasy dirt/high powder dust fluids

Abstract

The invention relates to a refractory protection used for conveying high oil stain / high dust fluid ventilation pipeline. The refractory protection is characterized by comprising a folding vane mechanism (1), a guideway (2), and a telescopic mechanism (3) which is fixed in the guideway (2); the upper end (11) of the folding vane mechanism (1) is fixedly connected with the top end of the guideway (2); the lower end of the folding vane mechanism (1) is fixedly connected with the head of the telescopic mechanism (3); the folding vane mechanism (1) comprises a plurality of vanes which are connected with each other; a plurality of middle movable ends (13) are formed by vanes which are connected end to end; the tail end of the telescopic mechanism (3) is fixedly connected with the bottom end of the guideway (2); the telescopic mechanism (3) is internally provided with a temperature sensor (4); the signal output terminal of the temperature sensor (4) is connected with the control input terminal of the telescopic mechanism; the refractory protection can form a curtain typed fireproof valve, can ensure fireproof safety and save conveying energy dissipation when conveying high oil stain and high dust fluid ventilation pipeline, and can be applied to general ventilation pipelines simultaneously.

Description

technical field [0001] The invention relates to a fire prevention device for a ventilation pipeline for transporting high oil pollution / high dust fluid, which is suitable for the ventilation pipeline for transporting high oil pollution and high dust fluid with fire prevention requirements. The utility model belongs to the technical field of building fire protection facilities. Background technique [0002] At present, the measure of dividing fire compartments in buildings can effectively control the fire within a certain range in the event of a fire in a building, reduce fire losses, and at the same time provide favorable conditions for the safe evacuation of personnel and fire fighting. . Fire compartments can be divided into two categories according to the function of preventing fire from expanding and spreading beyond the fire compartment: one is the vertical fire compartment, which is used to prevent the vertical fire spread between floors of multi-storey or high-rise b...
