Humidification flame retardant fire door

Abstract

The invention provides a humidified flame-retardant fireproof door, which comprises a door body, a flame-retardant filling layer, surface barrier layers, a liquid storage tank, water outlets, workingcavities, pipe bodies, limiting layers, sealing blocks, sealing strips, a connecting rod, a movable rod, a rotating wheel, a spring, a liquid separation tank, a liquid collecting opening, a gauze layer and a liquid outlet groove. The flame-retardant filling layer is embedded in the door body; the surface barrier layers are tightly attached to the front end and the rear end of the door body; the liquid storage tank is opened in the top of the door body; water outlets are formed in the left lower corner and the right lower corner of the liquid storage tank; working cavities are fixedly formed inthe left side and the right side of the liquid storage tank; pipe bodies are embedded in the outer sides of the working cavities; limiting layers are tightly attached to the outer sides of the innerwalls of the pipe bodies; sealing blocks are movably connected into the limiting layers; and sealing strips are tightly attached to the outer sides of the sealing blocks. During actual use, the surface of the fireproof door can be cooled in all directions, so that the fireproof door cannot be burnt out by flames, the flame retardant effect is better, and the practicability of the device is enhanced.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a humidification flame retardant fire door. Background technique [0002] Fire doors are used to protect the fire escape from the spread of fire within a certain period of time when a fire occurs, to provide escape time for escapees as much as possible, and to win rescue time for firefighters. Usually, fire doors are covered with flame retardants on the surface Made of wood or steel materials, the interior usually uses fire-proof and heat-insulating materials to slow down the temperature rise of the fire-resistant door, so that the fire-resistant door can withstand a fierce fire for a long time before being burned. In the case of fierce and difficult to extinguish, the temperature of ordinary fire doors will rise rapidly, and it is difficult to buy a long time for the escapees. [0003] After patent retrieval, the existing patent number is CN201810037477.5 The invention discl...

Problems solved by technology

[0005] The purpose of the present invention is to provide a humidified flame retardant fire door to solve the problem that the surface temperature of the fire door will be high when the existing fire door is in contact with the flame for a long time, and the surface of the fire door cannot be cooled, and the flame retardant The effect is poor, and there are certain limitations in actual use
