Description
Technical field
The utility model is people's air defense apparatus field, more specifically, it relates to a kind of smoke filtration closed guard gate.
Background technology
Closed guard gate is that government mobilizes and organize the masses, takes anti-air strike, and measure of fighting calamities and providing relief implements rescue and mitigates disaster
Used door when the activity of harm.It is divided into protective door, airtight blast door, sealed door according to function.It can divide again according to structure
For Steel structure door, armored concrete door.Closed guard gate is also required to ensure within one section of reasonable time (being typically escape time), protect
The people to escape in escape route is from the threat of fire, including barrier dense smoke and heating power.Existing closed guard gate generally can only
Dense smoke and heating power are obstructed, but trapped person cannot be given from clean harmless air is filtered out.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of smoke filtration closed guard gate.
For realization the purpose of this utility model, the technical solution adopted in the utility model is：
A kind of smoke filtration closed guard gate, including door-plate, upper rail, lower railway and sealing strip；The door-plate is set as left and right
Symmetrical two；The contact position of described two door-plates is provided with sealing strip；It is both provided with ventilation opening on described two door-plates；Institute
It states and is provided with baffle outside ventilation opening, the baffle can be rotated around axis pin to ventilation opening, until being closed；The ventilation opening is set
It is equipped with filtrating equipment of flue gas, the filtrating equipment of flue gas includes air-inlet grille, air-introduced machine, filter chamber and air outlet；The air inlet
Grid is arranged in the outside of filtrating equipment of flue gas, and the air-introduced machine is connect with air-inlet grille, the bottom of the filter chamber and air-introduced machine
Portion connects, and the filter chamber includes pre-filter layer, activated carbon filter layer and organic exhaust gas adsorption layer；It is set at the air outlet port
It is equipped with one layer of filter fiber.
Preferably, the door-plate is steel construction, thickness 30cm.
Preferably, the door-plate is each provided with two sliding slots up and down.
Preferably, the sliding slot is concave.
Preferably, it is provided with pulley in the sliding slot.
Preferably, the diameter of the pulley is less than the width of sliding slot.
Preferably, the ventilation opening is rectangle.
Preferably, it is both provided with handle on two side door plate.
Compared with the existing technology, the application achieves following advantageous effect：
The upper and lower of closed guard gate is both provided with sliding slot, although therefore closed guard gate it is very heavy, remain able to compare easily
It is pushed；And the setting of two sliding slots can enable what closed guard gate stablized to be built in doorframe, will not tilt.
It is provided with ventilation opening on door-plate, ventilation can be opened when needing, baffle is provided with outside ventilation opening, when needing to close
When ventilation opening or closed guard gate are by impact wave impact, baffle can be rotated around axis pin to ventilation opening, until being closed, so be designed
It can ensure indoor security.
By the way that multiple layers of filters is arranged, can be greatly reduced in flue gas with the particle and pernicious gas in high efficiency filter air
Harmful substance, safe and harmless air source is provided for indoor crowd.
