Description
Technical field
The invention belongs to the technical fields of door, specifically disclose a kind of automatic safety door.
Background technology
Various inflammable and explosive articles are arrived currently, can be used in many Workshop Productions, fire are easy to happen, in order in fire
Sanctuary is provided to shop worker when calamity occurs, safety door is equipped in workshop, is safety cage or office after safety door.Peace
Air cock can effectively delay fire behavior sprawling when fire occurs, and race against time for rescue, but existing safety door is due to being pure
Pure solid door, fire resisting duration are limited.In order to be effectively prevented in the safety cage after flame enters safety door, also for
The fire resisting duration of enhancing safety door, the thickness of safety door is generally large, so its weight is especially heavy, some safety doors
Weight causes very much it to have to be mounted in wall again, and the flameproof effect of these safety doors is preferable.But what scene of fire occurred
In casualty situations, there is substantial portion of casualty to be not due to thermal-flame lethal, but because high-temperature flue gas enters
It is scalded after person's windpipe, injures and deaths of suffocating, present safety door lacks the function of flue gas mostly.
Invention content
The purpose of the present invention is to provide a kind of automatic safety doors, and cigarette can not be effectively prevented to solve existing safety door
The problem of gas.
In order to achieve the above object, base case of the invention is：Automatic safety door, including doorframe, the doorframe setting
On wall, the doorframe is equipped with the first door body, and the width of the doorframe is more than the width of the first door body, and the first door body is set
The side close to safety cage on doorframe is set, the upper end of doorframe is equipped with opening, and opening is sealed using sealing strip, and the sealing strip is adopted
It is made of kirsite, first chamber, first chamber and open communication is equipped in the wall, second is equipped in the first chamber
Door body, second door body include several inner door panels arranged successively along the width direction of doorframe, intermediate door-plate and several outer
Side door plate, the inner door panel, intermediate door-plate and the length of outside door-plate and the length of doorframe are identical, inner door panel, outer door
The height of plate is gradually increased along the direction far from inner door panel, in the inner door panel close to the upper end of the side wall of safety cage, in
Between door-plate two side upper end and outside door-plate on the upper end of side wall far from safety cage be equipped with the first limited block, it is described
Close to the side wall lower ends of safety cage and first chamber on the lower end of side wall, outside door-plate in inner door panel far from safety cage
Two side bottom is equipped with the second limited block, the first limited block and the length of the second limited block and the length of doorframe is identical, described
Several powdered sodium carbonates are placed with above intermediate door-plate；The second chamber for containing dilute hydrochloric acid is additionally provided in the wall,
Second chamber is located at the top of first chamber, and the bottom of second chamber is equipped with first through hole, and first through hole is connected to first chamber,
The bottom of first through hole is equipped with plunger, and the bottom of plunger is equipped with drawstring, and the bottom of drawstring and the top of intermediate door-plate are affixed.
The operation principle of this base case is：When fire occurs, scene temperature is minimum all at 400 degree or so, kirsite
Fusing point substantially also at 400 degree or so, so fire occur after sealing strip can be by high temperature melt.After sealing strip melts, inner door
Plate, outside door-plate and intermediate door-plate can immediately fall off and separate safety cage and the external world.Intermediate door-plate can drive drawstring when falling
It moves down, stretching will pull out plunger, and the dilute hydrochloric acid in second chamber will fall and be contacted with powdered sodium carbonate at this time
The reaction product of reaction, the two has water and carbon dioxide, carbon dioxide to be full of the pressure that can make first chamber after first chamber
Become larger, extraneous flue gas cannot be introduced into.
The advantageous effect of this base case is：
1. safety door weight in the prior art is big, it is not easy to push, it is all very laborious when opening and closing, in the present solution, the
One door body uses in normal operation in normal production, and when use is simple and convenient, and the second door body is automatic after fire occurs
It falls, the opening and closing of the first door body will not usually be had an impact.
2. the safety door that can be fallen exists in the prior art, but the height of these safety doors necessarily is greater than the height of doorframe
Degree, since the weight of safety door is big, so very inconvenient when attaching it to above doorframe.In the present solution, the second door body includes
Inner door panel, outside door-plate and intermediate door-plate, the height of three differs, and after fire occurs, three falls and stacked on top, phase
The limited block of the upper and lower of adjacent two inner door panels or outside door-plate offsets successively, ultimately forms complete second door body, institute
With when fire not occurring, the second door height is relatively low, will not occupy too many space, be easily installed.After fire occurs, flue gas
Temperature it is higher, can float up, and the shape of the second door body is up big and down small, so the fire resistance above it is more preferable, more
Conducive to preventing flue gas.
3. the main reason in the prior art, the flue gas performance of safety door is low is poor sealing at its gap.We
In case, after fire occurs, dilute hydrochloric acid and sodium carbonate can react generation carbon dioxide, make to fill in the first chamber above the second door body
Denounce great amount of carbon dioxide, internal pressure is high, so extraneous flue gas cannot be introduced into, while the gap in this programme is mostly adjacent
Between two limited blocks, and the gap at this is just in the first chamber, so most gaps are all blocked.If there is
Gap sealing performance it is bad, carbon dioxide can spray from the gap, play the role of certain fire extinguishing, while carbon dioxide sprays
Also neighbouring flue gas can be driven to flow outward after going out, flue gas is broken up.
4. the thermal coefficient of carbon dioxide is relatively low in gas, so its heat transfer property is poor, it is high that blocking can be played
The effect of temperature.Dilute hydrochloric acid and sodium carbonate can also react generation water, and water also has certain cooling effect.5. dilute hydrochloric acid and sodium carbonate
Reaction belong to the endothermic reaction, reaction is to absorb amount of heat, can also play the cooling effect to the second door body.
Further, the outside door-plate is equipped with several second through-holes, and one end of the second through-hole is located at the top of outside door-plate
The other end in portion, the second through-hole is located on the door-plate of outside on the side wall far from safety cage.When the carbon dioxide mistake in first chamber
After mostly, in pressure increase, but the stability of pressure too the second door body of conference pair has an adverse effect.In the present solution, two
Carbonoxide can actively be released from the second through-hole, and extraneous flue gas is dispelled.
Further, it is equipped with pressure valve in second through-hole.Using this programme, the only pressure in first chamber reaches
After pressure valve preset value, pressure valve can just be opened.
Further, it is equipped on the outer wall of the inner wall of the doorframe, the outer wall of the first limited block and the second limited block close
Sealing, the sealant are made of elastic sealant.The sealing performance of the second door body can be enhanced using this programme.
Further, one of inner door panel and one of outside door-plate connect with the second limited block screw thread of its bottom
It connects.Using this programme, after fire behavior is brought under control, limited block is removed from inner door panel and outside door-plate using tool, this
When underlying inner door panel and outside door-plate will fall to the ground, convenient for the indoor personnel's disengaging of safety.
