Abstract
The utility model provides a blowing-suction type anti-smoke air curtain device which is a jetting device generating air curtains, and is composed of a blower, a blowing and smoke discharging pipeline connected with the blower and an air blowing and sucking port communicated with the blowing and smoke discharging pipeline, wherein the other end of the blowing and smoke discharging pipeline is a closed end, the air blowing and sucking port is connected with the side wall of the blowing and smoke discharging pipeline, and the centerline of the air blowing and sucking port is a horizontal direction and is perpendicular to the shaft line of the blowing and smoke discharging pipeline. The utility model is mainly installed in a building elevator or a passage of a front room of a stairs, and the generated air curtains can effectively prevent smoke from diffusing to an evacuating passage so as to ensure the personal safe evacuation and furthest reduce personal casualty.
Description
Technical field
The utility model relates to a kind of structural fire protection safety device, particularly relates to a kind of blowing and drawing type smoke-preventing air curtain device.
Background technology
Fire is the fire phenomena very serious to mankind harm, and causing death's factor is a lot of in the fire, and wherein, deadly number accounts for about 80% of whole death tolls owing to suck harmful smoke, prevents from therefore that flue gas from spreading to have very important significance.Chinese patent 012731552 discloses a kind of skyscraper smoke-preventing air curtain, and it is mounted in the air curtain fluidic device at skyscraper elevator or stair cup passage place, is made up of motor, impeller and shell.Shell is a cover body, and its upper end is provided with air inlet, and the lower end is provided with the gas outlet, and impeller is made up of the roller and the strip arc shaped blade at two ends.Though this device is provided with the efflux angle of certain angle, does not have fume extractor, there is certain leakage cigarette amount in actual use, therefore can not play complete effect every cigarette.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of energy shape the gentle air curtain that becomes second nature, the blowing and drawing type smoke-preventing air curtain device of effectively anti-leak-stopping cigarette.
The utility model blowing and drawing type smoke-preventing air curtain device is achieved in that its blower fan, the air-supply smoke discharging pipe that is connected with blower fan, and the pressure-vaccum gas port that communicates with the air-supply smoke discharging pipe is formed.The pressure-vaccum gas port is provided with installing hole, the pressure-vaccum gas port is connected the other end sealing of air-supply smoke discharging pipe, the center line of pressure-vaccum gas port and the axis normal of supply and exhaust pipe by fixture with the air-supply smoke discharging pipe.The center line of pressure-vaccum gas port is a horizontal direction.For regulating air output or exhaust smoke level, can in the pressure-vaccum gas port, bearing plate be set, and the dividing plate that can slide is set in vertical direction on bearing plate, the push-and-pull hole is set on the dividing plate, with handled easily, pass through the effective area size of air-flow by the slidable adjustment pressure-vaccum gas port of dividing plate, thereby reach the purpose of regulating air output or exhaust air rate as the case may be.
The operation principle of the utility model blowing and drawing type smoke-preventing air curtain device is, the both sides at elevator or stair cup passage during use are installed two these devices simultaneously accordingly, and wherein one as air-supply usefulness, and another is used as smoke evacuation.The blower fan of stream oriented device is selected the rightabout rotation, when the blower fan of left-hand unit is air-supply, the pressure air that is produced enters the pressure-vaccum gas port through the air-supply smoke discharging pipe, and discharge from the pressure-vaccum gas port, on passage, form air curtain, the pressure air that right-hand unit is sent left-hand unit (may be mingled with a small amount of flue gas) sucks from the pressure-vaccum gas port, discharges through air-supply smoke discharging pipe and blower fan.Form at interchannel flexible every the smoke background barrier, thereby safety evacuation when guaranteeing that fire takes place.
The advantage of the utility model blowing and drawing type smoke-preventing air curtain device is simple in structure, can effectively prevent smoke spillage, and forming does not influence the visual field flexible the barrier every smoke background, does not form obstacle, guarantees that flue gas does not enter the place of safety, reduces casualties to greatest extent.Be used for the security against fire protection in the building.

The specific embodiment
The utility model blowing and drawing type smoke-preventing air curtain device blower fan 1 be connected with blower fan 1 and the air-supply smoke discharging pipe 2 of other end sealing, and the pressure-vaccum gas port 3 that communicates with air-supply smoke discharging pipe 2 is formed.Wherein, pressure-vaccum gas port 3 is provided with installing hole 4, send the axis normal of the center line and the supply and exhaust pipe 2 of pressure-vaccum gas port 3.The center line of pressure-vaccum gas port 3 is a horizontal direction.Bearing plate 5 is set in the pressure-vaccum gas port 3, and in vertical direction the dividing plate 6 that can slide is set on bearing plate 5, dividing plate 6 is provided with push-and-pull hole 7.
Claims (3)
1, a kind of blowing and drawing type smoke-preventing air curtain device comprises the fluidic device that produces air curtain, it is characterized in that it by blower fan, the air-supply smoke discharging pipe that is connected with blower fan, and the pressure-vaccum gas port that communicates with the air-supply smoke discharging pipe is formed.
2, blowing and drawing type smoke-preventing air curtain device as claimed in claim 1, the other end sealing of the smoke discharging pipe that it is characterized in that blowing, the pressure-vaccum gas port is connected with the sidewall of supply and exhaust pipe, its center line be horizontal direction and with the axis normal of supply and exhaust pipe.
