Abstract
Disclosed is a natural division type exhaust device, which comprises an exhast duct. A hood is arranged at the top of the exhast duct. An air inlet is arranged on the exhast duct. An exhaust spacer is arranged on the position in the exhast duct corresponding to each air inlet, whose the upper edge is higher than the air inlet. The exhaust spacer is an integrated folded plate of which a vertical face is fixedly sealed on the inner wall of the exhast duct. The lower edge of an inclined plane of the folded plate is fixedly sealed in the side wall of the exhast duct under an air outlet. As the exhaust spacer is arranged in the exhast duct, another exhaust system is formed to take action with the original exhast duct at the same time, thus keeping the negative pressure in the exhast duct steady and removing the phenomenon of smoking and flowback.
Description
Technical field
The utility model belongs to a kind of natural flow-guiding type air exhausting device, relates in particular to the anti-smoke blowing of nature flow-guiding type and pours in down a chimney air exhausting device.
Background technology
The main effect of chimney is the cigarette that puts a chimney on the stove and make the fire draw, and drains flue gas, improves burning condition.Adopt oil expulsion channel among the highrise building, use smoke exhaust ventilator to force air draft, because exhast duct straight up and down at present, each air intake place does not have reasonably to prevent and treat the facility that smoke blowing is poured in down a chimney, cause lower floor's smoke evacuation easily, the phenomenon that pour in down a chimney on the upper strata, cause unnecessary trouble for the personnel of different floors, so the use of exhast duct is not really general, but the advantage of use exhast duct but clearly, be exactly that smoke blowing among the highrise building pours in down a chimney be a stubborn problem, how exhast duct being improved, allow its better service among modern high-rise building, is a thing of benefiting the nation and the people.
The utility model content
The purpose of this utility model provides the natural flow-guiding type air exhausting device that a kind of control smoke blowing simple in structure, that cost is low is poured in down a chimney.
In order to achieve the above object by the following technical solutions: comprise exhast duct, the exhast duct top is provided with blast cap, exhast duct is provided with air intake, position corresponding with each air intake in exhast duct is provided with the air draft dividing plate, the upper edge of air draft dividing plate is higher than air intake, described air draft dividing plate is the flap of one, and flap vertical plane sealing and fixing is on the exhast duct inwall, on the exhast duct sidewall of the lower edge sealing and fixing on flap inclined plane below air intake.
The angle on described flap vertical plane and inclined plane is 120 °.
Do not link to each other mutually between two upper and lower adjacent air draft dividing plates.
The cross section of described exhast duct is a rectangle.
The utility model is provided with the air draft dividing plate in exhast duct, formed another exhaust system, acts on simultaneously with original exhast duct, keeps stable negative pressure, the phenomenon of having eliminated smoke blowing and having poured in down a chimney in exhast duct.All being provided with the air draft dividing plate in the air intake of each floor prevents between the floor smoke blowing and pours in down a chimney.And the utility model is simple in structure, cost is low, air draft is stable, and is applied widely and can play good result.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
As shown in drawings, a kind of natural flow-guiding type air exhausting device, comprise exhast duct 1, the cross section of exhast duct 1 is a rectangle, the exhast duct top is provided with blast cap 4, exhast duct is provided with some air intakes 3, position corresponding with each air intake 3 in exhast duct 1 is provided with air draft dividing plate 2, the upper edge of air draft dividing plate is higher than air intake 3, described air draft dividing plate is the flap of one, and flap vertical plane sealing and fixing is on the exhast duct inwall, on the exhast duct sidewall of the lower edge sealing and fixing on flap inclined plane below air intake, the angle on flap vertical plane and inclined plane is 120 °, on two, do not link to each other mutually between the adjacent down air draft dividing plate.
