Abstract
The utility model relates to a device capable of preventing smoke from coming down from a chimney of a coal-fired furnace. The device capable of preventing the smoke from coming down from the chimney of the coal-fired furnace is composed of a smoke inlet, a bearing, a bearing fixing ring, a wind guide plate, a chimney elbow and a smoke outlet. The device capable of preventing the smoke from coming down from the chimney of the coal-fired furnace is characterized in that the smoke inlet is fixedly connected with the bearing, the bearing is fixedly connected with the bearing fixing ring which is fixedly connected with the chimney elbow, and the wind guide plate is arranged on the chimney elbow. Under the effect of wind, the wind guide plate can drive the bearing to rotate, the chimney elbow is enabled to rotate towards the leeward direction, and the smoke outlet is enabled to be in a leeward state; and under the downwind action outside the chimney elbow, smoke or coal gas in the chimney can come out of the chimney smoothly and be blown away. The device capable of preventing the smoke from coming down from the chimney of the coal-fired furnace has the advantages of being simple in structure, low in manufacturing cost and capable of effectively preventing the smoke or the coal gas in the chimney from coming down and entering a room.
Description
Technical field
The utility model relates to a kind of smoke-backflow-proof device, relates in particular to a kind of coal furnace chimney device of falling the cigarette that prevents.
Background technology
Winter is in the northern area of China, still there are a lot of families to use small coal furnace to warm oneself, most of small coal furnace does not take to prevent the device of coal gas suck-back, face outdoor strong wind weather, under the wind-force effect, cigarette or coal gas can pour in down a chimney from outlet flue and enters indoorly, and gas poisoning occurs, and can threaten people's life when serious.
Summary of the invention
For addressing the above problem, the utility model provides a kind of coal furnace chimney device of falling the cigarette that prevents, is achieved through the following technical solutions:
A kind of coal furnace chimney device of falling the cigarette that prevents, consist of by advancing mouth, bearing, bearing race snap, wind deflector, chimney elbow, outlet flue, it is characterized in that: advance mouth and be fixedly connected with bearing, bearing is fixedly connected with bearing race snap, bearing race snap is fixedly connected with the chimney elbow, and the chimney elbow is provided with wind deflector.
The beneficial effects of the utility model are: simple in structure, cost is low, can effectively avoid cigarette in the chimney or coal gas to pour in down a chimney entering indoor.
Description of drawings
Fig. 1 is the utility model schematic diagram
Wherein, 1-advances mouth, 2-bearing, 3-bearing race snap, 4-wind deflector, 5-chimney elbow, 6-outlet flue.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.As shown in Figure 1, a kind of coal furnace chimney device of falling the cigarette that prevents, consist of by advancing mouth 1, bearing 2, bearing race snap 3, wind deflector 4, chimney elbow 5, outlet flue 6, it is characterized in that: advance mouth 1 and be fixedly connected with bearing 2, bearing 2 is fixedly connected with bearing race snap 3, bearing race snap 3 is fixedly connected with chimney elbow 5, and chimney elbow 5 is provided with wind deflector 4.Wherein wind deflector 4 is under the wind-force effect, can be with dynamic bearing 2 to rotate, so that chimney elbow 5 is towards leeward direction rotation, make outlet flue 6 be in leeward mouthful, add the with the wind effect of chimney elbow 5 outsides, cigarette or unimpeded the emerging of coal gas in the chimney dispel, and avoid cigarette or coal gas to pour in down a chimney entering indoor, eliminate gas poisoning hidden danger.
