Abstract
The utility model discloses a device for inducing air to aid combustion and discharging indoor foul air simultaneously when coal is combusted in the coal stove, and especially discloses an air inducing and pollution discharging device for a coal stove. The air inducing and pollution discharging device for a coal stove is characterized in that it comprises a centrifugal blower which is arranged at a chimney hole on the outer wall of a room, the air outlet of the centrifugal blower is provided with a jet pipe, the periphery of the jet pipe is provided with a casing, the casing is connected with an inhaling chimney and a discharging chimney, and the nozzle of the jet pipe is positioned in the discharging chimney. The air inducing and pollution discharging device possesses a simple structure, and is reliable in work; the wind wheel of the air inducing device does not inhale high temperature flue gas directly, thus overheating is prevented and manufacturing cost is low; and indoor foul air can be discharged, and the air inducing and pollution discharging device is economic and affordable.
Description
(1) technical field
The utility model relates to a kind of combustion-supporting device of discharging indoor foul atmosphere simultaneously of coal stove when burning air inducing, particularly a kind of coal stove air inducing blowdown machine of being used for.
(2) background technology
The air-introduced machine of known present prior art, its operation principle are the runner rotations, produce kinetic energy and directly suck gas and air inducing.Be used for coal stove burning combustion-supporting because of the coal stove flue-gas temperature very high, rotor shaft can be overheated, the bearing of air-introduced machine and motor shaft all will adopt solar heat protection and falling temperature technique cost higher, because of increasing power consumption, the friction of solar heat protection seal-moving part also increases, and do not possess the function of getting rid of indoor foul atmosphere, so known air-introduced machine can not satisfy the economic and practical condition of household coal stove for heating.The household coal stove for heating adopts gravity-flow ventilation more at present, because of the chimney orientation not to or the chimney down draught takes place because of Changes in weather, gas poisoning happens occasionally in the resident family, promptly be under the normal condition, in the room of burning coal stove also is the air dirt, feel downer hope foul atmosphere can be discharged outdoor, if will produce negative pressure with exhaust fan is then indoor, the coal stove chimney is wanted down draught, does not still have the equipment of economic and practical definite assurance safety and sanitation at present.
(3) summary of the invention
The utility model is in order to remedy the defective of prior art, and a kind of coal stove air inducing blowdown machine of economic and practical, safety and sanitation is provided.
The utility model is achieved by the following technical solution:
A kind of coal stove air inducing blowdown machine, it is characterized in that: comprise the centrifugal blower that is installed on the external wall of house chimney hole, the air outlet place of centrifugal blower is equipped with playpipe, and the playpipe outer periphery has casing, be connected with on the casing and suck chimney and discharge chimney, the nozzle of playpipe is positioned at discharges chimney.
This coal stove air inducing blowdown machine if coal stove is the layout near exterior wall, then sucks chimney and discharges the perpendicular both sides that are installed in casing of chimney, and playpipe is a straight tube; If coal stove is the layout away from exterior wall, then suck chimney and discharge the symmetrical both sides that are installed in casing of chimney, playpipe is a bend pipe.This coal stove air inducing blowdown machine is designed according to jet current principle, rotate and the suction medium air by the centrifugal blower wind wheel, high-speed gas via the nozzle ejection that is located at playpipe produces the low pressure suction area, the flue gas that sucks coal stove is taken out of outdoor by high-speed gas, because wind wheel does not directly suck high-temperature flue gas, so rotor shaft can be not overheated.
The beneficial effects of the utility model are: this coal stove air inducing blowdown machine, and simple in structure, reliable operation, the wind wheel of air-introduced machine does not directly suck high-temperature flue gas, thereby can be overheated not cheap for manufacturing cost, and the dirty gas in the room can be discharged, and is economic and practical.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the schematic diagram of the utility model coal stove air inducing blowdown machine bend pipe structure.
Accompanying drawing 2 is the schematic diagram of the utility model coal stove air inducing blowdown machine straight tube structure.
Among the figure, 1 playpipe, 2 casings, 3 centrifugal blowers, 4 suck chimney, and 5 discharge chimney.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This coal stove air inducing blowdown machine, it is characterized in that: comprise the centrifugal blower 3 that is installed on the external wall of house chimney hole, the air outlet place of centrifugal blower 3 is equipped with playpipe 1, playpipe 1 outer periphery has casing 2, be connected with on the casing 2 and suck chimney 4 and discharge chimney 5, the nozzle of playpipe 1 is positioned at discharges chimney 5.Suck chimney 4 and discharge the chimney 5 perpendicular both sides that are installed in casing 2, playpipe 1 is a straight tube; Suck chimney 4 and discharge the chimney 5 symmetrical both sides that are installed in casing 2, playpipe 1 is a bend pipe.
This coal stove air inducing blowdown machine, adopt centrifugal blower 3 as power, during work, suck air from centrifugal blower 3 air inlets and be sent to playpipe 1 as the jet working media, the gas that sprays at a high speed according to fluid mechanics principle forms the suction area of low pressure in the casing 2 near playpipe 1 nozzle, suction area is brought the flue gas that coal stove burning back is produced into discharge chimney 5 by sucking chimney 4, medium gas and gas smoke mix in discharging chimney 5, convert big portion kinetic energy to pressure and can discharge beyond the room wall.Because centrifugal blower 3 is residing external than higher, indoor foul atmosphere also is aloft, so what centrifugal blower 3 air inlets sucked also is indoor foul atmosphere, be used as after these foul atmospheres suck jet media be discharged to outdoor, thereby play dirt eliminating function.
