Abstract
The utility model discloses a powerful draught fan, which relates to an exhaust device, in particular to an exhaust device mounted on the chimney of a coal-fired furnace. The powerful draught fan comprises an upright cylindrical shell (9), fan blades (2), an electric motor (5) and an upper cover (7); wherein, the upper cover (7) is assembled upon the shell (1) through upper cover supports (6); the electric motor (5) is assembled at the axial center in the shell (1) through a fixing unit; the main shaft of the electric motor (5) faces downwards; and the fan blades (2) are assembled on the main shaft of the electric motor (5). The utility model resolves the following problems of the prior like products: the smoke-exhausting effect is poor; the prior like products need to occupy indoor space; and the utilization efficiency of energy resource is low.
Description
Technical field
The utility model relates to a kind of air exhausting device, particularly a kind of air exhausting device that is installed on the coal furnace chimney.
Technical background
Coal furnace all was the gravitation that relies on chimney to produce in the past, and air inducing is combustion-supporting.At calm weather, or overcast and rainy, stove will be not smooth because of smoke evacuation, and anti-cigarette phenomenon occurs, and this has not only polluted indoor air, and it is low efficiency of combustion also can to occur, even flame-out phenomenon.Chinese patent ZL01254738.7 discloses a kind of Forced discharge fan, and what this exhaust blower adopted is centrifugal impeller formula blower fan, and the blast pipe of blower fan and flue are pegged graft, and therefore in use have following shortcoming: one, air draft effect is poor; Two, need take the interior space; Three, energy utilization rate is lower.
The utility model content
The utility model main purpose is to provide a kind of powerful air-introduced machine, the utility model solved the smoke discharging effect that existing like product exists poor, need take the interior space and the low problem of efficiency of energy utilization.
Powerful air-introduced machine, it is characterized in that, comprise: the shell of the vertical cylindrical structure that is provided with, blade, motor and the loam cake of fan, loam cake is installed in the top of shell by last lid support, motor is installed axial centre place in the enclosure by fixture, the main shaft of motor is downward, and blade is installed on the main shaft of motor.
Powerful air-introduced machine of the present utility model, be installed in when in use chimney above, the lower end of shell is connected with outlet of chimney.
The utlity model has following advantage: one, this machine adopts the axial flow mode, has strengthened the discharge effect greatly.Two, owing to adopt the axial flow mode, Gu after shutting down, still can discharge voluntarily, the cold and hot pressure effect of dependence shutdown impeller has by force promptly produced the discharge effect from row, prevents that also the shortcoming of freezing from appearring in impeller in the winter time.Three, this machine outward appearance is reasonable, owing to adopt electric motor built-in, so outward appearance cannot see motor, makes chimney outward appearance nature, harmony. and four, energy-conservation, owing to adopt built-inly, energy loss is less, makes full use of resource.Five, this machine has increased service life, owing to be built-in, motor is not encroached on by wind and weather, admittedly improve service life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further.
See Fig. 1, the powerful air-introduced machine of present embodiment, comprise: the shell 1 of the vertical cylindrical structure that is provided with, blade 2, motor 5 and the loam cake 7 of fan, loam cake 7 is installed in the top of shell 1 by last lid support 6, motor 5 is installed in axial centre place in the shell 1 by fixture, the main shaft of motor 5 is downward, and blade 2 is installed on the main shaft of motor 5.Loam cake 7 is a beveled structure, and the periphery of loam cake 7 is greater than the upper port of shell 1.Fixture comprises support ring 3 and bracing frame 4, and support ring 3 is installed on the inwall of shell 1, and bracing frame 4 is connected between support ring 3 and the motor 5.The lower port place of shell 1 is oriented turn up along 1-1.
