Abstract
The utility model provides a high pressure and low noise ventilator for tunnels, relating to an axial flow fan used for the ventilation of the tunnel construction or other underground engineering. A casing is a cylindrical silencer formed by a hole plate and noise dampening material; the casing is correspondingly provided with two impellers respectively driven by two motors, wherein, the two impellers have equal wheel diameter but opposite steering; a silencer for a suction section and a silencer for an exhausting section are respectively arranged on the center of the suction section and the exhausting section in the casing, forming the annular channel of the ventilator together with the casing. The utility model has the advantages of high pressure, low noise, double-stage running, single-stage running, aeration with the positive rotation and draught with the reverse rotation.
Description
The utility model relates to a kind of axial flow tunnel fan that is used for tunnel construction or the ventilation of other underground engineering.
Tunnel fan of the prior art mostly is the single-stage axial blower fan, and it mainly is made of housing, motor and impeller.Housing is a cylindrical shape, and its suction end is a horn mouth; Impeller is installed in central authorities in the housing by motor driving and together with motor.This single-stage axial ventilator is owing to have only an impeller, and do not adopt any noise elimination noise abatement measure, so its pressure is low, flow is little and noise is big, can not satisfy the requirement of modern mechanical underground construction far away.Often modernized construction plant can not be played one's part to the full, also make air dirt in the tunnel, serious harm workmen's health simultaneously because air output is not enough.
The purpose of this utility model is the big and little axial flow tunnel fan of noise of design a kind of pressure height, flow, to satisfy the needs of modern mechanical underground construction.
To achieve these goals, the utility model is designed to the ventilator housing cylinder type silencing apparatus that is made of orifice plate and muffler material, and in housing air-breathing section and exhaust section central authorities install one air-breathing section silencing apparatus and exhaust section silencing apparatus respectively, thereby constitute the ring runner of ventilator and significantly reduce the noise level of ventilator.Meanwhile, in housing, install two relatively respectively by two motor-driven impellers, thereby constitute a kind of couple-stage axial-flow fans, to improve the pressure and the flow of blower fan.Following structure specific embodiment is described in further detail the technical characteristics of the utility model high pressure low noise tunnel fan.
Accompanying drawing 1 is the structural representation of the utility model high pressure low noise tunnel fan.
With reference to the accompanying drawings 1, the utility model high pressure low noise tunnel fan still is made of housing, motor and impeller.Housing 1 is the cylinder type silencing apparatus that is made of orifice plate and muffler material, and its suction end 2 is a horn mouth.Two impeller 5 and impellers 6 that driven by motor 3 and motor 4 respectively are housed in the housing 1 relatively, the external diameter that the wheel of impeller 5 and impeller 6 directly equates its root footpath and motor 3 and motor 4 about equally, the dead in line of its axis and housing 1 but switched in opposite, two impeller root spacings equal the 3-5% of impeller diameter.Air-breathing section central authorities are equipped with air-breathing section silencing apparatus 7 of a cylinder type and constitute the ring runner of ventilator with housing 1 in the housing; The suction end of air-breathing section silencing apparatus 7 is similar to hemisphere, and the external diameter of its external diameter and motor 3 about equally.The central authorities of exhaust section are equipped with a cone type exhaust section silencing apparatus 8 and constitute the ring runner of ventilator with housing 1 in the housing 1; The external diameter of exhaust section silencing apparatus 8 close motor 4 one ends and motor 4 external diameters are about equally.
The utility model pressure height, flow is big, noise is low; Both can move by twin-stage, also can single-stage move; Both rotary drum wind just, also reverse air inducing.Therefore, the utility model can be widely used in the construction ventilation of railway tunnel, vcehicular tunnel, seepage tunnel and other large-scale underground engineering.
