Abstract
The invention relates to a high-temperature-resistant axial flow ventilator for a ship. The high-temperature-resistant axial flow ventilator for the ship comprises an air inlet section, a middle section, a motor, an impeller and an air outlet section. The air inlet section or the middle section is evenly provided with a plurality of motor air inlet pipes arranged in the radial direction. The motor is sleeved with a motor shell, the motor shell is supported in the middle section through a plurality of motor air outlet pipes which are evenly distributed on the periphery of the motor shell and arranged in the radial direction, and the front and rear ends of the motor shell are connected with the motor air inlet pipes and the motor air outlet pipes respectively. Any end of the motor is connected with a fan in a penetrating mode. The motor is reserved inside the motor shell and externally provided with a heat insulation cover, the motor is provided with a fan for cooling, air is fed from the motor air inlet pipes to cool the motor and then discharged from the motor air outlet pipes without affecting the performance of the ventilator, the environment temperature of the motor keeps at the normal temperature all the time, the operation reliability and safety of the motor are guaranteed, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of axial-flow blower, is a kind of high temperature resistant propeller fan peculiar to vessel specifically.
Background technique
Along with developing rapidly of China's ship industry, increasing modernization high-tech, high-caliber equipment investment will be had in shipping transport.Fire-fighting smoke exhaust system on ship is for guaranteeing when starting fire-fighting system, the a large amount of high-temperature flue gas produced can be discharged to out of my cabin effectively in time, improve compartment environment, usual employing propeller fan smoke evacuation, traditional axial-flow blower connects impeller by the motor straight be arranged in Fan casing, motor for a long time high temperature, flue gas, add ocean is moist, salinity is high environment under work, easily aging, burn into damages, and working life is short.
Summary of the invention
For above-mentioned deficiency of the prior art, the invention provides a kind of structure simple, compact, use stable, motor security of operation, reliable, the peculiar to vessel high temperature resistant propeller fan increased the service life can be guaranteed.
The technical solution used in the present invention is: a kind of high temperature resistant propeller fan peculiar to vessel, comprise wind inlet section, intermediate section, motor, impeller and wind outlet section, it is characterized in that: described wind inlet section or intermediate section are evenly equipped with multiple motor air intake pipe radially arranged, motor outer has motor casing, motor casing is supported in intermediate section through the multiple motor air outlet tubes radially arranged around its circumference uniform distribution, the front and back ends of motor casing connects motor air intake pipe and motor air outlet tube respectively, and any one end cross-under of motor has fan.
Further, the rear end that described motor stretches out motor casing connects the impeller be arranged in intermediate section or wind outlet section.
Further, the inner side of described motor casing and/or motor air intake pipe and/or motor air outlet tube and/or outside are provided with thermal shield.
Again further, described thermal shield is that sound-insulating and heat-insulating is cotton.
Adopt said structure, motor is retained in motor casing inside, additional thermal shield, motor carries fan cooled, while the performance not affecting blower fan, discharged by motor air outlet tube by after motor air intake pipe air intake cooling motor, the ambient temperature of motor remains at normal temperature, running reliability of motor and Security secure, increase the service life.To there is wind inlet section and the motor air intake pipe of diffusion action or integrate with thermal shield, namely ensure that motor does not bear high temperature, increase blower pressure again.Blower fan air outlet tube possesses the effect of coaxial support motor casing simultaneously, guarantees that the safety and stability of motor in blower fan supports.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: wind inlet section 1, intermediate section 2, wind outlet section 3, motor 4, impeller 5, motor air intake pipe 6, motor casing 7, motor air outlet tube 8, fan 9, thermal shield 10.
Embodiment
Be described further below in conjunction with drawings and Examples.
Shown in Fig. 1: a kind of high temperature resistant propeller fan peculiar to vessel comprises wind inlet section 1, intermediate section 2, wind outlet section 3, motor 4, impeller 5, motor air intake pipe 6, motor casing 7, motor air outlet tube 8, fan 9 and thermal shield 10.Wind inlet section 1, intermediate section 2 is connected successively with wind outlet section 3, wind inlet section 1 shrinks diffusion structure forward in horn-like, wind inlet section 1 be circumferentially evenly equipped with multiple motor air intake pipe 6 radially arranged, motor air intake pipe 6 connects motor casing 7 front end be coaxially arranged in intermediate section 2, motor 4 is arranged in motor casing 7, motor 4 front end connects fan 9, motor casing 7 is supported in intermediate section 2 through the multiple motor air outlet tubes 8 radially arranged around its circumference uniform distribution, the rear end that motor 4 stretches out motor casing 7 connects the impeller 5 be arranged in wind outlet section 3, motor air intake pipe 6, motor casing 7 and motor air outlet tube 8 are coated with thermal shield 10.
Above-described embodiment is that the one of technical solution of the present invention is simply implemented, and establishes motor casing in every employing blower fan, by into and out of airduct to the improvement of the motor cooling in motor casing, protection all in type protection domain of the present invention.
Claims (4)
