Abstract
The utility model discloses a civil heat and humidity resistant induced draft fan which comprises a umbrella type rain cover 1, an installation base 5, a support bracket 2, a drive motor 3, a motor bracket 4, a blade component 6 and a motor shaft 8. Wherein the installation base 5, the support bracket 2 and the motor bracket 4 are cast into a whole. The utility model is characterized in that an insulation board 7 with a shaft hole in its middle is added between the blade component 6 and the motor. The length of the motor shaft between the insulation board 7 and the blade component 6 is 4.5 cm or above. The installation base 5 is a rectangular or square base with an air channel through hole in its middle. The utility model has the easy installation and the good closure, and further improves the smoke exhaust effect and increases the smoke outlet space; when the induced draft fan isn't used, the smoke isn't obstructed and the smoke outlet is also smooth. The installation height of the motor is increased in order to reduce the invasion of the high humidity airflow for the motor and the humidity and be very conducive to the motor capacitance, which ensures that the motor can be used for a long time.
Description
Technical field:
The utility model belongs to induced draught fan, the induced draught fan that specifically civilian small oven or boiler are used.
Background technique:
Existing induced draught fan is often bad in using, and changes a plurality of motors within one month, through discovering that there are a lot of problems in the induced draught fan that dispatches from the factory now:
The induced draught fan of market sale now, after installation, without induced draught fan the time, because the motor chassis is too near near fan, the smoke space is little, stifled cigarette occurs, and smoke is not smooth.Because motor is low, and is too near from thermal source, produce high temperature during induced draught fan work, motor is bad easily, and lubricant oil is withered, and bearing loses lubricating function, causes motor to burn out.Because motor is low excessively, near excessively, flue dust is excessive, produces to stop up, and can not dispel the heat, and causes motor not turn round.In winter during low temperature, make moist and cause motor, electric capacity to burn out because the coal combustion bavin produces steam.
Technological scheme:
The utility model purpose is to disclose a kind of civilian moisture resistance hot induced draught fan.Form by umbellate form rain cover 1, mounting base 5, supporting frame 2, drive motor 3, electric machine support 4, blade assembly 6, motor shaft 8.Mounting base 5 is cast into one with supporting frame 2, electric machine support 4.Drive motor 3 by bolt on electric machine support 4, drive motor 3 is positioned on the medial axis of supporting frame 2, motor shaft 8 lower ends are fixed with blade assembly 6, umbellate form rain cover 1 is above motor, be fixed in supporting frame 2 upper ends, it is characterized in that: the thermal baffle 7 in tape spool hole in the middle of between blade assembly 6 and motor, installing additional.
The utility model improves again, and described civilian moisture resistance induced draught fan is characterized in that: the motor shaft length between described thermal baffle 7 and the blade assembly 6 is at 4.5cm or more than the 4.5cm.Described mounting base 5 is middle rectangle or the square seat that has the air channel through hole.
Description of drawings
Fig. 1 is the utility model structural drawing.
Specific implementation:
Because chimney shape difference among the people, square, circular, rectangular are arranged, when being circle during the induced draught fan mounting base, bad installation on square rectangular chimney, bad sealing has reduced blower effect, so ad hoc square, rectangular induced draught fan base.Promptly install, seal eye well, further improved smoke discharging effect.For ` further improves the air draft performance, strengthened the smoke space, when not using induced draught fan, cigarette is not obstructed yet, and smoke is also unobstructed.
Motor improves after the setting height(from bottom), has alleviated motor and encroached on by the high humidity air-flow, has also alleviated humidity, and motor electric capacity is also had very big benefit.Ensure that motor can use for a long time, life-saving adds thermal baffle again, has both protected motor, electric capacity and bearing oil moist, has stopped the infringement to motor bearings of flue dust, steam again.
