Abstract
The utility model provides a novel induced draft fan. The novel induced draft fan comprises an engine body, a motor and an induced draft fan connected with the motor, wherein a protection pad is arranged at the connecting part between the motor and the induced draft fan, an anti-vibration layer is arranged inside the engine body, a distance between the anti-vibration layer inside the engine body and an impeller of the induced draft fan is increased to be 0.5 time of length of the impeller, an air inlet is formed below the engine body, an air outlet is formed in the left side of the engine body, the motor is connected with the engine body by a nut, and a dust gauze is arranged at the air inlet. According to the novel induced draft fan, the distance between the engine body and the induced draft fan is increased, so that the friction between air and a metal shell is reduced; the anti-vibration layer is arranged, and the noise is reduced accordingly; the induced air flow rate of the induced draft fan is increased due to increase of the volume of an air chamber, that is, the efficiency is improved and the advantages of energy saving and the like are achieved.
Description
Technical field
The utility model belongs to chemical production equipment technical field, especially relates to a kind of Novel induced draft fan.
Background technique
When in use, along with the increase of air inducing power, the noise pollution of its generation also constantly increases induced draught fan of the prior art, have even up to 60-80 decibel, have a strong impact on working environment.Allow to produce more powerful induced draught fan, if the control of noise pollution is not reached to national environmental standard, also cannot be come into operation.The noise of induced draught fan is mainly derived from the rotation of fan on induced draught fan and produces vibrations, the air that is High Rotation Speed collides produced vibration and friction mutually with the hardware in induced draught fan, cause the resonance of ventilation duct and fan, the machinery of High Rotation Speed unstable generation mechanical vibration in rotation are simultaneously also the sources of noise with friction.
Therefore how to reduce the key that noise becomes the air inducing efficiency that increases induced draught fan.
Model utility content
The purpose of this utility model is to provide a kind of simple in structure, easy to operate, can subdue induced draught fan and collide mutually produced vibration and friction, the Novel induced draft fan of the noise while reducing induced draught fan work with the interior hardware of body.
The technical solution of the utility model is: a kind of Novel induced draft fan is provided, it is characterized in that: the air inducing fan that comprises body, motor and be connected with motor, and the joint between described motor and described air inducing fan is provided with protection pad; Described internal body is provided with shakeproof layer; Distance between the impeller of the shakeproof layer of described internal body and described air inducing fan is increased to 0.5 times of impeller length; The below of described body is provided with intake grill; The left of described body is provided with exhaust outlet; Described motor is connected by nut with described body; Described intake grill place is provided with Air Filter.
The impeller of described air inducing fan is equipped with tilt angle to a certain degree, and angle of inclination is about 45 °.
Described intake grill and described exhaust outlet are screw type.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, in its body, be provided with shakeproof layer, and it has increased the distance between body and air inducing fan, the friction between air and metal shell is reduced, and being provided with shakeproof layer, noise also declines thereupon.The increase of wind cavity volume also makes the draught flow rate of induced draught fan increase simultaneously, has improved efficiency, reaches again the advantages such as energy-conservation object.

Embodiment
Below in conjunction with accompanying drawing 1 and embodiment, the utility model is described in further detail.
The utility model provides a kind of Novel induced draft fan, the air inducing fan 2 that it is characterized in that comprising body 4, motor 9 and be connected with motor 9, and the joint between described motor 9 and described air inducing fan 2 is provided with protection pad 1; Described body 4 inside are provided with shakeproof layer 3; Distance between the impeller of the shakeproof layer 3 of described body 4 inside and described air inducing fan 2 is increased to 0.5 times of impeller length, and when induced draught fan is worked, it reduces the friction between air and metal shell, and is provided with shakeproof layer, and noise also declines thereupon.The below of described body 4 is provided with intake grill 6; The left of described body is provided with exhaust outlet 8; Described motor 9 is connected by nut 7 with described body 4; Described intake grill 6 places are provided with Air Filter 5, can stop dust, make body cleaner.
The ，Qi angle of inclination, tilt angle that the impeller of described air inducing fan 2 is equipped with is to a certain degree approximately 45 °.
Described intake grill 6 and described exhaust outlet 8 are screw type, and it can reduce circulation of air resistance.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
