Abstract
The invention provides a novel induced draft machine. The novel induced draft machine comprises a machine body, a motor and an induced draft fan connected with the motor. A protection pad is arranged at the connection part between the motor and the induced draft fan. A shockproof layer is arranged in the machine body, and the distance between the shockproof layer in the machine body and an impeller of the induced draft fan is increased to be 0.5 time the length of the impeller. An air inlet is formed in the lower part of the machine body, and an air outlet is formed in the left part of the machine body. The motor and the machine body are connected through nuts. A dust screen is arranged on the air inlet. According to the novel induced draft machine, the distance between the machine body and the induced draft fan is increased, so that friction between the air and a metal shell is reduced; the shockproof layer is arranged, so that the noise is lowered accordingly; the volume of an air cavity is increased, so that the flow of induced air of the induced draft fan is increased, the efficiency is improved, and the energy is saved.
Description
Technical field
The invention belongs to technical field of chemical production equipment, especially relate to a kind of Novel induced draft fan.
Background technique
Induced draught fan of the prior art when in use, along with the increase of air inducing power, its produce noise pollution also constantly increase, have even up to 60-80 decibel, have a strong impact on working environment.Namely allow to produce more powerful induced draught fan, if do not reach national environmental standard to the control of noise pollution, 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, namely the air of 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 and friction in rotation simultaneously is also the source of noise.
Therefore the key that noise becomes the air inducing efficiency increasing induced draught fan how is reduced.
Summary of the invention
The object of this invention is to provide a kind of structure simple, easy to operate, induced draught fan can be cut down and collide produced vibration and friction mutually with hardware in body, reduce the Novel induced draft fan of noise when induced draught fan works.
Technological scheme of the present invention is: provide a kind of Novel induced draft fan, it is characterized in that: comprise body, motor and the air inducing that is connected with motor is fanned, described motor and described air inducing fan between joint be provided with protection pad; Described internal body is provided with shakeproof layer; Distance between the impeller that the shakeproof layer of described internal body and described air inducing are fanned 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 air inlet 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.
The advantage that the present invention has and good effect are: owing to adopting technique scheme, be provided with shakeproof layer in its body, and which increase body and air inducing fan between toe from, 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, namely improves efficiency, reaches the advantages such as energy-conservation object again.

Embodiment
Below in conjunction with accompanying drawing 1 and embodiment, the invention will be further described.
The invention provides a kind of Novel induced draft fan, it is characterized in that comprising body 4, motor 9 and the air inducing that is connected with motor 9 fans 2, described motor 9 and the described air inducing joint of fanning between 2 are provided with protection pad 1; Described body 4 inside is provided with shakeproof layer 3; Distance between the impeller that 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 works, it makes the friction between air and metal shell reduce, 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 place is provided with Air Filter 5, can stop dust, make body cleaner.
The impeller of described air inducing fan 2 is equipped with tilt angle to a certain degree, and its angle of inclination is approximately 45 °.
Described intake grill 6 is screw type with described exhaust outlet 8, and it can reduce air circulation resistance.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
