Abstract
The utility model discloses a conveying fan, which belongs to the field of air supply devices and comprises an air draft motor and an air cavity, wherein the air cavity is provided with an air outlet pipe and an air inlet pipe, and the air cavity is driven by the air draft motor to convey air; the conveying fan is also provided with an air return pipeline, one end of the air return pipeline is connected with the air outlet, and the other end of the air return pipeline is connected with the air inlet. The conveying fan returns part of air to an air pipe, so that noise is reduced.
Description
Technical field
The utility model relates to blast device field, particularly relates to a kind of wind conveyer.
Background technique
Traditional wind conveyer, being the machine of conveying gas, take induced draft fan as power; Traditional wind conveyer, after carrying gas to go out, directly discharges, cause noise very big, extremely affect use by blower motor.
Model utility content
For solving the above problems, the utility model provides a kind of wind conveyer, and noise is little.
Technical solution adopted in the utility model is: a kind of wind conveyer, comprises exhausting motor and air cavity, and air cavity is provided with air outlet tube and Gas inlet tube, and air cavity is driven by exhausting motor and carries out conveying wind; This wind conveyer is also provided with return air duct, and return air duct one end connects exhaust outlet place, and the return air duct the other end connects into air port place.
In technique scheme, before the exhaust outlet of air cavity, be connected with muffling bucket, reduce noise.
In technique scheme, this kind of wind conveyer has two Gas inlet tubes; Two Gas inlet tubes are all provided with ball valve and control.
In technique scheme, return air duct is provided with electronic cut-off wind valve, to control return air.
In technique scheme, between Gas inlet tube and air cavity, be provided with inlet air bucket.
In technique scheme, be provided with Decompression valves between air cavity and inlet air bucket, accidents happened to prevent air cavity and the overvoltage of inlet air bucket.
The beneficial effects of the utility model are: this kind of wind conveyer, is also provided with return air duct, and return air duct one end connects exhaust outlet place, and the return air duct the other end connects into air port place, is transmitted back to as airduct by part wind, to reduce noise.
Accompanying drawing explanation
Fig. 1 is overall structure figure of the present utility model;
In figure, 1, exhausting motor; 2, air cavity; 21, Gas inlet tube; 22, air outlet tube; 23, ball valve; 3, return air duct; 31, electronic cut-off wind valve; 4, muffling bucket; 5, inlet air bucket; 6, Decompression valves.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 show schematically show a kind of wind conveyer according to a kind of mode of execution of the present utility model.
A kind of wind conveyer, comprise exhausting motor 1 and air cavity 2, air cavity 2 is provided with air outlet tube 22 and Gas inlet tube 21, and air cavity 2 is driven by exhausting motor 1 and carries out conveying wind; This wind conveyer is also provided with return air duct 3, return air duct 3 one end connects exhaust outlet place, return air duct 3 the other end connects into air port place, air outlet tube 22 and Gas inlet tube 21 are all a three-way pipe, return air duct 3 one end connects one of them mouth of pipe of air outlet tube 22, and return air duct 3 one end connects into one of them mouth of pipe of airduct 21.
Above-mentioned, be connected with muffling bucket 4 before the exhaust outlet of air cavity 2, muffling bucket 4 is cylindric, during muffling bucket 4 air-out, can alleviate wind-force, is temporarily stored in by wind in muffling bucket 4, then be exported by air outlet tube 22, reduces noise.
Above-mentioned, this kind of wind conveyer has two Gas inlet tubes, 21, two Gas inlet tubes 21 and is connected; Two Gas inlet tubes 21 are all provided with ball valve 23 and control; Two ball valves 23 coordinate switch, can control Gas inlet tube 21 and to work or two Gas inlet tubes 21 work, thus control air output.
Above-mentioned, return air duct 3 is provided with electronic cut-off wind valve 31, to control return air; Electronic cut-off wind valve 31 is made up of valve body, jam and electric cylinder, and jam is controlled to control to block in valve body by electric cylinder.
Above-mentioned, be provided with inlet air bucket 5 between Gas inlet tube 21 and air cavity 2, inlet air bucket 5 is cylindric, during from Gas inlet tube 21 inlet air, can enter into inlet air bucket 5, and exhausting motor 1 can be strengthened by suction air quantity.
Above-mentioned, be provided with Decompression valves 6 between air cavity 2 and inlet air bucket 5, accidents happened to prevent air cavity 2 and inlet air bucket 5 overvoltage.
Above embodiment is just to illustrate instead of restriction the utility model, therefore all equivalences done according to the method described in the utility model patent claim change or modify, and are included in the utility model patent claim.
