Influence the mood of experimenter's operation experiments.Therefore, in order to be more favorable for the discharge of waste gas, laboratory would generally be provided with air draft and set
It is standby.In existing exhaust equipment, axial flow blower is generally fitted with, and axial flow blower is typically mounted in exhaust duct, during use
Between a length, easy adsorbent solid particulate matter on blade, once and blower interior damage, be unfavorable for service worker's detachable maintaining.
Utility model content
The utility model provides a kind of axial flow blower, and the axial flow blower has the advantages of easy to assemble, easy cleaning.
To achieve the above object, the utility model provides following technical scheme:
A kind of axial flow blower, including hollow cylindrical shell, the enclosure interior are provided with motor and rotated to carry
For the negative pressure fan of negative-pressure air power, the negative pressure fan is mutually fixed with motor output end, and the cylindrical shell both ends are all provided with
Have the first adpting flange, correspondingly, in addition to two with for the ventilation duct and fastener that are connected with cylindrical shell both ends,
The second adpting flange is respectively equipped with two ventilation ducts, the second adpting flange is consolidated with the first adpting flange by fastener
It is fixed；The cylindrical shell is provided with the filter for being used for solid particulate matter in air filtering perpendicular to central axis direction.Wherein, post
Shape housing both ends are provided with the first adpting flange, and ventilation duct is provided with the second flange detachably coordinated with the first adpting flange, makes
It is more convenient to obtain maintenance personal's maintenance process.Filter can filter out the solid particulate matter in gas simultaneously so that negative pressure wind
Fan is not easy to gather dust, so as to influence exhaust effect.
Preferably, the fastener includes screw bolt and nut, and correspondingly, first adpting flange and the second connection method
The screwed hole passed through for bolt is equipped with orchid.
Preferably, the negative pressure fan is angularly disposed in motor output end.Angularly disposed negative pressure fan institute
Caused wind direction more tends to axle center, and more concentrates, so that exhaust effect is more preferable.
Preferably, the filter includes screen pack, the screen pack is fastened transversely to inside cylindrical shell.
Preferably, the cylindrical shell inner transverse is provided with the fixing groove for accommodating fixed screen pack.
Preferably, the screen pack is arranged at the end opening of cylindrical shell side.
The beneficial effects of the utility model are：
In the utility model, cylindrical shell both ends are provided with the first adpting flange, and ventilation duct is provided with and the first connection method
The second flange that orchid detachably coordinates so that maintenance personal's maintenance process is more convenient.Filter can be by gas simultaneously
Solid particulate matter filters out so that negative pressure fan is not easy to gather dust, so as to influence exhaust effect.
