Further, described exhaust fan includes air flue and the fan being arranged in air flue, the inlet end of described air flue and outlet side are respectively arranged with the first filter element and the second drainage screen, the second filter element it is provided with between described fan and the second drainage screen, it is positioned at the second filter element bottom in the outer part on described air flue and is communicated with ash bucket, described ash bucket includes ash tube road and connection ash can bottom ash tube road, and the internal diameter of described top, ash tube road and bottom is more than the internal diameter at middle part.
Further, the bottom of described ash bucket is provided with inclined-plane, and the relatively downside on inclined-plane is provided with discharge outlet.
Further, the outside of described air flue is additionally provided with sealing lid.
Further, described ash tube road is threadedly attached on described air flue, and described ash can is threadedly attached on described ash tube road.
Further, described ash bucket is rustless steel ash bucket, and the smoothness of described ash bucket inner surface is mirror ultrafinish.
Further, the lateral surface of described second filter element is additionally provided with bright finish glass fiber mesh.
Further, described first filter element is active carbon filter core.
Further, described second filter element is glass fibre filter element.
By such scheme, this utility model at least has the advantage that under normal circumstances, and one of them of two groups of aerators keeps duty, when a failure occurs, the aerator of closing fault, switches to another group aerator, can ensure that SPF chicken coop air filtration system is the most in running order；Exhaust duct is folded upward at, while ensureing exhaust effect, under being filtered by the foreign material in hen house by the first drainage screen, falling in blanking box, it is to avoid blocking exhaust duct；It addition, exhaust fan also can realize auxiliary row's wind action；Whole mechanism, rational in infrastructure, convenient and practical, malleation combine negative pressure filtration, system stability good, when supply air system fault quits work, also can maintain normal operating thus avoid dirt to enter in hen house.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing describe in detail as after.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of exhaust fan in this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
See Fig. 1 and Fig. 2, a kind of SPF chicken coop air filtration system of this utility model one preferred embodiment, including hen house 10, supply air system and exhaust system, supply air system includes blast pipe 11, be connected on blast pipe side by side two groups of aerators 12 and the air intake passage 13 being arranged on hen house ceiling and being connected with blast pipe 11, be provided with filter 14 at blast pipe 11 air inlet；Exhaust system includes being arranged on the air exhaust passage 15 of hen house corner, the exhaust duct 16 being connected on air exhaust passage and being folded upward at and being arranged on exhaust duct outlet side the exhaust fan 17 towards horizontal direction air draft, the bending place of exhaust duct 16 is provided with the first drainage screen 18, and the bottom of the first drainage screen 18 is provided with blanking box 19.
Operation principle of the present utility model is: under normal circumstances, one of them of two groups of aerators keeps duty, when a failure occurs, the aerator of closing fault, switch to another group aerator, can ensure that SPF chicken coop air filtration system is the most in running order；Exhaust duct is folded upward at, while ensureing exhaust effect, under being filtered by the foreign material in hen house by the first drainage screen, falling in blanking box, it is to avoid blocking exhaust duct；It addition, exhaust fan also can realize auxiliary row's wind action；Whole mechanism, rational in infrastructure, convenient and practical, malleation combine negative pressure filtration, system stability good, when supply air system fault quits work, also can maintain normal operating thus avoid dirt to enter in hen house.
SPF chicken coop air filtration system of the present utility model, exhaust fan 17 includes air flue 21 and the fan 22 being arranged in air flue, the inlet end of air flue 21 and outlet side are respectively arranged with the first filter element 23 and the second drainage screen 24, it is provided with the second filter element 25 between fan 22 and the second drainage screen 24, it is positioned at the second filter element 25 bottom in the outer part on air flue 21 and is communicated with ash bucket, ash bucket includes ash tube road 26 and connection ash can 27 bottom ash tube road, and the internal diameter of top, ash tube road 26 and bottom is more than the internal diameter at middle part.When the fan in air flue is properly functioning, the air within hen house through the first filter element filtering laggard enter fan air inlet, be expelled in air through the second filter element and drainage screen, now higher due to the air pressure in ash bucket, air essentially by gas outlet discharge；When fan breaks down or during the situation of power-off, outside air can be less than normal and reversely flow into due to the air pressure in hen house, bigger impurity is intercepted in outside by drainage screen, less impurity is intercepted by the second filter element, a part of impurity falls into ash can due to gravity by ash tube road, and a part rests on the second filter element, when fan recovers operating, stay the impurity on the second filter element to be taken out of by air-flow, drain in air.
In order to prevent rainwater from entering hen house, after rainwater is intercepted by the second filter element, falling into ash can, SPF chicken coop air filtration system of the present utility model, the bottom of ash bucket is provided with inclined-plane, and the relatively downside on inclined-plane is provided with discharge outlet 28, and rainwater flows out from discharge outlet；When needs clear away waste case, the outside of air flue is additionally provided with sealing lid 29, it is only necessary to lid top cover labyrinth, can be sprayed by the impurity in ash can by high pressure draught and discharge outlet.
Dismantling ash bucket for convenience, regularly replace or clear up, SPF chicken coop air filtration system of the present utility model, ash tube road is threadedly attached on air flue, and ash can is threadedly attached on ash tube road.
Falling in ash can for the ease of impurity, SPF chicken coop air filtration system of the present utility model, ash bucket is rustless steel ash bucket, and the smoothness of ash bucket inner surface is mirror ultrafinish.
For the ease of intercepting less impurity so that it is falling in ash bucket, SPF chicken coop air filtration system of the present utility model, the lateral surface of the second filter element 25 is additionally provided with bright finish glass fiber mesh.
SPF chicken coop air filtration system of the present utility model, the first filter element is active carbon filter core 23, and the second filter element 25 is glass fibre filter element.
The above is only preferred implementation of the present utility model; it is not limited to this utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
