Abstract
The invention discloses an air filtering device for a feedlot, and the air filtering device comprises a full sealed filter and a prefiltering device which is capable of filtrating large-particle suspended matters, and the prefiltering device can be disassembled to be sealed and covered on the lateral surface at the backward position of the full sealed filter. The air filtering device stops the large-particle suspended matters and prevents the large-particle suspended matters from entering the full sealed filter to block the filter element, therefore, the service life of the full sealed filter is prolong effectively, and the usage cost of the air filtering device for the feedlot is reduced.
Description
Technical field
The present invention relates to a kind of filter for installation, especially a kind of feed lot air filter.
Background technology
The layout of existing feed lot be single to animal growth and feed this direction and develop; And the virus cleaning pattern in the feed lot is just continued to use regular disinfectant method, can cause presumable virus not cleaned out like this, and also presumable virus lays dormant is in the animal body; In order to address this problem; Occur at present carrying out filtration treatment to the air of feed lot, such feed lot by between roof interlayer 1, animal stable breeding 2, enclosure wall 3, ventilating fan 4 and air cleaner 5 etc. form, compare with common feed lot; It has increased air cleaner 5 and a ventilating fan 4 in wall and the roof; Above-mentioned used air cleaner 5 is hermetic, if filter is not hermetic or does not use filter that airborne virus can be attached on the airborne suspended particulate; Thereby get in the zoic environment, finally cause the generation and the propagation of disease.
In some large-scale commercial aquaculture bases; They use some pocket types or high efficiency particulate air filter prevents the spread of disease; But with bag filter, it can only move under specific air quantity, when indoor air temperature changes greatly; The rotating speed speed of blower fan differs when being variable air rate, and bag filter breaks easily.Though high efficiency particulate air filter can well filter out virus; But in this environment of feed lot, big and small suspended particulate is more, is easy to the filter core of blocking highly effective filter; Cause high efficiency particulate air filter to damage; Need often to change, and high efficiency particulate air filter is with high costs, high like this feeding cost makes the big sense of a lot of operators disappointed.
Summary of the invention
In order to overcome above-mentioned defective, the present invention provides a kind of feed lot air filter, and use cost was low when this feed lot air filter can effectively prevent viral invasion.
The present invention is in order to solve the technical scheme that its technical problem adopts: a kind of feed lot air filter; Comprise hermetically sealed filter and the preposition filter that can filter the bulky grain suspension; Preposition filter can be dismantled the sealing covering and be positioned at hermetically sealed filter downstream outer surface; Incidental suspended particulate all stops the bulky grain suspension get off through preposition filter earlier in the interior air of feed lot; It is interior with the filter core obstruction to prevent that effectively the bulky grain suspension from getting into hermetically sealed filter, has effectively prolonged the service life of hermetically sealed filter, has reduced the use cost of feed lot air filter.
As further improvement of the present invention, said preposition overanxious device is a filtering screen.
As further improvement of the present invention, said preposition overanxious device is a rough filter, and this kind filter cost is low, bulky grain suspended material good filtration effect.
As further improvement of the present invention, said hermetically sealed filter is a high efficiency particulate air filter.
As further improvement of the present invention, said hermetically sealed filter is the closed type medium effeciency filter, and its cost is low, good filtration effect.
The invention has the beneficial effects as follows: the present invention is employed in the structure that outer surfaces sealing in hermetically sealed filter downstream is provided with preposition filter bulky grain suspension in the feed lot is stopped to get off; Preventing that the bulky grain suspension from getting into stops up filter core in the hermetically sealed filter; Effectively prolong the service life of hermetically sealed filter, reduced the use cost of feed lot air filter unit.

The specific embodiment
Embodiment: a kind of feed lot air filter; Comprise hermetically sealed filter 6 and the preposition filter 7 that can filter the bulky grain suspension; Preposition filter 7 can be dismantled the sealing covering and be positioned at hermetically sealed filter 6 downstream outer surfaces; Incidental suspended particulate all stops the bulky grain suspension get off through preposition filter 7 earlier in the interior air of feed lot; Preventing effectively that the bulky grain suspension from getting in the hermetically sealed filter 6 stops up filter core, has effectively prolonged the service life of hermetically sealed filter 6, has reduced the use cost of feed lot air filter.
Said preposition overanxious device is a filtering screen.
Said preposition overanxious device is a rough filter, and its cost is low, bulky grain suspended material good filtration effect.
Said hermetically sealed filter 6 is a high efficiency particulate air filter.
Said hermetically sealed filter 6 is the closed type medium effeciency filter, and its cost is low, good filtration effect.
