Abstract
A negative pressure exhaust system for a closed type hog house relates to the field of livestock breeding and comprises a hog house, wherein a plurality of swineries are distributed in the hog house by rows; defecation passages are arranged at the lower parts which the swineries correspond to; a passageway is arranged between every two adjacent rows of swineries; exhaust passages are arranged at the lower parts which the passageways correspond to; the defecation passages and the exhaust passages are closed; an inclined breather pipe for being communicated with each exhaust passage is arranged on the wall of each defecation passage; and an exhaust blower is arranged at the outer part of each exhaust passage, and is communicated with each exhaust passage through an exhaust pipe. The negative pressure exhaust system has better air exchanging effect, can exhaust harmful air in the hog house in time, and guarantees that the temperature in the hog house cannot be reduced to a large extent.
Description
Technical field
The utility model relates to the livestock-raising field, is specifically related to a kind of closed pig house negative pressure exhaust system.
Background technology
Pig house needs warming and is in the environment of a relative closure in the winter time, can make the pernicious gas in the pig house and swim in airborne bacterial content increases greatly, these pernicious gases and germ can cause the respiratory system of pig to come to harm and cause the decline of immunity, and the illness rate of pig is increased.The vented exhaust system of existing pig house mainly relies on window or other exhaust outlet on the pig house to carry out ventilation, but this method for exhausting need be opened more window or other exhaust outlet, if ventilation volume is big, need ventilation time longer, the temperature of pig house can significantly reduce.
The utility model content
In order to address the above problem, the utility model provides a kind of closed pig house negative pressure exhaust system, satisfies the ventilation demand of pig house, and ventilation effect is better.
For achieving the above object, the technical solution of the utility model is: closed pig house negative pressure exhaust system, comprise pig house, in a row be distributed with a plurality of swinerys in the pig house, the below of swinery correspondence is the defecation passage, be provided with the passageway between two adjacent row's swinerys, the below of passageway correspondence is provided with the exhaust passage, defecation passage and exhaust passage are two airtight spaces, the wall of defecation passage is provided with the breather pipe of the inclination that is communicated with the exhaust passage, the outside of exhaust passage is provided with exhaust blower, and exhaust blower is communicated with the exhaust passage by blast pipe.
The below of the oblique exhaust passage of described breather pipe.
The end face of described pig house is provided with air inlet.
Beneficial effect: the utility model has been established an exhaust passage below swinery, the exhaust passage communicates with the defecation passage, by the outside exhaust of the outside connected exhaust blower in exhaust passage, so just can in time gas harmful in the pig house be discharged pig house, and need not open too many ventilation equipment, can not make the interior temperature of pig house reduce too big.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Be labeled as among the figure: 1, pig house, 2, swinery, 3, the defecation passage, 4, the exhaust passage, 5, breather pipe, 6, exhaust blower, 7, blast pipe.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Closed pig house negative pressure exhaust system, comprise pig house 1, in a row be distributed with a plurality of swinerys 2 in the pig house 1, the below of swinery 2 correspondences is defecation passage 3, the ground of swinery 2 is lattice-shapeds, the ight soil of pig is directly fallen in the defecation passage 3 of its below, be provided with the passageway between two adjacent row's swinerys 2, the below of passageway correspondence is provided with exhaust passage 4, defecation passage 3 and exhaust passage 4 are two airtight spaces, the wall of defecation passage 3 is provided with the breather pipe 5 of the inclination that is communicated with exhaust passage 4, and the outside of exhaust passage 4 is provided with exhaust blower 6, and exhaust blower 6 is communicated with exhaust passage 4 by blast pipe 7.
The below of described breather pipe 5 oblique exhaust passages 4.
The end face of described pig house 1 is provided with air inlet, replenishes fresh air by air inlet in pig house 1 in the time of exhaust.
Claims (2)
1. closed pig house negative pressure exhaust system, comprise pig house (1), in a row be distributed with a plurality of swinerys (2) in the pig house (1), the below that swinery (2) is corresponding is defecation passage (3), it is characterized in that: be provided with the passageway between two adjacent row's swinerys (2), the below of passageway correspondence is provided with exhaust passage (4), defecation passage (3) and exhaust passage (4) are two airtight spaces, the wall of defecation passage (3) is provided with the breather pipe (5) of the inclination that is communicated with exhaust passage (4), the outside of exhaust passage (4) is provided with exhaust blower (6), and exhaust blower (6) is communicated with exhaust passage (4) by blast pipe (7).
