Pig house trench ventilation system
Technical Field
The utility model belongs to the automatic extensive breed technique especially involves the livestock farm structure of extensive breed.
Background
At present, large-scale culture technology is more and more popular, the culture cost can be obviously reduced, and the benefit can be improved, but the large-scale culture can cause the problems of pollution of the atmosphere and the water body. For example, toxic and harmful gases, dust, pathogenic microorganisms and the like generated by a farm can be diffused and spread along with the atmosphere after being discharged into the atmosphere. When these substances are discharged in amounts exceeding the tolerance of the atmospheric environment (self-cleaning ability), they are harmful to humans and animals. According to the test, a 10-million pig farm which is slaughtered in one year can discharge nearly 148 kg of ammonia (NH3), 13.5 kg of hydrogen sulfide (H2S), 24 kg of dust and 14 hundred million of thalli to the atmosphere every hour, the pollution radius of the substances can reach 5 kilometers, and the dust and disease microorganisms can spread for more than 30 kilometers along with wind. To avoid this problem, it is necessary to use active ventilation techniques for the farm, i.e. active air circulation using an exhaust fan system.
In the conventional single-span large-scale pigsty trench ventilation system, a fan is generally arranged at one end of a trench, and the air duct of the large-scale pigsty is usually longer and is more than 30 meters. The design mode that sets up the fan in trench one end can't make the head end and the end of whole full-length wind channel accomplish to ventilate unanimously evenly, it is obvious to be close to fan side ventilation effect usually, and keep away from fan side ventilation effect and be more and more poor even no air flow phenomenon, just so can not in time effectual outside the house of discharging through the trench ventilation system and rise to above the ground in the excrement ditch that leads to partial position, lead to the interior air quality of pig house poor, do not really reach the purpose of trench ventilation, arouse some diseases to take place easily.
SUMMERY OF THE UTILITY MODEL
Because the fan side ventilation effect is kept away from to partial irrigation canals and ditches among the solution prior art is more and more poor even no air flow phenomenon, just so lead to harmful gas in the excrement ditch at partial position can not in time effectually discharge the house through trench ventilation system and rise to above ground, lead to the air quality poor in the pig house, do not really reach the purpose of trench ventilation, arouse the technical problem that some diseases take place easily, the utility model provides a pig house trench ventilation system can improve ventilation efficiency.
In order to achieve the purpose, the utility model adopts the following technical scheme.
A pigsty trench ventilation system comprises a dung trench under the ground of a pigsty and a ventilation channel in the dung trench, wherein the dung trench is covered by a dung leaking plate with an opening, the bottom of the dung trench is a dung trench bottom plate, the ventilation channel is covered by an upper cover plate without an opening, the bottom of the ventilation channel is also the dung trench bottom plate, and the dung trench and the ventilation channel are separated by a side wall;
a plurality of rectangular ventilation holes are formed at the junction of the side wall and the upper cover plate, the height of the plurality of rectangular ventilation holes is smaller than that of the side wall, and the bottom edges of the rectangular ventilation holes do not reach the dung ditch bottom plate;
