(iv) farm manure removal system design

1, manure removal system process design

barn design based on clear Decal mode process design isolation 隔 舍 舍Flat-type scraping mode

pig manure tramped through the drain plate slit through the drain plate, freely falling into the trench, the squeegee machine timing starts to scrape the pig manure water out of the outdoor manifunction, through the siphon suction The manner flows into the outdoor manure ditch, which flows to the sewage treatment pool. The rear-binding breeds pregnant home boar house childbirth home delivery house, the incubation of the pig manure is less, avoiding epidemic problems in the maniferus between the units, liquid suspenders

(5) Circuit control system design

1, design basis

In summer, hot weather, arrange the fan, water curtain cooling, pig house indoor temperature must control the comfort of pigs, ventilation uses longitudinal large ventilation mode, generating air-cooled effects through high wind speed, reducing pigmentation temperature. In winter, cold weather, configure the ceiling windows and the ditch fan, the fan ventilation, the pig house is higher than the minimum breathing amount of the pig. Spring and autumn winter ventilation is gentle and changed, and the ventilation mode is smooth, and there is no stress to the pig.
Model is built by energy conservation, “pigs production hot + wall passing outdoor heat + roof delivery outdoor heat – ventilation Take heat – water curtain with heat – indoor water vapor evaporation Take heat = indoor heat”, indoor heat Control determines the change in indoor temperature. Reduce temperature is achieved by increasing the heat insulation performance of building materials.

Each pig house is hot in the hot and longitudinal ventilation mode, open the water curtain and fan, from the water curtain In the wind, the mountain fan exhaust gas, the use of water curtain evaporation and air cooling effects to achieve ventilation cooling; in winter low temperature, vertical ventilation mode is used, open the sky into the windows and some mountain wall fan dungers, turn off the water curtain into the air. It is only a minimum ventilation demand for pigs, and avoids cold stress and heat loss. In the spring and autumn season, the vertical / lateral + vertical ventilation mode is used. According to the exterior climate temperature changes, the transition ventilation mode is gently transitioned, and the air outlets are gradually switched between the sky into the wind and the water curtain.

Poster Summer vertical ventilation

Considering the high temperature and high humid climate in the south and central parts, the summer delivery house is vertical ventilation; the water curtain is opened in summer; the fresh air is cooling; the winter is closed, the fresh air enter the roof, winter fresh air is entered by the ceiling window , The polish is taken away by the fan. The occupation is ventilated in summer, and the other seasons are consistent with the delivery house.
