Description

Technical Field

[0001] The utility model relates to the field of ventilation, in particular to a fresh air ventilation device for a piggery. Background Art

[0002] Pig farming is a common breeding industry. Pigs are raised in pig houses. Due to the large number of pigs raised in pig houses, odors spread in the air, causing the air in the pig houses to be turbid. Usually, ventilation devices are installed in pig houses. The operation of the ventilation devices is used to suck out the turbid air inside the pig houses, so that the air and odors are discharged to the outside of the pig houses, and the external air is transported into the pig houses to ensure the cleanliness and circulation of the air in the pig houses.

[0003] The fresh air ventilation device usually consists of an exhaust device and an air intake device. The exhaust device is used to exhaust the air in the pig house. Common exhaust devices mostly use exhaust fans to draw the air in the pig house. The odorous air flows through the inside of the exhaust device and then is discharged from one end outside the exhaust device. The air containing the odor is directly discharged into the outside air, causing the odor to float outside the pig house. In addition, the air inside the pig house contains bacteria. Direct discharge can easily cause the spread of bacteria and pollute the environment. Utility Model Content
