Technical Field

[0001] The present invention relates to the technical field of livestock breeding, and specifically to a livestock building with positive pressure air filtration and centralized exhaust for all seasons and its method. Background Art

[0002] A livestock building refers to a building specifically used for raising livestock. It needs to meet the biological characteristics and sanitary requirements of livestock, providing a good living environment for livestock to ensure their health and productivity. In order to keep the air in the room fresh, cool and oxygen-rich, and effectively discharge the bad air caused by high temperature, stuffiness, waste gas and dirty gas in the room, a wind box is usually set up to discharge the turbid odor generated due to poor ventilation, reduce air pollution, and thus improve the air quality in the livestock building.

[0003] Currently, most livestock buildings or building complexes adopt the negative pressure ventilation mode, which circulates and extracts the air in the building through a negative pressure fan. Since there is an air leakage problem easily existing at the gaps in the livestock building or building complex under the negative pressure ventilation mode, and the unfiltered air will pose a potential hazard to the health of livestock. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a livestock building with positive pressure air filtration and centralized exhaust for all seasons and its method. This livestock building adopts the positive pressure ventilation method to send fresh air into the compartments.

A plurality of compartments arranged side by side are spaced apart in each floor of the main body of the livestock building; a ventilation duct passing through all the compartments on each floor is installed at the top of each floor of the main body of the livestock building;

[0007] An integrated air supply box located at the front end of the main body of the livestock building is installed at the air inlet end of the ventilation duct. A positive pressure fan for blowing fresh air into the ventilation duct is installed in the integrated air supply box. Air inlet windows connected to each compartment are opened at the bottom of all the ventilation ducts;

[0008] A building air shaft covering the entire main body of the livestock building is provided at the rear end of the main body of the livestock building. Air outlet windows connected to the building air shaft are opened in each floor of the main body of the livestock building. The air outlet end of the building air shaft is arranged on the roof of the main body of the livestock building.

[0009] Adopting the above scheme, this livestock building adopts the positive pressure ventilation method to send fresh air into the compartments. Compared with the traditional negative pressure ventilation mode, it avoids the inflow of unfiltered air into the compartments, greatly reducing the probability of livestock getting sick.
