Description

Technical Field

[0001] The utility model belongs to the technical field of breeding environment control equipment, in particular to a disease-proof livestock and poultry house without small windows which adopts micro-positive pressure ventilation. Background Art

[0002] Technical background: At present, negative pressure ventilation is used in both domestic and international breeding industries. The simple principle is to exhaust air through the fan at the end of the livestock and poultry house, causing the air pressure in the house to decrease. Due to the change in the air pressure difference between the inside and outside, the outside air passively enters the chicken house. The air enters the chicken house mostly through small side wall windows, and there are also small roof windows, gable windows or side wall ducts. Traditional small window ventilation breeding houses use single-building methods, which have requirements on the width of the chicken house.

[0003] In the current negative pressure ventilation mode, outside air enters the chicken house directly without being treated. The environment inside the house changes dramatically and is greatly affected by external climate changes. At the same time, pathogenic microorganisms are transmitted by the air, causing the spread of diseases, which puts great pressure on prevention and control.

[0004] At present, some livestock and poultry houses use positive pressure air supply + high-efficiency filtration ventilation, which has high investment cost, high operating costs and poor disease prevention effect. Utility Model Content
