Ventilating method and device of animal colony house

Abstract

The invention discloses a ventilating method which makes a ventilation effect good, is suitable for dry and cold boreal climate conditions and is used for an animal colony house. The ventilating method is characterized in that the colony house comprises a roof installed on a high-side wall, supporting columns and a low-side wall, the roof is a slope surface, the included angle formed by the slopesurface and a horizontal plane is an acute angle of 5-15 degrees, outdoor fresh air enters the colony house through an air inlet mechanism arranged at the upper portion of one side of the high-side wall and flows towards the lower portion on one side of the low-side wall in the colony house from gradually from top to bottom, and waste air in the colony house is collected and centralizedly treatedby a pipeline-type air outlet mechanism arranged at the lower portion of one side of the low-side wall and then is discharged. Air in the colony house undergoes heating treatment through pipeline airinflow in winter, control is quick and convenient, the cost is low, operation control of workers is simple and easy, and the pipeline-type air outlet mechanism also facilitate centralized treatment and discharge of waste air in the colony house. In addition, air is guided to flow downward through air guiding pipe arranged on the supporting columns, so that fresh air in the colony house contains uniform oxygen, and temperatures at the front end and the rear end in the colony house are uniform.

Description

technical field [0001] The present invention relates to a livestock farm construction, in particular to a ventilation method and a ventilation device for animal pens, in particular to a ventilation method for animal pens with good ventilation effect and suitable for dry and cold northern climates and ventilation devices. Background technique [0002] In recent years, animal husbandry, such as pig and cattle breeding, has become increasingly large-scale and intensive, and has put forward higher requirements for the design and construction of animal pens. Among them, the ventilation of animal pens , Cooling and heat preservation are the important technical contents. Existing animal pens, such as pig houses, generally only have skylights on the upper part of the pig houses, through which air convection and ventilation can be performed. This pen structure can only achieve partial ventilation, and the cooling effect in summer is not obvious, and the heat preservation effect in w...

AI Technical Summary

Problems solved by technology

Although the pig house adopts the roof ventilation method in winter, the fresh air in the pig house still flows horizontally. There is also a dead angle of ventilation on the side of the tuyere, and the environment in the pig house is poor

Moreover, under the huge temperature difference in dry and cold areas, any slight opening of the large-area ventilation window will result in a huge area of ​​cold air intake, and it will not be possible to achieve effective tube bundle centralized heating treatment, resulting in a large heating cost and preheating heat loss from air

[0005] At the same time, the above two pig house structures are inconvenient to control the air inlet and outlet volume in winter, so they are not suitable for the dry and cold northern climate conditions.

In addition, the exhaust gas of the above-mentioned pens is discharged from the top or side of the pen to the air. First, it will bring discomfort to the people working in the pen; second, the exhaust gas will rise to the roof to corrode the roof; Dirty and harmful air such as air flows upwards in the house, making animals in an environment of breathing dirty air at any time, resulting in an increase in respiratory diseases and an increase in the risk of disease; the fourth is to seriously affect the environment
