Description

Technical Field

[0001] The utility model relates to the technical field of fresh air ventilation, in particular to a fresh air ventilation device for pig breeding. Background Technique

[0002] The fresh air ventilator is designed and developed based on the principle that when air is supplied on one side and exhausted on the other side in a closed room, a "fresh air flow field" will be formed in the room. It relies on mechanical air supply and exhaust to force a fresh air flow field to be formed in the system. It is used in pig houses for pig breeding to promote air circulation and improve the pig breeding environment.

[0003] For example, the Chinese authorized patent (a fresh air ventilator) with the publication number of CN109827281B: includes a machine shell, a top plate, a heat exchange core, a blower and an exhaust fan; the top plate covers the opening at the top of the machine shell, and a fresh air duct and a dirty air duct are arranged separately in the machine shell; multiple installation ribs for installing the heat exchange core are arranged in the machine shell, and the multiple installation ribs form a space for clamping and installing the heat exchange core. The installation ribs are provided with Y-shaped installation grooves, and Y-shaped sealing gaskets for sealing the heat exchange core are arranged in the Y-shaped installation grooves; the heat exchange core is provided with a first air duct and a second air duct that are isolated from each other. The first air duct is communicated with the fresh air duct, and the second air duct is communicated with the dirty air duct. The fresh air ventilator provided by the present invention facilitates the installation of the heat exchange core in the machine shell of the fresh air ventilator and improves the sealing effect between the heat exchange core and the machine shell.

[0004] However, most of the existing fresh air ventilators for pig breeding are fixed in the ceiling through fixing bolts. When fixing multiple fresh air ventilators, it is time-consuming and laborious, and it is not easy to adjust the position. Multiple adjustments and drilling are required, resulting in inconvenient installation and replacement; therefore, it does not meet the existing requirements, and for this reason, we propose a fresh air ventilation device for pig breeding.
