Ventilation device applicable to SPF-grade experimental animal raising equipment

Abstract

The invention discloses a ventilation device applicable to SPF-grade experimental animal raising equipment. The ventilation device comprises a ventilation panel, a plurality of ventilation ports and an air volume adjusting plate, wherein the ventilation ports are formed in the ventilation panel; the air volume adjusting plate is rotatably arranged on the ventilation panel through a rotating shaftand provided with openings corresponding to the ventilation ports one by one, and ventilation passages for passing of air flow are formed when the openings and the ventilation ports are partially overlapped with each other. The micro-barrier-environment experimental animal raising equipment comprises the ventilation device. According to the ventilation device applicable to the SPF-grade experimental animal raising equipment, by rotating the air volume adjusting plate to make the openings and the ventilation ports partially overlapped with each other, the ventilation passages for passing of airflow are formed, the size of the ventilation passages can be adjusted by rotating the air volume adjusting plate in order to adjust the air flow passing through different sectional areas and furthercontrol the air volume, and the air volume can be conveniently controlled.

Description

technical field [0001] The invention relates to the technical field of experimental animals, in particular to a ventilation device suitable for raising SPF level experimental animal equipment and micro-barrier environment experimental animal feeding equipment with the ventilation device. Background technique [0002] In the prior art, experimental animal breeding equipment usually includes a breeding box, a cage frame placed in the breeding box, multi-layer and multi-row cage boxes placed in the cage frame, an air supply device, a return air device, and a temperature and humidity monitoring device. After the indoor air is filtered, it enters the cage frame and cage box through the air supply duct of the air supply device, and the exhaust gas from the animals is quickly discharged out of the breeding box through the return air duct of the air return device. [0003] However, according to the number of experimental animals in the breeding equipment and the growth conditions, e...

Problems solved by technology

[0003] However, according to the number of experimental animals in the breeding equipment and the growth conditions, etc., the ventilation volume in the breeding box also has a certain change. However, the ventilation volume in the breeding box is generally determined by the air supply device or the pipeline in the return air device. The size is determined, and the air volume cannot be controlled
