Abstract

Provided is a local exhaust apparatus. The local exhaust apparatus comprises: a motor member which is installed in an exhaust pipe for guiding and discharging air sucked through an intake port and generates torque when powered, a rotary structure which is located on the leading end of the intake port to rotate with the center of the exhaust pipe as a rotation center and connects to the drive shaft of the motor member, and exterior blades for swirling which are assembled by the medium of an angle adjusting member provided on the exterior of the rotary structure so that the angle of the air intake direction through the intake port can be adjusted and create swirls when rotated. The present invention enables the user to simply regulate the installation angle of the exterior blades generating swirls in order to control the intake area properly according to the intake range of a place to emit exhaust and enables simultaneous generation of swirls and intake-exhaust force using a single drive source.

Description

technical field [0001] The present invention relates to a local exhaust system, and more particularly, to a local exhaust system in which turbulent flow can be controlled simply by adjusting the angle of the turbulence-generating vanes so that the intensity and extent of the turbulent flow can be adjusted according to the pollution source Certain conditions are appropriately changed while the turbulence generating vane and the intake-exhaust vane are driven and rotated by one drive source. Background technique [0002] Generally, a local exhaust system is a set of equipment installed in factories, restaurants, etc. where pollutants are often generated. The local exhaust system is used to provide intake-exhaust force to the inlet as one end of the exhaust pipe, thereby exhausting polluted air from the room to the outside. [0003] Local exhaust systems can be effectively used in situations where: where the local pollution source is located in the bottom area away from the ai...
