A dual-mode high-speed ducted ventilation fan

Abstract

The invention relates to a dual-mode high-speed pipeline type ventilating fan. The brand new structural design is adopted, the design of a double-effect accelerated air supply mechanism is introducedbased on an existing structure of a ventilating pipeline (1), an electric fan is additionally arranged based on a bearing (2) designed and arranged on the inner wall of the ventilating pipeline (1), and meanwhile through cooperation of a driven wheel (3) fixedly connected to a fan outer frame (6) in the electric fan and a driving wheel (4) which is connected through a belt (9), the electric fan can rotate in an inner ring of the bearing (2) under driving of a rotating motor (5); and thus, through cooperation of rotation of motor fan blades (7) in the electric fan, the motor fan blades (7) canrotate at a higher speed in space, a more efficient air driving effect can be achieved aiming at air in the ventilating pipeline (1), and the ventilating efficiency can be effectively improved.

Description

technical field [0001] The invention relates to a dual-mode high-speed duct type ventilation fan, which belongs to the technical field of ventilation ducts. Background technique [0002] Ventilation ducts refer to the ducts used for ventilation and ventilation, which are arranged on the top surface of each floor in the building to achieve air exchange for indoor air and achieve the purpose of purifying the air. In specific implementation, based on the ducts distributed in the building, Combined with the fan installed in the duct, a huge airflow is generated in the duct to achieve air convection in each closed area. However, as the scale of existing buildings continues to expand, the scale of ventilation ducts is also increasing day by day. For large-scale ducts, naturally Fans with higher power need to be configured to generate air convection in the pipes connecting each area. Therefore, the power of the fans in the existing ventilation pipes is constantly upgraded, so that ...

[0002] Ventilation ducts refer to the ducts used for ventilation and ventilation, which are arranged on the top surface of each floor in the building to achieve air exchange for indoor air and achieve the purpose of purifying the air. In specific implementation, based on the ducts distributed in the building, Combined with the fan installed in the duct, a huge airflow is generated in the duct to achieve air convection in each closed area. However, as the scale of existing buildings continues to expand, the scale of ventilation ducts is also increasing day by day. For large-scale ducts, naturally Fans with higher power need to be configured to generate air convection in the pipes connecting each area. Therefore, the power of the fans in the existing ventilation pipes is constantly upgraded, so that both energy consumption and noise are proportional to the power. Therefore, there is still room for further improvement in the existing ventilation duct structure technology
