Abstract

The invention discloses a fan with an adjustable ventilation door. The fan comprises a fan assembly and an air duct assembly, wherein the air duct assembly is arranged below the fan assembly; an air amount adjusting device which can be used for adjusting the air amount of the air duct assembly is arranged in the air duct assembly; the fan assembly comprises an installing frame, an installing bracket which is fixedly connected with the installing frame, a motor installing plate which is fixedly connected with the installing bracket, and a driving motor which is fixedly connected with the motor installing plate; a blade is connected with the driving motor, and is driven by using the driving motor; and the air amount adjusting device comprises a rotatable first and second blade. According to the fan with the adjustable ventilation door disclosed by the invention, a user can adjust the opening of the entire ventilation door manually or automatically by using two semicircular ventilation door blades, and the fan has the advantages of large adjusting range and quick response.

Description

[0001] technical field [0002] The invention relates to an industrial ventilation device, more precisely, a fan with an adjustable damper. [0003] Background technique [0004] In the chemical industry, it is often necessary to use fans with adjustable dampers as ventilation equipment. Existing fans with fans, especially vertical fans, are generally unable to adjust the ventilation volume of the entire fan. At the same time, the mounting brackets of the motors of existing fans are too bulky, and such heavy brackets lead to high installation costs of fans. No more. [0005] Chinese invention patent application 201010121360.9 discloses a fan impeller, the fan impeller includes: a substantially cylindrical cup; and a plurality of blades, the plurality of blades are arranged on the outer peripheral surface of the peripheral wall of the cup. The cup portion includes a plurality of axially extending first ribs and a plurality of second ribs disposed between the first ribs on ...
