Abstract

The invention discloses a large-scale industrial fan which comprises a motor, a plurality of fan blades and a fan blade fixing disc. A working spindle of the motor is connected with the fan blade fixing disc, and the plurality of fan blades are fixedly connected with the fan blade fixing disc. The large-scale industrial fan is characterized in that a pulling rope connecting piece is further arranged on the fan blade fixing disc, the pulling rope connecting piece and the plurality of fan blades are connected through pulling ropes respectively, and the fan blades are pulled through the pulling ropes. The large-scale industrial fan improves fan blade balance, long fan blades are pulled by setting a pulling device of the fan blades, and fan blade bending and deformation caused by large length is avoided, so that the fan blades can be in a balanced state throughout. The fan blades can be made longer to cover larger space so that use amount of fans is reduced, and the large-scale industrial fan is energy-saving and safe and reduces the cost.

Description

technical field [0001] The invention relates to a fan used in a large space environment, especially suitable for industrial production workshops with a large area. Background technique [0002] In some industrial production environments with relatively large space areas, the indoor temperature is high in summer, and it is a good choice to use fans for cooling and ventilation. Ordinary fans have small diameter, high speed, low air volume, high noise, and high power consumption, so it is a good choice to use a large industrial fan with a large diameter. However, due to the large diameter of ordinary large-scale industrial fans, the length of the blades used is also large, and the lack of support for the blades makes the blades easy to bend and deform, which affects the normal operation of the fan. Even the fan blade is broken at the root, unable to work and a safety hazard. Contents of the invention [0003] The technical problem mainly solved by the present invention is t...
