Abstract

The invention relates to the technical field of air blowers, in particular to a cold air circulation type air blower which comprises a shell, an impeller, an adjusting assembly, a power unit and an air inlet, a worker controls the power unit, and part of elements in the power unit adjust the working state of elements in the adjusting assembly by changing the motion state of the output end; therefore, the working states of the multiple impellers are adjusted, gear adjustment of the air blower is achieved, then the air pressure of the air blower is changed so as to adapt to the actual production requirement, the cost input of early-stage auxiliary equipment is small, the integration degree of the device is high, the installation and use process is simple, and air pressure adjustment of the air blower can be achieved only through power equipment with the common price. The air pressure of the air blower does not need to be changed by additionally arranging a frequency converter or a transmission or directly adopting an expensive speed regulating motor.

Description

technical field [0001] The invention relates to the technical field of blowers, in particular to a cold air circulation type blower. Background technique [0002] The blower is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine and is widely used in various industrial sectors. People often divide the blower into two categories: centrifugal blower and axial flow fan. When the centrifugal blower is working, the fan impeller rotates at a high speed, so that the air around the fan impeller is thrown out to generate negative pressure, so that "new air" is continuously replenished from the air inlet, which constitutes the normal working state of the fan. When the fan blade in the flow fan rotates, the blade pushes the air along the axial direction of the air outlet, and a certain negative pressure is formed at the air inlet, and the new air is replenished to maintain the normal working state. [00...
