The invention discloses an air volume measuring structure based on a flow equalizing technology. The structure comprises a primary air pipe, a secondary air pipe, a flow equalizing element and an air measuring element, an air inlet is formed in one end of the primary air pipe, a grinding inlet is formed in the other end of the primary air pipe, the secondary air pipe is located at the lower end of the air inlet and communicated with the primary air pipe, and the flow equalizing element is used for dividing, mixing and guiding air flows introduced into the primary air pipe and the secondary air pipe; and the wind measuring element is used for measuring the air volume of the mill inlet and is fixed with the primary air pipe. The invention discloses an air volume measuring structure based on a flow equalizing technology. The air volume measuring structure can solve the problem that primary air volume and secondary air volume of an inlet of an existing coal mill are not accurately measured. 本发明公开了一种基于均流技术的风量测量结构。
