Device and method for accurately conveying fibers

The invention belongs to the technical field of oil exploitation, and particularly relates to a device and method for accurately conveying fibers. The device for accurately conveying fibers achieves accurate addition of fibers through the real-time measurement and weighing and automatic adjustment technologies. A real-time measurement and weighing device measures all the mass on a fiber air feeding device so that the mass of the fibers leaving an instrument can be accurately worked out; initially, the fibers are added at a reel speed, and when it is worked out that the addition speed of the fibers does not accord with the actual design speed, the designed fiber addition speed is achieved by adjusting the reel speed through the automatic adjustment technology. The problem that in the existing oil exploitation crushing process, the addition method of the fibers can not meet the requirement for accurately adding the fibers is solved. The speed is adjustable, operation is convenient, and measurement is accurate.
