Abstract

The invention discloses a powder measuring and conveying system comprising a conveyor, a feeding device, a measuring hopper, a blanking regulating valve and a control device; the feeding device is arranged at a feeding hole of the conveyor; the measuring hopper is arranged at a discharging hole of the conveyor; the blanking regulating valve is arranged between the discharging hole and an inlet of the measuring hopper; and the control device is used for controlling the blanking regulating valve and the conveyor according to the relation between a preset measured value and an actual measured value of powder in the measuring hopper and is connected with the blanking regulating valve, the conveyor and the measuring hopper. In the powder measuring and conveying system, the blanking speed can be changed at the right moment according to the actual blanking condition due to the control action of the control device, so that the multistage precise control for the blanking regulating valve and the conveyor is realized, the measuring precision and the production quality of the system can be favorably improved, and the work efficiency is relatively high. The invention also discloses a powder measuring and conveying method by which the high-speed precise control for blanking can be realized.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a powder metering and conveying system. In addition, the invention also relates to a method for metering and conveying powder. Background technique [0002] When filling gobs in mines, it usually needs to go through processes such as feeding, storing, and batching, and the above-mentioned processes basically involve the metering and transportation of powder. [0003] When filling powder materials such as fly ash, admixture or cement, it is often required to input quickly. At the same time, the measurement accuracy of the added powder is high, and the inaccurate measurement may have a great impact on the filling effect. In an existing typical powder metering conveying system, a large-diameter screw conveyor is used to convey powder. In this powder metering conveying system, the feeding diameter of the conveyor is large, which can meet the requirements of fast conve...
