Method for utilizing mathematical model to monitor feeding amount of disk feeder

Abstract

The invention relates to a method for utilizing a mathematical model to monitor the feeding amount of a disk feeder, and belongs to the technical field of ingredient mixing. The technical scheme is as follows: a mathematical model of a relation between the actual feeding amount of a disk feeder and the actual rotation speed of a feeding motor is built, and when the actual rotation speed is continuously larger than {(theoretical rotation speed-B)+D} or smaller than {(theoretical rotation speed-B)-D}, the actual feeding amount is larger than or smaller than the set feeding amount; a gap between the actual feeding amount and the set feeding amount can be reflected through the fluctuation situation of real-time rotation speed; and the actual feeding amount of the disk feeder can be monitored according to the mathematical model. The method for utilizing the mathematical model to monitor the feeding amount of the disk feeder has the beneficial effects that as the rotation speed of the motor of the disk feeder increases, the feeding amount increases, and as the rotation speed of the motor of the disk feeder decreases, the feeding amount decreases. Once the rotation speed of the motor of the disk feeder exceeds a set alarm value, an alarm is given, the operating personnel are reminded of looking for the cause, an abnormal burdening state is stopped in first time, and the burdening ratio execution precision is ensured.

Description

technical field [0001] The invention relates to a method for monitoring the feeding amount of a disc feeder by using a mathematical model, and belongs to the technical field of mixing and batching. Background technique [0002] The disc feeder is composed of a feeder and a weighing machine. It is a batching equipment commonly used in iron and steel enterprises. It is used in raw material yards, sintering, coking and other production processes. It has the advantages of sensitivity, reliability and accuracy. For the disc feeder, theoretically, the precision required for production can be achieved. However, in the actual production process, due to the influence of equipment, management and external factors, such as abnormal operation of the weighing idler, belt deviation, abnormal speed measuring device, abnormal sensor, zero point drift, etc., the actual feeding amount will be the same as the design. There is a deviation in the given amount of material; and through the adjust...

However, in the actual production process, due to the influence of equipment, management and external factors, such as abnormal operation of the weighing idler, belt deviation, abnormal speed measuring device, abnormal sensor, zero point drift, etc., the actual feeding amount will be the same as the design. There is a deviation in the given amount of material; and through the adjustment of the batching system itself, the value reflected on the electronic scale is still consistent with the value of the set feeding amount, that is, the data still shows normal, so the batching continues without targeting the system. Detection of problems in the equipment itself; when the deviation gradually increases, the problem can only be found by the naked eye or by using the difference between scales to find the problem, and it is also very lagging, which often leads to inventory deviation, which is difficult to remedy and causes deviations in the quality of ingredients; the execution accuracy of ingredient ratios It determines the batching structure, cost, technical and economic indicators, as well as the physical and chemical properties and metallurgical properties of the product, and plays a pivotal role in the production of the blast furnace. The quality of the batching directly affects the production of the blast furnace. bad influence
