Dynamic control method and device for sintering distributor

Abstract

The invention discloses a dynamic control method and device for a sintering distributor. The method comprises the following steps: detecting a first discharge flow of a first distribution bin and a second discharge flow of a second distribution bin if the first distribution bin and the second distribution bin discharge simultaneously; comparing the first discharge flow and the second discharge flow and obtaining a comparison result; determining a first distribution time of the first distribution bin and a second distribution time of the second distribution bin of the distributor according to the comparison result, and determining the total quantity of materials changing in real time; if the sum of the detected total quantity of materials of the first distribution bin and the detected total quantity of materials of the second distribution bin is bigger than a set threshold, determining the distribution bin which is currently feeding and calculating the starting feeding time, and controlling the distributor to distribute materials to the distribution bin which is currently feeding within the starting feeding time; switching the distribution positions; and controlling the distributor to alternatively distribute materials to the first distribution bin and the second distribution bin within the first time and the second time according to the switched distribution positions.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a dynamic control method and device for a sintering distributor. Background technique [0002] The sintering system is generally composed of a single-batch mixing system, a material distribution system, a granulation system and a cooling system, among which the granulation system mostly adopts two sets (granulation system 1 series and granulation system 2 series), and the sintering system is a single series quenching system or dual series quenching system, see figure 1 Schematic diagram of the structure of the sintering system shown. Among them, the material distribution system is responsible for proportionally distributing the mixture from the batching and mixing system to different granulation systems, which plays a very important role in the continuous and stable production of the entire system. Usually, the material distribution system consists of It is composed of the feed...

Problems solved by technology

[0004] The conventional feeder adopts timing switching, combined with the manual distribution method. In this way, the feeding time is usually given for both distribution bins, and when the time is over, it will switch to another distribution bin for feeding. When the material level of a sub-material bin is too full or too empty, the operator is forced to adjust the feeding of the sub-material bin. If it is too full, the feeding will be reduced, and if it is too empty, the feeding will be strengthened. The sintering production link of the variable is too frequent to be manually operated, and the automatic material distribution function cannot be realized
