Feeding control method for bunkers of sintering proportioning system and feeding control device for bunkers

Abstract

The invention provides a feeding control method for bunkers of a sintering proportioning system, which includes the steps of acquiring working states of the sintering proportioning system, and if the sintering proportioning system is in the opening working state, acquiring identity information of the bunkers selected through switching, and controlling the bunkers to feed immediately after the bunkers with the identity information are started. Besides, the invention further provides a feeding control device for the bunkers. By means of automatically acquiring the working states of the system, the identity information of the bunkers selected through switching is acquired when the system is guaranteed to be in the opening state, and further the bunkers with the identity information are controlled to feed immediately after being started, so that starved feeding of material piles conveyed onto a mixing belt is ensured. Besides, in order to ensure that the selected bunkers can normally discharge materials to the mixing belt, the use proportion of the materials of the bunkers is required to be larger than zero. Since starved feeding of the material piles is avoided, on one hand, quality of a sintering process can be effectively ensured, and on the other hand, energy consumption can be reduced.

Description

technical field [0001] The present invention relates to the field of control technology, in particular to a method and device for controlling material feeding in a silo of a sintering batching system. Background technique [0002] like figure 1 Shown is a schematic diagram of the system structure of the sintering batching system, wherein the silo group can include a plurality of silos 10, and each silo 10 contains a material (the material can include mixed ore, limestone, returned ore, and miscellaneous materials) etc.), at least one blanking disc 11 is arranged below the feed bin, and a blanking belt scale 12 is respectively arranged at the outlet of each blanking disc, the blanking disc 11 and the corresponding blanking belt scale 12 constitute a blanking row. When the sintering batching system is working, each silo discharges the materials contained in the silo to the unloading disc in a certain proportion according to its own preset delay time, and then unloads the mat...

AI Technical Summary

Problems solved by technology

During the normal batching process, the system needs to be at T 2 time to collect fuel, but after switching to No. 3 silo, No. 3 silo will be in T 3 At this time, the stockpile has been transferred to other silos to collect other materials, so the materials collected on the mixing belt appear to be short of fuel.

[0005] If the system is sintered in the absence of a certain material, it will affect the quality of the finished product

For example, if there is a lack of certain fuel in the mixture or the proportion of fuel is too low, then the mixture cannot be fully sintered, resulting in a large number of waste products; if there is a lack of certain flux in the mixture or the proportion of flux is too low, it will The alkalinity of the finished product is too low, and it is still a waste product

In order to avoid sintering waste products in the case of material shortage, under normal circumstances, the mixture lacking certain materials is regarded as waste material, and it is not sintered, which causes a great waste of resources
