System and method for controlling material level of sintering mixing material bin

Abstract

The invention belongs to the technical field of industrial computer real-time control, in particular to a system and method for controlling a material level of a sintering mixing material bin. The system is characterized by comprising a real-time monitoring mechanism, a signal acquisition and analysis mechanism and a control execution mechanism, wherein the real-time monitoring mechanism comprisesa charging belt weigher positioned above the mixing material bin, bin weighing sensors arranged on the mixing material bin, a round roller feeder positioned below the mixing material bin, and a converter detection speed feedback device arranged on a sintering machine; the signal acquisition and analysis mechanism comprises a computer analysis system; and the control execution mechanism comprisesa logic controller. The system and method for controlling the material level of the sintering mixing material bin can diagnose and analyze on-site abnormal conditions according to on-site signals, draw an expected trend curve of the material level of the mixing material bin, and give a solution for restoring the normal material level, thereby realizing the intelligent control of the material levelof the mixing material bin, shortening the time for adjusting the abnormal material level, increasing the sinter output and increasing the production profit of a whole plant.

Description

technical field [0001] The invention belongs to the technical field of industrial computer real-time control, and in particular relates to a system and method for controlling the material level of a sintering mixing bin. Background technique [0002] The sintering machine is the main equipment for sintering production, and its feeding source is the mixing bin on the top of the head of the sintering machine, and the mixing bin is fed by the mixed raw materials produced by the batching system. As an intermediate link between the batching system and the sintering system, the mixing silo plays a vital role. Whether sufficient and stable raw materials can be ensured in the mixing silo is the prerequisite for the sintering machine to be able to produce at full capacity, which directly determines the annual economic benefits of the sintering plant. Under normal production conditions, when the output of the batching system maintains a certain ratio to the output of the sintering sy...

AI Technical Summary

Problems solved by technology

However, when the batching or sintering equipment fails to cause the system to shut down temporarily, or a certain system causes abnormal output due to some reason, the material level in the mixing silo will change greatly

Under the traditional production mode, restoring the mixing bin material level to a stable range requires the operator to repeatedly adjust the input and output volumes, which not only wastes time, but also reduces the output of sinter
