Distribution control method and system of sintering machine

Abstract

The embodiment of the invention discloses a distribution control method and system of a sintering machine. The system comprises a bin, a main door, multiple auxiliary doors, a round roller, material flow state detection devices, an execution mechanism and a controller. A discharging opening of the bin communicates with the main door. The main door is connected with the multiple auxiliary doors incooperation. The main door and the auxiliary doors are all located at the position, above the round roller, of the discharging opening of the bin. At least one material flow state detection device ismounted on each auxiliary door. The material flow state detection devices are connected with the controller, and the controller is used for judging whether the material flow state of materials betweenthe auxiliary doors and the round roller is normal or not according to the detection result of the material flow state detection devices. When the material flow state is abnormal, the first opening degree of each auxiliary door is adjusted to the second opening degree, wherein the second opening degree is larger than the first opening degree. By means of the system, the situation of clamping of large blocks in the auxiliary doors can be found in time, large blocks can be discharged in time by automatically adjusting the opening degrees of the auxiliary doors, the material flow state is rapidly restored to normal, and the defect that hysteresis quality exists due to manual treatment in the prior art is avoided.

Description

technical field [0001] The present application relates to the technical field of sintering, in particular to a method and system for controlling the distribution of sintering machine. Background technique [0002] Iron ore sintering refers to the sintering of iron ore powder, coal, flux ore and other sintering raw materials through batching, primary mixing, secondary mixing, cloth distribution, sintering, ring cooling, screening, dust removal, etc., to obtain sintered iron ore with sufficient strength and particle size Sinter. Among them, the material distribution link in the sintering production process has a crucial impact on the quality of sinter ore. If the surface of the material layer on the background car of the material distribution is flat and the thickness of the material layer is uniform, the overall air permeability of the material layer can be improved. , Improve the quality of sinter. [0003] Such as figure 1 As shown, in the distributing link of the sinter...
