The invention provides a sintering plant complex raw material proportioning control system. The sintering plant complex raw material proportioning control system comprises a feeding belt weigher, a proportioning bin, a weighing sensor, feeding equipment and a controller. The feeding belt weigher is located above the proportioning bin, and weighs raw materials entering the proportioning bin. The weighing sensor is used for weighing the weight of the raw materials in the proportioning bin, and measurement data of the feeding belt weigher and the weighing sensor is transmitted to the controller.The controller generates a distribution table of the raw materials in the bin, a raw material dynamic ratio is obtained, and the feeding speed of the feeding equipment is controlled according to the raw material dynamic ratio. According to the system and a method, the distribution table of the raw materials in the bin is generated according to the weighing value of the proportioning bin feeding belt weigher and the weighing sensor, the raw material dynamic ratio is calculated, and the feeding speed of the feeding equipment is subjected to closed-loop control; and automatic control of the sintering plant complex raw material proportioning control system is achieved, the raw materials are utilized to the maximum extent, and production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of industrial computer real-time control, and more specifically, to a complex raw material batching control system and method for a sintering plant. Background technique [0002] The batching system of the sintering plant is one of the important links of the sintering process. Through the raw material feeding system, raw materials such as iron-containing raw materials, solvents, fuels, and returned ore are stored in their own batching bins. During the batching production process, the batching bin conveys the raw materials in the bin to the large belt through the feeding equipment below, and sends them to the raw material mixing system uniformly. When batching, each raw material needs to be configured in proportion, and the computer adjusts the batching proportion of each raw material by adjusting the feeding speed of the feeding equipment. With the development of science and technology, the sintering proce...
