Device and method for controlling discharge of sintering bunker group

Abstract

The invention provides a device for controlling the discharge of sinter bunker group. The device comprises: a level detector for obtaining current level values of bunkers by means of detection; a discharge flow setting value acquisition unit for acquiring discharge flow setting values to which the bunkers are corresponding; an ideal flow value allocation unit for allocating, according to the current level values and the discharge flow setting values of the bunkers as well as a preset allocation rule, ideal discharge flow values to the bunkers to which raw materials of the same type are corresponding respectively; and a discharge control unit for controlling the discharge of bunkers according to the ideal discharge flow values of the bunkers. The invention further provides a method for controlling the discharge of sintering bunker group. By adopting the device and the method, coordinated discharge between the bunkers, to which raw materials are corresponding, in a sintering system discharge group can be achieved.

Description

technical field [0001] The invention relates to the field of iron and steel smelting, in particular to a control device and method for unloading a sinter bin group. Background technique [0002] refer to figure 1 , is the process flow diagram of the batching system of the sintering plant. [0003] The batching workshop of the sintering plant is equipped with several large silos 1 along the mixing belt, which are used to store various materials required for sintering production, such as iron materials, fuels, fluxes, returned ore, and miscellaneous materials. Each ore tank 1 feeds to a mixing belt, and finally forms the mixed material of 13 feed bins 1 at the end of a mixing belt. The above is often referred to as the batching system. The batching system controls the discharge flow rate of each silo 1 in proportion according to the comprehensive delivery volume, and then controls the chemical composition of the sintered product. The raw materials on the mixing belt are se...

Problems solved by technology

However, the existing feeding method has many disadvantages

[0006] First of all, using manual switching requires operators to operate from time to time, which is a waste of manpower and is very troublesome

At the same time, since the unloading trolley does not distribute the materials evenly to each silo, it is easy to cause a material level in a certain silo to be too high and cause a backlog of raw materials, or a certain The phenomenon that the material level of a silo is too low to waste silo resources
