Embodiment Construction
[0018] In order to clearly illustrate the technical characteristics of this solution, the following will describe this solution through specific implementation modes and in conjunction with the accompanying drawings.
[0019] A mosaic-type sintering distribution auxiliary device, as shown in the figure, it includes a vertical limiting plate 4, the vertical limiting plate 4 is located at the outlet end of the multi-roll distributor 7, above the sintering trolley 9, the multi-roll distribution The inlet end of device 7 corresponds to the discharge end of round roller feeder 6. A blanking passage is left between the vertical limiting plate 4 and the multi-roller distributor 7, the vertical limiting plate 4 and the sintering trolley 9 form a storage space for materials, along the running direction of the sintering trolley 9, The vertical limiting plate 4 and the multi-roller distributor 7 are arranged in sequence.
[0020] The upper and lower ends of the vertical limit plate 4 ar...

The invention provides an inlaid type sintering and distributing auxiliary device. The inlaid type sintering and distributing auxiliary device comprises a vertical spacing plate, the vertical spacing plate is located at the outlet end of a multi-roll distributing device and located on a sintering table, a discharge passageway is reserved between the vertical spacing plate and the multi-roll distributing device, material storage space is defined by the vertical spacing plate and a sintering pallet, an upper end of the vertical spacing plate and a lower end of the vertical spacing plate are connected with adjustment assemblies respectively, each adjustment assembly comprises a horizontal support rod and a power device which drives the horizontal support rod to move horizontally, the power device is installed in a shell body, and two ends of each horizontal support rod are hinged to the corresponding power device and the vertical spacing plate. By means of the inlaid type sintering and distributing auxiliary device, large particles of a mixing material being evenly inlaid into an integral material layer can be achieved, the segregation of the mixing material is restrained, moisture deviation of an upper material layer and a lower material layer is improved, the fuel availability is improved, and the pig-iron cost is lowered.
Description
technical field [0001] The invention relates to a mosaic-type auxiliary device for sintering and distribution, which belongs to the technical field of ironmaking and sintering, and realizes sintering and distribution under economic material production conditions. Background technique [0002] The cost reduction and efficiency increase work of iron and steel plants is an important focus of iron and steel enterprises at present. The structure of sintering raw materials has undergone tremendous changes, and the previous fine material policy has become history. The current raw material structure is a high proportion of Sierra Leone coarse powder + high-silicon coarse powder. The economical efficiency of these two main materials is very good, which provides a favorable support for the reduction of the cost per ton of iron. Because the particle size of this kind of ore is relatively coarse, the impurity components aluminum and silicon content are extremely high, and the sintering ...
