Loosening device for thick material layer of vanadium-titanium sintering machine and using method of loosening device

Abstract

The invention discloses a loosening device for a thick material layer of a vanadium-titanium sintering machine and a using method of the loosening device. The loosening device comprises a trolley and a first working box, first linear modules are arranged on the two sides of the trolley, second working boxes are arranged at the tops of the first linear modules, hydraulic cylinders are arranged in the second working boxes, and second sliding blocks are fixedly connected with the output ends of the hydraulic cylinders; and a movable plate is slidably connected between the two second working boxes, the second sliding blocks are fixedly connected with the movable plate, a material receiving box is slidably connected with the interior of the movable plate, a discharging opening is formed in the bottom of the material receiving box, and a material blocking mechanism is arranged at the bottom of the material receiving box. The loosening device has the beneficial effects that by arranging a screening mechanism, raw materials are screened; by arranging a reset mechanism, a screening box is reset; by arranging the first linear modules, the second working boxes drive the movable plate to move; and by arranging a material blocking mechanism, discharging control over the material receiving box is achieved.

Description

technical field [0001] The invention relates to the technical field of vanadium-titanium sintering machines, in particular to a loosening device for a thick material layer of a vanadium-titanium sintering machine and a use method thereof. Background technique [0002] The sintering machine is suitable for the sintering operation of large-scale ferrous metallurgical sintering plants. It is mainly suitable for the sintering treatment of iron ore powder in large and medium-sized sintering plants. When the vanadium-titanium sintering machine is sintered, it is necessary to lay a thick material layer at the bottom, which refers to the thick material layer Sintering is an iron ore sintering process in which the sintering furnace grate is kept at a high thickness. It can effectively improve the quality of sintered ore: improve the mechanical strength of sintered ore, reduce the amount of powder, reduce the content of ferrous oxide (FeO), and improve the reduction performance. Gener...

AI Technical Summary

Problems solved by technology

It can effectively improve the quality of sintered ore: improve the mechanical strength of sintered ore, reduce the amount of powder, reduce the content of ferrous oxide (FeO), and improve the reduction performance. Generally, the raw materials of thick material layer are laid on the trolley, and loosening is required when laying. However, the existing loosening device is not convenient for screening the raw materials in advance, resulting in low working efficiency of the sintering machine, and the existing loosening device is not convenient for equalization and laying, and the loosening efficiency is low
