Description

The invention relates to the preparation of ore raw materials in metallurgy, in particular, to the design of sintering equipment, and can be used in ferrous and nonferrous metallurgy when loading the charge on sintering carts of sintering machines.

The aim of the invention is to increase the productivity of the sintering machine and reduce fuel consumption.

FIG. 1 shows the device with the installation of peripheral and central rectangular shelves at the same angle, general view; in fig. 2 is a view A of FIG. one; in fig. 3 - device with installation of peripheral and central rectangular shelves at different angles, general view; in fig. 4 is a view B in FIG. 3

The device for loading the charge on sintering carts contains a hopper 1 with a window 2 for dispensing material, a drum feeder 3, a stabilizer 4 with central and peripheral shelves 5 and 6, respectively, a turn system 7 of shelves 5 and 6, and a loading tray 8. includes lifting and lowering shaft 9 with adjusting screw. The stabilizer 4 has a width equal to 0.1-0.3 of the diameter of the drum 3 pittetl to completely block the flow of the charge, and is set at an angle of + 15 °, ..., -20 ° to the horizon depending on the granulometric composition of the charge. The length of the discharge part of the central shelf 5 of the stabilizer is 0.5-0.8 of the length of the entire stabilizer, which ensures the optimal structure of the batch on the sintering machine.

In order to simplify the system for rotating the shelves, it is advisable to center the shelf in a T-shape, and place the peripheral shelves in the recesses of the central shelf. In this case, the width of the peripheral shelves is 0.3-0.6 the width of the stabilizer. Peripheral shelves on each side of the central may be one or two depending on the width of the sintering cart. The device works as follows. The prepared mixture is fed to the storage bin 1 and from there through the window 2 is dispensed with a drum feeder 3 to the charging chute 8. After leaving the window 2, the charge first moves in a radial

the direction simultaneously with the surface of the drum, reaches the central and peripheral shelves 5 and 6, respectively, of the stabilizer 4, is removed by them from the drum and moves linearly along an inclined plane. With such a change in the nature of the movement, the arrays of the charge are destroyed. From the stabilizer, the charge enters the loading chute 8 and is placed on the sintering carts of the sintering machine.

Shelves 5 and 6 have different angles of inclination. In the central shelf 5, which has a minimum angle of inclination to the horizon, the charge is loosened and placed on carts with increased porosity. On the peripheral, more inclined shelves 6, the charge, due to a larger backpressure, is compacted when loaded to the specified values, depending on the angle of inclination of the shelf.

The application of the proposed device provides an increase in the gas permeability of the batch, which, in turn, can be used to increase the vertical speed of the special and increase the productivity of the sintering machine, as well as increase the height of the sintered layer and reduce fuel consumption.
