Description

The invention relates to devices for handling materials using movable chutes and can be used to distribute bulk materials into containers. In ferrous metallurgy, for example, the device can be used to distribute hot sinter into weight funnels and then feed it with skips to the blast furnace.

A device for distributing a material flow during loading of containers, made in the form of a dual-stage divider with a swing axis and containing a mechanism for changing the position of the center of gravity of the device, made in the form of a cargo suspended on a flexible link 1.

However, such a device is not intended to distribute the flow of material into several containers, but only solves the problem of distributing the flow of material across the width of one container. In addition, the absence of rotation or horizontal movement in the drive device prevents it from being used for the distribution of several material flows.

Closest to the proposed technical essence and the achieved effect is a device for distributing charge materials into the blast furnace skips, which contains a double-slope chute mounted on a trolley equipped with a displacement drive 2.

A disadvantage of the known device is that the electric drive of the trolley is located in the working area of the dual-slope chute in a dusty atmosphere and is subjected to considerable thermal and mechanical stress when loading charge materials, especially hot sinter, whose temperature reaches 800 ° C. The electric cable that feeds the electric drive is also subjected to the same effect, which is also subject to heavy wear when it is dragged behind the drive carriage. All this reduces the reliability of the device. In addition, when loading material into the vessel due to the effect of the material flow only on one of the slopes of the dual-slope chute, a horizontal shearing force acts on the trolley, which does not allow the dual-slope chute to be installed in any fixed position along the width of the loading opening of the containers. The dual-slope chute is mounted above each of the containers in only one fixed position when the carriage approaches the stops installed in its extreme positions. Such an embodiment of the device reduces the filling ratio of the containers.

The purpose of the invention is to improve the reliability of the device, the accuracy of fixing the position of the gutter across the width of the loading opening of the containers.

This goal is achieved by the fact that in a device for distributing bulk materials in containers containing a dual-slope chute mounted on a trolley, and a movement drive, the movement movement of a trolley is made in the form of two weights of different weights, each of which is connected by a flexible connection with opposite ends of the trolley , and the load with a larger mass is equipped with a lifting mechanism.

The drawing shows a diagram of the device.

The device contains two lamellar conveyors 1 for transporting hot sinter, double-slope chute 2 mounted on trolley 3, moving along rails 4 limited by abutments 5 and 6. At opposite ends of trolley 3 fixed rocker arms 7 and 8 are connected by flexible links 9 and 10 through the blocks 11 and 12 with weights 13 and 14. The load 13 is equipped with a lifting mechanism 15, made in the form of a winch, and has a mass twice as large as the weight of the load 14. Under the dual slope chute 2 there are two weight funnels 16 and 17 for weighing hot agglomerate and n The next boot it in skips 18 and 19.

The device works as follows.

In order to load the agglomerate from the plate conveyors 1 into the weighing hopper 16, the carriage 3 with the dual slope chute 2 is set to the extreme left position. The agglomerate from the conveyors 1 along the right slope of the dual-slope chute 2 fills the volume A. (shaded) the weight funnel 16. To move the dual-slope groove 2 to the right along the width of the weight funnel 16, the drive winch 13 lifts the load 13. At the same time, the trolley 3 under the load 14 moves right along the rails 4. When the drive winch is turned off, the trolley 3 stops and its position on the rails 4 is automatically fixed, as the flexible connections 9 and 10 tighten under the action of loads 13 and 14 both to the right and to the left. Moving the trolley 3 along the width of the loading opening of the weighing funnel 16 allows filling the volume B of the weighing funnel 16. The dual trough chute is moved to the far right position to fill the weighing funnel 17, for which the weight 13, which is twice the weight of the load 14, is lowered by means of a drive winch. Due to this ratio of the masses of weights 13 and 14, the same effect is exerted on the carriage 3 when it is moved both to the right and to the left. When moving the trolley 3 to the right (when lifting the load 14), the trolley 3 has a horizontal force equal to the weight of the load 14, and when moving the trolley 3 to the left (when lowering the load 13), the force is equal to the difference of the weights of the loads 13 and 14, which is numerically equal to the mass cargo 14. Filling the weighing funnel 17 with an agglomerate is similar to filling the weighing funnel 16.

The use of the proposed device for the distribution of hot sinter into weighing funnels significantly increases the reliability of the drive of movement of the dual-slope chute, since the drive is removed from the zone of operation of the chute. In addition, the dynamic loads from the material falling onto the gable chute are not transferred to the drive, as is the case in the prototype. Drive drive

gantry in the form of weights allows the gabled chute to be moved across the width of the loading opening of the weight funnels and, when the gutter stops, to automatically fix the chute in any position without using any additional devices, which increases the filling factor of the weight funnels.

The economic effect of using the device is 28,800 rubles. per year per blast furnace.
