Description

A device for loading a charge onto a conveyor sintering machine

The proposed utility model relates to the preparation of iron ore in ferrous metallurgy, and in particular to the designs of sintering equipment.

The closest in technical essence to the proposed technical solution, according to the authors, is a device for loading a charge onto a conveyor agglomeration machine according to a.s. No. 1125459 cells F27B 21/06, containing its storage hopper with a charge discharge window, a drum feeder, a charge flow stabilizer equipped with an air supply manifold and made in the form of two parallel plates arranged with a gap and overlapping one another, as well as a loading tray.

A disadvantage of the known device is the lack of coordination of the rate of air flow from the gap between the collector plates and the pulsation of the material flow. The task to which the technical solution is directed is to coordinate the rate of air outflow from the gap between the collector plates and the pulsation of the material flow, while achieving such a technical result, such as improving the quality of the sinter and increasing the performance of the sintering machine by equalizing the gas permeability of the charge layer along the length .

The aforementioned drawback is eliminated by the fact that the device for loading the charge onto the conveyor sintering machine, comprising a hopper with a charge discharge window, a drum feeder, a flow stabilizer made in the form of an upper and lower plate with the formation of a gap for supplying air from the collector and a loading tray, is equipped with a matching mechanism the rate of air flow out of the slit with a ripple

material flow. In this case, the coordination mechanism is connected to the upper plate of the stabilizer.

A comparative analysis of the proposed technical solution With the prototype shows that the proposed solution is distinguished by its constructive implementation, namely, the presence of a mechanism for matching the rate of air outflow from the gap with the amount of pulsation of the material flow and its connection with the upper stabilizer plate. It follows that the proposed solution meets the criteria of the invention. novelty.

The introduction to the device’s design of a mechanism for matching the speed of air flow from w, spruce between the stabilizer plates with the amount of pulsation of the material flow and its connection with the upper stabilizer plate, makes it possible to equalize the gas permeability of the charge layer along the length, which helps to improve the quality of the sinter and increase the productivity of the sinter machine. It follows that the claimed combination of significant differences previously did not provide such a technical result.

The proposed technical solution will be clear from the following description and the accompanying drawings:

Figure 1 - shows a device for loading the mixture onto a conveyor sinter machine side view.

Figure 2 is a fragment of figure 1, an embodiment of the matching mechanism in the form of a pneumatic cylinder.

In FIG. 3, if a fragment of FIG. 1, an embodiment of a matching mechanism in the form of a counterweight.

A device for loading a charge onto a conveyor sintering machine comprises a hopper 1 with a charge discharge window 2, a drum feeder 3, a flow stabilizer 4 of the charge and a loading tray 5. The flow stabilizer includes an upper b and a lower 7 plate with a slot 8 between them, an air supply manifold 9 matching mechanism 10 associated with

the upper plate b and consisting of a rod 11 and a spring 12.

The matching mechanism can be made in the form of a pneumatic cylinder 13 (see figure 2) or in the form of a counterweight 14 with a system of levers 15 (see figure 3). connected with the upper plate b, and is mounted either on the frame 15, or on the basis of the sintering machine.

A device for loading a charge onto a conveyor sinter machine operates as follows.

The prepared mixture is fed into the hopper 1, from there through the window 2 is dosed with a drum feeder 3 through the stabilizer 4 to the loading. Tray 5.

When leaving window 2, a constant pulsation of the charge flow in thickness and density is inevitable. After this, the charge moves in the radial direction simultaneously with the surface of the drum 3, reaches the upper plate b of the stabilizer 4, is removed by it from the drum and moves straight along it. Under the influence of the weight of the sheath, the upper stabilizer plate b, connected with the matching mechanism 10, moves, thereby changing the height of the slit f-gap) 8 between the plates b and 7 L within 0.03-0.10, as practice has shown from the height of the window issuing 2 sheaves). The mixture in this zone is saturated with air supplied from the collector 9.

From the plate 7, the charge stream with equal gas permeability is loaded onto the loading tray 5 and then onto the sintering trolleys.

From the inevitable pulsation of the charge stream, its weight acting on the upper plate b is constantly changing.

With increasing flow. 1 yacht (by thickness or density), and therefore its weight acting on the plate b, the height of the gap 8 decreases and the rate of outflow of air from it increases. With a decrease in the charge flow, the height of the slit 8 increases and the rate of outflow of air from the slit decreases.

a stream of air with a higher flow rate, and the investigator with a greater penetrating ability, and for less dense - a stream with a lower speed and with less penetrating ability.

Therefore, the coordination of the pulsation flow rate of the charge with the rate of air flow from the gap between the plates b and 7 of the stabilizer ensures that the gas permeability of the charge layer is aligned along its length, which improves the quality of the sinter as a result of equalization of the burning speeds of the sinter along its length, and increases the productivity of the sinter machine increase sintering agglomerate rate.

Thus, the use of the proposed technical solution ensures equalization of the gas permeability of the charge layer along its length, which helps to increase the quality of the sinter and increase the productivity of the sinter machine.
