Abstract

A sintering trolley of an agglomeration machine, comprising a base on which running and load rollers, grates and boards are mounted, consisting of upper and lower parts, the latter of which are provided with longitudinal spikes included in the corresponding recesses of the upper part of the base, characterized in that the said recesses are made in in the form of covering guides of the "dovetail" type, with the side surface of each of the spikes mounted mounted protruding relative to the side surface of the base, opposite the grate.

Description

Sintering trolley sinter machine.

The proposed utility model relates to the field of ferrous metallurgy, in particular, to equipment for sintering ores and can be used on conveyor-type sintering machines.

The closest to the proposed technical solution for the technical nature and the achieved result, according to the authors, is a sintering trolley of the sinter machine according to the application for the grant of a patent of the Russian Federation 4005167 class Р27В 21/08, dated 02/14/94, publ. 01/27/96 Bull. No. 3, containing a base on which running and load rollers, grates and boards are mounted, consisting of inclined upper and lower parts, the latter of which are provided with longitudinal spikes included in the corresponding recesses of the upper part of the base.

A disadvantage of the known technical solution is the low reliability of the sintering carts caused by warping of the lower part of the sides in the area of the spikes in the corresponding recesses of the upper part of the base. The warping of the lower part of the sides is, in turn, the reason for the increase in the intensity of the leaks in the dash zone, which leads to burning out of the sinter and, as a consequence, to a decrease in its quality. Frequent replacement of sintering trolleys caused by their failure entails stopping the sintering machine, which helps to reduce sinter production.

The task to which the proposed technical solution is aimed is to increase the production and quality of the sinter. In this case, obtaining such a technical result as increasing the reliability of the sintering carts is achieved.

These disadvantages are eliminated by the fact that in a sintering trolley of an agglomeration machine containing a base on which running and cargo rollers, grates and boards are mounted, consisting of upper and lower parts, the latter of which are equipped with longitudinal spikes included in the corresponding recesses: the bases, said recesses are made in the form of enveloping guides such as a dovetail, while the lateral surface of each of the spikes is mounted protruding relative to the lateral surface of the base, opposite to the grate.

A comparative analysis of the proposed technical solution with the prototype shows that the proposed technical solution is distinguished by its structural performance, namely. The shape of the upper part of the base and the location of the lower part of the sides. It follows that the proposed technical solution meets the criteria of the novelty utility model.

A comparative analysis of the proposed solution not only with the prototype, but also with other technical solutions did not allow to identify the essential features inherent in the proposed technical solution. Thus, the proposed combination of natural differences provides the above technical result.

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

On FIG. 1 - shows a General view of the sintering trolley;

Ne tig. 2 - shows a fragment I of figure 1.

The sintering trolley of the sintering machine contains a base I, on the axles 2 of which the running 3 and cargo 4 rollers are mounted. On the base 1, grates 5 and sides are also fixed, consisting of: 53 upper 6 and lower 7 parts. The lower parts 7 of the sides are provided with longitudinal spikes 8 included in the corresponding recesses 9 of the upper part of the base 1, which are made in the form of covering

guides such as. The lateral surface 1C of each of the spikes 8 in contact with the grid-irons 5 is mounted advancing (by the value -c-) relative to the lateral surface 11 of the base opposite the grid-irons 5.

Sintering trolley operates as follows.

The sintering trolley is included in a continuous conveyor belt of an agglomeration machine. As the belt advances, the safety bed and the sinter charge are alternately loaded onto the trolley, which is subsequently subjected to ignition, sintering and, if necessary, cooling.

The implementation of the recess 9 in the form of covering guides such as a dovetail and the placement of the corresponding parts of the longitudinal tongs in them, provides an increase in the rigidity of the sides of the sintering trolleys both when they are loaded with an agglomeration charge and when moving the sintering trolleys, especially on sprockets, which results in an increase in operational reliability of the entire sinter machine.

The execution of the side surface 10 of each of the spikes 8 protruding relative to the surface 11 of the base, increases the length of the path of passage of the sucked-in gases in the instrument area of the rescue trolleys, and also reduces their thermal effect on the upper part of the base and, therefore, on sweeping guides such as a dovetail, which contributes to reduce the intensity of slumps in the dash area of the sintering trolleys, burn out the sinter, increase its quality, increase the operational reliability of the sinter machine, its use the level of performance and sinter production. It is possible to obtain a result. aforementioned technical reIoDMy
