Description

The invention is intended to provide a water screen for cooling the grate by placing a tubular system between the moving grate, connected to or to the boiler and representing the element circulating for water, or to the water supply supplying the boiler with water.

In FIG. 1 shows a longitudinal section of a grate; Fig 2 is a view of a modified grate; FIG. 3 is a cross section of it; FIG. 4 is a longitudinal (view of another modification of the grate; Fig. 5 is a vertical section of the grate in another form of embodiment; Fig. 6 is a cross-section of it; Fig. 7 is a top view of it; Fig. 8 is a vertical section of its modification; Fig. Fig. 9 is a cross section of a modification of the lattice; Fig. 10 is a top view thereof.

The lattice is a combination of moving grates 8.9 and a tubular system I, 2, S, which consists of boxes I, 2 (Fig. 1 and 2) with tubes 5 rolled into them, supported on supports 4, 6, 11 Til brick masonry the rear wall of the boiler, on the one hand they are fixed and when heated, the boiler can freely expand to the other not fixed side.

This system is either connected to the boiler as a circulating element for water.

or is included in the water supply system that feeds the boiler with water. Between the pipes S of the system I, 2, 3 are placed the lattice-forming box-shaped, open at the bottom, serrated on top and equipped with gaps for air passage, the grate bars, each of which consists of two parts 5 and P, the first of which is in the furnaces with a front furnace (Fig. 1 a) the front end moves only progressively along the roller 5 mounted on the support 4, and the rear end is connected with the transverse beam 10, which can receive close to circular ones from the corresponding movement mechanism; the second part 9, with its hooked front end, is connected to the protrusion 13 of the first part 5, while its second end lies on the rollers 5 placed in the slots 4, whereby it makes free translational movements. In the absence of a front furnace 8 front furnace 8 in the fire grate, placed under the feed hopper lying on support 4, movements, similar to its rear end, are close to circular movements (Fig. 2). In the furnace shown in FIG. 4, the portions 5 and S of the grate are supported by a cross member 10 provided with support sockets for the rear end 15 of the part 8 and the front end 14 of the part 9 of the grate. In the case of very long furnaces between parts 5 and P of the grate, an intermediate

The region, which, like the ends of the first two parts, is associated with movements that are close to circular.

FIG. 5-7 depicts a grate bag consisting of parts of the i4 spikelets, which are integral or rigidly attached to each other, and which are connected to the farms and, with their hind ends, freely pots on the crossbar D; These grates A, together with the farms I, with the help of an eccentric G, make reciprocating movements in the grooves of the crossbars Ж 3. Between the grate A, like the previous one, there are circulating pipes designed for cooling the grate bars.

The grate shown in FIG. 8-10, refers to the formation of fuel boxes, for which the grate B with circulation pipes placed between them is placed in groups, between which the additional pores A of the circulation system are located along the U-shaped contour. These pipes And in the vertical parts of the above circuits are installed close to each other, have horizontal holes in the horizontal for air passage, and in the rear part of the furnace are lowered to the level of the pipes running between the grate bars.

The subject matter of the invention.

Claims (6)

1. A mechanical grate, characterized with the use of a tubular system, (2, 3) (figs. 1, 2, and 3), connected to or with a boiler, as an element circulating for water, or connected to a water supply network with tubes 3 with box-like open bottom, serrated on top and provided with gaps for air passage by the grate bars, each consisting of two parts 5 and S (Fig. 1), of which the first, in the furnaces with a pre-furnace, the front end moves only progressively over the support 4 and the rear end is connected to the crossbeam 10, which may receive from the corresponding mechanism of movement, close to circular, the second 9 is connected by its front end with the first part by means of a protrusion 13 on one and the hook that responds to it — to the other, while the rear end moves only progressively along support 4, 2. The grid variation according to claim 1, characterized in that the grate bars therein are composed of three or more parts, the middle of which are connected to the outermost and between each other using the joint described in paragraph 1 for parts 5 and S, and the joints these are reported movements that are close to circular. 3. Modification of the grate according to claim 1 with the absence of a pre-furnace in the furnace, characterized in that the front end of part 8 of the grate (FIG. 2), placed under the hopper, is provided with a support 4, which, as well as its rear end 10, communicate close to circular. 4. Video grid change according to claim 1 and 2, characterized in that instead of directly connecting parts 8 to 9 (figs. 1 and 2) of the grate with each other, supporting these parts 5 and S (fig. 4), the cross member 10 has separate support sockets for the rear end 15, part 8 and the front end 14 of the part 9 of the grate. 5. Lattice change according to claim 1, characterized in that the rear end resting freely on the crossbar D is one piece or composed of parts of the grate A, rigidly fastened with each other, are connected with the farms I and receive together with them from the eccentric G the movements in the grooves of the crossbars G vi 3 (Fig. 5). 6. Variations in the lattice according to claim 5, different. by the fact that grate B (Fig. 8, 9 and 10) with circulating tubes placed between them are placed in groups and between these groups are included additional pipes A of the circulation system arranged in a U-shaped contour, which are installed in the vertical parts of these contours close to each other in order to form above the grid bars groups of fuel boxes, there are openings in the horizontal part for air passage, and in the rear part of the furnace tube the U-shaped groups are lowered to the level of the tubes running between the grid bars. to the author's certificate B. fig.Z.
