With respect to the grate track separating element that is positionedly fixed and placed between the two grate trucks of the gate), the grate track separating element is installed in the grate track of the feed grate. , In each grate bar row adjacent to the grate track separation element in the vertical direction (feed direction) of the two grate tracks adjacent to each grate track separation element, in each case one first A grate bar mounted in a fixed position and a related second grate bar placed on the upper support surface of the first grate bar are arranged and related to the second grate. The rod is attached so that the second grate rod can slide with the feed motion on the upper support surface of the first grate rod, and the grate track separating element is the cast part as a cast part. Formed with a tubular conduit that allows water to flow through, which is formed in the wall of the cast part during casting.

The present invention further comprises a grate truck formed in steps from individual grate bars arranged in multiple columns and rows and oriented in an inclined manner, especially a feed grate incinerator for grate incineration. A central beam formed from a number of individual grate track separation elements arranged in a fixed position and aligned with each other is formed between the two grate tracks. One grate track comprises multiple columns and rows of grate bars, each vertically adjacent to the grate track separation elements of the two grate tracks, one in each case. The first grate bar mounted in a fixed position in the first position and one related second grate bar are arranged in a complex manner, and one related second grate bar is fed. Attached to allow movement and sliding with feed motion on the upper support surface of the first grate bar while the second grate bar is placed on the support surface. Each grate track separating element is formed as a cast part, together with a tubular conduit that allows water to flow through, which is formed in the wall of the cast part during casting of the cast part.

The okuribi grid is, in particular, a component of the okuribi grid incinerator of a grate incinerator. The okuribi grate is an incineration grate of a grate incinerator, generally consisting of multiple grate trucks and arranged in an inclined manner. Combustion waste is input into the incineration grate at one end and reaches the other end. Be transferred. Garbage is incinerated on the path from the input end to the output end. Each grate track is for a first positionally fixed grate bar and the first grate bar that form one laterally running row (row) in each case. It is alternately composed of a second grate bar capable of performing a sliding motion and sliding along the first grate bar. In this case, all grate bars attached to be able to perform feed motion are such that the grate bars are evenly moved on the first row of grate bars placed beneath the grate bars. Placed in. In this regard, each row of second grate bars mounted to allow for feed motion moves uniformly. On the other hand, the grate bars are all formed with the same width, thus forming a column that is uniform over the length of the grate track in the vertical direction of the grate track and is fixedly attached to the column. A first grate bar and a second grate bar attached so as to be able to perform a feed motion are alternately arranged back and forth in each case. Garbage is transferred from the input side of the feed grate to the opposite side by a uniform back-and-forth movement of the individual rows formed from the second grate bar mounted to allow feed movement. Constructing the feed grid to form an incineration grid, among other things, each grate bar has an outlet slot for incinerated air that hits the grate bar from below on at least one of the outer surfaces of the grate bar. It will be achieved by that. After the initial ignition of the waste, the incineration air hitting from below ensures continuous incineration of the waste located on the grate truck.

This type of okuribi grate is preferably used for incinerating waste, but it is also possible to incinerate biomass or so-called substitute fuels such as plastic waste, or a mixture of specified fuels.

Since the grate truck expands due to the action of heat during incineration, but contracts again when the feed grate of the okuribi incinerator is out of service, each grate truck has at least one longitudinal grate track. Arranged so that it can be inflated on the directional side. In the case of a two-track okuribi grate or a okuribi grate with multiple grate tracks arranged adjacent to each other in a two-track configuration, a grate track composed of grate separation elements arranged in a fixed position. The grate track separator is also called the central beam because the separator is formed in the center between the two grate tracks. To make the grate track separator sufficiently heat resistant, it is known that the grate track separator is formed as a cast part that can be cooled using water. In this case, a tubular conduit through which water can flow is formed in the wall of the element during the casting of the cast part. This type of grate track separator is generally arcuate, like an inverted U. Due to the casting technology, it is necessary to equip both a feeder to supply the melt to the cast part that is completely wrapped in the mold as a whole and a riser to allow air or gas to escape and contain the excess melt. It is not possible to produce any desired shape, and in particular, this U-shaped grate track separating element cannot be produced in any desired relative spatial position. This has the consequence of creating isolations or cavities within the walls of such grate track separation elements. During operation, this means that during use, the cavities present will dissipate heat from the outside of the grate truck separation element to the headrace cooling pipe inside the grate truck separation element. It has the effect of hindering. This leads to local overheating of the wall material and splitting of the wall. Therefore, this type of grate track separating element has a useful life of up to about one year of operation.

Therefore, there is a demand for alternative designed grate track separators that can be cast more effectively.

The present invention is based on the object of providing a solution that makes it possible to provide a grate track separating element that can be effectively cast with improved fit of the grate bar to the geometry of the feed grate. There is.

Thanks to the flat support surface of the grate track separation element provided in one embodiment and the thickness and height according to the invention, this is no longer a biomass or substitute fuel between two grate trucks or fuels thereof. Does not cause separation obstacles to the movement of the mixture of waste. In this case, the useful life of the element can further deposit debris or substantially the above fuel on this flat support surface during operation of the okuribi grate, and the combustion of the debris or fuel will separate the grate track. It can be better affected by not being struck by the air coming out of the element directly, because the grate track separation element is formed without an air outlet slot. In this regard, in this operating situation, the debris / fuel forms a lining that protects the surface of the grate track separation element from the excessive action of heat. Further, according to the embodiment of the grate track separating element according to the present invention, the component can be effectively produced as a cast part in molten steel, in particular, at the base of the grate track having a conduit, so that the component is in the wall region thereof.

It can be placed on an upper flat support surface. The form of the grate bar carrier receiver allows the grate track separator to be placed and mounted on a conventional grate bar carrier that resides within the grate track of the okuribi grate. In particular, in this case, a round bar may be preferably used. The grate track separation elements have the same height as the two grate bars stacked in sequence, and the length of the upper flat support surface corresponds to the movement stroke of the grate bars that can perform the feed motion. The geometric design of the grate track separator is a completely compact shape sized so that the grate track separator can be treated as an individual component and as an individually interchangeable component.

It is particularly suitable when it is equal to the sum of the height of one grate bar and the height of the second grate bar. Specifically, especially when the level of the top flat support surface of the grate track separation element is equal to or at least substantially equal to the level of the top support surface of the second grate bar adjacent to the grate track separation element. Suitable, the second grate bar is located at the installation position of the second grate bar, which is placed on the upper support surface of the first grate bar to which the second grate bar is associated. ing. In this way, it is possible that fuel, especially debris, can be moved or transported from the grate track adjacent to the grate track separation element onto the upper flat support surface of the grate track separation element. The first grate bar and the second grate bar can have different heights or thicknesses, but the first grate bar and the second grate bar have the same height or thickness. It is particularly suitable when it is formed by. Thus, the feed grate is a first, depending on whether the grate bar is located and mounted on a grate bar carrier capable of feeding motion or on a positionally fixed grate bar carrier. Equipped with only one grate bar type that can be made to constitute a grate bar mounted in a fixed position or a second grate bar attached to allow for feed motion. Is possible.

In the case of, as shown in FIG. 2, it is shown that the grate track separating element and the first grate bar and the second grate bar indicate the relative positions with respect to each other.

FIG. 1 shows a feed grid incinerator represented by 1 as a whole of a feed grid incinerator of a grate incinerator. The feed grid 1 has a two-track configuration, has two grid tracks 2, only one of the two grid tracks 2 is shown, and the other second grid track has the same structure. It is located within the free grate track area 2'in the figure. The two grate tracks 2 are centered in the center of the okuribi grate 1 with respect to the width of the okuribi grate 1 by a grate track separator 3'formed in a fixed position consisting of individual grate track separation elements 4'. And they are separated from each other in half. Each grate track 2 has a large number of columns 5 and 6. The columns 5 and 6 are formed from a first grate bar 7 and a second grate bar 8 that are individually arranged adjacent to each other. The first grate bar 7 is a grate bar attached in a fixed position, and the second grate bar 8 is a grate bar attached so as to be able to perform a feed motion. The grate bar 8 is placed on the upper support surface 9 of the first grate bar 7, and the grate bar is placed between the front end position and the rear end position of the front upright face surface 10 of the grate bar. It slides on the upper support surface 9 with the feed motion so that it can cover the movement stroke V. Thus, the column 5 comprises a large number of first grate bars 7 and second grate bars 8 arranged so as to be at least substantially aligned with each other in the vertical direction L, alternating in each case. A first grate bar 7 mounted in a fixed position and a second grate bar 8 placed on the first grate bar 7 are arranged, and the second grate bar 8 is a second grate bar 8. The upper support surface 11 of the second grate bar 8 adjacent to the bottom surface, which is attached so that the grate bar 8 of 2 can slide with the feed motion, is now arranged on the first grate bar 7. A first grate bar 7 is also mounted on top, followed by a second grate bar 8. This design creates a stepped, diagonally rising grate surface of each grate track 2 from the emission side A to the input side B of the feed grate 1. The stepped shape is formed by superimposing the first grate bar 7 and the second grate bar 8 in order and arranging them alternately.

The row 6 is formed of grate bars located adjacent to each other in the lateral direction Q of the okuribi grate. In this case, each row may be fed to one type of grate bar in each case, i.e., a first grate bar 7 exclusively positioned or mounted in a fixed position. Consists of either of the second grate bars 8 attached to, and therefore stationary rows and rows attached to allow for feed motion are formed alternately over the length of feed grate 1. .. The transfer of waste to be incinerated on the feed grid 1 from the input side B to the discharge side A is the feed motion, that is, the front end position of the second grate bar 8 attached so as to be able to perform the feed motion. It is performed by a forward movement to the rear end position, a backward movement to the rear end position, and a forward movement to the front end position again. The combustion air required for burning the waste hits a large number of the first grate bars 7 and the second grate bars 8 from the bottom, and burns from the air outlet slots 12 formed on the upper support surfaces 9 and 10. It comes out as air.

The feed grid 1 shown in FIG. 1 described above is according to the present invention in that the grate track separator 3'formed as the central beam 13 is simply formed from the grate track separating element 4'according to the prior art. It is different from the okuribi grid. These positionally fixed, arranged and mounted grate track separating elements 4'are tubular as cast parts, which are formed in the wall of the cast part during casting of the cast part and are capable of allowing water to flow through. Together with the conduit, it is formed in an inverted U shape in a known manner and, as can be seen from FIG. 1, protrudes from the surface of the grate track formed by the first grate bar 7 and the second grate bar 8. Only this grate track separator 3'is replaced by the grate track separator 3 formed from the grate track separating element 4 according to the present invention in the case of the feed grate 1 according to the present invention. All other elements correspond to the elements and components shown in FIG. 1 above. The lateral Q expansion capacity of the individual rows 6 is not by the central grate track separators 3, 3', but rather by bearings on the longitudinal flanks located on either side of the feed grate 1 (not shown in further detail). ).

The grate track separator 3 formed from the grate track separating element 4 according to the present invention of the okuribi grate 1 according to the present invention will be discussed in detail below based on FIGS. 2 to 9.

FIG. 2 consists of a grate track separating element 4 removed from the grate track 2 and a first grate bar 7 and a second grate bar 8 arranged adjacent to the grate track separating element. In the form of a group, they indicate their relative positions and installation positions relative to each other at their respective installation positions within the grate track 2 of the feed grate 1. In this regard, the figure shows the first grate bar 7 and the second grate bar 8 and the grate bars 7 and 8 in the grate track 2 of the feed grate 1 separated from the grate track 2. It is explanatory drawing of the group consisting of the grate track separation element 4 in the installed state.

A first grate bar 7 fixedly arranged on the ground and a second grate bar 8 attached so as to be able to perform a feed motion are assigned. In this case, on the left-hand side of FIG. 2, all the second grate bars 8 capable of performing the feed motion are behind the second grate bar 8 on the front upright face surface 10 of the second grate bar 8. The second grate bar 8 located on the right-hand side opposite to that shown at the end position is on this side the front upright face of the second grate bar 8. The rear end position and the front end position shown in the front end position of the second grate bar 8 on the surface 10 are shown by each second grate bar 8 capable of performing a feed motion. A movement stroke V is defined to cover during the feed motion of the grate bar 8 from the rear end position of the grate bar 8 to the front end position of the grate bar 8 and back to the rear end position of the grate bar 8.

For example, as can be seen from FIG. 4, which shows the row of the first grate bar 7 and the second grate bar 8 shown on the right side of the grate track separation element 4 in FIG. 2 together with the grate track separation element 4. In the view toward the left hand side of the grate track separation element 4 of FIG. 2, the first grate bar 7 and the second grate bar 8 are in a state of being removed on the left hand side, and each grate track separation. The element 4 has a flat support surface 15 on its upper surface and an upright face surface 16 in front of the feed direction of the feed grid 1. On the bottom surface, each grate track separating element 4 has a front support surface 17 adjacent to the front upright face surface 16 and a rear grate bar carrier receiving portion formed like a recess separated from the front support surface. It has 18. Each grate bar separation element 4 uses the front bearing surface 17 at the bottom of the grate bar separation element 4 to be the next grate track separation element adjacent to the grate bar separation element 4 on the front side in the vertical direction L. It is placed on the flat support surface 15 of 4. The upper flat support surface 15 has a length L1. The length L1 is such that the second grate bar 8 is placed on the upper support surface 9 of the first grate bar 7 adjacent to the second grate bar 8 on the front side in the vertical direction L. It is at least equal to the length L2 covered as the movement stroke V during the feed motion between the front end position and the rear end position of the front upright face surface 10 of the grate bar 8 of 2. These lengths and length ratios are specifically shown in FIG. The total length L4 of the grate track separation element 4 is from the front face edge of the first grate bar 7 to which the grate track separation element 4 is fixedly fixed to the support surface 9 of the first grate bar 7. It is at least as long as the length L3 extending to the front upright face surface 10 of the second grate bar 8 attached so that the feed motion can be performed. Preferably, the full length L4 is still sufficient for the adjacent grate track separating element 4 at the rear end position of the upright face surface 10 of the second grate bar 8 attached to allow feed motion. Sufficient residue at this position with the upper support surface 11 of the second grate bar 8 and the upper flat support surface 15 of the grate track separating element 4 that abuts adjacent to it in order to form a good lateral contact surface. It is configured to be 10-20% longer than the length L3 to form the overlap. These length ratios of L4 and L3 can be seen particularly from FIG. 3, in which the grate track separating element 4 shown in FIGS. 2 and 4 is shown in FIG. Shown in a perspective view seen from the left-hand side, the rows of the first grate bar 7 and the second grate bar 8 are arranged on the left-hand side of FIG. 2 in front of the grate track separation element. In this case, the length L1 of the upper flat support surface 15 of each grate track separating element 4 is relative to the upper support surface 11 of the second grate bar 8 attached so as to be able to perform the feed motion. It may be formed to have the same length, or it may be formed to be shortened depending on the length L2 of each formed movement stroke V.

The first grate bar 7 and the second grate bar 8 are preferably geometrically identical in shape, so that any of these grate bar elements were mounted in a fixed position. Both the grate bar 8 and the grate bar 7 can be used as a first grate bar 7 or as a second grate bar 8 attached to allow feed motion.
