Description

The invention relates to a grille with Einrich for mounting on a grate support and with top cover opening openings for cooling gas.

In the case of coolers for items to be fired from a kiln, for example cement clinker, it is important that as much heat as possible from the refrigerated goods for the furnace process is recovered and that the rust of the radiator withstands the longest possible operating time. Mostly for the thermally highly stressed part of a cooler stationary grate elements known (DE-PS 35 83 059), which a number of support elements with approximately horizontal Air passage arranged predominantly in the direction of conveyance holes exist. For loading drawers with They are not suitable for movable grate plates, and the unwanted rust diarrhea of fine particles can be particularly especially when the cooling air is turned off, do not avoid completely the. - In another known grate element (DE-PS 33 32 592), which should also be suitable for sliding gratings particularly narrow, slanted louvers provided on the back in the conveying direction Side delimited by a sharply tapering profile  are one in a pushing movement towards the goods Would exert peeling or planing action, so that the emp sensitive slot edges would soon be ground and Clinker clog in the slots and clog them would. They also have the disadvantage that they lead to cooling air supply are bound to cooling-air-carrying grate beams that one generally only in high thermal stress Area used and those in the post-cooling area too expensive would be. - The fitting of different grate sections with different grate elements and fastening device is complex.

The invention has for its object to a grate plate create that has high thermal resistance and therefore for the thermally highly stressed area is suitable and connected with an air-guiding grate beam that can be; but also movable in the push area can be arranged and within an open bottom Rust is functional, with rust diarrhea and ver Blockages in the cooling air openings are difficult or impossible are closed.

The solution according to the invention is that on the At least one trough for receiving and Holding refrigerated goods is arranged and the cooling air Passage openings within that of the Chilled area of the trough open.

Since the refrigerated goods held in the trough are opposite the The plate does not move or moves only a little, there is no or there little wear and tear instead. The plate is also in this area in relation to the hot clinker by the detained refrigerated goods isolated.

Advantageously, several troughs are provided to the To be able to hold refrigerated goods more securely.  

According to a special feature of the invention, the Openings (or at least some of them) in side surfaces Chen the trough, which in the operating state essentially are arranged vertically. The passage openings run expediently at least in the area near the mouth falling in the direction of flow to avoid clinker settles in the openings and in the air duct can penetrate richly. In addition, you can do the same Purpose of the openings in relation to the operational Vertical direction be covered, that is, the Plate part located above the opening mouths dominates the one below. This brings with abge switched cooling gas or repair work an additional Security against clinker diarrhea because of the from the clinic pressure applied to the notched bed does not affect the Opening can continue.

To further avoid that the thrust by the Relativbe forces to the clinker forces pushing the openings in will become the opening mouths expediently arranged in the side walls of the troughs, that run parallel to the direction of the relative movement, whereby they are expediently slit-shaped. The cooling gas these openings are then left in the conveying direction fende, hollow ribs fed. Even if this is not the Enjoy protection of an overlying clinker layer they are good due to the cooling air flowing past inside chilled.

In those areas where the plate has a air-carrying grate carrier is connected, it lies on a Top plate of the grate support on its air supply side completely covers. Due to the tight connection between the plate and this top plate of the grate support individual sections of the cooling grate are ventilated separately. It also ensures that all panels are even be supplied with cooling air and thus in clinker bed zones  avoid that the cooling air over the path of the clinker bed least resistance flows through and other areas and Plates are not cooled enough. The underside cover the plate through the top plate of the grate carrier constricts the streams leading further openings arranged cross sections. So that all openings are the same can be flowed through moderately, can be provided according to the invention be that from the cooling gas supply on the underside removed openings have a larger average cross section exhibit than those closer to her.

While the plates in the stationary area just go through Screw connection with the grate carrier top plate can be used in the grate area with bottom open design conveniently attached as this is known from DE-PS 24 32 599. Then there will be all grate plates in the middle or end area of the Cooling zone partly movable, partly immovable above one Air chamber are arranged together with cooling air strikes.

In the moving grate area, in which the grate plates meet overlap partially and movably relative to each other Be certain that during the pushing movement no clinker blown under the overlapping plate can be. Therefore, the cooling gas openings are removed holding troughs expediently only in the non-overlapped Plate part arranged.

The arrangement according to the invention is not only the Plate is spared, but the cooling air emerges from the trough especially due to the sieving effect of the clinker moderately distributed in the upper, hot area of the clinker embeds.  

The invention will now be described in more detail with reference to the drawings explain the advantageous embodiment games illustrated. Show it:

Fig. 1 a longitudinal section carriers by a grate arrangement in the region of two grate plates on stationary grate,

Fig. 2 shows one of Fig. 1 representation corresponding to a movable grate beams,

Fig. 3 shows a cross section through the arrangement of FIG. 1 along line III-III and

Fig. 4 is a side view of a variant of the same grate plate.

According to Fig. 1, on stationary supports 1, the guide channels are formed as air, top boards 2 fixedly arranged, on which grate plates 3 are fixed. The upper plates 2 have peripheral depressions 4 for better connection to the edges of the grate plates and are screwed to the grate plates.

The grate plates 3 overlap in the area 5 and are provided with a seal 6 there . In the exposed area, they contain troughs 7 , which are formed by transverse ribs 8 and longitudinal ribs 9 . Cold chilled goods are firmly held in them, which forms a protective cover against the hot chilled goods located above them.

In the side walls 10 of the troughs 7 there are cooling gas through openings 11 which run a little falling in the direction of flow in order to make it more difficult for cooling air to pass into the interior of the plate to the gas supply area. They are slit-shaped in the longitudinal direction of the grate or in the direction of movement of the material. The part 12 of the ribs 9 located above the slots 11 protrudes further beyond the mouths of the slots 11 into the trough 7 than the part 13 located below, so that the mouth of the passage openings 11 is covered.

Air guide channels 14 are provided under the ribs 9 . Furthermore, the trough floors 16 form a certain distance from the top plate 2 of the grate carrier, so that an air-guiding intermediate space 15 is formed between them. To compensate for the flow resistances in the air duct areas 14 , 16 , the slot 11 'in the foremost depression (far right in Fig. 1) is formed further than the slot 11 ''in the middle depression and this in turn further than the slot 11 ''' in the rearmost depression, which is closest to the air-carrying grate support 1 .

While Fig. 1 shows a stationary grate plate assembly illustrated FIG. 2 is a corresponding arrangement in a reciprocating grate. In a known manner change with fixed, air-guiding grate beams 1 movable grate beams 1 ', which are driven back and forth in the direction of the arrow in the longitudinal direction of the grate. The front edge of the associated grate plate 3 takes the dash-dotted lines at 3 ' and 3'' indicated extreme positions. So that in no operating condition a trough of the plate shown on the right Darge gets under the left plate and thereby refrigerated goods can be blown under the left plate, the troughs 7 are limited to that area that is always outside the overlap area. Otherwise, the grate plate arrangement of FIG. 2 is the same as that explained with reference to FIGS. 1 and 3.

Without air-guiding grate supports 1 and without their top plate 2 , grate plates of the type shown in FIG. 1 or 2 can also be used in the grate area in which the cooling gas is not supplied individually for each grate plate row by air-guiding grate supports 1 . The grate plates can then be fastened in a suitable manner without the grate support top plates 2 . For this purpose, one advantageously uses the fastening elements illustrated in FIG. 4, which are known per se, for further explanation of which reference can be made to the prior art (DE-PS 24 32 599).
