動において問題が生じる。 Known devices of this type (German Publication No.
No. 1608018), the individual grate wheels are fixed to an external annular support driven by drive rollers. To empty the grate car, the grate car is tilted downwards by lowering the internal running rails. However, problems arise in evacuation, thermal expansion and actuation.

く摩損させられる。 That is, in large-scale plants, driving via an external annular support requires complicated and time-consuming design due to the large diameter of the support and its required rigidity. Anchoring of the grate wheels in external supports necessitates undesirably large dimensions of the circumferential expansion gap, since radial expansion reduces the circumferential expansion gap between the two grate wheels. There is. Also, the emissions from inside the individual grate wheels are not satisfactory.
The grate wheel must be lowered over its entire length and raised again through a long sweeping distance. Since the angle of inclination is limited by friction and strength, a long evacuation path is required. Therefore, the reactive surface of the process will be lost. Additionally, all the material slides down the inside sides of the grate wheel, causing significant wear and tear.

場合である。 Additionally, various other solid material heat treatment apparatuses are known. This includes belt-type sintering equipment, which comprises a steel structure in which a number of grate wheels forming a moving grate in the form of a continuous belt are guided on running rails with the help of a lifting mechanism. . However, belt sintering devices of this type have the disadvantage that only about 40% of the grate surface is used as reaction surface, and 60% of the grate surface runs unused. In a combustion device with a short distance, the ratio of the reaction surface to the wasted surface becomes even larger, which is undesirable. Another disadvantage of this belt sintering apparatus is due to the fact that as the length and width increase and the associated speed of the belt increases, significant wear and tear occurs. For example, a belt sintering device with an effective suction surface of 500 m 2 and a grate wheel width of 5 m is operated at a speed of 10 m/min for sintering ore during a sintering period of 10 minutes.

% can be used for heat treatment of solid materials. However, these circular sintering devices have three basic structural features, namely circular hearth drive, thermal expansion regulation, and evacuation, all of which cannot be satisfactorily addressed by known circular hearth designs. Conventionally, its uses were limited,

い。 Pelletizing combustion devices are also known which consist of a circular hearth with a water-cooled closed grate surface. Evacuation from this grate is carried out by means of a bucket excavator. As a result, the grinding produces fine substances that block the gas passage holes between the grate bars and affect the progress of the process. This water-cooled pelletizing combustion equipment requires a large amount of cooling water, and the transportation of the cooling water, the supply and discharge of the cooling water, the treatment of the cooling water, and the re-cooling of the cooling water cause high costs. , which is not interesting from the point of view of economical processing of bulk solid materials, especially fine-grained iron ore.

ことにある。 The object of the invention is to avoid the disadvantages of the known devices and to ensure a better solution of the thermal expansion problem and at the same time a problem-free evacuation of the grate wheel, a favorable arrangement of the drive of the mobile grate, as defined at the outset. The objective is to provide a device that

れていることを特徴とする固体材料熱処理装置に
より達成される。 According to the invention, the object consists of a rotatable support and a number of segmented grate wheels which are tiltably mounted on the support and form an annular moving grate, each grate wheel being a solid body. It is tiltable about an axis passing through the conveying surface of the moving grate for material discharge, and the support 1 is arranged only inside the ring of the moving grate, and the grate wheel 3 moves annularly on its inner end side. attached to said support 1 so as to be tiltable about a radially extending axis of the grate;
This is achieved by a solid material heat treatment apparatus characterized in that its outer end is supported by support rollers 7 on a fixed guide path 8 provided outside the ring of the movable grate.
前記支持体に移動火格子のリング内側に配設さ
れたレールＳ上を走行する走行ローラＲを設け、
環状移動火格子のリング内側に配設された駆動手
段２１，２２により駆動するようにするのが好適
である。 A running roller R running on a rail S disposed inside the ring of the movable grate is provided on the support body,
Preferably, it is driven by drive means 21, 22 arranged inside the ring of the annular moving grate.
本発明に係る装置により次の利点が得られる。 The device according to the invention provides the following advantages:
すなわち、本発明に係る装置の内側に配設され

り小さく、また建造がより容易であり、このため
摩擦駆動の利用あるいは環状支持体の中心軸でも
つてシヤフトを介しての強制直接駆動の利用が可
能である。 That is, the annular support arranged on the inside of the device according to the invention is smaller and easier to construct than the one arranged on the outside, which makes it easier to use a friction drive or to use an annular support. It is also possible to use forced direct drive via a shaft on the central axis.
熱膨張は火格子環の内側での火格子車の取付け
により、外側での取付けよりもより容易に制御す
ることができる。 Thermal expansion can be more easily controlled by mounting the grate wheel inside the grate ring than by mounting it outside.
従つて、本発明に係る装置は膨張条件の点から

環の内側での取付けのため、個々の火格子車間の
半径方向の膨張間隙は所望なだけ広げられる。従
つて、膨張間隙をより小さな寸法にすることがで
きる。 The device according to the invention is therefore also more efficient in terms of expansion conditions than the known one. Due to the mounting inside the ring of grate wheels, the radial expansion gap between the individual grate wheels can be widened as desired. The expansion gap can therefore be made smaller in size.
大きな利点は、火格子車の半径方向の縦軸のま

短いことにより全表面に対する反応面の比がさら
に改善される。 A major advantage is the simple evacuation of the individual grate wheels around the radial longitudinal axis of the grate wheels. Since the center of gravity axis of the grate wheel substantially coincides with the above-mentioned axis, it is possible to discharge with a small force by simply tilting the grate wheel around the center of gravity axis without turning or lifting it. Furthermore, since only half of the length of the grate wheel needs to be tilted upward and downward at the same time, the discharge path is very short. The short evacuation path further improves the reaction surface to total surface ratio.
本発明に係る装置の安定性は、環状または円盤
状支持体を箱形断面あるいは骨組のように設計す

がある。 A particularly advantageous variant of the invention, taking into account the particular kinematics of the moving grate, is that the support pins provided inside the ring of the moving grate are mounted by means of telescopic bearings and pendulum bearings that prevent movement in the circumferential direction.
