Description

[Detailed description of the invention] This invention relates to a device for cooling a high-temperature sintered ingot and recovering the heat of the sintered ingot, and in particular, it is a device that prevents the sintered ingot from getting caught in the gaps formed between each grate plate. Relating to a mass cooling device.

Figure 1 shows the structure of the burning arm cooling device. In the figure, a baked ingot 8 of cement clinker or the like discharged from a baking device 1 such as a rotary kiln falls onto a grate 5 disposed within a device body 3. The grate plate 5 is constructed by alternately arranging a movable plate 5a that reciprocates along the baked ingot transfer direction X by a drive device 6 and a fixed plate 5b fixed at a predetermined location. As a result, the baked ingots that have fallen onto the grate plate 5 are gradually transferred toward the discharge port 10 by the movement of the movable plate 5a. On the other hand, cooling air is supplied to the air chamber 7 by a fan 11, and this cooling air passes through the baked ingot layer through small holes formed in each standard width plate 5a, 5b to cool the baked ingot. A part of the air heated by heat exchange with the baked ingot is used as combustion air for the burner 2 provided in the baking device 1. FIG. 2 is a plan view of the grate plate, and FIG. 3 is a side view of the grate plate. The gaps 16 formed between the plates are also continuous so as to be located on a straight line. Furthermore, Figure 4,
As shown in FIG. 4A, which is a needle perspective view, this gap 16 continues even toward the air chamber 7 side, that is, toward the direction of gravity. As a result, the baked ingot gets caught in this gap 16, especially the part 16a shown in FIG. A large amount of baked ingots will also fall into the air chamber 7.

The purpose of this invention is to eliminate the above-mentioned problems and provide a baked ingot cooling device configured to reduce the occurrence of baked ingots being caught in the ingot and falling into the air chamber.

In short, this idea prevents the gaps formed between the plates from continuing in a straight line by arranging the plates in a staggered manner, thereby preventing baked ingots from getting caught and falling into the air chamber. The object of the present invention is to provide a baked ingot cooling device that allows for the cooling of baked ingots.

Examples of this invention will be described below.

Figures 5 to 7 (Figure 7A is a perspective view)
, the fixed plate 5b and the movable plate 5a
are arranged alternately in the conveying direction Among them, every other plate is made into a wide plate 5b'. On the other hand, each movable plate group is left in the same shape as the conventional one. As a result, the gaps 17 formed in the fixed plate group are no longer continuous with the gaps formed in the movable plate group, and the gaps are arranged in a staggered manner in the entire great plate 5. With this configuration, the gap not only becomes discontinuous with respect to the conveyance direction X of the baked ingot, but also becomes discontinuous in the direction of gravity as shown in FIG. Therefore, the occurrence of baked ingots getting caught in each gap and falling into the air chamber is greatly reduced. Note that in the above case, the wide plate is arranged within the fixed grating plate group, but the same effect can be obtained even if the wide plate is disposed within the movable grating plate group.

By implementing this idea, the gaps formed between each plate can be discontinuous in an almost staggered arrangement, which greatly reduces the amount of baked ingots caught in the gaps and the amount of baked ingots that fall into the air chamber. can be done.

Claims (1)

[Claims for Utility Model Registration] 1. A grate is formed by arranging movable plate stages and fixed plate stages alternately in the baked ingot transfer direction, and the baked ingots on the grate are reciprocated by the reciprocating movement of the movable plate steps. What is claimed is: 1. A baked ingot cooling device for transferring and cooling a baked ingot, characterized in that side gaps between the plates are formed in a staggered arrangement in the transfer direction. 2. In the sintered ingot cooling device according to claim 1 of the utility model registration claim, one of the movable plate stages and the fixed plate stage is formed only with standard width plates, and the other stage is formed with wide plates. Formed by alternating standard width plates.
