2. Description of the Related Art Generally, a dry incinerator has a structure as shown in FIG.

Reference numeral 1 in the drawing denotes a casing, which constitutes the outer shell of a dry incinerator and forms a drying chamber 1A inside. The inside of the drying chamber 1A is maintained in a dry state at a high temperature by a burner (not shown). Further, the turntable 3 described later is also heated. At this time, it is dried or incinerated depending on the degree of heating.

On one side of the casing 1, there is provided a charging port 1B for charging a material to be dried to be burned from the outside.
A rotary shaft 2 is provided in the center of the casing 1, and a turntable 3 is provided on the rotary shaft 2. The turntable 3 is provided with a charging port 3A for dropping the material to be dried placed on the upper surface thereof downward. The turntable 3 is set to rotate counterclockwise in the figure.

On the upper side of the turntable 3, there are provided four baffle plates 4 for spreading the material to be dried that has fallen on the upper side surface of the turntable 3. Each baffle plate 4 is fixed to the casing 1. Of the four baffle plates 4, the most downstream baffle plate 4A is closest to the upper side surface of the turntable 3, and all the non-dry matter on the upper side surface of the turntable 3 is scraped off from the charging port 3A. Drop it down.

With the above-described structure, the material to be dried, which has been charged into the drying chamber 1A through the charging port 1B, falls between the most downstream side baffle plate 4A and the most upstream side baffle plate 4B. Combustion material to be dried that has fallen onto the upper surface of the turntable 3 is accompanied by the rotation of the turntable 3 and the baffle plate 4 on the most upstream side.

[0007]

In the dry incinerator having the above structure, ideally, the material to be dried is sequentially spread by the three baffle plates 4 having the baffle plate 4B on the most upstream side at the top. Finally, they are finally collected by the baffle plate 4A on the most downstream side and dropped downward from the charging port 3A. However, in the dry incinerator, since the charging port 3A also rotates together with the rotation of the turntable 3, the charging port 3A is located between the most downstream baffle plate 4A and the most upstream baffle plate 4B. There are also things to do. In this case, the material to be dried in the form of lumps that has been charged from the charging port 1B or the material to be dried in a solid state before being spread by the baffle plate 4B on the most upstream side directly enters the charging port 3A. Will fall downward.

Of the baffle plates 45 of the book, the baffle plates 45B and 45D on the most upstream side and the most downstream side have sawtooth-shaped portions facing the upper turntable 26, as shown in FIGS. . As shown in FIG. 4B, the intermediate baffle plate 45C has a flat surface at the portion facing the upper turntable 26. The gap between each baffle plate 45 and the upper side surface of the upper turntable 26 is appropriately set. Preferably, the upstream gap in which the material to be dried is present as a relatively large mass is set large, and the downstream gap is set small. This allows
The material to be dried, which has been injected as a relatively large lump from the charging port 30, is spread to a certain extent by the baffle plate 45B on the most upstream side having a large gap with the upper turntable 26, and a large number of serrated cross sections are formed on the surface. The intermediate baffle plate 45C spreads it wider and the surface is flattened, and the most downstream baffle plate 45D spreads it over the entire surface of the upper turntable 26 and has a serrated cross section. Make a number of grooves. That is, the three baffle plates 45 uniformly spread the material to be dried on the upper side surface of the upper turntable 26 to widen the area for drying or incineration, and to form a large number of grooves having a serrated cross section or a flat surface. The material to be dried is uniformly or efficiently dried or incinerated by forming it into a shape or stirring it.

The guide plate 46 is formed in such a manner that it gradually increases from the rotary shaft 28 in a substantially spiral shape (a left-handed spiral shape in FIG. 2) and extends to the casing 25 of the dry incinerator 11, and the upper side thereof. The material to be dried placed on the upper surface of the turntable 26 is scraped and guided to the outer peripheral edge. This guide plate 46 is used for the casing 2 of the dry incinerator 11.
It is fixed at 5. As shown in FIG. 4D, the guide plate 46 is formed in a flat shape on the upper turntable 26 side. The guide plate 46 and the upper turntable 26
The gap between the upper side surface of the upper turntable 26 and the upper side surface of the upper turntable 26 is narrow enough to guide all the dried or burned combustibles to the outer peripheral edge of the upper turntable 26. Desirably, it is set to be smaller than the particle size of the material to be dried.

The structure of the baffle plate 48 of the lower turntable 27 shown in FIG. 3 is similar to that of the baffle plate 45 of the upper turntable 26. The structure of the guide plate 49 is the same as that of the guide plate 46 of the upper turntable 26. In the case of a material to be dried which has a property that the particle size is reduced by drying or incineration on the upper turntable 26, the gap between each baffle plate 48 and the guide plate 49 and the upper side surface of the lower turntable 27. Is the upper turntable 2
It is set smaller than the case of the baffle plate 45 and the guide plate 46 on the 6 side. The guide plate 49 on the lower turntable 27 side is set slightly upstream of the guide plate 46 on the upper turntable 26 side. As a result, the guide plate 46 on the side of the upper turntable 26 causes the burned material to be dried on the guide plate 4 on the upper side surface of the lower turntable 27.
It is designed to fall slightly downstream of 9.

Below the lower turntable 27, FIG.
As shown in, a plurality of blades 51 are attached. This 51 scrapes up the material to be dried, which has fallen on the bottom surface of the dry incineration chamber 11A, and drops it from the discharge port 52 to the screw conveyor 39.

The dry incinerator 11 configured as described above
Then, the material to be dried which has been introduced into the dry incineration chamber 11A from the automatic transfer device 13 through the input port 30 is the guide plate 4
6 and the baffle plate 45B on the most upstream side, and falls to the baffle plate 45B side as the upper turntable 26 rotates. Then, the baffle plate 45B is widely spread and at the same time, a large number of line grooves having a serrated cross section are formed.

In this way, the material to be dried which has passed through the baffle plate 45B on the most upstream side reaches the intermediate baffle plate 45C, which is further widened by the baffle plate 45C and a large number of streak grooves are formed. The formed surface is flattened.

The material to be dried, which has passed through the intermediate baffle plate 45C and has been spread widely and leveled to a flat surface, reaches the most downstream baffle plate 45D and finally reaches the upper side by this baffle plate 45D. The turntable 26 is spread over the entire surface of the turntable 26, and a large number of muscle grooves having a serrated cross section are formed on the surface thereof.

By this series of operations, the drying or incineration area of the material to be dried is widened, and the material to be dried is burned by the air dried or incinerated at high temperature in the dry incinerator 11A and the heated upper turntable 26. Efficiently dried or incinerated.

An example of a case in which the three baffle plates 45 gradually change the gap between the upper turntable 26 and the dry burned material to the upper side surface of the upper turntable 26 is gradually expanded. As described above, the gap between the baffle plate 45B on the most upstream side and the upper turntable 26 is narrowed,
This baffle plate 45B may spread the material to be dried over the entire surface of the upper turntable 26. in this case,
It is desirable that the middle baffle plate 45C is set to a clearance approximately equal to that of the most upstream baffle plate 45B, and the most downstream baffle plate 45D is set to a narrower gap than the most upstream baffle plate 45B.

Next, the material to be dried, which is finally spread by the baffle plate 45D on the most downstream side, reaches the guide plate 46 while being efficiently dried or incinerated, and reaches the guide plate 46.
And the upper turntable 2
6 is guided to the outer peripheral edge. As a result, the material to be dried falls downward from the gap between the casing 25 and the upper turntable 26.

The dried combustion product is guided by the second chute 33 and drops onto the upper side surface of the lower turntable 27. After that, the baffle plates 48 and the guide plates 49 act in the same manner as the baffle plates 45 and the guide plate 46 on the upper turntable 26 to further dry or incinerate the material to be dried.

Then, the burned material to be dried falls on the guide plate 49 to the bottom surface of the dry incineration chamber 11A, and the lower turntable 2
It is scraped by the blade 51 rotating with the rotation of 7, and discharged from the discharge port 52 to the screw conveyor 39. In addition, a plurality of blades 51 are provided,
Similar to the case of the baffle plate 45, the gap between the blade 51 and the bottom surface of the dry incineration chamber 11A is set narrower toward the downstream blade 51. As a result, also on the bottom surface, the material to be dried is spread and dried or incinerated.

As described above, on the upper side surfaces of the upper turntable 26 and the lower turntable 27, the material to be dried is provided with a large number of streak grooves, or is uniformly spread on a flat surface to dry it. Since it can be incinerated, stable drying or incineration work can be performed without unevenness in drying or incineration.
