Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary treatment apparatus for drying and incinerating materials having a high water content such as sludge.

Such a conventional rotary processing apparatus is shown in FIGS. 1-3.

In the first part, a conventional rotary processing apparatus is a cylinder body having a workpiece 2 connected to a screw conveyor 5 or the like at one end, a workpiece outlet 3 and a burner 4 as a heat source at the other end. 1, and the cylindrical body 1 has a population of objects to be treated 2.
It is installed with a slight downward inclination toward the outlet 3 of the processed material, and is rotated by a drive device such as an electric motor (not shown).

As shown in FIG. 2, inside the cylinder 1, a large number of raking blade groups 6a to 6a are fixed along the circumferential surface of the inner wall.
6c are arranged in a plurality of rows from the object population 2 to the object outlet 3.

When a workpiece is put into the conventional rotary processing apparatus configured as described above, the workpiece repeats a movement in which it is scraped up by the scraping blades 6a to 6c and then falls, and the workpiece is moved from the workpiece population 2 to the workpiece population 2. It is transported to three exit directions while being dried.

However, when handling materials with a high moisture content such as sludge, as shown in Figure 3, due to the high moisture content, the raking blades and the wall surface of the cylinder body near the population 2 of the material to be treated are Objects will stick to it and will not fall even when the cylinder 1 rotates.

For this reason, the object to be processed cannot sufficiently come into contact with the hot air from the burner 4, resulting in a drawback that drying and incineration of the object is insufficient.

Furthermore, if the material to be treated adheres to the raking blades, the raking blades will no longer be maintained at a high temperature, resulting in the disadvantage that the material to be processed will be insufficiently dried.

In order to solve the above-mentioned drawbacks, the present invention prevents the objects to be processed from adhering to the scraping blades, thereby fully using the heat source of the burner for drying and incinerating the objects to be processed, thereby improving the efficiency of drying and incineration. The object of the present invention is to provide a rotational processing device.

For this reason, in the rotary processing apparatus according to the present invention, a large number of raking blades are rotatably supported along the inner circumferential surface of the cylinder, and the surface of the preceding raking blade is rotated by the rotation of the cylinder. It is characterized in that the subsequent raking blades raise the raking.

Hereinafter, the rotation processing apparatus according to the present invention will be explained based on the embodiments shown in FIGS. 4 to 6.

In FIG. 4, the rotary processing apparatus is a cylindrical body having a workpiece 2 connected to a screw conveyor 5 etc. at one end, and a workpiece outlet 3 and a burner 4 serving as a heat source at the other end. 1, the cylinder 1 is installed with a slight downward inclination from the outlet 2 for the object to be processed toward the outlet 3 for the object to be processed, and is rotated by a drive device (not shown).

In the vicinity of the object to be treated 2 of the cylinder 1, a large number of raking blades 7a to 7a are rotatably supported along the circumferential surface of the inner wall.
7c are arranged in a plurality of rows, followed by a plurality of rows of raking blade groups 8a to 8e fixed along the circumferential surface of the inner wall.

The raking blade groups 7a to 7c rotatably supported are the fifth
~ It is configured as shown in Figure 6.

That is, each raking blade is supported via a rotating shaft 9 by a mounting bracket 8 fixed to the inner wall surface of the cylindrical body 1, and when the cylindrical body 1 rotates, the adjacent raking blades are fully in contact with each other up to the end of the blade. are arranged as follows.

It is preferable that the positions of the raking blades on the circumferential surface of the inner wall of the cylindrical body 1 are determined such that there is a phase difference for each row.

When a workpiece is put into the rotary processing apparatus configured as described above, the workpiece repeats a movement of being scraped up by the raking blades and then falling, from the workpiece population 2 to the workpiece outlet 3.
The material is then transported to the destination while being dried.

The rotatably supported scraping blade group moves in relation to each other so that when the cylindrical body 1 rotates in the direction of arrow A as shown in FIG. 6, the trailing blade scrapes up the surface of the preceding blade.

Therefore, the object to be treated adhering to the scraping blade 7c is scraped off during the rotation, and as a result, the object to be treated can sufficiently come into contact with the hot air from the burner 4, and at the same time, the blade itself is maintained at a high temperature, improving drying efficiency. bring about.

The number of rows of the rotatably supported scraping blade groups 7a to 7c is determined by the water content of the object to be treated, etc., and the number of rows is sufficient to ensure that the object to be treated is dry and does not adhere to the blades.

In the process of passing through the arrangement of the rotatably supported raking blade groups 7a to 7c, the material to be processed is dried and no longer adheres to the blades, so the rotatably supported raking blade group 7c
Thereafter, conventional fixed raking blade groups 8a to 8e may be arranged.

In the area where the fixed raking blade groups 8a to 8e are arranged, the object to be processed is further dried by the hot air from the burner 4.
If necessary, incineration will also be possible.

The dried material or incinerated ash transferred to the other end of the cylinder 1 is discharged to the outside from the material outlet 3.

As is clear from the above description, in the rotary processing apparatus according to the present invention, a large number of scraping blades are rotatably supported along the circumferential surface of the inner wall of the cylinder, and the rotation of the cylinder allows the preceding scraping. Since the surface of the lifting blade is configured to be scraped up by the subsequent scraping blade, not only does the material to be processed not adhere to the lifting blade, but also a space is always created between the lifting blade and the inner wall of the cylindrical body. As a result, the hot air from the burner 4 comes into sufficient contact with the object to be processed, and the raking blades are also maintained at a high temperature at all times, thereby improving the drying efficiency of the object to be processed.
