Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration type kneading and granulating apparatus for kneading fly ash containing metal while kneading it with a predetermined medium for processing.

[0002]

2. Description of the Related Art Generally, incinerated fly ash of municipal solid waste contains a metal, and therefore fly ash containing the metal (hereinafter referred to as a raw material) needs to be detoxified by a method specified by the Ministry of Health and Welfare. .

As a device for detoxifying and treating such a raw material, there is a vibration type kneading and granulating device, and this vibration type kneading and granulating device is vibratably supported on a base through a suspension. A vibrating kneading drum and a vibration motor for vibrating the vibrating kneading drum are provided. By feeding the raw material from the charging port provided in the vibrating kneading drum, the vibrating kneading drum vibrates the vibrating kneading drum. , The granulation raw material is kneaded with cement, water, pH adjuster, and metal stabilizer (also called chelating agent) to form granules, which are discharged from the discharge port to a predetermined place through the discharge guide plate attached to the vibration kneading drum. Is configured.

[0004]

In the vibration type kneading and granulating apparatus as described above, since the discharge guide plate does not have the length necessary for curing the raw material, the granular raw material has a rough surface portion. Also, it is discharged from the discharge port in a sharp state. Such a granular raw material has a weak strength, and therefore, there are problems that the granular raw material is broken during transportation, and the pointed portion is particularly likely to be chipped during transportation.

Therefore, an object of the present invention is to provide a vibration type kneading and granulating apparatus which can solve the above problems.

[0006]

Means for solving the problems in the present invention is a vibrating kneading and granulating apparatus for kneading fly ash containing metal while kneading with a predetermined medium while vibrating. A vibration kneading drum is attached to the base via a vibration spring, a vibration means for vibrating the vibration kneading drum is provided, and a fly ash charging port is arranged on one side of the vibration kneading drum. A discharge port for discharging the kneaded particulate fly ash mixed with the medium is arranged on the other side, and a guide plate for guiding the kneaded granular fly ash to the discharge port side is provided. A baffle plate for temporarily retaining the particulate fly ash guided by the guide plate on the guide plate is provided near the guide plate.

[0007]

In the above means for solving the problems, fly ash is charged from the charging port, and the vibrating means is driven to vibrate the vibration kneading drum, whereby the fly ash in the vibration kneading drum is kneaded with the medium and kneaded with the medium. The fly ash becomes particles with a rough and sharp surface and is guided to the outlet side by the guide plate.
Since a baffle is erected near the discharge port of the guide plate, the particulate fly ash is temporarily blocked from being discharged from the discharge port, and the sharp kneading part is generated by the vibration kneading drum vibrating. Is smoothed and hardened, and then discharged from the discharge port.

[0008]

EXAMPLES Examples of the vibration type kneading and granulating apparatus of the present invention will be described below with reference to the overall front view of FIG. 1 and the overall side view of FIG.

The vibration-type kneading and granulating apparatus according to the embodiment of the present invention vibrates a metal-containing raw material 1 such as municipal waste while vibrating a predetermined medium B (for example, cement, water, PH stabilizer, metal stabilizer). It is for kneading and processing.

In this vibrating kneading and granulating apparatus, a vibrating kneading drum 4 for kneading a raw material 1 with a medium B on a base 2 via a plurality of vibrating springs (also called suspensions) 3.
And a vibration motor 5 (an example of a vibrating means) for vibrating the vibration kneading drum 4 is mounted on both side surfaces of the vibration kneading drum 4 via a mounting member 6, and the vibration motors 5 are Output shaft 7 of each vibration motor 5
The transmission belt 9 is wound around a pulley 8 attached to the motor so as to be synchronously operated.

On the upper surface of the vibration kneading drum 4, the raw material 1
A charging hopper 10A having a charging port 10 for charging the vibrating kneading drum 4 is attached, and the granular raw material 1 after kneading is dropped to the outside of the vibrating kneading drum 4 at the lower part of the side surface of the vibrating kneading drum 4. 11 is formed, the base end of the discharge chute 12 is attached to the drop port 11, and a semicircular discharge port 13 is formed at the tip of the discharge chute 12 to incline the discharge chute 12. The bottom wall serves as a guide plate 14 for guiding the raw material 1 to the discharge port 13 side, and the granular raw material 1 guided by the guide plate 14 is guided to the discharge port 13 side end of the guide plate 14 on the guide plate 14. A crescent-shaped baffle 15 for standing up temporarily is erected.

A plurality of medium injection ports 16 for introducing the medium B into the vibration kneading drum 4 are arranged on the upper surface of the vibration kneading drum 4. In the above structure, the raw material 1 is charged through the charging port 10 and the medium B is injected through the charging port 16 to drive the vibration motor 5. Then, the vibration kneading drum 4 vibrates, and the raw material 1 in the vibration kneading drum 4 is kneaded with the medium B. If this state is continued for a while, the raw material 1 kneaded with the medium B becomes grains having a rough and sharp surface and drops from the drop port 11 to the discharge chute 12.

The granular raw material 1 dropped on the discharge chute 12 is guided to the discharge port 13 side by the guide plate 14, and the baffle plate 1 is provided at the end of the guide plate 14 on the discharge port 13 side.
5, the granular raw material 1 is discharged from the outlet 13
Is temporarily blocked from being discharged from the discharge chute 12, and is sequentially accumulated in the discharge chute 12. Further, by vibrating in the discharge chute 12 by driving the vibration motor 5, the sharpened portion is smoothed and becomes a nearly spherical shape. When the granular raw material 1 staying in the discharge chute 12 exceeds a predetermined amount, the granular raw material 1 is discharged from the discharge port 13 by passing through the baffle plate 15 by the vibration of the discharge chute 12.

As described above, according to the embodiment of the present invention, the granular raw material 1 is temporarily retained at the end of the guide plate 14 for guiding the granular raw material 1 toward the discharge outlet 13 side. Since the baffle plate 15 is provided, the baffle plate 15 vibrates together with the discharge chute 12 while temporarily staying on the guide plate 14, and the surface is smoothed and solidified into a shape close to a sphere, and the discharge port 13 is formed. Therefore, it is possible to improve the strength of the raw material 1 and prevent the raw material 1 from being broken during transportation.

[0015]

As is apparent from the above description, the present invention is
By providing a baffle for temporarily retaining the granular raw material near the discharge port of the guide plate that guides the granular raw material to the discharge side of the vibration kneading drum, the granular raw material can be placed on the guide plate. The granular material is vibrated together with the vibrating kneading drum in a stagnant state, the surface of the granular raw material is smoothed and solidified and discharged from the outlet, so that the strength of the granular raw material can be improved and therefore the raw material is transported. Even in the case, it can be prevented from breaking.
