Description

  The present invention relates to a conveyor device, and more particularly to a conveyor device used to transport a wet kneaded material obtained by kneading incinerated fly ash generated in a garbage incinerator, water, and a chemical as a transported material.

In a garbage incinerator, in order to confine heavy metals contained in incineration fly ash, the incineration fly ash, water and chemicals (chelating agent and cement) are mixed into a wet kneaded product, which is then cured and solidified on a conveyor device. It is made to discharge while letting.
Conventionally, a flat belt conveyor has been generally used as a conveyor device used to convey such a wet kneaded product (see Patent Document 1).

  Usually, a predetermined time (30 to 60 minutes) is required for curing and solidifying the wet kneaded product. Therefore, when a flat belt conveyor is used as the conveying means, it is necessary to lengthen the flat belt conveyor.

  By the way, when disposing of incinerated fly ash in an existing facility, due to site restrictions, it is difficult to place a conveyor with sufficient installation space, and the wet kneaded material is cured and solidified using a conveyor device with a gradient. However, it becomes a situation that must be transported.

In addition, the wet kneaded material is likely to adhere to the belt of the belt conveyor due to the moisture, and this may solidify and harden and gradually accumulate.
Even when the wet kneaded material adheres to the belt of the belt conveyor and is solidified and cured, the kneaded material adhering to the surface is naturally peeled off by the curved transition when the belt is reversed at the end. There is an advantage that the kneaded material that falls and adheres can be automatically removed.

However, as described above, the conveyor device must be installed with a gradient due to the installation space, and the wet kneaded material placed on the belt may slide down due to the gradient.
In order to prevent this, it is necessary to provide on the belt a backing plate for supporting the wet kneaded material from below, and there is a problem that the conventional flat belt conveyor cannot be used as it is.
Japanese Patent Publication No. 2003-334511

  The present invention prevents the wet kneaded material from being slid down even when the conveyor device is installed with a gradient in order to facilitate securing the installation space. Can be transported while reliably curing and curing on an upward slope, and even when wet kneaded material adheres and solidifies and hardens, this kneaded material can be automatically peeled off as the conveyor operates. It is an object to provide a conveyor device.

In order to solve the above problems, the conveyor device of the present invention is
Left and right rotating chains (13), (13) suspended between the sprockets (11), (12) and receivers installed at regular intervals between the left and right rotating chains (13), (13) A plate (21) and a bendable belt member (22) passed between the receiving plates (21), (21);
The endless belt-like body (2) in which the backing plate (21) and the belt member (22) are alternately arranged is attached between the left and right rotating chains (13) and (13).

  In addition, the code | symbol in the said parenthesis shows a corresponding relationship with the specific means described in the Example mentioned later.

  In the conveyor device of the present invention, an endless belt-like body is attached between the left and right rotating chains, and the endless belt-like body is installed between the left and right rotating chains at regular intervals and between the receiving plates. The passed bendable belt members are formed alternately.

  Therefore, in the conveyor apparatus of the present invention, since it is a drive system that moves the endless belt-like body by the left and right rotating chains, the belt does not slip as in the belt conveyor, and the object to be conveyed (wet kneaded material) Can be reliably transported in a state of being placed on the endless belt.

  In addition, since the endless belt-like body is formed by alternately arranging the receiving plate and the belt member, the object to be conveyed can be supported from the lower side by the receiving plate even if it is an upward gradient, and the object to be conveyed is Receiving sliding down, it can be reliably conveyed.

Also, when the transported object is a wet kneaded product, the endless belt-like body reverses the sprocket at the end as the rotating chain is driven even if the wet kneaded product adheres to the belt member and solidifies and hardens. The wet kneaded material is naturally peeled off from the surface of the belt member due to the curved transition at the time.
This can automatically prevent the wet kneaded material from adhering to the surface of the belt member and solidifying and hardening.

  That is, the conveyor device of the present invention takes advantage of the advantage of the belt conveyor that the kneaded material adhering to the belt surface can be naturally peeled off by the curved transition when reversing, and the adhering solidified and cured kneaded material can be automatically removed. In order to facilitate the securing of the installation space, even when the conveyor device is installed with a gradient, the wet kneaded material as the transported object is prevented from sliding down, and the wet kneading is prevented. Objects can be transported while being solidified reliably on an ascending slope.

  FIG. 1 is a side sectional view showing a conveyor device of the present invention, and FIG. 2 is a partial plan view of the conveyor device.

  The conveyor apparatus A of the present embodiment is for discharging incineration fly ash from a garbage incinerator, and a wet kneaded material in which water and chemicals (chelating agent or cement) are mixed with the incineration fly ash is a transported object. It is incorporated in the casing 9.

  The casing 9 has a wet kneaded product inlet 91 formed on the upper surface of the lower end, a wet kneaded product discharge port 92 formed on the lower surface of the lower end, and a wet kneaded product discharge port 93 formed on the lower surface of the upper end. It is formed in the shape of a formed tunnel, and is inclined at a certain angle so as to rise upward from the lower end toward the upper end.

In the conveyor device A, left and right rotating chains 13, 13 are suspended between a driving sprocket 11 provided at the upper end and a driven sprocket 12 provided at the lower end, and an endless belt-like shape is formed between the left and right rotating chains 13, 13. The body 2 is attached.
The endless belt 2 includes a receiving plate 21 laid between the left and right rotating chains 13 and 13 at regular intervals, and a bendable rubber belt member 22 passed between the receiving plates 21 and 21. They are formed alternately.
In addition, although the cross-sectional T-shaped mold material is used as the receiving plate 21, an L-shaped cross-sectional material may be used. In short, the receiving plate 21 is formed on the endless belt-like body 2 provided in an upward slope. Any wet kneaded material (conveyed material) may be supported from the lower side so that the wet kneaded material can catch the sliding down due to the gradient.

  In this case, brackets 14, 14 project inwardly on every other link plate on the left and right rotating chains 13, 13, and adjacent belt members 22, 14 are provided on the brackets 14, 14. In addition to mounting the end portions of the belt member 22, the receiving plate 21 is overlapped so as to straddle the end portions of the belt members 22, 22, and is fixed by bolts, nuts, or the like.

  In this embodiment, rubber scrapers 23 are attached to the receiving plate 21 every several pieces (the scrapers 23 may be attached to all the receiving plates 21), and the scraper 23 is attached to the bottom of the casing 9. The wet kneaded material that has been moved while contacting the wall surface 94 and dropped onto the bottom wall surface 94 is scraped downward and discharged from the scraping port 92.

In such a conveyor device A, when a drive motor (not shown) is driven, the left and right rotating chains 13 and 13 are moved between the sprockets 11 and 12 in the casing 9 along with the endless belt 2 by the rotation of the drive sprocket 11. To recirculate.
Therefore, when the wet kneaded material is charged from the charging port 91 of the casing 9, the wet kneaded material is placed on the endless strip 2 having an upward slope and conveyed toward the discharge port 93.
At this time, since the receiving plate 21 is provided, the wet kneaded product can be supported from the lower side even in the upward slope, and the wet kneaded product can be reliably conveyed.

Further, even when the wet kneaded material as the object to be conveyed adheres to the belt member 22 and is solidified and cured, the endless belt-like body 2 is curved when the driving sprocket 11 portion at the upper end and the driven sprocket 12 portion at the lower end are reversed. The wet kneaded material is naturally peeled off from the surface of the belt member 22 with the transition.
Thereby, it is possible to automatically prevent the wet kneaded material from adhering to the surface of the belt member 22 and solidifying.

  In addition, after the endless belt-like body 2 with the upward gradient reversely shifts the drive sprocket 11 at the upper end, the wet kneaded material may fall on the bottom wall surface 94 of the casing 9 from the endless belt-like body 2 with the downward slope. The wet kneaded material is scraped downward by the scraper 23 attached to the receiving plate 21 and discharged from the scraping port 92.

In the present embodiment, the wet kneaded material is a material to be conveyed, but the present invention is not limited to this, and can be suitably used for powders and granules, earth and sand, mud, and the like that are easily attached.
Moreover, although the conveyor apparatus was formed in the mere upward slope, an appropriate circulation path can be formed, for example, a horizontal transition part is formed in a lower end part and an upper end part.

It is side surface sectional drawing which shows the conveyor apparatus of this invention. It is a partial top view of the conveyor apparatus.
