Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ash processing apparatus for an incinerator, and more particularly to an ash processing for an incinerator that uses a self-propelled carriage to scrape out the ash generated in the incinerator to the outside. Regarding the device.

[0002]

2. Description of the Related Art Generally, a factory is provided with an incinerator for incinerating unnecessary substances generated in the factory. After the incinerator is put into this incinerator and incinerated, ash of the incinerator is generated in the incinerator. Conventionally, the ash generated in this furnace has been discharged to the outside of the incinerator by a worker using a stick or the like. Similarly, in order to make it easier to burn the incinerated material during incineration, an auxiliary combustion work has been performed in which an operator artificially stirs the ash generated in the incinerator with a stick or the like.

[0003]

If the incinerator is of a small scale or the incinerator is of a small amount, the amount of work will not be a problem even if the ash is artificially discharged to the outside of the furnace. When the incinerator is large-scale or incinerates a large amount of unnecessary substances, it is impossible to artificially discharge the ash out of the incinerator. In addition, the working environment is not so favorable, and there has been a demand to reduce human work as much as possible.
Also, the same request has been made when performing the above-mentioned auxiliary combustion work. Therefore, it is possible to treat the ash generated in the incinerator by a machine. That is, as an example thereof, it is conceivable to mount an ash processing device on a trolley that travels on a rail and discharge the ash to the outside of the furnace or perform an auxiliary combustion work. However, incinerators are often provided in relatively narrow corners in factories. For this reason, if a truck traveling on such a rail is used, a relatively large site is required to secure a required traveling range of the truck, which is not very practical considering the installation environment of the incinerator. Conventionally, when the ash is artificially discharged by a worker to the outside of the incinerator by using a rod or the like, the temperature of the ash is high immediately after the incineration of the incineration object, so that the worker is After confirming that the temperature of the ash has dropped, you have to perform the ash scraping work,
There was also a problem with work efficiency. Further, in the case of artificially carrying out the auxiliary combustion work, because of the high temperature, it was only possible to stir the vicinity of the surface of the incinerated material, and long-time work was impossible. Therefore, it was not possible to obtain a sufficient auxiliary combustion effect.

Therefore, the present invention has been made on the basis of a conventional request, can be applied to an incinerator which is often installed in a relatively small site, and efficiently occurs in the incinerator. It is an object of the present invention to provide an ash processing device for an incinerator that can perform ash processing such as scraping out ash.

[0005]

In order to achieve the above object, the present invention relates to an ash treatment apparatus for an incinerator that treats the ash produced in the incinerator, and an ash that treats the ash produced in the incinerator. A scraping rod, a cooling device that forcibly supplies cooling water to the inside of the ash scraping rod to cool the ash scraping rod, a self-propelled carriage equipped with the ash scraping rod and capable of traveling in a planar direction, And a drive device that drives the ash scraper in the vertical direction and is mounted on the self-propelled trolley. In the ash processing apparatus for an incinerator of the present invention thus configured, the ash generated in the incinerator is processed by the ash scraper. At this time, cooling water is forcibly supplied to the inside of the ash scraping rod by the cooling device, so ash treatment is performed even at a relatively high temperature during incineration or at a high temperature after a relatively short time after incinerating the incinerated material. Can be done efficiently. Further, since the driving device can drive the ash scraper in the vertical direction, the efficiency of the work itself is improved. Furthermore, since a self-propelled trolley capable of traveling in the plane direction is used, it is possible to travel even in a comparatively small site, and there are few restrictions on installation. Further, in the present invention, a nozzle portion may be formed in a portion of the ash scraper to be inserted into the incinerator, and water may be sprayed from the nozzle portion into the incinerator.

By thus configuring the present invention,
When the ash is scraped out of the furnace, it is possible to prevent re-combustion of the incineration material (dust, etc.) in the incinerator and effectively prevent the generation of smoke.

As a result, the ash scraping rod 14 that is an integral structure with the movable frame 44 is driven up and down. At this time, the drive speed in the vertical direction of the ash scraper 14 can be adjusted by the transmission 50. Next, the ash scraping rod 14 will be described in detail with reference to FIGS. 2 and 3. The ash scraping rod 14 has a double pipe structure in which the inner pipe 60 and the outer pipe 62 are formed, and the inner pipe 60 and the outer pipe 62 communicate with each other at the tip of the ash scraping rod 14. Has become. An inlet 64 is attached to the inner pipe 60, and a drain 66 is attached to the outer pipe 62. This inlet 6

The operation of the embodiment of the present invention thus constructed will be described. First, as shown in FIG. 1, the incinerator is automatically charged into the incinerator 1 from the incinerator charging port 2 by the automatic charging machine 4. Then, the incinerator 1 incinerates the incinerated matter, and a large amount of ash is accumulated in the incinerator 1. On this occasion,
Conventionally, after confirming that the temperature in the incinerator has sufficiently decreased, the worker was performing the ash scraping work, but in the example of the present invention, it was confirmed that the temperature in the incinerator had sufficiently decreased. It is not necessary to do so, and the ash scraping operation is started when the temperature in the furnace falls to a certain value, which is a high temperature to some extent. When performing the ash scraping work, the body frame 15
An operator rides on the rear end of the vehicle, and the operator operates the automatic carriage 12 as follows. That is, the trolley 12 is moved forward by switching the traveling operation knob 28 provided on the operation lever 26 to the forward position, and conversely, the trolley 12 is switched by moving the traveling operation knob 28 to the reverse position.

At this time, by switching the high / low speed changeover switch 32 between two stages of high speed and low speed, it is possible to obtain two kinds of traveling speeds of high speed traveling and low speed traveling. When starting traveling of the automatic carriage 12, the operation lever 2
6 is moved from the parking position (between points C and D shown in FIG. 2) to the traveling range (between points D and E). Further, by steering the operation lever 26 between points F and G in FIG. 3, the entire carriage drive unit 20 rotates at the portion A in FIG. 2, and only an angle equivalent to the steering angle of the operation lever 26. The drive wheels 24 are steered. Thus, a single drive wheel 24
Since the steering wheel is steered by and the steering angle is set to be very large, the turning radius of the automatic carriage 12 becomes very small, and it is possible to travel in a narrow site.

The automatic trolley 12 is operated to drive the incinerator 1
The ash inside is scraped out by the ash scraping rod 14, and at this time, the ash scraping rod 14 operates as follows. That is, the ash stick 14
In order to scrape out the ash in the incinerator 1, the operator must move the ash scraper rod 14 in the furnace in the longitudinal direction, the width direction, and the vertical direction. The movement in the longitudinal direction is performed by switching the traveling operation knob 28 to forward or reverse,
The movement in the width direction is performed by steering the operation lever 26 by a desired amount, and the movement in the vertical direction is performed by the operation lever 26.
This is done by operating the elevating switch 32 of. Also,
At this time, the cooling water is forcibly injected into the inner pipe 60 into the injection port 64 of the ash scraping rod 14, and the injected cooling water flows into the outer pipe 62 through the inner pipe 60 and the communication part at the tip. Then
Since the ash scraping rod 14 is discharged to the outside through the drainage port 66, the ash scraping work can be performed at a relatively high temperature. As described above, in this embodiment, the work of scraping out the ash generated after the incineration of the incinerator 1 to the outside of the furnace can be performed.
In order to make it easier to burn the incinerated matter during incineration, it is also possible to insert the ash scraper 14 into the incinerator 1 during incineration to perform an auxiliary combustion work of stirring the incinerated matter. In this case, the operator operates the ash scraping rod 14 in the longitudinal direction, the width direction, and the vertical direction in the furnace, as in the above-described ash scraping operation. As a result, the ash scraping bar 14 stirs not only the surface of the incinerated material but also the inside and the lower part of the incinerated material, so that the combustion supporting effect is increased.

Next, another embodiment of the present invention will be described with reference to FIG. FIG. 4 is a partial side view showing another embodiment of the incinerator ash processing apparatus of the present invention. In this embodiment, a sprinkling pipe 70 made of a heat resistant material is provided along the ash scraper 14. This sprinkling pipe 7
One end of 0 is connected to the above-described drainage port 66, and a part of the cooling water of the ash scraping bar 14 branches from the drainage port 66 into the sprinkling pipe 70 and flows out. The sprinkler pipe 70 is fixed to the truck 12 near the branch portion, and an opening / closing valve 72 is provided at that portion. The other end of the water sprinkling pipe 70 extends to the tip of the ash scraper 14, and a water sprinkling nozzle 74 is formed at the tip. In the other embodiments, the basic operation is the same as that of the above embodiments. In another embodiment, when the ash scraping work is performed, a part of the cooling water of the ash scraping bar 14 is used during the ash scraping work to spray the water with the spray nozzle 74 of the spray pipe 70.
Therefore, water is sprinkled into the incinerator 1. As a result, it is possible to prevent re-combustion of incineration materials (dust, etc.) in the incinerator 1 and effectively prevent smoke from being generated.
