When the drive motor 131 operates according to the signal of the control unit shown in FIGS. 1 and 2 at the same time as the start of the operation, the connected drive shaft 133 rotates, and the driven gear 135 and the meshed drive shaft rotate in a direction facing each other. Rotate the cutter. At this time, the cutter is arranged such that a blade (not shown) has a screw shape along the axial direction of the drive shaft.

At the same time, when the incinerated material is put through the hopper 122, it is crushed to a predetermined size by the rotating cutter and falls to the lower part, and the fallen incinerated material is input by the transfer device 20 shown in FIGS. 1 and 4 . It falls to the hopper 211 and falls on the transfer unit 220 side in the body 210 , and moves while being wrapped around a certain amount on the transfer plate 224 side in the transfer unit 220 .

The incinerated material conveyed in a state wrapped in the conveying plate reaches the discharge hopper 212 and freely falls to the discharge hopper side by the return of the conveying part, and falls and is put into the incinerator side.

At this time, air is sprayed from the discharge hopper side to the incinerator side from the injection unit 240 disposed on the discharge hopper 212 side, so that the falling incinerated material can be naturally put into the incinerator side, so that it is lost to the outside of the incinerator during the input process. Not only can it be prevented, but it can also perform the function of an air curtain to prevent the flame of the incinerator from flowing back through the discharge hopper.

The incinerated material injected into the combustion space 321 inside the incinerator 30 is heated and burned through the fuel supplied through the combustion line 330 , and is completely burned by the combustion air supplied by the blower pen 341 . .

In addition, auxiliary fuel is supplied through the auxiliary combustion housing 430 as needed in the combustion process. The auxiliary combustion housing is located above the combustion housing 410 to promote combustion of the combustion housing through the auxiliary combustion housing. do. The operation of the auxiliary combustion housing is operated through the temperature sensor attached to the incineration body.

In addition, the supplied air is injected at regular intervals in the height direction by a plurality of injection nozzles 511 formed in the air injection unit, and the injection direction is alternately injected in a clockwise or counterclockwise direction as shown in FIG. 16 . will do

Here, it is preferable that the spacing between the injection nozzles gradually becomes narrower in the height direction, and the diameter of the injection nozzles gradually increases in the height direction.

This prevents the flame of the combustion process from rising to the top and discharged to the outside by increasing the amount of air injected from the upper injection nozzle than the amount of air injected from the lower injection nozzle, and forming an air curtain on the upper side to form an incinerated product that is incompletely burned. to incinerate once more.

The arrangement and structural form of the injection nozzle are as shown in FIGS. 17 and 18 .

In the process of being incinerated through the incinerator, the stirring device 60 shown in FIG. 19 is operated to agitate the incinerated material in the incinerator to further increase the incineration efficiency.

To this end, the stirring device operates the operation rod 740 through the driving means 720, and at the same time sprays air directly to the incineration through the operation rod 740 and controls the operation of the operation rod through a sensor to advance the operation rod, It is possible to completely burn the incinerated material by repeatedly performing retreating and efficient agitation.

Fine dust that may be generated during incineration of incinerated material can be collected and processed through water sprayed through the injection nozzle installed on the exhaust device 70 side, and the collection of fine dust through a separate chemical treatment in the sprayed water It is possible to promote

In this way, when the present invention is used, it is possible to completely burn the incinerated material, and the entire structure can be installed in a small incinerator, so that not only can the cost for installing the incinerator be significantly reduced, but also the odor generated during incineration, fine dust, etc. It is possible to install an environmentally friendly incinerator because it can minimize the occurrence of

As mentioned above, although the present invention has been described through preferred embodiments, this is only intended to help the understanding of the technical content of the present invention, and is not intended to limit the technical scope of the present invention.

That is, without departing from the technical gist of the present invention, various modifications and alterations are possible by those skilled in the art to which the present invention pertains, and such alterations or alterations are within the technical scope of the present invention in the interpretation of the claims. It goes without saying that it is within.
