 Based on such groove formation, the case where waste such as a waste engine is now incinerated, and then the debris is not discharged, that is, the traveling device is moved from the state shown in FIG. 12 to the state shown in FIG. To move to the IS diagram mode, drive the forward / reverse motor 73 to pull the towing belt.

7 Turn 4 in the B direction. In this case, since the engaging lever ⁷⁶ is engaged with the engaging hole 80, the platform 67 is towed rearward while being kept in the horizontal mode. Then, when reaching the rear end, the motion transmission rod 81 is moved to the end.

It is pressed against 8 3. At the same time, the locking claw portion 84 of the locking lever 85 engages with the locking knob 87, and the traveling device is stopped steadily. When the operation transmission rod 81 is pressed, the engagement lever 76 rotates counterclockwise to engage the engagement claw 78. The hole 80 is disengaged.

 Thus, according to this traveling device, the platform 67 can be held firmly and at the same time the traveling device can be stopped and held when the traveling device reaches the rear limit. Therefore, safe and stable driving can be performed.

 Next, Fig. 14 shows the details of the case where the aluminum melted pan is placed on the roof of the aluminum melter.

In FIG, 8 8 gas generating furnace, 8 ⁹ combustion reaction column, 9 0 A Le Mi melting furnace 9 1 is shows a driving device. In such a case, a recess is formed on the rooftop 92 of the aluminum melting furnace 90, and the aluminum melting pan S3 is disposed there. In addition, a stairway 94 leading to the roof 92 is provided.

Because of this, the heat in the aluminum melting furnace 90 is transmitted to the aluminum melting pan ⁹³ through the concave roof and the thin roof. By putting aluminum roses and small pieces into the pan, they can be melted. Therefore, aluminum lumps, small pieces, etc. can be melted and shaped without requiring a separate heat source. Further, a return aspect of the present invention having a feature in the combustion reaction tube will be described with reference to FIG.

 In the figure, reference numeral 95 denotes a combustion reaction tube, and reference numeral 96 denotes a secondary air injection ffi-nozzle ejected from the gas flow flowing through the combustion reaction tube 95 while kneeling the secondary air. 7 indicates a single venturi cylinder around the nozzle 96

 In such a structure, a large number of small concave and convex surfaces 99 are formed on the inner peripheral wall 98 beyond the above-mentioned one-piece cylinder 97 of the bench lily.

 As an example of a large number of small uneven surfaces 99, when forming the combustion reaction tube 95 with a refractory material, the inner peripheral wall 98 is provided with a nadir 100 by a navel. In other words, it is possible to give an example in which the surface is made uneven.

 Alternatively, a small projection 101 may be formed and used as an uneven surface. In the example shown in the figure, an example is shown in which the projection 10 1 and the projection 10 1 are formed. However, either one of them may be used, or the low unevenness may be used.

Yo you and Do搆或based on rather of this, gas generated in the gas Mizunoto production furnace is you flow into the base down Ji Interview rie鄯of combustion reaction tube ^{9 5.}

On the other hand, since the secondary air is given a circulating flow from the nozzle 96 and flows into a part of the venturi, the air is evenly mixed with the gas. Then, the mixed gas and the fired flow which have been rotationally stirred flow through the inner peripheral wall 98 of the roasting reaction tube by centrifugal force. At this time, the inner peripheral wall surface 98 has a large surface area because the inner wall surface 98 is shaped or uneven. Ri, contact of the mixed gas you ¾f to the uneven surface 9 ⁹ of the inner peripheral wall 9 8 was red-hot is large bet Tsu name, the inner peripheral wall surface ^{9 8} whether we mixed gas, Yo rather than heat is transferred Ri good . In addition, the flow of the mixed gas is disturbed by the uneven surface 99, so that the residence time becomes longer, and the contact time between the glowing uneven surface 99 and the mixed gas becomes longer. The heat is better transmitted. As a result, the mixed gas that is not ignited immediately ignites and burns. On the other hand, a relatively light-weight gas that has been completely burned passes through the center of the combustion reaction tube. As a result, flinting of the generated gas is better enabled.

 Furthermore, another embodiment of the present invention having a feature in the combustion reaction tube will be described with reference to FIG.

1 0 ² a combustion reaction column as shown in the drawing 1 0 ³ secondary air injection Roh nozzle, 1 0 4 Baie emissions Chi Yu Li one cylinder of base down Chi Yu Li part 1 0 5 is one form And show. In such a case, a space 108 is formed between the outer peripheral surface 106 of the bench lily cylinder 104 and the inner peripheral surface 107 of the combustion reaction cylinder 102. You In this case, the space 108 is a bench lily

The root 1110 {¾} of the bench lily cylinder 10 is closed, although it is open at the tip 109 side of the cylinder.

 In this case, when secondary air is ejected from the gas jetting nozzle 103 to the gas generated in the gas kiln, the gas is mixed with each other, Although the combustion reaction occurs where the mixing has progressed, the combined combustible mixture turns around and accumulates in the above space 108, so the space 108

OMPI WIP The combustion reaction is continuing at the place. As a result, the gas generation on the gas generating side fluctuates, etc., and the concentration of the mixed gas temporarily becomes excessively rich or dilute. When the concentration returns to normal, the heat in -t f 108 becomes the ignition source and immediately shifts to normal combustion. Therefore, the combustion reaction has good sustainability.

 Industrial applicability

 As described above, the aluminum melting furnace using waste tires and the like according to the present invention as a fuel burns wastes such as waste tires and waste plastics to produce an automobile engine. It dissolves waste containing ferrous metals, such as gin, and uses it to recover valuable aluminum. O It makes better use of the benefits.
