Description

[Detailed Description of the Invention] This invention relates to a machine that dissolves and regenerates concrete asphalt waste, which is industrial waste. Conventionally, most of the concrete asphalt waste was discarded as industrial waste. Some methods include dismantling the wood with hot water or steam and separating it into asphalt and aggregate for reuse, but this method is only used by a limited number of organizations because of the high equipment and maintenance costs. The concrete asphalt waste material melting and recycling machine we invented this time uses conventional steam. This is different from a machine that uses hot water to disintegrate wood. Concrete asphalt mix (hereinafter referred to as recycled asphalt mix) is put into the rotating drum while the drum is rotating. Direct flame is blown into the drum, and the recycled asphalt mixture is heated and melted while avoiding the direct flame. This is to perform mixing and take out. This will be explained using drawings. Figure 1 is a side view of a plant in which the concrete asphalt waste recycling machine of the present invention and associated equipment are connected. Store recycled asphalt mixture in hopper 1. The stored recycled asphalt mixture passes through a feeder 2 and is transferred to a supply conveyor 3.

The drive motor 6 rotates the rotating drum 7 and the burner blower 5 is ignited. The burner fire heats the inside of the rotating drum.

The recycled asphalt mixture on the feed conveyor is fed into the superheated rotating drum 7 via the input shoe 4 and then transferred to the rotating drum 7.
is supplied into the . The recycled asphalt mixture produced by superheated melting and mixing in the rotating drum 7 is fed into the measuring device 10. When the amount reaches a certain level, open the door and take bucket 1.
Send it into 2. The recycled asphalt mixture in the bucket 12 is. Ship directly to truck 14 via skip hoist 13 or. Send it to the hot silo and store it. If necessary, the products are shipped from the lower part of the hot silo 15.

8 is a rotating drum 7. Burner blower 5 Drive motor 6.
This is the pedestal on which the input chute 4, etc. is placed. 9 is an exhaust tower that mainly releases water vapor contained in the recycled asphalt mixture. Reference numeral 11 denotes a discharge conveyor, on which recycled asphalt mixture that does not meet the standards is discharged and used for roadbed materials, etc.

This shows the shape of the blade of the metal piece 22 that acts in the direction of returning the flow. In FIG. 3, when the recycled asphalt mixture flows into the vane-shaped part of the blind area in FIG. 2, the rotating drum 7
This diagram shows the state inside. Figures 2, 3, and 4 will be explained. The rotating drum 7 is rotated by the drive motor in the direction shown by the arrow in the figure. Next, the burner blower 5 is ignited to heat the inside of the rotating drum 7. When the rotating drum 7 reaches a certain temperature, recycled asphalt mixture 23 is released from the input chute 4.
into the inlet of the rotating drum 7. The incoming recycled asphalt mixture is pushed into the drum by the spiral blades 16 without being scraped up. This is because the concrete asphalt waste material melting and regenerating machine of the present invention uses an open flame inside the rotating drum to improve the heat absorption of the burner blower. The recycled asphalt mixture 23 fed by the spiral blades is pushed into the combustion chamber 26 while rotating without being scraped up, thereby moving on its own to the left of the lower surface of the rotating drum 7 (FIG. 4B). The recycled asphalt mixture 23 that traveled on its own and reached part C. At this point, it is undissolved or in the form of powder, so the reverse L
Four scraping pieces 17 each having a claw at the tip thereof are attached. The reason why there are four scraping pieces 17 in part C is that
The density of the screen-like film in the section D is thinner than that in the D section. If the density of the membrane is low, the heat from the burner blower will reach the D section, allowing it to be heated evenly. Furthermore, if the first screen in the C section is made dense, hot air will bounce back and the hot air will come out from the input chute 4, so the screen density in the C section is made thinner. Further, in order to make the screen-like film inside the rotating drum 7 uniform, the scraping pieces 17, 17, 19, 20 are attached at different angles so that they are not aligned horizontally. In Figure 4 E and F. Because the recycled asphalt mixture 23 becomes viscous, the inverted L-shaped pawls are not installed. Figure 4C
, D, the recycled asphalt mixture 23 tends to fall upward when the rotating drum rotates. E diagram is F
Compared to the figure, the density of the screen shape (in this place, it becomes a bar-like screen) is thinner. The heat received by the recycled asphalt mixture 23 in the EF is made uniform. In Figure 4G. The principle is explained in Figure 6 using a metal piece installed to stir the recycled asphalt mixture that comes out of the melt. The arrow indicates the direction in which the rotating drum rotates, and the dotted arrow indicates the direction in which the recycled asphalt mixture flows. The metal pieces 21 act to accelerate the flow of recycled asphalt mixture as the drum rotates. The recycled asphalt mixture sent from 21. By 22. It is pushed back as if pushing back against the flow.

The size of the metal piece being returned is smaller than the size of the metal piece being accelerated. Also, by reducing the number. Stirring is performed as if moving forward 2 times and returning 1 time.

The concrete asphalt waste material melting and recycling machine of the present invention is
Direct flame is sent into the rotating drum using a burner blower. As shown in Figure 5B1. Since the flame has the shape of a random open flame 24, it is used as recycled asphalt mixture 23. sometimes random fire 24
It hits and burns. Therefore, the rotation direction of the rotating drum 7 and the spiral feeding blade 16 are aligned. As the rotating drum rotates, wind is generated and blows inside the drum in the same direction as the flow of recycled asphalt mixture. This wind turns the turbulent open flame 24 into a well-organized flame, ie, an ordered open flame 25, as shown in FIG. 5B2, and prevents the recycled asphalt mixture 23 from being hit by the open flame.
