Description

[Detailed description of the invention] The present invention relates to an apparatus for recycling waste asphalt.

Conventional drum-type regeneration and heating equipment for producing asphalt recycled materials does not have any means of keeping the rotating drum warm.
In addition, since the recycled material JiF outlet was always left open, not only was a large amount of thermal energy was wasted, but incompletely melted material was discharged at the start of recycling, resulting in a decrease in the quality of the recycled material. .

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, it is an object of the present invention to provide an asphalt waste recycling apparatus in which a rotating drum is covered with a heat-insulating cover and a recycling material discharge port is provided with an opening/closing hatch.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is a rotating drum that has a raw material supply port 2 on one side for inputting asphalt waste material, and a recycled material discharge port 3 on the other side for discharging recycled material produced by heating and melting the waste material. . The rotary drum 1 is rotatably supported on a transport vehicle 4 by rollers (not shown), and is supported so that its axis is tilted downward so that the recycled material discharge port 3 side is located slightly downward. The inside of the rotary drum 1 is divided into two parts in the axial direction via a screen 5, and a cylindrical first chamber 6 has a large number of blades 7 on the inner circumferential wall of the rotary drum 1 to agitate the raw material by the rotation of the rotary drum 1. A protruding tower,
Further, a plurality of blades 9 are protruded from the inner peripheral wall of the truncated conical second chamber 8 which communicates with the first chamber 6 via the screen 5 to transfer the recycled material to the discharge port 3 side. .

The rotating drum 1 is rotated by a drive motor 10 with a speed reducer installed on a transport vehicle 4 via a chain 11 or the like. In addition, a discharge port 13 of a bomber 12 faces the upper half of the road of the raw material supply port 2 of the rotary drum 1, while a pump for heating the raw material stored in the first chamber 6 is located approximately in the lower half of the rotary drum 1. The outlet (5) of the burner device 14 is facing.

The burner device 14 is of a gun type that generates a long flame section, and a flame reflector plate 16 is provided at the center of the scree 15 opposite to it. The burner device 14 also includes a 17th ann 19 that supplies a sufficient amount of air to burn the petroleum fuel supplied to the nozzle 18 through the fuel pipe 17, and a long first air outlet that is generated from the air outlet 15.
A second fan 22 is attached to the casing 23 to form a second flame part 21 in a disturbed state outside the flame part 20 and thereby supply a sufficient amount of air to burn the asphalt combustible gas near the raw material supply port 2. Of course, this burner device 14 is mounted on the transport vehicle 4 by means of suitable support members (not shown). l The upper half of the road of the rotating drum 1 configured in this manner is covered by a heat insulating cover 24. Note that the heat retaining cover 24 can also be attached so as to cover the entire rotating drum 1. An opening/closing hatch 25 is provided at the recycled material discharge port 3 of the rotating drum 1. The opening/closing hatch 25 is connected to a vertical plate 26 vertically disposed opposite to the heat insulation cover 24 and the recycled material outlet 3.
Screw the threaded shaft 28 of the handle 27, and
The bearing housing 3 is attached to the tip shaft portion of the bearing housing 3 through the bearing 29.
0, and this bearing housing 30 is attached to the spring 31.
It is supported by being attached to the center of the hatch 25 with a bolt 32 interposed therebetween.

In addition, 33 is a sieve m 33 connected to the recycled material discharge port 3.
The recycled asphalt material can be sieved when it is discharged. The asphalt waste auxiliary hopper 35 provided at the front of the transport vehicle 4 is a belt-type or flight-type conveyor for conveying the asphalt waste loaded into the auxiliary hopper 34 to the hopper 12.

Next, the operation of the apparatus of the present invention configured as described above will be explained.

Asphalt waste is transferred from the auxiliary hopper 34 to the conveyor 36
The raw material is put into the hopper 12 and supplied in a predetermined amount to the first chamber 6 of the rotating drum 1 through the raw material supply port 2. The opening/closing hatch 25 is closed while the Asquard waste material is completely recycled and manufactured. Then, as the rotary drum 1 is rotated, the burner device 14 heats and melts the asphalt waste material inside the drum.

The asphalt waste material in the first chamber 6 is stirred by the blades 7 and heated by the burner device 14 . Moreover, the recycled material discharge port 3 of the rotating drum 1 has a hatch 25 for opening and closing.
Since the rotary drum 1 is further covered by the heat insulating cover 24, the burner device 1
4, the asphalt waste is sufficiently heated and melted in the first chamber 6.

The recycled asphalt material heated and melted in this way is fed into the second chamber 8 through the screen 5, and then the opening/closing hatch 25 is opened and the blade 9 is used to discharge the recycled material into the recycled material outlet 3.
is discharged to the outside.

The reclaimed asphalt material obtained in this way is sufficiently heated within the rotating drum 1, so that it is of extremely high quality. In addition, during recycling, at least the recycled material discharge port 3 is closed by the opening/closing lever 25, and the rotating drum 1 is kept warm by the heat insulating cover 24, so there is less wastage of thermal energy and thermal efficiency is improved. It is excellent in this respect.

As described above, according to the present invention, it is possible to obtain high-quality recycled asphalt material, and there is little wastage of thermal energy.
