Description

Regeneration Device Of Waste Ascon

The present invention relates to a waste ascon recycling apparatus.

As is generally known, a waste ascon recycling apparatus has been developed as a means for recycling waste ascon (waste asphalt concrete). The conventional waste ascon recycling apparatus is rotatably installed by a frame and actuator power. It is largely comprised of the cylindrical rotating drum which accommodates waste ascon, and the heating means for heating the waste ascon accommodated in the said rotating drum.

Therefore, when the waste ascon is recycled, the asphalt is recycled by heating the waste ascon for a predetermined time by heating means after putting the waste ascon of the appropriate size into the rotating drum and rotating the rotating drum.

However, the conventional asbestos waste recycling apparatus having one rotating drum has an inadequate problem when repairing a large road because the amount of ascon which can be recycled at a time is limited.

In other words, when repairing large roads, waste ascon regeneration works must be repeatedly performed several times, and thus there is a problem in that regeneration takes longer and construction continuity is poor.

On the other hand, although the rotating drum is divided into a plurality, the waste ascon regeneration device in which the rotating drum is divided, because the process of regeneration is made the same regardless of the specifications of the waste ascon, the waste ascon of small particles inside the rotating drum There is a problem that can be melted in.

In other words, the molten waste ascon was melted and coated in the rotating drum, so that it was difficult to produce recycled asphalt (asphalt concrete). There was also a need to frequently clean the inside of the rotating drum.

Disclosure of the Invention It is an object of the present invention to provide a waste ascon regenerating apparatus which corrects the above-described problems, and puts raw materials having different specifications into each rotating drum to be regenerated, thereby improving quality and mass production of recycled ascons.

In order to achieve the above object, a plurality of hoppers for storing the raw material; A plurality of rotating drums installed corresponding to the transfer rails connected to the outlet of the hopper; Heating means installed on one side of the rotating drum; It is composed of a sorting means installed at the outlet of the final rotating drum of the rotating drum.

On the other hand, the waste ascon injected into the sixth hopper 16 is discharged by a predetermined amount so as to achieve an appropriate ratio and is injected into the other side of the grinding mixing rotating drums 30a '' and 30b ''.

In addition, by mixing the waste ascon and the new aggregate introduced into the grinding mixing rotary drum (30a '', 30b '') is made by a heating means 40 is heated to a suitable temperature.

At this time, the temperature of the heating means 40 is heated to 180 ~ 200 ℃ so that the fluid component contained in the waste ascon does not burn.

In step 4, the mixture of the waste ascon and the new aggregate, which is ground, mixed and heated in the grinding mixing rotary drums 30a '' and 30b '', is transferred to the mixer mixing rotary drum 30c '' by the transfer means 80. Hauled up).

In step 5, the waste ascon and new aggregate mixtures conveyed from the conveying means 80 are mixed with an appropriate amount of asphalt oil and mixed in the mixer mixing rotary drum 30c ″.

At this time, the asphalt oil is essentially added to obtain a qualitatively superior product in the process of regenerating waste ascon and reducing it to asphalt.

In addition, by mixing the waste ascon and the new aggregate introduced into the mixer mixing rotary drum (30c '') is made a step of heating to a suitable temperature by the heating means 40.

At this time, the temperature of the heating means 40 is heated to 150 ~ 170 ℃ so that the fluid component contained in the waste ascon does not burn.

In step 6, the asphalt produced in the mixer mixing rotary drum (30c ″) is sorted by the sorting means 90 as a recycled ascon below a certain size and bad ascon above a certain size.

As described above, the present invention comprises a plurality of hoppers, a rotating drum, a heating means, a conveying means, and a sorting means, wherein raw materials having different specifications from the plurality of hoppers are separately added to the plurality of rotating drums, and recycled ascon. By adjusting the aggregate content of the recycled ascon quality and mass production can be achieved.

In addition, the raw material according to the standard is separated into a plurality of the rotating drum, it is possible to separate production of the waste ascon recycling plant for surface and substrate.

In addition, a plurality of the rotating drum may achieve thermal efficiency and quality improvement by using the heating means having different amounts of heat.

That is, the first rotating drum of the plurality of the rotating drum is a new aggregate and asphalt lumps are put into the waste ascon lumps are not oxidized even if the 180 ~ 200 ℃ heat is melted in a fast time and the new aggregate is sufficiently heated .

In addition, the last rotating drum of the plurality of the rotating drum is the asphalt oil of the small particles are put into the asphalt oil is not oxidized even if 150 ~ 170 ℃ heat can be achieved to improve the quality of the recycled asphalt.

On the other hand, in the second embodiment, a plurality of the rotating drums are arranged in series, and raw materials having different specifications are separated from the plurality of the hoppers into the plurality of the rotating drums, and the aggregate content of the recycled asphalt concrete is adjusted to control the quality and productivity of the recycled asphalt concrete. This is further improved.

In addition, in the third embodiment, a plurality of the rotating drums are arranged in parallel and in series, and raw materials having different specifications are separated from the plurality of the hoppers into the plurality of the rotating drums, and the aggregate content of the recycled asphalt concrete is adjusted to control the quality of the recycled asphalt concrete. And productivity is further improved.
