HEATED RECYCLING ASPHALT MANUFACTURE METHOD [0002]

More particularly, the present invention relates to a method of manufacturing a heated recycled asbestos mixture, and more particularly, to improve the structure of a waste asbestos crusher to improve productivity, and to efficiently treat and reuse dust generated when crushing and transferring waste asbestos, And more particularly to a method of producing a heated-type regenerated asbestos mixture.

In general, the recycled ascon is a concrete made by recycling waste asbestos. Recently, research on recycled ascon has been continuously carried out to solve environmental problems.

One of the methods for producing recycled ascon is a method for producing recycled ascon by heating and mixing waste ascon, new asbestos, asphalt, filler and the like, which is referred to as a method for producing a heated recycled ascon mixture.

An example of a method for producing a heated-type regenerated asbestos mixture is disclosed in Korean Patent Registration No. 10-1314134. This conventional patent discloses a regeneration system including a mixer, a new aggregate feeder for feeding fresh aggregate to a mixer, a recycled aggregate feeder for feeding recycled aggregate to the mixer, a filler feeder for feeding the filler to the mixer, and an asphalt feeder for feeding the asphalt to the mixer. Thereby starting the ascon production apparatus. Therefore, new aggregate, recycled aggregate, filler, and asphalt are put into a mixer and mixed to produce a recycled ascon.

However, the process for producing waste recycled asbestos mixture disclosed in the above-mentioned prior art does not disclose a process for obtaining waste asbestos. That is, in order to produce a heated recycled asbestos mixture, it is necessary to obtain waste asbestos and crush it to a predetermined size, and there is no description and description thereof. In addition, there is a disadvantage that the surrounding environment is contaminated because there is no process for treating dust generated when crushing or transferring waste asbestos and new asbestos.

Referring to FIG. 1, a method of manufacturing a heated type recycled asbestos mixture according to the present invention basically prepares a mixer 10. Then, the waste asbestos stored in the waste asbestos cold bin 20 is heated by the waste asbestos heating unit 21, and the waste asbestos is transferred to the waste aspheric weighing supply unit 23 through the waste ascon bag 22, And supplies the metered amount to the mixer (10). The new aspheric material stored in the new aspheric material bin 30 is heated by the new material ascon heating unit 31 and then transferred to the new material aspheric measurement unit 33 through the transfer unit 32. Then, ) To the mixer 10, A predetermined amount of asphalt is supplied to the mixer 10 through the asphalt supply unit 40 and a filler is supplied to the mixer 10 through the filler supply unit 50. The mixer 10 is operated to mix waste ascon, new asbestos, asphalt, and filler together to produce a heated room recycled asbestos mixture. Of course, since these steps are typical operations, well-known techniques can be applied, and therefore detailed description will be omitted.

In addition, the present invention further comprises the step of delivering and crushing waste asbestos to the waste asbestos cold bin 20. That is, after the waste ascon is transported to the work site through the transporting unit 60, the waste asbestos transported is passed through the sorting unit 61 to sort and separate the soil and foreign matter. When the soil and foreign matter sorting operation is completed, the waste asbestos is transported to the crushing unit 62, and the crushed waste ascon is introduced into the waste asbestos crusher 100 and crushed to 13 mm or less. do. Here, the transporting unit 60 and the sorting unit 61 may be manufactured by using a well-known product, and a detailed description thereof will be omitted. However, it is preferable that the waste asbestos crusher 100 employs an apparatus having a function of crushing waste asbestos, so that the following apparatus can be applied.

In addition, the dust collecting unit 70 collects the dust generated when the waste asbestos is crushed, so that the waste can be reused. At this time, the dust generated when the waste asbestos is transferred to the waste asbestos metering supply unit 23 through the waste asbestos transfer unit 22 is also guided to the dust collecting unit 70 and collected, and the new asbestos is transferred to the new asbestos transfer unit 32 The dust generated when the dust is transferred to the new material ascon measuring unit 33 is also guided to the dust collecting unit 70 and collected. The dust collected in the dust collecting unit 70 is separated from the dust separating unit 71, and some of the dust is immediately reused and the remaining dust is stored separately for other purposes. That is, dust in a powder form is guided to a separate collecting part 72, and dust in a form larger than powder is guided to the mixer 10 so that it can be used as a filler. Here, the dust collecting unit 70 and the dust separating unit 71 may be manufactured using known products, and thus a detailed description thereof will be omitted.
