Description

Method for separating asphalt and aggregate using a wosted ascon}

The present invention relates to a method for separating asphalt and aggregate using waste ascon paving roads and plazas, and using waste ascon to separate and recycle waste asphalt used and discarded in asphalt, aggregate and sand. It is about.

As the economy grows and the demand of various industries expands, the quantity of waste ascon pavement that has been discarded after being discarded for use is increased day by day, and it is difficult to dispose of it as landfill or unauthorized dumping. As a matter of fact, the present invention is also called ascon as asphalt and aggregate and sand, so that they can be recycled again.

In order to solve the above problems, the present invention is to separate and reduce ascon to the original raw materials, asphalt, aggregate, and sand so that they can be completely separated to be recycled again.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1st process

Ascon crushed product (3) crushed into a suitable creeper into the melting furnace (1) through the inlet (3) and the oil burner (4) of the ash through the combustion chamber (5) to enter the melting furnace (1) 150 ℃ ~ 180 Ascon lysate at 占 폚 is obtained and transferred to the inclined filtration network 9 of the primary separation tank 8 through the dissolved ascon conduit 7.

In the washing process, washing without applying heat takes a lot of time, so a small amount can be carried out at the time of production. In addition, the dust is collected and treated through the dust collecting facility (6).

2nd process

Nozzle of the dissolution washing agent circulation supply pipe (10) with a cooled dissolution cleaning agent (13) made of methylene chloride, forluene, or chemicals on the dissolving ascone transferred on the gradient filtering network (9) of the primary separation tank (8) ( 11) by strongly quenching and rinsing for 5 to 10 seconds and releasing heat at 150 ° C to 180 ° C during the emanation of heat from 150 ° C to 180 ° C. ) And the asphalt (14) does not go down the inside of the primary separation tank (8) and is transferred to the next process through the molten asphalt transfer pipe (16). The nozzle 11 is dropped by the blower 10-1 and dropped to the receiving container 10-2 by the operation of the air, cooled by the cooling wind, and then acted by the conveying and high-pressure pump 17-1. In the high pressure spray of the cleaning agent will act.

3rd process

The aggregate 12 is transferred to the aggregate water washing tank 18 by the belt comb 15 to wash the water, and then the first sorting room 19 having the size of the mesh is enlarged step by step. While passing through the three fronts of the room 21 to be distinguished by the aggregate size.

4th process

Asphalt seafood transported to the secondary separation spat cylinder 22 through the dissolving asphalt conveying pipe 16 is filtered by particles of 0.07 mm or less in the dissolving asphalt filtration filter 28 and the extrusion rod of the pressure cylinder 24 ( 25, the pressing plate 23 is pressed by the compression action of the pure asphalt 14, the asphalt collecting tank through the asphalt discharge pipe 26

Collected by the (27) and the sand between the platen 23 is left 29 to open the platen 23 and collect the sand separately.

As described above, the present invention efficiently removes and separates asphalt, aggregate, and sand contained in ascon as a dissolving washing agent, thereby reducing the original material to asphalt, aggregate, and sand, thereby recovering the complete recycling effect. It completely solved various problems that were considered for disposal.

Claims (1)

Ascon crushed product (3) is put into the melting furnace (1) and enters the melting furnace (1) through the fire line combustion chamber (5) of the oil burner (4) to obtain ascon dissolved water of 150 ℃ ~ 180 ℃ to dissolve the ascon transfer pipe (7) dissolving the rinse washing agent on the dissolving ascone conveyed on the inclined filtration network (9) of the primary separation tank (8) through the inclination filtration network (9) of the primary separation tank (8) The aggregate 12 is transported to the belt conveyor 15 by the nozzle 11 of the cleaning agent circulating supply pipe 10 and is transported to the belt conveyor 15, and the asphalt 14 and the dissolution washing agent 13 are the primary separation tank 8.
