The present invention relates to a circulating ascon indirect heating device for collecting waste asphalt packed on the road, mixing circulating ascon classified in size for surface layer and substrate, and mixing it with new aggregate and mixing it with AP oil. The circulating ascon which retains the characteristics of asphalt concrete (including aggregate, stone powder, AP oil, sand, etc.) as it is, is heated indirectly by heating the new material before mixing the AP oil and new material. It relates to a circulating ascon indirect heating device for mixing and mixing circulating ascon at a certain ratio and allowing AP oil to be mixed.

In general, asphalt paved roads have different sizes of aggregates mixed with AP oil depending on the surface layer and substrate.

Therefore, as described above, in case of repairing or repairing for a long time, the paved asphalt had to be separated from the road surface and disposed of.

As the above-mentioned waste asphalt has a great impact on environmental pollution, although the government has made various efforts to promote the recycling business from private operators, the construction company that paves the asphalt road recycles the waste asphalt or waste asphalt. There is a situation to avoid using aggregate.

That is, when new aggregates and recycled aggregates are used in a proportion, that is, when recycled aggregates are mixed with new and AP oils to produce ascon, aggregates recycled from waste ascon are not perfect new aggregates, but contain AP oil. In addition, several aggregates are mixed and mixed, and since the quality of the malignant aggregates is degraded due to long use, the porosity increases as well as the quality of the new ascon when mixing with new aggregates.

Therefore, suppliers or contractors who supply new materials do not trust the use of recycled aggregates that recycled waste asphalt, thereby avoiding the use of waste, resulting in an increase in waste asphalt and waste asphalt, resulting in enormous capital costs for disposal. It damages and adversely affects the surrounding environment.

Particularly, in the case of suppliers supplying new goods, even if the recycled aggregate recycled waste ascon is used, if the quality of the product is guaranteed, it can not only save a lot of costs, but also collect the profits generated from collecting the waste asphalt and produce new goods. It can generate huge profits from the raw material cost which is saved while saving the profits of both the environment, supply and profits. Therefore, it is necessary to request that the products produced by recycling waste ascon be used in manufacturing new materials. It is true.

In accordance with such request, the patent application No. 2005-0010664 filed by the applicant on February 4, 2005, separates and classifies the aggregated waste ascon for surface and substrate, and reproduces it as circulating ascon and regenerates it with new materials. It can be mixed with AP oil.

However, considering the reality of new ascon companies that want to utilize circular ascons, there is a problem that they cannot utilize circular ascons because they are not financially sufficient to support a large amount of funds for securing additional yard space or facility investment. .

The present invention devised to solve the above problems is to produce the circulating ascon directly as a new material without producing the circulating ascon directly to the yard, so that the supplied circulating ascon is indirectly heated to an appropriate temperature when the new material is heated, and then circulated with the new material. Its purpose is to allow ascone to be mixed and mixed with AP oil.

In the above-mentioned purpose, in the circulating ascon indirect heating apparatus which collects waste asphalt packed on the road, mixes circulating ascon classified into the size for surface and substrate, and mixes it with new aggregates and mixes it with AP oil. A new aggregate receiving portion 101a of a predetermined size having a closed shape at both ends is formed to have a cylindrical outer diameter to accommodate the new aggregate, and at one end, the first inlet 103 is coupled to open and close. And a built-in drum 101 formed at the other end of the inner discharge port 105 to which the second opening and closing door 104 is opened and closed. Both ends are closed in a shape that is spaced apart from the outer diameter of the built-in drum 101 by a predetermined distance, and at one end, an external inlet 108 is formed to which the third opening and closing door 107 is opened and closed to form a predetermined amount of circulating ascon. An exterior drum 106 formed at an end spaced from the interior drum 101 and having an outer outlet 110 coupled to the other end thereof so that the fourth opening and closing door 109 can be opened and closed; A burner 111 installed at a predetermined position of the internal drum 101 to provide a flower garden directly to the new aggregate receiving portion 101a of the internal drum 101; A heat insulating material 112 which is wound around the outer diameter surface of the outer drum 106 to prevent the internal temperature of the inner drum 101 and the outer drum 106 from being lowered; It is achieved by a circulating ascon indirect heating device comprising a rotating means of the outer drum for rotating the outer drum 106 and the inner drum 101.

Here, the rotating means of the outer drum, the shaft 114 is installed in the outer drum 106 to be positioned at the center of rotation of the outer drum 106 and rotatably fixed to the mounting mount 113; An interlocking gear 115 installed at an outer diameter of the outer drum 106; The drive gear 116 meshed with the interlocking gear 115 is arranged at the end of the drive shaft, and the drive gear 116 of the drive motor 117 is installed at a predetermined position of the external drum 106 mounting stand 113.

In addition, the inner diameter of the inner drum 101 and the outer diameter of the outer drum 106 is bolted to further include a plurality of support parts 118 to support the separation space of the inner drum 101 and the outer drum 106 desirable.

Hereinafter, with reference to Figures 1 and 2 attached to the circulating ascon indirect heating apparatus according to the present invention.

First, Figure 1 is a cross-sectional view showing the structure of the circulating ascon indirect heating device (dryer) according to the present invention.

As shown in FIG. 1, the indirect heating apparatus according to the present invention has a built-in drum 101 for heating the new aggregate and is installed in the interior of the exterior drum 106. Both ends are closed form new aggregate receiving portion (101a) is provided, one end of the both ends of the first opening and closing door 102 is formed with an inner inlet 103 coupled to open and close, the other end is heated new aggregate The second open door is coupled to the inner discharge port 105 to be opened and closed.

Here, the first opening and closing door 102 and the second opening and closing door 104 may be a coupling structure by the hinge coupling and the hinge, bolting coupling to completely block the new aggregate receiving portion (101a) of the internal drum 101 The present invention is not limited to this as may be made.

In addition, the outer drum 106 is installed as shown in FIG. 1 to be spaced apart by a predetermined distance from the inner diameter of the inner drum 101. Accordingly, the outer drum 106 also has an inner diameter of the outer drum 106 and the inner drum 101. Since a predetermined space is secured between the outer diameters of the cylinders, the circulating ascon can be accommodated in this space.

Both ends of the exterior drum 106 are also closed with both ends, such as the interior drum 101, but at one end, an outer inlet 108 coupled to the third opening and closing door 107 is provided, and the other end is indirectly heated. An outer outlet 110 through which the circulating ascon is discharged is provided, and the fourth opening and closing door 109 is coupled to open and close.

On the other hand, once the predetermined position of the internal drum 101 is provided with a burner 111 to directly provide a flower garden to the new aggregate receiving portion (101a), the new aggregate is received by the thermal power generated by the burner (111) The new aggregate accommodated in the portion 101a is heated, and normally, the burner 111 is heated with 350 ° C heat to supply thermal power until the new aggregate is heated to 180 ° C.

Therefore, when the inside and the outside diameter of the interior drum 101 is heated by the thermal power supplied to the interior drum 101, the heat is transferred to the inside of the exterior drum 106 installed a predetermined distance away from the interior drum 101. Accordingly, as the circulating ascon injected into the external drum 106 is also heated together, the temperature is increased.

Here, the circulating ascon is not heated as much as the new aggregate is heated to increase the temperature, but since the circulating ascon contains the existing components of AP oil and asphalt as it is, it is not necessary to heat up to the extent that the new aggregate is heated.

On the other hand, the outer diameter of the outer drum 106, the inner drum 101 and the outer drum 106 in order to maintain the temperature inside the outer material 112 is preferably outer, so as to the outer material 112, the outer outer In order for the circulating ascon and new aggregate contained in the external drum 106 and the internal drum 101 to be efficiently heated, the external drum 106 and the internal drum 101 are supplied with a heat source from the burner 111 at a predetermined speed. Since it is preferable to have a continuous rotation operation, the following describes the rotating means of the external drum 106 for rotating the external drum 106 and the internal drum 101.

The rotating means of the outer drum 106 is penetrated by the inner drum 101 so as to be located at the center of rotation of the outer drum 106, and the shaft 114 is rotatable to the mounting mount 113. Fix as shown in FIG.

By transmitting the power to the interlocking gear 115 through the drive gear 116, the shaft 114 and the outer drum 106 rotatably installed on the mounting stand 113 to the power of the drive motor 117. It will rotate.

In addition, the rotating means of the outer drum 106 is a pair of rotary rollers (not shown) in the lower portion of the outer drum 106 in a state in which the shaft 114 is not mounted on the outer drum 106 and the inner drum 101. (Not shown) to allow the rotating roller to support the outer drum 106 and at the same time cause the rotating roller to be rotated by the drive motor, thereby allowing the outer drum 106 to rotate.

On the other hand, the outer diameter of the inner drum 101 and the outer diameter of the outer drum 106 by bolting a plurality of support parts 118 to secure the space between the inner drum 101 and the outer drum 106, the circulation is accommodated It is preferable to prevent the shape and shape from being changed by the weight of ascon and new aggregate.

The circulating ascon indirect heating device of the present invention having the above-described structure is introduced with the new aggregate into the internal drum 101 as described above, and the circulating ascon is introduced between the external drum 106 and the internal drum 101, thereby The interlocking gear in which the internal aggregate 101 and the external drum 106 are integrally wound around the outer diameters of the driving motor 117, the drive gear 116, and the external drum 106 while heating the new aggregate of the drum 101. By rotating by the 115, the heat of the burner 111 applied to the internal drum 101 is diffused into the external drum 106 so that the circulating ascon is accompanied by heating.

When the new aggregate is heated to the desired temperature as described above, the new aggregate is discharged to the outside through the inner outlet 105, the artificial aggregate may be taken out of the internal aggregate through the outlet, the mounting stand 113 By installing the shaft 114 and the inner drum 101 and the outer drum 106 to be inclined slightly toward the inner outlet 105 and the outer outlet 110 side, the second opening door 104 or at the same time as heating and rotation Opening the fourth opening and closing door 109 may also be preferable to allow the new aggregate and circulating ascon naturally discharged to the outside.

When the new aggregate is heated to about 180 ° C, the circulating ascon which is indirectly heated is heated to about 150 ° C, and the discharged new aggregate is classified into the surface layer and the base layer and then introduced into the mixer (Mixer), at which time, to the outer outlet 110. The discharged circulating ascon is also mixed with the AP oil according to the type of new aggregates classified, and the mixed ascon can be shipped immediately.

As described above, the present invention has a dual structure of a new material dryer (heater), and heats the new aggregate to the internal drum and indirectly heats the internal drum to the low temperature of the circulating ascon. Due to this, it was possible to overcome the problem of deterioration of the packaging quality when mixing, and by mixing the heated circulating ascon and new aggregate to be mixed with AP oil in the mixer, the quality deterioration can be prevented in advance. In case of companies that cannot expand their facilities due to surrounding complaints, they do not have to spend a lot of money to use the circulating ascon again, replacing the new dryer with the circulating ascon indirect heating device according to the present invention, thereby reducing the total cost of additional facilities. At the same time, it is possible to obtain the effect of saving raw materials.
