BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dryer for a recycled asbestos plant, and more particularly, to a dryer for a recycled asbestos plant, which can be agitated while minimizing fusion of recycled ascon by a blade installed in a cylindrical body of the dryer .

Ascon is a term used to reduce asphalt concrete. It refers to a mixture of asphalt and sand, gravel, dust and additives, and is widely used for road pavement and parking lots. Generally, it contains about 900 ~ 950kg of aggregate (gravel, sand, dust, filter) and about 50 ~ 100㎏ of asphalt component (additive) based on 1,000kg of asconone.

As shown in Fig. 1, an ascon plant for producing such an ascon is made up of a cold bin 1 having a plurality of aggregate loading hoppers into which aggregate is charged, an aggregate dryer 1 for heating and drying the aggregate fed into the cold bin 1, (2), a sorter (3) for sorting the heat-dried aggregate into five size classes according to the particle size, an aggregate input controller (3) for selecting the aggregate to be moved to the mixer, 4), an elevator 5 for moving the aggregate from the aggregate dryer 2 to the sorter, a dust feeder 6 for supplying the dust, an additive feeder 7 for feeding the additive, and dust, And a mixer 8 for producing an ascon. A bag filter 9 including a cyclone for collecting dust generated in the dryer 2 and a stack for discharging the collected air to the atmosphere is constituted.

On the other hand, the roads packed with the ascon can be deformed or damaged due to the passage, weight and aging of the vehicle, and a large amount of waste ascon is generated during the repairing process.

Fig. 2 shows a schematic configuration diagram of the regenerated asbestos dryer in the regenerated ascon plant. In addition to the constitution of the ascon plant, the constitution for regenerating the used ascon is similar to that of the regenerated ascon reactor. An elevator 1c for feeding the regenerated asphalt poured into the regenerated asbestos hopper 1a to the recycled asbestos dryer 1b heated and dried and the regenerated asphalt poured into the regenerated asbestos hopper 1a to the regenerated asbestos dryer 1b do. Through the above configuration, the regenerated asphalt is supplied to the mixer 8 (see FIG. 1) in an appropriate amount and mixed with the aggregate and the additive.

In this constitution of the ascon plant, the regenerated asbestos dryer 1a comprises a cylindrical body, a driving means for rotating the cylindrical body, and a burner.

Japanese Patent Application Laid-Open No. 10-1012657 discloses a dryer for regenerated asbestos. The dryer for recycled asbestos according to the related art has a heat insulating cylinder having an inlet for charging the recycled ascon and an outlet for discharging the recycled ascon, the inlet being inclined higher than the outlet, and a heat insulating cylinder disposed at one side of the heat insulating cylinder close to the inlet A burner for generating a flame inside the heat insulating cylinder, a communication pipe installed inside the heat insulating cylinder for transferring the regenerated asphalt to surround the flame of the burner and to prevent the direct contact of the flame with the regenerating asphalt introduced through the inlet And a plurality of blades provided on an inner circumferential surface facing the other side of the heat insulating cylinder at a combustion passing interval and driving means for rotating the heat insulating cylinder.

FIG. 2A is a perspective view showing a structure of a blade installed inside the heat insulating cylindrical body. FIG.

Referring to FIG. 2A, the vane 1d installed inside the heat insulating cylinder according to the related art has a plate shape bent in a direction opposite to the rotating direction. The blade having such a structure moves the regenerated ascon in accordance with the rotation of the adiabatic cylinder and drops it from the upper part of the adiabatic cylinder to stir the regenerated ascon.

However, in the bent plate-shaped blades, the additive of the recycled ascon is melted and adhered to scale in the rotating direction. There is a problem that the amount of the recycled ascon to be dropped falls as the scale is generated and the stirring efficiency is lowered.

In addition, when the wing is provided on the entire inner length of the heat insulating cylindrical body, the wing disposed close to the burner side has a problem that scale generation is increased.

KR 10-1012657 B1 2011. 01. 27.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a dryer for a recycled asbestos plant capable of preventing the scaling due to the alternation of recycled ascones.

Another object of the present invention is to provide a dryer for a recycled asbestos plant which can increase stirring efficiency.

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

The present invention relates to a dryer for a recycled asbestos plant, which can be agitated while minimizing the adhesion of recycled ascon by a wing installed in a cylindrical body in a dryer used in a recycled ascon plant.

Fig. 3 shows a configuration diagram of a regenerated asbestos plant to which a dryer for a regenerated asbestos plant according to the present invention is applied.

3, the recycled asbestos plant to which the dryer for recycled ascon plant according to the present invention is applied includes a recycled ascon cold bean 10, a recycled ascon elevator 20, a recycled ascon dryers 30, a storage silo 40 , A trolley (50), and a duct (60).

The recycled ascon cold bean 10 is collected and stored, and the recycled ascon is carried and stored. The supplied recycled ascon is collected from the pavement, and may include a process of crushing or crushing the mass before being injected into the recycled ascon cold bin 10.

The regenerating ascender elevator 20 vertically moves the regenerating ascender stored in the regenerating ascender cold bin 10 so that the regenerating ascender is inserted between the regenerating ascender elevator 20 and the regenerating ascender cold bin 10, A conveying conveyor may be further provided for feeding the toner to the developing unit 20. The regenerated ascender elevator 20 can be replaced with a belt conveyor or the like according to the arrangement structure.

The regenerated asbestos dryer 30 is for heating and drying the regenerated ascon, and is for improving the quality of the ascon by removing the moisture contained in the regenerated ascon as the regenerated ascon is heated. That is, when moisture is contained in the regenerated asphalt, the water contained in the regenerated asphalt forms a water film on the surface of the aggregate so that the additive can not be adhered to the regenerated asphalt, which degrades the quality of the asphalt. Therefore, the recycled ascon used in the ascon plant must undergo a drying process.

The storage silo (40, silo) is a hopper shape in which the recycled ascon stored in the recycled ascon-dryer (30) is stored.

The transfer trolley 50 is a device for transferring the recycle ascon stored in the storage silo 40 to the mixer 80. At this time, the amount of recycled ascon used in the conveying trolley (50) is conveyed in a certain amount according to the mixing ratio with the aggregate.

The duct 60 collects dust generated in the cylindrical body of the regenerating dryer 30 and transfers the collected dust to the storage silo 40.

That is, the duct 60 includes a suction pipe and a suction blower. At this time, one end of the suction pipe is connected to the inlet side of the cylindrical body, and the other side is connected to the storage silo 40. The dust generated in the cylindrical body by the operation of the suction blower is sucked by the suction pipe and discharged to the storage silo 40. [

On the other hand, regenerated asbestos is specified to be mixed with aggregate (new aggregate).

Accordingly, the recycled asbestos plant can be installed in combination with the ascon plant for processing the new aggregate. Here, the ascon plant may include a cold bin 70, an aggregate dryer 72, a selector 74, an aggregate elevator 76, and a mixer 80.

The cold bean 70 is filled with the conveyed aggregate (new aggregate), and the aggregate may be composed of gravel, crushed stone, and the like.

The aggregate dryer 72 is for heating and drying the aggregate material charged into the cold bean 70, and is composed of a cylindrical body, a burner, and a driving means although not shown. At this time, the cylindrical body is provided downwardly inclined from the inlet to the outlet to the outlet, and the burner is provided to the outlet. In addition, the driving means rotates the cylindrical body, and the aggregate put into the inlet through the rotation is rotated while being stirred inside the cylindrical body and moved to the outlet side. At this time, the inside of the cylindrical body is maintained at a high temperature according to the operation of the burner, and the agitated material agitated in the cylindrical body by the high temperature is heated and dried.

Here, the reason for heating the aggregate is to remove moisture contained in the aggregate. When moisture is contained in the aggregate, the moisture contained in the aggregate forms a water film on the aggregate surface, thereby preventing the additive from adhering to the aggregate, which causes deterioration of the quality of the ascon. Therefore, the aggregate used in the ascon is subjected to a drying process.

A moving device may be provided between the cold bin 70 and the aggregate dryer 72, such as a conveyor or an elevator for moving the aggregate. At this time, the moving device may be provided with a screen for selecting the size of the aggregate. The screen selectively discharges gravel, sand and soil of a predetermined size or less that is not suitable for use in the ascon.

The sorting unit 74 classifies the aggregate heated and dried in the aggregate dryer 72 by the particle size, and the aggregate is classified into five size classes by the particle size through the separator 74.

The aggregate elevator (76) vertically feeds the aggregate heated and dried in the aggregate dryer (72) to the separator (74). 3, the aggregator elevator 76 for vertically conveying the aggregate to the separator 74 is illustrated as having a structure in which the mixer 50 is disposed on the lower side of the sorter 30. However, The aggregate elevator 76 can be replaced with a conveying conveyor or the like depending on the arrangement position of the separator 74 and the mixer 80. [

The mixer 80 mixes dust, additives, and aggregate to produce an ascon. Here, the dust is supplied from the dust feeder, and the additive is supplied from the additive feeder. Also, the aggregate is configured to be introduced into the mixer 80 through an aggregate input amount controller that controls the aggregate to be mixed at an appropriate ratio according to the size among the aggregates selected by the granularity.

In addition, dust, additive, and aggregate that are added and mixed can be configured to detect weight and mix at an appropriate ratio.

Fig. 4 shows a configuration diagram of a dryer for a reclaimed asbestos plant according to the present invention.

The dryer 30 for a reclaimed asbestos plant according to the present invention comprises a cylindrical body 100, a burner 200, a driving means 300 and a firebox 400.

The cylindrical body 100 moves the regenerated asconcone while agitating, and is installed so as to be inclined downward from the inlet 101 side to the outlet 102 side. In the cylindrical body 100, the recycled asbestos injected into the inlet 101 side is moved toward the outlet 102 side in accordance with the rotation operation and is discharged.

The burner 200 is installed on the inlet 101 side of the cylindrical body 100 and supplies heat to the interior of the cylindrical body 100. The burner 100 includes a blower for sucking air and blowing air, a nozzle installed on a side surface of the flow path pipe blown by the blower for supplying fuel, and an ignition device provided inside the tip of the flow path for igniting the fuel .

A first diffusion plate 110 and a second diffusion plate 120 for diffusing heat blown from the burner 200 are installed in the cylindrical body 100.

FIG. 5 is a perspective view of a cylindrical body applied to a dryer for a reclaimed asbestos plant according to the present invention, and FIG. 6 is a sectional perspective view of a cylindrical body applied to a dryer for a reclaimed asbestos plant according to the present invention.

5 and 6, the first diffusion plate 110 is installed inside the cylindrical body 100, and the hot air generated from the burner 200 is directed toward the inner wall of the cylindrical body 100 .

The first diffusion plate 110 has a first support 111 formed at one end thereof on the inner wall of the cylindrical body 100 and the other end protruding toward the center and a second support 111 coupled to the other end of the first support 111, And a diffusion plate 112 on which a curved surface is formed. At this time, the first diffusion plate 112 is positioned at the center of the cylindrical body 100. Here, the first support 111 may be installed in 3 to 4 positions depending on design conditions.

According to the present invention, hot air supplied from the burner 200 is guided to the inner wall side of the cylindrical body 100 by the first diffusion plate 110 to diffuse the hot air.

The second diffusion plate 120 is installed at the rear end of the first diffusion plate 110 (rear side with respect to the traveling direction of the hot air) to collect hot air toward the inner wall of the cylindrical body 100 to diffuse it. The second diffusion plate 120 has a second support 121 formed at one end thereof on the inner wall of the cylindrical body 100 and the other end protruding toward the center of the second diffusion plate 120. The second diffusion plate 120 is coupled to the other end of the second support 121, And a diffusion cone 122 of a cone shape in which a curved surface is formed opposite to the hot air and the front end is cut.

According to the present invention, the hot air supplied from the burner 200 is collected by the second diffusion plate 120, and the collected hot air flows to the outlet side of the cylindrical body 100 while passing through the second diffusion plate 120 And transmitted. In addition, the hot air traveling by the shape of the outer circumferential surface of the second diffusion plate 120 is guided to the inner wall side of the cylindrical body 100 to diffuse hot air.

Accordingly, the hot air supplied from the burner 200 is diffused to the inner surface of the cylindrical body 100, and the diffused heat is again collected and diffused to distribute uniform heat to the entire interior of the cylindrical body 100 , The drying efficiency of the recycled ascon can be increased by heating.

A plurality of vanes 150 are formed in the cylindrical body 100.

The vane 150 stirs the regenerated asphalt which is introduced into the inlet 101 of the cylindrical body 100 and is moved. That is, as the cylindrical body 100 rotates, the regenerated asphalt pellets are loaded and dropped, and the regenerated asphalt pellets are dropped from the upper portion of the cylindrical pellet 100 to stir the regenerated asphalt pellets.

5 and 6, the vane 150 has a pair of frames 151, one end of which is installed on the inner wall of the cylindrical body 100 and the other end of which is protruded to the center and is bent in the direction opposite to the rotation direction And a plurality of crossbars 153 provided between the frame 151 and the frame 151. In addition, an auxiliary frame 155 for preventing deformation of the crossbar 153 is provided at an intermediate portion of the crossbar 153. The vanes 150 configured as described above are alternately installed inside the cylindrical body 100.

Accordingly, as the cylindrical body 100 rotates, the wing 150 moves the regenerated aspheric pellet to move the regenerated asphalt pellet from the upper part of the cylindrical body 100 to stir the regenerated asphalt pellet. Of course, according to the structural characteristics of the vanes 150, a part of the recycled ascones loaded in the vanes 150 may be discharged through the crossbars 153. This discharge, however, leads to an advantage that the wing 150 can be prevented from scaling.

According to the present invention, since the scale generated in the vane 150 can be minimized, the efficiency of stirring can be increased to improve the drying efficiency of the recycled ascon, and the generation of scale can be minimized, Thereby increasing the production of recycled ascon.

Since the hot air provided by the burner 200 is directly transferred to the inlet 101 of the cylindrical body 100, the temperature of the inlet 101 of the cylindrical body 100 is maintained at a relatively higher temperature than the outlet 102 side. Therefore, when the vane 150 is provided over the entire interior of the cylindrical body 100, a high temperature may cause a scale to adhere to the vane 150 by melting the additive contained in the reclaimed ascon.

The wings 150 are alternately arranged on the side of the outlet 102 from the inner middle portion of the cylindrical body 100 and have a predetermined length inside the inlet 101 side of the cylindrical body 100 A step 170 formed in the longitudinal direction of the cylindrical body 100 is provided in each of the rear sides of the two rows of the screws 160 arranged in a circumferential direction A plurality of such devices can be installed.

The stepped portions 180 may be installed on the rear end side of the screw 160 arranged in two rows according to design conditions. That is, the step 160 may be installed at the rear of the screw 160 arranged at the rear end (rear side with respect to the direction of the hot air). At this time, as shown in FIG. 6, the step portion 180 is formed in a shape of an arc having an inner diameter reduced toward the inner side corresponding to the rotating direction of the cylindrical body, and a step is formed at the end.

The first arraying screw 160, the second arraying step 170, the third arraying screw 160, and the third arraying screw 160 are provided in the cylindrical body 100 from the inlet 101 side to the outlet 102 side. The array 170 of steps 170 or a combination of the step 170 and the step 180) and the fifth array of wings 150 are arranged in sequence.

The first diffusion plate 110 is installed between the third arrangement of the screw 160 and the step 170 of the fourth arrangement and the second diffusion plate 120 is installed between the screw arrangement 160 of the third arrangement and the step 5 array.

The driving means 300 rotates the cylindrical body 100. The driving means 300 includes a driven roller that is rotated by receiving a driving force of a motor, not shown in the figure, and a driven roller that is formed on an outer circumference of the cylindrical body 100, And may be constituted by a cylindrical roller which is in surface contact. At this time, a support roller for preventing sliding of the cylinder 100 installed at an inclined position may be installed.

Next, the firebox 400 will be described.

4, the artificial chamber 400 is installed between the cylindrical body 100 and the burner 200 to attenuate the flame generated in the burner 200, so that only the heat is transmitted to the inside of the cylindrical body 100 .

According to the present invention, the flame generated in the burner (200) is attenuated while passing through the flame chamber (400), thereby preventing the flame from entering the inside of the cylinder (100). Accordingly, there is an advantage that the phenomenon that the regenerated asphalt due to flame is fused in the interior of the cylindrical body 100 can be minimized.

The hot air discharged from the aggregate dryer 20 may be supplied to the cylindrical body 100 of the recycled asbestos dryer 80 to be reused according to design conditions.

The internal temperature of the aggregate dryer 72 for heating and drying the aggregate is maintained between 160 and 180 ° C., and the internal temperature of the regenerated asbestos dryer 30 for heating and drying the reclaimed ascon is maintained at 70 to 80 ° C. And dried. Accordingly, the heat discharged from the aggregate dryer (72) can be guided to the recycled ascon dryer (72).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
