Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates generally to the treatment of asphalt materials, and more particularly to the regeneration of existing asphalt paving materials.

[0002]

BACKGROUND OF THE INVENTION Asphalt has long been the material of choice for paving and has been used extensively throughout the world to meet an ever-increasing need for paving. More recently, specifications are specifying the use of recycled asphalt products in an attempt to preserve the materials used in asphalt production. The use of recycled asphalt materials has become more important as existing pavements have been reconditioned, replaced and the disposal of old replaced pavement materials has become more difficult and costly. as a result,
A large amount of old asphalt material has become available for reuse; however, in current practice, such reuse crushes relatively large pieces of old asphalt material as received from the site and then It was limited to mixing the crushed and reduced size renewable asphalt material with new material. Mixing renewable asphalt material with virgin asphalt leads to unstable reactions and undesired levels of pollutants, thus severely limiting the use of renewable asphalt materials .

Five basic methods are currently used for the utilization of renewable asphalt. In the weighing hopper method, unused uncoated aggregate is overheated and then it is added to the renewable asphalt material in the hopper, where the heat is heated fairly rapidly in the hopper. Transferred from wood to renewable asphalt material. As a result, there is a tendency towards unstable reactions at the mixing point, limiting the amount of renewable asphalt material that can be introduced. In the batch plant bucket elevator method, renewable asphalt material is metered into the bucket elevator where heat transfer occurs. Again, the proportion of renewable asphalt material must be limited to eliminate excessive pollutant emissions. Another method uses a co-current type drum mixer which introduces virgin aggregate at the burner end of the drum to superheat it. Renewable asphalt material is introduced downstream near the center of the drum where it is mixed with superheated virgin aggregate and hot gas. Exposure of fine, renewable asphalt materials to overheated aggregates and hot gases results in a rapid flash and, in addition to the release of other hydrocarbons, is a highly undesirable contaminant, "blue smoke" (blue smoke).
The release of e-smoke) will be triggered.
These releases require control, resulting in severe limits on the amount of renewable asphalt product introduced by this method. In a similar procedure, a separate mixing chamber is used in conjunction with a co-current drum mixer to mix the renewable asphalt material with the heated aggregate outside the hot gas stream in the drum. This method allows the introduction of larger amounts of renewable asphalt material without creating blue smoke, but hydrocarbon emissions still need to be addressed.
The use of a countercurrent drum mixer with separate mixing chambers such that the position of the burner is reversed so that the fresh material moves towards the burner while the exhaust gas moves in the opposite direction is Another improvement constitutes that more renewable asphalt materials can be mixed. However, the amount of renewable asphalt material must still be limited to control pollutant emissions. All of the above methods typically require a separate crusher and sieving equipment to size the renewable asphalt material prior to introducing the material into the mixture with virgin aggregate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings and in particular to FIGS. 1 and 2, an apparatus constructed in accordance with the present invention is generally designated by the numeral 10 and is axially positioned between an inlet end 16 and an outlet end 18. It is seen to include an elongated drum 12 having a generally cylindrical wall 14 extending therethrough. Drum 12
Is placed on a base 23 on the platform 20 and is supported by the drum 12 in a corresponding circumferential track (tr).
ack) 24 is mounted on the platform 20 for rotation about a central axis C using a roller assembly 22 which engages the roller assembly 22 in a manner that is now all known in asphalt handling equipment. 26 is driving. Alternatively, a separate chain-sprocket drive mechanism may connect the prime mover 26 to the drum 12. The base 23 is inclined to raise the inlet end of the drum 12 in relation to the outlet end 18. The tilt angle A is kept relatively shallow, and an angle A of about 4 degrees is sufficient for the purposes described below. The angle A is selectively adjusted by adjusting means shown in the form of a wedge 27 which is moved forward or backward by an actuator 28 to adjust the magnitude of this angle A.

A heating chamber 30 is positioned adjacent the outlet end 18 of the drum 12 and includes an inlet end 16 over a first axial portion of the drum 12 from a rear wall 34 to a front wall 36. A cylindrical side wall 32 is included that extends along the drum 12 toward. The burner 4 is mounted on the platform 20 outside the heating chamber 30.
A zero-shaped heating means is attached, which projects through the rear wall 34 into the interior 42 of the heating chamber 30 to provide a heating flame 44 within the interior 42 of the heating chamber 30. . The heating flame 44 is attached to the front wall 36.
It collides with the baffle plate 46. A plurality of breaker members in the form of tubular members 50 are disposed generally parallel to the central axis C between the inlet end 16 of the drum 12 and the heating chamber 30 along a second axial portion of the drum 12. It extends in the axial direction and is circumferentially aligned about the central axis C. The tubular member 50 is supported in the drum 12 by support rings 54 and struts 56.
It is organized into two forms. As shown in FIGS. 3 and 4, each tubular member 50 has an interior 58 that extends axially along its length. The header in the form of a manifold 60 is a tubular member 5 adjacent to the heating chamber 30.
Integral with the zero end, the manifold 60 is integral with the front wall of the heating chamber for connecting the tubular member 50 with the heating chamber 30. Similar to FIG. 1, FIG.
As you can see best, each of the manifolds 60
The two tubular members 50 are connected to each other and each manifold 60 has a single leg 62 connected to the front wall 36 of the heating chamber 30. The interior 58 of each tubular member 50 passes through the interior 64 of each corresponding manifold 60 so that the hot gases generated within the heating chamber 30 pass through the manifold 60 and into the tubular member 50. In contact with the interior 42.

Renewable asphalt material is received from the site in the form of relatively large debris 70, typically a thick section about 1 foot wide, and is fed directly into the apparatus 10 as shown at 71. Large pieces 70 pass through the inlet end 16 of the drum 12 into an infeed conveyor.
d conveyor 72 into the cage assembly 52 provided by the array of tubular members 50. As the drum 12 rotates, the cage assembly 52 likewise rotates about the central axis C,
The large pieces 70 are tumbled within the cage assembly 52 and at the same time crushed so that the renewable asphalt material is transferred from the inlet end 16 to the outlet end 18 of the drum 12.
It is heated by contact with the tubular member 50 of the cage-like assembly as it travels downstream toward. The circumferential spacing 74 between adjacent tubular members 50 is such that the renewable asphalt material 76 once the desired aggregate size is reached.
Are selected to drop out of the cage assembly 52 and into the wall 14 of the drum 12. A preferred circumferential spacing 74 is about 5.0 between adjacent tubular members 50.
8 cm to 10.16 cm (about 2-4 inches) of air gap, this circumferential spacing being about 1.905 cm (about 3/4 inch) within the recycled asphalt material leaving drum 12 at exit end 18. Produce the desired size. An auxiliary bar 78 is attached to some of the tubular members 50, which
It extends circumferentially so that a defined spacing 74 is maintained between all adjacent tubular members 50. The spacing 74 between adjacent auxiliary bars 78 can be adjusted using selectively loosened fasteners 79 that secure the auxiliary bars 78 to the tubular member 50. Renewable asphalt material 76 of the desired aggregate size continues to descend down the wall 14 of the drum 12, assisted by the flights 80 attached to the wall 14 until the material 76 reaches the outlet end 18 of the drum 12. . Further, the material 76 is tumbled on the sidewall 32 of the heating chamber 30,
That is, it is rolled, where additional heat is transferred to the material 76, and the flights 82 attached to the sidewalls 32 help move the material 76 downstream. On the side wall 32 of the heating chamber 30, the inside 4 of the heating chamber 30 is
2 is provided with an access panel 84 that allows selective access to the inner portion 86 of the drum 12 around the heating chamber 30 from the power supply failure and thus the sudden shutdown of the drum 12 and the resulting drum 12. In the case of rotation stop, the mass of the material 76 in the inner part 86 is basically such that it can be removed in the molten state.

The legs 62 of the manifold 60 are tubular members 5
They are circumferentially separated by a distance greater than the distance 74 between zero. Thus, a medium sized debris 88 of renewable asphalt material, which is now smaller than debris 70 but still large compared to what can fall through gap 74, falls between legs 62, It will enter the material mass in the flow 90 of asphalt material leaving the drum 12. After leaving the drum 12,
This stream 90 is passed through a sieve 92 where intermediate size debris 88 is separated and transferred to a return refill conveyor 94. The return replenishment conveyor 94 includes intermediate size debris 88.
To bin 96, and elevator 98 moves medium size debris 88 from bin 96 to feed conveyor 72 and back to drum 12. A stream 90 of desired aggregate size debris of material 76 is delivered through a discharge chute 99 to a delivery conveyor 100 for use. It should be noted that the renewable asphalt material is not exposed to open flames at any time. Further, the introduction of the renewable asphalt material at the inlet end 16 remote from the heating chamber 30 presents the renewable asphalt material at the relatively lower temperature end of the drum 12, where the temperature at which the material exits the material. It gradually rises as it progresses towards the end 18, thus reducing any tendency for harmful pollutants to be overproduced.

In the preferred arrangement, the wall 14 of the drum 12 is comprised of an inner wall 102, an outer wall 104 and an annular thermal chamber 106 therebetween. An elbow-shaped return member 108 is connected between the end 110 of each tubular member 50 and the annular thermal chamber 106, and thus the tubular members 50.
The heated gas passing therethrough from the heating chamber 30 is introduced into the annular heating chamber 106 and the wall 14 of the drum 12 is
The heated gas flowing in the outlet end 1 of the drum 12
The wall 14 is further heated as it moves to the downstream exhaust port 112 which is 8. In this way, heat is conserved and more heat is available for the process. U.S. Pat. No. 4,932,863
To further store heat, as described in the issue,
Insulating jacket 11 circumferentially around drum 12
4 is extended.

A scraper assembly 120 is mounted 4 for reciprocating movement along the cage assembly 52 to prevent the build up of harmful excess asphalt on the tubular member 50. With reference to FIG. 4 as in FIG. 1, the scraper 122 is engaged with the outer surface 124 of the tubular member 50 and is mounted on the cross shaft 126 which is supported by the spindle 128. The spindle 128 is periodically reciprocated in the downstream and upstream directions by the selective activation of the hydraulic cylinders 130 mounted on the bearing base 132 on the platform 20 and activated under the control of the control box 134. Hydraulic cylinder 13
At zero start-up, scraper 132 rests on outer surface 124 of tubular member 50 and travels along this surface to scrape off excess asphalt and generate debris of renewable asphalt being tumbled within cage assembly 52. 7
Surface 124 will remain free to transfer heat to zero. The tubular member 50 is preferably shown in FIG.

40 is a motor for selecting the rotation speed of the drum 12.
6 is operated to control the rotation speed. A temperature sensor 142 in the heating chamber 30 is connected to a control console 140, which in turn controls the burner 40 to maintain the temperature in the interior 42 of the heating chamber 30 at a selected level. Further, by operating the actuator 28, the selected pitch of the drum 12 is controlled by the control console 140. In addition, the console 140 controls the operation of the scraper assembly 120. In particular,
The angle A is set to about 3-6 degrees, the temperature inside the heating chamber 30 is in the range of about 815.5 ° C to 1093.3 ° C (about 1500-2000 ° F), and the drum 12
The rotation speed of is within the range of about 5 to 7 rotations per minute. The temperature of the recycled asphalt material exiting at the outlet end 18 of the drum 12 is about 93.3 ° C-121.1 ° C (about 200-250 ° C).

It is mounted on the platform 220 for rotation about a central axis CC by a roller assembly 222 which mates with a corresponding circumferential track 224 mounted on a drum 23 and mounted on the drum 212. The roller assembly 222 is driven by an electric motor 226. These are all the same as those described for the apparatus 10. Alternatively, the electric motor 226 may be coupled to the drum 212 by a separate chain sprocket drive. The base plate 223 is tilted to raise the inlet end 216 of the drum 212 with respect to the outlet end 218. The tilt angle is adjustable to be kept at a relatively small value as described for the device 10.

In communication with the interior 242 of 60, the hot gas in heating chamber 230 travels through manifold 260 to tubular member 250.

Renewable asphalt materials are typically about 1
Received from the site in chunks of relatively large debris over ft and fed directly to device 200 as shown in section 271. The large debris 270 is 215 inside the drum 212.

Cage assembly 252 as it progresses downstream toward 18
It is crushed and heated by the contact with the tubular member 250.
The circumferential spacing between adjacent tubular members 250 is such that when the desired aggregate size is reached, the renewable asphalt material 276 falls from the cage assembly 252 and all of the drum 212 as described for device 10. Wall 21
Choose to hit 4. The desired aggregate size of the renewable asphalt material 276 is assisted by a scraper 280 secured to the wall 214 until the renewable asphalt material 276 reaches the outlet end 218 of the interior 215 of the drum 212.

The legs 262 of the manifold 260 are circumferentially spaced a distance greater than the spacing between the tubular members 250. That is, in this case, it remains smaller than the debris 270 but still larger than the asphalt material that can fall through the spacing between the tubular members 250.

In this way, heat is retained and more heat is available for processing. Insulating jacket 314 extends circumferentially around drum 212 and further retains heat as described in U.S. Pat. No. 4,932,863.

Recycled asphalt material is never always exposed to direct flame. Further heating chamber 23
The introduction of the renewable asphalt material at the inlet end 216 farther from zero provides the cooler end of the drum 212 with the renewable asphalt material. The temperature is gradually increased as the material travels toward the outlet end 218, reducing the tendency for excessive harmful pollutants to form. However, during processing, the interior 215 of the drum 212
Hazardous contaminants generated in the device are treated in the apparatus 200 as described below.

Volatile contaminants emitted from the renewable asphalt material during processing in apparatus 200 are treated by oxidizing these contaminants in volatile organic compound oxidizer 320. To this end, volatile contaminants are oxidised from the interior 215 of the drum 212 by means of a gas conduction device formed by a manifold 322 and a duct 324 located adjacent the outlet end 218 of the interior 215 of the drum 212. It leads to the device 320. Duct 324
Is a manifold 322 and a volatile organic compound oxidizer 32.
0 around the outer periphery of the inlet end 3 of this oxidizer 320
28 extends to and communicates with a space chamber 326 extending at 28. The blower 330 has the inner portion 2 of the drum 212.
Volatile contaminants are sucked from 15 through the manifold 322 and the duct 324, and these contaminants are sent into the space chamber 326 through the pushing hole 322 and into the volatile organic compound oxidation device 320.

Volatile organic compound oxidizer 320 is a device well known in the contaminant management arts and acts in response to heat to oxidize volatile contaminants delivered from interior 215 of drum 212. By inserting the device 320 between the burner 240 and the heating chamber 230, the burner 240 produces the heat necessary to operate the device 320, making the use of the device 320 economical and practical. Device 32
During the oxidation of the contaminants within 0, additional heat is generated by the oxidation reaction. If the heat becomes too strong to be safely introduced into the heating chamber 230, the volatile organic compound oxidation device 3
20 and the heating chamber 230 by using the cooling means inserted between the volatile organic compound oxidizing device 320 and the heating chamber 23.
Decrease the temperature between zero interior 242. The air distribution means consisting of the space 340 is attached to the volatile organic compound oxidizer 320, is located adjacent to the inlet end 234 of the heating chamber 230 and communicates with the interior 242 of the heating chamber 230 through the hole 342. The blower 344 pushes atmospheric air into the space 340 and distributes it into the volatile organic compound oxidizing device 320 and the inside 242 of the heating chamber 230 to distribute the heating chamber 2
Lower the temperature at the inlet end 234 of 30. Or space 34
0 is adjacent to the outlet end 336 of the oxidizer 320 and the inlet end 234 of the heating chamber 230 instead of the volatile organic compound oxidizer 320 for lowering the temperature at the inlet end 234 of the heating chamber 230. And is located in the heating chamber 230 itself. In any of these arrangements, a cooling means is inserted between the volatile organic compound oxidizing device 320 and the heating chamber 230 to distribute atmospheric air into the heating chamber 230 and to dispose of the inlet end 234 of the heating chamber 230. Lower the temperature.

When the device 200 is discontinued, the tubular member 2
There is a gradual reduction of production in drum 212 which must reduce heat to 50. However, the total amount of heat must be retained in the volatile organic compound oxidizer 320 for proper operation to continue during the entire work-to-stop transition. Thus, the heat is bypassed by opening the damper 350 located adjacent the outlet 336 of the volatile organic compound oxidizer 320. The damper 350 protects each component of the device 200 against excessively high temperatures during cooling by bypassing heat from the volatile organic compound oxidizer 320 away from the heating chamber 230 and thus stacks excess heat into the chimney. Another means of protecting against the effects of excessive heat opening through 354 is by heating chamber 230 and manifold 260 and at least manifold 260 and tubular member 250 located adjacent heating chamber 230.
It is preferable that the part and the part are made of a heat-resistant and corrosion-resistant alloy such as stainless steel.

The inlet end 21 of the interior 215 of the drum 212
Residual exhaust and water vapor exiting 6 is collected by means shown and formed on an auxiliary canopy 360 located adjacent inlet end 216. The duct 362 communicates with the canopy 360 and leads to the auxiliary chimney 364. In the auxiliary chimney 364, the exhaust fan 366 acts to exhaust the exhaust gas and water vapor collected in the canopy 360. The heated gas exhausted from the tubular member 250 is also directed into the auxiliary chimney 364 as shown at 368 and exhausted to the atmosphere. Alternatively, if the residual emissions contain excessive contaminants, the duct 362 may lead to the space 340 rather than the auxiliary chimney 364.

The inside 24 of the heating chamber 230 is provided to enhance the portability and universality of the apparatus 200 and for cleaning maintenance.
Burner 24 so that 2 can be operated easily

With this connecting device, the burner 240 and the volatile organic compound oxidizing device 320 can be selectively moved to and from the engaged state in which the burner 240 and the volatile organic compound oxidizing device 320 are connected to the heating chamber 230. That is, the burner 240 is attached to a wheeled trolley 370 mounted on a track 372 extending in the longitudinal direction substantially parallel to the central axis CC of the drum 212. Similarly, the volatile organic compound oxidation device 320 is attached to a wheeled carriage 374 mounted on a truck 372. The burner 240 and the device 320 are these burners 240 and the device 320.
