[0002] According to statistics, 70 to 90 million tons of waste asphalt mixture is generated every year due to road maintenance, and currently only about 40% is recycled. The amount of mixture used in local excavation and patching of the road surface is small, and the treatment points are scattered. The production cost of small batches of mixture produced by mixing stations is extremely high, and the construction process is long. The cooling of the mixture causes insufficient compaction, resulting in frequent quality problems in local excavation and patching. In related technologies, the local diseased area of ​​the road surface is generally milled or chiseled out, and the old material is put into a heated mixing tank or drum. After the old asphalt mixture is melted by radiation heating on the outer wall of the mixing tank or hot air heating, an appropriate amount of new asphalt softened stone is added, re-mixed, and then laid back into the original pit, leaving the mixing station to achieve local disease repair and recycling of old materials. The following technical problems exist:

[0003] (1) The batch capacity of the equipment is usually less than 1 ton, which is not suitable for continuous and large-scale operations and has low operating efficiency.

[0004] (2) When hot air is used for heating, as the temperature of the old asphalt mixture increases, a large amount of asphalt smoke will be produced and discharged along with the hot air, which can easily cause environmental pollution and secondary aging of the old asphalt mixture, affecting the quality of the recycled mixture.

DETAILED DESCRIPTION

[0039] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0041] Combine the following Figures 1 to 5 A construction device for on-site regeneration of old asphalt mixture according to an embodiment of the utility model is specifically described.

[0042] like Figures 1 to 5As shown, according to an embodiment of the utility model, an on-site regeneration construction equipment for old asphalt mixture includes: a heating drum 3, a regeneration mixing cylinder 2, a flue gas purification device 4, a kinetic energy module (hydraulic pump 6-1, generator 6-2), a new asphalt adding device 5, and a chassis body 1 loaded with various functional devices. Among them, the heating drum 3 is located at the rear of the body 1, and is used to preheat the crushed old asphalt mixture and transfer it to the regeneration mixing cylinder 2 directly below the heating drum 3. The old asphalt mixture continues to heat up in the regeneration mixing cylinder 2, and the new asphalt is added through the new asphalt adding device 5 and stirred evenly to achieve the regeneration effect. The heating drum 3 is a single drum design, including: a burner 3-7, a cylinder 3-4, a feeding and conveying mechanism 3-3, and a drum frame 3-2. Among them, the burner 3-7, the cylinder 3-4 and the feeding and conveying mechanism 3-3 are all installed on the drum frame 3-2, and the drum frame 3-2 is installed on the vehicle body 1. The cylinder 3-4 has a rotation function relative to the drum frame 3-2, and the drum frame 3-2 has a tilting function relative to the vehicle body 1. The heating drum 3 adopts a countercurrent heating method. The cylinder 3-4 is provided with a shovel 3-5 for frying the old asphalt mixture and a radiation cylinder 3-6 for auxiliary heating. The radiation cylinder 3-6 is used in conjunction with the burner 3-7 set at the discharge end of the drum. The old asphalt mixture is quickly heated in the form of hot wind energy and radiation energy, which can effectively prevent the flame from directly contacting the old asphalt mixture. On the one hand, the amount of asphalt smoke generated is small, which reduces environmental pollution. On the other hand, the secondary aging of the old asphalt is not easy to occur, which ensures the quality of the recycled asphalt mixture. Figure 4 As shown, a chain 3-8 is installed on the lifting plate 3-5 near the end of the burner 3-7, which can prevent the old asphalt mixture from sticking to the wall, better achieve the stirring of the old asphalt mixture, and increase the heating speed.

[0043] The amount of old asphalt mixture added can be measured by the rotation speed of the feeding and conveying mechanism 3 - 3 .

[0044] The tilting function of the drum frame 3-2 is realized by the lifting cylinder 3-1 installed between the drum frame 3-2 and the vehicle body 1, which can realize the rapid switching between the tilting operation and the horizontal transfer of the heating drum 3.

[0045] The flue gas purification device 4 is installed at the front of the vehicle body 1 and is arranged adjacent to the burner 3-7. It can purify the flue gas hot air generated by the burner 3-7 heating the old asphalt mixture. The flue gas purification device 4 is powered by the generator 6-2.

[0046] The new asphalt adding device 5 comprises an asphalt tank 5-1, an asphalt pump 5-4 and an asphalt spraying rod 5-5, wherein the asphalt tank 5-1 is arranged at the front side of the vehicle body 1, and an asphalt pump 5-4 is arranged on the connecting pipeline between the asphalt tank 5-1 and the asphalt spraying rod 5-5;

[0047] The hydraulic pump 6-1 is arranged on the vehicle body at the bottom of the asphalt tank 5-1, and takes power through the secondary shaft of the vehicle body engine to supply energy to the corresponding devices of the equipment; the generator 6-2 is arranged on the vehicle body 1 to supply power to the corresponding devices of the equipment.

[0048] Furthermore, the feeding and conveying mechanism 3-3 can use a tipping bucket loader to convey and lift the old asphalt mixture. The radiation tube 3-6 can use an infrared heating plate.

[0049] Furthermore, if Figures 1 to 3 As shown, the regeneration mixing cylinder 2 is designed in the form of a horizontal double-shaft mixing cylinder, specifically, two sets of horizontal agitators 2-7 with opposite rotation directions are arranged inside the cylinder body 2-8, and the stirring motor 2-4 connected to the horizontal agitator 2-7 is arranged on the front side of the vehicle body 1; in addition, the regeneration mixing cylinder 2 is also provided with a high-temperature chamber 2-6 and a discharge port 2-2, the discharge port 2-2 is located on the rear side of the vehicle body 1, the high-temperature chamber 2-6 is arranged on the outer side of the cylinder wall plate, and the high-temperature chamber 2-6 is radiated and heated by the burner 2-1 arranged on the rear side of the cylinder body.

[0050] Furthermore, if Figure 2 As shown, the discharge port 2-2 and the burner 2-1 are arranged in pairs, and the burner 2-1 is arranged on both sides of the discharge port 2-2.

[0051] Therefore, the material can be gently heated to 150±5℃ or the required production process temperature through upper and lower radiation heating of the outer wall of the regeneration mixing cylinder. The flame does not directly contact the old material during the entire heating process, which can prevent the secondary aging of the old asphalt and improve the quality of the recycled asphalt mixture.

[0052] Furthermore, if Figure 1 and Figure 3 As shown, the top of the regeneration mixing cylinder 2 is closed, a feed inlet 2-5 is provided on the top plate, and an asphalt spraying rod 5-5 is provided at the rear of the feed inlet 2-5.

[0053] Therefore, the old asphalt mixture that has been rapidly heated up in the first stage in the heating drum directly enters the regeneration mixing tank, with less heat loss. The new asphalt is added at the rear of the old asphalt mixture and mixed with the old asphalt mixture that has been gently heated up in the regeneration mixing tank, further ensuring the quality of the recycled asphalt mixture.

[0054] Furthermore, if Figures 1 to 3 As shown, a material door plate 2-2-1 is provided at the discharge port 2-2, and the material door plate 2-2-1 is designed to be arc-shaped, and the discharge port 2-2 is opened and closed by controlling the material door plate 2-2 through a discharge cylinder 2-3 installed on the vehicle body 1. The arc-shaped design of the material door plate 2-2-1 makes it easier to dump the recycled asphalt mixture in batches.

[0055] Furthermore, if Figure 1 , Figure 3 and Figure 5As shown, the asphalt tank 5-1 adopts the form of hot air heating and electric heating, wherein the electric heating component 5-3 is arranged inside the asphalt tank 5-1 and in the lower part thereof, which can better control the temperature. The hot air heating chamber 5-6 is arranged outside the wall plate of the asphalt tank 5-1, and utilizes the residual heat of the hot air filtered by the flue gas purification device 4. A vertical agitator 5-2 is set in the asphalt tank 5-1. The asphalt pump 5-4 uses a metering positive displacement pump, and the amount of new asphalt added can be measured by the rotation speed.

[0056] Thus, the hot air and flue gas generated by the heating drum are purified and fully utilized, which not only avoids environmental pollution but also saves resources. After the new asphalt is heated, it is added to the regeneration mixing cylinder and mixed with the old asphalt, which further improves the production efficiency, helps save materials, and improves the quality of the regenerated asphalt mixture. Furthermore, the flue gas purification device 4 adopts a bag dust removal device.

[0057] Furthermore, if Figures 1 to 3 As shown, the vehicle body 1 is provided with a hydraulic telescopic wall 7, which is installed on the bottom side of the vehicle body 1 and is provided at the front and rear. During operation, the telescopic wall 7 is extended to ensure safe construction of the vehicle body. The air compressor 8 is installed at the front of the vehicle body and is connected to the flue gas purification device to provide compressed air for the bag anti-vibration in the flue gas purification device (bag dust removal device).

[0058] The kinetic energy module includes a hydraulic pump 6-1 and a generator 6-2, wherein the hydraulic pump 6-1 is arranged on the vehicle body 1 at the bottom of the asphalt tank 5-1, and takes power through the auxiliary shaft of the engine of the vehicle body 1 to supply power to the horizontal agitator 2-7, the lifting cylinder 3-1, the unloading cylinder 2-3, the asphalt pump 5-4, the feed conveying device 3-3, the hydraulic telescopic wall 7 and the vertical agitator 5-2; the generator 6-2 is used by the flue gas purification device 4, the burner 2-1, the burner 3-7, the air compressor 8, the feed conveying device 3-3 and the asphalt tank electric heating component 5-3.

[0059] The working process of the on-site regeneration construction equipment for old asphalt mixture proposed by the utility model is as follows:

[0060] Adjust the position of the on-site recycling construction equipment for old asphalt mixture, and control the heating drum to be in a tilted working state through the lifting cylinder; put the old asphalt mixture into the heating drum through the feeding and conveying mechanism, and use the burner and the radiation tube to quickly heat the old asphalt mixture to 100±5℃ through hot air radiation countercurrent heating while the heating drum rotates; the old asphalt mixture flows directly into the regeneration mixing cylinder after flowing out of the heating drum, and the burner and the high-temperature chamber are used to radiate heat to the bottom and top of the outer wall of the regeneration mixing cylinder, and two sets of horizontal agitators with opposite rotation directions are used to mix the materials so that the materials continue to heat up to 150±5℃ or the required production process temperature; new asphalt is added to the regeneration mixing cylinder through the asphalt spray rod, and the regeneration mixture is continued to be mixed in the regeneration mixing cylinder before being discharged from the discharge port.
