[0020] The beneficial effects of the present invention are as follows:

[0021] 1. By providing an exhaust gas separation mechanism in the present invention, after heating the asphalt by using the auxiliary component, it is necessary to first open the sealing plate on the side close to the adsorption unit and connect the rolling curtain device to the docking plate to allow the exhaust gas to enter the pretreatment mechanism. Then, the exhaust gas will enter the refrigerator through the first air pipe. The refrigerator will control the cooling of the cooling pipe and reduce the temperature to -10°C, and then reduce it to -30°C after a period of time, so that high-boiling-point and medium- and low-boiling-point VOCs are all condensed into a liquid state and flow into the collection box from the liquid outlet, facilitating subsequent recycling and realizing the separation of natural gas and VOCs.

[0022] 2. By providing a shoveling mechanism in the present invention, acidic gases (such as SO2 and NOx generated by combustion) in the exhaust gas combine with condensed water to form acid solution, which will corrode the cooling pipe in the refrigerator. Therefore, the first servo motor drives the reciprocating lead screw to rotate, so that the moving block moves and drives the scraping ring to shovel off the ice layer condensed on the cooling pipe, avoiding the ice layer melting when the refrigerator is not working and combining with a small amount of acidic gas remaining in the refrigerator to form acid solution, thereby corroding the cooling pipe and the refrigerator.

[0023] 3. By providing a shoveling mechanism in the present invention, since the shoveling mechanism does not operate continuously, ice layers may also be generated between the scraping ring and the cooling pipe when it is not working, hindering the subsequent movement of the scraping ring. Therefore, the micro motor drives the rotating rod to rotate reciprocally at a certain angle, so that the impact block collides with the scraping ring, and then the ice layer between the scraping ring and the cooling pipe is broken by vibration. It is also possible to adsorb the magnetic block by the way that the electromagnet regularly generates magnetic forces with different magnetisms, driving the impact block to collide with the scraping ring.

[0024] 4. By providing a pretreatment mechanism in the present invention, the air extractor will suck the exhaust gas into the ventilation plate, and the filter plate will isolate the dust impurities in the exhaust gas. Every once in a while, by pulling the handle plate, the filter plate is taken out and cleaned, and then inserted into the ventilation plate to avoid the weakening of the filtering effect.

Detailed implementation manners

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles of the present invention and its practical applications, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0036] Embodiment 1, using Figures 1-9 An environmentally friendly asphalt discharging device for road construction according to an embodiment of the present invention will be described as follows.

[0037] As Figures 1-2 shown, an environmentally friendly asphalt discharging device for road construction of the present invention includes a support frame 1, moving wheels 2 that can drive the overall device to move, a storage barrel 3 for storing asphalt, and a placement table 8 for placing the storage barrel 3, and further includes:

[0038] An adsorption unit 7 provided on one side of the support frame 1 for absorbing and separating the discharged tail gas, and an auxiliary component 6 provided on the top of the support frame 1 for assisting in discharging.

[0039] When the present invention is working, first, the asphalt material is put into the storage barrel 3. After the overall device moves to the position where discharging is required, the adsorption unit 7 will first collect the tail gas generated by heating the asphalt, and then the auxiliary component 6 will assist in discharging.

[0040] As Figures 3-4 shown, the adsorption unit 7 includes a front end plate 71. On both sides of the front end plate 71, there are curtain rolling devices 72. On the curtain rolling devices 72, there are embedded plates 73. On the front end plate 71, there is also a hydraulic device 74. The hydraulic device 74 drives a telescopic rod 75. The top of the telescopic rod 75 is fixedly connected to a treatment box 76. At the bottom of the treatment box 76, there is a pretreatment mechanism 77 that can isolate dust and impurities. Inside the treatment box 76, there is a tail gas separation mechanism 78. On the outside of the treatment box 76, there is a removal plate 79. After the removal plate 79 is removed, it is used to replace the filter element in the tail gas separation mechanism 78. On both sides of the treatment box 76, there are docking plates 710 that can be inserted into the embedded plates 73 symmetrically;

[0041] When discharging is required, the hydraulic device 74 will also drive the telescopic rod 69 to extend upward to facilitate the tilting of the storage barrel 3.

[0042] As Figures 5-6As shown in the figure, the tail gas separation mechanism 78 includes a refrigerator 781. At the bottom of the refrigerator 781, there is a first air pipe 782 connected to the pretreatment mechanism 77. At the top of the refrigerator 781, there is a second air pipe 783. At the bottom of the refrigerator 781, there is also a liquid outlet 785. Inside the refrigerator 781, there is a refrigeration pipe 786. On the refrigeration pipe 786, there is a scraping mechanism 787. On the second air pipe 783, there is a control valve 784. At the end of the second air pipe 783 away from the refrigerator 781, there is an adsorption chamber 788. Inside the adsorption chamber 788, there are multiple layers of activated carbon plates 789. On the outer surface of the adsorption chamber 788, there is a third air pipe 7810. At the end of the third air pipe 7810 away from the adsorption chamber 788, there is a compressor 7811. On the outer surface of the compressor 7811, there is a gas pipeline 7812.

[0043] During the process of heating asphalt by using natural gas, there will be some natural gas that does not burn completely, so the generated waste gas often contains unburned natural gas (mainly composed of alkanes such as methane) and high-concentration volatile organic compounds (VOCs). After heating the asphalt by using the auxiliary component 6, it is necessary to first open the sealing plate 64 close to the adsorption unit 7 and connect the rolling curtain device to the docking plate 710 so that the tail gas enters the pretreatment mechanism 77. Then, the tail gas will enter the refrigerator 781 through the first air pipe 782. The refrigerator 781 will control the refrigeration pipe 786 to become cold and reduce the temperature to -10°C. After a period of time, it will be reduced to -30°C, so that the high-boiling-point and medium- and low-boiling-point VOCs are all condensed into liquid state and flow into the collection box through the liquid outlet 785, which is convenient for subsequent recycling and realizes the separation of natural gas and VOCs.

[0044] After separation, the control valve 784 will make the natural gas enter the adsorption chamber 788 and adsorb the remaining VOCs after adsorption separation through the activated carbon plates 789. Since natural gas has a weak molecular polarity and poor adsorption ability, it directly passes through the adsorption layer to become purified gas. The purified natural gas can be pressurized and stored by the compressor 7811, recycled for use as fuel for the asphalt heating furnace, or connected to the gas pipeline 7812 in the factory area to realize energy recycling.

[0045] On both sides of the storage barrel 3, there are openings for putting in and discharging asphalt. On both sides of the storage barrel 3, there are wheel rings 4 symmetrically arranged and adapted to the placement table 8. In the middle of the storage barrel 3, there is a tooth block 5.

[0046] The bottom of the front end plate 71 is fixedly connected to one side of the support frame 1. The top of the refrigerator 781 is fixedly connected to the inner wall of the processing box 76.

[0047] The refrigerator 781 has the functions of primary condensation and secondary condensation, condensing high-boiling-point VOCs and medium- and low-boiling-point VOCs respectively;

[0048] During the condensation process, the control valve 784 blocks the exhaust gas from passing through the second trachea 783.

[0049] As Figure 7 shown, the scraping mechanism 787 includes a first servo motor 7871. The output end of the first servo motor 7871 is fixedly connected to a reciprocating lead screw 7872. A moving block 7873 is threadedly connected to the outer surface of the reciprocating lead screw 7872. Support rods 7874 are symmetrically arranged on the upper and lower sides of the moving block 7873. One end of the support rod 7874 is fixedly connected to a scraping ring 7875. An electromagnet 7876 is arranged on the scraping ring 7875. A first support plate 7877 is arranged between the two scraping rings 7875. A rotating rod 7878 is rotatably connected to the outer surface of the first support plate 7877. One end of the rotating rod 7878 is fixedly connected to an impact block 7879. A magnetic block 78710 is arranged on the inner wall of the impact block 7879. A micro motor 78711 is also arranged on the first support plate 7877.

[0050] The exhaust gas contains acidic gases, which combine with the condensed water to form acid solution, and will corrode the refrigeration pipes 786 in the refrigerator 781. Therefore, the first servo motor 7871 drives the reciprocating lead screw 7872 to rotate, so that the moving block 7873 moves and drives the scraping ring 7875 to scrape off the ice layer condensed on the refrigeration pipe 786, avoiding the ice layer from melting when the refrigerator 781 is not working and combining with the small amount of acidic gases remaining in the refrigerator 781 to form acid solution, thereby causing corrosion to the refrigeration pipe 786 and the refrigerator 781.

[0051] Since the scraping mechanism 787 does not operate continuously, ice layers may also be generated between the scraping ring 7875 and the refrigeration pipe 786 when it is not working, which will hinder the subsequent movement of the scraping ring 7875. Therefore, the micro motor 78711 drives the rotating rod 7878 to reciprocate at a certain angle, so that the impact block 7879 collides with the scraping ring 7875, and then the ice layer between the scraping ring 7875 and the refrigeration pipe 786 is broken by vibration. It is also possible to adsorb the magnetic block 78710 by the way that the electromagnet 7876 regularly generates magnetic forces with different magnetic properties, driving the impact block 7879 to collide with the scraping ring 7875.

[0052] The outer surface of the first servo motor 7871 is fixedly connected to the outer surface of the refrigerator 781. The output end of the micro motor 78711 is fixedly connected to one end of the rotating rod 7878. The micro motor 78711 can drive the rotating rod 7878 to reciprocate;

[0053] The electromagnet 7876 will adsorb the magnetic block 78710 after being powered on. The magnetic properties of the two electromagnets 7876 are different and can be replaced.

[0054] As Figure 8As shown in the figure, the pretreatment mechanism 77 includes a ventilation plate 771. An air inlet 772 is provided at the bottom of the ventilation plate 771, and an air extractor 773 is provided at the air inlet 772. Handle plates 774 are evenly arranged on the ventilation plate 771, and a filter plate 775 is fixedly connected to the outer surface of the handle plate 774. An air outlet 776 is provided at the top of the ventilation plate 771.

[0055] The top of the ventilation plate 771 is fixedly connected to the bottom of the treatment box 76, and the air outlet 776 communicates with the bottom of the first trachea 782.

[0056] The air extractor 773 sucks the tail gas into the ventilation plate 771, and the filter plate 775 isolates the soot impurities in the tail gas. Every once in a while, by pulling the handle plate 774, the filter plate 775 is taken out and cleaned, and then inserted into the ventilation plate 771 to avoid the weakening of the filtering effect.

[0057] The specific working process is as follows:

[0058] During operation, the tail gas enters the pretreatment mechanism 77, and the filter plate 775 isolates the soot impurities in the tail gas. Then the tail gas enters the refrigerator 781 through the first trachea 782. The refrigerator 781 controls the cooling pipes 786 to become cold and reduces the temperature to -10°C. After a period of time, it is further reduced to -30°C, so that the VOCs with high boiling points and medium and low boiling points are all condensed into liquids and flow into the collection box from the liquid outlet 785. During the condensation process, the first servo motor 7871 drives the reciprocating lead screw 7872 to rotate, so that the moving block 7873 moves and drives the scraping ring 7875 to scrape off the ice layer condensed on the cooling pipe 786, avoiding the ice layer from melting when the refrigerator 781 is not working and combining with the small amount of acidic gas remaining in the refrigerator 781 to form acid liquid, thereby corroding the cooling pipe 786 and the refrigerator 781.

[0059] Embodiment 2, use Figures 1-9 An environmentally friendly road construction asphalt discharging device according to an embodiment of the present invention will be described as follows.

A flame spraying device 65 is arranged on the sealing plate 64 close to the adsorption unit 7, and a nozzle 66 is arranged on the flame spraying device 65;

[0061] During the heating process, the sealing plates 64 on both sides will fit with the storage barrel 3, and then the flame spraying device 65 will ignite the introduced natural gas and heat the asphalt.

[0062] The auxiliary component 6 further includes a supporting bottom rod 67. A second hydraulic device 68 is fixedly connected to the bottom of the supporting bottom rod 67. The second hydraulic device 68 drives a second telescopic rod 69. A push plate 610 is fixedly connected to the top of the second telescopic rod 69.

[0063] When discharging is required, the second hydraulic device 68 will drive the second telescopic rod 69 to extend upward and cause the storage barrel 3 to tilt at a certain angle, facilitating the discharge of asphalt from the other side.

[0064] The bottom of the side frame 61 is fixedly connected to the top of the support frame 1. The supporting bottom rod 67 is arranged on the side close to the adsorption unit 7. The top of the supporting bottom rod 67 is fixedly connected to the bottom of the support frame 1.
