The hot melt tank 2 is overheadly arranged in the recovery tank 1. The bottom of the hot melt tank 2 is evenly distributed with leakage holes. The outer periphery of the hot melt tank 2 is encapsulated with a heating wire 8. The waste asphalt in the hot melt tank 2 is heated by the heating wire 8 to melt it. The melted asphalt liquid enters the hot melt tank 2 from the leakage hole, thereby separating the asphalt liquid from impurities such as stones.

Among them, the lifting seat 401 is an L-shaped seat body, and the vertical section of the lifting seat 401 is integrally formed with a horizontal horizontal plate, and the horizontal plate is penetrated from top to bottom. The recovery tank 1 is placed in the through hole, and the outer edge of the tank top of the recovery tank 1 is provided with a side shoulder, and the side shoulder pad rests on the horizontal plate to prevent the recovery tank 1 from falling down. A liquid outlet pipe 10 is provided at the bottom of the recovery tank 1, and a switch valve is installed on the liquid outlet pipe 10 to facilitate the discharge of asphalt liquid from the recovery tank 1. At the same time, the lifting seat 401 is provided with a guide groove 405 in the vertical direction, the screw shaft 403 is arranged in the guide groove 405, and is rotatably connected with the lifting seat 401 through a bearing, the lifting motor 402 is fixed to the top of the lifting seat 401, and is connected with the screw shaft 403 through a coupling, the lifting plate is threadedly connected to the screw shaft 403 and limited in the guide groove 405, and the lifting plate is integrally connected with the sealing cover 3. It is not difficult to imagine that the lifting motor 402 drives the screw shaft 403 to rotate forward and backward, so that the lifting plate is connected to the sealing cover 3 and moves up and down along the screw shaft 403.

[0040] In the above, the inner bottom surface of the recovery tank 1 is integrally formed with a support block, and the hot melt tank 2 is placed in the recovery tank 1 and attached to the top surface of the support block, so that it is suspended in the recovery tank 1 so that the asphalt liquid can enter the recovery tank 1 from the leakage hole. A packaging sleeve 9 is integrally formed on the outer wall of the hot melt tank 2, and a packaging inner cavity is formed between the packaging sleeve 9 and the hot melt tank 2. The heating chamber is located in the packaging inner cavity and is coiled around the outer wall of the hot melt tank 2. The inner wall of the packaging sleeve 9 is provided with a heat insulation layer, and the heat insulation layer is made of heat insulation materials such as polystyrene foam board, rock wool, etc., so as to minimize the heat loss in the hot melt tank 2. The heating wire 8 is connected to the electric control box 7 installed on the top surface of the sealing cover 3 through a wire, and the working state of the heating wire 8 is controlled by the electric control box 7. At the same time, the electric control box 7 also controls the lifting motor 402.

[0041] In this embodiment, in order to reduce the emission of harmful gases during the hot melting process, as Figure 1 and Figure 2As shown, the bottom of the sealing cover 3 is provided with a first sealing step portion 301 and a second sealing step portion 302, the first sealing step portion 301 and the second sealing step portion 302 are concentric and the first sealing step portion 301 is located on the inner side of the second sealing step portion 302, the first sealing step portion 301 and the second sealing step portion 302 are both covered with a rubber cushion, the first sealing step portion 301 is sealed and plugged into the tank mouth of the hot melt tank 2, the tank top of the recovery tank 1 is provided with a sealing step ring groove 101 that cooperates with the second sealing step portion 302, and the second sealing step portion 302 is plugged into the sealing step ring groove 101. At the same time, a purification box 6 is also provided on the top of the sealing cover 3, and the purification box 6 extends to the inside of the recovery tank 1 through the air pipe through the sealing cover 3, and the air pipe and the sealing cover 3 are sealed by a sealant. It can be imagined that in the process of hot melting of asphalt, harmful gases such as nitrogen oxides and sulfur dioxide will be generated, and harmful gases such as nitrogen oxides and sulfur dioxide will be removed by the purification box 6 and then discharged to reduce air pollution.

[0042] As a conventional purification method, the purification box 6 may be provided with an adsorbent, such as activated carbon, or contain ammonia water to absorb harmful gases such as nitrogen oxides and sulfur dioxide.

[0043] In a preferred embodiment, see Figure 2 As shown, the stirring mechanism 5 includes a stirring motor 501 and a stirring shaft 502. The stirring motor 501 is fixedly installed on the top side of the sealing cover 3, and the stirring motor 501 is connected to the electric control box 7. The output shaft of the stirring motor 501 is connected to the stirring shaft 502 through a coupling, and a stirring blade is provided on the stirring shaft 502.

[0044] In summary, the waste asphalt recovery device provided in the embodiment of the present application has the following usage method or working principle:

[0045] First, start the lifting motor 402 to drive the sealing cover 3 to move upward, open the recovery tank 1 and the hot melt tank 2, put the waste asphalt into the hot melt tank 2, and then use the lifting motor 402 to drive the sealing cover 3 to move downward to seal the recovery tank 1 and the hot melt tank 2;

[0046] Then, the electric heating wire 8 is started to heat and the stirring mechanism 5 is started to stir. After the waste asphalt is heated and melted, it falls into the hot melting tank 2 from the leakage hole at the bottom of the hot melting tank 2. Grain impurities such as stones remain in the hot melting tank 2. The hot melt asphalt liquid can be recycled through the liquid outlet pipe 10. The harmful gas generated during the hot melting process enters the purification box 6 to be purified and then discharged;

[0047] Finally, after the preset hot melt time is over, let it stand for a certain period of time, start the lifting motor 402 to drive the sealing cover 3 to move upward, so as to open the recovery tank 1 and the hot melt tank 2, and remove the impurities in the hot melt tank 2.

[0048] It can be seen that the waste asphalt recovery device proposed in the embodiment of the present application, by setting up a hot melt tank and a recovery tank, uses an electric heating wire to heat the waste asphalt in the hot melt tank, and continuously stirs it through a stirring device, so that the hot-melt asphalt enters the hot melt tank and is separated from debris such as gravel, and after separation, the hot melt tank and the recovery tank are opened through a lifting mechanism to dispose of the debris in the hot melt tank, thereby achieving the purpose of facilitating the recycling of waste asphalt.
