This method not only consumes energy but also wastes the energy of the asphalt waste heat, and does not realize the full utilization of the asphalt heat energy.

[0003] Among them, the publication (announcement) number: CN219693216U discloses a steam generator using asphalt waste heat, which includes a large head and a small head. A plurality of asphalt pipes are connected between the large head and the small head, and a shell is arranged outside the asphalt pipes; an asphalt inlet and an asphalt outlet are arranged on the large head, a water inlet and a water outlet are arranged on the shell, and the water inlet is connected to a water tank through a water inlet pipe; the top of the shell is connected to a steam drum through a steam riser pipe, and the steam drum is connected to the water tank through a condensate downcomer pipe; heat dissipation fins are arranged on the asphalt pipes, a liquid level gauge is arranged inside the shell, and a valve is arranged on the water inlet pipe.

[0004] In the above scheme, the asphalt is directly introduced into the interior of the shell. However, due to the poor fluidity of the asphalt, the asphalt is easily blocked inside the pipeline, resulting in poor asphalt waste heat recovery effect. Therefore, a modified asphalt waste heat steam generating device is proposed. Content of the Utility Model

The air inlet end and the air outlet end of the heat conduction pipes both extend to the outside of the shell, and a connecting pipe is fixedly arranged on the air inlet pipe of the heat conduction pipes. One end of the connecting pipe away from the heat conduction pipes is fixedly provided with an air extraction pump, and a heat absorption cover is fixedly arranged at the bottom of the air extraction pump. Fixed mechanisms are arranged on both sides of the heat absorption cover; a water adding pipe and a steam pipe are fixedly arranged at the top of the shell, and a disturbance mechanism is arranged at the bottom of the shell.

[0008] Preferably, a fixing frame is fixedly arranged inside the shell, and the heat conduction pipes are fixedly arranged inside the fixing frame.

[0009] Preferably, the heat conduction pipes adopt serpentine pipes.

[0010] Preferably, the connecting pipe adopts a metal bellows.

[0011] Preferably, the housing is a heat-insulating housing.

[0012] Preferably, the fixing mechanism includes a screw rod, a clamping plate and a turntable. The screw rod is horizontally threaded on the side wall of the heat absorption cover. One end of the screw rod is rotatably connected to the clamping plate, and one end of the screw rod is fixedly connected to the turntable.

[0013] Preferably, a lifting support frame is fixedly provided at the top of the housing.

[0014] Preferably, the disturbing mechanism includes a motor, a rotating shaft, disturbing blades, belt pulleys and a belt. The rotating shafts are symmetrically and rotatably arranged at the bottom of the housing.

The motor is fixedly arranged on one side of the lifting support frame, and the output end of the motor is fixedly connected to the lower end of one of the rotating shafts.

[0015] Preferably, the shaft wall of the rotating shaft and the bottom of the housing are rotatably connected through a sealed bearing.

[0016] Compared with the prior art, the present utility model provides a modified pitch waste heat steam generating device, which has the following beneficial effects:

[0017] 1. By providing a heat conduction tube, a connecting tube, an air extraction pump and a heat absorption cover, the heat absorption cover can be inserted into the top opening of the asphalt heating tank. The hot air can be sucked by the air extraction pump, and then discharged into the interior of the heat conduction tube through the connecting tube. Since the heat conduction tube is in contact with the water inside the housing, it can heat the water inside the housing and generate steam, realizing the function of waste heat recovery. The generated steam is discharged through a steam pipe for use.

[0018] 2. By providing a screw rod, a clamping plate and a turntable, after the heat absorption cover is inserted into the top opening of the asphalt heating tank, then the hand rotates the turntable. The turntable drives the screw rod to rotate and makes the clamping plate abut against the side wall of the asphalt heating tank, so that the heat absorption cover can be firmly installed on the top of the asphalt heating tank.

[0019] 3. By providing a motor, a rotating shaft, disturbing blades, belt pulleys and a belt, when the motor works, it can drive one of the rotating shafts to rotate. Since the two rotating shafts are connected by belt pulleys and a belt in a transmission manner, the two disturbing blades can be made to rotate synchronously, which can increase the fluidity of the water inside the housing and improve the heating efficiency.

[0020] The parts not involved in this device are the same as or can be implemented by the prior art. The present utility model sucks the waste heat of the modified pitch and heats the water, making the water inside the housing in a steam state, and having a disturbing structure, which improves the efficiency of generating modified pitch waste heat steam.
